    The aim of the study was to determine the prevalence of orthorexia nervosa among the performance artists in the State Opera and Ballet and in the Bilkent University Symphony Orchestra. The study population consisted of 39 men and 55 women for a total of 94 artists with mean age of 33 years. The ORTO-15 test was used to determine the prevalence of orthorexia nervosa. Those subjects who scored below 40 in the ORTO-15 test were classified as having orthorexia nervosa. Mean score of the participants in the ORTO-15 test was 37.9+/-4.46. A total of 56.4% of the artists involved in the research scored below 40 in the ORTO-15 test. While the highest prevalence of orthorexia nervosa was recorded among opera singers (81.8%), it was 32.1% among ballet dancers and 36.4% among symphony orchestra musicians. The differences between the three groups were statistically significant. No difference was noted between mean ORTO-15 score by baseline characteristics as gender, age, educational level, work experience, body mass index, smoking and alcohol consumption. The research group have a higher socio-economic and education level than the majority of the general public in Turkey. Additionally, being an artist in Turkey means being a role model for the general public both in terms one's physical appearance and lifestyle. These may be the reason why artists are more sensitive to this issue.

    In this work, the effectiveness of nanocomposite surface treatments as protective systems for artistic stones was evaluated. Pyrolitic silica and titania nanoparticles were dispersed in a commercial silicon-based polymer and applied on marble and travertine samples. Artificial aging processes, both in climatic chamber and in solar box, were carried out to simulate real degradation processes in terms of photo-thermal effects and physical-chemical damage. The performances of the nanocomposites used as consolidant were evaluated comparatively by means of diverse diagnostic techniques, namely: scanning electron microscopy (SEM), laser induced fluorescence (LIF), ultrasonic technique, colorimetry, total immersion water absorption and contact angle. The results show that some properties of conservation materials can be improved by the presences of nanoparticles because they induce substantial changes of surface morphology of the coating layer and counter the physical damage observed during artificial weathering

    Full Text Available Abstract In France, the curricula for physical education (PE place gymnastic activities in a set of competences named “Achieving a corporal performance for artistic and acrobatic aims”, alongside dance and circus arts. What place does Artistic occupy in gymnastic activities? Is an aesthetic gesture sufficient to be considered as part of an artistic activity? Defining the term «Artistic» is difficult in the field of sports, as descriptions usually come from the technique/Artistic dichotomy. Our analysis focuses on rhythmic gymnastics (RG, which is precisely seen as emblematic of this technique/Artistic division: on the one hand, technical rigor, prescriptions and rules; on the other hand, grace, creation and self-expression. We believe such compartmentalized categories are too schematic to define gymnasts’ and students’ activities, so we will examine their articulation points. We first present an overview of RG as a school practice in ordinary forms of teaching, then an historical analysis of RG as a sports practice, to highlight the unbridgeable gap between both school and sports practices, regarding technique/Artistic connections. We then propose three significant points of articulation (called games closely combining technical requirements and artistic commitment. We consider that the variation of the three games played in GR (creating, making beautiful, representing is the product of historical dynamics of this sport we call artistic. Finally, on this basis, we propose a learning game for novice students promoting the artistic quality of RG practice.

    2017-12-01

    Previous literature on dancers and athletes has shown a large impact of eating disorders (EDs) on these individuals, but there is limited research on EDs affecting non-dance performing artists (i.e., musicians, actors, etc.). This systematic review aimed to identify and evaluate the literature on EDs in non-dance performing artists. A systematic review of the literature was performed on 24 databases, using search terms related to EDs and non-dance performing artists. All results from the databases were systematically screened for inclusion and exclusion criteria. The initial search returned 86,383 total articles, which after screening and removal of duplicates and irrelevant papers yielded 129 results. After screening the 129 full-text results for eligibility, 10 studies met criteria for inclusion: 6 papers addressed EDs in musicians, and 4 papers addressed EDs in theatre performers. Most studies used questionnaires and body mass index (BMI) as diagnostic tools for EDs. Most were small-scale studies and participants were mostly students. Because of the studies' heterogeneity and varying quality, the results obtained were often contradictory and questionable. Although there has been a lot of literature in dancers, we found relatively few studies associating EDs with other performing artists, and most were inconsistent in their information.

    Several studies have addressed visuospatial and executive skills in artistic activities in Frontotemporal Lobar Degeneration (FTLD) and Alzheimer's disease (AD). To investigate the performance of FTLD patients compared to controls on two artistic tasks. Four FTLD patients with mean age of 57 (8.7) years and schooling of 12.2 (4.5) years plus 10 controls with mean age of 62.9 (8.6) years and schooling of 12.3 (4.6) years, were assessed using the Lowenstein Occupational Therapy Cognitive Assessment (LOTCA) and by a three-stage artistic protocol including visual observation, copying and collage, based on a Sisley painting. FTLD patients had lower scores than controls on Visuospatial Perception, Copy, Collage, Examiner's Observation, and Total, showing distinct patterns of performance according to FTLD sub-type: semantic PPA, nonfluent PPA and bvFTD. FTLD patients presented impairment in the visuospatial and executive skills required to perform artistic tasks. We demonstrated that the application of the instrument as a complimentary method for assessing cognitive skills in this group of patients is possible. Further studies addressing larger and more homogeneous samples of FTLD patients as well as other dementias are warranted.

    2018-05-01

    The goal of this study was to identify knowledge gaps in clinicians who evaluate and treat performing artists for illnesses and injuries that affect vocal function in college health settings. This pilot study utilized a web-based cross-sectional survey design incorporating common clinical scenarios to test knowledge of evaluation and management strategies in the vocal performing artist. A web-based survey was administered to a purposive sample of 28 clinicians to identify the approach utilized to evaluate and treat vocal performing artists in college health settings, and factors that might affect knowledge gaps and influence referral patterns to voice specialists. Twenty-eight clinicians were surveyed, with 36% of respondents incorrectly identifying appropriate vocal hygiene measures, 56% of respondents failing to identify symptoms of vocal fold hemorrhage, 84% failing to identify other indications for referral to a voice specialist, 96% of respondents acknowledging unfamiliarity with the Voice Handicap Index and the Singers Voice Handicap Index, and 68% acknowledging unfamiliarity with the Reflux Symptom Index. The data elucidated specific knowledge gaps in college health providers who are responsible for evaluating and treating common illnesses that affect vocal function, and triaging and referring students experiencing symptoms of potential vocal emergencies. Future work is needed to improve the standard of care for this population. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    The purpose of this study was to investigate the acute effects of 3 different warm up methods of stretching (static, proprioceptive neuromuscular facilitation, and stretching exercises on a Vibration platform) on flexibility and legs power-jumping performance in competitive artistic gymnasts. Eighteen competitive artistic gymnasts were recruited to participate in this study. Subjects were exposed to each of 3 experimental stretching conditions: static stretching (SS), proprioceptive neuromuscular facilitation stretching (PNF), and stretching exercises on a Vibration platform (S+V). Flexibility assessed with sit and reach test (S & R) and jumping performance with squat jump (SJ) and counter movement jump (CMJ) and were measured before, immediately after and 15 min after the interventions. Significant differences were observed for flexibility after all stretching conditions for S+V (+1.1%), SS (+5.7%) and PNF (+6.8%) (P=0.000), which remained higher 15 min after interventions (S+V (1.1%), SS (5.3%) and PNF (5.5%), respectively (P=0.000). PNF stretching increased flexibility in competitive gymnasts, while S+V maintained jumping performance when both methods were used as part of a warm-up procedure.

  1. Mixing students and performance artists to provide innovative ways of communicating scientific research

    In May 2007 the Open University (U.K.) in conjunction with the MK (Milton Keynes) Gallery invited performance artists Noble and Silver to work with a group of students to design innovative methods of disseminating their research to a general audience. The students created a multitude of well-received live and multimedia performances based on their research. Students found they greatly benefited from the artists' and each others' different viewpoints and backgrounds, resulting in improved communication skills and varying interpretations of their own topic of interest. This work focuses on research aimed at identifying precursory activity at volcanoes using temperature, earthquake and ground movement data, to aid improvement of early warning systems. For this project an aspect of the research relevant to the public was chosen: the importance of appropriately timed warnings regarding the possibility of an eruption. If a warning is issued too early it may cause complacency and apathy towards the situation, whereas issuing a warning too late may endanger lives and property. An interactive DVD was produced which leads the user through the events preceding a volcanic eruption. The goal is to warn the public about the impending eruption at the most appropriate time. Data is presented in short film clips, after which questions are posed. Based on the player's answers the consequences or follow-up events of the choices are explored. We aim to improve and expand upon this concept in the near future, as well as making the DVD available to schools for educational purposes.

  2. The extraordinary case of Russian performance artist Pyotr Pavlensky: Psychopathology or contemporary art?

    2018-01-01

    This article examines the psychiatric and political issues surrounding the case of the controversial Russian performance artist Pyotr Pavlensky, who received a number of court-ordered psychiatric evaluations as part of the legal actions initiated subsequent to his political protest actions. The author presents the results of his own clinical investigation into Pavlensky's case, arguing that previous diagnoses made by psychiatrists were unwarranted and unreasonable. This case draws the attention of experts to a problem: the need for more accurate criteria for the differentiation of behavioral disorders from behavior understood locally as socially-deviant. This issue is especially relevant during the assessment of the mental health of persons engaged in socially transgressive behavior which is explicitly framed as aesthetic and political action.

    Planar supercapacitors with high flexibility, desirable operation safety, and high performance are considered as attractive candidates to serve as energy-storage devices for portable and wearable electronics. Here, a scalable and printable technique is adopted to construct novel and unique hierarchical nanocoral structures as the interdigitated electrodes on flexible substrates. The as-fabricated flexible all-solid-state planar supercapacitors with nanocoral structures achieve areal capacitance up to 52.9 mF cm -2 , which is 2.5 times that of devices without nanocoral structures, and this figure-of-merit is among the highest in the literature for the same category of devices. More interestingly, due to utilization of the inkjet-printing technique, excellent versatility on electrode-pattern artistic design is achieved. Particularly, working supercapacitors with artistically designed patterns are demonstrated. Meanwhile, the high scalability of such a printable method is also demonstrated by fabrication of large-sized artistic supercapacitors serving as energy-storage devices in a wearable self-powered system as a proof of concept. © 2017 WILEY-VCH Verlag GmbH & Co.

    2016-01-01

    As the Arts@CERN programme testifies, CERN is no stranger to the collision of science and art. Just before Christmas, the Slovak artist Ján Zoričák exhibited his glass artworks at CERN, some of which make use of crystals from the OPAL experiment. We take a look at the artist, the science that inspired him and the techniques that he uses.   It took 10 months to create the 22 glass artworks in the exhibition, six of which make use of lead glass from the calorimeter of OPAL, one of the four main LEP experiments. Ján Zoričák has been a glass sculptor for several decades. In his capable hands, glass seems to take on a new energy, as he uses the contrast in temperature when glass heated for up to 48 hours at extremely high temperatures is exposed to a very cold source until it fractures. The resulting cracks break up the homogeneity and regularity of the glass and play with light and shadow, an effect that is majestically reinforced by finishing and polish...

    The objectives of this study were to examine common patterns in the lives and artwork of five artistic savants previously described and to report on the clinical, neuropsychological, and neuroimaging findings from one newly diagnosed artistic savant. The artistic savant syndrome has been recognized for centuries, although its neuroanatomic basis remains a mystery. The cardinal features, strengths, and weaknesses of the work of these six savants were analyzed and compared with those of children with autism in whom artistic talent was absent. An anatomic substrate for these behaviors was considered in the context of newly emerging theories related to paradoxical functional facilitation, visual thinking, and multiple intelligences. The artists had features of "pervasive developmental disorder," including impairment in social interaction and communication as well as restricted repetitive and stereotyped patterns of behavior, interest, and activities. All six demonstrated a strong preference for a single art medium and showed a restricted variation in artistic themes. None understood art theory. Some autistic features contributed to their success, including attention to visual detail, a tendency toward ritualistic compulsive repetition, the ability to focus on one topic at the expense of other interests, and intact memory and visuospatial skills. The artistic savant syndrome remains rare and mysterious in origin. Savants exhibit extraordinary visual talents along with profound linguistic and social impairment. The intense focus on and ability to remember visual detail contributes to the artistic product of the savant. The anatomic substrate for the savant syndrome may involve loss of function in the left temporal lobe with enhanced function of the posterior neocortex.

  17. The Artistic Infant Directed Performance: A Mycroanalysis of the Adult's Movements and Sounds.

    Español, Silvia; Shifres, Favio

    2015-09-01

    Intersubjectivity experiences established between adults and infants are partially determined by the particular ways in which adults are active in front of babies. An important amount of research focuses on the "musicality" of infant-directed speech (defined melodic contours, tonal and rhythm variations, etc.) and its role in linguistic enculturation. However, researchers have recently suggested that adults also bring a multimodal performance to infants. According to this, some scholars seem to find indicators of the genesis of the performing arts (mainly music and dance) in such a multimodal stimulation. We analyze the adult performance using analytical categories and methodologies of analysis broadly validated in the fields of music performance and movement analysis in contemporary dance. We present microanalyses of an adult-7 month old infant interaction scene that evidenced structural aspects of infant directed multimodal performance compatible with music and dance structures, and suggest functions of adult performance similar to performing arts functions or related to them.

When the group asks the mother to wean her baby, the better to share equally the responsibility of childrearing, the mother cries. The mother does not want to wean her child. The mother wants to be the primary caregiver. For the mother, this is the moment when the psychoanalytic enters the discourse, no Marx without Freud, no Lacan without Kristeva: in the new world, universal childcare will be necessary but not sufficient. The mother is Mary Kelly, the artist whose early career would cohere around soiled diapers, and whose practice has always been profoundly on the side of the maternal.

    To describe the clinical, neuropsychological, and imaging features of five patients with frontotemporal dementia (FTD) who acquired new artistic skills in the setting of dementia. Creativity in the setting of dementia has recently been reported. We describe five patients who became visual artists in the setting of FTD. Sixty-nine FTD patients were interviewed regarding visual abilities. Five became artists in the early stages of FTD. Their history, artistic process, neuropsychology, and anatomy are described. On SPECT or pathology, four of the five patients had the temporal variant of FTD in which anterior temporal lobes are involved but the dorsolateral frontal cortex is spared. Visual skills were spared but language and social skills were devastated. Loss of function in the anterior temporal lobes may lead to the "facilitation" of artistic skills. Patients with the temporal lobe variant of FTD offer a window into creativity.

  4. [Artistic creativity and dementia].

    Artistic creativity can be defined as the ability to produce both innovative and esthetic works. Though most dementias result in a loss of instrumental functions and a deterioration in artistic production, for some established artists, dementia, most often Alzheimer's disease, changed their style and technique but preserved their creativity and prolific artistic drive. Moreover, in some cases, mainly frontotemporal dementia, Parkinson's disease, and very occasionally strokes, the disease may favour the emergence of de novo artistic talent. This phenomenon has been conceptualized as a paradoxical facilitation, a disinhibition of brain areas devoted to visuospatial processing, greater freedom in a patient who becomes less bound by social conventions, enhancement of motivation and pleasure, etc. These neurological cases provide an opportunity to shed some light on the roots of artistic creation.

    Full Text Available The steadily increasing demand for artistic professions brings to the fore the task of studying the phenomenon of art by researching the unique capacity of the human brain to create works of art in different spheres of creative activity. So far, only a few studies have investigated creativity-related brain activity in representatives of the creative professions. The aim of the empirical research was to study the neurophysiological correlates of artistic image creation by representatives of the artistic professions. The participants were 60 right-handed females aged 23-27, divided into three groups— artists (23 people, actors (17 people, and specialists who do not work in an artistic field (20 people. The mono-typing technique was used to model the creative artistic process. EEG signals were recorded in a resting state, and during four stages of the creation of an artistic image (viewing of monotypes, frustration, image creation, and thinking over the details from 21 electrodes set on the scalp according to the International 10-20 System. We analyzed EEG coherence for each functional trial at theta (4.00–8.00 Hz, alpha1 (8.00–10.5 Hz, alpha2 (10.5–13.00 Hz, and beta (13.00– 35.00 Hz frequency bands. For statistical analysis, we used MANOVA and post hoc analysis. We found that the neurophysiological correlates of creating an artistic image are different at different stages of the creative process, and have different features for artists and actors. The actors primarily show dominance of right hemisphere activity, while close interaction of the hemispheres distinguishes the brains of the artists. The differences revealed in brain cortex functioning when artists or actors create an artistic image reflect different strategies of imaginative creative work by representatives of these professions.

  6. Artistic creativity, artistic production, and aging.

    Mazzucchi, Anna; Sinforiani, Elena; Boller, François

    2013-01-01

    This chapter reviews the changes produced by age on various aspects of artistic painting, particularly creativity and actual production. Aging in trained painters is often accompanied by a decline in creativity, which in turn is due to the cognitive decline related to aging. It has been argued, however, that aging does not cause a decline, but only changes in style and content. The two views are not mutually exclusive, and we present examples illustrating both aspects. We also show that, in addition to cognitive changes, impairment of sensory organs, especially vision, and of the bones and joints, may also produce marked changes in an artist's production and style. We conclude by showing that finding ways to induce creativity in persons who do not consider themselves artists can be a way of stimulating creativity and contribute to successful aging. © 2013 Elsevier B.V.

  7. Learning templates for artistic portrait lighting analysis.

    2015-02-01

    Lighting is a key factor in creating impressive artistic portraits. In this paper, we propose to analyze portrait lighting by learning templates of lighting styles. Inspired by the experience of artists, we first define several novel features that describe the local contrasts in various face regions. The most informative features are then selected with a stepwise feature pursuit algorithm to derive the templates of various lighting styles. After that, the matching scores that measure the similarity between a testing portrait and those templates are calculated for lighting style classification. Furthermore, we train a regression model by the subjective scores and the feature responses of a template to predict the score of a portrait lighting quality. Based on the templates, a novel face illumination descriptor is defined to measure the difference between two portrait lightings. Experimental results show that the learned templates can well describe the lighting styles, whereas the proposed approach can assess the lighting quality of artistic portraits as human being does.

    Artistic ability and creativity are defining characteristics of human behavior. Behavioral neurology, as a specialty, believes that even the most complex behaviors can be modeled and understood as the summation of smaller cognitive functions. Literature from individuals with specific brain lesions has helped to map out these smaller regions of cognitive abilities. More recently, models based on neurodegenerative conditions, especially from the frontotemporal dementias, have allowed for greater nuanced investigations into the various functional anatomies necessary for artistic behavior and possibly the underlying networks that promote creativity. © 2013 Elsevier B.V.

  4. Dentate Gyrus circuitry features improve performance of sparse approximation algorithms.

    Directory of Open Access Journals (Sweden)

    Panagiotis C Petrantonakis

    Full Text Available Memory-related activity in the Dentate Gyrus (DG is characterized by sparsity. Memory representations are seen as activated neuronal populations of granule cells, the main encoding cells in DG, which are estimated to engage 2-4% of the total population. This sparsity is assumed to enhance the ability of DG to perform pattern separation, one of the most valuable contributions of DG during memory formation. In this work, we investigate how features of the DG such as its excitatory and inhibitory connectivity diagram can be used to develop theoretical algorithms performing Sparse Approximation, a widely used strategy in the Signal Processing field. Sparse approximation stands for the algorithmic identification of few components from a dictionary that approximate a certain signal. The ability of DG to achieve pattern separation by sparsifing its representations is exploited here to improve the performance of the state of the art sparse approximation algorithm "Iterative Soft Thresholding" (IST by adding new algorithmic features inspired by the DG circuitry. Lateral inhibition of granule cells, either direct or indirect, via mossy cells, is shown to enhance the performance of the IST. Apart from revealing the potential of DG-inspired theoretical algorithms, this work presents new insights regarding the function of particular cell types in the pattern separation task of the DG.

    Art is a characteristic of mankind, which requires superior central nervous processing and integration of motor functions with visual information. At the present time, a significant amount of information related to neurobiological basis of artistic creation has been derived from neuro-radiological cognitive studies, which have revealed that subsequent to tissue destruction, the artists continue to create art. The current study aims to review the most important cases of visual artists with stroke and to discuss artistic skills recovery and compensation as well as artistic style after stroke. The role of various central nervous system regions in artistic creation was reviewed on the basis of previously published functional studies. Our PubMed search (1995-2015) has identified 10 famous artists with right cerebral stroke as well as 5 with left cerebral stroke who survived and continued to create art after stroke. As the artists included in this review lived at various times during the twentieth century and in different countries, clinical information related to their case was limited. However, it appears that artistic skills recovery and compensation appear within days after stroke. Some of the artists would subsequently change their artistic style. All these elements have been evaluated within the context of specific clinical cases. The poststroke artistic skills recovery and compensation with development of a new style or the opposite, regaining the previous prestroke style, represents a significant element of clinical importance in medical rehabilitation as well as neuroesthetics, which requires further evaluation. At the present time, the molecular mechanisms of artistic creation are poorly understood, and more standardized clinical and experimental studies are needed.

    1977-01-01

    An artist active drawing and waterpainting, most prominent in sculpture, suffered an apopleptic insult at 66 years of age. Right hemiparesis and severe motor aphasia remained but this with rare unexpected and sometimes rather complicated productions in spoken, and also in written language in spite of modest progress in writing exercise. His behaviour witnessed of the memory of remote and complicated stored material. Some months after the insult he resumed his artistic activity using his left hand and continued it principally in the same manner as before his illness. His drawing and water-painting displayed some uncertainty of lines and sometimes coarseness of the stain spots. His pieces of sculpture regained the quality of his earlier works, as proven already by the first statue he made after the insult. While it is generally accepted that the motor aphasia does not essentially affect the artistic production, even of high quality, in painting, this is the first instance which proves that the same holds true for sculpture. In this case the mechanisms inciting the finest innervation on the side of the cortical center of the left hand, can work with promptness. In motor aphasia the mechanisms indispensable for the correct realisation of the function are affected without a final extinction of the function itself. Motor asphasia is an instrumental disorder not necessarily accompanied by disturbances of the intelligence.

    The analysis of road network designs can provide useful information to transportation planners as they seek to improve the safety of road networks. The objectives of this study were to compare and define the effective road network indices and to analyze the relationship between road network structure and traffic safety at the level of the Traffic Analysis Zone (TAZ). One problem in comparing different road networks is establishing criteria that can be used to scale networks in terms of their structures. Based on data from Orange and Hillsborough Counties in Florida, road network structural properties within TAZs were scaled using 3 indices: Closeness Centrality, Betweenness Centrality, and Meshedness Coefficient. The Meshedness Coefficient performed best in capturing the structural features of the road network. Bayesian Conditional Autoregressive (CAR) models were developed to assess the safety of various network configurations as measured by total crashes, crashes on state roads, and crashes on local roads. The models' results showed that crash frequencies on local roads were closely related to factors within the TAZs (e.g., zonal network structure, TAZ population), while crash frequencies on state roads were closely related to the road and traffic features of state roads. For the safety effects of different networks, the Grid type was associated with the highest frequency of crashes, followed by the Mixed type, the Loops & Lollipops type, and the Sparse type. This study shows that it is possible to develop a quantitative scale for structural properties of a road network, and to use that scale to calculate the relationships between network structural properties and safety.

    Cecile Massart is a visual artist who lives and works in Brussels, Belgium. Her teaching career includes Academy of Ixelles, Ecole Superieure des Arts Plastiques et Visuels in Mons, and Ecole Nationale Superieure des Arts Visuels La Cambre in Brussels. Cecile Massart has presented her extensive artistic research at numerous international conferences. Her works are featured in private and public collections. Since 1994, Cecile Massart has been investigating international sites for radioactive waste storage, exploring how this 21. century archaeological stratum is being inscribed in the landscape. Researching radioactive waste sites around the world for over 20 years, her main focus has become their identification in the landscape. Her ideas are communicated through her visual research and writings that aim to raise the awareness of radioactive disposal sites and to study their life within their surroundings for future generations. Her drawings, films, books and exhibitions investigate a new kind of architecture of the sites that become research platforms. Her first graphic research, edited under the title Un site archive pour Alpha, Beta, Gamma, helps in revealing their true nature. Her photographs, silk-screen prints, installations and pictures testify to the need to preserve the memory and knowledge of such sites across generations ensuring the safety of the living world. With this objective in mind, to build a memory, she has developed an architectural vocabulary functioning as warning sculptures to identify the nuclear repositories in the landscape: markers or archi-sculptures. In the following sections, Cecile Massart describes her work in her own words. For more details on her work, see www.cecilemassart.com

    Geoffrey Miller has hypothesized that producing artwork functions as a mating display. Here we investigate the relationship between mating success and artistic success in a sample of 236 visual artists. Initially, we derived a measure of artistic success that covered a broad range of artistic behaviors and beliefs. As predicted by Miller’s evolutionary theory, more successful male artists had more sexual partners than less successful artists but this did not hold for female artists. Also, male artists with greater artistic success had a mating strategy based on longer term relationships. Overall the results provide partial support for the sexual selection hypothesis for the function of visual art. PMID:22059085

    Despite a more prominent role of arts education in the school curriculum, artistic creativity does not occur to a great extent in primary school practice. More opportunities for teachers to strengthen their know-how in the field of artistic creativity can therefore be considered important. Arts education projects focus on pupils' development of…

    Bullot & Reber (B&R) correctly include historical perspectives into the scientific study of art appreciation. But artistic understanding always emerges from embodied simulation processes that incorporate the ongoing dynamics of brains, bodies, and world interactions. There may not be separate modes of artistic understanding, but a continuum of processes that provide imaginative simulations of the artworks we see or hear.

  18. Alien Sunset (Artist Concept)

    Science.gov (United States)

    2007-01-01

    Our solitary sunsets here on Earth might not be all that common in the grand scheme of things. New observations from NASA's Spitzer Space Telescope have revealed that mature planetary systems -- dusty disks of asteroids, comets and possibly planets -- are more frequent around close-knit twin, or binary, stars than single stars like our sun. That means sunsets like the one portrayed in this artist's photo concept, and more famously in the movie 'Star Wars,' might be quite commonplace in the universe. Binary and multiple-star systems are about twice as abundant as single-star systems in our galaxy, and, in theory, other galaxies. In a typical binary system, two stars of roughly similar masses twirl around each other like pair-figure skaters. In some systems, the two stars are very far apart and barely interact with each other. In other cases, the stellar twins are intricately linked, whipping around each other quickly due to the force of gravity. Astronomers have discovered dozens of planets that orbit around a single member of a very wide stellar duo. Sunsets from these worlds would look like our own, and the second sun would just look like a bright star in the night sky. But do planets exist in the tighter systems, where two suns would dip below a planet's horizon one by one? Unveiling planets in these systems is tricky, so astronomers used Spitzer to look for disks of swirling planetary debris instead. These disks are made of asteroids, comets and possibly planets. The rocky material in them bangs together and kicks up dust that Spitzer's infrared eyes can see. Our own solar system is swaddled in a similar type of disk. Surprisingly, Spitzer found more debris disks around the tightest binaries it studied (about 20 stars) than in a comparable sample of single stars. About 60 percent of the tight binaries had disks, while the single stars only had about 20 percent. These snug binary systems are as close or closer than just three times the distance between Earth and

    To achieve this goal, defamiliarization has been used as a criterion for recognizing the artistic aspects of mystical texts. Therefore, by giving a general review of literary theories of 20th century, defamiliarization and foregrounding have been considered in the works of Formalists and Structuralists. In this framework, the function of some of the features of mystical thought such as symbol and interpretation, revelation, relativism, repeated creation and wonder (Hayrat in artistic creation have been investigated. These features produce a multilayered insight in authors of mystical texts. The results of such insight can be seen in the language of these texts. In this language, defamiliarized features produce an artistic perception in the readers of the texts.

    Soon after you begin studying the sky through your small telescope or binoculars, you will probably be encouraged by others to make sketches of what you see. Sketching is a time-honored tradition in amateur astronomy and dates back to the earliest times, when telescopes were invented. Even though we have lots of new imaging technologies nowadays, including astrophotography, most observers still use sketching to keep a record of what they see, make them better observers, and in hopes of perhaps contributing something to the body of scientific knowledge about the Moon. Some even sketch because it satisfies their artistic side. The Moon presents some unique challenges to the astronomer-artist, the Moon being so fond of tricks of the light. Sketching the Moon: An Astronomical Artist’s Guide, by five of the best lunar observer-artists working today, will guide you along your way and help you to achieve really high-quality sketches. All the major types of lunar features are covered, with a variety of sketching te...

    A comprehensive understanding of both the chemical composition and physical behaviour of modern materials is an important consideration in devising correct conservation treatments for contemporary artworks. To this end, national and international research projects and networks have been established that deal mainly with the preservation, conservation, and understanding of materials used by contemporary artists. This paper focuses on the self-taught artist Fernando Melani (1907-1985), one of the precursors of the Poor Art artistic movement in Italy, and for the first time provides a scientific viewpoint on the artist's materials and works. The analyses, which mainly focus on the pigments/dyes found in his home-studio, were carried out primarily by using Fourier Transform Infrared Spectroscopy (FT-IR) and ultraviolet, visible, and near-infrared Fibre Optic Reflectance Spectroscopy (UV-Vis-NIR FORS). This paper emphasises the performance of FT-IR and FORS in the identification of contemporary artistic materials, since these two techniques have been found to produce highly complementary data. The use of both of these was required in order to obtain a comprehensive understanding of the composition of Melani's materials. Furthermore, one of his artworks, named by Melani himself with its inventory number N. Inv. 2625 (1981), was investigated in situ with the sole use of the FORS technique. The results showed that Melani used traditional inorganic pigments as well as modern organic dyes. Calcite and barite were used as fillers and extenders. Sulphur and abrasive powder were also found, thus confirming his use of a large variety of non-conventional artists' materials.

    Some features of fuel behavior at high fuel burnups, in particular, initiation and development of rim-layer, increase in the rate of fission gas release from the fuel and increase in the inner gas pressure in the fuel rod are briefly described. Basing on the analysis of the data of post-irradiation examinations of fuel rods of WWER-440 working FA and CR fuel followers, that have been operated for five fuel cycles and got the average fuel burnup or varies as 50MW-day/kgU, a conclusion is made that the WWER-440 fuel burnup can be increased at least to average burnups of 55-58 MW-day/kgU per fuel assembly (Authors)

  6. How is the artist role affected when artists are participating in projects in work life?

    Science.gov (United States)

    Stenberg, Henrik

    2016-01-01

    In Sweden, during the last decade, the artist has come to function as a creative resource in workplaces. There are two organisations, Skiss (Contemporary Artist in the Contemporary Society) and Airis (Artist in Residence), that organise projects for artists and coworkers. These projects are intended to have a positive effect on the well-being of organisations and their employees through artistic means, and the artist often focuses on the social interaction between the employees in their work. The artists' work involves frequent interaction with coworkers. The aim of this article was to describe how visual artists' roles as artists are affected by their engagement in artistic and social projects at workplaces in Sweden. The focus in the article is on the social interaction between artists and employees. The study is a qualitative narrative interview study with fine artists participating in different projects in work life. Since the artist's intervention is usually directed towards social relations in the workplaces, a social perspective on well-being is from a micro-sociological point of view. The categories in the interviews were how the artists worked with the projects, how the social interaction between artists and coworkers worked out, and how the artists evaluated the projects in relation to their ambitions. The results show that, many times, the artistic projects promote well-being in organisations and to some extent benefit the artist, but that the ability of the artists to actually function as artists can be problematic.

    Full Text Available Teacher evaluation represents a nodal aspect for improving of system education. Any evaluation has a previously predefined purpose and is essentially a valorative act, where the principles applied are indicators of the degree of responsibility which is performed and the visión that society gives to the education. This paper analyzes how the purposes are fulfilled, principles and characteristics of the performance evaluation of teachers in connection with the practice of respect for the guiding principles of assessment practice teaching; just like existing rating on indicators of professional and personal development achieved by teachers as a result of the evaluative practices in the context of the pursuit of improving of quality of education.

Conditions for specific risk monitoring are also presented.The notion of fail-safe feature of aircraft functional systems is analysed, and the necessity of continuous process of safety flight level estimate is shown. The method of quantitative assessment of key events and risks probabilities with the use of modern software is proposed. This method contains 5 basic stages: The monitoring parameters setting - this stage is initial and begins with the consideration of organization safety cul- ture, the main purposes and problems determination, the basic parameters and characteristics forming which are to be monitored. The event monitoring in operation - on this stage continuous process of key events searching and monitoring which are a thing of importance within the framework of the established problems takes place. This process is closely relat- ed to parameters monitoring set on the first stage. The event and risk estimate - this stage begins directly after the event has been discovered. The estimate pro- cess is as long as it is required to identify the event gravity. It also contains the preliminary risk estimate for using in priori- tization of initial expanded estimate and in the working out of plan for activities realization. The working out of plan for activities - on this stage correction data is determined that will make changes to aero- technics working out, operation, maintenance and to staff training directly in linkage to the problem event identified earlier. The activity carrying-out - the realization of actions according to the activity plan. This stage concludes priori- tization, planning and problem carrying-out. The dependence set between the probability of failure situations and the degree of their danger is shown.

    The bar PANDA experiment at FAIR will use DIRC detectors for the separation of hadrons. The compactness of the bar PANDA detector requires the image planes of these detectors to be placed inside the magnetic field of the solenoid. Due to this and other boundary conditions MCP-PMTs were identified as the only suitable photon sensors. Until recently the major obstacle for an application of MCP-PMTs in high rate experiments like bar PANDA were serious aging problems which led to damage at the photo-cathode and a fast declining quantum efficiency as the integrated anode charge (IAC) increased. With new countermeasures against the aging, in particular due to the application of an atomic layer deposition (ALD) technique to coat the MCP pores, the lifetime of MCP-PMTs has meanwhile increased by a factor >50 which is fully sufficient for bar PANDA. The recent results of our long-term lifetime measurements are discussed. New 2-inch MCP-PMT prototypes from Hamamatsu show an encouraging behavior. However, the currently best performing MCP-PMT is a 2-inch PHOTONIS tube with two ALD-layers which reaches an IAC of >16 C/cm2 without any visible sign of aging. In the second part of these proceedings a new data acquisition system of the PADIWA/TRB type is presented which allows a quasi-parallel measurement of many MCP-PMT performance parameters. Especially unwanted effects like dark-count rate, crosstalk, ion after-pulsing, and recoil electrons can be studied in more detail than ever before. Exemplary results for these parameters are shown. The discussed DAQ system will be used for the comprehensive data quality checks of the MCP-PMTs being built into the DIRCs.

    Since 1994, the French National Agency for Radioactive Waste Management (Andra) has been pursuing a study of collective memory, based on its experience with the Manche disposal facility. In 2010 - in response to the project Centre industriel de stockage geologique (Cigeo), its concomitant need to preserve collective memory of the site for at least 500 years, and public demand - Andra launched an initiative to ensure that future generations do not forget about the existence of radioactive waste disposal facilities. Pursuing its investigations in this area, Andra has led theoretical enquiries that consider art as a possible vehicle of collective memory. Memory is often found between parentheses that do not overload the spirit but enclose it in rules that facilitate forgetting... which is a vanity of the present moment. The past must always have the role of providing future ferment. And then the transfer occurs that can open up to history. Born in 1938, Gerard Larguier began working in 1956 with the renowned poster artist Paul Colin of Nancy before going on to study at the Beaux-Arts in Paris and Academie Julian. He has worked at his studio in the Bateau Lavoir in Paris since 1979 as well as Bonnet's former presbytery in the Meuse since 1973. Using both materials and relief, he has exhibited his artwork at leading institutions around the world. Since 1998, he has taken up the theme of memory in his works 'Chronique du XXeme siecle', 'Autodafes et palimpsestes' and his series 'A saute-souvenances'. He has also tackled the evolution of artwork over the centuries in a series of fifty works entitled 'Les chefs-d'oeuvre revisites'. In 2008, Gerard Larguier completed a fresco commissioned by Andra on the local heritage and environment of the Bure Laboratory. In 2010, the municipality of Soulaines d'Huys commissioned a fresco of the history of the town from the sixteenth century to the present using the archives of

    Medical Data mining is the search for relationships and patterns within the medical datasets that could provide useful knowledge for effective clinical decisions. The inclusion of irrelevant, redundant and noisy features in the process model results in poor predictive accuracy. Much research work in data mining has gone into improving the predictive accuracy of the classifiers by applying the techniques of feature selection. Feature selection in medical data mining is appreciable as the diagnosis of the disease could be done in this patient-care activity with minimum number of significant features. The objective of this work is to show that selecting the more significant features would improve the performance of the classifier. We empirically evaluate the classification effectiveness of LibSVM classifier on the reduced feature subset of diabetes dataset. The evaluations suggest that the feature subset selected improves the predictive accuracy of the classifier and reduce false negatives and false positives.

    Feature detection and matching are key techniques in computer vision and robotics, and have been successfully implemented in many fields. So far there is no performance comparison of feature detectors and matching methods for planetary mapping and rover localization using rover stereo images. In this research, we present a comprehensive evaluation and comparison of six feature detectors, including Moravec, Förstner, Harris, FAST, SIFT and SURF, aiming for optimal implementation of feature-based matching in planetary surface environment. To facilitate quantitative analysis, a series of evaluation criteria, including distribution evenness of matched points, coverage of detected points, and feature matching accuracy, are developed in the research. In order to perform exhaustive evaluation, stereo images, simulated under different baseline, pitch angle, and interval of adjacent rover locations, are taken as experimental data source. The comparison results show that SIFT offers the best overall performance, especially it is less sensitive to changes of image taken at adjacent locations.

    An artist-led exploration of portrait accuracy and likeness involved 12 Artists producing 12 portraits referencing a life-size 3D print of the same Sitter. The works were assessed during a public exhibition, and the resulting likeness assessments were compared to portrait accuracy as measured using geometric morphometrics (statistical shape analysis). Our results are that, independently of the assessors' prior familiarity with the Sitter's face, the likeness judgements tended to be higher for less morphologically accurate portraits. The two highest rated were the portrait that most exaggerated the Sitter's distinctive features, and a portrait that was a more accurate (but not the most accurate) depiction. In keeping with research showing photograph likeness assessments involve recognition, we found familiar assessors rated the two highest ranked portraits even higher than those with some or no familiarity. In contrast, those lacking prior familiarity with the Sitter's face showed greater favour for the portrait with the highest morphological accuracy, and therefore most likely engaged in face-matching with the exhibited 3D print. Furthermore, our research indicates that abstraction in portraiture may not enhance likeness, and we found that when our 12 highly diverse portraits were statistically averaged, this resulted in a portrait that is more morphologically accurate than any of the individual artworks comprising the average.

    The reflection of medicine in the universal arts has motivated several rheumatologists to discover features of rheumatic diseases depicted by the artist's eyes long before they were defined as specific pathologic entities. The result has been the identification of several pieces of art dating from the Middle Ages, the Renaissance, the Baroque and Post-Impressionist periods that depict clear features of several rheumatic diseases such as RA, OA, camptodactyly and temporal arteritis, among others. On the other hand, great artists such as Pierre-Auguste Renoir, Antoni Gaudí, Raoul Dufy, Paul Klee, Frida Kahlo and Niki de Saint Phalle are good examples of how rheumatic diseases such as RA, scleroderma and chronic pain can influence the artist's perspective, the technique used and the content of their work. Art can serve as a powerful resource to understand the natural course of diseases. By learning through the artist's eyes the way illnesses behave and evolve in time, rheumatologists can trace the history of several conditions. © The Author 2014.

  10. Robustness of digital artist authentication

    DEFF Research Database (Denmark)

    Jacobsen, Robert; Nielsen, Morten

    In many cases it is possible to determine the authenticity of a painting from digital reproductions of the paintings; this has been demonstrated for a variety of artists and with different approaches. Common to all these methods in digital artist authentication is that the potential of the method...... is in focus, while the robustness has not been considered, i.e. the degree to which the data collection process influences the decision of the method. However, in order for an authentication method to be successful in practice, it needs to be robust to plausible error sources from the data collection....... In this paper we investigate the robustness of the newly proposed authenticity method introduced by the authors based on second generation multiresolution analysis. This is done by modelling a number of realistic factors that can occur in the data collection....

  13. Artistic production in dyslectic children.

    1977-01-01

    In the study of children with language problems, particularly in reading and writing, it has been observed that some have an outstanding ability to produce artistic pictures and objects. These productions are perceptive, well organized and generally contain much action. Despite their pictorial skill these patients may have only a rudimentary use of coded symbolic graphic forms. Others display moderate ability in reading and writing. These patients frequently have the disorganized overacctive behavior and the motor clumsiness that is so common in the dyslectic child; some, however, are biologically effective. From this material we entertain the hypothesis that picture (artistic) productions are generated by the sub-dominant cerebral hemisphere, and that this function is quite distinct from the coded graphic operations resident in the dominant hemisphere. If this hypothesis is correct, it would seem socially benefical to allow these patients to develop their unique artistic ability to its full capacity, and not to overemphasize the correction of the disturbed coded symbol operations in remedial training.

    Full Text Available Art as process and reflection of the lived moment deals many times with issues that refers to its context and with the available materials in the current scenario. In a society marked by consumption and ephemerality, this article promotes a reflection on the use of disposed and collected products in works of visual artists. The bricoleur appears in this context as a central figure for the understanding and the analysis of some of the many artistic practices realized recently. By bricolage, artists like Joseph Cornell, Farnese de Andrade, Amanda Mei and Courtney Smith performed works with hybrid content that reflect the lived moment and issues contained in the materials available in the current scenario.

    Lise Hovik

    2012-11-01

    Full Text Available The author discusses different approaches to artistic research based on her own research project involving several closely related theatre performances for young children. Key to the project is the development of a form of dance theatre in which the child audience is given the opportunity to actively participate and interact with the performers. The dramatic structure of the improvised dance concert Mamma Danser (2011 alternates between a common focus, an individual, “own” focus and a “multifocus”. The article discusses what implications this may have for the children, the performers and the researching artist. In scientific research a clear focus and a reflective perspective are often seen as crucial for the result, while in artistic processes more intuitive and improvised approaches are employed, consequently providing a different type of knowledge. Such knowledge, which is not readily accessible through the “outsider" perspective of hermeneutic interpretation, becomes evident by setting different interpretations and perspectives in dialogue with each other and with the performers’ own bodily experiences. Henk Borgdorff’s separation between an interpretive, an instrumental, and a performative research perspective is applied to provide a comprehensive picture of the process of creating artistic performances for young children. In conclusion, the author maintains that this research project demonstrates the possibility of creating common art experiences in which both adults and children take part in reciprocal interaction and improvisation.

    2016-10-01

    Despite object detection, recognition, and identification being very active areas of computer vision research, many of the available tools to aid in these processes are designed with only photographs in mind. Although some algorithms used specifically for feature detection and identification may not take explicit advantage of the colors available in the image, they still under-perform on radiographs, which are grayscale images. We are especially interested in the robustness of these algorithms, specifically their performance on a preexisting database of X-ray radiographs in compressed JPEG form, with multiple ways of describing pixel information. We will review various aspects of the performance of available feature detection and identification systems, including MATLABs Computer Vision toolbox, VLFeat, and OpenCV on our non-ideal database. In the process, we will explore possible reasons for the algorithms' lessened ability to detect and identify features from the X-ray radiographs.

  20. Replicating distinctive facial features in lineups: identification performance in young versus older adults.

    2013-04-01

    Criminal suspects with distinctive facial features, such as tattoos or bruising, may stand out in a police lineup. To prevent suspects from being unfairly identified on the basis of their distinctive feature, the police often manipulate lineup images to ensure that all of the members appear similar. Recent research shows that replicating a distinctive feature across lineup members enhances eyewitness identification performance, relative to removing that feature on the target. In line with this finding, the present study demonstrated that with young adults (n = 60; mean age = 20), replication resulted in more target identifications than did removal in target-present lineups and that replication did not impair performance, relative to removal, in target-absent lineups. Older adults (n = 90; mean age = 74) performed significantly worse than young adults, identifying fewer targets and more foils; moreover, older adults showed a minimal benefit from replication over removal. This pattern is consistent with the associative deficit hypothesis of aging, such that older adults form weaker links between faces and their distinctive features. Although replication did not produce much benefit over removal for older adults, it was not detrimental to their performance. Therefore, the results suggest that replication may not be as beneficial to older adults as it is to young adults and demonstrate a new practical implication of age-related associative deficits in memory.

    2011-09-01

    Full Text Available Indonesia’s leading mime artist, Jemek Supardi, is a former pickpocket and grave-digger. Based in the key centre of Indonesian performative arts, the city of Yogyakarta, Central Java, Jemek is an active member of several artistic troupes and he is a collaborator, friend and acquaintance of many within the closely-knit arts-scene, which in terms of diversity and sheer volume of performances, is unique in Indonesia. Although mime is a niche art-form in Indonesia, Jemek’s self-taught skill as a pantomime artist is clearly evident and his reputation as a professional is second-to-none, particularly in Yogyakarta. This article examines key elements of Jemek’s performative milieu, including his use of mime and silence as a mode of cultural and political expression and his use of white face-paint as an expression of solidarity with the Javanese proletariat. The link between the personal and political elements of Jemek’s artistic practice will also be examined, simultaneously highlighting the difficulty of applying any particular theoretical template onto his life and art.

    Higher recall rates are a major challenge in mammography screening. Thus, developing computer-aided diagnosis (CAD) scheme to classify between malignant and benign breast lesions can play an important role to improve efficacy of mammography screening. Objective of this study is to develop and test a unique image feature fusion framework to improve performance in classifying suspicious mass-like breast lesions depicting on mammograms. The image dataset consists of 302 suspicious masses detected on both craniocaudal and mediolateral-oblique view images. Amongst them, 151 were malignant and 151 were benign. The study consists of following 3 image processing and feature analysis steps. First, an adaptive region growing segmentation algorithm was used to automatically segment mass regions. Second, a set of 70 image features related to spatial and frequency characteristics of mass regions were initially computed. Third, a generalized linear regression model (GLM) based machine learning classifier combined with a bat optimization algorithm was used to optimally fuse the selected image features based on predefined assessment performance index. An area under ROC curve (AUC) with was used as a performance assessment index. Applying CAD scheme to the testing dataset, AUC was 0.75+/-0.04, which was significantly higher than using a single best feature (AUC=0.69+/-0.05) or the classifier with equally weighted features (AUC=0.73+/-0.05). This study demonstrated that comparing to the conventional equal-weighted approach, using an unequal-weighted feature fusion approach had potential to significantly improve accuracy in classifying between malignant and benign breast masses.

  8. Effect of dominant features on neural network performance in the classification of mammographic lesions

    Two different classifiers, an artificial neural network (Ann) and a hybrid system (one step rule-based method followed by an artificial neural network) have been investigated to merge computer-extracted features in the task of differentiating between malignant and benign masses. A database consisting of 65 cases (38 malignant and 26 benign) was used in the study. A total of four computer-extracted features - spiculation, margin sharpness and two density-related measures - was used to characterize these masses. Results from our previous study showed that the hybrid system performed better than the ANN classifier. In our current study, to understand the difference between the two classifiers, we investigated their learning and decision-making processes by studying the relationships between the input features and the outputs. A correlation study showed that the outputs from the ANN-alone method correlated strongly with one of the input features (spiculation), yielding a correlation coefficient of 0.91, whereas the correlation coefficients (absolute value) for the other features ranged from 0.19 to 0.40. This strong correlation between the ANN output and spiculation measure indicates that the learning and decision-making processes of the ANN-alone method were dominated by the spiculation measure. Three-dimensional plots of the computer output as functions of the input features demonstrate that the ANN-alone method did not learn as effectively as the hybrid system in differentiating non-spiculated malignant masses from benign masses, thus resulting in an inferior performance at the high sensitivity levels. We found that with a limited database it is detrimental for an ANN to learn the significance of other features in the presence of a dominant feature. The hybrid system, which initially applied a rule concerning the value of the spiculation measure prior to employing an ANN, prevents over-learning from the dominant feature and performed better than the ANN-alone method

    2017-07-01

    This paper examines the accuracy and efficiency (time complexity) of high performance genetic data feature selection and classification algorithms for colon cancer diagnosis. The need for this research derives from the urgent and increasing need for accurate and efficient algorithms. Colon cancer is a leading cause of death worldwide, hence it is vitally important for the cancer tissues to be expertly identified and classified in a rapid and timely manner, to assure both a fast detection of the disease and to expedite the drug discovery process. In this research, a three-phase approach was proposed and implemented: Phases One and Two examined the feature selection algorithms and classification algorithms employed separately, and Phase Three examined the performance of the combination of these. It was found from Phase One that the Particle Swarm Optimization (PSO) algorithm performed best with the colon dataset as a feature selection (29 genes selected) and from Phase Two that the Support Vector Machine (SVM) algorithm outperformed other classifications, with an accuracy of almost 86%. It was also found from Phase Three that the combined use of PSO and SVM surpassed other algorithms in accuracy and performance, and was faster in terms of time analysis (94%). It is concluded that applying feature selection algorithms prior to classification algorithms results in better accuracy than when the latter are applied alone. This conclusion is important and significant to industry and society. Copyright © 2017 Elsevier B.V. All rights reserved.

  15. Bearing performance degradation assessment based on time-frequency code features and SOM network

    International Nuclear Information System (INIS)

    Zhang, Yan; Tang, Baoping; Han, Yan; Deng, Lei

    2017-01-01

    Bearing performance degradation assessment and prognostics are extremely important in supporting maintenance decision and guaranteeing the system’s reliability. To achieve this goal, this paper proposes a novel feature extraction method for the degradation assessment and prognostics of bearings. Features of time-frequency codes (TFCs) are extracted from the time-frequency distribution using a hybrid procedure based on short-time Fourier transform (STFT) and non-negative matrix factorization (NMF) theory. An alternative way to design the health indicator is investigated by quantifying the similarity between feature vectors using a self-organizing map (SOM) network. On the basis of this idea, a new health indicator called time-frequency code quantification error (TFCQE) is proposed to assess the performance degradation of the bearing. This indicator is constructed based on the bearing real-time behavior and the SOM model that is previously trained with only the TFC vectors under the normal condition. Vibration signals collected from the bearing run-to-failure tests are used to validate the developed method. The comparison results demonstrate the superiority of the proposed TFCQE indicator over many other traditional features in terms of feature quality metrics, incipient degradation identification and achieving accurate prediction. Highlights • Time-frequency codes are extracted to reflect the signals’ characteristics. • SOM network served as a tool to quantify the similarity between feature vectors. • A new health indicator is proposed to demonstrate the whole stage of degradation development. • The method is useful for extracting the degradation features and detecting the incipient degradation. • The superiority of the proposed method is verified using experimental data.

    Minor geometric features and imperfections are commonly introduced into the basic design of multi-component systems to simplify or reduce the manufacturing expense. In this work, the cooling performance of a Stirling type cryocooler was tested in different driving powers, cold-end temperatures and inclination angles. A series of Computational Fluid Dynamics (CFD) simulations based on a prototypical cold tip was carried out. Detailed CFD model predictions were compared with the experiment and were used to investigate the impact of such apparently minor geometric imperfections on the performance of Stirling type pulse tube cryocoolers. Predictions of cooling performance and gravity orientation sensitivity were compared with experimental results obtained with the cryocooler prototypes. The results indicate that minor geometry features in the cold tip assembly can have considerable negative effects on the gravity orientation sensitivity of a pulse tube cryocooler.

    Aerosol Trapping In a Steam Generator (ARTIST) is a seven-phase international project (2003-2007) which investigates aerosol and droplet retention in a model steam generator under dry, wet and accident management conditions, respectively. The test section is comprised of a scaled steam generator tube bundle consisting of 270 tubes and three stages, one 1:1 separator unit, and one 1:1 dryer unit. As a prelude to the ARTIST project, four tests are conducted in the ARTIST bundle within the 5th EU FWP SGTR. These first tests address aerosol deposition phenomena on two different scales: near the tube break, where the gas velocities are sonic, and far away from the break, where the flow velocities are three orders of magnitude lower. With a dry bundle and the full flow representing the break stage conditions, there is strong evidence that the TiO 2 aerosols used (AMMD 2-4 μm, 32 nm primary particles) disintegrate into much smaller particles because of the sonic conditions at the break, hence promoting particle escape from the secondary and lowering the overall DF, which is found to be between 2.5 and 3. With a dry bundle and a small flow reproducing the far-field velocities, the overall bundle DF is of the order of 5, implying a DF of about 1.9 per stage. Extrapolating the results of the dry tests, it turns out that for steam generators with nine or more stages, it is expected that substantial DF's could be achieved when the break is located near the tube sheet region. In addition, better decontamination is expected using more representative proxies of severe accident aerosols (sticky, multi-component particles), a topic which is yet to be investigated. When the bundle is flooded, the DF is between 45 and 5740, depending on the mass flow rate, the steam content, and the water submergence. The presence of steam in the carrier gas and subsequent condensation inside the broken tube causes aerosol deposition and blockages near the break, leading to an increase in the

    ARTIST (Aerosol Trapping In a Steam Generator) is an international project which investigates aerosol and droplet retention in a model steam generator under dry, wet and accident management conditions, respectively. The test section comprises a scaled steam generator tube bundle consisting of 270 tubes and 3 stages, one 1:1 separator unit, and one 1:1 dryer unit. As a prelude to the ARTIST project, four tests are conducted in the ARTIST bundle. These first tests address aerosol deposition phenomena on two different scales: near the tube break, where the gas velocities are sonic, and far away from the break, where the flow velocities are 3 orders of magnitude lower. With a dry bundle and the full flow representing the break stage conditions, there is strong evidence that the TiO 2 aerosols used (AMMD 2-4 μm, 32 nm primary particles) disintegrate into much smaller particles because of the sonic conditions at the break, hence promoting particle escape from the secondary and lowering the overall decontamination factor (DF), which is found to be between 2.5 and 3. With a dry bundle and a small flow reproducing the far-field velocities, the overall bundle DF is of the order of 5, implying a DF of about 1.9 per stage. Extrapolating the results of the dry tests, it turns out that for steam generators with 9 or more stages, it is expected that substantial DFs could be achieved when the break is located near the tube sheet region. In addition, better decontamination is expected using more representative proxies of severe accident aerosols (sticky, multicomponent particles), a topic which is yet to be investigated. When the bundle is flooded, the DF is between 45 and 5740, depending on the mass flow rate, the steam content, and the water submergence. The presence of steam in the carrier gas and subsequent condensation inside the broken tube causes aerosol deposition and blockages near the break, leading to an increase in the primary pressure. This has implications for real

    Research with younger adults has shown that retrospective cues can be used to orient top-down attention toward relevant items in working memory. We examined whether older adults could take advantage of these cues to improve memory performance. Younger and older adults were presented with visual arrays of five colored shapes; during maintenance, participants were presented either with an informative cue based on an object feature (here, object shape or color) that would be probed, or with an uninformative, neutral cue. Although older adults were less accurate overall, both age groups benefited from the presentation of an informative, feature-based cue relative to a neutral cue. Surprisingly, we also observed differences in the effectiveness of shape versus color cues and their effects upon post-cue memory load. These results suggest that older adults can use top-down attention to remove irrelevant items from visual working memory, provided that task-relevant features function as cues.

    Marching artists are a unique group of athletes whose performance can be influenced by nutrition. Because physical demands are thought to be moderate to high, adequate energy and a variety of nutrient-dense foods are needed. The purpose of this study was to examine diet quality, physical activity, and eating behavior of marching artists across elite and nonelite competition levels. This cross-sectional analysis used the validated National Cancer Institute Diet History Questionnaire II, International Physical Activity Questionnaire, and Eating Behavior Patterns Questionnaire. Diet quality was assessed using the Healthy Eating Index (HEI) 2010. Marching artists who participated in marching band in 2015 were eligible. Those in Drum Corps International (DCI) were considered part of the elite level; all others were considered nonelite. Chi-square analyses assessed associations between categorical variables and competition level, and independent sample t-tests assessed differences between continuous variables among competition level. Participants (n = 323) included 228 (71%) DCI members and 95 (29%) non-DCI members who reported a mean age of 19.8 ± 1.9 years. DCI members reported higher physical activity levels (p competition levels. Only one participant overall (quality combined with high levels of physical activity is a problem for marching artists that should be addressed through carefully planned interventions.

  6. Artistic image analysis using graph-based learning approaches.

    2013-08-01

    We introduce a new methodology for the problem of artistic image analysis, which among other tasks, involves the automatic identification of visual classes present in an art work. In this paper, we advocate the idea that artistic image analysis must explore a graph that captures the network of artistic influences by computing the similarities in terms of appearance and manual annotation. One of the novelties of our methodology is the proposed formulation that is a principled way of combining these two similarities in a single graph. Using this graph, we show that an efficient random walk algorithm based on an inverted label propagation formulation produces more accurate annotation and retrieval results compared with the following baseline algorithms: bag of visual words, label propagation, matrix completion, and structural learning. We also show that the proposed approach leads to a more efficient inference and training procedures. This experiment is run on a database containing 988 artistic images (with 49 visual classification problems divided into a multiclass problem with 27 classes and 48 binary problems), where we show the inference and training running times, and quantitative comparisons with respect to several retrieval and annotation performance measures.

    The main objective of the Ph.D. study was to examine occupants’ perception of comfort and self-estimated job performance in non-industrial buildings (homes and offices), in particular how building occupants understand comfort and which parameters, not necessarily related to indoor environments...... and storage, noise level and visual privacy. However, if job performance is considered, then satisfaction with the main indoor environmental parameters should be addressed first as they affected self-estimated job performance to the highest extent. The present study showed that overall satisfaction...... with personal workspace affected significantly the self-estimated job performance. Increasing overall satisfaction with the personal workspace by about 15% would correspond to an increase of self-estimated job performance by 3.7%. Among indoor environmental parameters and building features, satisfaction...

    Web proxy cache technique reduces response time by storing a copy of pages between client and server sides. If requested pages are cached in the proxy, there is no need to access the server. Due to the limited size and excessive cost of cache compared to the other storages, cache replacement algorithm is used to determine evict page when the cache is full. On the other hand, the conventional algorithms for replacement such as Least Recently Use (LRU), First in First Out (FIFO), Least Frequently Use (LFU), Randomized Policy etc. may discard important pages just before use. Furthermore, using conventional algorithm cannot be well optimized since it requires some decision to intelligently evict a page before replacement. Hence, most researchers propose an integration among intelligent classifiers and replacement algorithm to improves replacement algorithms performance. This research proposes using automated wrapper feature selection methods to choose the best subset of features that are relevant and influence classifiers prediction accuracy. The result present that using wrapper feature selection methods namely: Best First (BFS), Incremental Wrapper subset selection(IWSS)embedded NB and particle swarm optimization(PSO)reduce number of features and have a good impact on reducing computation time. Using PSO enhance NB classifier accuracy by 1.1%, 0.43% and 0.22% over using NB with all features, using BFS and using IWSS embedded NB respectively. PSO rises J48 accuracy by 0.03%, 1.91 and 0.04% over using J48 classifier with all features, using IWSS-embedded NB and using BFS respectively. While using IWSS embedded NB fastest NB and J48 classifiers much more than BFS and PSO. However, it reduces computation time of NB by 0.1383 and reduce computation time of J48 by 2.998.

    Impairments in acoustically cued repetitive finger movement often emerge at rates near to and above 2Hz in persons with Parkinson's Disease (PD) in which some patients move faster (hastening) and others move slower (bradykinetic). The clinical features impacting this differential performance of repetitive finger movement remain unknown. The purpose of this study was to compare repetitive finger movement performance between the more and less affected side, and the difference in clinical ratings among performance groups. Forty-one participants diagnosed with idiopathic PD completed an acoustically cued repetitive finger movement task while "on" medication. Eighteen participants moved faster, 10 moved slower, and 13 were able to maintain the appropriate rate at rates above 2Hz. Clinical measures of laterality, disease severity, and the UPDRS were obtained. There were no significant differences between the more and less affected sides regardless of performance group. Comparison of disease severity, tremor, and rigidity among performance groups revealed no significant differences. Comparison of posture and postural instability scores revealed that the participants that demonstrated hastening had worse posture and postural instability scores. Consideration of movement rate during the clinical evaluation of repetitive finger movement may provide additional insight into varying disease features in persons with PD.

    Full Text Available Cognitive assessment in neurological diseases represents a relevant topic due to its diagnostic significance in detecting disease, but also in assessing progress of the treatment. Computer-based tests provide objective and accurate cognitive skills and capacity measures. The Ruff Figural Fluency Test (RFFT provides information about non-verbal capacity for initiation, planning, and divergent reasoning. The traditional paper form of the test was transformed into a computer application and examined. The RFFT was applied in an experiment performed among 70 male students to assess their cognitive performance in the laboratory environment. Each student was examined in three sequential series. Besides the students’ performances measured by using in app keylogging, the eye-tracking data obtained by non-invasive video-based oculography were gathered, from which several features were extracted. Eye-tracking features combined with performance measures (a total number of designs and/or error ratio were applied in machine learning classification. Various classification algorithms were applied, and their accuracy, specificity, sensitivity and performance were compared.

  15. Roles and significance of water conducting features for transport models in performance assessment

    International Nuclear Information System (INIS)

    Carrera, J.; Sanchez-Vila, X.; Medina, A.

    1999-01-01

    The term water conducting features (WCF) refers to zones of high hydraulic conductivity. In the context of waste disposal, it is further implied that they are narrow so that chances of sampling them are low. Yet, they may carry significant amounts of water. Moreover, their relatively small volumetric water content causes solutes to travel fast through them. Water-conducting features are a rather common feature of natural media. The fact that they have become a source of concern in recent years, reflects more the increased level of testing and monitoring than any intrinsic property of low permeability media. Accurate simulations of solute transport require a realistic accounting for water conducting features. Methods are presented to do so and examples are shown to illustrate these methods. Since detailed accounting of WCF's will not be possible in actual performance assessments, efforts should be directed towards typification, so as to identify the essential effects of WCF's on solute transport through different types of rocks. Field evidence suggests that, although individual WCF's may be difficult to characterize, their effects are quite predictable. (author)

  16. Face Recognition Performance Improvement using a Similarity Score of Feature Vectors based on Probabilistic Histograms

    SRIKOTE, G.

    2016-08-01

    Full Text Available This paper proposes an improved performance algorithm of face recognition to identify two face mismatch pairs in cases of incorrect decisions. The primary feature of this method is to deploy the similarity score with respect to Gaussian components between two previously unseen faces. Unlike the conventional classical vector distance measurement, our algorithms also consider the plot of summation of the similarity index versus face feature vector distance. A mixture of Gaussian models of labeled faces is also widely applicable to different biometric system parameters. By comparative evaluations, it has been shown that the efficiency of the proposed algorithm is superior to that of the conventional algorithm by an average accuracy of up to 1.15% and 16.87% when compared with 3x3 Multi-Region Histogram (MRH direct-bag-of-features and Principal Component Analysis (PCA-based face recognition systems, respectively. The experimental results show that similarity score consideration is more discriminative for face recognition compared to feature distance. Experimental results of Labeled Face in the Wild (LFW data set demonstrate that our algorithms are suitable for real applications probe-to-gallery identification of face recognition systems. Moreover, this proposed method can also be applied to other recognition systems and therefore additionally improves recognition scores.

    2003-06-01

    Attending any conference on visual perception undoubtedly leaves one exposed to the work of Salvador Dali, whose extended phase of work exploring what he dubbed, "the paranoiac-critical method" is very popular as examples of multiple perceptions from conflicting input. While all visual art is intertwined with perceptual science, from convincing three-dimensional illusion during the Renaissance to the isolated visual illusions of Bridget Riley"s Op-Art, direct statements about perception are rarely uttered by the artists in recent times. However, there are still a number of artists working today whose work contains perceptual questions and exemplars that can be of interest to vision scientists and imaging engineers. This talk will start sampling from Op-Art, which is most directly related to psychophysical test stimuli and then will discuss "perceptual installations" from artists such as James Turrell"s, whose focus is often directly on natural light, with no distortions imposed by any capture or display apparatus. His work generally involves installations that use daylight and focus the viewer on its nuanced qualities, such as umbra, air particle interactions, and effects of light adaptation. He is one of the last artists to actively discuss perception. Next we discuss minimal art and electronic art, with video artist Nam June Paik discussing the "intentionally boring" art of minimalism. Another artist using installations is Sandy Skoglund, who creates environments of constant spectral albedo, with the exception of her human occupants. Tom Shannon also uses installations as his media to delve into 3D aspects of depth and perspective, but in an atomized fashion. Beginning with installation concepts, Calvin Collum then adds the restrictive viewpoint of photography to create initially confusing images where the pictorial content and depth features are independent (analogous to the work of Patrick Hughes). Andy Goldsworthy also combines photography with concepts of

    Full Text Available Abstract In Artistic Gymnastics, the area (the apparatus represents the most relevant systemic component. Thus, when one strives to comprehend the internal logic of this sport, the gymnast-apparatus relationship warrants special attention. A change in the training paradigm was observed, showing that the use of Elastic Surfaces (ES is an essential resource, due to the contemporary features of this sport, such as the hyper-valorisation of acrobatics and a greater presence of flight elements. Through a case study developed in a men’s artistic gymnastics high-performance gymnasium, this study analysed the use of different ES in the training process. Although coaches recognize the importance of ES in training programs, the record of daily activities showed that this use is still limited to select equipment and is not systematic. Such difficulties are due mainly to the lack of educational programs to the development of certain specific methodologies and the non-existence of national equipment suppliers certified by International Gymnastics Federation.

  19. The evolution of human artistic creativity

    2010-01-01

    Creating visual art is one of the defining characteristics of the human species, but the paucity of archaeological evidence means that we have limited information on the origin and evolution of this aspect of human culture. The components of art include colour, pattern and the reproduction of visual likeness. The 2D and 3D art forms that were created by Upper Palaeolithic Europeans at least 30 000 years ago are conceptually equivalent to those created in recent centuries, indicating that human cognition and symbolling activity, as well as anatomy, were fully modern by that time. The origins of art are therefore much more ancient and lie within Africa, before worldwide human dispersal. The earliest known evidence of ‘artistic behaviour’ is of human body decoration, including skin colouring with ochre and the use of beads, although both may have had functional origins. Zig-zag and criss-cross patterns, nested curves and parallel lines are the earliest known patterns to have been created separately from the body; their similarity to entopic phenomena (involuntary products of the visual system) suggests a physiological origin. 3D art may have begun with human likeness recognition in natural objects, which were modified to enhance that likeness; some 2D art has also clearly been influenced by suggestive features of an uneven surface. The creation of images from the imagination, or ‘the mind’s eye’, required a seminal evolutionary change in the neural structures underpinning perception; this change would have had a survival advantage in both tool-making and hunting. Analysis of early tool-making techniques suggests that creating 3D objects (sculptures and reliefs) involves their cognitive deconstruction into a series of surfaces, a principle that could have been applied to early sculpture. The cognitive ability to create art separate from the body must have originated in Africa but the practice may have begun at different times in genetically and culturally

    Full Text Available In this paper the influence of information about high level features of Human Visual System (HVS on objective quality assessment is studied. This was done by extending the existing full-reference objective image quality metric – FSIM – where the different importance of certain areas of image is considered using Phase Congruency (PC algorithm. Here, the estimation of Region of Interest (ROI based on this algorithm is complemented by Fixation Density Maps (FDM containing the information about high level features of HVS. Use of another low level features based algorithm (Phase Spectrum of Fourier Transform was also considered and compared to the PC algorithm. The performance was evaluated qualitatively on images reconstructed according to ROI and quantitatively on images from LIVE database. The correlation between subjective and objective tests was calculated using Pearson’s Correlation Coefficient and Spearman’s Rank Order Coefficient. The statistical significance of the difference between correlation coefficients was assessed by Fisher r-to-z transformation. The performance of the metric was also compared to other state-of-the-art image quality metrics (SSIM, MS-SSIM, and FSIM.

    2017-10-01

    Full Text Available The article deals with the issue of theatricality – literariness in the artistic discourse, components that define the specificity of theatrical art and, at the same time, its synthetic essence. The relationship between the written dramatic text and the performance is manifested in the relationship between the representativeness, the theatricality of the dramaturgic text and its literary character as a writing. The concepts of theatricality as well as that of literariness as part of a dramaturgic discourse are presented from a diachronic perspective, emphasizing the relation between the writing and spectacular discourse on the level of structure and artistic form. At the same time, as forms of artistic communication and poetic, literary, theatrical, dramatic, etc. meet, “collaborate” not only in the dramaturgic discourse structure but also in the theatrical and the narrative ones, having different artistic functionalities. The elements of theatricality are realized in the dramaturgic or the epic text through a poetical specific to the creative individuality, his/her artistic vision. In a narrative discourse, theatricality can be understood as prediction, rules that shape the show from the text itself. The art of the realization of a narrative theatricality (in the relationship of digesis - mimesis in the epic text, through various artistic means and marks of theatricality, demonstrates not only the artistic thinking, the spectacular vision of the author, but also the topicality of the approach of the interference of arts in the scientific approach.

  2. AGSuite: Software to conduct feature analysis of artificial grammar learning performance.

    2017-10-01

    To simplify the problem of studying how people learn natural language, researchers use the artificial grammar learning (AGL) task. In this task, participants study letter strings constructed according to the rules of an artificial grammar and subsequently attempt to discriminate grammatical from ungrammatical test strings. Although the data from these experiments are usually analyzed by comparing the mean discrimination performance between experimental conditions, this practice discards information about the individual items and participants that could otherwise help uncover the particular features of strings associated with grammaticality judgments. However, feature analysis is tedious to compute, often complicated, and ill-defined in the literature. Moreover, the data violate the assumption of independence underlying standard linear regression models, leading to Type I error inflation. To solve these problems, we present AGSuite, a free Shiny application for researchers studying AGL. The suite's intuitive Web-based user interface allows researchers to generate strings from a database of published grammars, compute feature measures (e.g., Levenshtein distance) for each letter string, and conduct a feature analysis on the strings using linear mixed effects (LME) analyses. The LME analysis solves the inflation of Type I errors that afflicts more common methods of repeated measures regression analysis. Finally, the software can generate a number of graphical representations of the data to support an accurate interpretation of results. We hope the ease and availability of these tools will encourage researchers to take full advantage of item-level variance in their datasets in the study of AGL. We moreover discuss the broader applicability of the tools for researchers looking to conduct feature analysis in any field.

    To test the hypothesis that pleasure from artistic music is intellectual while that from popular music is physiological, this study investigated the different functional mechanisms between aesthetic appreciation of artistic and popular music using fMRI. 18 male non-musicians were scanned while they performed an aesthetic rating task for excerpts of artistic music, popular music and musical notes playing and singing (control). The rating scores of artistic and popular music excerpts were both significantly higher than that of control materials while the scores of them were not different. The fMRI results showed both artistic and popular conditions activated the VS and vmPFC, compared with control condition. When contrasted popular and artistic condition directly, we found popular music activated right putamen, while artistic music activated right mPFC. By parametric analysis, we found the activation of right putamen tracked the aesthetic ratings of popular music, whereas the BOLD signal in right mPFC tracked the aesthetic ratings of artistic music. These results indicate the reward induced by popular music is closer to a primary reward while that induced by artistic music is closer to a secondary reward. We also found artistic music activated ToM areas, including PCC/PC, arMFC and TPJ, when compared with popular music. And these areas also tracked aesthetic ratings of artistic music but not those of popular music. These results imply that the pleasure from former comes from cognitive empathy. In conclusion, this study gives clear neuronal evidences supporting the view that artistic music is of intelligence and social cognition involved while the popular music is of physiology.

    Full Text Available Identity and privacy concerns related to social media are the subject of widespread academic enquiry and mass media reporting. Although in most circumstances academic research tends to present identity play and online self­presentation as positive, media reporting in Australia makes much of the risks of identity theft, privacy breaches and online predators. This research explores the phenomenological experience of creating an online persona, focusing particularly on street artists. For street artists, the threat of unwanted exposure has to be balanced with the positive implications of sharing their creative work outside its geographical and temporal constraints. I argue that street artists use complex persona­creation strategies in order to both protect and promote themselves. The two street artists discussed in this article experience their engagement with social media and digital networks in ways that offer new insight into the opportunities and problems associated with the presentation of a persona online.

  8. Performance Analysis of the SIFT Operator for Automatic Feature Extraction and Matching in Photogrammetric Applications

    2009-05-01

    Full Text Available In the photogrammetry field, interest in region detectors, which are widely used in Computer Vision, is quickly increasing due to the availability of new techniques. Images acquired by Mobile Mapping Technology, Oblique Photogrammetric Cameras or Unmanned Aerial Vehicles do not observe normal acquisition conditions. Feature extraction and matching techniques, which are traditionally used in photogrammetry, are usually inefficient for these applications as they are unable to provide reliable results under extreme geometrical conditions (convergent taking geometry, strong affine transformations, etc. and for bad-textured images. A performance analysis of the SIFT technique in aerial and close-range photogrammetric applications is presented in this paper. The goal is to establish the suitability of the SIFT technique for automatic tie point extraction and approximate DSM (Digital Surface Model generation. First, the performances of the SIFT operator have been compared with those provided by feature extraction and matching techniques used in photogrammetry. All these techniques have been implemented by the authors and validated on aerial and terrestrial images. Moreover, an auto-adaptive version of the SIFT operator has been developed, in order to improve the performances of the SIFT detector in relation to the texture of the images. The Auto-Adaptive SIFT operator (A2 SIFT has been validated on several aerial images, with particular attention to large scale aerial images acquired using mini-UAV systems.

    The influence of Parkinson's disease (PD) as well as deep brain stimulation (DBS) on visual-artistic production of people who have been artists is unclear. We systematically assessed the artistic-creative productions of a patient with PD who was referred to us for management of a left subthalamic region (STN) DBS. The patient was an artist before her disease started, permitting us to analyze changes in her artistic-creative production over the course of the illness and during her treatment with DBS. We collected her paintings from four time periods: Time 1 (Early Pre-Presymptomatic), Time 2 (Later Presymptomatic), Time 3 (Symptomatic), and Time 4 (DBS Symptomatic). A total of 59 paintings were submitted to a panel of judges, who rated the paintings on 6 different artistic qualities including: aesthetics, closure, evocative impact, novelty, representation, technique. Aesthetics and evocative impact significantly declined from Time 2 to Time 4. Representation and technique indicated a curvilinear relationship, with initial improvement from Time 1 to Time 2 followed by a decline from Time 2 to Time 4. These results suggest that left STN/SNR-DBS impacted artistic performances in our patient. The reason for these alterations is not known, but it might be that alterations of left hemisphere functions induce a hemispheric bias reducing the influence the right hemisphere which is important for artistic creativity. The left hemisphere itself plays a critical role in artistic creativity and DBS might have altered left hemisphere functions or altered the mesolimbic system which might have also influenced creativity. Future studies will be required to learn how PD and DBS influence creativity.

    Aksan, N.; Schulenberg, T.; Squarer, D.

    2003-01-01

    Research Activities are ongoing worldwide to develop advanced nuclear power plants with high thermal efficiency for the purpose to improve their economical competitiveness. Within the 5th Framework Programme of the European Commission, a project has been launched with the main objective to assess the technical and economical feasibility of a high efficiency LWR operating at super critical pressure conditions. Several European research institutions, industrial partners and the University of Tokyo participated and worked in this common research project. Within the aims of the development of the HPLWR is to use both passive and active safety systems for performing safety related functions in the event of transients or accidents. Consequently substantial effort has been invested in order to define the safety features of the plant in a European environment, as well as to incorporate passive safety features into the design. Throughout this process, the European Utility Requirements (EUR) and requirements known from Generation IV initiative were considered as a guideline in general terms in order to include further advanced ideas. The HPLWR general features were compared to both requirements, indicating a potential to meet these. Since, the supercritical HPLWR represents a challenge for best-estimate safety codes like RELAP5, CATHARE and TRAB due to the fact that these codes were developed for two-phase or single-phase coolant at pressures far below critical point, work on the preliminary assessment of the appropriateness of these codes have been performed for selected relevant phenomena, and application of the codes to the selected transients on the basis of defined 'reference design'. An overview on their successful upgrade to supercritical pressures and application to some plant safety analysis are provided in the paper. Further elaborations in relation to future needs are also discussed. (author)

  20. Artistic Representation with Pulsed Holography

    International Nuclear Information System (INIS)

    Ishii, S

    2013-01-01

    This thesis describes artistic representation through pulsed holography. One of the prevalent practical problems in making holograms is object movement. Any movement of the object or film, including movement caused by acoustic vibration, has the same fatal results. One way of reducing the chance of movement is by ensuring that the exposure is very quick; using a pulsed laser can fulfill this objective. The attractiveness of using pulsed laser is based on the variety of materials or objects that can be recorded (e.g., liquid material or instantaneous scene of a moving object). One of the most interesting points about pulsed holograms is that some reconstructed images present us with completely different views of the real world. For example, the holographic image of liquid material does not appear fluid; it looks like a piece of hard glass that would produce a sharp sound upon tapping. In everyday life, we are unfamiliar with such an instantaneous scene. On the other hand, soft-textured materials such as a feather or wool differ from liquids when observed through holography. Using a pulsed hologram, we can sense the soft touch of the object or material with the help of realistic three-dimensional (3-D) images. The images allow us to realize the sense of touch in a way that resembles touching real objects. I had the opportunity to use a pulsed ruby laser soon after I started to work in the field of holography in 1979. Since then, I have made pulsed holograms of activities, including pouring water, breaking eggs, blowing soap bubbles, and scattering feathers and popcorn. I have also created holographic art with materials and objects, such as silk fiber, fabric, balloons, glass, flowers, and even the human body. Whenever I create art, I like to present the spectator with a new experience in perception. Therefore, I would like to introduce my experimental artwork through those pulsed holograms.

    2012-07-01

    We present a computerized method for the semi-automatic detection of contours in ultrasound images. The novelty of our study is the introduction of a fast and efficient image function relating to parametric active contour models. This new function is a combination of the gray-level information and first-order statistical features, called standard deviation parameters. In a comprehensive study, the developed algorithm and the efficiency of segmentation were first tested for synthetic images. Tests were also performed on breast and liver ultrasound images. The proposed method was compared with the watershed approach to show its efficiency. The performance of the segmentation was estimated using the area error rate. Using the standard deviation textural feature and a 5×5 kernel, our curve evolution was able to produce results close to the minimal area error rate (namely 8.88% for breast images and 10.82% for liver images). The image resolution was evaluated using the contrast-to-gradient method. The experiments showed promising segmentation results.

    This report describes research to identify and rank the factors that should be considered for an assessment of the radioactive containment capability of repository engineered features. Containment is to be achieved through the use of multiple barriers to radionuclide movement, including the waste, waste container, repository structures and backfill, and repository seals. A review of the literature is used to identify radionuclide mobilisation and transport processes for the anticipated environmental conditions, and to compile a data base of repository design features, functional requirements, and design objectives. For selected design components, the report identifies alternative designs and factors contributing to design, focusing on the requirements for a design process, design specifications, construction requirements, and quality assurance requirements for the both design and construction. Existing practice in large, underground civil construction projects is used as a part of comparison, in conjunction with reported performance assessments, to determine those areas in which the repository developer will need to provide additional data, justification, and documentation prior to construction to ensure that performance requirements can be achieved.

    Intertumor heterogeneity has been proposed as a potential mechanism to account for variability in cognitive performance in women diagnosed with breast cancer. The purpose of this study was to explore associations between variation in pathologic tumor features (PTFs) and variability in preadjuvant therapy cognitive performance in postmenopausal women newly diagnosed with early-stage breast cancer. Participants (N = 329) completed a comprehensive battery of neuropsychological tests to evaluate cognitive performance after primary surgery but prior to initiation of adjuvant anastrozole±chemotherapy. PTF data were abstracted from medical records. Robust multiple linear regression models were fit to estimate associations between individual PTFs and the cognitive function composite domain scores. All models controlled for age, estimated intelligence, and levels of depressive symptoms, anxiety, fatigue, and pain. Diagnosis of a HER2-positive tumor contributed to poorer verbal (b = -0.287, P = 0.018), visual (b = -0.270, P = 0.001), and visual working (b = -0.490, P Breast Cancer Assay Recurrence Score ® .) Our results suggest that certain PTFs related to more aggressive tumor phenotypes or inferior breast cancer prognosis may be implicated in poorer preadjuvant therapy cognitive performance. Follow-up studies that include a cognitive assessment before primary surgery should be conducted to further delineate the role of intertumor heterogeneity on cognitive performance. © 2016 The Authors.

    Full Text Available This is a qualitative investigation to analyse native dance in North-eastern Thailand. There were three objectives for this investigation, which were to study the history of Isan folk dance, current dance postures and ways to conserve the current dance postures of Isan folk artists. Research tools were interview, observation, participation, focus group discussion and workshop. The purposively selected research sample was composed of 3 groups of national artists. The findings show that Isan folk dancer shave their own unique dancing styles. Each artist has his or her own identity, which is constructed based on personal experience of dancing and singing. Mor lam is a dance used to accompany traditional Isansung poetry. Modern dance postures have been adapted from the traditional forms. Dance postures have been adapted from three primary sources: traditional literature, the ethnic and Lanchang dancing in the Lao People’s Democratic Republic and rhythmic Khon Kaen compositions. The conclusions of this investigation suggest that preservation of the dancing arts and postures should centre on the incorporation of new knowledge, as well as the continuation of traditional dance postures. Further research is required for people interested in performing arts conservation in other provinces and other traditional performing arts.

    Full Text Available We introduce a new motor parameter imagery paradigm using clench speed and clench force motor imagery. The time-frequency-phase features are extracted from mu rhythm and beta rhythms, and the features are optimized using three process methods: no-scaled feature using “MIFS” feature selection criterion, scaled feature using “MIFS” feature selection criterion, and scaled feature using “mRMR” feature selection criterion. Support vector machines (SVMs and extreme learning machines (ELMs are compared for classification between clench speed and clench force motor imagery using the optimized feature. Our results show that no significant difference in the classification rate between SVMs and ELMs is found. The scaled feature combinations can get higher classification accuracy than the no-scaled feature combinations at significant level of 0.01, and the “mRMR” feature selection criterion can get higher classification rate than the “MIFS” feature selection criterion at significant level of 0.01. The time-frequency-phase feature can improve the classification rate by about 20% more than the time-frequency feature, and the best classification rate between clench speed motor imagery and clench force motor imagery is 92%. In conclusion, the motor parameter imagery paradigm has the potential to increase the direct control commands for BCI control and the time-frequency-phase feature has the ability to improve BCI classification accuracy.

  7. The effects of gamelike features and test location on cognitive test performance and participant enjoyment

    Jim Lumsden

    2016-07-01

    Full Text Available Computerised cognitive assessments are a vital tool in the behavioural sciences, but participants often view them as effortful and unengaging. One potential solution is to add gamelike elements to these tasks in order to make them more intrinsically enjoyable, and some researchers have posited that a more engaging task might produce higher quality data. This assumption, however, remains largely untested. We investigated the effects of gamelike features and test location on the data and enjoyment ratings from a simple cognitive task. We tested three gamified variants of the Go-No-Go task, delivered both in the laboratory and online. In the first version of the task participants were rewarded with points for performing optimally. The second version of the task was framed as a cowboy shootout. The third version was a standard Go-No-Go task, used as a control condition. We compared reaction time, accuracy and subjective measures of enjoyment and engagement between task variants and study location. We found points to be a highly suitable game mechanic for gamified cognitive testing because they did not disrupt the validity of the data collected but increased participant enjoyment. However, we found no evidence that gamelike features could increase engagement to the point where participant performance improved. We also found that while participants enjoyed the cowboy themed task, the difficulty of categorising the gamelike stimuli adversely affected participant performance, increasing No-Go error rates by 28% compared to the non-game control. Responses collected online vs. in the laboratory had slightly longer reaction times but were otherwise very similar, supporting other findings that online crowdsourcing is an acceptable method of data collection for this type of research.

  10. Feature Extraction of Event-Related Potentials Using Wavelets: An Application to Human Performance Monitoring

    Science.gov (United States)

    Trejo, Leonard J.; Shensa, Mark J.; Remington, Roger W. (Technical Monitor)

    1998-01-01

    This report describes the development and evaluation of mathematical models for predicting human performance from discrete wavelet transforms (DWT) of event-related potentials (ERP) elicited by task-relevant stimuli. The DWT was compared to principal components analysis (PCA) for representation of ERPs in linear regression and neural network models developed to predict a composite measure of human signal detection performance. Linear regression models based on coefficients of the decimated DWT predicted signal detection performance with half as many f ree parameters as comparable models based on PCA scores. In addition, the DWT-based models were more resistant to model degradation due to over-fitting than PCA-based models. Feed-forward neural networks were trained using the backpropagation,-, algorithm to predict signal detection performance based on raw ERPs, PCA scores, or high-power coefficients of the DWT. Neural networks based on high-power DWT coefficients trained with fewer iterations, generalized to new data better, and were more resistant to overfitting than networks based on raw ERPs. Networks based on PCA scores did not generalize to new data as well as either the DWT network or the raw ERP network. The results show that wavelet expansions represent the ERP efficiently and extract behaviorally important features for use in linear regression or neural network models of human performance. The efficiency of the DWT is discussed in terms of its decorrelation and energy compaction properties. In addition, the DWT models provided evidence that a pattern of low-frequency activity (1 to 3.5 Hz) occurring at specific times and scalp locations is a reliable correlate of human signal detection performance.

  11. Neural Determinants of Task Performance during Feature-Based Attention in Human Cortex

    2018-01-01

    Abstract Studies of feature-based attention have associated activity in a dorsal frontoparietal network with putative attentional priority signals. Yet, how this neural activity mediates attentional selection and whether it guides behavior are fundamental questions that require investigation. We reasoned that endogenous fluctuations in the quality of attentional priority should influence task performance. Human subjects detected a speed increment while viewing clockwise (CW) or counterclockwise (CCW) motion (baseline task) or while attending to either direction amid distracters (attention task). In an fMRI experiment, direction-specific neural pattern similarity between the baseline task and the attention task revealed a higher level of similarity for correct than incorrect trials in frontoparietal regions. Using transcranial magnetic stimulation (TMS), we disrupted posterior parietal cortex (PPC) and found a selective deficit in the attention task, but not in the baseline task, demonstrating the necessity of this cortical area during feature-based attention. These results reveal that frontoparietal areas maintain attentional priority that facilitates successful behavioral selection. PMID:29497703

  12. Real Vegan Cheese and the Artistic Critique of Biotechnology

    Rebecca Wilbanks

    2017-04-01

    Full Text Available Drawing on the case study of Real Vegan Cheese (RVC, a synthetic biology project housed in a community lab or “biohackerspace,” I argue that biohacking performs an “artistic critique” of the bioeconomy. Following Boltanski and Chiapello’s use of the term, the “artistic critique” pits values of autonomy and creativity against a view of capitalist production as standardized and alienating, represented (in the case of biotechnology by Monsanto’s monoculture GMOs. In this way, biohacking is depicted as liberating biotechnology from the constraints of corporate and academic institutions. Through the use of design fiction and a playful aesthetic, projects such as RVC demonstrate a more legitimate––with respect to the values of the artistic critique––mode of production for a new generation of biotechnology products, one that is portrayed as driven primarily by ethical and aesthetic values rather than the profit motive. This analysis highlights the role that aesthetic and affective strategies play in advancing particular sociotechnical visions, and the way that biohacking projects operate in symbiosis with incumbent institutions even as they define themselves in opposition to them. Finally, it suggests that biohacking has certain limitations when considered as a form of public engagement with science.

    2013-12-01

    Full Text Available OGC Web Feature Service (WFS and Web Coverage Service (WCS specifications allow interoperable access to distributed geospatial data made available through spatial data infrastructures (SDIs. To ensure that a service is sufficiently responsive to fulfill users’ expectations and requirements, performance of services must be measured and monitored to track latencies, bottlenecks, and errors that may negatively influence its over- all quality. Despite the importance of data retrieval and access, little research has been published on this topic and mostly concentrates on the usability of services when integrating distributed data sources. Considering these issues, this paper extends and validates the FOSS4G approach to measure the server-side performance of different WFS and WCS services provided by various software implementations; and provides guidance to data providers looking to improve the quality of their services. Our results show that performance of tested implementations is generally satisfactory and memory tuning/data and storage optimization are essential to handle increased efficiency and reliability of services.

    2017-01-01

    Full Text Available A main critical factor on embedding process in any text steganography method is a key used known as stego key. This factor will be influenced the success of the embedding process of text steganography method to hide a message from third party or any adversary. One of the important aspects on embedding process in text steganography method is the fitness performance of the stego key. Three parameters of the fitness performance of the stego key have been identified such as capacity ratio, embedded fitness ratio and saving space ratio. It is because a better as capacity ratio, embedded fitness ratio and saving space ratio offers of any stego key; a more message can be hidden. Therefore, main objective of this paper is to analyze three features coding based namely CALP, VERT and QUAD of stego keys in text steganography on their capacity ratio, embedded fitness ratio and saving space ratio. It is found that CALP method give a good effort performance compared to VERT and QUAD methods.

    2013-08-01

    Anatomy has a long history that started with dissection of animals and then expanded and flourished thanks to dissections performed on human bodies. Artists had a crucial role in uncovering the secrets of human anatomy. While most studies have focused on the influence of famous Renaissance artists on human anatomy studies, the anatomical drawings by pre-Renaissance artists and local craftsmen have remained in their shadow. One of the most popular artistic genres in which complete or parts of human skeletons appear is the Dance of Death (Danse Macabre). This article is an anthropological study of two medieval Dance of Death frescoes that are unusual in being relatively early as well as accurately datable. A comparative morphological analysis of the two late 15th century works present in Istria has been conducted. The two works were painted by two local masters and show how the artists filled the gaps in their knowledge of human anatomy mostly with insights into animal bones and imagination. Their artworks, even though only 16 years apart, demonstrate substantial differences in the representation of the skeletons. The article argues that the history of medicine and of art could make good use of osteology and physical anthropology in attempts to define and understand how anatomical knowledge developed among pre-Renaissance and post-Renaissance artists and local people. © 2013 Anatomical Society.

    We study the use of the generative systems known as computational ecosystems to convey artistic and narrative aims. These are virtual worlds running on computers, composed of agents that trade units of energy and emulate cycles of life and behaviors adapted from biological life forms. In this article we propose a conceptual framework in order to understand these systems, which are involved in processes of authorship and interpretation that this investigation analyzes in order to identify critical instruments for artistic exploration. We formulate a model of narrative that we call system stories (after Mitchell Whitelaw), characterized by the dynamic network of material and conceptual processes that define these artefacts. They account for narrative constellations with multiple agencies from which meaning and messages emerge. Finally, we present three case studies to explore the potential of this model within an artistic and generative domain, arguing that this understanding expands and enriches the palette of the language of these systems.

    Research has shown that creative style, as measured by the Kirton Adaption-Innovation Inventory (KAI; M. J. Kirton, 1976), is correlated with more than 30 different personality traits. In this article, the author demonstrates that many of these correlations can be understood within the framework of the Five-Factor Model of personality and shows that the predominant correlates of creative style are personality indicators in the domains of the factors Conscientiousness, Openness to Experience, and, to a lesser extent, Extraversion. These findings provide a basis for comparing the personality traits associated with creative style and occupational creativity. High scorers on the KAI (innovators) differ from both average and creative scientists but have personality characteristics similar to those of artists. This finding suggests that the artistic personality may be more common than is generally supposed and that common factors might underlie both artistic endeavor and creative style.

    Full Text Available Structural development implies control and capability of the expression usage in terms of independent creative expression and making. Understanding of structural development of child's artistic expression as a phenomenon (which is suitable to child's age has some implications on methodical acts considering the artistic education of children and youngsters. Therefore, it is of unexceptional importance to know these laws as well as methodical acts which encourage the structural development of artistic capabilities from an early age. Various experts dealt with this phenomenon, particularly Bogomil Karlavaris. In his methodical research, he has given an unexceptional part to this problem. It has been a starting point for analysis of certain methodical questions which are included in this work.

    We present a novel artistic-verisimilitude driven system for watercolor rendering of images and photos. Our system achieves realistic simulation of a set of important characteristics of watercolor paintings that have not been well implemented before. Specifically, we designed several image filters to achieve: 1) watercolor-specified color transferring; 2) saliency-based level-of-detail drawing; 3) hand tremor effect due to human neural noise; and 4) an artistically controlled wet-in-wet effect in the border regions of different wet pigments. A user study indicates that our method can produce watercolor results of artistic verisimilitude better than previous filter-based or physical-based methods. Furthermore, our algorithm is efficient and can easily be parallelized, making it suitable for interactive image watercolorization.

    Full Text Available Abstract Background High-density oligonucleotide arrays are effective tools for genotyping numerous loci simultaneously. In small genome species (genome size: Results We compared the single feature polymorphism (SFP detection performance of whole-genome and transcript hybridizations using the Affymetrix GeneChip® Rice Genome Array, using the rice cultivars with full genome sequence, japonica cultivar Nipponbare and indica cultivar 93-11. Both genomes were surveyed for all probe target sequences. Only completely matched 25-mer single copy probes of the Nipponbare genome were extracted, and SFPs between them and 93-11 sequences were predicted. We investigated optimum conditions for SFP detection in both whole genome and transcript hybridization using differences between perfect match and mismatch probe intensities of non-polymorphic targets, assuming that these differences are representative of those between mismatch and perfect targets. Several statistical methods of SFP detection by whole-genome hybridization were compared under the optimized conditions. Causes of false positives and negatives in SFP detection in both types of hybridization were investigated. Conclusions The optimizations allowed a more than 20% increase in true SFP detection in whole-genome hybridization and a large improvement of SFP detection performance in transcript hybridization. Significance analysis of the microarray for log-transformed raw intensities of PM probes gave the best performance in whole genome hybridization, and 22,936 true SFPs were detected with 23.58% false positives by whole genome hybridization. For transcript hybridization, stable SFP detection was achieved for highly expressed genes, and about 3,500 SFPs were detected at a high sensitivity (> 50% in both shoot and young panicle transcripts. High SFP detection performances of both genome and transcript hybridizations indicated that microarrays of a complex genome (e.g., of Oryza sativa can be

    Full Text Available At present, the sports dance has entered every stage of the people’s life, has become the public’s favorite sport. Sports dance has been well developed. This article mainly uses the literature material law to carry on the detailed analysis to the sports dance constitution, elaborated in detail the sports dance artistic expression. The composition of sports dance elements; sports dance is a form of dance art show; sports dance through the dance art can be divided into three aspects, namely, form, music, shape of the expressive force. In this paper, the study will be more in-depth excavation of the cultural connotation of sports dance, and promote the development of sports dance can be more comprehensive. In 20s of last century, Chinese Sports Dance Association officially joined the International Sports Dance Association, which also makes our country’s sports dance and international exchange more frequent. However, due to China’s sports dance sports dance learning time is not long, while learning is influenced by Chinese traditional culture, the sports dance movements are too conservative, there is a very large gap and international enthusiasm, bold and unrestrained, the pursuit of individual sports dance in the dance style, music and performance hand. Sports dance originated from abroad, it is produced in the daily life of people in foreign countries. China’s domestic sports dance players in learning dance at the same time, the production and the connotation of dance is not very understanding, therefore, it is difficult to better reflect the emotional expression of sports dance. Although the sports dance is a kind of similar to the competitive projects, but it is also a kind of dance culture, and to constitute a force from the dance art show a detailed study, detailed mining playing officer of sports dance performance further, reducing China’s sports dance and international sports dance gap.

    Full Text Available Under the experimental Fluxus and shaped by their attraction to certain premises of Zen Buddhism, including koan, many artists began to raise all kinds of proposals, from object-based practices to actions, but generally guided by the mental structure of zen koan itself, for example, irony, humor and meditative processes. These artists were able to give a previously nonexistent prominence both actions based on daily events, such as objects that had failed to interest social. In this way, they managed to eliminate many of the barriers between art and life.

    Full text: Full text: The Engineered Safety Features-Component Control System (ESF-CCS) controls the engineered safety features of a Nuclear Power Plant such as Solenoid Operated Valves (SOV), Motor Operated Valves (MOV), pumps, dampers, etc. to mitigate the effects of a Design Basis Accident (DBA) or an abnormal operation. ESF-CCS serves as an interface system between the Plant Protection System (PPS) and remote actuation devices. ESF-CCS is composed of fault tolerant Group Controllers GC, Loop Controllers (LC), ESF-CCS Test and Interface Processor (ETIP) and Cabinet Operator Module (COM) and Control Channel Gateway (CCG) etc. GCs in each division are designed to be fully independent triple configuration, which perform system level NSSS and BOP ESFAS logic (2-out-of-4 logic and l-out-of-2 logic, respectively) making it possible to test each GC individually during normal operation. In the existing configuration, the safety-related plant component control is part of the Plant Control System (PCS) non-safety system. For increased safety and reliability, this design change incorporates this part into the LCs, and is therefore designed according to the safety-critical system procedures. The test and diagnosis capabilities of ETIP and COM are reinforced. By means of an automatic periodic test for all main functions of the system, it is possible to quickly determine an abnormal status of the system, and to decrease the elapsed time for tests, thus effectively increasing availability. ESF-CCS consists of four independent divisions (A, B, C, and D) in the Advanced Power Reactor 1400 (APR1400). One prototype division is being manufactured and will be tested

    Full Text Available Cosensitization based on two or multiple dyes as “dye cocktails” can hit the target on compensating and broadening light-harvesting region. Two indoline D-A-π-A motif sensitizers (WS-2 and WS-39 that possess similar light response area but distinctly reversed feature in photovoltaic performance are selected as the specific cosensitization couple. That is, WS-2 shows quite high photocurrent but low photovoltage, and WS-39 gives relatively low photocurrent but quite high photovoltage. Due to the obvious “barrel effect”, both dyes show medium PCE around 8.50%. In contrast with the previous cosensitization strategy mostly focused on the compensation of light response region, herein we perform different cosensitization sequence, for taking insight into the balance of photocurrent and photovoltage, and achieving the synergistic improvement in power conversion efficiency (PCE. Electronic impedance spectra (EIS indicate that exploiting dye WS-39 with high VOC value as the primary sensitizer can repress the charge recombination more effectively, resulting in superior VOC rather than using dye WS-2 with high JSC as the primary sensitizer. As a consequence, a high PCE value of 9.48% is obtained with the delicate cosensitization using WS-39 as primary dye and WS-2 as accessory dye, which is higher than the corresponding devices sensitized by each individual dye (around 8.48–8.67%. It provides an effective optimizing strategy of cosensitization how to combine the individual dye advantages for developing highly efficient solar cells.

    Full Text Available Quran is an artful allegory of a scientific-literary text that presents numerous guidelines to achieve perfection and at the same time it shines like a sun in the sky of rhetoric and eloquence. One of the immortal aspects of this divine book is its educational aspect and Luqman Surah is considered one of the prominent ones. The most common method to convey information, persuasion and motivation of audiences in literary work is using artistic images. Suitability for meaning is a condition for the success of artistic image which holy Quran is an outstanding instance of it. In fact, artistic image is a beautiful picture that imagination and emotion breathe the spirit of life in its body. Emphasizing the virtues of words especially stress, pun, rhyme, repetition, redundancy and brevity is a marker of valuing the Quran's on the issue of education. The use of allegory, light tone, soft rhyme, short, clear and harmonic sentences without any ambiguity is applied in order to understand the issue and persuades and motivates audiences. This study implements discourse analysis by investigating the characteristic of images in Luqman Surah. In this regard, artistic features of Quran and its distinction from other library texts become more evident.

    MicroRNAs (miRNAs) are short nucleotide sequences that form a typical hairpin structure which is recognized by a complex enzyme machinery. It ultimately leads to the incorporation of 18-24 nt long mature miRNAs into RISC where they act as recognition keys to aid in regulation of target mRNAs. It is involved to determine miRNAs experimentally and, therefore, machine learning is used to complement such endeavors. The success of machine learning mostly depends on proper input data and appropriate features for parameterization of the data. Although, in general, two-class classification (TCC) is used in the field; because negative examples are hard to come by, one-class classification (OCC) has been tried for pre-miRNA detection. Since both positive and negative examples are currently somewhat limited, feature selection can prove to be vital for furthering the field of pre-miRNA detection. In this study, we compare the performance of OCC and TCC using eight feature selection methods and seven different plant species providing positive pre-miRNA examples. Feature selection was very successful for OCC where the best feature selection method achieved an average accuracy of 95.6%, thereby being ∼29% better than the worst method which achieved 66.9% accuracy. While the performance is comparable to TCC, which performs up to 3% better than OCC, TCC is much less affected by feature selection and its largest performance gap is ∼13% which only occurs for two of the feature selection methodologies. We conclude that feature selection is crucially important for OCC and that it can perform on par with TCC given the proper set of features.

  15. Search performance is better predicted by tileability than presence of a unique basic feature

    Science.gov (United States)

    Chang, Honghua; Rosenholtz, Ruth

    2016-01-01

    Traditional models of visual search such as feature integration theory (FIT; Treisman & Gelade, 1980), have suggested that a key factor determining task difficulty consists of whether or not the search target contains a “basic feature” not found in the other display items (distractors). Here we discriminate between such traditional models and our recent texture tiling model (TTM) of search (Rosenholtz, Huang, Raj, Balas, & Ilie, 2012b), by designing new experiments that directly pit these models against each other. Doing so is nontrivial, for two reasons. First, the visual representation in TTM is fully specified, and makes clear testable predictions, but its complexity makes getting intuitions difficult. Here we elucidate a rule of thumb for TTM, which enables us to easily design new and interesting search experiments. FIT, on the other hand, is somewhat ill-defined and hard to pin down. To get around this, rather than designing totally new search experiments, we start with five classic experiments that FIT already claims to explain: T among Ls, 2 among 5s, Q among Os, O among Qs, and an orientation/luminance-contrast conjunction search. We find that fairly subtle changes in these search tasks lead to significant changes in performance, in a direction predicted by TTM, providing definitive evidence in favor of the texture tiling model as opposed to traditional views of search.

    For building a new iris template, this paper proposes a strategy to fuse different portions of iris based on machine learning method to evaluate local quality of iris. There are three novelties compared to previous work. Firstly, the normalized segmented iris is divided into multitracks and then each track is estimated individually to analyze the recognition accuracy rate (RAR). Secondly, six local quality evaluation parameters are adopted to analyze texture information of each track. Besides, particle swarm optimization (PSO) is employed to get the weights of these evaluation parameters and corresponding weighted coefficients of different tracks. Finally, all tracks' information is fused according to the weights of different tracks. The experimental results based on subsets of three public and one private iris image databases demonstrate three contributions of this paper. (1) Our experimental results prove that partial iris image cannot completely replace the entire iris image for iris recognition system in several ways. (2) The proposed quality evaluation algorithm is a self-adaptive algorithm, and it can automatically optimize the parameters according to iris image samples' own characteristics. (3) Our feature information fusion strategy can effectively improve the performance of iris recognition system.

    Atienza-Márquez, Antonio; Bruno, Joan Carles; Coronas, Alberto; Korolija, Ivan; Greenough, Richard; Wright, Andy

    2017-01-01

    Currently, the electrical efficiency of photovoltaic (PV) solar cells ranges between 5–25%. One of the most important parameters that affects the electrical efficiency of a PV collector is the temperature of its cells: the higher temperature, the lower is the efficiency. Photovoltaic/thermal (PV/T) technology is a potential solution to ensure an acceptable solar energy conversion. The PV/T technology produces both electrical and thermal energy simultaneously. It is suitable for low temperature applications (25–40 o C) and overall efficiency increases compared to individual collectors. This paper describes an installation in a single-family house where PV/T collectors are coupled with a ground heat exchanger and a heat pump for domestic hot water and space heating purposes. The aim of this work is twofold. First, the features of the PV/T technology are analyzed. Second, a model of a flat-plate PV/T water collector was developed in TRNSYS in order to analyze collectors performance. (author)

  5. Cognitive Processes Underlying the Artistic Experience

    Full Text Available Based on the field of aesthetics, for centuries philosophers and more recently scientists have been concerned with understanding the artistic experience focusing on emotional responses to the perception of artworks. By contrast, in the last decades, evolutionary biology has been concerned with explaining the artistic experience by focusing on the cognitive processes underlying this experience. Up until now, the cognitive mechanisms that allow humans to experience objects and events as art remain largely unexplored and there is still no conventional use of terms for referring to the processes which may explain why the artistic experience is characteristically human and universal to human beings (Dissanayake, 1992, p. 24; Donald, 2006, p. 4. In this paper, I will first question whether it is productive to understand the artistic experience in terms of perception and emotion, and I will subsequently propose a possible alternative explanation to understand this experience. Drawing upon the work of Ellen Dissanayake (1992, 2000, 2015, Merlin Donald (2001, 2006, 2013, Antonio Damasio (1994, 2000, 2003, 2010, Barend van Heusden (2004, 2009, 2010, and Alejandra Wah (2014, I will argue that this experience is characterized by particular degrees of imagination and consciousness.

    2013-01-01

    Creativity is the development of a new or novel understanding--insight that leads to the expression of orderly relationships (e.g., finding and revealing the thread that unites). Visual artistic creativity plays an important role in the quality of human lives, and the goal of this chapter is to describe some of the brain mechanisms that may be important in visual artistic creativity. The initial major means of learning how the brain mediates any activity is to understand the anatomy and physiology that may support these processes. A further understanding of specific cognitive activities and behaviors may be gained by studying patients who have diseases of the brain and how these diseases influence these functions. Physiological recording such as electroencephalography and brain imaging techniques such as PET and fMRI have also allowed us to gain a better understanding of the brain mechanisms important in visual creativity. In this chapter, we discuss anatomic and physiological studies, as well as neuropsychological studies of healthy artists and patients with neurological disease that have helped us gain some insight into the brain mechanisms that mediate artistic creativity. © 2013 Elsevier B.V.

    To determine the diagnostic performance of standing computerized tomography (SCT) of the knee for osteophytes and subchondral cysts compared with fixed-flexion radiography, using MRI as the reference standard. Twenty participants were recruited from the Multicenter Osteoarthritis Study. Participants' knees were imaged with SCT while standing in a knee-positioning frame, and with postero-anterior fixed-flexion radiography and 1T MRI. Medial and lateral marginal osteophytes and subchondral cysts were scored on bilateral radiographs and coronal SCT images using the OARSI grading system and on coronal MRI using Whole Organ MRI Scoring. Imaging modalities were read separately with images in random order. Sensitivity, specificity and accuracy for the detection of lesions were calculated and differences between modalities were tested using McNemar's test. Participants' mean age was 66.8 years, body mass index was 29.6 kg/m(2) and 50% were women. Of the 160 surfaces (medial and lateral femur and tibia for 40 knees), MRI revealed 84 osteophytes and 10 subchondral cysts. In comparison with osteophytes and subchondral cysts detected by MRI, SCT was significantly more sensitive (93 and 100%; p osteophytes) than plain radiographs (sensitivity 60 and 10% and accuracy 79 and 94%, respectively). For osteophytes, differences in sensitivity and accuracy were greatest at the medial femur (p = 0.002). In comparison with MRI, SCT imaging was more sensitive and accurate for detection of osteophytes and subchondral cysts than conventional fixed-flexion radiography. Additional study is warranted to assess diagnostic performance of SCT measures of joint space width, progression of OA features and the patellofemoral joint.

  16. Conference Report: Circles within Circles—Qualitative Methodology and the Arts: The Researcher as Artist

    Full Text Available This short report describes a qualitative research colloquium in Swansea, UK, supported by AstraZeneca. The meeting was chaired by Frances RAPPORT and Paul WAINWRIGHT and was attended by 40 participants, representing a range of professional and academic backgrounds from the UK and beyond. The colloquium, built on the idea of links between new qualitative methodologies and the arts, sought to explore what happens when researchers and artists talk to one another; the premise was that qualitative research and the arts have much in common. Presentations from qualitative methodologists and artists were scheduled to run in parallel with one another. Artists and researchers were encouraged to discuss their work in terms of the productive process and expressive representation and to share applications and ideas. Recurrent themes centred on form, structure, content and meaning. The message that emerged from the two days was that the artistic creative process and qualitative research are inextricably bound up with these concerns. Artist and researcher take experience and seek to translate it into a form that others can in turn experience and interpret. This requires an engagement on the part of researcher and artist, a commitment to being truthful rather than being on a quest for truth. Qualitative research and the creative or performative process thus have strong similarities, of process and outcome. However, there are also fundamental differences in the social complexities of the two practices, their goals and purposes, and the intentions that lie behind them. Nevertheless, artists, performers and qualitative researchers appear to have much in common and the possibilities for future collaborations of this kind look very exciting.

    The Japanese Respiratory Society guidelines propose a differential diagnosis for atypical pneumonia and bacterial pneumonia using a scoring system for the selection of appropriate antibiotic. In order to improve this scoring system, the guidelines are seeking new specific parameter. The purpose of this study was to clarify the pattern of abnormalities with Mycoplasma pneumoniae pneumonia on chest computed tomography (CT) and whether the radiographic findings could distinguish M. pneumoniae pneumonia from Streptococcus pneumoniae pneumonia. A retrospective review was performed of the CT findings of 64 cases and 68 cases where M. pneumoniae and S. pneumoniae, respectively, were the only pathogen identified by the panel of diagnostic tests used. Of the 64 patients with M. pneumoniae pneumonia, bronchial wall thickening was observed most frequently (81%), followed by centrilobular nodules (78%), ground-glass attenuation (78%), and consolidation (61%). Bronchial wall thickening and centrilobular nodules were observed more often in M. pneumoniae patients than in S. pneumoniae patients (p < 0.0001). The presence of bilateral bronchial wall thickening or centrilobular nodules was only seen in patients with M. pneumoniae pneumonia. Using the scoring system of the Japanese Respiratory Society guidelines and chest CT findings, 97% of M. pneumoniae patients were suspected to be M. pneumoniae pneumonia without serology. When comparing the CT findings between early stage and progressed stage in the same patients with severe pneumonia, the radiographic features of early stage M. pneumoniae pneumonia were not observed clearly in the progressed stage. The present results indicate that the diagnosis of M. pneumoniae pneumonia would appear to be reliable when found with a combination of bronchial wall thickening and centrilobular nodules in the CT findings. However, these CT findings are not observed in progressed severe M. pneumoniae pneumonia patients

    Body dimensions and body composition of children participating in artistic activities, such as gymnastics and many types of dancing, are important factors in performance improvement. The present study aimed to determine the reliability of a series of selected anthropometric measurements in young male and female gymnasts. Segment lengths, body breadths, circumferences, and skinfold thickness were measured in 20 young gymnasts by the same experienced examiner, using portable and easy-to-use instruments. All parameters were measured twice (test-retest) under the same conditions within a week's period. The high intra-class correlation coefficient (ICC) values ranging from 0.87 to 0.99, as well as the low coefficient of variation (CV) values (artistic gymnasts. Therefore, these measurements could contribute to further research in this field of investigation, helping to monitor young artistic gymnasts' growth status and identify specific characteristics for increased performance in this sport.

    2017-12-01

    Full Text Available OBJECTIVE: To compare 2D and 3D radiomics features prognostic performance differences in CT images of non-small cell lung cancer (NSCLC. METHOD: We enrolled 588 NSCLC patients from three independent cohorts. Two sets of 463 patients from two different institutes were used as the training cohort. The remaining cohort with 125 patients was set as the validation cohort. A total of 1014 radiomics features (507 2D features and 507 3D features correspondingly were assessed. Based on the dichotomized survival data, 2D and 3D radiomics indicators were calculated for each patient by trained classifiers. We used the area under the receiver operating characteristic curve (AUC to assess the prediction performance of trained classifiers (the support vector machine and logistic regression. Kaplan–Meier and Cox hazard survival analyses were also employed. Harrell's concordance index (C-Index and Akaike's information criteria (AIC were applied to assess the trained models. RESULTS: Radiomics indicators were built and compared by AUCs. In the training cohort, 2D_AUC = 0.653, 3D_AUC = 0.671. In the validation cohort, 2D_AUC = 0.755, 3D_AUC = 0.663. Both 2D and 3D trained indicators achieved significant results (P < .05 in the Kaplan-Meier analysis and Cox regression. In the validation cohort, 2D Cox model had a C-Index = 0.683 and AIC = 789.047; 3D Cox model obtained a C-Index = 0.632 and AIC = 799.409. CONCLUSION: Both 2D and 3D CT radiomics features have a certain prognostic ability in NSCLC, but 2D features showed better performance in our tests. Considering the cost of the radiomics features calculation, 2D features are more recommended for use in the current study.

  5. Artistic talent in dyslexia--a hypothesis.

    Chakravarty, Ambar

    2009-10-01

    The present article hints at a curious neurocognitive phenomenon of development of artistic talents in some children with dyslexia. The article also takes note of the phenomenon of creating in the midst of language disability as observed in the lives of such creative people like Leonardo da Vinci and Albert Einstein who were most probably affected with developmental learning disorders. It has been hypothesised that a developmental delay in the dominant hemisphere most likely 'disinhibits' the non-dominant parietal lobe to unmask talents, artistic or otherwise, in some such individuals. The present hypothesis follows the phenomenon of paradoxical functional facilitation described earlier. It has been suggested that children with learning disorders be encouraged to develop such hidden talents to full capacity, rather than be subjected to overemphasising on the correction of the disturbed coded symbol operations, in remedial training.

    Creativity is the ability to produce original and valuable ideas or behaviors. In real life, artistic and scientific creativity promoted the development of human civilization; however, to date, no studies have systematically investigated differences in the brain structures responsible for artistic and scientific creativity in a large sample. Using voxel-based morphometry (VBM), this study identified differences in regional gray matter volume (GMV) across the brain between artistic and scientific creativity (assessed by the Creative Achievement Questionnaire) in 356 young, healthy subjects. The results showed that artistic creativity was significantly negatively associated with the regional GMV of the supplementary motor area (SMA) and anterior cingulate cortex (ACC). In contrast, scientific creativity was significantly positively correlated with the regional GMV of the left middle frontal gyrus (MFG) and left inferior occipital gyrus (IOG). Overall, artistic creativity was associated with the salience network (SN), whereas scientific creativity was associated with the executive attention network and semantic processing. These results may provide an effective marker that can be used to predict and evaluate individuals' creative performance in the fields of science and art.

    Full Text Available The paper presents the technology and organization of the artistic cast production. On the basis of the actual cast production system, the manufacturing process was shown, in particular sand–piece moulding, which is a very important process and a time-consuming part of the entire manufacture of the casts. The current state of the production process as well as the organization of the work and production technology were analysed with the use of methods and techniques of production improvement, the Lean Manufacturing concept and computer systems. The results of the analysis and studies were shown with use of schemes and graphs of the layout of the production resources, a flow chart of the production process, value stream mapping, and a costs table for the production and modernization of the moulding stage. The work has shown that there are possibilities to improve the artistic cast production system. This improvement leads to increased productivity, lower production costs of artistic casts and increased competitiveness of the foundry.

    Caricatures are a form of humorous visual art, usually created by skilled artists for the intention of amusement and entertainment. In this paper, we present a novel approach for automatic generation of digital caricatures from facial photographs, which capture artistic deformation styles from hand-drawn caricatures. We introduced a pseudo stress-strain model to encode the parameters of an artistic deformation style using "virtual" physical and material properties. We have also developed a software system for performing the caricaturistic deformation in 3D which eliminates the undesirable artifacts in 2D caricaturization. We employed a Multilevel Free-Form Deformation (MFFD) technique to optimize a 3D head model reconstructed from an input facial photograph, and for controlling the caricaturistic deformation. Our results demonstrated the effectiveness and usability of the proposed approach, which allows ordinary users to apply the captured and stored deformation styles to a variety of facial photographs.

    Baldwin, Joseph; Burleigh, Alistair; Pepperell, Robert

    2014-01-01

    Which is the most accurate way to depict space in our visual field? Linear perspective, a form of geometrical perspective, has traditionally been regarded as the correct method of depicting visual space. But artists have often found it is limited in the angle of view it can depict; wide-angle scenes require uncomfortably close picture viewing distances or impractical degrees of enlargement to be seen properly. Other forms of geometrical perspective, such as fisheye projections, can represent wider views but typically produce pictures in which objects appear distorted. In this study we created an artistic rendering of a hemispherical visual space that encompassed the full visual field. We compared it to a number of geometrical perspective projections of the same space by asking participants to rate which best matched their visual experience. We found the artistic rendering performed significantly better than the geometrically generated projections.

    Banerjee, Mita; Wohlmann, Anita; Dahm, Ralf

    2017-01-01

    This article discusses the ways in which artists have incorporated or failed to incorporate the aging process of their bodies into their art. Using Russian ballet dancer Mikhail Baryshnikov and the French painter Claude Monet as cases in point, we explore situations in which physical changes brought about by aging compromises artists' ability to engage with their artistic medium. Connecting Monet's oeuvre and Baryshnikov's dance performances to life writing accounts, we draw on John Paul Eakin's concept of "living autobiographically": In this vein, life writing research does not only have to take into account concepts of identity as they emerge from life writing narratives, but it also needs to explore the somatic, corporeal and material dimensions of these narratives.

    Brain computer interfaces (BCIs) translate brain activity into computer commands. To enhance the performance of a BCI, it is necessary to improve the feature extraction techniques being applied to decode the users' intentions. Objective comparison methods are needed to analyze different feature extraction techniques. One possibility is to use the classifier performance as a comparative measure. In this work the effect of several variables that affect the behaviour of linear discriminant analysis (LDA) has been studied when used to distinguish between electroencephalographic signals with and without the presence of event related potentials (ERPs). The error rate (ER) and the area under the receiver operating characteristic curve (AUC) were used as performance estimators of LDA. The results show that the number of characteristics, the degree of balance of the training patterns set and the number of averaged trials affect the classifier's performance and therefore, must be considered in the design of the integrated system.

  2. The future of holographic technologies and their use by artists

    Science.gov (United States)

    Oliveira, S.; Richardson, M.

    2013-02-01

    The use of holographic technologies in the past has faced resistance in the artistic field. The most conservative artists and critiques saw the term "holographic" more as a technical subject than an artistic one. Nevertheless, to explore new forms to create art has been a constant challenge for any artist, whatever their field. At the end of the 20-century the concept that art can explore any field or subject, create a vision that is somehow technological, is part of the evolving artistic world. In the last two decades, in the search for new terminologies, scientists and artists have used the expression "Holographic" as a synonym of evolution, but with different meanings. Artists are using it as a new form of art call "Holo Art"; scientists see it as a "new" science technique where light takes an important part in the process, and can be used in various aspects of daily life, such as, security and medicine. This paper will explore artists who take the challenge of combining their art with new technologies and how they are viewed in a world where the question of 'what is and what isn't art' is very debatable. Other questions that will be explored are 'How can these techniques be useful to artists?' and 'How do artists challenge themselves to analyse the pros and cons of the results that can be obtained?'

  5. Dreams and imaginative processes in American and Balinese artists.

    Science.gov (United States)

    Gaines, R; Price-Williams, D

    1990-06-01

    A study is presented comparing the imaginative modes of American and Balinese artists. Strict survey comparison has not been possible owing to the lack of certain artistic types in the comparative culture and smallness of sample. By using an interview approach, a paradigmatic difference between the artistic members of the two cultures can be demonstrated. In American artists there is a more individualistic approach to creative imagery, with a stronger reliance on their dreams. In Balinese artists the creative endeavor is more collective, depending on more conscious imagery drawn from myths and common beliefs. The difference is correlated with the philosophical and cultural settings of each society in which the artist is embedded. Exemplar statements from interviews are presented to illustrate and support these propositions. Finally, it has been suggested that creative imagery should also be viewed in the perspective of differing concepts of self in the two societies.

    A real time reactor system analysis code ARTIST, based on drift flux model has been developed to investigate the transient system behavior under low pressure, low flow and low power conditions with noncondensable gas present in the system. The governing equations of the ARTIST code consist of three mass continuity equations (steam, liquid and noncondensables), two energy equations (steam and mixture) and one mixture equation constituted with the drift flux model. The drift flux model of ARTIST has been validated against the THETIS experimental data by comparing the void distribution in the system. Especially, the calculated void fraction by Chexal-Lellouche void fraction correlation at low pressure and low flow, is better than the results of both the homogeneous model of TASS code and the two-fluid model of RELAP5/MOD3 code. When noncondensable gas exists, thermal-hydraulic state solution scheme and the calculation methods of the partial derivatives are developed. Numerical consistency and convergence was tested with the one volume problems and the manometric oscillation was assessed to examine the calculation methods of the partial derivatives. Calculated thermal-hydraulic state for each test shows the consistent and expected behaviour. In order to evaluate the ARTIST code capability in predicting the two phase thermal-hydraulic phenomena of the loss of RHR accident during midloop operation, BETHSY test 6.9d is simulated. From the results, it is judged that the reflux condensation model and the critical flow model for the noncondensable gas are necessary to correctly predict the thermal-hydraulic behaviour. Finally, the verification run was performed without the drift flux model and the noncondensable gas model for the postulated accidents of the real plants. The ARTIST code well reproduces the parametric trends which are calculated by TASS code. Therefore, the integrity of ARTIST code was verified. 35 refs., 70 figs., 3 tabs. (Author)

  7. Traveling Artists in America: Visions and Views

    Directory of Open Access Journals (Sweden)

    Diener, Pablo

    2012-12-01

    Full Text Available Visual registers of Latin America acquired new characteristics at the dawning of the 19th century. Alongside the pointedly secular practice of the scientific Enlightenment, naturalistic in character, there emerged an artistic current that produced images with a strong subjective quality. This American iconography of the 19th century was the work of traveling artists. In the exercise of their work, painters and drawers were led through modern esthetical premises that proposed an amalgam of artistic activity and the production of scientific knowledge. This article intends to venture into that genre of the arts based on a study of the theoretical context that sustains it, observing the range of themes it covered.

    Los registros visuales de la América ibérica adquirieron un perfil nuevo con los albores del siglo XIX. Paralelamente a la práctica más que secular de la ilustración científica de carácter naturalista surgió una vertiente artística que produjo un tipo de imágenes con una fuerte carga subjetiva. Esa iconografía americana decimonónica fue obra de los artistas viajeros. En el ejercicio de su tarea, pintores y dibujantes fueron conducidos por premisas estéticas modernas, que proponían una amalgama del quehacer artístico con la producción de conocimiento científico. Este artículo propone una incursión en ese género de las bellas artes a partir de un estudio del contexto teórico que la sustenta, observando el abanico temático que abarcó.

    2013-04-01

    We discuss how the psycho-historical framework can be profitably applied to artistic production, facilitating a synthesis of perception-based and knowledge-based perspectives on realistic observational drawing. We note that artists' technical knowledge itself constitutes a major component of an artwork's historical context, and that links between artistic practice and psychological theory may yet yield conclusions in line with universalist perspectives.

    The deep ocean is to most of us a place unknown. Few of us experience the sea far from shore, fewer still dive to the seafloor at great depths. When scientists report on the outcome of deep-ocean exploration, their technical prose captures facts and insights, but fails to capture the emotional power of place and process. Through batik, watercolor illustrations, music, digital art, cartoon, and experimental video, six artists have created a portfolio of work that communicates the human experience of the deep ocean.

  11. Alfred Drury: The Artist as Curator

    Directory of Open Access Journals (Sweden)

    Ben Thomas

    2016-06-01

    Full Text Available This article presents a series of reflections on the experience of curating the exhibition ‘Alfred Drury and the New Sculpture’ in 2013. In particular, it charts the evolution of the design of the exhibition, notably its central tableau based on a photograph of the sculptor Alfred Drury’s studio in 1900. This photograph records a display of Drury’s works for visiting Australian patrons, and could be said to record evidence of the artist curating his own work. The legitimacy of deriving a curatorial approach from this photographic evidence is discussed, along with the broader problem of ‘historicizing’ approaches to curating.

  12. Artist's concept of Antimatter propulsion system

    Science.gov (United States)

    1999-01-01

    This is an artist's rendition of an antimatter propulsion system. Matter - antimatter arnihilation offers the highest possible physical energy density of any known reaction substance. It is about 10 billion times more powerful than that of chemical engergy such as hydrogen and oxygen combustion. Antimatter would be the perfect rocket fuel, but the problem is that the basic component of antimatter, antiprotons, doesn't exist in nature and has to manufactured. The process of antimatter development is on-going and making some strides, but production of this as a propulsion system is far into the future.

    Hamilton, G M; Meeuwisse, W H; Emery, C A; Shrier, I

    2012-06-01

    A secondary data analysis of a prospective cohort study was conducted to explore how different definitions of injury affect the results of risk factor analyses. Modern circus artists (n=1281) were followed for 828,547 performances over a period of 49 months (2004-2008). A univariate risk factor analysis (age, sex, nationality, artist role) estimating incidence rate ratios (IRR) with 95% confidence intervals (95% CI) was conducted using three injury definitions: (1) medical attention injuries, (2) time-loss injuries resulting in ≥1 missed performances (TL-1) and (3) time-loss injuries resulting in >15 missed performances (TL-15). Results of the risk factor analysis were dependent on the injury definition. Sex (females to male; IRR=1.13, 95% CI; 1.02-1.25) and age over 30 (30 years; IRR=1.37, 95% CI; 1.07-1.79) were risk factors for medical attention injuries only. Risk of injury for Europeans compared with North Americans was higher for TL-1 and TL-15 injuries compared with medical attention injuries. Finally, non-sudden load artists (low-impact acts) were less likely than sudden load artists (high-impact acts) to have TL-1 injuries, but the risk of medical attention injuries was similar. The choice of injury definition can have effects on the magnitude and direction of risk factor analyses. © 2010 John Wiley & Sons A/S.

    Full Text Available URB is a research project designed to collect and store raw data from soundscapes analysis. This paper presents a survey about using URB based on the analysis of work developed by several artists, focusing on the description of their creative process and outcome. By comparing the processes and statements of each artists, the authors identified diverse systematic approaches to reinterpreting raw data provided by urban soundscapes, raising questions about the artistic outcomes vs original sound sources. Furthermore, some considerations are inferred about the artistic relevance of using this process in the creation process.

  17. Visually assessed colour overlay features in shear-wave elastography for breast masses: quantification and diagnostic performance.

    Science.gov (United States)

    Gweon, Hye Mi; Youk, Ji Hyun; Son, Eun Ju; Kim, Jeong-Ah

    2013-03-01

    To determine whether colour overlay features can be quantified by the standard deviation (SD) of the elasticity measured in shear-wave elastography (SWE) and to evaluate the diagnostic performance for breast masses. One hundred thirty-three breast lesions in 119 consecutive women who underwent SWE before US-guided core needle biopsy or surgical excision were analysed. SWE colour overlay features were assessed using two different colour overlay pattern classifications. Quantitative SD of the elasticity value was measured with the region of interest including the whole breast lesion. For the four-colour overlay pattern, the area under the ROC curve (Az) was 0.947; with a cutoff point between pattern 2 and 3, sensitivity and specificity were 94.4 % and 81.4 %. According to the homogeneity of the elasticity, the Az was 0.887; with a cutoff point between reasonably homogeneous and heterogeneous, sensitivity and specificity were 86.1 % and 82.5 %. For the SD of the elasticity, the Az was 0.944; with a cutoff point of 12.1, sensitivity and specificity were 88.9 % and 89.7 %. The colour overlay features showed significant correlations with the quantitative SD of the elasticity (P < 0.001). The colour overlay features and the SD of the elasticity in SWE showed excellent diagnostic performance and showed good correlations between them.

  18. Evaluating National Environmental Sustainability: Performance Measures and Influential Factors for OECD-Member Countries featuring Canadian Performance and Policy Implications

    Science.gov (United States)

    Calbick, Kenneth S.

    This research reviews five studies that evaluate national environmental sustainability with composite indices; performs uncertainty and sensitivity analyses of techniques for building a composite index; completes principal components factor analysis to help build subindices measuring waste and pollution, sustainable energy, sustainable food, nature conservation, and sustainable cities (Due to its current importance, the greenhouse gases (GHG) indicator is included individually as another policy measure.); analyses factors that seem to influence performance: climate, population growth, population density, economic output, technological development, industrial structure, energy prices, environmental governance, pollution abatement and control expenditures, and environmental pricing; and explores Canadian policy implications of the results. The techniques to build composite indices include performance indicator selection, missing data treatment, normalisation technique, scale-effect adjustments, weights, and aggregation method. Scale-effect adjustments and normalisation method are significant sources of uncertainty inducing 68% of the observed variation in a country's final rank at the 95% level of confidence. Choice of indicators also introduces substantial variation as well. To compensate for this variation, the current study recommends that a composite index should always be analysed with other policy subindices and individual indicators. Moreover, the connection between population and consumption indicates that per capita scale-effect adjustments should be used for certain indicators. Rather than ranking normalisation, studies should use a method that retains information from the raw indicator values. Multiple regression and cluster analyses indicate economic output, environmental governance, and energy prices are major influential factors, with energy prices the most important. It is statistically significant for five out of seven performance measures at the 95

    2018-03-01

    The theoretical positioning accuracy of multilateration (MLAT) with the time difference of arrival (TDOA) algorithm is very high. However, there are some problems in practical applications. Here we analyze the location performance of the time sum of arrival (TSOA) algorithm from the root mean square error ( RMSE) and geometric dilution of precision (GDOP) in additive white Gaussian noise (AWGN) environment. The TSOA localization model is constructed. Using it, the distribution of location ambiguity region is presented with 4-base stations. And then, the location performance analysis is started from the 4-base stations with calculating the RMSE and GDOP variation. Subsequently, when the location parameters are changed in number of base stations, base station layout and so on, the performance changing patterns of the TSOA location algorithm are shown. So, the TSOA location characteristics and performance are revealed. From the RMSE and GDOP state changing trend, the anti-noise performance and robustness of the TSOA localization algorithm are proved. The TSOA anti-noise performance will be used for reducing the blind-zone and the false location rate of MLAT systems.

    Full Text Available Abstract The purpose of this study was to investigate the injuries prevalence in men elite artistic gymnasts. Twenty Brazilian senior gymnasts, aged 23.1 ± 6.5 years, 13.9 ± 5.0 years of practice and 36.5 ± 4.7 hours per week training, participated in this study. The athletes answered a morbidity questionnaire, formulated according to studies from the literature, for information on the injuries’ characteristics and circumstances. Information about the injury circumstances (gymnastic apparatus, overload training and physical exercises, the anatomic site injured, the affect biological tissue and the return to training after injury treatment were evaluated. Data were analyzed by descriptive statistics, absolute and relative frequencies. The training overload, and floor, pommel horse and vault were the events that presented higher injuries frequency. In relation to anatomic site, ankle, hands/fingers and shoulder were the most cited regions. The ligament, bone and articular capsule were the most affected biological tissues. In relation to gymnasts’ return to their sports activities, 56% of them reported a better condition at return, 33% reported to have returned at the same fitness level and 10% indicated that they were in a worse condition when they returned to the sports activities. The men’s artistic gymnastics injuries are related to the mechanical demands of this sport. The analysis of risk factors helps in understanding the injuries mechanisms in gymnastics, and provides relevant information that can assist in effective prevention strategies.

    Full Text Available Purpose: The aim of the study was to evaluate the somatic development and comprehensive physical fitness of artistic gymnasts aged 7-10 years. Materials and methods: Gymnasts (n = 307, split up into four age groups performed eight Eurofit tests. The results were evaluated in points according to the development standards prepared in scale T for the Polish girls population. Results : The gymnasts obtained the highest growth rate in balance test - FLB (13 points, arm and shoulder muscular endurance test - BAH (7 points and speed of the upper limb movement test - PLT (4 points out of eight physical fitness tests. Conclusions. High and very high level of performance in the six Eurofit tests and increased total number of points in the subsequent age groups of artistic gymnasts proved high effectiveness of training in shaping the key components of a comprehensive physical fitness in artistic gymnastics - balance, strength, endurance, speed and flexibility. Relatively little progress in isometric hand strength (HGR and standing broad jump (SBJ suggests a significant influence of genetic factors on the level of these abilities. The results provide an objective information useful in optimizing control system of training effects in comprehensive physical fitness and optimization of artistic gymnasts training at the comprehensive stage of sports training.

    Dynamic contrast-enhanced breast magnetic resonance imaging (DCE-MRI) has been used increasingly in breast cancer diagnosis and assessment of cancer treatment efficacy. In this study, we applied a computer-aided detection (CAD) scheme to automatically segment breast regions depicting on MR images and used the kinetic image features computed from the global breast MR images acquired before neoadjuvant chemotherapy to build a new quantitative model to predict response of the breast cancer patients to the chemotherapy. To assess performance and robustness of this new prediction model, an image dataset involving breast MR images acquired from 151 cancer patients before undergoing neoadjuvant chemotherapy was retrospectively assembled and used. Among them, 63 patients had "complete response" (CR) to chemotherapy in which the enhanced contrast levels inside the tumor volume (pre-treatment) was reduced to the level as the normal enhanced background parenchymal tissues (post-treatment), while 88 patients had "partially response" (PR) in which the high contrast enhancement remain in the tumor regions after treatment. We performed the studies to analyze the correlation among the 22 global kinetic image features and then select a set of 4 optimal features. Applying an artificial neural network trained with the fusion of these 4 kinetic image features, the prediction model yielded an area under ROC curve (AUC) of 0.83+/-0.04. This study demonstrated that by avoiding tumor segmentation, which is often difficult and unreliable, fusion of kinetic image features computed from global breast MR images without tumor segmentation can also generate a useful clinical marker in predicting efficacy of chemotherapy.

    LAMPF is a multi-purpose high-intensity meson factory capable of producing a 1 mA beam of 800-MeV protons. The three target cells and the beam stop facilities in the high intensity area have many special design features that are required for operation in the presence of high heat loads and intense radiation fields where accessibility is extremely limited. Reliable targets, beam windows, beam stops, beam transport and diagnostic components, vacuum enclosures, and auxiliary systems have been developed. Sophisticated remote-handling systems are employed for maintenance. Complex protection systems have been developed to guard against damage caused by errant beam. Beam availability approaching 90% has been achieved at currents of 600 to 700 μA. A new facility for direct proton and neutron radiation effects studies will be installed in 1985. The new facility will provide an integrated spallation neutron flux of up to 5 x 10 17 m -2 s -1 and will anable proton irradiation studies in the primary beam

He has a sharp eye and a sensitive spirit and creative temprement and by inventing new images shows the creativity and imagination in various arenas and attempts in the way of literary strength and creating personal style and this point more than anything else must be done by presenting images and newness. Perhaps in the sixth century, and especially in Azerbaijani school, more than other periods, poets have been looking for creating innovative style in eloquence. Their major attempts were mainly in imaging, it was a wide field that they have competed and it is natural that in this illustration the alphabet letters would be very helpful. Khaghani poetry as one of the greatest poets of this school has the perfect poetrical book of painting and meaning, and delicated pattern in new and different scientific, cultural and religious paintings and letters are a broad range of elements that put a new field in front of the poet and he is aware of the potential features of the letters and also the new images and the artistic creativity.This paper shows descriptive - analytical study of various aspects of Khaghani’s poetry and frequency of letters in the alphabet, authentic images based on alphabet, taken at different pseudo relevance of poetry in the context of multiple semantic and literal characters, making figures of speech based on literary characters, images and characters and the sense of connection . . . which has been shown in his poetry.Letter has double and even multiple uses in Khaghani poetic works (divan and more than the construction of words which is the real and common sense that is used as an artistic.

    Despite a body of research on teams in other fields relatively little is known about measuring teamwork in healthcare. The aim of this study is to characterize the qualitative dimensions of team performance during cardiac resuscitation that results in good and bad outcomes. We studied each team's adherence to Advanced Cardiac Life Support (ACLS) protocol for ventricular fibrillation/tachycardia and identified team behaviors during simulated critical events that affected their performance. The process was captured by a developed task checklist and a validated team work coding system. Results suggest that deviation from the sequence suggested by the ACLS protocol had no impact on the outcome as the successful team deviated more from this sequence than the unsuccessful team. It isn't the deviation from the protocol per se that appears to be important, but how the leadership flexibly adapts to the situational changes with deviations is the crucial factor in team competency.

    Full Text Available We sought to develop a standardized curriculum capable of assessing key competencies in Interventional Neuroradiology by the use of models and simulators in an objective, quantitative, and efficient way. In this evaluation we analyzed the associations between the practical experience, theoretical knowledge, and the skills lab performance of interventionalists.We evaluated the endovascular skills of 26 participants of the Advanced Course in Endovascular Interventional Neuroradiology of the European Society of Neuroradiology with a set of three tasks (aneurysm coiling and thrombectomy in a virtual simulator and placement of an intra-aneurysmal flow disruptor in a flow model. Practical experience was assessed by a survey. Participants completed a written and oral examination to evaluate theoretical knowledge. Bivariate and multivariate analyses were performed.In multivariate analysis knowledge of materials and techniques in Interventional Neuroradiology was moderately associated with skills in aneurysm coiling and thrombectomy. Experience in mechanical thrombectomy was moderately associated with thrombectomy skills, while age was negatively associated with thrombectomy skills. We found no significant association between age, sex, or work experience and skills in aneurysm coiling.Our study gives an example of how an integrated curriculum for reasonable and cost-effective assessment of key competences of an interventional neuroradiologist could look. In addition to traditional assessment of theoretical knowledge practical skills are measured by the use of endovascular simulators yielding objective, quantitative, and constructive data for the evaluation of the current performance status of participants as well as the evolution of their technical competency over time.

    Students' perceptions of their learning environment influence the quality of outcomes they achieve. Learning dental operative techniques in a simulated clinic environment is characterised by reciprocal interactions between skills training, staff- and student-related factors. However, few studies have examined how students perceive their operative learning environments and whether there is a relationship between their perceptions and subsequent performance. Therefore, this study aimed to clarify which learning activities and interactions students perceived as supporting their operative skills learning and to examine relationships with their outcomes. Longitudinal data about examples of operative laboratory sessions that were perceived as effective or ineffective for learning were collected twice a semester, using written critical incidents and interviews. Emergent themes from these data were identified using thematic analysis. Associations between perceptions of learning effectiveness and performance were analysed using chi-square tests. Students indicated that an effective learning environment involved interactions with tutors and peers. This included tutors arranging group discussions to clarify processes and outcomes, providing demonstrations and constructive feedback. Feedback focused on mistakes, and not improvement, was reported as being ineffective for learning. However, there was no significant association between students' perceptions of the effectiveness of their learning experiences and subsequent performance. It was clear that learning in an operative technique setting involved various factors related not only to social interactions and observational aspects of learning but also to cognitive, motivational and affective processes. Consistent with studies that have demonstrated complex interactions between students, their learning environment and outcomes, other factors need investigation. © 2014 John Wiley & Sons A/S.

    Scenario development has two primary purposes in the design and documentation of postclosure performance assessments in a regulatory setting. First, scenario development ensures a sufficiently comprehensive consideration of the possible future states of the system. Second, scenario development identifies the important scenarios that must be considered in quantitative analyses of the total system performance assessment (TSPA). To ensure clear documentation of the treatment of potentially relevant future states of the system in the Yucca Mountain license application (LA), the US Department of Energy (DOE) has chosen to adopt a scenario development process based on the methodology developed by Cranwell et al. (1990) for the US Nuclear Regulatory Commission (NRC). Although the process, described below, has been modified somewhat as a result of experience gained in the last decade, the underlying methodology is consistent with that outlined by the DOE in the 1988 Site Characterization Plan for the Yucca Mountain Project (YMP) (U.S. DOE, 1988). The approach is fundamentally the same as that used in many performance assessments, including the most recent analysis of the Yucca Mountain repository by the NRC (Wescott et al., 1995). The approach has also been used by the DOE for the Waste Isolation Pilot Plant (WIPP) (U.S. DOE, 1996), by the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-Operation and Development (OECD), and by other radioactive waste programs internationally. Section 2.0 of this report describes the scenario development process. Steps in the process are described in Section 2.1, and terms introduced in this section are defined in Section 2.2.

    It is often assumed (explicitly or implicitly) that animals select habitat features to maximize fitness. However, there is often a mismatch between preferred habitats and indices of individual and population measures of performance. We examined the influence of fine-scale habitat selection on the overall population performance of the White-tailed Ptarmigan (Lagopus leucura), an alpine specialist, in two subdivided populations whose habitat patches are configured differently. The central region of Vancouver Island, Canada, has more continuous and larger habitat patches than the southern region. In 2003 and 2004, using paired logistic regression between used (n = 176) and available (n = 324) sites, we identified food availability, distance to standing water, and predator cover as preferred habitat components . We then quantified variation in population performance in the two regions in terms of sex ratio, age structure (n = 182 adults and yearlings), and reproductive success (n = 98 females) on the basis of 8 years of data (1995-1999, 2002-2004). Region strongly influenced females' breeding success, which, unsuccessful hens included, was consistently higher in the central region (n = 77 females) of the island than in the south (n = 21 females, P = 0.01). The central region also had a much higher proportion of successful hens (87%) than did the south (55%, P < 0.001). In light of our findings, we suggest that population performance is influenced by a combination of fine-scale habitat features and coarse-scale habitat configuration. ??

    Full Text Available In this paper, a novel feature extraction approach which can be referred to as moving window function capturing (MWFC has been proposed to analyze signals of an electronic nose (E-nose used for detecting types of infectious pathogens in rat wounds. Meanwhile, a quantum-behaved particle swarm optimization (QPSO algorithm is implemented in conjunction with support vector machine (SVM for realizing a synchronization optimization of the sensor array and SVM model parameters. The results prove the efficacy of the proposed method for E-nose feature extraction, which can lead to a higher classification accuracy rate compared to other established techniques. Meanwhile it is interesting to note that different classification results can be obtained by changing the types, widths or positions of windows. By selecting the optimum window function for the sensor response, the performance of an E-nose can be enhanced.

    To evaluate the diagnostic performance of ultrasound and to determine which ultrasound findings are useful to differentiate appendicitis from non-appendicitis in patients who underwent ultrasound re-evaluation owing to equivocal CT features of acute appendicitis. 62 patients who underwent CT examinations for suspected appendicitis followed by ultrasound re-evaluation owing to equivocal CT findings were included. Equivocal CT findings were considered based on the presence of only one or two findings among the CT criteria, and ultrasound re-evaluation was done based on a predefined structured report form. The diagnostic performance of ultrasound and independent variables to discriminate appendicitis from non-appendicitis were assessed. There were 27 patients in the appendicitis group. The overall diagnostic performance of ultrasound re-evaluation was sensitivity of 96.3%, specificity of 91.2% and accuracy of 91.9%. In terms of the performance of individual ultrasound findings, probe-induced tenderness showed the highest accuracy (86.7%) with sensitivity of 74% and specificity of 97%, followed by non-compressibility (accuracy 71.7%, sensitivity 85.2% and specificity 60.6%). The independent ultrasound findings for discriminating appendicitis were non-compressibility (p = 0.002) and increased flow on the appendiceal wall (p = 0.001). Ultrasound re-evaluation can be used to improve diagnostic accuracy in cases with equivocal CT features for diagnosing appendicitis. The presence of non-compressibility and increased vascular flow on the appendix wall are useful ultrasound findings to discriminate appendicitis from non-appendicitis. Advances in knowledge: Ultrasound re-evaluation is useful to discriminate appendicitis from non-appendicitis when CT features are inconclusive.

    Full Text Available This article explores the two series of visits to the artist's studio that appeared in the famed French illustrated magazine L'Illustration in the 1850s and in 1886. An in-depth examination of both the texts and images reveals the verbal and visual tropes used to characterize the artists and their spaces, linking these to broader notions of "the artist" – his moral characteristics, behaviors, and artistic practice – as well as to the politics of the art world and the (bourgeois ideology of L'Illustration. The aim is to uncover not only the language but also the mechanics of the "mediatization" of the image of the artist in this crucial period.

    To explore the relationship between potential psychological risk factors and injury risk in circus artists. Historical cohort study. Cirque du Soleil training programme. Forty-seven circus artists training to become Cirque du Soleil artists. Artists completed the validated REST-Q questionnaire (19 domains) during their first 2 weeks of training. Injury risk ratio. Of the five a priori exposures of interest, injury, emotional exhaustion, self-efficacy and fatigue were associated with an increase in injury risk (risk ratios between 1.8 and 2.8), but Conflicts/Pressure was not (risk ratio=0.8). Of the several specific psychological aspects that are considered risk factors for injury, low self-efficacy had the strongest relationship. Most of the strong psychological risk factors for injuries previously identified in athletes also appear to be risk factors in circus artists.

  8. Nadine Gordimer: The White Artist as A Sport of Nature

    Directory of Open Access Journals (Sweden)

    Barbara Temple-Thurston

    1991-01-01

    Full Text Available This article applies principles of new historicism to show that A Sport of Nature can be read as Gordimer's attempt to persuade South African artists to reject mere protest art and to shift art beyond the trap of oppositional forces in South Africa's history today. The text calls instead—via fiction and the imagination—for a new post-apartheid art that will generate creative possibilities for a future South Africa. Gordimer's protagonist, Hillela Capran, is read as a metaphor for the white South African artist who, like Hillela, struggles for an authentic identity and meaningful role in the evolving history of South Africa. This paper asserts that A Sport of Nature boldly proposes the mutation necessary for the South African artist and people to resolve the political, personal, or artistic fragmentation, beckoning other artists along the path. Hope of its assured success, however, remains as elusive and unpredictable as any "sport of nature" must be.

    Full Text Available This paper presents reflections on initial education of Art teachers, prioritized knowledge in the curriculum and demands of school artistic practice, resulting from research performed with teachers from Parana State Public Network (Brazil, especially graduates with Music Teaching Degrees. Questions on education in Teaching Degrees are addressed - musical practice, pedagogical studies, training and relationship with the school, strengths and weaknesses of the curriculum and school artistic practice - planning, content and methodologies, demands of students and managers for Art classes. The purpose of this analysis was to collate education by teachers whilst adhering to school‟s demands, to discuss the challenges of teaching work in Art/Music in relation to different determinants that constitute it. Among other problems, data shows the difficulties for teachers in planning from the determinations of the Diretrizes Curriculares Estaduais - DCE (2009 (State Curricular Guidelines, which proposes actions within all artistic fields Music, Theater, Dance and Visual Arts and the effective practice with a view to the specific education in Music and Visual Arts Teaching Degrees. The resulting answers enabled problematization of the relationship between theory and practice of education/work of these teachers and pointed to the contradiction between artistic education as a pragmatic activity and the potentiality of aesthetic and humanizing education proclaimed by the Marxist perspective.

  11. General relativistic radiative transfer code in rotating black hole space-time: ARTIST

    Science.gov (United States)

    Takahashi, Rohta; Umemura, Masayuki

    2017-02-01

    We present a general relativistic radiative transfer code, ARTIST (Authentic Radiative Transfer In Space-Time), that is a perfectly causal scheme to pursue the propagation of radiation with absorption and scattering around a Kerr black hole. The code explicitly solves the invariant radiation intensity along null geodesics in the Kerr-Schild coordinates, and therefore properly includes light bending, Doppler boosting, frame dragging, and gravitational redshifts. The notable aspect of ARTIST is that it conserves the radiative energy with high accuracy, and is not subject to the numerical diffusion, since the transfer is solved on long characteristics along null geodesics. We first solve the wavefront propagation around a Kerr black hole that was originally explored by Hanni. This demonstrates repeated wavefront collisions, light bending, and causal propagation of radiation with the speed of light. We show that the decay rate of the total energy of wavefronts near a black hole is determined solely by the black hole spin in late phases, in agreement with analytic expectations. As a result, the ARTIST turns out to correctly solve the general relativistic radiation fields until late phases as t ˜ 90 M. We also explore the effects of absorption and scattering, and apply this code for a photon wall problem and an orbiting hotspot problem. All the simulations in this study are performed in the equatorial plane around a Kerr black hole. The ARTIST is the first step to realize the general relativistic radiation hydrodynamics.

    2016-02-01

    Full Text Available Michael Haneke's (2012 film Amour is used as a point of departure for discussing a spectrum of artistic representations of "old love," a phenomenon that is still little understood. While most critics have focused on euthanasia when referring to the film's dramatic climax, its late-life perspective of love has been marginalized. Analyzing Amour, as well as other recent cinematic and poetic texts, we challenge the widespread midlife and ageist perception of "April love," contrasting it with different views from within old love. Our reading of Amour illustrates the effects of intense, all-encompassing, and sealed intimacy in advanced old age and sheds light on potential consequences it may have on the decisions and lives of the people involved. We conclude by discussing how certain forms of love, seen from within, unfold in tandem with age or life phases that affect the pace, emotional, and interpersonal nature of the partnership.

    Purpose: Segmentation quality can affect quantitative image feature analysis. The objective of this study is to examine the relationship between computed tomography (CT) image quality, segmentation performance, and quantitative image feature analysis. Methods: A total of 90 pathology proven breast lesions in 87 dedicated breast CT images were considered. An iterative image reconstruction (IIR) algorithm was used to obtain CT images with different quality. With different combinations of 4 variables in the algorithm, this study obtained a total of 28 different qualities of CT images. Two imaging tasks/objectives were considered: 1) segmentation and 2) classification of the lesion as benign or malignant. Twenty-three image features were extracted after segmentation using a semi-automated algorithm and 5 of them were selected via a feature selection technique. Logistic regression was trained and tested using leave-one-out-cross-validation and its area under the ROC curve (AUC) was recorded. The standard deviation of a homogeneous portion and the gradient of a parenchymal portion of an example breast were used as an estimate of image noise and sharpness. The DICE coefficient was computed using a radiologist’s drawing on the lesion. Mean DICE and AUC were used as performance metrics for each of the 28 reconstructions. The relationship between segmentation and classification performance under different reconstructions were compared. Distributions (median, 95% confidence interval) of DICE and AUC for each reconstruction were also compared. Results: Moderate correlation (Pearson’s rho = 0.43, p-value = 0.02) between DICE and AUC values was found. However, the variation between DICE and AUC values for each reconstruction increased as the image sharpness increased. There was a combination of IIR parameters that resulted in the best segmentation with the worst classification performance. Conclusion: There are certain images that yield better segmentation or classification

    As of the end of Dec. 1999, Korea's total nuclear power capacity reached 13,716 MWe with 16 units in operation and 4 units under construction. In addition, as part of the national long-term R and D programme launched in 1992, the Korean Next Generation Reactor (KNGR) is being developed to meet the electricity demands in the years to come and is expected to be safer and more economically competitive than any other conventional electric power sources in Korea. The KNGR project has successfully completed its second phase and is now on the third phase. In Phase III of the KNGR design development project, KNGR aims at reinforcing the economic competitiveness while maintaining safety goals. To achieve these objectives, the design options studied and the design requirements set up in the first phase are pursued while the second phase are being reviewed. This paper summarizes such efforts for design improvement in terms of performance and economic viability along with the status of nuclear power generation in Korea, focusing on KNGR currently.

    Full Text Available The objective of this experiment was to evaluate the effect of 2 feeding systems and 5 breeding groups on the growth performance, biometric features, and stomach morphology of feedlot goat kids. The experiment utilized gender as a randomized blocking factor in a 5 × 2 factorial scheme. The study goats were from the Alpine, Anglo-Nubian, 1/2 Boer x Alpine, 3/4 Boer x Alpine, and 7/8 Boer x Alpine breeds. Half of the goats were fed an experimental diet, whereas the other half were given the same diet supplemented with 1.5 L milk daily. The kids were slaughtered after they attained 30 kg body weight. The 1/2 Boer x Alpine goats showed superior growth performance because they exhibiting considerable heterosis. These animals are especially easy to use given that there is no need to maintain cross-bred females (½ Boer x Alpine e ¾ Boer x Alpine in the flock. Using milk in the feed the animals does not adversely affect growth performance or biometric features. Moreover, it helps to reduce the total weight of the stomach and leads to a 51.39% savings on feed. Dietary supplementation of milk in goat feed is recommended so long as there is excess milk available on the property.

    2005-11-01

    Full Text Available We use a sample of 964 executive directors representing 354 Singapore publicly listed firms to examine linkage between firm performance and cash-based bonus payments. As a pooled OLS regression model may hide different models that characterize subsets of observations we use latent class analysis to further examine the data and to identify more specifically the influence of corporate governance features. Our latent class analysis results indicate that remuneration committees with members having their interests better aligned with shareholders (such as presence of a significant owner appear more likely to consider the incremental value of tying executive director compensation to intellectual capital performance. Remuneration committees with a lower risk of influence from managerial power were also found to be more likely to support a compensation linkage for executive directors to intellectual capital performance. The influence of the remuneration committee features is evident for both entrepreneurial and traditional firms. Overall, our findings are consistent with both the optimal-contract pricing and managerial power views of executive compensation setting.

  18. Adaptive cellular structures and devices with internal features for enhanced structural performance

    Science.gov (United States)

    Pontecorvo, Michael Eugene

    This dissertation aims to develop a family of cellular and repeatable devices that exhibit a variety of force-displacement behaviors. It is envisioned that these cellular structures might be used either as stand-alone elements, or combined and repeated to create multiple types of structures (i.e. buildings, ship hulls, vehicle subfloors, etc.) with the ability to passively or actively perform multiple functions (harmonic energy dissipation, impact mitigation, modulus change) over a range of loading types, amplitudes, and frequencies. To accomplish this goal, this work combines repeatable structural frameworks, such as that provided by a hexagonal cellular structure, with internal structural elements such as springs, viscous dampers, buckling plates, bi-stable von Mises trusses (VMTs), and pneumatic artificial muscles (PAMs). The repeatable framework serves to position damping and load carrying elements throughout the structure, and the configuration of the internal elements allow each cell to be tuned to exhibit a desired force-displacement response. Therefore, gradient structures or structures with variable load paths can be created for an optimal global response to a range of loads. This dissertation focuses on the development of cellular structures for three functions: combined load-carrying capability with harmonic energy dissipation, impact mitigation, and cell modulus variation. One or more conceptual designs are presented for devices that can perform each of these functions, and both experimental measurements and simulations are used to gain a fundamental understanding of each device. Chapter 2 begins with a presentation of a VMT model that is the basis for many of the elements. The equations of motion for the VMT are derived and the static and dynamic behavior of the VMT are discussed in detail. Next, two metrics for the energy dissipation of the VMT - hysteresis loop area and loss factor - are presented. The responses of the VMT to harmonic displacement

    The (18) modular coils for the National Compact Stellarator Experiment (NCSX) are joined at assembly by interfaces to form a toroidal shell which serves as the structural backbone of the device. There are six each of three coil types (A, B, and C); consequently, there are 4 distinct interface designs (A-A, A-B, B-C, C-C). This paper describes the performance evaluations and analyses used in the development of these critical interfaces. Initial analyses indicated that the baseline interface designs did not provide adequate shear capability along the inner (unbolted) legs between the modular coils and did not adequately address assembly tolerance requirements. Consequently a design effort was undertaken to develop interfaces with adequate shear capability and which would facilitate the achievement of assembly tolerances. Analyses indicated that a friction coefficient of 0.3 is necessary for 'no-slip' joints with a preload value of ∼320 kN in the outboard regions. Two types of compatible segmented friction shims were developed to meet the friction requirement. One type uses alumina coated stainless steel shims and the other uses G-10/ stainless steel/ G-10 'sandwich shims.' Analyses indicated that the time constant requirements for induced currents in the shell could still be achieved with welds along all the inner (unbolted) legs except at the C-C interface. Consequently, welded interfaces utilizing alternating MIG fillet welds on each end of shims between coil castings were developed to react the shear loads. This configuration minimizes distortion since it avoids direct weld shrinkage stress across the interfaces. Analyses indicates that a 12.7 mm fillet weld has adequate shear capability, with average stress through the welds of 90-125 MPa, compared to a static limit of 217 MPa. Custom sized compression pucks located in the middle of the welded shims react the compressive loads and have average stresses less than 137 MPa. Fatigue acceptability of the welded

    The aims of this study were to investigate the experience of bullying in a representative sample of Jordanian schoolchildren in Amman, to look at its effect on school attendance and perception of academic performance, and to look at the contribution of general physical and dentofacial features to this phenomenon. This was a cross-sectional study in which a representative sample of sixth-grade students (11-12 years of age) from randomly selected schools was asked to complete questionnaires distributed in the classroom in the presence of the researchers. The final sample size was 920 children (470 girls, 450 boys). The prevalence of bullying was 47% (n = 433); significantly more boys reported being bullied than girls (P bullying reported playing truant from school and disliking school than those who were not bullied. Teeth were the number 1 feature targeted for bullying, followed by strength and weight. The 3 most commonly reported dentofacial features targeted by bullies were spacing between the teeth or missing teeth, shape or color of the teeth, and prominent maxillary anterior teeth. This study demonstrated a high prevalence of bullying in Jordanian schools, with many children experiencing bullying because of their dental or facial appearance.

  2. The Role of Interaction Patterns with Hybrid Electric Vehicle Eco-Features for Drivers' Eco-Driving Performance.

    Science.gov (United States)

    Arend, Matthias G; Franke, Thomas

    2017-03-01

    The objective of the present research was to understand drivers' interaction patterns with hybrid electric vehicles' (HEV) eco-features (electric propulsion, regenerative braking, neutral mode) and their relationship to fuel efficiency and driver characteristics (technical system knowledge, eco-driving motivation). Eco-driving (driving behaviors performed to achieve higher fuel efficiency) has the potential to reduce CO 2 emissions caused by road vehicles. Eco-driving in HEVs is particularly challenging due to the systems' dynamic energy flows. As a result, drivers are likely to show diverse eco-driving behaviors, depending on factors like knowledge and motivation. The eco-features represent an interface for the control of the systems' energy flows. A sample of 121 HEV drivers who had constantly logged their fuel consumption prior to the study participated in an online questionnaire. Drivers' interaction patterns with the eco-features were related to fuel efficiency. A common factor was identified in an exploratory factor analysis, characterizing the intensity of actively dealing with electric energy, which was also related to fuel efficiency. Driver characteristics were not related to this factor, yet they were significant predictors of fuel efficiency. From the perspective of user-energy interaction, the relationship of the aggregated factor to fuel efficiency emphasizes the central role of drivers' perception of and interaction with energy conversions in determining HEV eco-driving success. To arrive at an in-depth understanding of drivers' eco-driving behaviors that can guide interface design, authors of future research should be concerned with the psychological processes that underlie drivers' interaction patterns with eco-features.

Issues such as the "boundary" and "binding" problems were approached, as well as the challenge of creating visual metaphors for neural processes. One artist visualized the increasing transparency of the body as researchers introduce more and more invasive technologies.

  5. [The mentally ill artist--a historical retrospect].

    The painting of the mentally ill has fascinated artists and their public throughout the 20th century. Yet the psychologically as well as art-historically interesting topic can be traced back over a long period in the history of Western culture. Aristotle emphasizes that all men who create great works, such as artists, philosophers, poets and politicians, are prone to melancholy, that excess of black gall which is characteristic of artists and depressive. Although Plato distinguished between creative and clinical mania, the topos of "genius and madness" prevails up to our century. The cult of melancholy is taken up bei Marsilio Ficino and becomes fashionable among the artists of the 16th and 17th centuries. During the Romantic period of the early 19th century the psychologically unstable or even sick intellectual and artist becomes the focus of attention. Artistic madness is glorified in an almost mystical fashion. However, disillusionment was soon to follow. Schopenhauer, Lombroso and many physicians stress the close relationship between genius and madness. However, they judge madness to be merely morbid and negative. During the 20th century the artists of the avantgarde show much interest in psychoanalysis and in the art of the mentally ill. The rise of National Socialism brought about a drastic break in the appraisal of the art of the mentally ill, which today is an acknowledged factor in contemporary art.

    This study assessed physical performance in women's artistic gymnastics following three variable recovery periods. Participants included fifteen female gymnasts (mean age = 13.5 ± 1.1) who had competed at USA Gymnastics (USAG) levels 7 - 10 within at least one year prior to the study. Each testing session consisted of a warm-up followed by four muscular endurance tests and one explosive maximal test. Assessments included pull-ups, leg lifts, handstand push-ups, vertical jump, and push-ups. After the performance assessments, the participants completed a typical practice session. The performance measures were reassessed at the beginning of each of the recovery periods of 24, 48, and 72 hours in a counterbalanced design. Performance assessments were converted into Z-scores and then averaged for a composite session Z-score. The composite session Z-scores were compared to evaluate the recovery duration. Composite Z's were significantly lower (p=0.000), after the 24 (z=-1.10) and the 48 hour (z=-0.71) recovery periods compared to baseline (z=0.00). However, there was no difference in scores (p=1.00) between the baseline and 72 hours (z=0.004) recovery. Full recovery required 72 hours under the conditions of this study.

    Full Text Available The Internet provides new business opportunities for the music industry, especially for both independent artists and record companies. The reason of the latter is the great proliferation and growth of digital music platforms. However, contrary to statistics, artists have not been able to benefit of such opportunities in the expected manner. The academic development on this subject is in its beginnings especially with respect to the Colombian panorama, therefore for the first time in the literature, this paper draws some of the difficulties that the Colombian artists face in the world of the digital music.

    Despite the prominent loss of motor skills, artistic capacities remain preserved in Parkinson's disease (PD). Furthermore, artistic creativity may emerge in art-naïve PD patients treated with levodopa and dopamine agonists. The present review discusses reported PD patients who developed enhanced artistic skills under anti-Parkinsonian therapy and the course of this phenomenon in the clinical context. It is unclear whether creative drive is related to dopamine dysregulation, and the mechanisms remain speculative. The delineation of the particular constellation that enables this emergence in PD patients may shed light on the comprehension of the concept of creativity in general.

    The article tells about the formation of Russian design education in the XXth century. It focuses on the peculiar features and causes of its insufficient effectiveness in the historical context. It studies the dynamics of changes in the priorities related to the artistic and industrial education in Russia and the connection of these processes with socio-political transformations. The article identifies the role of constructivist artists in the formation and approbation of advanced design-engineering techniques. It emphasizes the interdisciplinary essence of the profession of a designer as a special kind of design activities, its organizing, consolidating and progressive origin in the sphere of industrial production and carrying out interdisciplinary studies. It discloses the essence of a new “engineer-artist” profession. It briefly describes the influence of the fundamental principle of design - projectivity, on engineering and design disciplines when the interaction of an artist, an engineer and an architect is achieved on the basis of design, arrangement and inventive art as well as production organization where science and technology form the basis for creative work.

    Full Text Available In this study, I focus on the problem of relations between art and theoretical work when they are performed in hypertext/hypermedia Net Art environment. Mark Amerika’s hypermedia practice, produced by digital technologies and focused on the questions of status, functions and modes of art and theory productions in information and biopolitical society, is considered as a case study. Amerika uses hypertext and hypermedia for realization of research art practice and as a media of post-pedagogical and theoretical work which deviate from determined types of scholarly discourses about art and expanding the concept of writing in hypermedia direction. Referring to biopolitical theories, Amerika emphasizes the communication linkage problem between biological organism and networked, hypertextual systems which is always de/regulatory. Remixology, implemented in digital, interactive internet environment, Amerika considers as a critical metaactivity against the manipulation of behavior in mass media of communications space and system of global networking.

  12. An Effective Combined Feature For Web Based Image Retrieval

    2015-08-01

    Full Text Available Abstract Technology advances as well as the emergence of large scale multimedia applications and the revolution of the World Wide Web has changed the world into a digital age. Anybody can use their mobile phone to take a photo at any time anywhere and upload that image to ever growing image databases. Development of effective techniques for visual and multimedia retrieval systems is one of the most challenging and important directions of the future research. This paper proposes an effective combined feature for web based image retrieval. Frequently used colour and texture features are explored in order to develop a combined feature for this purpose. Widely used three colour features Colour moments Colour coherence vector and Colour Correlogram and three texture features Grey Level Co-occurrence matrix Tamura features and Gabor filter were analyzed for their performance. Precision and Recall were used to evaluate the performance of each of these techniques. By comparing precision and recall values the methods that performed best were taken and combined to form a hybrid feature. The developed combined feature was evaluated by developing a web based CBIR system. A web crawler was used to first crawl through Web sites and images found in those sites are downloaded and the combined feature representation technique was used to extract image features. The test results indicated that this web system can be used to index web images with the combined feature representation schema and to find similar images. Random image retrievals using the web system shows that the combined feature can be used to retrieve images belonging to the general image domain. Accuracy of the retrieval can be noted high for natural images like outdoor scenes images of flowers etc. Also images which have a similar colour and texture distribution were retrieved as similar even though the images were belonging to deferent semantic categories. This can be ideal for an artist who wants

    The syndrome Relative Energy Deficiency in Sport (RED-S) is a clinical entity characterized by low energy availability (LEA), which can negatively affect the health and performance of both male and female athletes. The underlying mechanism of RED-S is an inadequacy of dietary energy to support optimal health and performance. This syndrome refers to impaired physiological function including metabolic rate, menstrual function, bone health, immunity, protein synthesis, and cardiovascular health, with psychological consequences which can either precede (through restrictive dietary habits) or result from RED-S. The term RED-S extends beyond the condition termed the "Female Athlete Triad". Formerly known as synchronized swimming, artistic swimming is an Olympic sport requiring a high level of fitness as well as technical skill and artistry. The risk of RED-S is high in artistic swimming as it is an aesthetic, judged sport with an emphasis on a lean physique. RED-S is of significant concern in the sport of artistic swimming because of the potential negative effects on physical and mental health as well as consequences on athletic performance. This paper reviews health and performance consequences associated with LEA resulting in RED-S in artistic swimming. Medical and nutritional considerations specific to artistic swimming are reviewed and methods to help detect and manage RED-S are discussed. Prevention and management of RED-S in this athlete population should be a priority for coaches and the sport medicine professionals working with artistic swimming athletes should utilize the RED-S CAT, a Clinical Assessment Tool for screening and managing RED-S.

  14. Performance Evaluation of Downscaling Sentinel-2 Imagery for Land Use and Land Cover Classification by Spectral-Spatial Features

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Land Use and Land Cover (LULC classification is vital for environmental and ecological applications. Sentinel-2 is a new generation land monitoring satellite with the advantages of novel spectral capabilities, wide coverage and fine spatial and temporal resolutions. The effects of different spatial resolution unification schemes and methods on LULC classification have been scarcely investigated for Sentinel-2. This paper bridged this gap by comparing the differences between upscaling and downscaling as well as different downscaling algorithms from the point of view of LULC classification accuracy. The studied downscaling algorithms include nearest neighbor resampling and five popular pansharpening methods, namely, Gram-Schmidt (GS, nearest neighbor diffusion (NNDiffusion, PANSHARP algorithm proposed by Y. Zhang, wavelet transformation fusion (WTF and high-pass filter fusion (HPF. Two spatial features, textural metrics derived from Grey-Level-Co-occurrence Matrix (GLCM and extended attribute profiles (EAPs, are investigated to make up for the shortcoming of pixel-based spectral classification. Random forest (RF is adopted as the classifier. The experiment was conducted in Xitiaoxi watershed, China. The results demonstrated that downscaling obviously outperforms upscaling in terms of classification accuracy. For downscaling, image sharpening has no obvious advantages than spatial interpolation. Different image sharpening algorithms have distinct effects. Two multiresolution analysis (MRA-based methods, i.e., WTF and HFP, achieve the best performance. GS achieved a similar accuracy with NNDiffusion and PANSHARP. Compared to image sharpening, the introduction of spatial features, both GLCM and EAPs can greatly improve the classification accuracy for Sentinel-2 imagery. Their effects on overall accuracy are similar but differ significantly to specific classes. In general, using the spectral bands downscaled by nearest neighbor interpolation can meet

    The aim of this paper is to analyze the aesthetic characteristics of the human females' gaze using anthropometry and to present an artistic model to represent it: "The Frame Concept." In this model, the eye fissure represents a painting, and the most peripheral shadows around it represent the frame of this painting. The narrower the frame, the more aesthetically pleasing and youthful the gaze appears. This study included a literature review of the features that make the gaze appear attractive. Photographs of models with attractive gazes were examined, and old photographs of patients were compared to recent photographs. The frame ratio was defined by anthropometric measurements of modern portraits of twenty consecutive Miss World winners. The concept was then validated for age and attractiveness across centuries by analysis of modern female photographs and works of art acknowledged for portraying beautiful young and older women in classical paintings. The frame height inversely correlated with attractiveness in modern female portrait photographs. The eye fissure frame ratio of modern idealized female portraits was similar to that of beautiful female portraits idealized by classical artists. In contrast, the eye fissure frames of classical artists' mothers' portraits were significantly wider than those of beautiful younger women. The Frame Concept is a valid artistic tool that provides an understanding of both the aesthetic and aging characteristics of the female periorbital region, enabling the practitioner to plan appropriate aesthetic interventions.

    Finding ways of increasing animal production with low external inputs and without compromising reproductive performances is a key issue of livestock systems sustainability. One way is to take advantage of the diversity and interactions among components within livestock systems. Among studies that investigate the influence of differences in animals' individual abilities in a herd, few focus on combinations of cow breeds with contrasting features in dairy cattle herds. This study aimed to analyse the performances and management of such multi-breed dairy cattle herds. These herds were composed of two types of dairy breeds: 'specialist' (Holstein) and 'generalist' (e.g. Montbeliarde, Simmental, etc.). Based on recorded milk data in southern French region, we performed (i) to compare the performances of dairy herds according to breed-type composition: multi-breed, single specialist breed or single generalist breed and (ii) to test the difference of milk performances of specialist and generalist breed cows (n = 10 682) per multi-breed dairy herd within a sample of 22 farms. The sampled farmers were also interviewed to characterise herd management through multivariate analysis. Multi-breed dairy herds had a better trade-off among milk yield, milk fat and protein contents, herd reproduction and concentrate-conversion efficiency than single-breed herds. Conversely, they did not offer advantages in terms of milk prices and udder health. Compared to specialist dairy herds, they produce less milk with the same concentrate-conversion efficiency but have better reproductive performances. Compared to generalist dairy herds, they produce more milk with better concentrate-conversion efficiency but have worse reproductive performances. Within herds, specialist and generalist breed cows significantly differed in milk performances, showing their complementarity. The former produced more milk for a longer lactation length while the latter produced milk with higher protein and fat

    Most people are taught at a young age that Art and Science are two opposing subjects. My culture (Dakota-Sioux), teaches that every human being contains both male and female. The goal is to embrace the two opposing tendencies and live in balance. I am both a scientist (MS WashU 2008) and an artist (MFA Yale 2000). In my ambition to embrace both talents I have found very fertile ground. I will present a collection of "Four Direction Star Paintings". My ideas revolve around the four cardinal directions: North, East, South and West in relation to the four seasons and the stars as "teachers" or at least old friends. These ideas reflect everyday living as well as more intense Lakota ceremonies. The Star Paintings are sparkling, celestial guideposts. Amazingly, some of these ideas are embedded in both Western Science and Native American culture. This connection is golden. Indigenous peoples throughout the world have always had connections with the celestial skies. It is my goal to tap into this ancient connection and use it to establish new methodology for teaching science. Currently, I am painting a sixteen foot medicine teepee while working on my graduate degree in physics. I am funded by a Graduate Research Grant from the National Science Foundation.

    Full Text Available Here, we and others describe an unusual neurorobotic project, a merging of art and science called MEART, the semi-living artist.We built a pneumatically actuated robotic arm to create drawings, as controlled by a living network of neurons from rat cortex grown on a multielectrode array (MEA. Such embodied cultured networks formed a real-time closed-loop system which could now behave and receive electrical stimulation as feedback on its behavior.We used MEART and simulated embodiments, or animats, to study the network mechanisms that produce adaptive, goal-directed behavior. This approach to neural interfacing will help instruct the design of other hybrid neuralrobotic systems we call hybrots. The interfacing technologies and algorithms developed have potential applications in responsive deep brain stimulation systems and for motor prosthetics using sensory components. In a broader context, MEART educates the public about neuroscience, neural interfaces, and robotics. It has paved the way for critical discussions on the future of bio-art and of biotechnology.

  20. Interaction of cerebral hemispheres and artistic thinking

    Nikolaenko, Nikolay N.

    1998-07-01

    Study of drawings by patients with local lesions of the right or left hemisphere allows to understand how artistic thinking is supported by brain structures. The role of the right hemisphere is significant at the early stage of creative process. The right hemisphere is a generator of nonverbal visuo-spatial thinking. It operates with blurred nonverbal images and arrange them in a visual space. With the help of iconic signs the right hemisphere reflects the world and creates perceptive visual standards which are stored in the long-term right hemisphere memory. The image, which appeared in the `inner' space, should be transferred into a principally different language, i.e. a left hemispheric sign language. This language operates with a number of discrete units, logical succession and learned grammar rules. This process can be explained by activation (information) transfer from the right hemisphere to the left one. Thus, natural and spontaneous creative process, which is finished by a conscious effort, can be understood as an activation impulse transfer from the right hemisphere to the left one and back.

    Heat stress in glass industry is mainly studied in large and highly mechanized manufacturing Units. To the contrary, few studies were carried out in small factories specialized in hand-made products. To stress the need of combined objective and medical surveys in these environments, this paper deals with a simultaneous climatic and physiological investigation of working conditions in artistic crystal glass factories in Tuscany (Italy). The microclimatic monitoring, through a continuous survey has been carried out in early spring. The main physiological parameters (metabolic rate, heart rate, tympanic temperature and water loss) were measured over the whole shifts. The results show that, despite the arduousness of the working conditions, the heat stress levels are physiologically tolerable. The predictions made using the PHS model at the Analysis level described in ISO 15265 agree closely to the observed values, validating the use of PHS model in these conditions. This model was then used to analyse what is likely to be the situation during the summer. It is concluded that the heat constraint will be very high and that some steps must be taken from the spring to monitor closely the exposed workers in the summer and take measures to prevent any heat accident.

    Background The most frequent behavioral manifestations in Parkinson's disease (PD) are attributed to the dopaminergic dysregulation syndrome (DDS), which is considered to be secondary to the iatrogenic effects of the drugs that replace dopamine. Over the past few years some cases of patients improving their creative abilities after starting treatment with dopaminergic pharmaceuticals have been reported. These effects have not been clearly associated to DDS, but a relationship has been pointed out. Methods Case study of a patient with PD. The evolution of her paintings along medication changes and disease advance has been analyzed. Results The patient showed a compulsive increase of pictorial production after the diagnosis of PD was made. She made her best paintings when treated with cabergolide, and while painting, she reported a feeling of well-being, with loss of awareness of the disease and reduction of physical limitations. Conclusions Dopaminergic antagonists (DA) trigger a dopaminergic dysfunction that alters artistic creativity in patients having a predisposition for it. The development of these skills might be due to the dopaminergic overstimulation due to the therapy with DA, which causes a neurophysiological alteration that globally determines DDS. PMID:23185168

    A high performance organic integrated device (OID) with ultraviolet photodetective and electroluminescent (EL) properties was fabricated by using a charge-transfer-featured naphthalimide derivative of 6-(3,5-bis-[9-(4-t-butylphenyl)-9H-carbazol-3-yl]-phenoxy)-2- (4-t-butylphenyl)-benzo[de]isoquinoline-1,3-dione (CzPhONI) as the active layer. The results showed that the OID had a high detectivity of 1.5 × 10{sup 11} Jones at −3 V under the UV-350 nm illumination with an intensity of 0.6 mW/cm{sup 2}, and yielded an exciplex EL light emission with a maximum brightness of 1437 cd/m{sup 2}. Based on the energy band diagram, both the charge transfer feature of CzPhONI and matched energy level alignment were responsible for the dual ultraviolet photodetective and EL functions of OID.

    Full Text Available Eyes are the windows to the soul. In all ages we are convinced that the most authentic and beautiful sights are in our eyes. This, however, is just like an indiscernible legal provision that confines the development of art all the time. Artistic vision may conflict with visual impression, so vision science for artistic creation is of the myriads of changes. Vision is in fact a reflection of a physical phenomenon, and “light” is the base for us to see the diverse world. Exploring vision theories and intentionally using them in artistic creation can be a good attempt. Vision advantages and characteristics will be effectively reflected when applying the vision theories to graphic design as well as to indoor and outdoor designs. This article will make an exploration of the vision science from several perspectives of artistic creation, with focusing on the relation between art and science.

    In the late 19(th) century, authors writing on aesthetics often referred to architecture to justify establishing a new hierarchy between things beautiful and things useful, a change underwritten by the rising sociological and anthropological perspectives on art. Meanwhile, architects debated the origins and evolution of artistic styles from the earliest forms of art to the most advanced monumental art works, a debate that fundamentally transformed the relationship between artistic expression and material determinism.

    Highlights: • Source term analyses in a PWR of mitigated thermally-induced SGTR scenario performed. • Experimental ARTIST program results on aerosol scrubbing efficiency used in analyses. • Results demonstrate enhanced aerosol retention in a flooded steam generator. • High aerosol retention cannot be predicted by current theoretical scrubbing models. - Abstract: Integral source-term analyses are performed using MELCOR for a PWR Station Blackout (SBO) sequence leading to induced steam generator tube rupture (SGTR). In the absence of any mitigation measures, such a sequence can result in a containment bypass where the radioactive materials can be released directly to the environment. In some SGTR scenarios flooding of the faulted SG secondary side with water can mitigate the accident escalation and also the release of aerosol-borne and volatile radioactive materials. Data on the efficiency of aerosol scrubbing in an SG tube bundle were obtained in the international ARTIST project. In this paper ARTIST data are used directly with parametric MELCOR analyses of a mitigated SGTR sequence to provide more realistic estimates of the releases to environment in such a type of scenario or similar. Comparison is made with predictions using the default scrubbing model in MELCOR, as a representative of the aerosol scrubbing models in current integral codes. Specifically, simulations are performed for an unmitigated sequence and 2 cases where the SG secondary was refilled at different times after the tube rupture. The results, reflecting the experimental observations from ARTIST, demonstrate enhanced aerosol retention in the highly turbulent two-phase flow conditions caused by the complex geometry of the SG secondary side. This effect is not captured by any of the models currently available. The underlying physics remains only partly understood, indicating need for further studies to support a more mechanistic treatment of the retention process.

  14. The Unmarriageable Artist: the History Paintings of Edgar Degas

    Full Text Available In this paper, Edgar Degas’ history paintings are read as the painter’s reflection on the irreconcilability of married life and artistic vocation, a major theme of discussion among artists and writers in nineteenth-century France. In The Young Spartans Exercising (1861 we see bachelors being banned from participation in the Gymnopaediae. In The Daughter of Jephthah (1859-60, Semiramis Building Babylon (1861 and Scene of War in the Middle Ages (1865, Degas shows famous unmarried women, femmes fortes who have chosen to pursue spiritual rather than mortal passions, all alter-egos for the artiste célibataire who chooses devotion to art over a family-centred bourgeois life. This article contributes to the view that Degas was neither a misogynist nor a narrow-minded bourgeois. Far from having preconceived patriarchal ideas on marriage and women, Degas choose to remain an artiste célibataire in accordance with the more extreme aspects of the nineteenth-century French cult of the artist as genius. It is the idea of the exceptional status of the artist that Degas elaborates in his history paintings, and that rendered him unmarriageable.

  17. Psychostimulants and Artistic, Musical, and Literary Creativity.

    Science.gov (United States)

    Smith, Iain

    2015-01-01

    This chapter explores links between psychostimulants and creativity in the arts. These links are set in the context of an overview of the association between mind-altering drugs in general and specific branches of the arts, particularly literature. The economic impact of the psychostimulants both historically and in today's world has been substantial and this is mirrored in the culture of the countries involved with the trade in these special commodities. As with other families of addictive drugs, the psychostimulants are sought out more frequently than is the norm by creative individuals who then may represent the drugs in their art or associate the drugs with their creativity. The creative process is outlined and it is noted that if a drug helps at all with creativity then the specific properties of the drug may link it to a particular stage of the creative process. Stimulants are particularly associated with the evaluation and elaboration stage of the creative process and in particular nicotine and caffeine have been used in this way by writers when putting words on paper. The ability of psychostimulants to boost convergent thinking is the main mechanism at work but this is at a cost as divergent thinking is diminished. The other findings of note in this review are that particular venues based around the consumption of a psychostimulants can act as a creative hub-café culture in Paris and Vienna and early modern Europe-and that particular drugs can come to define an artistic grouping as with the Beats and the group around Warhol who had a preference for amphetamine. © 2015 Elsevier Inc.

  18. Dust in the Quasar Wind (Artist Concept)

    Science.gov (United States)

    2007-01-01

    Dusty grains -- including tiny specks of the minerals found in the gemstones peridot, sapphires and rubies -- can be seen blowing in the winds of a quasar, or active black hole, in this artist's concept. The quasar is at the center of a distant galaxy. Astronomers using NASA's Spitzer Space Telescope found evidence that such quasar winds might have forged these dusty particles in the very early universe. The findings are another clue in an ongoing cosmic mystery: where did all the dust in our young universe come from? Dust is crucial for efficient star formation as it allows the giant clouds where stars are born to cool quickly and collapse into new stars. Once a star has formed, dust is also needed to make planets and living creatures. Dust has been seen as far back as when the universe was less than a tenth of its current age, but how did it get there? Most dust in our current epoch forms in the winds of evolved stars that did not exist when the universe was young. Theorists had predicted that winds from quasars growing in the centers of distant galaxies might be a source of this dust. While the environment close to a quasar is too hot for large molecules like dust grains to survive, dust has been found in the cooler, outer regions. Astronomers now have evidence that dust is created in these outer winds. Using Spitzer's infrared spectrograph instrument, scientists found a wealth of dust grains in a quasar called PG2112+059 located at the center of a galaxy 8 billion light-years away. The grains - including corundum (sapphires and rubies); forsterite (peridot); and periclase (naturally occurring in marble) - are not typically found in galaxies without quasars, suggesting they might have been freshly formed in the quasar's winds.

    2008-05-01

    Full Text Available Through its incorporation of socio-scientific, participative and artistic elements, the "Citizens' Exhibition" is an example of how applied performative social science can be implemented. The method was created by teaching qualitative methods and community psychology approaches in courses for students of psychology in the 1990's. The Citizens' Exhibition combines qualitative methods, such as interview and text interpretation, with artistic-aesthetic methods, such as photography and film, to form an integrated concept. In the tradition of action research, the practice is applied in the exploration of societal issues. The Citizens' Exhibition supports dialogue and furthering communication processes between the stakeholders through the presentation of diverse perspectives. In this regard, the staging of the exhibition opening has a particular importance. The following article about the Citizens' Exhibition presents the practice's origin and history in the first section and, in the second section, offers an introduction to the individual methodological steps. In the third section, various Citizens' Exhibitions are described as illustrations of the method. The last section discusses the vision of the Citizens' Exhibition, its performative component, strengths and limitations, considers the results of an existing evaluation study and looks at the future uses of the practice. Particular regard should be paid here to a combination of methods that enable a long-term participation effect, the expansion of participatory possibilities for the research subjects, and experimentation with additional artistic methods.

Black-Right-Pointing-Pointer The new prototype of an even more powerful 2nd generation SIO II device. Black-Right-Pointing-Pointer The fusion of all blocks of board logic (serializer, FIFO, TDC, merge engine, PCIe controller) into one single FPGA simplifying the boards physical layout significantly. - Abstract: The SIO DAQ concept used at the ASDEX Upgrade fusion experiment features data acquisition from a modular front-end (a modular crate-and-interface-cards concept for analog and digital input and output) over standardized serial lines and via a serial input/output computer interface card (the SIO card) in real-time directly into the main memory of a host computer. Deployment of a series of diagnostics using SIO led to various solutions and configurations for the different requirements. Experience has been gained and lessons learned applying the SIO concept at its technical limits. Requirements for a further development of the SIO concept have been identified, and a performance improvement by a factor of 4-8 beyond its current limits seems achievable. An effort has been started to develop a SIO version 2 (SIO II) featuring upgraded serial links and a more powerful FPGA for merging and forwarding data streams to host computer memory. (Compatibility with the existing SIO (SIO I) front-end system has to be maintained.) This paper presents results achieved and experiences gained in the deployment of SIO I, the status of SIO II development (currently in the prototype phase), and projected enhancements and updates to existing implementations.

    Full Text Available Abstract The table vault is an event of male and female Artistics Gymnastics. Although it can be performed in a variety of rotations and body positions in different phases, it can be separated in three groups: handspring, Yurchenko and Tsukahara. It is believed that kinematic variables of vault may vary according to group of vault or gymnast body position, but few studies compares the real differences among the three groups of vaults, comparing and describing the variables in different phases. Vault kinematic variables could be diversifying according to the approach or position of the vaulting, but little has been studied about the biomechanical differences, comparing and describing behaviours at different stages. The aim of this study was to organize critical, objective and to systematize the most relevant kinematic variables to performance on vaulting. A Meta analysis over the basis Pubmed, Sport Discus and Web of Science were performed about this issue. From the selected references, we described and analyzed the kinematics of the table vault. Vault can be characterized in seven phases of analysis. Most of the studies are descriptive, and some do not descript all phases. Differences among vault variables according to group vaults, technical level and gender were analysed only in recent studies. There still gaps of knowledge about kinematic variables of table vault, in order to provide comprehensive information about all possibilities of vaults in this gymnastic event. It is concluded that kinematic variables of table vault depends upon vault group and may be considered to the improvement of technical performance. More researches are needed to approach the coaching interface with biomechanics applicable knowledge.

  5. ARTIST process. A novel chemical process for treatment of spent nuclear fuel

    International Nuclear Information System (INIS)

    Tachimori, Shoichi

    2001-10-01

    A new chemical process, ARTIST process, is proposed for the treatment of spent nuclear fuel. The main concept of the ARTIST process is to recover and stock all actinides (Ans) as two groups, uranium (U) and a mixture of transuranics (TRU), to preserve their resource value and to dispose solely fission products (FPs). The process is composed of two main steps, an U exclusive isolation and a total recovery of TRU; which copes with the nuclear non-proliferation measures, and additionally of Pu separation process and soft N-donor process if requested, and optionally of processes for separation of long-lived FPs. These An products: U-product and TRU-product, are to be solidified by calcination and allowed to the interim stockpile for future utilization. These separations are achieved by use of amidic extractants in accord with the CHON principle. The technical feasibility of the ARTIST process was explained by the performance of both the branched alkyl monoamides in extracting U and suppressing the extraction of tetravalent Ans due to the steric effect and the diglycolic amide (TODGA) in thorough extraction of all TRU by tridentate fashion. When these TRU are requested to put into reactors, LWR or FBR, for power generation or the Accelerator - Driven System (ADS) for transmutation, Pu (Np) or Am-Cm (Np) are to be extracted from the TRU-product.

  6. Using artwork to understand the experience of mental illness: Mainstream artists and Outsider artists

    Rustin, Terry A.

    2008-01-01

    Objective: Artwork and psychiatric disorders are often linked. Accomplished artists with psychiatric disorders express themselves and their emotional distress through their works, and art therapists use the visual arts to help clients understand their problems and cope with them. There have been a number of psychiatric patients with no previous art training who produced artwork that many consider museum-worthy (Art Brut, or Outsider Art.) For the past two years, I have used artwork in another way: to better understand my clients and their psychiatric disorders. Methods: Presented here are paintings I have made about the mental illness experience of some of my clients, all well known to me through their therapy. It is a form of visual psychodrama, in which I reverse roles with the client through the paintings. My goal has been to experience the stresses felt by my clients so that I can understand them better. Results: The paintings have served as a point of embarkation for therapy sessions, as a means of clarifying a client’s experience, and as a way to show clients that their therapist is attending to what they say. Countertransference undoubtedly plays a role in my choice of clients and their portrayals, but the intent is to help me better understand the clients’ experiences. Included here are images of some of these paintings with a short psychiatric history of the client about whom they were made. Accompanying each one are responses from the clients upon viewing “their” paintings, and a discussion of the client’s psychiatric disorder. Conclusions: Making these paintings has helped me understand better the feelings of isolation, rejection, loss, and alienation that many of my clients experience every day. In turn, they tell me that viewing the paintings is an intense experience for them as well. As an outsider artist, I must leave it to the viewer to determine whether or not these paintings qualify as “art.” PMID:19742284

  7. A New Proposal on Analysis of Artistic Creativity through Introspection

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The genesis of the creative process in Art is currently conceived as the intellectual selection by the artist of fragments of memory from her/his personal, cultural and emotional experience. Interpretation of the artistic object has been systematically developed from an external perspective of art history, literature, and fine arts or of medicine and psychology. Recent neurological findings on the molecular nature of memory have revolutioned the knowledge of the mental process of memorization, remembrance and creative synthesis. A movement of scientists defends the necessity of new tools to access mental processes, inherently subjective, such as artistic creativity. In the light of those evidences, we propose a new approach to the artwork starting from a first-person analysis, namely introspection, which offers an interpretation of the genesis of the artwork from his/her own memory. The scientific, philosophical and social background on the neuropsychological processes guiding the creative activity is reviewed. Our purpose is to integrate the previous approaches from a wide multidisciplinary perspective, and to pose a new reflection on how the autobiographical and intertextual data from the artist are modeled in a dynamic way in the complex net of mental interactions up to reach the creation of an artwork, which highlights an original new vision on the reading of art. This insight from first-person analysis might complement and enrich other analyses external to the artist.

    Visual art because of its artistic context can be related to the general idea of providing alternative perceptual experiences. However, research examining the neural basis of art beyond the paradigm of beauty has been neglected. This study seeks to determine how the perception of a body in an artwork can be distinguished from the perception of a body in a non-artistic photography. While viewing different body representations in both artworks and photographs, subjects were required to evaluate the appeal of the portrayed persons. By using functional magnetic resonance imaging (fMRI) we show that the perception of a body within the context of art leads to a higher activation in the right parietal cortex and the extrastriate cortex bilaterally. Relating this result to concepts from previous research, we suggest that the perception of art is linked to visuo-spatial coding and also motor mapping. In contrast, the higher activity in the ventromedial prefrontal cortex and the primary visual cortex during the perception of a body in a non-artistic frame of reference, i.e. in a photograph, can be linked to processes of person evaluation. Possibly, the task to judge the appeal of a person in a photograph might be more daunting and, thus, cause emotional and even moral challenges being reflected in the ventromedial prefrontal activity. Taken together, perceptual experiences within an artistic vs. a non-artistic frame of reference are based on distinct patterns of neuronal activity. Copyright © 2012 Elsevier Inc.

    2005-11-01

    Full Text Available The paper presents an investigation into a time-frequency (TF method for extracting features from the electroencephalogram (EEG recorded from subjects performing imagination of left- and right-hand movements. The feature extraction procedure (FEP extracts frequency domain information to form features whilst time-frequency resolution is attained by localising the fast Fourier transformations (FFTs of the signals to specific windows localised in time. All features are extracted at the rate of the signal sampling interval from a main feature extraction (FE window through which all data passes. Subject-specific frequency bands are selected for optimal feature extraction and intraclass variations are reduced by smoothing the spectra for each signal by an interpolation (IP process. The TF features are classified using linear discriminant analysis (LDA. The FE window has potential advantages for the FEP to be applied in an online brain-computer interface (BCI. The approach achieves good performance when quantified by classification accuracy (CA rate, information transfer (IT rate, and mutual information (MI. The information that these performance measures provide about a BCI system is analysed and the importance of this is demonstrated through the results.

    Full Text Available This work searched to examine the manifestations of creativity in the artist-childhood relationship. Our reflection took for theorical basis authors/researchers like André Malraux, Howard Gardner and Charles Baudelaire in parallel with three novels of occidental literature: Gogol’s O retrato, Machado de Assis’ Um homem célebre and Cantiga de esponsais. Why the “genius is such the childhood refounded”, like said the poet of Flores do mal? This is the interrogation that started the exam of this relationship. This way, the research questioned the absolut supremacy of the racional doing in the artistic creation trying to show a variable degree of influence of the imagination, unconsciousness or of an intruder element indenpendently of the knowledge. There would be like this in childhood and in certain artists an incompletude that “shine a lapse” and would allow an “invention of the possible”.

    2014-01-01

    The present study challenges the notion that judgments of artistic quality are based on stable aesthetic standards. We propose that such standards are a delusion and that judgments of artistic quality are the combined result of exposure, elaboration, and discourse. We ran two experiments using elaboration tasks based on the repeated evaluation technique in which different versions of the Mona Lisa had to be elaborated deeply. During the initial task either the version known from the Louvre or an alternative version owned by the Prado was elaborated; during the second task both versions were elaborated in a comparative fashion. After both tasks multiple blends of the two versions had to be evaluated concerning several aesthetic key variables. Judgments of artistic quality of the blends were significantly different depending on the initially elaborated version of the Mona Lisa, indicating experience-based aesthetic processing, which contradicts the notion of stable aesthetic standards.

    Full Text Available In Estonian art history, the beginning of the 20th century is the era of the birth of nationalist art. This is the time when the first artists to study abroad, the brothers Paul and Kristjan Raud, and Ants Laikmaa return home from their studies in Düsseldorf and Munich. In the homeland, these artists’ cultural and political spirit brought them into contact with the Young Estonians, one generation younger than they were, whose overall world-view and artistic views they came to shape. The program of the Young Estonians included the furthering of cultural life as a whole; therefore they participated enthusiastically in discussions about the visual arts, and ways in which to advance art in the homeland. Through the mediation of Ants Laikmaa, they made contact with Nikolai Triik, an artist of their own generation, who in turn engaged his former fellow students from the Stieglitz School of Applied Arts in St. Petersburg – Aleksander Tassa, Jaan Koort, and Konrad Mägi. The interests and travel destinations of writers and artists were similar: they found themselves drawn primarily to Scandinavia, then Paris. Young Estonia’s almanacs and magazines were illustrated and adorned by reproductions of these same artists’ works, and artists contributed their writings on art to the publication. Nikolai Triik was artistic editor for the Young Estonia magazine, thanks to his stronger ties with the homeland and his greater authority. In the years 1909 and 1914 Young Estonia organized art exhibits, in which several artists studying abroad found their first reception among a homeland public. Young Estonia created a new standard in Estonian book design. Discussions began around the question of ”nationalism” in art. The Young Estonia period 1905–1915 was an era of great change in Estonian art, and the artists connected with the movement played a major role in subsequent developments. Together they established the art association ”Pallas” in 1918

    Full Text Available The aim is to carry out a generalized analysis of the history of formation of a new artistic language in contemporary arts and crafts of Dagestan. An innovative search for applied artist has gained further development in a series of works of the leading masters of folk arts and crafts of Dagestan. Discussion. For millennia, arts and crafts of Dagestan have been organically linked with the life of people and their everyday way of life and daily activities, with their worldview and understanding of beauty. In the middle of the 1st millennium BC in the mountainous Dagestan, art of bronze casting has reached a high degree of perfection, most vividly represented by statues of different wild and domestic animals. Images of animals are interpreted generically, without study of small details, but with the characteristic features of the exterior. Paired images of birds are often found in the arts and crafts of the medieval Dagestan. This heraldic composition, two-part or in conjunction with the sacred tree - a three-part, presented in metal-plastic and carved stone and wood, was one of the most popular and enduring decorative items that was common during the Middle Ages and has survived to the present day. This also has been further developed and improved and inherited by craftsmen of Dagestan.Conclusion. When creating works of arts and crafts craftsmen use diverse traditional arts and engineering techniques, the ancient but substantially revised and reinterpreted iconic scenes and ornamental motifs. In art, folk craftsmen emphasize the unity of man and nature. Most ornamental motifs common in Dagestan, go back to the very specific nature prototypes. Compositional structure, as the artistic analysis shows, is often borrowed from nature. This feeling becomes a condition for cultural and biological development, acting as a factor of co-evolution of man and nature.

  17. A High-Performance FPGA-Based Image Feature Detector and Matcher Based on the FAST and BRIEF Algorithms

    2015-10-01

    Full Text Available Image feature detection and matching is a fundamental operation in image processing. As the detected and matched features are used as input data for high-level computer vision algorithms, the matching accuracy directly influences the quality of the results of the whole computer vision system. Moreover, as the algorithms are frequently used as a part of a real-time processing pipeline, the speed at which the input image data are handled is also a concern. The paper proposes an embedded system architecture for feature detection and matching. The architecture implements the FAST feature detector and the BRIEF feature descriptor and is capable of establishing key point correspondences in the input image data stream coming from either an external sensor or memory at a speed of hundreds of frames per second, so that it can cope with most demanding applications. Moreover, the proposed design is highly flexible and configurable, and facilitates the trade-off between the processing speed and programmable logic resource utilization. All the designed hardware blocks are designed to use standard, widely adopted hardware interfaces based on the AMBA AXI4 interface protocol and are connected using an underlying direct memory access (DMA architecture, enabling bottleneck-free inter-component data transfers.

    Generalized Joint Hypermobility (GJH) is suggested as a contributing factor for injuries in young athletes and adults. It is presumed that GJH causes decreased joint stability, thereby increasing the risk of joint and soft tissue injuries during sports activities. The aim of this study was to determine the correlation between the hypermobility rate (using the Beighton`s modification of the Carter-Wilkinson criteria of hypermobility) in gymnasts and injury rate, during the period of one year. This study observed 24 artistic gymnasts (11-26 years old), members of Qatar National Team in artistic gymnastics. We examined the Beighton joint hypermobility screen and a seasonal injury survey. The gymnasts characteristics (age, gender) and gymnastics characteristics (training per day and number of years in training artistic gymnastics) and its' relations to injury rate were also included. The most common injury was the lower back pain injury, followed by knee, shoulder, hip and ankle injuries. We found strong correlation of number of years gymnastics training and injury rate (p0.05). According to this study there is no correlation between GJH rate and injury rate in artistic gymnasts in Qatar. Total training period in gymnastics have greater contribution in injury rate.

    Bipolar disorder is one of the most common mood disorders characterized by large and invalidating mood swings. Several projects focus on the development of decision support systems that monitor and advise patients, as well as clinicians. Voice monitoring and speech signal analysis can be exploited to reach this goal. In this study, an Android application was designed for analyzing running speech using a smartphone device. The application can record audio samples and estimate speech fundamental frequency, F0, and its changes. F0-related features are estimated locally on the smartphone, with some advantages with respect to remote processing approaches in terms of privacy protection and reduced upload costs. The raw features can be sent to a central server and further processed. The quality of the audio recordings, algorithm reliability and performance of the overall system were evaluated in terms of voiced segment detection and features estimation. The results demonstrate that mean F0 from each voiced segment can be reliably estimated, thus describing prosodic features across the speech sample. Instead, features related to F0 variability within each voiced segment performed poorly. A case study performed on a bipolar patient is presented.

  1. Climate Change and Glacier Retreat: Scientific Fact and Artistic Opportunity

    Fagre, D. B.

    2008-12-01

    Mountain glaciers continue to retreat rapidly over most of the globe. In North America, at Glacier National Park, Montana, recent research results from Sperry Glacier (2005-2007) indicate negative mass balances are now 3-4 times greater than in the 1950s. A geospatial model of glacier retreat in the Blackfoot-Jackson basin suggested all glaciers would be gone by 2030 but has proved too conservative. Accelerated glacier shrinkage since the model was developed has mirrored an increase in actual annual temperature that is almost twice the rate used in the model. The glaciers in Glacier National Park are likely to be gone well before 2030. A variety of media, curricula, and educational strategies have been employed to communicate the disappearance of the glaciers as a consequence of global warming. These have included everything from print media and television coverage to podcasts and wayside exhibits along roads in the park. However, a new thrust is to partner with artists to communicate climate change issues to new audiences and through different channels. A scientist-artist retreat was convened to explore the tension between keeping artistic products grounded in factually-based reality while providing for freedom to express artistic creativity. Individual artists and scientists have worked to create aesthetic and emotional images, using painting, poetry, music and photography, to convey core messages from research on mountain ecosystems. Finally, a traveling art exhibit was developed to highlight the photography that systematically documents glacier change through time. The aim was to select photographs that provide the most compelling visual experience for an art-oriented viewer and also accurately reflect the research on glacier retreat. The exhibit opens on January 11, 2009

    Creative drive and enhanced artistic-like production may emerge in patients with Parkinson's disease (PD) during dopaminergic therapy. However, it has not been described to date whether this artistic-like production results from dopaminergic drugs triggering innate skills or it could be considered as a repeated behavior possibly associated with impulse control disorders (ICDs). We investigated creative drive in a cohort of cognitively preserved patients with PD by means of the Torrance Test of Creative Thinking (TTCT). We also investigated a putative association between creative drive and ICDs in 36 PD patients with (PD-c) or without (PD-nc) increased artistic-like production and 36 healthy controls (HC). We considered artistic-like productivity to be enhanced if patients reported working on any form of art more than 2h per day after the introduction of dopaminergic treatment. The TTCT, the Barratt Impulsiveness Scale (BIS-11A), the Minnesota Impulsive Disorders Interview (MIDI), and the Punding Rating Scale were applied. Mean TTCT score of PD-c was found to be similar to HC (169.4±51.6 vs. 170.2±69.7, respectively), and both PD-c and HC had significantly higher TTCT scores than patients with PD-nc (125.4±46.1 Partistic-like production in patients with PD is not associated with impulsivity or ICDs. Artistic-like production might represent the emerging of innate skills in a subset of predisposed patients with PD on dopaminergic therapy. © 2011 The Author(s).

  3. Alexander von Humboldt and British artists: the Oriental taste

    Directory of Open Access Journals (Sweden)

    Garrido, Elisa

    2013-12-01

    Full Text Available Humboldtian landscape is the best result of a close relationship between artists and scientists in the context of the Enlightenment. Many artists inspired Humboldt to develop his concept of landscape as the best way of representing Nature, but some British artists in particular were a strong reference for him. Thomas Daniell and William Hodges had travelled to Asia creating a particular imagery, which inspired the desire to travel and the feeling of the exotic taste in Humboldt. Around Humboldt, mainly two types of artists have been studied: on the one hand, painter travellers who received direct instructions from Humboldt after his experience in America, and on the other, artists who started their trips by themselves after reading his works. However, this paper is focused on the links between Humboldt and these British painters of the Orient, whom he met on a European tour with Georg Forster, before making his trip to America.El paisaje teorizado por Humboldt es el resultado de una estrecha relación entre artistas y científicos, en el contexto de la Ilustración. Muchos artistas inspiraron a Humboldt a desarrollar su concepto del paisaje como la mejor forma de representar la naturaleza pero particularmente, algunos artistas británicos supusieron una fuerte referencia para él. Principalmente, alrededor de Humboldt se han estudiado dos tipos de artistas: por una parte, los pintores viajeros que recibieron instrucciones directas de Humboldt tras su experiencia en América y por otra, los artistas que iniciaron sus viajes por iniciativa propia tras haber leído los sus trabajos. Sin embargo, este texto se centra en las relaciones entre Humboldt y los pintores británicos de Oriente, a quienes él conoció en su viaje europeo junto a Georg Forster, antes de realizar su viaje americano.

  4. Early Sámi visual artists - Western fine art meets Sámi culture

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Johan Turi (1854–1936, Nils Nilsson Skum (1872–1951 and John Savio (1902–1938 were among the first Sámi visual artists. The production of their art work occurred between the 1910s and the early 1950s. Sámi aesthetics had its basis in folklore, i.e., handicraft or duodji, which did not follow the principle of art for art’s sake but combined beauty and practicality. Art was part of community life. Not until the 1970s was the word daidda, which is Finnish in origin and which means “art”, adopted into the Sámi language. Turi and Skum became famous through their books. They drew and wrote in order to pass the traditional knowledge of their people on to succeeding generations. They also wanted to introduce Sámi life and culture to non-Sámi people. One typical feature of their work is that they depicted Sáminess in a realistic way and sought to strengthen and preserve the Sámi identity through their art. In Turi and Skum’s work, both the documentation of community life and their own personal expression were strongly present and equally important; for this reason their pictures and texts have both practical and aesthetic dimensions. They did not attend school and were self-taught artists. The third pioneer of Sámi visual arts was John Savio, who, unlike the other two, attended secondary school and studied visual arts both independently and under the guidance of a mentor. He expressively combined Western ways of depiction with Sámi subjects. My article examines what made these early Sámi artists change over from Sámi handicraft, duodji, to Western visual arts, how they used Western pictorial conventions in dealing with their Sámi subjects, and the significance of their art for Sámi identity and culture. They lived and worked under cross pressure: the first few decades of the 20th century were characterized by racial theories that denigrated Sámi people, and the period following World War II was marked by demands for

    2017-11-01

    The article briefly describes the history of the Russian design education in the XIXth century within the context of the single pan-European artistic process development. The attention is drawn to the peculiar features and causes of insufficient efficiency. The article specifies the role of architecture as a style-forming type of the artistic and technical activity in the establishment of the art industry. It emphasizes the importance of the designation of a designer profession as a special type of design activities going beyond the limits of “the art for art’s sake”. It asserts its right to independence, emphasizes its applied relevance and cross-disciplinary nature. It reveals the determining role of such historical and cultural phenomenon as the Russian style in the establishment and self-determination of the national art industry. The article links the growth rates of the Russian art industry with the industrial production development level and the level of social and legal relations in the state.

  8. Visual mismatch negativity indicates automatic, task-independent detection of artistic image composition in abstract artworks.

    Menzel, Claudia; Kovács, Gyula; Amado, Catarina; Hayn-Leichsenring, Gregor U; Redies, Christoph

    2018-05-06

    In complex abstract art, image composition (i.e., the artist's deliberate arrangement of pictorial elements) is an important aesthetic feature. We investigated whether the human brain detects image composition in abstract artworks automatically (i.e., independently of the experimental task). To this aim, we studied whether a group of 20 original artworks elicited a visual mismatch negativity when contrasted with a group of 20 images that were composed of the same pictorial elements as the originals, but in shuffled arrangements, which destroy artistic composition. We used a passive oddball paradigm with parallel electroencephalogram recordings to investigate the detection of image type-specific properties. We observed significant deviant-standard differences for the shuffled and original images, respectively. Furthermore, for both types of images, differences in amplitudes correlated with the behavioral ratings of the images. In conclusion, we show that the human brain can detect composition-related image properties in visual artworks in an automatic fashion. Copyright © 2018 Elsevier B.V. All rights reserved.

    Many forms of art accurately depict physical attributes of their subjects. But how precisely do portraits capture personal, emotional, and behavioral aspects of individuals holding leadership positions in academic departments of anesthesiology? We examined formal portraits of the first three academic chairmen of anesthesiology in our department - Leroy D. Vandam, Benjamin G. Covino, and Simon Gelman and obtained information about the artists (George Augusta and Marc Klionsky) regarding how they conducted research on their subjects, and the methods they used to depict significant character traits into their art. We then correlated the artistic depiction with known biographical and behavioral qualities of these leaders. We found that the artists were remarkably astute in their observations and that they successfully captured both physical and emotional aspects of these chairmen in their portraits. Moreover, in one instance, significant early life experiences were added to the composition with subtlety. Individuals familiar with these chairmen and aware of their management style can easily appreciate the techniques employed by the artists. We conclude that art successfully depicted personal and executive attributes of these three academic anesthesia chairmen. Copyright © 2016 Elsevier B.V. All rights reserved.

  11. Computer-Based Image Analysis for Plus Disease Diagnosis in Retinopathy of Prematurity: Performance of the "i-ROP" System and Image Features Associated With Expert Diagnosis.

    2015-11-01

    We developed and evaluated the performance of a novel computer-based image analysis system for grading plus disease in retinopathy of prematurity (ROP), and identified the image features, shapes, and sizes that best correlate with expert diagnosis. A dataset of 77 wide-angle retinal images from infants screened for ROP was collected. A reference standard diagnosis was determined for each image by combining image grading from 3 experts with the clinical diagnosis from ophthalmoscopic examination. Manually segmented images were cropped into a range of shapes and sizes, and a computer algorithm was developed to extract tortuosity and dilation features from arteries and veins. Each feature was fed into our system to identify the set of characteristics that yielded the highest-performing system compared to the reference standard, which we refer to as the "i-ROP" system. Among the tested crop shapes, sizes, and measured features, point-based measurements of arterial and venous tortuosity (combined), and a large circular cropped image (with radius 6 times the disc diameter), provided the highest diagnostic accuracy. The i-ROP system achieved 95% accuracy for classifying preplus and plus disease compared to the reference standard. This was comparable to the performance of the 3 individual experts (96%, 94%, 92%), and significantly higher than the mean performance of 31 nonexperts (81%). This comprehensive analysis of computer-based plus disease suggests that it may be feasible to develop a fully-automated system based on wide-angle retinal images that performs comparably to expert graders at three-level plus disease discrimination. Computer-based image analysis, using objective and quantitative retinal vascular features, has potential to complement clinical ROP diagnosis by ophthalmologists.

    2010-01-01

    A central question in the field of attention is whether visual processing is a strictly limited resource, which must be allocated by selective attention. If this were the case, attentional enhancement of one stimulus should invariably lead to suppression of unattended distracter stimuli. Here we examine voluntary cued shifts of feature-selective attention to either one of two superimposed red or blue random dot kinematograms (RDKs) to test whether such a reciprocal relationship between enhanc...

  15. Online feature selection with streaming features.

    Science.gov (United States)

    Wu, Xindong; Yu, Kui; Ding, Wei; Wang, Hao; Zhu, Xingquan

    2013-05-01

    We propose a new online feature selection framework for applications with streaming features where the knowledge of the full feature space is unknown in advance. We define streaming features as features that flow in one by one over time whereas the number of training examples remains fixed. This is in contrast with traditional online learning methods that only deal with sequentially added observations, with little attention being paid to streaming features. The critical challenges for Online Streaming Feature Selection (OSFS) include 1) the continuous growth of feature volumes over time, 2) a large feature space, possibly of unknown or infinite size, and 3) the unavailability of the entire feature set before learning starts. In the paper, we present a novel Online Streaming Feature Selection method to select strongly relevant and nonredundant features on the fly. An efficient Fast-OSFS algorithm is proposed to improve feature selection performance. The proposed algorithms are evaluated extensively on high-dimensional datasets and also with a real-world case study on impact crater detection. Experimental results demonstrate that the algorithms achieve better compactness and higher prediction accuracy than existing streaming feature selection algorithms.

    The scientific investigation on metal artwork is meant to expand the knowledge regarding the technical skills developed by artists in sculpture manufacturing. Moreover, all the gathered data support the speculation about the motivations behind the choices of certain material or a specific casting and/or finishing method (e.g., aesthetic, economic or technical reasons, or both) and give fundamental information for planning adequate restoration interventions. The subject of this study is the Virtues sculptural group made at the end of the XVI century by Giambologna to decorate the Grimaldi Chapel in the church of San Francesco di Castelletto (Genoa, Italy). Six life-size statues depicting Charity, Justice, Hope, Fortitude, Faith, and Temperance (i.e., the artwork discussed in this article); seven bas-reliefs; and six winged representations of putti are what remains of the original monumental project. Different micro-invasive analytical techniques (scanning electron microscopy and energy dispersive x-ray spectroscopy, SEM-EDS; micro-Raman Spectroscopy, μRS; gas chromatography-mass spectrometry, GC-MS) were applied to determine the chemical nature and the state of conservation of the "artistic" and natural patinas visible on the Virtues surfaces. Some patination tests were performed taking into account the collected analytical data and the indications provided by the scientific literature and the historical documents. The combination of the results obtained through the scientific investigations and the experimental work allowed for supposing the materials and the patination technique selected by the artist to adorn the sculptures and providing indications for the correct conservation of the six sculptures.

    Research on psychological risk factors for injury has focused on stable traits. Our objective was to test the feasibility of a prospective longitudinal study designed to examine labile psychological states as risk factors of injury. We measured psychological traits at baseline (mood, ways of coping and anxiety), and psychological states every day (1-item questions on anxiety, sleep, fatigue, soreness, self-confidence) before performances in Cirque du Soleil artists of the show "O". Additional questions were added once per week to better assess anxiety (20-item) and mood. Questionnaires were provided in English, French, Russian and Japanese. Injury and exposure data were extracted from electronic records that are kept as part of routine business practices. The 43.9% (36/82) recruitment rate was more than expected. Most artists completed the baseline questionnaires in 15 min, a weekly questionnaire in <2 min and a daily questionnaire in <1 min. We improved the formatting of some questions during the study, and adapted the wording of other questions to improve clarity. There were no dropouts during the entire study, suggesting the questionnaires were appropriate in content and length. Results for sample size calculations depend on the number of artists followed and the minimal important difference in injury rates, but in general, preclude a purely prospective study with daily data collection because of the long follow-up required. However, a prospective nested case-crossover design with data collection bi-weekly and at the time of injury appears feasible. A prospective study collecting psychological state data from subjects who train and work regularly together is feasible, but sample size calculations suggest that the optimal study design would use prospective nested case-crossover methodology.

  1. A Survey of Artistic Value: From Analytic Philosophy to Neurobiology

    Directory of Open Access Journals (Sweden)

    Zachary P. Norwood

    2013-12-01

    Full Text Available Analytic philosophers have disputed the nature of “artistic value” for over six decades, bringing much needed clarity and rigor to a subject discussed with fashionable obscurity in other disciplines. This essay frames debates between analytic philosophers on artistic value and suggests new directions for future research. In particular, the problem of “intrinsic value” is considered, that is, whether a work’s value derives from its experienced properties, as a work of art, or from cultural trends outside the work’s properties. It is argued that neurobiological research helps resolve perceived differences between a work’s intrinsic and extrinsic values. A work can be both rewarding and punishing on its own, “intrinsic” merit—as a percipient, real thing in the world evoking predictable kinds of emotion—and with respect to ever shifting, “extrinsic” cultural norms.

    Facial reconstruction is employed in the context of forensic investigation and for creating three-dimensional portraits of people from the past, from ancient Egyptian mummies and bog bodies to digital animations of J. S. Bach. This paper considers a facial reconstruction method (commonly known as the Manchester method) associated with the depiction and identification of the deceased from skeletal remains. Issues of artistic licence and scientific rigour, in relation to soft tissue reconstruction, anatomical variation and skeletal assessment, are discussed. The need for artistic interpretation is greatest where only skeletal material is available, particularly for the morphology of the ears and mouth, and with the skin for an ageing adult. The greatest accuracy is possible when information is available from preserved soft tissue, from a portrait, or from a pathological condition or healed injury.

    Full Text Available This article explores the artistic event as pedagogical in Visual Education. It lies in the encounter between the Pictorial Turn in education and the pedagogical turn in art. Drawing from Cultural Pedagogy it seeks to cover how and under what conditions an event can be both an educational and artistic event at the same and how are instituted the spaces that promote educational events as aesthetic experiences. In this article it was pointed out conceptual and methodological bases for distinguishing the space of intersection between art and Visual Education and its political and cultural implications: Participant Art, Cultural Pedagogy and their relationships among politics and aesthetics. In this sense it analyzes the crossings of frontiers both in art and education and creates possibilities for an understanding of pedagogy of dissent.

    2011-10-01

    The case of an 82-year-old female with probable Alzheimer's disease (AD), who developed unusual artistic creativity after development of her disease, is described. The possible pathogenetic mechanism is discussed. The patient showed no inclination toward visual arts during her premorbid years. However, 4 years after development of AD suggestive symptoms she started painting beautiful pictures rather impulsively. Some such paintings have been appreciated even by a qualified art expert. Such de novo development of artistic creativity had been described earlier in subjects with the semantic form of fronto-temporal dementia (FTD), but not in AD. The prevailing concept of lateralized compromise and paradoxical functional facilitation, proposed in connection with FTD subjects, may not be applicable in AD subjects where the affection is more diffuse and more posterior in the brain. Hence, the likely pathogenetic mechanism involved in the case described may remain uncertain. Possibilities are discussed.

    Automatic item generation (AIG) is a broad class of methods that are being developed to address psychometric issues arising from internet and computer-based testing. In general, issues emphasize efficiency, validity, and diagnostic usefulness of large scale mental testing. Rapid prominence of AIG methods and their implicit perspective on mental testing is bringing painful scrutiny to many sacred psychometric assumptions. This report reviews basic AIG ideas, then presents conceptual foundations, image model development, and operational application to artistic judgment aptitude testing.

    2017-12-01

    As world leaders, climate and energy scientists, and others examine our future climate, new ways of collaborating and communicating across different social sectors are becoming more crucial. What images and stories are evoked when you think about the future of the planet? Storytelling and images are basic tools for artists, and are increasingly recognized as critical tools for scientists, educators, and people interested in communicating science to broader public audiences. Science/arts collaborations have numerous benefits and can be challenging when partners have different lexicons for making sense of the world. This participatory session will explore the benefits and role of science/arts partnerships when communicating and engaging with stakeholders from varying backgrounds. Attendees will develop shared vocabulary and examine collaborative tools that can help both non-artists and non-scientists better communicate about climate change, energy policies, and other topics. For newcomers, this will be a 101 primer to community engagement and using the arts and/or collaborating with artists to reach broader audiences with your work. Experienced attendees will examine their own previous partnerships to reflect on the successes and learn from the challenges. Topics to be covered include: 1) understanding shared values between artists/scientists; 2) clarifying target audiences; and 3) identifying factors and components critical for healthy partnerships across sectors. Theater director and engagement strategist Ashley Sparks leads this interactive session and reflects on learnings from her partnership with the Energy Foundation, the Network for Energy, Water, and Health in Affordable Buildings, and the Natural Resources Defense Council. In partnership with engineers and technical experts she has been leading efforts to create a story bank focused on increasing energy efficiency in affordable multifamily housing.

  10. Automatic gallbladder segmentation using combined 2D and 3D shape features to perform volumetric analysis in native and secretin-enhanced MRCP sequences.

    2017-11-24

    We aimed to develop the first fully automated 3D gallbladder segmentation approach to perform volumetric analysis in volume data of magnetic resonance (MR) cholangiopancreatography (MRCP) sequences. Volumetric gallbladder analysis is performed for non-contrast-enhanced and secretin-enhanced MRCP sequences. Native and secretin-enhanced MRCP volume data were produced with a 1.5-T MR system. Images of coronal maximum intensity projections (MIP) are used to automatically compute 2D characteristic shape features of the gallbladder in the MIP images. A gallbladder shape space is generated to derive 3D gallbladder shape features, which are then combined with 2D gallbladder shape features in a support vector machine approach to detect gallbladder regions in MRCP volume data. A region-based level set approach is used for fine segmentation. Volumetric analysis is performed for both sequences to calculate gallbladder volume differences between both sequences. The approach presented achieves segmentation results with mean Dice coefficients of 0.917 in non-contrast-enhanced sequences and 0.904 in secretin-enhanced sequences. This is the first approach developed to detect and segment gallbladders in MR-based volume data automatically in both sequences. It can be used to perform gallbladder volume determination in epidemiological studies and to detect abnormal gallbladder volumes or shapes. The positive volume differences between both sequences may indicate the quantity of the pancreatobiliary reflux.

  11. Artist Material BRDF Database for Computer Graphics Rendering

    Science.gov (United States)

    Ashbaugh, Justin C.

    The primary goal of this thesis was to create a physical library of artist material samples. This collection provides necessary data for the development of a gonio-imaging system for use in museums to more accurately document their collections. A sample set was produced consisting of 25 panels and containing nearly 600 unique samples. Selected materials are representative of those commonly used by artists both past and present. These take into account the variability in visual appearance resulting from the materials and application techniques used. Five attributes of variability were identified including medium, color, substrate, application technique and overcoat. Combinations of these attributes were selected based on those commonly observed in museum collections and suggested by surveying experts in the field. For each sample material, image data is collected and used to measure an average bi-directional reflectance distribution function (BRDF). The results are available as a public-domain image and optical database of artist materials at art-si.org. Additionally, the database includes specifications for each sample along with other information useful for computer graphics rendering such as the rectified sample images and normal maps.

  12. FEMINIST TO POSTFEMINIST: contemporary biofictions by and about women artists.

    Science.gov (United States)

    Novak, Julia

    2017-01-02

    Biographical novels about historical women artists have been experiencing a veritable boom in recent years. Written mostly by women, they can be understood as women authors' attempts to reach out across time (and often, space) to other "artistic" women whose lives "speak to us" today. It has long been a key insight of historical fiction research that a historical novel reveals more about the time in which it was written than the time in which it is set. As such, it can be assumed that contemporary novels about historical women speak as much to twenty-first-century conceptions of femininity as to particular historical moments of female subjectivity. This paper will compare two novels about historical women artists: Janice Galloway's Clara (2002) about nineteenth-century German pianist Clara Wieck-Schumann and Priya Parmar's Exit the Actress (2011) about Restoration actress Nell Gwyn. While based on historical facts, both these novels use the greater freedom of fiction to depart from biographical conventions. It will be demonstrated that although they resemble each other on the discourse level, employing shifts in the narrative perspective, conspicuous typography, and graphic elements, they differ markedly in the biographical and fictional subgenres in which they participate and, hence, in their gender politics.

  13. The collector library. A training for the artistic 'taste'?

    Full Text Available The paper argues that art collectors leveraged their library as one of the formative places of artistic taste. Acquiring knowledge through books may have helped shaping one’s artistic judgment, usually a mix of both intellective and emotional processes. Based on the Venetian case study of 17th-18th centuries patrician libraries, the paper explores the works used by art collectors in order to increase their discernment and artistic judgment: emblem, hieroglyphic and exempla books served as database of both pictorial and textual symbols which helped decipher paintings’ symbols and scenes. The Venetian libraries’ inventories and catalogues reveal the existence of two distinct phenomena: the inclusion of generic emblem printed books (with rare manuscript exceptions in almost all surveyed libraries and the presence of rare and sometimes costly emblem books, specifically tailored to the collector’s field of interest in several libraries. Moreover, the more professional art collectors shared knowledge and titles in order to cut on expenses, relying on the fact that at least one copy was to be found in Venice.

  14. ARTIST: An International Project Investigating Aerosol Retention in a Ruptured Steam Generator

    International Nuclear Information System (INIS)

    Guentay, S.; Dehbi, A.; Suckow, D.; Birchley, J.

    2002-01-01

    Steam generator tube ruptures (SGTR) with a concurrent stuck open safety relief valve are counted among the risk dominant accident sequences because of the potential for radioactive products to bypass the containment. Owing to the absence of relevant empirical data and the complexity of the geometry and controlling processes, the aerosol removal in the steam generator (SG) tubes and in the secondary side is not well understood. Therefore, little or no credit is usually taken for aerosol retention due to natural processes in the various components of a SG. To help reduce the uncertainties associated with fission product release following an SGTR sequence, the Paul Scherrer Institut has initiated an international experimental project to be performed in the ARTIST (AeRosol Trapping In a Steam generaTor) facility in the time period from 2002 to 2007. The ARTIST test section is a scaled model of a real SG, and is comprised of a 264-tube bundle with a maximum height of 3.8 m, as well as one full-size droplet separator and one full-size steam dryer. The ARTIST facility is capable of producing soluble and insoluble aerosols and entrain them at sonic gas flow rates (up to 0.25 kg/s, thus matching comparable values predicted by the codes. In addition, aerosols can be generated at prototypical concentrations (up to 5 g/m 3 ) and sizes (0.2-5 mm AMMD). State of the art instrumentation is used (Low-pressure impactors, photometers, on-line particle sizer, online droplet sizer, etc.). The ARTIST project will simulate the flow and retention of aerosol-borne fission products in the SG, and provide a unique database to support safety assessments and analytical models. The project is foreseen in seven phases: 1) Aerosol retention in the tube under dry secondary side conditions, 2) Aerosol retention in the near field close to break under dry conditions, 3) Aerosol retention in the bundle far field under dry conditions, 4) Aerosol retention in the separator and dryer under dry

This paper attempts to focus on Kurkov’s unique literary characteristics in the unusual combination of deceptive simplicity of style and the profound insights, coupled with acrid ridicule and subtle narration, which can all be attributed to the characteristics of “the Absurdist School”. The writer regards his living condition, as the report from Kiev shows, as kind of dilemma, or paradox: on the one hand, he feels frustrated with Russia intellectually despite the affinity to traditional culture in emotion; on the other hand, he feels more indignant about the European Union who brought painful experiences to his country and his people, in spite of his closeness to western culture and political system.

    The study presents the emancipation of the artworks of psychiatric patients through the review of four centuries, focusing on some of the most important medical cultural and art historical stages of the period between the 18th and the 21st century, which is a particularly relevant era in this regard. It touches on the collections linked to psychiatrists and hospitals that were formed primarily on the basis of the researches that were analyzing the connection between creativity and mental illness. After that, the study discusses the ever-changing attitudes and preferences of artists' and major artistic movements towards psychosis and the pictorial world of the psychotic. With great care, it analyses the aesthetic category of the art brut, which is connected to the French painter Jean Dubuffet and was born in the middle of the 1940s, and the relationship between contemporary art and art brut. In connection with some of the most significant art brut collections and exhibitions, the works of a few classical and contemporary art brut artists are also discussed (Adolf Wolfli, Louis Soutter, Aloise Corbaz, August Walla ).

    2000-04-10

    Psychopathography is a specific kind of biography focusing on psychological and psychopathological aspects of the personality and their significance for creative activity, especially in famous persons. Psychopathography evolved as a discipline from the 1830's onwards, as a product of psychiatry emerging as a science, reflecting its reductionist and nosological approach. An illustration of this method is the analysis of the author E.T.A. Hoffmann, a prototypical representative of the German romanticism at the beginning of the century. Hoffmann himself expresses, in allegorical terms, the menacing, irrational and unconscious domains of the human soul. Romanticism may be seen as a forerunner of the psychoanalytic movement. Confronted with modernism in art, pathographic considerations were to a large extent based upon the object of art itself, often with arrogant and repudiating conclusions concerning the artist. Classical psychoanalysis has had a marked tendency to deduce a great deal about the personality of the artist or the writer solely from analysis of a picture or written text. The pathographic approach of the first century of scientific psychiatry has had a renaissance over the last 15-20 years: The ever increasing interest in affective syndromes has entailed a tendency to trace and identify affective pathology in artists and writers, deceased or alive, often emphasizing the affective dynamics of the creative process, aspects also noted by the classical pathographers. More recent studies of the creative personality may also present improved instruments for the study of the creative process.

    Highlights: ► N-phenylmaleimide-containing branched oligomer has been employed as an additive in lithium cells. ► The branched oligomer additive enhances safety and cycling performance of Li ion battery. ► The highest temperature of branched oligomer-containing battery was only 85 °C in the nail penetration test. - Abstract: In this study, we have investigated N-phenylmaleimide/bismaleimide-containing branched oligomer (BO1) as additive in Li-ion batteries to increase the safety performance by reducing the probability of batteries suffering an internal short circuit. In the nail penetration test, a LiCoO 2 /MCMB full battery with N-phenylmaleimide/bismaleimide-containing branched oligomer (BO1) showed a significant improvement in thermal stability and was able to restrain the temperature of the battery at about 85 °C. Furthermore, we found that N-phenylmaleimide/bismaleimide-containing branched oligomer (BO1) contained battery revealed better cycling and electrochemical performance, compared with the battery with bismaleimide-containing branched oligomer (BO3) in the electrolyte. The improvement might result from the favorable ionic conductivity, Li ion mobility and lower resistance in the battery. This additive can meet the cycling performance and safety requirements for Li-ion batteries.

    1996-12-01

    A 3-dimensional, discrete-feature hydrological model is developed. The model integrates structural and hydrologic data for the Aespoe site, on scales ranging from semi regional fracture zones to individual fractures in the vicinity of the nuclear waste canisters. Predicted parameters for the near field include fracture spacing, fracture aperture, and Darcy velocity at each of forty canister deposition holes. Parameters for the far field include discharge location, Darcy velocity, effective longitudinal dispersion coefficient and head gradient, flow porosity, and flow wetted surface, for each canister source that discharges to the biosphere. Results are presented in the form of statistical summaries for a total of 42 calculation cases, which treat a set of 25 model variants in various combinations. The variants for the SITE-94 Reference Case model address conceptual and parametric uncertainty related to the site-scale hydrogeologic model and its properties, the fracture network within the repository, effective semi regional boundary conditions for the model, and the disturbed-rock zone around the repository tunnels and shafts. Two calculation cases simulate hydrologic conditions that are predicted to occur during future glacial episodes. 30 refs

  4. Behavioral performance follows the time course of neural facilitation and suppression during cued shifts of feature-selective attention.

    Andersen, S K; Müller, M M

    2010-08-03

    A central question in the field of attention is whether visual processing is a strictly limited resource, which must be allocated by selective attention. If this were the case, attentional enhancement of one stimulus should invariably lead to suppression of unattended distracter stimuli. Here we examine voluntary cued shifts of feature-selective attention to either one of two superimposed red or blue random dot kinematograms (RDKs) to test whether such a reciprocal relationship between enhancement of an attended and suppression of an unattended stimulus can be observed. The steady-state visual evoked potential (SSVEP), an oscillatory brain response elicited by the flickering RDKs, was measured in human EEG. Supporting limited resources, we observed both an enhancement of the attended and a suppression of the unattended RDK, but this observed reciprocity did not occur concurrently: enhancement of the attended RDK started at 220 ms after cue onset and preceded suppression of the unattended RDK by about 130 ms. Furthermore, we found that behavior was significantly correlated with the SSVEP time course of a measure of selectivity (attended minus unattended) but not with a measure of total activity (attended plus unattended). The significant deviations from a temporally synchronized reciprocity between enhancement and suppression suggest that the enhancement of the attended stimulus may cause the suppression of the unattended stimulus in the present experiment.

  5. Monuments devoted to artists in public spaces around museums: A nineteenth-century strategy to enhance the urban space of art districts

    Directory of Open Access Journals (Sweden)

    Lorente, J. Pedro

    2014-12-01

    Full Text Available Monuments to kings or military heroes have always been positioned in main squares and avenues, whilst those erected to famous cultural figures were a novelty introduced in the Enlightenment and Romanticism, placing busts or sitting monuments to writers or musicians in secluded gardens and in the surroundings of libraries, theatres, etc. During the nineteenth century, monuments to artists became also a common feature in many cities, where a most likely emplacement for them was in front of some art museum. In a way, they were a complement to the ornaments of such building, usually decorated with portraits and inscriptions glorifying great artists; but the monument to Murillo erected in 1863 by public subscription in Seville's Plaza del Museo was also an urban milestone, catching the attention of promenading public passing along a lateral street. Later, the monuments erected in the piazzas around the Prado Museum in Madrid, or in gardens outside the Louvre, became a popular prototype, emulated in many other cities up to the early 20th century. Their role as interfaces between public spaces and museum sites would thereafter be taken over by other kinds of artistic landmarks: not monuments to artists, but monumental artworks, often owned by the museum itself, thus bringing part of its collection outside, as a welcome starter to prospective cultural consumers.

    Historical and empirical data have linked artistic creativity to depression and other affective disorders. This study examined how vulnerability to experiencing negative affect, measured with biological products, and intense negative emotions influenced artistic creativity. The authors assessed participants' baseline levels of an adrenal steroid (dehydroepiandrosterone-sulfate, or DHEAS), previously linked to depression, as a measure of affective vulnerability. They then manipulated emotional responses by randomly assigning participants to receive social rejection or social approval or to a nonsocial situation. Participants then completed artistic collages, which were later evaluated by artists. Results confirmed a person-by-situation interaction. Social rejection was associated with greater artistic creativity; however, the interaction between affective vulnerability (lower baseline DHEAS) and condition was significant, suggesting that situational triggers of negative affect were especially influential among those lower in DHEAS, which resulted in the most creative products. These data provide evidence of possible biological and social pathways to artistic creativity.

    Full Text Available Technical reproduction in general, and photography in particular have changed the status and practices of art. Similarly, the expansion of Web 2.0 interactive spaces presents opportunities and challenges to artistic communities. Present study focuses on artistic activism: socially sensitive artists publish their creation on the internet on its most interactive space – social media. These artworks carry both artistic and social messages. Such practices force us to reinterpret some elements of the classical art paradigm: its autonomy, authorship, uniqueness (as opposed to copies and series, and the social role of art. The analysis is aimed at Hungarian and Romanian online artistic projects from Transylvania region of Romania, relevant as intercultural communication endeavours. Our research question is the way they differ from the traditional artistic paradigm.

    Full Text Available This study examines the social organisation of Canada’s art world from the standpoint of practising visual artists. Bringing together theories of literacy and institutional ethnography, the article investigates the literacy practices of visual artists, making visible how artists use written texts to participate in public galleries and in the social and institutional relations of the art world. Drawing on extended ethnographic research, including interviews, observational field notes and textual analyses, this study sheds light on the ways visual artists enact particular texts, enact organisational processes, and to enact the social and conceptual worlds they are a part of. Through the lens of visual artists, this study locates two particular texts – the artist statement and the bio statement – in the extended social and institutional relations of the art world.

    Dual tasks with voluntary postural control and calculation have been done by 14 patients (25.7 +/- 4.7 yo.) after traumatic brain injury and 40 healthy volunteers (29.8 +/- 2.5 y.o.). Complex clinical (MMSE, FIM, MPAI-3 and Berg scales) and stabilographic evaluation has been performed. According to clinical evaluation 8 patients were included into group 1 with less severe functional deficit and 6 patients formed group 2 with more severe deficit. Parameters of motor and especially cognitive sub-tasks in patients were lower than in healthy subjects in both separate and dual tasks. In group 2 these parameters were lower than in group 1. Certain types of dual task where the quality of sub-tasks, especially of the motor-one increased in healthy subjects and patients of the first group were revealed. The complex of stabilographic parameters which could be used for estimation of quality of sub-tasks performance has been revealed. Dual tasks could be an additional method of evaluation of patients' adaptive possibilities and certain type of dual task could become a promising approach to recovery at late period of rehabilitation.

    To investigate and compare contrast-enhanced ultrasound (CEUS) in the characterisation of histologically proven focal nodular hyperplasia (FNH) with contrast-enhanced computed tomography (CECT). CEUS was performed in 85 patients with 85 histologically proven FNHs. Enhancement, centrifugal filling, spoke-wheel arteries, feeding artery and central scarring were reviewed and correlated with lesion size or liver background. Independent factors for predicting FNH from other focal liver lesions (FLLs) were evaluated. Forty-seven FLLs with CECT were randomly selected for comparison of diagnostic performance with CEUS. Centrifugal filling was more common (P = 0.002) and the significant predictor (P = 0.003) in FNHs ≤3 cm. Lesion size or liver background has no significant influence on the detection rate of the spoke-wheel arteries and feeding artery (P > 0.05). Central scarring was found in 42.6 % of FNHs ≥3 cm (P = 0.000). The area under the ROC curve, sensitivity and specificity showed no significant differences between CEUS and CECT (P > 0.05), except that the sensitivity of CEUS was better for reader 1 (P = 0.041). CEUS is valuable in characterising centrifugal filling signs or spoke wheels in small FNHs and should be employed as the first-line imaging technique for diagnosis of FNH. (orig.)

    Full Text Available If the great Constantin Stanislavski said that the theatre starts from the cloak-room, today, in the era of broadcasting, we could reformulate the idea, confi rming that the theatre starts with the poster. Posters in the modern variant appeared with the emergence of the printing press. J. Gutenberg’s invention in 1453 became the beginning of the third information revolution, signifying a new stage in the evolution of commercials. Th e poster tradition has taken a new momentum in the nineteenth century. Let us remember such masters as the famous French painter Henri de Toulouse-Lautrec and the Czech Alphonse Mucha (who became popular thanks to the posters with Sarah Bernhardt, and who laid the foundation of the principles of the European theatre poster. The analysis of theatre posters from the Republic of Moldova, certifi es their evolution from text information to the artistic-aesthetic image, from the purely informative image to the suggestive-symbolic one. To exemplify these ideas, we will use posters created for the shows of the „Licurici” and „Guguţă” Puppet Th eatres. Th e authors’ purpose was to present in the foreground of the show the title and the main characters keeping the same style that arouses the attention and curiosity of children. The posters, that promote the meanings and symbols of the message, are increasingly required. So, in a symbolic key, are made the posters for the plays „Swan Flight” (by Andersen, „Făt-Frumos din lacrimă” (by Mihai Eminescu, directed by Nina Zabrodin; „Planeta de rouă” (by Grigore Vieru, directed by Ion Puiu, „Cămașa norocului”, directed by Tatiana Cojocaru etc. Currently the poster (theatre poster has become an art form and submits peculiar artistic regularities and peculiarities, requiring not only a high artistic level of achievement, but also a conceptual one.

  14. Jan Baptist Xavery (1697-1742: A versatile garden artist

    Directory of Open Access Journals (Sweden)

    Dennis de Kool

    2011-04-01

    Full Text Available Dutch garden sculpture from the 18 th century is worthy of more systematic study. Such research may offer valuable insights into the position of garden sculpture within sculpture proper and its meaning in 18 th-century garden art. Jan Baptist Xavery is regarded as one of the most important sculptors working in the Netherlands during the 18 th century. His artistic career, his versatile body of work and his influence on other artists should therefore be studied in more depth. In view of the bloom in garden art in those days Xavery's significance as a 'garden artist' should not be overlooked in such a study. Garden sculptures should not be regarded as independent objects or pure decorative elements, but must be considered within the wider context of garden history. Tragically, many garden ornaments have been removed from their natural green environment. In their new settings they sometimes acquire a new meaning, but more often than not they are not done justice as the original harmonious 'composition' has been lost. As a result, this cultural-historical heritage is often treated indifferently. The few garden sculptures that have survived all calamities and can still be admired in public places are often placed at unsuitable locations and suffer from the weather or vandalism. Many garden sculptures, often damaged, have ended up anonymously in museum depots. Although they are safe there, the dreary catacombs of museums are a far cry from the green surroundings for which they were originally intended. Garden ornaments were, after all, not made for depots but to be looked at, studied and admired by enthusiasts, preferably in green surroundings. Otherwise, they will literally disappear from collective memory. Surely, the talented Jan Baptist Xavery and his contemporaries deserve a better fate than that.

  15. A "next generation" ethics committee. St. Joseph Health system has integrated performance-improvement features into its ethics work.

    Understanding the limitations that accompany the traditional model of ethics committees, St. Joseph Health System (SJHS), Orange, CA, has been working to integrate ethics expertise and quality-improvement methodology into its "Next Generation Model" (NG Model) for such committees. However, moving from a traditional structure to the NG Model (introduced to SJHS facilities in 1999) brought some challenges, not the least of which was a deep-rooted culture of resistance to change. Following a 2004 audit of how the NG model was working, some common challenges were identified. To deal with those challenges, SJHS developed some tools and techniques that have helped ease the ongoing transition. These tools have helped the system's ethics committees address such issues as collaboration for the sake of organizational integration, setting goals, and measuring performance of various ethics roles.

    The gold standard for diagnosis of typhoid fever is blood culture (BC). Because blood culture is often not available in impoverished settings it would be helpful to have alternative diagnostic approaches. We therefore investigated the usefulness of clinical signs, WHO case definition and Widal test for the diagnosis of typhoid fever. Participants with a body temperature ≥37.5°C or a history of fever were enrolled over 17 to 22 months in three hospitals on Pemba Island, Tanzania. Clinical signs and symptoms of participants upon presentation as well as blood and serum for BC and Widal testing were collected. Clinical signs and symptoms of typhoid fever cases were compared to other cases of invasive bacterial diseases and BC negative participants. The relationship of typhoid fever cases with rainfall, temperature, and religious festivals was explored. The performance of the WHO case definitions for suspected and probable typhoid fever and a local cut off titre for the Widal test was assessed. 79 of 2209 participants had invasive bacterial disease. 46 isolates were identified as typhoid fever. Apart from a longer duration of fever prior to admission clinical signs and symptoms were not significantly different among patients with typhoid fever than from other febrile patients. We did not detect any significant seasonal patterns nor correlation with rainfall or festivals. The sensitivity and specificity of the WHO case definition for suspected and probable typhoid fever were 82.6% and 41.3% and 36.3 and 99.7% respectively. Sensitivity and specificity of the Widal test was 47.8% and 99.4 both forfor O-agglutinin and H- agglutinin at a cut-off titre of 1:80. Typhoid fever prevalence rates on Pemba are high and its clinical signs and symptoms are non-specific. The sensitivity of the Widal test is low and the WHO case definition performed better than the Widal test.

    Facebook has established itself as one of the major players in social networking, claiming that it helps members connect and share with the people in their lives. But what if the people you want to connect and share with are your artistic collaborators? Can Facebook be used creatively, as a collaborative artistic environment? This paper explores the creative use of Facebook as a tool for creative collaboration and establishes a number of possible models of artistic collaboration using Facebook.

  18. Art and the brain: the influence of frontotemporal dementia on an accomplished artist.

    Mell, Joshua Chang; Howard, Sara M; Miller, Bruce L

    2003-05-27

    A talented artist developed a progressive aphasia syndrome associated with frontotemporal dementia (FTD). As her disease progressed, language and executive skills declined, but her paintings became freer and more original. She demonstrates that artistic development can occur in the setting of language-dominant types of FTD. The study of artistic development in the setting of FTD suggests that language is not required for, and may even inhibit, certain types of visual creativity.

    The authors explore the psychic passages that were opened up within a patient, Ada, thanks to her contact with two works of art, Signorelli's frescoes in Orvieto and Picasso's painting La Nageuse--their themes, formal structures, and the conventions governing their creation. A work of art can be considered as a kind of window that allows one to look upon the imaginary world created by the artist. One can peer out of this window from the other side, permitting a look at the viewer (the patient), who is caught in a web of associations that are yet to be explored.

    This response to Ian E. Wickramasekera II's article, Mysteries of Hypnosis and the Self Are Revealed by the Psychology and Neuroscience of Empathy, is addressed from a joint perspective on consciousness comprising two related orientations: neuroscience and artistic imagination. We find that the central importance of empathy to empathic involvement theory (Wickramasekera II, 2015) reflects the pivotal nature of empathy in the brain and in the relational exchange implicit in the psychotherapeutic process, particularly when using art in therapy. We offer a preliminary unpacking of the roles related to key psychological processes, such as imagination, that are implicated in clinical uses of verbal and visual empathic resonance.

    The incidence of Achilles tendinopathy is very high in young female gymnasts (17.5 %). According to literature, ecography screenings show the tendons thickening, but at the same time it does not reveal a direct link to the clinical picture. The neovessels are involved in the pathophysiological process of Achilles tendinopathy. For this reason, we wanted to verify there between perfusion tendon values and the type of sport activity. We performed a clinical observational study monitoring the oximetry of the Achilles tendon and the epidemiological data of 52 elite female (artistic and rhythmic) gymnasts versus 21 age-matched controls. Analyzing the main limb, we revealed statistically higher oximetry values in the artistic gymnasts group (69.5 %) compared to the rhythmic gymnasts group (67.1 %) (t = 2.13; p = 0.01) and the sedentary group (66.2 %) (t = 2.70; p = 0.004), but we did not find any differences between rhythmic gymnasts group and the sedentary group (t = 0.68; p = 0.24). The multiple logistic regression model highlighted that the oximetry value of the main limb is not influenced by age, knowledge of the main limb, years of general and gymnastic sports activity (p > 0.05). We discovered an increase of Achilles tendon perfusion in the main limb in the artistic gymnast group. We hypothesize that specific figures of artistic sports activity are responsible for muscle overload and gastrocnemius-soleus group and, at the same time, these figures cause hyperperfusion of the tendon. Prospective longitudinal studies could explain if this could become a predictive sign of the next Achilles tendinopathy onset.

    Musicians' expressive bodily movements can influence observers' perception of performance. Furthermore, individual differences in observers' music and motor expertise can shape how they perceive and respond to music performance. However, few studies have investigated the bodily movements that different observers of music performance perceive as expressive, in order to understand how they might relate to the music being produced, and the particular instrument type. In this paper, we focus on marimba performance through two case studies—one solo and one collaborative context. This study aims to investigate the existence of a core repertoire of marimba performance expressive bodily movements, identify key music-related features associated with the core repertoire, and explore how observers' perception of expressive bodily movements might vary according to individual differences in their music and motor expertise. Of the six professional musicians who observed and analyzed the marimba performances, three were percussionists and experienced marimba players. Following training, observers implemented the Laban effort-shape movement analysis system to analyze marimba players' bodily movements that they perceived as expressive in audio-visual recordings of performance. Observations that were agreed by all participants as being the same type of action at the same location in the performance recording were examined in each case study, then across the two studies. A small repertoire of bodily movements emerged that the observers perceived as being expressive. Movements were primarily allied to elements of the music structure, technique, and expressive interpretation, however, these elements appeared to be interactive. A type of body sway movement and more localized sound generating actions were perceived as expressive. These movements co-occurred and also appeared separately. Individual participant data revealed slightly more variety in the types and locations of actions

    SCinet is the purpose-built network that operates during the International Conference for High Performance Computing,Networking, Storage and Analysis (Super Computing or SC). Created each year for the conference, SCinet brings to life a high-capacity network that supports applications and experiments that are a hallmark of the SC conference. The network links the convention center to research and commercial networks around the world. This resource serves as a platform for exhibitors to demonstrate the advanced computing resources of their home institutions and elsewhere by supporting a wide variety of applications. Volunteers from academia, government and industry work together to design and deliver the SCinet infrastructure. Industry vendors and carriers donate millions of dollars in equipment and services needed to build and support the local and wide area networks. Planning begins more than a year in advance of each SC conference and culminates in a high intensity installation in the days leading up to the conference. The SCinet architecture for SC16 illustrates a dramatic increase in participation from the vendor community, particularly those that focus on network equipment. Software-Defined Networking (SDN) and Data Center Networking (DCN) are present in nearly all aspects of the design.

    In this paper we systematically evaluate the performance of several state-of-the-art local feature detectors and descriptors in the context of longitudinal registration of retinal images. Longitudinal (temporal) registration facilitates to track the changes in the retina that has happened over time. A wide number of local feature detectors and descriptors exist and many of them have already applied for retinal image registration, however, no comparative evaluation has been made so far to analyse their respective performance. In this manuscript we evaluate the performance of the widely known and commonly used detectors such as Harris, SIFT, SURF, BRISK, and bifurcation and cross-over points. As of descriptors SIFT, SURF, ALOHA, BRIEF, BRISK and PIIFD are used. Longitudinal retinal image datasets containing a total of 244 images are used for the experiment. The evaluation reveals some potential findings including more robustness of SURF and SIFT keypoints than the commonly used bifurcation and cross-over points, when detected on the vessels. SIFT keypoints can be detected with a reliability of 59% for without pathology images and 45% for with pathology images. For SURF keypoints these values are respectively 58% and 47%. ALOHA descriptor is best suited to describe SURF keypoints, which ensures an overall matching accuracy, distinguishability of 83%, 93% and 78%, 83% for without pathology and with pathology images respectively.

    To evaluate the diagnostic performance of radiography for the detection of MRI-detected osteoarthritis-associated features in various articular subregions of the hip joint. Forty-four patients with chronic hip pain (mean age, 63.3 ± 9.5 years), who were part of the Hip Osteoarthritis MRI Scoring (HOAMS) cohort, underwent both weight-bearing anteroposterior pelvic radiography and 1.5 T MRI. The HOAMS study was a prospective observational study involving 52 subjects, conducted to develop a semiquantitative MRI scoring system for hip osteoarthritis features. In the present study, eight subjects were excluded because of a lack of radiographic assessment. On radiography, the presence of superior and medial joint space narrowing, superior and inferior acetabular/femoral osteophytes, acetabular subchondral cysts, and bone attrition of femoral head was noted. On MRI, cartilage, osteophytes, subchondral cysts, and bone attrition were evaluated in the corresponding locations. Diagnostic performance of radiography was compared with that of MRI, and the area under curve (AUC) was calculated for each pathological feature. Compared with MRI, radiography provided high specificity (0.76-0.90) but variable sensitivity (0.44-0.78) for diffuse cartilage damage (using JSN as an indirect marker), femoral osteophytes, acetabular subchondral cysts and bone attrition of the femoral head, and a low specificity (0.42 and 0.58) for acetabular osteophytes. The AUC of radiography for detecting overall diffuse cartilage damage, marginal osteophytes, subchondral cysts and bone attrition was 0.76, 0.78, 0.67, and 0.82, respectively. Diagnostic performance of radiography is good for bone attrition, fair for marginal osteophytes and cartilage damage, but poor for subchondral cysts. (orig.)

    To evaluate the diagnostic performance of radiography for the detection of MRI-detected osteoarthritis-associated features in various articular subregions of the hip joint. Forty-four patients with chronic hip pain (mean age, 63.3 {+-} 9.5 years), who were part of the Hip Osteoarthritis MRI Scoring (HOAMS) cohort, underwent both weight-bearing anteroposterior pelvic radiography and 1.5 T MRI. The HOAMS study was a prospective observational study involving 52 subjects, conducted to develop a semiquantitative MRI scoring system for hip osteoarthritis features. In the present study, eight subjects were excluded because of a lack of radiographic assessment. On radiography, the presence of superior and medial joint space narrowing, superior and inferior acetabular/femoral osteophytes, acetabular subchondral cysts, and bone attrition of femoral head was noted. On MRI, cartilage, osteophytes, subchondral cysts, and bone attrition were evaluated in the corresponding locations. Diagnostic performance of radiography was compared with that of MRI, and the area under curve (AUC) was calculated for each pathological feature. Compared with MRI, radiography provided high specificity (0.76-0.90) but variable sensitivity (0.44-0.78) for diffuse cartilage damage (using JSN as an indirect marker), femoral osteophytes, acetabular subchondral cysts and bone attrition of the femoral head, and a low specificity (0.42 and 0.58) for acetabular osteophytes.

  15. The development of real-time stability supports visual working memory performance: Young children's feature binding can be improved through perceptual structure.

    Working memory is a basic cognitive process that predicts higher-level skills. A central question in theories of working memory development is the generality of the mechanisms proposed to explain improvements in performance. Prior theories have been closely tied to particular tasks and/or age groups, limiting their generalizability. The cognitive dynamics theory of visual working memory development has been proposed to overcome this limitation. From this perspective, developmental improvements arise through the coordination of cognitive processes to meet demands of different behavioral tasks. This notion is described as real-time stability, and can be probed through experiments that assess how changing task demands impact children's performance. The current studies test this account by probing visual working memory for colors and shapes in a change detection task that compares detection of changes to new features versus swaps in color-shape binding. In Experiment 1, 3- to 4-year-old children showed impairments specific to binding swaps, as predicted by decreased real-time stability early in development; 5- to 6-year-old children showed a slight advantage on binding swaps, but 7- to 8-year-old children and adults showed no difference across trial types. Experiment 2 tested the proposed explanation of young children's binding impairment through added perceptual structure, which supported the stability and precision of feature localization in memory-a process key to detecting binding swaps. This additional structure improved young children's binding swap detection, but not new-feature detection or adults' performance. These results provide further evidence for the cognitive dynamics and real-time stability explanation of visual working memory development.

    1997-01-01

    An artist's conception of the X-43A Hypersonic Experimental Vehicle, or 'Hyper-X' in flight. The X-43A was developed to flight test a dual-mode ramjet/scramjet propulsion system at speeds from Mach 7 up to Mach 10 (7 to 10 times the speed of sound, which varies with temperature and altitude). Hyper-X, the flight vehicle for which is designated as X-43A, is an experimental flight-research program seeking to demonstrate airframe-integrated, 'air-breathing' engine technologies that promise to increase payload capacity for future vehicles, including hypersonic aircraft (faster than Mach 5) and reusable space launchers. This multiyear program is currently underway at NASA Dryden Flight Research Center, Edwards, California. The Hyper-X schedule calls for its first flight later this year (2000). Hyper-X is a joint program, with Dryden sharing responsibility with NASA's Langley Research Center, Hampton, Virginia. Dryden's primary role is to fly three unpiloted X-43A research vehicles to validate engine technologies and hypersonic design tools as well as the hypersonic test facility at Langley. Langley manages the program and leads the technology development effort. The Hyper-X Program seeks to significantly expand the speed boundaries of air-breathing propulsion by being the first aircraft to demonstrate an airframe-integrated, scramjet-powered free flight. Scramjets (supersonic-combustion ramjets) are ramjet engines in which the airflow through the whole engine remains supersonic. Scramjet technology is challenging because only limited testing can be performed in ground facilities. Long duration, full-scale testing requires flight research. Scramjet engines are air-breathing, capturing their oxygen from the atmosphere. Current spacecraft, such as the Space Shuttle, are rocket powered, so they must carry both fuel and oxygen for propulsion. Scramjet technology-based vehicles need to carry only fuel. By eliminating the need to carry oxygen, future hypersonic vehicles will

    The historical allure of epilepsy transcends academic circles and serves as fascinating critique of the state of the times-its values, judgments, mythos, and people. Immortalized and laid bare in artistic renderings of epilepsy are societal truths, at times both disparately grandiose and grotesque. During the middle ages and Renaissance, the European discourse on epilepsy assumed religious fervor. Epilepsy was considered a demonic machination and its cure an act of divine intercession. A similar theme is found in the artistic depiction of epilepsy from the Inca and Aztec civilizations of that time. After the 19th century drew to a close, the ascendency of empiricism coincided with waning creative interest in epilepsy, with few paintings or pieces to capture insightful perspectives on the illness. In this paper, we review the relationship between art and epilepsy and present two contemporary paintings that convey current western perceptions.

    Full Text Available Rapid advance of location acquisition technologies boosts the generation of trajectory data, which track the traces of moving objects. A trajectory is typically represented by a sequence of timestamped geographical locations. Data visualization is an efficient means to represent distributions and structures of datasets and reveal hidden patterns in the data. In this paper, we explore a cloud model-based method for the generation of stylized renderings of trajectory data. The artistic visualizations of the proposed method do not have the goal to allow for data mining tasks or others but instead show the aesthetic effect of the traces of moving objects in a distorted manner. The techniques used to create the images of traces of moving objects include the uncertain line using extended cloud model, stroke-based rendering of geolocation in varying styles, and stylistic shading with aesthetic effects for print or electronic displays, as well as various parameters to be further personalized. The influence of different parameters on the aesthetic qualities of various painted images is investigated, including step size, types of strokes, colour modes, and quantitative comparisons using four aesthetic measures are also involved into the experiment. The experimental results suggest that the proposed method is with advantages of uncertainty, simplicity and effectiveness, and it would inspire professional graphic designers and amateur users who may be interested in playful and creative exploration of artistic visualization of trajectory data.

    Physician bias toward patients directly impacts patient care and health outcomes. However, too little research has been done investigating avenues to bring about self-awareness in this area to eliminate commonly held stereotypes that fuel physician bias. The purpose of this study was to explore the ways in which 2nd-year medical students' reflected on an artistic-narrative presentation given by a woman with sickle cell disease. A total of 320 2nd-year medical student essays were reviewed for content relevant to the artistic-narrative presentation. A total of 75 essays were identified and served as the data for this study. These 75 essays were analyzed using qualitative interpretive thematic content analysis to identify students' perceptions and reflections on culture in the healthcare environment and the patient-provider relationship. The analysis of the reflective essays revealed that this exercise helped students acknowledge physician bias in pain treatment, foster empathetic views toward patients as individuals, and recognize various ways in which biased beliefs can provide incite in healthcare disparities. These findings suggest that the combination of methods--art, narrative, and written reflection--helped students acknowledge their own bias as well as the ways in which taken-for-granted assumptions and biases can influence patient care.

    Full Text Available Waria or transgender is one of the key population which has a significant role in the success of HIV/AIDS prevention program in East Java. It is estimated that the biggest waria community is in East Java, particularly in Surabaya. The main objective of this research is improving capacity building of ludruk artist waria through HIV/AIDS prevention program. The study has two objectives; firstly to find the effective strategies in improving waria’s feminine skills such as knitting, hair dressing. Secondly to find the effective programs both on-stage and off-stage to improve the quality of ludruk performance such as revitalizing their marketing management, using social media to promote their schedule to the young generation. Some inportant points can be conluded from this study. Firstly, integrated coordinating system between ludruk artist waria and waria communities such as Perwakos and Iwama should be improved. HIV/AIDS prevention programs become uneffective without coordination. In this point, ludruk artist waria need to know that HIV/AIDS prevention programs such as VCT, HIV testing is free of charge. Secondly, in terms of management internal system, ludruk needs to revitalize the content of the story in their performance to be more compatible with the younger audience. To do so, the cooperation is needed among all the stakeholeders to make ludruk survive in the capitalist industrial show business in Indonesia.Salah satu populasi kunci yang memberi kontribusi tingginya prevalensi HIV dan AIDS di JATIM adalah komunitas waria karena di propinsi ini estimasi jumlah waria terbesar di Indonesia. Penelitian ini akan membahas bagaimana waria seniman ludruk dilibatkan dalam pencegahan HIV/AIDS. Program yang telah dilakukan adalah revitalisasi baik on-stage (diatas panggung dan off-stage (di luar panggung. On-stage memfokuskan pada upaya revitalisasi pertunjukan ludruk dengan sistem dan manajemen pertunjukan yang lebih modern, menarik penonton generasi

    When left untreated, age-related macular degeneration (AMD) is the leading cause of vision loss in people over fifty in the US. Currently it is estimated that about eight million US individuals have the intermediate stage of AMD that is often asymptomatic with regard to visual deficit. These individuals are at high risk for progressing to the advanced stage where the often treatable choroidal neovascular form of AMD can occur. Careful monitoring to detect the onset and prompt treatment of the neovascular form as well as dietary supplementation can reduce the risk of vision loss from AMD, therefore, preferred practice patterns recommend identifying individuals with the intermediate stage in a timely manner. Past automated retinal image analysis (ARIA) methods applied on fundus imagery have relied on engineered and hand-designed visual features. We instead detail the novel application of a machine learning approach using deep learning for the problem of ARIA and AMD analysis. We use transfer learning and universal features derived from deep convolutional neural networks (DCNN). We address clinically relevant 4-class, 3-class, and 2-class AMD severity classification problems. Using 5664 color fundus images from the NIH AREDS dataset and DCNN universal features, we obtain values for accuracy for the (4-, 3-, 2-) class classification problem of (79.4%, 81.5%, 93.4%) for machine vs. (75.8%, 85.0%, 95.2%) for physician grading. This study demonstrates the efficacy of machine grading based on deep universal features/transfer learning when applied to ARIA and is a promising step in providing a pre-screener to identify individuals with intermediate AMD and also as a tool that can facilitate identifying such individuals for clinical studies aimed at developing improved therapies. It also demonstrates comparable performance between computer and physician grading. Copyright © 2017 Elsevier Ltd. All rights reserved.

  4. War and Peace: 200 Years of Australian-German Artistic Relations

    2015-04-01

    Full Text Available An overview of Australian-German Artistic Relations over the past two hundred years. The guns were barely silent on the Western Front when on 23 November 1918 Belgian-born Henri Verbrugghen took to the stage of the recently established NSW Conservatorium and softly tapped his baton, bringing the audience to silence. Then into this silence Verbrugghen called down the immortal opening chords of Beethoven’s Ninth Symphony, the ‘Choral’, with its celebrated fourth movement ‘Ode to Joy’, based on Schiller’s words. A difficult piece to stage because of the considerable orchestral forces required, the performance was nevertheless a triumph, and all the more so for the occasion it marked, the Allied victory over Germany. Due to the long lead time and the necessity for extensive rehearsal, its being played at the signing of peace was a coincidence, but nevertheless a very serendipitous one.

    2014-01-01

    In a study of three indigenous and non-indigenous cultural groups in northwestern and northeastern Siberia, framed line tests and a landscape drawing task were used to examine the hypotheses that test-based assessments of context sensitivity and independence are correlated with the amount of contextual information contained in drawings, and with the order in which the focal and background objects are drawn. The results supported these hypotheses, and inspection of the regression relationships suggested that the intergroup variations in test performance were likely to result from differences in the attention accorded to contextual information, as revealed by the drawings. Social and environmental explanations for the group differences in context sensitivity are also discussed. The conclusions support the argument that cultural differences in artistic styles and perceptual tests reflect the same underlying perceptual tendencies, and they are consistent with the argument that these tendencies reflect corresponding differences in patterns of social and environmental interaction.

    Full Text Available Abstract The intensity of emotion and fluctuation of meaning in the poet's mind causes him to go beyond the ordinary language and convey intellectual and emotional meanings through metaphors, similes and linguistic preparations. He has sharp eyes and a sensitive spirit and creative temperament and attempts strengthening his own literary language and creating personal style by inventing novel images, showing the creativity and imagination and entering in various arenas of imagination. This point more than anything else could be done by presenting images and new figures. Perhaps in the sixth century, and especially in Azerbaijani school, more than other periods, poets have been looking for creating innovative style in eloquence. Their major attempts were mainly in imaging, a wide field that they have competed. It is obvious that in this illustration the alphabet letters would be very helpful. Khaghani's Divan of poetry, as one of the greatest poets of this school, is the perfect poetical book of paintings in which meaning has been hidden under a delicate pattern and new different scientific, cultural and religious images. Letters are a broad range of elements that put a new field in front of the poet and he is aware of the potential features of the letters, new images, and artistic creativity techniques as well. This paper shows descriptive - analytical study of various aspects of Khaghani’s poetry and frequency of letters in the alphabet letters, alphabetic-based authenticity of images, different similarity reasons, semantic and literal multi-relevance of letters in the context of poetry, producing figures of speech based on letters, sensational relationship exists between images and letters which have been shown in his poetry. Letter have a double and even multiple application in Khaghani's poetic works (divan and moreover the construction of words and conveying meaning which is the real and common usage, they were used as artistic instruments

    Directory of Open Access Journals (Sweden)

    Robi Kroflič

    2014-03-01

    Full Text Available The key hypothesis of the article is that successful inter-mediation of art to vulnerable groups of people (including children depends on the correct identification of the nature of an artistic act and on the meaning that handicap—as an instance of otherness—has in the life of artists and spectators. A just access to the artistic experience is basically not the question of the distribution of artistic production (since if artistic object is principally accessible to all people, it will not reach vulnerable groups of spectators, but of ensuring artistic creativity and presentation. This presupposes a spectator as a competent being who is able to interact with the artistic object without our interpretative explanation and who is sensible to the instance of otherness (handicap is merely a specific form of otherness. The theory of emancipation from J. Ranciere, the theory of recognition from A. Honneth, and the theory of narration from P. Ricoeur and R. Kearney, as well as our experiences with a comprehensive inductive approach and artistic experience as one of its basic educational methods offer us a theoretical framework for such a model of art inter-mediation.

    2017-11-29

    Psychoactive substance use has often been claimed to help generate and facilitate the artistic creative process. This study explored the role of artists' substance use in their creative processes and their efforts to balance between enhancement and relaxation. Semistructured interviews concerning the artistic creative process and the role of psychoactive substance use were recorded with 72 artists and analyzed using content analysis. The participants were classified according to their substance use in three groups (Cannabis Group, Alcohol Group, and Control Group). Results show that both alcohol and cannabis were used to facilitate creativity and the emotional states that are necessary for the artistic creative process. Participants in the Control group reported that listening to music might function as a mind-altering tool. It was also found that for some artists, substance use is not only characteristic to creation, but it is also part of their everyday lives. Artists are aware of the balancing phenomenon during the artistic creative process. Whether psychoactive substance(s) or other environmental stimuli (such as music) are used to reach the required effect appears to depend upon the individual.
