Sample records for vidicon photographs returned

  1. Landsat 3 return beam vidicon response artifacts

    ,; Clark, B.

    1981-01-01

    The return beam vidicon (RBV) sensing systems employed aboard Landsats 1, 2, and 3 have all been similar in that they have utilized vidicon tube cameras. These are not mirror-sweep scanning devices such as the multispectral scanner (MSS) sensors that have also been carried aboard the Landsat satellites. The vidicons operate more like common television cameras, using an electron gun to read images from a photoconductive faceplate.In the case of Landsats 1 and 2, the RBV system consisted of three such vidicons which collected remote sensing data in three distinct spectral bands. Landsat 3, however, utilizes just two vidicon cameras, both of which sense data in a single broad band. The Landsat 3 RBV system additionally has a unique configuration. As arranged, the two cameras can be shuttered alternately, twice each, in the same time it takes for one MSS scene to be acquired. This shuttering sequence results in four RBV "subscenes" for every MSS scene acquired, similar to the four quadrants of a square. See Figure 1. Each subscene represents a ground area of approximately 98 by 98 km. The subscenes are designated A, B, C, and D, for the northwest, northeast, southwest, and southeast quarters of the full scene, respectively. RBV data products are normally ordered, reproduced, and sold on a subscene basis and are in general referred to in this way. Each exposure from the RBV camera system presents an image which is 98 km on a side. When these analog video data are subsequently converted to digital form, the picture element, or pixel, that results is 19 m on a side with an effective resolution element of 30 m. This pixel size is substantially smaller than that obtainable in MSS images (the MSS has an effective resolution element of 73.4 m), and, when RBV images are compared to equivalent MSS images, better resolution in the RBV data is clearly evident. It is for this reason that the RBV system can be a valuable tool for remote sensing of earth resources.Until recently

    The main goal of nuclear safety is to protect from accidents in nuclear power plant (NPP) against radiation arising during normal operation of nuclear installations, or as a result of accidents on them. The most important task in any activities aimed at the maintenance of NPP is a constant maintenance of the desired level of security and reliability. The periodic non-destructive testing during operation provides the most relevant criteria for the integrity of the components of the primary circuit pressure. The objective of this study is to develop a system for forming a color image on the television camera on vidicon which is used to conduct non-destructive testing in conditions of increased radiation at NPPs.

    Routine photography of all patients admitted to the West of Scotland Regional Burns Unit was introduced in 2003. To date, there are few burns units to evaluate the usefulness of photographs taken. To assess the usefulness of photographs of patients admitted to the burns unit to various members of the multidisciplinary team. A questionnaire was completed by hospital staff involved in the management of burns patients over a 3-month period. A total of 43 questionnaires were completed. The majority of questionnaires were completed by nursing staff (55%) followed by medical staff (23%); physiotherapy (5%); anaesthetists (7%); theatre staff (5%); students (2%); dietician (2%). About 98% of respondents agreed that photographs were useful overall, particularly for teaching purposes. About 9% disagreed that photographs were useful for assessment due to difficulty in assessing depth of burn. About 72% agreed that the photographs were useful for patient management and improve patient care. About 88% agreed that all patients should have photographs available in future. Advantages of photographs include; moving and handling of patients; patient positioning in theatre; reviewing wound healing and complications. They are useful for assessing site, size and type of burn. Disadvantages include difficulty in assessing depth of burn, technical factors, and unavailability out of hours. Photographs of burns patients are useful overall to all members of the multidisciplinary team.

    Sigmoid (σ-type) structure in mylonite exposed along the wall of the Blue Nile Canyon in Bure, Ethiopian Plateau, Ethiopia. The Blue Nile River carved a 1.6 km deep and extensive canyon on the Ethiopian Plateau and exposed Neoproterozoic to Quaternary rocks. The lenticular-shaped sigmoid is a deformed feldspar aggregate with elongated wings at both ends. The wings of the clast step up in the direction of movement of the upper part of shear zone, thus showing a dextral (right-lateral) sense of shear. This Neoproteozoic-Early Paleozoic shear zone might have formed by dynamic metamorphism during the East African Orogeny, which is related to the collision between East and West Gondwanaland. The horizontal scale bar in the photograph is 5 cm. Outcrop location Bure region (10° 20.326' N, 037°1.305 E, 1580 m altitude). Photograph © Nahid D.

    High speed photography is an excellent source of engineering data but only provides a two-dimensional representation of a three-dimensional event. Multiple cameras can be used to provide data for the third dimension but camera locations are not always available. A solution to this problem is to overlay three-dimensional CAD/CAM models of the hardware being tested onto a film or photographic image, allowing the engineer to measure surface distances, relative motions between components, and surface variations.

    2011-05-01

    Full Text Available This article is a more general "companion" to the subsequent, Brian ROBERTS (2011 "Interpreting Photographic Portraits: Autobiography, Time Perspectives and Two School Photographs". The article seeks to add to the growing awareness of the importance of visual materials and methods in qualitative social research and to give an introduction to the "photographic self image"—self-portraits and portraits. It focuses on time and memory, including the experiential associations (in consciousness and the senses that the self engenders, thus linking the "visual" (photographic and "auto/biographical". The article attempts to "map" a field—the use of portraiture within social science—drawing on narrative and biographical research, on one side, and photographic portraiture, on the other. In supporting the use of photography in qualitative research it points to the need for researchers to have a greater knowledge of photographic (and art criticism and cognisance of photographic practices. The article does not intend to give a definitive account of photographic portraiture or prescribe in detail how it may be used within social science. It is an initial overview of the development and issues within the area of photographic portraiture and an exploration of relevant methodological issues when images of individuals are employed within social science—so that "portraiture" is better understood and developed within biographical and narrative research.

    Nursing students' exposure to clinical placements with older adults is instrumental in helping them adopt positive attitudes toward care of that population. This qualitative pilot study analyzed perceptions and expectations of a group of first-year students prior to a clinical placement with older adults. A photo-elicitation technique, involving viewing of realistic photographs of older adults being cared for, was used to help students clarify expectations. This was followed by thematic analysis of their perceptions and expectations. Analysis revealed five main themes: Dissecting What It Means to Be a Nurse, Revisioning Therapeutic Relationships in Terms of Dignity, Youthful Reflection on the Differences Between Young and Old, Feeling Challenged and Confronted, and Experiencing Sensitivity and Awkwardness Toward Older Adults' Nakedness. Engagement with images of older adults encouraged students to anticipate their clinical placement in an aged care setting in a more meaningful, reflective way than they may have done without prior exposure, suggesting a need for realistic pre-practice education.

    Full Text Available Merely rhetorically and answering in the negative, Kendall Walton has asked: "Isn't photography just another method people have of making pictures, one that merely uses different tools and materials; cameras, photosensitive paper, and darkroom equipment, rather than canvas, paint, and brushes? And don't the results differ only contingently and in degree, not fundamentally, from pictures of other kinds?" Contrary to Walton and others, I answer with a resounding "Yes" to Walton’s questions in this article. It is a widely shared view that photographs are somehow special and that they fundamentally differ from hand-made pictures such as paintings, both from a phenomenological point of view (in the way we experience them and an epistemic point of view (since they are supposed to have a different that is, greater, epistemic value from paintings that gives us a privileged access to the world. I almost reject the totality of these claims and, as a consequence, there remains little difference between photographs and paintings. As we shall see, “photographs are always partly paintings,” a claim that is true not only of retouched digital photographs but of all photographs, including traditional ones made using photosensitive film and development techniques.

    Deblurring capabilities would significantly improve the scientific return from Space Shuttle crew-acquired images of the Earth and the safety of Space Shuttle missions. Deblurring techniques were developed and demonstrated on two digitized images that were blurred in different ways. The first was blurred by a Gaussian blurring function analogous to that caused by atmospheric turbulence, while the second was blurred by improper focussing. It was demonstrated, in both cases, that the nature of the blurring (Gaussian and Airy) and the appropriate parameters could be obtained from the Fourier transformation of their images. The difficulties posed by the presence of noise necessitated special consideration. It was demonstrated that a modified Wiener frequency filter judiciously constructed to avoid over emphasis of frequency regions dominated by noise resulted in substantially improved images. Several important areas of future research were identified. Two areas of particular promise are the extraction of blurring information directly from the spatial images and improved noise abatement form investigations of select spatial regions and the elimination of spike noise.

    This paper on providing "oo-information" (= objective object-information) on cultural monuments and sites, based on 3D photographs is also a contribution of CIPA task group 3 to the 2013 CIPA Symposium in Strasbourg. To stimulate the interest in 3D photography for scientists as well as for amateurs, 3D-Masterpieces are presented. Exemplary it is shown, due to their high documentary value ("near reality"), 3D photography support, e.g. the recording, the visualization, the interpretation, the preservation and the restoration of architectural and archaeological objects. This also includes samples for excavation documentation, 3D coordinate calculation, 3D photographs applied for virtual museum purposes and as educational tools. In addition 3D photography is used for virtual museum purposes, as well as an educational tool and for spatial structure enhancement, which in particular holds for inscriptions and in rock arts. This paper is also an invitation to participate in a systematic survey on existing international archives of 3D photographs. In this respect it is also reported on first results, to define an optimum digitization rate for analog stereo views. It is more than overdue, in addition to the access to international archives for 3D photography, the available 3D photography data should appear in a global GIS(cloud)-system, like on, e.g., google earth. This contribution also deals with exposing new 3D photographs to document monuments of importance for Cultural Heritage, including the use of 3D and single lense cameras from a 10m telescope staff, to be used for extremely low earth based airborne 3D photography, as well as for "underwater staff photography". In addition it is reported on the use of captive balloon and drone platforms for 3D photography in Cultural Heritage. It is liked to emphasize, the still underestimated 3D effect on real objects even allows, e.g., the spatial perception of extremely small scratches as well as of nuances in color differences

    Spacelab Life Science -1 (SLS-1) was the first Spacelab mission dedicated solely to life sciences. The main purpose of the SLS-1 mission was to study the mechanisms, magnitudes, and time courses of certain physiological changes that occur during space flight, to investigate the consequences of the body's adaptation to microgravity and readjustment to Earth's gravity, and bring the benefits back home to Earth. The mission was designed to explore the responses of the heart, lungs, blood vessels, kidneys, and hormone-secreting glands to microgravity and related body fluid shifts; examine the causes of space motion sickness; and study changes in the muscles, bones, and cells. This photograph shows astronaut Rhea Seddon conducting an inflight study of the Cardiovascular Deconditioning experiment by breathing into the cardiovascular rebreathing unit. This experiment focused on the deconditioning of the heart and lungs and changes in cardiopulmonary function that occur upon return to Earth. By using noninvasive techniques of prolonged expiration and rebreathing, investigators can determine the amount of blood pumped out of the heart (cardiac output), the ease with which blood flows through all the vessels (total peripheral resistance), oxygen used and carbon dioxide released by the body, and lung function and volume changes. SLS-1 was launched aboard the Space Shuttle Orbiter Columbia (STS-40) on June 5, 1995.

    New computer techniques for analyzing and processing photographic images of galaxies are presented, with interesting scientific findings gleaned from the processed photographic data. Discovery and enhancement of very faint and low-contrast nebulous features, improved resolution of near-limit detail in nebulous and stellar images, and relative colors of a group of nebulosities in the field are attained by the methods. Digital algorithms, nonlinear pattern-recognition filters, linear convolution filters, plate averaging and contrast enhancement techniques, and an atmospheric deconvolution technique are described. New detail is revealed in images of NGC 7331, Stephan's Quintet, Seyfert's Sextet, and the jet in M87, via processes of addition of plates, star removal, contrast enhancement, standard deviation filtering, and computer ratioing to bring out qualitative color differences.

    Full Text Available La conservation des documents photographiques peut nécessiter des interventions préventives ou curatives. Ce choix est guidé par leur état de conservation. Une meilleure connaissance des détériorations est donc cruciale. Le répertoire présenté ici essaie de les classifier selon des caractéristiques spécifiques et leur niveau de gravité. Les différents types de dégradation sont illustrés et décrits avec une terminologie précise. L’auteur propose en regard de ceux-ci l’intervention qui semble la plus appropriée. Ce répertoire s’adresse à toutes les personnes concernées par la photographie, qu’ils soient dans le milieu de la conservation ou dans le domaine artistique, dans les musées ou dans les archives. In order to rescue a damaged photographic object, preventive or conservative actions are needed. Knowing the specific characteristics of different types of damage is crucial. A damage atlas can provide these characteristics. With this atlas the damage can be recognised and appropriate actions can be taken. This damage atlas offers a first attempt to such a characterisation in the field of photography. The damage atlas contains images and the necessary information about damage on photographic material. The atlas with special annotations about the terminology and the grade of the damage is meant for everybody who works with photographic material, as well in museums as in archives.

    2015-12-01

    Full Text Available This work introduces Osman Darcan, an important name in the history of Ankara photography studios. Darcan followed in the footsteps of famous Austrian photographer Othmar Pferschy, whom he met in Istanbul, to go on to create his own valuable work. On leaving the Public Press Authority Photo Film Center, where he worked as a newsreel photographer and film operator, in 1943 he began taking photographs at the Tatbikat Theater at the Ankara State Conservatoire, where he continued as the photographer for the State Theater until the end of his life. At the same time, this master photographer took the pictures of a select coterie of Ankara’s leading individuals and well-known performers at a studio he opened on Anafartalar Caddesi. In both these roles, his photographs evoke admiration thanks to Darcan’s professional abilities and level of artistry.

    A survey of the members of the Angle Society of Europe showed that 60% of orthodontists took their own clinical photographs, 35% assigned the task to an auxiliary, and 5% hired professional clinical photographers. It is always useful to ensure that orthodontists' time is used to maximum effect. Clinical photography could be delegated to auxiliary staff. In this study, we assessed the quality of photographs taken by orthodontists to see whether those taken by orthodontic auxiliaries and clinical photographers are of comparable quality. Fifty sets of orthodontic photographs were collected from each of 3 types of photographers: orthodontists, orthodontic auxiliaries, and professional clinical photographers. Four assessors scored each set for quality and detailed errors. The results were compared to determine whether there were differences between the quality of the photographs taken by the different groups. Most of the photos taken by the 3 groups of photographers were judged to be good or acceptable. The results for extraoral photographs showed no statistically significant differences between the 3 groups for good (P = 0.398) and acceptable (P = 0.398) images. The results for intraoral photographs did not differ significantly for acceptable and unacceptable photographs, but orthodontists produced significantly more good-quality intraoral photographs (P = 0.046).

  18. Geologic map of the northern Crisium region. [from Apollo 17 metric photographs

    Wilhelms, D. E.

    1973-01-01

    Apollo 17 metric photographs provide the best available coverage for geologic interpretation of northern Mare Crisium and the northern Crisium basin. One region in particular, between Alhazen Crater and longitude 66 E, had previously been covered very poorly. The Apollo 17 photographs provide excellent monoscopic as well as stereoscopic viewing because of the favorably low sun illuminations (15 deg to 49 deg). These new photographic data allow the geology of the basin, the mare, and other nearby terrains to be reevaluated. This reexamination, together with data from continuing moon-wide photogeologic studies and analyses of returned rocks from Apollo landing sites, has produced a simple evolutionary picture of the region, expressed by fewer map units and explained by fewer basic processes than previously thought necessary.

    Watanabe, Toshio

    2004-04-01

    How can we reproduce real physical depth from a photograph? How does depth perception in the photograph differ from depth perception in the direct observation? In Experiment 1, objects in an open space were photographed and presented on a screen. Subjects were asked to judge the distances from a fixed point to the objects and the angles from the median line. The distances and the angles in the photograph were perceived shorter and larger than in physical space, respectively. Furthermore, depth perception in the photograph had an anisotropic property. In Experiment 2, the same objects as in Experiment 1 were observed directly by the subjects. The distances and the angles in the direct observation were perceived longer and smaller at longer distance than in the photograph, respectively. It was concluded that depth perception in the photograph did not reproduce depth either in physical space or in visual space, but it was closer to depth in visual space than in physical space. Furthermore, photographic space had an anisotropic property as visual space did.

    1998-11-01

    Purpose: It has been hypothesized that photographs can facilitate the interpretation of the radiographic characteristics of trabecular bone. The reliability of these photographic and radiographic approaches has been determined, as have various agreements between the two approaches and their correlations with biomechanical characteristics. Material and Methods: Fourteen vertebral bodies were obtained at autopsy from 6 women and 8 men aged 22-76 years. Photographs (n=28) and radiographs (n=28) were taken of midsagittal slices from the third lumbar vertebra. The radiographs and photographs were digitized and the geometric properties of the trabecular architecture were then determined with a digital images analysis technique. Information on the compressive strength and ash density of the vertebral body was also available. Results: The geometric properties of both radiographs and photographs could be measured with a high degree of reliability (Cronbach`s {alpha}>0.85). Agreement between the radiographic and photographic approaches was mediocre as only the radiographic measurements showed insignificant correlations (p<0.05) with the biomechanical characteristics. We suggest that optical phenomena may result in the significant correlations between the photographs and the biomechanical characteristics. Conclusion: For digital image processing, radiography offers a superior description of the architecture of trabecular bone to that offered by photography. (orig.)

  5. What Makes a Photograph Memorable?

    Science.gov (United States)

    Isola, Phillip; Jianxiong Xiao; Parikh, Devi; Torralba, Antonio; Oliva, Aude

    2014-07-01

    When glancing at a magazine, or browsing the Internet, we are continuously exposed to photographs. Despite this overflow of visual information, humans are extremely good at remembering thousands of pictures along with some of their visual details. But not all images are equal in memory. Some stick in our minds while others are quickly forgotten. In this paper, we focus on the problem of predicting how memorable an image will be. We show that memorability is an intrinsic and stable property of an image that is shared across different viewers, and remains stable across delays. We introduce a database for which we have measured the probability that each picture will be recognized after a single view. We analyze a collection of image features, labels, and attributes that contribute to making an image memorable, and we train a predictor based on global image descriptors. We find that predicting image memorability is a task that can be addressed with current computer vision techniques. While making memorable images is a challenging task in visualization, photography, and education, this work is a first attempt to quantify this useful property of images.

    1994-01-01

    In this photograph, astronaut Carl Walz performs the Performance Assessment Workstation (PAWS) experiment at the flight deck of the Space Shuttle Orbiter Columbia during the STS-65 mission. Present day astronauts are subject to a variety of stresses during spaceflight. These include microgravity, physical isolation, confinement, lack of privacy, fatigue, and changing work/rest cycles. The purpose of this experiment is to determine the effects of microgravity upon thinking skills critical to the success of operational tasks in space. The principle objective is to distinguish between the effects of microgravity on specific information-processing skills affecting performance and those of fatigue caused by long work periods. To measure these skills, the investigators use a set of computerized performance tests called the Performance Assessment Workstation, which is based on current theoretical models of human performance. The tests were selected by analyzing tasks related to space missions and their hypothesized sensitivity to microgravity. Multiple subjective measures of cumulative fatigue and changing mood states are also included for interpreting performance data.

    Automatically quantifying the aesthetic appeal of images is an interesting problem in computer science and image processing. In this paper, we incorporate aesthetic properties and convert them into computable image features for classifying photographs taken by amateur and professional photographers. In particular, color histograms, spatial edge distribution, and repetition identification are used as features. Results of experiments on professional and amateur photograph data sets confirm the discriminative power of these features.

    To describe a novel calibration technique for photographs of different sizes and to test a new method of chin evaluation in relation to established analysis measurements. A photograph analysis and medical record review of 14 patients who underwent combined rhinoplasty and chin correction at an academic center. Patients undergoing concurrent orthognathic surgery, rhytidectomy, or submental liposuction were excluded. Preoperative and postoperative digital photographs were analyzed using computer imaging software with a new method, the soft tissue porion to pogonion distance, and with established measurements, including the cervicomental angle, the mentocervical angle, and the facial convexity angle. The porion to pogonion distance consistently increased after the chin correction procedure (more in the osseous group). All photograph angle measurements changed toward the established normal range postoperatively. Surgery for facial disharmony requires artistic judgment and objective evaluation. Although 3-dimensional video analysis of the face seems promising, its clinical use is limited by cost. For surgeons who use computer imaging software, analysis of profile photographs is the most valuable tool. Even when preoperative and postoperative photographs are of different sizes, relative distance comparisons are possible with a new calibration technique using the constant facial landmarks, the porion and the pupil. The porion-pogonion distance is a simple reproducible measurement that can be used along with established soft tissue measurements as a guide for profile facial analysis.

  19. The return of religion

    Directory of Open Access Journals (Sweden)

    S. Griffioen

    2011-06-01

    Full Text Available Religion is back in Philosophy as a respectable subject. Part 1 first charts what MacIntyre, Taylor and Derrida have meant in this regard. Subsequently, it turns to the Enlightenment to determine what constituted the breakthrough. It is found that even where the Enlightenment gave maximum room to religion i.e. as a civic religion and as “religion of the heart” it still excluded a constitutive relation to a transcendent revelation. Part 2 centres on the religion-faith distinction in reformational philosophy. Similar to the Enlightenment, religion is understood as part of human nature. However, human nature itself is conceived as intrinsically religious and depending for its light on revelation. Secondly, “religion” in this context also encompasses idols and religious substitutes. Thus, it directs attention to shopping malls, football stadiums, health policy, et cetera, as possible contexts of a return of religion. Examples show that this has become a popular approach. However, most of the publications surveyed fail to distinguish between an “analogical” and a “pistically qualified” use of religion, and are open to exaggerations (the shopping mall and football stadiums as temples, etc.. At this junction, the relevance is shown of the religion-faith distinction as well as of Elaine Botha’s theory of metaphors. The epilogue offers an integration of parts one and two.

    This paper describes procedures for taking solar aureole photographs with conventional small format (35- or 70-mm) cameras and films and discusses photographic-photometry techniques for obtaining accurate solar aureole radiance measurements from these photographs, the measurements being used for retrieving atmospheric aerosol characteristics. The photographic data reduction techniques discussed here include sensitometry, densitometry, off-axis illumination distribution measurement, photogrammetry and photometry relations, etc. Comparison tests show that photographic measurements of the solar aureole radiance agree well with simultaneous photoelectric measurements.

    2014-05-01

    To present a new approach for teaching direct ophthalmoscopy to medical students. At the University of Bergen, four consecutive classes of fourth-year medical students complete a required 9-week ophthalmology course every year. In the present project, one fundus photograph was taken of each student. The photographs were randomly numbered, printed on A4 glossy photo paper, and displayed on the classroom wall. Each student was given a form to fill in the fellow students' names matching the number of the fundus photographs. They were encouraged to practise direct ophthalmoscopy on their classmates outside formal teaching hours. At the end of the course, they returned the filled-in forms, and those with the highest number of correct matches between the fundus photographs and fellow students received a reward. Between 2011 and 2013, 239 students completed their ophthalmology course. Of these, 220 students (92%) voluntarily participated in the project. The mean score was 70% correct matches between fundus photographs and fellow students (range 7 - 100%). The students' course evaluations were overall positive. We recommend the use of peer fundus photographs in the context of a learning competition as a simple, inexpensive, and effective way to improve teaching of direct ophthalmoscopy.

  3. [Return to the family].

    Ouaidou, N G

    1993-08-01

    Sahelian countries occupy an inglorious place in the global list of human development. The human development index is superior to the gross national product (GNP) at measuring the progress of a country in terms of development, because it includes income, longevity, and educational level. The highest ranked Sahelian country holds the 114th position out of a 173 countries. The low human development index scores for the Sahel reflects the socioeconomic crisis which has overcome these countries. In 1991, only 3 of 9 Sahelian countries had a mean GP equal or superior to US$500. Just 2 countries had a life expectancy greater than 50 years. In fact, the Sahel had a lower life expectancy than all of Africa (50 years) and much lower than Asia (64 years) and Latin America (67 years). The economic crisis is worse than the cold statistics show. It destabilizes the most disadvantaged populations. The pressure it exerts often leads public authorities to adopt unpopular measures. It depreciates some sociocultural values and disintegrates traditional social structures. It is accentuated by the effects of war and drought. Internal and external migration increases even as urban hope is uncertain. For most people, the family (the traditional framework of individual development) is ready to break apart, leaving only a disincarnate nuclear entity to subsist. Yet, African history is built around the extended family: the place of reproduction, production, distribution, formation, management, perpetuation of demographic behavior, and social control. Senegal and Mali have created ministries which invest in families. The Third African Conference on Population, in 1992, chose its theme to be the relationship between family, population, and sustainable development. It is important to return to the natural or primordial framework--family--as a refuge against the economic crisis.

    It is argued that one of the factors limiting the understanding of return to work (RTW) following work disability is the use of measurement tools that do not capture a complete picture of workers' RTW experiences. To facilitate the investigation of RTW, the current authors proposed a developmental conceptualization of RTW, which argues for an expanded awareness that encompasses four phases: off work, work reintegration, work maintenance and advancement. This paper reports on work undertaken with the aim of operationalizing the conceptualization. A review of the RTW and related literature, with databases searched including PubMed, EconLit, and PsycInfo. We began by extracting details of RTW instruments used by previous researchers. We then interpreted these within the context of the phases of RTW. Using the International Classification of Functioning, Disability, and Health (ICF) to inform our thinking and coding structure, we conceptualized phase-based RTW outcomes and categorized them as 'tasks and actions', 'contextual' or 'process driven'. Iteratively, we reviewed existing instruments for their use as measures of RTW. Where gaps in instrumentation were found, the wider vocational and career assessment literature was searched for instruments that could be adapted for use in RTW research. Results indicate that, although numerous research instruments have been used to assess RTW, within the scientific literature some important dimensions of RTW lack instrumentation. In particular, we found that outcomes such as goal setting, motivation, expectation, job seeking, work maintenance, and career advancement require operationalization. Amongst the outcomes had been operationalized, we found considerable variation in conceptual development and application. The lack of consistency and comprehensiveness of RTW measurement is one of the factors compromising the advancement of the field of RTW research. It is suggested that a more complete and psychometrically sound array of

    Photography is a unique rapidly growing interdisciplinary field encompassing aspects of science, art and technology. Expectations of photographers are steadily increasing with the development of technology. One of the areas playing a crucial role in photography is lighting. Consequently, several types of light sources for photographic use have been developed. The ongoing research in this field concentrates on lamps with tunable CCT (Correlated Color Temperature). In this paper, we present a lamp, which emission spectrum can be tailored without affecting the output luminous ux. Intended for photographic uses, the lamp is based on an integrating sphere and a selection of LEDs. As the LED drivers, DC-DC converters controlled by a Raspberry PI were applied. Design process, including the selection of LED wavelengths, is presented. Output characteristics of the lamp were measured using the setup containing the spectrometer. The results of these experiments show good agreement with the spectrum set on the microcomputer.

    Suzuki, Keiko; Aoki, Naokazu; Kobayashi, Hiroyuki

    A curriculum of an integrated learning using power of photography in the junior highschool was constructed, and was experimented in the class "Seminar for Photographic Expression" of the integrated learning at a junior high school. The center of the curriculum is viewing photographs and self-expression using photography. By comparing the results of questionnaires investigation between before and after the class it is suggested that the curriculum brings about increase in self-esteem, empathy, and motivation for learning. This educational effect is really to foster ability to live self-sufficient lives. On the basis of these results curriculums which can be conducted by anyone at every junior highschool were proposed.

    Full Text Available How can the visual and textual data about an image – the image of a work of art – on recto and verso of a picture be interpreted? An analogical-art-documentary photograph represents a palimpsest to be considered layer by layer. The examples discussed in this article, which refer to both Aby Warburg himself and the first nucleus of the Warburg Institute Photographic Collection, contribute to effectively outline elements of the debate around the question of the photographic reproduction of the work of art as well as of the position of photography in relation to the perception of the work of art.

    The increased demand for high speed data transmission in hybrid-fiber-coax (HFC) networks is putting more pressure to return transmission technology. Most of the current HFC network architectures are optimized for analogue TV signals in the forward path. The assumption is that the same architecture may not be the optimum for return signals. Although the main use for return path is still low bitrate data like Pay-per-View ordering information, network operators are planning and trying the use of high speed cable modems and interactive digital setups. This presentation gives an overview of the alternative solutions used in the reverse path architecture of a modern HFC network.

    This work was performed to advance patient care by protecting patient anonymity. This study aimed to analyze the current practices used in patient facial photograph deidentification and set forth standardized guidelines for improving patient autonomy that are congruent with medical ethics and Health Insurance Portability and Accountability Act. The anonymization guidelines of 13 respected journals were reviewed for adequacy in accordance to facial recognition literature. Simple statistics were used to compare the usage of the most common concealment techniques in 8 medical journals which may publish the most facial photographs. Not applicable. Not applicable. Facial photo deidentification guidelines of 13 journals were ascertained. Number and percentage of patient photographs lacking adequate anonymization in 8 journals were determined. Facial image anonymization guidelines varied across journals. When anonymization was attempted, 87% of the images were inadequately concealed. The most common technique used was masking the eyes alone with a black box. Most journals evaluated lack specific instructions for properly de-identifying facial photographs. The guidelines introduced here stress that both eyebrows and eyes must be concealed to ensure patient privacy. Examples of proper and inadequate photo anonymization techniques are provided.

    2017-07-01

    Full Text Available In today’s world, knowledge is increasingly impacted via visual representation. The messages sent through various sources, such as newspaper, television and the internet, lead people to form opinions about various topics. In this context, photography is one of the most powerful source of information. Moreover, the visual power and the ability to show nonverbal communication makes it a perfect tool for propaganda. These days, photographs showing war themes are used more often than the past. It can be said that war photographs serve as a tool for showing the world the realities of war to those, even to those who turn their back to massacres. After all, a dead body creates a shocking effect in the seer. In this study, the context of the photographs of the war, examined in sample of photograph of Aylan Kurdi, which became the “icon” of immigration due to Syrian civil war and war it relates to and it is studied to understand how it is assessed and understood considering the environment and conditions on the date the photo was taken, existing values, beliefs and things happened in the world in that time, from a critical point of view.

    Full Text Available This paper on providing "oo-information" (= objective object-information on cultural monuments and sites, based on 3D photographs is also a contribution of CIPA task group 3 to the 2013 CIPA Symposium in Strasbourg. To stimulate the interest in 3D photography for scientists as well as for amateurs, 3D-Masterpieces are presented. Exemplary it is shown, due to their high documentary value ("near reality", 3D photography support, e.g. the recording, the visualization, the interpretation, the preservation and the restoration of architectural and archaeological objects. This also includes samples for excavation documentation, 3D coordinate calculation, 3D photographs applied for virtual museum purposes and as educational tools. In addition 3D photography is used for virtual museum purposes, as well as an educational tool and for spatial structure enhancement, which in particular holds for inscriptions and in rock arts. This paper is also an invitation to participate in a systematic survey on existing international archives of 3D photographs. In this respect it is also reported on first results, to define an optimum digitization rate for analog stereo views. It is more than overdue, in addition to the access to international archives for 3D photography, the available 3D photography data should appear in a global GIS(cloud-system, like on, e.g., google earth. This contribution also deals with exposing new 3D photographs to document monuments of importance for Cultural Heritage, including the use of 3D and single lense cameras from a 10m telescope staff, to be used for extremely low earth based airborne 3D photography, as well as for "underwater staff photography". In addition it is reported on the use of captive balloon and drone platforms for 3D photography in Cultural Heritage. It is liked to emphasize, the still underestimated 3D effect on real objects even allows, e.g., the spatial perception of extremely small scratches as well as of nuances in

  11. Green Lightning Channels From the Chaiten Volcano in Chile Photographed By Carlos Gutierrez May 2-3, 2008

    Science.gov (United States)

    Few, A. A.

    2013-12-01

    The two photographs containing the green lightning channels appeared on the Boston.com web site (The Big Picture, June 4, 2008). These web photographs were of limited resolution (176 Kb) making the interpretation of the green channels difficult. The agent for Gutierrez, Landov LLC, made available the two photographs as high resolution digital photographs (1.4 Mb and 1.5 Mb) that appear on the poster. Upon close examination of the green channels it is possible to exclude negative discharges or their remnants as being the source of the green channels; negative discharges require white-hot ionization processes at the leading tip of the channel. There are several examples of the white negative channels on the photographs. The green channels might be positive streamers. In thunderstorms positive streamers propagate within the negative charged region of the cloud collecting electrons, which are supplied to the connected negative discharge channel, hence they are not observed in thunderstorms. They can be detected and mapped inside the thunderstorm from observations of their electromagnetic radiations. Positive streamers are cooler than negative discharges because electrons are convergent on the leading tip of the positive streamer maintaining its conductivity. For the negative leading tips the electrons are divergent and new electrons must be generated by hot ionization processes. A close examination reveals that the green channels track the edge of the ash cloud, which if a positive streamer would indicate a negative surface charge on the cloud. Most likely the green color results from excited oxygen atoms returning to the ground state and emitting a green photon. This is the process that produces the green aurora, and if this produces green lightning, it places several constraints on the conditions of the channel. The two photographs below are selected clips from the much larger photographs; these show the green lightning channels.

    Pilot James M. Kelly (left) and Commander James D. Wetherbee for the STS-102 mission, participate in the movement of supplies inside Leonardo, the Italian Space Agency built Multipurpose Logistics Module (MPLM). In this particular photograph, the two are handling a film magazine for the IMAX cargo bay camera. The primary cargo of the STS-102 mission, the Leonardo MPLM is the first of three such pressurized modules that will serve as the International Space Station's (ISS') moving vans, carrying laboratory racks filled with equipment, experiments, and supplies to and from the Station aboard the Space Shuttle. The cylindrical module is approximately 21-feet long and 15- feet in diameter, weighing almost 4.5 tons. It can carry up to 10 tons of cargo in 16 standard Space Station equipment racks. Of the 16 racks the module can carry, 5 can be furnished with power, data, and fluid to support refrigerators or freezers. In order to function as an attached station module as well as a cargo transport, the logistics module also includes components that provide life support, fire detection and suppression, electrical distribution, and computer functions. The eighth station assembly flight, the STS-102 mission also served as a crew rotation flight. It delivered the Expedition Two crew to the Station and returned the Expedition One crew back to Earth.

  13. The effect of nonprobative photographs on truthiness persists over time.

    Science.gov (United States)

    Fenn, Elise; Newman, Eryn J; Pezdek, Kathy; Garry, Maryanne

    2013-09-01

    When making rapid judgments about the truth of a claim, related nonprobative information leads people to believe the claim-an effect called "truthiness" (Newman, Garry, Bernstein, Kantner, & Lindsay, 2012). For instance, within a matter of seconds, subjects judge the claim "The Mona Lisa has no eyebrows," to be true more often when it appears with a photograph of the Mona Lisa viewed at a distance by a person. But does truthiness persist longer than a few seconds? To determine if truthiness "sticks," we asked people to judge if each trivia claim in a series was true. Half of the claims appeared with nonprobative photos; the rest appeared alone. In a second session 48h later, people returned and made the same judgments about the same statements, but this time, all claims appeared without photos. We found that truthiness "stuck." The magnitude of the effect of photos on subjective feelings of truth was consistent over time. These results fit with those from cognitive and educational psychology, as well as with the related idea that photos make relevant information more available and familiar-and therefore feel more true-even after a delay. © 2013.

    2017-01-01

    Galaxies - the Milky Way's siblings - offer a surprising variety of forms and colours. Displaying symmetrical spiral arms, glowing red nebulae or diffuse halos, even the image of a galaxy can reveal much about its construction. All galaxies consist of gas, dust and stars, but the effects of gravity, dark matter and the interaction of star formation and stellar explosions all influence their appearances. This volume showcases more than 250 of the most beautiful galaxies within an amateur's reach and uses them to explain current astrophysical research. It features fantastic photographs, unique insights into our knowledge, tips on astrophotography and essential facts and figures based on the latest science. From the Andromeda Galaxy to galaxy clusters and gravitational lenses, the nature of galaxies is revealed through these stunning amateur photographs. This well illustrated reference atlas deserves a place on the bookshelves of astronomical imagers, observers and armchair enthusiasts.

  16. Photographic wound documentation after open fracture.

    Science.gov (United States)

    Solan, M C; Calder, J D; Gibbons, C E; Ricketts, D M

    2001-01-01

    More than 3000 open fractures occur in UK each year. They require early assessment and meticulous treatment in order to avoid devastating complications. The British Orthopaedic Association and British Association of Plastic Surgeons Working Party recommend that an instant photograph be taken of an open wound prior to the application of a dressing. The dressing can then remain undisturbed until the definitive surgical debridement is performed in theatre. Such practice reduces nosocomial infection. Fifty-one accident and emergency departments were surveyed by the means of a telephone questionnaire. Forty-one percent were unable to photograph an open fracture wound. A further 20% had no access to a camera outside of office hours. The cheap, simple and effective recommendations of the Working party are not being followed.

    Science.gov (United States)

    Hesselink, L.; White, B. S.

    1983-01-01

    This paper is concerned with the propagation of laser light through a slab of a randomly varying medium. A theoretical analysis is presented which relates the spectrum of the recorded-intensity field some distance downstream of the medium to the spectrum of the index-of-refraction field. For a homogeneous and isotropic random field, the 3-D spectrum of the medium is obtained from the 2-D spectrum of the photograph by dividing each component of the spectrum by the frequency raised to the fourth power. Free-space propagation outside the random medium is accounted for by a scaling factor. Experimental results are presented which support the theoretical analysis. The nonintrusive diagnostic technique presented here is applicable to photographs which contain partially developed caustic networks.

  20. Given time: biology, nature and photographic vision.

    Science.gov (United States)

    Garlick, Steve

    2009-12-01

    The invention of photography in the early 19th century changed the way that we see the world, and has played an important role in the development of western science. Notably, photographic vision is implicated in the definition of a new temporal relation to the natural world at the same time as modern biological science emerges as a disciplinary formation. It is this coincidence in birth that is central to this study. I suggest that by examining the relationship of early photography to nature, we can gain some insight into the technological and epistemological underpinnings of biological vision. To this end, this article is primarily concerned with the role of photographic technology in the genealogy of biological vision. I argue that photography has always been ambiguously located between art and science, between nature and culture, and between life and death. Hence, while it may be a technological expression of the scientific desire to know and to control nature, photographic vision has continually disrupted and frustrated the ambitions of biological technoscience. The technovision of early biological science illustrates that the elusive temporality of nature has always been central to the production of knowledge of life.

  1. Tracking Protests Using Geotagged Flickr Photographs.

    Directory of Open Access Journals (Sweden)

    Merve Alanyali

    Full Text Available Recent years have witnessed waves of protests sweeping across countries and continents, in some cases resulting in political and governmental change. Much media attention has been focused on the increasing usage of social media to coordinate and provide instantly available reports on these protests. Here, we investigate whether it is possible to identify protest outbreaks through quantitative analysis of activity on the photo sharing site Flickr. We analyse 25 million photos uploaded to Flickr in 2013 across 244 countries and regions, and determine for each week in each country and region what proportion of the photographs are tagged with the word "protest" in 34 different languages. We find that higher proportions of "protest"-tagged photographs in a given country and region in a given week correspond to greater numbers of reports of protests in that country and region and week in the newspaper The Guardian. Our findings underline the potential value of photographs uploaded to the Internet as a source of global, cheap and rapidly available measurements of human behaviour in the real world.

    2014-02-01

    Given the growth of Internet photo collections, we now have a visual index of all major cities and tourist sites in the world. However, it is still a difficult task to capture that perfect shot with your own camera when visiting these places, especially when your camera itself has limitations, such as a limited field of view. In this paper, we propose a framework to overcome the imperfections of personal photographs of tourist sites using the rich information provided by large-scale Internet photo collections. Our method deploys state-of-the-art techniques for constructing initial 3D models from photo collections. The same techniques are then used to register personal photographs to these models, allowing us to augment personal 2D images with 3D information. This strong available scene prior allows us to address a number of traditionally challenging image enhancement techniques and achieve high-quality results using simple and robust algorithms. Specifically, we demonstrate automatic foreground segmentation, mono-to-stereo conversion, field-of-view expansion, photometric enhancement, and additionally automatic annotation with geolocation and tags. Our method clearly demonstrates some possible benefits of employing the rich information contained in online photo databases to efficiently enhance and augment one's own personal photographs.

    The sample collection technology and instrument concept for the Sample of Comet Coma Earth Return Mission (SOCCER) are described. The scientific goals of this Flyby Sample Return are to return to coma dust and volatile samples from a known comet source, which will permit accurate elemental and isotopic measurements for thousands of individual solid particles and volatiles, detailed analysis of the dust structure, morphology, and mineralogy of the intact samples, and identification of the biogenic elements or compounds in the solid and volatile samples. Having these intact samples, morphologic, petrographic, and phase structural features can be determined. Information on dust particle size, shape, and density can be ascertained by analyzing penetration holes and tracks in the capture medium. Time and spatial data of dust capture will provide understanding of the flux dynamics of the coma and the jets. Additional information will include the identification of cosmic ray tracks in the cometary grains, which can provide a particle's process history and perhaps even the age of the comet. The measurements will be made with the same equipment used for studying micrometeorites for decades past; hence, the results can be directly compared without extrapolation or modification. The data will provide a powerful and direct technique for comparing the cometary samples with all known types of meteorites and interplanetary dust. This sample collection system will provide the first sample return from a specifically identified primitive body and will allow, for the first time, a direct method of matching meteoritic materials captured on Earth with known parent bodies.

    To determine the preferences of patients with cancer for viewing photographic art in an inpatient hospital setting and to evaluate the impact of viewing photographic art. Quantitative, exploratory, single-group, post-test descriptive design incorporating qualitative survey questions. An academic medical center in the midwestern United States. 80 men (n = 44) and women (n = 36) aged 19-85 years (X = 49) and hospitalized for cancer treatment. Participants viewed photographs via computers and then completed a five-instrument electronic survey. Fatigue, quality of life, performance status, perceptions of distraction and restoration, and content categories of photographs. Ninety-six percent of participants enjoyed looking at the study photographs. The photographs they preferred most often were lake sunset (76%), rocky river (66%), and autumn waterfall (66%). The most rejected photographs were amusement park (54%), farmer's market vegetable table (51%), and kayakers (49%). The qualitative categories selected were landscape (28%), animals (15%), people (14%), entertainment (10%), imagery (10%), water (7%), spiritual (7%), flowers (6%), and landmark (3%). Some discrepancy between the quantitative and qualitative sections may be related to participants considering water to be a landscape. The hypothesis that patients' preferences for a category of photographic art are affected by the psychophysical and psychological qualities of the photographs, as well as the patients' moods and characteristics, was supported. Nurses can play an active role in helping patients deal with the challenges of long hospital stays and life-threatening diagnoses through distraction and restoration interventions such as viewing photographic images of nature. Nurses can use photographic imagery to provide a restorative intervention during the hospital experience. Photographic art can be used as a distraction from the hospital stay and the uncertainty of a cancer diagnosis. Having patients view

    Image display technology has greatly developed over the past few decades, which make it possible to recapture high-quality images from the display medium, such as a liquid crystal display(LCD) screen or a printed paper. The recaptured images are not regarded as a separate image class in the current research of digital image forensics, while the content of the recaptured images may have been tempered. In this paper, two sets of features based on the noise and the traces of double JPEG compression are proposed to identify these recaptured images. Experimental results showed that our proposed features perform well for detecting photographic copying.

  19. Philopatry: A return to origins

    Science.gov (United States)

    Pearce, John M.

    2007-01-01

    The word “philopatry” is a combination of the prefix philo (from the Greekphilos, “beloved”) and the Latin patria, which means “fatherland” or “homeland.” Since the first English-language use of “philopatry” in an ornithological context by Huntington (1951), the term has been applied to two types of site-faithful behavior in birds. Closest to the etymological meaning is the first, “natal philopatry,” which means not dispersing far from, or returning to, a birthplace for reproduction. The second is “breeding philopatry,” which means returning to the same breeding area each year, though that area may not be an individual’s birth place (Shields 1982, Anderson et al. 1992). Therefore, any assessment of breeding philopatry likely includes some immigrant individuals, whereas assessments of natal philopatry include only locally hatched or born individuals.

    Pham, Annette M; Tollefson, Travis T

    2010-05-01

    Facial analysis is an integral part of the surgical planning process. Clinical photography has long been an invaluable tool in the surgeon's practice not only for accurate facial analysis but also for enhancing communication between the patient and surgeon, for evaluating postoperative results, for medicolegal documentation, and for educational and teaching opportunities. From 35-mm slide film to the digital technology of today, clinical photography has benefited greatly from technological advances. With the development of computer imaging software, objective facial analysis becomes easier to perform and less time consuming. Thus, while the original purpose of facial analysis remains the same, the process becomes much more efficient and allows for some objectivity. Although clinical judgment and artistry of technique is never compromised, the ability to perform objective facial photograph analysis using imaging software may become the standard in facial plastic surgery practices in the future.

  6. Silver recovery from spent photographic solutions

    Energy Technology Data Exchange (ETDEWEB)

    Kunda, W.; Etsell, T.H.

    1991-04-12

    A process is disclosed for recovering silver sulfide from a silver-containing spent photographic fixer solution. The process is particularly suited for treating the fixer solution in a manner which enables recycling of the solution, and does not have the inefficiencies and high costs of alternative processes such as electrolysis. The process comprises introducing hydrosulfide ion into the silver-containing spent fixer solution to precipitate silver sulfide. The resultant precipitate is isolated from the fixer solution in order to remove silver from the solution. The process is especially suited for treating spent solutions which contain thiosulfate, in particular sodium or ammonium thiosulfate. The preferred hydrosulfide is either a sodium or ammonium hydrosulfide for precipitating silver in the form of silver sulfide. The quantity of hydrosulfide used is in the range of greater than 0.5 mole per mole of silver in the fixer solution. Experiments are described to illustrate the process of the invention. 3 figs., 5 tabs.

  17. Colorimetric control of photographic prints: the problem of fluorescence

    Science.gov (United States)

    Witt, Klaus

    2002-06-01

    The colorimetric control of photographic prints is an important issue of color reproduction quality. Concentration series of the three photographic dyes Yellow, Magenta and Cyan on photographic paper are very often measured without considering the optical quality of the substrate. However, this substrate, the photographic paper, produces problems for colorimetry because it emits luminenscent light from optical brighteners. Many instruments used in colorimetry are not adapted to measure such an output correctly. Here, an experimental investigation is presented which quantifies systematic shifts of spectral curves and colorimetric values of photographic paper and dyes for various measuring parameters. Several spectrophotometers equipped with different sources for irradiation such as Tungsten halogen lamp, Xenon flash lamp, D65 simulator, and two Xenon lamps with adjustable UV-filter were referenced against the results of two-monochromator spectrophotometer. In the photographic paper the largest color-difference extended to approximately 10 CIELAB-units between irradiation by a Tungsten halogen and a Xenon lamp. These differences diminished with increasing concentration of the photographic dyes, however, did not die away at the highest concentration of the dyes used. The correct colorimetric values for D65 irradiation were halfway between those for the two former lamps and near to measures received from Xenon lamp irraditoin with adjustable UV-filter. Therefore, such spectrophotometers may be used for colorimetric control of photographic prints to attain an accuracy below 3 CIELAB units, or else, two measurements with a Tungsten halogen and a Xenon lamp should be averaged.

  18. Return to sport following amputation.

    Matthews, D; Sukeik, M; Haddad, F

    2014-08-01

    Amputation in athletes has a substantial impact on lifestyle and sporting activity, as well as self-perception and quality of life. The impact of limb loss on athletic ability will vary depending on the cause of amputation and the anatomical location of the amputation. The use of sporting activity for rehabilitation of amputees was first introduced in 1944 at Stoke Mandeville Hospital. The first international paralympic games were founded in 1960. Following these events the opportunity to participate in sport following limb loss has increased significantly. Sport participation has been aided by the development of sporting prostheses, however multiple factors will determine the exact prosthesis used. These include the nature of the sporting activity as well as the level of the amputation. The biomechanics involved in walking and running are altered following the loss of a limb or part thereof. This can cause subsequent degenerative changes within the remaining joints on the amputated limb as well as the contralateral limb. Factors affecting return to sporting activity are multivariate and inter-related, including patient factors, surgical factors, nature and level of the sporting activity and prosthetic factors. The authors review current literature, detail predictive factors of return to sport and the physical and psychosocial impact on patients following limb amputation.

The health of returning migrants is impacted by the cumulative exposure to social determinants and risk factors of health during the migration process, during the return movement, and following return. Circular migration often occurs among the diaspora, which can result in the transfer of knowledge and skills that contribute to development, including health system strengthening. Migrants with dual nationality often return to countries with better health services than their country of origin when they are sick and can not get care at home. To maintain and improve the health of returning migrants, multi-sectoral policies at global and national levels should facilitate access to appropriate and equitable health services, social services, and continuity of care across and within borders.

    Full Text Available Using stock return synchronicity as a measure of a firm’s information environment, our research investigates how the firms’ stock return synchronicity affects analysts’ forecast properties for the accuracy and optimism of the analysts’ annual earnings forecasts. Stock return synchronicity represents the degree to which market and industry information explains firm-level stock return variations. A higher stock return synchronicity indicates the higher quality of a firm’s information environment, because a firm’s stock price reflects more market-level and industry-level information relative to firm-specific information. Our study shows that stock return synchronicity positively affects the forecast properties. Our finding shows that when stock return synchronicity is high, analysts’ annual earnings forecasts are more accurate and less optimistically biased.

  5. Partial Return Yoke for MICE

    Energy Technology Data Exchange (ETDEWEB)

    Witte H.; Plate, S

    2013-05-03

    The international Muon Ionization Cooling Experiment (MICE) is a large scale experiment which is presently assembled at the Rutherford Appleton Laboratory in Didcot, UK. The purpose of MICE is to demonstrate the concept of ionization cooling experimentally. Ionization cooling is an important accelerator concept which will be essential for future HEP experiments such as a potential Muon Collider or a Neutrino Factory. The MICE experiment will house up to 18 superconducting solenoids, all of which produce a substantial amount of magnetic flux. Recently it was realized that this magnetic flux leads to a considerable stray magnetic field in the MICE hall. This is a concern as technical equipment in the MICE hall may may be compromised by this. In July 2012 a concept called partial return yoke was presented to the MICE community, which reduces the stray field in the MICE hall to a safe level. This report summarizes the general concept, engineering considerations and the expected shielding performance.

The S1 truss, attached to the S0 (S Zero) truss, installed by the previous STS-110 mission, flows 637 pounds of anhydrous ammonia through three heat rejection radiators. The truss is 45-feet long, 15-feet wide, 10-feet tall, and weighs approximately 32,000 pounds. The CETA is the first of two human-powered carts that will ride along the railway on the ISS providing a mobile work platform for future extravehicular activities by astronauts.

    Most halftoning algorithms assume there is no interaction between neighboring dots or if there is, it is additive. Without accounting for dot-gain effect, the printed image will not have the appearance predicted by the halftoning algorithm. Thus, there is need to embed a printer model in the halftoning algorithm which can predict such deviations and develop a halftone accordingly. The direct binary search (DBS) algorithm employs a search heuristic to minimize the mean squared perceptually filtered error between the halftone and continuous-tone original images. We incorporate a measurementbased stochastic model for dot interactions of an electro-photographic printer within the iterative DBS binary halftoning algorithm. The stochastic model developed is based on microscopic absorptance and variance measurements. We present an efficient strategy to estimate the impact of 5×5 neighborhood pixels on the central pixel absorptance. By including the impact of 5×5 neighborhood pixels, the average relative error between the predicted tone and tone observed is reduced from around 21% to 4%. Also, the experimental results show that electrophotography-model based halftoning reduces the mottle and banding artifacts.

  10. Equidistant Intervals in Perspective Photographs and Paintings

    Science.gov (United States)

    2016-01-01

    Human vision is extremely sensitive to equidistance of spatial intervals in the frontal plane. Thresholds for spatial equidistance have been extensively measured in bisecting tasks. Despite the vast number of studies, the informational basis for equidistance perception is unknown. There are three possible sources of information for spatial equidistance in pictures, namely, distances in the picture plane, in physical space, and visual space. For each source, equidistant intervals were computed for perspective photographs of walls and canals. Intervals appear equidistant if equidistance is defined in visual space. Equidistance was further investigated in paintings of perspective scenes. In appraisals of the perspective skill of painters, emphasis has been on accurate use of vanishing points. The current study investigated the skill of painters to depict equidistant intervals. Depicted rows of equidistant columns, tiles, tapestries, or trees were analyzed in 30 paintings and engravings. Computational analysis shows that from the middle ages until now, artists either represented equidistance in physical space or in a visual space of very limited depth. Among the painters and engravers who depict equidistance in a highly nonveridical visual space are renowned experts of linear perspective. PMID:27698983

    We introduce the concept, benefits, and general architecture for acquiring, storing, and displaying digital photographs along with medical imaging examinations. We also discuss a specific implementation built around an Android-based system for simultaneously acquiring digital photographs along with portable radiographs. By an innovative application of radiofrequency identification technology to radiographic cassettes, the system is able to maintain a tight relationship between these photographs and the radiographs within the picture archiving and communications system (PACS) environment. We provide a cost analysis demonstrating the economic feasibility of this technology. Since our architecture naturally integrates with patient identification methods, we also address patient privacy issues.

    This paper explores the relationship between modernity and femininity as manifest through the women’s activity, gaze and attire in Marie al-Khazen as well as other photographs taken in the Middle East region between the 1930s and the 1940s. Al-Khazen and the women represented in the photographs of this period were part of a cosmopolitan sensibility that reveals the Middle East region to be far more international than one might have imagined. Caught between projecting a self-image of the cosmopolitan woman and one of the traditional bedouin, these photographs provide a rich field for tracking the ambiguities of the modern.

    2017-01-01

    The multifractality in stock returns have been investigated extensively. However, whether the autocorrelations in portfolio returns are multifractal have not been considered in the literature. In this paper, we detect multifractal behavior of returns of portfolios constructed based on two popular trading rules, size and book-to-market (BM) ratio. Using the multifractal detrended fluctuation analysis, we find that the portfolio returns are significantly multifractal and the multifractality is mainly attributed to long-range dependence. We also investigate the multifractal cross-correlation between portfolio return and market average return using the detrended cross-correlation analysis. Our results show that the cross-correlations of small fluctuations are persistent, while those of large fluctuations are anti-persistent.

  17. Bulgarian Turkish emigration and return.

    Science.gov (United States)

    Vasileva, D

    1992-01-01

    The main factors which determined the 1989 migration of Turks in Bulgaria back to Turkey are discussed. Background history is provided. After World War I, Turks in bulgaria comprised 10% of the total population. Bulgarian policy had been, up to the 1980s to send Rumelian Turks back, but the policy after 1980 was one of a national revival process to integrate Turks into the developed socialist society. Muslim traditions, customs, and Turkish language were interfered with. International disfavor resulted. In May 1989, the Communist Party declared, in an effort to show democratic ideals, open borders. Thus began the new emigration wave. 369,839 people fled to the Turkish border. 43% of the 9.47 ethnic Turks in bulgaria went to Turkey within 4 months. The numbers decreased in November, and soon after the communist regime ended. New laws were adopted allowing Turks to assume their original Turkish names. The huge migration was clearly political, and as such, the emigrant Turks should be determined as refugees and asylum seekers. The provocation of ethnic Turks was used by the communist regime to solve potential social conflicts. Not only did Turks flee to escape from violence or for religious, cultural, and moral reasons but also due to free market initiatives begun in Turkey in the early 1980s which improved Turkish quality of life. Food and consumer goods were cheaper and economic advantages were perceived. Emigrants were primarily peasants with lower levels of education, professional qualifications, and labor skills. 154,937 (42%) returned to bulgaria and 58% stayed in Turkey to comprise 25% of the former Turkish population. During this period, tensions between countries was high.l Bulgarians actively encouraged emigration and Turkey welcomed it. The emigrants to Turkey were seen as foreigners (muhacir or gocmen) but were received with good will and were readily accepted into menial positions. Emigrants were confronted with political, linguistic, and cultural

Parr is a British documentary photographer best known for a direct photographic style that reflects upon “Englishness.”Mexico is his attempt to understand this foreign country via his camera. Mexico, as a research subject, is not a problem to solve but an opportunity to understand a photographer’s work. Parr’s Mexico photography (technique, photographic content, and interest in globalization, economics, and culture is compared to his previous work to explain how Parr uses fashion and icons to represent a culture or class. This article argues Parr’s primary subjects, heads/hats, food, and Christs, are photographed without excessive aesthetic pretensions so that the thrust of Parr’s message about globalization can be more evident:Mexico maintains many of its traditions and icons while adopting American brands.

  9. Trestima – Digital Photographs for Forest Inventory

    Directory of Open Access Journals (Sweden)

    T. Rouvinen

    2014-10-01

    Full Text Available Higher efficiency of forest survey is a corner stone of forest inventory and forest planning. Mobile technologies create a unique opportunity to solve the problem as well as measurement accuracy improvement, higher data objectiveness and independent control of the results. Trestima technology bases on extraction of forest attributes such as basal area, tree stem diameter, tree height and species distribution from photographs captured by a mobile phone. Image processing is performed automatically in a cloud service using machine vision, which is aided by a human operator when necessary. That allows automating all further calculations. Functions of electronic compass and geopositioning implemented on modern smart-phones allows registering the direction as well as sufficiently accurate geographic coordinates, which enables unambiguously association of a measurement and its location. The service produces reports about timber stock, basal area, average diameter, average height, number of tree trunks and diameter distribution. The report prepared for each tree stand includes standard error, as well as confidence interval for the measurements results and the assessment, with a 95 % probability level. Using thecross-section area, the average diameter and average height, the timber stock and the number of stems in the specific area may be calculated. The report generated by Trestima can be easily supplemented by a derived parameters, as well as any of the applicable formulas can be easily modified or altered in accordance with the needs, for example, dependingon the particularforest inventory area. One of the key features of the Trestima technology is the fact that each measurement contains geographic coordinates’ data. It means that, the location of eachmeasurementcan be displayedon the map, and the route, and the area cover under consideration can be analyzed.

    With the increasing abundance of technologies and smart devices, equipped with a multitude of sensors for sensing the environment around them, information creation and consumption has now become effortless. This, in particular, is the case for photographs with vast amounts being created and shared every day. For example, at the time of this writing, Instagram users upload 70 million photographs a day. Nevertheless, it still remains a challenge to discover the "right" information for the appropriate purpose. This paper describes an approach to create semantic geospatial metadata for photographs, which can facilitate photograph search and discovery. To achieve this we have developed and implemented a semantic geospatial data model by which a photograph can be enrich with geospatial metadata extracted from several geospatial data sources based on the raw low-level geo-metadata from a smartphone photograph. We present the details of our method and implementation for searching and querying the semantic geospatial metadata repository to enable a user or third party system to find the information they are looking for.

  17. Maximizing your return on people.

    Bassi, Laurie; McMurrer, Daniel

    2007-03-01

    Though most traditional HR performance metrics don't predict organizational performance, alternatives simply have not existed--until now. During the past ten years, researchers Laurie Bassi and Daniel McMurrer have worked to develop a system that allows executives to assess human capital management (HCM) and to use those metrics both to predict organizational performance and to guide organizations' investments in people. The new framework is based on a core set of HCM drivers that fall into five major categories: leadership practices, employee engagement, knowledge accessibility, workforce optimization, and organizational learning capacity. By employing rigorously designed surveys to score a company on the range of HCM practices across the five categories, it's possible to benchmark organizational HCM capabilities, identify HCM strengths and weaknesses, and link improvements or back-sliding in specific HCM practices with improvements or shortcomings in organizational performance. The process requires determining a "maturity" score for each practice, based on a scale of 1 (low) to 5 (high). Over time, evolving maturity scores from multiple surveys can reveal progress in each of the HCM practices and help a company decide where to focus improvement efforts that will have a direct impact on performance. The authors draw from their work with American Standard, South Carolina's Beaufort County School District, and a bevy of financial firms to show how improving HCM scores led to increased sales, safety, academic test scores, and stock returns. Bassi and McMurrer urge HR departments to move beyond the usual metrics and begin using HCM measurement tools to gauge how well people are managed and developed throughout the organization. In this new role, according to the authors, HR can take on strategic responsibility and ensure that superior human capital management becomes central to the organization's culture.

Esfahan’s poets initiative was considered only in Iran but in other Persian language and literature areas like India, Afghanistan and Transoxiana it was ignored. After the failure of constitutional Movement in Afghanistan, motion similar poetic return was happened that caused poetic themes, which had gone towards modernism, return to Hindi style again.The present paper attempts to analyze the poetic atmosphere in Afghanistan synchronous the poetic return movement in Iran and investigate socio- political backgrounds of return to Hindi style in Afghanistan after constitution failure.

  13. Lewis M. Rutherfurd and the First Photograph of Solar Granulation

    Science.gov (United States)

    Harvey, J. W.; Briggs, John W.; Prosser, Sian

    2017-08-01

    A major astronomical controversy of the mid-19th century was discordant descriptions of the small scale structure of the solar surface. Visual observers contradicted each other by describing the surface as consisting of “corrugations”, “willow leaves”, “rice grains”, “cumuli”, “thatch”, “granules”, etc. Early photographs of the solar surface were not good enough to settle the controversy. The French astronomer Jules Janssen is credited with the first 1876 photographs that clearly showed what we now call solar granulation (1876, CRAS 82, 1363). Upon seeing these images, New Yorker Lewis M. Rutherfurd (1878, MNRAS 38, 410) praised the high quality of Janssen’s images but asserted that he had also photographed granulation as early as 1871 using collodion wet plates. He sent copies of his best photograph to the Royal Astronomical Society to support his assertion. Curious about his claim, Briggs and Harvey set up Rutherfurd’s 13-inch achromatic refractor on Kitt Peak and found that it easily showed well-resolved solar granulation, so his claim might well have been justified. But without his plates we could not confirm the claim. For 140 years the copies of Rutherfurd’s best solar photograph remained in the archives of the Royal Astronomical Society and were recently discovered by Prosser (RAS Photographs A3/001B and A3/002). By coincidence a few days later, Briggs found the original August 11, 1871 plate. Despite poor condition these photographs show solar granulation. There are at least two other possible early claimants (Reade; Vogel) but their plates are almost certainly lost. Rutherfurd was a master of astronomical instrumentation and photography. He was reticent about his work, letting results speak for themselves, so it is satisfying to find that he was justified in making his claim of priority.

  14. Software Programs Derive Measurements from Photographs

    Even under the most unfortunate circumstances, NASA continues on a path of innovation. After the Space Shuttle Columbia reentered the atmosphere on February 1, 2003, it experienced a catastrophic failure, and the entire crew and vehicle were lost. For the two weeks prior to the accident, Columbia STS-107 was on a mission to perform physical, life, and space sciences research in the unique environment of microgravity. Following the accident, the remaining shuttles - Endeavor, Atlantis, and Discovery - were grounded, and an intense investigation ensued. The Columbia Accident Investigation Board spent nearly 7 months examining the cause of the accident and determining what would ensure a safe return to flight. To this end, investigators performed an extensive review down five analytic paths: aerodynamic, thermodynamic, sensor data timeline, debris reconstruction, and imaging. As part of the evaluation of all the available imagery from Columbia's ascent, orbit, and entry, investigators needed a new method for analyzing still video images to determine the size of the material that fell from Columbia, as well as the distance that the material traveled. John Lane, a scientist at Kennedy Space Center, devised a software program to calculate the unknown dimension of the material in the images, and soon after the investigation was complete, continued to enhance the technology. Eventually, the program that assisted in the Columbia investigation became available for licensing.

    The problem of return on current assets and return on working capital related to the cost of equity invested in a company is analyzed in this paper. Risk – return and liquidity – profitability trade-offs influence the company’s equilibrium and management decisions. Liquidity is measured by the cash conversion cycle and it is related to the working capital strategy, measured by current ratio. Rate of return on current assets should be related to the rate of return on working capital that is li...

  16. Effectiveness of Securities with Fuzzy Probabilistic Return

    Directory of Open Access Journals (Sweden)

    Krzysztof Piasecki

    2011-01-01

    Full Text Available The generalized fuzzy present value of a security is defined here as fuzzy valued utility of cash flow. The generalized fuzzy present value cannot depend on the value of future cash flow. There exists such a generalized fuzzy present value which is not a fuzzy present value in the sense given by some authors. If the present value is a fuzzy number and the future value is a random one, then the return rate is given as a probabilistic fuzzy subset on a real line. This kind of return rate is called a fuzzy probabilistic return. The main goal of this paper is to derive the family of effective securities with fuzzy probabilistic return. Achieving this goal requires the study of the basic parameters characterizing fuzzy probabilistic return. Therefore, fuzzy expected value and variance are determined for this case of return. These results are a starting point for constructing a three-dimensional image. The set of effective securities is introduced as the Pareto optimal set determined by the maximization of the expected return rate and minimization of the variance. Finally, the set of effective securities is distinguished as a fuzzy set. These results are obtained without the assumption that the distribution of future values is Gaussian. (original abstract

  17. Stock return distribution in the BRICS

    Directory of Open Access Journals (Sweden)

    George Adu

    2015-12-01

    Full Text Available Stock returns in emerging market economies exhibit patterns that are distinctively different from developed countries: returns are noted to be highly volatile and autocorrelated, and long horizon returns are predictable. While these stylized facts are well established, the assumption underlying the distribution of returns is less understood. In particular, the empirical literature continues to rely on the normality assumption as a starting point, and most asset pricing models tend to overstretch this point. This paper questions the rationale behind this supposition and proceeds to test more formally for normality using multivariate joint test for skewness and kurtosis. Additionally, the paper extends the literature by examining a number of empirical regularities for Brazil, Russia, India, China and South Africa (the BRICS for short. Our main findings are that the distribution of stock returns for the BRICS exhibits peakedness with fatter and longer tails, and this is invariant to both the unit of measurement and the time horizon of returns. Volatility clustering is prevalent in all markets, and this decays exponentially for all but Brazil. The relationship between risk and return is found to be significant and risk premiums are prevalent in our sample.

    Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), and hemiarthroplasty (HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database. All studies relevant to shoulder arthroplasty and return to sport were included. The majority of patients returned to their prior level of activity within six months following TSA, RTSA, and shoulder HA. Noncontact, low demand activities are permitted by most surgeons postoperatively and generally have higher return rates than contact sports or high-demand activities. In some series, patients reported an improvement in their ability to participate in sports following the arthroplasty procedure. The rates of return to sports following TSA (75%-100%) are slightly higher than those reported for HA (67%-76%) and RTSA (75%-85%). Patients undergoing TSA, RTSA, and shoulder HA should be counseled that there is a high probability that they will be able to return to their preoperative activity level within six months postoperatively. TSA has been associated with higher rates of return to sports than RTSA and HA, although this may reflect differences in patient population or surgical indication. PMID:27672564

    Increases in older aged populations and exposure to complicated noise environments have increased the number of hearing-impaired patients, creating greater demands for hearing aids. We have assessed the reasons that individuals rejected wearing and returned properly prescribed hearing aids, as well as differences in individual factors between younger and elderly adults. Of 1138 patients for whom hearing aids were prescribed at Kyung Hee University Medical Center Hearing Aid Clinic, 81 (6.14%) returned their hearing aids, including 36 patients aged hearing-related, and hearing aid-related factors were assessed by retrospective chart analysis and phone survey and compared in the two groups. The primary symptoms reported by the 81 patients who returned their hearing aids were hearing disturbance, ringing, and fullness in the ear, in that order and in both groups. The rate of hearing aid return was similar in elderly females and males (p=0.288). The spondee recognition threshold was significantly higher in younger than in elderly adults (63.3±14.0 dB vs. 55.6±14.74 dB, p=0.019), but the hearing aid return rate was highest in patients with moderate hearing loss in both groups. In evaluating the reasons for return of hearing aids, we found that ineffectiveness of the device was the most frequent reason, accounting for 32.0% of returns, the highest percentage in both groups, with the most frequent patient problem caused by management difficulty in elderly and financial difficulty in younger adults. The reasons for hearing aid return were different in two groups. Financial considerations were cited more by younger adults, while difficulties in managing hearing aids were cited more frequently by elderly adults. Patients in both groups, however, reported that the most frequent reasons for return were inadequate hearing improvement and inconvenience wearing the hearing aid due to noise amplification.

    True objective measures for assessing responsiveness to acne treatments are lacking. Photographic documentation can therefore be a valuable adjunct to treatment assessment. To photographically document the ability of tretinoin microsphere gel (TMG) 0.1% in improving facial acne. A standardized photographic technique was used to assess the efficacy and tolerability of TMG 0.1% applied once nightly for 12 weeks in an open-label trial involving 30 patients (Caucasian and Hispanic) ages 11 to 40 years with moderately severe facial acne. An assessment of frontal, left-sided, and right-sided color photographs at week 12 indicated that TMG 0.1% reduced total, noninflammatory, and inflammatory acne lesion counts by 47.8%, 53.5%, and 33.2%, respectively; and produced an "excellent/ good" investigator's global evaluation (4-point scale) treatment response in 63.6% of patients. Tretinoin microsphere gel 0.1% was well tolerated, and more than 63% of subjects did not exhibit cutaneous adverse effects at week 12. The standardized photographic technique proved to be a useful tool for documenting the efficacy of TMG 0.1% in consistently and significantly improving moderately severe facial acne over a 12-week treatment period.

  2. The analysis of track chamber photographs using flying spot digitizers

    Powell, Brian W

    1966-01-01

    A vast quantity of data pours from the experiments on particle accelerators throughout the world. For example, over 300 000 photographs per week came from the three bubble chambers operating on the CERN PS at the end of 1965. The conventional method of processing these bubble chamber photographs is for each one of them to be examined ('scanned') to see whether it records an interesting particle interaction. The interesting photographs are then passed to hand operated measuring machines to obtain precise measurements of the particle trajectories recorded on the film. Similar measurements are carried out on photographs taken in film spark chamber experiments. This article on the Flying Spot Digitizers at CERN describes one of the most fruitful attempts to speed and make more accurate the process of analysis of bubble and spark chamber photographs. There are two types of Flying Spot Digitizer at CERN — the HPD or Hough Powell Device (named after Professor Hough and the author who, together, initiated the devel...

    A diverse set of photometric, astrometric, spectral and surface brightness data exist on decades of photographic glass plates. The Astronomical Photographic Data Archive (APDA) at the Pisgah Astronomical Research Institute (PARI) was established in November 2007 and is dedicated to the task of collecting, restoring, preserving and storing astronomical photographic data and PARI continues to accept collections. APDA is also tasked with scanning each image and establishing a database of images that can be accessed via the Internet by the global community of scientists, researchers and students. APDA is a new type of astronomical observatory - one that harnesses analog data of the night sky taken for more than a century and making that data available in a digital format.In 2016, APDA expanded from 50 collections with about 220,000 plates to more than 55 collections and more than 340,000 plates and films. These account for more than 30% of all astronomical photographic data in the United States. The largest of the new acquisitions are the astronomical photographic plates in the Yale University collection. We present details of the newly added collections and review of other collections in APDA.

    2015-02-01

    A photograph has been obtained of a natural fifth-order (quinary) rainbow. The photograph was acquired on 8 August 2012 with a digital camera and a polarization filter to maximize contrast of the rainbows with the background. The quinary rainbow, together with its first supernumerary, appears in a contrast-enhanced version of the photograph as broad green and blue-violet color bands within Alexander's dark band between the primary and secondary rainbows. The red band of the quinary rainbow is obscured by the much brighter secondary rainbow. A comparison with a numerical simulation using the Debye series confirms that the color bands of the quinary rainbow appear at the expected location. The numerical simulation produces a good match with the photograph for a droplet radius of 0.46 mm. The green band of the quinary rainbow is even faintly discernible in the unprocessed photograph, suggesting that under exceptional viewing conditions the green band of the quinary rainbow may be observed visually with the aid of a polarization filter.

    Full Text Available This paper examines my effort to document the experiences of a Bhutanese refugee community in a mid-western city of the United States. In particular, the essay looks at housing experiences the community encountered and my efforts to translate the events through photographs. The essay also explores how oppression operates in relation to refugee experiences. Recognizing that knowledge of recent refugees of color has been absent and perhaps may not be addressed in school curriculum in the near future, this photo essay project was created to serve as a curriculum about marginalized communities who are invisible in the curriculum. By using photographs, I explore three concepts that may help us examine the relationship between space and politics: (1 ideal spaces (2 violated spaces (3 damaged spaces. Lastly, by examining refugee experiences, the paper examines pedagogical approaches utilizing photographs to document oppression.

    2010-01-01

    Full Text Available If our main goal is to reconstruct the history of photojournalism in Galicia from the photograph as part of the journalistic discourse, it leads us to confirm some uncertainties that disable a linear story by being unable to construct, much less in the case of a social institution as the press, the period leading to the Second Republic with the long years of dictatorship, nor able to extract a major influence by the photographic practices of the early years of political transition in the subsequent configuration of the role of photojournalism in the media enterprises. This study tries to establish an anthropological link between certain images, to punctuate the signification of the photographic act and, finally, to highlight the value of the act of viewing, and the photos remembered, those images that among all the other images are ours, and we recover them so that other people love them too.

    Grossmann, Michael; Schmidt, Elmar; Haussmann, Alexander

    2011-10-01

    The first likely photographic observation of the tertiary rainbow caused by sunlight in the open air is reported and analyzed. Whereas primary and secondary rainbows are rather common and easily seen phenomena in atmospheric optics, the tertiary rainbow appears in the sunward side of the sky and is thus largely masked by forward scattered light. Up to now, only a few visual reports and no reliable photographs of the tertiary rainbow are known. Evidence of a third-order rainbow has been obtained by using image processing techniques on a digital photograph that contains no obvious indication of such a rainbow. To rule out any misinterpretation of artifacts, we carefully calibrated the image in order to compare the observed bow's angular position and dispersion with those predicted by theory.

    This letter of intent describes a novel and innovative two-phase LAr TPC with photographic capabilities as an attractive alternative readout method to the currently accepted segmented THGEMs which will require many thousands of charge readout channels for kton-scale two-phase TPCs. These colossal LAr TPCs will be used for the future long-baseline-neutrino-oscillation experiments. Optical readout also presents many other clear advantages over current readout techniques such as ease of scalability, upgrade, installation and maintenance, and cost effectiveness. This technology has already been demonstrated at the Liverpool LAr facility with the photographic capturing of cosmic muon tracks and single gammas using a 40-litre prototype. We have now secured ERC funding to develop this further with the ARIADNE programme. ARIADNE will be a 1-ton two-phase LAr TPC utilizing THGEM and EMCCD camera readouts in order to photograph interactions, allowing for track reconstruction and particle identification.

    Returning to both recreational and competitive sport requires the patient demonstrate the ability to perform their activity without pain, without compensation and without apprehension. The primary focus of this article will be to provide progressive weight bearing phased treatment solutions and both objective and empirical return to play testing suggestions. In addition to satisfactorily completing the test battery with maximum effort, the patient must demonstrate the ability to meet the demands for competing within their respective sport specific environment. Returning to competition will most likely include early phase movement screening and clinical clearance followed by late phase athletic and field testing. Hip structure will and must influence training program design. It is therefore important to recognize that indications for return to play must not focus on a single rehabilitation or exercise variable, but rather a combination of clinical, functional and sport specific demands.

In these circumstances, the present article aims to evaluate determinant factors that contribute to the decision of Romanian graduates to return national labour market. We sustain that young Romanians consider carefully and hardly decide their professional future. A particular attention is given to their personal reasons and motivations as well as family and friends network. For designing returning factors we present the results of a questionnaire survey, asking young pupils and students about their future educational way and personal reasons underlying the decision to study in a foreign country and taking into consideration the returning decision. As far international student migration is seen as a first step to migration for work, our work desires to fight for returning home of Romanian well-educated graduates.

    Human identification has been studied since fourteenth century and it has gradually advanced for forensic purposes. Traditional methods such as dental, fingerprint, and DNA comparisons are probably the most common techniques used in this context, allowing fast and secure identification processes. But, in circumstances where identification of an individual by fingerprint or dental record comparison is difficult, palatal rugae may be considered as an alternative source of material. The present study was done to evaluate the individualistic nature and use of palatal rugae patterns for personal identification and also to test the efficiency of computerized software for forensic identification by photographic superimposition of palatal photographs obtained from casts. Two sets of Alginate impressions were made from the upper arches of 100 individuals (50 males and 50 females) with one month interval in between and the casts were poured. All the teeth except the incisors were removed to ensure that only the palate could be used in identification process. In one set of the casts, the palatal rugae were highlighted with a graphite pencil. All the 200 casts were randomly numbered, and then, they were photographed with a 10.1 Mega Pixel Kodak digital camera using standardized method. Using computerized software, the digital photographs of the models without highlighting the palatal rugae were overlapped over the images (transparent) of the palatal rugae with highlighted palatal rugae, in order to identify the pairs by superimposition technique. Incisors were remained and used as landmarks to determine the magnification required to bring the two set of photographs to the same size, in order to make perfect superimposition of images. The result of the overlapping of the digital photographs of highlighted palatal rugae over normal set of models without highlighted palatal rugae resulted in 100% positive identification. This study showed that utilization of palatal photographs

    To objectively evaluate treatment outcomes in oral and maxillofacial surgery, pre- and post-treatment 3-dimensional (3D) photographs of the patient's face can be registered. For clinical use, it is of great importance that this registration process is accurate (registration procedures. Fifteen volunteers (7 males, 8 females; mean age, 23.6 years; range, 21 to 26 years) were invited to participate in this study. Three-dimensional photographs were captured at 3 different times: baseline (T(0)), after 1 minute (T(1)), and 3 weeks later (T(2)). Furthermore, a 3D photograph of the volunteer laughing (T(L)) was acquired to investigate the effect of facial expression. Two different registration methods were used to register the photographs acquired at all different times: surface-based registration and reference-based registration. Within the surface-based registration, 2 different software packages (Maxilim [Medicim NV, Mechelen, Belgium] and 3dMD Patient [3dMD LLC, Atlanta, GA]) were used to register the 3D photographs acquired at the various times. The surface-based registration process was repeated with the preprocessed photographs. Reference-based registration (Maxilim) was performed twice by 2 observers investigating the inter- and intraobserver error. The mean registration errors are small for the 3D photographs at rest (0.39 mm for T(0)-T(1) and 0.52 mm for T(0)-T(2)). The mean registration error increased to 1.2 mm for the registration between the 3D photographs acquired at T(0) and T(L). The mean registration error for the reference-based method was 1.0 mm for T(0)-T(1), 1.1 mm for T(0)-T(2), and 1.5 mm for T(0) and T(L). The mean registration errors for the preprocessed photographs were even smaller (0.30 mm for T(0)-T(1), 0.42 mm for T(0)-T(2), and 1.2 mm for T(0) and T(L)). Furthermore, a strong correlation between the results of both software packages used for surface-based registration was found. The intra- and interobserver error for the reference

    Previous studies on transnationalism have looked at ‘remittances’ and ‘short-term visits’ to the home community and its transformational impact. However, little attention has been given to how transnational links enable return migrants to economically reintegrate into the home community. Although transnationalism describes return migration as a circular movement, there is still evidence of permanent return. Using Ghana as an example, this paper examines the conditions, strategi...

  16. RETURN ON CURRENT ASSETS, WORKING CAPITAL AND REQUIRED RATE OF RETURN ON EQUITY

    Directory of Open Access Journals (Sweden)

    Monika Bolek

    2014-08-01

    Full Text Available The problem of return on current assets and return on working capital related to the cost of equity invested in a company is analyzed in this paper. Risk – return and liquidity – profitability trade-offs influence the company’s equilibrium and management decisions. Liquidity is measured by the cash conversion cycle and it is related to the working capital strategy, measured by current ratio. Rate of return on current assets should be related to the rate of return on working capital that is linked to the cost of capital and the required rate of return. The results indicate that there is a positive relationship between the return on current assets and cash conversion cycle, a positive relationship between cost of equity and return on working capital meaning that the working capital, cash conversion cycle and current assets management are related to profitability, and cost of equity is determined by the required rate of return calculated based on the Capital Asset Pricing Model.

  17. Temporal Oculomotor Inhibition of Return and Spatial Facilitation of Return in a Visual Encoding Task

    Directory of Open Access Journals (Sweden)

    Steven G Luke

    2013-07-01

    Full Text Available Oculomotor inhibition of return (O-IOR is an increase in saccade latency prior to an eye movement to a recently fixated location compared to other locations. It has been proposed that this temporal O-IOR may have spatial consequences, facilitating foraging by inhibiting return to previously attended regions. In order to test this possibility, participants viewed arrays of objects and of words while their eye movements were recorded. Temporal O-IOR was observed, with equivalent effects for object and word arrays, indicating that temporal O-IOR is an oculomotor phenomenon independent of array content. There was no evidence for spatial inhibition of return. Instead, spatial facilitation of return was observed: Participants were significantly more likely than chance to make return saccades and to refixate just-visited locations. Further, the likelihood of making a return saccade to an object or word was contingent on the amount of time spent viewing that object or word before leaving it. This suggests that, unlike temporal O-IOR, return probability is influenced by cognitive processing. Taken together, these results are inconsistent with the hypothesis that inhibition of return functions as a foraging facilitator. The results also provide strong evidence for a different oculomotor bias that could serve as a foraging facilitator: saccadic momentum, a tendency to repeat the most recently executed saccade program. We suggest that models of visual attention could incorporate saccadic momentum in place of inhibition of return.

    Comet Odyssey is a proposed New Frontiers mission that would return the first samples from the surface of a cometary nucleus. Stardust demonstrated the tremendous power of analysis of returned samples in terrestrial laboratories versus what can be accomplished in situ with robotic missions. But Stardust collected only 1 milligram of coma dust, and the 6.1 km/s flyby speed heated samples up to 2000 K. Comet Odyssey would collect two independent 800 cc samples directly from the surface in a far more benign manner, preserving the primitive composition. Given a minimum surface density of 0.2 g/cm3, this would return two 160 g surface samples to Earth. Comet Odyssey employs solar-electric propulsion to rendezvous with the target comet. After 180 days of reconnaissance and site selection, the spacecraft performs a "touch-and-go” maneuver with surface contact lasting 3 seconds. A brush-wheel sampler on a remote arm collects up to 800 cc of sample. A duplicate second arm and sampler collects the second sample. The samples are placed in a return capsule and maintained at colder than -70 C during the return flight and at colder than -30 C during re-entry and for up to six hours after landing. The entire capsule is then refrigerated and transported to the Astromaterials Curatorial Facility at NASA/JSC for initial inspection and sample analysis by the Comet Odyssey team. Comet Odyssey's planned target was comet 9P/Tempel 1, with launch in December 2017 and comet arrival in June 2022. After a stay of 300 days at the comet, the spacecraft departs and arrives at Earth in May 2027. Comet Odyssey is a forerunner to a flagship Cryogenic Comet Sample Return mission that would return samples from deep below the nucleus surface, including volatile ices. This work was supported by internal funds from the Jet Propulsion Laboratory.

    Several studies have investigated neural correlates of aesthetic appreciation for paintings but to date the findings have been heterogeneous. This heterogeneity may be attributed to previous studies’ measurement of aesthetic appreciation of not only the beauty of paintings but also the beauty of motifs of the paintings. In order to better elucidate the beauty of paintings, it seems necessary to compare aesthetic appreciation of paintings and photographic analogs which included corresponding real images. We prepared for famous painters’ pictures and their photographic analogs which were set up to resemble each painting in order to investigate the hypothesis that there exist specific neural correlates associated with the aesthetic appreciation for paintings. Forty-four subjects participated in functional magnetic resonance study which required comparisons of aesthetic appreciation of paintings of still life and landscape versus photographic analogs including corresponding real images of still life and landscape. Bilateral cuneus and the left lingual gyrus were activated in the comparison of aesthetic appreciation of paintings versus photographic analogs. In conclusion, the present findings suggest a possibility of the existence of specific neural correlates associated with the aesthetic appreciation for paintings and that bilateral cuneus and the left lingual gyrus may be involved.

    1994-08-01

    Previous studies on the psychophysiology of human emotion have repeatedly shown general and occasionally specific facial EMG (mu v) and covert cardiovascular response relationships to emotionally provocative photographs. Less clear are the relationships between psychophysiological response indices measured during the silent reading of emotionally charged versus emotionally neutral text. In this study, 12 adult subjects were presented two emotionally loaded color and black-and-white photographs and two brief newspaper articles, one emotionally charged and the other emotionally neutral in content. Each independent stimulus was presented for 1 min., preceded by a rest according to a multiple baseline-reversal design. Subjects evaluated each pictorial and textual stimulus condition according to adjective dimensions on 7-point rating scales. Mean values for corrugator supercilii EMG (mu v), upper trapezius EMG (mu v), surface temperature (degrees F), and heart rate (bpm) measured by finger photoplethysmography were measured during each rest and test period. Significant increases in the subjects' mean corrugator supercilii EMG (mu v) measures were observed during all color and black-and-white photograph presentations for both emotional and neutral content. As predicted, the subjects' mean corrugator supercilii EMG (mu v) measures increased significantly while silently reading text with an obvious unpleasant emotional tone. A significant positive relationship was observed between the subjects' mean ratings and mean corrugator EMG (mu v) difference values for the emotionally loaded color photographs.

    2008-01-01

    This book is a companion to Byrnes's award-winning Lunar Orbiter Photographic Atlas of the Near Side of the Moon (Springer, 2005). It provides comprehensive coverage of the far side of the Moon, and is the first book that collects photographs from all five Lunar Orbiter missions: Clementine, Apollo, Luna, Zond, and Nozomi. As in the previous book, the scanning artifacts of the Lunar Orbiter photos have been cleaned. The photographs show each part of the far side in the most favorable resolution and sun angle. There are many high-altitude oblique photos that provide a feeling of being in space; this book is more like a photographic tour of the far side than an atlas.  The striking differences between the near and far side have been a major mystery for astronomers but this book suggests an explanation: a massive early impact on the near side produced the Near Side Megabasin; an impact so large that its rim is on the far side. The floor of this basin established the canvas for the portrait of the Man in the Moo...

    The identification of unknown human by smile photographs that show specific characteristics of each individual has found wide acceptance all over the world. Therefore this paper shows this situation reporting different cases which smile photograph analysis were crucial to determine the positive identification of unidentified human bodies. All the cases were subjected to personal identification by photographs of smile including one adult male found in an advanced stage of decomposition, one adult female disappeared during an ecotourism trip, and one carbonized body of a male individual found in a forest region. During the autopsy the photographs of the smile were used by comparison of the ante and postmortem images gave accurate and useful information not only about dental state but also the anatomical features surrounding the upper and lower anterior dental arches. This method is not time-consuming and also has the advantage of allowing extraoral dental examination. It is also recommended when there is a need to provide quantitative data for a forensic identification based on these structures.

    Full Text Available The effect of inflation to the stock return research had been held since three decades ago based on GeneralizeFisher’s Hypotheses, but ‘how inflation influenced stock return’ had become a debate until today. In Indonesiamost of the related research used inflation as one of the variables that influenced stock return despite of others inshort period of time. This research investigated the effect of inflation to the stock return in Indonesia within fifteenyears, which was divided into 3 (three periods of time reflecting different economic growth for each of it. Thepurpose of this allotment was to see the consistency how inflation influenced the stock market. Using a secondarydata from monthly inflation and IHSG period 1998 until 2012, included three hundred and sixty observation,simple regression model analyses was applied. This research acknowledged that inflation negatively influencedstock return in a long time period, but it did not exist in the short time period, except when the level of inflationreached 10%. In conclusion, inflation influence on the stock return was not ascertained by how long the investigationwas held but if there was any inflation rate reaching 10% within the period of investigation.

    can be derived from trees, by comparing the elevation return frequency from a number of individual Eucalypt trees in New South Wales, Australia, and comparing this to photography of the same trees. Airborne laser altimetry last significant return data was acquired in November 2006, which included ten Eucalypt trees. This was analysed using the assumption that probability of beam interception within a fixed height interval was proportional to vegetation area, and, assuming constant leaf thickness and angular distribution, vegetation mass. This provided a layered estimate for vegetation mass, relative within the tree. This was compared with analysis of photographs acquired in 2007 and 2010, indicating a change in structure and growth within the canopy over the intervening period for the younger, shorter trees. A potential problem with this form of analysis is the loss of information below the point at which all laser pulses have been intercepted, however in this case, no trees showed this, with at least 26% of pulses penetrating to ground level.

    Although photogrammetry is a widespread technique in the health field, despite of the methodological efforts distortions in the angular readings of the images are common. To measure the error of angular measurements in photo images with different digital resolutions in an object with pre-determined angles. We used a rubber ball with 52 cm in circumference. The object was previously marked with angles of 10°, 30°, 60° and 90° degrees. The photographic records were performed with the focal axis of the camera perpendicular and three meters away from the object, without the use of optical zoom and a resolution of 3, 5 and 10 Megapixels (Mp). All photographic records were stored and a previously trained experimenter using the computer program ImageJ analyzed the angular values of each photo. The measurements were performed twice within a fifteen-days interval. Subsequently, we calculated the accuracy, relative error and error in degrees values, precision and the Intraclass Correlation Coefficient (ICC). When analyzing the angle of 10°, the average accuracy of measurements was higher for those records of 3 Mp resolution compared to 5 and 10 Mp resolutions. The ICC was considered excellent for all resolutions. With regards to the analyzed angles in photographic records, it was possible to verify that the 90-degree angle photographs were more accurate, had lower relative error and error in degrees, and were more precise, regardless of image resolution. The photographs records that were taken with a 3 Mp resolution provided great accuracy and precision measurements and lower errors values, suggesting to be the proper resolution to generate image of angles of 10º and 30º.

  11. Single-image-based Modelling Architecture from a Historical Photograph

    Science.gov (United States)

    Dzwierzynska, Jolanta

    2017-10-01

    Historical photographs are proved to be very useful to provide a dimensional and geometrical analysis of buildings as well as to generate 3D reconstruction of the whole structure. The paper addresses the problem of single historical photograph analysis and modelling of an architectural object from it. Especially, it focuses on reconstruction of the original look of New-Town synagogue from the single historic photograph, when camera calibration is completely unknown. Due to the fact that the photograph faithfully followed the geometric rules of perspective, it was possible to develop and apply the method to obtain a correct 3D reconstruction of the building. The modelling process consisted of a series of familiar steps: feature extraction, determination of base elements of perspective, dimensional analyses and 3D reconstruction. Simple formulas were proposed in order to estimate location of characteristic points of the building in 3D Cartesian system of axes on the base of their location in 2D Cartesian system of axes. The reconstruction process proceeded well, although slight corrections were necessary. It was possible to reconstruct the shape of the building in general, and two of its facades in detail. The reconstruction of the other two facades requires some additional information or the additional picture. The success of the presented reconstruction method depends on the geometrical content of the photograph as well as quality of the picture, which ensures the legibility of building edges. The presented method of reconstruction is a combination of the descriptive method of reconstruction and computer aid; therefore, it seems to be universal. It can prove useful for single-image-based modelling architecture.

  12. DISTANCE MEASUREMENT BASED ON A SINGLE DEFOCUSED PHOTOGRAPH

    Directory of Open Access Journals (Sweden)

    N. A. Degotinsky

    2016-07-01

    Full Text Available Subject of Research. Westudied a method of estimating the object distance on the basis of its single defocused photograph. The method is based on the analysis of image defocus at the contour points corresponding to borders of photographed objects. It is supposed that the brightness drop in not defocused image of border can be simulated with an ideal step function – the Heaviside function. Method. The contours corresponding to local maxima of brightness gradient are detected in the initial image to be analyzed and recorded for further analysis. Then the initial image is subjected to additional defocusing by a Gaussian filter having the dispersion parameter of defined in advance value. The ratios of local gradient values for the initial and additionally defocused images are then calculated at the contour points, and the defocus values of initial image at the points of objects borders are estimated based on these ratios. A sparse map of relative remoteness is built on the basis of these estimations for the border points of photographed objects, and a dense depth map of relative distances is then calculated using a special interpolation technique. Main Results. The efficiency of described technique is illustrated with the results of distance estimation in the photographs of real environment. Practical Relevance. In contrast to the widely applied stereo-technique and distance measurement methods analyzing the sets of defocused images, the investigated approach enables dealing with a single photograph acquired in a standard way without setting any additional conditions and limitations. If the relative remoteness of objects may be estimated instead of their absolute distances, no special calibration is needed for the camera applied, and the pictures taken once previously in diversified situations can be analyzed using the considered technique.

    Criteria for return to sports and athletic activities after cervical spine surgery are unclear. There is limited literature regarding the outcomes and optimal criteria. Determining return to play criteria remains a challenge and continues to depend on the experience and good judgment of the treating surgeon. There is strong consensus in the literature, despite lack of evidence-based data, that athletes after single-level anterior cervical discectomy and fusion (ACDF) may safely return to collision and high-velocity sports. The athlete should be counseled and managed on a case-by-case basis, taking into consideration the type of sport, player-specific variables, and type of surgery performed. Published by Elsevier Inc.

We further prove that stock returns are best fit by the product distribution of the generalized inverse gamma and normal distributions. We find Brown noise in VIX and VXO time series and explain the mean and the variance of the relaxation times on approach to the steady-state distribution.

    We analyze, both analytically and numerically, the time-dependence of the return probability in closed systems of interacting particles. Main attention is paid to the interplay between two regimes, one of which is characterized by the Gaussian decay of the return probability, and another one is the well-known regime of the exponential decay. Our analytical estimates are confirmed by the numerical data obtained for two models with random interaction. In view of these results, we also briefly discuss the dynamical model which was recently proposed for the implementation of a quantum computation.

  2. Medical returns as class transformation: situating migrants' medical returns within a framework of transnationalism.

    Science.gov (United States)

    Horton, Sarah B

    2013-01-01

    Because studies of migrants' 'medical returns' have been largely confined to the field of public health, such forms of return migration are rarely contextualized within the rich social scientific literature on transnational migration. Drawing on ethnographic interviews with Mexican migrants in an immigrant enclave in central California, I show that migrants' reasons for returning to their hometowns for care must be understood within the class disjunctures facilitated by migration. While migrants' Medicaid insurance confined them to public clinics and hospitals in the United States, their migrant dollars enabled them to visit private doctors and clinics in Mexico. Yet medical returns were not mere medical arbitrage, but also allowed migrants to access care that had previously been foreclosed to them as poor peasants in Mexico. Thus crossing the border enabled a dual class transformation, as Mexican migrants transitioned from Medicaid recipients to cash-paying patients, and from poor rural peasants to 'returning royalty.'

    The purpose of this study was to compare the clinical outcomes, including the level of return to sport, of collision and non-collision athletes who had the Latarjet procedure. A total of 56 shoulders of 29 collision and 27 non-collision athletes were retrospectively analyzed. All study participants underwent the Latarjet procedure between 2007 and 2014. Median age at the time of surgery was 26.5 years(18-43) and follow-up duration was 67.0 months(24-113). At the final follow-up, 54 (96.4%) patients returned to sports. Nine patients (16.1%) returned to the same level of sports. In a group of collision athletes, 1 patient (3.4%) returned to the same level, 16 (55.2%) returned to lower level, 10 (34.5%) changed sports, and 2 (6.9%) quit sports. In a group of noncollision athletes, 8 (29.6%) returned to same level, 11 (40.7%) returned at a lower level and 8 (29.6%) changed sports. The level of return to sports in collision group was statistically different from that in noncollision group (p = 0.046). The mean VAS, Rowe and UCLA scores improved significantly in both groups (p < 0.001) with no statistically significant difference between both groups. Although the clinical outcomes were not significantly different between collision and non-collision athletes, the level of return to sports was significantly higher in the non-collision group than in the collision group. The result suggests that the level of physical demand according to sport type is an important prognostic factor which predicts the level of return to sport after the Lartarjet procedure in athletes.

    2005-01-01

    The aim of this study was to examine the photographic and radiographic success of the treatment of maxillary anterior primary incisors with composite resin strip crowns (SCs) placed in a private-practice setting after a minimum of 18 months. This was a retrospective, clinical study of patients who had SCs placed on primary maxillary incisors, returned for at least one 18-month recall examination, and whose parents consented to participate in the study. Radiographic and photographic examinations were used for evaluation. Two evaluators rated the images independently. One hundred forty-five restorations, placed in 52 children, were evaluated. The evaluations were performed after the crowns had been in place for an average of 31.3 months. None of the restorations were totally lost: 20% were rated as having lost some resin material, resulting in an 80% overall retention rate; 92% of the teeth demonstrated healthy pulps; 6% had some pulpal changes, but did not require immediate attention. Only 2 teeth showed radiographic evidence of pulpal pathology requiring treatment. SCs performed well for restoring primary incisors with large or multisurface caries for periods of over 3 years. This study suggests that SCs are likely to be successful and may be indicated as an excellent treatment choice for carious primary incisors with adequate tooth structure after caries removal, especially if esthetic concerns predominate.

    The Galahad asteroid sample return mission proposal to the NASA New Frontiers solicitation met all of the objectives for the Asteroid Rover/Sample Return mission as defined in that announcement. Galahad is in many ways similar to the Marco Polo and the OSIRIS-Rex proposals. All three missions plan bulk sample returns from primitive, C or B class Near Earth asteroids. Galahad in particular will rendezvous with and orbit the binary C-asteroid 1996 FG3, making extensive orbital measurements. It will then land and collect over 60 g of well-documented samples with geologic context for return to Earth. The samples are expected to provide abundant materials from the early solar system, including chondrules and CAIs, as well as a primitive assemblage of organics, presolar grains and probably hydrated minerals. Analyses of these samples will yield new understanding of the early solar system, planetary accretion, and the nature and origins of prebiotic organic material. We will discuss scientific and technical approaches to characterization of, landing on, and sample collection from small primitive bodies.

  11. Multivariate models of adult Pacific salmon returns.

    Directory of Open Access Journals (Sweden)

    Brian J Burke

    Full Text Available Most modeling and statistical approaches encourage simplicity, yet ecological processes are often complex, as they are influenced by numerous dynamic environmental and biological factors. Pacific salmon abundance has been highly variable over the last few decades and most forecasting models have proven inadequate, primarily because of a lack of understanding of the processes affecting variability in survival. Better methods and data for predicting the abundance of returning adults are therefore required to effectively manage the species. We combined 31 distinct indicators of the marine environment collected over an 11-year period into a multivariate analysis to summarize and predict adult spring Chinook salmon returns to the Columbia River in 2012. In addition to forecasts, this tool quantifies the strength of the relationship between various ecological indicators and salmon returns, allowing interpretation of ecosystem processes. The relative importance of indicators varied, but a few trends emerged. Adult returns of spring Chinook salmon were best described using indicators of bottom-up ecological processes such as composition and abundance of zooplankton and fish prey as well as measures of individual fish, such as growth and condition. Local indicators of temperature or coastal upwelling did not contribute as much as large-scale indicators of temperature variability, matching the spatial scale over which salmon spend the majority of their ocean residence. Results suggest that effective management of Pacific salmon requires multiple types of data and that no single indicator can represent the complex early-ocean ecology of salmon.

    Most modeling and statistical approaches encourage simplicity, yet ecological processes are often complex, as they are influenced by numerous dynamic environmental and biological factors. Pacific salmon abundance has been highly variable over the last few decades and most forecasting models have proven inadequate, primarily because of a lack of understanding of the processes affecting variability in survival. Better methods and data for predicting the abundance of returning adults are therefore required to effectively manage the species. We combined 31 distinct indicators of the marine environment collected over an 11-year period into a multivariate analysis to summarize and predict adult spring Chinook salmon returns to the Columbia River in 2012.

    Jesick, Mark

    2017-09-01

    Mars double-flyby free-return trajectories that pass twice through the Martian atmosphere are documented. This class of trajectories is advantageous for potential Mars atmospheric sample return missions because of its low geocentric energy at departure and arrival, because it would enable two sample collections at unique locations during different Martian seasons, and because of its lack of deterministic maneuvers. Free return opportunities are documented over Earth departure dates ranging from 2015 through 2100, with viable missions available every Earth-Mars synodic period. After constraining the maximum lift-to-drag ratio to be less than one, the minimum observed Earth departure hyperbolic excess speed is 3.23 km/s, the minimum Earth atmospheric entry speed is 11.42 km/s, and the minimum round-trip flight time is 805 days. An algorithm using simplified dynamics is developed along with a method to derive an initial estimate for trajectories in a more realistic dynamic model. Multiple examples are presented, including free returns that pass outside and inside of Mars's appreciable atmosphere.

  20. Return Migration to Mexico: Does Health Matter?

    Arenas, Erika; Goldman, Noreen; Pebley, Anne R; Teruel, Graciela

    2015-12-01

    We use data from three rounds of the Mexican Family Life Survey to examine whether migrants in the United States returning to Mexico in the period 2005-2012 have worse health than those remaining in the United States. Despite extensive interest by demographers in health-related selection, this has been a neglected area of study in the literature on U.S.-Mexico migration, and the few results to date have been contradictory and inconclusive. Using five self-reported health variables collected while migrants resided in the United States and subsequent migration history, we find direct evidence of higher probabilities of return migration for Mexican migrants in poor health as well as lower probabilities of return for migrants with improving health. These findings are robust to the inclusion of potential confounders reflecting the migrants' demographic characteristics, economic situation, family ties, and origin and destination characteristics. We anticipate that in the coming decade, health may become an even more salient issue in migrants' decisions about returning to Mexico, given the recent expansion in access to health insurance in Mexico.

    In humanitarian emergencies, such as the current deceased migrants in the Mediterranean, antemortem documentation needed for identification may be limited. The use of visual identification has been previously reported in cases of mass disasters such as Thai tsunami. This pilot study explores the ability of observers to match unfamiliar faces of living and dead persons and whether facial morphology can be used for identification. A questionnaire was given to 41 students and five professionals in the field of forensic identification with the task to choose whether a facial photograph corresponds to one of the five photographs in a lineup and to identify the most useful features used for recognition. Although the overall recognition score did not significantly differ between professionals and students, the median scores of 78.1% and 80.0%, respectively, were too low to consider this method as a reliable identification method and thus needs to be supported by other means. © 2017 American Academy of Forensic Sciences.

    Full Text Available Objectives: To evaluate and compare the differences between the spontaneous smile captured by conventional photography and the video clip method. Methods: A digital video camera was used to capture smiles in 100 subjects using the static and videographic methods. Results: Measurements of the anterior and posterior height of the smile, interlabial gap, lower incisal display and eye wink on photographs obtained by the two methods showed considerable differences. Except for the anterior and posterior height of the smile in girls, these differences were statistically significant (P < 0.005. The majority of subjects showed parallel smile arcs back to the maxillary second premolar though differences existed between the two methods. Conclusions: In orthodontic treatment planning, certain treatment modalities (in particular intrusion and expansion are based on an analysis of the full spontaneous smile. Since the videographic method is better able to capture this smile, it may be a preferred method of obtaining pretreatment facial photographs.

    2017-09-01

    Illumination decomposition for a single photograph is an important and challenging problem in image editing operation. In this paper, we present a novel coarse-to-fine strategy to perform illumination decomposition for photograph with multiple light sources. We first reconstruct the lighting environment of the image using the estimated geometry structure of the scene. With the position of lights, we detect the shadow regions as well as the highlights in the projected image for each light. Then, using the illumination cues from shadows, we estimate the coarse illumination decomposed image emitted by each light source. Finally, we present a light-aware illumination optimization model, which efficiently produces the finer illumination decomposition results, as well as recover the texture detail under the shadow. We validate our approach on a number of examples, and our method effectively decomposes the input image into multiple components corresponding to different light sources.

    2017-09-01

    Photographic fisheye lenses with fixed focal length for cameras with different sensor formats have been well developed for decades. However, photographic fisheye lenses with variable focal length are rare on the market due in part to the greater design difficulty. This paper presents a large aperture zoom fisheye lens for DSLR cameras that produces both circular and diagonal fisheye imaging for 35-mm sensors and diagonal fisheye imaging for APS-C sensors. The history and optical characteristics of fisheye lenses are briefly reviewed. Then, a 9.2- to 16.1-mm F/2.8 to F/3.5 zoom fisheye lens design is presented, including the design approach and aberration control. Image quality and tolerance performance analysis for this lens are also presented.

    To construct an easy-to-use server-based database that stores photographs of patients undergoing reconstructive surgery for cutaneous facial defects and organizes them in a manner best suited for rapid search and education. An institutional review board-approved user-modifiable database was designed using OnBase software (Hyland Software Inc., Westlake, OH) to store both the photographs of patients undergoing reconstructive surgery and the pertinent clinical data. We designed a database using the OnBase software system (Hyland Software Inc.) to catalog patient data and photographs (pre-, intra-, and postoperative) and allow searches based on key data points. The database operates on three different frames: an upload frame, retrieval frame, and patient document frame. Data entry was based on patients undergoing facial reconstruction of Mohs defects, and upload is in the form of 25 keywords for which data values are entered via dropdown menus. Keyword entry describes defect description, flap nomenclature, flap design, outcomes, and complications. The database allows easy and rapid searches of case examples based on a number of criteria. It allows the user to view multiple examples of different patients with a given defect as defined by location, depth, and size. Server-based database systems such as OnBase (Hyland Software Inc.) provide platforms that can be used to create user-friendly photograph and data collection systems. Our database provides a way to educate medical students and surgeons-in-training, review personal outcomes, and exercise continued practice-based learning. Implementation of similar databases could potentially be utilized around the globe to facilitate education and self-assessment because OnBase (Hyland Software Inc.) and other similar software platforms are widely available within healthcare systems.

    High speed photography in conjunction with electron microscopy and a pressure measuring technique have been used to investigate the differences between dead-pressed and non-dead-pressed samples of the primary explosive Mercury Fulminate (Hg Ful). Photographs of reaction propagation were taken in transmitted light using a specially adapted drop-weight machine with transparent anvils. The results of these experiments suggested a mechanism for dead-pressing in Hg Ful based on the microscopic internal structure of the compacted explosive.

    Several scar-scoring scales exist to clinically monitor burn scar development and maturation. Although scoring scars through direct clinical examination is ideal, scars must sometimes be scored from photographs. No scar scale currently exists for the latter purpose. We modified a previously described scar scale (Yeong et al., J Burn Care Rehabil 1997) and tested the reliability of this new scale in assessing burn scars from photographs. The new scale consisted of three parameters as follows: scar height, surface appearance, and color mismatch. Each parameter was assigned a score of 1 (best) to 4 (worst), generating a total score of 3-12. Five physicians with burns training scored 120 representative photographs using the original and modified scales. Reliability was analyzed using coefficient of agreement, Cronbach alpha, intraclass correlation coefficient, variance, and coefficient of variance. Analysis of variance was performed using the Kruskal-Wallis test. Color mismatch and scar height scores were validated by analyzing actual height and color differences. The intraclass correlation coefficient, the coefficient of agreement, and Cronbach alpha were higher for the modified scale than those of the original scale. The original scale produced more variance than that in the modified scale. Subanalysis demonstrated that, for all categories, the modified scale had greater correlation and reliability than the original scale. The correlation between color mismatch scores and actual color differences was 0.84 and between scar height scores and actual height was 0.81. The modified scar scale is a simple, reliable, and useful scale for evaluating photographs of burn patients. Copyright © 2015 Elsevier Inc. All rights reserved.

  13. Photographic and CCD Sky Patrols with Small Telescopes

    Science.gov (United States)

    Kroll, Peter

    Since the twenties of the last century Sonneberg Observatory runs in each clear night a photographic Sky Patrol with a system of small telescopes (55/250 mm) reaching 14m in the blue and 13m in the yellow-red. In addition, a so-called Field Patrol is run with 2 astrographs (400/2000 mm) and a Schmidt camera (500/700/1720 mm) covering 80 selected fields along or near the Milky Way. From these instruments an archive of alomost 300,000 photographic plates arose, documenting the history of the starry night over more than 75 years. Currently much effort is made to take over this photographic sky patrol by a system of electronic detectors. Owing to the fact, that wide-field systems need either large CCDs or arrays of CCDs in order to cover the whole field of view, the technical availability of large detectors was one of the central problems in past. We now invent the use of a PHILIPS 4K×7K chip in wide-field astronomy for Whole-Sky Patrol. Although the chip has a quantum efficiency of only about 30 %, its big size (12μm pixel size) of 48×84 mm offers, for the first time, the replacement of large photographic plates by a single CCD chip. We report our first experiences with this chip when using it with a super wide-angle objective for whole-sky imaging each minute down to ca. 10m for investigating different targets (variable stars, meteors, GRB counterparts, etc.) and first trial to use the large-size chip with other small telescopes (400 to 600 mm diameter) at Sonneberg Observatory.

Venezuela does not have a tool like this, properly validated and published. The aim of the study was develop a photographic atlas as a complementary tool for assess usual food consumption in Venezuelan adults.Material and Methods: Foods were classified into 13 groups according to their similarity in nutrient content according to the table of composition and the food balance sheet of Venezuela. We selected the most consumed by Venezuelans according to data from national studies and another researches by the authors. For each food were set 3 portion sizes: small, medium and large; which were weighed in an electronic balance before taking a picture. Later, the atlas underwent a valuation process by experts.Results: The instrument includes 110 foods with a total of 300 photographs, distributed in 100 sheets, presenting the advantages of quality control used during the planning and design, the review of national and international reference materials. The experts successfully assessed the pertinence of the items and the relevance of the atlas information.Conclusions: The photographic atlas of foods developed, in the opinion of the expert reviewers, could be a useful tool to be used in the evaluation of food consumption in Venezuelan adults. However, to fulfill this purpose, the proposed instrument should be validated to prove their technical conditions of validity and reliability.

  17. On the detection of cracks in photographic prints

    Science.gov (United States)

    Restrepo, Alfredo; Fogar, Erika; Ramponi, Giovanni

    2008-02-01

    A method for the detection of cracks in old paper photographs is presented. Cracks in photographic prints usually result from a folding of the paper support of the photograph; they often extend across the entire image, along a preferred orientation. A first clue we exploit for crack detection is the fact that old prints have a characteristic sepia hue, due to aging and to the type of processing used at the time; a break of the gelatin exposes the white support paper; likewise, a break of the paper causes a black region in the digitized image. Thus, cracks are usually achromatic; this fact can be used for their detection on a color space with an explicit hue component. A series of parallel microcracks that run along the direction of a main crack usually result as well; even though the gelatin may not be broken, the folds corresponding to these microcracks cause a set of image discontinuities, observable at a high-enough resolution. In an interactive process, the user indicates the ends of the crack on the frame of the photo and the algorithm detects the crack pixels. In addition to color, the algorithm uses a multidirectional, multiresolution Gabor approach and mathematical morphology. The resulting method provides crack detection with good performance, as evidenced by the corresponding Receiver Operating Characteristics (ROC) graphs.1

    This paper addresses the technical aspects of the sample return system for the upcoming Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) asteroid sample return mission. The overall mission design and current implementation are presented as an overview to establish a context for the technical description of the reentry and landing segment of the mission.The prime objective of the OSIRIS-REx mission is to sample a primitive, carbonaceous asteroid and to return that sample to Earth in pristine condition for detailed laboratory analysis. Targeting the near-Earth asteroid Bennu, the mission launches in September 2016 with an Earth reentry date of September 24, 2023.OSIRIS-REx will thoroughly characterize asteroid Bennu providing knowledge of the nature of near-Earth asteroids that is fundamental to understanding planet formation and the origin of life. The return to Earth of pristine samples with known geologic context will enable precise analyses that cannot be duplicated by spacecraft-based instruments, revolutionizing our understanding of the early Solar System. Bennu is both the most accessible carbonaceous asteroid and one of the most potentially Earth-hazardous asteroids known. Study of Bennu addresses multiple NASA objectives to understand the origin of the Solar System and the origin of life and will provide a greater understanding of both the hazards and resources in near-Earth space, serving as a precursor to future human missions to asteroids.This paper focuses on the technical aspects of the Sample Return Capsule (SRC) design and concept of operations, including trajectory design and reentry retrieval. Highlights of the mission are included below.The OSIRIS-REx spacecraft provides the essential functions for an asteroid characterization and sample return mission: attitude control propulsion power thermal control telecommunications command and data handling structural support to ensure successful

    2014-09-01

    Full Text Available Background:  The aim of this exploratory empirical research was to evaluate the level of cooperation in the area of reverse logistics between selected retail chains and logistics operators and suppliers; to identify and evaluate the influence the procedures of handling returns have on the relationships with customers, cost reduction, value recovery, inventory reduction and increasing profitability; as well as determining to what extent logistics operators are involved in the procedures of handling returns in the analysed chains. Methods: Based on the literature and the experience of researchers from developed countries a questionnaire was constructed which was subsequently used to conduct empirical research in selected retail chains operating in two provinces in Poland. The questionnaire survey involved the sales personnel of selected retail chains in the clothing industry. Overall, 105 questionnaires were collected and analysed. Results: Various aspects of cooperation with suppliers and logistics operators in respect of handling returns were evaluated. Most indicators of cooperation were evaluated favourably, with the exception of joint access to the database, the use of inventory data available online, and access to information from the warehouse, which received low marks from the respondents. In the case of the studied stores, some of the activities in the area of reverse logistics are outsourced; for example, obtaining products from users, logistics, and the transport of returns are typically done by an outside operator. Inspection, sorting, appraisal, repairs, as well as the sales of refurbished products are usually performed within the studied retail corporations. Conclusions: The research has shown that the retail chains developed very good programmes for handling returns in the supply chain, as evidenced by the presented and highly rated indicators of cooperation, with the exception of information exchange where there is still much

    2011-12-01

    OSIRIS-REx is an asteroid sample return mission to organic-rich asteroid (101955) 1999 RQ36. The mission seeks to address deep questions: where did we come from; what is our destiny? Earth sterilized itself during its formation, yet here we are today. Where did the organics come from? To do so, we will return at least 60g of pristine, uncontaminated, organic-rich regolith for study on Earth by advanced analytical equipment. Because it is relatively easy for us to get the RQ36, it is relatively easy for it to get to us, making I the most potentially hazardous asteroid know to humanity with a 1:1800 probability of impacting the Earth in 2180. We will study the Yarkovsky effect, thermal forces that cause small objects to deviate from keplerian orbits, with the goal of understanding how to mitigate against a civilization-ending or species-ending impact catastrophe. The mission launches in September, 2016, arrives at RQ36 in November of 2019, and spends about a year conducting detailed studies of RQ36 in order to select the best sampling site. Sampling is achieved by approaching the surface ay 10 cm/sec and agitating the regolith with nitrogen gas on contact. The agitated regolith is collected in a sample head, which is stowed in the Sample return capsule for return to Earth at the UTTR Test range in Utah in September 2023. Two years of funded studies are carried out by the U.S. and world community before end of mission in 2025, after which samples will still be available through the NASA-JSC Curation Facility. OSIRIS-REx will return samples never before available for study on Earth, probably using some instruments yet to be invented. In addition, OSIRIS-REx will provide "ground truth" for telescope observations of airless bodies by returning a pristine sample of the surface of RQ36. OSIRIS-REx will evaluate resources available to future human missions, both materials and technologies such as proximity operations. And we will learn how to mitigate against impact

    KIC 8462852 is an F3V star which decreased 20% in visual brightness twice from 5 to 20 days (Boyajian et al., 2016, MNRAS, 457, 3988) in 2011 and again in 2013. New observations show decreases of a few percent in May 2017 (Waagen 2017, AAVSO Alert Notice, 579), and reanalysis of Kepler data shows a variation of 928.25 days and 22 dimming events (Kiefer et al. 2017, accepted). Photometry from the All-Sky Automated Survey for Supernovae and the All-Sky Automated Survey (ASAS) indicate two brightening episodes and a steady decrease in magnitude of 6.3 +/- 1.4 mmag/yr (Simon et al 2017, accepted). Photometric studies from photographic plate collections include a light curve from 1338 Harvard College Observatory plates over the period 1890 to 1989 (Schaefer 2016, ApJ, 822, L34) that indicates KIC 8462852 is dimming 0.164 +/- 0.013 magnitudes per century.

(2016, ApJ, 825, 73) present B and V light curves from photometry from the Sonneberg Observatory photographic plate collection (Brauer and Fuhrmann 1992, Die Sterne, 68, 19) covering the period from 1934 to 1995. The light curve suggests less than 3% or 0.03 magnitude per century decrease in brightness, consistent with the ASAS light curve and Kepler data.Another consistent set of astronomical photographic plates with KIC 8462852 are in the Maria Mitchell Observatory (MMO) collection (Strelnitski 2009 in ASP Conference Series Vol. 410 p. 96). This collection is located in the Astronomical Photographic Data Archive at the Pisgah Astronomical Research Institute. We extracted the photographic magnitudes of KIC 8462852 from 743 plates from 1930 to 1988. We chose 8 nearby comparison stars within one spectral subclass and within 0.05 magnitudes of KIC 8462852, and not identified as variables. The photometry is calibrated to the USNO B filter, closest in bandpass to the emulsion wavelength sensitivity. The light curve of KIC 8462852 suggests a trend of about 0.1 +/- 0.07 magnitudes per century decrease, an

    The availability of massive digital traces of human whereabouts has offered a series of novel insights on the quantitative patterns characterizing human mobility. In particular, numerous recent studies have lead to an unexpected consensus: the considerable variability in the characteristic travelled distance of individuals coexists with a high degree of predictability of their future locations. Here we shed light on this surprising coexistence by systematically investigating the impact of recurrent mobility on the characteristic distance travelled by individuals. Using both mobile phone and GPS data, we discover the existence of two distinct classes of individuals: returners and explorers. As existing models of human mobility cannot explain the existence of these two classes, we develop more realistic models able to capture the empirical findings. Finally, we show that returners and explorers play a distinct quantifiable role in spreading phenomena and that a correlation exists between their mobility patterns and social interactions.

    Full Text Available Homogeneity of die castings is influenced by wide range of technological parameters as piston velocity in filling chamber of die casting machine, filling time of mould cavity, temperature of cast alloy, temperature of the mould, temperature of filling chamber, surface pressure on alloy during mould filling, final pressure and others. Based on stated parameters it is clear, that main parameters of die casting are filling time of die mould cavity and velocity of the melt in the ingates. Filling time must ensure the complete filling of the mould cavity before solidification process can negatively influence it. Among technological parameters also belong the returning material, which ratio in charge must be constrained according to requirement on final homogeneity of die castings. With the ratio of returning material influenced are the mechanical properties of castings, inner homogeneity and chemical composition.

  12. Mars Sample Return Using Solar Sail Propulsion

    Science.gov (United States)

    Johnson, Les; Macdonald, Malcolm; Mcinnes, Colin; Percy, Tom

    2012-01-01

    Many Mars Sample Return (MSR) architecture studies have been conducted over the years. A key element of them is the Earth Return Stage (ERS) whose objective is to obtain the sample from the Mars Ascent Vehicle (MAV) and return it safely to the surface of the Earth. ERS designs predominantly use chemical propulsion [1], incurring a significant launch mass penalty due to the low specific impulse of such systems coupled with the launch mass sensitivity to returned mass. It is proposed to use solar sail propulsion for the ERS, providing a high (effective) specific impulse propulsion system in the final stage of the multi-stage system. By doing so to the launch mass of the orbiter mission can be significantly reduced and hence potentially decreasing mission cost. Further, solar sailing offers a unique set of non-Keplerian low thrust trajectories that may enable modifications to the current approach to designing the Earth Entry Vehicle by potentially reducing the Earth arrival velocity. This modification will further decrease the mass of the orbiter system. Solar sail propulsion uses sunlight to propel vehicles through space by reflecting solar photons from a large, mirror-like surface made of a lightweight, reflective material. The continuous photonic pressure provides propellantless thrust to conduct orbital maneuvering and plane changes more efficiently than conventional chemical propulsion. Because the Sun supplies the necessary propulsive energy, solar sails require no onboard propellant, thus reducing system mass. This technology is currently at TRL 7/8 as demonstrated by the 2010 flight of the Japanese Aerospace Exploration Agency, JAXA, IKAROS mission. [2

  16. Return to play after infectious mononucleosis.

    Science.gov (United States)

    Becker, Jonathan A; Smith, Julie Anne

    2014-05-01

    Infectious mononucleosis is a disease primarily of adolescence and early adulthood. The risk of splenic injury and chronic fatigue make return-to-play decisions a challenge for the clinician caring for athletes with infectious mononucleosis. Data were obtained from the PubMed and MEDLINE databases through December 2012 by searching for epidemiology, diagnosis, clinical manifestations, management, and the role of the spleen in infectious mononucleosis. Clinical review. Level 4. Infectious mononucleosis is commonly encountered in young athletes. Its disease pattern is variable and can affect multiple organ systems. Supportive care is the cornerstone, with little role for medications such as corticosteroids. Physical examination is unreliable for the spleen, and ultrasound imaging has limitations in its ability to guide return-to-play decisions. Exercise does not appear to place the young athlete at risk for chronic fatigue, but determining who is at risk for persistent symptoms is a challenge. Return-to-play decisions for the athlete with infectious mononucleosis need to be individualized because of the variable disease course and lack of evidence-based guidelines.

  17. Earnings Quality Measures and Excess Returns.

    Science.gov (United States)

    Perotti, Pietro; Wagenhofer, Alfred

    2014-06-01

    This paper examines how commonly used earnings quality measures fulfill a key objective of financial reporting, i.e., improving decision usefulness for investors. We propose a stock-price-based measure for assessing the quality of earnings quality measures. We predict that firms with higher earnings quality will be less mispriced than other firms. Mispricing is measured by the difference of the mean absolute excess returns of portfolios formed on high and low values of a measure. We examine persistence, predictability, two measures of smoothness, abnormal accruals, accruals quality, earnings response coefficient and value relevance. For a large sample of US non-financial firms over the period 1988-2007, we show that all measures except for smoothness are negatively associated with absolute excess returns, suggesting that smoothness is generally a favorable attribute of earnings. Accruals measures generate the largest spread in absolute excess returns, followed by smoothness and market-based measures. These results lend support to the widespread use of accruals measures as overall measures of earnings quality in the literature.

  18. Allan deviation analysis of financial return series

    Hernández-Pérez, R.

    2012-05-01

    We perform a scaling analysis for the return series of different financial assets applying the Allan deviation (ADEV), which is used in the time and frequency metrology to characterize quantitatively the stability of frequency standards since it has demonstrated to be a robust quantity to analyze fluctuations of non-stationary time series for different observation intervals. The data used are opening price daily series for assets from different markets during a time span of around ten years. We found that the ADEV results for the return series at short scales resemble those expected for an uncorrelated series, consistent with the efficient market hypothesis. On the other hand, the ADEV results for absolute return series for short scales (first one or two decades) decrease following approximately a scaling relation up to a point that is different for almost each asset, after which the ADEV deviates from scaling, which suggests that the presence of clustering, long-range dependence and non-stationarity signatures in the series drive the results for large observation intervals.

  19. Malaria in a returning traveler from Jamaica.

    Kavanaugh, Michael; Bavaro, Mary

    2014-06-01

    Malaria in Jamaica is a real, but uncommon entity and poses a health risk to our Department of Defense personnel, which should not be overlooked in returning travelers. Malaria in Jamaica was actually considered eradicated in the 1960s, but there has been a reemergence attributed to the combination of Haitian nationals as well as endemic Anopheles mosquitoes in the Kingston area. Our facility recently admitted a 33-year-old Marine who had two Emergency Department visits before being evaluated for malaria. He had returned from Kingston 14 days before presentation, which included fever, night sweats, and headache followed by a period of malaise prior to the next paroxysm. He was found to have a 1.5% parasitemia with Malaria falciparum that borders on severe malaria. Fortunately, he was treated effectively with atovaquone/proguanil and had a favorable outcome. The Center for Disease Control acknowledges that malaria is present in Jamaica, but only recommends mosquito avoidance without prophylaxis. This case emphasizes the need to consider malaria in differential diagnosis in Jamaica as well as in any returning travelers with fever because of broad global travel.

    2017-06-01

    Many experiments have found that participants take more investment risk if they see returns less frequently, see portfolio-level returns (rather than each individual asset's returns), or see long-horizon (rather than one-year) historical return distributions. In contrast, we find that such information aggregation treatments do not affect total equity investment when we make the investment environment more realistic than in prior experiments. Previously documented aggregation effects are not robust to changes in the risky asset's return distribution or the introduction of a multi-day delay between portfolio choice and return realizations.

    2015-12-01

    Blood pressure (BP) elevation in medical office settings in patients who are normotensive in nonmedical settings is an effect known as 'white coat hypertension'. This phenomenon is thought to be due to situational anxiety caused by the experience of visiting a doctor and the anxiety-inducing nature of the medical office. Our study was designed to determine if carefully selected photographic art could counter the anxiety that causes white coat hypertension and lead to lower BP recordings in some patients. 117 adults, non-pregnant patients from the Louisiana State University Health Sciences Center Family Medicine Resident Clinic participated in this study. After the triage nurse measured the BP, the patients were randomly placed in either an exam room with standard medical posters (control room) or in an exam room with photographic art (photo room). The BP was measured in the exam room. After the medical visit, the patients switched rooms and the BP was measured a third time. The patients were asked to fill out a questionnaire to identify room preference. On average, the BP obtained in the control rooms was higher than that obtained in the photo rooms. There was a statistically significant difference between the mean arterial pressure, systolic BP and diastolic BP between the control room and the photo room. Landscape photographic art may have the beneficial effect of reducing BP in medical office examination rooms. Published by the BMJ Publishing Group Limited.

  5. Digital Photograph Security: What Plastic Surgeons Need to Know.

    Thomas, Virginia A; Rugeley, Patricia B; Lau, Frank H

    2015-11-01

    Sharing and storing digital patient photographs occur daily in plastic surgery. Two major risks associated with the practice, data theft and Health Insurance Portability and Accountability Act (HIPAA) violations, have been dramatically amplified by high-speed data connections and digital camera ubiquity. The authors review what plastic surgeons need to know to mitigate those risks and provide recommendations for implementing an ideal, HIPAA-compliant solution for plastic surgeons' digital photography needs: smartphones and cloud storage. Through informal discussions with plastic surgeons, the authors identified the most common photograph sharing and storage methods. For each method, a literature search was performed to identify the risks of data theft and HIPAA violations. HIPAA violation risks were confirmed by the second author (P.B.R.), a compliance liaison and privacy officer. A comprehensive review of HIPAA-compliant cloud storage services was performed. When possible, informal interviews with cloud storage services representatives were conducted. The most common sharing and storage methods are not HIPAA compliant, and several are prone to data theft. The authors' review of cloud storage services identified six HIPAA-compliant vendors that have strong to excellent security protocols and policies. These options are reasonably priced. Digital photography and technological advances offer major benefits to plastic surgeons but are not without risks. A proper understanding of data security and HIPAA regulations needs to be applied to these technologies to safely capture their benefits. Cloud storage services offer efficient photograph sharing and storage with layers of security to ensure HIPAA compliance and mitigate data theft risk.

    Forests are widely monitored using a variety of remote sensing data and techniques. Remote sensing offers benefits compared to traditional in-situ forest inventories made by experts. One of the main benefits is that the number of ground reference plots can be significantly reduced. Remote sensing of forests can provide reduced costs and time requirement compared to full forest inventories. The availability of ground reference data has been a bottleneck in remote sensing analysis over wide forested areas, as the acquisition of this data is an expensive and slow process. In this paper we present a tool for estimating forest inventory data from geo-located photographs. The tool can be used to estimate in-situ forest inventory data including estimated biomass, tree species, tree height and diameter. The collected in-situ forest measurements can be utilized as a ground reference material for spaceborne or airborne remote sensing data analysis. The GPS based location information with measured forest data makes it possible to introduce measurements easily as in-situ reference data. The central projection geometry of digital photographs allows the use of the relascope principle [1] to measure the basal area of stems per area unit, a variable very closely associated with tree biomass. Relascope is applied all over the world for forest inventory. Experiments with independent ground reference data have shown that in-situ data analysed from photographs can be utilised as reference data for satellite image analysis. The concept was validated by comparing mobile measurements with 54 independent ground reference plots from the Hyytiälä forest research station in Finland [2]. Citizen scientists could provide the manpower for analysing photographs from forests on a global level and support researchers working on tasks related to forests. This low-cost solution can also increase the coverage of forest management plans, particularly in regions where possibilities to invest on

    To investigate inactive nurses' human capital, intention to return to hospital nursing and incentives for returning. Few studies have discussed the loss of human capital with regard to inactive nurses and how to attract them to return to clinical work. Systematic random sampling was used, with 328 subjects completing the mailed questionnaires, resulting in a response rate of 25.4%. Inactive nurses not only had moderate to high human capital (average years of nursing experience was 10.29, with moderate to high levels of nursing professional commitment and nursing competence) and were young. Forty-three percent of subjects reported intending to return to hospital nursing. Sufficient nurse staffing, greater safety in the working environment, and re-entry preparation programmes were incentives for returning. Recruiting inactive nurses back to hospital work is vital and feasible as inactive nurses had a moderate to high degree of human capital. The most feasible way is offering reasonable working conditions, in particular, providing sufficient staffing, a safe working environment and re-entry preparation programmes. The findings confirm the human capital of inactive nurses and provide concrete directions for nursing managers to follow when recruiting inactive nurses to hospital nursing. © 2015 John Wiley & Sons Ltd.

    A questionnaire survey was mailed to members of the Cervical Spine Research Society, the Herodiuus Sports Medicine Society, and to members of the authors' Department of Orthopaedics. The purpose of our study was to evaluate what influence, if any, factors such as published guidelines, type of sport of the patient, number of years in practice, subspecialty interest, and sports participation of the respondent held in the "return to play" decision-making process after a cervical spine injury. The consequences of cervical spine injury are potentially catastrophic, and return to play decisions in athletes with a history of neck injury can be agonizing. Although recent publications have addressed some of the concerns regarding cervical spine injuries in the athletic population, many questions remain unanswered. Factors such as published guidelines, type of sport of the patient, number of years in practice, subspecialty interest, and sports participation of the respondent have all been suggested as having a possible role in return to play decisions. Representative radiographs and case histories of 10 athletes who had sustained neck injury were mailed to 346 physicians. For each case physicians selected every type of play (of six categories) that they felt comfortable recommending. Type of play was divided into six categories: Type 1, collision sports; Type 2, contact sports; Type 3, noncontact, high velocity sports; Type 4, noncontact, repetitive load sports (e.g., running); Type 5, noncontact, low impact sports; Type 6, no sports. In addition, demographic data regarding board certification, subspecialty interest, number of years in practice, use of guidelines in return to play decisions, and personal participation in sports were queried from all respondents. Statistical analysis was completed with Statview (Berkeley, CA). Basic descriptive statistics, chi2, and ANOVA were used where appropriate.

    A Mars Sample Return (MSR) mission is the highest priority science mission for the next decade as recommended by the recent Decadal Survey of Planetary Science. However, an affordable program to carry this out has not been defined. This paper describes a study that examined use of emerging commercial capabilities to land the sample return elements, with the goal of reducing mission cost. A team at NASA Ames examined the feasibility of the following scenario for MSR: A Falcon Heavy launcher injects a SpaceX Dragon crew capsule and trunk onto a Trans Mars Injection trajectory. The capsule is modified to carry all the hardware needed to return samples collected on Mars including a Mars Ascent Vehicle (MAV), an Earth Return Vehicle (ERV) and Sample Collection and Storage hardware. The Dragon descends to land on the surface of Mars using SuperSonic Retro Propulsion (SSRP) as described by Braun and Manning [IEEEAC paper 0076, 2005]. Samples are acquired and deliverd to the MAV by a prelanded asset, possibly the proposed 2020 rover. After samples are obtained and stored in the ERV, the MAV launches the sample-containing ERV from the surface of Mars. We examined cases where the ERV is delivered to either low Mars orbit (LMO), C3 = 0 (Mars escape), or an intermediate energy state. The ERV then provides the rest of the energy (delta V) required to perform trans-Earth injection (TEI), cruise, and insertion into a Moon-trailing Earth Orbit (MTEO). A later mission, possibly a crewed Dragon launched by a Falcon Heavy (not part of the current study) retrieves the sample container, packages the sample, and performs a controlled Earth re-entry to prevent Mars materials from accidentally contaminating Earth. The key analysis methods used in the study employed a set of parametric mass estimating relationships (MERs) and standard aerospace analysis software codes modified for the MAV class of launch vehicle to determine the range of performance parameters that produced converged

    Martian rock and soil, collected by robotic spacecraft, will be returned to terrestrial laboratories early in the next century. Current plans call for the samples to be immediately placed into biological containment and tested for signs of present or past life and biological hazards. It is recommended that "Controlled distribution of unsterilized materials from Mars should occur only if rigorous analyses determine that the materials do not constitute a biological hazard. If any portion of the sample is removed from containment prior to completion of these analyses it should first be sterilized." While sterilization of Mars samples may not be required, an acceptable method must be available before the samples are returned to Earth. The sterilization method should be capable of destroying a wide range of organisms with minimal effects on the geologic samples. A variety of biological sterilization techniques and materials are currently in use, including dry heat, high pressure steam, gases, plasmas and ionizing radiation. Gamma radiation is routinely used to inactivate viruses and destroy bacteria in medical research. Many commercial sterilizers use Co-60 , which emits gamma photons of 1.17 and 1.33 MeV. Absorbed doses of approximately 1 Mrad (10(exp 8) ergs/g) destroy most bacteria. This study investigates the effects of lethal doses of Co-60 gamma radiation on materials similar to those anticipated to be returned from Mars. The goals are to determine the gamma dose required to kill microorganisms in rock and soil samples and to determine the effects of gamma sterilization on the samples' isotopic, chemical and physical properties. Additional information is contained in the original extended abstract.

    OSIRIS-REx is NASA's third New Frontiers Program mission, following New Horizons that completed a flyby of Pluto in 2015 and the Juno mission to Jupiter that has just begun science operations. The OSIRIS-REx mission's primary objective is to collect pristine surface samples of a carbonaceous asteroid and return to Earth for analysis. Carbonaceous asteroids and comets are 'primitive' bodies that preserved remnants of the Solar System starting materials and through their study scientists can learn about the origin and the earliest evolution of the Solar System. The OSIRIS-REx spacecraft was successfully launched on September 8, 2016, beginning its seven year journey to asteroid 101955 Bennu. The robotic arm will collect 60-2000 grams of material from the surface of Bennu and will return to Earth in 2023 for worldwide distribution by the Astromaterials Curation Facility at NASA Johnson Space Center. The name OSIRIS-REx embodies the mission objectives (1) Origins: Return and analyze a sample of a carbonaceous asteroid, (2) Spectral Interpretation: Provide ground-truth for remote observation of asteroids, (3) Resource Identification: Determine the mineral and chemical makeup of a near-Earth asteroid (4) Security: Measure the non-gravitational that changes asteroidal orbits and (5) Regolith Explorer: Determine the properties of the material covering an asteroid surface. Asteroid Bennu may preserve remnants of stardust, interstellar materials and the first solids to form in the Solar System and the molecular precursors to the origin of life and the Earth's oceans. Bennu is a potentially hazardous asteroid, with an approximately 1 in 2700 chance of impacting the Earth late in the 22nd century. OSIRIS-REx collects from Bennu will help formulate the types of operations and identify mission activities that astronauts will perform during their expeditions. Such information is crucial in preparing for humanity's next steps beyond low Earthy orbit and on to deep space

    The Returned Sample Science Board (RSSB) was established in 2015 by NASA to provide expertise from the planetary sample community to the Mars 2020 Project. The RSSB's first task was to address the effect of heating during acquisition and storage of samples on scientific investigations that could be expected to be conducted if the samples are returned to Earth. Sample heating may cause changes that could ad-versely affect scientific investigations. Previous studies of temperature requirements for returned mar-tian samples fall within a wide range (-73 to 50 degrees Centigrade) and, for mission concepts that have a life detection component, the recommended threshold was less than or equal to -20 degrees Centigrade. The RSSB was asked by the Mars 2020 project to determine whether or not a temperature requirement was needed within the range of 30 to 70 degrees Centigrade. There are eight expected temperature regimes to which the samples could be exposed, from the moment that they are drilled until they are placed into a temperature-controlled environment on Earth. Two of those - heating during sample acquisition (drilling) and heating while cached on the Martian surface - potentially subject samples to the highest temperatures. The RSSB focused on the upper temperature limit that Mars samples should be allowed to reach. We considered 11 scientific investigations where thermal excursions may have an adverse effect on the science outcome. Those are: (T-1) organic geochemistry, (T-2) stable isotope geochemistry, (T-3) prevention of mineral hydration/dehydration and phase transformation, (T-4) retention of water, (T-5) characterization of amorphous materials, (T-6) putative Martian organisms, (T-7) oxidation/reduction reactions, (T-8) (sup 4) He thermochronometry, (T-9) radiometric dating using fission, cosmic-ray or solar-flare tracks, (T-10) analyses of trapped gasses, and (T-11) magnetic studies.

    To examine return to school and classroom performance following traumatic brain injury (TBI). This cross-sectional study set in the community comprised a group of 67 school-age children with TBI (35 mild, 13 moderate, 19 severe) and 14 uninjured matched controls. Parents and children were interviewed and children assessed at a mean of 2 years post injury. Teachers reported on academic performance and educational needs. The main measures used were classroom performance, the Children's Memory Scale (CMS), the Wechsler Intelligence Scale for Children-third edition UK (WISC-III) and the Weschler Objective Reading Dimensions (WORD). One third of teachers were unaware of the TBI. On return to school, special arrangements were made for 18 children (27%). Special educational needs were identified for 16 (24%), but only six children (9%) received specialist help. Two thirds of children with TBI had difficulties with school work, half had attention/concentration problems and 26 (39%) had memory problems. Compared to other pupils in the class, one third of children with TBI were performing below average. On the CMS, one third of the severe group were impaired/borderline for immediate and delayed recall of verbal material, and over one quarter were impaired/borderline for general memory. Children in the severe group had a mean full-scale IQ significantly lower than controls. Half the TBI group had a reading age > or =1 year below their chronological age, one third were reading > or =2 years below their chronological age. Schools rely on parents to inform them about a TBI, and rarely receive information on possible long-term sequelae. At hospital discharge, health professionals should provide schools with information about TBI and possible long-term impairments, so that children returning to school receive appropriate support.

    The Genesis spacecraft was launched on August 8 from Cape Canaveral on a journey to become the first spacecraft to return from interplanetary space. The fifth in NASA's line of low-cost Discovery-class missions, its goal is to collect samples of solar wind and return them to Earth for detailed isotopic and elemental analysis. The spacecraft is to collect solar wind for over two years, while circling the L1 point 1.5 million km sunward of the earth, before heading back for a capsule-style re-entry in September, 2004. After parachute deployment, a mid-air helicopter recovery will be used to avoid a hard landing. The mission has been in the planning stages for over ten years. Its cost, including development, mission operations, and sample analysis, is approximately $209M. The Genesis science team, headed by principal investigator Donald Burnett of Caltech, consists of approximately 20 co-investigators from universities and science centers around the country and internationally. The spacecraft consists of a relatively flat spacecraft bus containing most of the subsystem components, situated below a sample return capsule (SRC) which holds the solar-wind collection substrates and an electrostatic solar wind concentrator. Some of the collectors are exposed throughout the collection period, for a sample of bulk solar wind, while others are exposed only to certain solar wind regimes, or types of flow. Ion and electron spectrometers feed raw data to the spacecraft control and data-handling (C&DH) unit, which determines ion moments and electron flux geometries in real time. An algorithm is used to robotically decide between interstream (IS), coronal hole (CH), and coronal mass ejection (CME) regimes, and to control deployment of the proper arrays to sample these wind regimes independently. This is the first time such a solar-wind decision algorithm has been used on board a spacecraft.

    Product returns are characterized by considerable uncertainty on time and quantity. In the literature on inventory management for product return environments best forecasts of future returns are associated with methods that use the most information regarding product return history. In practice, however, data is often scarce and unreliable, while forecasts based on historical data, reliable or not, are never perfect. In this paper we therefore investigate the impact of imperfect information wi...

  7. Phootprint - A Phobos sample return mission study

    Science.gov (United States)

    Koschny, Detlef; Svedhem, Håkan; Rebuffat, Denis

    Introduction ESA is currently studying a mission to return a sample from Phobos, called Phootprint. This study is performed as part of ESA’s Mars Robotic Exploration Programme. Part of the mission goal is to prepare technology needed for a sample return mission from Mars itself; the mission should also have a strong scientific justification, which is described here. 1. Science goal The main science goal of this mission will be to Understand the formation of the Martian moons Phobos and put constraints on the evolution of the solar system. Currently, there are several possibilities for explaining the formation of the Martian moons: (a) co-formation with Mars (b) capture of objects coming close to Mars (c) Impact of a large body onto Mars and formation from the impact ejecta The main science goal of this mission is to find out which of the three scenarios is the most probable one. To do this, samples from Phobos would be returned to Earth and analyzed with extremely high precision in ground-based laboratories. An on-board payload is foreseen to provide information to put the sample into the necessary geological context. 2. Mission Spacecraft and payload will be based on experience gained from previous studies to Martian moons and asteroids. In particular the Marco Polo and MarcoPolo-R asteroid sample return mission studies performed at ESA were used as a starting point. Currently, industrial studies are ongoing. The initial starting assumption was to use a Soyuz launcher. Uunlike the initial Marco Polo and MarcoPolo-R studies to an asteroid, a transfer stage will be needed. Another main difference to an asteroid mission is the fact that the spacecraft actually orbits Mars, not Phobos or Deimos. It is possible to select a spacecraft orbit, which in a Phobos- or Deimos-centred reference system would give an ellipse around the moon. The following model payload is currently foreseen: - Wide Angle Camera, - Narrow Angle Camera, - Close-Up Camera, - Context camera for

These contracts are closely related to unit--linked life--insurance/savings plan products and can be considered as alternatives to a direct investment in the underlying benchmark portfolio. The option embedded into the savings plan is in fact a power option, and thus the specification of the ``fair'' contract parameters is c...

    Radiating a photon from the initial state provides a useful tool for studying a range of low energy physics using a high-energy e+ e- accelerator. Accurate results require careful calculation of the first order virtual photon corrections. We compare exact results for initial state radiative corrections, finding agreement to an order of 10^{-5} or better as a fraction of the Born cross-section for most of the range of photon energies, at CMS energies relevant in both high-energy collision and radiative return experiments.

    Full Text Available The aim of the study was to analyse the diversity of return on equity in the cooperative banks in Poland in 2010– 2014. The analysis was conducted using data of the Polish Financial Supervision Authority, on the basis of a modifi ed decomposition rate of return on equity. Assessment of the rate of return on equity was made in a size of banks, as determined by the value of assets. In addition, in order to determine the strength and direction of impact the individual components of the model on the formation of return on equity method was applied functional. The study suggests that cooperative banks eff ectively use the equity, because the rate of return on equity was signifi cantly higher than the rate of return on assets. The average return on assets in 2010–2014 was relatively lower in the largest banks and ranged from 0.7–0.9%, and the smallest banks return on assets was approximately 1%. In turn, the return on equity was higher at banks with major assets (over 200 million PLN. In 2013–2014 the rate of return both on assets and equity expressly declined. The main determinants of changes in return on equity were changing the multiplier reduction of profi t from banking activities by operating costs and costs of banking risk and return on assets, as well as measured result on banking activities.

    To examine factors associated with successful return to work among participants in a Social Security Organisation Return To Work programme. Secondary data for 9,850 participants were obtained from the Social Security Organisation Return To Work database. The dependent variable was the Return To Work programme outcome, successful return to employment (same employer or different employer) or unsuccessful return. Logistic regression analysis with weighted sum contrasts was performed to assess the odds ratios with 95% confidence interval (95% CI) for successful return to employment across the various subgroups of participants. Overall, 65.5% of participants successfully returned to employment, either with their former employers or with new employers. Successful return to employment was found to be significantly higher than the overall proportion among those participants who had had commuting accidents, followed by those who had had workplace accidents. Successful return to employment was also associated with injuries of the upper and lower limbs, employers who were interested in hiring disabled workers, motivation to participate in the programme, an intervention period of 3 months or less, age 29 years or younger, and male participants. A structured multidisciplinary intervention programme provides a positive outcome in terms of returning to work. Related factors have various impacts on successful return to work.

    Underexposed photographic negatives were toned with uranium around the turn of the century. Such radioactive photographs permit image transfer by autoradiography, and this confers several new options in photography. It is surprising that about half a century elapsed before the implications of such image transfer were described. The full possibilities of such transfer in processes of intensification, relief imaging, and photographic research are only now being realized.

    The International Space Station (ISS), with its newly attached U.S. Laboratory, Destiny, was photographed by a crew member aboard the Space Shuttle Orbiter Atlantis during a fly-around inspection after Atlantis separated from the Space Station. The Laboratory is shown in the foreground of this photograph. The American-made Destiny module is the cornerstone for space-based research aboard the orbiting platform and the centerpiece of the International Space Station (ISS), where unprecedented science experiments will be performed in the near-zero gravity of space. Destiny will also serve as the command and control center for the ISS. The aluminum module is 8.5-meters (28-feet) long and 4.3-meters (14-feet) in diameter. The laboratory consists of three cylindrical sections and two endcones with hatches that will be mated to other station components. A 50.9-centimeter (20-inch-) diameter window is located on one side of the center module segment. This pressurized module is designed to accommodate pressurized payloads. It has a capacity of 24 rack locations. Payload racks will occupy 15 locations especially designed to support experiments. The Destiny module was built by the Boeing Company under the direction of the Marshall Space Flight Center.

    On Friday, 25 September, CERN opened its doors to nineteen photographers from all over the world for the CERN Photowalk 2015: behind the scenes at the Laboratory.   The photo competition was organised as part of an international photo competition, the Global Physics Photowalk, in which seven other physics laboratories also participated. Professional and amateur photographers alike had the chance to visit and capture for posterity a number of unique CERN sites: Linac4, the main workshop and the ISOLDE facility. They were also able to get a feel for life at CERN by exploring the Meyrin campus. A jury will select the best three photos taken at CERN before the end of October. These photos will be exhibited in 2016 and will represent CERN in the international competition, in which each of the other labs will also enter three snapshots. In November, an international jury and a public vote will pick the winning photos, which will be exhibited in 2016 in Asia, Europe and North America and will be featured ...

    The toilet of Venus is the subject of many paintings. Typically, Venus appears with a small mirror in which her face is visible. Observers tend to say that Venus is admiring herself in a mirror, even when the location of the mirror makes this impossible. We demonstrate that the Venus effect is not specific to paintings by showing that it occurs in real life (Experiment 1) and in photographs (Experiments 1-4). The original description of the effect implied that observers describe Venus as seeing in a mirror what they (the observers) see. We used different photographs to compare the responses when the person in front of the mirror could or could not see him or herself and when the image of his or her face was or was not visible to the observer. Observers tend to state that a person can see his or her own reflection when he or she appears near a mirror, whether or not his or her face is visible in the mirror. A task based on a top-down view of a room confirmed that people lack sensitivity to the role of the viewpoint (Experiment 5). We discuss these findings in relation to other evidence of difficulty in understanding what is visible in a mirror.

    To validate food photographs for food portion size estimation of frequently consumed dishes, to be used in a 24-hour recall food consumption study of pregnant women in a rural environment in Burkina Faso. This food intake study is part of an intervention evaluating the efficacy of prenatal micronutrient supplementation on birth outcomes. Women of childbearing age (15-45 years). A food photograph album containing four photographs of food portions per food item was compiled for eight selected food items. Subjects were presented two food items each in the morning and two in the afternoon. These foods were weighed to the exact weight of a food depicted in one of the photographs and were in the same receptacles. The next day another fieldworker presented the food photographs to the subjects to test their ability to choose the correct photograph. The correct photograph out of the four proposed was chosen in 55% of 1028 estimations. For each food, proportions of underestimating and overestimating participants were balanced, except for rice and couscous. On a group level, mean differences between served and estimated portion sizes were between -8.4% and 6.3%. Subjects who attended school were almost twice as likely to choose the correct photograph. The portion size served (small vs. largest sizes) had a significant influence on the portion estimation ability. The results from this study indicate that in a West African rural setting, food photographs can be a valuable tool for the quantification of food portion size on group level.

  17. A Mars Sample Return Sample Handling System

    2013-01-01

    We present a sample handling system, a subsystem of the proposed Dragon landed Mars Sample Return (MSR) mission [1], that can return to Earth orbit a significant mass of frozen Mars samples potentially consisting of: rock cores, subsurface drilled rock and ice cuttings, pebble sized rocks, and soil scoops. The sample collection, storage, retrieval and packaging assumptions and concepts in this study are applicable for the NASA's MPPG MSR mission architecture options [2]. Our study assumes a predecessor rover mission collects samples for return to Earth to address questions on: past life, climate change, water history, age dating, understanding Mars interior evolution [3], and, human safety and in-situ resource utilization. Hence the rover will have "integrated priorities for rock sampling" [3] that cover collection of subaqueous or hydrothermal sediments, low-temperature fluidaltered rocks, unaltered igneous rocks, regolith and atmosphere samples. Samples could include: drilled rock cores, alluvial and fluvial deposits, subsurface ice and soils, clays, sulfates, salts including perchlorates, aeolian deposits, and concretions. Thus samples will have a broad range of bulk densities, and require for Earth based analysis where practical: in-situ characterization, management of degradation such as perchlorate deliquescence and volatile release, and contamination management. We propose to adopt a sample container with a set of cups each with a sample from a specific location. We considered two sample cups sizes: (1) a small cup sized for samples matching those submitted to in-situ characterization instruments, and, (2) a larger cup for 100 mm rock cores [4] and pebble sized rocks, thus providing diverse samples and optimizing the MSR sample mass payload fraction for a given payload volume. We minimize sample degradation by keeping them frozen in the MSR payload sample canister using Peltier chip cooling. The cups are sealed by interference fitted heat activated memory

  18. Computer aided method for colour calibration and analysis of digital rock photographs

    Full Text Available The methods used in geology to determine colour and colour coverage are expensive, time consuming, and/ or subjective. Estimates of colour coverage can only be approximate since they are based on rough comparisonbased measuring etalons and subjective estimation, which is dependent upon the skill and experience of the person performing the estimation. We present a method which accelerates, simplifis, and objectifis these tasks using a computer application. It automatically calibrates the colours of a digital photo, and enables the user to read colour values and coverage, even after returning from fild work. Colour identifiation is based on the Munsell colour system. For the purposes of colour calibration we use the X-Rite ColorChecker Passport colour chart placed onto the photographed scene. Our computer application detects the ColorChecker colour chart, and fids a colour space transformation to calibrate the colour in the photo. The user can then use the application to read colours within selected points or regions of the photo. The results of the computerised colour calibration were compared to the reference values of the ColorChecker chart. The values slightly deviate from the exact values, but the deviation is around the limit of human capability for visual comparison. We have devised an experiment, which compares the precision of the computerised colour analysis and manual colour analysis performed on a variety of rock samples with the help of geology students using Munsell Rock-color Chart. The analysis showed that the precision of manual comparative identifiation on multicoloured samples is somewhat problematic, since the choice of representative colours and observation points for a certain part of a sample are subjective. The computer based method has the edge in verifibility and repeatability of the analysis since the application the original photo to be saved with colour calibration, and tagging of colouranalysed points and regions.

    The aeroheating environments to vehicles undergoing Mars aerocapture, earth aerocapture from Mars, and earth aerocapture from the moon are presented. An engineering approach for the analysis of various types of vehicles and trajectories was taken, rather than performing a benchmark computation for a specific point at a selected time point in a trajectory. The radiation into Mars using the Mars Rover Sample Return (MRSR) 2-ft nose radius bionic remains a small contributor of heating for 6 to 10 km/sec; however, at 12 km/sec it becomes comparable with the convection. For earth aerocapture, returning from Mars, peak radiation for the MRSR SRC is only 25 percent of the peak convection for the 12-km/sec trajectory. However, when large vehicles are considered with this trajectory, peak radiation can become 2 to 4 times higher than the peak convection. For both Mars entry and return, a partially ablative Thermal Protection System (TPS) would be required, but for Lunar Transfer Vehicle return an all-reusable TPS can be used.

    Prior studies indicate extinguished fear often partially returns when participants are later tested outside the extinction context. Cues carried from the extinction context to the test context sometimes reduce return of fear, but it is unclear whether such extinction cues (ECs) reduce return of fear of public speaking. Here we assessed return of fear of public speaking, and whether either of two types of ECs can attenuate it. Participants gave speeches of increasing difficulty during an exposure practice session and were tested 2 days later in a different context. Testing occurred in the presence of physical ECs, after mentally rehearsing the exposure session, or without either reminder. Practice reduced fear of public speaking, but fear partially returned at test. Neither physical nor mental ECs reduced partial return of fear of public speaking. The return of extinguished fear of public speaking, although small, was reliable, but not appreciably sensitive to presence of ECs. © The Author(s) 2016.

  4. Investment Strategy Based on Aviation Accidents: Are there abnormal returns?

    Directory of Open Access Journals (Sweden)

    Marcos Rosa Costa

    2013-06-01

    Full Text Available This article investigates whether an investment strategy based on aviation accidents can generate abnormal returns. We performed an event study considering all the aviation accidents with more than 10 fatalities in the period from 1998 to 2009 and the stock market performance of the respective airlines and aircraft manufacturers in the days after the event. The tests performed were based on the model of Campbell, Lo & MacKinlay (1997 for definition of abnormal returns, by means of linear regression between the firms’ stock returns and the return of a market portfolio used as a benchmark. This enabled projecting the expected future returns of the airlines and aircraft makers, for comparison with the observed returns after each event. The result obtained suggests that an investment strategy based on aviation accidents is feasible because abnormal returns can be obtained in the period immediately following an aviation disaster.

    We investigate scaling and memory effects in return intervals between price volatilities above a certain threshold q for the Japanese stock market using daily and intraday data sets. We find that the distribution of return intervals can be approximated by a scaling function that depends only on the ratio between the return interval τ and its mean . We also find memory effects such that a large (or small) return interval follows a large (or small) interval by investigating the conditional distribution and mean return interval. The results are similar to previous studies of other markets and indicate that similar statistical features appear in different financial markets. We also compare our results between the period before and after the big crash at the end of 1989. We find that scaling and memory effects of the return intervals show similar features although the statistical properties of the returns are different.

    Although wide-ranging, elusive, large carnivore species, such as the tiger, are of scientific and conservation interest, rigorous inferences about their population dynamics are scarce because of methodological problems of sampling populations at the required spatial and temporal scales. We report the application of a rigorous, noninvasive method for assessing tiger population dynamics to test model-based predictions about population viability. We obtained photographic capture histories for 74 individual tigers during a nine-year study involving 5725 trap-nights of effort. These data were modeled under a likelihood-based, ?robust design? capture?recapture analytic framework. We explicitly modeled and estimated ecological parameters such as time-specific abundance, density, survival, recruitment, temporary emigration, and transience, using models that incorporated effects of factors such as individual heterogeneity, trap-response, and time on probabilities of photo-capturing tigers. The model estimated a random temporary emigration parameter of =K' =Y' 0.10 ? 0.069 (values are estimated mean ? SE). When scaled to an annual basis, tiger survival rates were estimated at S = 0.77 ? 0.051, and the estimated probability that a newly caught animal was a transient was = 0.18 ? 0.11. During the period when the sampled area was of constant size, the estimated population size Nt varied from 17 ? 1.7 to 31 ? 2.1 tigers, with a geometric mean rate of annual population change estimated as = 1.03 ? 0.020, representing a 3% annual increase. The estimated recruitment of new animals, Bt, varied from 0 ? 3.0 to 14 ? 2.9 tigers. Population density estimates, D, ranged from 7.33 ? 0.8 tigers/100 km2 to 21.73 ? 1.7 tigers/100 km2 during the study. Thus, despite substantial annual losses and temporal variation in recruitment, the tiger density remained at relatively high levels in Nagarahole. Our results are consistent with the hypothesis that protected wild tiger populations can remain

    Phobos Sample Return is a mission currently studied by the European Space Agency (ESA), in collaboration with Russia. The main scientific goal is to return about 100 g of sample from the Martian moon Phobos. The current ESA Phase A study has identified a feasible mission with a launch in Sep 2024. It would arrive at Mars in Aug 2025, land on Phobos in April 2026, escape from Mars in September 2026 and bring back a sample to Earth in the summer of 2027. The spacecraft consists of a Propulsion Module (PM), a Lander Module (LM), an Earth Return Vehicle (ERV), and an Earth Reentry Capsule (ERC). A sampling Acquisition Transfer and Containment system (SATCS) composed of a robotic arm, sampling and sealing mechanism is responsible for the surface sampling operations. The PM is responsible for bringing the whole S/C composite into Mars orbit. The Lander/ERV/ERC composite would separate from the PM after Mars Orbit Insertion. After a phase of 1 month spent observing Deimos from a quasi-satellite orbit, the composite would be transferred to Phobos' vicinity for an extensive phase of detailed surface characterization which would allow the selection of the candidate landing site. The S/C would then land on Phobos and remain on the surface for a few weeks. After some initial characterization of the surroundings, the sample would be taken and transferred to the ERC. The ERV with the ERC would leave Phobos and return to Earth; the LM would continue performing surface science on Phobos until several weeks after ERV departure. Shortly before atmospheric entry, the ERC would separate from the ERV to enter the atmosphere safely. After recovery, the sample would be returned into an analysis lab. This presentation will give the latest status of the mission study, and outline future activities.

    Full Text Available Although it was released in the summer of 1990, the concept of reengineering returns in actuality, because in the social and economic conditions that we are experiencing at the moment, to face the increasingly fierce competition more and more companies have to resort to redesign the processes. Throughout this article, after a brief introduction, we will present the factors that contributed to the occurrence of reengineering; trying to highlight what involves this concept, the characteristics of the processes resulted from the reengineering, the importance and methods to prepare a process map, and the method to launch the process redesign. Finally we have issued several opinions and have made a number of recommendations that will lead to achieving a qualitative leap targeted by the companies which resort to reengineering.

    2015-07-15

    Femoroacetabular impingements (FAI) are quite frequent among young athletes. An early detection is essential in order to prevent more labral and cartilage damage. Conservative treatment should not focus on forcing the full range of motion but on restoring a good muscle balance around the joint and a better lower limb dynamic stability and control. The patient should be educated to master the end of hip range of motion during his activities. If the outcome is not satisfactory, a surgical treatment is offered. The post-operative treatment protocol is tailored to the type of repair, following several stages, from neuromuscular control to strengthening up to the return to sport. FAI prevention should be more studied in order to protect the hip of the growing athlete.

    The renovation work on the Users Office, which began on 29 November, was completed last week. The Office's staff have now returned to their modernised and more spacious premises in Building 61. For four months, the Users' Office was housed in Building 2-R-030 thanks to the LHCb experiment collaboration, which was kind enough to temporarily loan some office space. For 15 years, the team has been helping Users with their administrative tasks. It provides them with all the information necessary on the procedures to be followed after their arrival at CERN as well as on cultural activities in the region. Since the beginning of January, the team is also looking after the Unpaid Associates. CERN hosts 4489 Users from Member States and 1909 from non-Members States, representing over 50 nationalities.

  12. Persistent diarrhea in the returned traveler.

    Thielman, N M; Guerrant, R L

    1998-06-01

    In conclusion, the causes of chronic diarrhea in the returned traveler are protean. Careful evaluation requires an understanding of where the traveler has been, when they were there, the type of diarrheal illness, medications taken, and knowledge of the patients' other medical problems. Protozoa, particularly G. lamblia, C. parvum, and C. cayatenensis, are among the more commonly identified agents. If the patient is immunocompromised, microsporidia and Isospora become more likely, and a prior history of antimicrobial use raises the possibility of C. difficile colitis. Occasionally helminths, which establish intimate contact with the intestinal mucosa, may also cause prolonged diarrhea. If these and other gastrointestinal insults, such as tropical sprue, small bowel overgrowth, lactose intolerance, and processes unrelated to travel are excluded by more invasive studies or clinical history, the patient can be reassured that idiopathic chronic diarrhea is usually self-limited.

    This case study is a report of a rehabilitative employment program that used trauma focused group treatment with individuals who suffered from Posttraumatic Stress Disorder (PTSD) post 9/11. The program was developed in order to assist them to return to the work force. These Individuals lost their jobs because of the 9/11 terrorist attack and experienced financial difficulty, yet because of their PTSD symptoms, had difficulty seeking employment. Individuals were selected for group treatment based on the presence of PTSD symptoms as measured by The Posttraumatic Stress Diagnostic Scale, an external locus of control determined by the Internal and External Locus of Control Scale, low self-esteem as per the Self-Efficacy Scale, and hopelessness, as assessed through the Hopelessness Scale. Additional assessments (Role Checklist, Psychiatric Rehabilitation Determination, Vocational Sentence Completion, Activity Record of the Occupational Questionnaire, and an interview that included a work history) were administered by an occupational therapist. Results of these assessments were used to inform group co-leaders (one social worker and one occupational therapist per group) of their members' symptoms, coping mechanisms, attitudes towards work, rehabilitation readiness, life roles and values, and use of time in order to plan appropriate group intervention. Groups met for once-a-week 90 minute sessions. Group leaders used restructuring and systematic prolonged exposure to encourage group members to describe their traumatic experiences in order to neutralize negative affect states, mange symptoms, and work through guilt and distorted perceptions. Members attended until they began gainful employment. Descriptive data revealed that during the first year of the program, 9/11/2001-9/11/2002, 262 of the 3,567 clients seen (13.6%) returned to the work force.

  14. The Fifth Slovene Hamlet: Return to Tradition?

    Directory of Open Access Journals (Sweden)

    Moe Marija Zlatnar

    2017-12-01

    Full Text Available Over the nearly two centuries that Hamlet has been a fixture of the Slovene cultural firmament, the complete text has been translated five times, mostly by highly esteemed figures of Slovene literature and literary translation. This article focuses on the most recent translation, which was done by the prominent Slovene drama translator Srečko Fišer for a performance at the National Theatre in Ljubljana in 2013. It examines the new translation’s relations to its source text as well as to the previous translations. After the late twentieth century, when Hamlet was regarded as a text to be challenged, this new translation indicates the return to the tradition of reverence both for the source text and its author, and for the older translations. This is demonstrated on all levels, from the choice of source text edition, which seems to bear more similarities with the older translations than with the most recent predecessors, to the style, which echoes the solutions used by the earlier translators. Fišer continues the Slovenian tradition to a far greater extent than the two translators twenty years ago, by using the same strategies as the early translators, not fixing what was not broken, and only adding his own interpretation to the existing ones, instead of challenging or ignoring them. At the same time, however, traces of subversion of the source text can be detected, not in the form of rebellion, but rather as a mild disregard. This latest translation is the first one to frequently reshuffle the text. It is also the first to subordinate meaning to style. This all indicates that despite the apparent return to tradition, the source text is no longer treated with the reverence of the past.

  15. The return of highlyskilled migrants to Serbia

    Directory of Open Access Journals (Sweden)

    Bodrožić Zlatko

    2014-01-01

    Full Text Available Migration scholars argue that return migrants have the potential to become a developing force in their countries of origin, but that the realization of this 'diaspora solution to innovation capacity development' depends on different context factors. This paper contributes to capturing theoretically such context factors by making use of concepts of the Cultural-Historical Activity Theory. Based on an explorative empirical approach, a model of processes of return migration in a specific country (Serbia is created. According to the findings of this paper, returnees offer potential for Serbian transnational innovation systems, which subsequently could strongly contribute to the social and economic development of Serbia. However, at present, the developmental potential of highly skilled returnees in Serbia has not bee realized yet. Returnees arrive with hopes to earn a living in Serbia and possibly to contribute to the development of the society. Still, there are many barriers for returnees, such as nepotism, as well as the existing power structures at potential workplaces and markets. At the same time, state institutions or independent organizations do not provide sufficient support to make a difference for the majority of returnees. Although there are some examples of returnees who are successful in developing innovative start-ups or becoming innovators in the existing organizations, their number remains limited. Nevertheless, it seems possible that returnees can become a developing force in Serbia and similar countries in transition. In order to realize this, the establishment of a sustainable support system for highly skilled returnees to Serbia and scientific diaspora members is needed.

  16. Comparing humans to automation in rating photographic aesthetics

    Kakarala, Ramakrishna; Agrawal, Abhishek; Morales, Sandino

    2015-03-01

    Computer vision researchers have recently developed automated methods for rating the aesthetic appeal of a photograph. Machine learning techniques, applied to large databases of photos, mimic with reasonably good accuracy the mean ratings of online viewers. However, owing to the many factors underlying aesthetics, it is likely that such techniques for rating photos do not generalize well beyond the data on which they are trained. This paper reviews recent attempts to compare human ratings, obtained in a controlled setting, to ratings provided by machine learning techniques. We review methods to obtain meaningful ratings both from selected groups of judges and also from crowd sourcing. We find that state-of-the-art techniques for automatic aesthetic evaluation are only weakly correlated with human ratings. This shows the importance of obtaining data used for training automated systems under carefully controlled conditions.

    2013-03-01

    During the 1920s and 1930s, Viennese physicist Marietta Blau (1894-1970) pioneered the use of photographic methods for imaging high-energy nuclear particles and events. In 1937 she and Hertha Wambacher discovered "disintegration stars" - the tracks of massive nuclear disintegrations - in emulsions exposed to cosmic radiation. This discovery launched the field of particle physics, but Blau's contributions were underrecognized and she herself was nearly forgotten. I trace Blau's career at the Institut für Radiumforschung in Vienna and the causes of this "forgetting," including her forced emigration from Austria in 1938, the behavior of her colleagues in Vienna during and after the National Socialist period, and the flawed Nobel decision process that excluded her from a Nobel Prize.

    Full Text Available The main objective of this paper is analyze the changes occurred in the practices of the society point of view using images from pictorial and different techniques of engraving and trying, also, to understand how after the advent of photography in the second quarter of the nineteenth century, changes occurs in the visual schemes present in this society. It is well know, with the spread of photography as art, has changed people's relationship with the images, not only in artistic and aesthetic prisms, but in social, cultural and political. This work traces a panorama of photograph trajectory and explicit its relationship to art and education, based in Boris Kossoy and Rosalind Krauss theory’s, seeking to draw a historical-cultural panorama of photography, and also with François Soulages when it comes to aesthetic research on photography. This work use Cerqueira and Barros propositions to think about the relationship between photography and education.

  1. The Framing Safety Project: photographs and narratives by battered women.

    Science.gov (United States)

    Frohmann, Lisa

    2005-11-01

    This article describes the Framing Safety Project that the author developed to do collaborative, community action/education research with battered women about the meaning of safety in their lives. The project is built on the use of participant-generated photographs and photo-elicitation interviews as methods for exploring with women, in support group settings, the meanings of violence in their lives and their approaches to creating safer spaces. Although visual sociologists have used variations of these methods, particularly to study the experiences of children, the author combines them in a uniquely feminist approach that leads from the women's photography and interviews to a community education and action component. The author describes the process of developing and implementing this project with Mexican and South Asian immigrant women and discusses the ways in which its methodological approach serves to amplify the voices of silenced women, and to offer opportunities for community education and social action.

  2. Liminal transformations: folding the surface of the photograph

    Directory of Open Access Journals (Sweden)

    Nour Dados

    2010-04-01

    Full Text Available At once a material object and a multitude of paths, the photograph is a useful place to begin thinking about the threshold. In the photograph we might dwell on the nuances of the threshold, its ability to be an ‘inbetween’ and a gateway to a ‘beyond’ simultaneously. Indeed, the photograph offers both possibilities. The work of Bhabha, Benjamin and Sontag elucidates this slippage. In this uncertainty, ‘inbetween’ and ‘beyond’ signal another productive intersection.  The liminality of the threshold marks this terrain as a spatial transgression that ushers in a temporal disjuncture. The threshold is a shadow zone, as ordinary as a stairwell and as transformative as a breakthrough. In attempting to map the threshold, the paper borrows from Deleuze and Marks on enfolding and unfolding as a means through which knowledge becomes accessible, or remains concealed. To some extent, mapping the threshold is a process that begins unfolding from the discussion of surface, gaze and perception. Yet despite these markers, mapping the threshold of photographs proves difficult and elusive. In this respect, Wittgenstein’s notion of ‘seeing aspects’ helps explain the way that the threshold always exceeds our attempts at mapping and defies perception. The paper examines this impasse through the ‘fold of the surface’, an action which transgresses the flatness of the image without altering it. Perhaps this is the closest we can be to the threshold without holding it.À la fois objet matériel et multitude de chemins, la photographie est un lieu privilégié pour commencer à réfléchir sur le seuil. Dans la photo, nous pouvons nous attarder sur les nuances du seuil, son caractère simultané d’« entre-deux » et de portail vers un « au-delà » en même temps. En effet, la photo offre en effet ces deux possibilités. Les travaux de Bhabha, Benjamin et Sontag éclaircissent ce glissement. Dans cet incertain, l’« entre-deux » et

    To develop a classification and grading system for myopic maculopathy. Development and evaluation of a classification system for myopic maculopathy based on observational case series. A comprehensive set of myopic macular lesions was defined via literature review and through consensus meetings among retinal specialists and clinician scientists. A classification of myopic maculopathy was formulated based on fundus photographs and a modified Delphi process and consensus. Inter- and intraobserver reproducibility, assessed as agreement (%) and weighted kappa values, were evaluated. One hundred retinal photographs with myopia and myopic macular lesions were selected from case series at the High Myopia Clinic of the Tokyo Medical and Dental University, Tokyo, Japan. We defined 5 categories of myopic maculopathy including "no myopic retinal degenerative lesion" (Category 0), "tessellated fundus" (Category 1), "diffuse chorioretinal atrophy" (Category 2), "patchy chorioretinal atrophy" (Category 3), and "macular atrophy" (Category 4). Three additional features to supplement these categories were defined as "plus" lesions, namely, lacquer cracks, myopic choroidal neovascularization, and Fuchs spot. Posterior staphyloma was considered as a further, important sign of myopic retinopathy. The intraobserver agreement was ≥85% and the corresponding weighted kappa statistic was ≥0.6 between observations. After a brief training session, interobserver kappa statistics reached the predefined satisfactory level (≥0.4), considered as above moderate agreement. We propose a classification system for myopic maculopathy that was found to be reproducible. Applying a uniform classification in different studies will facilitate communication and comparison of findings from clinical trials and epidemiologic studies. Copyright © 2015 Elsevier Inc.

    2017-07-18

    To systemically review all studies reporting return to sport following tibial plateau fracture, in order to provide information on return rates and times to sport, and to assess variations in sporting outcome for different treatment methods. A systematic search of CINAHAL, Cochrane, EMBASE, Google Scholar, MEDLINE, PEDro, Scopus, SPORTDiscus and Web of Science was performed in January 2017 using the keywords "tibial", "plateau", "fractures", "knee", "athletes", "sports", "non-operative", "conservative", "operative", "return to sport". All studies which recorded return rates and times to sport following tibial plateau fractures were included. Twenty-seven studies were included: 1 was a randomised controlled trial, 7 were prospective cohort studies, 16 were retrospective cohort studies, 3 were case series. One study reported on the outcome of conservative management (n = 3); 27 reported on the outcome of surgical management (n = 917). Nine studies reported on Open Reduction Internal Fixation (ORIF) (n = 193), 11 on Arthroscopic-Assisted Reduction Internal Fixation (ARIF) (n = 253) and 7 on Frame-Assisted Fixation (FRAME) (n = 262). All studies recorded "return to sport" rates. Only one study recorded a "return to sport" time. The return rate to sport for the total cohort was 70%. For the conservatively-managed fractures, the return rate was 100%. For the surgically-managed fractures, the return rate was 70%. For fractures managed with ORIF, the return rate was 60%. For fractures managed with ARIF, the return rate was 83%. For fractures managed with FRAME was 52%. The return rate for ARIF was found to be significantly greater than that for ORIF (OR 3.22, 95%CI: 2.09-4.97, P FRAME (OR 4.33, 95%CI: 2.89-6.50, P FRAME (OR 1.35, 95%CI: 0.92-1.96, P = 0.122). The recorded return time was 6.9 mo (median), from a study reporting on ORIF. Return rates to sport for tibial plateau fractures remain limited compared to other fractures. ARIF provides the best return rates. There

  5. Scene correction (precision techniques) of ERTS sensor data using digital image processing techniques

    1974-01-01

    Techniques have been developed, implemented, and evaluated to process ERTS Return Beam Vidicon (RBV) and Multispectral Scanner (MSS) sensor data using digital image processing techniques. The RBV radiometry has been corrected to remove shading effects, and the MSS geometry and radiometry have been corrected to remove internal and external radiometric and geometric errors. The results achieved show that geometric mapping accuracy of about one picture element RMS and two picture elements (maximum) can be achieved by the use of nine ground control points. Radiometric correction of MSS and RBV sensor data has been performed to eliminate striping and shading effects to about one count accuracy. Image processing times on general purpose computers of the IBM 370/145 to 168 class are in the range of 29 to 3.2 minutes per MSS scene (4 bands). Photographic images of the fully corrected and annotated scenes have been generated from the processed data and have demonstrated excellent quality and information extraction potential.

  6. Females are sensitive to unpleasant human emotions regardless of the emotional context of photographs.

    2017-06-09

    Previous studies have demonstrated that females exhibit higher sensitivity than males to the emotional state of a person in a photograph. The present study examined whether such females' sensitivity to human emotions could be observed even when the background emotional contexts were incongruent with facial expressions. The late positive potential (LPP) was measured while 19-female and 15-male participants viewed a photograph of a face with varied emotional expressions (pleasant, neutral, or unpleasant) superimposed on a background photograph with varied valences (pleasant, neutral, or unpleasant). The results showed that unpleasant background photographs elicited a larger LPP compared to pleasant and neutral background photographs in both female and male participants. In contrast, a larger LPP for the unpleasant face photographs was observed only in female participants. Furthermore, the effect of face photographs did not interact with the effect of background photographs. These results suggest that females are sensitive to human emotions regardless of the emotional context. Copyright © 2017 Elsevier B.V. All rights reserved.

    Patients with diabetic foot disease require frequent screening to prevent complications and may be helped through telemedical home monitoring. Within this context, the goal was to determine the validity and reliability of assessing diabetic foot infection using photographic foot imaging and infrared thermography. For 38 patients with diabetes who presented with a foot infection or were admitted to the hospital with a foot-related complication, photographs of the plantar foot surface using a photographic imaging device and temperature data from six plantar regions using an infrared thermometer were obtained. A temperature difference between feet of >2.2 °C defined a "hotspot." Two independent observers assessed each foot for presence of foot infection, both live (using the Perfusion-Extent-Depth-Infection-Sensation classification) and from photographs 2 and 4 weeks later (for presence of erythema and ulcers). Agreement in diagnosis between live assessment and (the combination of ) photographic assessment and temperature recordings was calculated. Diagnosis of infection from photographs was specific (>85%) but not very sensitive (90%) but not very specific (60%) and specific (>79%). Intra-observer agreement between photographic assessments was good (Cohen's κ=0.77 and 0.52 for both observers). Diagnosis of foot infection in patients with diabetes seems valid and reliable using photographic imaging in combination with infrared thermography. This supports the intended use of these modalities for the home monitoring of high-risk patients with diabetes to facilitate early diagnosis of signs of foot infection.

    The purpose of this paper was to examine the validity and reliability of using photographs of wounds to accurately assess wound status. The results of assessing wound appearance using wound photographs was compared to results obtained from a bedside assessment using the Pressure Sore Status Tool (PSST). The photographic wound assessment tool (PWAT) used in this comparison represents a modified version of the PSST and includes the six domains that can be determined from wound photographs. The PWAT was used on photographs of both chronic pressure ulcers (n = 56) and leg ulcers due to vascular insufficiency (n = 81). The photographic tool has excellent intrarater (ICC = 0.96) and interrater (ICC = 0.73) reliability and good concurrent validity (r = 0.70) compared with a full bedside assessment PSST. The PWAT has also shown to be sensitive to change in wound appearance of healing ulcers, but not nonhealing ulcers. These results would suggest that in the event that a full bedside assessment is not possible, wound photographs may be used to accurately assess wound appearance of both chronic pressure ulcers located on the trunk and vascular ulcers of the lower extremity. Establishing a valid and reliable assessment of wound healing using photographic images is of great relevance to the advancing fields of computer image analysis and telemedicine.

    Full Text Available Although it was one of the most important events in the history of palaeoanthropology, many details of the Taung discovery and the events that followed it are still not completely elucidated. In this paper, we recount the events surrounding three early photographs (stored in the University of the Witwatersrand Archives showing the Taung Child skull being held in the hands of the renowned anthropologist Raymond Dart. Having, what seems to be, a mosaic of evidence both for and against, we deliberate upon whether the archival photographs presented here are among the first photographs of the fossil itself or are of the first plaster cast of the Taung Child which was prepared for the 1925 British Empire Exhibition held at Wembley, London. We interpreted the photographs and determined their provenance through analyses which included historical examination of published accounts of the Taung discovery and archival materials, as well as comparisons of the photographed material in question with both archival and current (digital, high quality photographs of the Taung fossil itself and Taung skull casts (as the skull underwent changes over time. We conclude that the early photographs presented here are of the original fossil itself and not of a cast. At the same time, these photographs represent some of the first pictorial depictions of the Taung Child skull.

    An objective tool quantifying the toxicity of 5-fluorouracil (5-FU) from photographs was recently reported, and its reliability was confirmed. The aim of this study was to validate the photograph-based toxicity score. Photograph-based toxicity scores of participants assigned to the 5-FU arm of a randomized placebo-controlled trial were tested for correlations with their patient-reported symptom scores and baseline characteristics. Each pair of individual and overall scores of patient-reported symptoms and photograph-based toxicity was correlated at 2 and 4 weeks (correlation coefficient range, 0.34-0.95; P photograph-based 5-FU toxicity score. The tool can be used to objectively measure 5-FU toxicity in clinical or research setting, and it can be a prototype for toxicity measurements of other topical medications. © The Author(s) 2016.

    The U.S. Geological Survey (USGS) conducts baseline and storm response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms (Morgan, 2009). On February 7, 2012, the USGS conducted an oblique aerial photographic survey from Pensacola, Fla., to Breton Islands, La., aboard a Piper Navajo Chieftain at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was flown to collect baseline data for assessing incremental changes since the last survey, and the data can be used in the assessment of future coastal change. The photographs provided here are Joint Photographic Experts Group (JPEG) images. The photograph locations are an estimate of the position of the aircraft and do not indicate the location of the feature in the images (see the Navigation Data page). These photos document the configuration of the barrier islands and other coastal features at the time of the survey. The header of each photo is populated with time of collection, Global Positioning System (GPS) latitude, GPS longitude, GPS position (latitude and longitude), keywords, credit, artist (photographer), caption, copyright, and contact information using EXIFtools (Subino and others, 2012). Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet. Table 1 provides detailed information about the assigned location, name, data, and time the photograph was taken along with links to the photograph. In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on either the thumbnail or the link above the thumbnail. The KML files were created using the photographic navigation files (see the Photos and Maps page).

  7. Precautionary Principle and Mars Sample Return

    Science.gov (United States)

    Arnould, Jacques

    Many space missions have today as an aim the exploration and the knowledge of the planet Mars; consequently, the return of Martian samples seems one of the next possible stages, at the horizon of about fifteen years. Devoted in the search of traces of life, passed or presents, such a mission presents a true stake not only from the scientific point of view but also from the ethical. Right now, the COSPAR specified the precautions to be taken to avoid or, at the very least, to limit the risk of contamination of the terrestrial biosphere by pathogenic the hitherto unknown ones. Are these recommendations sufficient? Do they concern only the scientific prudence or take truly counts of the good of humanity and the life on Earth? In the final analysis, is the incurred risk, even weak, to endanger this life worth the sorrow of it? Hitherto confined with the scientific circles of astronomy and astrobiology, this questioning could move the public opinion and this one would undoubtedly call some with the principle of precaution. In what this recourse would be relevant? The precaution aims indeed the hypothetical risks, not yet confirmed scientifically, but of which the possibility can be identified starting from empirical and scientific knowledge; such is well the case. But is it for as much possible to apply this principle to the case of the Martian samples, insofar as the objective of such a mission remains for the strictly scientific moment? Is it possible to manage the risks in the same manner when it is a question of appropriation and exploitation of the natural resources and energy (GMO, nuclear energy, etc.) and when it acts, in the case of Mars, that only search of the knowledge? How to manage the fundamental difference between the risks voluntarily taken and arbitrarily imposed, clarified and keep silent? The case of the return of the samples leads to the borders of the contemporary interrogations on the stakes and the benefits of science, on the share of risk

    2003-01-01

    This project involved the analysis of potential landing sites on Mars. As originally proposed, the project focused on landing sites from which samples might be returned to Earth. However, as the project proceeded, the emphasis shifted to missions that would not include sample return, because the Mars Exploration Program had deferred sample returns to the next decade. Subsequently, this project focused on the study of potential landing sites for the Mars Exploration Rovers.

    For survival and development, autonomous agents in complex adaptive systems involving the human society must compete against or collaborate with others for sharing limited resources or wealth, by using different methods. One method is to invest, in order to obtain payoffs with risk. It is a common belief that investments with a positive risk-return relationship (namely, high risk high return and vice versa) are dominant over those with a negative risk-return relationship (i.e., high risk low ...

    probability that cash flows or return will vary from expectations. Standard corporate finance theory supposes that a company chooses a capital structure that maximizes company value. A fundamental idea in finance is the relationship between risk and return. The greater the amount of risk that an investor is willing to take on, the greater the potential return. The reason for this is that investors need to be compensated for taking on additional risk. Why put capital at significant risk for a ...

    In the last decades, countries in Latin America and the Caribbean have experienced a dramatic increase in the levels of higher education enrollment. Using administrative data from Chile and Colombia, we find that this phenomenon is not always associated with higher private individual returns. In both countries, there is a significant dispersion in the net returns to higher education and a significant proportion of graduates could be facing negative returns. This means that, for many higher ed...

  15. Market Skewness Risk and the Cross Section of Stock Returns

    DEFF Research Database (Denmark)

    Young Chang, Bo; Christoffersen, Peter F.; Jacobs, Kris

    2013-01-01

    The cross section of stock returns has substantial exposure to risk captured by higher moments of market returns. We estimate these moments from daily Standard & Poor's 500 index option data. The resulting time series of factors are genuinely conditional and forward-looking. Stocks with high...... exposure to innovations in implied market skewness exhibit low returns on average. The results are robust to various permutations of the empirical setup. The market skewness risk premium is statistically and economically significant and cannot be explained by other common risk factors such as the market...... excess return or the size, book-to-market, momentum, and market volatility factors, or by firm characteristics....

  16. Risk-Return Trade-Off for European Stock Markets

    DEFF Research Database (Denmark)

    Aslanidis, Nektarios; Christiansen, Charlotte; Savva, Christos S.

    This paper adopts dynamic factor models with macro-finance predictors to revisit the intertemporal risk-return relation in five large European stock markets. We identify country specific, Euro area, and global factors to determine the conditional moments of returns considering the role of higher......-order moments as additional measures of risk. The preferred combination of factors varies across countries. In the linear model, there is a strong but negative relation between conditional returns and conditional volatility. A Markov switching model describes the risk-return trade-off well. A number...... of variables have explanatory power for the states of the European stock markets....

    Elderly migrants constitute a considerable share of global return migration; nevertheless, literature on the health aspects of the return migration among these migrants is still scarce. This study explores the significance of return migration among elderly, chronically ill Bosnian refugees from...... Denmark and the role of health issues in their decision to return. It is based on semi-structured interviews with 33 elderly, chronically ill Bosnian refugees who have moved back to Bosnia and Herzegovina, and 10 elderly, chronically ill Bosnian refugees who have remained in Denmark. The interviews show...

  18. Influence of product return lead-time on inventory control

    International audience; We consider a production-inventory system with capacity constraint and item returns correlated to demand. The system is modelled by an M/M/1 make-to-stock queue with lost sales. A satisfied demand incurs an item return with a certain probability, after an exponentially distributed return lead-time. We distinguish two cases: When the number of items to be returned is observable and when it is not observable. For the first case, we partially characterize the optimal policy...

    Full Text Available BACKGROUND: To convert first-time blood donors into regular volunteer donors is a challenge to transfusion services. OBJECTIVES: This study aims to estimate the return rate of first time donors of the Ribeirão Preto Blood Center and of other blood centers in its coverage region. METHODS: The histories of 115,553 volunteer donors between 1996 and 2005 were analyzed. Statistical analysis was based on a parametric long-term survival model that allows an estimation of the proportion of donors who never return for further donations. RESULTS: Only 40% of individuals return within one year after the first donation and 53% return within two years. It is estimated that 30% never return to donate. Higher return rates were observed among Black donors. No significant difference was found in non-return rates regarding gender, blood type, Rh blood group and blood collection unit. CONCLUSIONS: The low percentage of first-time donors who return for further blood donation reinforces the need for marketing actions and strategies aimed at increasing the return rates.

  20. Return migration to Jamaica and its development potential.

    The return of migrants to Jamaica is closely associated with the persistence of the transnational household, which is established between the family members abroad and those who remain in Jamaica. The strength of transnational linkages is strongly determined by the manner and purpose of migration, by whether the migration involves an individual or a family, and the extent of the migrant's obligations in compensation for the neglect of responsibilities during his or her absence. Remittances precede, accompany, and follow the return of migrants. There was a consistent increase in remittances during the 1990s; they increased in revenue from US$183.3 million in 1991 to US$668.7 million in 1997. Quantitative statistics on return migration to Jamaica have only been gathered officially since 1992. Data showed a steady increase in the volume of return migration from 1992 to 1997. The largest numbers of returning residents were recorded in 1993 (2493) and in 1994 (2417). The majority of the migrants came from the US followed by the UK. A smaller percentage of return migrants came from Canada and other locations, chiefly Caribbean countries. Seeing potential in the Jamaican overseas community, the Government of Jamaica has established programs, such as the Return of Talent program, to encourage the return of its nationals. Two factors have had an impact on return migration to Jamaica: 1) the characteristics of the migrants in terms of skill level, experience, and attitudes and 2) the social and economic condition of the country itself.
