The geometric algebra produces the new fields of view in the modern mathematical physics, definition of bodies and rearranging for equations of mathematics and physics. The new mathematical approaches play an important role in the progress of physics. After presenting Clifford algebra and quarantine's, the symmetry operations with Clifford algebra and quarantine's are defined. This symmetry operations are applied to a Platonic solids, which are called as tetrahedron, cube, octahedron, icosahedron and dodecahedron. Also, the vertices of Platonic solids presented in the Cartesian coordinates are calculated

6. Platonic solids back in the sky: icosahedral inflation

International Nuclear Information System (INIS)

Kang, Jonghee; Nicolis, Alberto

2016-01-01

We generalize the model of solid inflation to an anisotropic cosmic solid. Barring fine tunings, the observed isotropy of the cosmological background and of the scalar two-point function isolate the icosahedral group as the only possible symmetry group of such a solid. In such a case, higher-point correlation functions—starting with the three-point one—are naturally maximally anisotropic, which makes the standard detection strategies highly inefficient and calls for a dedicated analysis of CMB data. The tensor two-point function can also be highly anisotropic, but only in the presence of sizable higher-derivative couplings

8. α clustering with a hollow structure: Geometrical structure of α clusters from platonic solids to fullerene shape

Science.gov (United States)

Tohsaki, Akihiro; Itagaki, Naoyuki

2018-01-01

We study α -cluster structure based on the geometric configurations with a microscopic framework, which takes full account of the Pauli principle, and which also employs an effective internucleon force including finite-range three-body terms suitable for microscopic α -cluster models. Here, special attention is focused upon the α clustering with a hollow structure; all the α clusters are put on the surface of a sphere. All the platonic solids (five regular polyhedra) and the fullerene-shaped polyhedron coming from icosahedral structure are considered. Furthermore, two configurations with dual polyhedra, hexahedron-octahedron and dodecahedron-icosahedron, are also scrutinized. When approaching each other from large distances with these symmetries, α clusters create certain local energy pockets. As a consequence, we insist on the possible existence of α clustering with a geometric shape and hollow structure, which is favored from Coulomb energy point of view. Especially, two configurations, that is, dual polyhedra of dodecahedron-icosahedron and fullerene, have a prominent hollow structure compared with the other six configurations.

11. Socrates: Platonic Political Ideal

Directory of Open Access Journals (Sweden)

Christopher P. Long

2012-08-01

Full Text Available This essay articulates the differences and suggests the similarities between the practices of Socratic political speaking and those of Platonic political writing. The essay delineates Socratic speaking and Platonic writing as both erotically oriented toward ideals capable of transforming the lives of individuals and their relationships with one another. Besides it shows that in the Protagoras the practices of Socratic political speaking are concerned less with Protagoras than with the individual young man, Hippocrates. In the Phaedo, this ideal of a Socrates is amplified in such a way that Platonic writing itself emerges as capable of doing with readers what Socratic speaking did with those he encountered. Socrates is the Platonic political ideal. The result is a picture of the transformative political power of Socratic speaking and Platonic writing both.

Ostenfeld, Erik Nis

2011-01-01

Artiklen falder i to dele, en metodisk del og en gennemgang af hovedpunkter i Platons filosofi. Det er almindelig viden blandt oplyste, uddannede mennesker, at Platon er en af de vigtigste filosoffer overhovedet i den vesterlandske kultur. Dette illustreres af den indflydelse på filosofi......, litteratur og kultur, han har haft i de 2500 år, der er gået, siden han levede. Man mener også at vide, at Platons filosofi bl.a. indeholder forestillinger om en ideverden og en udødelig sjæl, der midlertidigt er havnet i en distraherende uvirkelig skyggeverden. Ved filosofiens hjælp kan den vende tilbage...... til skuet af ideerne. Hertil hører også billedet af den tredelte sjæl som en kusk med vognspand af to mere eller mindre uregerlige heste. Endelig er Platon forbundet med ideen om en idealstat regeret af filosoffer. Skønt alle disse forestillinger findes i Platons værk, er det ikke korrekt at antage...

17. Cutting solid figures by plane - analytical solution and spreadsheet implementation

Science.gov (United States)

Benacka, Jan

2012-07-01

In some secondary mathematics curricula, there is a topic called Stereometry that deals with investigating the position and finding the intersection, angle, and distance of lines and planes defined within a prism or pyramid. Coordinate system is not used. The metric tasks are solved using Pythagoras' theorem, trigonometric functions, and sine and cosine rules. The basic problem is to find the section of the figure by a plane that is defined by three points related to the figure. In this article, a formula is derived that gives the positions of the intersection points of such a plane and the figure edges, that is, the vertices of the section polygon. Spreadsheet implementations of the formula for cuboid and right rectangular pyramids are presented. The user can check his/her graphical solution, or proceed if he/she is not able to complete the section.

2011-01-01

This study addresses a central theme in current philosophy: Platonism vs Naturalism and provides accounts of both approaches to mathematics, crucially discussing Quine, Maddy, Kitcher, Lakoff, Colyvan, and many others. Beginning with accounts of both approaches, Brown defends Platonism by arguing that only a Platonistic approach can account for concept acquisition in a number of special cases in the sciences. He also argues for a particular view of applied mathematics, a view that supports Platonism against Naturalist alternatives. Not only does this engaging book present the Platonist-Natural

20. Origen and the Platonic Tradition

Directory of Open Access Journals (Sweden)

Ilaria L.E. Ramelli

2017-02-01

Full Text Available This study situates Origen of Alexandria within the Platonic tradition, presenting Origenas a Christian philosopher who taught and studied philosophy, of which theology was part and parcel. More speciﬁcally, Origen can be described as a Christian Platonist. He criticized “false philosophies” as well as “heresies,” but not the philosophy of Plato. Against the background of recent scholarly debates, the thorny issue of the possible identity between Origen the Christian Platonist and Origen the Neoplatonist is partially addressed (although it requires a much more extensive discussion; it is also discussed in the light of Origen’s formation at Ammonius’s school and the reception of his works and ideas in “pagan” Platonism. As a consequence, and against scholarly perspectives that tend to see Christianity as anti-Platonism, the ﬁnal section of this paper asks the question of what is imperial and late antique Platonism and, on the basis of rich evidence ,suggests that this was not only “pagan” institutional Platonism.

1. Platonic wholes and quantum ontology

CERN Document Server

Woszczek, Marek

2015-01-01

The subject of the book is a reconsideration of the internalistic model of composition of the Platonic type, more radical than traditional, post-Aristotelian externalistic compositionism, and its application in the field of the ontology of quantum theory. At the centre of quantum ontology is nonseparability. Quantum wholes are atemporal wholes governed by internalistic logic and they are primitive, global physical entities, requiring an extreme relativization of the fundamental notions of mechanics. That ensures quantum theory to be fully consistent with the relativistic causal structure, with

12. Self-Assembly of Calix[4]arene-Based Amphiphiles Bearing Polyethylene Glycols: Another Example of "Platonic Micelles".

Science.gov (United States)

Yoshida, Kenta; Fujii, Shota; Takahashi, Rintaro; Matsumoto, Sakiko; Sakurai, Kazuo

2017-09-12

The aggregation number of classical micelles exhibits a certain distribution, which is a recognizable feature of conventional micelles. However, we recently identified perfectly monodisperse calix[4]arene-based micelles whose aggregation numbers agree with the vertex numbers of regular polyhedra, that is, Platonic solids, and thus they are named "Platonic micelles". Regarding our hypothesis of the formation mechanism of Platonic micelles, both repulsive interactions including steric hindrance and electrostatic repulsions among the headgroups are important for determining their aggregation number; however, neither of these is necessarily needed to consider. In this study, we employed polyethylene glycols (PEGs) as the nonionic headgroup of calix[4]arene-based amphiphiles to study the effects of only repulsive interactions caused by steric hindrance on the formation of Platonic micelles. The amphiphiles containing relatively low-molecular-weight PEGs (550 or 1000 g mol -1 ) form dodecamer or octamer micelles, respectively, with no variation in the aggregation number. However, relatively high-molecular-weight PEGs (2000 g mol -1 ) produce polydispersed micelles with a range of aggregation number. PEG 2000 exhibits a greater affinity for water than PEG 550 and 1000, resulting in fewer hydrophobic interactions in micelle formation, as indicated by the drastic increase of the critical micelle concentration (CMC) value in the PEG 2000 system. The instability of the structure of PEG 2k CaL5 micelles might contribute to the higher mobility of PEG in the micellar shell, resulting in a non-Platonic aggregation number with polydispersity.

13. L'idea di giustizia in Platone

Directory of Open Access Journals (Sweden)

Fabio Bentivoglio

2014-03-01

Full Text Available The idea of justice is the center of gravity of Plato’s philosophy. To define the concept of justice also means defining the necessary and universal human condition that society must honor to keep in balance. The paper proposes a reconstruction of the route of Platonic thought that only in the Dialogues of maturity – particularly in the Parmenides – takes the accomplished philosophical form, that is, the logical-dialectical form. Finally, the paper would like to point out whether the outcome of Platonic reflection about the idea of the Good and Justice may still be relevant in order to interpret the “core” of the epochal crisis of the contemporary world.

15. Application of Phase Shifting Projection Moire on Solid Regular Figures and Plant Organs Three Dimensional Digital Model Generation

Science.gov (United States)

Lino, A. C. L.; Dal Fabbro, I. M.

2008-04-01

The conception of a tridimensional digital model of solid figures and plant organs started from topographic survey of virtual surfaces [1], followed by topographic survey of solid figures [2], fruit surface survey [3] and finally the generation of a 3D digital model [4] as presented by [1]. In this research work, i.e. step number [4] tested objects included cylinders, cubes, spheres and fruits. A Ronchi grid named G1 was generated in a PC, from which other grids referred as G2, G3, and G4 were set out of phase by 1/4, 1/2 and 3/4 of period from G1. Grid G1 was then projected onto the samples surface. Projected grid was named Gd. The difference between Gd and G1 followed by filtration generated de moiré fringes M1 and so on, obtaining the fringes M2, M3 and M4 from Gd. Fringes are out of phase one from each other by 1/4 of period, which were processed by the Rising Sun Moiré software to produce packed phase and further on, the unpacked fringes. Tested object was placed on a goniometer and rotate to generate four surfaces topography. These four surveyed surfaces were assembled by means of a SCILAB software, obtaining a three column matrix, corresponding to the object coordinates xi, also having elevation values and coordinates corrected as well. The work includes conclusions on the reliability of the proposed method as well as the setup simplicity and of low cost.

16. Experimental evaluation of the omnidirectional behavior of platonic polyhedron loudspeakers

Science.gov (United States)

Rollins, Sarah; Leishman, Timothy; Dix, Gordon

2003-10-01

Many architectural acoustics measurements require the use of an omnidirectional source. For several years, the source predominantly used for such applications has been the dodecahedron loudspeaker with small in-phase drivers mounted in each face. While other platonic polyhedron loudspeakers (PPLs) have not been used as frequently, they also produce nearly omnidirectional fields over limited bandwidths. Above cutoff frequencies specific to their geometries, all PPLs depart from ideal omnidirectional behavior, with varying degrees of directivity. While these cutoff frequencies are typically higher for higher-order polyhedra, they commonly fall within the bandwidths of standard measurements. The five types of PPLs have been constructed and measured to gain greater insight into their omnidirectional behaviors. Their frequency responses were taken at 2664 points over a sphere (5-deg polar and azimuthal angle increments) in an anechoic chamber. The measurements were then processed to produce directivity balloon plots. However, to better compare directivities and find the source consistently producing the most omnidirectional field over a useful bandwidth, a frequency-dependent standard deviation formula was implemented. Average values of the standard deviation parameter produce figures of merit that further characterize omnidirectionality. [Research supported by funding from the NSF REU program.

8. High figure of merit and thermoelectric properties of Bi-doped Mg2Si0.4Sn0.6 solid solutions

International Nuclear Information System (INIS)

Liu, Wei; Zhang, Qiang; Yin, Kang; Chi, Hang; Zhou, Xiaoyuan; Tang, Xinfeng; Uher, Ctirad

2013-01-01

The study of Mg 2 Si 1−x Sn x -based thermoelectric materials has received widespread attention due to a potentially high thermoelectric performance, abundant raw materials, relatively low cost of modules, and non-toxic character of compounds. In this research, Mg 2.16 (Si 0.4 Sn 0.6 ) 1−y Bi y solid solutions with the nominal Bi content of 0≤y≤0.03 are prepared using a two-step solid state reaction followed by spark plasma sintering consolidation. Within this range of Bi concentrations, no evidence of second phase segregation was found. Bi is confirmed to occupy the Si/Sn sites in the crystal lattice and behaves as an efficient n-type dopant in Mg 2 Si 0.4 Sn 0.6 . Similar to the effect of Sb, Bi doping greatly increases the electron density and the power factor, and reduces the lattice thermal conductivity of Mg 2.16 Si 0.4 Sn 0.6 solid solutions. Overall, the thermoelectric figure of merit of Bi-doped Mg 2.16 Si 0.4 Sn 0.6 solid solutions is improved by about 10% in comparison to values obtained with Sb-doped materials of comparable dopant content. This improvement comes chiefly from a marginally higher Seebeck coefficient of Bi-doped solid solutions. The highest ZT∼1.4 is achieved for the y=0.03 composition at 800 K. - Graphical abstract: (a)The relationship between electrical conductivity and power factor for Sb/Bi-doped Mg 2.16 (Si 0.4 Sn 0.6 ) 1−y (Sb/Bi) y (0 2.16 (Si 0.4 Sn 0.6 ) 1−y Bi y (0≤y≤0.03) solid solutions. (c)Temperature dependent dimensionless figure of merit ZT of Mg 2.16 (Si 0.4 Sn 0.6 ) 1−y Bi y (0≤y≤0.03) solid solutions. - Highlights: • Bi doped Mg 2.16 Si 0.4 Sn 0.6 showed 15% enhancement in the power factor as compared to Sb doped samples. • Bi doping reduced κ ph of Mg 2.16 Si 0.4 Sn 0.6 due to stronger point defect scattering. • The highest ZT=1.4 at 800 K was achieved for Mg 2.16 (Si 0.4 Sn 0.6 ) 0.97 Bi 0.03

In the fi rst section, he explores the origins of this doctrine in Plato’s dialogue «Sophistes» as well as in the twelfth book of Aristotle’s «Metaphysics». This idea is also apparent in the doctrine concerning the distinct levels of being and the faculties of the human soul, a concept common to various Greek philosophical schools. The larger section of the article provides a reconstruction of the basic features and the elements of this theory of the «intelligible Triad» in the Neo-Platonic philosophy of Plotinus, Porphyry, Iamblichus, Syrianus, and Proclus, as well as in the diff erent Gnostic schools. Finally, the author raises the question of how this concept was employed and transformed by the Church Fathers. This will be the topic of the section of the article to follow.

IDEA AND INTUITION On the Perceptibility of the Platonic Ideas in the Thought of Arthur Schopenhauer In this work, I examine the perceptibility of the Platonic Ideas in the thought of Arthur Schopenhauer. The work is divided into four chapters, each focusing and building upon a specific aspect related to this questi on. The first chapter (Plato and the Primacy of Intellect) deals with Scho penhauers interpretation specific to Platonic thought. I there address the question of why it is tha...

13. THE INTELLIGIBLE TRIADIN NEO-PLATONISM AND PATRISTICS

A. FOKIN

2011-12-01

Full Text Available n this second part of his paper the author concerns with the question about in what way from the fourth century A. D. onward the theory of so-called «intelligible triad» (esse, vivere, intellegere was borrowed from Neo-Platonic philosophy by some Christian theologians. This triad was mostly used to construct Christian trinitarian doctrine and to prove the consubstantiality, as well as the unity and diversity between three persons of the Holy Trinity. This theory was also used to demonstrate the existence of God as the unique Source of all being, life and intellect presented in the created order of beings, which gradually partake in these three Divine perfections. The «intelligible triad» also had an impact on the Patristic psychology, especially on the theory of self-conscientiousness and of the structure of human soul and of the universe.

14. Platonism and Akrasia in Chrysippus. The Interpretation of Marcelo Boeri

Directory of Open Access Journals (Sweden)

Ricardo Salles

2010-12-01

Full Text Available The paper addresses two questions regarding the interpretation of akrasia among the Stoics, offered by Marcelo Boeri in his book Appearance and Reality in Greek Thought: On the one hand, can Chrysippus’s monistic adaptation of the Platonic model of the divided soul set forth in Book iv of the Republic provide a philosophically satisfactory explanation of the classical phenomenon of akrasia? On the other hand, is this phenomenon the true explanandum of this adaptation? The paper shows that the answer to both these questions could be negative and thus different from the answer provided by Boeri in his book. The argument is based on the analysis of Plutarch vm 446f-447b and on the analysis of the classical problem of akrasia.

Full Text Available The author argues that the Platonism that Plotinus inherits – setting aside Ammonius Saccas, of whom we know all too little – is by the later second century distinctly dualist in tendency, and is able, especially in the case of Plutarch, to quote Plato to its purpose. Plato himself, though, as the author maintains, is, despite appearances to the contrary, what one might term a ‘modified monist’. That is to say, he fully recognizes the degree of imperfection and evil in the world, and holds it to be ineradicable, but he does not in the last resort believe in a positive countervailing force to the Good or the One. What we have is simply a negative force, whether Indefinite Dyad, disorderly World-Soul, or Receptacle, which is an inevitable condition of their being a world at all, but which, as a side-effect of introducing diversity, generates various sorts of imperfection. It is this scenario that justifies his follower Hermodorus in declaring that Plato recognizes only a single first principle, and it to this sort of monism – if anything, in a more pronounced form – that Plotinus returns.

19. The role of surface ligands in determining the electronic properties of quantum dot solids and their impact on photovoltaic figure of merits.

2018-01-18

Surface chemistry plays a crucial role in determining the electronic properties of quantum dot solids and may well be the key to mitigate loss processes involved in quantum dot solar cells. Surface ligands help to maintain the shape and size of the individual dots in solid films, to preserve the clean energy band gap of the individual particles and to control charge carrier conduction across solid films, in turn regulating their performance in photovoltaic applications. In this report, we show that the changes in size, shape and functional groups of small chain organic ligands enable us to modulate mobility, dielectric constant and carrier doping density of lead sulfide quantum dot solids. Furthermore, we correlate these results with performance, stability and recombination processes in the respective photovoltaic devices. Our results highlight the critical role of surface chemistry in the electronic properties of quantum dots. The role of the size, functionality and the surface coverage of the ligands in determining charge transport properties and the stability of quantum dot solids have been discussed. Our findings, when applied in designing new ligands with higher mobility and improved passivation of quantum dot solids, can have important implications for the development of high-performance quantum dot solar cells.

7. Organization of the concepts of the Platonic dialogue Parmenides into a software ontology

Science.gov (United States)

Dendrinos, Markos

2015-02-01

This paper concerns with the creation of a knowledge management ontology (in the open source OWL/ Protégé environment), including all the concepts and both the explicit and impicit relations between the concepts met in the Platonic dialogue Parmenides. The selected part of Parmenides is the second half (137c4-166c6), where Parmenides undertakes to take on the challenge of exposing a Zenonian type argumentation concerning the properties of one and being. The incorporation of the Platonic concepts and relations to a software ontology gives the opportunity to organize the philosophical ideas of a certain context in an hierarchical tree enriched with the various defined relations, detect possible logical inconsistencies and produce automatically further concept relations.

2. Queen Christina’s esoteric interests as a background to her Platonic Academies

Directory of Open Access Journals (Sweden)

Susanna Åkerman

2008-01-01

Full Text Available In 1681 the blind quietist, Francois Malaval, stated that Queen Christina of Sweden late in life had ‘given up’ [Hermes] Trismegistos and the Platonists, in favour of the Church fathers. The statement does not explain what role the Church fathers were to play in her last years, but it does show that Christina really had been interested in the rather elitist and esoteric doctrine of Hermetic Platonic Christianity. In this article the author looks at her library to show the depth of this Hermetic involvement. Her interest serves as a background to her life as ex-queen in Italy after her famous abdication from the Swedish throne in 1654, when she was 27 years old.

This paper considers the general multiple load structural topology design problems in the framework of the PLATO-N project. The problems involve a large number of discrete design variables and were modeled as a non-convex mixed 0–1 program. For the class of problems considered, a global...... optimization method based on the branch-and-cut concept was developed and implemented. In the method a large number of continuous relaxations were solved. We also present an algorithm for generating cuts to strengthen the quality of the relaxations. Several heuristics were also investigated to obtain efficient...... algorithms. The branch and cut method is used to solve benchmark examples which can be used to validate other methods and heuristics....

10. Automatic figure ranking and user interfacing for intelligent figure search.

Directory of Open Access Journals (Sweden)

Hong Yu

2010-10-01

Full Text Available Figures are important experimental results that are typically reported in full-text bioscience articles. Bioscience researchers need to access figures to validate research facts and to formulate or to test novel research hypotheses. On the other hand, the sheer volume of bioscience literature has made it difficult to access figures. Therefore, we are developing an intelligent figure search engine (http://figuresearch.askhermes.org. Existing research in figure search treats each figure equally, but we introduce a novel concept of "figure ranking": figures appearing in a full-text biomedical article can be ranked by their contribution to the knowledge discovery.We empirically validated the hypothesis of figure ranking with over 100 bioscience researchers, and then developed unsupervised natural language processing (NLP approaches to automatically rank figures. Evaluating on a collection of 202 full-text articles in which authors have ranked the figures based on importance, our best system achieved a weighted error rate of 0.2, which is significantly better than several other baseline systems we explored. We further explored a user interfacing application in which we built novel user interfaces (UIs incorporating figure ranking, allowing bioscience researchers to efficiently access important figures. Our evaluation results show that 92% of the bioscience researchers prefer as the top two choices the user interfaces in which the most important figures are enlarged. With our automatic figure ranking NLP system, bioscience researchers preferred the UIs in which the most important figures were predicted by our NLP system than the UIs in which the most important figures were randomly assigned. In addition, our results show that there was no statistical difference in bioscience researchers' preference in the UIs generated by automatic figure ranking and UIs by human ranking annotation.The evaluation results conclude that automatic figure ranking and user

In the words of the UK government chief scientific adviser "Science is not finished until it's communicated" (Walport 2013). The tools to produce good visual communication have never been so easily accessible to scientists as at the present. Correspondingly, it has never been easier to produce and disseminate poor graphics. In this presentation, we highlight some good practice and offer some practical advice in preparing scientific figures for presentation to peers or to the public. We identify common mistakes in visualisation, including some made by the authors, and offer some good reasons not to trust defaults in graphics software. In particular, we discuss the use of colour scales and share our experiences in running a social media campaign (http://tiny.cc/endrainbow) to replace the "rainbow" (also "jet", or "spectral") colour scale as the default in (climate) scientific visualisation.

Neste Corporation's net sales during 1991 totalled USD 12.6 billion, an increase of 11 % over the figure for 1990. The largest growth in net sales took place in Neste Oil's trading activities and sales of in-house-produced crude oil. In the chemicals sector. particular growth was recorded in resins production. Gas, Shipping and Exploration and Production performed slightly better than during 1990. Oil's performance remained satisfactory. The performance of Chemicals, however, fell back considerably, primarily, as a result of the worldwide drop in prices in the petrochemicals and plastics industries. As a result, the Corporation's overall result was substantially below the good level recorded in 1990. The Corporation's operating margin totalled USD 650 million

De la sensation commune à la compréhension scientifique, nos idées sur la nature et les propriétés de la lumière ont connu un long cheminement depuis les théories de Platon jusqu'à la maîtrise du photon. L'Antiquité, la civilisation arabo-islamique, la Renaissance européenne et sa révolution scientifique, puis la science classique du me siècle, les avancées modernes enfin, autant de moments dans la riche histoire de nos connaissances sur la lumière. Ce livre décrit l'élaboration tourmentée des idées, tant philosophiques que scientifiques, qui ont scandé cette histoire, tirant profit des succès comme des échecs, des efforts comme des renoncements. "En regardant d'un oeil critique l'histoire de la lumière, nous pourrons accéder à notre tour à cette logique savoureuse et amère que l'on appelle Science." La première édition de ce livre, ici considérablement augmentée, a obtenu le prix Jean-Rostand du meilleur ouvrage de vulgarisation scientifique.

16. KIAI: FIGUR ELITE PESANTREN

Full Text Available In a pesantren (Islamic boarding school, kiai is an strategic element. Javanese kiai mainly believe that a pesantren is a small palace where he becomes the ultimate source of power and authority. Even though he lives in a rural village, he becomes a member of elite group in social, politic and economic sides in the society. Kiai who leads big pesantren has successfully enlarged their power in term of nation so kiai could be accepted in national elite. The position of kiai is higher among all pesantren elements. The degree as an Islamic scholar is exactly a sacred degree in pesantren culture and tradition. Without his figure, it is impossible for a pesantren to develop and survive. Kiai holds an ultimate position on educate the behavior and morality of the santri (students to be qualified and compatible Muslims generation. Kiai is not only a leader but he is also the man behind the leadership itself in supporting the progress of Islamic education institution for Muslims generations.

Full Text Available The chapters dedicated to Parmenides and Plato play a decisive role in the composition strategy of the Adversus Colotem, since this is where Plutarch most clearly defines the background dualist thesis that will help demonstrate that Platonism is superior to Epicurism. By showing Parmenides too as a dualist engaged in distinguishing between the sensible and the intelligible world, Plutarch structures a history of ancient philosophy entirely focused on Plato. These chapters also bear witness of another centre of interest, namely Aristoteles (§ 14, who, despite the criticism he aimed at the theory of ideas, is not completely refuted, but rather used as a possible ally against epicurean materialists, Plutarch’s true bête noire.Les chapitres consacrés à Parménide et Platon jouent un rôle décisif dans la stratégie de composition de l’Adversus Colotem : c’est là en effet que Plutarque définit de la manière la plus claire la thèse dualiste de fond qui va servir à démontrer la supériorité du platonisme sur l’épicurisme. En présentant Parménide lui aussi comme un dualiste occupé à distinguer entre monde sensible et monde intelligible, Plutarque articule une histoire de la philosophie antique entièrement centrée sur Platon. Les chapitres témoignent ensuite d’un autre centre d’intérêt, avec la mention d’Aristote (§ 14, lequel, malgré les critiques qu’il adresse à la théorie des idées, n’est pas complètement réfuté, mais plutôt utilisé comme un allié possible contre les matérialistes épicuriens, la véritable « bête noire » de Plutarque.I capitoli dedicati a Parmenide e Platone giocano un ruolo decisivo nella strategia compositiva dell’Adversus Colotem: è qui infatti che Plutarco delinea nel modo più chiaro la tesi dualistica di fondo che servirà a dimostrare la superiorità del platonismo sull’epicureismo.

Full Text Available This article refers to some of the findings of a research project implemented as a teaching strategy to generate environments for the learning of platonic and archimedean solids, with a group of eighth grade students. This strategy was based on the meaningful learning approach and on the use of representation systems using the ontosemiotic approach in mathematical education, as a framework for the construction of mathematical concepts. This geometry teaching strategy adopts the stages of exploration, representation-modeling, formal construction and study of applications. It uses concrete, physical and tangible materials for origami, die making, and structures for the construction of threedimensional solids considered external tangible solid representation systems, as well as computer based educational tools to design dynamic geometry environments as intangible external representation systems.These strategies support both the imagination and internal systems of representation, fundamental to the comprehension of geometry concepts.

19. Evaluation of the pole figure

1984-01-01

In the present work it's shown the possibility of obtaining a pole-figure from the data generated in a conventional X-ray equipment, with a commercial goniometer and no electronic device to process the data. The way to plot the pole-figure on-line is by means of measuring the diffractogram and plot manually the stereographic projections. The atainable precision is very low in such a cumbersome process. In this paper we substitute such method by storing the data in a punched tape from a conventional teletype. The data is processed in a computer and the pole-figure is recorded by a plotter attached to the computer. (author)

The consumption of final energy in France in 2006 increased slightly on the whole (+0.6%) and in all sectors except the industry (-0.7%). The final energy consumption is defined as the difference between the total consumption of primary energy and the consumption of the energy production sector. The evolution of the consumption of final energy is different according to the type of energy: +4.1% for coal (due to the strong demand in the iron and steel industry), +3.6% for renewable energies (due to specific development programs), +1.5% for electrical power and no change for oil and natural gas. Despite high prices, sales of car fuels rose by 0.4%, this figure hides the fact that the sales of fuels for diesel cars rose by 2.7% (because of the growing population of diesel cars) while those of grade petrol kept on plummeting (-5.9%). It is important to note that the releases of CO 2 due to energy went down by -1.4% in 2006. The energy bill increased by +18.5% to fetch 46.2*10 9 euros despite the decrease of the imported volumes. This articles details the energy figures for France in 2006 and sheds light particularly on 3 aspects: first, the annual trends in energy since 1973, secondly, the energy bill and thirdly the figures for electricity, natural gas, solid mineral fuels, hydrocarbons and renewable sources of energy.

11. Platon G. Kostyuk (August 20, 1924-May 10, 2010): A unique survey of a life spanning turbulent times.

2012-01-01

On May 10th 2010 Platon Grigorevitch Kostyuk sadly left us at the age of 85. He was a talented scientist, a brilliant experimenter, an outstanding organizer of science and an excellent teacher. Platon Kostyuk was born in 1924 in Kiev, Ukraine. He obtained a double education: a graduate of the Kiev University Department of Biology in 1946 and the Kiev Medical Institute in 1949, he became a pioneer in neuroscience, the first in the Soviet Union to use microelectrodes for intracellular recording of electrical signals in neurons. Despite the difficulties for international travel for those living behind the Iron Curtain, he was able to present his work at the International Congress of Physiology in Buenos Aires in 1959 and here met Prof. John Eccles who invited him to work at the University of Canberra in Australia in 1960–1961. This was the start of an outstanding international career, complementing his creative achievements in the Soviet Union. In 1966 P.G. Kostyuk became director of the Bogomoletz Institute of Physiology in Kiev, which he headed for nearly 45 years. Under his direction this Institute became a leading centre for neuroscience, renowned not only in the Soviet Union but also internationally. New directions of research were developed in cell physiology, molecular biophysics and neurophysiology. Several important discoveries were made including the development of a method for intracellular perfusion, evidence for a calcium-dependent conductance in nerve cells and the discovery of new types of ion channels. Elected to the Ukraine Academy of Science in 1969 and Grand Academician of the Soviet Academy of Science in 1974, Kostyuk has also been honoured by many international societies. He is the author of more than 650 articles, 17 monographs and 7 discoveries and was the creator and editor of two scientific journals: "Neurophysiology" and "Neuroscience". The outstanding career and multifaceted activities of Academician Platon Kostyuk form a pyramid of

Full Text Available The questions as to whether the cosmic order of this world is based on action/agent or not? And if an agent is involved and the world and what it contains have to be seen as action, could we declare the cosmic order a providential order? are among the problems which have always occupied the mind of philosophers.      Reading through Platonic corpse leads us to the conclusion that he has founded his metaphysics upon the very idea of world of ideas. According to his works and words, Plato is a proponent of the theory of ideas. As a matter of fact, Plato's metaphysics lies in the theory of ideas. Plato illustrates the general makeup of the world of ideas and the way sensible objects stand in relation with the beings dwelling in the latter world by the well-known cave allegory in the seventh book of Republic. In his view, whatever we find around ourselves not only are not authentic realities but rather they are merely shadows of the truth. Every phenomenon has an essence or reality which is known as its form. The idea of Good overshadows the other ideas insofar as these latter ideas or forms are seen as the effects of the former. It seems we can take God, the One, Absolute Good, Absolute Beauty and Good in itself as expressions of the same reality which Plato has used in different contexts through his works. Along these terms some other notions have also been brought up like intellect, divine intellect, Demiurge, ideas and the particulars of material world.

3. Hooke's figurations: a figural drawing attributed to Robert Hooke.

Science.gov (United States)

Hunter, Matthew C

2010-09-20

The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

4. Proclus' Elaboration of Platonic Remarks on the Problem of Evils, and their Relation to Divine Providence and Efficiency

Directory of Open Access Journals (Sweden)

Reza korrang beheshti

2014-06-01

Full Text Available Although there is not a fully developed theory of evil in Plato, some various remarks are interspersed throughout his dialogues which provided the main materials for subsequent Platonists to elaborate a systematic doctrine of evil. Proclus is the most distinguished philosopher of the later Neoplatonism whose view became authoritative within the School and thus is most representative of the Neoplatonic doctrine of evil. By a critical assessment of the antecedent theories of evil, Proclus attempts to give a monistic interpretation of Platonic remarks on the problem of evil. According to his explanation, the higher degrees and principles of Being are only and purely good and are not the causes of evils but the good things for all things alone. Evils, however, exist necessarily but only among particular beings in a relative, parasitic, accidental way and dependent upon the good. The parasitic accidental existence of evil does not have a real efficient cause. It arises due to an asymmetry between the activities of the several faculties or powers of a complex particular being. Moreover, the existence of evil is so mixed with and dependent upon the good that despite its opposition to the good, contributes, in its own manner, to the fulfillment of goodness of the whole Universe, being thus reconcilable with Divine Providence and Efficiency.

5. Enhanced spatial resolution on figures versus grounds.

Hecht, Lauren N; Cosman, Joshua D; Vecera, Shaun P

2016-07-01

Much is known about the cues that determine figure-ground assignment, but less is known about the consequences of figure-ground assignment on later visual processing. Previous work has demonstrated that regions assigned figural status are subjectively more shape-like and salient than background regions. The increase in subjective salience of figural regions could be caused by a number of processes, one of which may be enhanced perceptual processing (e.g., an enhanced neural representation) of figures relative to grounds. We explored this hypothesis by having observers perform a perceptually demanding spatial resolution task in which targets appeared on either figure or ground regions. To rule out a purely attentional account of figural salience, observers discriminated targets on the basis of a region's color (red or green), which was equally likely to define the figure or the ground. The results of our experiments showed that targets appearing on figures were discriminated more accurately than those appearing in ground regions. In addition, targets appearing on figures were discriminated better than those presented in regions considered figurally neutral, but targets appearing within ground regions were discriminated more poorly than those appearing in figurally neutral regions. Taken together, our findings suggest that when two regions share a contour, regions assigned as figure are perceptually enhanced, whereas regions assigned as ground are perceptually suppressed.

This article analyses the ingredients of empire as a pattern of order with geopolitical effects. Noting the imperial form's proclivity for expansion from a critical reading of historical sociology, the article argues that the principal manifestation of earlier geopolitics lay not in the nation...... but in empire. That in turn has been driven by a view of the world as disorderly and open to the ordering will of empires (emanating, at the time of geopolitics' inception, from Europe). One implication is that empires are likely to figure in the geopolitical ordering of the globe at all times, in particular...... after all that has happened in the late twentieth century to undermine nationalism and the national state. Empire is indeed a probable, even for some an attractive form of regime for extending order over the disorder produced by globalisation. Geopolitics articulated in imperial expansion is likely...

9. Are figure legends sufficient? Evaluating the contribution of associated text to biomedical figure comprehension.

Biomedical scientists need to access figures to validate research facts and to formulate or to test novel research hypotheses. However, figures are difficult to comprehend without associated text (e.g., figure legend and other reference text). We are developing automated systems to extract the relevant explanatory information along with figures extracted from full text articles. Such systems could be very useful in improving figure retrieval and in reducing the workload of biomedical scientists, who otherwise have to retrieve and read the entire full-text journal article to determine which figures are relevant to their research. As a crucial step, we studied the importance of associated text in biomedical figure comprehension. Twenty subjects evaluated three figure-text combinations: figure+legend, figure+legend+title+abstract, and figure+full-text. Using a Likert scale, each subject scored each figure+text according to the extent to which the subject thought he/she understood the meaning of the figure and the confidence in providing the assigned score. Additionally, each subject entered a free text summary for each figure-text. We identified missing information using indicator words present within the text summaries. Both the Likert scores and the missing information were statistically analyzed for differences among the figure-text types. We also evaluated the quality of text summaries with the text-summarization evaluation method the ROUGE score. Our results showed statistically significant differences in figure comprehension when varying levels of text were provided. When the full-text article is not available, presenting just the figure+legend left biomedical researchers lacking 39-68% of the information about a figure as compared to having complete figure comprehension; adding the title and abstract improved the situation, but still left biomedical researchers missing 30% of the information. When the full-text article is available, figure comprehension

Full Text Available Figures are ubiquitous in biomedical full-text articles, and they represent important biomedical knowledge. However, the sheer volume of biomedical publications has made it necessary to develop computational approaches for accessing figures. Therefore, we are developing the Biomedical Figure Search engine (http://figuresearch.askHERMES.org to allow bioscientists to access figures efficiently. Since text frequently appears in figures, automatically extracting such text may assist the task of mining information from figures. Little research, however, has been conducted exploring text extraction from biomedical figures.We first evaluated an off-the-shelf Optical Character Recognition (OCR tool on its ability to extract text from figures appearing in biomedical full-text articles. We then developed a Figure Text Extraction Tool (FigTExT to improve the performance of the OCR tool for figure text extraction through the use of three innovative components: image preprocessing, character recognition, and text correction. We first developed image preprocessing to enhance image quality and to improve text localization. Then we adapted the off-the-shelf OCR tool on the improved text localization for character recognition. Finally, we developed and evaluated a novel text correction framework by taking advantage of figure-specific lexicons.The evaluation on 382 figures (9,643 figure texts in total randomly selected from PubMed Central full-text articles shows that FigTExT performed with 84% precision, 98% recall, and 90% F1-score for text localization and with 62.5% precision, 51.0% recall and 56.2% F1-score for figure text extraction. When limiting figure texts to those judged by domain experts to be important content, FigTExT performed with 87.3% precision, 68.8% recall, and 77% F1-score. FigTExT significantly improved the performance of the off-the-shelf OCR tool we used, which on its own performed with 36.6% precision, 19.3% recall, and 25.3% F1-score for

12/21/98, at America's Stonehenge, DMM detected, and drew, the full stick-figure equivalent of Canis Major, CM, as depicted by our Wolf Clan leaders, and many others. Profound, foundational physics is implied, since this occurred in the Watch House there, hours before the ``model rose.'' Similar configurations like Orion, Osiris of ancient Egypt, show that such figures are projected through solid parts of the Earth, as two-dimensional equivalents of the three-dimensional star constellations. Such ``sticks'' indicate that ``line equivalents'' connect the stars, and the physical mechanism projects outlines detectable by traditional cultures. We had discussed this ``flashlight'' effect, and recognized some of its implications. RDM states that the flashlight is a strong, distant neutrino source; the lines represent neutrinos longitudinally aligned in gravitational excitation, opaque, to earthbound, transient, transversely excited neutrinos. ``Sticks'' represent ``graviton'' detection. Neutrinos' longitudinal alignment accounts for the weakness of gravitational force.

12. The latest figures on uranium

Vance, R.

According to the latest figures on uranium, soon to be published by the NEA, uranium resources, production and demand are all on the rise. Exploration efforts have increased recently in line with the expected expansion of nuclear energy in the coming years. Total identified resources have grown and are now sufficient to cover 100 years of supply at 2008 rates of consumption. Costs of production have, however, also increased. This article is based on the latest edition of the 'Red Book', Uranium 2009: Resources, Production and Demand, which presents the results of the most recent biennial review of world uranium market fundamentals and a statistical profile of the world uranium industry as of 1 January 2009. It contains official data provided by OECD Nuclear Energy Agency (NEA) and International Atomic Energy Agency (IAEA) member countries on uranium exploration, resources, production and reactor-related requirements. Projections of nuclear generating capacity and reactor-related uranium requirements through 2035 are also provided as well as a discussion of long-term uranium supply and demand issues. Despite recent declines stemming from the global financial crisis, world demand for electricity is expected to continue to grow significantly over the next several decades to meet the needs of an increasing population and economic growth. The recognition by an increasing number of governments that nuclear power can produce competitively priced, base-load electricity that is essentially free of greenhouse gas emissions, coupled with the role that nuclear can play in enhancing security of energy supply, increases the prospects for growth in nuclear generating capacity, although the magnitude of that growth remains to be determined. Regardless of the role that nuclear energy ultimately plays in meeting rising electricity demand, the uranium resource base is more than adequate to meet projected requirements. Meeting even high-case requirements to 2035 would consume less

13. Figure-ground assignment in pigeons: evidence for a figural benefit.

Lazareva, Olga E; Castro, Leyre; Vecera, Shaun P; Wasserman, Edward A

2006-07-01

Four pigeons discriminated whether a target spot appeared on a colored figural shape or on a differently colored background by first pecking the target and then reporting its location: on the figure or the background. We recorded three dependent variables: target detection time, choice response time, and choice accuracy. The birds were faster to detect the target, to report its location, and to learn the correct response on figure trials than on background trials. Later tests suggested that the pigeons might have attended to the figural region as a whole rather than using local properties in performing the figure-background discrimination. The location of the figural region did not affect figure-ground assignment. Finally, when 4 other pigeons had to detect and peck the target without making a choice report, no figural advantage emerged in target detection time, suggesting that the birds' attention may not have been automatically summoned to the figural region.

Berini, Pierre

2006-12-01

Three figures of merit are proposed as quality measures for surface plasmon waveguides. They are defined as benefit-to-cost ratios where the benefit is confinement and the cost is attenuation. Three different ways of measuring confinement are considered, leading to three figures of merit. One of the figures of merit is connected to the quality factor. The figures of merit were then used to assess and compare the wavelength response of hree popular 1-D surface plasmon waveguides: the single metal-dielectric interface, the metal slab bounded by dielectric and the dielectric slab bounded by metal. Closed form expressions are given for the figures of merit of the single metal-dielectric interface.

Full Text Available In this study, we aim to investigate how students build interaction between concepts and figure in geometry. For this purpose we developed two type data collection tool. First one called shapely is formed eight open ended question which has concepts and figure. Second one called shapeless is formed eight open ended question which has only concepts. To prepare this data collection tools’ difficulty level we took two math teachers’ opinions. Developed data collection tools were applied 120 students at 9th grade and 11th grade in Trabzon Gazi Anatolian High School. First of all we applied shapeless questions. One month later we applied shapely questions. We investigated students’ answer and the data showed that students more succeed in shapely questions than shapeless questions. We concluded that the difficulty of solving shapeless question result from students didn’t manage to draw figure representing concept knowledge or draw wrong figure, figure drawn by students can’t fulfıl generalizability condition and students who have little knowledge of concept in geometry is under the influence of prototype figure.Key Words:    Figural concepts theory, geometrical reasoning, geometry teaching

4. Presenting Fake Figures: A Tool to Teach Effective Scientific Figure Design

Full Text Available As trained scientists, we become adept not only at analyzing and understanding figures in the scientific literature, but also at designing figures to effectively represent our own data and findings. As educators, we strive to pass on these skills to our students, some of whom will ultimately become scientists themselves. Conveying the principles of effective figure design can be challenging, particularly when students have had little exposure to the process of reading scientific literature, much less writing a piece of scientific literature. Improvisational activities in the classroom reinforce teaching goals such as spontaneity, risk-taking, creativity, communication skills, team-building, and critical thinking (2. Indeed, improv training for scientists is becoming more common, helping scientists to communicate more spontaneously about their work and connect with their audience (1. In this article, we present an improvisational game that can aid in the teaching of effective scientific figure design. This “Present-a-Fake-Figure Exercise” is applicable to both the classroom and laboratory settings. In this learning activity, students improvise presenting fake scientific figures to an audience of their peers. These fake figures are prepared beforehand by the instructor and exemplify the do’s and don’ts of scientific figure design. Some of the learning outcomes of the activity include (1 identifying what makes a scientific figure cohesive, easy to analyze, and reader-friendly, and (2 identifying strategies that are useful in the design of a multi-panel figure to convey a scientific story.

2016-05-01

This work explores the links between the concepts of "soul", "law" and "word" in Plato's work, in order to highlight the importance and the centrality of the philosophical-therapeutic dimension in the Greek philosopher's thought. In that way, this work pretends to show that "contemporary" problems usually discussed within "Human Sciences" in general, and Psychiatry in particular, should confront their knowledge with Plato's work, mainly due to the profound influence his ideas have had in our Greco-Christian culture. In that sense, and with that objective, this work also explores Michel Foucault's lucid and controversial interpretation of Plato.

9. Purely temporal figure-ground segregation.

Science.gov (United States)

Kandil, F I; Fahle, M

2001-05-01

Visual figure-ground segregation is achieved by exploiting differences in features such as luminance, colour, motion or presentation time between a figure and its surround. Here we determine the shortest delay times required for figure-ground segregation based on purely temporal features. Previous studies usually employed stimulus onset asynchronies between figure- and ground-containing possible artefacts based on apparent motion cues or on luminance differences. Our stimuli systematically avoid these artefacts by constantly showing 20 x 20 'colons' that flip by 90 degrees around their midpoints at constant time intervals. Colons constituting the background flip in-phase whereas those constituting the target flip with a phase delay. We tested the impact of frequency modulation and phase reduction on target detection. Younger subjects performed well above chance even at temporal delays as short as 13 ms, whilst older subjects required up to three times longer delays in some conditions. Figure-ground segregation can rely on purely temporal delays down to around 10 ms even in the absence of luminance and motion artefacts, indicating a temporal precision of cortical information processing almost an order of magnitude lower than the one required for some models of feature binding in the visual cortex [e.g. Singer, W. (1999), Curr. Opin. Neurobiol., 9, 189-194]. Hence, in our experiment, observers are unable to use temporal stimulus features with the precision required for these models.

10. Figuring process of potassium dihydrogen phosphate crystal using ion beam figuring technology.

2017-09-01

Currently, ion beam figuring (IBF) technology has presented many excellent performances in figuring potassium dihydrogen phosphate (KDP) crystals, such as it is a noncontact figuring process and it does not require polishing fluid. So, it is a very clean figuring process and does not introduce any impurities. However, the ion beam energy deposited on KDP crystal will heat the KDP crystal and may generate cracks on it. So, it is difficult directly using IBF technology to figure KDP crystal, as oblique incident IBF (OI-IBF) has lower heat deposition, higher removal rate, and smoother surface roughness compared to normal incident IBF. This paper studied the process of using OI-IBF to figure KDP crystal. Removal rates and removal functions at different incident angles were first investigated. Then heat depositions on a test work piece were obtained through experiments. To validate the figuring process, a KDP crystal with a size of 200  mm×200  mm×12  mm was figured by OI-IBF. After three iterations using the OI-IBF process, the surface error decreases from the initial values with PV 1.986λ RMS 0.438λ to PV 0.215λ RMS 0.035λ. Experimental results indicate that OI-IBF is feasible and effective to figure KDP crystals.

Ramachandran, V S; Anstis, S

1986-01-01

We explored the relationship between figure-ground segmentation and apparent motion. Results suggest that: static elements in the surround can eliminate apparent motion of a cluster of dots in the centre, but only if the cluster and surround have similar "grain" or texture; outlines that define occluding surfaces are taken into account by the motion mechanism; the brain uses a hierarchy of precedence rules in attributing motion to different segments of the visual scene. Being designated as "figure" confers a high rank in this scheme of priorities.

2017-11-10

The edge effect is regarded as one of the most difficult technical issues for fabricating large primary mirrors, as it can greatly reduce the key performance of the optical system. Ion beam figuring (IBF) has the advantage of no edge effect, so we can use it to remove high points on the edge and improve surface accuracy. The edge local correction method (ELCM) of IBF processes only the surface edge zone, and is very different from the current full caliber figuring method (FCFM). Therefore, it is necessary to study the ELCM of IBF. In this paper, the key factors of ELCM are analyzed, such as dwell time algorithm, edge data extension methods, and the outward dimension of the starting figuring point. At the same time, the distinctions between ELCM and FCFM are compared. Finally, a 142 mm diameter fused silica mirror is fabricated to verify the validity of the theoretical of ELCM. The experimental results indicate that the figuring precision and efficiency can be obviously improved by ELCM.

1. INFORMATIONAL MODEL OF MENTAL ROTATION OF FIGURES

Directory of Open Access Journals (Sweden)

V. A. Lyakhovetskiy

2016-01-01

Full Text Available Subject of Study.The subject of research is the information structure of objects internal representations and operations over them, used by man to solve the problem of mental rotation of figures. To analyze this informational structure we considered not only classical dependencies of the correct answers on the angle of rotation, but also the other dependencies obtained recently in cognitive psychology. Method.The language of technical computing Matlab R2010b was used for developing information model of the mental rotation of figures. Such model parameters as the number of bits in the internal representation, an error probability in a single bit, discrete rotation angle, comparison threshold, and the degree of difference during rotation can be changed. Main Results.The model reproduces qualitatively such psychological dependencies as the linear increase of time of correct answers and the number of errors on the angle of rotation for identical figures, "flat" dependence of the time of correct answers and the number of errors on the angle of rotation for mirror-like figures. The simulation results suggest that mental rotation is an iterative process of finding a match between the two figures, each step of which can lead to a significant distortion of the internal representation of the stored objects. Matching is carried out within the internal representations that have no high invariance to rotation angle. Practical Significance.The results may be useful for understanding the role of learning (including the learning with a teacher in the development of effective information representation and operations on them in artificial intelligence systems.

This book addresses the mathematical rationality contained in the making of string figures. It does so by using interdisciplinary methods borrowed from anthropology, mathematics, history and philosophy of mathematics. The practice of string figure-making has long been carried out in many societies, and particularly in those of oral tradition. It consists in applying a succession of operations to a string (knotted into a loop), mostly using the fingers and sometimes the feet, the wrists or the mouth. This succession of operations is intended to generate a final figure. The book explores differ

Full Text Available Figure skating is a physically demanding sport that requires a unique combination of artistic ability, speed, agility, flexibility and power. During the last decades not only the competitive schedule has become tougher, but after introduction of the new judging system in 2003, also more emphasis is put on difficult technical elements, jumps, steps and spins (ISU Rules, 2006. More studies about possible increasing prevalence of stress fractures in figure skaters and contributing factors are lacking (Dubravcic-Simunjak et al., 2003; Moran, 2000; Pecina et al., 1990. Therefore the aim of this study was to obtain data about the current stress fracture cumulative risk among elite junior and senior figure skaters, as well as possible factors that may contribute to stress fracture incidence. An anonymous questionnaire, divided into 5 sections, inquired about the prevalence of stress fracture were mailed and distributed to all 62 International Skating Union (ISU members by the ISU headquarters in Lausanne, Switzerland. The guidelines of the Helsinki declaration 2004 were followed. From the 644 skaters who received the questionnaire, 412 completed ones were returned from 110 female juniors (78 single skaters, 12 pair skaters and 20 ice dancers and 135 female seniors (97 single skaters, 16 pair skaters and 22 ice dancers and from 79 male juniors (47 single skaters, 12 pair skaters and 20 ice dancers and 88 male seniors (50 single skaters, 16 pair skaters and 22 ice dancers, coming from different ISU members. The response rate was 62% in females and 67% in males. The median age for female skaters was 16 years and for males 18 years (range 12-25 years. All participants started to skate between 3 and 6 years of age and started to compete in national and international competitions when they were between 5 and 7 years old.

It is very difficult to assess the cost of abandoning nuclear energy in France because a lot of relevant figures are not published. The Court of Auditors is due to publish in 2012 a report of the costs of nuclear energy. In the case of nuclear phase out 2 costs have to be considered the dismantling cost and the cost of processing wastes and their disposal. As for the dismantling cost, official assessments in Great-Britain or Germany give a figure around 3 billions pounds per dismantled unit. In France the law imposes to EDF to put by 18 billions euros by 2016 for the future reactor dismantling. Concerning the cost of wastes, it could reach 35 billions euros for dealing with all the radioactive wastes produced till 2030. (A.C.)

1989-08-01

Great improvement has been made in the past several years in the quality of optical components used in synchrotron radiation (SR) beamlines. Most of this progress has been the result of vastly improved metrology techniques and instrumentation permitting rapid and accurate measurement of the surface finish and figure on grazing incidence optics. A significant theoretical effort has linked the actual performance of components used as x-ray wavelengths to their topological properties as measured by surface profiling instruments. Next-generation advanced light sources will require optical components and systems to have sub-arc second surface figure tolerances. This paper will explore the consequences of these requirements in terms of manufacturing tolerances to see if the present manufacturing state-of-the-art is capable of producing the required surfaces. 15 refs., 14 figs., 2 tabs

Chapman; Henry N. , Taylor; John S.

2010-02-16

A process is provided for producing near-perfect optical surfaces, for EUV and soft-x-ray optics. The method involves polishing or otherwise figuring the multilayer coating that has been deposited on an optical substrate, in order to correct for errors in the figure of the substrate and coating. A method such as ion-beam milling is used to remove material from the multilayer coating by an amount that varies in a specified way across the substrate. The phase of the EUV light that is reflected from the multilayer will be affected by the amount of multilayer material removed, but this effect will be reduced by a factor of 1-n as compared with height variations of the substrate, where n is the average refractive index of the multilayer.

8. Figuration of tourist personality and tourist travels

Directory of Open Access Journals (Sweden)

Đorđević Saša

2013-01-01

Full Text Available Quality of tourist travel is a relative category, because its success depends on the subjective perception of the personality of tourists on a tourist trip. For this reason, any tourist trip can be treated from the perspective of different types of figurative forms of tourists' personality, which also determine different quality of tourist travel, which, in turn, makes them different. Thus, any tourist trip, unto itself, has its own uniqueness, taking on the forms and content created, for the most part, by the tourists themselves, along with all other tourism stakeholders involved in this process. These forms and contents are primarily conditioned by the spiritual profile of tourists' personality and their psychological and motivational preferences, which is symbolically represented in the figurative context of a chess game. In addition to this, identification of essential characteristics of different spiritual profiles of tourist's personality, must be a starting point for the programming of overall content and especially of animation and cultural content.

9. Variable-spot ion beam figuring

International Nuclear Information System (INIS)

Wu, Lixiang; Qiu, Keqiang; Fu, Shaojun

2016-01-01

This paper introduces a new scheme of ion beam figuring (IBF), or rather variable-spot IBF, which is conducted at a constant scanning velocity with variable-spot ion beam collimated by a variable diaphragm. It aims at improving the reachability and adaptation of the figuring process within the limits of machine dynamics by varying the ion beam spot size instead of the scanning velocity. In contrast to the dwell time algorithm in the conventional IBF, the variable-spot IBF adopts a new algorithm, which consists of the scan path programming and the trajectory optimization using pattern search. In this algorithm, instead of the dwell time, a new concept, integral etching time, is proposed to interpret the process of variable-spot IBF. We conducted simulations to verify its feasibility and practicality. The simulation results indicate the variable-spot IBF is a promising alternative to the conventional approach.

In a manner reminiscent of “auteur theory”, writers such as Neil Gaiman, Warren Ellis or Grant Morrison developed attractive author personas which they consistently displayed through interviews, letter columns or social media, but also, more importantly, by inserting their avatars within the comics they scripted. Upon closer examination, however, it becomes clear that their work in fact simultaneously asserts and destabilizes writerly authority, in a manner that is consistent with Linda Hutcheon’s view of postmodernity. By multiplying author figures and playfully disseminating authority, Vertigo authors question their own authorial control over the text, asserting instead the crucial role played by the reader.

The European (EU 25) wish to substitute solid biomass origin energy consumption (principally wood and wood waste, but also straw, crop harvest residues, vegetal and animal waste) for a part of that of fossil fuel origin (petrol, gas and coal) is beginning to pay off. 58,7 million tons oil equivalent (Mtoe) of solid biomass was produced in 2005, i.e. a 3.1 Mtoe increase with respect to 2004. Production of primary energy coming from direct combustion of renewable municipal solid waste in incineration plants should also be added on to this figure. The 0,2 Mtoe increase in this production with respect to 2004 brings valorization of this type of waste up to 5,3 Mtoe in 2005. (author)

14. Figures and First Years: An Analysis of Calculus Students' Use of Figures in Technical Reports

2017-07-01

Full Text Available This three-year study focused on first-year Calculus I students and their abilities to incorporate figures in technical reports. In each year, these calculus students wrote a technical report as part of the Polar Bear Module, an educational unit developed for use in partner courses in biology, computer science, mathematics, and physics as part of the Multidisciplinary Sustainability Education (MSE project at Ithaca College. In the first year of the project, students received basic technical report guidelines. In year two, the report guidelines changed to include explicit language on how to incorporate figures. In year three, a grading rubric was added to the materials provided to one of the two classes. In all three years, the students performed below expectations in their use of graphs in their reports. Reviews of the figures in the 78 technical reports written by the 106 students showed repeated deficiencies in the figures and how the students used them in the discussion sections and in evidence-based arguments. In year three the student’s quantitative literacy (QL skills were assessed using an extract from a QL assessment instrument published in Numeracy. The results indicated that the students could both read and interpret figures, suggesting that issues with QL were not the main contributor to student difficulty with written discussion about graphs. The study underscores the need that explicit instructional attention be given to developing student knowhow in the use of figures in technical reports.

Silicon lenses are widely used for infrared applications. Especially for portable devices the size and weight of the optical system are very important factors. The use of aspherical silicon lenses instead of spherical silicon lenses results in a significant reduction of weight and size. The manufacture of silicon lenses is more challenging than the manufacture of standard glass lenses. Typically conventional methods like diamond turning, grinding and polishing are used. However, due to the high hardness of silicon, diamond turning is very difficult and requires a lot of experience. To achieve surfaces of a high quality a polishing step is mandatory within the manufacturing process. Nevertheless, the required surface form accuracy cannot be achieved through the use of conventional polishing methods because of the unpredictable behavior of the polishing tools, which leads to an unstable removal rate. To overcome these disadvantages a method called Ion Beam Figuring can be used to manufacture silicon lenses with high surface form accuracies. The general advantage of the Ion Beam Figuring technology is a contactless polishing process without any aging effects of the tool. Due to this an excellent stability of the removal rate without any mechanical surface damage is achieved. The related physical process - called sputtering - can be applied to any material and is therefore also applicable to materials of high hardness like Silicon (SiC, WC). The process is realized through the commercially available ion beam figuring system IonScan 3D. During the process, the substrate is moved in front of a focused broad ion beam. The local milling rate is controlled via a modulated velocity profile, which is calculated specifically for each surface topology in order to mill the material at the associated positions to the target geometry. The authors will present aspherical silicon lenses with very high surface form accuracies compared to conventionally manufactured lenses.

18. Equilibrium figures for beta Lyrae type disks

International Nuclear Information System (INIS)

Wilson, R.E.

1981-01-01

Accumulated evidence for a geometrically and optically thick disk in the β Lyrae system has now established the disk's basic external configuration. Since the disk has been constant in its main properties over the historical interval of β Lyrae observations and also seems to have a basically well-defined photosphere, it is now time to being consideration of its sturcture. Here, we compute equilibrium figures for self-gravitating disks around stars in binary systems as a start toward eventual computation of complete disk models. A key role is played by centrifugally limited rotation of the central star, which would naturally arise late in the rapid phase of mass transfer. Beta Lyrae is thus postulated to be a double-contact binary, which makes possible nonarbitrary separation of star and disk into separate structures. The computed equilibrium figures are three-dimensional, as the gravitation of the second star is included. Under the approximation that the gravitational potential of the disk is that of a thin wire and that the local disk angular velocity is proportional to u/sup n/ (u = distance from rotation axis), we comptue the total potential and locate equipotential surfaces. The centrifugal potential is written in a particularly convenient form which permits one to change the rotation law discontinuously (for example, at the star-disk coupling point) while ensuring that centrifugal potential and centrifigual force are continuous functions of position. With such a one-parameter rotation law, one can find equilibrium disk figures with dimensions very similar to those found in β Lyrae, but considerations of internal consistency demand at least a two-parameter law

19. Noise figure of amplified dispersive Fourier transformation

International Nuclear Information System (INIS)

Goda, Keisuke; Jalali, Bahram

2010-01-01

Amplified dispersive Fourier transformation (ADFT) is a powerful tool for fast real-time spectroscopy as it overcomes the limitations of traditional optical spectrometers. ADFT maps the spectrum of an optical pulse into a temporal waveform using group-velocity dispersion and simultaneously amplifies it in the optical domain. It greatly simplifies spectroscopy by replacing the diffraction grating and detector array in the conventional spectrometer with a dispersive fiber and single-pixel photodetector, enabling ultrafast real-time spectroscopic measurements. Following our earlier work on the theory of ADFT, here we study the effect of noise on ADFT. We derive the noise figure of ADFT and discuss its dependence on various parameters.

The human figure drawings of a group of emotionally-disturbed boys were compared with those of a group of well-adjusted boys closely matched for chronological age and another for mental age. A comparison based on Koppitz's (1968) original emotional indicators and another, based on new UK norms, showed that the emotionally-disturbed children included significantly more indicators in their drawings than their well-adjusted peers. Although this difference was statistically significant it is actually quite small. In addition, there were no differences among the groups in the kinds of indicators they exhibited. The usefulness of the Koppitz test as a tool for clinical use is questioned.

4. Exogenous spatial attention influences figure-ground assignment.

Vecera, Shaun P; Flevaris, Anastasia V; Filapek, Joseph C

2004-01-01

In a hierarchical stage account of vision, figure-ground assignment is thought to be completed before the operation of focal spatial attention. Results of previous studies have supported this account by showing that unpredictive, exogenous spatial precues do not influence figure-ground assignment, although voluntary attention can influence figure-ground assignment. However, in these studies, attention was not summoned directly to a region in a figure-ground display. In three experiments, we addressed the relationship between figure-ground assignment and visuospatial attention. In Experiment 1, we replicated the finding that exogenous precues do not influence figure-ground assignment when they direct attention outside of a figure-ground stimulus. In Experiment 2, we demonstrated that exogenous attention can influence figure-ground assignment if it is directed to one of the regions in a figure-ground stimulus. In Experiment 3, we demonstrated that exogenous attention can influence figure-ground assignment in displays that contain a Gestalt figure-ground cue; this result suggests that figure-ground processes are not entirely completed prior to the operation of focal spatial attention. Exogenous spatial attention acts as a cue for figure-ground assignment and can affect the outcome of figure-ground processes.

To evaluate the current use of figures in Trial reports, and to make constructive suggestions for future practice. We surveyed all 77 reports of randomised controlled trials in five general medical journals during November 2006 to January 2007. The numbers and types of figures were determined, and then each Figure was assessed for its style, content, clarity and suitability. As a consequence, guidelines are developed for presenting figures, both in general and for each specific common type of Figure. Most trial reports contained one to three figures, mean 2.3 per article. The four main types were flow diagram, Kaplan Meier plot, Forest plot (for subgroup analyses) and repeated measures over time: these accounted for 92% of all figures published. For each type of figure there is a considerable diversity of practice in both style and content which we illustrate with selected examples of both good and bad practice. Some pointers on what to do, and what to avoid, are derived from our critical evaluation of these articles' use of figures. There is considerable scope for authors to improve their use of figures in clinical trial reports, as regards which figures to choose, their style of presentation and labelling, and their specific content. Particular improvements are needed for the four main types of figures commonly used.

7. Deficit in figure-ground segmentation following closed head injury.

Baylis, G C; Baylis, L L

1997-08-01

Patient CB showed a severe impairment in figure-ground segmentation following a closed head injury. Unlike normal subjects, CB was unable to parse smaller and brighter parts of stimuli as figure. Moreover, she did not show the normal effect that symmetrical regions are seen as figure, although she was able to make overt judgments of symmetry. Since she was able to attend normally to isolated objects, CB demonstrates a dissociation between figure ground segmentation and subsequent processes of attention. Despite her severe impairment in figure-ground segmentation, CB showed normal 'parallel' single feature visual search. This suggests that figure-ground segmentation is dissociable from 'preattentive' processes such as visual search.

Full Text Available Microgenetic analysis was used to investigate perception of illusory contour figures which represent whole, completed forms on the basis of segmented, incomplete stimulation. The analysis provided an experimental approach to this phenomenon which was standardly investigated phenomenologically. Experimental procedure consisted of two phases: a priming phase and b test phase which consisted of visual search task. Two types of visual search tasks were applied: (i classic detection, in which subjects were detecting presence or absence of the target stimuli and (ii two-alternative forced choice, 2AFC, in which subjects performed discrimination between two concurrent targets (target A vs. target B. Variation of exposition of prim stimuli was used as an indication of the percept formation period. Concepts like early vision, visual attention and feature binding were investigated. Four experiments were conducted. Their outcome showed that (i perception of amodal figure requires visual attention, (ii features binding precedes spatial attention and (iii time period of percept formation is dependent of task properties and varies between 50 - 150 ms. Some results obtained in this research could be explained by feature-integration theory (Treisman & Gelade, 1980; Treisman, 1986. Furthermore, percept formation period data comply with data acquired in Elliott & Müller's psychophysical research (1998.

10. Figure-ground mechanisms provide structure for selective attention.

Qiu, Fangtu T; Sugihara, Tadashi; von der Heydt, Rüdiger

2007-11-01

Attention depends on figure-ground organization: figures draw attention, whereas shapes of the ground tend to be ignored. Recent research has revealed mechanisms for figure-ground organization in the visual cortex, but how these mechanisms relate to the attention process remains unclear. Here we show that the influences of figure-ground organization and volitional (top-down) attention converge in single neurons of area V2 in Macaca mulatta. Although we found assignment of border ownership for attended and for ignored figures, attentional modulation was stronger when the attended figure was located on the neuron's preferred side of border ownership. When the border between two overlapping figures was placed in the receptive field, responses depended on the side of attention, and enhancement was generally found on the neuron's preferred side of border ownership. This correlation suggests that the neural network that creates figure-ground organization also provides the interface for the top-down selection process.

Qualified statistical data belong to the instruments of effective association work. Therefore the association, among other activities, carries out statistical investigations on business management among its member enterprises at intervals of two years. This volume contains the results of the business years 1976 and 1977. A main purpose of this statistics is to offer guidelines to the member enterprises, especially figures which allow to compare the evaluated average values of the business with data of the own enterprise, which may be, if necessary, an impetus to think about measures of rationalization. As in former statistics all the results are classified in seven categories that are determined by the size of the enterprise. Compared with the last questionnaire some items have been altered to facilitate the completion. Questions concerning the extent of the public utilities, the structure of the network system and investment planning have been introduced for the first time.

Sevaston, G.; Redding, D.; Lau, K.; Breckenridge, W.; Levine, B.; Nerheim, N.; Sirlin, S.; Kadogawa, H.

1991-01-01

A system concept for a space based segmented reflector telescope figure control subsystem is described. The concept employs a two phase architecture in which figure initialization and figure maintenance are independent functions. Figure initialization is accomplished by image sharpening using natural reference targets. Figure maintenance is performed by monitoring the relative positions and alignments of the telescope components using an optical truss. Actuation is achieved using precision positioners. Computer simulation results of figure initialization by pairwise segment coalignment/cophasing and simulated annealing are presented along with figure maintenance results using a wavefront error regulation algorithm. Both functions are shown to perform at acceptable levels for the class of submillimeter telescopes that are serving as the focus of this technology development effort. Component breadboard work as well as plans for a system testbed are discussed.

19. A figure control sensor for the Large Deployable Reflector (LDR)

Science.gov (United States)

Bartman, R.; Dubovitsky, S.

1988-01-01

A sensing and control system is required to maintain high optical figure quality in a segmented reflector. Upon detecting a deviation of the segmented surface from its ideal form, the system drives segment mounted actuators to realign the individual segments and thereby return the surface to its intended figure. When the reflector is in use, a set of figure sensors will determine positions of a number of points on the back surface of each of the reflector's segments, each sensor being assigned to a single point. By measuring the positional deviations of these points from previously established nominal values, the figure sensors provide the control system with the information required to maintain the reflector's optical figure. The optical lever, multiple wavelength interferometer, and electronic capacitive sensor, the most promising technologies for the development of the figure sensor, are illustrated. It is concluded that to select a particular implementation of the figure sensors, performance requirement will be refined and relevant technologies investigated further.

Full Text Available Layback spin is considered as one of the most beautiful and elegant spins performed in figure skating. It is also one of the required spins in competitive short program in female category. Different techniques of executing layback spin with variations in changing the positions of free parts of the body, as well as the evaluation of layback spin in accordance with ISU rules and regulations, which have been used in all International Skating Federation competitions since 2004 (World and European championships, Olympic Games are presented in this paper. Due to very difficult position of the body while performing a layback spin, it is essential that the skaters who want to master it should have excellent agility (especially of the spinal column and shoulder and knee joints and balance. Layback spin performance requires significant skating knowledge, so it cannot be performed by beginners. Depending on the fl exibility and creativity, a skater can execute various positions of the head, arms, body and free leg while performing a layback spin. In some cases, these variations can increase the level of difficulty, and in others only the mark given for executing this spin.

3. An economics figure of merit in ALPS

International Nuclear Information System (INIS)

Shatilla, Y.A.

2000-01-01

One of the most pressing issues facing the deregulated nuclear electric power industry is its economic competitiveness when compared to other sources of electrical power. Traditionally, finding the optimum loading pattern (LP) that meets all the safety and operational objective functions and at the same time produces the most attractive economical solutions is an iterative process. This is because (a) LP search tools usually lack the capability to generate equilibrium solutions and (b) economics objective functions are hard to include in the search process. In this paper, the Westinghouse Advanced Loading Pattern Search code (ALPS) has been demonstrated to successfully find LPs that meet user-defined operational and safety as well as economics objectives. This has been made possible by the development of TULIP language that allows the integration of external procedures into the search process of the main program, ALPS. In the example given, an economic figure of merit (EFM) has been defined and included via TULIP script into the fuel management optimization problem of a three-loop Westinghouse core operating an 18-month cycle. The LPs found by ALPS exhibit a clear trend of meeting and, in some cases, exceeding the EFM objective function defined for the ALPS search process a priori

2014-04-01

We examined how figure-ground segmentation occurs across multiple regions of a visual array during a visual search task. Stimuli consisted of arrays of black-and-white figure-ground images in which roughly half of each image depicted a meaningful object, whereas the other half constituted a less meaningful shape. The colours of the meaningful regions of the targets and distractors were either the same (congruent) or different (incongruent). We found that incongruent targets took longer to locate than congruent targets (Experiments 1, 2, and 3) and that this segmentation-congruency effect decreased when the number of search items was reduced (Experiment 2). Furthermore, an analysis of eye movements revealed that participants spent more time scrutinising the target before confirming its identity on incongruent trials than on congruent trials (Experiment 3). These findings suggest that the distractor context influences target segmentation and detection during visual search. Copyright © 2014 Elsevier B.V. All rights reserved.

5. Key figures for the regional- and distribution grid

International Nuclear Information System (INIS)

1996-02-01

In Norway, improving the efficiency of the hydroelectric grid operation is a stated goal of the Energy Act. Several studies have identified potential profits of such improvement. This publication focuses on costs and improvement potentials. Publication of key figures may stimulate grid owners, boards and administrations to improve the operating efficiency of their grids. The publication shows key figures for the regional- and distribution grid and is based on accounting data for 1994. The key figures are divided into: (1) Cost structure: The key figures express the relative contributions of each cost component to the total income of the grid, (2) Costs and physical quantities: The key figures show the cost of delivering the transport services, (3) Physical quantities: The key figures describe the working conditions of the energy utility. It appears that the cost structure of the sector varies considerably. The same is true of the cost related to the delivery of grid services. 30 figs., 6 tabs

6. Lighting, backlighting and watercolor illusions and the laws of figurality.

Science.gov (United States)

Pinna, Baingio; Reeves, Adam

2006-01-01

We report some novel 'lighting' and 'backlighting' effects in plane figures similar to those which induce the 'watercolor illusion', that is, figures made with outlines composed of juxtaposed parallel lines varying in brightness and chromatic color. These new effects show 'illumination' as an emergent percept, and show how arrangements of 'dark and light' along the boundaries of various plane figures model the volume and strengthen the illusion of depth. To account for these various effects we propose several phenomenological 'laws of figurality' to add to the Gestalt laws of organization and figure-ground segregation. We offer a set of meta-laws which are speculative but which serve to integrate and organize the phenomenological laws. These laws indicate how luminance gradient profiles across boundary contours define both the 3D appearance of figures and the properties of the light reflected from their volumetric shapes.

8. BOOK REVIEW: Relativistic Figures of Equilibrium

Science.gov (United States)

Mars, M.

2009-08-01

Compact fluid bodies in equilibrium under its own gravitational field are abundant in the Universe and a proper treatment of them can only be carried out using the full theory of General Relativity. The problem is of enormous complexity as it involves two very different regimes, namely the interior and the exterior of the fluid, coupled through the surface of the body. This problem is very challenging both from a purely theoretical point of view, as well as regarding the obtaining of realistic models and the description of their physical properties. It is therefore an excellent piece of news that the book 'Relativistic Figures of Equilibrium' by R Meinel, M Ansorg, A Kleinwächter, G Neugebauer and D Petroff has been recently published. This book approaches the topic in depth and its contents will be of interest to a wide range of scientists working on gravitation, including theoreticians in general relativity, mathematical physicists, astrophysicists and numerical relativists. This is an advanced book that intends to present some of the present-day results on this topic. The most basic results are presented rather succinctly, and without going into the details, of their derivations. Although primarily not intended to serve as a textbook, the presentation is nevertheless self-contained and can therefore be of interest both for experts on the field as well as for anybody wishing to learn more about rotating self-gravitating compact bodies in equilibrium. It should be remarked, however, that this book makes a rather strong selection of topics and concentrates fundamentally on presenting the main results obtained by the authors during their research in this field. The book starts with a chapter where the fundamental aspects of rotating fluids in equilibrium, including its thermodynamic properties, are summarized. Of particular interest are the so-called mass-shedding limit, which is the limit where the body is rotating so fast that it is on the verge of starting

9. Determination of the crystallite orientation distribution from direct pole figures

International Nuclear Information System (INIS)

Araujo Gomes, P.A.M. de.

1977-01-01

A method is described which allows to calculate the crystallite orientation distribution in polycrystalline material, from direct pole figures data of its crystallographic planes (Roe's Method). The programme was applied to (1010), (0002), (1011) and (1120) complete pole figures data for a commercial, thin sheet Zircaloy-4 tubing specimen. A semi-automatic Rigaku-Denki texture goniometer, which scans the reciprocal lattice sphere pointwise outputting the data in a punched tape, was used to obtain the pole figures. This is consistent with the results obtained through direct conclusion from the pole figures. (author)

10. Masking interrupts figure-ground signals in V1.

2002-10-01

In a backward masking paradigm, a target stimulus is rapidly (figure-ground segregation can be recorded. Here, we recorded from awake macaque monkeys, engaged in a task where they had to detect figures from background in a pattern backward masking paradigm. We show that the V1 figure-ground signals are selectively and fully suppressed at target-mask intervals that psychophysically result in the target being invisible. Initial response transients, signalling the features that make up the scene, are not affected. As figure-ground modulations depend on feedback from extrastriate areas, these results suggest that masking selectively interrupts the recurrent interactions between V1 and higher visual areas.

11. Familiar shapes attract attention in figure-ground displays.

Science.gov (United States)

Nelson, Rolf A; Palmer, Stephen E

2007-04-01

We report five experiments that explore the effect of figure-ground factors on attention. We hypothesized that figural cues, such as familiar shape, would draw attention to the figural side in an attentional cuing task using bipartite figure-ground displays. The first two experiments used faces in profile as the familiar shape and found a perceptual advantage for targets presented on the meaningful side of the central contour in detection speed (Experiment 1) and discrimination accuracy (Experiment 2). The third experiment demonstrated the figural advantage in response time (RT) with nine other familiar shapes (including a sea horse, a guitar, a fir tree, etc.), but only when targets appeared in close proximity to the contour. A fourth experiment obtained a figural advantage in a discrimination task with the larger set of familiar shapes. The final experiment ruled out eye movements as a possible confounding factor by replicating the RT advantage for targets on the figural side of face displays when all trials containing eye movements were eliminated. The results are discussed in terms of ecological influences on attention, and are cast within the framework of Yantis and Jonides's hypothesis that attention is exogenously drawn to the onset of new perceptual objects. We argue that the figural side constitutes an "object" whereas the ground side does not, and that figural cues such as shape familiarity are effective in determining which areas represent objects.

12. Surface reconstruction, figure-ground modulation, and border-ownership.

Jeurissen, Danique; Self, Matthew W; Roelfsema, Pieter R

2013-01-01

The Differentiation-Integration for Surface Completion (DISC) model aims to explain the reconstruction of visual surfaces. We find the model a valuable contribution to our understanding of figure-ground organization. We point out that, next to border-ownership, neurons in visual cortex code whether surface elements belong to a figure or the background and that this is influenced by attention. We furthermore suggest that there must be strong links between object recognition and figure-ground assignment in order to resolve the status of interior contours. Incorporation of these factors in neurocomputational models will further improve our understanding of surface reconstruction, figure-ground organization, and border-ownership.

14. Nanocrystalline solids

International Nuclear Information System (INIS)

Gleiter, H.

1991-01-01

Nanocrystalline solids are polycrystals, the crystal size of which is a few (typically 1 to 10) nanometres so that 50% or more of the solid consists of incoherent interfaces between crystals of different orientations. Solids consisting primarily of internal interfaces represent a separate class of atomic structures because the atomic arrangement formed in the core of an interface is known to be an arrangement of minimum energy in the potential field of the two adjacent crystal lattices with different crystallographic orientations on either side of the boundary core. These boundary conditions result in atomic structures in the interfacial cores which cannot be formed elsewhere (e.g. in glasses or perfect crystals). Nanocrystalline solids are of interest for the following four reasons: (1) Nanocrystalline solids exhibit an atomic structure which differs from that of the two known solid states: the crystalline (with long-range order) and the glassy (with short-range order). (2) The properties of nanocrystalline solids differ (in some cases by several orders of magnitude) from those of glasses and/or crystals with the same chemical composition, which suggests that they may be utilized technologically in the future. (3) Nanocrystalline solids seem to permit the alloying of conventionally immiscible components. (4) If small (1 to 10 nm diameter) solid droplets with a glassy structure are consolidated (instead of small crystals), a new type of glass, called nanoglass, is obtained. Such glasses seem to differ structurally from conventional glasses. (orig.)

7. Figure-Ground Processing: A Reassessment of Gelb and Granit.

Science.gov (United States)

Nelson, Rolf; Hebda, Nicholas

2018-03-01

In 1923, Adhemar Gelb and Ragnar Granit, two prominent researchers in early Gestalt perceptual theory, reported a lower threshold for detection of a target (a small colored dot) on the ground region of an image than on an adjacent figural region. Although their results had a wide influence on the understanding of figure-ground perception, they are at odds with more recent investigations in which figural regions appear to have a processing advantage over ground regions. The two present studies replicated Gelb and Granit's experiment using a similar figure-ground stimulus albeit with a two-alternative forced choice procedure rather than their original method of adjustment. Experiment 1 found that, contrary to Gelb and Granit's findings, a detection advantage was found for the figural over the ground region. Experiment 2 indicated that explicit contours might have played a role in detection.

8. Lower region: a new cue for figure-ground assignment.

Science.gov (United States)

Vecera, Shaun P; Vogel, Edward K; Woodman, Geoffrey F

2002-06-01

Figure-ground assignment is an important visual process; humans recognize, attend to, and act on figures, not backgrounds. There are many visual cues for figure-ground assignment. A new cue to figure-ground assignment, called lower region, is presented: Regions in the lower portion of a stimulus array appear more figurelike than regions in the upper portion of the display. This phenomenon was explored, and it was demonstrated that the lower-region preference is not influenced by contrast, eye movements, or voluntary spatial attention. It was found that the lower region is defined relative to the stimulus display, linking the lower-region preference to pictorial depth perception cues. The results are discussed in terms of the environmental regularities that this new figure-ground cue may reflect.

Seventy-two human figure drawings by forty-three patients who had a diagnosis of Duchenne's muscular dystrophy were examined. The study includes a description of these human figure drawings according to eleven emotional indicators and according to directionality quadrants. When the human figure drawings were used as a projective tool, four personality traits of some of the children were identified: physical inadequacy, immaturity, body anxiety, and insecurity. Both the emotional indicators and the quadrant in which the figures appeared were examined in relation to stages of the disease process to see if the human figure drawings of the children might reflect more stress and anxiety at a particular stage of the disease. Suggestions for improvements and recommendations for future study are given.

Science.gov (United States)

Dimiccoli, Mariella

2016-09-01

We present a computational model that computes and integrates in a nonlocal fashion several configural cues for automatic figure-ground segregation. Our working hypothesis is that the figural status of each pixel is a nonlocal function of several geometric shape properties and it can be estimated without explicitly relying on object boundaries. The methodology is grounded on two elements: multi-directional linear voting and nonlinear diffusion. A first estimation of the figural status of each pixel is obtained as a result of a voting process, in which several differently oriented line-shaped neighborhoods vote to express their belief about the figural status of the pixel. A nonlinear diffusion process is then applied to enforce the coherence of figural status estimates among perceptually homogeneous regions. Computer simulations fit human perception and match the experimental evidence that several cues cooperate in defining figure-ground segregation. The results of this work suggest that figure-ground segregation involves feedback from cells with larger receptive fields in higher visual cortical areas. Copyright © 2015 Elsevier Ltd.

14. Figure-ground segmentation can occur without attention.

Science.gov (United States)

Kimchi, Ruth; Peterson, Mary A

2008-07-01

The question of whether or not figure-ground segmentation can occur without attention is unresolved. Early theorists assumed it can, but the evidence is scant and open to alternative interpretations. Recent research indicating that attention can influence figure-ground segmentation raises the question anew. We examined this issue by asking participants to perform a demanding change-detection task on a small matrix presented on a task-irrelevant scene of alternating regions organized into figures and grounds by convexity. Independently of any change in the matrix, the figure-ground organization of the scene changed or remained the same. Changes in scene organization produced congruency effects on target-change judgments, even though, when probed with surprise questions, participants could report neither the figure-ground status of the region on which the matrix appeared nor any change in that status. When attending to the scene, participants reported figure-ground status and changes to it highly accurately. These results clearly demonstrate that figure-ground segmentation can occur without focal attention.

19. Figural properties are prioritized for search under conditions of uncertainty: Setting boundary conditions on claims that figures automatically attract attention.

Science.gov (United States)

Peterson, Mary A; Mojica, Andrew J; Salvagio, Elizabeth; Kimchi, Ruth

2017-01-01

Nelson and Palmer (2007) concluded that figures/figural properties automatically attract attention, after they found that participants were faster to detect/discriminate targets appearing where a portion of a familiar object was suggested in an otherwise ambiguous display. We investigated whether these effects are truly automatic and whether they generalize to another figural property-convexity. We found that Nelson and Palmer's results do generalize to convexity, but only when participants are uncertain regarding when and where the target will appear. Dependence on uncertainty regarding target location/timing was also observed for familiarity. Thus, although we could replicate and extend Nelson and Palmer's results, our experiments showed that figures do not automatically draw attention. In addition, our research went beyond Nelson and Palmer's, in that we were able to separate figural properties from perceived figures. Because figural properties are regularities that predict where objects lie in the visual field, our results join other evidence that regularities in the environment can attract attention. More generally, our results are consistent with Bayesian theories in which priors are given more weight under conditions of uncertainty.

20. Effects of orientation on Rey complex figure performance.

Ferraro, F Richard; Grossman, Jennifer; Bren, Amy; Hoverson, Allysa

2002-10-01

An experiment was performed that examined the impact of stimulus orientation on performance on the Rey complex figure. A total of 48 undergraduates (24 men, 24 women) were randomly assigned to one of four Rey figure orientation groups (0 degrees, 90 degrees, 180 degrees, and 270 degrees ). Participants followed standard procedures for the Rey figure, initially copying it in whatever orientation group they were assigned to. Next, all participants performed a 15-20 min lexical decision experiment, used as a filler task. Finally, and unbeknownest to them, participants were asked to recall as much of the figure as they could. As expected, results revealed a main effect of Task (F = 83.92, p orientation was not significant, nor did orientation interact with task (Fs .57). The results are important from an applied setting, especially if testing conditions are less than optimal and a fixed stimulus position is not possible (e.g., testing at the bedside).

Neri, Peter; Levi, Dennis M

2007-01-01

The segregation of figure from ground is arguably one of the most fundamental operations in human vision. Neural signals reflecting this operation appear in cortex as early as 50 ms and as late as 300 ms after presentation of a visual stimulus, but it is not known when these signals are used by the brain to construct the percepts of figure and ground. We used psychophysical reverse correlation to identify the temporal window for figure-ground signals in human perception and found it to lie within the range of 100-160 ms. Figure enhancement within this narrow temporal window was transient rather than sustained as may be expected from measurements in single neurons. These psychophysical results prompt and guide further electrophysiological studies.

6. A search asymmetry reversed by figure-ground assignment.

Science.gov (United States)

Humphreys, G W; Müller, H

2000-05-01

We report evidence demonstrating that a search asymmetry favoring concave over convex targets can be reversed by altering the figure-ground assignment of edges in shapes. Visual search for a concave target among convex distractors is faster than search for a convex target among concave distractors (a search asymmetry). By using shapes with ambiguous local figure-ground relations, we demonstrated that search can be efficient (with search slopes around 10 ms/item) or inefficient (with search slopes around 30-40 ms/item) with the same stimuli, depending on whether edges are assigned to concave or convex "figures." This assignment process can operate in a top-down manner, according to the task set. The results suggest that attention is allocated to spatial regions following the computation of figure-ground relations in parallel across the elements present. This computation can also be modulated by top-down processes.

10. Noise destroys feedback enhanced figure-ground segmentation but not feedforward figure-ground segmentation

Science.gov (United States)

Romeo, August; Arall, Marina; Supèr, Hans

2012-01-01

Figure-ground (FG) segmentation is the separation of visual information into background and foreground objects. In the visual cortex, FG responses are observed in the late stimulus response period, when neurons fire in tonic mode, and are accompanied by a switch in cortical state. When such a switch does not occur, FG segmentation fails. Currently, it is not known what happens in the brain on such occasions. A biologically plausible feedforward spiking neuron model was previously devised that performed FG segmentation successfully. After incorporating feedback the FG signal was enhanced, which was accompanied by a change in spiking regime. In a feedforward model neurons respond in a bursting mode whereas in the feedback model neurons fired in tonic mode. It is known that bursts can overcome noise, while tonic firing appears to be much more sensitive to noise. In the present study, we try to elucidate how the presence of noise can impair FG segmentation, and to what extent the feedforward and feedback pathways can overcome noise. We show that noise specifically destroys the feedback enhanced FG segmentation and leaves the feedforward FG segmentation largely intact. Our results predict that noise produces failure in FG perception. PMID:22934028

11. Brand logo design: Examining consumer responses to figurativeness

OpenAIRE

Machado, J. C.; Vacas-Carvalho, Leonor; Costa, P.; Torres, A.

In a previous investigation, aimed at studying brand identity preferences in a merger context, researchers found the most preferred logos are figurative ones. Additionally, results suggested the aesthetic appeal of the logo significantly influences consumers’ identity choices. These results find support in logo strategy literature. The main purpose of this study is to investigate more thoroughly the influence of logo design characteristics, and particularly of figurativeness, o...

Figure-ground plans show the footprints of buildings and the pattern of unbuilt voids in urban space. Compared historically they reveal the erosion of the public realm over time and provide an analytical basis for tissue repair. The paper traces the communicative power of figure-ground technique to its roots in gestalt psychology, and follows its revival from Colin Rowe’s studio at Cornell through to controversies in post-reunification Berlin. The impact of computerisation is discussed and th...

14. Attention and competition in figure-ground perception.

Science.gov (United States)

Peterson, Mary A; Salvagio, Elizabeth

2009-01-01

What are the roles of attention and competition in determining where objects lie in the visual field, a phenomenon known as figure-ground perception? In this chapter, we review evidence that attention and other high-level factors such as familiarity affect figure-ground perception, and we discuss models that implement these effects. Next, we consider the Biased Competition Model of Attention in which attention is used to resolve the competition for neural representation between two nearby stimuli; in this model the response to the stimulus that loses the competition is suppressed. In the remainder of the chapter we discuss recent behavioral evidence that figure-ground perception entails between-object competition in which the response to the shape of the losing competitor is suppressed. We also describe two experiments testing whether more attention is drawn to resolve greater figure-ground competition, as would be expected if the Biased Competition Model of Attention extends to figure-ground perception. In these experiments we find that responses to targets on the location of a losing strong competitor are slowed, consistent with the idea that the location of the losing competitor is suppressed, but responses to targets on the winning competitor are not speeded, which is inconsistent with the hypothesis that attention is used to resolve figure-ground competition. In closing, we discuss evidence that attention can operate by suppression as well as by facilitation.

15. Figurativeness in the Sense of Distraction (Studies by Lithuanian Authors

Full Text Available The phenomenon of the sense of distraction and the feature of figurativeness in it are analysed with the help of phenomenological description, the concept of sense of Juozas Mureika and the conception of imagination of Kristupas Sabolius. The position is followed that the acts of sense and the being of those existing found in them cannot be known in a purely rational way. Knowing is reached with intuitive insights. The experiencing of distraction is approached as one of the norms or intentions of consciousness. The sense of distraction is acknowledged to be a basic value becoming more and more important in a modern stressful life. The article indicates that the intentional beings of the sense of distraction are expressed in really various human activities and are distinguished with mono-subjectivity and unrepeatable feeling. Figurativeness is perceived as the result of imaginary, creative activity of the imagination and aesthetical quality. The peculiarities of the formation of figurativeness are revealed through the phenomenological description of imagination by Sabolius. Four features of the act of visualisation, determining the quality of figurativeness, are emphasized: intentionality, power of transformation, relation with emotions and the symbolism of the image. The conclusion is made that figurativeness, being the result of the creative act (visualisation of imagination, appears as aesthetical quality or the ensemble of qualities. Figurativeness sharpens the sense of distraction and calls the wave of new experiences.

16. Local figure-ground cues are valid for natural images.

Fowlkes, Charless C; Martin, David R; Malik, Jitendra

Figure-ground organization refers to the visual perception that a contour separating two regions belongs to one of the regions. Recent studies have found neural correlates of figure-ground assignment in V2 as early as 10-25 ms after response onset, providing strong support for the role of local bottom-up processing. How much information about figure-ground assignment is available from locally computed cues? Using a large collection of natural images, in which neighboring regions were assigned a figure-ground relation by human observers, we quantified the extent to which figural regions locally tend to be smaller, more convex, and lie below ground regions. Our results suggest that these Gestalt cues are ecologically valid, and we quantify their relative power. We have also developed a simple bottom-up computational model of figure-ground assignment that takes image contours as input. Using parameters fit to natural image statistics, the model is capable of matching human-level performance when scene context limited.

17. Solid biomass barometer

The primary energy production from solid biomass in the European Union reached 79.3 Mtoe in 2010 which implies a growth rate of 8% between 2009 and 2010. The trend, which was driven deeper by Europe's particularly cold winter of 2009-2010, demonstrates that the economic down-turn failed to weaken the member states' efforts to structure the solid biomass sector. Heat consumption rose sharply: the volume of heat sold by heating networks increased by 18% and reached 6.7 Mtoe and if we consider the total heat consumption (it means with and without recovery via heating networks) the figure is 66 Mtoe in 2010, which amounts to 10.1% growth. The growth of electricity production continued through 2010 (8.3% up on 2009) and rose to 67 TWh but at a slower pace than in 2009 (when it rose by 11.3% on 2008). The situation of the main producer countries: Sweden, Finland, Germany and France is reviewed. It appears that cogeneration unit manufacturers and biomass power plant constructors are the main beneficiaries of the current biomass energy sector boom. There is a trend to replace coal-fired plants that are either obsolete or near their end of life with biomass or multi-fuel plants. These opportunities will enable the industry to develop and further exploit new technologies such as gasification, pyrolysis and torrefaction which will enable biomass to be turned into bio-coal.

Full Text Available L'art médical est fréquemment utilisé par Platon pour penser de façon analogique la construction de la science politique et ses difficultés. Une lecture comparée des usages de cette analogie dans le Gorgias et le Politique permet de montrer de quelle façon Platon utilise cette analogie, et à quel moment précis il s'en défait pour indiquer la différence entre un art des cas (la médecine et un art des codes (la politique. Au contraire, Averroès, dans son Exposition sur la République de Platon, reprend l'analogie entre médecine et politique d'un point de vue épistémologique, pour mettre en évidence l'identique articulation interne que connaissent ces deux disciplines, et qui permet d'y distinguer chaque fois un art et une science, ou une pratique et une théorie. Averroès se présente ainsi, dans la mesure même où il contourne le problème soulevé par Platon, comme l'initiateur d'une longue tradition d'usage de l'analogie médico-politique, qui va se poursuivre du XIIIe au XVIe siècles pour élucider la structure épistémologique de la science politique.

In everyday acoustic scenes, figure-ground segregation typically requires one to group together sound elements over both time and frequency. Electroencephalogram was recorded while listeners detected repeating tonal complexes composed of a random set of pure tones within stimuli consisting of randomly varying tonal elements. The repeating pattern was perceived as a figure over the randomly changing background. It was found that detection performance improved both as the number of pure tones making up each repeated complex (figure coherence) increased, and as the number of repeated complexes (duration) increased - i.e., detection was easier when either the spectral or temporal structure of the figure was enhanced. Figure detection was accompanied by the elicitation of the object related negativity (ORN) and the P400 event-related potentials (ERPs), which have been previously shown to be evoked by the presence of two concurrent sounds. Both ERP components had generators within and outside of auditory cortex. The amplitudes of the ORN and the P400 increased with both figure coherence and figure duration. However, only the P400 amplitude correlated with detection performance. These results suggest that 1) the ORN and P400 reflect processes involved in detecting the emergence of a new auditory object in the presence of other concurrent auditory objects; 2) the ORN corresponds to the likelihood of the presence of two or more concurrent sound objects, whereas the P400 reflects the perceptual recognition of the presence of multiple auditory objects and/or preparation for reporting the detection of a target object.

When reading bioscience journal articles, many researchers focus attention on the figures and their captions. This observation led to the development of the BioText literature search engine, a freely available Web-based application that allows biologists to search over the contents of Open Access Journals, and see figures from the articles displayed directly in the search results. This article presents a qualitative assessment of this system in the form of a usability study with 20 biologist participants using and commenting on the system. 19 out of 20 participants expressed a desire to use a bioscience literature search engine that displays articles' figures alongside the full text search results. 15 out of 20 participants said they would use a caption search and figure display interface either frequently or sometimes, while 4 said rarely and 1 said undecided. 10 out of 20 participants said they would use a tool for searching the text of tables and their captions either frequently or sometimes, while 7 said they would use it rarely if at all, 2 said they would never use it, and 1 was undecided. This study found evidence, supporting results of an earlier study, that bioscience literature search systems such as PubMed should show figures from articles alongside search results. It also found evidence that full text and captions should be searched along with the article title, metadata, and abstract. Finally, for a subset of users and information needs, allowing for explicit search within captions for figures and tables is a useful function, but it is not entirely clear how to cleanly integrate this within a more general literature search interface. Such a facility supports Open Access publishing efforts, as it requires access to full text of documents and the lifting of restrictions in order to show figures in the search interface.

6. Inhibitory competition in figure-ground perception: context and convexity.

Science.gov (United States)

Peterson, Mary A; Salvagio, Elizabeth

2008-12-15

Convexity has long been considered a potent cue as to which of two regions on opposite sides of an edge is the shaped figure. Experiment 1 shows that for a single edge, there is only a weak bias toward seeing the figure on the convex side. Experiments 1-3 show that the bias toward seeing the convex side as figure increases as the number of edges delimiting alternating convex and concave regions increases, provided that the concave regions are homogeneous in color. The results of Experiments 2 and 3 rule out a probability summation explanation for these context effects. Taken together, the results of Experiments 1-3 show that the homogeneity versus heterogeneity of the convex regions is irrelevant. Experiment 4 shows that homogeneity of alternating regions is not sufficient for context effects; a cue that favors the perception of the intervening regions as figures is necessary. Thus homogeneity alone does not alone operate as a background cue. We interpret our results within a model of figure-ground perception in which shape properties on opposite sides of an edge compete for representation and the competitive strength of weak competitors is further reduced when they are homogeneous.

7. Reduced cost and improved figure of sapphire optical components

Sapphire presents many challenges to optical manufacturers due to its high hardness and anisotropic properties. Long lead times and high prices are the typical result of such challenges. The cost of even a simple 'grind and shine' process can be prohibitive. The high precision surfaces required by optical sensor applications further exacerbate the challenge of processing sapphire thereby increasing cost further. Optimax has demonstrated a production process for such windows that delivers over 50% time reduction as compared to traditional manufacturing processes for sapphire, while producing windows with less than 1/5 wave rms figure error. Optimax's sapphire production process achieves significant improvement in cost by implementation of a controlled grinding process to present the best possible surface to the polishing equipment. Following the grinding process is a polishing process taking advantage of chemical interactions between slurry and substrate to deliver excellent removal rates and surface finish. Through experiments, the mechanics of the polishing process were also optimized to produce excellent optical figure. In addition to reducing the cost of producing large sapphire sensor windows, the grinding and polishing technology Optimax has developed aids in producing spherical sapphire components to better figure quality. In addition to reducing the cost of producing large sapphire sensor windows, the grinding and polishing technology Optimax has developed aids in producing spherical sapphire components to better figure quality. Through specially developed polishing slurries, the peak-to-valley figure error of spherical sapphire parts is reduced by over 80%.

To promote the development of the intangible cultural heritage of the world, shadow play, many studies have focused on shadow puppet modeling and interaction. Most of the shadow puppet figures are still imaginary, spread by ancients, or carved and painted by shadow puppet artists, without consideration of real dimensions or the appearance of human bodies. This study proposes an algorithm to transform 3D human models to 2D puppet figures for shadow puppets, including automatic location of feature points, automatic segmentation of 3D models, automatic extraction of 2D contours, automatic clothes matching, and animation. Experiment proves that more realistic and attractive figures and animations of the shadow puppet can be generated in real time with this algorithm.

Figure drawings were obtained from 97 preadolescent males who differed in self and behavioral assessments of self-esteem. These subjects had been selected from a much larger sample and represented five different types of self-esteem. The figure drawings were scored for 15 variables, dealing with formal characteristics, content, and global-interpretations of the total drawings. Five significant differences were obtained, with the content and global-interpretative categories proving more differentiating between self-esteem groups than did the formal characteristics. Behavioral expressions of self-esteem were more associated with figure drawing characteristics than were subjective evaluations. Discussion focuses on the nature of self-concept and self-esteem in children as a sensorimotor rather than symbolic expression.

11. Brief report: human figure drawings by children with Asperger's syndrome.

2008-05-01

Twenty-nine children with Asperger's syndrome and 28 typically developing children, matched on gender, chronological age and nonverbal IQ, were asked to produce a free drawing, then requested to draw a person, a house and a tree. The drawings were scored using standardized procedures for assessing accuracy, detail and complexity. There were no differences between the diagnostic groups on the tree or house drawing scores. The human figure drawing scores of children with Asperger's syndrome were significantly lower than those of the typically developing children, and there was a positive correlation between human figure drawing scores and communication sub-scores on the Vineland Adaptive Behaviour Scales, for the Asperger's group. These results suggest that the selective deficit in generating human figure representations may derive from a relative lack of interest in the social world, and/or limited practice in drawing people.

In a series of three studies, characteristics of novel figurative phrases were compared with those of established idioms. Studies 1 and 2 found that certain correlations were found to be strong and in one direction for familiar idioms and comparably strong but in the opposite direction for novel figurative phrases, with the correlations for less familiar idioms usually falling partway between these extremes. Study 2 also noted that written or auditory presentation had minimal effects on characteristic ratings. In Study 3 the correlations among characteristics stayed relatively constant for familiar idioms after one, three, or six presentations, but for the novel figurative phrases, after multiple presentations the correlations changed in the direction of the established idioms.

13. Stochastic correlative firing for figure-ground segregation.

Science.gov (United States)

Chen, Zhe

2005-03-01

Segregation of sensory inputs into separate objects is a central aspect of perception and arises in all sensory modalities. The figure-ground segregation problem requires identifying an object of interest in a complex scene, in many cases given binaural auditory or binocular visual observations. The computations required for visual and auditory figure-ground segregation share many common features and can be cast within a unified framework. Sensory perception can be viewed as a problem of optimizing information transmission. Here we suggest a stochastic correlative firing mechanism and an associative learning rule for figure-ground segregation in several classic sensory perception tasks, including the cocktail party problem in binaural hearing, binocular fusion of stereo images, and Gestalt grouping in motion perception.

Gori, Simone; Giora, Enrico; Pedersini, Riccardo

2008-11-01

In a series of experiments using ambiguous stimuli, we investigate the effects of displaying ordered, discrete series of images on the dynamics of figure-ground segregation. For low frame presentation speeds, the series were perceived as a sequence of discontinuous, static images, while for high speeds they were perceived as continuous. We conclude that using stimuli varying continuously along one parameter results in stronger hysteresis and reduces spontaneous switching compared to matched static stimuli with discontinuous parameter changes. The additional evidence that the size of the hysteresis effects depended on trial duration is consistent with the stochastic nature of the dynamics governing figure-ground segregation. The results showed that for continuously changing stimuli, alternative figure-ground organizations are resolved via low-level, dynamical competition. A second series of experiments confirmed these results with an ambiguous stimulus based on Petter's effect.

A new type of 'central display system of figures in fire alarm' includes two parts: (1) software package of drawing picture; (2) real time processing and operate system (POS). Main function of the software package is to draw floor plane figures, fire-fighting facility signs and room numbers; and then all pictures are used in POS. Main functions of POS are to process fire alarm, faults and activation of fire fighting control facility, save and print reports, look over floor plane figures, look over concrete condition of fire fighting facilities, and to show appropriate prompt according to different case. This system realizes many functions, such as, control with mouse, operation with push-button, menu operation interface, flip windows to prompt, and chinese character. It have won acclaim for its amazing interface, its convenience to operate, its reliability and flexibility

Carroll, M K; Ryan-Wenger, N A

1999-01-01

The purpose of this study was to identify the fears of school-age children and determine the relationship between fear and anxiety. A descriptive, correlational, secondary analysis study was conducted using a convenience sample of 90 children between the ages of 8 and 12 years. Each child was instructed to complete the Revised Children's Anxiety Scale and then answer questions from a structured interview. On completion, each child was instructed to draw a human figure drawing. Frequency charts and correlational statistics were used to analyze the data. Findings indicated that the most significant fears of the boys were in the categories of animals, safety, school, and supernatural phenomena, whereas girls were more fearful of natural phenomena. High correlations existed between anxiety scores and the number of fears and emotional indicators on human figure drawings. Because human figure drawings are reliable tools for assessing anxiety and fears in children, practitioners should incorporate these drawings as part of their routine assessments of fearful children.

We investigated which correlates of figure-ground-segregation can be detected by means of functional magnetic resonance imaging (fMRI). Five subjects were scanned with a Siemens Vision 1.5 T system. Motion, colour, and luminance-defined checkerboards were presented with alternating control conditions containing one of the two features of the checkerboard. We find a segregation-specific activation in V1 for all subjects and all stimuli and conclude that neural mechanisms exist as early as in the primary visual cortex that are sensitive to figure-ground segregation.

After having recalled the different French, European and world objectives in terms of greenhouse gas emission reduction (globally or for different sectors: industry, housing and offices, transport, agriculture), and of renewable energy production and consumption, this document proposes data tables and figures describing the energy consumption evolution in France since 1970 (with respect to sectors as well as with respect to energy sources), the greenhouse gas emission evolution since 1990 and the share of each sector in these emissions. Other tables and figures give a more precise description of the housing sector, of the office buildings sector, of the transportation sector, of the manufacturing industry, and of renewable energies (production capacity, purchase tariffs)

Full Text Available Visual recognition features of images with different figure-ground segregation have been considered in the article. The research was carried out within the framework of Sokolov and Izmaylov’s spherical model and was based on the construction of color objects discrimination models depending on the changes of background characteristics. The research has revealed the specific influence of the background on figure discrimination. The derived models reflect the mechanisms of the all-in-one perception of the visual space.

2. Threshold Differences on Figure and Ground: Gelb and Granit (1923).

2017-01-01

In 1923, Gelb and Granit, using a method of adjustment for a small red light, reported a lower threshold for the target when presented on a ground region than on an adjacent figural region. More recent work in perceptual organization has found precisely the opposite-a processing advantage seems to go to items presented on the figure, not the ground. Although Gelb and Granit continue to be cited for their finding, it has not previously been available as an English translation. Understanding their methodology and results is important for integrating early Gestalt theory with more recent investigations.

14. The role of figure-ground segregation in change blindness.

Science.gov (United States)

Landman, Rogier; Spekreijse, Henk; Lamme, Victor A F

2004-04-01

Partial report methods have shown that a large-capacity representation exists for a few hundred milliseconds after a picture has disappeared. However, change blindness studies indicate that very limited information remains available when a changed version of the image is presented subsequently. What happens to the large-capacity representation? New input after the first image may interfere, but this is likely to depend on the characteristics of the new input. In our first experiment, we show that a display containing homogeneous image elements between changing images does not render the large-capacity representation unavailable. Interference occurs when these new elements define objects. On that basis we introduce a new method to produce change blindness: The second experiment shows that change blindness can be induced by redefining figure and background, without an interval between the displays. The local features (line segments) that defined figures and background were swapped, while the contours of the figures remained where they were. Normally, changes are easily detected when there is no interval. However, our paradigm results in massive change blindness. We propose that in a change blindness experiment, there is a large-capacity representation of the original image when it is followed by a homogeneous interval display, but that change blindness occurs whenever the changed image forces resegregation of figures from the background.

19. Ion beam figuring of CVD silicon carbide mirrors

Science.gov (United States)

Gailly, P.; Collette, J.-P.; Fleury Frenette, K.; Jamar, C.

2017-11-01

Optical and structural elements made of silicon carbide are increasingly found in space instruments. Chemical vapor deposited silicon carbide (CVD-SiC) is used as a reflective coating on SiC optics in reason of its good behavior under polishing. The advantage of applying ion beam figuring (IBF) to CVD-SiC over other surface figure-improving techniques is discussed herein. The results of an IBF sequence performed at the Centre Spatial de Liège on a 100 mm CVD-SiC mirror are reported. The process allowed to reduce the mirror surface errors from 243 nm to 13 nm rms . Beside the surface figure, roughness is another critical feature to consider in order to preserve the optical quality of CVD-SiC . Thus, experiments focusing on the evolution of roughness were performed in various ion beam etching conditions. The roughness of samples etched at different depths down to 3 ≠m was determined with an optical profilometer. These measurements emphasize the importance of selecting the right combination of gas and beam energy to keep roughness at a low level. Kaufman-type ion sources are generally used to perform IBF but the performance of an end-Hall ion source in figuring CVD-SiC mirrors was also evaluated in this study. In order to do so, ion beam etching profiles obtained with the end-Hall source on CVD-SiC were measured and used as a basis for IBF simulations.

4. A feedback model of figure-ground assignment.

Science.gov (United States)

Domijan, Drazen; Setić, Mia

2008-05-30

A computational model is proposed in order to explain how bottom-up and top-down signals are combined into a unified perception of figure and background. The model is based on the interaction between the ventral and the dorsal stream. The dorsal stream computes saliency based on boundary signals provided by the simple and the complex cortical cells. Output from the dorsal stream is projected to the surface network which serves as a blackboard on which the surface representation is formed. The surface network is a recurrent network which segregates different surfaces by assigning different firing rates to them. The figure is labeled by the maximal firing rate. Computer simulations showed that the model correctly assigns figural status to the surface with a smaller size, a greater contrast, convexity, surroundedness, horizontal-vertical orientation and a higher spatial frequency content. The simple gradient of activity in the dorsal stream enables the simulation of the new principles of the lower region and the top-bottom polarity. The model also explains how the exogenous attention and the endogenous attention may reverse the figural assignment. Due to the local excitation in the surface network, neural activity at the cued region will spread over the whole surface representation. Therefore, the model implements the object-based attentional selection.

9. Epidemiology of Figure Skating Injuries: A Review of the Literature.

Han, Julie S; Geminiani, Ellen T; Micheli, Lyle J

2018-05-01

As the popularity and technical demands of figure skating increase, so will the number of athletes presenting with sport-related problems. Searches were performed across PubMed from 1980 to 2017. The keywords searched were skating, skaters, incidence, and injuries. The search was limited to English-language articles and human participants. Relevant articles were cross-referenced. Clinical review. Level 5. Previous studies suggest an increase in incidence of figure skating injuries from 1982 to 2003. When combining all disciplines of figure skating, there is a similar proportion of acute and overuse injuries. Within disciplines, overuse injuries appear to be more common in singles skating, while acute injuries are more common in pairs skating, ice dancing, and synchronized skating. Lower extremity injuries are more common than upper extremity injuries in all disciplines, and pairs skating accounts for the majority of upper extremity injuries. Ankle sprains are the most common skating injury, and patellar tendinitis is the most common overuse injury across all disciplines. Stress fractures are the most common overuse injury in female singles skaters. The predominance of overuse injuries in singles disciplines reflects their increasing technical difficulty, with more difficult jumps and longer training hours. Partner disciplines are more likely to involve acute injuries and upper extremity injuries due to high-risk throws and lifts. Emphasis should be placed on properly fitting skating boots, intrinsic foot and ankle strengthening, and lower extremity flexibility, which may prevent many of the common lower extremity and back injuries in figure skating.

Full Text Available Abstract Background Figure rating scales were developed as a tool to determine body dissatisfaction in women, men, and children. However, it lacks in the literature the validation of the scale for body silhouettes previously adapted. We aimed to obtain evidence for construct validity of a figure rating scale for Brazilian adolescents. Methods The study was carried out with adolescent students attending three public schools in an urban region of the municipality of Florianopolis in the State of Santa Catarina (SC. The sample comprised 232 10-19-year-old students, 106 of whom are boys and 126 girls, from the 5th "series" (i.e. year of Primary School to the 3rd year of Secondary School. Data-gathering involved the application of an instrument containing 8 body figure drawings representing a range of children's and adolescents' body shapes, ranging from very slim (contour 1 to obese (contour 8. Weights and heights were also collected, and body mass index (BMI was calculated later. BMI was analyzed as a continuous variable, using z-scores, and as a dichotomous categorical variable, representing a diagnosis of nutritional status (normal and overweight including obesity. Results Results showed that both males and females with larger BMI z-scores chose larger body contours. Girls with higher BMI z-scores also show higher values of body image dissatisfaction. Conclusion We provided the first evidence of validity for a figure rating scale for Brazilian adolescents.

18. Research as Art: Using figures to make science approachable

Science.gov (United States)

Rabinowitz, H. S.; Barth, A.; Russell, J. B.; Frischkorn, K.; Yehudai, M.

2017-12-01

As scientists, we spend a significant amount of time thinking about how best to express the results of our research through figures. These can range from graphs to microscope images to movies, but they all serve the purpose of communicating complicated ideas to our colleagues in the scientific community. One component of scientific data representation that is often overlooked is the aesthetic of the image. Many images produced for data communication and publication are visually engaging even to a lay audience, allowing them to serve as a point of entry to learning about scientific research for the non-specialist. To help researchers embrace this secondary goal of scientific figures, we have instituted an annual event at the Lamont-Doherty Earth Observatory of Columbia University (LDEO) called Research as Art. For this event, scientists submit figures from their work that they see as artistic. These figures are displayed in a gallery-type exhibit for the community to appreciate. This year, the exhibit included movie and sculpture categories, allowing for attendees to interact with a broader range of scientific work. Each piece is accompanied by a brief, non-technical caption. Research as Art provides a gateway for scientists from a broad range of disciplines within the Earth Sciences to learn about work that is entirely unrelated to their own. After the event, attendees commented that they had never before thought about how a non-specialist would view their figures and that they would keep this in mind when making future figures. Thus, one of the biggest benefits of exhibits such as this is to teach scientists to view our work through a non-specialist's eyes. However, future plans for Research as Art include establishing a temporary exhibit at a local bar to expand the reach to a broader segment of the Columbia University area community. Our figures are art, and when we start to treat them that way, we open a world of possibilities for teaching the public about our

19. Processing convexity and concavity along a 2-D contour: figure-ground, structural shape, and attention.

Science.gov (United States)

Bertamini, Marco; Wagemans, Johan

2013-04-01

Interest in convexity has a long history in vision science. For smooth contours in an image, it is possible to code regions of positive (convex) and negative (concave) curvature, and this provides useful information about solid shape. We review a large body of evidence on the role of this information in perception of shape and in attention. This includes evidence from behavioral, neurophysiological, imaging, and developmental studies. A review is necessary to analyze the evidence on how convexity affects (1) separation between figure and ground, (2) part structure, and (3) attention allocation. Despite some broad agreement on the importance of convexity in these areas, there is a lack of consensus on the interpretation of specific claims--for example, on the contribution of convexity to metric depth and on the automatic directing of attention to convexities or to concavities. The focus is on convexity and concavity along a 2-D contour, not convexity and concavity in 3-D, but the important link between the two is discussed. We conclude that there is good evidence for the role of convexity information in figure-ground organization and in parsing, but other, more specific claims are not (yet) well supported.

20. Figurative language processing in atypical populations: The ASD perspective

Mila eVulchanova

2015-02-01

Full Text Available This paper is intended to provide a critical overview of experimental and clinical research documenting problems in figurative language processing in atypical populations with a focus on the Autistic Spectrum. Research in the comprehension and processing of figurative language in autism invariably documents problems in this area. The greater paradox is that even at the higher end of the spectrum or in the cases of linguistically talented individuals with Asperger syndrome, where structural language competence is intact, problems with extended language persist. If we assume that figurative and extended uses of language essentially depend on the perception and processing of more concrete core concepts and phenomena, the commonly observed failure in atypical populations to understand figurative language remains a puzzle.Various accounts have been offered to explain this issue, ranging from linking potential failure directly to overall structural language competence (Brock et al., 2008; Norbury, 2005 to right-hemispheric involvement (Gold and Faust, 2010. We argue that the dissociation between structural language and figurative language competence in autism should be sought in more general cognitive mechanisms and traits in the autistic phenotype (e.g., in terms of weak central coherence, Vulchanova et al., 2012b, as well as failure at on-line semantic integration with increased complexity and diversity of the stimuli (Coulson and van Petten, 2002. This perspective is even more compelling in light of similar problems in a number of conditions, including both acquired (e.g., Aphasia and developmental disorders (Williams Syndrome. This dissociation argues against a simple continuity view of language interpretation.

The preferential orientation, not alone it exists in metals, but also in minerals or in general in crystalline materials, notwithstanding in the metals it can be transformed by means of those processes of having mechanical worked such as laminate, wrapping, etc. To the preferable orientation of the crystals is also known as texture and since the properties of the crystalline materials lens depend on the orientation that present its glasses, it is important to know its texture. The difficulty for to represent and to describe the grade of preferential orientation in textured materials take to F. Weber to adapt the stereo graphic projection of a monocrystal to a poles figure. Later on, its appeared but methods to obtain the polar figure, among them, that of reflection of L. G. Schultz, but again a technique appears it specifies for its obtaining. In all the cases, the methodology is the following one: a) It is obtained by means of the diffraction process, the correspondent spectra in digitized form. b) it is applied process of having softened mathematician of the spectrum. c) there are determined the fi coordinates, beta and intensity for graph nts of the polar figure. d) Its are graph the points generated in c obtaining the polar figures.

4. Distinguished figures in descriptive geometry and its applications for mechanism science from the middle ages to the 17th century

CERN Document Server

2016-01-01

This book consists of chapters that focus specifically on single figures that worked on Descriptive Geometry and also in Mechanisms Sciences and contain biographical notes, a survey of their work and their achievements, together with a modern interpretation of their legacy. Since Vitruvius in ancient times, and with Brunelleschi in the Renaissance, the two disciplines began to share a common direction which, over the centuries, took shape through less well-known figures until the more recent times in which Gaspard Monge worked. Over the years, a gap has been created between Descriptive Geometry and Mechanism Science, which now appear to belong to different worlds. In reality, however, there is a very close relationship between the two disciplines, with a link based on extremely solid foundations. Without the theoretical foundations of Geometry it would not be possible to draw and design mechanical parts such as gears, while in Kinematics it would be less easy to design and predict the reciprocal movements of ...

5. The effect of recognizability on figure-ground processing: does it affect parsing or only figure selection?

Science.gov (United States)

Navon, David

2011-03-01

Though figure-ground assignment has been shown to be probably affected by recognizability, it appears sensible that object recognition must follow at least the earlier process of figure-ground segregation. To examine whether or not rudimentary object recognition could, counterintuitively, start even before the completion of the stage of parsing in which figure-ground segregation is done, participants were asked to respond, in a go/no-go fashion, whenever any out of 16 alternative connected patterns (that constituted familiar stimuli in the upright orientation) appeared. The white figure of the to-be-attended stimulus-target or foil-could be segregated from the white ambient ground only by means of a frame surrounding it. Such a frame was absent until the onset of target display. Then, to manipulate organizational quality, the greyness of the frame was either gradually increased from zero (in Experiment 1) or changed abruptly to a stationary level whose greyness was varied between trials (in Experiments 2 and 3). Stimulus recognizability was manipulated by orientation angle. In all three experiments the effect of recognizability was found to be considerably larger when organizational quality was minimal due to an extremely faint frame. This result is argued to be incompatible with any version of a serial thesis suggesting that processing aimed at object recognition starts only with a good enough level of organizational quality. The experiments rather provide some support to the claim, termed here "early interaction hypothesis", positing interaction between early recognition processing and preassignment parsing processes.

6. Figural medley: At the origins of XIXth Century anthropological portrait

Full Text Available During the second half of the XIXth century, Europe, the United States and Russia witnessed a blossoming interest in the use of photography in the anthropological field, its specific use was not very clear and defined yet; as a consequence, its heuristic methodologies, technical shooting modalities, stylistic elements and figurative conventions were not clear either. We range goes from anthropometric photography to an ethnographic and folkloric portrait painting signed at the same time by anthropologists and travellers, professional photographers looking for exotic subjects, amateur photographers and soldiers who encourage a figural medley characterised by scientific, commercial and artistic veins that slowly finds its definition in some of its prevailing features, in primis those of the portrait with pictorial origins, however continuously declined and reinterpreted in several ways. In this context Anthropology seeks some links with aesthetics.

We have investigated the thermoelectrical properties of chiral carbon nanotube and numerically evaluated the figure of merit. We observed that the properties are highly anisotropic and depend on the geometric chiral angle (GCA) θ h , temperature and the overlapping integrals (exchange energy) for the jumps along the tubular axis Δ z and the base helix Δ s . The thermopower α exhibited giant values with the peak occurring between 100 K and 150 K. The electron thermal conductivity showed unusually high value with the peaks shifting towards high temperature. We attribute the high peak values to electron-phonon interactions. Finally we noted that by changing the Δ s and Δ z it is possible to get a figure of merit greater than 1. (author)

8. Border-ownership-dependent tilt aftereffect in incomplete figures

Sugihara, Tadashi; Tsuji, Yoshihisa; Sakai, Ko

2007-01-01

A recent physiological finding of neural coding for border ownership (BO) that defines the direction of a figure with respect to the border has provided a possible basis for figure-ground segregation. To explore the underlying neural mechanisms of BO, we investigated stimulus configurations that activate BO circuitry through psychophysical investigation of the BO-dependent tilt aftereffect (BO-TAE). Specifically, we examined robustness of the border ownership signal by determining whether the BO-TAE is observed when gestalt factors are broken. The results showed significant BO-TAEs even when a global shape was not explicitly given due to the ambiguity of the contour, suggesting a contour-independent mechanism for BO coding.

9. Electrophysiological correlates of purely temporal figure-ground segregation.

Kandil, Farid I; Fahle, Manfred

Inhomogenous displays, in contrast to homogenous ones, evoke a specific potential in the VEP (tsVEP) which appears across different classical visual stimulus dimensions defining figure-ground segregation, such as luminance, orientation, (first-order) motion, and stereoscopic depth. This negative potential has a peak latency of about 200-300 ms and a peak amplitude of about -3 to -10 microV [Doc Ophthalmol. 95 (1998) 335]. Previously, we demonstrated that human subjects reliably segregate figure from ground, even in the absence of the classical cues, leaving time of change as the only cue for segregation. The results of the present study demonstrate that also purely temporally defined checkerboards evoke a tsVEP resembling the motion-defined tsVEP regarding polarity (negative), latency (two peaks at 180 and 270 ms, respectively), amplitude of the first negativity (-5.6 microV), and overall form of its components.

We present a complete scheme for managing the polarization of ion beams in Jefferson Lab's proposed Medium-energy Electron-Ion Collider (MEIC). It provides preservation of the ion polarization during all stages of beam acceleration and polarization control in the collider's experimental straights. We discuss characteristic features of the spin motion in accelerators with Siberian snakes and in accelerators of figure-8 shape. We propose 3D spin rotators for polarization control in the MEIC ion collider ring. We provide polarization calculations in the collider with the 3D rotator for deuteron and proton beams. The main polarization control features of the figure-8 design are summarized.

11. The Biomechanics of Cranial Forces During Figure Skating Spinning Elements.

Wang, David H; Kostyun, Regina O; Solomito, Matthew J

2015-03-01

Several facets of figure skating, such as the forces associated with jumping and landing, have been evaluated, but a comprehensive biomechanical understanding of the cranial forces associated with spinning has yet to be explored. The purpose of this case study was to quantify the cranial rotational acceleration forces generated during spinning elements. This case report was an observational, biomechanical analysis of a healthy, senior-level, female figure skating athlete who is part of an on-going study. A triaxial accelerometer recorded the gravitational forces (G) during seven different spinning elements. Our results found that the layback spin generated significant cranial force and these forces were greater than any of the other spin elements recorded. These forces led to physical findings of ruptured capillaries, dizziness, and headaches in our participant.

17. Separating figure from ground with a parallel network.

Kienker, P K; Sejnowski, T J; Hinton, G E; Schumacher, L E

1986-01-01

The differentiation of figure from ground plays an important role in the perceptual organization of visual stimuli. The rapidity with which we can discriminate the inside from the outside of a figure suggests that at least this step in the process may be performed in visual cortex by a large number of neurons in several different areas working together in parallel. We have attempted to simulate this collective computation by designing a network of simple processing units that receives two types of information: bottom-up input from the image containing the outlines of a figure, which may be incomplete, and a top-down attentional input that biases one part of the image to be the inside of the figure. No presegmentation of the image was assumed. Two methods for performing the computation were explored: gradient descent, which seeks locally optimal states, and simulated annealing, which attempts to find globally optimal states by introducing noise into the computation. For complete outlines, gradient descent was faster, but the range of input parameters leading to successful performance was very narrow. In contrast, simulated annealing was more robust: it worked over a wider range of attention parameters and a wider range of outlines, including incomplete ones. Our network model is too simplified to serve as a model of human performance, but it does demonstrate that one global property of outlines can be computed through local interactions in a parallel network. Some features of the model, such as the role of noise in escaping from nonglobal optima, may generalize to more realistic models.

18. Francis Bacon: The Real's Brutality. The Figure and the Other

Directory of Open Access Journals (Sweden)

Guido Mannucci

2014-03-01

Full Text Available Getting in front of painting by Francis Bacon touches you deeply. I’m talking about aesthetics, sensations: resounding flow that strikes abruptly, making futile any search for meaning. Francis Bacon circumvents the figurative, the meaning, he aims to the figural: to feelings, not words. Beauty, in his paintings, shows itself in the peaceful union of the positive and of its contrary; if the negative wasn’t there, though, his paintings wouldn’t exude such a brutal sense of reality. This essay investigates the figure of Francis Bacon and the spectator – the Other – as he tries to confront the painting. Bacon will be analysed using a purely phenomenological approach, with references that range from Merleau-Ponty to Martin Heidegger; the meeting-collision between the spectator and the painting, instead, will be examined taking inspiration from the Winnicott’s thesis on the relationship between Bacon and mirrors in the painter’s childhood. In order to take distance from Winnicott’s psychoanalytical approach, this essay will focus on the relationship between spectator and painting from a more anthropological point of view.

19. Figuring out’ in science and the humanities

Directory of Open Access Journals (Sweden)

Giuseppe Martella

2011-01-01

Full Text Available The purpose of this article is to enquire into the notion of change in figures of speech, concepts, topics, and technical instruments-models when they are “travelling” through different milieus, contexts, systems or disciplines. I conceive of this travelling as a basic exchange of energy/information, amounting to an event which can reshape a given field of experience. My argument is based on the premise that our experience happens at multiple levels and areas, and develops along different phases, which imperceptibly flow into each other and bear at times barely decipherable traces of the events that have constituted them. The processes happening at a different level from that of present perception can only be conceived of as infractions of the world tissue and of the related universe of discourse. Therefore in any field of enquiry the process of discovery can develop only through figures of discourse. My thesis is that, at the present stage of techno-science, Scriptural Figurality, which constitutes the basis of both Western epistemology and hermeneutics, is superseded and has to be replaced by a new hypermedial rhetoric, capable to cope with complexity, infraction and emergence, both in science and the humanities.

20. Figure-ground segregation in a recurrent network architecture.

Roelfsema, Pieter R; Lamme, Victor A F; Spekreijse, Henk; Bosch, Holger

2002-05-15

Here we propose a model of how the visual brain segregates textured scenes into figures and background. During texture segregation, locations where the properties of texture elements change abruptly are assigned to boundaries, whereas image regions that are relatively homogeneous are grouped together. Boundary detection and grouping of image regions require different connection schemes, which are accommodated in a single network architecture by implementing them in different layers. As a result, all units carry signals related to boundary detection as well as grouping of image regions, in accordance with cortical physiology. Boundaries yield an early enhancement of network responses, but at a later point, an entire figural region is grouped together, because units that respond to it are labeled with enhanced activity. The model predicts which image regions are preferentially perceived as figure or as background and reproduces the spatio-temporal profile of neuronal activity in the visual cortex during texture segregation in intact animals, as well as in animals with cortical lesions.

1. A COMPARISON OF PAIRS FIGURE SKATERS IN REPEATED JUMPS

Full Text Available Trends in pairs figure skating have shown that increasingly difficult jumps have become an essential aspect of high-level performance, especially in the latter part of a competitive program. We compared a repeated jump power index in a 60 s repeated jump test to determine the relationship of repeated jump test to competitive rank and to measure 2D hip, knee, and ankle angles and angular velocities at 0, 20, 40, and 60 s. Eighteen National Team Pairs Figure Skaters performed a 60 s repeated jump test on a large switch-mat with timing of flight and ground durations and digital video recording. Each 60-s period was divided into 6, 10-s intervals, with power indexes (W/kg calculated for each 10-s interval. Power index by 10-s interval repeated measures ANOVAs (RMANOVA showed that males exceeded females at all intervals, and the highest power index interval was during 10 to 20 s for both sexes. RMANOVAs of angles and angular velocities showed main effects for time only. Power index and jumping techniques among figure skaters showed rapid and steady declines over the test duration. Power index can predict approximately 50% of competitive rank variance, and sex differences in jumping technique were rare

2. Mitotic Figure Recognition: Agreement among Pathologists and Computerized Detector

Christopher Malon

2012-01-01

Full Text Available Despite the prognostic importance of mitotic count as one of the components of the Bloom – Richardson grade [3], several studies ([2, 9, 10] have found that pathologists’ agreement on the mitotic grade is fairly modest. Collecting a set of more than 4,200 candidate mitotic figures, we evaluate pathologists' agreement on individual figures, and train a computerized system for mitosis detection, comparing its performance to the classifications of three pathologists. The system’s and the pathologists’ classifications are based on evaluation of digital micrographs of hematoxylin and eosin stained breast tissue. On figures where the majority of pathologists agree on a classification, we compare the performance of the trained system to that of the individual pathologists. We find that the level of agreement of the pathologists ranges from slight to moderate, with strong biases, and that the system performs competitively in rating the ground truth set. This study is a step towards automatic mitosis count to accelerate a pathologist's work and improve reproducibility.

A summary is presented of the many investigations that have been done on solid residues of atmospheric fluid bed combustion (AFBC). These residues are bed ash, cyclone ash and bag filter ash. Physical and chemical properties are discussed and then the various uses of residues (in fillers, bricks, gravel, and for recovery of aluminium) are summarised. Toxicological properties of fly ash and stack ash are discussed as are risks of pneumoconiosis for workers handling fly ash, and contamination of water by ashes. On the basis of present information it is concluded that risks to public health from exposure to emissions of coal fly ash from AFBC appear small or negligible as are health risk to workers in the coal fly ash processing industry. 35 refs., 5 figs., 12 tabs

5. Figure-ground representation and its decay in primary visual cortex.

Science.gov (United States)

Strother, Lars; Lavell, Cheryl; Vilis, Tutis

2012-04-01

We used fMRI to study figure-ground representation and its decay in primary visual cortex (V1). Human observers viewed a motion-defined figure that gradually became camouflaged by a cluttered background after it stopped moving. V1 showed positive fMRI responses corresponding to the moving figure and negative fMRI responses corresponding to the static background. This positive-negative delineation of V1 "figure" and "background" fMRI responses defined a retinotopically organized figure-ground representation that persisted after the figure stopped moving but eventually decayed. The temporal dynamics of V1 "figure" and "background" fMRI responses differed substantially. Positive "figure" responses continued to increase for several seconds after the figure stopped moving and remained elevated after the figure had disappeared. We propose that the sustained positive V1 "figure" fMRI responses reflected both persistent figure-ground representation and sustained attention to the location of the figure after its disappearance, as did subjects' reports of persistence. The decreasing "background" fMRI responses were relatively shorter-lived and less biased by spatial attention. Our results show that the transition from a vivid figure-ground percept to its disappearance corresponds to the concurrent decay of figure enhancement and background suppression in V1, both of which play a role in form-based perceptual memory.

6. Vacuum-Flex Figuring of Primary Telescope Mirrors

Science.gov (United States)

Albin, E. F. M.

2004-12-01

In the current investigation, details on the construction and performance of a vacuum-flexed (i.e., figured) 51 cm (20-inch) mirror, with a fast f/4 focal ratio, are presented. A vacuum has the chief advantage of being able to pull with a uniform or isotropic stress across a large surface area, which will naturally form a parabolic surface. The essence of the idea is to grind and polish a spherical mirror and then warp or flex it into a near perfect paraboloid, thus avoiding tedious figuring altogether. To date, telescope makers around the globe have experimented with small flexed mirrors with considerable success. In these instances, mirrors have been flexed by exerting tension on a bolt or sponge-pad adhered to the back of the mirror. The prototype mirror consists of two 51 cm disks of plate glass -- each slumped to an f/4 focal ratio. The front-plate (19 mm in thickness) is separated from the back-plate (13 mm in thickness) back a flexible 9.5 mm air filled gasket. Although the rubber gasket makes a fairly good vacuum seal, silicon cement was placed about the outer edge in order to produce a perfectly tight seal. A vacuum of 8 kPa on the back of the mirror resulted in approximately 164 kilograms of negative pressure, which is required to flex the mirror into the required paraboloid. Ronchi test show a nice smooth paraboloid free from astigmatism while foucault zonal measurements display a figure better than 1/20 wave. Preliminary star testing show promising results as well. Vacuum-flexed mirrors may have benefits for both amateur and professional telescope makers alike. A US patent is pending on the aforementioned design.

7. Mechanisms of time-based figure-ground segregation.

Science.gov (United States)

Kandil, Farid I; Fahle, Manfred

2003-11-01

Figure-ground segregation can rely on purely temporal information, that is, on short temporal delays between positional changes of elements in figure and ground (Kandil, F.I. & Fahle, M. (2001) Eur. J. Neurosci., 13, 2004-2008). Here, we investigate the underlying mechanisms by measuring temporal segregation thresholds for various kinds of motion cues. Segregation can rely on monocular first-order motion (based on luminance modulation) and second-order motion cues (contrast modulation) with a high temporal resolution of approximately 20 ms. The mechanism can also use isoluminant motion with a reduced temporal resolution of 60 ms. Figure-ground segregation can be achieved even at presentation frequencies too high for human subjects to inspect successive frames individually. In contrast, when stimuli are presented dichoptically, i.e. separately to both eyes, subjects are unable to perceive any segregation, irrespective of temporal frequency. We propose that segregation in these displays is detected by a mechanism consisting of at least two stages. On the first level, standard motion or flicker detectors signal local positional changes (flips). On the second level, a segregation mechanism combines the local activities of the low-level detectors with high temporal precision. Our findings suggest that the segregation mechanism can rely on monocular detectors but not on binocular mechanisms. Moreover, the results oppose the idea that segregation in these displays is achieved by motion detectors of a higher order (motion-from-motion), but favour mechanisms sensitive to short temporal delays even without activation of higher-order motion detectors.

This expanded second edition presents in one text the concepts and processes covered in statics and mechanics of materials curricula following a systematic, topically integrated approach. Building on the novel pedagogy of fusing concepts covered in traditional undergraduate courses in rigid-body statics and deformable body mechanics, rather than simply grafting them together, this new edition develops further the authors’ very original treatment of solid mechanics with additional figures, an elaboration on selected solved problems, and additional text as well as a new subsection on viscoelasticity in response to students’ feedback. Introduction to Solid Mechanics: An Integrated Approach, Second Edition, offers a holistic treatment of the depth and breadth of solid mechanics and the inter-relationships of its underlying concepts. Proceeding from first principles to applications, the book stands as a whole greater than the sum of its parts.  .

The switching of the magnetic configuration of giant magnetoresistance multilayers not only changes the electrical and thermal conductivities but also the thermopower. We study the magnetotransport and the magnetothermoelectric properties of Co/Cu multilayer devices in a lateral thermal gradient. The Seebeck coefficient reaches values up to −18 μV/K at room temperature and shows a magnetic field dependence up to 28.6% upon spin reversal. In combination with thermal conductivity data of the same Co/Cu stack, we find a magnetothermoelectric figure of merit of up to 65%. Furthermore, a magneto-power factor of up to 110% is derived.

11. Reversing the attention effect in figure-ground perception.

Science.gov (United States)

Huang, Liqiang; Pashler, Harold

2009-10-01

Human visual perception is sometimes ambiguous, switching between different perceptual structures, and shifts of attention sometimes favor one perceptual structure over another. It has been proposed that, in figure-ground segmentation, attention to certain regions tends to cause those regions to be perceived as closer to the observer. Here, we show that this attention effect can be reversed under certain conditions. To account for these phenomena, we propose an alternative principle: The visual system chooses the interpretation that maximizes simplicity of the attended regions.

Full Text Available This paper describes the steps taken to eliminate two of the items in a Test of Figural Analogies (TFA. The main guidelines of psychometric analysis concerning Classical Test Theory (CTT and Item Response Theory (IRT are explained. The item elimination process was based on both the study of the CTT difficulty and discrimination index, and the unidimensionality analysis. The a, b, and c parameters of the Three Parameter Logistic Model of IRT were also considered for this purpose, as well as the assessment of each item fitting this model. The unfavourable characteristics of a group of TFA items are detailed, and decisions leading to their possible elimination are discussed.

18. Texture segregation, surface representation and figure-ground separation.

Grossberg, S; Pessoa, L

1998-09-01

A widespread view is that most texture segregation can be accounted for by differences in the spatial frequency content of texture regions. Evidence from both psychophysical and physiological studies indicate, however, that beyond these early filtering stages, there are stages of 3-D boundary segmentation and surface representation that are used to segregate textures. Chromatic segregation of element-arrangement patterns--as studied by Beck and colleagues--cannot be completely explained by the filtering mechanisms previously employed to account for achromatic segregation. An element arrangement pattern is composed of two types of elements that are arranged differently in different image regions (e.g. vertically on top and diagonally on the bottom). FACADE theory mechanisms that have previously been used to explain data about 3-D vision and figure-ground separation are here used to simulate chromatic texture segregation data, including data with equiluminant elements on dark or light homogeneous backgrounds, or backgrounds composed of vertical and horizontal dark or light stripes, or horizontal notched stripes. These data include the fact that segregation of patterns composed of red and blue squares decreases with increasing luminance of the interspaces. Asymmetric segregation properties under 3-D viewing conditions with the equiluminant elements close or far are also simulated. Two key model properties are a spatial impenetrability property that inhibits boundary grouping across regions with non-collinear texture elements and a boundary-surface consistency property that uses feedback between boundary and surface representations to eliminate spurious boundary groupings and separate figures from their backgrounds.

19. Constructions of the patient in healthcare communications: six patient figures.

Science.gov (United States)

Pors, Anja Svejgaard

2016-01-01

The purpose of this paper is to examine how strategic, patient-centred communication plays a part in the discursive management of expectations posed to patients and healthcare organizations. The paper provides an analysis of four documents collected as part of an ethnographic case study regarding "The Perspective of the Patient" - a Danish Hospital's patient-centred communication programme. Mapping methods inspired by Grounded Theory are used to qualify the analysis. The paper shows that strategic patient-centred communication addresses both a care-oriented approach to the patient and deploys market perceptions of patients. Market and care is seen as co-existing organizing modes that entail expectations to the patient. In the communication programme the patient is constructed in six information-seeking patient figures: affective patient; target group patient; citizen with rights; patient as a competent resource; user as active partner; and consumer. As a result, the patient-centred communication programme renders the patient as a flexible figure able to fit organizational demands of both care orientation and market concerns. This study contributes to qualitative research in organizational health communication by combining two subfields - patient-centredness and health communication - in an empirical study of how market and care are intertwined in a patient-centred communication programme. The argument goes beyond the prevalent prescriptive approaches to patient-centredness and healthcare communication, instead providing a critical analytical perspective on strategic communication and patient-centredness and showing how expectations are posed to both patient and organization.

20. A new principle of figure-ground segregation: The accentuation.

2018-02-01

The problem of perceptual organization was studied by Gestalt psychologists in terms of figure-ground segregation. In this paper we explore a new principle of figure-ground segregation: accentuation. We demonstrate the effectiveness of accentuation relative to other Gestalt principles, and also consider it autonomous as it can agree with or oppose them. We consider three dynamic aspects of the principle, namely: attraction, accentuation and assignment. Each creature needs to attract, fascinate, seduce, draw attention (e.g., a mate or a prey animal) or distract, refuse, dissuade, discourage, repulse (e.g., a predator). Similarly, each organism needs to accentuate, highlight, stress, underline, emphasize or distract from another. Thus, accentuation assigns meaning to a visual pattern such as a coat, a plumage or a flower. False eyes (ocelli) and dots (diematic patterns) demonstrate "deceiving camouflage by accentuation" that confuses predators/preys and hides or highlights vital body parts (butterflies/flowers). They also display the deceiving appearance and exhibition of biological fitness. The same accents may serve different or even opposite goals. We conclude that accentuation improves the adaptive fitness of organisms in multifarious ways. Copyright © 2017 Elsevier Ltd. All rights reserved.

1. Surreal and Canny Selves: Photographic Figures in Claude Cahun

Directory of Open Access Journals (Sweden)

Gayle Zachmann

2003-06-01

Full Text Available In her 1975 essay, Le Rire de la méduse , Hélène Cixous enthusiastically announced that it was high time for women to enter into discourse. A full half-century earlier, Claude Cahun (1894-1954, a powerful writer and a haunting photographer and artist, was already inscribing herself, Woman, and a woman's voice in visual and verbal self-portraits, photomontages, prose texts, poetry, and aesthetic and political treatises. Cahun's uncanny interventions in both verbal and visual discourse cannily interrogate conventions of literary and pictorial representation and the constructions of self, gender and culture that they exhibit. Insistently asking readers and spectators, "What's wrong with this picture?," her carnivalesque play with the doxa and the politics of identity, destabilizes not only gender and genre norms, but the boundaries and distinctions between visual and verbal representation. Surreal and Canny Selves explores the aesthetic frameworks of writer/artist Claude Cahun. Elucidating how Cahun's questioning of her self and Surrealist representations of woman were part of a much more expansive adventure that questioned more than femininity—the manuscript moves on to trace how and what Cahun's foregrounding of figuration and, more specifically, photographic figuration, might signify for the uncanny aesthetic practices deployed in the hybrid text Aveux non avenus .

In spite of his contribution to psychiatry in 19th century Britain, Henry Maudsley remains a mysterious figure, a man mostly known for his donation to the London County Council for the building of the Maudsley Hospital and for The Maudsley Annual Lecture created in honour of his benevolence. Besides Sir Aubrey Lewis' article in 1951 and Michael Collie's attempt in 1988 to construct a biographical study on Maudsley, there does not seem to be any current endeavour to tell the story of his life, whereas Trevor Turner's contribution to the 2004 Oxford Dictionary of National Biography gives a somewhat scathing but unattributed account of Maudsley's personality. This essay attempts to explore his contributions to the Medico-Psychological Association (MPA), the current Royal College of Psychiatrists, his editorship of the Journal of Mental Health (currently named the British Journal of Psychiatry), his literary contributions and his vision for a psychiatric hospital. This essay is an attempt to demystify his figure and to explore some of the rumours and criticisms surrounding his name and the reasons why so little has been written about him. It is also a venture to unravel his complex personality and his intricate philosophy. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

After an indication of some remarkable key figures (general data, data about office building, housing, industries, renewable energies, wastes, transports, agriculture and forests, and households, indication of some French and European objectives for 2020 and 2030), and a table containing indications of some international official texts (Kyoto protocol and its amendment, European directives) and of their content and scope (bio-fuels in transports, energy efficiency, buildings, labelling and eco-design, transports, renewable energies, energy and climate, greenhouse gas emissions and adaptation, air quality, wastes), and national texts (laws, plans) regarding the same issues, this publication presents figures and data under the form of graphs and tables to illustrate their evolution. They are general data on energy consumptions and intensities (data per sector and per country in Europe), markets and jobs related to renewable energies, certificates of energy saving, greenhouse gas emissions and climate change, regional data for France. The other chapters present large sets of graphs and tables of relevant data concerning housing buildings, office buildings, transports, industries, agriculture and forests, renewable energies and heat networks, wastes, and households. Generally, these data are presented in terms of evolution since the 1970's or the 1990's. They propose a detailed analytical point of view of the various energy and energy-related issues in these different sectors and fields

4. The Emergence of Figural Effects in the Watercolor Illusion

Science.gov (United States)

Pinna, Baingio; Penna, Maria Pietronilla

The watercolor illusion is characterized by a large-scale assimilative color spreading (coloration effect) emanating from thin colored edges. The watercolor illusion enhances the figural properties of the colored areas and imparts to the surrounding area the perceptual status of background. This work explores interactions between cortical boundary and surface processes by presenting displays and psychophysical experiments that exhibit new properties of the watercolor illusion. The watercolor illusion is investigated as supporting a new principle of figure-ground organization when pitted against principles of surroundedness, relative orientation, and Prägnanz. The work demonstrated that the watercolor illusion probes a unique combination of visual processes that set it apart from earlier Gestalt principles, and can compete successfully against them. This illusion exemplifies how long-range perceptual effects may be triggered by spatially sparse information. All the main effects are explained by the FACADE model of biological vision, which clarifies how local properties control depthful filling-in of surface lightness and color.

8. The edge complex: implicit memory for figure assignment in shape perception.

Science.gov (United States)

Peterson, Mary A; Enns, James T

2005-05-01

Viewing a stepped edge is likely to prompt the perceptual assignment of one side of the edge as figure. This study demonstrates that even a single brief glance at a novel edge gives rise to an implicit memory regarding which side was seen as figure; this edge complex enters into the figure assignment process the next time the edge is encountered, both speeding same-different judgments when the figural side is repeated and slowing these judgments when the new figural side is identical to the former ground side (Experiments 1A and 1B). These results were obtained even when the facing direction of the repeated edge was mirror reversed (Experiment 2). This study shows that implicit measures can reveal the effects of past experience on figure assignment, following a single prior exposure to a novel shape, and supports a competitive model of figure assignment in which past experience serves as one of many figural cues.

Two experiments investigated the role of spatial frequency in performance of a figure/ground segregation task based on temporal cues. Figure orientation was much easier to judge when figure and ground portions of the target were defined exclusively by random texture composed entirely of high spatial frequencies. When target components were defined by low spatial frequencies only, the task was nearly impossible except with long temporal delay between figure and ground. These results are incons...

Full Text Available Waray children are â€œunconsciously shifting from their mother language to English and/or Tagalog in their vocabulary useâ€. English vocabularies are more familiar to Waray educands of today than are the indigenous Waray terms, for instance, for geometrical figures, colors, numbers, etc. Still, â€œit is an ongoing debate of what type of language should be used in the implementation of MTBMLE.â€ Should educators use a Waray that borrows heavily from English and other languages or a Waray that uses exclusively its own indigenous terms and concepts? The researchers formulate a single lesson plan using an inductive method incorporating the Montessori Approach. We have two types of pupils at LNU-ILS: Waray pupils whose language at home is Waray, and Waray pupils who are exposed to English at home.

12. Optimization principles and the figure of merit for triboelectric generators.

Peng, Jun; Kang, Stephen Dongmin; Snyder, G Jeffrey

2017-12-01

Energy harvesting with triboelectric nanogenerators is a burgeoning field, with a growing portfolio of creative application schemes attracting much interest. Although power generation capabilities and its optimization are one of the most important subjects, a satisfactory elemental model that illustrates the basic principles and sets the optimization guideline remains elusive. We use a simple model to clarify how the energy generation mechanism is electrostatic induction but with a time-varying character that makes the optimal matching for power generation more restrictive. By combining multiple parameters into dimensionless variables, we pinpoint the optimum condition with only two independent parameters, leading to predictions of the maximum limit of power density, which allows us to derive the triboelectric material and device figure of merit. We reveal the importance of optimizing device capacitance, not only load resistance, and minimizing the impact of parasitic capacitance. Optimized capacitances can lead to an overall increase in power density of more than 10 times.

14. Unheimlich. From Wax Figures to the Uncanny Valley

Directory of Open Access Journals (Sweden)

Pietro Conte

2012-01-01

Full Text Available In his pioneering History of Portraiture in Wax, Julius von Schlosser traced back the age-old history of a material which at that time seemed to be already antiquated, if not obsolete. Wax sculptures were rejected and ousted from art history because of their excessive similarity and adherence to models. One hundred years later, however, hyperrealism got its revenge with Maurizio Cattelan’s celebrated hanging children. Moving from that controversial artwork and focusing on the heated polemics over it, my paper will address the question of the well-known Unheimlichkeit of wax figures, investigated by Ernst Jentsch and Sigmund Freud in the early Twentieth Century and nowadays becoming increasingly topical thanks to the recent debate about the existence and nature of the so called Uncanny Valley.

15. The Human Figure and Urban Ground: Cyborgs and the City.

Science.gov (United States)

Parkhurst, Aaron

2016-07-01

Recent years have seen developments in cyborgian movements in which people play and experiment with the boundaries of human flesh and aesthetic realities. Some individuals develop novel intimate relationships with devices that, each in their own way, interfere with human subjectivity. Public dissemination of these movements often proposes notions of transcendence, therapy, post-humanism and trans-humanism, but often fails to outline the lived-experience of those who explore cyborgian identity as an alternative mode of being in the world. This paper briefly follows self-described cyborgs who delimit the body through sensory 'enhancement' in an effort to disrupt common relationships between the human figure and the urban ground. Borrowing from Lewis Mumford's concepts of biotechnics, I propose cyborgian engagement as a type of psychodynamic living. Rather than focus on post-human discourses, these cyborgs turn to the natural world for inspiration in shaping the terms of engagement between their bodies and the city.

Sullivan, Regina M

2017-01-01

Altricial infants (i.e., requiring parental care for survival), such as humans and rats, form an attachment to their caregiver and receive the nurturing and protections needed for survival. Learning has a strong role in attachment, as is illustrated by strong attachment formed to non-biological caregivers of either sex. Here we summarize and integrate results from animal and human infant attachment research that highlights the important role of social buffering (social presence) of the stress response by the attachment figure and its effect on infant processing of threat and fear through modulation of the amygdala. Indeed, this work suggests the caregiver switches off amygdala function in rodents, although recent human research suggests a similar process in humans and nonhuman primates. This cross-species analysis helps provide insight and unique understanding of attachment and its role in the neurobiology of infant behavior within attachment.

The public is unreasonably concerned and anxious about ionizing radiation. This undefined, irrational, but still real fear of something you know is there even if you cannot perceive it with your five senses is one of the greatest problems the nuclear industry has to attack today. The major problem in this case may be the technical language used by experts. The man in the street has no idea of the technical terms experts use. However, it is possible to make our message clear without the use of any units or figures. A lot can be done for the understanding and confidence by making comparisons to familiar concepts and situations, by taking off our doctors' coats and stepping down to the grass-root level to talk with people in their own everyday language.

In order to decrease the minimum detectable activities (MDAs) of beta-gamma radioxenon detectors, it is important to increase the ability to resolve the individual isotopes. One proposed method for doing this is to increase the energy resolution of the beta cell through the use of silicon detectors. While silicon detectors can improve the energy resolution, it is accompanied with a decrease in detection efficiency compared to plastic scintillator beta cells. Due to the uncertainty on the impact of the competing variables, we have developed a figure-of-merit (FOM) capable of determining the impact of detector parameters on the MDAs. By utilizing the FOM to analyze different detectors, we are able to directly compare current and future detectors and estimate their impact on the radioxenon MDAs.

Park, Lora E; Kondrak, Cheryl L; Ward, Deborah E; Streamer, Lindsey

2018-03-01

People often search for cues in the environment to determine whether or not they will be judged or treated negatively based on their social identities. Accordingly, feedback from gatekeepers-members of majority groups who hold authority and power in a field-may be an especially important cue for those at risk of experiencing social identity threat, such as women in math settings. Across a series of studies, women who received positive ("Good job!") versus objective (score only) feedback from a male (vs. female) authority figure in math reported greater confidence; belonging; self-efficacy; more favorable Science, Technology, Engineering, and Mathematics (STEM) attitudes/identification/interest; and greater implicit identification with math. Men were affected only by the type of math feedback they received, not by the source of feedback. A meta-analysis across studies confirmed results. Together, these findings suggest that positive feedback from gatekeepers is an important situational cue that can improve the outcomes of negatively stereotyped groups.

Most metal mirrors currently used in synchrotron radiation (SR) beam lines to reflect soft x-rays are made of electroless nickel plate on an aluminum substrate. This material combination has allowed optical designers to incorporate exotic cylindrical aspheres into grazing incidence x-ray beam-handling systems by taking advantage of single-point diamond machining techniques. But the promise of high-quality electroless nickel surfaces has generally exceeded the performance. We will examine the evolution of electroless nickel surfaces through a study of the quality of mirrors delivered for use at the National Synchrotron Light Source over the past seven years. We have developed techniques to assess surface quality based on the measurement of surface roughness and figure errors with optical profiling instruments. It is instructive to see how the quality of the surface is related to the complexity of the machine operations required to produce it

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

2016-01-01

In some applications, like those for particle accelerators and transfer lines, electromagnet loads operate in cycling mode i.e. absorbing or extracting energy from or to a power source. Built-in energy storage such as electrochemical capacitors can be used whose lifetime is heavily depended on the current ripple and depth of discharge. Moreover, the sizing of this storage element is a trade-off between power taken from the grid and energy stored. Additionally, the adopted power conversion structure and control strategy impact on such decision process. In this work, a number of topologies have been evaluated for these applications and the key metrics used to compare them. The proposed figures of merit are used through examples to highlight the trade-offs related with the choice of dc-bus regulation topology and control strategy.

12. Two critical periods in early visual cortex during figure-ground segregation.

2012-11-01

The ability to distinguish a figure from its background is crucial for visual perception. To date, it remains unresolved where and how in the visual system different stages of figure-ground segregation emerge. Neural correlates of figure border detection have consistently been found in early visual cortex (V1/V2). However, areas V1/V2 have also been frequently associated with later stages of figure-ground segregation (such as border ownership or surface segregation). To causally link activity in early visual cortex to different stages of figure-ground segregation, we briefly disrupted activity in areas V1/V2 at various moments in time using transcranial magnetic stimulation (TMS). Prior to stimulation we presented stimuli that made it possible to differentiate between figure border detection and surface segregation. We concurrently recorded electroencephalographic (EEG) signals to examine how neural correlates of figure-ground segregation were affected by TMS. Results show that disruption of V1/V2 in an early time window (96-119 msec) affected detection of figure stimuli and affected neural correlates of figure border detection, border ownership, and surface segregation. TMS applied in a relatively late time window (236-259 msec) selectively deteriorated performance associated with surface segregation. We conclude that areas V1/V2 are not only essential in an early stage of figure-ground segregation when figure borders are detected, but subsequently causally contribute to more sophisticated stages of figure-ground segregation such as surface segregation.

Waste is unwanted or useless materials from households, industry, agriculture, hospitals. Waste materials in solid state are classified as solid waste. Increasing of the amount of solid waste and the pressure what it has on the environment, impose the need to introduce sustainable solid waste management. Advanced sustainable solid waste management involves several activities at a higher level of final disposal of the waste management hierarchy. Minimal use of material and energy resources ...

17. Phase transition enhanced thermoelectric figure-of-merit in copper chalcogenides

Directory of Open Access Journals (Sweden)

David R. Brown

2013-11-01

Full Text Available While thermoelectric materials can be used for solid state cooling, waste heat recovery, and solar electricity generation, low values of the thermoelectric figure of merit, zT, have led to an efficiency too low for widespread use. Thermoelectric effects are characterized by the Seebeck coefficient or thermopower, which is related to the entropy associated with charge transport. For example, coupling spin entropy with the presence of charge carriers has enabled the enhancement of zT in cobalt oxides. We demonstrate that the coupling of a continuous phase transition to carrier transport in Cu2Se over a broad (360–410 K temperature range results in a dramatic peak in thermopower, an increase in phonon and electron scattering, and a corresponding doubling of zT (to 0.7 at 406 K, and a similar but larger increase over a wider temperature range in the zT of Cu1.97Ag.03Se (almost 1.0 at 400 K. The use of structural entropy for enhanced thermopower could lead to new engineering approaches for thermoelectric materials with high zT and new green applications for thermoelectrics.

18. Maximizing percentage depletion in solid minerals

1982-01-01

This article develops a strategy for maximizing percentage depletion deductions when extracting uranium or other solid minerals. The goal is to avoid losing percentage depletion deductions by staying below the 50% limitation on taxable income from the property. The article is divided into two major sections. The first section is comprised of depletion calculations that illustrate the problem and corresponding solutions. The last section deals with the feasibility of applying the strategy and complying with the Internal Revenue Code and appropriate regulations. Three separate strategies or appropriate situations are developed and illustrated. 13 references, 3 figures, 7 tables

The role which neutron scattering can play in determining the nature of the disorder and the conducting mechanism in the solid electrolytes is discussed. First, some of the general formalism for elastic and inelastic neutron scattering is reviewed, and the quantities which can be measured are pointed out. Then the application of neutron scattering to the studies of three different problems is examined; the anion disorder in the fluorite system, the dynamical behavior in beta-alumina, and the cation diffusion in αAgI are discussed. 8 figures

1. Feedback enhances feedforward figure-ground segmentation by changing firing mode.

Supèr, Hans; Romeo, August

2011-01-01

In the visual cortex, feedback projections are conjectured to be crucial in figure-ground segregation. However, the precise function of feedback herein is unclear. Here we tested a hypothetical model of reentrant feedback. We used a previous developed 2-layered feedforward spiking network that is able to segregate figure from ground and included feedback connections. Our computer model data show that without feedback, neurons respond with regular low-frequency (∼9 Hz) bursting to a figure-ground stimulus. After including feedback the firing pattern changed into a regular (tonic) spiking pattern. In this state, we found an extra enhancement of figure responses and a further suppression of background responses resulting in a stronger figure-ground signal. Such push-pull effect was confirmed by comparing the figure-ground responses with the responses to a homogenous texture. We propose that feedback controls figure-ground segregation by influencing the neural firing patterns of feedforward projecting neurons.

2010-09-01

Unilateral spatial neglect is a disorder of attention and spatial representation, in which early visual processes such as figure-ground segmentation have been assumed to be largely intact. There is evidence, however, that the spatial attention bias underlying neglect can bias the segmentation of a figural region from its background. Relatively few studies have explicitly examined the effect of spatial neglect on processing the figures that result from such scene segmentation. Here, we show that a neglect patient's bias in figure-ground segmentation directly influences his conscious recognition of these figures. By varying the relative salience of figural and background regions in static, two-dimensional displays, we show that competition between elements in such displays can modulate a neglect patient's ability to recognise parsed figures in a scene. The findings provide insight into the interaction between scene segmentation, explicit object recognition, and attention.

In this study we sought to determine whether infants, like adults, utilize previous experience to guide figure/ground processing. After familiarization to a shape, 5-month-olds preferentially attended to the side of an ambiguous figure/ground test stimulus corresponding to that shape, suggesting that they were viewing that portion as the figure. Infants' failure to exhibit this preference in a control condition in which both sides of the test stimulus were displayed as figures indicated that the results in the experimental condition were not due to a preference between two figure shapes. These findings demonstrate for the first time that figure/ground processing in infancy is sensitive to top-down influence. Thus, a critical aspect of figure/ground processing is functional early in life.

Previously we proposed an eccentric figure-eight coil that can cause threshold stimulation in the brain at lower driving currents. In this study, we performed numerical simulations and magnetic stimulations to healthy subjects for evaluating the advantages of the eccentric coil. The simulations were performed using a simplified spherical brain model and a realistic human brain model. We found that the eccentric coil required a driving current intensity of approximately 18% less than that required by the concentric coil to cause comparable eddy current densities within the brain. The eddy current localization of the eccentric coil was slightly higher than that of the concentric coil. A prototype eccentric coil was designed and fabricated. Instead of winding a wire around a bobbin, we cut eccentric-spiral slits on the insulator cases, and a wire was woven through the slits. The coils were used to deliver magnetic stimulation to healthy subjects; among our results, we found that the current slew rate corresponding to motor threshold values for the concentric and eccentric coils were 86 and 78 A/µs, respectively. The results indicate that the eccentric coil consistently requires a lower driving current to reach the motor threshold than the concentric coil. Future development of compact magnetic stimulators will enable the treatment of some intractable neurological diseases at home. © 2014 Wiley Periodicals, Inc.

In 2 studies, children ages 3 to 7 years were asked to recall a series of touches that occurred during a previous staged event. The recall interview took place 1 week after the event in Study 1 and immediately after the event in Study 2. Each recall interview had 2 sections: In 1 section, children were given human figure drawings (HFDs) and were asked to show where the touching took place; in the other section, the same questions were asked without the HFDs (verbal condition). Children were randomly assigned to 2 different conditions: HFD 1st/verbal 2nd or verbal 1st/HFD 2nd. There were 2 major findings. First, HFDs elicited more errors than the verbal condition when used to probe for information that the child had already been asked. Second, regardless of interview method, children had poor recall of the touches even when these occurred minutes before the interview. It is suggested that cognitive mechanisms involving memory and semantics underlie children's poor recall of touching in both verbal and HFD conditions. Copyright 2009 APA

9. Figurative Idiomatic Language: Strategies and Difficulties of Understanding English Idioms

Full Text Available Learning idioms which is considered a very essential part of learning and using language (Sridhar and Karunakaran, 2013 has recently attracted a great attention of English learning researchers particularly the assessment of how well Asian language learners acquire and use idioms in communication (Tran, 2013. Understanding and using them fluently could be viewed as a sign towards language proficiency as they could be an effective way to give students better conditions to enhance their communication skills in the daily context (Beloussova, 2015. Investigating how idiomatic expressions are dealt with and processed in a second language or foreign language is an issue worth examining further since it may give language teachers a better idea of some of the strategies language learners use in order to interpret figurative language. Despite their importance, learning and using English idioms by Arab EFL learners have not been investigated extensively, and no research has been conducted on Jordanian students’ idiomatic competency. Thus, the researcher decided to work on these un-tackled issues in the Jordanian context. Most idioms-based investigations are the difficulties Jordanians learners of English face when translating them into Arabic (Hussein, Khanji, and Makhzoumi, 2000; Bataineh and Bataineh, 2002; Alrishan and Smadi, 2015. The analysis of the test showed students’ very poor idiomatic competence; particularly a very limited awareness of the most frequently used idioms despite their overwhelming desire to learn them. Data analysis of the questionnaire revealed the strategies students use and the problems they face in understanding and learning idioms.

10. Stereographic processing of CT figures in the hip joints

CT scan is widely used in orthopedic examinations. By three-dimentional display of the form of bone and joint, the change of form can be identified and the lesion can be located. CT figures were stereographically processed using a personal computer to display the images of the hip joints. The outlines of the bone seen on the CT film were directly traced with a digitizer, then the A/D converted coordinate data were obtained. The data for each slice were input to the personal computer. After conversion to normal coordinate and magnification, the data were filed on the floppy disc. These data were regained from the disk and made affin transformation to display the stereographic images of the hip joints. In a case of solitary bone cyst of the coxal bone, this method helped us to decide the appropriated surgical approach. For the congenital dysplasia of the hip, acetabular coverage was examined three-dimensionally and postoperative changes were assessed in the cases of shelf operation and intertrochanteric extension osteotomy. In the cases of aseptic necrosis of the femoral head, location and size of the necrotic area were clearly visualized and the appropriate surgical procedure could be decided. Moreover, it was useful to decide the degree of rotation of the femoral head in rotational osteotomy. (author) 61 refs.

Trauma prevention starts with to find out the extent of the problem and who it affects. Insight into morbidity figures is therefore necessary. To explore sex differences in traumatology and secondary medical care utilization in primary care related to age and socio-economic status (SES). Data were obtained from an academic continuous morbidity registration project in the Netherlands in the period from 1996 to 2006, in which 13,000 patients were followed in 10 successive years. Sex differences showed a male excess from childhood to 45 years and women showing almost double trauma rates in the elderly. Low SES was associated with the greatest incidence of traumas. The largest sex difference in incidence above 65 years appeared in the high SES with more traumas in women compared with men. From this age on, female morbidity in traumatology outnumbered male morbidity regardless of SES. Considering use of referrals, we found that in the age group 15-45 years men made a greater use of secondary medical care. However, the vastest gender influence in medical care utilization was noticed in the age group over 65 years, outnumbered with women. Young men and old women are the most at risk for traumatic health problems: men presenting with traumata of the skull, the tibia and ocular trauma's and women with fractures of the femur, humerus and wrist. For both men and women the greatest incidence is in the low SES. Family physicians can play a pivotal role in prevention to focus on their patients with high risks.

Full Text Available The article concerns itself with the figure of the teacher in Estonian society. We do not concentrate on the educational system as a whole, but on one specific and crucial element in this apparatus - the teacher. We begin by offering a brief historical overview of the conditions of pedagogues in the 20th century before moving on to describe the adoption of neo-liberal free market policies since the 1990s and the effects these policies had and still have on education. Our main concern is to understand the teacher as an actor in power relations; to achieve this understanding we have selected as our examples 1 surveillance techniques in school environment that have direct relations to the state and the market; and 2 the 2012 educational workers' strike that made it quite clear that the teachers have been fixed to a position of wage workers. The overall and more abstract aim of the paper is to think about the social role of the teacher in Estonia.

Detailed comparison of factors associated with abnormal approach to the prominent and with escalation from communication to approach has not hitherto been undertaken. This partially reflects the failure of individual studies to adopt compatible terminologies. This study involves a careful dissection of six public figure studies, three involving U.S. politicians, two Hollywood celebrities, and one the British Royal Family. Common findings were unearthed across six headings. Approachers were significantly more likely to exhibit serious mental illness, engage in multiple means of communication, involve multiple contacts/targets, and to incorporate into their communication requests for help. They were significantly less likely to use threatening or antagonistic language in their communications, except in those cases involving security breaches. These results emphasize the importance of integrating mental health findings and preventive measures into risk management. Approach should not be regarded as a single behavioral category and has multiple motivations. Future studies should adopt standard terminology, preferably taken from the general stalking research. © 2010 American Academy of Forensic Sciences.

Since their formation, asteroids since their formation have experienced little physical, geological or thermal evolution. Like comets they are thought to be among the most pristine remnants of the early solar system. One physical process, however, has played a major role since the ancient times: collisions. Dynamical families were produced by catastrophic collisions involving large enough energy to break the parent body. Other lines of evidence suggest that catastrophic collisions can also produce rubble-piles, i.e., loosely bound of post-collisional aggregates that re-accumulate to form a single body, and are kept together by gravity. The main objective of this work is to understand if—and under what conditions—Jacobi ellipsoids or other equilibrium figures can be obtained naturally by this way. This is done by performing numerical experiments simulating the re-accumulation process, and by performing high-angular resolution observations in order to better constrain the shape and density of the targets. It is shown that the outcomes of reaccumulation events tend to produce a rather narrow variety of possible shapes, and in some cases also binary systems.

16. Documents and detachment in the figurational sociology of sport

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available This article discusses the methodological implications of using a figurational approach to the study of Gaelic games (the Irish sports of hurling and Gaelic football and their organisation and governance from the late nineteenth century onwards. Following Norbert Elias, we argue that data generation guided by theories, and potentially modifying such theories, are essential components of research endeavours. The problem of generalisation or representativeness of historical documents can be addressed by treating documents as part of a fi guration of evidence, thereby constituting a mutually supporting network of data that serves as a scaffold or structure for theoretical and empirical findings. Based on the experience of using documents such as newspaper and referee reports of matches, and also organisational documents such as the minutes of meetings at various levels of governance, we contribute to the discussion concerning borders and boundary maintenance between history, sociology and historical sociology. While we elaborate on the Eliasian perspective on emotional detachment, and secondary involvement, when conducting research, we also note the dificulties in avoiding ‘preferred’ readings of national history given that Gaelic games have been intertwined with the narrative and project of national self-determination in Ireland. Researchers are compelled to recognise the theoretical significance of sports as a motor and symbol of emotional identifications, but must also create distance from their own national habitus in order to prioritise participation in intergenerational knowledge generation over further national myth-making.

18. A neural model of figure-ground organization.

Science.gov (United States)

Craft, Edward; Schütze, Hartmut; Niebur, Ernst; von der Heydt, Rüdiger

2007-06-01

Psychophysical studies suggest that figure-ground organization is a largely autonomous process that guides--and thus precedes--allocation of attention and object recognition. The discovery of border-ownership representation in single neurons of early visual cortex has confirmed this view. Recent theoretical studies have demonstrated that border-ownership assignment can be modeled as a process of self-organization by lateral interactions within V2 cortex. However, the mechanism proposed relies on propagation of signals through horizontal fibers, which would result in increasing delays of the border-ownership signal with increasing size of the visual stimulus, in contradiction with experimental findings. It also remains unclear how the resulting border-ownership representation would interact with attention mechanisms to guide further processing. Here we present a model of border-ownership coding based on dedicated neural circuits for contour grouping that produce border-ownership assignment and also provide handles for mechanisms of selective attention. The results are consistent with neurophysiological and psychophysical findings. The model makes predictions about the hypothetical grouping circuits and the role of feedback between cortical areas.

19. Theatre as a Figure and a Place of Cultural Memory

Directory of Open Access Journals (Sweden)

Lidija Kapushevska-Drakulevska

2014-11-01

Full Text Available Cultural memory is the starting point for studying culture. Theatre, on the other hand, is a multidimensional play with memory; it is an emblem of a certain culture, and of the overall blending of various discourses within it. Hence the relation between theatre and memory is rather complex and multifaceted. Theatre is a medium synthesising text and performance, speech and gesture (play, acting, as well as establishing direct, at least doubly articulated communication: among the actors on stage on the one hand, and between the actors and the audience on the other. They are all subjects of theatrical memory. Theatre not only uses memory in order to create the plot, develop the characters or establish communication with the audience, but also becomes a figure of memory itself: a culturally modelled, socially mandated (iconic, narrative, etc. memory image (Assman. Additionally, theatre may be considered a place of memory, as well. But theatre is not a simple mnemonic of repeating reality—it is not merely a simulacrum, but also a quotation of reality; it does not aim to copy or memorise reality, but to represent it and interpret it critically. This is particularly true of the contemporary rough theatre of brutality.

20. Figures of Merit Guiding Research on Organic Solar Cells

KAUST Repository

Kirchartz, Thomas

2018-03-02

While substantial progress in the efficiency of polymer-based solar cells was possible by optimizing the energy levels of the polymer and more recently also the acceptor molecule, further progress beyond 10% efficiency requires a number of criteria to be fulfilled simultaneously, namely, low energy-level offsets at the donor–acceptor heterojunction, low open-circuit voltage losses due to nonradiative recombination, and efficient charge transport and collection. In this feature article we discuss these criteria considering thermodynamic limits, their correlation to photocurrent and photovoltage, and effects on the fill factor. Each criterion is quantified by a figure of merit (FOM) that directly relates to device performance. To ensure a wide applicability, we focus on FOMs that are easily accessible from common experiments. We demonstrate the relevance of these FOMs by looking at the historic and recent achievements of organic solar cells. We hope that the presented FOMs are or will become a valuable tool to evaluate, monitor, and guide further development of new organic absorber materials for solar cells.

To study human figure drawing in a group of Alzheimer's disease (AD) patients and compare it with a group of patients with mild cognitive impairment (MCI) and controls. We evaluated consecutive outpatients over a one-year period. Patients were classified as affected by AD or by MCI. All patients and controls underwent a simplified version of the human-figure drawing test and MMSE. A qualitative and quantitative analysis of all human figures was obtained. 112 AD, 100 MCI patients and 104 controls were enrolled. AD patients drew human figures poor in details and globally smaller than MCI patients and controls. Human figures drawn by MCI patients are intermediate in body height between those of the AD patients and the healthy subjects. The head-to-body ratio of human figures drawn by AD patients is greater than controls and MCI patients, while the human figure size-relative-to-page space index is significantly smaller. Body height is an independent predictor of cognitive impairment correlating with its severity and with the number of the figure's details. Human figures drawn by AD patients are different from those drawn by healthy subjects and MCI patients. Human figure drawing test is a useful tool for orienting cognitive impairment's diagnosis.

4. Solid phase radioimmunoassays

International Nuclear Information System (INIS)

Wide, L.

1977-01-01

Solid phase coupled antibodies were introduced to facilitate the separation of bound and free labelled ligand in the competitive inhibition radioimmunoassay. Originally, the solid matrix used was in the form of small particles and since then a number of different matrices have been used such as very fine powder particles, gels, paper and plastic discs, magnetic particles and the inside surface of plastic tubes. The coupling of antibodies may be that of a covalent chemical binding, a strong physical adsorbtion, or an immunological binding to a solid phase coupled antigen. New principles of radioimmunoassay such as the solid phase sandwich techniques and the immunoradiometric assay were developped from the use of solid phase coupled antigens and antibodies. The solid phase sandwich techniques are reagent excess methods with a very wide applicability. Several of the different variants of solid phase techniques are suitable for automation. Advantages and disadvantages of solid phase radioimmunoassays when compared with those using soluble reagents are discussed. (orig.) [de

Full Text Available Abstract Elite adolescent figure skaters must accommodate both the physical demands of competitive training and the accelerated rate of bone growth that is associated with adolescence, in this sport that emphasizes leanness. Although, these athletes apparently have sufficient osteogenic stimuli to mitigate the effects of possible low energy availability on bone health, the extent or magnitude of bone accrual also varies with training effects, which differ among skater disciplines. Purpose We studied differences in total and regional bone mineral density in 36 nationally ranked skaters among 3 skater disciplines: single, pairs, and dancers. Methods Bone mineral density (BMD of the total body and its regions was measured by dual energy x-ray absorptiometry (DXA. Values for total body, spine, pelvis and leg were entered into a statistical mixed regression model to identify the effect of skater discipline on bone mineralization while controlling for energy, vitamin D, and calcium intake. Results The skaters had a mean body mass index of 19.8 ± 2.1 and % fat mass of 19.2 ± 5.8. After controlling for dietary intakes of energy, calcium, and vitamin D, there was a significant relationship between skater discipline and BMD (p = 0.002, with single skaters having greater BMD in the total body, legs, and pelvis than ice dancers (p  Conclusions Single and pair skaters have greater BMD than ice dancers. The osteogenic effect of physical training is most apparent in single skaters, particularly in the bone loading sites of the leg and pelvis.

10. Figures of desire and repression in the Conformist by Bertolucci

Full Text Available Il Conformista di Moravia (1951, ambientato in epoca fascista, narra la vicenda di Marcello, membro dell’OVRA ossessionato dalla necessità di sentirsi uguale agli altri. Si tratta di un romanzo a tesi che lega l’omosessualità alla repressione e al fascismo. L’operazione di riscrittura di Bertolucci (1970 potenzia la chiave freudiana: sul grande schermo, la ferrea progressione temporale e causale del romanzo è scardinata attraverso un uso spregiudicato del flashback, mentre scompare ogni accenno al fato e Marcello diventa filtro dell'intera narrazione. La psicoanalisi rappresenta la chiave di volta che regge il film, sostituendo la meccanicità progressiva del fato con la bi-logica dell’inconscio. Per tacitare la propria omosessualità – non accettata a livello sociale ma, prima di tutto, dal protagonista stesso – Marcello tenta di conformarsi in tutto e per tutto alla società e al particolare momento storico-politico. Il matrimonio e l’adesione al fascismo sono i due strumenti di questa strategia di conformismo; le figure femminili, in particolare, attraverso un gioco di duplicazioni e rispecchiamenti, ricoprono un ruolo cardine, configurandosi ora come oggetto di un desiderio reale ora invece di un desiderio mediato dalla volontà di rimozione e negazione delle pulsioni non accettabili, dei ricordi indicibili e dei sensi di colpa. Giocando con l’immagine, il montaggio e le interferenze col sonoro, Bertolucci sembra suggerire infatti significati profondi, che contrastano con la superficie del testo, e proporre una particolare declinazione della “retorica freudiana” del testo: richiamandosi all’approccio critico psicanalitico offerto da Francesco Orlando, l’intervento indaga le manifestazioni semiotico-linguistiche della formazione di compromesso fra desiderio e negazione da parte del protagonista ed analizza alcuni momenti del film che riflettono simultaneamente le due forze psichiche in contrasto.

2010-02-01

The aim of research is to study of the spirometry figures of bronchoobstructive syndrome in concomitant intestinal parasitosis. There are 81 patients aged from 5 to 61 years (male 43, female 38) were examined. The patients were divided into 2 groups: 1 group - patients treated only with bronchodilator therapy (14 patients with protozoa, 14 - with helminth, 12 - with combination of parasitosis); 2 group - patients treated with bronchodilator therapy in common with anti-parasitic therapy (14 patients with protozoa, 17 - with helminth, 10 - with combination of parasitosis). There are 22 patients with bronchoobstructive syndrome without parasites were included in control group. Functional disorders at the initial examination are not significantly distinguished between patients with protozoa, helminth, with combined parasitosis and patients without parasites. Considerable differences manifested in dynamics after treatment: only bronchodilator therapy of patients infected with parasites is not lead to sufficient increase of the indices of external respiration function, even the decreasing of the most parameters were observed in patients with helminth. The least growth of spirometric indices were observed in patients from group 1 - 2,17/ 5,09% predicted volumes (-6,81min; 10,54max), the highest growth were observed in patients from group 2 - 20,26/ 12,45% p.v. (2,77min; 43,85max). The spirographic indicators increase after treatment in the control group was more moderate in comparison with 1 and 2 groups - 5,96/ 2,97% p.v. (0,39min; 9,59max). Thus, using antiparasitic therapy in common with bronchodilator therapy in treatment of patients with intestinal parasitosis (group 2) is lead to the reliably significant positive dynamic of spirometry parameters in comparison not only to 1 group (<0,05 for many parameters) but also to control group (<0,01 for many parameters).

16. Altered figure-ground perception in monkeys with an extra-striate lesion.

2007-11-05

The visual system binds and segments the elements of an image into coherent objects and their surroundings. Recent findings demonstrate that primary visual cortex is involved in this process of figure-ground organization. In the primary visual cortex the late part of a neural response to a stimulus correlates with figure-ground segregation and perception. Such a late onset indicates an involvement of feedback projections from higher visual areas. To investigate the possible role of feedback in figure-ground perception we removed dorsal extra-striate areas of the monkey visual cortex. The findings show that figure-ground perception is reduced when the figure is presented in the lesioned hemifield and perception is normal when the figure appeared in the intact hemifield. In conclusion, our observations show the importance for recurrent processing in visual perception.

17. Feed-forward segmentation of figure-ground and assignment of border-ownership.

Full Text Available Figure-ground is the segmentation of visual information into objects and their surrounding backgrounds. Two main processes herein are boundary assignment and surface segregation, which rely on the integration of global scene information. Recurrent processing either by intrinsic horizontal connections that connect surrounding neurons or by feedback projections from higher visual areas provide such information, and are considered to be the neural substrate for figure-ground segmentation. On the contrary, a role of feedforward projections in figure-ground segmentation is unknown. To have a better understanding of a role of feedforward connections in figure-ground organization, we constructed a feedforward spiking model using a biologically plausible neuron model. By means of surround inhibition our simple 3-layered model performs figure-ground segmentation and one-sided border-ownership coding. We propose that the visual system uses feed forward suppression for figure-ground segmentation and border-ownership assignment.

19. Feedback Enhances Feedforward Figure-Ground Segmentation by Changing Firing Mode

In the visual cortex, feedback projections are conjectured to be crucial in figure-ground segregation. However, the precise function of feedback herein is unclear. Here we tested a hypothetical model of reentrant feedback. We used a previous developed 2-layered feedforwardspiking network that is able to segregate figure from ground and included feedback connections. Our computer model data show that without feedback, neurons respond with regular low-frequency (∼9 Hz) bursting to a figure-ground stimulus. After including feedback the firing pattern changed into a regular (tonic) spiking pattern. In this state, we found an extra enhancement of figure responses and a further suppression of background responses resulting in a stronger figure-ground signal. Such push-pull effect was confirmed by comparing the figure-ground responses withthe responses to a homogenous texture. We propose that feedback controlsfigure-ground segregation by influencing the neural firing patterns of feedforward projecting neurons. PMID:21738747

20. Shape recognition contributions to figure-ground reversal: which route counts?

Peterson, M A; Harvey, E M; Weidenbacher, H J

1991-11-01

Observers viewed upright and inverted versions of figure-ground stimuli, in which Gestalt variables specified that the center was figure. In upright versions, the surround was high in denotivity, in that most viewers agreed it depicted the same shape; in inverted versions, the surround was low in denotivity. The surround was maintained as figure longer and was more likely to be obtained as figure when the stimuli were upright rather than inverted. In four experiments, these effects reflected inputs to figure-ground computations from orientation-specific shape representations only. To account for these findings, a nonratiomorphic mechanism is proposed that enables shape recognition processes before figure-ground relationships are determined.

Determining whether a region belongs to the interior or exterior of a shape (figure-ground segregation) is a core competency of the primate brain, yet the underlying mechanisms are not well understood. Many models assume that figure-ground segregation occurs by assembling progressively more complex representations through feedforward connections, with feedback playing only a modulatory role. We present a dynamical model of figure-ground segregation in the primate ventral stream wherein feedba...

Liquid slurries expected under normal in-tank processing (ITP) operations are not ignitible because of their high water content. However, deposits of dry solids from the slurries are combustible and produce dense, black smoke when burned. The dry solids burn similarly to Styrofoam and more easily than sawdust. It is the opinion of fire hazard experts that a benzene vapor deflagration could ignite the dry solids. A tetraphenylborate solids fire will rapidly plug the waste tank HEPA ventilation filters due to the nature of the smoke produced. To prevent ignition and combustion of these solids, the waste tanks have been equipped with a nitrogen inerting system

2015-02-02

Figure-ground segregation is an important step in the path leading to object recognition. The visual system segregates objects ('figures') in the visual scene from their backgrounds ('ground'). Electrophysiological studies in awake-behaving monkeys have demonstrated that neurons in early visual areas increase their firing rate when responding to a figure compared to responding to the background. We hypothesized that similar changes in neural firing would take place in early visual areas of the human visual system, leading to changes in the perception of low-level visual features. In this study, we investigated whether contrast perception is affected by figure-ground assignment using stimuli similar to those in the electrophysiological studies in monkeys. We measured contrast discrimination thresholds and perceived contrast for Gabor probes placed on figures or the background and found that the perceived contrast of the probe was increased when it was placed on a figure. Furthermore, we tested how this effect compared with the well-known effect of orientation contrast on perceived contrast. We found that figure-ground assignment and orientation contrast produced changes in perceived contrast of a similar magnitude, and that they interacted. Our results demonstrate that figure-ground assignment influences perceived contrast, consistent with an effect of figure-ground assignment on activity in early visual areas of the human visual system. © 2015 ARVO.

Any polycrystalline aggregate normally has a preferred crystallographic orientation, or texture which depends on its thermal and or mechanical history. Preferred orientation is best described by means of a pole figure. A pole figure is a stereographic projection which shows the variation in pole density with pole orientation, for a selected set of crystal planes. In this work, computer programs was developed to plot pole figures. The corrected intensities are calculated and directly transmitted to the plotter. The different intensities levels are represented by different colors in the pole figure. (author)

The european Union Member states' political resolve to develop the energy potential of solid biomass has started to pay off, as in 2010 there were clear signs that growth of primary energy production had quickened pace. The output figure rose to 79.3 Mtoe in 2010, which is 8% up on 2009 and deserves comparison with the previous year's 4% rise (from 70.6 Mtoe in 2008). The trend, which was driven deeper by Europe's particularly cold winter of 2009- 2010, demonstrates that the economic downturn failed to scuttle the Member states' efforts to structure the solid biomass sector

Solid rockets are of interest to the space program because they are commonly used as boosters that provide the additional thrust needed for the space launch vehicle to escape the gravitational pull of the Earth. Larger, more advanced solid rockets allow for space launch vehicles with larger payload capacities, enabling mankind to reach new depths of space. This presentation will discuss, in detail, the history of solid rockets. The history begins with the invention and origin of the solid rocket, and then goes into the early uses and design of the solid rocket. The evolution of solid rockets is depicted by a description of how solid rockets changed and improved and how they were used throughout the 16th, 17th, 18th, and 19th centuries. Modern uses of the solid rocket include the Solid Rocket Boosters (SRBs) on the Space Shuttle and the solid rockets used on current space launch vehicles. The functions and design of the SRB and the advancements in solid rocket technology since the use of the SRB are discussed as well. Common failure modes and design difficulties are discussed as well.

The importance of solid base catalysts has come to be recognized for their environmentally benign qualities, and much significant progress has been made over the past two decades in catalytic materials and solid base-catalyzed reactions. The book is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems. Using numerous examples, the present volume describes the remarkable role solid base catalysis can play, given the ever increasing worldwide importance of "green" chemistry. The reader will obtain an overall view of solid base catalysis and gain insight into the versatility of the reactions to whic...

Generally, solid waste handling and management are performed by municipality or local authority. In most of developing countries, local authorities suffer from serious solid waste management (SWM) problems and insufficient data and strategic planning. Thus it is important to develop robust solid waste generation forecasting model. It helps to proper manage the generated solid waste and to develop future plan based on relatively accurate figures. In Malaysia, solid waste generation rate increases rapidly due to the population growth and new consumption trends that characterize the modern life style. This paper aims to develop monthly solid waste forecasting model using Autoregressive Integrated Moving Average (ARIMA), such model is applicable even though there is lack of data and will help the municipality properly establish the annual service plan. The results show that ARIMA (6,1,0) model predicts monthly municipal solid waste generation with root mean square error equals to 0.0952 and the model forecast residuals are within accepted 95% confident interval

Full Text Available The title of this study is, “An Analysis of Figurative Languages Used in Paulo Coelho’s novel Entitled “The Alchemist”. The objectives of the study are to describe the types of the figurative language found in the book and to identify the contextual meaning of the figurative language. The method used in collecting the data related to the subject of this research is documentation method because the researcher collected the data from novel. This study was conducted by collecting any relevant data and information about the topic or problem of the study from novels and internet that are available for the analysis. The data collection used the following steps: reading the novel, and then selecting the data that used the types of figurative language. While the steps to analyze the data are identifying the types of figurative language according to Leech, identifying the contextual meaning of the figurative language, and the last is interpreting the data.The result shows that there are 70 sentences that have figurative language. From all the sentences, there are 30 items or 42.9% of simile, 27 items or 38.6% of personification, 12 items or 17.1% of metaphor, and 1 item or 1.4% of hyperbole. It can be indicated that the dominant type of figurative language in the novel is simile. The author uses simile to explain circumstances, to describe the characters, to express emotion of the characters, and to make his writing more vivid and entertaining. It can be concluded that figurative language has important roles in this novel. That‘s why the author used so many sentences that have figurative language in this novel. Using figurative language makes the novel more interesting to read, and helps the readers to imagine the story, the character based on the illustration that the author has already given in the story.
