Abstract:
Abstract This essay discusses how and to what effect Weird and New Weird fiction use description in unique and genre-defining ways. Using H. P. Lovecraft’s “The Call of Cthulhu” and China Miéville’s The City & The City as examples, it shows how the Weird relegates a comparatively large part of the text to description and attempts to elicit dread as an aesthetic effect. The essay argues that the Weird breaks with the traditional use of description by employing formally realist tendencies which it defies functionally, and by combining over-description with the failure to describe, whereas the New Weird is more concise in its use of description, ties it more closely to the narrative, and is less reliant on descriptive failures. Both the Weird and the New Weird demand more active reader participation in their creation of aesthetic illusion, which they encourage through the frames they create around their descriptions, thus preparing readers for the potential of aesthetic distance in the reception process and diminishing its effect. The analysis emphasizes the potential of description to be more than a subordinate to the narrative mode and to be a central component in the formation of a text’s implied worldview.

Abstract:
The article discusses the issues regarding the essence of what the reality referring to typical childlike situations similar to sacrifice, and the ways the names and descriptions of behavior types differ from these types as per se. The description of lexical meanings via the semantic metalanguage and the description of typical linguistic and other cultural forms based on prototypes do not contradict each other, since they solve different problems. Consequently, generic descriptions of typical childlike situations comparable to sacrifice are lexical meanings of the short names of typical situations, constructed in metalanguage on the basis of an intuitive understanding of their similarity, existing as artefacts of text analysis, while the typical situations and forms of childlike behavior comparable to sacrifice are real-life objective forms of behavioral situations and biological, cultural and social predispositions to certain typical forms of behavior.

Abstract:
Abstract Aspheric surfaces, in particular rotationally invariant surfaces, can be described according to the ISO standard 10110 Part 12 as sagitta functions of the surface coordinates. Usually, such functions are standardized as a combination of conic terms and power series or orthogonal polynomials. Similar functions are applied for surface forms, which are not rotationally invariant as cylindric and toric surfaces. In the following, different forms of describing aspheric surfaces as given in the standard as well as other forms will be presented and compared in an overview, and their special features will be discussed.

Abstract:
I re-examine the starting point of the Philebus’ description of the ‘divine method’ and argue that the vexed phrase τῶν ἀεὶ λεγομένων εἶναι at 16c9 refers to sensibles only. In doing so, I especially stress the significance of the phrase τούτων οὕτω διακεκοσμημένων at 16d1. The proposed interpretation fits the rest of the description of the ‘divine method’, preserves the Forms’ unmixed nature and the consistency of the Philebus.

Abstract:
In my paper, I argue that some forms or instances of the balcony can be considered heterotopias. Drawing upon Foucault`s (1967) “heterotopology”, I approach the ways in which balconies entail multi- layered encodings of meaning in places that are both openings and also “conceal curious exclusions” (Foucault, 1967/2008, p. 21). Firstly, I review Foucault’s groundwork and several theoretical developments regarding heterotopias. Next, I use Geertz’s (1973) “thick description” in order to offer a brief account of three forms of the balcony, which could be placed within Foucault’s systematic description of heterotopias.

Abstract:
Le Lupus est une maladie systémique auto-immune complexe, caractérisée notamment par la perte de tolérance vis-à-vis d’antigènes nucléaires, qui affecte majoritairement les femmes à l’âge adulte. Cette maladie est hétérogène tant du point de vue clinique que génétique, ce qui a considérablement limité les progrès dans la compréhension de sa pathogénèse. Dans ce projet, nous avons mis à profit la technologie de séquençage de nouvelle génération de type « Whole Exome Sequencing (WES)» pour explorer la génétique du Lupus à l’échelle de familles individuelles. De plus, nous avons centré notre étude sur des formes à début pédiatrique qui sont cliniquement plus sévères que les formes adultes. Nous avons fait l’hypothèse que ce sous-groupe de patients devrait être enrichi en formes monogéniques. Nous avons ainsi inclus dans cette étude des cas familiaux de lupus ou des familles dans lesquelles il existait un patient lupique et des apparentés atteints de pathologies auto-immunes. Un séquençage WES a été réalisé dans ces familles et la validation des gènes identifiés par cette stratégie a fait l’objet de ce travail. Nous avons découvert une mutation hétérozygote gain de fonction du gène TMEM173 qui code STING, un adaptateur clé dans la signalisation de la détection des ADNs cytosoliques et la production d’interféron de type-I (IFN-I). Quatre membres de cette famille porteurs de la mutation présentent une pathologie auto-inflammatoire et auto-immune, dont un cas de Lupus, avec une expression clinique hautement variable. Une modélisation structurale in silico de la forme mutée prédisait initialement une stabilisation de la forme dimérique de STING avec pour conséquence possible une activation constitutive. En accord avec ces données, nous avons montré, en absence du ligand naturel, une activité constitutive de la forme mutée de STING exprimée dans une lignée cellulaire, ainsi qu’une localisation spontanée dans l’appareil de Golgi des fibroblastes de patients indiquant un état activé. Corrélativement, nous avons observé une concentration sérique élevée d’IFNa chez les patients ainsi qu’une signature transcriptionnelle fortement augmentée d’un panel de gènes induits par les IFN-I. A la suite de cette découverte, nous avons identifié de nouvelles mutations activatrices de STING chez des patients atteints de pathologies vasculaires et de fibroses pulmonaires sévères en relation avec un syndrome inflammatoire, et deux patients ont pu recevoir un traitement ciblant l’inhibition de la voie des IFN-I. Ce travail a permis de mettre en lumière le rôle clé de STING dans l’homéostasie du système immunitaire chez l’homme et de mieux comprendre la physiopathologie de maladies inflammatoires et auto-immunes, motivant la mise en place d’un traitement spécifique chez les patients. Au-delà de cette découverte importante pour ces malades, ce travail suggère que des variants rares et délétères permettent de décrire les causes génétiques de maladies auto-immunes dites complexes<br>Lupus is a complex systemic autoimmune disease characterized by a loss of tolerance to nuclear antigens predominantly afflicting women of childbearing age. The disease is both clinically and genetically heterogeneous and this has greatly limited progress in understanding disease pathogenesis. In this project, we utilize next generation sequencing technology such as “Whole Exome Sequencing (WES)” to explore the genetics of lupus at the level of individual families. Furthermore, we focused on a rare subgroup of lupus patients, which develop the disease in childhood and usually present with a more severe clinical phenotype compared to the adult-onset form. We hypothesized that this subgroup would be enriched for monogenic forms of the disease. Thus, we recruited several families with early-onset in the proband and at least one other familial member presenting with lupus or associated autoimmune disease. WES was performed and the validation of the gene identified by this strategy is described. We identified a familial gain of function dominant mutation in TMEM173, encoding STING, a key adaptor molecule in the cytosolic DNA sensing pathway and Type-I interferon (IFN-I) production. The four affected family members demonstrate a systemic inflammatory and autoimmune condition, including lupus, with variable clinical expression. Structural modeling initially predicted a stabilized dimerization of the mutant STING and thereby a constitutive activation. In agreement with this, we found that the STING mutant spontaneously localizes in the Golgi of patient fibroblasts, and is constitutively active in the absence of its ligand in vitro. Accordingly, we observed elevated serum interferon activity and a IFN-I signature in peripheral blood. We have also identified several other patients with activating STING mutations presenting with vascular inflammation and or pulmonary fibrosis, and two patients received a treatment targeting the IFN-I signaling pathway. This discovery highlights the key role of STING in human immune homeostasis and its implication in severe inflammatory and autoimmune diseases, leading to new and more specific therapeutical approaches. Beyond these important findings with regards to patients, this work suggests that rare deleterious variants can describe the genetic cause of autoimmune pathologies previously defined as complex diseases

Abstract:
There have been several changes in tourism in South Africa since 1994. During apartheid, black people were not allowed to become involved in important aspects of tourism, particularly at management level. However, this situation is changing and all cultures are gradually becoming engaged in th e tourism industry. The economic progress of the black community has resulted in the materialization of cultural villages, tourism projects to give rural people jobs, and an increase in township tourist attractions, heritage tours, etc. These initiatives have led to the establishment of certain types of tourism such as cultural tourism, urban tourism and community-based tourism. It could be said without hesitation, at the prescientific level, that the diversity in cultures, for one, is a major attraction of this country. Another change has been the increase in tourism from countries which have been excluded from South Africa in the past. Examples of these are African countries such as Kenya and Nigeria, as well as countries on other continents, including India, Bangladesh and the East-European bloc. Up to 2003/4, South Africa experienced the longest uninterrupted period of economic growth in its history. This resulted in people being able to afford a higher standard of living and therefore having more money to spend on travelling. as the economic growth stimulated the growth of tourism, both local and foreign, in the country. Seen from the perspective of the tourism industry, it is important to keep the public informed and up to date about what a country has to offer in order to maintain the increase in tourism. The media assist in this process. The travelling public is informed by word of mouth, but also through newspapers, magazines, television and radio. Information about the different attractions, whether cultures, wildlife or sport, et cetera, would not always be easy to find, were it not for the media. As tourism grows, more tourist attractions will develop, with a bigger need for tourists to be informed as an immediate result. The role of the media in this information giving is th erefore constantly on the increase.

Full text
Abstract:
Ce travail se propose d’interroger les racines de la phénoménologie husserlienne en tentant de reconstruire, sur un mode à la fois historique et systématique, le dispositif qui avait permis à Husserl de poser, dans le texte fondateur de la phénoménologie – les Recherches Logiques de 1901 – les conditions d’une philosophie rigoureusement descriptive. La description phénoménologique se déploie sur le fond d’une opposition entre deux modalités intentionnelles fondamentalement distinctes et qui doivent toutes les deux être mises à contribution dans l’activité descriptive : l’intuition d’un côté, et la signification de l’autre. Décrire, au sens large, suppose qu’un certain accord puisse être établi entre le discours et la perception dont il prétend rendre compte, entre le dire et le voir. Or, c’est à l’intuition catégoriale qu’il reviendra de prendre en charge cette tension entre signification et intuition que Husserl maintient tout au long des Recherches, en organisant les modalités d’une mise en adéquation de l’une et de l’autre. Telle est la raison pour laquelle l’intuition catégoriale joue un rôle si décisif dans l’architecture d’ensemble de ce texte : elle ne constitue pas seulement la pointe extrême de la description phénoménologique, mais elle en est en quelque sorte aussi la condition de possibilité, devant garantir la légitimité du discours philosophique à l’intérieur duquel elle se déploie. Il était ainsi possible de proposer une relecture d’ensemble des Recherches Logiques en suivant l’hypothèse selon laquelle la réforme husserlienne de la théorie des catégories devait fournir la clé d’intelligibilité et rendre compte de la spécificité de ce premier état de la phénoménologie<br>The purpose of this work is to investigate the roots of phenomenology and to analyse, from a historical and systematic point of view, the reasons that enabled Husserl to set down in his Logical Investigations the conditions of a strictly descriptive philosophy. The phenomenological description is grounded upon the opposition between two fundamentally different modalities of intentionality that both take part in descriptive activity: intuition on the one hand and signification on the other. Describing presupposes the possibility of a certain kind of adequacy between our speech and our perception, as the former is expected to correspond to the latter. By making this adequacy possible, ‘categorial intuition’ has to bear this tension between signification and intuition, and this is precisely the reason why this analysis of categories is so decisive in the architecture of the Logical Investigations. ‘Categorial intuition’ not only defines the end of phenomenological description, it is the condition of its own possibility, and is expected to validate our descriptive statements. And so it was possible to propose a new reading of the Logical Investigations by examining Husserl’s reform of the theory of categories and its relation to his phenomenological method of description

Abstract:
Notre travail concerne l'étude, le calcul et la simplification des squelettes d'objets 2D et 3D. Le squelette d'un objet est une figure mince, centrée dans la forme et qui en résume l'aspect. Il est utile pour la description et la reconnaissance de formes, la quantification, la mise en correspondance, etc. Dans un premier temps, nous recensons les différentes techniques de calcul du squelette. La très grande majorité d'entre elles travaille sur des images binaires avec des outils de la géométrie discrète. Or, dernièrement, une nouvelle famille de méthodes, appelées méthodes continues a vu le jour. Le squelette est approché à l'aide du graphe de Voronoï d'un échantillonnage de la frontière, et se calcule par des moyens propres à la géométrie algorithmique. Notre intérêt s'est porté sur cette nouvelle approche et les problèmes qui s'y rattache. Pour commencer, nous proposons une formulation des méthodes continues à l'aide du squelette d'une union finie de sphères. En effet, nous montrons que le squelette d'une union finie de sphères se construit de façon exacte à l'aide d'éléments très simples comme des segments de droite en 2D et des polygones en 3D. La construction du squelette nécessite de pouvoir interpoler par des facettes triangulaires un ensemble de points localisés sur la frontière d'un objet. Nous proposons une méthode, fondée sur le calcul du graphe de Delaunay et dont nous montrons la convergence en 2D. Enfin, des méthodes de simplification du squelette sont présentées. Elles permettent de sélectionner les branches correspondant à des renflements significatifs de la forme et conduisent en 3D soit à des squelettes surfaciques, soit à des squelettes filiformes selon les besoins de l'utilisateur. Pour finir, nous décrivons une application qui valide notre approche, et l'illustre sur des données biologiques

Tarefas automatizadas em inspeÃÃo industrial, registro de marca, biometria e descriÃÃo de imagens utilizam atributos da forma, como os cantos, na geraÃÃo de descritores para representaÃÃo, anÃlise e reconhecimento da mesma, possibilitando ainda que estes descritores se adequem ao uso em sistemas de recuperaÃÃo. Esta tese aborda o problema da extraÃÃo de caracterÃsticas de formas planares binÃrias a partir de cantos, na proposta de um detector multiescala de cantos e sua aplicaÃÃo em um sistema CBIR. O mÃtodo de detecÃÃo de cantos proposto combina uma funÃÃo de angulaÃÃo do contorno da forma, a sua decomposiÃÃo nÃo decimada por transformada wavelet ChapÃu Mexicano e a correlaÃÃo espacial entre as escalas do sinal de angulaÃÃo decomposto. A partir dos resultados de detecÃÃo de cantos, foi realizado um experimento com o sistema CBIR proposto, em que informaÃÃes locais e globais extraÃdas dos cantos detectados da forma foram combinadas à tÃcnica DeformaÃÃo Espacial DinÃmica (do termo em inglÃs, Dynamic Space Warping), para fins de anÃlise de similaridade formas com tamanhos distintos.

Automated tasks in industrial inspection, trademark registration, biostatistics and image description use shape attributes, e.g. corners, to generate descriptors for representation, analysis and recognition; allowing those descriptors to be used in image retrieval systems. This thesis explores the problem of extracting information from binary planar shapes from corners, by proposing a multiscale corner detector and its use in a CBIR system. The proposed corner detection method combines an angulation function of the shape contour, its non-decimated decomposition using the Mexican hat wavelet and the spatial correlation among scales of the decomposed angulation signal. Using the information provided by our corner detection algorithm, we made experiments with the proposed CBIR. Local and global information extracted from the corners detected on shapes was used in a Dynamic Space Warping technique in order to analyze the similarity among shapes of different sizes. We also devised a strategy for searching and refining the multiscale parameters of the corner detector by maximizing an objective function. For performance evaluation of the proposed methodology and other techniques, we employed the Precision and Recall measures. These measures proved the good performance of our method in detecting true corners on shapes from a public image dataset with ground truth information. To assess the image retrieval experiments, we used the Bullâs eye score in three public databases. Our experiments showed our method performed well when compared to the existing approaches in the literature.

The impetus are driven by two major forces: First, the momentum originated by extensive application of computational tools to any imaginable human activity, not necessarily related to design. Second, the experience derived mainly from engineering fields, which has by-produced systems intended for computer-aided architectural design. Yet, architects complain. The magic is missing. The goals, mystified. Computerized design tools are product-oriented, not process-oriented. In Architecture, the how's are as significant as the what's. This thesis presents a computational environment for architectural design. The environment aims to overcome some critical limitations of current CAD systems. Architectural design is neither drafting, nor simulation, nor modelling. Architectural design is a process of progressive consciousness acquisition. The proposed envirorunent helps architects communicate better with their design objects. It is an environment where design worlds can be expressed and explored, where architects can manifest their preferences to approach each design problem, what instruments are to be used and how they are to be manipulated. It is intended to be a tool to design better, not directly a tool to produce better designs.<br>by Manoel Rodrigues Alves, Miguel Ruano.<br>M.S.

Abstract:
We study linear descriptor systems with rectangular variable coefficient matrices. Using local and global equivalence transformations we introduce normal and condensed forms and get sets of characteristic quantities. These quantities allow us to decide whether a linear descriptor system with variable coefficients is regularizable by derivative and/or proportional state feedback or not. Regularizable by feedback means for us that their exist a feedback which makes the closed loop system uniquely solvable for every consistent initial vector.

Abstract:
In this chapter, we detail the on-going work related to the Norwegian Sign Language Corpus and lexical database (Norwegian Signbank). In particular, we highlight the corpus’ interactional focus and discuss its implications for a description of Norwegian Sign Language grammar and lexicon. We then present an initial study that maps out the different types of fingerspelling (one type of sign-writing contact), observed in the corpus, focusing on non-lexicalized forms. Two analyses were performed to investigate whether fingerspelling is affected by sociolinguistic factors and principles of Audience Design (Bell 1984). Basing this descriptive work on data from the corpus facilitates a better understanding of how these language contact forms contribute to expressions of social identity and illustrates one way that Norwegian signers leverage their multilingualism for meaning-making in conversation.

Abstract:
AbstractThis chapter suggests that the a-narrative character of the literary list—its ties to textual over-population, paratactic prose, and excessive description—initiates what I call an “aesthetic unrest”: a restless tension that sits frustratingly unresolved. To elucidate this idea, I take up Allen Ginsberg’s 1956 poem “Howl,” a deviously restless text whose subjects are constantly caught up in continuous verbs, performing illicit acts, and living in ways that defy state-sanctioned norms of behavior. Contrary to what some scholars identify as the list’s potentially dangerous cultural function, I conclude that the constantly mobile, restless character of literary lists works to alienate readers and expose them to otherness, a dynamic that is structurally aligned with contemporary theoretical conceptions of ethics and responsibility.

Abstract:
Abstract The Los Alamos National Laboratory (New Mexico) has been operating a production-scale incineration system since 1976. Following the completion of initial testing, the system was modified over time to accept low and high caloric value liquids and slurries. Combustion testing of difficult waste forms continues for the DOE, the Environmental Protection Agency (EPA), the Army, the Navy, and private companies. Anticipation of the wide range of feed compositions prompted a selection of system materials possessing satisfactory corrosion resistance. This paper presents these design considerations, the system construction materials, description of corrosion incidents, and planned materials tests to guide future construction.

Full text
Abstract:
Abstract A riser forms the connection between the top side of an off-shore platform and a pipeline on the sea-bed. Such pipeline systems may be equipped with launch and receive facilities for cleaning and general intelligent pigging of the entire pipeline. The riser may be of different material or of heavier wall thickness, making self contained intelligent pigging of the riser difficult, less effective or cost prohibitive. Today, offshore operators are strongly committed to protect the environment and pigging and riser inspection will assist in determining the condition of the installation and the riser in particular. In this description a new approach for a detailed ultrasonic inspection of the risers only is explained, based on the application of a compact umbilical (cable, tether) operated tool. This requires that the riser is bled down and liquid filled. The inspection tool provides on-line presentation of results for immediate evaluation. The system uses straight beam ultrasonic sensors for general corrosion survey in the pipe material and a novel ToFD (“Time of Flight Diffraction”) technique for additional inspection of the circumferential weld area.

Abstract:
The gender distinction between plural adjectival paradigms of обоихъ–обѣихъ is traced back to the 18th century Russian grammars: V. E. Adodurov’s, M. V. Lomonosov’s, A. A. Barsov’s. The data of the Russian Nation-al Corpus show the interchangeability of the forms of обоихъ – обѣихъin the 18th century texts. Differentiation by gender in the Russian plural paradigms was transferred rom the Church Slavonic dual paradigms of обою – обѣю. The metalinguistic construct of grammars of the 18th centuries is preserved in the normative grammars of the mod-ern Russian language, despite the fact that the gender dif-ferentiation of adjectival forms corresponds neither to the system nor to the usus

Full text
Abstract:
We describe a new design for a haploscope. A plug-in board for a pc computer drives a pair of liquid-crystal shutter glasses in synchrony with the vertical retrace interrupt of an EGA monitor. In this manner, alternate frames are displayed independently to each eye. This format allows any stimulus that can be generated with EGA graphics to be displayed stereoscopically at 60 Hz (30 Hz for each eye). This equipment permitted us to quickly and easily perform the following experiment. Four "objects", all squares, were tested for their ability to fuse stereoscopically: (1) subjective contours that were generated with different inducing figures for each eye, (2) squares of fine texture surrounded by coarser texture with different random patterns for each eye, (3) random forms defined solely by motion, and (4) forms defined by vertical lines for one eye and horizontal lines for the other, all surrounded by random patterns of the same mean luminance. All conditions have in common the property of allowing no point-by-point luminance correlation. While there was much inter-subject variability, both overall and between conditions, the results showed that stereopsis for such objects is possible, but difficult (Ramachandran et al., Nature. 1973). Condition 4 was best, but it may have allowed some effective luminance correlation resulting from the well-known neon effect. Condition 1 was the worst, presumably because it had no physical forms to be fused.

Abstract:
The article gives a definition of the organic form as an infinite-similar and self-similar structure, which is based on the increased unity of the whole and the part - holomereological symmetry. A model of plant forms as organic forms is proposed, which are based on spherocylinders – infinite-similar cylindrical volumes joined with hemispheres at their ends. The data on the golden wurf in the metric of plant stems are presented. The cirrus leaf model in MathCad is briefly described. The problem of the organic form, the form of living organisms, is a long-discussed topic in biology, in particular, in morphology. There is a lot of empirical material relating to the description of a huge variety of biological forms. However, until now, the laws of the organic form and its specificity, in comparison with the forms of inorganic bodies, continue to raise more questions than answers. It is clear that organic forms are special, they have their own laws and types of morphogenesis. But what is the essence of these features, what is the logic of their organization, all this is still largely unclear.

Full text
Abstract:
Most vision research is based on pointwise image formation physics. People, however, require more than such local information and are strikingly insensitive to reflectance function, etc. People depend on large-scale structure to guide their perceptual interpretation; general-purpose vision seems, therefore, to require a representation capable of describing such structure. We present a representation that has proved competent to accurately describe natural and man-made forms in a succinct and psychologically natural manner. Superquadrics, a superset of traditional modeling primitives, are the basic element in this representation. These primitives are then deformed by stretching, bending, or tapering and combined using Boolean operations to recursively form new, complex primitives that may again be deformed and combined. This representation has great power and efficiency: the human body (including face and hands) requires combination of only 40 primitives, fewer than 300 bytes of information. Fractallike forms (e.g., clouds, mountains) may be described in a perceptually natural manner as the recursive sum of primitives of decreasing size. Such descriptions must be recoverable from image data, which is primarily a function of the surface's normal vector. Because the vector function describing a superquadric’s surface shape is dual to that of its surface normal we can, given only the tilt component of a few surface normals, recover the desired shape description.

Abstract:
Hundreds of paleontological sites have been located and documented in Chaco Culture National Historical Park (CHCU) since 2005, the beginning of dedicated park-based paleontological surveying at the park. A paleontological resource inventory was published for CHCU in 2019, providing a baseline for paleontological resource monitoring. A paleontological site monitoring protocol has now been prepared in order to most effectively manage and monitor the abundant Upper Cretaceous paleontological resources found here. The first part of the protocol contains supporting background information; a discussion of measurable objectives for monitoring, park programs, and management; definitions of different kinds of significant specimens and various management actions; field methods; and what to do if a new site is discovered. This is followed by descriptions of the park?s paleontological localities. CHCU is divided into twelve Paleontological Management Areas (PMAs). Apart from two PMAs representing park outliers where no fossils have been reported, each PMA includes several paleontological localities, which in turn contain one or more sites. Several aspects of each locality are reported, including management priority level, stratigraphy, a brief description, ease and method of access, constituent sites, and management recommendations such as recommended actions and frequency of monitoring. This is followed by a summary of localities rated as high, medium, and low priority. Images of forms for paleontology site monitoring, paleontological sites, paleontological localities, and paleontology impact reports are provided as appendices; editable versions may be obtained from the park.

Abstract:
The article is devoted to the analysis of the main forms of visualization in the media related to photo. The thematic visual concepts are described in accordance with the content of electronic media, which consider the impact of modern technologies on the development of media space. The researches of the Ukrainian and foreign educational institutions concerning the main features of modern photo is classificate. Modifications and new visual forms in the media are singled out. The main objective of the article is to study the visual concepts of modern photo and identify ideological and thematic priorities in photo projects. To achieve the main objective in the article a certain methodology were used. Due to the historical-theoretical description it was possible to substantiate the study of visual concepts. The conceptual-system method was used to study the subject of media photo projects. The main results of the research are the definition of visual concepts of photo on the example of electronic media and the identification of the main thematic features in the process of visual filling of the media space. Based on the study, we can conclude that today the information field needs quality visual content. For successful creation of visual concepts it is necessary to single out thematic features of modern photo and to carry out classifications on ideological and semantic signs. Given the rapid development of digital technologies, the topic of the scientific article we offer is relevant for scientists, journalists, media researchers, visual journalism experts and photojournalists. Modern space is filled with a large number of pictorial materials, which in most cases form specific images, patterns or stereotypes in the mind of the reader (viewer). Also important is the classification of photo used in journalistic publications. That is why there is a need to explore the content and principles of distribution of ideological priorities of photo in the media. The substantiation of scientists about the important place of photography in the modern media space and the future development of visual technologies, which already use artificial intelligence, is relevant.

Jiang, Xiaowei, and John Cherry. History and Hydraulics of Flowing Wells. The Groundwater Project, 2023. http://dx.doi.org/10.21083/cpet1503.

Full text
Abstract:
Because flowing wells are spectacular visual evidence of groundwater occurrence, they became the impetus for both qualitative and quantitative groundwater science. The pursuit of answers to fundamental questions generated by flowing wells in confined aquifers bounded by aquitards moved the science forward for more than a century until pumping became the main form of groundwater development. Since the turn of the 20th century, flowing wells in unconfined aquifers were an impetus for the paradigm shift from aquitard-bound flow to cross-formational flow driven by topography. In this book, the histories of drilling flowing wells in France, the US, Canada, and China—which led to important findings on hydraulics of flowing wells—are summarized. The occurrence of flowing wells in confined aquifers, unconfined aquifers and semi-confined aquifers are demonstrated by showing the corresponding forms of topography-driven groundwater flow from recharge to discharge areas in different aquifers. This book introduces classic models of steady-state and transient discharge rates from flowing wells without considering basinal groundwater flow fields as proposed by Dupuit (1863), Jacob and Lohman (1952), and Hantush (1959). Recent models of transient and steady-state discharge rates of flowing wells that consider basinal groundwater flow fields—which led to a clear understanding of sources of water derived in flowing wells—are also introduced. By providing a comprehensive description of flowing wells, this book is useful not only to understanding hydraulics of flowing wells, but also to understanding the history of groundwater science.

We present a general form of attribute exploration, a knowledge completion algorithm from formal concept analysis. The aim of this generalization is to extend the applicability of attribute exploration by a general description. Additionally, this may also allow for viewing different existing variants of attribute exploration as instances of a general form, as for example exploration on partial contexts.

Full text
Abstract:
Natural Resources Canada, in partnership with the Global Earthquake Model Foundation, has prepared a public Canadian Seismic Risk Model to support disaster risk reduction efforts across industry and all levels of government, and to aid in Canada's adoption of the Sendai Framework for Disaster Risk Reduction. Developing this model has involved the creation of a national exposure inventory, Canadian specific fragility and vulnerability curves, and adjustment of the Canadian Seismic Hazard Model which forms the basis for the seismic provisions of the National Building Code of Canada. Using the Global Earthquake Model Foundation's OpenQuake Engine (OQ), risk modelling is completed using both deterministic and probabilistic risk calculations, under baseline and simulated retrofit conditions. Output results are available in all settled regions of Canada, at the scale of a neighbourhood or smaller. We report on expected shaking damage to buildings, financial losses, fatalities, and other impacts such as housing disruption and the generation of debris. This paper documents the technical details of the modelling approach including a description of novel datasets in use, as well as preliminary results for a magnitude 9.0 earthquake on the Cascadia megathrust and nation-wide 500 year expected probabilistic losses. These kinds of results, such as earthquake scenario impacts, loss exceedance curves, and annual average losses, provide a quantitative base of evidence for decision making at local, regional, and national levels.

Baader, Franz, and Barbara Morawska. Matching with respect to general concept inclusions in the Description Logic EL. Technische Universität Dresden, 2014. http://dx.doi.org/10.25368/2022.205.

Full text
Abstract:
Matching concept descriptions against concept patterns was introduced as a new inference task in Description Logics (DLs) almost 20 years ago, motivated by applications in the Classic system. For the DL EL, it was shown in 2000 that the matching problem is NP-complete. It then took almost 10 years before this NP-completeness result could be extended from matching to unification in EL. The next big challenge was then to further extend these results from matching and unification without a TBox to matching and unification w.r.t. a general TBox, i.e., a finite set of general concept inclusions. For unification, we could show some partial results for general TBoxes that satisfy a certain restriction on cyclic dependencies between concepts, but the general case is still open. For matching, we solve the general case in this paper: we show that matching in EL w.r.t. general TBoxes is NP-complete by introducing a goal-oriented matching algorithm that uses non-deterministic rules to transform a given matching problem into a solved form by a polynomial number of rule applications. We also investigate some tractable variants of the matching problem.
