The aim of this study is to extend the rationale and comprehensive understanding in respect of the notion of functionality and beauty in the smart skin buildings. Smart skin in buildings plays a key role in improving building functionality, and the future lies in the use of innovative smart skin strategies. The methodology focused on the objectivity and subjectivity of human perception to assess the aesthetic value of a building's smart skin. A theoretical analysis has been conducted based on the results of the investigation model and fortified by comparing the results with the findings obtained through the opinions of experts based in AHP methodology. The study demonstrates that there is a relation between both the aesthetic value and the functionality of the smart skin of a building. The findings revealed the difference in the aesthetic evaluation between the subjective functionality and the objective functionality of the building skin. The findings contribute useful evidence for the promotion of our understanding regarding the aesthetic value of the smart skin of a building, based on its functionality.

In this paper, I focus on the role of active touch in three aspects of shape perception and discrimination studies. First an overview is given of curvature discrimination experiments. The most prominent result is that first-order stimulus information (that is, the difference in attitude or slope over the stimulus) is the dominant factor determining the curvature threshold. Secondly, I compare touch under bimanual and two-finger performance with unimanual and one-finger performance. Consistently, bimanual or two-finger performance turned out to be worse. The most likely explanation for the former finding is that a loss of accuracy during intermanual comparisons is owing to interhemispheric relay. Thirdly, I address the presence of strong after-effects after just briefly touching a shape. These after-effects have been measured and studied in various conditions (such as, static, dynamic, transfer to other hand or finger). Combination of the results of these studies leads to the insight that there are possibly different classes of after-effect: a strong after-effect, caused by immediate contact with the stimulus, that does only partially transfer to the other hand, and one much less strong after-effect, caused by moving over the stimulus for a certain period, which shows a full transfer to other fingers.

In spatial analysis applications, measuring the shape similarity of polygons is crucial for polygonal object retrieval and shape clustering. As a complex cognition process, measuring shape similarity should involve finding the difference between polygons, as objects in observation, in terms of visual perception and the differences of the regions, boundaries, and structures formed by the polygons from a mathematical point of view. In existing approaches, the shape similarity of polygons is calculated by only comparing their mathematical characteristics while not taking human perception into consideration. Aiming to solve this problem, we use the features of context and texture of polygons, since they are basic visual perception elements, to fit the cognition purpose. In this paper, we propose a contour diffusion method for the similarity measurement of polygons. By converting a polygon into a grid representation, the contour feature is represented as a multiscale statistic feature, and the region feature is transformed into condensed grid of context features. Instead of treating shape similarity as a distance between two representations of polygons, the proposed method observes similarity as a correlation between textures extracted by shape features. The experiments show that the accuracy of the proposed method is superior to that of the turning function and Fourier descriptor.

Purpose of the article. During World War II, hundreds of Ukrainian artists were at the front. The drawings they created were a powerful source of propaganda for the Soviet regime. At the same time, in the general unity of the full-scale front-line drawing the individual features of artists of great artistic skill are clearly traced. The aim of the article is to determine the circle of leading Ukrainian artists who during the Second World War were in the troops of the Workers 'and Peasants' Red Army (RSCA) and worked in the field of drawing; to study the genre, artistic and stylistic structure, as well as materials and techniques of frontal drawings; identify the features of the reproduction of space-time in the front-line drawing of Ukrainian artists. Methodology. The study is based on the principle of historicism, a combination of historical and cultural, contextual methods, art history image and stylistic and system-comparative analysis. Scientific novelty. Peculiarities of human psychology of perception were clearly manifested in the drawing of frontline artists. The compression of the time field in the drawings of frontline artists is due not only to the doctrine of socialist realism, which was based on spatial three-dimensionality, but also to the peculiarities of human perception of time and space in stressful conditions. This also explains the difference of time display in the drawings created by the artists in the conditions of the front and evacuation. Artists, whose period of study coincided with the years of the avant-garde, the introduction of formal foundations of art in educational institutions, have achieved a much deeper and broader interpretation in the drawing of temporal and spatial categories. Conclusions. Frontline sketches were pictorial diaries: notes, sketches that were intended to be triggers for memories, for further writing of pictorial "memoirs" - paintings on the theme of war. This theme of Soviet propaganda will become a pass for future decades in all artistic spheres, both artistic and literary, musical, film and theater, etc., ensuring the favor of party leaders and the respect of the average Soviet man. Drawings of Serhiy Hryhoriev, Zinovy ​​Tolkachov, Vasyl Ovchynnikov, Anatol Petrytsky, Georgy Melikhov, Anton Komashko and other prominent Ukrainian artists are distinguished by the ability to give the passage of events the meaning of epic generalization, elevation above the simplified goal of capturing the moment. Keywords: drawing, Ukrainian drawing, frontline drawing, sketch, the Second World War, portrait, landscape.

The article is devoted to the phenomenon of holographic human perception in the analysis of the architectural environment. Includes aspects of perspective-tonal perception of visual factors of holographic scanning of the human visual system. Aimed at understanding and reproducing the features and nuances of vision, in the context of summary analysis and reproduction of the system of energy flows in the elements of visual perception. The holographic factor of perception of reality is based on the difference between the work of the right and left eye, with the peculiarity of the angular adjustment of vision to the object of observation. The horizon line or the height of the perception of volumes, as well as the position of the spaces of the architectural environment remain dominant.

In the article there is defined the concept of comic as a rhetorical and semantic technique in public discourse, which exerts psychological and behavioral influences. There are highlighted the main features of the comic, in particular: the comic is available for human perception; it causes laughter among representatives of a certain social group, demonstrates the difference between different groups (motives of comedy are not global, they will be funny only for a certain people); entertains the addressee, does not cause suffering and does not activate emotions of empathy in the audience to which it is directed. A. Bergson defines the basic rule of the comic – to demonstrate the unnaturalness, inflexibility, something uncharacteristic for normal life. The philosopher describes also three additional principles of the comic: repetition (the repetition of the certain signs – verbal and nonverbal – will be funny), inversion (replacement of social roles) and interference (semantic ambiguity of a one sign).The article identifies the comic’s techniques used by Volodymyr Zelensky as a candidate for the presidency of Ukraine during the 2019 election campaign. The materials for the study are political advertising, distributed both by classic media (television and outdoor advertising) and by social media. Author states that in the materials of V. Zelensky’s political agitation are present all of three methods of the comic, described by A. Bergson.In the article is claimed that laughter is able to perform the following social functions: to stimulate the development of the community by pointing out the outdated trends, as well as to ridicule those who wants to initiate social development. Comic, widespread by political leaders, can identify areas of public discontent and at the same time create space for psychological relief by spreading a sense of indifference to the future.

The difference between average densities of the Moon and Earth was interpreted in the preceding report by Professor H. Urey as indicating a difference in their chemical composition. Therefore, Urey assumes the Moon's formation to have taken place far away from the Earth, under conditions differing substantially from the conditions of Earth's formation. In such a case, the Earth should have captured the Moon. As is admitted by Professor Urey himself, such a capture is a very improbable event. In addition, an assumption that the “lunar” dimensions were representative of protoplanetary bodies in the entire solar system encounters great difficulties.

AbstractThe oldest cell-like structures on Earth are preserved in silicified lagoonal, shallow sea or hydrothermal sediments, such as some Archean formations in Western Australia and South Africa. Previous studies concentrated on the search for organic fossils in Archean rocks. Observations of silicified bacteria (as silica minerals) are scarce for both the Precambrian and the Phanerozoic, but reports of mineral bacteria finds, in general, are increasing. The problems associated with the identification of authentic fossil bacteria and, if possible, closer identification of bacteria type can, in part, be overcome by experimental fossilisation studies. These have shown that not all bacteria fossilise in the same way and, indeed, some seem to be very resistent to fossilisation. This paper deals with a transmission electron microscope investigation of the silicification of four species of bacteria commonly found in the environment. The Gram positiveBacillus laterosporusand its spore produced a robust, durable crust upon silicification, whereas the Gram negativePseudomonas fluorescens, Ps. vesicularis, andPs. acidovoranspresented delicately preserved walls. The greater amount of peptidoglycan, containing abundant metal cation binding sites, in the cell wall of the Gram positive bacterium, probably accounts for the difference in the mode of fossilisation. The Gram positive bacteria are, therefore, probably most likely to be preserved in the terrestrial and extraterrestrial rock record.

AbstractThe interrelationship of half-widths and intensities for the red, green and yellow lines is considered. This is a direct relationship for the green and yellow line and an inverse one for the red line. The difference in the relationships of half-widths and intensities for different lines appears to be due to substantially dissimilar structuring and to a set of line-of-sight motions in ”hot“ and ”cold“ corona regions.When diagnosing the coronal plasma, one cannot neglect the filling factor - each line has such a factor of its own.
