Jarenski, Shelly. "Playing Dead: Eadweard Muybridge’s Residential Photo Albums and Spiritualist Aesthetics". Nineteenth Century Studies 35 (noviembre de 2023): 54–74. http://dx.doi.org/10.5325/ninecentstud.35.0054.
Texto completoResumen
Abstract Eadweard Muybridge, whose studies of animals in motion precipitated the first motion pictures, has been associated with positivism, modernism, and masculinity. Late nineteenth-century spiritualism has been associated with mysticism, Victorianism, and femininity. These associations make the Kate and Robert Johnson Residential Photo Album, photographed by Muybridge, a compelling artifact. The album is an anomaly in both Muybridge’s career and within spiritualism. Along with preserving images of the Johnsons’ domestic space, it also features astonishing images that are the only known examples of spirit photography by Muybridge. Because the couple was alive and took turns posing as the spirits, these photographs are an anomaly within spiritualism as well since spirit photographs generally constituted proof of contact with the netherworld. As such, the artifact helps us reevaluate the relationship between nineteenth-century positivism and spiritualism and consider the aesthetic influence of the sitter Kate Johnson on the album’s production. This article also places the album in the context of other visual culture phenomena, such as scrapbooking and album practices, as well as museum aesthetics. Finally, it considers narratives of gender, sexuality, and the nuclear family, within and beyond the album itself and the discourses surrounding spiritualism.

Texto completoResumen
A stop-frame animation system has been developed for producing high-resolution, color and stereo motion picture animation sequences. The first of these sequences can be seen in the recently released IMAX 3D movies, “Four Million House Guests” a.k.a. “The Hidden Dimension”. IMAX movies have long been known for their breathtaking special effects that seem incredibly realistic because of the large projection screen (about 7 stories high) which is close to the entire audience, high resolution, and powerful audio effects. IMAX 3D is an extention to the traditional format that allows the audience to see three dimensional special effects with the aid of electronically shuttered viewing glasses. IMAX movies are an ideal medium to demonstrate the high resolution digital images that are possible with the SEM.The goal of the SEM movie project was to produce movie sequences where viewers feels like they are flying smoothly through micro-space past microscopic creatures and objects in three dimensions and in color.

This article examines the visual dynamics underlying wrong-body narratives of gender through Lacanian psychoanalytic readings of Annie Leibovitz’s photographs of Caitlyn Jenner for Vanity Fair (2015) and Pedro Almodóvar’s film La piel que habito (Spain/France, 2011). Leibovitz’s photographs, seen as the public culmination of Jenner’s gender transition, and Almodóvar’s fictional film, centered on the forced surgical sex reassignment of one of its characters, both comment on the role of technically produced images in constructing visually articulated bodily materiality as central to gender. Staged in Jenner’s domestic space, often before mirrors that reflect the camera alongside its subject, Lei-bovitz’s photos portray Jenner at the center of complex scenarios of mastery over her image. These images demonstrate an awareness of their constructed nature at the same time as they offer themselves as the optical proof of Jenner’s transition; they reveal and, ostensibly, dominate what Lacan refers to as the fundamental misrecognition at the heart of all scopic scenarios of recognition. Almodóvar’s film imagines the reverse scenario in which the body-as-image exerts violent control over the individual, not only erasing the apparent sex of one of its characters, Vicente, but also, and less tolerably, attempting to erase the absence, or misrecognition, of his body in its status as what Lacan calls “objet a,” or object of desire. The distinct ways in which Leibovitz’s images and Almodóvar’s film theorize the relationship between bodies and images with regard to misrecognition and absence point to the continued necessity of considering the influence of scopic relations in formations of gender identity.

During the interwar period in the 1920's and 1930's, the general opinion on domestic life was that it should be run in an efficient and rational way. In her book A New Spirit in the Home, Miep van Rooy spöke about the functional use of space in the home. She explained how movements create space and depicted the activities of the housewife in such terms. It was the housewife who should decide about the use of the available space in the home and rationalise the domestic chores so that she could devote more time to her children and family. Her main duty was apparently to be at home. Guidebooks 011 home furnishing and interiör decoration can tell us a good deal about the prevailing views on lifestyle, morality and consumption. When reading Van Rooy and her contemporaries, one discovers that the women were entangled in the nets that had been knit by domestic science and well-meaning architects. The scientists and the architects based their knowledge on empirical facts about domestic life, and their descriptions of household functions were more or less impartial. Household duties could be done by anyone, they said. But they still remained with the women. The power of the prevailing home culture had thus been underestimated. The famous foundation of Goed Wonen, (Good Housing), had a more existential approach to domestic life. It is apparent in books like the guide to interiör decoration written by Cora Nicolai in the 1960's. She emphasized the various activities in the home and described family life in terms of togetherness, intimacy and perconal contact. Space was seen as stemming from and exisiting by human interaction. This is why there are people present in most of the pictures of interiörs in her book. They remind us strongly of 19th century pictures of the happy family. Father is seen reading or talking to bis friends, sometimes playing with bis son. Mother is serving tea or doing needlework, the daughter is reading a book. These pictures do not only show how family life should be, but also what activities constitute the idea of the family home. Not even the architects of Goed Wonewwere able to go beyond the traditional view on the division of work with respect to gender. In this way, the women were caged in their homes, being at the same time "place" and "movement".

Texto completoResumen
The use of film and video in sociological research, or social sciences in general, has a long and well-established tradition. Motion pictures have, on the one hand, been the object of analysis, as in the case of sociology of film, and, on the other, they have been used as a research tool. Moreover, films can be scientific statements in their own right, as is the case with sociological film.
The use of visual methods based on both still and moving pictures works very well for exploring the physical and social space of the city. The article looks at ways of using films and the actual process of obtaining film data in sociological research. Works featuring urban themes will be considered as special cases to illustrate the author’s reflections. It is noteworthy that early cinema already showed urban space, as exemplified in the films by the Lumière brothers who, incidentally, treated their motion pictures primarily as a scientific tool.
City-related topics appear in research by film sociologists who analysed films featuring urban themes, among other things. Later, sociologists themselves began to use cameras in their studies and teaching. One way of using a camera for these purposes is simply to record observations of certain places and people’s behaviour. These video recordings are subsequently analysed, applying various methods developed in the field of sociology and other sciences. Another technique, well-suited for exploring urban space, is a mobile camera, used for example for video tours, as introduced by Sarah Pink. And, finally, sociological film focusing on the city plays a vital role in social research.

This paper presents a water intake monitoring system for animal agriculture that tracks individual animal watering behavior, water quality, and water consumption. The system is deployed in an outdoor environment to reach remote areas. The proposed system integrates motion detectors, cameras, water level sensors, flow meters, Radio-Frequency Identification (RFID) systems, and water temperature sensors. The data collection and control are performed using Arduino microcontrollers with custom-designed circuit boards. The data associated with each drinking event are water consumption, water temperature, drinking duration, animal identification, and pictures. The data and pictures are automatically stored on Secure Digital (SD) cards. The prototypes are deployed in a remote grazing site located in Tucumcari, New Mexico, USA. The system can be used to perform water consumption and watering behavior studies of both domestic animals and wild animals. The current system automatically records the drinking behavior of 29 cows in a two-week duration in the remote ranch.

Abstract The formal, cinematic language specific to immersive motion pictures is an area of cinema theory that has been neglected up until now. This paper investigates a new language of cinematic montage specific to immersive cinema, somatic montage, while it examines historical precedents in the sciences, arts, and cinema of the twentieth century. We propose somatic montage as a model for developing new poetic structures in time-based works that inhabit a three-dimensional, architectonic space – a space of embodiment, motion, perception, and participation in the reception of a work of art. In this paper, we consider cinema as a four-dimensional artwork conceptually engendered by the principles of hyper-dimensions, the outgrowth of scientific discoveries made at the turn of the twentieth century. The expanded cinema mediums of fulldome cinema, immersive video and film installation, virtual reality, and extended reality, when approached as four-dimensional cinema space, allow for a spatialized, non-linear juxtaposition of the cinematic elements. Somatic montage is presented here as an extended, supra-dimensional notion of what Sergei Eisenstein called the ‘disjunctive method of narration’.

Abstract This study analyses how speakers of two typologically distinct first languages (English (N = 12) and Spanish (N = 16)) and a group of 19 Spanish second language learners of English express boundary-crossing events, what type of verb they use, and how they segment these motion events. The stimuli used were 12 pictures of boundary-crossing events indicating motion into, out of and over a bounded space. In task 1 participants described each of the 12 scenes freely and in task 2 they were provided with a specific Manner verb between brackets. Significant differences were found in boundary-crossing and event segmentation in both L1 and L2. Participants also differed significantly in the type of verb used in the two tasks.

This paper examines the cinematographic reworking of memory spaces associated with power relations and structural injustice. The way in which space is represented and used as a medium that reflects power relations allows to question the space itself in cultural productions from Central-Eastern Europe when associated with Romani people (space and power relations, memory of slavery and discrimination, space and freedom, territoriality, space and its inhabitants, non-belonging, segregation, etc.). The paper focuses on motion pictures produced in the last decade in Romania, a prolific period due to the increasing interest for memory activism and to the multiplication of the cultural exploration of challenging topics. It aims to identify narrative, visual, and aesthetic expressions used as deterritorialization practices to stimulate relational remembrance and engagement with ongoing social inequality and structural injustice. Two short films – Alina Șerban’ s Bilet de iertare (Letter of forgiveness) and Adrian Silișteanu’s Scris/Nescris (Written/Unwritten) – and a western type film – Radu Jude’s Aferim!, winner of the Silver Bear for Best director at Berlinale in 2015, are analysed here.

Texto completoResumen
The surface electromyography (sEMG) signal is widely used as a control source of the upper limb exoskeleton rehabilitation robot. However, the traditional way of controlling the exoskeleton robot by the sEMG signal requires one to specially extract and calculate for complex sEMG features. Moreover, due to the huge amount of calculation and individualized difference, the real-time control of the exoskeleton robot cannot be realized. Therefore, this paper proposes a novel method using an improved detection algorithm to recognize limb joint motion and detect joint angle based on sEMG images, aiming to obtain a high-security and fast-processing action recognition strategy. In this paper, MobileNetV2 combined the Ghost module as the feature extraction network to obtain the pretraining model. Then, the target detection network Yolo-V4 was used to estimate the six movement categories of the upper limb joints and to predict the joint movement angles. The experimental results showed that the proposed motion recognition methods were available. Every 100 pictures can be accurately identified in approximately 78 pictures, and the processing speed of every single picture on the PC side was 17.97 ms. For the train data, the mAP@0.5 could reach 82.3%, and mAP@0.5–0.95 could reach 0.42; for the verification data, the average recognition accuracy could reach 80.7%.

This paper analyses the interpretation of boundary-crossing events in second language acquisition (SLA) to determine whether L2 learners are able to select the target-like option for the interpretation of motion events or whether, on the contrary, their choice reflects cross-linguistic influence (CLI) of their L1. The two groups participating in the study – thirty Spanish learners of L2 English and sixteen English first language (L1) speakers – were subjected to an experiment involving an interpretation task with L2 boundary-crossing events pictures. Findings indicate that Spanish L2 learners selected three possible constructions (manner verb + path satellite, path in verb + manner in satellite and a combination of both) in clear contrast to English L1 speakers who only selected one construction (manner verb + path satellite). CLI has also been found to regulate the type of boundary-crossing event selected, primarily in cases of motion INTO a bounded space in the horizontal axis.

Migration of intraocular silicone oil, used in the treatment of complicated retinal detachment, has been rarely described, but when it happens it can arise with a differential diagnosis with scleral buckling extrusion, tumor, dermoid, ocular cysticercosis, and abscess. The presence of silicone oil in the eye gives very ugly echographic pictures, but these kinds of pictures can be very useful in making a differential diagnosis in the above-mentioned cases. A 39-year-old white female complained of the presence of conjunctival hyperemia and tearing in the right eye (RE); her visual acuity was hand motion, and the intraocular pressure was 14 mmHg. In the upper nasal quadrant a dome shaped lesion was detected. Due to the lens opacities, the patient underwent an echographic examination, which revealed the presence of silicon oil both in the vitreous chamber and in a large subconjunctival space, corresponding to the lesion. This article in addition provides a possible explanation of such cystic formation and discusses the risk factors and the role of the echographic examination in such cases.

Abstract The aim of this paper is to quantify tourists (both domestic and international) of Slovakia and their chronology throughout the years. Firstly, a brief development of them is introduced (absolute number and proportion of the total traffic from 1985 to 2013). Subsequently, the structure of their nationality, spatial differentiation (at municipal level) and seasonality is discussed (respective distribution during the year). The aim of this study is to discover a spatial context in space and time. To quantify the number of tourists, the data from the Statistical Office of the Slovak Republic and also from the Ministry of Transport, Construction and Regional Development, are used. These data are interpreted in analyses and confirmed by tables, graphs and pictures.

Programmed retinal picture investigation is a significant screening device for simple identification of eye infections like diabetic retinopathy, glaucoma. Hemorrhage (HE) identification is one of the significant strides in programmed extraction in Diabetic Retinopathy (DR) ailment. The manual strategy evaluated by clinicians is a tedious and asset concentrated procedure. Programmed retinal picture examination gives a prompt recognition and portrayal of retinal highlights preceding a pro investigation. Current HE detection techniques suffer from impractically-high computation time. In this research work, presented a technique to automatically detect HE. This paper proposes an efficient motion pattern generation algorithm to detect HE. The novelty of this method is to reduce the dimensional space based on image resolutions thus, enhances to speedup of the HE detection. The proposed strategy was executed in MATLAB and assessed both ordinary and unusual retinal pictures utilizing openly accessible MESSIDOR dataset. The proposed strategy accomplished better execution estimates when contrast with other cutting edge strategies. This automated method helps ophthalmologists in the screening process of DR.

Human concepts can be roughly divided into entities (prototypically referred to in language by nouns) and events (prototypically referred to in language by verbs). While much work in cognitive neuroscience has investigated how the brain represents different categories of entities, less attention has been given to the more basic distinction between entities and events. We used functional magnetic resonance imaging to examine brain activity while subjects performed a conceptual matching task that required them to access knowledge of objects and actions, using either pictures or words. Since action events involve movement through space, we hypothesized that accessing knowledge of actions would cause greater activation in brain regions involved in motion or spatial processing. In comparison to objects, accessing knowledge of actions through pictures was accompanied by increased activity bilaterally in the human MT/MST and nearby regions of the lateral temporal cortex. Accessing knowledge of actions through words activated areas just anterior and dorsal to area MT/MST on the left, within the posterior aspect of the middle and superior temporal gyri. We propose that the lateral occipital temporal cortex contains a mosaic of neural regions that processes different kinds of motion, ranging from the perception of objects moving in the world to the conception of movement implied in action verbs. The lateral occipital temporal cortex mediates the perceptual and conceptual features of action events, similar to the way that the ventral occipital temporal cortex processes the perceptual and conceptual features of entities.

Texto completoResumen
This article investigates the relevance between body representation in online performance and Islamic art by studying Domestic Tension, an online performance by Iraqi-born artist Wafaa Bilal. Bilal lives under online participant shoots, with a paintball gun, in a gallery and broadcasts the event 24/7 on the internet. Islam and its laws, related to the body, played a central role in this performance and remained out of sight. The Qur’an mentioned the body rarely in verses; therefore, the Hadith is the most trustworthy reference to learn. Based on Hadith, figural representation between Muslims is banned, and the makers of these pictures get punished in the other world. This prohibition must be the main reason for Muslim artists’ use of symbols and signs to represent figures. In the virtual space artworks, the artist kills his own body to represent the body as a basic image, codes and sings. By analysing Domestic Tension, I argue that the connection between Muslim artists’ perception of the body and the definition of semiotics body in online performance can be a reason for artists with an Islamic background to use the internet as a medium to express themselves.

Texto completoResumen
The common geometrical (symplectic) structures of classical mechanics, quantum mechanics, and classical thermodynamics are unveiled with three pictures. These cardinal theories, mainly at the non-relativistic approximation, are the cornerstones for studying chemical dynamics and chemical kinetics. Working in extended phase spaces, we show that the physical states of integrable dynamical systems are depicted by Lagrangian submanifolds embedded in phase space. Observable quantities are calculated by properly transforming the extended phase space onto a reduced space, and trajectories are integrated by solving Hamilton’s equations of motion. After defining a Riemannian metric, we can also estimate the length between two states. Local constants of motion are investigated by integrating Jacobi fields and solving the variational linear equations. Diagonalizing the symplectic fundamental matrix, eigenvalues equal to one reveal the number of constants of motion. For conservative systems, geometrical quantum mechanics has proved that solving the Schrödinger equation in extended Hilbert space, which incorporates the quantum phase, is equivalent to solving Hamilton’s equations in the projective Hilbert space. In classical thermodynamics, we take entropy and energy as canonical variables to construct the extended phase space and to represent the Lagrangian submanifold. Hamilton’s and variational equations are written and solved in the same fashion as in classical mechanics. Solvers based on high-order finite differences for numerically solving Hamilton’s, variational, and Schrödinger equations are described. Employing the Hénon–Heiles two-dimensional nonlinear model, representative results for time-dependent, quantum, and dissipative macroscopic systems are shown to illustrate concepts and methods. High-order finite-difference algorithms, despite their accuracy in low-dimensional systems, require substantial computer resources when they are applied to systems with many degrees of freedom, such as polyatomic molecules. We discuss recent research progress in employing Hamiltonian neural networks for solving Hamilton’s equations. It turns out that Hamiltonian geometry, shared with all physical theories, yields the necessary and sufficient conditions for the mutual assistance of humans and machines in deep-learning processes.

This study relates to a system for providing a metaverse platform in which the weather changes according to the situation of the stock market. In more detail, it is to be provided with information related to the stock investment and to perform economic activities within the metaverse space. Also, it relates to a system for providing a metaverse platform that allows the weather in the metaverse space to fluctuate according to the situation of the stock market so that the situation of the stock market can be understood more intuitively. The system for providing a meta-verse platform in which weather changes according to the situation of the stock market is largely composed of two parts which are a meta-verse interface and a main server. First, the metaverse interface part consists of motion, avatar, and space generator. Specifically, the motion generator generates user motion information according to a signal received through a user terminal possessed by the user. The avatar generator generates a moving avatar in association with the user motion information. The space generator generates a virtual metaverse space in which at least one avatar is displayed and displays the generated space on the user terminal. Second, the main server includes object creation, investment index identification, and weather change modules. The object creation module generates a plurality of objects to be displayed and processed on the metaverse space. The investment indicator identification module sets investment indicators including domestic stock price trends, including rising, falling, and sideways, based on the 5-day moving average for the Korean stock market comprising the KOSPI and KOSDAQ. Finally, the weather change module serves to differentially adjust the amount of precipitation for the area near the object displayed in the metaverse space according to the investment index.

We consider the features of the images’ construction in the story “The Adolescence of Luvers” by Boris Pasternak. In this regard, we turn to the analysis of individual episodes in the story, which, in our opinion, become key for revealing the theme of the main character’s growing up. The narrative itself in the poet’s prose texts is constructed in such a way that all its components are endowed with special internal dynamics, owing to which the images lose their outlines, transform, receive additional, not always decipherable meanings. We dwell on three points in detail: the collision of Zhenya Luvers with Motovilikha – the moment of the end of her infancy – and the two meetings of the heroine with Tsvetkov, an “stranger” whose figure influences Zhenya’s consciousness, her transition to growing up. In the episodes under consideration, there is a hint of an “ecphrastic mark”: the images and objects in the story seem to add up to a kind of description of the picture, although there are no direct references to pictorial or sculptural images in the story. We analyze how the similarities of the ecphrase appear in Pasternak’s text and how they transform the space of the story. The pictures appearing in the story are often enclosed in a kind of frame (visual or symbolic, for example, acoustical), they freeze for a moment, but then come back into motion. The objects that appear in these descriptions and the boundaries between them become unsteady, everything in the space of the text oscillates between static and dynamic. We dwell in detail on the analysis of images and motives that accompany the turning points for the heroine of the transition from infancy to childhood, and then to adulthood, and we come to the conclusion that they are filled with pictorial allusions, all objects are in a complex relationship: objects lose their outlines and endow internal dynamics – paintings “come to life”. Thus, we can speak of an “ecphrasis mark” that supports the internal dynamics of the text of the story “The Adolescence of Luvers”, and “reviving pictures” become an important element of the artistic world of the story by Boris Pasternak.

The use of near-Earth space is currently complicated by the presence of space debris objects in Earthʼs orbit, which include spent stages of launch vehicles, inoperative spacecraft, and other large and small objects associated with human activity in space. One of the elements of solving the problem of space debris is the docking and capture of an uncontrolled non-cooperative space object or spacecraft by a so-called on-orbit servicing spacecraft to carry out further actions to repair it, refuel or change its orbit. The situation is complicated by the fact that, under the influence of various factors, uncontrolled space objects are in a state of rotation. The parameters of the orbital motion of such objects are known quite accurately from measurements from the Earth. To carry out safe approach and docking, knowledge of the parameters of rotational motion, as well as the parameters of relative motion, is also required. The most general case of motion of a non-cooperative tumbling spacecraft located in an elliptical orbit is considered. It is assumed that the three-dimensional graphic model of such spacecraft is known. The servicing spacecraft (SSC) is equipped with a mono camera that takes pictures of the non-cooperative spacecraft (NSC). Based on a comparison of the characteristic features of photographs and images obtained using the graphical model, the computer vision system (CVS) determines the distance vector to the so-called graphical coordinate system, rigidly fixed on the NSC and the quaternion of its relative attitude. The specific type of CVS is not considered. It is assumed that the SSC carries out some maneuvers near the satellite. All parameters of the SSC angular motion are assumed to be known. This work considers the most general case of the relative motion of SSC and NSC. Using quaternion calculus, all basic kinematic and dynamic equations are obtained. The measured parameters are not enough to ensure safe rendezvous and docking with the NSC. The stochastic characteristics of errors of the CVS measurement are not assumed to be known and, accordingly, are not used. Only their maximum values are specified for them. We consider the use of new dynamic set-membership filter using ellipsoids to solve the problem of determining the parameters of the relative motion of the NSC which is in free uncontrolled motion. The filter can be implemented under conditions of the limited computational capability available on onboard processors. The relative motion parameters include the distance vector between the centers of mass (c.m.) of the NSC and the SSC, the relative velocity vector, the quaternion of the orientation of the main axes of inertia of the satellite relative to the inertial coordinate system, the ratio of the moments of inertia of the satellite, the vector of the position of the NSC c.m. in the graphical coordinate system. The properties of the proposed algorithm are demonstrated using numerical simulation. The results obtained are expected to be used in the development, creation and testing of a navigation system for the rendezvous and docking of the SSC, developed by a group of Ukrainian space industry enterprises under the leadership of the LLC «Kurs-orbital» (https://kursorbital.com/).

Objectives. The paper considers a satellite with an optoelectronic payload designed to take pictures of the Earth’s surface. The work sets out to develop a mathematical model for determining the dependencies between the state vector of the satellite, the state vector of the point being imaged on the Earth’s surface, and the distribution fields of the velocity vectors and accelerations of the motion of the image along the focal plane of the optoelectronic payload.Methods. The method is based on double differentiation of the photogrammetry equation when applied to a survey of the Earth’s surface from space. For modeling the orbital and angular motion of the satellite, differential equations with numerical integration were used. The motion parameters of the Earth’s surface were calculated based on the Standards of Fundamental Astronomy software library.Results. Differential equations of motion of the image were obtained. Verification of the developed mathematical model was carried out. The motion of the considered satellite was simulated in orbital orientation mode using an image velocity compensation model. The distribution fields of velocity vectors and accelerations of motion of the image of the Earth’s surface were constructed. The residual motion of the field of image following compensation was investigated.Conclusions. The proposed mathematical model can be used both with an optoelectronic payload when modeling shooting modes and estimating image displacements at the design stage of a satellite, as well as at the satellite operation stage when incorporating the presented model in the onboard satellite software. The presented dependencies can also be used to construct an image transformation matrix, both when restoring an image and when obtaining a super-resolution.

Abstract At the symbolic centre of every Dickens novel is the roaring fire of a domestic hearth. Readers of Dickens frequently related clustering in familial groups around a fireplace, sharing in the fire’s uncertain pools of light and warmth while they read the text aloud. And within the texts themselves, the Dickens fireside has been seen as an idyllic space of conflict resolution: as Alexander Welsh has put it, “if the problem that besets” Dickens “can be called the city, his answer can be named the hearth.” This essay seeks to remember the materiality of the fireside alongside its more symbolic evocations. Comparing Dickens’s representation of the coal fuelling the fires of A Christmas Carol (1843) and Our Mutual Friend (1865), written over twenty years later, and taking in several short fictions published in Household Words in the intervening decade, it shows that Dickens often based plots of fictional transformation on the fantastic metamorphoses embodied in the lump of coal itself. While there was something exuberant about this change in the 1840s and 1850s, when Britain’s plentiful coal supplies were frequently imagined as tokens of a divine plan favourable to British industrial and imperial expansion, the darkening mood of Dickens’s late fiction chimed with contemporary fears about the waste and depletion of resources and the increasing competitiveness of the global markets. Most importantly, however, throughout his career the material dimension of coal offered Dickens both narrative possibility, and representational trouble. So important was it to his social vision that he often overlooked the cost of coal in his desire to keep his poorest characters warm, and in the 1860s he repeatedly ridiculed the national panic that Britain’s coal reserves might run out. Thinking about Dickens’s firesides as both symbolic and material spaces, fuelled by the coal whose history was of such fascination to the readers of Household Words, we see that the hearth was not only Dickens’s all-solving “answer” to the problems of the “city.” It was a space in which many of his most central concerns would sit in unequal, and unresolved, tension.

Abstract The present paper describes the development of a mobile platform as a support of the real estate appraisal procedure. Currently, the estate evaluation is performed by an expert that manually collects data, performs measurements, and grabs pictures of the inspected unit to finally evaluate its commercial value. The READ project aims at automatizing this process by developing a solution based on a mobile unit (drone or tablet) able to navigate the indoor environment and record data, which will be later processed on the cloud. To accomplish all these tasks, the platform is equipped with cameras, a LiDAR sensor, and a data process unit, with the goal of 1) understanding its motion and localization; 2) reconstructing a 3D map of the inspected space; 3) performing image-based analyses applying AI algorithms enabling the identification of the indoor space (e.g. bedroom or kitchen), the counting and the classification of furniture objects, and the detection of building imperfections or frauds. Tests have been performed in different scenarios providing promising results, laying the foundations for bringing these technologies into a real operational context.

The combination of gesture recognition and aerospace exploration robots can realize the efficient non-contact control of the robots. In the harsh aerospace environment, the captured gesture images are usually blurred and damaged inevitably. The motion blurred images not only cause part of the transmitted information to be lost, but also affect the effect of neural network training in the later stage. To improve the speed and accuracy of motion blurred gestures recognition, the algorithm of YOLOv4 (You Only Look Once, vision 4) is studied from the two aspects of motion blurred image processing and model optimization. The DeblurGanv2 is employed to remove the motion blur of the gestures in YOLOv4 network input pictures. In terms of model structure, the K-means++ algorithm is used to cluster the priori boxes for obtaining the more appropriate size parameters of the priori boxes. The CBAM attention mechanism and SPP (spatial pyramid pooling layer) structure are added to YOLOv4 model to improve the efficiency of network learning. The dataset for network training is designed for the human–computer interaction in the aerospace space. To reduce the redundant features of the captured images and enhance the effect of model training, the Wiener filter and bilateral filter are superimposed on the blurred images in the dataset to simply remove the motion blur. The augmentation of the model is executed by imitating different environments. A YOLOv4-gesture model is built, which collaborates with K-means++ algorithm, the CBAM and SPP mechanism. A DeblurGanv2 model is built to process the input images of the YOLOv4 target recognition. The YOLOv4-motion-blur-gesture model is composed of the YOLOv4-gesture and the DeblurGanv2. The augmented and enhanced gesture data set is used to simulate the model training. The experimental results demonstrate that the YOLOv4-motion-blur-gesture model has relatively better performance. The proposed model has the high inclusiveness and accuracy recognition effect in the real-time interaction of motion blur gestures, it improves the network training speed by 30%, the target detection accuracy by 10%, and the value of mAP by about 10%. The constructed YOLOv4-motion-blur-gesture model has a stable performance. It can not only meet the real-time human–computer interaction in aerospace space under real-time complex conditions, but also can be applied to other application environments under complex backgrounds requiring real-time detection.

Abstract Secular dynamics inside mean motion resonances (MMRs) plays an essential role in governing the dynamical structure of the trans-Neptunian region and sculpting the orbital distribution of trans-Neptunian objects (TNOs). In this study, semianalytical developments are made to explore the von Zeipel–Lidov–Kozai resonance inside MMRs. To this end, a semi-secular model is formulated from averaging theory and then a single-degree-of-freedom integrable model is achieved based on the adiabatic invariance approximation. In particular, we introduce a modified adiabatic invariant, which is continuous around the separatrices of MMRs. During long-term evolution, both the resonant Hamiltonian and the adiabatic invariant remain unchanged, thus phase portraits can be produced by plotting level curves of the adiabatic invariant with a given Hamiltonian. The phase portraits provide global pictures to predict long-term behaviors of the eccentricity, inclination, and argument of pericenter. Applications to some representative TNOs inside MMRs (2018 VO137, 2005 SD278, 2015 PD312, Pluto, 2004 HA79, 1996 TR66, and 2014 SR373) show good agreements between the numerically propagated trajectories under the full N-body model and the level curves arising in phase portraits. Interestingly, 2018 VO137 and 2005 SD278 exhibit switching behaviors during their long-term evolution and currently they are inside 2:5 MMR with Neptune.

We examine radiation and its effects on accretion disks orbiting astrophysical black holes. These disks are thermally radiating and can be geometrically and optically thin or thick. In this first paper of the series, we discuss the physics and the formulation required for this study. Subsequently, we construct and solve the relativistic radiative transfer equation, or find suitable solutions where that is not possible. We continue by presenting some of the accretion disks we considered for this work. We then describe the families of codes developed in order to study particle trajectories in strong gravity, calculate radiation forces exerted onto the disk material, and generate observation pictures of black hole systems at infinity. Furthermore, we also examine the veracity and accuracy of our work. Finally, we investigate how we can further use our results to estimate the black hole spin and the motion of disk material subjected to these radiation forces.

The rapidly changing political world can hardly be described within the framework of state concepts and strate-gies. The search for new tools capable of explaining and analyzing foreign and domestic political processes reinforces the notion of the political picture of the world. The aim of the study is to fundamentally comprehend this concept. It is analyzed through the theoretical prism of the concepts of leading political philosophers of the XX century and modernity: the phenomenological method of E. Husserl and A. Schütz, the subjective space of politics by M. Heidegger, the political distinction between “friends” and “enemies” by K. Schmitt, the correlation of the categories “world picture” and “life world” by J. Habermas. The author ascertains that the task of forming an independent concept of the political picture of the world in political science has not been raised so far, and the term “political picture of the world” has not been definitively defined. Conclusion dwells upon its plural and dynamic character. Plurality is manifested in the subject-object and communicative reflection of pictures of the world. The dynamic nature can be expressed both in the collision of different political worldviews and in the conflict of their internal elements, which can eventually lead to the transformation of pictures of the world. Based on the analysis of the discourse of a number of scientific studies, the author’s formulation of the concept of “political picture of the world” is proffered.

Texto completoResumen
The article is devoted to the semiotic interpretation of the theoretical heritage of S.M. Eisenstein, the film maker who anticipated the structuralist approach which has been so popular from the 1960s. Back in the 1960s, Eisensteins heritage attracted the attention of Academician Vyacheslav Ivanov because he found there he found a trend for understanding cinema as a language or, to be more precise, as a semiotic system. Vyacheslav Ivanov could not but notice it, as the formation of semiotics methodology in Russia is associated with his name. No wonder that he would reflect on the background of art semiotics which in the sphere of motion pictures is associating with the name of S.M. Eisenstein. While trying to appreciate the significance of Vyacheslav Ivanovs research of Eisensteins aesthetics, the author is contemplates on the application of semiotics methodology to the cinema as a semiotic system. In this regard the article is reproducing the aura of devotion to semiotics of domestic film scholars. When explaining the meaning of the title of Ivanovs book on S. Eisenstein, the author argues that the concept of semiotics was initially developed on the stage of the formation of aesthetics as a philosophical science.

ABSTRACT We develop simple, physically motivated models for drag-induced dust–gas streaming instabilities, which are thought to be crucial for clumping grains to form planetesimals in protoplanetary discs. The models explain, based on the physics of gaseous epicyclic motion and dust–gas drag forces, the most important features of the streaming instability and its simple generalization, the disc settling instability. Some of the key properties explained by our models include the sudden change in the growth rate of the streaming instability when the dust-to-gas mass ratio surpasses one, the slow growth rate of the streaming instability compared to the settling instability for smaller grains, and the main physical processes underlying the growth of the most unstable modes in different regimes. As well as providing helpful simplified pictures for understanding the operation of an interesting and fundamental astrophysical fluid instability, our models may prove useful for analysing simulations and developing non-linear theories of planetesimal growth in discs.

Texto completoResumen
Vaudeville theatre was an important visual form of popular culture and entertainment that featured such specialty acts as comedy and song and dance, as well as lectures, lantern slide shows and motion pictures with subject matter from faraway lands, and themes of American patriotism. American vaudeville began in nineteenth-century saloons as floorshows and burlesque, but it was eventually upgraded to family entertainment, which appealed to middle- and upper-class audiences, before individual theatres were subsumed by franchised theatre chains. Vaudeville theatre directors, who were known as impresarios, programmed an innovative spectrum of acts that ranged from classical music and art to folk songs, and to acrobats, which appealed to a wide range of social classes. Following the theories of Henri Lefebvre, the social space of the theatre became a conceptually dynamic space, where class distinctions blurred and audience members could then dream of life in a higher social station, or what American Mid Victorians knew as ‘self-improvement’. A conundrum emerges, however, when we see that most of the programmes were plentiful with racial, ethnic and gender stereotypes, which were entertaining to White audience members. The vertical social climb of the gilded age in the 1900s was complicated with the social relations of uneasy, decadent consumerism. Individuals driven by desire thought their ‘un-comfort’ might be remedied by entertainment, as they looked for an upswing to something better.

Abstract The surveillance system has been utilized over the years on public property in order to provide security and prevent unauthorized entrance. Lately, more private homeowners are choosing to implement security systems. There are many problems with the video surveillance system. These disadvantages are the indistinctiveness of the pictures/video and the need for a lot of storage space to save surveillance information. This paper describes the design and implementation of a low-cost Web Monitoring System based on Raspberry Pi. Also, a web application is designed for the purposes of controlling the camera and for live streaming. The live stream from a web camera can be viewed from any web browser, even mobile, in real-time. Controlling the camera is possible with the web application using four commands (up/down, left/right). Also, the camera moves depending on the detection of an object located in the visible area of the PIR Motion sensor, thereby issuing a warning message about object detection.

Super-resolution magnetic resonance (MR) scans give anatomical data for quantitative analysis and treatment. The use of convolutional neural networks (CNNs) in image processing and deep learning research have led to super-resolution reconstruction methods based on deep learning. The study offers a G-guided generative multilevel network for training 3D neural networks with poorly sampled MR input data. The author suggest using super-resolution reconstruction (SRR) and modified sparse sampling to address these issues. Image-based Wasserstein GANs retain k-space data sparsity. Wasserstein Generative Adversarial Networks (WGANs) store and represent picture space knowledge. The method obtains null-valued k-space data and repairs fill gaps in the dataset to preserve data integrity. The proposed reconstruction method processes raw data samples and is able to perform subspace synchronization, deblurring, denoising, motion estimation, and super-resolution image production. The suggested algorithm uses different preprocessing methods to deblur and denoise datasets. Preliminary trials contextualize and speed up assessments. Results indicate that reconstructed pictures have better high-frequency features than sophisticated multi-frame techniques. This is supported by rising PSNR, MAE, and IEM measurements. A k-space correction block improves GAN network refinement learning in the suggested method. This block improves the network’s ability to avoid unnecessary data, speeding reconstruction. A k-space correction module can limit the generator’s output to critical lines, allowing the reconstruction of only missing lines. This improves convergence and speeds rebuilding. This study shows that this strategy reduces aliasing artifacts better than contemporaneous and noniterative methods.

The purpose of this study was to construct a static and dynamic anthropometric database for domestic population in Taiwan. This anthropometric database is divided into static body dimensions and dynamic ranges of motion. A direct measurement method was applied to measure static body dimensions and an optical method was employed for dynamic range measurement. The static body dimensions include three parts furthermore. The first part is to measure the space coordinates of landmarks of body surface and calculate the meaningful related distances between any two landmarks. The equipment to take the space coordinates of surface landmarks is a 3-D coordination measuring probe. Ninety four surface landmarks are measured and 141 items are calculated in this part. The second part is to measure the length and thickness dimensions of human body with a digital caliper and 27 items are measured. The third part is to measure the circumference and length of the curve with a digital tape measure. Ninety eight items are measured here. The dynamic ranges of motion contain 42 angles of motion of major body joints. The equipment used to measure the ranges of motion is a 3-D motion analyzer. A total of 10019 subjects were measured, i.e. 1200 workers, 610 Army soldiers, 502 university students, 1200 senior high school students, 3207 junior high school students and 3300 elementary school students. The age ranges from 12 to 64 years old. The data are presented in a computerized query system. It is expected that the data can be used by designers, engineers or any other people for developing ergonomic designs of equipment, product and workplace environment, and standard legislation. Ultimately, a healthy and comfortable living environment and a high quality of working life can be achieved in the near future.

We propose a new systematic fibre bundle formulation of nonrelativistic quantum mechanics. The new form of the theory is equivalent to the usual one and is in harmony with the modern trends in theoretical physics and potentially admits new generalizations in different directions. In it the Hilbert space of a quantum system (from conventional quantum mechanics) is replaced with an appropriate Hilbert bundle of states and a pure state of the system is described by a lifting of paths or section along paths in this bundle. The evolution of a pure state is determined through the bundle (analog of the) Schrödinger equation. Now the dynamical variables and density operators are described via liftings of paths or morphisms along paths in suitable bundles. The mentioned quantities are connected by a number of relations derived in this work. The present fourth part of this series is devoted mainly to the fibre bundle description of mixed quantum states. We show that to the conventional density operator there corresponds a unique density lifting of paths for which the corresponding equations of motion are derived. It is also investigated the bundle description of mixed quantum states in the different pictures of motion. We calculate the curvature of the evolution transport and prove that it is curvature free iff the values of the Hamiltonian operator at different moments commute.

We studied the development of spontaneous tactile drawing in three 12-year-old children with congenital total blindness and with no previous drawing tuition. In a period of 9 months, from an initial phase in which they were taught to draw tangible straight and curve raised lines, the three blind children went on making spontaneous raised outlines representing edges, surfaces of objects, vantage point, and motion. The corpus of drawings produced by these children shows that several aspects of outline pictures can be implemented through touch. The perceptual principles represented in these drawings are comparable to those commonly found in sighted children. On the one hand, this convergence indicates similarities in the way vision and touch mediate the acquisition and the conceptualisation of spatial information from objects and the environment. On the other hand, it reflects the influence of cross-modal plasticity typically associated with early or congenital blindness. This study suggests that drawing development in general does not depend on learning pictorial conventions. Rather it seems driven by natural generativity based on children’s knowledge of space and perceptual principles.

The additively manufactured particle damper (AMPD) is a novel particle damper fabricated by leaving unfused powder inside the pre-designed structural cavities during the laser powder bed fusion (LPBF) process. It can be applied at high temperatures and a wide range of frequencies without any additional installation space. However, the damping mechanism and performance of AMPD are still unclear due to insufficient experimental and simulation analyses. In this work, the damping capacity of AMPDs with three different unit cell sizes at high frequencies and low vibration amplitudes were investigated experimentally and numerically. The AMPDs were manufactured using LPBD with 316 L stainless steel. The complex power method was used to measure the energy dissipation of the AMPD directly. A discrete element method (DEM) simulation model was developed to visualize the particle motion mode during each vibration process. The computed tomography (CT) pictures were utilized to measure the powder distribution in each AMPD's cavity. Finally, the influence of excitation frequency, excitation amplitude, and cavity size on the damping performance of the AMPD were explained by comparing the experimental and simulation results.

The article addresses the pictorial representation of the so-called “field camp” in Soviet realist painting. A field camp is a temporary site equipped for providing meals and recreation to agrarian workers and situated as close to the place of their labor activity as it possible, i.e. directly in a field. Pictures representing the field camp portray Soviet people, workers, in the process of their creative labor for the sake of socialism, which allows us to treat this type of painting as an example of Socialist realism. Amongst the multiple subjects concerning the labor activity of Soviet people, the pictorial representation of the field camp as a space of work and recreation is of interest, because it reflects the specific to Soviet culture views on the role and value of agrarian labor. Our study has pursued two main purposes: - to demonstrate the symbolical value of the field camp pictorial representation and its influence on the development of Socialist realist painting in general; - to reveal a semiotic system (a system of visual images – the signifiers) which enables pictures representing the field camp to function efficiently in Soviet painting. In the course of the study we have also accomplished several additional tasks: - to outline the history of the subject under consideration in Soviet painting; - to interpret shifts in the representation of the subject in order to reveal their connection with the transformation of artistic strategies and ideological discourse. The study addresses some new issues. Soviet painting representing agrarian labor has never been considered in cultural studies. From such a perspective, Socialist realist painting is significant as a historical source for studying Soviet culture and ideology. The analysis of a range of images representing the field camp demonstrates that having emerged in the 1930-s the pictorial representation of agrarian labor became one of the most popular subjects in the 1960s – 1970s. Such pictures make evident the essential difference between the socialist agrarian labor and the traditional farming. The field camp represents the meal of a working team, thereby manifesting the new form of social and labor relationships. The representation of the field camp acquired the following significant features: - the agrarian worker is portrayed in a new manner; - agrarian labor reflects the harmony of people and nature; - agrarian labor is depicted as the space of social harmony. We have also identified a variety of semiotic structures, which serve to express these specific features. These are the groups of signifiers representing gender relationships, opposition of “natural” and “technical”, dialectics of “individual” and “collective”, continuity of labor and domestic activities.

The starting hypothesis in this work is that human freedom can be recognized in the extent of the ability for free motion. From the historical perspective, human conquers freedom through motion. The plant is fixed to the soil and moves only as carried by wind, swinging or rolling. Animals move in own domicile environment, while man conquered entire earth and launched into space but still contains "plantlike features" as Oswald Sprengler noticed. Human moves not only in physical but in spiritual way as well. By conquering the space/time dimension, human lives faster and faster. The persistent acceleration of live reached everyday existence, so that the loss of freedom is constantly felt, causing confusion, frustration, increase of violence and distortion of system of values. Prediction of future is a great challenge for every science, especially sociology. It seems that future arrives in everyday life faster than sociology can predict. Socialism left the world scene, while capitalism is falling apart, runs it last circle while sociologists are sophisticating over the wise sayings of Plato, Aristotle, Fromm, Sartre and postmodernism. They do not deal with the futurology striving to preserve scientific "dignity" and honor, hiding within traditional methodology.

The implementation of aspects of literary cinematography in Dmitry Danilov’s novel “Sasha, hello!”, which was analyzed using contextual, structuralist methods, the method of holistic analysis of a literary text, is considered. For the analysis, the concepts of “literary cinematography”, “audiovisuality”, “edit”, “plot”, “chronotope”, “eye” and “look”, “image of the author”, “reader-viewer” are used, the specifics of cinema as a fact of culture. It is substantiated that literary and cinematic codes are intertwined within the framework of this work. The specificity of the implementation of the principle of audiovisuality in the text is considered. It is revealed that the text is built according to the assembly principle. To construct the plot, the writer uses, among other things, emphatically cinematic plot. At the same time, the emphasized visibility of history, the orientation towards the creation of visible spaces allows the writer to create a specific absurdist narrative. The use of the vocabulary of the “Kino” group and the inclusion of the image of the author in the form of a conditional director-screenwriter transform the very status of a literary text. This makes it possible to present a literary work as an analogue of a motion picture, while actualizing the interactive moment, including the reader-viewer in the unfolding of the text. The materials of the study and its conclusions can be used not only to analyze other works by D. Danilov, but also in the analysis of modern domestic and world literature in the context of literary cinematography and the relationship between literature and cinema.

Abstract We consider a situation in which a brightest cluster galaxy (BCG) moves in ambient hot gas in the central region of a cool core cluster of galaxies, following the study by Inoue (2014, PASJ, 66, 60). In the rest frame of the BCG, the hot gas is supposed to flow toward the BCG in parallel from a sufficiently large distance. Then, it is expected that only the gas flowing with an impact parameter less than a critical value is trapped by the gravitation field of the BCG because of the efficient radiative cooling, getting a cooling flow, and that the remaining outer gas can get over the potential well. In such a circumstance, we can draw the following picture: A boundary layer between the out-flowing gas and the trapped gas arises around the stagnation point at the back side of the BCG. Since the boundary temperature is so low as to be X-ray dim, the boundary could be observed as the cold front in X-rays. The trapped gas stagnates on the inner side of the boundary and starts in-falling toward the BCG. Since the wandering motion of the BCG is likely to have a rotational component, the Coriolis force induces a rotational motion in the in-falling flow from the stagnation place to the BCG, forming a spiral structure around the BCG. The spiraling flow turns the BCG on the up stream side of the main flow from the far outside, and another boundary layer arises that has contact discontinuity with the main hot gas flow. These pictures reproduce the observed features such as cool cores, cold fronts, and spiral structures well. It can also be resolved how the cooling flow is suppressed from what the cooling flow hypothesis predicts, without any heating mechanism.

Abstract: Suspicious Activity is predicting the part or joint locations of someone from a picture or a video. Human suspicious Activity is one amongst the key issues in laptop vision that has been studied for over fifteen years. it's necessary due to the sheer variety of applications which mightlike Activity detection. for instance, human cause estimation is employed in applications as well as video police investigation, animal following and behavior understanding, language detection, advanced human-computer interaction, and marker less motion capturing. Low price depth sensors have limitations like restricted to indoor use, and their low resolution and yelling depth info build it troublesome to estimate human poses from depth pictures. Hence, we have a tendency to attempt to use neural networks to over- return these issues. Suspicious act recognition from police investigation video is an energetic analysis space of image process and laptop vision. Through the visual police investigation, human activities may be monitored in sensitive and public areas like busstations, railway stations, airports, banks, searching malls, faculty and faculties, parking tons, roads, etc. to stop act of terrorism, theft, accidents and ill-gotten parking, vandalism, fighting, chain snatching, crime and different suspicious activities.

Motion and aggressive behaviors in pigs provide important information for the study of social hierarchies in pigs and can be used as a selection indicator for pig health and aggression parameters. However, relying only on visual observation or surveillance video to record the number of aggressive acts is time-consuming, labor-intensive, and lasts for only a short period of time. Manual observation is too short compared to the growth cycle of pigs, and complete recording is impractical in large farms. In addition, due to the complex process of assessing the intensity of pig aggression, manual recording is highly influenced by human subjective vision. In order to efficiently record pig motion and aggressive behaviors as parameters for breeding selection and behavioral studies, the videos and pictures were collected from typical commercial farms, with each unit including 8~20 pigs in 7~25 m2 space; they were bred in stable social groups and a video was set up to record the whole day’s activities. We proposed a deep learning-based recognition method for detecting and recognizing the movement and aggressive behaviors of pigs by recording and annotating head-to-head tapping, head-to-body tapping, neck biting, body biting, and ear biting during fighting. The method uses an improved EMA-YOLOv8 model and a target tracking algorithm to assign a unique digital identity code to each pig, while efficiently recognizing and recording pig motion and aggressive behaviors and tracking them, thus providing statistics on the speed and duration of pig motion. On the test dataset, the average precision of the model was 96.4%, indicating that the model has high accuracy in detecting a pig’s identity and its fighting behaviors. The model detection results were highly correlated with the manual recording results (R2 of 0.9804 and 0.9856, respectively), indicating that the method has high accuracy and effectiveness. In summary, the method realized the detection and identification of motion duration and aggressive behavior of pigs under natural conditions, and provided reliable data and technical support for the study of the social hierarchy of pigs and the selection of pig health and aggression phenotypes.

The Old White Man is a local deity revered by Buddhists in Russia. His image, based on textual traditions and Buddhist iconography, prompted the name — the Old White Man, now widely accepted. In the written sources he is also known as the “Conqueror and subduer of the [master spirits] of earth and water”. The early images appeared in Mongolia under the influence of the Chinese traditional pictures of Tú Dì, ancient deities associated with localities, while later they were influenced by traditional images of Shòuxing, the deity of longevity. At an early stage of the iconographic tradition, the Old White Man is depicted as a priest or a high official; his functions are rendered via the characters of his companions, the host spirits of mountains (sabdaks) that have the features of man and animal or animals, such as a pair of deer, chained leopard (wolf), as well as ritual objects, including a carved staff or a dragon head staff. At a later stage, there may be symbols associated with the giver of longevity and fertility (bald phallic head, cave, and peach). The text of the “Sutra of the Old White Man” includes the description of his appearance (a white-bearded, bare-headed old man in a white robe), attributes (a dragon head staff) and an allegorical landscape of a mountain and fruit trees. Neither early nor recent Mongolian and Buryat pictures fully correspond to the description. Much closer to it is the Kalmyk iconographic tradition. The Old White Man’s image of the Kalmyk nomads goes back to the ancient mythological idea of the deity as the keeper of domestic animals. Due to transformations in the religious sphere, the keeper of domestic animals becomes the Old White Man, the lord of all living beings and all earthly space. Traditionally, he is presented as a standing old man, bare-headed and his long gray hair gathered in the form of a triratna. He is dressed in a belted robe, with another swinging robe thrown on it. In his right hand, he holds a staff with a dragon’s head and a rosary in his left. There are no companions or animals. The symbolic landscape serves to enhance the grandiose figure of the old man. The details of the attire and the landscape refer to the former Chinese influence.

The paper considers the style manner of V. Drozd’s prose from his early writing period with a focus on cinematographic aesthetics of color and possibilities of the screen design of plein air as the most free spatial environment for visual development of the image. The writer’s literary means have their analogues in the well-known contemporary films (“October”, “Poem about Sea”, “Red Desert”).
The dynamic plein air compositions have certain screen potential. The images of open-space are related to freedom in dynamic and successive change of a scene, and alternation of verbal pictures. They are rather close to the specifc cinematographic representation of action, as their color markers may be associated with an imaginary film. The first V. Drozd’s attempts of designing the color and light of plein air are marked with an accent on the hues of the represented objects, the dynamism of objects in the imaginary shots, and expressive motion, increased with spectral indicators. A growth of the writer’s mastery is related to development of successive color ‘melody’, based on nuances of the visual impressions, and harmonized with internal action progress. Plastic imaginal markers with limited color range also remind the technique of cinematographic rush, adding emotional and psychological mood connotations to the narration and stimulating positive (nostalgic, elegiac) associations. Although they may seem random, the light and color signals acquire cinematographic expressiveness due to integration into the plot and its internal action, and to the dynamics of the character’s point of view. Abandoning a picturesque fixed nature, the author acquires possibility to decode wider associative meanings with color and light markers, search for deeper semantics of visual image complexes, and construct deterministic relations of a character and environment. Even minimal visual signals contribute to the color structure of a verbal shot. Such terseness and obscurity of objects in the prospect of a narrative camera, and a rapid change of plein air sections are similar to the features of cinematographic aesthetics and poetics.

The article presents the results of the performed analytical and experimental studies of the hydrodynamics of the translationalrotational motion of a viscous incompressible gas flow in the working space of a vortex heat generator of variable geometry, analytically determined the dependences of the effect of device performance, confuser opening angles, confuser channel width on the hydrodynamic parameters of the device and, as a consequence, its energy efficiency. The degree of energy efficiency of the swirler screw for the operation of a vortex heat generator at various loads on the working path has been experimentally estimated, according to the Euler number EUc. It has been proven that the energy efficiency of its operation is on average 35% higher when the swirler screw is installed. The influence of the geometry of the nozzle on the axial symmetry and smoothness of the flow of incompressible gas in the vortex chamber is investigated. It was found that the specified indicator is most satisfactory for a nozzle with a rectangular cross-section. The distribution of the temperature field of a moving incompressible gas along the height of the vortex chamber is investigated depending on the taper angle. The distribution of angular velocities along the axis of the flow swirler is investigated at various values of productivity. It was found that the angular velocity decreases according to the law of potential fluid flow. A mathematical model has been developed to optimize the operating modes and parameters of the vortex heat generator. A software block was built based on the mathematical package MathCAD version 11 for the implementation of the developed mathematical model. An optimal design of a vortex heat generator with a variable geometry of the working space has been developed, which has been tested in laboratory conditions. Laboratory studies have proven its high energy efficiency at the level of modern standards and the feasibility of using the device for heating buildings and structures in industry and the domestic sector. Keywords: incompressible gas, hydrodynamics of an incompressible gas flow, vortex motion, mathematical model, equation of motion, continuity equation, vortex heat generator, thermal energy, cavitation, turbulence, vortex zone, MathCAD package.

We explored how people learn new ways to move objects through space using neuromuscular control signals having more degrees of freedom than needed to unambiguously specify object location. Subjects wore an instrumented glove that recorded finger motions. A linear transformation matrix projected joint angle signals (a high-dimensional control vector) onto a two-dimensional cursor position on a video monitor. We assessed how visual information influences learning and generalization of novel finger coordination patterns as subjects practiced using hand gestures to manipulate cursor location. Three groups of test subjects practiced moving a visible cursor between different sets of screen targets. The hand-to-screen transformation was designed such that the different sets of targets (which we called implicit spatial cues) varied in how informative they were about the gestures to be learned. A separate control group practiced gesturing with explicit cues (pictures of desired gestures) without ongoing cursor feedback. Another control group received implicit spatial cueing and feedback only of final cursor position. We found that test subjects and subjects provided with explicit cues could learn to produce desired gestures, although training efficacy decreased as the amount of task-relevant feedback decreased. Although both control groups learned to associate screen targets with specific gestures, only subjects provided with online feedback of cursor motion learned to generalize in a manner consistent with the internal representation of an inverse hand-to-screen mapping. These findings suggest that spatial learning and generalization require dynamic feedback of object motion in response to control signal changes; static information regarding geometric relationships between controller and endpoint configurations does not suffice.

Abstract Economic growth of any nation is depending on the Gross Domestic Product. To improve a country economy, the industries needs to produce gross domestic products at large rate for export. Every industry has value added and non-value added (waste) activities. Non – value added activities always pulls down the efficiency, effectiveness and profit of the industry which will lets to devastating future. In order to overcome the waste many works and research has to be carried out with the focus on lean implementation. Lean implementation should be carried out progressively to obtain fruitful result. This project has been carried out on a casting industry in which non value added activities such as unnecessary transportation, motion, and waiting and high space conception are identified using current state mapping and current state layout. It is highly complicated to implement all the lean tools in a manufacturing system. So to prioritize only few lean tools which are essential to eliminate those wastes and an integrated model (combine fuzzy and FMEA environment) was used. Fuzzy is to avoid ambiguity in observation and FMEA is to prioritize the cause. After eliminating the wastes, future state value stream mapping is drawn and its performance is compared with the existing layout.
