Abstract:
We establish the correspondence between two apparently unrelated but in fact complementary approaches of a relativistic deformed kinematics: the geometric properties of momentum space and the loss of absolute locality in canonical space-time, which can be restored with the introduction of a generalized space-time. This correspondence is made explicit for the case of κ-Poincaré kinematics and compared with its properties in the Hopf algebra framework.

Abstract:
A correspondence between the SO5 theory of high-TC superconductivity and antiferromagnetism, put forward by Zhang and collaborators, and a theory of gravity arising from symmetry breaking of a SO5 gauge field is presented. A physical correspondence between the order parameters of the unified SC/AF theory and the generators of the gravitational gauge connection is conjectured. A preliminary identification of regions of geometry, in solutions of Einstein’s equations describing charged-rotating black holes embedded in de Sitter space-time, with SC and AF phases is carried out.

The article shows how mathematics can describe the process of the decay of space-time to infinite number of different space-times, which from the point of view of some observer are eternal. The relation of this decay to the time entanglement of quantum fields on an infinitely distant boundary of space-time within the 𝐴𝑑𝑆/𝐶𝐹 𝑇-correspondence is considered.

Abstract:
We present the quantization process for Schwarzschild space-time in the context of Teleparallel gravity. In order to achieve such a goal we use the Weyl formalism that establishes a well-defined correspondence between classical quantities which are realized by functions and quantum ones which are realized by operators. In the process of quantization we introduce a fundamental constant that is used to construct what we call the quantum of matter by the imposition of periodic conditions over the eigenfunction.

Abstract:
In this paper, by analyzing the thermodynamic properties of charged AdS black hole and asymptotically flat space-time charged black hole in the vicinity of the critical point, we establish the correspondence between the thermodynamic parameters of asymptotically flat space-time and nonasymptotically flat space-time, based on the equality of black hole horizon area in the two different types of space-time. The relationship between the cavity radius (which is introduced in the study of asymptotically flat space-time charged black holes) and the cosmological constant (which is introduced in the study of nonasymptotically flat space-time) is determined. The establishment of the correspondence between the thermodynamics parameters in two different types of space-time is beneficial to the mutual promotion of different time-space black hole research, which is helpful to understand the thermodynamics and quantum properties of black hole in space-time.

Abstract:
The subject of this research is the points of intersection of space-time relations of the “foreign world” in such form of authorial self-expression as correspondence of the English romanticists. The goal is to examine the key elements of the chronotope of “foreign world”, and determine the peculiarities of their functionality in the romantic epistolary prose. The object of this research is the 50 letters of W. Wordsworth, 224 letters of G. G. Byron, 67 letters of P. B. Shelley, 51 letters of J. Keats, and 200 letters of R. Southey. The article employs a set of general scientific and special literary criticism methods, such as descriptive, biographical, historical-genetic, historical-functional, structural-semantic, and comparative-typological. It is established that the “foreign world” in the correspondence of English romanticists is represented by the following points of intersection of space-time planes: chronotope of the road / road meetup / traffic accident; contact / meetup / date; cities / countries / villages, with the dominant motifs of the road and contact. Leaning on the analysis of space-time plane of the “foreign world” in the correspondence of English romanticists, the conclusion is made that the chronotope of “foreign world” is a certain access code to the world pattern of English romanticists, the key category that resembles the worldview of a particular epoch, namely romanticism. The scientific novelty lies in the fact that this work is first to analyze space-time relations of “foreign world” in the correspondence of English romanticists. The future research should focus on the types and peculiarities of functionality of the chronotope of “native world” in the correspondence of English romanticists, as well as the interaction of space and time in the correspondence of English realist writers, determining and comparing the integral and variable traits characteristic to epistolary prose as a whole.

Abstract:
Abstract This study examines people-centred Thai NGOs trying to help peasants empower themselves in order to compete better in conflicts over land, water, forest, and capital, during the 1970s to 1990s. The study investigates how the NGOs contested asymmetric power relations among government officials, private entrepreneurs and ordinary people while helping raise the people’s confidence in their own power to negotiate their demands with other actors.¶ The thesis argues that the NGOs are able to play an interventionist role when a number of key factors coexist. First, the NGOs are able to understand local situations, which contain asymmetric power relations between different actors, in relation to current changes in the wider context of the Thai political economy and seize the time to take action. Secondly, the NGOs are able to articulate a social meaning beyond the dominating rhetoric of the ‘state’ and the ‘capitalists’ which encourages the people’s participation in collective activities. Thirdly, while dealing with one problem in social relations and negotiation with local environment, the NGOs are able to recognise new problems as they arise and rapidly identify a new political space for the actors to renegotiate their conflicting interests and demands. Fourthly, the NGOs are able to recreate new meanings, new actors and reform their organisations and networks to deal with new situations. Finally, the NGOs are able to effectively use three pillars of their movement, namely individuals, organisations and networks to deal with everyday politics and collective protest.¶ The case studies in three villages in Northern Thailand reveal that the NGOs were able to play an interventionist role in specific situations through their alternative development strategies somewhat influenced by structural Marxism. The thesis recommends that the NGO interventionist role be continued so as to overcome tensions within the NGO community, for instance, between the NGOs working at the grass-roots level and the NGOs working at regional and national levels (including NGO funding agencies); local everyday conflicts; and the bipolar views of a society among the NGOs expressed in dichotomous thinking between ‘rural’ and ‘urban’, ‘community’ and ‘state’, conflict and order, actor and system.¶ The fragmentation of NGO social and environmental movements showed that there is no single formula or easy solution to the problems. If the NGOs want to continue their interventionist role to help empower ordinary people and help them gain access to productive resources, they must move beyond their bipolar views of a society to discover the middle ground to search for new meanings, new actors, new issues and to create again and again counter-hegemony movements. This could be done by having abstract development theories assessed and enriched by concrete development practices and vice versa. Both theorists and practitioners need to use their own imagination to invent and reinvent what and how best to continue.

This study is the quantitative analysis on the correspondence and tendency between activity and space types for the young-old and old-old in dwelling, based on time allocations. The results are follows; 1. The more they are aging, the more they put a value on inside and outside activity types; This is different from common sense. Therefore,〝The activity theory〞of sociology may be appropriate for the aged in dwelling. 2. The more they are aging, the more they place importance on inside and outside space types; This is different from common sense too. The aged do not place importance on the space classification; Therefore,〝The universal space 〞of architecture is appropriate for the aged in dwelling.

Abstract:
Samuel Clarke is best known for the ‘Newtonian’ views on space and time he espouses in the Leibniz-Clarke correspondence. However, his writings on this topic extend far beyond that, and can help us to understand the particulars of Clarke’s metaphysics—including whether he is actually of a mind with Newton. The major part of this chapter considers Clarke’s metaphysical and epistemological views on time and space, arguing that the views Clarke puts forward in various texts can be rendered consistent. It reads Clarke as holding a position close to that of Henry More, and not the same as that of Newton. The minor part of this chapter considers Clarke’s account of divine presence in time and space, and argues that Clarke is a holenmerist.

Abstract:
Chapter 4 explores the introduction of Ronald Grimes’s ritual laboratory as a pedagogical tool in the teaching of a ritual song module within the context of a Master’s in Ritual Chant and Song at the Irish World Academy of Music and Dance. An examination of feedback and correspondence on the lab from students over the last decade and a half supports a view of the lab as a space of welcome, hospitality, and belonging. A central aspect of singing, explored in the lab, is its relationship with temporality. It suggests that it is the ability of music to collapse the clear boundaries between time and space that makes singing (particularly in ritual contexts) so successful in facilitating a sense of belonging.

Abstract:
From 1954 to 1959, Bester seemed less intent on dismissing pulp clichés than on transforming pulp aesthetics in earnest. “Fondly Fahrenheit” would not poke fun at the mad robot story but revamp it through the use of mixed-viewpoint narration, undercutting Asimov’s Three Laws of Robotics in the process. The Stars My Destination would see Bester embrace space opera but handle the form with baroque flourishes of artistry—including stream-of-consciousness narration and synesthesia—that made it sleeker and headier than ever before. This chapter argues that Bester’s distinctive approach is best described as pulp modernism. It also draws on Bester’s unpublished correspondence to reveal for the first time the fierce battle between Fantasy and Science Fiction and Galaxy over the rights to The Stars My Destination.

Abstract:
AbstractMany type systems include infinite types. In session type systems, infinite types are important because they specify communication protocols that are unbounded in time. Usually infinite session types are introduced as simple finite-state expressions "Equation missing" or by non-parametric equational definitions "Equation missing". Alternatively, some systems of label- or value-dependent session types go beyond simple recursive types. However, leaving dependent types aside, there is a much richer world of infinite session types, ranging through various forms of parametric equational definitions, to arbitrary infinite types in a coinductively defined space. We study infinite session types across a spectrum of shades of grey on the way to the bright light of general infinite types. We identify four points on the spectrum, characterised by different styles of equational definitions, and show that they form a strict hierarchy by establishing bidirectional correspondences with classes of automata: finite-state, 1-counter, pushdown and 2-counter. This allows us to establish decidability and undecidability results for type formation, type equivalence and duality in each class of types. We also consider previous work on context-free session types (and extend it to higher-order) and nested session types, and locate them on our spectrum of infinite types.

The correspondence between Leibniz and Samuel Clarke—mediated by Leibniz’s erstwhile friend and disciple at the electoral court in Hanover, Caroline of Brandenburg-Ansbach, princess of Wales—is arguably the most famous and influential of philosophical correspondences. In this chapter, I begin by tracing the background of the correspondence and the role that Caroline played in its inception and development. I then turn to a discussion of the main themes of the correspondence, paying particular attention to the importance of Caroline’s presence in shaping the themes of the debate: the principle of sufficient reason, the identity of indiscernibles, God’s choice in creating this world, space and time, God’s presence and activity in the world, miracles, and gravity.

Abstract Journalism is by nature an interdisciplinary and social practice. This chapter explores analytical frameworks that can help unpack the effects of the social world we occupy on the words we write. Social geographer David Harvey’s concept of a matrix of spatialities is combined with my autoethnographic data in Goma, Democratic Republic of Congo, to present novel arguments about the politics of reporting space. Field notes are complimented by literature from international and development studies regarding the existence and impact of Aidlands (Mosse 2011a) and Peacelands (Autesserre 2014). Bourdieu’s theory of doxa is then incorporated to consider how foreign correspondence takes place within the structures of a dominant globalizing class and how this impacts our frameworks of understanding. In knowing these structures better, journalists can consider how they impact reportage and what strategies can be put in place to decolonize reportage within these overarching neocolonial structures.

Abstract:
Leibniz’s correspondence with Burcher de Volder contains some of his most important philosophical writings. Taking place between 1698 and 1706, the correspondence engages a range of issues including the nature of substance, causation, space and time, the proper measure of force in physics, and the relation between physics and metaphysics. It is most famous for containing extensive remarks on Leibniz’s theory of monads, though the extent to which he was committed to this theory throughout the correspondence is a matter of great scholarly controversy. I suggest that one of the keys for interpreting this correspondence is to recognize its pedagogical character. Leibniz did not straightforwardly present his metaphysics to De Volder at the beginning of the correspondence; rather, he gradually revealed his views in an effort to rid De Volder of his philosophical prejudices and enable him to recognize the true metaphysical system.

Abstract:
ABSTRACT This paper summarizes the hydrological variability in eastern California (central Sierra Nevada) for the past 3000 yr based on three distinct paleoclimate proxies, δ18O, total inorganic carbon (TIC), and magnetic susceptibility (chi). These proxies, which are recorded in lake sediments of Pyramid Lake and Walker Lake, Nevada, and Mono Lake and Owens Lake, California, indicate lake-level changes that are mostly due to variations in Sierra Nevada snowpack and rainfall. We evaluated lake-level changes in the four Great Basin lake systems with regard to sediment-core locations and lake-basin morphologies, to the extent that these two factors influence the paleoclimate proxy records. We documented the strengths and weaknesses of each proxy and argue that a systematic study of all three proxies together significantly enhances our ability to characterize the regional pattern, chronology, and resolution of hydrological variability. We used paleomagnetic secular variation (PSV) to develop paleomagnetic chronostratigraphies for all four lakes. We previously published PSV records for three of the lakes (Mono, Owens, Pyramid) and developed a new PSV record herein for Walker Lake. We show that our PSV chronostratigraphies are almost identical to previously established radiocarbon-based chronologies, but that there are differences of 20–200 yr in individual age records. In addition, we used eight of the PSV inclination features to provide isochrons that permit exacting correlations between lake records. We also evaluated the temporal resolution of our proxies. Most can document decadal-scale variability over the past 1000 yr, multidecadal-scale variability for the past 2000 yr, and centennial-scale variability between 2000 and 3000 yr ago. Comparisons among our proxies show a strong coherence in the pattern of lake-level variability for all four lakes. Pyramid Lake and Walker Lake have the longest and highest-resolution records. The δ18O and TIC records yield the same pattern of lake-level variability; however, TIC may allow a somewhat higher-frequency resolution. It is not clear, however, which proxy best estimates the absolute amplitude of lake-level variability. Chi is the only available proxy that records lake-level variability in all four lakes prior to 2000 yr ago, and it shows consistent evidence of a large multicentennial period of drought. TIC, chi, and δ18O are integrative proxies in that they display the cumulative record of hydrologic variability in each lake basin. Tree-ring estimations of hydrological variability, by contrast, are incremental proxies that estimate annual variability. We compared our integrated proxies with tree-ring incremental proxies and found a strong correspondence among the two groups of proxies if the tree-ring proxies are smoothed to decadal or multidecadal averages. Together, these results indicate a common pattern of wet/dry variability in California (Sierra Nevada snowpack/rainfall) extending from a few years (notable only in the tree-ring data) to perhaps 1000 yr. Notable hydrologic variability has occurred at all time scales and should continue into the future.

Based on the ceramics analysis, site stratigraphy, radiocarbon dates, and a Correspondence Analysis (CA), two chronological sub-phases were identified and their characteristics described.

This chapter explores the significance of Kant’s engagement with Leibniz for the Transcendental Deduction section of the Critique of Pure Reason. It is argued that the goal of the Transcendental Deduction is largely cosmological—to show that the pure concepts of the understanding relate a priori to objects if it succeeds in showing that human understanding uses these concepts to construct a world out of the appearances that are sensibly given to us in space and time. The notion of “world” that Kant employs in his cosmology has an ancestor, however, in certain views to be found in Leibniz’s philosophy—particularly in his well-known correspondence with Clarke.

Abstract:
How and why can neural activity in general and specifically stimulus-induced activity be associated with consciousness? This is the central question in the present chapter. I suggest a Spatiotemporal model that conceives both brain and consciousness in predominantly Spatiotemporal terms rather than being based on specific contents and their neural processing by the brain. This amounts to a Spatiotemporal theory of consciousness (STC). I discuss two specific Spatiotemporal mechanisms that I deem relevant for consciousness. The first Spatiotemporal mechanism refers to “Spatiotemporal integration and nestedness” that describe how different frequencies/regions are coupled and linked, i.e., integrated, and subsequently contained, i.e., nested, with each other. Again, based on empirical findings, “Spatiotemporal integration and nestedness” may predispose the level/state of consciousness, i.e., NPC. The second Spatiotemporal mechanism consists in “Spatiotemporal expansion” that allows to expand the stimuli’ specific points in time and space beyond itself by the brain’s spontaneous activity and its spatiotemporal structure. Based on various empirical findings, I suggest “Spatiotemporal expansion” a sufficient neural condition of consciousness, i.e., a neural correlate of the content of consciousness (NCC). Both spatiotemporal mechanisms are specific in that they can distinguish consciousness and unconsciousness: there is “Spatiotemporal expansion” rather than “Spatiotemporal constriction” and there is “Spatiotemporal nestedness” rather than “Spatiotemporal isolation”. This illustrates the specificity of the Spatiotemporal mechanisms which argues against what can be described as “argument of non-specificity”. Moreover, the STC is based on Spatiotemporal mechanisms rather than mere Spatiotemporal features which renders our Spatiotemporal model non-trivial which can be put forward against what can be described as “argument of triviality”. Taken together, the Spatiotemporal model of consciousness as suggested in the STC is neither non-specific but specific in empirical terms nor trivial on conceptual-logical, phenomenal, and ontological grounds.

The chapter investigates processes that allowed Jewish merchants in the eighteenth-century Mediterranean area to sustain familial and commercial obligation over time and space. Primarily based on the correspondence of Tunis-based Joseph Franchetti to his sons and associates in Livorno and Smyrna, this investigation shows that the intersection of family and trade was both a constructed practice and a deeply held moral belief. Strategies employed to preserve a feeling of familial commitment and to educate younger relatives – such as the circulation of gifts, the emphatic identification of love with obligation, and the reliance on surrogate kin – are examined alongside parental fears regarding the risks that young merchants away from home could pose to a family’s reputation and credit.

Abstract:
This chapter details the correspondence between the author and the Central Intelligence Agency regarding the release of information in line with the Freedom of Information Act. At the same time the chapter builds on an emerging body of scholarship that examines the relationship between American postwar ascendancy and “cultural diplomacy” in the early years of the Cold War and decolonization. Few studies have considered how the Congress for Cultural Freedom's (CCF) underwriting reshaped and refashioned the global literary landscape, altered the relationships between writers and their publics, and rendered those whom it supported more recognizable figures than others. These practices were conceived as part of an orchestrated imperial effort to occupy a global public space that by 1948 had been largely dominated by the socialist rhetoric of the Communist Information Bureau (Cominform).

Abstract:
The paper presents singularity-free fully-isotropic T1R2-type parallel manipulators (PMs) with three degrees of freedom. The mobile platform has one independent translation (T1) and two rotations (R2). A method is proposed for structural synthesis of fully-isotropic T1R2-type PMs based on the theory of linear transformations. A one-to-one correspondence exists between the actuated joint velocity space and the external velocity space of the moving platform. The Jacobian matrix mapping the two vector spaces of fully-isotropic T1R2-type PMs presented in this paper is the 3x3 identity matrix throughout the entire workspace. The condition number and the determinant of the Jacobian matrix being equal to one, the manipulator performs very well with regard to force and motion transmission capabilities. As far as we are aware, this paper presents for the first time in the literature solutions of singularity-free T1R2-type PMs with decoupled an uncoupled motions, along with the fully-isotropic solutions.

A one-to-one correspondence exists between the actuated joint velocity space and the external velocity space of the moving platform.

Redundant actuation is used to obtain fully-isotropic parallel wrists with three degrees of freedom.

Abstract:
Abstract Film cooling technique is commonly adopted in modern gas turbine engines to protect high-temperature components from erosion and damage caused by thermal stress. To improve film cooling effectiveness, many efficient prediction tools have been developed and have shown promising results, which are helpful for turbine aero-thermal design. For film cooling, evidence has shown that it is strongly affected by the momentum and heat transport in the boundary layer when hot gas and coolant are mixed downstream of the ejection. From the view of resolution accuracy in the boundary layer, structured grids will be the primary choice in fluid domain. However, the high-pressure gas turbine blades usually have several hundreds of cooling holes with different configurations and arrangements. Numerical simulations often face a big challenge in multi-block structured-grid generations when a large number of cooling holes are involved on curved hole-to-mainstream interfaces. Conventional block-splitting and mesh-generation for all holes are quite time-consuming and cumbersome, because the copying, translating and rotating manipulations cannot be applied on curved hole-to-mainstream interfaces directly. To solve these difficulties, this paper presents a novel mesh-generation strategy, which is a background-grid based mapping (BGBM) method, to generate multi-block structured grids for film-cooled blade efficiently without modifying the existing meshing tools and solvers, which is convenient for CFD users. It consists of three main steps: At first, the correspondence between physical space and computational space is established by two sets of background grids. Then, the sectional curves of geometry features in physical space are projected to the computational space. With these treatments, the curved hole-to-mainstream interfaces are flattened in computational space, where grids can be quickly generated with block copying, translating, rotating and merging manipulations. Thereafter, meshes in computational space are mapped back to the physical space based on the correspondence between physical and computational spaces, and high-quality structured-meshes can be obtained for numerical simulations. To demonstrate the presented meshing strategy, several typical cases with film cooling are selected for testing, including single cooling hole on curved surface, multiple rows of cooling holes on curved surface and NASA C3X vane with multiple hole arrays. In these cases, different holes, including the cylindrical holes and shaped holes with different ejection angles and arrangements, on curved interfaces are taken into consideration. The quality of generated structured grids for each test case is illustrated, which is able to meet the requirement of CFD solver. With the generated meshes, conjugate heat transfer performance in the turbine vane with different cooling arrangements is investigated and also validated with the existing experimental data.

Abstract:
This paper proposed a new interaction paradigm in the virtual reality (VR) environments, which consists of a virtual mirror or window projected onto a virtual surface, representing the correct perspective geometry of a mirror or window reflecting the real world. This technique can be applied to various videos, live streaming apps, augmented and virtual reality settings to provide an interactive and immersive user experience. To support such a perspective-accurate representation, we implemented computer vision algorithms for feature detection and correspondence matching. To constrain the solutions, we incorporated an automatically tuning scaling factor upon the homography transform matrix such that each image frame follows a smooth transition with the user in sight. The system is a real-time rendering framework where users can engage their real-life presence with the virtual space.

Abstract:
Diffusion weighted MRI is often used to detect and stage neurodegenerative, malignant and ischemic diseases. The correlation between developing pathology and localized diffusion measurements relies on the design of selective phase encoding pulses that alter the intensity of the acquired signal according to biophysical models of spin diffusion in tissue. The most common approach utilizes a bipolar or Stejskal-Tanner gradient pulse sequence to encode the apparent diffusion coefficient as an exponential, multi-exponential or stretched exponential function of experimentally-controlled parameters. Several studies have investigated the ability of the stretched exponential to provide an improved fit to diffusion-weighted imaging data. These results were recently analyzed by establishing a direct link between water diffusion, as measured using NMR, and fractal structural models of tissues. In this paper we suggest an alternative description for stretched exponential behavior that reflects fractional order dynamics of a generalized Bloch-Torrey equation in either space or time. Such generalizations are the basis for similar anomalous diffusion phenomena observed in optical spectroscopy, polymer dynamics and electrochemistry. Here we demonstrate a correspondence between the detected NMR signal and anomalous diffusional dynamics of water through the Riesz fractional order space derivative and the Caputo form of the fractional order Riemann-Liouville time derivative.

Abstract:
Museums as cultural institutions certainly reflect the sociocultural transformations of the new era and are changing with the new reality. Except for that, a museum is, by definition, an institution of memory, a keeper of history, it is based on adoption: the collection, successiveness and actualisation of past experience. What is perceived as innovation by contemporary society may have historical roots and be an actualisation of innovations of a bygone era. Modern museum development recalls a global project undertaken by Russian avant-garde artists in the early 20th century, and implying the institutional modernisation of museums. This study addresses a project taken on by avant-garde artists for the modernisation of museums in the context of general cultural construction, in cooperation with the Soviet Government. The research methodology is based on a conjunction of a historical study and culturological analysis, primarily the concept of the institutional approach. The study consisted in looking through archival documents: The Fund of the People’s Commissariat for Education and its departments (declarations, provisions, resolutions, decrees, minutes of meetings, correspondence, protocols and statements of estimates, inventory books of the State Museum Fund etc.), personal funds of artists and cultural figures, their theoretical works, articles, correspondence. A holistic inter-disciplinary approach combining historical and culturological analysis with prospects for contemporary sociocultural development and the role of museums is seen as a promising novelty of the research. Russian avantgardism as an artistic and sociocultural phenomenon has remained of great interest for a century. Different studies shed light only on separate aspects of this vast topic in different scientific contexts. The examination of the museum project by avant-garde artists under this study allows us to conclude that they were the first to undertake the institutional modernisation of museums by considering them in the focus of new demands of time and society, innovative programmes as forms of personal initiatives and experiments expressed in the broad public space of artistic culture.

Abstract:
Resumen: Un recorrido por la producción de Le Corbusier evidencia la insistente presencia del cuadrado como base de las composiciones en diversos campos (urbanismo, arquitectura, pintura, mobiliario…) y en diferentes formatos (en planta, alzado y sección, o como marco, módulo y cuadrícula). La presente comunicación realiza un análisis formal (gráfico y simbólico) de sus proyectos y obras, rastreando los modos en que se utiliza el cuadrado permaneciendo en el tiempo como una constante recurrente. Para ello se recorren cuatro áreas temáticas que descienden en escala y en dimensiones: 1) capitolios, 2) museos, 3) pabellones y 4) casas, estudiando una serie de ejemplos en cada área a partir de los planos de la Fundación Le Corbusier, generando discursos que reconstruyen un hilo del tiempo en la evolución de los procesos compositivos. De este modo, se desgrana el empleo del cuadrado, en correspondencia con las áreas de estudio, como: 1º) perímetro de la plaza pública donde insertar las arquitecturas representativas, 2º) marco o caja-fuerte donde encerrar los tesoros artísticos (o sagrados), 3º) volumen cúbico abierto y desmontable y 4º) caja definida por la retícula de la estructura. El cuadrado es siempre un medio y no un fin. Persiste un intento de sugerir algunos de los orígenes en su formación clasicista, sus viajes y sus pinturas. Abstract: A tour through the production of Le Corbusier shows the insistent presence of the square as a basis of compositions in various fields (urban planning, architecture, painting, furniture...) and in different formats (in floor, elevation and profile, or as a theme, module and grid). This communication makes a formal analysis (graphic and symbolic) of its projects and works tracing the different ways to use the square that remains as a recurring constant. We can do it through four thematic areas descending in scale and dimensions: 1) capitols, 2) museums, 3) pavilions and 4) houses, studying a series of examples in each area based on the drawings of the Foundation Le Corbusier, generating speeches that reconstruct a thread of the time in the evolution of the compositional process. In correspondence with the four themes of study, we can discovery the employment of the square as different instruments. First: the square as the perimeter of the public space where to insert the representative architectures. Second: as a frame or safety deposit box where to enclose treasures artistic (or Holy). Third: as a cubic volume open and detachable. Fourth: as box defined by the grid of the structure. The square is always a means and not an end. In addition, there is an attempt to suggest some of the origins in his classic formation, his travels and his paintings. Palabras clave: Le Corbusier, composición, cuadrícula, cuadrado, cuadro, cubo.

Abstract:
For programming the AR tools, interactive objects and creating the markers, the method of fiber spaces (k-space) for modeling of ultrasonic wave propagation in an inhomogeneous medium using coarse grids, with maintaining the required accuracy was used. The algorithm and tools of augmented reality were introduced into the adaptive control system of the pulp gas phase in the iron ore flotation process using a control action on the basis of high-energy ultrasound dynamic effects generated by ultrasonic phased arrays. The tools of augmented reality based on k-space methods allow to facilitate wider adoption of ultrasound technology and visualize the ultra-sound propagation in heterogeneous media by providing a specific correspondence between the ultrasound data acquired in real- time and a sufficiently detailed augmented 3D scene. The tools of augmented reality allow seeing the field of ultrasound propagation, its characteristics, as well as the effect of the dynamic effects of ultrasound on the change in the gas phase during the flotation process.
