Liu, Jingjing. "Anatomy of Gaudi's Curve Architectural Language". Journal of Arts and Humanities 6, n. 7 (20 luglio 2017): 33. http://dx.doi.org/10.18533/journal.v6i7.1204.
Abstract (sommario):
<p>Gaudi was a unique architectural designer at the aspect of architectural design in Art Nouveau. His architectural design has a unique line design, including the external shape curve of Casa Mila being representative. The external shape design of Casa Mila had subverted the external design of traditional architectures. The wave shape of its vertical wall had broken the contemporary traditional aesthetic consciousness of architectures. Thus, the reasons and effects for the curved shape in the external shape design of Casa Mila showing incisively and vividly how subversive and disruptive Casa Mila being are the source of studying its external curve design. During the same period, many architectural designs were also applied to curves in the external shape of the buildings. Therefore, the external shape of curves on Casa Mila is how its architectural design curves standing out are contrasted by curve design applied to other contemporaneous architectures in the period of Art Nouveau. The view of this paper expounds the reason that the curvilinear design of Casa Mila is different from that of other architectures, and the influence of the curvilinear design of Casa Mila in the period of Art Nouveau. This paper starts with the analysis of the architectural curve of Casa Mila. By comparative analysis of curve profile and its curvature in external modeling of "House of the People" and Tassel Hotel, this paper reveals that Gaudi's architectural features have an unique external modeling and conveys that the architectural curve of external shape more abounds in using natural elements of imitation.</p>

Abstract (sommario):
Gamma distribution function can have variety of shapes including single peaked positively skewed graph having unit area under the curve, which perfectly matches the graphical presentation of unit hydrograph. The shape and scale parameters can be evaluated from the observed peak runoff rate and time to peak duration by iterative method. Unit hydrograph assumes uniformly distributed storm over the entire area of the watershed hence, a small experimental watershed of 0.12 sq. km at Zonal Agricultural Research Station, Shenda Park, Kolhapur (India) was considered for the. application of model. In this paper a different approach of evaluation of a and /3 have been given with computer program in C language, which will be more effective in computation of shape and scale parameters of Gamma distribution function for modeling the unit hydrograph and then converting to the direct runoff hydrograph. The results of regeneration of direct runoff hydrograph shows very good fit of the observed and computed peak flow and volume under direct runoff hydrograph. The average values of shape and scale parameters also gave better fit of direct runoff hydrograph.

Abstract (sommario):
AbstractAccurate and temporally consistent modeling of human bodies is essential for a wide range of applications, including character animation, understanding human social behavior, and AR/VR interfaces. Capturing human motion accurately from a monocular image sequence remains challenging; modeling quality is strongly influenced by temporal consistency of the captured body motion. Our work presents an elegant solution to integrating temporal constraints during fitting. This increases both temporal consistency and robustness during optimization. In detail, we derive parameters of a sequence of body models, representing shape and motion of a person. We optimize these parameters over the complete image sequence, fitting a single consistent body shape while imposing temporal consistency on the body motion, assuming body joint trajectories to be linear over short time. Our approach enables the derivation of realistic 3D body models from image sequences, including jaw pose, facial expression, and articulated hands. Our experiments show that our approach accurately estimates body shape and motion, even for challenging movements and poses. Further, we apply it to the particular application of sign language analysis, where accurate and temporally consistent motion modelling is essential, and show that the approach is well-suited to this kind of application.

Abstract (sommario):
The influence of particle shape, orientation, and volume fractions, as well as loading conditions, on the mechanical behavior of Ta particles reinforced with bulk metallic glass matrix composite is investigated in this work. A Matlab program is developed to output the MSC.Patran Command Language (PCL) in order to generate automatically two-dimensional (2D) micromechanical finite element (FE) models, in which particle shapes, locations, orientations, and dimensions are determined through a few random number generators. With the help of the user-defined material subroutine (UMAT) in ABAQUS, an implicit numerical method based on the free volume model has been implemented to describe the mechanical response of bulk metallic glass. A series of computational experiments are performed to study the influence of particle shapes, orientations, volume fractions, and loading conditions of the representative volume cell (RVC) on its composite mechanical properties.

Abstract (sommario):
Introduction. The article deals with phraseological means of modeling gender stereotypes that reflect certain femininity- and masculinity-related peculiarities observed in the Turkic languages. Gender stereotypes are a key category of contemporary gender linguistics. The typological study of gender stereotype modeling phraseological tools across a number of Turkic languages makes it possible to outline some linguistic and cultural features inherent to the phraseological representation of femininity and masculinity in Kazakh, Tatar, Bashkir, Uzbek, and Kyrgyz. Goals. The work seeks to describe linguistic and cultural features of phraseological gender stereotype modeling in the Turkic languages. Materials. The paper focuses on phraseological units contained in various dictionaries of the examined Turkic languages, in particular, phraseological, explanatory and bilingual ones. Results. The study yields a number of key theses as follows: 1) phraseological units serve as linguistic and cultural means of modeling gender stereotypes in the Turkic languages; 2) linguoculturological features of femininity and masculinity are represented in the investigated Turkic languages by various models of phraseological units containing characteristic components of cultural codes; 3) certain Turkic languages have a number of typological similarities and differences in the formation and representation of gender stereotypes, irrespective of actual genealogical connections between corresponding languages; 4) the study of phraseological gender stereotype modeling shall contribute to further development of gender studies and provide deeper insights into the phenomenon of gender in the Turkic worldview. Conclusions. The analysis of phraseological material shows the Turkic languages are distinguished by various ways of gender stereotype modeling, reveals some linguoculturological features of representing femininity and masculinity in genetically related languages characterized by certain similarities and differences in the formation of such stereotypes, contributes to the identification of priority components of linguoculturological codes that shape the peculiarities of gender stereotypes in Turkic languages. A significant part of phraseological units express gender stereotypes through the following components of cultural codes — astronomical, zoomorphic, somatic, vestimentary, gastronomic, color and physical ones — that are characteristic of each language and gender separately.

Abstract (sommario):
This study investigated the method of Shape Grammar to develop a computational technique to generate spatial configuration at the early stage of the design process. In synthesizing the spatial configuration and its variants, the user (i.e., architect) can use this tool as a heuristic way to select and choose a spatial configuration of geometric shapes to represent functional requirements and their relationships. We studied the example of Adolf Loos's residential works as our basis for the parametric shape rules and the tool developed in the form of a modular cluster component in the Visual Programming Language Grasshopper in a Rhinoceros 3D modeling software. This cluster component, termed "Rupa," is parametrically modeled and consists of two main algorithms: 1) two-dimensional and three-dimensional rules-based shape generation and 2) the transformation rules of translation, rotation, reflection, dilatation, and tension. Using this component, the user can create and transform a shape configuration by its parameters, constrained only by the characteristics of Adolf Loos's residential works design rules as the underlying principles behind the component. Although limited only to three of Loos's residential works, this experiment has successfully generated residential spatial configuration designs based on the constraint rules of Adolf Loos's residential works. The early results show the potential of this method and tool in aiding architects to create design variants and select those that are the most optimal.

Abstract (sommario):
In this paper, we propose a 3D object recognition approach, based on the shape distribution D2 and artificial neural networks. The challenge is to discriminate between similar and dissimilar shapes by finding a shape signature that can be constructed and classified quickly. We propose a connectionist system to recognize 3D objects in VRML (Virtual Reality Modeling Language) format. The key idea is to represent the signature of an object as a shape distribution sampled from a shape function measuring global geometric properties of an object. The proposed strategy is the following: from a polygon object to be recognized, a triangulation is performed. Then, distances are calculated between two random points of the triangulated surface of the 3D object. The frequency of these distances will be represented by a normalized histogram. The values of these histograms feed a multi-layer neural network with back- propagation training. We demonstrate the potential of this approach in a set of experiments, which proved our system could achieve above 91.7% recognition rate. In addition, to evaluate the efficiency of our method, we compare our classifier with Support vector machine and k- nearest neighbours. The simulation results highlight the performance of the proposed approach.

Abstract (sommario):
New techniques involving three-dimensional (3D) data collection and landmark analysis provide an opportunity to make considerable advances in understanding blastoid morphology. This pilot study examines four species (Pentremites pyriformis, P. tulipaformis, P. fredericki n. sp. and P. meganae n. sp.) using 3D morphological variation and geometric morphometrics to discriminate between species. All specimens were collected from a single shale unit within the Upper Mississippian Glen Dean Formation near Hopkinsville, Kentucky. A 3D laser scanner was used to acquire 3D images for all specimens. Conservative blastoid thecal plating allowed the collection of 3D coordinates for a series of homologous landmarks from these laser images that fully describe specimen morphology. Data were analyzed using the R (language and environment for statistical computing and graphics) packages SHAPES and MCLUST. Mixture modeling identified and separated all four species based on shape alone. In addition, three new species were discovered during this study, including: Pentremites fredericki, P. meganae and Diploblastus fadigai.

"Topological data analysis reveals core heteroblastic and ontogenetic programs embedded in leaves of grapevine (Vitaceae) and maracuyá (Passifloraceae)". PLOS Computational Biology 20, n. 2 (5 febbraio 2024): e1011845. http://dx.doi.org/10.1371/journal.pcbi.1011845.
Abstract (sommario):
Leaves are often described in language that evokes a single shape. However, embedded in that descriptor is a multitude of latent shapes arising from evolutionary, developmental, environmental, and other effects. These confounded effects manifest at distinct developmental time points and evolve at different tempos. Here, revisiting datasets comprised of thousands of leaves of vining grapevine (Vitaceae) and maracuyá (Passifloraceae) species, we apply a technique from the mathematical field of topological data analysis to comparatively visualize the structure of heteroblastic and ontogenetic effects on leaf shape in each group. Consistent with a morphologically closer relationship, members of the grapevine dataset possess strong core heteroblasty and ontogenetic programs with little deviation between species. Remarkably, we found that most members of the maracuyá family also share core heteroblasty and ontogenetic programs despite dramatic species-to-species leaf shape differences. This conservation was not initially detected using traditional analyses such as principal component analysis or linear discriminant analysis. We also identify two morphotypes of maracuyá that deviate from the core structure, suggesting the evolution of new developmental properties in this phylogenetically distinct sub-group. Our findings illustrate how topological data analysis can be used to disentangle previously confounded developmental and evolutionary effects to visualize latent shapes and hidden relationships, even ones embedded in complex, high-dimensional datasets.

Abstract (sommario):
The article is devoted to the development of intelligent monitoring systems of technological processes based on the use of machine vision systems. The principles of object-oriented formalization of the process of designing information technology of the classification of objects by the geometric shape of the image obtained from the machine vision system are proposed in the article. The proposed information technology is based on the use of machine learning technologies and provides for the selection of the best structure of the classifier model from a set of candidate models. Construction of candidate models is based on the use of the group method of data handling, based on the principles of self-organization of models. The outline of the image of the object obtained from the intelligent monitoring system is the input information. The set of input data contains a set of morphometric parameters that describe the geometric shape of the figure formed by the contour of the image of the object, as well as the label of the class to which the object belongs. The formation of the set of input data is implemented in the block «Image Processing». The decisive rule of classification is built in the block of synthesis of models of information technology of classification. GMDH neural networks were used as an algorithm for model synthesis. The choice of the best structure of the model is performed by a set of criteria. The information technology for constructing the classifier model is implemented by supplementing the block of algorithms for synthesis of MSUA models with the block «Class of models», which implements the process of selecting the class of functions for building models, and the block «Verification of models», which implements the best model structure. Construction of the meta-model of the design process was performed using a unified modeling language. The functional meta-model is represented by a use case diagram.

Abstract (sommario):
Building computer models of dynamic canal surfaces is a special case when implemented in CAD-systems since existing methods of surface modeling of such type are concentrated mostly on obtaining analytical expressions such as equations for the surface itself or its sections. The article introduces a constructive method of building models based on plane and spatial geometric constructions. The paper provides the analysis of given surface parameters, constructive algorithms for setting up a geometric correspondence between the graph of the cross-sectional area and the directrix, constructing of cross-section for the given point on the cross-section area graph as well as placement the cross-sections in three dimensions and determining spatial coordinates of the points on the surface. This allows to build a structured point cloud of a dynamic canal surface of required density and build a model of it in CAD-systems. Suggested constructive algorithms are applied with the help of GC language commands. The paper provides fragments of construction subroutines as well as examples of created models of dynamic canal surfaces. The approach proposed provides for automation of building models of surfaces in CAD-systems, moreover it is flexible to adjust according to the given parameters such as a directrix shape, cross-section area graph, a cross-section shape, etc.

Abstract (sommario):
In the demonstration phase of a missile scheme, to obtain the optimum proposal, designers need to modify the parameters of the overall structure frequently and significantly, and perform the structural analysis repeatedly. In order to reduce the manual workload and improve the efficiency of research and development, a general integrated method of missile structure modeling, analysis and optimization was proposed. First, CST (Class and Shape transformation functions) parametric method was used to describe the general structure of the missile. The corresponding software geometric modeling and FEM (Finite Element Method) analyzing of the missile were developed in C/C++ language on the basis of the CST parametric method and UG (Unigraphics) secondary development technology. Subsequently, a novel surrogate model-based optimation strategy was proposed to obtain a relatively light mass missile structure under existing shape size. Eventually, different missile models were used to verify the validity of the method. After executing the structure modeling, analysis and optimization modules, satisfactory results can be obtained that demonstrated the stability and adaptability of the proposed method. The method presented saves plenty of time comparing to the traditional manual modeling and analysis method, which provides a valuable technique to improve the efficiency of research and development.

Abstract (sommario):
Marine propeller is a kind of typical part with free-form surface. The surface shape of propeller blade is very complex, and it is difficult to be described by general mathematical expressions, so that the modeling of propeller is very cumbersome and error-prone. To solve this problem, firstly, three-dimensional point data of propeller blade is calculated by VC/MFC programming technology and access technology of database based on projection principle of propeller blade. And then, automation and parameterization of solid modeling for propeller of different map forms are realized by programming with the interactive programming language of UG/Open Grip based on UG software. The parametric modeling system provides accurate three-dimensional model for automatic programming, dynamic simulation and numerical analysis of propeller, and improves the design efficiency of systematic propeller, and has very good practical value.

Abstract (sommario):
Abstract The present issue of Chinese Semiotic Studies is published in memory of Thomas A. Sebeok. Sebeok was not only a master semiotician, but more importantly a grand artist in semiotics. As one of the most important contemporary figures in semiotics, linguistics, ethnology, and cultural studies, Sebeok made profound contributions to the progress of global semiotics through his distinguished theoretical achievements and promotional activities. His works have proven to be so relevant that they continue to exert a determinative influence and provide directions for the development of semiotics and its many subdivisions, especially biosemiotics, beyond the 20th century. Now, 21 years into the present century, during which semiotic studies around the world have made remarkable progress, it is about time to highlight some specific ways in which his contributions will continue to shape and guide semiotic studies, demonstrating the relevance of these contributions to the 21st century challenges. To this end, this special issue presents some up-to-date and informed studies that explore Sebeok’s contributions to semiotics and their vital implications for fundamental problems relevant to humanity as a semiotic animal in the present day and in the rest of this century and beyond.

Abstract (sommario):
Abstract Development of self-compacting concrete (SCC) is a very desirable achievement in the reinforced concrete (RC) structures for overcoming issues associated with many problems such as congestions of steel reinforcement. This non-vibrating concrete is not affected by the skill of workers, and the shape and amount of reinforcing bar arrangement of a structure. Due to the high fluidity and resisting power of reinforcing of SCC, it can be pumped longer distances. In this study, the finite element (FE) modeling of three SCC beams in shear while taking into account, the flexural tensile strength of concrete is computed and the results are compared with the available experimental tested reinforced SCC beams. The stirrups are located at 75 mm apart from the end of beams up to the loading point. The electrical strain gauges (ESGs) have been embedded on the stirrups and their strain readings are taken for every step of load increment. For modeling longitudinal steel reinforcing bars and concrete, the 3-D elements with 2-node and 8-node, are used respectively. The comparison of results obtained by two methods is indicated that a good satisfactory agreement is achieved.

Abstract (sommario):
Lectometry is a corpus-based methodology that explores how multiple language-external dimensions shape language usage in an aggregate perspective. The paper combines this methodology with Semantic Vector Space modeling to investigate lexical variability in written Standard English, as sampled in the original Brown family of corpora (Brown, LOB, Frown and F-LOB). Based on a joint analysis of 303 lexical variables, which are semi-automatically extracted by means of a SVS, we find that lexical variation in the Brown family is systematically related to three lectal dimensions: discourse type (informative versus imaginative), standard variety (British English versus American English), and time period (1960s versus 1990s). It turns out that most lexical variables are sensitive to at least one of these three language-external dimensions, yet not every dimension has dedicated lexical variables: in particular, distinctive lexical variables for the real time dimension fail to emerge.

Abstract (sommario):
Informal English learning plays a crucial role in vocabulary learning, yet few scholars have explored the use of large language models for this purpose. In light of this, our study, integrating Self-Determination Theory (SDT) and the Unified Theory of Acceptance and Use of Technology (UTAUT), employed Structural Equation Modeling (SEM) to investigate factors influencing 568 Chinese English learners’ use of large language models for vocabulary learning. Our findings identified six significant factors from those models—perceived autonomy, perceived competence, perceived relatedness, performance expectancy, effort expectancy, and social influence—that significantly shape learners’ intentions and behaviors towards utilizing large language models for vocabulary learning. Notably, effort expectancy emerged as the most influential factor, while facilitating conditions did not significantly impact usage intentions. This research offers insights for future curriculum design and policy formulation, highlighting the importance of understanding learners’ perspectives on technology use in education.

Abstract (sommario):
This article examines the potential influence of iconic characters—villains of mass culture—on destructive and aggressive youth behavior. The cultivation of certain societal groups and individual media characters can lead to the normalization of hostility and violence. This study analyzes the communication styles, intelligence, motives, aggression levels, and violent actions of famous villains from films, television, and literature. Particular attention is paid to the Joker’s communicative behavior, dialogues, and language, examining how he psychologically manipulates others and conveys his destructive views through unconventional techniques. Using textual examples from comic books and films, it analyzes how the Joker’s language choices and performative style reflect his background and moral-anarchic worldview. His rhetoric provokes violent reactions from allies and enemies alike, highlighting his ability to destabilize situations. The presented portrait reveals a multi-layered understanding of this legendary creation in different epochs and contexts. The findings indicate certain villain traits that could potentially encourage impressionable youth to engage in harmful behavior. Overall, provocative fiction has a double-edged significance as it can both shape and mislead developing minds. Recommendations are made to reduce the negative effects of glamorizing villains in entertainment media.

Abstract (sommario):
Language interfaces with many other cognitive domains. This paper explores how interactions at these interfaces can be studied with deep learning methods, focusing on the relation between language emergence and visual perception. To model the emergence of language, a sender and a receiver agent are trained on a reference game. The agents are implemented as deep neural networks, with dedicated vision and language modules. Motivated by the mutual influence between language and perception in cognition, we apply systematic manipulations to the agents’ (i) visual representations, to analyze the effects on emergent communication, and (ii) communication protocols, to analyze the effects on visual representations. Our analyses show that perceptual biases shape semantic categorization and communicative content. Conversely, if the communication protocol partitions object space along certain attributes, agents learn to represent visual information about these attributes more accurately, and the representations of communication partners align. Finally, an evolutionary analysis suggests that visual representations may be shaped in part to facilitate the communication of environmentally relevant distinctions. Aside from accounting for co-adaptation effects between language and perception, our results point out ways to modulate and improve visual representation learning and emergent communication in artificial agents.

Abstract (sommario):
he use of vibration transport in agricultural production plays a very significant part. Vibratory conveyors have the variety of advantages over traditional transporting ma-chines such as auger and belt type conveyors used at agri-cultural enterprises for transporting mainly loose and granular materials. A rather low wear coefficient of trans-porting body itself - a conveying trough of a vibration-transporting machine may be referred to the advantages, besides, in some constructions of vibration-transporting machines the amount of friction couples is reduced to a minimum. In the design of constructions of vibration-transporting machines a question arises about the determi-nation of motion mode of particles of the transporting mate-rial. Thus, the detection of a predominant component of motion will allow forecasting the wear rate of a transporting surface and the possibility of enlarging the field of techno-logical use of vibration-transporting machines. During the research process for the determination of motion mode of grain material the shape of which was close to spheroid and ellipsoid, the method of mathematical modeling was applied. The system of differential equations of second order was compiled and solved. In the equations the influ-ence of vibration of a transporting surface on the motion of an elliptically shaped body was taken into account. To solve the system the classical method - Runge-Kutta method of the fourth order was used. The program devel-oped in programming language Python allowed identifying the motion mode of the bodies of spheroidal and ellipsoidal shapes on a vibrating surface. As the result, it was deter-mined that the motion of a body of a spheroidal shape on a vibrating surface was possible due to rolling, and the mo-tion of a body of an ellipsoidal shape was achieved be-cause of its sliding on the surface, what follows from wan-ing rotating movements. The suggested method for the determination of motion mode of a body on a vibrating sur-face is rather flexible and may be applied in calculation for larger bodies in comparison with grain seeds.

Abstract (sommario):
Recent advances in cultural analytics and large-scale computational studies of art, literature and film often show that long-term change in the features of artistic works happens gradually. These findings suggest that conservative forces that shape creative domains might be underestimated. To this end, we provide the first large-scale formal evidence of the association between poetic meter and semantics in 18-19th century European literatures, using Czech, German and Russian collections with additional data from English poetry and early modern Dutch songs. Our study traces this association through a series of unsupervised classifications using the abstracted semantic features of poems that are inferred for individual texts with the aid of topic modeling. Topics alone enable recognition of the meters in each observed language, as may be seen from the same-meter samples clustering together (median Adjusted Rand Index between 0.48 and 1 across traditions). In addition, this study shows that the strength of the association between form and meaning tends to decrease over time. This may reflect a shift in aesthetic conventions between the 18th and 19th centuries as individual innovation was increasingly favored in literature. Despite this decline, it remains possible to recognize semantics of the meters from past or future, which suggests the continuity in meter-meaning relationships while also revealing the historical variability of conditions across languages. This paper argues that distinct metrical forms, which are often copied in a language over centuries, also maintain long-term semantic inertia in poetry. Our findings highlight the role of the formal features of cultural items in influencing the pace and shape of cultural evolution.

Abstract (sommario):
Multi-scale modeling of complex biological systems remains a central challenge in the systems biology community. A method of dynamic knowledge representation known as agent-based modeling enables the study of higher level behavior emerging from discrete events performed by individual components. With the advancement of computer technology, agent-based modeling has emerged as an innovative technique to model the complexities of systems biology. In this work, the authors describe SPARK (Simple Platform for Agent-based Representation of Knowledge), a framework for agent-based modeling specifically designed for systems-level biomedical model development. SPARK is a stand-alone application written in Java. It provides a user-friendly interface, and a simple programming language for developing Agent-Based Models (ABMs). SPARK has the following features specialized for modeling biomedical systems: 1) continuous space that can simulate real physical space; 2) flexible agent size and shape that can represent the relative proportions of various cell types; 3) multiple spaces that can concurrently simulate and visualize multiple scales in biomedical models; 4) a convenient graphical user interface. Existing ABMs of diabetic foot ulcers and acute inflammation were implemented in SPARK. Models of identical complexity were run in both NetLogo and SPARK; the SPARK-based models ran two to three times faster.

Abstract (sommario):
At present, warp-knitted yarn-dyed shirt fabric has become the research focus due to its comfort and highly efficient production. In order to shorten the development process of warp-knitted yarn-dyed shirt fabric, a computing method including theoretical modeling and simulation is proposed in this paper to simulate 2–5 guide bar warp-knitted yarn-dyed shirt fabric. Based on the structure model of warp-knitted fabric, a new model of geometric shape, including loops and underlap, is built according to size measurement results of the loops. In terms of the establishment of mathematical models, such as models of yarn-pressing, loop types, loop locations, guide bar threading, color and fineness, the transformation between knitting technology and mathematical language is realized. With the double buffer technique of HTML (Hypertext Markup Language), loops and underlaps of each bar are displayed separately on different canvases superposed in some order. Simulation is implemented for 2–5 bar warp-knitted yarn-dyed shirt fabric via JavaScript and C# programming languages. The results indicate that this method is able to simulate diverse 2–5 bar warp-knitted yarn-dyed shirt fabrics in a short time. The pattern effect can be seen with a high similarity and practicability before it is produced, thereby shortening the development.

Abstract (sommario):
The uneven cognitive phenotype in the adult outcome of Williams syndrome has led some researchers to make strong claims about the modularity of the brain and the purported genetically determined, innate specification of cognitive modules. Such arguments have particularly been marshaled with respect to language. We challenge this direct generalization from adult phenotypic outcomes to genetic specification and consider instead how genetic disorders provide clues to the constraints on plasticity that shape the outcome of development. We specifically examine behavioral studies, brain imaging, and computational modeling of language in Williams syndrome but contend that our theoretical arguments apply equally to other cognitive domains and other developmental disorders. While acknowledging that selective deficits in normal adult patients might justify claims about cognitive modularity, we question whether similar, seemingly selective deficits found in genetic disorders can be used to argue that such cognitive modules are prespecified in infant brains. Cognitive modules are, in our view, the outcome of development, not its starting point. We note that most work on genetic disorders ignores one vital factor, the actual process of ontogenetic development, and argue that it is vital to view genetic disorders as proceeding under different neurocomputational constraints, not as demonstrations of static modularity.

Abstract (sommario):
This essay contributes to a history of evolutionary models of media shift through a reading of Daniel Defoe. Published in 1722 but depicting events of 1664–65, A Journal of the Plague Year represents temporal distance in terms of shifts in modes of communication. Modes that in reality are coexistent and interdependent are here represented as parts of a linear, progressive development. Defoe helped shape an emergent hierarchy of media forms with print at its apex. A key structuring binary of this text opposes a backward past associated with orality to a new, print-oriented modernity linked to the collection and reproduction of accurate statistics and true report. The essay first examines Defoe's handling of the “Women-Searchers”–agents employed to search bodies to determine cause of death, whose oral reports formed the basis for the printed bills of mortality–then considers the depiction of rumors and an oral street culture that is associated with old women, error, and contagious superstition.

Abstract (sommario):
CAD modeling, despite being the industry-standard, remains restricted to usage by skilled practitioners due to two key barriers. First, the user must be able to mentally parse a final shape into a valid sequence of supported CAD commands; and second, the user must be sufficiently conversant with CAD software packages to be able to execute the corresponding CAD commands. As a step towards addressing both these challenges, we present Free2CAD wherein the user can simply sketch the final shape and our system parses the input strokes into a sequence of commands expressed in a simplified CAD language. When executed, these commands reproduce the sketched object. Technically, we cast sketch-based CAD modeling as a sequence-to-sequence translation problem, for which we leverage the powerful Transformers neural network architecture. Given the sequence of pen strokes as input, we introduce the new task of grouping strokes that correspond to individual CAD operations. We combine stroke grouping with geometric fitting of the operation parameters, such that intermediate groups are geometrically corrected before being reused, as context, for subsequent steps in the sequence inference. Although trained on synthetically-generated data, we demonstrate that Free2CAD generalizes to sketches created from real-world CAD models as well as to sketches drawn by novice users. Code and data are at https://github.com/Enigma-li/Free2CAD.

Abstract (sommario):
Abstract The paper describes the educational discipline “Geometric modeling”, which is suitable for students of applied mathematics. The course covers spline representations and transfinite interpolation methods for modeling the shape of geometric objects, the methods for performing Boolean operations between objects and methods for visualizing the objects. Screenshots of some graphic windows of the developed visualization programs for supporting the implementation of individual assignments in the course are shown. The programs have web interfaces that use the WebGL graphics API in a browser, independent of an operating system, and are also available for smartphones and tablets. They provide graphical output for curves and surfaces in three-dimensional space, user interfaces for entering the initial data and interaction with geometric objects. Students only need to write their own calculation code for the programs in the JavaScript programming language. The interactive tools enable students to get practical skills in working with splines and visually analyze the impact of the input data on the final geometry. The individual assignments and programs are specially focused to stimulate students’ interests. The paper is addressed to teachers of the geometric modeling for mathematicians and computer scientists. It seems to be interesting to those who develop software interfaces for geometric modeling algorithms.

Abstract (sommario):
Bulgaro-Tatar epigraphic monuments of the 13th–17th centuries with graceful calligraphic Arabic writing and peculiar floral ornamentation are unique evidence of history of the Tatars. Epitaphs are not only the last tribute to a dead person, first of all they served and serve living people, referring to their memory, feelings and attitude of a person towards their ancestors, their past. Documenting these monuments is important process of preserving the heritage for posterity. Many monuments studied in the middle of the 20th century were not physically preserved or the inscriptions were completely destroyed. The question of preservation and protection of this type of cultural heritage is so acute. The study of epitaphs at the modern methodological level involves virtual museumification, 3D-modeling, cataloging, deciphering and reading, as well as assessing the risks of their destruction using modern, relevant approaches to study of historical and cultural heritage. In this study, surveys of epigraphic monuments were carried out for the first time at modern level. By high-precision photogrammetric surveys and 3D-modeling, it was possible to obtain digital copies of objects, which makes it possible to determine changes in shape, restore the shape of lost objects using archival data. To organizing convenient access to spatial information for many users, the results of research are presented on a thematic web resource and a geoportal. The main functionality of such web GIS, in addition to directly displaying interactive spatial information, is the ability to make user queries, measure objects and provide access to related multimedia materials.

Abstract (sommario):
Biometric identification systems use given parameters and function on the basis of Colored Petri Nets as a modelling language developed for systems in which communication, synchronization and distributed resources play an important role. Colored Petri Nets combine the strengths of Classical Petri Nets with the power of a high-level programming language. Coloured Petri Nets have both, formal intuitive and graphical presentations. Graphical CPN model consists of a set of interacting modules which include a network of places, transitions and arcs. Mathematical representation has a well-defined syntax and semantics, as well as defines system behavioural properties. One of the best known features used in biometric is the human finger print pattern. During the last decade other human features have become of interest, such as iris-based or face recognition. The objective of this paper is to introduce the fundamental concepts of Petri Nets in relation to tooth shape analysis. Biometric identification systems functioning has two phases: data enrollment phase and identification phase. During the data enrollment phase images of teeth are added to database. This record contains enrollment data as a noisy version of the biometrical data corresponding to the individual. During the identification phase an unknown individual is observed again and is compared to the enrollment data in the database and then system estimates the individual. The purpose of modeling biometric identification system by means of Petri Nets is to reveal the following aspects of the functioning model: the efficiency of the model, behavior of the model, mistakes and accidents in the model, feasibility of the model simplification or substitution of its separate components for more effective components without interfering system functioning. The results of biometric identification system modeling and evaluating are presented and discussed.

Abstract (sommario):
Research work is aimed at modeling the process of milling surfaces of complex shape in automated CAD/CAM systems. To reduce labour input of this process, an algorithm for designing milling operations is proposed. The algorithm is implemented in the form of software written in the VBA programming language from Office Excel. The software allows to select cutting tools and cutting modes for roughing, semi-finishing and finishing milling. The initial data for this are: processed material, part configuration, profile depth, technical requirements on the surface. The work of the algorithm was tested on the parts of the mold type. It is found that the set of cutting tools for all types of milling surfaces of complex shape is selected taking into account the overall dimensions of the treated surface, its curvature and radii of surfaces rounding. The results of simulation of mold processing in Sprut CAM system according to the assigned set of cutting tools and cutting modes allowed to choose the tool path with minimal processing time.

Abstract (sommario):
ABSTRACTWe present a hierarchical Bayesian framework for modeling the acquisition of verb argument constructions. It embodies a domain-general approach to learning higher-level knowledge in the form of inductive constraints (or overhypotheses), and has been used to explain other aspects of language development such as the shape bias in learning object names. Here, we demonstrate that the same model captures several phenomena in the acquisition of verb constructions. Our model, like adults in a series of artificial language learning experiments, makes inferences about the distributional statistics of verbs on several levels of abstraction simultaneously. It also produces the qualitative learning patterns displayed by children over the time course of acquisition. These results suggest that the patterns of generalization observed in both children and adults could emerge from basic assumptions about the nature of learning. They also provide an example of a broad class of computational approaches that can resolve Baker's Paradox.

Abstract (sommario):
With the recent advancement of smartphone technology in the past few years, smartphone usage has increased on a tremendous scale due to its portability and ability to perform many daily life tasks. As a result, smartphones have become one of the most valuable targets for hackers to perform cyberattacks, since the smartphone can contain individuals’ sensitive data. Smartphones are embedded with highly accurate sensors. This article proposes BetaLogger , an Android-based application that highlights the issue of leaking smartphone users’ privacy using smartphone hardware sensors (accelerometer, magnetometer, and gyroscope). BetaLogger efficiently infers the typed text (long or short) on a smartphone keyboard using Language Modeling and a Dense Multi-layer Neural Network (DMNN). BetaLogger is composed of two major phases: In the first phase, Text Inference Vector is given as input to the DMNN model to predict the target labels comprising the alphabet, and in the second phase, sequence generator module generate the output sequence in the shape of a continuous sentence. The outcomes demonstrate that BetaLogger generates highly accurate short and long sentences, and it effectively enhances the inference rate in comparison with conventional machine learning algorithms and state-of-the-art studies.

Abstract (sommario):
Speech is a perceptuo-motor system. A natural computational modeling framework is provided by cognitive robotics, or more precisely speech robotics, which is also based on embodiment, multimodality, development, and interaction. This paper describes the bases of a virtual baby robot which consists in an articulatory model that integrates the non-uniform growth of the vocal tract, a set of sensors, and a learning model. The articulatory model delivers sagittal contour, lip shape and acoustic formants from seven input parameters that characterize the configurations of the jaw, the tongue, the lips and the larynx. To simulate the growth of the vocal tract from birth to adulthood, a process modifies the longitudinal dimension of the vocal tract shape as a function of age. The auditory system of the robot comprises a “phasic” system for event detection over time, and a “tonic” system to track formants. The model of visual perception specifies the basic lips characteristics: height, width, area and protrusion. The orosensorial channel, which provides the tactile sensation on the lips, the tongue and the palate, is elaborated as a model for the prediction of tongue-palatal contacts from articulatory commands. Learning involves Bayesian programming, in which there are two phases: (i) specification of the variables, decomposition of the joint distribution and identification of the free parameters through exploration of a learning set, and (ii) utilization which relies on questions about the joint distribution. Two studies were performed with this system. Each of them focused on one of the two basic mechanisms, which ought to be at work in the initial periods of speech acquisition, namely vocal exploration and vocal imitation. The first study attempted to assess infants’ motor skills before and at the beginning of canonical babbling. It used the model to infer the acoustic regions, the articulatory degrees of freedom and the vocal tract shapes that are the likeliest explored by actual infants according to their vocalizations. Subsequently, the aim was to simulate data reported in the literature on early vocal imitation, in order to test whether and how the robot was able to reproduce them and to gain some insights into the actual cognitive representations that might be involved in this behavior. Speech modeling in a robotics framework should contribute to a computational approach of sensori-motor interactions in speech communication, which seems crucial for future progress in the study of speech and language ontogeny and phylogeny.

Abstract (sommario):
A multiple case study was conducted over the duration of six months to assess the effectiveness of video modeling intervention in teaching social behaviors. A group of 20 children with Asperger Syndrome or High Functioning Au-tism were selected from mainstream public school. Each child watched a videotape demonstrating a targeted be-havior by a typically developing peer or a video of them-selves modeling the appropriate behavior. The child was then asked to engage in a social situation demanding the use of previously taught behavior. A special education teacher, classroom teacher, and speech-language pathologist rated the child’s interaction and use of target-ed behaviors. Videos were used to modify, teach or shape a target behavior for the child to imitate and learn. For the purpose of this study, three specific behaviors were taught: teaching compliment giving, initiations, maintain-ing conversations, and learning and obeying classroom rules. Results of this study indicated that video modeling is an effective intervention method in teaching social behav-iors to children on the Autism Spectrum. All participants showed an increased use of targeted social behaviors and also attempted to generate behaviors regardless of target-ed stimuli. Further research in using adults as models and targeting various social behaviors is warranted Keywords: Autism, Asperger syndrome, High-Functioning Autism, Social Interaction, Video Model, Social Behaviors

Abstract (sommario):
The extent to which word learning is delayed by maturation as opposed to accumulating data is a longstanding question in language acquisition. Further, the precise way in which data influence learning on a large scale is unknown—experimental results reveal that children can rapidly learn words from single instances as well as by aggregating ambiguous information across multiple situations. We analyze Wordbank, a large cross-linguistic dataset of word acquisition norms, using a statistical waiting time model to quantify the role of data in early language learning, building off Hidaka ( 2013 ). We find that the model both fits and accurately predicts the shape of children’s growth curves. Further analyses of model parameters suggest a primarily data-driven account of early word learning. The parameters of the model directly characterize both the amount of data required and the rate at which informative data occurs. With high statistical certainty, words require on the order of ∼ 10 learning instances, which occur on average once every two months. Our method is extremely simple, statistically principled, and broadly applicable to modeling data-driven learning effects in development.

Abstract (sommario):
Орнамент, зародившись в древней культуре, имел ритуально-магическое значение, был символическим отражением действительности. В гармонично выполненных орнаментах, являющихся народным достоянием, отображаются история, традиции, обычаи и быт народа. Казахский национальный орнамент ведет свою историю из глубокой древности как наследие андроновской культуры бронзового века. Первоначальный сакральный смысл узоров орнамента был в значительной мере утрачен. Однако значение орнаментального искусства в повседневной жизни народа было искажено не столь значительно. Орнаментальное искусство можно рассматривать как вполне самостоятельный вид художественного творчества, выражающий концептуальное мышление его создателя. Это своего рода летопись знакового средства. Национальный орнамент позволяет проследить процесс этногенеза народа и выделить его этнографические особенности. Математические методы исследования орнамента начали применяться в конце ХХ века и показали себя довольно эффективным средством. В данной работе выполнено системное исследование орнамента в комплексе с его основой – сеткой (решеткой), на которой он строится. Объектом исследования выбран традиционный войлочный казахский ковер. Он обычно прямоугольный, в центральной части размещается симметричный рисунок, окантованный бордюром. В орнаменте, помимо геометрической симметрии, присутствует и физическая симметрия (симметрия цвета) в отношении как розеток, так и бордюров. При этом цветовая гамма обычно невелика, всего 2–3 цвета, но каждый из них несет свой определенный смысл. Методика исследования была основана на применении законов симметрии, в частности принципа Кюри. Показано, как с изменением мировоззрения человека изменился и понимаемый им смысл орнамента. Проведен анализ мотивов и бордюра орнамента и установлены сетки, на которых они были выполнены. Установлено соответствие местоположения типов элементов орнамента с особыми точками на сетке, имеющими специфические симметрийные свойства по сравнению со всем орнаментальным полем. Подтверждена роль невидимой подложки (сетки, решетки) для построения орнаментов. Ornament is one of the oldest methods of decoration, with the help of which people often tried to express their emotions, knowledge, beliefs, hopes, desires, and requests. Ornamental art can undoubtedly be considered as a completely independent type of applied arts, visualizing the conceptual thinking of its creator at a given moment in time. Therefore, the development of ornament is closely related to the history of the formation and development of the nations of the world. This article considers such a formation on the basis of traditional Kazakh felt carpets of different types, regardless of their manufacture method and purpose. The traditional shape of the carpet is most often a rectangle with a central symmetrical pattern edged with an ornamental curb. In the study of ornaments of traditional Kazakh felt carpets, attention is focused on the symbolism and conceptual meaning of Kazakh ornaments, borders and rosettes in particular. The work is based on a study of the national Kazakh ornament due to its dominant position in the visual arts of this country until the end of the 18th – early 19th centuries, as a result of the semi-nomadic way of life with its inherent unity with the outside world, as well as due to the gradual penetration of Islam with its ban on images of humans and animals. The study is also based on the laws of symmetry, on Curie’s principle in particular. As it was established, the most common methods of constructing curbs of Kazakh felt carpets are: the use of the sliding reflection operation and various combinations of the transfer axis. Also, when creating an ornament, attention is paid to the structure of the substrate - an invisible flat grid (lattice). The ornaments were explored as a single unit rather than its individual elements. Special attention was also paid to the fact that, in the Kazakh folk ornament, along with the shape, its color scheme plays a huge role. Although the value of color is noted in many works, a comprehensive analysis of motifs, background, and substrate has not been carried out. Physical symmetry (that of color) in the Kazakh ornament is no less important than the motif. In this work, the value of color in the life of Turkic peoples, which had been formed in the conditions of nomadic life in the endless steppes, was invested in the consideration of color design. Color for the nomad became not only a hallmark, it could also mean the directions of the world or characterized the quality of the object. As a result, the location of the types of elements of the ornament was determined with special points on the grid that have specific properties compared to the entire ornamental field. The role of an invisible substrate (grid, lattice) for building ornaments was confirmed. Such a mathematical analysis opens up great opportunities in the applied use of the results of this study.
