Resumen Los diagramas de estructura fueron definidos por Warren H Taylor Jr y H. Gill Milton para diseños experimentales balanceados estándar. El método requiere reconocer las características del conjunto de factores que son usados en interacción o anidamiento. El cuadrado medio esperado, el F Ratio y los componentes estimados de varianza pueden derivarse empleando la simbología de los diagramas de estructura. El diagrama de estructura facilita entender el diseño de clasificación experimental y las hipótesis asociadas con dicho modelo, es una representación visual que permite entender las relaciones o interacciones existentes entre los factores seleccionados por el investigador Summary Diagrams of structure were defined by Taylor Jr and Milton for standard experimental balanced designs. The method requires recognizing the characteristics of the set of factors used in the interaction or nested. The expected main square, the F Ratio and the estimated variance components can be driven by using diagrams of structure symbols. Diagram of structure facilitates understanding the design of experimental classification and hypotheses associated with the above mentioned model, it is a visual representation that allows understanding the relationship or existing interactions between the factors selected by the researcher.

Abstract Scientists use diagrams not just to visualize objects and relations in their fields, both empirical and theoretical, but to reason with them as tools of their science. While the two dimensional space of diagrams might seem restrictive, scientific diagrams can depict many more than two elements, can be used to visualize the same materials in myriad different ways, and can be constructed in a considerable variety of forms. This article takes up two generic puzzles about 2D visualizations. First, How do scientists in different communities use 2D spaces to depict materials that are not fundamentally spatial? This prompts the distinction between diagrams that operate in different kinds of spaces: real, ideal, and artificial. And second, How do diagrams, in these different usages of 2D space, support various kinds of visual reasoning that cross over between inductive and deductive? The argument links the representational form and content of a diagram (its vocabulary and grammar) with the kinds of inferential and manipulative reasoning that are afforded, and constrained, by scientists’ different usages of 2D space.

PurposeDisclosure research has argued that visuals are increasingly used in annual reports as a way to increase readability of the annual report, but comparatively little is known about of diagrams compared to graphs and photographs. The purpose of this paper is to provide a historical account of visuals use in corporate disclosure, with an emphasis on diagrams, to show changes from the 1940s until present-day reporting.Design/methodology/approachVisual research methods were applied to analyze how diagrams, photographs and graphs were used in 69 annual reports of the Swedish telecom company Ericsson.FindingsPhotographs have been used with increasing frequency since the 1950s. Graph and diagram use has increased significantly since the 1990s while photograph use remained stable, suggesting that graphs and diagrams increasingly complement photographs for visually representing the organization in corporate disclosure. Factors explaining the case company’s development include both internal (performance, individual preferences, shifting from a manufacturing-based strategy to a service-based strategy) and external (legislation, transformation of the telecom industry).Originality/valueVisual elements in annual reports are increasingly oriented toward immaterial representations of the organization’s standings and identity and diagrams are increasingly used and contribute to this. This finding motivates further research about diagram use in corporate communication, such as how different diagram types convey accounting messages, and whether diagrams serve as impression management devices. For regulators, it will be important to follow the emerging trend of diagram use, since it is becoming part of reporting practice.

This article reflects on the power and dangers of diagrams as a mode of anthropological exposition, comparing this particular form of non-text to the brief dalliance of mid-century anthropology with algebraic and logical formulae. It has been claimed that diagrams, like formulae, are clearer, simpler, or less deceptive than textual argument. By contrast, this article argues that diagrams are just as slippery and tricky as words, but that images and words slip and slide in different ways. Holding both diagrams and words together when building an argument enables not only a specific kind of rigor, but also moments of unexpected theoretical invention. This technique of holding together contrasting heuristics scales up as a productive epistemic device for anthropology more broadly.

Full textAbstract:
The analysis of spatio-temporal events, and especially of relationships between their different dimensions (space-time-thematic attributes), can be done with geovisualization interfaces. But few geovisualization tools integrate the cyclic dimension of spatio-temporal event series (natural events or social events). Time Coil and Time Wave diagrams represent both the linear time and the cyclic time. By introducing a cyclic temporal scale, these diagrams may highlight the cyclic characteristics of spatio-temporal events. However, the settable cyclic temporal scales are limited to usual durations like days or months. Because of that, these diagrams cannot be used to visualize cyclic events, which reappear with an unusual period, and don't allow to make a visual search of cyclic events. Also, they don't give the possibility to identify the relationships between the cyclic behavior of the events and their spatial features, and more especially to identify localised cyclic events. The lack of possibilities to represent the cyclic time, outside of the temporal diagram of multi-view geovisualization interfaces, limits the analysis of relationships between the cyclic reappearance of events and their other dimensions. In this paper, we propose a method and a geovisualization tool, based on the extension of Time Coil and Time Wave, to provide a visual search of cyclic events, by allowing to set any possible duration to the diagram's cyclic temporal scale. We also propose a symbology approach to push the representation of the cyclic time into the map, in order to improve the analysis of relationships between space and the cyclic behavior of events.

Full textAbstract:
In this paper, recent progress in graphic statics is combined with Williot displacement diagrams to create a graphical description of both statics and kinematics for two- and three-dimensional pin-jointed trusses. We begin with reciprocal form and force diagrams. The force diagram is dissected into its component cells which are then translated relative to each other. This defines a displacement diagram which is topologically equivalent to the form diagram (the structure). The various contributions to the overall Virtual Work appear as parallelograms (for two-dimensional trusses) or parallelopipeds (for three-dimensional trusses) that separate the force and the displacement pieces. Structural mechanisms can be identified by translating the force cells such that their shared faces slide across each other without separating. Elastic solutions can be obtained by choosing parallelograms or parallelopipeds of the appropriate aspect ratio. Finally, a new type of ‘elastographic’ diagram—termed a deformed Maxwell–Williot diagram (two-dimensional) or a deformed Rankine–Williot diagram (three-dimensional)—is presented which combines the deflected structure with the forces carried by its members.

Full textAbstract:
Linear diagrams have been shown to compare favourably to better known forms of set visualization, such as Venn and Euler diagrams, in supporting non-interactive assessment of set relationships. Recent studies that compared several variants of linear diagrams have demonstrated that users perform best at tasks involving identification of intersections, disjointness and subsets when using a horizontally drawn linear diagram with thin lines representing sets and employing vertical lines as guide lines. The essential visual task the user needs to perform in order to interpret this kind of diagram is vertical alignment of parallel lines and detection of overlaps. Space-filling mosaic diagrams which support this same visual task have been used in other applications, such as the visualization of schedules of activities, where they have been shown to be superior to linear Gantt charts. In this article, we present an experimental comparison of linear and mosaic diagrams for visualization of set relationships, in terms of accuracy, time-to-answer and subjective ratings of perceived task difficulty. The findings show that the two visualizations are largely similar with respect to these measures, suggesting that the choice of one or the other may be solely guided by other visual design considerations. Mosaic diagrams might be more suitable, for instance, in cases where miniature diagrams representing overviews of relations in different collections of sets are required, such as in small-multiples displays.

Full textAbstract:
Background: In this paper we report on the views of students with and without visual impairments on the use of illustrations, diagrams and drawings (IDD) in science lessons. Method: Our findings are based on data gathered through a brief questionnaire completed by a convenience sample of students prior to trialling new resource material. The questionnaire sought to understand the students’ views about using IDD in science lessons. The classes involved in the study included one class from a primary school, five classes from a secondary school and one class from a school for visually impaired students. Results: Approximately 20% of the participants thought that the diagrams were boring and just under half (48%) of the total sample (regardless of whether they were sighted or visually impaired) did not think diagrams were easy to use. Only 14% of the participants felt that repeated encounters with the same diagrams made the diagrams easy to understand. Unlike sighted students who can ‘flit’ across diagrams, a visually impaired student may only see or touch a small part of the diagram at a time so for them ‘fliting’ could result in loss of orientation with the diagram. Conclusions: Treating sighted and visually impaired pupils equally is different to treating them identically. Sighted students incidentally learn how to interpret visual information from a young age. Students who acquire sight loss need to learn the different rules associated with reading tactile diagrams, or large print and those who are congenitally blind do not have visual memories to rely upon.

Scholars have thoroughly discussed the visual aspects of Foucault’s archaeological and genealogical methods, as well as his own emphasis on how sight functions and what contexts and conditions shape how we see and what we can see. Yet while some of the images and visual devices he uses are frequently discussed, like Las Meninas and the panopticon, his diagrams in The Order of Things have received little attention. Why does Foucault diagram historical ways of thinking? What are we supposed to see and understand through these diagrams? To examine the role of the diagram in Foucault’s archaeological method, this paper provides a close reading of how the classical quadrilateral visualizes the structure, function, content, principles, and underlying assumptions of language and thought. In analyzing the diagram as a way for visualizing history, this paper demonstrates how Foucault enacts a new visual language that emphasizes the contingency of thought.

Full textAbstract:
Discrimination diagrams can be used to distinguish different tectonic settings of igneous rocks. To improve the quality and efficiency of the design of discrimination diagrams, an automatic design and assessment method for discrimination diagrams is proposed based on topology theory. The method is aimed at programming the traditional process of discrimination diagram design, enabling computers to simulate the visual discrimination process. It thus automatically designs tectonic setting discrimination diagrams by investigating all possible combinations of geochemical elements. In the experiment, analyses of 3803 gabbro samples were collected from three tectonic settings, including island arc, ocean island, and mid-oceanic ridge. Using the proposed method, we found thousands of discrimination diagrams with fields overlapping less than 10%. By analyzing these diagrams, the most critical elements (or element ratio pairs) are identified. Based on the result, the feasibility of using gabbroic rocks to discriminate between tectonic settings is illustrated and four representative discrimination diagrams, including the La/Y–Nb/Ba diagram, Nb/Sc–Sc/Ba diagram, Ba/Nb–Ba/Sc diagram, and La/Na2O–Nb/Ba diagram, are recommended for use. This research supports the view that gabbroic rocks can also be used to discriminate between different tectonic settings. The method could also be applied to other rock types.

Full textAbstract:
Abstract A notable feature of spoken Mandarin by many non-tonal language learners of Mandarin is incorrect or inaccurate tones. This contributes to significant impediments to effective communication by creating confusion, due to the fact that tones in Mandarin serve a lexical purpose. The problem is exacerbated by the relatively small number of Mandarin syllables. Traditionally, tones are taught by the classical aural process of “listen and repeat” in the classroom with the help of a language instructor and supplemented by out-of-classroom practice using model audio recordings. Both modes require learners to aurally detect the differences between tones and to imitate what they hear. With the wide availability of personal computers, computer-aided tone acquisition is an alternative to the “listen and repeat” method. The aim is to display and correlate the phonetic counterpart of tones, namely their pitch-time diagrams (also known as Fo diagrams). This provides visual feedback to guide learners to produce the correct tones through imitation of the correct pitch-time diagrams. While the pitch range of the Mandarin tones is well defined by Chao’s 5-level tone value scale for the four full tones, their corresponding pitch-time diagrams are not exactly the same as Chao’s tone diagrams. With disyllabic and trisyllabic Mandarin words, the pitch-time diagrams of the constituent syllables deviates even more from their tone diagram counterparts due to various coarticulation effects. This paper reports on a quantitative study of the tone values of single syllable, disyllabic and trisyllabic Mandarin words extracted from their pitch-time diagrams. The understanding of the results based on previous phonological studies is also provided. The results point to the effectiveness of pitch-time diagrams as a visual feedback tool for tone acquisition.

The theory of gas kinetics material studies objects that are abstract in nature. Therefore, its learning requires visual representations capable of visualizing these abstract objects, one of which is diagrams. The presence of diagrams in high school physics textbooks is considered important to aid the learning process. This research aims to determine the distribution of diagram categories, trends in diagram usage, and teachers’ perceptions of diagram usage in the Theory of Gas Kinetics material in high school physics textbooks with a descriptive quantitative research design. The research results show the distribution of diagram categories with the highest percentage in each analyzed book being the glossary image category, accounting for an overall percentage of 45%. The usage trends of each diagram category tend to fluctuate from year to year. Based on the findings of this research, teachers’ perceptions of diagram usage in the Theory of Gas Kinetics material have three main themes: diagrams are important as learning aids to make lessons more interesting and to represent the identity of science, especially physics; the use of diagrams depends on teachers’ needs; and diagrams help students understand the text and present physics concepts more specifically.

Este artículo se centra en las posibilidades que ofrecen los materiales hápticos y tridimensionales en los diagramas arquitectónicos creados en el proceso de diseño. Estos materiales pueden inspirar a los diseñadores y potenciar su creatividad. Los diagramas hápticos incorporan la experiencia del diseñador al problema de diseño y, por tanto, mejoran sus procesos mediante la eficacia incorporada. La primera sección del artículo enumera y explica brevemente los diagramas arquitectónicos y sus tipos. En la segunda sección se valoran los diagramas arquitectónicos analógicos o digitales con cualidades táctiles. Los diagramas hápticos se clasifican en función de su contenido y del entorno en el que se crean, con tres tipos de agudeza visual: si son lineales o fragmentarios, complejos o transparentes, y si están distorsionados geométricamente. El artículo sostiene que los diagramas arquitectónicos hápticos pueden mejorar la plasmación del pensamiento de diseño en la arquitectura. Los diagramas hápticos, ya sean analógicos, digitales o tridimensionales, pueden ayudar a los arquitectos a comunicarse y colaborar más eficazmente con las personas que perciben la arquitectura, al proporcionar una representación tangible y háptica del diseño. Y es que los diagramas hápticos son objetos que transmiten la materialidad de la forma y encarnan el conocimiento, transmitiendo la metodología del diseño de forma experiencial. AbstractThis article focuses on the possibilities afforded by haptic and three-dimensional materials in architectural diagrams created in the design process. These materials can inspire designers and enhance their creativity. Haptic diagrams incorporate the designer’s experience into the design problem, and therefore improve design processes through embodied efficiency. The first section of the article enumerates and briefly explains architectural diagrams and their types. In the second section, analog or digitally made architectural diagrams with tactile qualities are appraised. Haptic diagrams are classified based on their content and the setting in which they are created, with three types of visual acuity, including whether they are linear or fragmentary, complex or transparent, and whether they are geometrically distorted. The article argues that haptic architectural diagrams can improve the embodiment of design thinking in architecture. Haptic diagrams, whether analog, digital, or 3D, can help architects to communicate and collaborate more effectively with people perceiving architecture, by providing a tangible, haptic representation of design. This is because haptic diagrams are objects which convey materiality of form and embody knowledge, conveying design methodology experientially.

For reasons of clarity, a typical node–link diagram statically displayed on paper or a computer screen contains fewer than 30 nodes. However, many problems would benefit if far more complex information could be diagrammed. Following Munzner et al., we suggest that with interactive diagrams this may be possible. We describe an interactive technique whereby a subset of a larger network diagram is highlighted by being set into oscillatory motion when a node is selected with a mouse. The subset is determined by a breadth first search of the underlying graph starting from the selected node. This technique is designed to support visual queries on moderately large node-link diagrams containing up to a few thousand nodes. An experimental evaluation was carried out with networks having 32, 100, 320, 1000, and 3200 nodes respectively, and with four highlighting techniques: static highlighting, motion highlighting, static+ motion highlighting, and none. The results show that the interactive highlighting methods support rapid visual queries of nodes in close topological proximity to one another, even for the largest diagrams tested. Without highlighting, error rates were high even for the smallest network that was evaluated. Motion highlighting and static highlighting were equally effective. A second experiment was carried out to evaluate methods for showing two subsets of a larger network simultaneously in such a way that both are clearly distinct. The specific task was to determine if the two subsets had nodes in common. The results showed that this task could be performed rapidly and with few errors if one subset was highlighted using motion and the other was highlighted using a static technique. We discuss the implications for information visualization.

Reasoning with visual representations is an important component in solving many mathematical problems and in understanding many mathematical concepts and procedures. Students at all levels of mathematics frequently encounter visual representations—for example, diagrams, figures, and graphs—in discussions of mathematical ideas, in mathematics textbooks, and on tests. Teachers often use visual representations in the classroom when they present a mathematical problem, explain a problem's solution, or illustrate a mathematical concept. Although they frequently encounter and use visual representations in the mathematics classroom, neither teachers nor students may explicitly recognize the power of reasoning with visual representations or the potential for misconceptions that can arise from their use.

Software engineering is a discipline utilizing Unified Modelling Language (UML) diagrams, which are accepted as a standard to depict object-oriented design models. UML diagrams make it easier to identify the requirements and scopes of systems and applications by providing visual models. In this manner, this study aims to systematically review the literature on UML diagram utilization in software engineering research. A comprehensive review was conducted over the last two decades, spanning from 2000 to 2019. Among several papers, 128 were selected and examined. The main findings showed that UML diagrams were mostly used for the purpose of design and modeling, and class diagrams were the most commonly used ones.

This study was conducted with the objective of finding the perceivable effect of figures and backgrounds on residential streetscapes and their connections in visual complexity. The visual complexity depends on the extent of information a viewer can observe from a visible area. The information includes a number of visual elements along the streetscapes and their diversity and interconnections. The aim of this research was to analyze the structural hierarchical visual complexity of the streetscapes, caused by varied spatial arrangement and numerous spatial connections of the perceivable visual elements. The visual elements of 60 residential streetscapes were classified into figures and backgrounds using human perception of 20 subjects. The identified figures and backgrounds were arranged in a taxonomic diagram representing their connections. These taxonomic diagrams reflect the structural hierarchical visual complexity. Finally, taxonomic entropy was applied to statistically analyze the structural hierarchical visual complexity. When the taxonomic diagram is vertically and horizontally lengthy and the arrangement of the elements of taxonomic diagram is irregular, the complexity increases depicting a large number of figures whose spatial connections impart a high visual complexity to the streetscapes.

Full textAbstract:
Offline hand-drawn diagram recognition is concerned with digitizing diagrams sketched on paper or whiteboard to enable further editing. Some existing models can identify the individual objects like arrows and symbols, but they become involved in the dilemma of being unable to understand a diagram’s structure. Such a shortage may be inconvenient to digitalization or reconstruction of a diagram from its hand-drawn version. Other methods can accomplish this goal, but they live on stroke temporary information and time-consuming post-processing, which somehow hinders the practicability of these methods. Recently, Convolutional Neural Networks (CNN) have been proved that they perform the state-of-the-art across many visual tasks. In this paper, we propose DrawnNet, a unified CNN-based keypoint-based detector, for recognizing individual symbols and understanding the structure of offline hand-drawn diagrams. DrawnNet is designed upon CornerNet with extensions of two novel keypoint pooling modules which serve to extract and aggregate geometric characteristics existing in polygonal contours such as rectangle, square, and diamond within hand-drawn diagrams, and an arrow orientation prediction branch which aims to predict which direction an arrow points to through predicting arrow keypoints. We conducted wide experiments on public diagram benchmarks to evaluate our proposed method. Results show that DrawnNet achieves 2.4%, 2.3%, and 1.7% recognition rate improvements compared with the state-of-the-art methods across benchmarks of FC-A, FC-B, and FA, respectively, outperforming existing diagram recognition systems on each metric. Ablation study reveals that our proposed method can effectively enable hand-drawn diagram recognition.

College biology courses commonly use diagrams to convey information. These visual representations are embedded in course materials with the expectation that students can comprehend and learn from them. Educational research, however, suggests that many students have difficulty understanding diagrams and the conventions (e.g., labels, arrows) they contain. The present study evaluates biology students’ ability to comprehend scientific diagrams and the diagram characteristics that affect this comprehension. Participants were students in a physiology course who completed a multiple-choice test of diagram comprehension ability (DCA) (Cromley JG, Perez TC, Fitzhugh SL, Newcombe NS, Wills TW, Tanaka JC. J Exp Educ 81: 511–537, 2013). We coded the conventions used in each test diagram and used these codes to capture the diagram characteristics of conventions and complexity. Descriptive analyses examine students’ ability to understand scientific diagrams and which diagram characteristics cause the most difficulty. We also compared groups with low and high DCA scores to evaluate how students at different levels of comprehension ability are affected by diagram characteristics. Results show relatively poor DCA; the average total test score was only 69.5%. The conventions used in a diagram also affected diagram comprehension, and results show students had the most difficulty comprehending diagrams using a letter or numbering system, where arbitrary letters/numbers were used to signify objects and diagrams using cut-outs that showed cross sections and magnified interior views. Additionally, students’ comprehension was higher on diagrams with higher complexity (i.e., more types of conventions used), potentially indicating students are able to take advantage of the supports that different conventions provide. Implications for instruction are identified.

AbstractIn this article I present and discuss some criteria to provide a diagrammatic classification. Such a classification is of use for exploring in detail the domain of diagrammatic reasoning. Diagrams can be classified in terms of the use we make of them—staticordynamic—and of the correspondence between their space and the space of the data they are intended to represent. The investigation is not guided by the opposition visual vs. non-visual, but by the idea that there is a continuous interaction between diagrams and language. Diagrammatic reasoning is characterized by a duality, since it refers both to an object, the diagram, having its spatial characteristics, and to a subject, the user, who interprets them. A particular place in the classification is occupied byconstructional diagrams, which exhibit for the user instructions for the application of some procedures.

Visual representations, such as pedigree diagrams, are commonly used in genetics instruction, and they help students quickly visualize the phenotypes of multiple generations. In Study 1, we examined whether presenting a pedigree diagram of a wolf’s eye color in a rich and realistic manner (i.e., with rich perceptual images that resemble real animals) or in an abstract manner (i.e., with circles and squares representing animals) would help undergraduates learn from a brief, online lesson on inheritance of the wolf’s eye color, and whether they would transfer what they learned when reasoning about eye color in other species (near transfer) and other traits in other species (mid- and far transfer). Counter to our hypothesis, students transferred more with the rich diagram. In Study 2, we compared the rich diagram from Study 1 to a perceptually bland diagram (i.e., with color and textural features removed). There were no differences in students’ learning or transfer between the diagrams. These results suggest that realistic elements that are attention grabbing and easily interpretable by students can be beneficial for transfer in online lessons.

AbstractDuring the Late Antiquity and the Early Middle Ages, different strategies of visualizing music were adopted. In this article the history and the development of music-related diagrams is put into the larger context of a cultural history of visualization. The philosophical discussion on notational iconicity and diagrammatology, known as ‘Schriftbildlichkeit’, supplies a theoretical background for the description of the music diagrams offered here. The basic question is how visuality and musical graphic (diagrams and notation) interact focusing on a specific visual logic related to musical issues. After a short introduction to Sybille Krämer‘s concept of diagram and after working out some main characteristic of medieval diagrams, a selection of music related diagrams is depicted. The sources presented range from ancient Greek and Latin descriptions of musical diagrams (Aristoxenus of Tarentum, Phaenias of Eresus, Bakchios and Vitruvius) to the wing diagrams of Aristides Quintilianus and Martianus Capella, the structural graphics by Boethius and concludes with the notational diagrams in the Carolingian music treatises (Musica and Scolica Enchiriadis).

Diagram object detection is the key basis of practical applications such as textbook question answering. Because the diagram mainly consists of simple lines and color blocks, its visual features are sparser than those of natural images. In addition, diagrams usually express diverse knowledge, in which there are many low-frequency object categories in diagrams. These lead to the fact that traditional data-driven detection model is not suitable for diagrams. In this work, we propose a gestalt-perception transformer model for diagram object detection, which is based on an encoder-decoder architecture. Gestalt perception contains a series of laws to explain human perception, that the human visual system tends to perceive patches in an image that are similar, close or connected without abrupt directional changes as a perceptual whole object. Inspired by these thoughts, we build a gestalt-perception graph in transformer encoder, which is composed of diagram patches as nodes and the relationships between patches as edges. This graph aims to group these patches into objects via laws of similarity, proximity, and smoothness implied in these edges, so that the meaningful objects can be effectively detected. The experimental results demonstrate that the proposed GPTR achieves the best results in the diagram object detection task. Our model also obtains comparable results over the competitors in natural image object detection.

AbstractBiologists depend on visual representations, and their use of diagrams has drawn the attention of philosophers, historians, and sociologists interested in understanding how these images are involved in biological reasoning. These studies, however, proceed from identification of diagrams on the basis of their spare visual appearance, and do not draw on a foundational theory of the nature of diagrams as representations. This approach has limited the extent to which we understand how these diagrams are involved in biological reasoning. In this paper, I characterize three different kinds of figures among those previously identified as diagrams. The features that make these figures distinctive as representational types, furthermore, illuminate the ways in which they are involved in biological reasoning.

Category Theory has been applied in a series of papers by Ehresmann and Vanbremeersch (e.g., Bull. Math. Biol. 49(1): 13-50, 1987; SAMS 26: 81-117, 1997) to model complex systems such as biosystems, neural systems or social systems. For instance, in the category modelling a neural system, the internal representation of a physical object is described as the colimit of a diagram of receptors in the visual areas it activates. But there are several situations in which it would be useful to have a 'localized' notion of a colimit, for instance, to model the way an ambiguous object (which has two alternative readings) is memorized. The locally free diagrams and locally colimit diagrams, introduced by Guitart and Lair (Diagrammes 4: GL1-GL106,1980), could be used, but they are often too large and, anyway, are not uniquely determined. Particular locally free diagrams are introduced here, using the notion of the root of a category, which characterizes a minimal (in a precise sense) weakly coreflective subcategory.

As a distinct mode of mathematical representation and communication, geometry diagrams are both signs that represent abstract geometric concepts and visual images that offer graphical-spatial properties. Dynamic geometry environment offers a wide range of tools for its users to create and interact with geometry diagrams. In this paper, I propose a framework to characterize geometry diagrams that learners create in DGEs. The framework considers a learner’s approach to creating a geometry diagram (i.e., perceptualbased, measurement-based, construction-based, and transformation-based), the driving force that guides the learner’s specific actions in a DGE (i.e., tool-driven, and property-driven), and the constraints in the resulting diagram (i.e., drawing, underconstrained, overconstrained, and appropriately constrained). Examples of student work on two geometry construction problems are used to illustrate the use of the framework. These examples show that the proposed framework provides a useful tool to characterize geometry diagrams in DGEs.

The merits of visual images in conveying truths about the social world is widely recognized in social science, but some commentators have suggested the possible inadequacies of postwar economics on that score. Unimpressed by the omnipresence of diagrams in economics, they note that these are not images in the sense that maps are. The story of Boulding, an admirer of maps and strong believer in visual reasoning, who moved away from economics to become a general social scientist in the late 1940s, seems to confirm the above assessment. Yet, the difference between economists and other social scientists does not so much reside in the absence of images in economics—some diagrams in economics are maps—as in their declining role in postwar economic modeling. In that respect, the story of Boulding, his lack of influence on economics and his increased recognition among other social sciences testify to the gradual backsliding of visual imagination in postwar economics. If many today recognize the usefulness of diagrams for the dissemination of economic knowledge, only a few are aware that preceding the attempts to make these diagrams intelligible to their users, a real effort of visual imagination was required for their creators to ensure their explanatory power.

SummaryMany software tools provide facilities for depicting reaction network diagrams in a visual form. Two aspects of such a visual diagram can be distinguished: the layout (i.e.: the positioning and connections) of the elements in the diagram, and the graphical form of the elements (for example, the glyphs used for symbols, the properties of the lines connecting them, and so on). For software tools that also read and write models in SBML (Systems Biology Markup Language) format, a common need is to store the network diagram together with the SBML representation of the model. This in turn raises the question of how to encode the layout and the rendering of these diagrams. The SBML Level 3 Version 1 Core specification does not provide a mechanism for explicitly encoding diagrams, but it does provide a mechanism for SBML packages to extend the Core specification and add additional syntactical constructs. The Layout package for SBML Level 3 adds the necessary features to SBML so that diagram layouts can be encoded in SBML files, and a companion package called SBML Rendering specifies how the graphical rendering of elements can be encoded.The SBML Layout package is based on the principle that reaction network diagrams should be described as representations of entities such as species and reactions (with direct links to the underlying SBML elements), and not as arbitrary drawings or graphs; for this reason, existing languages for the description of vector drawings (such as SVG) or general graphs (such as GraphML) cannot be used.

This paper is a study of the visual characteristics of the medieval manuscript diagrams found in Theodosios’ Spherics. It provides a new taxonomy of eight types of diagrams found in the manuscript sources, and examines the way in which geometric information is encoded in the manuscript diagrams using a number of visual encodings. It then argues that these diagrams can be used to address ongoing research debates about whether the striking visual characteristics of medieval diagrams in mathematical texts are the result of deliberate choices by the premodern authors, the result of accidents of transmission, or both. Along the way, the paper identifies a further type of transmission error that is prevalent in the medieval transmission of mathematical diagrams.

Geometry diagrams use the visual features of specific drawn objects to convey meaning about generic mathematical entities. We examine the semiotic structure of these visual features in two parts. One, we conduct a semiotic inquiry to conceptualize geometry diagrams as mathematical texts that comprise choices from different semiotic systems. Two, we use the semiotic catalog that results from this inquiry to analyze 2,300 diagrams from 22 high school geometry textbooks in which the dates of publication span the 20th century. In the first part of the article, we identify axes along which the features of geometry diagrams can vary, and in the second part of the article, we show the viability of using the semiotic framework to conduct empirical studies of diagrams in geometry textbooks.

Full textAbstract:
UML (Unified Modeling Language) diagrams are graphical representations used in software engineering which play a vital role in the design and development of software systems and various engineering processes. Large, good-quality datasets containing UML diagrams are essential for different areas in the industry, research, and teaching purposes; however, few exist in the literature and it is common to find duplicate elements in the existing datasets. This might affect the evaluation of the models obtained when using these datasets. This paper addresses the challenge of creating a ground truth dataset of UML diagrams, including semi-automated inspection to remove duplicates and ensuring the correct labeling of all UML diagrams contained in the dataset. In particular, a dataset of six UML diagram classes was assembled, comprising a total of 2626 images (426 activity diagrams, 636 class diagrams, 352 component diagrams, 357 deployment diagrams, 435 sequence diagrams, and 420 use case diagrams). Importantly, unlike other existing datasets, ours contains no duplicate elements and all diagrams are correctly labeled. Our curated dataset is a valuable and unique resource for the research community, serving as a foundation for training and evaluating diverse artificial intelligence models. In this paper, we demonstrate this by training and testing several deep learning models using our dataset, achieving highly satisfactory results compared to those presented in other works in the literature. Additionally, our experimental results highlight the potential of visual transformers for UML diagram classification, setting our approach apart from others that predominantly used convolutional neural networks for similar tasks.

Models play an important role in systems analysis and design (SAD). A diagrammatic model is defined as a mapping from a domain to a visual representation in such a way that relevant information is preserved to meet a specific goal. So far, cognitive research on diagram criteria in relation to task performance has been fragmented. The aim of this paper is to (1) consolidate research on the cognitive processing steps involved during understanding and task performance with diagrams, (2) consolidate corresponding criteria for such diagrams to best support cognitive processing, and (3) demonstrate the support effective diagrams provide for performing SAD tasks. Addressing the first aim, we develop a theoretical cognitive framework of task performance with diagrams called CogniDia. It integrates different cognitive theories from research on diagrams in software engineering and information systems. Regarding the second aim, we review the literature to organize criteria for effective cognitive processing of diagrams. We identify research gaps on verbal and task processing. Regarding the third aim, we use the theoretical cognitive framework to investigate how diagrams support the SAD process effectively.

In learning biology, teachers often use visual media, such as diagrams, to help students understand the concept. This study was focused on how students’ mental representation (MR) when they read biological diagrams, either representation convention diagram or spatial isomorphism diagram. The student’s MR was analyzed using a worksheet modified from an MR measurement model of CNET protocol. This model involves three main components of the MR’s working memory: causal network, probability parameter, and utility parameter. Ninety 11th grade students of a senior high school in Bandung voluntarily involved in this study. Only 59 students, however, performed the worksheet completely. The result revealed that each student gave a different pattern of MR either when he/she read convention or spatial diagram. These differences could be traced since the student decides and orders the information elements and makes a causal network. Based on this result, we suggest that this method of MR analysis using a worksheet can be used to understand how student’s working memory works on MR building when they read a diagram. Understanding how the student can construct MR is a necessary platform to provide appropriate visual media that will help the student improve their learning achievement.

<p><strong>Abstract.</strong> The goal of this research is to apply diagrams to environmental color studies. The experience of environmental color is not only visual experience, but also the relationship of the color and the form of the object, the material, the place, the human perception experience. Diagrams records these factors along with the human perception experiences. These diagrams make it possible to study and analyze environmental color more deeply and more easily. In this paper, we first reviewed the "case studies of environmental color workshops" and "theory of information processing by rearranging matrix of Jacques Bertin" which are related to this research. Next, we conducted an environmental color workshop and evaluated the application of diagrams at workshop by students and experts (design teachers and designers). As a result, we confirmed that the diagrams proposed by us are effective for the environmental color workshop. In particular, it was confirmed that these diagrams are effective for group discussion (analysis).</p><p>The workshop was held at the South China University of Technology (Guangzhou, China) on October 14 – October 17, 2016 (Figure.1). The participants were 5 students. First, students walked along a path near the natural lake in the campus and recorded the observed color objects and their perception experiences. Next, the students (A, B, C, D, E) entered the observation results into the matrix type diagram (a) (Figure.2). In diagram (a), the colors observed by each student were displayed on the left side of the observation route, and the photographs of the color objects, the perception experiences on the color objects, and the landscape photographs of the observation place were arranged on the right side of the observation route. Next, according to Jacques Bertin's theory (visual variables and rearrangement of the matrix), diagram (a) was transformed into diagram (b) (Figure.3) and group discussion and information analysis were carried out. In diagram (b), color objects are represented as "rows", and various attributes of color objects as "columns". The attributes of color objects are the keywords extracted from the "perception experiences for color objects" in diagram (a). In the notation of visual variables, ordinary impression was displayed as gray dot, good impression was displayed as orange dot, bad impression was indicated as blue dot, and the number of observers was indicated by the size of the dot. Looking at Figure.3-left, the most common thing is finding color objects by "brightness", and the number of observers who recorded the "brightness" of bicycle is the largest. By rearranging the matrix in diagram (b), we found that the color objects can be divided into "gray", "white" and "yellow" (Figure.3-middle), there were many good impressions for "yellow and white (flowers)", and there were many bad impressions for "gray and white (street lights)" (Figure.3-right).</p>

Architecture diagrams are required tools for software development, system design, and communication. They facilitate the understanding of complex systems by providing a visual representation of components, relationships, and data flow. However, creating and interpreting these diagrams can be time-consuming and require significant expertise. Generative Artificial Intelligence (AI) offers a potential solution to automate the creation process and improve comprehension. This paper explores how generative AI can be leveraged to automatically generate diverse architectural diagrams from textual descriptions and code repositories. Additionally, the research investigates how AI techniques can assist in understanding and analyzing existing diagrams, thereby easing maintenance, documentation, and stakeholder communication. This paper discusses existing approaches, emerging techniques, challenges, and future directions in this evolving field. Our findings indicate that generative AI can significantly reduce effort in diagram creation and improve analysis while also exploring the limitations of current models.

In nine naïve subjects eye movements were recorded while subjects viewed and visualized four irregularly-checkered diagrams. Scanpaths, defined as repetitive sequences of fixations and saccades were found during visual imagery and viewing. Positions of fixations were distributed according to the spatial arrangement of subfeatures in the diagrams. For a particular imagined diagrammatic picture, eye movements were closely correlated with the eye movements recorded while viewing the same picture. Thus eye movements during imagery are not random but reflect the content of the visualized scene. The question is discussed whether scanpath eye movements play a significant functional role in the process of visual imagery.

System modeling language (SysML) diagrams generated manually by system modelers can sometimes be prone to errors, which are time-consuming and introduce subjectivity. Natural language processing (NLP) techniques and tools to create SysML diagrams can aid in improving software and systems design processes. Though NLP effectively extracts and analyzes raw text data, such as text-based requirement documents, to assist in design specification, natural language, inherent complexity, and variability pose challenges in accurately interpreting the data. In this paper, we explore the integration of NLP with SysML to automate the generation of system models from input textual requirements. We propose a model generation framework leveraging Python and the spaCy NLP library to process text input and generate class/block definition diagrams using PlantUML for visual representation. The intent of this framework is to aid in reducing the manual effort in creating SysML v1.6 diagrams—class/block definition diagrams in this case. We evaluate the effectiveness of the framework using precision and recall measures. The contribution of this paper to the systems modeling domain is two-fold. First, a review and analysis of natural language processing techniques for the automated generation of SysML diagrams are provided. Second, a framework to automatically extract textual relationships tailored for generating a class diagram/block diagram that contains the classes/blocks, their relationships, methods, and attributes is presented.

One of the most effective ways to improve the training process is to use data visualisation. Visualisation is understood as a set of methods for presenting numerical information or physical processes in a form convenient for visual perception and analytical comprehension. This approach allows you to create visual graphic images that reflect the substantive characteristics of the phenomena under study, and at the same time allows you to compactly present large amounts of data, facilitating their analysis, interpretation and use in decision-making. Purpose: to substantiate the feasibility of using statistical diagrams for visualization and graphical representation of statistical data using the example of sports games. Material and methods: The article used theoretical research methods, namely analysis, synthesis and generalization of data from scientific and scientific-methodical literary sources; content analysis of publicly available Internet resources; synthesis of the obtained scientific information; comparative analysis. Results: the means of visualization and graphical display of statistical indicators in sports games were developed and generalized, which significantly contributes to better perception and understanding of information. Conclusions: the feasibility of using visualization and graphical display of statistical data in sports games was proven in view of methodological and didactic considerations. It has been established that the most common types of statistical diagrams used in such studies are random variable distribution diagrams, time interval diagrams, correlation diagrams, and comparative column and line diagrams. Thus, a key and integral stage of graphical support for data analysis is the justified choice of the appropriate type of statistical diagram.

Roundhouse diagram is a visual tool which helps to reveal what a student think about science topics and reflects information that students organise in their mind. The purpose of this study was to investigate the effect of using roundhouse diagrams on prospective classroom teachers’ understanding of ecosystem, food chain, energy flow and material cycles. The roundhouse diagram was used with the experimental group (n = 44), while a traditional teaching method was employed with the control group (n = 43). Environmental Achievement Test consisting of 25 questions was administered to the 87 preservice teachers as pretest and posttest. The results indicated that the use of roundhouse diagrams significantly improved prospective classroom teachers’ understanding of ecosystem, food chain, energy flow and material cycles. In the light of the obtained results, some practical implications are discussed. Key words: academic achievement, ecosystem, roundhouse diagram, science education.
