O uso da cor em diagramas na Engenharia de Software não é novidade, em especial na Linguagem Unificada de Modelagem (UML), que consiste em um conjunto de quinze diagramas utilizados para documentar e especificar a complexidade de um software. Porém, a aplicação da cor muitas vezes é feita de forma aleatória ficando a cargo da subjetividade do projetista ou dos softwares utilizados para o desenho destes diagramas. O presente artigo aborda o uso das cores no diagrama de classes da UML segundo o modelo proposto por Coad, Lefebvre e De Luca (1999), que aplica a cor a partir de uma prática profissi

Abstract:

Unified Modelling Language (UML) is currently accepted as a defacto standard language for modeling the software in the software industry. It will allow to implement object oriented concepts to model the software system. It provides a complete pictographic representation of software. Broadly these UML diagrams are classified into two groups viz. Structural diagrams and Behavioral diagrams. The sequence diagrams and Activity diagrams belongs to the second group i.e. behavioral diagrams. The sequence diagram represents the sequence of messages flowing from one object to another and activity diagr

Abstract:

The idea of the diagram as a ‘working object’ is used to discuss the biologist C. H. Waddington’s epigenetic landscape (EL) diagrams. This article investigates the diagrams’ history and discusses their usages in relation to Stengers’s idea of the ‘nomadic concept’. What is it about these diagrams that have made them a tool for transdisciplinary research? The article argues that it is useful to distinguish between the diagram and the illustration, and that it is in part because the EL diagrams retain an illustrative graphic character that they have been apt for imaginative adaptation and reuse.

Abstract:

We expand the earlier invented method of massive Feynman diagrams calculation, namely, the differential equations method, to N-point diagrams. We obtain a simple algorithm which allows us to reduce the vertex-type diagram to the propagator-type diagrams, the box-type diagram to the vertex-type diagrams and, in general, the N-point diagram to the (N-1)-point diagrams. We show that this method provides a simple procedure of evaluating the result without D-space integrals (for the dimensional regularization) calculation.

Abstract:

A virtual link diagram is called normal if the associated abstract link diagram is checkerboard colorable, and a virtual link is normal if it has a normal diagram as a representative. Normal virtual links have some properties similar to classical links. In this paper, we introduce a method of converting a virtual link diagram to a normal virtual link diagram. We show that the normal virtual link diagrams obtained by this method from two equivalent virtual link diagrams are equivalent. We relate this method to some invariants of virtual links.

The strain-based and stress-based workability diagrams are often used to predict the initiation of ductile fracture in metal forming.

It is shown in the present paper that under these conditions the strain-based workability diagram is identical to the stress-based workability diagram. Using an available stress-based workability diagram the strain-based workability diagram is found in a much larger domain in the space of two in-surface pri

The generation of test cases using a reference between the statechart diagram and the status diagram is still inadequate because in the case of the test produced there is no test data. The selection of test data for many test cases will be tedious and time consuming. In this paper, it is proposed to generate test data automatically based on e

Abstract:

Modeling methods in general and Unified Modeling Language (UML) in particular, have gained trust in software developer communities. UML diagrams are profoundly utilized by software developers to build, model and visualize the working of the software. While the comprehension of the UML models can introduce ambiguities in the software. As there is no specification on how these models should be analyzed. Therefore, these models sometimes convey inconsistent semantics in the software systems. So, there must be some automated procedure in which these models be transformed into one another, to remov

Abstract:

In this paper we introduce a representation of knots and links called a cube diagram. We show that a property of a cube diagram is a link invariant if and only if the property is invariant under five cube diagram moves. A knot homology is constructed from cube diagrams and shown to be equivalent to knot Floer homology.

Abstract:

Simulink is a well-known block diagram-based tool for modular design and multidomain simulation of Cyber-Physical Systems (CPS). However, the simulation by Simulink cannot completely cover the state space or behavior of a target system, which would not ensure the correctness of the developed block diagrams in Simulink. In this work, we present a contract-based method, which supports compositional reasoning and refinement, for proving the correctness of Simulink block diagrams with discrete-time and continuous-time dynamic behavior. We use the assume-guarantee contract as a specification langua

Abstract:

Addition is one of the timing critical operations in most of modern processing units. For decades, extensive research has been done devoted to designing higher speed and less complex adder architectures, and to developing advanced adder implementation technologies. Decision diagrams are a promising approach to the efficient many-bit adder design. Since traditional binary decision diagrams does not match perfectly with the task of modelling adder architectures, other types of diagram were proposed. If-decision diagrams provide a parallel many-bit adder model with the time complexity of Ο(log2n)

Abstract:

Absolute statistical data are very often expressed by a diagram in thematic maps. The ArcGIS 9 software from ESRI is commonly used for the production of cartographic output, but there are only a few possibilities for how to express data by diagram maps. A program extension called “Diagram map creator” was developed at the Department of Geoinformatics, Palacký University in 2010. This extension serves as a supplement for the automatic generation of various diagram maps. The program code, user interface and the possibilities of and the use of the “Diagram map creator” extension are presented in

Abstract:

Unified Modeling Language (UML) diagrams serve as essential tools for visualizing system structure and behavior in software design. With the emergence of Large Language Models (LLMs) that automate various phases of software development, there is growing interest in leveraging these models for UML diagram generation. This study presents a comprehensive empirical investigation into the effectiveness of GPT-4-turbo in generating four fundamental UML diagram types: Class, Deployment, Use Case, and Sequence diagrams. We developed a novel rule-based prompt-engineering framework that transforms domai

Abstract. In this paper a vector model of timing diagram of automatic machine is developed, which allows us to solve a variety dynamic tasks by changing the parameters of timing diagram of its mechanisms. The connection between the parameters of the timing diagram of automatic machine and equations of motion mechanisms through functions of position and transfer functions of mechanisms is established. The vector model of timing diagram can be used to optimize the timing diagrams of looms and polygraphic machines.

Abstract:

We consider codimension one gradient flows on closed surfaces with minimal number of singular points. There are two type of such flow: saddle-node (SN) and saddle connections (SC). We use the chord diagrams to specify flows up to topological trajectory equivivalence. A chord diagram with a marked arc is complete topological invariant of a SN-flow and a chord diagram with T-insert -- of SC-flow. We list all such diagrams for flows on norientable surfaces of genus at most 2 and nonorientable surfaces of genus at most 3. For each of diagram we found inverse one that correspond the inverse flow.

Abstract:

The warping degree of an oriented knot diagram is the minimal number of crossing changes which are required to obtain a monotone diagram from the diagram. The minimal warping degree of a knot is the minimal value of the warping degree for all oriented minimal diagrams of the knot. In this paper, all prime alternating knots with minimal warping degree two are determined.
