Software theory change for resilient near-complete specifications

Software evolution and its laws are essential for antifragile system design and development. In this paper we model early-stage perfective and corrective changes to software system architecture in terms of logical operations of expansion and safe contraction on a theory. As a result, we formulate an inference-based notion of property specification resilience for computational systems, intended as resistance to change. The individuated resilient core of a software system is used to characterize adaptability properties

JSClassFinder: A Tool to Detect Class-like Structures in JavaScript

With the increasing usage of JavaScript in web applications, there is a great demand to write JavaScript code that is reliable and maintainable. To achieve these goals, classes can be emulated in the current JavaScript standard version. In this paper, we propose a reengineering tool to identify such class-like structures and to create an object-oriented model based on JavaScript source code. The tool has a parser that loads the AST (Abstract Syntax Tree) of a JavaScript application to model its structure. It is also integrated with the Moose platform to provide powerful visualization, e.g., UML diagram and Distribution Maps, and well-known metric values for software analysis. We also provide some examples with real JavaScript applications to evaluate the tool.Comment: VI Brazilian Conference on Software: Theory and Practice (Tools Track), p. 1-8, 201

A Bootstrap Theory: the SEMAT Kernel Itself as Runnable Software

The SEMAT kernel is a thoroughly thought generic framework for Software Engineering system development in practice. But one should be able to test its characteristics by means of a no less generic theory matching the SEMAT kernel. This paper claims that such a matching theory is attainable and describes its main principles. The conceptual starting point is the robustness of the Kernel alphas to variations in the nature of the software system, viz. to software automation, distribution and self-evolution. From these and from observed Kernel properties follows the proposed bootstrap principle: a software system theory should itself be a runnable software. Thus, the kernel alphas can be viewed as a top-level ontology, indeed the Essence of Software Engineering. Among the interesting consequences of this bootstrap theory, the observable system characteristics can now be formally tested. For instance, one can check the system completeness, viz. that software system modules fulfill each one of the system requirements.Comment: 8 pages; 2 figures; Preprint of paper accepted for GTSE'2014 Workshop, within ICSE'2014 Conferenc

Electrical systems and networks

Designed to clarify the sequence of calculating the course project in the discipline "Electrical Systems and Networks" students of foreign education. The basic disciplines for successful mastering of the program material during the practical training are: algorithmization and software, theory of automatic control, distribution electrical networks. These guidelines provide for the formation of the following competencies: the ability to improve existing technological systems and find the best methods for their operation; ability to carry out research by methods of classical sciences, planning, organize and carry out scientific researches in the field of electric power, electrical engineering and electromechanics
