Visual methods of formalization of knowledge in the conditions of the synchronous technologies of system engineering

Visual environment of cognitive graphics for end-to-end engineering project-based education

“…Then the visual model can be described in XML, the elements of which are the concepts and judgments given in Figure 2. In general, the VI-XML fi le has the following structure [7]. The root element of knowledge contains one element of ideas and opinions, and they, respectively, contain any number of elements of idea or opinion.…”

“…For this purpose, a set of techniques (notations) of use of the graphical models (graphical notation) and techniques of formal textual description (textual notation), together with the means of interactive human-machine interaction, is created. This provides a visual and detailed presentation of the characteristics of objects in the design process, Figure 1: The relationship of the levels of visual modeling [7] expert analysis and online decision-making [12]. The visual design methods are based on visual languages and methods (rules -notations) of the model development based on them.…”

“…SMEs can play a vital role in assisting and fostering entrepreneurial activity with a special focus on information technology businesses [4]. A variety of effective approaches to knowledge transfer is implemented through a variety of visual tools and models [2][3][4][5][6][7][8][9]. Comprehensive training in engineering specialties is largely based on visual tools that ensure the creation, transmission,and application of mechanisms for the formalization and manipulation of knowledge in a single semantic interdisciplinary and interspecifi c hierarchy, providing a single and complete description of the product life cycle processes [10,11].…”

“…The postulate "one picture replaces 1000 words, and one diagram 1000 drawings"has already become classic. Among the levels of visual models of knowledge representation about production systems, fi rst of all, it is required to single out conceptually-abstract [6], structural-functional [7], and object models [8]. The research on the methods of synthesis of a set of valid, reproducible and systemic methods and means of visual description of the processes occurring in complex systems is relevant.…”

Using FIAT currencies to arbitrage on cryptocurrency exchanges

“…What is quite interesting is the fact that independent camps of researchers presenting quite the opposite approaches have been formed in the field of research on the efficiency of the market under study. Scientists belonging to the first of these groups are of the opinion that the cryptocurrency market meets the tenets of the efficient market hypothesis - Brauneis and Mestel (2018), Nadarajah and Chu (2017), Vlasov and Demin (2017), Tiwari (2018), Bariviera (2017), Sensoy (2018). However, researchers from the other group, most of whom have conducted their studies relatively recently, express the opposite view -for example, Cheah (2018) or Yonghong (2018).…”
