Research strategy for development of instrument and computer support for diagnosis and treatment of addictive patients considering the consequences of the covid-19 pandemic

The article states кesearch strategy for development of instrument and computer support for diagnosis and treatment of dependents of patients considering the consequences of the COVID-19 pandemic. Due to the growing worldwide number of addicted people and the deterioration of this situation due to the spread of the COVID-19 pandemic, it is important to introduce improved methods of computer diagnosis, treatment and follow-up of addicted patients and those suffering from on diseases of the central nervous system (CNS). These categories of patients make up a risk group. The proposed methods include the development of a computer database "Addictiveness", the accumulation and generalization of instrumental diagnostic data and the results of patients examinations of the development of a mathematical procedure for correlation "Brain Similarity", to identify signs of symptoms closeness of a dependent patient to one from the groups of already examined persons and those who underwent treatment. On the basis of mathematical methods "Procedure Brain Similarity" and the corresponding data of the database "Addictiveness" the creation of a software package of addicted patients precision diagnostics with computer calculations is provided. Scientific research results, relevant theoretical and experimental developments are the methodological basis for sufficiently qualified studies of a number of poorly studied human CNS phenomena, including not only diagnosis and treatment of addictive patients, but also understudied phenomena of extreme functions of cognitive brain activity

Computer support for the shape formation of helical surfaces with a disk tool

An analytical description of the process of making helical surfaces with a disk tool with a substantiated definition of the objective function is proposed. By analogy with coordinate metrology, it is proposed to adopt a minimum tolerance zone as an objective function. This allows to specify the required solution error and eliminates the need to use normal lines or tangents to the profiles. An example of calculating the profile of a helical groove of a twotoothed end mill, performed with an error of 0.05 mm is presented. Keywords: helical surface, disk tool, computer support, optimization, minimum tolerance. [email protected]

A Visualization Approach to Facilitate the Early Stages of Product Design

Diagramming languages are heavily used in design and system analysis. Different languages have varying impacts on the effectiveness of designers. The author believes that there is no appropriate diagramming tool that is of substantial benefit to designers, especially in the early, pre-geometry stages of product development. A new tool, design schematics (DS), is introduced to fulfill this need. The general benefits of diagramming are outlined and the potential of diagramming tools is explored. Advantages and disadvantages of some existing diagramming methods are discussed. Analysis of diagramming methods motivates the development of DS. DS is consistent with the generic design process developed by Salustri. Several interrelated examples demonstrate how DS can capture important information during design stages. A detailed example of a coffee maker is carried out. It is executed as if the author were actually designing a coffee maker. Interrelated diagrams of the design highlight how DS helps in designing during the early stages. Computer support for development and full exploitation of DS is needed. The author believes that DS can be of great benefit to practising engineers. While there is not yet any quantitative data by which DS can be evaluated, there is anecdotal evidence suggesting that the tool has potential to be of benefit in design areas.

Computer Support for Discussions in Spatial Planning

1. Introduction Spatial planning deals with the problem of distributing the limited resource "space" among different uses and users. It can be highly challenging to find a balanced land-use pattern, for example in urban agglomerations. Different interest groups such as residents, industry, and ecologists will claim different desirable land-uses for a given area. Spatial planning is also about locating unwanted land-use such as waste facilities. In this case, interest groups (e.g. city councils, neighbourhood organizations) and individuals will fight nearby locations. This situation is known as the NIMBY problem: “Not In My BackYard!” In democratic societies, decisions such as those in spatial planning are made by political representatives in cooperation with public administration and residents. The final decision will usually be based on a number of consecutive prior decisions, or choices, which are made by different groups of stakeholders. At any of these decision levels, there are two important methods to reach a conclusion: consensus finding, or voting. Both will be preceded by more or less intensive discussions and argumentation. The ultimate goal of discussions is to achieve sustainable development by integrating the objectives of diverse stakeholders. Thus, we argue that discussions are a crucial element of spatial planning procedures and are to be integrated with planning and decision support techniques. Discussions will have diverse formats in different planning projects. For example, the number of participants may vary from only two to hundreds and more; participants may get together or stay separated in space and/or time; discussion may be un-moderated, or moderated and structured. Nevertheless, discussion contributions (statements, messages, arguments, articles) in spatial planning will commonly contain a spatial reference. This does allow to link discussion support to spatially enabled decision support techniques as argued in this chapter. In section 2, we will review general theories on argumentation and introduce major concepts of computer-supported cooperative work. Next, geographically referenced discourse will be analysed in more detail leading to the argumentation map model (section 3). Section 4 develops use cases for GIS-based discussion support, and section 5 presents some existing applications. Finally, we will speculate about future developments in computer support for discussions in spatial planning (section 6).
