Sleep Apnea Detection Based on Dynamic Neural Networks

One of widespread breath disruption that takes place during sleep is apnea, during this anomaly people are not able to get enough oxygen. The article describes method for breathing analyses that is based on neural network that allows recognition of breath patterns and predicting anomalies that may occur. Class of machine learning algorithms includes lots of models, widespread feed forward networks are able to solve task of classification, but are not quite suitable for processing time-series data. The paper describes results of teaching and testing several types of dynamic or recurrent networks: NARX, Elman, distributed and focused time delay.

Network Society: Aggregate Topological Models

An innovative approach for analysis of “network society” with its large- scale and multicomponent features has been proposed. A new network model - a model of so-called aggregate networks has been developed as a key tool for such analysis. These aggregate structures topologically are not identical in their global and local scales, and thus distinguished from canonical large-scale networks. It was elicited that aggregate network entities have significant features in their topological vulnerability in comparison with canonical ones. This is crucial for building resilient constructions of the network society. Also some additional distinctions for the concepts of “network” and “graph” have been formulated.

Optimal Information Security Investment in Modern Social Networking

For further clarification of methodological issues of the social network’s information security we stratified the systems that support human relations into three components of different nature: computer, communication and social ones. A security model for a network component is developed using consideration of security for individual nodes . Modeling of attacks on networks in whole is analyzed taking into account specification of network security level. The results for real computer, communication and social entities supported that for a network attacked intentionally it is better off allocating the investment proportionally to degree centralities of the nodes rather than uniformely. The analysis further hints that to make investment justifiable to protect a network, its proprietor should spend lesser than to reach approximately 0.4 of network security level.

Designing the cumulative indicators and criteria for educational process subjects competence assessment

This article shows different kinds of cumulative indicators in various fields of knowledge are widely used for the object’s status or processes assessment. Its main purpose is to give a comprehensive assessment the selected object characteristics. Such indicators are easy to use and serve as a kind of sensors as their deviations from certain given values indicate changes in state of the object and its suggested further analysis. The indicator sensitivity to an object state changing at different levels of its hierarchy is directly connected with the choice of the object decomposition level on which the integral component constructed. Keywords—integral criteria, methods of artificial intelligence, information technology.

Optimal Protection of Networks in Social Media while Counteracting Disasters and Emergencies

BASIC PH model were put into practice using cognitive, emotional and creative supporting tools. The sessions culminated in the creation of a teamwork plan designed to preserve the program’s achievements. Results: The act of sharing difficulties within the support group generated cohesion and hope, which are components of resilience. The relationships within the group became more open, and the participants were more easily able to communicate their difficulties and felt more connected (also factor of resilience). The intervention provided the participants with a support framework, and enhanced their ability to cope with stressful situations. Conclusion: Organizational support based on a resiliency model can strengthen the individual’s ability to cope with daily stressful situations and enhance cohesion, that in turn may have a positive influence on the organization’s ability to handle changes and crisis.

Ontological simulation for educational process organisation in a higher educational institution

Following the new-generation standards is needed to form a task list connected with planning and organizing of an academic process, structure and content formation of degree programmes. Even when planning the structure and content of an academic process, one meets some problems concerning the necessity to assess the correlation between degree programmes and demands of educational and professional standards and to consider todays job-market and students demands. The paper presents examples of ontological simulations for solutions of organizing educational process problems in a higher educational institution and gives descriptions of model development. The article presents two examples: ontological simulation when planning an educational process in a higher educational institution and ontological simulation for describing competences of an IT-specialist. The paper sets a conclusion about ontology application perceptiveness for formalization of educational process organization in a higher educational institution.

Creating a Virtual Machine in Matlab as Part of Business Game for Educating People with Special Needs

The paper addresses the problem of adapting people with special needs to their future working environment. We support the idea that organizing courses and business cases on a virtual machine will be a solution to this problem. The analysis of people with special needs behavior in the actual learning process and their e-learning experience shows their ability to adjust their actions and develop adaptation skills relevant to any environment. Then, we analyze their behavior and the ways to involve them in the virtual setting activities, thus enabling them to feel that they are productive employees and members of the society. As the key evidence, we give an algorithm for creating a virtual business game that can engage people of any professions and social niches. We present the detailed algorithm of competences design and instruments of LSA- method, which helps to create a virtual machine for the decision-making process. Participants, including those with special needs, can also correct their decisions, which help them develop their abilities to adapt to their future working environment in a company. The work is interdisciplinary at the confluence of the disabled people behavior analysis and application of the key e-learning technologies. The main advantage of arranging such courses on the virtual machine is that people with special needs acquire the adaptation, communication, and decision-making skills as a part of distance learning.

Network platform of program governance for E-health service

Social networks and their tools compound sophisticated compositions. Recent studies investigated diverse withstanding aspects of these socio-cyber systems. However, some methodological issues of the international medical networks required further clarification. In this regard, we stratified the networks that support human relations into the layers of private sector, national, provincial, local governments, citizen society organizations and informal structures. A mechanism composing and modeling interactions of different organizations and social networks engaged in different phases of program governance processes in the areas of medical tourism services designed.

Visual language as a mean of communication in the field of information technology

There is a challenge of developing computer programming visual language in the sphere of interdisciplinary research - cybernetics and philosophy, in particular, philosophy of mathematics, philosophy of language and new area of the philosophical analysis - ≪philosophy of information≫. We consider the aspect ≪language - thinking≫ and the stages of developing interaction between a person and information environment by means of programs. We set up the problem concerning the necessity to find the ways of constructing software by nonprofessionals. We offer the efficient way to eliminate the distinction in the system ≪interface-software programming language≫ via using visual programming language as a tool for people to communicate with machine. We designate the prospects of using visual programming languages and difficulties in their creation and implementation. We conclude that developing cloud technologies opens up new opportunities to make cross-subject tools of creating and changing software functionality by people without professional qualifications in programming. It is noted that developing and using visual languages can have considerable impact on the development of nano-bio-info-cogno technologies (NBIC) as well as on the research in the field of cognitive management, artificial intelligence as modeling visual thinking and other research areas. We recommend further understanding how to use visual programming languages in social, philosophical and psychological aspects.

Multidimensional Data Visualization Methods Based on Generalized Graphic Images

The main peculiarity of decision-making systems is their growing mathematization. The reason for applying mathematical principles is usability of simple procedures capable of being performed on a computer. In addition, most of the tasks solved on computer are of algorithmic nature; require solution existence and consistent computational methods. Classical solution is unique and reliable in a finite amount of time via search methods.
