Successful operation of the railways as a large technological system is directly related to the reliable and timely transmission of data and information. Therefore, the role of the information and communication system (ICS) has irreplaceable importance for operation and functioning of the railways. Considering that the railway modernization represents an uninterrupted process, it is necessary to ensure constant technical and technological development and application of the latest achievements in the field of information and communication systems. The railway ICS, among other things, provides infrastructure for the automatic control systems, traffic management and control, monitoring and navigation systems, data processing devices, and it also provides support to other subsystems designed for safe and consistent use of the line, as well as efficient management of the modern rail transportation system.

Information And Communication

This paper focuses on the methods and the mechanisms of E-commerce and E-marketing, and the important role of international electronic companies in this vital and digital field. The spreaders of the digital economy and the techniques of information and communication technology are deployed with applications of E-commerce and E-marketing. Thus, the digital globalization opens the horizon of technological development and accelerates the growth of the use of modern techniques through the innovation of the digital economy in our daily lives. In addition, the modernization of companies in the field of E-marketing and E-commerce has a direct impact on the strategic relationship between internet users, information, technology and business. In this sense, my theoretical study determines methods and mechanisms of promotion through E-commerce and E-marketing during the revolution of the digital economy and the technologies of modern and social communication.

And Control

In this paper, we study the synchronization of two coupled nonlinear, in particular chaotic, systems which are not identical. We show how adaptive controllers can be used to adjust the parameters of the systems such that the two systems will synchronize. We use a Lyapunov function approach to prove a global result which shows that our choice of controllers will synchronize the two systems. We show how it is related to Huberman-Lumer adaptive control and the LMS adaptive algorithm. We illustrate the applicability of this method using Chua's oscillators as the chaotic systems. We choose parameters for the two systems which are orders of magnitude apart to illustrate the effectiveness of the adaptive controllers. Finally, we discuss the role of adaptive synchronization in the context of secure and spread spectrum communication systems. In particular, we show how several signals can be encoded onto a single scalar chaotic carrier signal.

While therapeutic interventions involving music have been shown to have benefits for people with dementia, little research has examined the role of music and music-related activities in their everyday lives. This paper presents the results of qualitative research that explored this role in terms of: the meaning and importance of music in everyday life; the benefits derived from participation in music-related activities; and the problems of engaging with music. Data were collected during in-depth interviews with 26 people with dementia and their carers, who lived either in their own homes or in residential care in different parts of England. The paper illustrates the many different ways in which people with dementia experience music. As well as being enjoyed in its own right, music can enable people to participate in activities that are enjoyable and personally meaningful. It is an important source of social cohesion and social contact, supports participation in various activities within and outside the household, and provides a degree of empowerment and control over their everyday situations. The practical implications for the provision of care and support for people with dementia are discussed. The scope and implications for technological development to promote access to music are also discussed.

The role of digital libraries in information generation,organization, dissemination and storage cannot be overemphasized. This article articulates the importance of digital libraries and the need to preserve them from disasters. It highlights the causes and effects of disasters in digital libraries. Prevention and management of disasters were also discussed. Issues and challenges around information and communication technology (ICT), that has direct bearings on digital libraries and disaster management in developing countries were raised. In addition, recommendations were made on how to improve on disaster prevention and control.

Summary Objectives: Intra-organizational communication is mostly interpersonal. Synchronous interruptive communication is recognized as aprimary source of inefficiency anderror in healthcare, and there is much potential for information and communication technology (ICT) to improve such communication. As recently suggested, however, due to communication failures ICT can also compound medical errors. In this paper we analyze factors that restrict the role of ICT in improving interpersonal healthcare communication and suggest solutions. Methods: We critically analyzed the literature from a selection of diverse scientific disciplines. These were related to interpersonal communication, tothe role and place of standardization and computerization in its improvement, and to reducing medical errors. Results: Four possible scenarios were defined on how ICT can serve healthcare communication. Two differing conceptual frameworks about communication in health-care were discussed. Considering “information space” as apart of “communication space ” allows the recognition and control of the source of the semantic gaps in conventional standardization and an enhancement of the role of ICT in improving intra-organizational communication. Moreover, cognitive, social, and organizational dimensions of complexity in interpersonal communication can be managed. Three approaches to control the variability in those dimensions and to promote therole of ICT in intra-organizational communication were discussed. Conclusion: A multi-dimensional approach is required to promote the role of ICT in intra-organizational communication in healthcare. Parallel to conventional standardization, atleast three dimensions need to be addressed: controlling the effect of the social context, developing standard information processing skills, and most importantly, controlling variations in care practices’ performance.

This paper explores ways in which academia could change to be more socially relevant in relation to communities ICT. It is intended to advance ideas and further discussion. Socially relevant means encouraging the creation of information and communication systems that support human development, social learning, collaborative problem-solving, self-governance — and civic intelligence generally. Because the build-out of these systems has such profound implications of surveillance and control that the early warning function is particularly critical.  This paper is primarily addressed to the academic community that focuses on the use of ICT in the social lives of "ordinary" citizens.
