Nowadays, digital computer systems and networks are the main engineering tools, being used in planning, design, operation, and control of all sizes of building, transportation, machinery, business, and life maintaining devices. Consequently, computer viruses became one of the most important sources of uncertainty, contributing to decrease the reliability of vital activities. A lot of antivirus programs have been developed, but they are limited to detecting and removing infections, based on previous knowledge of the virus code. In spite of having good adaptation capability, these programs work just as vaccines against diseases and are not able to prevent new infections based on the network state. Here, a trial on modeling computer viruses propagation dynamics relates it to other notable events occurring in the network permitting to establish preventive policies in the network management. Data from three different viruses are collected in the Internet and two different identification techniques, autoregressive and Fourier analyses, are applied showing that it is possible to forecast the dynamics of a new virus propagation by using the data collected from other viruses that formerly infected the network.

AbstractLithium-ion battery energy storage systems (Li-ion BESS), due to their capability in providing both active and reactive power services, act as a bridging technology for efficient implementation of active network management (ANM) schemes for land-based grid applications. Due to higher integration of intermittent renewable energy sources in the distribution system, transient instability may induce power quality issues, mainly in terms of voltage fluctuations. In such situations, ANM schemes in the power network are a possible solution to maintain operation limits defined by grid codes. However, to implement ANM schemes effectively, integration and control of highly flexible Li-ion BESS play an important role, considering their performance characteristics and economics. Hence, in this paper, an energy management system (EMS) has been developed for implementing the ANM scheme, particularly focusing on the integration design of Li-ion BESS and the controllers managing them. Developed ANM scheme has been utilized to mitigate MV network issues (i.e. voltage stability and adherence to reactive power window). The efficiency of Li-ion BESS integration methodology, performance of the EMS controllers to implement ANM scheme and the effect of such ANM schemes on integration of Li-ion BESS, i.e. control of its grid-side converter (considering operation states and characteristics of the Li-ion BESS) and their coordination with the grid side controllers have been validated by means of simulation studies in the Sundom smart grid network, Vaasa, Finland.

In the era of big data, social network has become an important reflection of human communications and interactions on the Internet. Identifying the influential spreaders in networks plays a crucial role in various areas, such as disease outbreak, virus propagation, and public opinion controlling. Based on the three basic centrality measures, a comprehensive algorithm named PARW-Rank for evaluating node influences has been proposed by applying preference relation analysis and random walk technique. For each basic measure, the preference relation between every node pair in a network is analyzed to construct the partial preference graph (PPG). Then, the comprehensive preference graph (CPG) is generated by combining the preference relations with respect to three basic measures. Finally, the ranking of nodes is determined by conducting random walk on the CPG. Furthermore, five public social networks are used for comparative analysis. The experimental results show that our PARW-Rank algorithm can achieve the higher precision and better stability than the existing methods with a single centrality measure.

Analysis of the Slovak Discourses of Sex Education Inspired by Michel FoucaultThe aims, rules and topics of sex education exist on paper, but have yet to be implemented in Slovakia. Although the curriculum creates the illusion of openness in this field, the silence on sex education in schools provides space for the alternative, "more valuable" quiet discourses of religious education. Under these conditions, it is silence that is proving to be an advantageous strategy for the majority of those who should be voicing their opinions. Instead, they listen and control. By contrast, those who do speak out, children and young people, do not in fact, speak to them, but mainly among themselves. Those who are silent and listen are not prepared for the younger generations confessions on sexuality, which are mostly taken from the liberal area of media, especially the internet. The silent frequently lack, at the very least, the basic ability to react and debate in this changed situation. Those who are involved in the discussion on sexuality in Slovakia are those who should listen and supervise.

The development of information and computerized tenology has led to what is called the Internet and the World Wide Web (WWW). In addition, the dramatic development of the Internet has given users more choice and control over content, and also provides individuals, businesses, and public and private organizations with the opportunity to generate and disseminate information. The interactive features of the web can be an effective way to build and maintain mutually beneficial relationships if the web is used properly. The presence of the Internet has proven to have a positive impact on the development of a village, sub-district or district to introduce and inform the potential of its region. This is evident in several regions of Indonesia which have successfully used Internet facilities to introduce tourist destinations to the world. Therefore, the training on the promotion website is an effort to optimize the introduction of high quality village products in the district of Patuk and is also intended to follow the results of research on the design of a promotion of superior products and tourist objects on the web in Patuk Gunungkidul district. On the basis of the website promotion feasibility test during the training for each representative in 11 villages in the Patuk sub-district, 87.36% was obtained, so that it can be said that the Introduction of superior village products via promotional materials based on the website was optimal and met the needs of users.

This study aims to examine the cross-cultural adjustment processes of trainees with disabilities from Asia-Pacific regions, with the aim to explore factors that influence cross-cultural adjustments and uncover experiences by individuals with disabilities. We interviewed a total of 13 trainees, some of whom were interviewed multiple times. Several factors (e.g., affluence of the Japanese lifestyle, maintaining contact with home via the Internet, and/or previous knowledge of the host culture) greatly affected their transitions to Japan. Notably, participant adjustments were made on several different levels, including physical, social, and attitudinal.

Much communications research is in agreement about the failure of mass media to adequately facilitate a public sphere of open and reflexive debate necessary for strong democratic culture. In contrast , the internet's decentralised, two-way communication is seen by many commentators to be extending such debate. However, there is some ambivalence among critical theorists as to the future role of the internet in advancing the public sphere. On the one hand, the internet is providing the means fot the voicing of positions and identities excluded from the mass media. On the other hand, a number of problem are limiting the extensiveness and effetivness of this voicing. One of the most significant problems is the corporate colonisation of cyberspace, and subsequent marginalisation rational-critical communication. It is this problem that i will focus on in this article, with reference to examples from what I refer to as the 'New Zealand online public sphere'. I show how online corporate portals and media sites are gaining the most attention orientated to public communication, including news, information, and discussion. These sites generally support conservative discourse and consumer practices. The result is a marginalisation online of the very voices marginalised offline, and also of the critical-reflexive form of communication that makes for a strong public sphere. I conclude by noting that corporate colonisation is as yet only partial, and control of attention and media is highly contested by multiple 'alternative' discursive spaces online.
