Architecture for wireless grids

Evolving consumer expectations will require changes to the existing access network – next generation access networks (NGNs). Emerging services leads to a great increase in bandwidth demand. Another great challenge to access networks is mobility. By other side, wireless mobile devices have become an indispensable tool for households and businesses. The increase of wireless devices, motivated by the rapid decrease of the cost and ease installation, leads to the redesign of the way applications and services are delivered. So, the integration of wireless grids with NGNs is extremely important. This paper presents a new architecture to integrate wireless grids in access networks.info:eu-repo/semantics/publishedVersio

Zufuhrempfehlungen für ausgewählte Mineralstoffe im internationalen Vergleich

Diese Arbeit vergleicht die Empfehlungen und Upper Level von 16 Institutionen für 15 Mineralstoffe. Im Detail handelt es sich um Calcium, Phosphor, Magnesium, Eisen, Iod, Zink, Selen, Fluor, Kupfer, Mangan, Chrom, Molybdän, Natrium, Kalium und Chlor. Herangezogen wurden die Empfehlungen der Food and Agriculture Organization of the United Nations (FAO), der Europäischen Union, der D.A.CH. (Deutsche, Österreichische und Schweizerische Ernährungsgesellschaften), des Nordic Council of Ministers (eine Gemeinschaftsarbeit von Dänemark, Finnland, Island, Norwegen und Schweden), des US-amerikanischem Institute of Medicine (IOM), des australischen National Health and Medical Research Council, des britischem Committee on Medical Aspects of Food and Nutrition Policy, der Food Safety Authority of Ireland, der französischen Agence Francaise de securite sanitaire des Aliments, des belgischen Conseil Supérieur d'Hygiène, der italienischen Societá Italiana di Nutrizione Umana, der Chinese Nutrition Society, des japanischen Ministry of Health and Welfare, der Korean Nutrition Society, des philippinischen Food and Nutrition Research Institute und des malaysischen National Coordinating Committee on Food and Nutrition. Hiezu wurden vergleichende Tabellen der Mineralstoffempfehlungen, der Empfehlung pro Kilogramm Körpergewicht und der Energiedichte bezogen auf die empfohlene tägliche Energiezufuhr erstellt. Die Arbeiten des IOM dokumentieren wohl am umfangreichsten und werden, wie auch die der FAO, oft in anderen Publikationen zitiert. Bei der Betrachtung der einzelnen Empfehlungen ergibt sich ein sehr differenziertes Bild. Einerseits divergieren die scheinbaren Zielsetzungen der Arbeiten der einzelnen Institutionen, andererseits sind auch die Mineralstoffe unterschiedlich gut erforscht. Die teilweise recht starken Schwankungen der Empfehlungen können auf unterschiedliche Zielsetzungen, abweichende Referenzkörpergewichte, abweichende Sicherheitsfaktoren, und Einbeziehung der nationalen Gewohnheiten sowie genetischer Faktoren zurückgeführt werden.This thesis scrutinizes the recommendations and the “upper level” of 15 minerals (calcium, phosphorus, magnesium, iron, iodine, zinc, selenium, fluorine, copper, manganese, chrome, molybdenum, sodium, potassium and chlorine) published by 16 different institutions given below: The Food and Agriculture Organization of the United Nation (FAO), the European Union Commission (EC), the D.A.CH. (German, Austrian and Swiss Nutrition Societies), the Nordic Council of Minister (a joint venture work of Denmark, Finland, Iceland, Norway and Sweden), the US American Institutes of Medicine (IOM), the Australian National Health and Medical Research Council, British Committee on Medical Aspects of Food and Nutrition Policy, the Food Safety Authority of Ireland, the French Agence Francaise de Securite Sanitaire des Aliments, the Belgian Conseil Supérieur d' Hygiène, the Italian Societá Italiana di Nutrizione Umana, the Chinese Nutrition Society, the Japanese Ministry of Health and Welfare, the Korean Nutrition Society, the Philippine Food and Nutrition Research Institute and the Malaysian National Coordinating Committee on Food and Nutrition. On the basis of these studies comparative schedules have been developed to compare the mineral recommendations, the recommentations per kilogram body weight and the energy density in relation to the daily estimated energy requirement. The records published by the IOM are the most substantial and therefore are, together with those of the FAO, frequently referred to. Comparing individual recommendations in detail, some divergences become obvious. On one hand the apparent objectives diverge, on the other some minerals are investigated better than others. The reason for the partially significant inconsistencies between several recommendations might result from different goals of the studies, as well as from varying reference body weights, safety factors, national habits and genetic factors

A framework for integrated mobile content recommendation

Content filtering in a mobile recommendation system plays a vital role in providing solution to help mobile device users obtain their desire content. However, mobile content recommendation systems have problems and limitations related to cold start and sparsity. These problems can be viewed as a user’s first time connection to a mobile recommendation system and initial rating of the content in an early stage of the system. Hence, to obtain personalized content for mobile user, mobile content filtering is needed. This paper proposes a framework for integrated mobile content recommendation. The framework makes use of classification and adaptive association rule techniques to build an integrated model. The results demonstrate that the proposed framework outperforms related techniques. This can address the problem of sparsity for mobile content recommendation systems

Exploring Organizational Level Continuance of Cloud-Based Enterprise Systems

As cloud computing has become a mature technology broadly being adopted by companies across all industries, cloud service providers are increasingly turning their attention to retaining their customers. However, only little research has been conducted on investigating the antecedents of service continuance in an organizational context. To address this gap in research, we carried out a quantitative-empirical study. We developed a conceptual model that builds on previous research on organizational level continuance. We tested this model, using survey data gathered from IT decision makers of companies which have adopted cloud enterprise systems. The data was analyzed using PLS. The results show that continuance intention can be predicted both by socio-organizational and technology-related factors, explaining 55.9 % of the dependent variable’s variance. Besides cloud specific findings, the study also enhances knowledge in the area of organizational level system continuance as well as its connection to IS success

A review of cyber threats and defence approaches in emergency management

Emergency planners, first responders and relief workers increasingly rely on computational and communication systems that support all aspects of emergency management, from mitigation and preparedness to response and recovery. Failure of these systems, whether accidental or because of malicious action, can have severe implications for emergency management. Accidental failures have been extensively documented in the past and significant effort has been put into the development and introduction of more resilient technologies. At the same time researchers have been raising concerns about the potential of cyber attacks to cause physical disasters or to maximise the impact of one by intentionally impeding the work of the emergency services. Here, we provide a review of current research on the cyber threats to communication, sensing, information management and vehicular technologies used in emergency management. We emphasise on open issues for research, which are the cyber threats that have the potential to affect emergency management severely and for which solutions have not yet been proposed in the literature

Building a Smart E-Portfolio Platform for Optimal E-Learning Objects Acquisition

In modern education, an e-portfolio platform helps students in acquiring e-learning objects in a learning activity. Quality is an important consideration in evaluating the desirable e-learning object. Finding a means of determining a high quality e-learning object from a large number of candidate e-learning objects is an important requirement. To assist student learning in a modern e-portfolio platform, this work proposed an optimal selection approach determining a reasonable e-learning object from various candidate e-learning objects. An optimal selection approach which uses advanced information techniques is proposed. Each e-learning object undergoes a formalization process. An Information Retrieval (IR) technique extracts and analyses key concepts from the student’s previous learning contexts. A context-based utility model computes the expected utility values of various e-learning objects based on the extracted key concepts. The expected utility values of e-learning objects are used in a multicriteria decision analysis to determine the optimal selection order of the candidate e-learning objects. The main contribution of this work is the demonstration of an effective e-learning object selection method which is easy to implement within an e-portfolio platform and which makes it smarter
