Semantic adaptability for the systems interoperability

In the current global and competitive business context, it is essential that enterprises adapt their knowledge resources in order to smoothly interact and collaborate with others. However, due to the existent multiculturalism of people and enterprises, there are different representation views of business processes or products, even inside a same domain. Consequently, one of the main problems found in the interoperability between enterprise systems and applications is related to semantics. The integration and sharing of enterprises knowledge to build a common lexicon, plays an important role to the semantic adaptability of the information systems. The author proposes a framework to support the development of systems to manage dynamic semantic adaptability resolution. It allows different organisations to participate in a common knowledge base building, letting at the same time maintain their own views of the domain, without compromising the integration between them. Thus, systems are able to be aware of new knowledge, and have the capacity to learn from it and to manage its semantic interoperability in a dynamic and adaptable way. The author endorses the vision that in the near future, the semantic adaptability skills of the enterprise systems will be the booster to enterprises collaboration and the appearance of new business opportunities

Evaluation and improvement on service quality of Chinese university libraries under new information environments.

The rapid development of information technology in the recent years has added a range of new featuresto the traditional information environment, which has a profound impact on university library services and users. The Quality of Service parameter in library services has reached a broader consensus,which directly reflects customer satisfactions and loyalty. Exploring the evaluation frameworks for service quality in university libraries cannot be undermined in this context. Besides, existing evaluation frameworks of service quality of university library services are also facing numerous challenges due to their imperfections. Thus,there is an urgency and necessity to explore and enhance the efficiencies of the evaluation frameworks of service quality. To this end, this thesis conducts a systematic analysisof evaluation frameworks with a motivation of identifying the core components that needs enhancements for achieving effective service quality in Chinese university libraries through empirical methods. Furthermore, the inferences extracted from the analysis has been exploited to provide suitable recommendations for improving the service quality of university libraries.N/

Security Enhanced Applications for Information Systems

Every day, more users access services and electronically transmit information which is usually disseminated over insecure networks and processed by websites and databases, which lack proper security protection mechanisms and tools. This may have an impact on both the users’ trust as well as the reputation of the system’s stakeholders. Designing and implementing security enhanced systems is of vital importance. Therefore, this book aims to present a number of innovative security enhanced applications. It is titled “Security Enhanced Applications for Information Systems” and includes 11 chapters. This book is a quality guide for teaching purposes as well as for young researchers since it presents leading innovative contributions on security enhanced applications on various Information Systems. It involves cases based on the standalone, network and Cloud environments

Knowledge management framework based on brain models and human physiology

The life of humans and most living beings depend on sensation and perception for the best assessment of the surrounding world. Sensorial organs acquire a variety of stimuli that are interpreted and integrated in our brain for immediate use or stored in memory for later recall. Among the reasoning aspects, a person has to decide what to do with available information. Emotions are classifiers of collected information, assigning a personal meaning to objects, events and individuals, making part of our own identity. Emotions play a decisive role in cognitive processes as reasoning, decision and memory by assigning relevance to collected information. The access to pervasive computing devices, empowered by the ability to sense and perceive the world, provides new forms of acquiring and integrating information. But prior to data assessment on its usefulness, systems must capture and ensure that data is properly managed for diverse possible goals. Portable and wearable devices are now able to gather and store information, from the environment and from our body, using cloud based services and Internet connections. Systems limitations in handling sensorial data, compared with our sensorial capabilities constitute an identified problem. Another problem is the lack of interoperability between humans and devices, as they do not properly understand human’s emotional states and human needs. Addressing those problems is a motivation for the present research work. The mission hereby assumed is to include sensorial and physiological data into a Framework that will be able to manage collected data towards human cognitive functions, supported by a new data model. By learning from selected human functional and behavioural models and reasoning over collected data, the Framework aims at providing evaluation on a person’s emotional state, for empowering human centric applications, along with the capability of storing episodic information on a person’s life with physiologic indicators on emotional states to be used by new generation applications

Increasing the robustness of networked systems

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2009.Includes bibliographical references (p. 133-143).What popular news do you recall about networked systems? You've probably heard about the several hour failure at Amazon's computing utility that knocked down many startups for several hours, or the attacks that forced the Estonian government web-sites to be inaccessible for several days, or you may have observed inexplicably slow responses or errors from your favorite web site. Needless to say, keeping networked systems robust to attacks and failures is an increasingly significant problem. Why is it hard to keep networked systems robust? We believe that uncontrollable inputs and complex dependencies are the two main reasons. The owner of a web-site has little control on when users arrive; the operator of an ISP has little say in when a fiber gets cut; and the administrator of a campus network is unlikely to know exactly which switches or file-servers may be causing a user's sluggish performance. Despite unpredictable or malicious inputs and complex dependencies we would like a network to self-manage itself, i.e., diagnose its own faults and continue to maintain good performance. This dissertation presents a generic approach to harden networked systems by distinguishing between two scenarios. For systems that need to respond rapidly to unpredictable inputs, we design online solutions that re-optimize resource allocation as inputs change. For systems that need to diagnose the root cause of a problem in the presence of complex subsystem dependencies, we devise techniques to infer these dependencies from packet traces and build functional representations that facilitate reasoning about the most likely causes for faults. We present a few solutions, as examples of this approach, that tackle an important class of network failures. Specifically, we address (1) re-routing traffic around congestion when traffic spikes or links fail in internet service provider networks, (2) protecting websites from denial of service attacks that mimic legitimate users and (3) diagnosing causes of performance problems in enterprises and campus-wide networks. Through a combination of implementations, simulations and deployments, we show that our solutions advance the state-of-the-art.by Srikanth Kandula.Ph.D

Factors Influencing Customer Satisfaction towards E-shopping in Malaysia

Online shopping or e-shopping has changed the world of business and quite a few people have decided to work with these features. What their primary concerns precisely and the responses from the globalisation are the competency of incorporation while doing their businesses. E-shopping has also increased substantially in Malaysia in recent years. The rapid increase in the e-commerce industry in Malaysia has created the demand to emphasize on how to increase customer satisfaction while operating in the e-retailing environment. It is very important that customers are satisfied with the website, or else, they would not return. Therefore, a crucial fact to look into is that companies must ensure that their customers are satisfied with their purchases that are really essential from the ecommerce’s point of view. With is in mind, this study aimed at investigating customer satisfaction towards e-shopping in Malaysia. A total of 400 questionnaires were distributed among students randomly selected from various public and private universities located within Klang valley area. Total 369 questionnaires were returned, out of which 341 questionnaires were found usable for further analysis. Finally, SEM was employed to test the hypotheses. This study found that customer satisfaction towards e-shopping in Malaysia is to a great extent influenced by ease of use, trust, design of the website, online security and e-service quality. Finally, recommendations and future study direction is provided. Keywords: E-shopping, Customer satisfaction, Trust, Online security, E-service quality, Malaysia
