The research has shown that these systems are vulnerable to hacking attacks that endanger anonymity of voters and correctness of results. The implementation of such e-voting systems using web-based technologies has recently become a hot topic. Helios is a web-based open-audit voting system designed by Adida at Harvard University. State of the art web technologies and advanced cryptographic techniques have been utilized to provide integrity of ballots and voter secrecy in the insecure Internet environment. However this book demonstrates that the matter of computer and web browser security has not been considered properly in this application. For this work, an attack is designed and implemented by exploiting both software and web browser vulnerabilities on client`s machine. Thus this gives an opportunity to an attacker to tamper with the integrity of an election. This book targets not only computer scientists and security professionals but also computer users. It shows the extend to which the vulnerabilities on client machines may risk the privacy of users on the Internet environment. ····· 1036189364
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Currently, business requirements for rapid operational efficiency, customer responsiveness as well as rapid adaptability are driving the need for ever increasing communication and integration capabilities of the software assets. Functional decomposition into re-usable software entities, loose coupling, and distribution of resources are all perceived benefits of the investment on Service Oriented Architecture (SOA). This malleability can also bring about the risk of a more difficult oversight. The same service is ideally used in different applications and contexts. This situation forces a supporting infrastructure to allow and manage the adaptability to these different contexts of use. In this book, the author proposes to govern such variations in a cost efficient way by composing the core business function offered by a service with other services implementing infrastructure capabilities that fulfill varying non-functional requirements. However, as the number of services increases and their use in different contexts proliferates, it becomes necessary to automate key management processes. ····· 1036189348
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The Sun is of fundamental importance to life on earth and is studied by scientists from many disciplines. It exhibits phenomena on a wide range of observable scales, timescales and wavelengths and due to technological developments there is a continuing increase in the rate at which solar data is becoming available for study which presents both opportunities and challenges. This book investigates the development of new technologies for processing information contained in multiple and overlapping images of the same scene to produce images of improved quality. This area in general is titled Super Resolution (SR), and offers a technique for reducing artefacts and increasing the spatial resolution. Another challenge is to generate 3D images such as Anaglyphs from uncalibrated pairs of SR images. An automated method to generate SR images is presented here. The SR technique consists of three stages: image registration, interpolation and smoothing. Then a method to produce enhanced, near real-time, 3D solar images from uncalibrated pairs of images is introduced. ····· 1036189346
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Properties are a very important commodity in any contemporary market. To find the right property for a targeted purpose still seems to be a hard task. With the development of computers and electronic information systems and with the evolution of the internet electronic property portals and databases have emerged. The search function within these databases is capable of producing fast results, but only results that match hard specified criteria. However, the need of a user is different as he seeks the best result according to his preferences. Currently no public property portal offers the possibility to accommodate user s preferences into the search. The approach of the user when searching for a property is shown. Theoretical analysis of this problem with mathematical possibilities of how to solve it is presented. Then a fuzzy approach to searching incorporating user preferences (with theoretical and practical background) is proposed. Finally the verification of the fuzzy logic approach is demonstrated and evaluated by the case study methodological approach, where contemporary traditional approach and the new fuzzy approach are compared. ····· 1036189343
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Functional verification is a widespread technique to check whether a hardware system satisfies a given correctness specification. As the complexity of modern hardware systems rises rapidly, it is a challenging task to find appropriate techniques for acceleration of this process. This thesis introduces a design of a verification framework that exploits the field-programmable gate array (FPGA) technology for cycle-accurate acceleration of simulation-based verification, while retaining the possibility to run verification also in the user-friendly debugging environment of a simulator. The presented framework is written in SystemVerilog and complies with the principles of functional verification methodologies (OVM, UVM) as well as assertion-based verification, making its application range quite large. According to the experiments carried out on a prototype implementation, the achieved acceleration is proportional to the number of checked transactions and the complexity of the verified system. The maximum acceleration achieved on the set of experiments was over 130 times. ····· 1036189306

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book is very useful for the scholars who are interested in the field of parallel computing at large and specifically in Opto-electronic Interconnection system (OTIS). OTIS has attracted many scientists and researches because of hybrid structure and hierarchical properties and extensive literature is also available. In this book, we have presented various parallel algorithms for problems including Lagrange interpolation, Durand-Kerner root finding, sorting, all-to-all communication, single-source shortest path routing and conflict graph construction on different OTIS models. In mapping these algorithms, intensive data movements are required over the intra-group links (electronic) as well as inter-group links (optical). Therefore, to analyze the time complexity of the proposed algorithms, we count the data movements through the electronic links as electronic moves and through the optical links as OTIS moves. We have also compared our work with the existing algorithms proposed by other scholars. This book will definitely motivate the scholars to explore all possible ways, an algorithm can be mapped on an OTIS model to improve the overall time complexity. ····· 1036189273
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book explores uses of ICT by women in an academic setting at Moi University, Kenya. It examines levels of computer literacy and use among female workers and students. It also highlights women s attitudes towards ICT in general and the extent to which they appreciate this technology. Reasons for non-use and barriers to use are also discussed. A survey of female students and staff revealed that there are fewer women in ICT related professions as compared to men. However, the study demonstrates that the trend is changing whereby women, especially the younger generation, are now proactive towards ICT. The author argues that women no longer view the use of computers as a men s only domain. She opines that to encourage increased usage, more training opportunities for all students, increased provision of computing resources, more opportunities for women ICT professionals, and changes at institutional level to facilitate more women participation in ICTs should be improved. The book is resourceful for students and scholars interested in ICT and gender issues. Policy makers at national and institutional levels will also find it useful. ····· 1036189244

Ontology and semantic web are the key factors in long-term sustainability towards the improvement of patient treatment process. Generally, researchers have the common consensus that knowledge is hard to capture due to its implicit nature, making it hard to manage. Medical professionals spend more time on getting the right information at the right moment, which is already available on intranet/internet. Evaluating the literature is controversial but interesting debates on ontology and semantic web encouraged me to propose a method and 4-Tier Architecture for retrieving context-based document according to user s information in healthcare organization. ····· 1036189179

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book presents a unified solution to the challenging problem of human action analysis in video. Human action is represented as a structured set of local features so that different structured learning models can be applied to classify and localise action instances in video databases. A wide range of factors for a good human action analysis is also analysed. At the feature level, different detectors, descriptors and selectors will be employed, while at the learning level, different types of models will be proposed and described. Lastly, at the evaluation level, a few different datasets will be used to analyse the applicability of each structured learning model under different test scenarios. The analysis obtained from this work has confirmed that the structured learning of local features is an effective potential approach for the task of analysing human action. It helps not only to create a significant bridge between traditional approaches of local and global features, but also to provide a foundational guideline for future work in this direction. Many other potential applications in visual pattern recognition can also be developed using the frameworks developed in this book. ····· 1036188580
