Development of Hypervideo Platform Using Object Databases
No full textWeb users are seizing on interactive capabilities that software suppliers have developed so far, and are eagerly awaiting new interactive capabilities now being demonstrated. This paper focuses the development of rich information environment based on a customized platform enabling hyperlinks on objects within a digital video. With the help of such environment, the viewer is able to view multiple videos concurrently and browse them temporally as well as spatially with the help of an object database. Specifically, the platform enables to traverse through that object by linking, and such links have been explored and created. The link may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base (static, generic or dynamic) and object database versus multiple videos are also investigated
Semantic Web Approach to Academic Program Assessment
No full textGenerally, the engineering program assessment process in line with an accreditation body involves some cyclic and tiring paperwork before any weakness is identified in the system. Additionally, the current state of such systems is that the assessment data are spread over many sub-systems, and there is no way to use them intelligently for better academic process management. It has been a desire of academic institutions to develop these processes in such a way that program management is also facilitated through an integrated system connecting all stakeholders of the program. This paper describes an electrical engineering program assessment process that has been developed and implemented using web semantics to provide intelligent services through an integrated system. The integrated system provides a value-added semantics layer where activities such as annotation, querying and reasoning can be carried out to support management. The framework is developed with a case study of a United Arab Emirates (UAE) University program assessment process to show how semantic web technologies can be used to facilitate program management
Object-database approach for a hypervideo platform
No full textWeb users are seizing on interactive capabilities that software suppliers have developed, and are eagerly awaiting new interactive capabilities now being demonstrated. The capabilities currently being explored include video browsing. This paper focuses on the development of a rich information environment based on a customized platform that enables hyperlinks on objects within a digital video. With the help of such an environment, the user is able to view multiple videos concurrently and browse them spatially and temporally, with the help of an object database. Specifically, the platform is expected to enable users to traverse through that object by linking, and such links have been explored. The links may connect to within a video, or multiple running videos and/or World Wide Web object. The issues such as open hypermedia link base and object database versus multiple videos are also investigated

Advanced Thermoelectric Materials for Energy Harvesting Applications
No full textElectrical energy consumption is negatively affecting our environment and contributing to climate change. Therefore the research and industrial communities are working hard to minimize energy consumption using promising energy-efficient and renewable energy technologies. We know that it is possible to convert heat energy into electrical energy using thermoelectric devices; this heat energy can be from the sun or from an electro-mechanical device. However, thermoelectric devices traditionally suffer from lower efficiencies of energy conversion. This book, Advanced Thermoelectric Materials for Energy Harvesting Applications, is a researchintensive textbook consisting of eight chapters organized into three sections. Section 1 consists of Chapters 2, 3, and 4, which cover advanced thermoelectric materials and the topics of organic/inorganic thermoelectric materials, quantum theory of the Seebeck coefficient for the advancement of thermoelectric superconducting material, and the limits of Bismuth Telluride-based thermoelectric materials. Section 2, containing Chapters 5 and 6, evaluates behaviors and performance of
thermoelectric devices. Section 3, containing Chapters 7 and 8, focuses on energy harvesting applications of thermoelectric devices. This book will be of interest to a wide range of individuals, such as scientists, engineers, researchers, and undergraduate and postgraduate students in the field of advanced thermoelectric materials
Are Two Interviews Better Than One? Memory across Repeated Cognitive Interviews.
No full textEyewitnesses to a filmed event were interviewed twice using a Cognitive Interview to examine the effects of variations in delay between the repeated interviews (immediately & 2 days; immediately & 7 days; 7 & 9 days) and the identity of the interviewers (same or different across the two repeated interviews). Hypermnesia (an increase in total amount of information recalled in the repeated interview) occurred without any decrease in the overall accuracy. Reminiscence (the recall of new information in the repeated interview) was also found in all conditions but was least apparent in the longest delay condition, and came with little cost to the overall accuracy of information gathered. The number of errors, increased across the interviews, but the relative accuracy of participants' responses was unaffected. However, when accuracy was calculated based on all unique details provided across both interviews and compared to the accuracy of recall in just the first interview it was found to be slightly lower. The identity of the interviewer (whether the same or different across interviews) had no effects on the number of correct details. There was an increase in recall of new details with little cost to the overall accuracy of information gathered. Importantly, these results suggest that witnesses are unlikely to report everything they remember during a single Cognitive Interview, however exhaustive, and a second opportunity to recall information about the events in question may provide investigators with additional information
XML Implementation of Role Based Control in Healthcare Adhoc Networks
No full textAs mobile adhoc networks (MANETs) are becoming popular for a variety of applications, so are the issues engulfing corresponding implementations. In this paper, a healthcare application is described for the environment where normal network connectivity may not be available hence adhoc networking of small scale healthcare units and corresponding devices becomes necessary. Different roles of such units are discussed to develop policy framework to facilitate role based access control conformant access. Furthermore, implementation of such access control within a typical healthcare environment is investigated
RBAC and XML Security in Adhoc Networks
No full textAs adhoc networks are becoming increasingly important for variety of applications, so are the rules and specifications for their formations and operations. In this paper, we describe how roles of participating devices can be framed to facilitate access and formation of an adhoc network. Further, we propose XML framework for secured file transfer in a typical case where adhoc network nodes exchange files and data among themselves. We also show corresponding XML pseudo-code in the light of world-wide-web consortium (W3C)guidelines
