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
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
q-Differential equations for q-classical polynomials and q-Jacobi-Stirling numbers
No full textWe introduce, characterise and provide a combinatorial interpretation for the so-called q-Jacobi–Stirling numbers.
This study is motivated by their key role in the (reciprocal) expansion of any power of a second order
q-differential operator having the q-classical polynomials as eigenfunctions in terms of other even order operators,
which we explicitly construct in this work. The results here obtained can be viewed as the q-version of
those given by Everitt et al. and by the first author, whilst the combinatorics of this new set of numbers is a
q-version of the Jacobi–Stirling numbers given by Gelineau and the second author

Tobin's Q and Financial Policy
No full textRecent research in macroeconomics has emphasized the importance of linking the financial and real sectors and the need for working with optimizing models. Tobin’s Q model of investment would appear to provide a framework that can satisfy these two criteria. In contrast to the original presentation of the Q model, the formal development has not recognized that the firm actively participates in a number of financial markets; in this broader context, we show that Q is likely to be an uninformative and possibly misleading signal for investment expenditures . We then endeavor to turn this negative theoretical result to positive advantage in resolving a number of empirical problems with Q models, but the modifications dictated by the theory receive little support from the data.
A Q-learning based multi-strategy integrated artificial bee colony algorithm with application in unmanned vehicle path planning
No full textArtificial bee colony (ABC) is a prominent algorithm that offers great exploration capabilities among various meta-heuristic algorithms. However, its monotonous and one-dimensional search strategy limits its searching performance in the solving process. Thus, to address this issue, a Q-learning based multi-strategy integrated ABC algorithm (QMABC) is proposed. In the QMABC, multiple search strategies are proposed to utilize different individual experiences and search approaches for solution updates. Then, Q-learning is employed for strategy selection. In comparison to previous studies, this paper introduces more effective state and action configurations within the framework of Q-learning. To evaluate the performance of the QMABC, CEC 2017 benchmark functions are adopted to compare it to different meta-heuristic algorithms including ABC based and non-ABC based algorithms. Moreover, applications in path planning are implemented to further verify the effectiveness of the QMABC. Overall, it should be highlighted that the proposed QMABC demonstrates superiority in both numerical and practical experiments.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Discrete Mathematics and Optimizatio
