The current technologies have made it possible to execute parallel applications across heterogeneous platforms. However, the performance models available do not provide adequate methods to calculate, compare and predict the applications performance on these platforms. In this paper, we discuss an enhanced performance evaluation model for parallel applications on heterogeneous systems. In our an...

To correctly evaluate learners’ knowledge, it is important to administer tests composed of good quality question items. By the term “quality” we intend the potential of an item in effectively discriminating between skilled and untrained students and in obtaining tutor’s desired difficulty level. This article presents a rule-based e-testing system which assists tutors in obtaining better questio...

learning rapidly and competently has become a pre-eminent strategy for improving organizational performance in the new knowledge era. improving dynamic learning capability is an exclusive strategy for corporate success in construction industry. thus engineering design firms should implement ol to accomplish a state of readiness for change and develop a competence to respond and identify future ...

this study a novel high performance liquid chromatography for the assay of nystatin in oral and vaginal tablets were optimized and validated using box–behnken experimental design. the method was performed in the isocratic mode on a rp-18 column (30 °c) using a mobile phase consisting of 0.05 m ammonium acetate buffer/ methanol mixture (30:70) and a flow-rate of 1.0 ml/min. the method was valida...

An application of relational instance-based learning to the complex task of expressive music performance is presented. We investigate to what extent a machine can automatically build ‘expressive profiles’ of famous pianists using only minimal performance information extracted from audio CD recordings by pianists and the printed score of the played music. It turns out that the machine-generated ...

of computer music systems based on AI techniques: (1) compositional, (2) improvisational, and (3) performance systems. Representative examples of each type are briefly described. Then, we look in more detail at the problem of endowing the resulting performances with the expressiveness that characterizes human-generated music. This is one of the most challenging aspects of computer music that ha...

We use an agent-based model to help to refine and clarify social practice theory, wherein the focus is neither on individuals nor on any form of societal totality, but on the repeated performances of practices ordered across space and time. The recursive relationship between social practices and practitioners (individuals performing practices) is strongly emphasised in social practice theory. W...

In this paper, the development and optimization of Power Distribution Control Strategy (PDCS) have been performed for a Hybrid Energy Storage Systems (HESS) of a Series Hybrid Electric Bus (SHEB). A common PDCS is based on the use of Ultra-Capacitor (UC) pack. A new simple PDCS is developed as a battery based one. For the battery based PDCS, four parameters ar...
