As the field of Usability engineering gains more importance day by day, the phenomenon of testing the Usability of software and hardware products is becoming popular too. But, in presence of so many usability testing techniques, selecting an assessment parameter for performing usability testing is considered to be a great challenge for testers. The aim of this research is to suggest usability heuristics as an assessment parameter to Usability testing. To achieve the aim and objectives of this research, renowned Usability expert Jakob Nielsen's 10 Usability Heuristics have been chosen for assessing usability of some public sectors universities websites. In the second step, by using these Heuristics as an assessment parameter, Usability Survey and Heuristic Evaluation techniques are applied on these websites. It has been found that Heuristics are key attributes of software products and considered good measuring parameters to assess usability. Meanwhile this research is also a contribution towards rating the Usability of some academic websites. And hence, in this research, Usability Heuristics have been chosen as an assessment parameter for performing Usability Testing.
GPUs are many-core processors with tremendous computational power. However, as automatic parallelization has not been realized yet, developing high-performance parallel code for GPUs is still very challenging. The pap...

Computers can be used more effectively for constructive work instead of just chatting and games. This paper talks about our efforts in introducing computers to junior high school students (eighth grades) as more creative learning tools in a fun way. A visual programming curriculum utilizing an autonomous robot was developed. Both the course design and the teaching materials are discussed in the paper. Moreover, the before and after difference in taking the course is shown by conducting survey and data analysis on them. The results show that after taking the course, most junior high school students were able to experience the broad view of usage of computer other than just thinking of computer as tools for recreational activities such as gaming and chatting.
To deal with the model checking issue of rectangular hybrid systems, a constraint system called hybrid zone is introduced for the representation and manipulation of rectangular hybrid automata state-spaces. Model chec...

Requirements specification should not be concerned only with the software specification, but should also be able to integrate with the organizational models describing the environment in which the system will function. Agent-oriented conceptual modeling notations such as i* represents an interesting approach for modeling early phase requirements which includes organizational contexts, stakeholder intentions and rationale. Business Process Modeling notations such as BPMN are used to effectively conceptualize and communicate important process characteristics to relevant stakeholders. On the other hand, Unified Modeling Language (UML) is suitable for later phases of requirement capture which usually focus on completeness, consistency, and automated verification of functional requirements for the new system. In this paper, we illustrate the use of a methodology that facilitate and support the combined use of notation for modeling requirement engineering process in a synergistic fashion in a complex project for a large government Department. The notations we used were i*, BPMN and UML Use Case.

Dedicated computing clusters are typically sized based on an expected average workload over a period of years, rather than on peak workloads, which might exist for relatively short times of weeks or months. Recent work has proposed temporarily adding capacity to dedicated clusters during peak periods, by purchasing additional resources from Infrastructure as a Service (IaaS) providers such as Amazon's EC2. In this paper, we consider the economics of purchasing such resources by taking advantage of new opportunities offered for renting virtual infrastructure such as the spot pricing model introduced by Amazon. Furthermore, we define different provisioning policies and investigate the use of spot instances compared to normal instances in terms of cost savings and total breach time of tasks in the queue.
