In this paper, we would like to investigate the optimal wireless streaming of a multi-quality tiled 360 virtual reality (VR) video from server multiple users. To end, propose maximally exploit potential multicast opportunities by effectively utilizing characteristics VR videos and computation resources at users' side. particular, consider two requirements for quality variation in one field-of-v...

Requirement traceability supports several activities of software development processes such as impact analysis, requirement changes, maintenance, verification, and validation a system. For its effective use in those activities, the graphical representation data plays an important role. However, tools lack excellent visual to present these type data. Therefore, this paper presents framework whic...

The aim of this chapter is to provide a model for requirement specification, useful in developing efficient e-assessment applications with personalized feedback, which is enhanced by calling a recommender engine. The research was done in the context of using educational technology to facilitate learning processes. The data used to build the requirement model was collected from a set of intervie...

The concept of probabilistic argumentation systems PAS is restricted to two types of variables: assumptions, which model the uncertain part of the knowledge, and propositions, which model the rest of the information. Instantiations of PAS have been used for dealing with problems in different contexts. Here, we introduce a third kind of variables into PAS: so-called decision variables. This new ...

This paper presents the conceptual framework for sequencing of Participatory Action Research (PAR) methodology with the implementation of i* modeling framework in capturing multiple roles requirements. There are multiple roles involved in the development of information system, thus it involves with difference users requirements and preferences, context as well as the demands which become a chal...

With the development of information technology, the scale of current software is growing dramatically. This motivates the needs of techniques for intelligent software requirements engineering, which allows for modeling and analyzing requirements formally, rapidly and automatically, avoiding mistakes made by misunderstanding between engineers and users, and saving lots of time and manpower. In t...

All components have performance limitations. These limitations are due to part design, part misuse, manufacturing practices and material characteristics. Non-destructive examination is specified by designers and users to ensure that the component purchased does not have features that would limit the component performance to less than the design requirement. Radiography can be used to detect int...

To solve the problem of fuzzy and dynamics requirement caused by users’ cognitive bias, a dynamic priority capture method based on user scenarios is proposed, aiming at effectively improving experience. The consists following steps: Firstly, users with similar characteristics are filtered to form cluster, then obtain user’s product experience in different usage acquire preliminary requirements ...
