Grids, like other heterogeneous systems, have reached the level of maturity where they are addressing the Quality of Service (QoS) provision aspect as a fundamental part of their architecture. However, due to the multi-layer nature of these environments, the QoS characteristics of the infrastructure are revealed to the service-consumer through a complex procedure, in which each layer maps its o...

We are developing a distributed database, called BeeHive, which could offer features along different types of requirements: real-time, fault-tolerance, security, and quality-of service for audio and video. Support of these features and potential trade-offs between them could provide a significant improvement in performance and functionality over current distributed database and object managemen...

Class cohesion is an object-oriented software quality attribute and refers to the extent to which the members of a class are related. It is one of the fundamental measures of the goodness of a software design. Software developers use class cohesion measures to assess the quality of their products and to guide the restructuring of poorly developed software. To obtain a more comprehensive and mai...

Several tools have been developed for the estimation of software reliability. However, they are highly specialized in the approaches they implement and the particular phase of the software life-cycle in which they are applicable. There is an increasing need for a tool that can be used to track the quality of a software product during the software development process, right from the architectura...

Data streams in end-to-end communications can cross multiple network domains in which different QoS solutions are deployed. The provision of endto-end quality of service over heterogeneous environment assumes the negotiation of mutually acceptable SLA. The negotiation process gives the user the ability to specify the desired level of service, along with the permissible pricing of the service. T...

Late adolescents and emerging adults often report lower sleep quality. Recent studies have shown that many of these individuals are also characterized by ongoing development of executive functions (EFs), such as self-control and self-monitoring (SCSM). These functions are not fully mature until later in the 20s. As both suboptimal sleep and improper EFs can impact academic performance, there co...

We present a design process for incorporating data quality requirements into database schemas that is rooted in goal-oriented requirements analysis techniques, developed in the Requirement Engineering community over last 15 years. Goal-oriented approaches (i) offer a body of notations, techniques and processes for modeling, analyzing and operationalizing quality requirements; (ii) support repre...

In this article, the authors introduce the main ideas around the governance of cross-Cloud application deployment and their related concepts. It is argued that, due to the increasing complexity and nature of the Cloud market, an intermediary specialized in brokering the deployment of different components of a same application onto different Cloud products could both facilitate said deployment a...

Purpose: The purpose of this research was to evaluate the quality of work life and job burnout among public librarians of South Khorasan Province in Iran. Methodology:  we used survey method for this research. The population consisted of all librarians (110 person) working in public libraries in South Khorasan Province. 86 person selected with simple random method as sample. The “Walton” quest...

Many important scientific and engineering problems may be solved by combining multiple applications in the form of a Grid workflow. We consider that for the wide acceptance of Grid technology it is important that the user has the possibility to express requirements on Quality of Service (QoS) at workflow specification time. However, most of the existing workflow languages lack constructs for Qo...
