Digital telecommunication networks represent a fusion of concepts, techniques, and technologies from the fields of both communication and computing. The evaluation of such systems can likewise draw on methodologies which have evolved in both disciplines, bringing them together in a fashion that is suited to the needs of integrated services digital networks. With this aim, we discuss how quality...

Network virtualization can potentially overcome Internet ossification. This technology lets multiple virtual networks run on a shared physical infrastructure. A key step lies in mapping a virtual network request to a resource allocation in the network substrate. Previous approaches to this network embedding problem assumed the request will ask for specific resources, such as network bandwidth o...

Recent advances in wireless broadband networks and video coding techniques have led the rapid growth of wireless video services. In this chapter, we present a comprehensive study on the transmission of scalable video over wireless local area networks (WLAN). We analyze first the mechanisms and principles of the emerging scalable video coding (SVC) standard. We then introduce the IEEE 802.11 sta...

In this paper, we present a model of lean supplier management between an OEM and its suppliers for the objectives of eliminating wastes, reducing cost and improvement continuously based on the lean production. This model includes supplier selection and categorization, supplier improvement, supplier certification and supplier evaluation. First, the supplier selection process and some basic princ...

Traffic models are at the heart of any performance evaluation of telecommunication networks. An accurate estimation of network performance is critical for the success of broadband networks, which need to guarantee acceptable quality of service (QoS) to the users. A good traffic model should be accurate enough to capture the statistical characteristics of actual traffic, and at the same time sho...

Quality assurance (QA) tasks, such as testing, profiling, and performance evaluation, have historically been done in-house on developergenerated workloads and regression suites. Since this approach is inadequate for many systems, tools and processes are being developed to improve software quality by increasing user participation in the QA process. A limitation of these approaches is that they f...

this study aimed at investigating the effect of intellectual capital and organizational performance on service quality. research method was descriptive and correlation, structural equation modeling. the population consisted of all 219 male and female staff of sport and youth general offices in west azerbaijan province. 180 subjects were selected as the sample by purposive non-random sampling me...
