multivariate process capability indices (mpci) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. process capability is an important and commonly used metric for assessing and improving the quality of a production process. when quality charac-teristics of a product are correlated then an attractive comes close to mpc...

The main interconnecting device of today’s Internet the router, forwards IP packets without any true Quality of Service (QoS) considerations. This paper discusses a new approach for routing IP packets, which provides a basic QoS characteristic. It is shown that, by fine-tuning the parameters of a multi-port router, service discrimination can be achieved, according to the priority value set for ...

The IEEE 802.11e EDCF mechanism cannot guarantee the QOS of highpriority traffic as the bandwidth consumption of the low-priority traffic increases. Also, in the presence of high priority traffic dampen link utilization of low priority traffic. To overcome these problems, we propose the Novel mechanism in our research that extends IEEE 802.11e EDCF by introducing a Super Slot and Virtual Collis...

In this paper, we analyze the quality of a large class of simple dynamic resource allocation (DRA) strategies which we name priority planning. Their aim is to control an undesired diffusion process by distributing resources to the contagious nodes of the network according to a predefined priority-order. In our analysis, we reduce the DRA problem to the linear arrangement of the nodes of the net...

background due to the importance and uniqueness of the characteristics of the health sector, one of the most important priorities of the ministry of health is measuring the efficiency and quality of services which are provided for the people who refer to the health sectors. in all health systems, responding to the needs and wishes of patients is a crucial priority. objectives the main purpose o...

One of the key challenges in multimedia networks is video delivery over wireless channels. MRC (Multi-Resolution Coding) Layered video, divides video into a base layer and multiple enhancement layers. In this paper, we aim to improve video quality, impacted by high channel contention, through mapping individual video layers to EDCA (Enhanced Distributed Channel Access) access categories in orde...

One of the challenges that must be overcome to realize the practical benefits of ad hoc networks is quality of service (QoS). However, the IEEE 802.11 standard, which undeniably is the most widespread wireless technology of choice for WLANs and ad hoc networks, does not address this issue. In order to support applications with QoS requirements, the upcoming IEEE 802.11e standard enhances the or...
