The increased need for Quality of Service (QoS) in today’s networks has concentrated a lot of research and implementation efforts. Particular interest exists for the exploitation of the DiffServ framework towards the provision of qualitative services in MANs and WANs worldwide. Although individual mechanisms have been widely investigated, not many references to studies combining all levels of p...

One of the major issues related to the environment in the 21st century is sustainable development. The innovative economic growth policy has supported relatively successful economic development, but poor environmental conservation efforts, have consequently resulted in serious water quality pollution issues. Hence, assessments of water quality and health are fundamental processes towards conser...

Based on SERVAUALmodel, this paper brings in the entropy method to rank quality improvement (QI) priority for service attributes, and a service quality evaluation(SQE) model integrating competitive analyses has been structured to evaluate the mobile communication service quality (SQ) for Wuhan Branch of China Telecom(WBCT). The research shows that the QI priority of 22 service attributes has ch...

In order to deliver a qualitative Internet Protocol Television (IPTV) service over vehicular ad hoc networks (VANETs), a quality of service (QoS) mechanism is needed to manage the allocate of network resources to the diverse IPTV application traffic demands. Unlike other mobile network, VANETs have certain unique characteristic that presents several difficulties in providing an effective QoS. S...

The Emerging Need for High-Speed Token Ring, Today’s High-Speed Options for Token Ring Users, The Technology and Timescales of High-Speed Token Ring, Defining the Requirements for High-Speed Token Ring, High-Speed Token Ring and Virtual LANs, High-Speed Token Ring and Quality of Service, Priority Access for Voice and Video Traffic, Packet Priority and Token Ring Switches, Packet Priority and Hi...

The paper presents a quality of service aware routing protocol which provides low latency for high priority packets. Packets are differentiated based on their priority by applying queuing theory. Low priority packets are transferred through less energy paths. The sensor nodes interact with the pivot nodes which in turn communicate with the sink node. This protocol can be applied in monitoring c...

In this paper, we develop an optimization model for the economic design of repetitive sampling plan in the presence of two markets. The process under consideration produces a product with a normally distributed quality characteristic with unknown mean and known variance. The quality characteristic has a lower specification limit. The quality of the product is controlled via lot-by-lot acceptanc...

Electronic health record (EHR) systems support local quality improvement efforts by health care organizations and provide the opportunity to address national priority areas for quality measurement, such as specialty care, overuse and efficiency, coordination of care, change over time and patient- reported outcomes (PROs). However, variations in provider workflow and documentation habits, adopti...
