Fifty sampling stations have been identified and water samples were collected from June to May 2008, to know the groundwater quality of Greater Visakhapatnam city using Water Quality Index. The samples were analyzed for the physico-chemical parameters like Temperature, pH, Conductivity, Total dissolved solids, Dissolved Oxygen, Hardness, Calcium, Magnesium, Alkalinity, Chloride and Nitrate. The...

The total quality index (TQI) proposed in this study is an information technology-supported benchmarking tool that helps managers assess a total quality management program by enabling the cost-effective measurement of key organizational processes. TQI utilizes the analytic hierarchy process and the Delphi technique to measure ideal and actual quality management along eight critical factors synt...

The broadcast studios of today rely on expensive and proprietary communication means in order to network the large number of studio devices. Introducing an IP-based network in the studio environment is becoming an increasingly attractive solution, especially by using IP QoS solutions that are immediately available. In this paper, based on the requirements of a real broadcast studio we propose a...

Future integrated services networks will need to provide quality of service (QoS) guarantees to multimedia applications. To ensure that the contracted QoS is sustained, it is not sufficient to just commit resources. QoS monitoring is required to detect and locate the degradation of QoS performance. In addition, the distribution of QoS, instead of simply end-to-end QoS, needs to be monitored. In...

Having in mind that real-time streams tolerate some deadline misses according to (m,k)-firm constraints [1], this paper presents a solution that consists in integrating (m,k)-firm temporal requirements into the guaranteed– rate quality of service such as IntServ Model to provide both bandwidth and delay guarantees as required by real-time applications. Analytic study using Network Calculus give...

The development of scalable service models for integrated services networks is crucial for fostering interoperability and competition among multiple network service providers that support quality of service. A key scalability property of a service model is composability, which allows models for network elements in tandem to be lumped together into a composite model which is of the same type as ...

Recent technological advancements in wireless communication, integrated circuits and Micro-ElectroMechanical Systems (MEMs) has enabled miniaturized, lowpower, intelligent, invasive/ non-invasive micro and nanotechnology sensor nodes placed in or on the human body for use in monitoring body function and its immediate environment referred to as Body Area Networks (BANs). BANs face many stringent...
