In this paper, we look at power optimization issues under dual supply voltage environment, with the goal of optimizing power consumption due to interconnection and gate capaci-tances. Logic level synthesis is used as a good starting point for power reduction, while subsequent placement stage mod-iies or veriies logic level design by providing more accurate estimate of power dissipation. We try ...

With the increase of sensitive loads and, in many cases, causing disturbances in distribution systems, power quality monitor allocation has become a subject with increasingly importance. Therefore, it becomes necessary to have well-formed strategies to allocate such equipment, since they have high cost that needs to be minimized. With this objective, this research provides a methodology for mon...

In previous work we have proposed a distributed security logic for authorizing code. To gain assurance about the correctness of the implementation of our system, we now present a series of security logics of increasing expressive power leading up to our logic. We encode each logic in Coq, develop an algorithm for deciding queries, and prove properties about the algorithm in Coq. By using Coq’s ...

Power Quality assessment is today one of the main ways to improve energy efficiency. International standards tend to restrict the way this assessment is done, by defining the measurements methods that should be adopted by an instrument. This work describes some of the constrictions and requirements assumed for the design of the high performance Power Quality data logger PQ1000, taking into acco...

In recent years, data broadcasting becomes a promising technique to design a mobile information system with power conservation, high scalability and high bandwidth utilization. However, most of the prior research works in data broadcasting are based on the assumption that the disseminated items are independent of one another. Since in many applications, a mobile user will be interested in more ...

Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

As Distribution Systems are growing large and being stretched too far, electric utilities and end users of electric power are becoming increasingly concerned about meeting the growing electric demand. Hence efforts have been made by electric utilities to reduce the losses in the distribution system. In this dissertation work, Network Reconfiguration and Optimal Distributed Generation placement ...

background and objective: the reliability and validity of monitors for self-monitoring of blood glucose are debated. we evaluated the analytical performance of accu-check active (boehringer mannheim, roche) which is one of the most commonly used monitors in iran. material and methods: we compared the monitor readings with the reference values by percentage of values within certain intervals of...

Power quality (PQ) monitoring is important for both the utilities and also users of electric power. The most widespread measurement instrument used PQ PQM (Power Quality Monitor) or PQA Analyzer). In this paper we propose usage PMU data parameters monitoring. We present a new methodology classification based on data. proposed tested with real measurements performed in distribution system using ...
