The adoption of register-transfer level (RTL) sign-off in ASIC design methodologies, and the increasing scale of system-on-chip integration, are leading to unprecedented accuracy and efficiency demands on RT-level estimation tools. In this work, we focus on the deployment of a simulation-based RTL power estimation tool in a commercial design flow, and describe several enhancements that improve ...

This paper presents an analysis of flow distribution in a newgeneration power supply used in telecommunication applications. The power supply involves several boards, each containing several magnetic components, EMI screens, and heat sinks, arranged in a rack. The flow in each passage is driven by four suitably placed fans. The study utilizes the technique of Flow Network Modeling (FNM) for eff...

Distributed flexible AC- transmission system (D-FACTS) is a recently advanced FACTS device with high flexibility and smaller size. The DPFC can control power flow in transmission lines, regulate bus voltages and it can also enhance stability margin in power grids. Adaptive-neural network-based fuzzy inference system (ANFIS) combines features of artificial neural network and fuzzy controller. Th...

In most of the digital systems the full-adders are the basic and the fundamental components. Due to the increase in number of transistors on the chip and its shrinkage has made the power consumption to be more. This power consumption is due to the flow of current and causes the battery life to be reduced. Hence the need of low power designs is the primary requirement in the VLSI field. The full...

This paper presents the simulation performance of Dual Active Bridge (DAB) DC-DC converter for high power density aerospace applications. The DAB converter topology has been chosen as it features high power density, high efficiency, bidirectional power flow capability, inherent soft switching, galvanic isolation and low number of passive components. Hence the converter is a candidate for high p...

Switching devices are key components in any power electronic circuit or system as they control and limit the flow of power from the source to the load. Their power level requirements (current & voltage) and switching frequency are continually increasing in the power electronic industry, and this demands larger and faster switching devices. This paper will focus on the development of high power ...

introduction nowadays, energy, water and environmental issues are the intersection of all human’s requisites. supplying energy from a wide range of clean sources is a reliable response in order to obtain all of the requisites of mankind. salinity gradient power is a clean energy source that is available everywhere and has the capacity of supplying a reasonable amount of energy suitable to be us...

In this study, an analysis of energy and exergy utilization in the utility sector of Jordan by considering the sectoral energy and exergy flows for the years 2007-2011 has been conducted based on real data obtained from main generators in Jordan. The overall energy and exergy efficiencies, for the entire utility sector, are found to be in the range of 35.1 to 38.1%. It is expected that the resu...

This paper presents a new framework for the day-ahead reactive power market based on the uniform auction price. Voltage stability and security have been considered in the proposed framework. Total Payment Function (TPF) is suggested as the objective function of the Optimal Power Flow (OPF) used to clear the reactive power market. Overload, voltage drop and voltage stability margin (VSM) are inc...

This paper explores the rationing of bed capacity in a cardiac intensive care unit (ICU). We find that the length of stay for patients admitted to the ICU is influenced by the occupancy level of the ICU. In particular, a patient is likely to be discharged early when the occupancy in the ICU is high. This in turn leads to an increased likelihood of the patient having to be readmitted to the ICU ...
