In this article, modeling and optimization of power consumption of two–stage compressed air system has been investigated. To do so, the two – stage compressed air cycle with intercooler of FAJR Petroleum Company was considered. This cycle includes two centrifugal compressors, a shell, and a tube intercooler. For modeling of power consumption, actual compressors isentropic efficiencies and inter...

Nowadays, the growing demand for supporting multiple applications causes to use multiple IPs onto the chip. In fact, finding truly scalable communication architecture will be a critical concern. To this end, the Networks-on-Chip (NoC) paradigm has emerged as a promising solution to on-chip communication challenges within the silicon-based electronics. Many of today’s NoC architectures are based...

The leakage power consumption increases with the scaling of the devices and it is expected that the leakage power consumption is important design constraint of total power consumption. In this proposed work , a new configuration of level shifter for low power high speed application has been presented. The proposed circuit have no cross coupled connection, by which there will be reduction in del...

Field Programmable Gate Arrays FPGAs are highly desirable for implementation of digital systems due to their flexibility, programmability and low end product life cycle. In more than 20 years since the introduction of FPGA, research and development has produced dramatic improvements in FPGA speed and area efficiency, narrowing the gap between FPGAs and ASICs and making FPGAs the platform of cho...

Increased power consumption is a critical concern for smartphone users. While multi-core processors in smartphones have already emerged in market, current applications are yet to take full advantage of this new architecture, particularly in the area of managing power consumption. This paper addresses the issue of managing power consumption in multicore smartphones via a middleware layer that sc...

ABSTRACT:The main objectives of any VLSI design are to achieve the low Power, minimum Delay and Area reduction. Minimizing power, delay & area is a challenge in the present situation, but all efforts to achieve one of these can lead to a better design. This paper proposes an EDA tool for low power/ high speed VLSI design, which solves any DFG to estimate the speed of operation and the percentag...

a laboratory stirred tank bioreactor with six single and dual-impeller configurations was tested to obtain the optimum operating conditions for future biological processes. six impeller combinations consisting of three basic impeller types, namely rushton turbine (rt), pitched 4blade (p4b) and pitched 2blade (p2b) downward flow were investigated in 1.77 l bioreactor working volume. power consum...

In this study, the stirring mechanism of shear-thinning fluids benefiting from four blades in turbulent flow is considered. The fluid is studied inside a stirred cylindrical tank with a flat bottom. The height of fluid is equal to the cylinder’s diameter and the impeller is positioned centrally. A CFD simulation has been carried out and three-dimensional turbulent flow is numerically analyzed u...
