When large capacity distributed generation including photovoltaic (PV) systems are installed in power systems, reverse power flow from PV systems may cause problem of surplus electric power. To reduce the reverse power flow without the reduction of PV power generation, energy management of customer equipment such as electric water heater is one of the solutions. Therefore, cooperative control o...

Reverse osmosis is a commonly used process in water desalination. Due to the scarcity of freshwater resources and wastewater problems, a lot of theory and experimental studies have been conducted to optimize this process. In the present study, the performance of reverse osmosis membrane module of salt–water separation was simulated based on computational fluid dynamics technique and solution-di...

Doppler indexes have been used successfully to determine the severity of aortic regurgitation (AR) in adults but have not been evaluated in children. To determine the accuracy of pulsed, color, and continuous-wave (CW) Doppler echocardiographic indexes in assessing the degree of AR in children, the correlation between the non-invasive measurements and angiographic grading of the regurgitant flo...

Simple and sensitive normal and reverse flow injection methods for spectrophotometric determination of thiamine hydrochloride (THC) at the microgram level were proposed and optimized. Both methods are based on the reaction between THC and diazotized metoclopramide in alkaline medium. Beer's law was obeyed over the range of 10-300 and 2-90 μg/mL, the limits of detection were 2.118 and 0.839 μg/m...

Power plant generators are important components of an electrical energy system. They should be constantly monitored and protected in order to maintain the quality reliability power supply. Otherwise generator may operate incorrectly resulting poor instability during events like faults, equipment failure, reverse flow(RPF) etc., presence large distributed resources is major cause flow low loads/...

The liquid streams in a microchannel are hardly mixed to form laminar flow, and the mixing issue is well described by a low Reynolds number scheme. The staggered herringbone mixer (SHM) using repeated patterns of grooves in the microchannel have been proved to be an efficient passive micro-mixer. However, only a negative pattern of the staggered herringbone mixer has been used so far after it w...

Background & objectives: Nowadays, according to membrane-based filtration processes; the use of substances such as antiscalants that prevents the formation of deposits during the treatment process, is very important from industrial point of view. This study aimed to synthesize styrene-maleic anhydride copolymer (PSMA) using the radical polymerization method and to investigate the factors and pa...

Software obfuscation is intended to protect a program by thwarting reverse engineering. Several types of software obfuscation have been proposed, and control-flow obfuscation is a commonly adopted one. In this paper, we present a framework to evaluate parallel control-flow obfuscation, which raises difficulty of reverse engineering by increasing parallelism of a program. We also define a contro...

[1] Standing well above the trade wind inversion, Hawaii Island (maximum elevation 4.2 km) splits the northeast trade winds and induces a westerly reverse flow in the wake. Satellite observations and regional model simulations are used to investigate circulation effects on lee cloud formation during summer. Over the island, the cloud distribution is consistent with orographic-induced vertical m...
