In this article 4 we introduce a blockage-detection method, which manages to detect a large set of blockage positions in pawn endgames, with practically no additional overhead. By examining different elements of the pawn structure, the method checks whether the Pawns form a blockage which prevents the King from penetrating into the opponent’s camp. It then checks several criteria to find out wh...

one of the barriers during whey filtration using uf membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. in this work, the uf membranes were prepared using polysufone (psf), dimethyl formamide (dmf), 1 wt.% poly vinyl pyrrolidone (pvp) and different concentrations of licl via phase inversion induced by immersion precipitation. the prepared membranes were charact...

Previous research has shown that local scour at bridge piers is severely increased by the accumulation of woody debris around piers. However, due to unavailability accurate information regarding characteristics formed jams, shape and dimensions accumulations tested in previous laboratory experiments have had be assumed. This article provides an assessment debris-induced based on recently availa...

Background: Tubal pathology ranks among the most frequent causes of subfertility, next to ovulatory disorders and sperm defects .There fore , assessment of tubal patency is a fundamental part of infertility workup. Investigation for tubal disease can be divided into radiological tests: hysterosalpingography (HSG) , selective salpingography and hystero-contrast-sonography (HyCoSy) , microbiologi...

The main focus of this study is to apply a computational tool for the flow analysis of the turbine engine that has been tested with ice crystal ingestion in the Propulsion Systems Laboratory (PSL) at NASA Glenn Research Center. The PSL has been used to test a highly instrumented Honeywell ALF502R-5A (LF11) turbofan engine at simulated altitude operating conditions. Test data analysis with an en...

Abstract Fast engineering wake models are the backbone of wind farm annual energy production (AEP) estimators, whereas addition induction zone in existing tools is a more recent response to rising concerns over blockage associated losses. Here, “blockage” describes combined fields all turbines inside farm. Unlike term might suggest, not only reduces flow speeds, but also increases them; for ins...

Large wood increases the morphological and hydraulic complexity of rivers, yet it may block modify flood discharge capacity structures. To assess related risk, blockage probability estimation for structures such as reservoir spillways is needed. This work presents unstudied parameters large with a reservoir-type approach flow, where inflow velocity has negligible magnitude. Experiments were con...

The efficiency of tidal-stream turbines in a large array depends on the balance between negative effects turbine-wake interactions and positive bypass-flow acceleration due to local blockage, both which are functions layout turbines. Here we investigate hydrodynamics an infinitely with aligned or staggered layouts for range streamwise lateral turbine spacing. First, present theoretical analysis...
