Hydraulic Pump sumps are designed to provide a swirl free flow to the pump. The degree of swirl is measured in physical model tests using a swirl meter and a quantity known as swirl angle is generally measured. The present paper presents a novel method to compute the bulk swirl angle using the local velocity field obtained from computational fluid dynamics data. The basis for the present method...

This is a cross-sectional, multicenter, controlled study aiming to evaluate changes of actual dietary nutrient intake in 94 stable hemodialysis patients in respect to 52 normal subjects and guideline recommendations, and to assess the prevalence of signs of malnutrition. Energy and nutrients intake assessment was obtained by a three-day period food recall. Anthropometric and biochemical paramet...

Computational Fluid Dynamics is used to assess the thermal (heat transfer) performances of an automobile engine considering different grille opening and closing degrees. For this purpose entire vehicle modelled three fundamental aspects are examined, namely, open area air intake grille, position upper lower grilles their shape. The results show that have some influence also on aerodynamic chara...

in this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. experiments were carried out by planar imaging and particle image velocimetry (piv) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and fue...

Aim Fruit category classification is important in factory packing and transportation, price prediction, dietary intake, so forth. Methods This study proposed a novel artificial intelligence system to classify fruit categories. First, 2D fractional Fourier entropy with rotation angle vector grid was used extract features from images. Afterwards, five-layer stacked sparse autoencoder as the class...

introduction: the relative costs of generating energy vary considerably depending on location. since hospital managers confront serious financial problems, they need to look for ways to use energy more efficiently. this study aimed to study the rate of energy use (water, gas and electricity) in a number of hospitals in isfahan from 1378 to 1382 and to compare the results with the available stan...

conclusions due to seasonal variations in fruit and vegetable dietary intakes, the interventional and case-control studies should consider seasonality. educational and price controlling programs may control such observed seasonality in the intake of fruit and vegetables. results the highest consumption of vegetables was seen in summer (289 ± 3.4 g/day) while the lowest was in winter (224 ± 3.2 ...

one of the causes of perturbation at vertical intakes is the happening of vortices with an air core. the vortices with an air core occur whenever the submergence of the intake is less than a critical value. anti-vortex devices and specially plates are used to avoid the negative effects of the air-core vortices. if plates are used, then the geometry of them should be studied experimentally. acco...

background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...
