The use of graphics processing units (GPUs) in simulation applications offers a significant speed gain as compared to computations on central processing units (CPUs). Many simulation methods require a large number of independent random variables generated at each step. We present two approaches for implementation of random number generators (RNGs) on a GPU. In the one-RNG-per-thread approach, o...
Cardiorespiratory fitness has been shown to protect and enhance cognitive and brain functions, but little is known about the cortical mechanisms that underlie these changes in older adults. In this study, functional near infrared spectroscopy (fNIRS) was used to investigate variations in oxyhemoglobin [HbO2] and in deoxyhemoglobin [HHb] in the dorsolateral prefrontal cortex (DLPFC) during the p...
Energy crisis in particular, electricity the isolated rural areas of Indonesia is a very crucial issue that needs to be resolve through electrification . Compared other options, pico hydro cross-flow turbine (CFT) better option provides electrical power for areas. Studies improve CFT performance can undertaken analytically, numerically, experimentally, or combination those methods. However, dev...
The accuracy of stochastic (Monte Carlo) simulations is critically dependent on the quality of their random number generator (RNG). Recently, such simulations are increasingly implemented in a parallel form on field-programmable gate arrays (FPGAs) for higher performance. Fast, high-quality RNGs with periods long enough for extended simulation (e.g., the Mersenne Twister) have been well-proven ...
Two collections of oligonucleotides have been designed for preparing pangenomic human and mouse microarrays. A total of 148,993 and 121,703 oligonucleotides were designed against human and mouse transcripts. Quality scores were created in order to select 25,342 human and 24,109 mouse oligonucleotides. They correspond to: (i) a BLAST-specificity score; (ii) the number of expressed sequence tags ...
در این پژوهش شبیه سازی عددی توزیع و پخش ذرات در داخل یک ساختمان سه بعدی و با استفاده از نرم افزار فلوئنت، مورد مطالعه قرار گرفته است. با به کارگیری دیدگاه اویلری برای فاز سیال و اعمال روش حجم محدود در گسسته سازی معادلات حاکم، معادلات بقای جرم و مومنتم حل شده است. حرکت ذرات معلق با استفاده از دیدگاه لاگرانژی و با در نظر گرفتن نیروهای درگ، گرانش، لیفت و براونی ( و نیروی ترموفورسیس برای گازهای co ...
The scientific literature is filled with examples of bad random number generators (RNGs), and a bad RNG can completely ruin a researcher’s analysis. See Coddington (1994, 1996) for examples and discussion from the field of physics. Examples from economics are difficult to find, in part, because many economists do not bother to test the RNGs that they use in their applied work. This may be due t...
Flow separation at water intake is the main cause of head loss and flow discharge reduction. 
As a result, study of shape and size of separation is very essential when designing an optimum water intake. Water intake is normally built with a 90 degree angle to the main channel flow direction. However, the flow structure in this type of water intake consists of large separation size along wit...
