Future high performance systems must use energy efficiently to achieve PFLOPS computational speeds and beyond. To address this challenge, we must first understand the power and energy characteristics of high performance computing applications. In this paper, we use a power-performance profiling framework called PowerPack to study the power and energy profiles of the HPC Challenge benchmarks. We...
Background and purpose: Heterotrophic plate count (HPC) is commonly used to assess the general microbiological quality of drinking water. HPC must be less than 500 colonies per milliliter in drinking water. The aim of this study was to compare the heterotrophic bacteria of bottled water and drinking water distribution system and their relationship with water quality parameters. Materials and m...
In this study, the effect of recrystallization of naproxen in the presence of hydroxypropyl cellulose (HPC) on the release rate of drug was investigated. Crystals were generated by the anti-solvent approach using the HPC solution in water as the anti-solvent. The samples were subjected to various physicochemical evaluations such as crystal size, scanning electron microscopy, Fourier tran...
Background and Aim: Recently the use of heterotrophic plate count (HPC) has received much attention as a supplementary indicator of the MPN test in water quality control. The US Environmental Protection Agency (USEPA) has declared 500 cfu/mL as the maximum acceptable level for heterotrophic bacteria in distribution networks. Currently the HPC determination is not among the routine control items...

به منظور تولید ماکارونی با کیفیت مطلوب، معمولا آرد سمولینا که از گندم داروم بدست می آید به کار می رود. از آنجا که سطح زیر کشت گندم داروم در ایران محدود می باشد، لذا تولید آرد سمولینا جهت مصرف در کلیه کارخانجات ماکارونی در کشور امکان پذیر نمی باشد. لذا اکثر کارخانجات ماکارونی از آرد نول که نوعی آرد ضعیف است جهت تهیه ماکارونی استفاده می کنند. در نتیجه ماکارونی حاصل کیفیت مطلوبی نداشته و خصوصا جهت...
محاسبات موازی یکی از موضوعات مورد علاقه جامعه بزرگ علمی است زیرا باعث تسهیل در انجام بسیاری از الگوریتم های وقت گیر در حوزه های مختلف برنامه های کاربردی می شود. در این مقاله، یک پلتفرم جدید برای محاسبات موازی با استفاده از برنامه نویسی mpi و openmp معرفی می کنیم که مبتنی بر مجموعه ای از رایانه های شخصی شبکه شده می باشد. umzhpc یک زیرساخت محاسبات موازی رایگان مبتنی بر لینوکس است که به منظور ایجا...
This paper presents the results obtained with an extension of the HPC-ICTM model for grid computing. The HPC-ICTM is a multi-layered interval tessellation-based model for the categorization of geographic regions for high performance computing. The ICTM model is executed as a Bag-of-Tasks on the OurGrid environment. For each layer, the categorizer process is applied separately, without communica...
Background and purpose: Household drinking water treatment devices are becoming commonplace to improve the quality of drinking water, remove odor, taste, turbidity and color, pathogenic organisms, toxic chemicals, organic matter, and carcinogenic pollutants. This study aimed at investigating the Heterotrophic plate count (HPC) in drinking water and possibility of biofilm formation in household...
