To evaluate the success of vehicle emissions regulations, trends in both fleet-wide average emissions as well as high-emitter emissions are needed, but it is challenging to capture the full spread of vehicle emission factors (EFs) with chassis dynamometer or tunnel studies, and remote sensing studies cannot evaluate particulate compounds. We developed an alternative method that links real-time ...
Climate change affects the demand for energy consumption, especially for heating and cooling buildings. Using daily mean temperature (Tmean) data, this study analyzed the spatiotemporal changes of the starting date for heating (HS), ending date for heating (HE), length (HL) and heating degree day (HDD) of the heating season in central heating zone of China. Over China's central heating zone, re...
Since 1986 when digital servo was introduced in mass production HDDs, various kinds of control theories have been applied to HDD servo system, and the performances had improved dramatically. A 3.5-inch HDD capacity, which was 251 MB in 1988, has 1,000,000 MB (1 TB) capacity in 2007. The Fast access (high quality motion control), very precise positioning (nanometer scale), and robustness against...
Consider a mass production of HDD arms where hundreds of CNC machines are used to manufacturer the HDD arms. According to an overwhelming number of machines and models of arm, construction of separate control chart for monitoring each HDD arm model by each machine is not feasible. This research proposed a strategy to optimize the SPC management on shop floor. The procedure started from identify...
با فراگیر شدن شبیهسازی نرمافزاری اقلیم منطقهای، این امکان به وجود آمدهاست تا سناریوهای گوناگونی همچون تأثیر پر آبکردن یک دریاچه یا خشککردن آب آن و تأثیر آن بر شرایط اقلیمی منطقه همجوارش، در دنیای مجازی رایانهای شبیهسازی گردد. دریاچه زریوار بهعنوان یکی از دریاچههای مهم شمالغرب کشور گاهاَ در دورههای خشکسالی با تهدید کاهش پهنه آبی مواجه میباشد که این عامل میتواند بهطور مستقیم بر مؤ...
This paper proposed classification models that would be used as a proxy for hard disk drive (HDD) functional test equitant which required approximately more than two weeks to perform the HDD status classification in either “Pass” or “Fail”. These models were constructed by using committee network which consisted of a number of single neural networks. This paper also included the method to solve...
First-line therapies of acute and chronic idiopathic thrombocytopenic purpura (ITP) include intravenous immunoglobulin, IV anti-D and corticosteroids. A short-course high-dose dexamethasone (HDD-SC) therapy has recently been reported to be efficacious in acute ITP. The present study was conducted to assess the efficacy of HDD-SC in children with chronic ITP. Over a period of 10 months, 13 patie...
Nanotized phytochemicals are being explored by researchers for promoting their uptake and effectiveness at lower concentrations. In this study, O-hexadecyl-dextran entrapped berberine chloride nanoparticles (BC-HDD NPs) were prepared, and evaluated for their cytoprotective efficacy in high glucose stressed primary hepatocytes and the results obtained compared with bulk berberine chloride (BBR) ...
Proper data placement schemes based on erasure correcting code are one of the most important components for a highly available data storage system. A new class of Maximum Distance Separable (MDS) array codes is presented for correcting triple storage failures, which is an extension of the double-erasure-correcting EVENODD code and is called the HDD-EOD code. The encoding and decoding procedures...
