OBJECTIVES To test retrospectively the ability of four freely available rules-based expert systems to predict short- and medium-term virological outcome following an antiretroviral treatment switch in pre-treated HIV-1 patients. METHODS The HIV-1 genotype interpretation systems (GISs) HIVdb, ANRS, Rega and AntiRetroScan were tested for their accuracy in predicting response to highly active an...
\Optimal wire sizing and buuer insertion for low power and a generalized delay model," in Proc. 17 problems are solved in the context of simultaneous device and wire sizing optimization for deep submicron designs. Experiments show that our LR-based optimization algorithm is very eeective and extremely eecient. Up to 16.5% delay reduction is observed when compared with previous work based on the...
M a y / J u n e 1 9 9 8 I E E E S o f t w a r e 3 1 uery and analysis lie at the heart of a geographic information system.1 The ability to analyze geographical patterns and relationships differentiates GISs from computer cartography, computer-aided design, remote sensing, and database management. Computer scientists have researched relational database query languages for more than a decade, but...
Generic Iterative Simulated-Annealing Search (GISS) is a hyper-heuristic algorithm inspired on a Simulated Annealing driven method, on this context its used to explore across the different instance-heuristicstate search space. On this extended abstract we describe the proposed approach, characteristics and others technicals parameters.
در این تحقیق با استفاده از داده های ماهانة حاصل از محاسبة ضرایب مربوط به دما و بارش نقاط شبکه در مختصات ایستگاه تبریز و داده های ماهانة دما و بارش ایستگاه هواشناسی تبریز در یک دورة آماری 53 ساله از سال1951 تا 2003 اثرات دو برابر شدن میزان جو بر دما و بارش به عنوان مهم ترین عناصر اقلیمی شبیه سازی شده است. مدل های هایترگراف و آمبروترمیک ترسیمی برای تبریز مبین تغییرات ماهانة عناصر اقلیمی دما و با...
Climate change is nowadays a major cause of concern in water related fields because it may cause more severe, shortened or prolonged droughts or floods in the future. In this research was tried to the best model of climate change is determined from the climate change models to determining the minimum temperature, maximum temperature and precipitation for the Birjand synoptic station. For this r...
We used the Terrestrial Ecosystem Model (TEM, version 4.0) to estimate net primary production (NPP) in China for contemporary climate and NPP responses to elevated CO2 and climate changes projected by three atmospheric general circulation models (GCMs): Goddard Institute for Space Studies (GISS), Geophysical Fluid Dynamic Laboratory (GFDL) and Oregon State University (OSU). For contemporary cli...
