با توجه به اینکه در سال¬های اخیر پردازنده¬های چند هسته¬ای و gpu های چند هسته¬ای به عنوان ابزار مقرون به صرفه¬ای برای استفاده در سیستم¬های مختلف مناسب بوده¬اند، امروزه کامپیوتر¬های رو میزی، لپ¬تاپ¬ها و ابر رایانه¬ها و محیط¬های ابری که شامل پردازنده¬های چند هسته¬ای cpu و gpu می¬باشند بسیار رایج هستند. در نتیجه ارائه¬ی سیستم عامل¬هایی برای محاسبات که بر روی cpu و gpu اجرا شوند مورد توجه بسیار زیاد...
noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. a common problem in imaging systems by using cmos or ccd sensors is appearance of the salt and pepper noise. this paper presents cellular automata (ca) framework for noise removal of distorted image by the salt an...
The time consumption in solving computationally heavy problems has always been a concern for computer programmers. Due to simplicity of its implementation, the PSO (Particle Swarm Optimization) is a suitable meta-heuristic algorithm for solving computationally heavy problems. However, despite the simplicity, the algorithm is inefficient for solving real computationally heavy problems but the pr...

for many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. however, an issue that has rarely been studied is the speed of these methods. considering the computer hardware limitations, it is necessary for these methods to run in high speed. one of the methods to increase the processing speed is to use the computer pa...
Background: Hypopharyngeal cancer usually presents with cervical mass, hoarseness, radiated otalgia, and dysphagea in the advanced stages. Radical surgery followed by radiotherapy plays an important role in the treatment of patients with hypopharyngeal cancer. However, there is no general consensus as to which is the best method of reconstruction after surgical resection. The aim of this study ...

A double-GPU code is developed to accelerate WENO schemes. The test problem is a compressible viscous flow. The convective terms are discretized using third- to ninth-order WENO schemes and the viscous terms are discretized by the standard fourth-order central scheme. The code written in CUDA programming language is developed by modifying a single-GPU code. The OpenMP library is used for parall...
