this study presents an overview of the different strategies that persian learners of english employ to deal with initial clusters. while vowel epenthesis appears to be the most widespread repair strategy to conform such clusters to persian phonotactics, the location of the epenthetic vowel varies. in this paper, we investigate two approaches that seek to explain the epenthetic site. the first o...

parallel computing is a topic of interest for a broad scientific community since it facilitates many time-consuming algorithms in different application domains.in this paper, we introduce a novel platform for parallel computing by using mpi and openmp programming languages based on set of networked pcs. umzhpc is a free linux-based parallel computing infrastructure that has been developed to cr...

The cloud computing is considered as a computational model which provides the uses requests with resources upon any demand and needs.The need for planning the scheduling of the user's jobs has emerged as an important challenge in the field of cloud computing. It is mainly due to several reasons, including ever-increasing advancements of information technology and an increase of applications and...

Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. Mobile Computing is a Generic word that introduces using of movable, handheld devices with wireless communication, for processing data. Mobile Computing focused on providing access to data, information, services and communications anywhere an...

Synthesizing realistic images involves computing high-dimensional light-transport integrals. In practice, these integrals are numerically estimated via Monte Carlo integration. The error of this estimation manifests itself as conspicuous aliasing or noise. To ameliorate such artifacts and improve image fidelity, we propose a perception-oriented framework to optimize the rendering. We leverage m...

nowadays, wireless sensor network has been of interest to investigators and the greatest challenge in this part is the limited energy of sensors. sensors usually are in the harsh environments and transit in these environments is hard and impossible and moreover the nodes use non- replaceable batteries. because of this, saving energy is very important. in this paper we tried to decrease hard and...
