background trihalomethanes (thms) are major group of chlorinated by products, potentially hazardous and carcinogenicity of these compounds was recognized. the purpose of this study was survey on thms concentration in ahvaz drinking water. material and methods a descriptive cross-sectional study was based on 36-week sampling program during the winter, spring and summer of 2011 in water distribut...

Although the compartmentalization of poultry industry components has substantial economic implications, and is therefore a concept with huge significance to poultry industries worldwide, the current requirements for compartment status are generic to all OIE member countries. We examined the consequences for potential outbreaks of highly pathogenic avian influenza in the British poultry industry...

Recently, smart grids have been considered as one of the vital elements in upgrading current power systems to a system with more reliability and efficiency. Distributed generation is necessary for most of these new networks. Indeed, in all cases that DGs are used in distribution systems, protection coordination failures may occur in multiple configurations of smart grids using DGs. In different...

most formidable of all competitors. Japanese companies do not plan or design for their local market but rather for the larger world markets. They realize that they must export to survive. Japan has even developed an expertise in the exporting of entire plants, amortized by the revenues generated in the marketing of products to mature economies. Currently, a Japanese builder is constructing a pe...

considering the network structure is one of the new approaches in studying stochastic pert networks (spn). in this paper, planar networks are studied as a special class of networks. two structural reducible mechanisms titled arc contraction and deletion are developed to convert any planar network to a series-parallel network structure. in series-parallel spn, the completion time distribution fu...

Due to the importance of longest path analysis in networks of queues, we develop an analytical method for computing the steady-state distribution function of longest path in acyclic networks of queues. We assume the network consists of a number of queuing systems and each one has either one or infinite servers. The distribution function of service time is assumed to be exponential or Erlang. Fu...

In practical situations, distribution network loads are the mixtures of residential, industrial, and commercial types. This paper presents a hybrid optimization algorithm for the optimal placement of shunt capacitor banks in radial distribution networks in the presence of different voltage-dependent load models. The algorithm is based on the combination of Genetic Algorithm (GA) and Binary Part...

In order to deal with the huge threat and loss caused by the earthquake, established the evaluation system and model, and the risk zoning map is drawn according to the study of the vulnerability of Xicheng District's streets. According to the spatial coupling relationship between social vulnerability and physical vulnerability, drawn the comprehensive risk zoning map of Shichahai street as a ty...

In this paper we propose an OCR system for Telugu based on the candidate search and elimination technique. The initial candidates for recognition are found by applying a zoning method on input glyphs. We propose cavities as a structural approach suited specifically for Telugu script, where cavity vectors are used to prune the candidates found by zoning. A final template matching stage using con...
