Tensions over water resources in upland areas of northern Thailand are often attributed to reductions in water supply caused by forest clearing. This article argues that the hydrological evidence for such reductions in supply is very weak and that, rather, the key hydrological issue in upland catchments is a significant increase in water demand, especially during the dry season. The arguments a...

This paper determines the application of a model predictive control (MPC) technique to improve the behavior of the water network supply system, to maintain stable operation of the water flow rate, and reduce the operational cost by manipulating the pump speed. The MPC algorithm is one of the most common automatic control system that has got a wide spread application in process industry. MPC is ...

background: intestinal parasitic infections have a worldwide distribution. high prevalence of intestinal parasitic infections in individuals with low socioeconomic status and environmental conditions was found. no study has ever been conducted on the prevalence of these infections in jiroft. therefore, in this study prevalence of intestinal parasitic infections was evaluated in jiroft, kerman p...

One of the most strategic and the most significant decisions in supply chain management is reconfiguration of the structure and design of the supply chain network. In this paper, a closed loop supply chain network design model is presented to select the best tactical and strategic decision levels simultaneously considering the appropriate transportation mode in activated links. The strategic de...

In recent years, the water supply task of urban pipe network is more and heavy, leakage accidents often occur, among which most serious accident burst accident. To solve this problem, study uses WaterGEMS software to establish topological structure network, adopts model computer technology carry out dynamic analysis on golden section method predict caused by state.
