according to the current challenges toward low water use efficiency in agriculture, paying attention to the role of public participation in order to improve irrigation efficiency and effectiveness with useful methods and tools is essential. hence, approaches such as participatory irrigation management has been proposed and applied. after the primary investigation in this study, experiences of i...

this study aims at empirically furthering awareness of the organization of interaction in efl classes. informed by the methodological framework of conversation analysis, it draws upon a corpus of 52 three-hour naturally-occurring classroom interaction to identify classroom interactional contexts based on the structuring of the pedagogic goals in turn-taking sequences. conversation analytic proc...

IPTV, acronym of Internet Protocol Television, is a system that delivers television services through Internet protocol networks. Therefore, an IPTV system consists of many subsystems including content management, user management, and broadcast management systems. Among the main subsystems, the distribution management system handles purchasing orders from distributors, transcoding original conte...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...

background: drugs play a strategic role as a health commodity. thus, the supply chain management of drugs is an important issue to reducing costs and thereby improving patient health. objective: this study evaluated the status of drug supply chain management and health reform in the pharmaceutical sector of teaching hospitals in ahvaz, iran. methods: this cross-sectional study was carried out i...

spatial and temporal distribution of qualitative factors of groundwaters is important to preserve their quality. so, one of the advanced techniques for distribution of groundwater’s qualitative is geostatistic methods. in this study, 33 active wells were randomly sampled to determine the spatial distribution of nitrate pollution in groundwater of the siakh darengoun region (west of shiraz in fa...

determining the distribution of heavy metals in groundwater is important in developing appropriate management strategies at mine sites. in this paper, the application of artificial intelligence (ai) methods to data analysis,namely artificial neural network (ann), hybrid ann with biogeography-based optimization (ann-bbo), and multi-output adaptive neural fuzzy inference system (manfis) to estima...

In this paper, a distributed method for reactive power management in a distribution system has been presented. The proposed method focuses on the voltage rise where the distribution systems are equipped with a considerable number of photovoltaic units. This paper proposes the alternating direction method of multipliers (ADMMs) approach for solving the optimal voltage control problem in a distri...
