according to coates’s (2004, as cited in zhang, 2010) definition of "conversational dominance" (p.111), it refers to the phenomenon of a speaker dominating others in interaction. specifically, it means how a speaker makes use of certain strategies to get the floor and maintain the floor. thus, the amount of talk is the main measurement for the dominance of the conversation. whether a speaker do...
In this paper, a new model has been introduced for scheduling of a multi-microgrid consisting of low voltage microgrids, distributed generation resources and interruptible loads. In this model, system operator runs its internal market, then by using the results and modeling the upstream market, the internal market is finally cleared based on nodal prices and considering network losses. Fu...
the main objective of this study was to develop an assessment model for the virtual water of irrigation networks using analytical hierarchy process. for this purpose, 14 modern irrigation networks of iran were selected. also, 14 effective factors on the virtual water of these systems were considered as decision criteria. expert choice software was used for ranking the virtual water values of th...
abstract: one of the most visited & important spaces in different countries by tourist are urban areas. the old tehran which major part is located in district 12 is historical showcase of the capital, but, its hiidden cultural attraction is not used as it should be. this thesis occasionally engage in studying the efficacy of correct installation of travel guide boards in welfare & easily acc...
ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...
infiltration rate is one of the most important soil physical parameters and is a basic input data in irrigation and drainage projects. although, a number of theoretical or experimental based equations are presented to describe this phenomenon but the evaluation of some new sciences such as artificial neural networks, for prediction of the phenomenon can be investigated. generally, the infiltrat...
Millions of cubic meters of water run out of reach into rivers annually. Artificial recharge of ground water collection of regional drainage water and re-use of it and simplicity in construction shows Wetland (artificial reservoir) as a sustainable local structure. In planning about irrigation and drainage network of Alborz dam in WEAP medium was modeled. For equitable allocation in project lim...
Clean and sustainable renewable energy technology is going to take responsibility of energy supply in electrical power systems. Using renewable sources improve the environment and reduce dependence on oil and other fossil fuels. In distribution power system, utilizing of wind and solar DGs comprises some advantages; consist of loss and emission reduction, and also improvement of voltage profile...
Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...
water balance components are difficult to measure in short intervals because their measurement is time consuming and costly. therefore, soil-water--plant models can be used for prediction of these components. in this study, to predict grain yield and evaluate water use efficiency, an agro-hydrological model, namely, swap was used. this study covered a 10-years period from 2000-2010. based on th...
