irrigation management transfer to farmers is one of the important and necessary issues for irrigation planners globally. irrigation management transfer or participatory irrigation management by water users’ associations (wua) is a widespread strategy in the world and a good way to remove the country's irrigation and drainage systems problems. the main objective of this research was respons...

the objective of this study was to develop a cost minimizing pattern for cube sugar and sugar transportation from production centers to refinement and storage centers and finally to distribution and consumption  centers in  fars province. producing centers are marvdasht (27.3%), eghlid (27.9%), fasa (11.3%), kavar (7.3%) and mamasani (20.2%). some of the province’s cube sugar and sugar is provi...

strip tearing during cold rolling process has always been considered among the main concerns for steel companies. several works have been done so far regarding the examination of the issue. in this paper, experimental data from cold rolling tandem mill is used for detecting strip tearing. sensors are placed across the cold rolling tandem mill. they receive information on parameters (such as ang...

the computer industry has defined the ieee 802.16 family of standards that will enable mobile devices to access a broadband network as an alternative to digital subscriber line technology. as the mobile devices join and leave a network, security measures must be taken to ensure the safety of the network against unauthorized usage by encryption and group key management. ieee 802.16e uses multica...

In this paper, an efficient and comprehensive hybrid intelligent technique for the optimal placement of phasor measurement units (PMUs) is proposed to minimize the number of PMU installation subjected to full network observability. Three main purposes of PMUs output synchronous measurements are monitoring, control, and protection of power system. We have combined Binary Imperialistic Competitio...

Probabilistic approach of traffic assignment has been primarily developed to provide a more realistic and flexible theoretical framework to represent traveler’s route choice behavior in a transportation network. The problem of path overlapping in network modelling has been one of the main issues to be tackled. Due to its flexible covariance structure, probit model can adequately address the pro...

This study was performed to radiographically examine the prevalence of aspiration sites and to evaluate their anatomical correlation with the bronchial patterns. Ten healthy beagle dogs were repeatedly radiographed, at weekly intervals, in the left and right lateral, ventrodorsal (VD) and dorsoventral (DV) positions. Three milliliters of iohexol distilled with same volume of saline was infused ...

Numerous algorithms have been proposed to solve the shortest-pathproblem; many of them consider a single-mode network and crispcosts. Other attempts have addressed the problem of fuzzy costs ina single-mode network, the so-called fuzzy shortest-path problem(FSPP). The main contribution of the present work is to solve theoptimum path problem in a multimodal transportation network, inwhich the co...
