Irrigation water management is crucial for agricultural production and livelihood security in many regions and countries throughout the world. Over the past decades, controversial and conflictladen water-allocation issues among competing municipal, industrial and agricultural interests have raised increasing concerns. Particularly, growing population, varying natural conditions and shrinking wa...

The interbasin water transfer project is an alternative to balance the nonuniform temporal and spatial distribution of water resources and water demands, especially in arid and semi arid regions. A water transfer project can be executed if it is environmentally and economically justified. In this study, the feasibility of two interbasin water transfer projects from Karoon River in the western p...

designing of a pid controller is a very common method for industrial process control and due to its very simple and efficient function; it is used in a wide variety of industrial applications. pid controller to reduce the steady state error and dynamic response of the system is used. pid controller design is an inevitable problem in setting the coefficients need to try a lot of trial and error,...

Being greatly inspired by the natural flowing regulation of water, we propose a new meta-heuristic algorithm — Flowing Water Algorithm (FWA) for solution combinatorial optimization problems (COPs). Since space COPs is multidimensional, complex and has many local extreme values, according to our proposed method, it appears be similar an endless hilly area with mountains, valleys plateaus....

The study of wave and its propagation on the water surface is among significant phenomena in designing quay, marine and water structures. Therefore, in order to design structures which are exposed to direct wave forces, it is necessary to study and simulate water surface height and the wave forces on the structures body in different boundary conditions. In this study, the propagation of static ...

Water-cycle algorithm based on evaporation rate (ErWCA) is a powerful enhanced version of the water-cycle (WCA) metaheuristics algorithm. ErWCA, like other algorithms, may still fall in sub-optimal region and have slow convergence, especially high-dimensional tasks problems. This paper suggests an ErWCA (EErWCA) version, which embeds local escaping operator (LEO) as internal updating process. a...

Grid computing is a process of aggregate the functionality of different geographically resources and provide services to the user. Scheduling is most popular research area in grid computing for achieving high performance. In scheduling, tasks are assigning to resources and maintain the execution. Dependencies constraints are need to preserve for workflow scheduling in grid computing. In this pa...

Abstract To solve the problem of obtaining geoacoustic parameters multi-layer seabed in shallow water, a inversion method based on Bayesian theory is studied this paper. In study, assumed to be horizontal layered elastic medium, and error function established according sound pressure field water layer bayesian theory. The global optimization algorithm used obtain three target wave velocity, den...
