Approaches in WSN technology has determined by opportunity of tiny and inexpensive sensor nodes with adequacy sensing multiple kinds information processing wireless communication. Network lifetime energy efficiency are major indexes WSN. Several clustering techniques intended to extend the network but whereas there is an issue incompetent Cluster Head (CH) election. To overcome this issue, Inte...

‎the water wave generation by wave paddle and a freely falling rigid body are examined by using an incompressible smoothed particle hydrodynamics (isph)‎. ‎in the current isph method‎, ‎the pressure was evaluated by solving pressure poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure poisson equation contains both of divergence free ve...

this study is focused on developing an integrated optimization-simulation based genetic algorithm model (iosga) to develop the operational policies for a multi-purpose reservoir system. the objective function of the optimization model is considered to be a linear function of reliability (rel), resiliency (res), and vulnerability (vul) of the river-reservoir system. genetic algorithm (ga) is emp...

Energy efficiency is considered the major design issue in wireless sensor networks (WSN), which can be addressed using clustering and routing techniques. They are treated as Non-deterministic Polynomial (NP)-hard optimization problems solved metaheuristic algorithms to identify optimal or near-optimal solutions. With this motivation, paper develops a hybridization of cluster-based (HMBCR) techn...

Maintenance scheduling of generating units is considered one of the vital power system problem for providing power in a reliable and economic way. In order to improve the overall availability of the generating units, chances of capacity shortage is to be reduced by performing preventive maintenance at regular intervals. In this paper, Hybrid integer coded Water Wave Optimization (HWWO) Algorith...

In the structural optimization problem, the aim is to decrease the amount of structural costs and weight, but the safety of platform should not violate the individual limits enforced by offshore codes. The outer diameter and thickness of members are two important variables in the optimization process and their final dimensions should be obtained according to the optimization algorithms such as ...

This paper presents a method for ultrasonic characterization of porous silicon in which a genetic algorithm based optimization is used to solve the inverse problem. A one dimensional model describing wave propagation through a water immersed sample is used in order to compute transmission spectra. Then, a water immersion wide bandwidth measurement is performed using insertion/substitutionmethod...

for a uniform distribution of water, decrease in water waste and decrease in erosion of soil, it is important that a land be prepared with proper slopes along its length as well as width. the aim of leveling is to create appropriate slopes for irrigation and drainage on the lands that were not already properly levelled and of the same time creating the level surface with a minimum transport of ...
