Performance of Chamomile (Matricaria chamomilla L.) was evaluated on twelve transplanting dates that were arranged at 30 days interval; during 2013-2014 on experimental field of Wondo Genet agricultural research center; using RCBD design with three replications. Transplanting time exerted a very highly significant (p<0.0001) influence on plant height, flower yield and essential oil yield; essen...

recently, time reversal (tr) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (mi) applications. one of the applications turning into a great interest is through-wall microwave imaging (twmi). in this paper, tr method is applied to detect and localize a target obscured by a brick wall using a numerically generated data. regarding this, i...

Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...

⎯The convergence of genetic algorithm is mainly determined by its core operation crossover operation. When the objective function is a multiple hump function, traditional genetic algorithms are easily trapped into local optimum, which is called premature convergence. In this paper, we propose a new genetic algorithm with improved arithmetic crossover operation based on gradient method. This cro...

This paper summarizes the most important advances of the used crane control technology in perspective of unmanned operation of container cranes. Unmanned operation with remote control support today is available for almost all types of new/existing rail mounted container cranes. Storage capacity is the limitation for most terminals today; unmanned operation offers optimum stacking density and pe...

in this paper, we focus on a continuously deteriorating critical equipment which its failure cannot be measured by cost criterion. for these types of systems like military systems, nuclear systems, etc it is extremely important to avoid failure during the actual operation of the system. in this paper we propose an approach which constrains failure probability to a pre-specified value. this valu...
