Optimization of composite laminates requires the satisfaction constraints where design ply thicknesses and orientations can only take discrete values prescribed by manufacturers. Heuristics such as particle swarm or genetic algorithms are inefficient in cases because they provide suboptimal solutions when number variables is large. They also computationally expensive handling combinatorial natu...

We study the optimal performance of a three-level quantum refrigerator using trade-off objective function, $\Omega$ which represents compromise between energy benefits and losses thermal device. First, we optimize our by employing two-parameter optimization scheme show that first two-terms in series expansion obtained coefficient (COP) match with those some classical models refrigerator. Then, ...

In the present paper, an approach is proposed for structural topology optimization based on combination of Radial Basis Function (RBF) Level Set Method (LSM) with Isogeometric Analysis (IGA). The corresponding combined algorithm is detailed. First, in this approach, the discrete problem is formulated in Isogeometric Analysis framework. The objective function based on compliance of particular lo...
