in this paper, a connecting rod was modeled and analyzed by finite element method. byusing genetic algorithm (ga) and modified cuckoo optimization algorithm (mcoa), the materialproperties and some geometrical specifications were optimized. cost function was a combination ofweight and stress. the connecting rod was under a load of 21.8 kn which obtained 360o crank angleat 5700 rev/min. the reduc...

In this paper, a comparative study of the path planning problem using evolutionary algorithms, in comparison with classical methods such as A∗ algorithm, is presented for holonomic mobile robot. The configured navigation system, which consists integration sensors sources, map formatting, global and local planners, base controller, aims to enable robot follow shortest smooth delicately. G...

Multihoming and mobility protocols enable computing devices to stay always best connected (ABC) to the Internet. The focus of our study is on handover latency and rehoming time required by such protocols. We used simulations in OMNeT++ to study the performance of the following protocols that support multihoming, mobility or a combination thereof: Mobile IPv6 (MIPv6), Multiple Care-of Address Re...

Full genome data sets are currently being explored on a regular basis to infer phylogenetic trees, but there are often discordances among the trees produced by different genes. An important goal in phylogenomics is to identify which individual gene and species produce the same phylogenetic tree and are thus likely to share the same evolutionary history. On the other hand, it is also essential t...

As with other nature-inspired algorithms, the cuckoo optimization algorithm (COA) produces a population of candidate solutions to find the (near-) optimal solutions to a problem. In this paper, several modifications, including a dynamic mutation operator, are proposed for this algorithm. Design of experiments is employed to determine factors controlling the value of parameters and the target le...

In recent years, various heuristic optimization methods have been developed. Many of these methods are inspired by swarm behaviors in nature, such as particle swarm optimization (PSO), firefly algorithm (FA) and cuckoo optimization algorithm (COA). Recently introduced COA, has proven its excellent capabilities, such as faster convergence and better global minimum achievement. In this paper a ne...

It however relies on a single 802.11 network interface card only, which fails to support simultaneous access of 802.11 and non-802.11 services. As such, mul...
