A cultural algorithm, rooting from simulation of evolution of human being society, provides a new computable framework of evolution algorithms. A novel cultural algorithm based on particleswarmoptimization (PSO) algorithm was proposed in this paper. With the advent of the grid, task scheduling in heterogeneous environments becomes more and more important. After analyzing the model of grid scheduling problem, the CPSO algorithm was presented to solve the resource scheduling problem in grid computing. The optimal objective is to minimize the total completing time. The improved algorithm can keep all the advantages of the standard PSO, such as implementation simplicity, low computational burden, and few control parameters, etc. Simulation results demonstrate that it can be superior to the regular PSO. We also tested the CPSO algorithm with the Max-Min method to show the algorithm’s efficiency.

Hausa sign language (HSL) is the main communication medium among deaf-mute Hausas in northern Nigeria. HSL is so unique that a deaf-mute individual from other part of the country can rarely understand it. HSL includes static and dynamic hand gesture recognitions. In this paper we present an intelligent recognition of static, manual and non-manual HSL using an enhanced Fourier descriptor. A Red Green Blue (RGB) digital camera was used for image acquisition and Fourier descriptor was used for features extraction. The features extracted chosen manually and fed into artificial neural network (ANN) which was used for classification. Thereafter particle swarm optimization algorithm (PSO) was used to optimize the features based on their fitness in order to obtain high recognition accuracy. The optimized features selected gave a higher recognition accuracy of 90.5% compared to the manually selected features that gave 74.8% accuracy. High average recognition accuracy was achieved;hence, intelligent recognition of HSL was successful.

Cancer is related to a class of diseases characterized by out-of-control cell growth. Chemotherapy as one of the most conventional methods of cancer treatment aims to kill cancer cells, but this treatment will damage healthy cells as well. In this regard, mathematical modeling and optimization of drug scheduling can be effective in improving the drug injection timing, with minimum side effects. In this paper a phase specific cancer tumor model have been considered to describe the effect of drug on different cell populations, plasma drug concentration and toxic side effects. A feedback controller of PID type is developed in order to maintain a predefined drug concentration level. This level or controller's input signal have been determined in such a way as to limit the plasma drug concentration which also limits the toxic side effects. In addition, the particleswarmoptimization (PSO) algorithm is employed to optimize the PID controller parameters. Simulation results show that the drug which is injected using this algorithm leads to a reduced number of cancer cells at the end of treatment while the normal cells population, despite the toxicity of the drug, remains almost in the acceptable range.

In order to estimate the coherent source, a modified multiple signal classification (MUSIC) algorithm is introduced. And a novel arrangement method for the non-uniform linear array by particleswarmoptimization (PSO) algorithm is proposed. This method needs merely a signal source whose direction-of-arrival (DOA) has been exactly known. The proposed method has a simple processing and a strong stabilization. It could be applied to optimized arbitrary array configuration. The simulation verifies that the performance of DOA estimation is improved effectively, which has proved the validity of the proposed method.

Grid computing is actually the next generation of distributed systems. Its objective is to create a powerful, large and autonomous virtual computer. This computer is created through assembling countless heterogeneous resources with the aim of sharing them. Scheduling is one of the most important and challenging issue of such systems. An accurate and efficient schedule is required to increase the grid efficiency. Grid resources belong to different management domains;each one applies different management policies. This paper proposed a new heuristic approach based on particle swarm optimization algorithm in order to scheduling the jobs in gird environment. The proposed algorithm would create an optimal scheduler to complete the jobs in the minimum flowtime and makespan.

The loop-closing operation is usually used to transfer power supply without power interruption in the distribution network, but the excessive current induced by loop-closing will endanger the safety and stability of the distribution network. This paper presents a multi-objective optimal control method of loop-closing in distribution network. Firstly, the mathematical optimization model of loop-closing optimal regulation is established, which not only ensures the security of loop-closing operation, but also takes into account the stability and voltage quality of distribution network operation. Then, Pareto entropy-based multi-objective particleswarmoptimization (PE-MOPSO) algorithm is proposed to solve the optimization problem. Finally, an actual example is simulated based on MATLAB platform. The simulation results show that the optimization model is correct, and PE-MOPSO algorithm has good diversity and convergence, and can give a reasonable control scheme.

With the evolution of AI technology, several emerging applications (such as computational offload and image recognition) place higher demands on the quantity and quality of data transmitted by wireless sensor networks (WSNs). Existing routing algorithms typically choose the transmission path with fewer hops and shorter distance. For energy-constrained WSN, this will lead to rapid energy loss and loss of several nodes, which will shorten the network life cycle. In this paper, a WSN routing method based on the ant colony optimizationalgorithm and the particle swarm optimization algorithm is proposed to deal with the above-mentioned problems. By establishing the multidimensional pheromone model of node distance, hop number and energy, the nodes can dynamically adjust the routing according to the residual energy in the data transmission process, so as to ensure the balanced decrease of node energy and prolong the lifetime of the WSN network. In order to improve the convergence rate of ant colony algorithm and reduce the energy consumption caused by reconstruction, particleswarmoptimization is applied;the fitness function of particle swarm optimization algorithm is improved to ensure that the path can quickly find the optimal solution of the path when multiple self-repairs or repair failures occur. The simulation shows that this method can improve the network lifetime by 33% by ensuring high transmission effectiveness.

High-precision short-term wind generation prediction results are conducive to making a scientific generation plan and improving the wind power absorption capacity of the power grids. Based on the analysis of the relationship between the numerical weather prediction and wind power, this paper proposes a short-term wind generation combined forecast model considering meteorological similarity to improve the prediction accuracy of short-term wind power. In this method, the meteorological similarity day model, the extreme gradient boosting algorithm and the back propagation neural network algorithm are selected for achieving the short-term wind power prediction. Then, the particle swarm optimization algorithm is applied to determine the weight of each single forecasting model. Finally, the prediction results are obtained through the combination of the single model prediction results. With the realistic wind power data collected from a wind farm in Xinjiang province, the short-term wind forecasting task is achieved by the proposed method. The simulation results illustrate that the combined model proposed in this paper can effectively improve the forecasting performance of the benchmark models.
