Abstract: A wireless personal area network (WPAN) is a personal network, which is a network for interconnecting devices centred on an individual person's workspace, in which the connections are wireless. The WPAN introduced many different standards that depend on WPAN to work. In this paper, I concentrate on two of them, which are Bluetooth and ZigBee. I described their protocol stack, how they work, and at the end of this paper I made a comparison between these two standards in many different features. It is believed that the comparison presented in this paper would benefit application engineers in selecting an appropriate protocol.

Keywords: WPAN, Bluetooth, ZigBee.

Abstract: Schistosomiasis, also known as Bilharziasis, is a parasitic disease of global concern, and is among the neglected tropical diseases. It is caused by the digenetic trematode flukes of the genus Schistosoma and transmitted by fresh water snails of the family Planorbidae. Its clinical manifestation depends on the immunity of the person, the warm burden and the duration of the same worms in the body. African countries suffer greatly from this disease. We have formulated a mathematical model with four compartments, Susceptible-Protected-Infected-Treated, (SPIT), and the corresponding ordinary differential equations in an attempt to investigate the impact of human protection. The disease free equilibrium and endemic equilibrium have been analyzed. The stability of the disease free equilibrium has also been determined. The reproduction number has been determined using the next Generation matrix. Mathematical simulation was carried out. The impact of human protection on the dynamics of the spread of the disease has been analyzed. Our results show that protection of the human being plays a great role in controlling the spread of this disease. It contributes significantly to reduction of infections and the stability of the susceptible population.

Abstract: One of the main problems of machine learning and data mining is to develop a basic model with a few features, to reduce the algorithms involved in classification's computational complexity. In this paper, the collection of features plays an essential role in the classification process in order to minimize computational time, which decreases data size and increases the precision and effectiveness of specific machine learning activities. Due to its superiority to conventional optimization methods, several metaheuristics have been used to resolve FS issues. This is why hybrid metaheuristics help increase the search and convergence rate of the critical algorithms. A modern hybrid selection algorithm combining the genetic algorithm (GA) and the Particle Swarm Optimization (PSO) to enhance search capabilities is developed in this paper. The efficacy of our proposed algorithm is illustrated by a series of simulation phases, using the UCI learning array as a benchmark dataset.
