It started at about 7:45 am in the school courtyard.Our physical education teacher stood on the concrete stage where our principal would give her talk at school assemblies.All children and teachers would follow the teacher’s lead to do the eight-segment national calisthenics in unison with loud music from loudspeakers affixed on trees around the courtyard.When I visited the school last May,I saw that students still performed the routine faithfully but with a different set of展开更多

In this paper we propose a hybrid method which is a combination of traffic classification by the help of colored pheromones and helping ants method in the intermediate nodes. This combination increases the convergence speed and decreases the delay and Jitter in the network. Also we compare the obtained results with two known routing algorithms that are based on the ant colony.展开更多

It is necessary to apply a dynamic and systematic approach to effectively man- age the complex agri-eco production and green processing systems. Indeed, farming systems approach for appropriate technology development and simulation modeling is a result of adopting the system thinking by the agricultural research community （Norman et al. 1995）.展开更多

In this paper, we argue that flexible helping hosts (referred to as Message Cabs (MCabs)), with deployment and routes that response to the changes in the traffic demand of the network, may overcome this drawback and reduce the message delay in the networks. To demonstrate the effectiveness of this observation, we propose a new helping host scheme namely the Message Cab (MCab) scheme for partition restoration in MANETs, and validate the performance through simulations.展开更多
