In this paper, we reveal several characteristics of a broadcast communication protocol called DSCF (Directional-Store-Carry-Forward). In recent years, realization of VANETs (Vehicular Ad-hoc Networks) has been demanded for delivering information to vehicles at a low cost. In VANETs, a vehicle may or may not find other vehicles within its radio communication range because of vehicles' mobility, which...
Conclusions In this paper, a phased array antenna (PAA) using crossed dipole antenna elements is examined. A partially driven array technique is used for the array antenna. From the analyzed results, it is shown that the element antenna has conical radiation pattern. Using the element antenna, the beam scanning characteristics of the PAA is investigated. It is found that this array antenna can scan...
A new neural network, double parasols neural network, is proposed here which is similar to a multilayered neural network, but is derived from an interconnected neural network. EBP-EWLS method can be used as a learning algorithm. The proposed network is considered as a generalization of a regressor model for linear systems to nonlinear systems. Using this network, identification and control are examined...
Building a duty roster for staff at an organization can be a very difficult task due to complex and interdependent conditions that a scheduler has to follow. When an automated scheduling system is used to make this process smoother, the users can face other problems. Most automated scheduling systems are designed for producing rosters almost entirely from scratch. This does not address the needs of...
A sophisticated GA/PSO-hybrid algorithm for application to real-world optimization problems was proposed. The configurations of the two consisting methods, GA and PSO, were investigated to enhance the diversity of the former and the fast convergence of the latter simultaneously. The new hybrid algorithm was applied to two test function problems, and the results indicated that the search ability was...
