This article shows a comparative study of five algorithms to solve the Capacity Vehicles Routing Problem (CVRP). The first two compared methods use the well-known k-Nearest Neighbor (kNN) algorithm; one of these searches for the Hamiltonian Cycle and then split the route into several subroutes according to the number of vehicles and customers, the other one assigns individual vehicles in order to obtain a route until the capacity of vehicle is exhausted and go back to the depot. The third of them is a Genetic algorithm with an improved cross-over operator to obtain better solutions. The four and five algorithms were Simulated Annealing and Tabu Search, respectively.The set of test instances used to compare the performance of the algorithms corresponds to the well-known set of instances used by the specialized community a proposed by Augerat in 1995. The genetic algorithm proves to find a shorter path and to be closer to the optimal values of the tested dataset, but on the contrary it takes a little longer. On the other hand, Tabu Search shows a similar behavior to Genetic algorithm but results were achieved in shortest time than the Genetic. Read More Read Less

Abstract By introducing the high sensitivity and low offset we have designed hall plates. For generating effective signal processing, we have used a block with a main second-order switch capacitor and filter. Finally, we have presented a new signal processing model with one out of the total f noise values.... By introducing the high sensitivity and low offset we have designed hall plates.

Abstract Electrical current is a diverse electrical quantity. The measurement systems have many direct methods for measurement. We have used an indirect contactless model for measuring the magnetic field by developing a flow through a conductor electrical current. We found that the contactless measurements have high sensitivity and wide frequency with high reliability. They have better linear characteristics due to the... Electrical current is a diverse electrical quantity. The measurement systems have many direct methods for measurement. We have used an indirect contactless model for measuring the magnetic field by developing a flow through a conductor electrical current. We found that the contactless measurements have high sensitivity and wide frequency with high reliability. They have better linear characteristics due to the parallel bridge resistors.
