Considering path optimization problem on mobile robot, an experimental platform based on NAO robot is set up to build navigation map and get optimal path under unknown environment. Based on simultaneous localization and mapping (SLAM) theory, the sonar sensor of the NAO robot is adopted to detect distances between robot and obstacles and between robot and end landmark. K-means algorithm is used to...
Assembly Line Balancing (ALB) is one of the important problems of production/operations management area. Due to the NP-hard nature of the ALB problem, heuristics are generally used to solve real life problems. This paper presents an approach, based on Particle Swarm Optimization (PSO) algorithm, to effectively address the assembly line balance problem with the complicating factors of parallel workstations...
The intelligent automatic weighing instrument can automatically and immediately calculate and analyze the weight of material in bucket of a loader. A new way to weight the weight of the bucket will be introduced in this paper. The realization plan for the model of the system will be discussed first. And then the hardware and software of the system will be designed. At last, by a large amount of experiments,...
A novel particle swarm optimization (NPSO) algorithm with dynamically changing inertia weight based on fltness and iterations was presented for improving the performance of the Particle Swarm Optimization algorithm. The new algorithm was tested with three benchmark functions. The experimental results show that the swarm can escape from local optimum, and it also can speed up the convergence of particles...
For the purpose of practical application, based on the previous work of full envelope dividing and H-infinity loop-shaping control algorithm, the design of full flight envelope robust control system considering the change of control law was researched. In this paper, the full flight envelope was divided into eight regions based on the temperature and pressure of the engine inlet and H-infinity loop-shapingmethodologywas...
Data processing and node management are key technologies in wireless sensor network (WSN) to reduce the number of transmission of sensor nodes, and hence minimize the overall power consumption, thus to improve the whole performance and emergency response speed of net system, especially in WSN for environment monitoring. This paper provides a method to process data and manage node in WSN for sea water...
This paper presents an improved method of fabric defects inspection based on local entropy. The adaptive threshold was used for judging the defects of different pictures. It is good for reducing the error due to the change of the background and the subjective factor. The Tyler expand is also used to simplify the formula of the local entropy to accelerate the speed of calculation. In addition, noise...
