To solve the seam tracking problem of the mobile welding robot, a prototype of mobile welding robot with welding torch positioned at one side of welding robot is developed. And a new controller based on the dynamics of the mobile welding robot was designed. To make the tracking more quickly and smoothly, the controller combined the algorithm of the integral backstepping and the algorithm of the nerve...
Authentication is a mechanism to establish proof of identities. Traditional password authentication could not provide enough security for the information system when it faces the most modern means of attack. The problem could be solved by taking token authentication, but as a new authentication system, it is difficult connecting with existed authentication systems, especially in the authorized access...
To solve the seam tracking problem of the welding mobile robot, a prototype of mobile welding robot with welding torch positioned at one side of welding robot is developed. Adaptive fuzzy controller and fuzzy-Gaussian neural network (FGNN) controller are designed to complete coordinately controlling of cross-slider and wheels. A specialized learning architecture was used so that membership function...
Mobile devices are in a widespread use today. Restricted by the features of mobile devices, such as mobility, low communication bandwidth, small capacity of memory, limited power and inconvenient interaction, mobile services are required to recommend items adapting to the user need and location. Much existing research on recommendations ignores semantic information of user dynamic historical preferences...
This paper presents a generalized channel preemption model (GCPM) for multiclass traffic in mobile wireless networks. In the proposed model, a mobile call is identified by four parameters - call type, traffic class, channel requirement, and preemption ratio - in which different classes of traffic can have different priority levels. To effectively reduce dropping probability, high-priority handoff...
