By SQL server database at background for interchanged data. Dividing the knowledge points to different tables and saving them into database. Users could login and browse the...
Dynamic program slice with respect to a variable of interest at some execution position contains only those statements that actually had an influence on this variable. It has been widely used in many software activities, such as debugging, testing and software maintenance. In this paper, we present a dynamic program slicing algorithm based on forward analysis. In this method, dynamic slices are computed...
This paper presents a new and general technique for solving the dynamics of open loop flexible robots. The operator and articulated body algorithms were used to develop new spatially recursive inverse and forward dynamics algorithms for loop flexible robots systems. Compare to O(n3) dynamics algorithms, this algorithm was O(n). In order to show the performance and accuracy of the proposed method,...
As space robots gain more and more importance in space operations, it was becoming imperative to understand their distinctive dynamics. The dynamics model of the space flexible robots is very complex, and the differential equation derived from dynamics was solved difficultly and slowly. In this paper the dynamics of space flexible robots was discussed, and the fast efficient integration method was...
The attitude motion equations of spacecraft multibody system take on nonholonomic constraints without external forces. The dynamic and attitude control of spacecraft multibody system is concerned with nonholonomic constraints system in Hamiltonian approach. The two point boundary value problem of nonlinear dynamic differential equations can be converted into initial value problem by feedback control...
Sensor network consisting of nodes with limited battery power and wireless communications are deployed to collect environmental information. The LEACH protocol is an excellent route protocol for WSN. According to the randomizing and rotation, the cluster heads are chosen to transmit the base station in LEACH protocol. Compared to the LEACH protocol, some enhanced protocols like TEEN and APTEEN achieve...
