In the cooperative system with a large number of users, the base station may select a subset of users to serve in order to maximize the total throughput. The brute-force search for the optimal user set, however, is computationally prohibitive. We propose a clustering algorithm for cooperative communication systems, whose objective is to increase the cellular network throughput and further improve...
Many applications of mobile ad hoc networks (MANETs) adopt hierarchical structure for the scalability and simplify of management. Clustering is the most popular method to impose a hierarchical structure in MANETs. As a newly proposed weighing based clustering algorithm, the weighted clustering algorithm (WCA) has improved performance compared with other previous clustering algorithms. However, the...
Clustering is an important concept for mobile ad hoc networks (MANETs), because clustering makes it possible to guarantee basic levels of system performance, such as throughput, delay and also security issues such as availability, in the presence of both mobility and large number mobile terminals. Many clustering protocols for MANETs have been proposed in the literature. As a newly proposed weighing-based...
This paper is about subdividing of women's breasts based on 3D interactive anthropometric scanning technology. 270 young ladies, aged between 18 to 30 years old, were measured by 3D interactive anthropometric scanner. 11 Characteristic indexes such as breast midriff girth, breast girth items of females' bosom are extracted from 35 variables, which are the decisive factors to determine the tight fashions'...
