Nowadays, due to the rapid growing popularity of Internet, the global routing system suffers from great scalability problem. Many solutions are proposed to solve the problem, including FIB aggregation, core/edge separation solutions, et al. The limitation of these existing solutions is that they all make the assumption that all addresses in the Internet must be globally visible and these routing information...
Interdomain Multipath Routing, which enables a source AS to use more than one paths for a destination AS, is a promising technique for achieving high bandwidth, high resiliency and fast reaction to failures. However, previous interdomain multipath routing protocols often produce paths which might share bottlenecks, which makes them vulnerable to failure on bottlenecks and therefore inefficient to...
This paper presents a novel approach based on canonical dual theory to discuss global optimization and nonlinear optimal control problems. By introducing a differential flow on the dual feasible space, a set of complete solutions is given regardless of convexity or nonconvexity of the original problem. Meanwhile, applications to a class of linear quadratic optimal control problems are discussed. An...
Let Z be a complete set of Sylow subgroups of a finite group G, that is, for each prime p dividing the order of G, Z contains one and only one Sylow p-subgroup of G. A subgroup H of G is said to be Z-permutable in G if H permutes with every member of Z. In this paper, we prove the pnilpotency of a finite group with assumption that some subgroups of Sylow subgroup are Z-permutable in the normalizers...
In this letter, we propose a distributed cooperation policy selection scheme for energy-constrained ad hoc networks. In particular, we model a correlated equilibrium (CE)-based cooperation policy selection game where the individual utility function is designed from the global energy efficiency perspective. We derive the condition under which the CE is Pareto optimal, and propose a decentralized algorithm...
In order to further ease the unemployment pressure, colleges worked harder on education of student innovation and entrepreneurship. Colleges had tentatively probed in this aspect. However, there were still some problems, such as shortage of teachers. Colleges should further promote the education reform, and actively explore measures on education of student innovation and entrepreneurship. Particularly,...
In order to reduce the searching space of shape context matching method and improve the speed of silhouette matching, a matching method based on partial body silhouette is proposed. In this method body silhouette is divided into segmentations according to the principle of human body composition, and then match the representative silhouettes under the restrictions of limbs silhouette characteristic...
This paper offer a method to obtain UAV's flight parameters at auto-landing period based on the algorithm of camera calibration. According to the geometry features of landing ground to obtain vanishing point, the focal length function is established from the u and v axis scale of the image plane, then the attitude and position of UAV are achieved from the calibration result. Simulation indicates that...
This paper presents a method to determine music-motion correspondence.For specific type of dance and music,system extract low-level features,calculate correspondence ,then select muisc-motion correspondence using genetic algorithms,and get a correspondence satisfing match accuracy and operation speed in the end.The experimental results indicate that system fully express the changes between music and...
Query translation is an important step in cross-language information retrieval (CLIR), therefore the quality of the translations of queries can significantly affect CLIR's retrieval effectiveness. Recent advancement in commercial online machine translation (MT) systems, such as Google Translate, makes it possible for layman Web users to utilize the MT systems for perform cross-language search. To...
Access to academic information is an important work of university digital library construction. Multilingual academic information has high academic value for college teachers, students, and other researchers. This paper discusses the study and design of a multilingual information service platform for university digital library. First, the system's physical architecture is introduced. Second, it describes...
As far as librarians in colleges and universities are concerned, it is significant for them to improve their abilities to provide multilingual information service, which can better meet the increasingly high academic information needs of college students and other researchers. This paper discusses how to improve the capability of multilingual information service for college librarians. Firstly, the...
In this country, there is a great gap on teacher resources allocation in urban and rural. Aiming at solving the problems of lacking qualified teachers resource and teacher post-training in rural, this paper presents network teaching platform to promote coordinated development of urban and rural areas teachers. It sets up a model for promoting coordinated development of urban and rural teachers with...
