A Fast Analytical Algorithm for Very Large Scale Network in Integrated Circuits;

Research purposes: The rational laying track mode should be selected for the line network plan of urban mass transit according to the overall city plan,the situation of land usage and the geographic conditions around the line,for the purposes of disposing the city space resources rationally and saving construction and operation costs.

Discusses the urban traffic line network optimization principle、objective and constraints, presents mathematecal expression for distinct optimum objects function form and corresponding constraints.

The torsion-ring subway can provide a new alignment scheme for solving the problems that the line network density of the proposed urban rail line under planning is too low in the main city area and the line is too long and the investment is large in the overall planning of urban rail.

The basic elements of fishing gear are fishing sythetic fibres, twines and ropes, whose strength performances strongly affect the mechanical and fishing performances of fishing gear and its working duration and production cost.

In this paper, the methods of correct cable arrangement mounting, using, failure and recovery of wire cable for local networking ate studied.

A WMN Adaptive Routing Strategy Based on Interference Model;

Wireless mesh network(WMN) is a new kind of networking technology supporting capabilities such as multi-hop mesh packet routing and forwarding.

WMN (Wireless Mesh Network) is considered to be "The Wireless Version of Internet" , which is a new type of wireless communication network and capable of self-organization and self-cure .
