Authors: Zhang Chun Yang , Li Jun Fu , Xu Qian
Published: February 2014

Variety of routing approaches are employed by global routers in the VLSI circuit designs. Rip-up and reroute, as a conveniently implemented method, is widely used in most of modern global routers. Maze algorithm is always performed iteratively as the final technique to eliminate overflow. Maze algorithm and its ramifications can obtain an optimum solution. However, it will cost much CPU time if being used impertinently. In this work, we present a global router called Bottom-Up Router (BU-Router), with an optimized maze algorithm, which is based on multi-source multi-sink maze. BU-Router processes not the nets but the segments of nets in a sequence ordered by the length. In the progress, segments will be fixed on the global route graph edge, when the edge is saturated, which is as the basis, also known as bottom. Then the edge will be set as a blockage, which wont accept path goes through it any more. This means the edge will push the possible congestion in the future. Besides this, BU-Router optimized cost function in two ways: make the function adaptive and congestion center avoidable. Additionally, a specific optimized maze algorithm is proposed for routing a long distance segment so as to reduce the run-time.

Published: February 2014

The smart grid that the next-generation electric power system is studied intensively as a promising solution for energy crisis. One important feature of the smart grid is the integration of high-speed, reliable and secure data communication networks to manage the complex power systems effectively and intelligently. The goal of smart grid is to achieve the security of operation, economic efficient and environmental friendly. To achieve this goal, we proposed a fine-grained access control model for smart grid. In order to improve the security of smart grid, an access-trust-degree algorithm is proposed to evaluate the reliability of the user who want to access to the smart grid.

Authors: Lin Zi Zhi , Shu Si Hui , Ding Yun
Published: February 2014

Association rule mining is one of the most important techniques of data mining. Algorithms based on matrix are efficient due to only scanning the transaction database for one time. In this paper, an algorithm of association rule mining based on the compression matrix is given. It mainly compresses the transaction matrix by integrating various strategies and fleetly finds frequent itemsets. The new algorithm optimizes the known algorithms of mining association rule based on matrix given by some researchers in recent years, which greatly reduces the temporal and spatial complexity, and highly promotes the efficiency of finding frequent itemsets.

Design a Trellis-Based Receiver to Combat CCI in EDGE Network
Authors: Linh Tran Thi Thuc , Bac Dang Hoai
Published: February 2014

Like in GSM network the co-channel interference (CCI) is popular in EDGE network due to the problem of reusing frequency in distant cells. Although the distance between cells using the same frequencies is quite far but CCI still causes significant effect to the channel capacity rather than noise. In fact, many solutions were introduced to reduce the CCI accompanied with improving network capacity such as using MIMO scheme or SAIC scheme. The paper describes a novel receiver model which provides better performance than that of a SAIC system as well as smaller size and cost than a MIMO system. This proposed receiver uses two co-located antennas with difference polarizations to improve the total performance of the system. In addition, this receiver can be applied effectively in high-modulation scheme, for instant, 8-PSK modulation format in an EDGE network and /or in presence of more than one dominant interference.

Steel-concrete castellated composite beams are a new form, also widely used in bridges and buildings. But the research for the vibration characteristics of the composite beams is less. In this paper, by using the principle of the finite element, it mainly analyzes the influence of some related elements, such as the steel beam web part of the opening location, the size, the location and so on, on composite beam vibration frequency to lay the foundation of further study on the dynamic characteristics of the castellated composite beam.
New Delay-Dependent Stability Criteria for Recurrent Neural Networks with Time-Varying Delays
Authors: Ren Ze Rong , Xie Xiang Jun
Published: February 2014

This paper is concerned with the problem of delay-dependent asymptotic stability criterion for recurrent neural networks with time-varying delays. A new Lyapunov functional is introduced by considering the information of neuron activation functions adequately. By using the improved delay-partitioning method and reciprocally convex approach, a less conservative stability criterion is obtained in terms of linear matrix inequalities (LMIs). A numerical example is finally given to illustrate the effectiveness of the derived method.
Extending Linear Temporal Logic with Clocks to Object-Z
Authors: Wen Zhi Cheng , Chen Zhi Gang
Published: February 2014

Object-Z, an extension to formal specification language Z, is good for describing large scale Object-Oriented software specification. While Object-Z has found application in a number of areas, its utility is limited by its inability to specify continuous variables and real-time constraints. Linear temporal logic can describe real-time system, but it can not deal with time variables well and also can not describe formal specification modularly. This paper extends linear temporal logic with clocks (LTLC) and presents an approach to adding linear temporal logic with clocks to Object-Z. Extended Object-Z with LTLC, a modular formal specification language, is a minimum extension of the syntax and semantics of Object-Z. The main advantage of this extension lies in that it is convenient to describe and verify the complex real-time software specification.
