is adopted to optimize the multiphase traffic signal timing and phase
sequence at the intersection. The optimization objective is to minimize
the average vehicle delay of every cycle at the intersection. The simulation
results demonstrate that the proposed method can efficiently
reduce the average vehicle delay at the intersection and improve the
traffic capacity of the intersection. In addition, the algorithm is fast and
stable.

RNA secondary structure prediction algorithm based on combinatorial
optimization algorithm and SVMs method, pp.715–719
He, Jingyuan
Chongqing Univ.
A new RNA secondary structure prediction algorithm that can predict
pseudoknots is proposed,it combines the stem-loop combinatorial
optimization algorithm and SVMs(Support Vector Machines,SVMs)
method.The algorithm firstly finds out the optimal stem-loop structure
and suboptimum structures based on dynamic neighbor topology particle
swarm optimization algorithm,and then puts these loops into SVMs.The
output from SVMs can decide whether there exist a pseudoknot.The
experimental results demonstrate the superiority of our algorithm
over the other methods in terms of solution quality and convergence
rates.

Social insect colonies can accomplish complex daily life tasks including
foraging, nesting, preventing enemy and other things in spite of the
simplicity of their individuals, and all the procedures are executed without
any central controller. As a decentralized system, insect colonies
exhibit flexibility and robustness, two features that would be desirable
in an artificial system. Agent and multi-agent are good executor candidates
for stigmergy and swarm intelligence. Stigmergy Agent structure
is presented inspired from animal society, and stigmergy architecture
is extended to extend stigmergy adaptability in more extensive application
systems. Improved bi-partite graph is presented to organization
structure of multi-agent system. Stigmergy Agent and swarm intelligence
based multi-agent system will have promising prospects in many
practical applications.

According to the relation between two elements in different universes, a
fuzzy compatible relation is established as a generalization of rough set
model over two universes. Firstly, new fuzzy approximation operators
are presented basing on a fuzzy set with parameter which is defined
in this article. Meanwhile, several important properties and theorems
are proved as well. Next, by using the calculations of elements in the
fuzzy matrix, a more effective method to obtain the approximate sets is
proposed. Finally, an example is applied to illustrate the significance of
the model.

A Concept Architecture Model with Autonomous Coordination for Flying
Formation, pp.793–796
Liu, Zilin
Logistic Engineering Univ.
Flying formations are an attractive prospect for improved science return
as they provide a natural capability for temporal, spatial and signal separation
with further engineering and economic advantages. As satellite
numbers increase, the traditional ‘‘remote-control’’approach begins
to break down. It is therefore essential to push control into space; to
make spacecraft more autonomous. This article analyses some available
typical autonomous coordination paradigms and then a hybrid autonomous
coordination hierarchy for formations is presented, which is
designed to minimize the traffic of intersatellite links and aid scalability
to larger numbers (hundreds) of small satellites for tasks allocation.

This paper first constructs an model of local swarms with a quadratic
profile. Then study the stability properties of the collective behavior of
the swarm and provide conditions for collective convergence to more
favorable regions of the profile. It is shown that the individuals of the
swarms will aggregate and eventually enter into a bounded hyperball
around the swarm center or objective position. Aimed at removing the
local trap, this paper gives the bound of parameter .

With the development of website, a great many changes took place and
in many fields, people combine our traditional marketing with network
marketing. There are many tools for the website design, and Apache,
PHP (Hypertext Preprocessor) and MySQL has been the most widely
used web development tool for its free and open source. Differences
between PHP, JSP and ASP.NET have been discussed in this dissertation.
The system which will be designed use the website to control
the remote system. Thus, the environmental and demand analysis in
the design, the development model based on PHP, architecture of field
remote system, the development process based on Apache, PHP and
MySQL, details data communication methods and the implement process
of the website are also discussed.

Intervening a group of mobile agents in three dimension, pp.970–975
Li, Xuejing
Beijing Univ. of Tech.
How we intervene the multi-agent systems (MAS) without changing the
local interactions such that the system exhibits the expected collective
behavior is an interesting and important topic. In this paper, we will
investigate the intervention of a class of MAS, where all agents move
in three dimensional Euclidean space. To guide all agents to move
with the same expected direction, we put some information agents (also
called leaders) into the system. Different from [11, ]the heading of each
agent is determined by two coupled angle sequences, which makes the
theoretical analysis quite hard. By estimating some characteristics concerning
the initial states and applying the mathematical induction, we
will provide a quantitative result on the proportion of leaders needed to
guarantee the expected consensus.

According to switching technique, the problem of guaranteed cost control
for uncertain networked switched fuzzy time-delay systems based
on Takagi-Sugeno (T-S) fuzzy model is investigated. Considering the
influence of time-delay under single-packet transmission condition, a
sufficient condition for the existence of the robust guaranteed cost control
law is presented based on single Lyapunov function and multiple
Lyapunov functions method, and the switching law is also designed to
implement the asymptotic stability of fuzzy switched systems. Finally
an illustrative example is used to demonstrate the effectiveness of the
proposed approach.
