Communication is one of the most important steps in constructing a
robotic system. Such a system has been built based on NI LabVIEW
and compactRIO. In this paper, several methods of communication between
host computer and compactRIO were introduced. By comparison
in the experiment, we found that each method has their unique
benefits and drawbacks. The method of shared variables is the most
convenient; the method of TCP/IP is the most reliable; the method of
UDP has the highest performance. When a system is set up, the most
suitable method of them should be selected according to the user’s
requirement.

Data fusion is an important tool for estimating urban traffic state when
various traffic data are available. In order to get more accurate and
comprehensive traffic state, this paper proposes an improved reliability
revaluated Dempster-Shafer fusion algorithm (RRDSF) and a framework
of real-time traffic state estimation system for fusing multi-source
data, tests on the accuracy by real-world traffic data. The framework of
real-time traffic state estimation system proposed in this paper shows
the feasibility of developing advanced data fusion system for real-time
traffic state estimation. The results report in this paper demonstrate
that the proposed model can fuse data from loop detectors and probe
vehicles to more accurately obtain traffic state estimation than using
either of them alone and encourage us to do further work.

The key characteristic of the game model in this paper is that each
player, before making a choice, informs other players by declaring he
will cooperate or play individually, and the decision to cooperate or not
will be strategic element of player. The optimal trajectory of game in
finite extensive form with the simple coalitional structure is constructed
and the algorithm of value of game for this sort of game is given in this
paper.

Multi Agent system is one of an effective way for resolving task assignment
problem for multi UAVs. The state of agent, especially the
anomalous state, would badly reduce the efficiencies of agents. For
the reason, this paper proposes a dynamic group method based on
health management in multi agent system to improve the agent efficiency
when it performs a mission. The method introduces a decision
Agent also a member Agent dynamic group model and evaluate function
based on health management, which is efficient to coordinate all
the Agents in the system. Simulation results show the validity of the
method.

Abstract―In order to solve the authenticity and integrity problem during
the Transmission of Power Dispatching work tickets, It need encrypt
of the Power Dispatching work tickets. This paper analyzes the main
processes of RSA digital signature algorithm and gives the algorithm
implementation based on the C# language, the algorithm is applied to
an Electric Power Dispatching work ticket Transmission system of an oil
extraction plant, the proven reliability of the algorithm to ensure that the
electronic work tickets of security and non-repudiation.

Particle swarm optimization algorithm in the quantitative analysis of N-
ear Infrared Spectroscopy, pp.4147–4150
Ma, Bibo
China Agricultural Univ.
In this paper, particle swarm optimization (PSO) is used to establish
the model of quantitative analysis of near infrared spectral for cereal’
protein. In this paper, 42 samples are selected for the study. Among
them, 22 samples are used for modeling, and 20 samples are used for
forecasting. The results show that the correlation coefficient of Modeling
is 0.98, standard residual is 0.289; the correlation coefficient of
forecasting is 0.96, standard residual is 0.397. For the method of PSO,
whether it is used for modeling or forecasting, the results are very satisfactory.
So, this method could be used in quantitative analysis of near
infrared spectra.

The research of a programmable and high precision gas pressure generator,
pp.4155–4159
Li, Xuezhe
North China Inst. of Sci. & Tech.
High precision and programmable pressure generating device is needed
in pressure system test, pressure meter calibration and other occasions,
which is used to generate a variety of standard pressure. The
traditional pressure generator using manual pressure has low accuracy,
low efficiency, high price. In the paper, a high precision and full
automatic gas pressure generator is proposed, which applies intelligent
control theory to the pneumatic control system, solves the nonlinear
and uncertainty. The paper also introduces the principle and implementation
of system project. The system can implement PC SPC output
through RS232 communication interface. Experiments show that the
system has advantages of high precision, pressure change smoothly,
small size and flexible operation etc.

In the paper a portable multi-function instrument was developed, which
can quantitatively measure the content of plant components in accordance
with different components of plant leaves have a different absorption
on different NIR spectra. The instrument is mainly composed
of an independent leaves clamp and a multi-function host. Based on
the method of Dual-wavelength the integral type leaves clamp was designed
in the paper, which was composed of dual-LED, spectra filter,
lens, photoelectric receiving device and so on. The design simplified
the optical structure, enhanced the stability of apparatus, and further
