of the second-order Markov process model was established and set up
in simulink. Composed with the non-twisted lever-arm effect, the result
showed that the acceleration error caused by dynamic twist was large
and need compensated.b

Monitoring System for Forest Fire Based on Wireless Sensor Network,
pp.4245–4248
Zhu, Yingli
Jiangxi Sci. &Tech. Normal Univ.,
The forest is considered as a precious and indispensable nature resource,
but forest fire which can destroy forest resource safety and
threaten human-living environment is considered as one of the severest
disasters. How to monitor and collect information of forest fire at
any time, it is a difficult problem for Forest Fire Prevention Departments
to urgently solve. With the development of sensor technology, MEM-
S and wireless communications, wireless sensor network (WSN) has
wide application in all kinds of fields. In order to prevent forest fire occurrence,
this paper designs a monitoring system for forest fires based
on wireless sensor network and GPRS network. The system gives the
hardware design of wireless sensor nodes and software implementations,
and chooses CC2531 to achieve the process of data acquisition
and transmission, then sends the data through GPRS module to the
remote monitoring center. By means of WSN and GPRS network, the
system accomplishes data acquisition and long distance transmission.

Noisy Blind Source Separation Based on Adaptive Noise Removal,
pp.4255–4257
Tang, Hui
Huazhong Univ. of Sci. & Tech.
A novel natural gradient algorithm with two-step pre-processing is proposed
to solve the noise blind source separation problem. That is bias
removal techniques followed by a de-noise processing based on least
square. Then obtain an algorithm jointly estimating mixing-matrix and
decreasing noise. In the condition of that sources are mutually independent
and added-noise is independent with any source, computer
simulations verify the algorithm is effective and perform better than traditional
algorithm.

A robust and optimal search tactic using multiple looks, pp.4297–4304

We provide an optimal strategy for an autonomous vehicle to detect
a target in a mine hunting operation or in a search & rescue mission.
We assume that the target exhibits mirror symmetry. By mirror symmetry,
we mean that the left hand side of a target is the mirror image of
the right hand side of the same target, and the probability of detection
is maximal when a target is viewed at zero degree while that probability
is minimal when viewed at ninety degrees and is monotonous between
the maximum and the minimum. The optimal strategy consists of
choosing look angles to inspect a target such that the probability of detection
is maximal. We use a novel combination of variational calculus,
symmetry principles, number theory and algebra to determine analytically
the optimal angles. The solutions will help the operators plan for
an effective strategy in a generic search and detection operation. Such
a strategy is robust as most targets of interest possess approximate
mirror symmetry.

Design and Implementation on SOAP-Based Things Management Protocol
for Internet of Things, pp.4305–4308
Dai, Guiping
Beijng Univ. of Tech.
With development of integration requirements for things’ information
based on different connection technology in Internet of Things, higher
level connection-technology-independent protocols are needed to
shield different connection technologies. Things management protocol
is one of these protocols and can be used to exchange things’ information.
Architecture of Internet of Things and necessity of things management
protocol are discussed. A SOAP-based things management
protocol is designed and implemented, including operations supported,
interface definitions for these operations, implementation structure and
processing for this protocol.

Study on A Real-time Optimal Multi-sensor Asynchronous Data Fusion
Algorithm, pp.4362–4367
Qi, Guoqing
Nanjing Univ. of Sci. & Tech.
Oriented on asynchronous data in multi-sensor data fusion system, a
real-time fusion architecture is put forward, which is in unbiased minimum
variance sense. The proposed asynchronous fusion algorithm
can solves the measurements sequentially that does not need to preset
fusion periods for fusion center to synchronize asynchronous data
transmitted from multi sensors. Simulation result has proven the efficiency
of the algorithm, and it also illustrates that the algorithm can
improve the estimation precision obviously when the target is maneuvering
and there is system error in measurement.

The paper presents a wireless sensor network system, including 433
MHz, ZigBee wireless network, data collection node and data concentrator
node. This system is mainly to apply to monitoring winery’s
environment, the principle of which is that data collection node uses
433 MHz wireless network to send data , data concentrator node uses
433 MHz wireless network to receive the data from data collection n-
ode , then sends the data to the sever by ZigBee module through the
processing of MCU. Meanwhile the personal can examine this data to
monitor the change of winery’s environment. The practice proves the
function of WSN system and guarantees the quality of liquor-making.

Recognition of Crude Drugs Based on SVM, pp.4688–4690
Ming, Zhiyuan

Support Vector Machine (SVM) is a machine learning theory based
on statistical learning algorithms, which are lots of unique advantages
on solving the small sample, nonlinear and high dimensional pattern
recognition. This article uses kernel function on support vector machine
to identify propolis in Yunnan. Compared with traditional algorithms, it
can solve the small sample, nonlinear and other issues. The experiments
show the performance is good when using SVM kernel function
on solving the herbs recognition.
