The development in basic technology and market strategy of solar thermal power techniques is booming rapidly due to the limited fossil resources and severe environmental problems all over the world. In this paper
the design method of heliostats field for the scale of 1MW solar power tower plant with latitude of 40.4N at the design point of the noon of spring equinox is introduced
which uses the multiplication of three efficiencies of cosine
atmospheric transmittance and intercept as the preliminary boundary limit to locate heliostats
while the spacing between heliostats is set not only for less shading and blocking
but also for the availability of installation and maintenance of heliostats. Furthermore
its optical performance tested by the software HFLD
is quite good
which has annual average efficiency of 71.36% and design point efficiency of 80%. 2012 IEEE.

Task allocation is an essential strategy to achieve effective cooperation for swarm robots. Self-organized task allocation strategy is studied and efficient labor division and regulation is realized through local interactions among individual robots based on response threshold model. Local communication mechanism is proposed for the purpose of sharing local sensation information
and the simulation experiments verify that the efficiency of task allocation is improved significantly. 2010 IEEE.

In order to solve the registration problem of different source image existed on aerial image fusion
algorithms based on Particle Swarm Optimization (PSO) are applied as search strategy in this paper
and Alignment Metric (AM) is used as judgment. This study has realized the different source image registration of infrared and visible light with high speed
high accuracy and high reliability. Basically
with little restriction of gray level properties
a new alignment measure is applied
which can efficiently measure the image registration extent and tolerate noise well. Even more
the intelligent optimization algorithm - Particle Swarm Optimization (PSO) is combined to improve the registration precision and rate of infrared and visible light. Experimental results indicate that
the study attains the registration accuracy of pixel level
and every registration time is cut down over 40 percent compared to traditional method. The match algorithm based on AM
solves the registration problem that greater differences between different source images are existed on gray and characteristic. At the same time
the adoption of combining the intelligent optimization algorithms significantly improves the searching efficiency and convergence speed of the algorithms
and the registration result has higher accuracy and stability
which builds up solid foundation for different source image fusion. The method in this paper has a magnificent effect
and is easy for application and very suitable for engineering use. 2010 IEEE.
