Support Vector Machine (SVM) is used to classify hyperspectral remote sensing image in this paper. Radial Basis Function (RBF)
which is most widely used
is chosen as the kernel function of SVM. Selection of kernel function parameter is a pivotal factor which influences the performance of SVM. For this reason
Particle Swarm Optimization (PSO) is provided to get a better result. In order to improve the optimization efficiency of kernel function parameter
firstly larger steps of grid search method is used to find the appropriate rang of parameter. Since the PSO tends to be trapped into local optimal solutions
a weight and mutation particle swam optimization algorithm was proposed
in which the weight dynamically changes with a liner rule and the global best particle mutates per iteration to optimize the parameters of RBF-SVM. At last
a 220-bands hyperspectral remote sensing image of AVIRIS is taken as an experiment
which demonstrates that the method this paper proposed is an effective way to search the SVM parameters and is available in improving the performance of SVM classifiers. 2012 IEEE.

Primary mirror' surface figure is affected by supporting structure obviously. Especially for large-aperture telescope
the surface figure is significant because of primary mirror' self-weight. For the requirement of the usage
it's necessary to minimize the surface figure from self-weight by reasonable supporting scheme. The text optimized support point and force of radial support to minimize the surface figure by finite-element software. At the same time
it studied the relationship between support point and counterweight to reduce the weight of support structure. At last
it gave the optimal solution. (2012) Trans Tech Publications.

The effect on the deformation of the primary mirror surface figure of the temperature gradient has been discussed theoretically. And its effect under axis and radial temperature gradient is analyzed when optical axis and support ways of the mirror changed. It has been concluded that the effect on the surface figure of the axis gradient is larger than radial gradient and also found that the deformation is concerned not only with thermal and structural parameter but also directly with the magnitude and direction of the temperature gradient. 2010 IEEE.
