Given an m-sequence, the main factor influencing the least period of the Generalized Self-Shrinking （GSS） sequence is the selection of the linear combining vector G. Based on the calculation of the minimal polynomial ofL GSS sequences and the comparison of their degrees, an algorithm for selecting the linear combining vector G is presented, which is simple to understand, to implement and to prove. By using this method, much more than 2^L-l linear combining vectors G of the desired properties will be resulted. Thus in the practical application the linear combining vector G can be chosen with great arbitrariness. Additionally, this algorithm can be extended to any finite field easily.

The piecewise planar model(PPM) is an effective means of approximating a complex scene by using planar patches to give a complete interpretation of the spatial points reconstructed from projected 2D *** traditional piecewise planar stereo methods suffer from either a very restricted number of directions for plane detection or heavy reliance on the segmentation accuracy of superpixels. To address these issues, we propose a new multi-view piecewise planar stereo method in this paper. Our method formulates the problem of complete scene reconstruction as a multi-level energy minimization problem. To detect planes along principal directions,a novel energy formulation with pair-wise potentials is used to assign an optimal plane for each superpixel in an iterative manner, where reliable scene priors and geometric constraints are incorporated to enhance the modeling efficacy and inference efficiency. To detect non-principal-direction planes, we adopt a multi-direction plane sweeping with a restricted search space method to generate reliable candidate planes. To handle the multi-surface straddling problem of a single superpixel, a superpixel sub-segmenting scheme is proposed and a robust PnPotts model-like higher-order potential is introduced to refine the resulting depth map. Our method is a natural integration of pixel- and superpixel-level multi-view stereos under a unified energy minimization framework. Experimental results for standard data sets and our own data sets show that our proposed method can satisfactorily handle many challenging factors(e.g., slanted surfaces and poorly textured regions) and can obtain accurate piecewise planar depth maps.

The UV-cured organic-inorganic hybrid nanocomposite （nano-Si-m-PI） was prepared through the photopolymeri- zation of acrylic resin initiated by ethoxysilane-modified multifunctional oligomeric photoinitiator （Si-m-PI）. The es- terification reaction of 2-hydroxy-4＇-（2-hydroxyethoxy）-2-methylpropiophenone （Irgacure 2959） with thioglycolic acid, and the following addition reactions with dipentaerythritol hexaacrylate and then 3-aminopropyltriethoxysilane were carried out for preparing the Si-m-PI. The Si-m-PI exhibits the similar UV absorption and molar extinction coefficient with Irgacure 2959. The photoinitiating activity study by photo-DSC analysis showed that the Si-m-PI possesses high photopolymerization rate at the peak maximum （Rpax） and final unsaturation conversion （Pf） in the cured hybrid films. From the scanning electron microscope （SEM） observation, the SiO2 nanoparticles dispersed uniformly in the formed nano-Si-m-PI, whereas the aggregation of nanoparticals occurred in nano-Irg, which was prepared through the photopolymerization of acrylic resin initiated by Irgacure 2959. Moreover, compared with the UV-cured pure polymer and nano-Irg, the nano-Si-m-PI showed remarkably enhanced thermal stability and mechanical properties.

We investigate the asymptotic stability of the solutions to Boussinesq equations without heat conduction with the initial data near a specific stationary solution in the three-dimensional domain Ω=R^(2)×(0,1).It is shown that the solution starting from a small perturbation to the stationary solution converges to it with explicit algebraic rates as time tends to infinity.

This paper presents a method for differen- tial collision attack of reduced FOX block cipher based on 4-round distinguishing property. It can be used to attack 5, 6 and 7-round FOX64 and 5-round FOX128. Our attack has a precomputation phase, but it can be obtained before attack and computed once for all. This attack on the reduced to 4-round FOX64 requires only 7 chosen plaintexts, and performs 242.8 4-round FOX64 encryptions. It could be extended to 5 （6, 7）-round FOX64 by a key exhaustive search behind the fourth round.
