摘要：The construction and shape of UUVs are described in the paper. UUV design is the shape of the overall design of unmanned underwater vehicle should first be resolved UUV underwater vehicle directly affects the shape of the resistance and noise, which is related to energy, payload, maneuverability and concealment UUV problem The main characteristic and parameter tables for foreign torpedo shape, fiat shape and anomalous shape are also given in the paper. The general layout of typical foreign UUVs is analyzed in detail. And the total layout figure and interior constructive figure are introduced. Torpedo-type because of its good water power and low noise, no one has been the main form of underwater vehicle-like, and many designers are now highly favored because of its stable performance, anti-environmental interference capability. Other irregular shapes designed primarily for the completion of a specific task, according to the specific environment and mission requirements. According to comparing and summarizing, some suggestions and conclusions are oresented.

摘要：This paper is concerned with the optimal design of an obstacle located in the viscous and incompressible fluid which is driven by the steady-state Oseen equations with thermal effects. The structure of shape gradient of the cost functional is derived by applying the differentiability of a minimax formulation involving a Lagrange functional with a space parametrization technique. A gradient type algorithm is employed to the shape optimization problem. Numerical examples indicate that our theory is useful for practical purpose and the proposed algorithm is feasible.

摘要：The objective of the present article is to find an optimal design of a fan inlet to reduce the amount of noise radiated to the far field from the system. Against the gradient-based optimization algorithms, we employ here a method based on measure theory which does not require any information of gradients and the differentiability of cost function.

摘要：为了从复杂背景中识别出交通标志,提出了一种基于改进shape Context的分层识别系统。在RGB空间对图像进行分割,去除干扰,得到感兴趣的区域(ROI)。提取感兴趣区域的边缘信息,用标记法确定该区域的形状,完成外部形状粗分类。利用改进的shape Context算法对交通标志内部图形进行细分类,完成交通标志的识别。实验结果表明,该方法能够快速有效地识别出复杂背景中的交通标志。

摘要：This paper presents the major analyses carried out on shape and form’s characteristic database from Japanese and Vietnamese traditional daily products(TDPs).The aim of the research is to recognize the vital specifications representing for a national style by comparing two different countries *** using Quantification Theory Type III and Cluster analysis,firstly,the analyses were undergone separately for Japanese and then Vietnamese product data in succession so that a view of general direction for each country was *** result showing a difference in scale of“Complexity”and“Specification”axis between Japan and Vietnam leads to performance of the analysis done on combine database of the two countries to get a clearer view of correlation between ***,the biggest difference between the two countries lies in“Form”(Geometric—Organic)***,for studying more deeply into outline of product shape,the main ratios that affect the appearance or gorgeousness of product’s outline were taken into account and *** comparing this result to the previous ones,finally a wider and more detail perspective of Japan and Vietnam shape’s specification in a mutual relationship was discovered.
