Present a new LVQ wavelet image coding algorithm in which entropy coding and enumeration codes of different length are utilized. For wavelet image coding, there is a problem of mismatch between lattice distribution and the input vector probability density function in traditional LVQ algorithms (such as product-code pyramid VQ and piecewise uniform LVQ).

The best theoretical solution to a partitional clustering problem is to find all possible partitions and choose the partition that minimizes the objective function. However, the enumeration of all possible partitions is impractical even for data sets of moderate size. Therefore, as an alternative, most partitional approaches use an iterative optimization technique. And this could be cause local minimum.

本文在分析了目前聚类的基本方法的基础上，指出以K平均法等为代表的分割聚类虽然理论上找到类的所有划分并使得目标函数最小就可以获得最优解，但由于对于相当尺度的数据集列举所有可能的划分并不现实，因而多数分割方法采用迭代优化技术作为变通。

There are series of papers studying the solvability of an incompressible, viscous, instationary fluid contained in a domian bounded entirely by a free surface. In 1977, Solonnikov proved its local solvability in a Holder space for any initial date but without surface tension. In 1984, he considered the same problem in a Sobolev space with surface tension being taken into account. In I992, Mogilevskii and Solonnikov treated the same problem in a Holder space, where the coefficient of surface tension is not a constant. There are also short-time existence results for the solvability of an incompressible, vicous, unsteady fluid bounded above by a free surface and below by a fixed bottom which approach horizontal planes at infinity. In 1981, Beale proved its local solvability in a Sobolev space for any initial date but without surface tension. In 1983, Allain were concerned with the same problem in R〓 with surface tension but under the assumption that the initial fluid domain was near a horizontal strip. In 1987, he obtained the same result without the preceding assumption. In 1996, Tani solved the same problem in R with surface tension. For the solvability of an incompressible viscous instationary fluid in Ω R bounded inside by a free surface S and outside by a rotating boundary S, in 1995 Ciuperca proved its local existence in a Sobolev space for any initial date but without surface tension. In this paper, we consider the same problem with surface tension.

对于边界完全是由自由边界组成的有界区域中粘性不可压流体的非定常运动问题，Solonnikcv于1977年在忽略表面张力情况下证明了初值问题小时间解在Holder空间的存在性，于1984年在有表面张力情况下证明了初值问题问题小时间解在Sobolev空间的存在性，Mogilevskii和Solonnikov于1992年在表面张力系数可以不是常数情况下证明了初值问题小时间解在Holder空间的存在性；对于上面是自由边界、下面是固定边界且两边界在无限处趋于水平的无限区域中粘性不可压流体的非定常运动问题，Beale于1981年在忽略表面张力情况下证明了初值问题小时间解在Sobolev空间的存在性，Allain于1983年在有表面张力情况下证明了R中初值问题小时间解在Sobolev空间的存在性，但其中假定初始区域近似是个水平条，他于1987年去掉了这个假定得到同样的结果，Tani于1996年在有表面张力情况下证明了R中初值问题小时间解在Sobolev空间的存在性；对于R中内面是自由边界、外面是旋转边界S的有界区域中粘性不可压流体的非定常运动问题，Ciuperca于1995年在忽略表面张力情况下证明了初值问题小时间解在Sobolev空间的存在性，本文考虑了在有表面张力情况下初值问题可解性问题。

The purpose of this dissertation lies in perfecting relative laws of administration of medical waste,according to the lawmaking and law system of foreign countries.meanwhile,the notion is provided to consummate relative law system and achieve the purpose of holding in the administration of medical waste,environment protect and human health.this dissertation puts forward first-step conceivableness of perfecting lawmaking and law system concerning the administration to disposal of medical waste.because our country's law system concerning medical waste is too immovable and abstract,this research will make our country's law system of the medical waste more concrete and more definite,which will strengthen the operability in the fulfillment and make the lawmaking spirit embodied.simultaneously it provides legal basis and policy support for the administration to disposal of medical waste.the problem of the administration of medical waste enlarges the difficulties of disposal process.to perfect lawmaking,law-executing,law-supervising.is advantageous to strengthen the administration to disposal of medical waste of our country.meanwhile it has theoretic meaning and application value for environment safety and human health.this dissertation is totally divided into four parts.the first part explains the current condition of the administration to disposal of medical waste of our country,which introduces the concept of medical waste,the harm of medical waste,the necessity of administration, current lawmaking condition and present law system of the medical waste.the second part introduces the general situation of lawmaking concerning the administration to disposal of medical waste of the united states,eu,japan and korea.simultaneously it explains the apocalypse of administration to disposal of medical waste of our country.the third part points out the existent law problem of the administration to disposal of medical waste,including lawmaking problem,law enforcement problem and law system problem.the fourth part aims at the relative suggestions to the existent law problems of the administration to disposal of medical waste of our country.the suggestions want to raise lawmaking layer,perfect lawmaking contents,strengthens law enforcement,practice the law system of the manufacturer to be responsible for the medical waste.meanwhile,it gives the advice on the punishment-compensation system,the conduct permit system and the risk fund system.

Firstly, the approach formulates a cost functional to turn the inverse problem into a constrained minimization problem according to least squares criterion, then the resulting constrained minimization problem is transformed into an unconstrained minimization problem by using a penalty function technique, and then the closed Fr chet derivatives of the Lagrange function with respect to the properties are derived based on the calculus of variations, finally, one can solve the resulting problem by using any gradient-based algorithm and the finite-difference time-domain method.
