The sufficient conditions to guarantee robust exponential stability for the closed-loop systems are obtained based on Linear Matrix Inequality, moreover, the approach of design of robust H# output feedback controller is introduced.3 The problem of reliable H# control for a class of Lur"e systems with polytopic uncertainties is studied when all control components are operational as well as when some control components experience failures, the design approach of reliable H# controller is also obtained.4 Considering a class of uncertain Lur"e singular system with time-delays, the problem of robust stability is investigated based on Barbalats Lemma and nonsingular linear transformation of model reduction.

To solve the second problem, an approach of irregular QC LDFC codes is proposed. The proposed approach is to replace some sub-matrices by zero matrices and identity matrices at special positions in the given sparse parity-check matrix so as to get a nonsingular square matrix for the construction of the generator matrix.

In general, the dipole components are located at the zero potential plane, called null plane. However, for 3D topographic mapping, many zero potential points can be detected. Instead of testing all the possible points, the proposed approach is to fit the selected zero potentials in terms of a linear plane, i.e. null plane, via least square approach.

一般来说，电偶极的位置都在零电位面上，为了取得零电位面，本研究在三度空间拓朴图映射中找出多点零电位点，然后采用最小平方法，找出一个线性平面通过这些零电位点当做零电位面。

米歇尔斯则在对"寡头统治铁律"进行论证的过程中不自觉地开拓了政治研究的方法，自发运用了政治心理分析和政治团体分析方法。

From this point of view,it ispointed out that there are two kinds of commonalities among diverse prob-lems,one is the relative commonality and the other is the homogenous co-mmonality,and it is advanced that the approach to effectively make useof the relative commonality is to divide models suitably and to set up theorganic relation between models convenient to their composite conection oncondition that models are shared,and the approach to effectively make useof the homogenous commonality is from the view point of different problemsneeding their special models for solving,to convert their special modelrepresentation to comparatively general model depth representation on theprinciple of independence and share of commonality.The articles in thepast has made deep and complete research on model management in aspectssuch as model division and compositive conection,and a number of theoriesand methods are provided,but none of them is in relation to model depthrepresentation.

从这一角度出发，作者指出，在多样性问题中存在两种共性，一种是问题相关共性，另一种是问题同构共性，并提出有效利用问题相关共性的方法是在实现模型共享的前提下对模型进行合理划分和建立便于模型复合联接的各模型之间的有机联系，而有效利用问题同构共性的方法则是从不同问题求解本质上需要的专用模型出发，根据独立与共享原理，将这些专用模型表示转化成较为通用的模型深层表示，以往的文献在模型划分、复合联接等诸方面对模型管理进行了较为深入全面的研究，并从这一角度提出了许多模型表示的理论和方法，但对模型深层表示方面尚没有涉足。

The results indicate that different approaches and product strategies have little effect on the estimates, but the partially constrained approach and the unconstrained approach (except for the one-pair strategy) produce fewer fully proper solutions, more bias and greater root mean square error for smaller sample sizes or poor reliability of the indicators.

结果显示，四种方法与交乘项策略对估计影响不大，但部分限制式方法於三种配对组合、未限制式方法於两两配对与所有配对组合，在适当解比率与参数估计评估表现皆较其他组合差，以小样本或外生潜在变项负载量低时尤为明显。

In this paper, an orthonormal scale transformation approach is proposed, which is a pulse response identification approach based on orthonormal basis expansion.

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.
