船舶液力耦合器的人工神经网络的数学建模

从船舶动力装置动态建模与仿真的实际需求，引出了其主要部件之一的液力耦合器数学建模在稳／动态特性研究中的重要性，以及利用其试验曲线(输入特性形式)作为数据源去构建准稳态数学模型的困难之处：寻找一种通用的数学表达形式，以实现①液力耦合器在额定工况及其附近的试验曲线的内插与外廷；②过渡工况液力耦合器数学模型的设计(如液力耦合器接合和脱开过程其滑差从100％向额定滑差值方向的变化)。本文介绍了人工神经网络方法在液力耦合器动态建模中的应用。文章先介绍了其数学建模的思路和要点：①选择人工神经网络算法(包括传递函数)与结构(人工神经网络隐含层数目和神经元个数)；②提高人工神经网络泛化能力的措施；③利用专业知识扩充人工神经网络训练用的数据样本。然后叙述了其数学模型在某船舶动力装置稳态、动态特性计算机仿真研究中的某些有意义的结果：①正常航行(四机双桨)稳态工况时各车令下液力耦合器的滑差；②不同螺旋桨螺距下的液力耦合器接合过程的滑差变化；③怠速→前进五的急加速过程的滑差变化。

复印与传真件的证据补强

【案情】2003年10月14日，被告浙江特产集团有限公司（以下简称”特产公司”）向原告华展国际货运代理有限公司（以下简称”华展公司”）传真一份出13货物明细单，委托华展公司代为办理一批出口到法国勒阿夫勒的货物的报关订舱手续，并要求华展公司告之运价。华展公司收到明细单后，在该明细单上注明海运费和集卡运费后回传特产公司。随后，华展公司派车到特产公司指定地点装箱，并代为订舱、报关。货物出运后，华展公司向特产公司开具发票收取海运费、集卡运费和订舱、报关，THC（港口附加费）等。特产公司按华展公司开具的发票金额支付了款项。原告据以证明上述事实的证据中，除了特产公司的付款凭证为原件外，其余证据均为传真和复印件。     

Purification effects of C2Cl6 on A00 aluminum

The effects of several fluxes on purification, microstructures and properties of A00 aluminum have been studied. The experimental results and analyses indicate that many cracks and large porosities exist in the surface film above the melt purified by C₂Cl₆ and that the film is floc and mostly composed of Al₂O₃ and pure aluminum, which carries many carbon particles and AlCl₃ not fully volatilized. And then over 50% (mass fraction) of the all-melting residue is pure aluminum, which is one of the major reasons for high melting loss. Moreover, because of a mass of gas bubbles and a state of seethe, there are many inclusions which size is under 10 ??m in the microstructure of A00 aluminum purified with C₂Cl₆ or fluxes containing C₂Cl₆. With this purifying method, the aluminum crystal grains are extended along the radius that was observed firstly and the average crystal size of A00 aluminum are about 100?C150 ??m. In addition, small size inclusions have little affected on tensile strength and micro inclusions under 10 ??m have little affected on elongation.     

A data model applied to the knowledge-based ICAS

Image-guided computer aided surgery system (ICAS) contributes to safeness and success of surgery operations by means of displaying anatomical structures and showing correlative information to surgeons in the process of operation. Based on analysis of requirements for ICAS, a new concept of clinical knowledge-based ICAS was proposed. Designing a reasonable data structure model is essential for realizing this new concept. The traditional data structure is limited in expressing and reusing the clinical knowledge such as locating an anatomical object, topological relations of anatomical objects and correlative clinical attributes. A data structure model called mixed adjacency lists by octree-path-chain (MALOC) was outlined, which can combine patient's images with clinical knowledge, as well as efficiently locate the instrument and search the objects' information. The efficiency of data structures was analyzed and experimental results were given in comparison to other traditional data structures. The result of the nasal surgery experiment proves that MALOC is a proper model for clinical knowledge-based ICAS that has advantages in not only locating the operative instrument precisely but also proving surgeons with real-time operation-correlative information. It is shown that the clinical knowledge-based ICAS with MALOC model has advantages in terms of safety and success of surgical operations, and help in accurately locating the operative instrument and providing operation-correlative knowledge and information to surgeons in the process of operations.
