浅析侵害债权制度的若干问题

债权作为民事权利的内容之一 ,同样具有不可侵害性 ,但侵害债权仅指第三人实施的侵害行为 ,其构成要件有别于一般的侵权行为 ,主观上必须具有侵害债权的故意。侵害债权人与债务人在法律上构成“不真正连带债务”关系。     

考虑通行约束和运力限制的灾后应急物资联合调度优化研究

考虑到灾后路网受损难以运输应急物资，本文研究了应急响应中车辆-直升机联合调度的路径优化问题。针对受灾地区的实时路况，通往灾区的救援工具受到数量以及装载量的约束，本文将受灾点等待救援的平均时间最短以及应急网络总费用最低设为目标，构建运力受限条件下带通行约束的救援物资联合运输多目标优化模型，然后根据随机邻域搜索变异和分级交叉的思想构建出一种带精英策略的非支配排序混合进化算法（NSHEA-II）得到模型的解，并利用算例分析对该算法进行可行性检验。结果发现，本文构建的NSHEA-II算法相对NSGA-II算法能够得到较好的结果且波动性较小，这为决策者制定救援物资的配送方案提供有效的技术支撑。     

A joint modelling approach for clustered recurrent events and death events

In dental implant research studies, events such as implant complications including pain or infection may be observed recurrently before failure events, i.e. the death of implants. It is natural to assume that recurrent events and failure events are correlated to each other, since they happen on the same implant (subject) and complication times have strong effects on the implant survival time. On the other hand, each patient may have more than one implant. Therefore these recurrent events or failure events are clustered since implant complication times or failure times within the same patient (cluster) are likely to be correlated. The overall implant survival times and recurrent complication times are both interesting to us. In this paper, a joint modelling approach is proposed for modelling complication events and dental implant survival times simultaneously. The proposed method uses a frailty process to model the correlation within cluster and the correlation within subjects. We use Bayesian methods to obtain estimates of the parameters. Performance of the joint models are shown via simulation studies and data analysis.     

多波段光学探测系统的探测概率研究

针对光学联合探测子系统探测概率的不同特点,提出一种新的系统工作模式,使系统的最终探测概率有较大提高。当子系统的探测概率均比较低时,直接对子系统的探测数据进行融合,可以获得较高探测概率;当各子系统探测概率相差较大时,可先对探测数据进行选择,然后再进行数据融合,这样可以在总探测概率减小不大的情况下,使虚警概率明显降低。     

中外合资企业“独资化”的若干法律问题

近些年来，外商对华直接投资中外商独资企业的比重明显提高，并且原有的一些中外合资企业的外国投资者尤其是跨国公司，亦纷纷通过受让中方股权或增资扩股的方式将合资公司转变为外方控股或独资的公司，呈现出一股“独资化”的趋势。合资企业的“独资化”趋势有其深刻的时代背景和内在原因，并将对我国经济的发展带来深远的影响。本文对合资企业“独资化”过程中的增资扩股、股权转让及其审批、股权交割完成的标志以及股权转让协议的法律适用等问题进行探讨，并提出相关立法建议。     

论连带责任中求偿权的实现

求偿权的性质应采纳主观共同关系说。求偿的要件应包括须有债务人共同免责、债务人有财产上的给付行为、该债务人的履行无须超过其应负担部分。求偿权的行使应受到必要的限制。求偿权应通过一次诉讼、多次执行的方法得到实现     

正常青年人行走步态的实验研究

以VICON步态分析系统对5名年龄身高体重均相近的正常青年人的常速行走步态进行了实验研究.得到了青年人常速行走步态的基本参数,给出了关节角度的统计曲线,并对单支撑期内各关节角度进行了分析.比较了左右两侧关节角度的差异.结果表明,正常行走左右两侧关节角度存在着差异,以左右侧关节角度差异度结合时相对称性指标可以更合理地评价步态的对称性.单支撑期内关节角度范围为假肢设计及正常人步态的模拟提供了参考.     

关于共同继承遗产的思考

在我国,由于受传统继承习俗的影响,被继承人死后有数个继承人的,继承人一般并不立即要求分配遗产,往往一段时间后才进行分割。我国《继承法》并未规定继承人在这一期间的法律地位。对遗产分割前遗产的归属及各继承人的法律关系等问题做出明确规定,有利于解决共同继承纠纷,有利于保护继承人和债权人的合法权益,促进社会稳定发展。     

The Interpretation of Line of Regard by Prelingually Deaf Children

The ability of 5- to 12-year-old deaf children to utilise and interpret another person's visual line of regard (where the eyes are looking) was studied in four experiments using cartoon faces. The children had little difficulty in determining whether or not a face was looking directly at them. They had more difficulty, however, with more complex tasks requiring them to infer mental states of desire and intention from line of regard and to ignore line of regard when it was inappropriate to attend to this cue. Deaf children raised in a hearing environment appear to have more difficulty with these more complex tasks than hearing children. The results are discussed in terms of the special difficulties facing some deaf children in the development of skills involving utilisation of line of regard and the implications for the development of joint attentional behaviour, theory of mind and dyadic social interaction in deaf and hearing children.     

基于Shapley值法的移动增值服务价值链利润分配模型

研究对象为任意节点连接和任意支撑的平面框架。一般梁单元由等截面直杆及其杆端的轴向弹簧、切向弹簧和转动弹簧组成，推导得到此类单元的刚度矩阵、单元在8种基本荷载作用下的等效节点荷载。采用Matlab语言编写了适用于一般节点非线性连接框架的静力分析程序，非线性形式为指数函数或多项式函数，可以得到结构不同连接刚度下的节点位移、杆端位移和杆端力。算例显示出节点柔度对结构受力和变形的影响。
