| 1 | 无线网络定位综述显示文摘结合无线网络技术,从无线网络定位数学模型的角度对定位问题进行了统一的形式化描述,该描述涵盖测量与距离估算技术、二维空间或多维空间中的定位映射关系以及绝对定位和相对定位的定位需求;论文由模型映射关系是否存在的问题引出了无线网络定位的可行性问题,以唯一实现理论以及刚性图理论作为无线网络定位的可行性模型并对其进行了分析总结;在数据层面对定位系统的测量技术以及信息采集技术进行了分析,将距离测量技术,角度测量技术以及距离估算技术从数学模型角度统一为有用信息采集,并将能用于定位的信息涵盖进来,以此作为定位模型优化与扩展的基础;单目标网络的定位算法较多,但其数学本质上是对同一类目标函数不同的求解方法,该文从数学模型及其优化方法的角度对其进行了分析,总结了不同解法的相似效果;与单目标网络定位不同,多目标网络定位问题虽然定位模型统一,但其求解方法却不尽相同,该文对半定规划方法、多维标度方法以及非线性映射曲元分析方法进行了总结;在对数据采集技术,定位方法进行了总结后,该文系统分析了信息集合对定位算法的影响,从功能上将各种定位技术分为信息采集技术、定位可行性理论、定位模型以及定位优化技术,提出了系统设计层面定位性能提高的主要设计思路,从定位方案的选取上将优化技术看成定位系统中的可选项,基于定位优化技术的相对独立性,提出了定位方案的分治策略;随后该文对定位评估指标中的误差指标和统计学指标进行了总结,以此作为定位性能评估的主要手段;最后提出了无线网络定位领域理论及技术所面临的问题与挑战. | 钱志鸿 孙大洋 LEUNG Victor | 2016 | 计算机学报2016，39，6： | 74 |
| 2 | 含有取向纳米纤维束的神经移植物构建与神经修复应用研究显示文摘为提高纳米纤维神经移植物的接触引导,设计了一种含有取向纳米纤维束的'芯鞘'型神经移植物,它利用静电纺高取向纳米纤维膜,两次卷绕形成'芯'和'鞘',最后通过静电纺丝喷覆而成。利用扫描电镜观察并表征了纤维及其移植物形态,测试了力学性能,将此移植物用于大鼠10mm坐骨神经缺损,术后两月通过体外刺激和组织学观察了修复效果。结果表明:通过调整静电纺收集转辊转速可获得高取向聚乳酸纳米纤维,纳米纤维膜工程应力和伸长率达到(49.32±14.83)MPa和17.71%±0.06%,利用该膜构建的神经移植物缝合强力达到(1.18±0.40)N/针,能支持与保护神经再生,移植两月后,大鼠能够感知热与外力刺激,组织学观察发现,有神经纤维和血旺细胞长入神经移植物,证明了该构建技术的可行性,并有可能为神经修复提供一种新的移植材料。 | 尹桂波 Victor Leung Frank.K.Ko Wolfram Tetzlaff 刘婕 | 2017 | 现代纺织技术2017，25，6： | 2 |

| 4 | A Fast Local Level Set Method for Inverse Gravimetry显示文摘We propose a fast local level set method for the inverse problem of gravimetry.The theoretical foundation for our approach is based on the following uniqueness result:if an open set D is star-shaped or x3-convex with respect to its center of gravity,then its exterior potential uniquely determines the open set D.To achieve this purpose constructively,the first challenge is how to parametrize this open set D as its boundary may have a variety of possible shapes.To describe those different shapes we propose to use a level-set function to parametrize the unknown boundary of this open set.The second challenge is how to deal with the issue of partial data as gravimetric measurements are only made on a part of a given reference domainΩ.To overcome this difficulty,we propose a linear numerical continuation approach based on the single layer representation to find potentials on the boundary of some artificial domain containing the unknown set D.The third challenge is how to speed up the level set inversion process.Based on some features of the underlying inverse gravimetry problem such as the potential density being constant inside the unknown domain,we propose a novel numerical approach which is able to take advantage of these features so that the computational speed is accelerated by an order of magnitude.We carry out numerical experiments for both two-and three-dimensional cases to demonstrate the effectiveness of the new algorithm. | Victor Isakov Shingyu Leung Jianliang Qian | 2011 | Communications in Computational Physics2011，10，9： | 1 |
