Research of High-accuracy Pedestrian Navigation Algorithm Based on MEMS Sensors
伴随微电子技术迅猛发展,导航技术的应用领域已渐渐从军事化转向了商用化。近几年,室内导航技术得到了大力发展,受到了越来越多企业和民众的重视。但现有的室内定位系统多是基于基础设施实现,其缺点非常明显:需要提前在需要导航定位的环境中安装大量外部设备,投入成本不菲,且精度仍有待提高。本文拟设计一种基于自身传感器的行人导航系统来解决上述缺陷。 捷联式惯性导航技术不仅可以避免需要外设、投入高等缺陷,并且在短时间定位精度相当高,但随着时间的推移,其存在累积的漂移误差。针对这一点,本文基于卡尔曼滤波设计出一种有效补偿累积误差的算法。首先,通过捷联式惯性计算模块对惯性测量信息进行积分解算,由角速度积分求解出姿...With rapid development of microelectronics technology, the application area of navigation technology gradually shifted from military to the public. Indoor positioning technology is developing dramatically in recent years, attracting more and more attention from enterprises and the public. However, the disadvantage of currently existing indoor positioning system is obvious. Because most of these sy...学位:工程硕士院系专业:信息科学与技术学院_集成电路学号:2312011115301
Research on Economic Consequences of Segment Reporting in Chinese Listed Companies
随着全球经济的不断发展和一体化格局的逐步形成,众多企业突破了传统单一的经营领域与地域范围,多元化经营成为十分普遍的现象。与此同时,因多元化经营带来的企业各分部利润率、未来前景和风险的差异严重影响了投资者的决策质量,从而使得有关分部报告信息披露的研究不断增加。分部报告信息披露的规定对我国证券市场的各个参与主体产生了怎样的影响,国内学者尚未给出较为系统的回答。本文从信息披露具有经济后果这一主旨出发,结合我国分部报告发展和披露的现实状况,采用规范和实证相结合的研究方法,从市场评价和企业自身两大视角考察了分部报告信息披露的经济后果。主要得出以下结论: 第一,管理当局自身选择性披露的动机和监管部门的强...As the economic globalization comes into being, a lot of companies have broken down the range of operating activities and regions. Diversification has been widespread phenomenon across the world. At the same time, investors’ decisions have been gradually affected by the differences of segment profitability, future prospect, and risks. This makes the research on segment information disclosure incre...学位:管理学博士院系专业:管理学院会计系_会计学学号:1512005140295
Literary Reflection on Chinese Ecological Problems Inspired by Ariyosi Sawako's Report of China
日本当代著名女作家有吉佐和子的《有吉佐和子的中国报告》,既表达了对20世纪70年代中国生态问题的忧虑,也肯定了当时中国的一些环保举措。本文从生态批评的视角剖析作者在该报告中对中国生态问题的思考,指出有吉佐和子对生态问题的文学思考具有现实意义,其具有国际化视野的文学创作,客观上为世界生态文学的发展作出了贡献,这也是今天重读该作的重要意义所在。Ariyosi Sawako's Report of China,which was written by Ariyosi Sawako,a famous Japanese contemporary writer, is the reportage about China.This book not only expresses deep concerns about Chinese ecological problems in the 1970s, but also confirms some environmental protection measures of China at that time.From the perspective of eco-criticism, this paper makes detailed analysis of Chinese ecological problems in Ariyosi Sawako's literary creation.According to this paper, Ariyosi Sawako's literary reflection on ecological problems has a realistic significance and her literary creation of internationalized vision contributes to the development of world eco-literature objectively, which is significant for us to reread "Ariyosi Sawako's Report of China"now.2013年度教育部人文社会科学研究规划青年基金项目“日本当代生态文学研究”(13YJC752028); 辽宁省教育厅2012年度人文社会科学研究项目“日本当代生态文学研究”(W2012072); 大连工业大学2012年教育教学改革研究项目“跨学科视野下的文学课程建设与研究”(JGLX1243)的阶段性成
The Study on The Right of Insurance Subrogation
保险代位求偿权作为保险法领域一项重要的法律制度,是民法代位权制度和保险损失补偿原则相结合的产物,是保险法的核心内容之一。保险代位求偿权作为保险的一项基本制度已经被世界各国和地区加以确认。我国法律对于保险代位求偿权的规定并不完善,理论上缺乏深入研究,实践中出现了很多问题。鉴于此,本文将保险代位求偿权作为研究对象,试图把握保险代位求偿权的真正内涵,研究保险代位求偿权的理论基础,明确保险代位求偿权的运行及其保护,以期对完善我国保险代位求偿权制度有所参考。文章除绪论和结语外,正文共分为四部分: 第一章保险代位求偿权基础理论。文章首先明确了保险代位求偿权的概念,然后探讨了保险代位求偿权的基础理论即基于...As an important part of insurance legal system, subrogation is the product of the combination of subrogation right of civil law and the principle of compensation in insurance law system, has now been confirmed as a basic system by most of the countries and regions in the world.

Research on the Exploitation of Aluminum Alloy Vacuum Die-casting Part for the Lightweight Coach Body
安全、环保、节能是汽车发展的永恒主题,特别是在当今汽车拥有量急剧上升、环境受到严重威胁、能源日益紧缺的时刻,汽车轻量化尤为重要。以铝代钢的轻量化客车作为客车主要发展方向,受到人们越来越多的关注。但是,客车轻量化在国内仍停留于试验阶段,主要因为仍未找到有效的措施解决因车身杆件品种多、品质难控制、连接部位缺陷多而造成车身强度达不到要求等问题。本课题合作企业之一,多年前开发的一款全铝车身就因杆件断裂而中断了研究。 本文针对上述问题,开展了客车轻量化关键技术――铝合金真空杆件开发研究。首先着重研究了现有客车车身的结构特点,根据车身应力分析结果与材料特性,将原钢质车身底架的行李舱杆件铝化为具有同一截面...Safety, environmental protection and energy saving are the eternal topics of auto development, especially in the time while the gross of automobile have risen sharply,a serious threat to the environment and energy shortages, it is important to decrease the weight of automotive.

Study on the determinants of executive compensation and sensitivity of executive compensation-performance mechanism with tourism listed companies
高管薪酬一直是实务界和学术界所关心的话题。面对天价薪酬,普通大众质疑高管薪酬的公正性;而学术界人士关心高管薪酬的有效性。虽然不乏学者对此研究,但是之前的研究多集中在薪酬水平决定因素的探讨上,鲜有人探讨公司治理因素对薪酬绩效敏感性的影响。但是事实上,对于公司股东而言,高管薪酬能否起到预期的激励效果比高管薪酬水平本身更重要。同时,之前的研究大多针对所有上市公司或者其他行业,少有学者研究旅游上市公司高管薪酬问题。由于旅游行业有自身的特点,无法直接套用其他样本的研究结论,有必要对其进行实证研究。 本文首先在对目前学术界对旅游上市公司研究现状的了解基础之上,锁定本文的研究重点;继而在对高管薪酬研究进展...Executive compensation is always a topic concerned by both pragmatical and academical fields.
