Using the analytic hierarchy process (AHP) analysis, I further find that financing costs, service value-added, and products diversity are the three most important competitive factors for the auto financial leasing service providers. This is the case for both the corporate and individual customers in the sample. By contrast, the factors of sales channel and government relationship are found to be much less important. Finally, through an in-depth case study of the leasing company Shanghai Auto Financial Leasing, I find that the key factors determining the customers’ credit default risk are interest rate and automobile type. I also investigate factors that influence business risk during the automobile procurement stage, at the selling stage, and toward the disposition stage. The managerial implications of the above results are discussed throughout the thesis.
The experience gained is the understanding of how a cost function of a system works, including the tracking error, speed of the system, the robot’s effort, and the human’s effort. Also, this two-agent system, results into a two-agent adaptive impedance model with an input for each agent of the system. This leads to a nontraditional linear quadratic regulator (LQR), that must be separated and then added together. Thus, creating a traditional LQR. This new experience can be used in the future to help build better safety protocols on manufacturing robots. In the future the knowledge learned from this research could be used to develop technologies for a robot to allow to adapt to help counteract human error.
efficiency in resources allocation, and lacking in quality on personnel training. To achieve core competitiveness and value creation, it is important that the health nutrition & wellness industry must meet the needs of Chinese market and its customers with a customer centric perspective to design a firm’s organization strucrture and management processes. This thesis is based on an analysis of the competitive landscape faced by the nutrition & wellness industry as exemplified by By-Health.Ltd. The investigation begins with an analysis and synthsis of the common industry practices on sales & distribution channels for their underlying similarities and differences in product strategies, branding strategies, and agency models on incentive design and profit sharing mechanisms. Through an empirical survey, this thesis also investigate customer’s demand for nutritious and healthy products. The results through factor analysis reveal that such demands are driven by individual factor, product factor, enterprise factor and environmental factor. The study concludes with a proposed framework to link customer value through three innovative designs in sales and distribution: community marketing model, sharing marketing model and Internet factory marketing model.
A series elastic actuator is one of the many actuation mechanisms employed in exoskeletons. In this mechanism a torsion spring is used between the actuator and human joint. It serves as torque sensor and energy buffer, making it compact and
safe.
A version of knee exoskeleton was developed using the SEA mechanism. It uses worm gear and spur gear combination to amplify the assistive torque generated from the DC motor. It weighs 1.57 kg and provides a maximum assistive torque of 11.26 N·m. It can be used as a rehabilitation device for patients affected with knee joint impairment.
A new version of exoskeleton design is proposed as an improvement over the first version. It consists of components such as brushless DC motor and planetary gear that are selected to meet the design requirements and biomechanical considerations. All the other components such as bevel gear and torsion spring are selected to be compatible with the exoskeleton. The frame of the exoskeleton is modeled in SolidWorks to be modular and easy to assemble. It is fabricated using sheet metal aluminum. It is designed to provide a maximum assistive torque of 23 N·m, two times over the present exoskeleton. A simple brace is 3D printed, making it easy to wear and use. It weighs 2.4 kg.
The exoskeleton is equipped with encoders that are used to measure spring deflection and motor angle. They act as sensors for precise control of the exoskeleton.
An impedance-based control is implemented using NI MyRIO, a FPGA based controller. The motor is controlled using a motor driver and powered using an external battery source. The bench tests and walking tests are presented. The new version of exoskeleton is compared with first version and state of the art devices.

本课题发现当前的政务平台逐步引入PPP模式,借助社会资源开发政务平台。但是,PPP模式是否有利于政务平台的建设,受到哪些因素的制约,如何更好地利用PPP模式进行开发工作,这些问题在现前的研究中没有得到很好地探索。带着这些问题,本课题对PPP模式在政务平台建设中的作用进行了深入剖析。主要研究内容如下:
在第一部分中,本课题政府公共服务和政务相关理论进行了全面整理,发现政务平台要想走出一条健康发展之路,需要借助社会资源进行市场化,而PPP模式符合当前政务平台建设的需要。本文对PPP模式在国内外电子政务的应用进行了分析,提出了本文的研究主题。
在第二部分中,本文对华东地区50座城市的政务平台进行了调研,对常见问题进行了整理,发现PPP模式已经广泛应用于政务平台建设中,且主要有四种模式,本文对50座城市的政务平台建设情况进行了数据采集,并进行了深入分析。
在第三部分中,结合调研现状和文献研究成果,提出了PPP模式影响政务平台建设的相关假设,并构建了计量模型。通过短面板分析验证假设,并进行了Robust分析,证实结论的普适性。
在第四部分中,本文分析了研究结果,认为政务平台采用PPP模式能够有效促进政务平台的建设水平,提高用户满意度;并且PPP模式与合作企业的估摸、信息的透明程度和平台的交互能力存在显著的交互作用,共同影响用户对政务平台的评价。政府引入PPP模式,充分对接可利用资源,并加强盈利控制,对当前政务平台的建设是具有积极意义的。
