顾芸  董亚宁 《科技管理研究》2018,(17)

通过包含创新部门的新经济地理增长模型,分析发现知识溢出和高校创新投入对经济增长具有正向影响作用。在此基础上,选取2004—2015年我国省级面板数据,通过构建空间动态面板杜宾模型并采用系统GMM方法,在结构视角下考察高校创新投入对经济增长的影响。结果表明,时间维度上,高校创新投入对经济增长具有促进效应;空间维度上,高校创新投入对经济增长影响具有外部性特征,高校基础研究经费内部支出、高校应用研究经费内部支出对经济增长具有正向溢出效应,且知识溢出和高校创新投入对经济增长的影响在不同区域存在差异性。  相似文献

基于碳税的供应链合作减排补贴策略研究     

孟卫军  姚雨  申成然 《科技管理研究》2018,(9)

在低碳可持续发展背景下,供应链企业会利用各自研发优势合作减排。为研究此类合作减排的补贴策略问题,在基于政府向终端产品收取碳税的政策下,构建三阶段政企博弈模型,对无政府补贴、投入补贴、减排量补贴3种情形进行比较分析。研究表明,在碳税政策下,无论政府是否给予补贴,企业都会进行合作减排;两种方式的补贴均可以提高减排量、企业利润和政府效益,但较投入补贴方式,政府按减排量补贴的效果更为显著。  相似文献   

Accuracy of human motion capture systems for sport applications; state-of-the-art review     

Eline van der Kruk  Marco M. Reijne 《European Journal of Sport Science》2018,18(6):806-819

Objective: Sport research often requires human motion capture of an athlete. It can, however, be labour-intensive and difficult to select the right system, while manufacturers report on specifications which are determined in set-ups that largely differ from sport research in terms of volume, environment and motion. The aim of this review is to assist researchers in the selection of a suitable motion capture system for their experimental set-up for sport applications. An open online platform is initiated, to support (sport)researchers in the selection of a system and to enable them to contribute and update the overview. Design: systematic review; Method: Electronic searches in Scopus, Web of Science and Google Scholar were performed, and the reference lists of the screened articles were scrutinised to determine human motion capture systems used in academically published studies on sport analysis. Results: An overview of 17 human motion capture systems is provided, reporting the general specifications given by the manufacturer (weight and size of the sensors, maximum capture volume, environmental feasibilities), and calibration specifications as determined in peer-reviewed studies. The accuracy of each system is plotted against the measurement range. Conclusion: The overview and chart can assist researchers in the selection of a suitable measurement system. To increase the robustness of the database and to keep up with technological developments, we encourage researchers to perform an accuracy test prior to their experiment and to add to the chart and the system overview (online, open access).  相似文献   

On the integration of model-based feature information in Product Lifecycle Management systems     

《International Journal of Information Management》2017,37(6):611-621

As CAD models continue to become more critical information sources in the product’s lifecycle, it is necessary to develop efficient mechanisms to store, retrieve, and manage larger volumes of increasingly complex data. Because of their unique characteristics, 3D annotations can be used to embed design and manufacturing information directly into a CAD model, which makes models effective vehicles to describe aspects of the geometry or provide additional information that can be connected to a particular geometric element. However, access to this information is often limited, difficult, and even unavailable to external applications. As model complexity and volume of information continue to increase, new and more powerful methods to interrogate these annotations are needed.In this paper, we demonstrate how 3D annotations can be effectively structured and integrated into a Product Lifecycle Management (PLM) system to provide a cohesive view of product-related information in a design environment. We present a strategy to organize and manage annotation information which is stored internally in a CAD model, and make it fully available through the PLM. Our method involves a dual representation of 3D annotations with enhanced data structures that provides shared and easy access to the information. We describe the architecture of a system which includes a software component for the CAD environment and a module that integrates with the PLM server. We validate our approach through a software prototype that uses a parametric modeling application and two commercial PLM packages with distinct data models.  相似文献

Three-dimensional trunk kinematics in golf: between-club differences and relationships to clubhead speed     

Christopher Joyce  Angus Burnett  Jodie Cochrane  Kevin Ball 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):108-120

The aims of this study were (i) to determine whether significant three-dimensional (3D) trunk kinematic differences existed between a driver and a five-iron during a golf swing; and (ii) to determine the anthropometric, physiological, and trunk kinematic variables associated with clubhead speed. Trunk range of motion and golf swing kinematic data were collected from 15 low-handicap male golfers (handicap = 2.5 ± 1.9). Data were collected using a 10-camera motion capture system operating at 250 Hz. Data on clubhead speed and ball velocity were collected using a real-time launch monitor. Paired t-tests revealed nine significant (p ≤ 0.0019) between-club differences for golf swing kinematics, namely trunk and lower trunk flexion/extension and lower trunk axial rotation. Multiple regression analyses explained 33.7–66.7% of the variance in clubhead speed for the driver and five-iron, respectively, with both trunk and lower trunk variables showing associations with clubhead speed. Future studies should consider the role of the upper limbs and modifiable features of the golf club in developing clubhead speed for the driver in particular.  相似文献

如何利用移动设备的位置识别功能开发创新性的移动应用系统,是众多研究者和商业应用开发者关注的焦点。基于位置识别的移动学习系统5R自适应框架为实现自适应移动学习环境提供了一套解决方案和标准化结构。5R自适应框架能够根据学习者、位置、时间、移动设备等因素自动生成学习者所需要的学习内容,增强学习者与学习情境之间的交互。5R自适应框架的实施需要描述基于位置的学习内容并使之标签化,建立自适应约束条件和学习内容之间的关系。在基于位置识别的地理课实地考察移动学习过程中,5R自适应框架能够很好地支持这一应用,而且在实现过程中体现出高度的灵活性。  相似文献
