协同虚拟维修过程中的虚拟人体维修操作控制

针对操作人员难以在有限的光学运动捕捉设备捕捉范围内自由运动的问题,开展了协同虚拟维修过程中的虚拟人体维修操作控制研究。基于光学运动捕捉设备对操作人员的下肢动作进行捕捉,根据实时识别结果控制虚拟人体进行大范围运动。针对维修操作过程中的虚拟人体手部运动控制,分析了虚拟人体的手部交互过程,提出了一种基于动态贝叶斯网络的维修操作智能辅助方法。以某液压缸协同式虚拟维修操作仿真平台为例验证了方法的有效性。该方法实现了对虚拟人体维修操作过程的有效控制,具有实时性好、交互性与感知性强等优点。     

VRML场景中的智能替身研究

给出VRML场号中的智能替身模型，使得替身可以更好的理解用户的意图。首先，利用参数化的方法构造替身模型，使得用户可以更快捷的定制个性化的替身；在此基础上，分层次的动作模型实现了从高层的面向任务的动作到底层替身物理动作的高效分解与映射；最后，多通道的交互方式使得用户可以通过更自然的方式控制自己的替身。VRML场景中的智能替身研究为VRML多用户虚拟场景中替身交互，以及替身与场景交互的研究提供了基础。     

A History of the Action Learning,Action Research,and Process Management Association (ALARPM): From Brisbane (Australia) to the World Through Inclusion and Networks

Action Learning, Action Research, and Process Management Association (ALARPM) is an organization of volunteers dedicated to the international expansion of action learning, action research, and process management, through world congresses. It has existed for over a dozen years now, despite significant stresses and strains, and has successfully conducted five world congresses with a sixth one in 2003. This history of ALARPM shows that a small group can set out to be international and inclusive from the beginning, so long as it also develops processes to sustain itself internally.     

复杂系统研究与本体论的复兴

讨论了复杂系统研究的若干本体论问题。指出，由于复杂性研究和系统科学在方法论上建立起从具体科学到哲学本体论的连接桥梁，所以它就推翻了上个世纪旷日持久的哲学上的拒斥形而上学运动，恢复了本体论在哲学中的地位。同时，系统科学和复杂性研究还为过程哲学、突创进化论哲学、过程机制研究和广义目的性与广义价值论的研究提供了有力的论点和论据，使本体论哲学发生了重大的变革。     

基于游客类型的旅游企业自愿环境行动演化模型

基于游客类型的企业自愿环境行动演化模型表明,当景区有更高比例的生态游客和较高的资源环境自净能力时,就会有更多的旅游企业实施自愿环境行动。景区游客总数量、企业总数量对旅游企业实施自愿环境行动的影响具有不确定性。     

Interdisciplinarity: Potentials and Challenges

Interdisciplinarity, as a concept and practice, is reviewed and related to a recent article (Romm, 1998) in this journal. Authors advocating interdisciplinarity for social research and problem solving seem to have diverse, if often largely implicit, epistemological, and other assumptions informing their proposals. Romm (1998) develops and advocates a critical and reflexive orientation for tying interdisciplinarity to action research and related endeavors. For some academicians, however, interdisciplinarity appears to be considered a relatively unproblematic pursuit of merely selecting appropriate methods. Significant issues and questions concerning interdisciplinary pursuits, particularly in academic settings, exist and are briefly explored, based on the experiences and perceptions of the author. Basic structures and processes found in fields such as action research/science and management systems often seem neglected and very much needed for interdisciplinary inquiry and knowledge construction.     

Power-Based Arbitrary Decisional Actions in the Resolution of MIS Project Issues: A Project Manager's Action Research Perspective

As a management information systems (MIS) project manager and an action researcher, the author examined, over time, the influence on information system development (ISD) of the informal sociopolitical organizational actions. The paper reports two cases of action research findings concerning the effect on ISD project implementation processes of power-based arbitrary decisional actions in bureaucratic environments. The research focused on the relationship of such unilateral actions to the interconnected subprocesses of deliberate and conscious attempts by the ISD project members to define and resolve system implementation issues. A suggested conceptual framework for the issue-resolution processes (IRP's) and obstacle-coping processes (OCP's) is based on the author's IRP/OCP-related behavioral constructs and theoretical models dealing with soft-systems issues, especially appreciative system theory and soft-systems methodology, and innovative flexible, "complementarist" (Sinn, 1998) or pluralist problem-solving approaches.     

汽包水位波动与晃荡热力学模型的开发与仿真研究

汽包水位波动与晃荡产生的原因有两方面,即水动力学和热力学方面的原因;为建立汽包水位波动与晃荡的仿真模型,建立汽包水位波动与晃荡热力学模型是最根本的,基于模块化建模的方法,以汽包集总参数模型为参考模型,为汽包水位波动与晃荡热力学模型开发了四种可行的建模方案,通过对汽包“虚假水位”与设计工况点的动态仿真结果的研究,确定其中最优的方案作为汽包水位波动与晃荡热力学模型的建模方法,并基于该方法建立了汽包水位波动与晃荡热力学模型,为建立完整的汽包水位晃荡模型与开发先进的汽包水位控制策略奠定了坚实的基础。     

防卫行动指挥训练模拟系统研究

反恐斗争是一种特殊的军事斗争形式,是当前军事训练领域的一个重要内容。为满足国内城市“反恐、防恐”的需要,满足驻城部队军官指挥行动训练的需求,我们研制了防卫行动指挥训练模拟系统。首先介绍了该训练模拟系统要达到的总体战技指标、实现的主要功能,然后给出具体实现的硬件构成和各相应的模块子系统、各个分系统的相互关系,以及电台模拟与实时语音通信技术,最后介绍了系统研制过程当中所采用的关键技术。该系统在某装甲步兵分队应用后,反映效果较好、收效明显,对驻城区部队的“反恐”训练具有很强的推动作用。     

In Search of Resonance

In this paper I explore the possibility of a complementary relationship between action research and the management and systems sciences. A range of purposes that action researchers and management and systems scientists pursue is initially set out. The paper then explores whether this diversity of purposes and the ways they recommend people to proceed may come together in a new whole that is greater than the sum of its parts. A potentially useful realization of this for practice is a reflexive process of critique, choice, and action, which is elaborated on. The paper then investigates what view of holism arises from the preceeding discussions.
