Systemic Intervention in a University Department: Reflections on Arrested Action Research

This paper reflects on my experience as an insider researcher attempting to use critical systems ideas and practices to promote quality improvement in a university engineering department. Reflection is a key part of learning. This paper is intended to contribute to critically, self-reflective learning for the community of systems practitioners. These reflections on my questions about participation, ethics, politics of process, and the choices and actions resulting from them may help others to formulate their own. The complexity of systems practice places substantial demands on the researcher, particularly in the case of insider, practitioner research. Nevertheless, the exploration of critical systems approaches to critique boundaries and structure ‘problems’ in the core aspects of higher education in locally meaningful ways should continue. While demanding, it still can work to promote learning about authentic quality.

PEAK COVARIANCE STABILITY OF A RANDOM RICCATI EQUATION ARISING FROM KALMAN FILTERING WITH OBSERVATION LOSSES

We consider the stability of a random Riccati equation with a Markovian binary jump coefficient. More specifically, we are concerned with the boundedness of the solution of a random Riccati difference equation arising from Kalman filtering with measurement losses. A sufficient condition for the peak covariance stability is obtained which has a simpler form and is shown to be less conservative in some cases than a very recent result in existing literature. Furthermore, we show that a known sufficient condition is also necessary when the observability index equals one.     

CONSTRUCTIVE KISSING NUMBERS IN HIGH-DIMENSIONAL SPACES

In the present paper, we focus on constructive spherical codes. By employing algebraic geometry codes, we give an explicit construction of spherical code sequences. By making use of the idea involved in the proof of the Gilbert-Varshamov bound in coding theory, we construct a spherical code sequence in exponential time which meets the best-known asymptotic bound by Shamsiev and Wyner.

一个应用于经济领域的基于知识的可灵活配置的智能蒙特卡洛仿真框架

电子商务的发展,促进了经济贸易的全球化、自由化,加剧了市场的竞争与波动,使得经济模型的适应性受到极大的限制.而经济模型是分析和预测经济发展的基础,为了改善这种限制,我们结合XML与知识技术,建立了一个可配置的智能模型仿真框架.我们也把随机数据库融入该框架中,从而实现了可配置的蒙特卡洛仿真.这样,我们极大地提高了经济模型的适应性、扩展性以及智能性.这种框架可以适用于任何能够运行完全参数化模型的仿真引擎.另外,我们还给出了5种分析仿真结果的方法,以帮助研究人员更好的分析、判断与预测.
