Mixed control of uncertain jumping time-delay systems     

Magdi S. Mahmoud  Fouad M. AL-Sunni  Yan Shi   《Journal of The Franklin Institute》2008,345(5):536-552

In this paper, we investigate a class of linear continuous-time systems with Markovian jump parameters. An integral part of the system dynamics is a delayed state with time-varying and bounded delays. The jumping parameters are modeled as a continuous-time, discrete-state Markov process. Employing norm-bounded parametric uncertainties and utilizing the second-method of Lyapunov, we examine the problem of designing a mixed controller which minimizes a quadratic performance measure while satisfying a prescribed -norm bound on the closed-loop system. It is established that sufficient conditions for the existence of the mixed controller and the associated performance upper bound could be cast in the form of linear matrix inequalities.  相似文献

The multi-paradigmatic character of contemporary educational action research: a promising perspective or an underlying threat?     

Eleni Katsarou 《Educational Action Research》2017,25(5):673-686

From the very first moment action research started to be used in the social research field until now, it has presented significant variations. Action research looks like a mosaic of theoretical and methodological approaches, named differently from time to time and/or from place to place: for example, practitioner inquiry, practitioner research, teacher research, participatory action research, and so forth. The basic aims of this article are to find the reasons for this and to discuss the implications of the phenomenon. Starting with the first issue, we could ask ourselves: why do we today find so many and considerable variations in action research approaches in the literature? The evident reason is because action research draws upon many theoretical paradigms that – in some circumstances – are not only different, but also contradict each other. Hammersley states characteristically that action research draws upon positivism, pragmatism, hermeneutics, critical theory and postmodernism! After such claims, we can easily wonder: how can such a multi-paradigmatic approach compose cohesive methodological proposals? We can also pose another crucial question: although we can easily understand that this multi-paradigmatic nature is a real advantage which gives action research a pluralistic essence, is it really ‘a strong indicator of the power of action research to reinvent itself according to local needs’ as Somekh stated, or might it at the same time conceal serious risks?  相似文献   

College/University Counseling Centers Supporting Study Away: Challenges and Opportunities     

Charles C. Morse  Janet Dee Spoltore  Paul Galvinhill 《Journal of College Student Psychotherapy》2017,31(4):325-335

Research points to significant numbers of students on college campuses experiencing mental health distress and an ever increasing number of college students who are choosing to make an off-campus educational experience a part of their college careers. When we consider both of these trends together, it is quite apparent that a significant number of students with mental health concerns will spend periods of time studying away from campus, with converging concerns among college mental health and study away professionals about how to best support these students. This article seeks to outline both challenges and opportunities inherent in the collaboration between campus professionals in supporting students with mental health issues before and during their study away experiences.  相似文献
