Master narratives as “colonial propaganda” and counternarratives as “refusal”: How African Australians reimagine racial dignity in Australia

American Journal of Community Psychology, EarlyView.
Abstract This paper utilizes the concept of “colonial master narratives” to examine how racial propaganda is mobilized in the Australian imaginary to “flatten” the stories of Blac/k people and how African Australians deploy counternarratives to reject these racialized projections.

Freedom dreaming of migrant justice: Critical reflections on counterspaces and institutional violence in the university

American Journal of Community Psychology, EarlyView.
Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

Place‐based risk: Examining relationships between adolescent perceptions of community risk factors and adolescent substance use across geographic contexts

American Journal of Community Psychology, EarlyView.
Abstract Mixed evidence for the influence of structural and social factors on adolescent substance use behaviors exists across the rural–urban continuum. Therefore, this study explores how adolescent perceptions of structural and social community risk factors are associated with lifetime and past 30‐day use of alcohol, marijuana, cigarettes, and ...

Passive actuators’ fault tolerant control for affine nonlinear systems

IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2008
Abstract In this paper we consider the problem of passive fault tolerant control for nonlinear affine systems with actuators faults. We treat two types of faults; additive and loss of effectiveness faults. In each case we propose a Lyapunov-based feedback controller that ensures the local uniform asymptotic (exponential) stability of the faulty ...

Design of passive fault tolerant control of a process system

The 27th Chinese Control and Decision Conference (2015 CCDC), 2015
Fault tolerant control strategies are classified into active tolerant control and passive tolerant control. When an efficient fault diagnosis procedure is difficult to be obtained, a passive tolerant control strategy is a realistic choice. This paper introduces an example of passive tolerant control system design which take into account the priori ...

Fault-tolerant control systems: A comparative study between active and passive approaches

Annual Reviews in Control, 2012
Abstract This paper demystifies active and passive fault-tolerant control systems (FTCSs) by examining the similarities and differences between these two approaches from both philosophical and practical points of view. Even though the control objectives of both approaches are the same, each method uses its own unique ways to achieve the objectives ...

A simultaneous stabilization approach to (passive) fault tolerant control

Proceedings of the 2004 American Control Conference, 2004
This paper discusses the problem of designing fault tolerant compensators that stabilize a given system both in the nominal situation, as well as in the situation where one of the sensors or one of the actuators has failed. It is shown that such compensators always exist, provided that the system is detectable from each output and that it is ...

Experimental passive fault tolerant control for gyroscope system

21st Mediterranean Conference on Control and Automation, 2013
This paper is dedicated to the passive fault tolerant control of moment gyroscope. Erroneous sensor reading and actuator faults reduce the performance and may even cause the instability. As a matter of fact, the control of the gyroscope system when these drawbacks are occurred often requires the fault tolerant control design.
