Adaptive Observation Strategy for Dispersion Process Estimation Using Cooperating Mobile Sensors ⋆

Abstract: Efficient online state estimation of dynamic dispersion processes plays an important role in a variety of safety-critical applications. The use of mobile sensor platforms is increasingly considered in this context, but implies the generation of situation-dependent vehicle trajectories providing high information gain in real-time. In this paper, a new adaptive observation strategy is presented combining state estimation based on partial differential equation models of the dispersion process with a model-predictive control approach for multiple cooperating mobile sensors. In a repeating sequential procedure, based on the Ensemble Transform Kalman Filter, the uncertainty of the current estimate is determined and used to find valuable measurement locations. Those serve as target points for the controller providing optimal trajectories subject to the vehicles ’ motion dynamics and cooperation constraints. First promising results regarding accuracy and efficiency were obtained

Acting Hysteria: An Analysis of the Actress and Her Part

This dissertation examines the woman\u27s part in dramatic representation as a hysterical construct and explores the hystericizing effect that the playing of this construct has on the actress. Drawing on feminist psychoanalytic analyses of male psychology and on the historical origins of male-invented female hysteria, this study uses dramatic representation as a model and metaphor for woman\u27s hystericization in Western culture. Charcot\u27s theatricalization of female hysteria through public performances of hysterical acts and the Ophelia as psychological/aesthetic model in British mental asylums are investigated as metaphorical sources for a new definition of female hysteria as a disease of performance, of acting. Case studies of Eleonora Duse, Vivien Leigh and Liv Ullmann are presented as vivid examples of the effects of hysterical parts on the actresses who play them. Feminist strategies are offered for the actress (the woman) in an attempt to explore how one recognizes the hysterical construct at work (at play), and the ideas of feminist theorists such as Luce Irigaray, Helene Cixous and Elin Diamond are explored as tools to help the actress-woman question and subvert the oppressive, maddening effects of the hysterical part. Michel Foucault\u27s investigation of madness and Bertholt Brecht\u27s estranging techniques serve as sources of recognition and strategy for the feminist approach to acting hysteria. Finally, case studies of several hysterical dramatic roles, categorized as (1) pure victims, (2) hysterical minds, (3) modern, analyzed hysterics, (4) actresses, are offered as examples of feminist strategic analysis
