Fear of flying is a serious problem that affects millions of individuals. Exposure therapy for fear of flying is an effective therapy technique. However, exposure therapy is also expensive, logistically difficult to arrange, and presents significant problems of patient confidentiality and potential embarrassment. We have developed a virtual airplane for use in fear of flying therapy. Using the ...

Coherent conditional previsions and probabilities are tools to model and quantify uncertainties; they have been investigated in de Finetti [3], [4], Dubins [10] Regazzini [13], [14] and Williams [20]. Separately coherent upper and lower conditional previsions have been introduced in Walley [18], [19] and models of upper and lower conditional previsions have been analysed in Vicig et al. [17] an...

In this paper, we describe and simulate a number of algorithms created to address problems in distributed control systems. Based on tools from matrix theory, algebraic graph theory and control theory, a brief introduction is provided on consensus, rendezvous, and flocking protocols, and Dubins vehicle model. Recent results are then shown by simulating and enhancing various multi-agent dynamic s...

We study a modiied version of the well known Markov-Dubins problem, in which the control is angular acceleration rather than angular velocity. We show that an optimal trajectory cannot contain a junction of a bang-bang and a singular piece, and use results of Zelikin and Borisov to show that there are Pontryagin extremals involving innnite chattering.

The Autonomous Formation Flight (AFF) project at the NASA Dryden Flight Research Center (Edwards, California) investigated performance benefits resulting from formation flight, such as reduced aerodynamic drag and fuel consumption. To obtain data on performance benefits, a trailing F/A-18 airplane flew within the wingtip-shed vortex of a leading F/A-18 airplane. The pilot of the trail airplane ...

Airplane detection has been taking a great interest to researchers in the remote sensing filed. In this paper, we propose a new approach on feature extraction for airplane detection based on sparse coding in high resolution optical remote sensing images. However, direction of airplane in images brings difficulty on feature extraction. We focus on the airplane feature possessing rotation invaria...

Measuring flight characteristics of micro-UAVs is challenging because of their small size and low weight. These constraints prevent the use of conventional onboard measurement systems. The objective of this research was to capture the state information of a radio controlled (RC) airplane using an off-board motion tracking system and to use this state information to study the performance of the ...
