In 1996, NASA will launch the Mars Pathfinder spacecraft, which will carry an 11 kg rover to explore the immediate vicinity of the lander. To assess the capabilities of the rover, we have constructed a new microrover testbed consisting of the Rocky 3.2 vehicle and an indoor test arena containing Mars analog terrain and overhead cameras for automatic, real-time tracking of the true rover positio...

O are increasingly choosing to implement service-oriented architectures to integrate distributed, loosely coupled applications. These architectures are implemented as services, which typically use XMLbased messaging to communicate between service consumers and service providers across enterprise networks. We propose a scheme for caching fragments of service response messages to improve performa...

Performance of military operators depends on both physical and cognitive aspects. Enhancement of operator performance should therefore address both the body and the brain. This paper focuses on the latter. We provide an extended list of areas where neuroscientific knowledge may be important like training and mental healthcare. We zoom-in on the relevance of neuroergonomics and Brain Machine Int...

A new method to assess noise reduction algorithms with respect to their ability to enhance the perceived quality of speech is presented. Such algorithms consist of both single-microphone systems and multiple microphone systems. Tests of the presented method show a higher correlation with subjective assessments than any other objective system known by the authors. It is believed that this method...

Extensively used in modern gas turbine engines various applications, ranging from aerospace, marine and terrestrial propulsion to power generation pumping, the axial flow turbines have been continuously updated are now capable of high performances reliability. One drawback that has not yet resolved is poor performance at lower- than-nominal regimes. To solve these shortcomings, a new method imp...

The theory of performance feedback views decision makers as problem-solvers seeking to improve performance. By specifying how and when decision makers may instead seek to enhance their self-image by assessing performance as satisfactory, the model presented in this paper specifies boundaries on performance feedback theory’s critical prediction that low performance induces increased search, chan...
