The DARPA Urban Challenge required robotic vehicles to travel more than 90 km through an urban environment without human intervention and included situations such as stop intersections, traffic merges, parking, and roadblocks. Team VictorTango separated the problem into three parts: base vehicle, perception, and planning. A Ford Escape outfitted with a custom drive-by-wire system and computers ...
background: in-service education is one of the best and major methods to provide, train and improve the performance of the staffs. this study aims to determine the strengths and weaknesses of the virtual trainings from the staffs' perspective of mashhad university of medical sciences. methods: this is a cross-sectional study conducted among staffs from different parts of the therapy depart...
The late Cenozoic geomorphic evolution of Grand Canyon has been infl uenced by three primary tectonic and drainage adjustment events. First, 1 km of relief was produced along the Grand Wash–Wheeler Fault system beginning at 16.5 Ma. Second, the ancestral Colorado River became integrated with the lower Colorado River through Grand Canyon between 5.5 and 6 Ma. Third, the Colorado River was infl u...
Evolutionary Robotics is a field that “aims to apply evolutionary computation techniques to evolve the overall design or controllers, or both, for real and simulated autonomous robots” (Vargas et al., 2014). This approach is “useful both for investigating the design space of robotic applications and for testing scientific hypotheses of biological mechanisms and processes” (Floreano et al., 2008...
The design of a virtual piano action composed of a keyboard of motorized keys and a realtime mechanical system simulation is presented. Using this simulator, we have re-created certain aspects of the feel of the grand piano by numerically integrating the equations of motion of a simpli ed piano action in real time in a human-in-the-loop simulation scheme. In this paper, the simulation of the re...
The requirements of grand challenge problems and the deployment of gigabit networks makes the network computing framework an attractive and cost effective computing environment with which to interconnect geographically distributed processing and storage resources. Our project, Virtual Distributed Computing Environment (VDCE), provides a problem-solving environment for high-performance distribut...
Walker manifolds of signature (2, 2) have been used by many authors to provide examples of Osserman and of conformal Osserman manifolds of signature (2, 2). We study questions of geodesic completeness and Ricci blowup in this context.
The U.S. National Academy of Engineering’s Grand Challenges for Engineering report has received a great deal of attention from legislators, policymakers, and educators, but what does it entail for social justice considerations in engineering? This article situates the Grand Challenges report as a cultural artifact of the engineering profession—an artifact that works to reinforce engineering’s p...
In this position paper, I introduce five grand challenges in the development of networked digital games. While this list is not intended to be exhaustive, I argue that these challenges are significant in that they are holding back the development of the next generation of innovative games.
