A second major effort is currently underway toward the development of vehicles with autonomous capabilities. The Autonomous Land Vehicle and Advanced Ground Vehicle Technology programs highlighted the first efforts in autonomous vehicles. The second push is fueled by the Office of the Secretary of Defense's (OSD) Unmanned Ground Vehicle (UGV) program. The Surrogate Teleoperated Vehicle and Demo...

The collinear relative equilibrium solutions are among the few explicitly known periodic solutions of the Newtonian three-body problem. When the energy and angular momentum constants are varied slightly these unstable periodic orbits become normally hyperbolic invariant spheres whose stable and unstable manifolds form separatrices in the integral manifolds. The goal of this paper is to construc...

this paper analyses and compares the performances of business-to-business e-commerce data quality and service quality among the use of the ‘push’ and ‘pull’ models. rosettanet’s original partner interface processes use the ‘push’ model which suffers from data redundancy when the volume of business-to-business transaction increases. however, when the ‘pull’ model is used, although it reduces dat...

To instill confidence in the public regarding the investigation process, it is essential that an investigating agency be independent and free from any conflicts of interest when conducting an investigation. As such, the TSB is an independent agency, separate from other Canadian government agencies and departments. TSB final reports and safety communications are not subject to government revisio...

Complex design problems require more knowledge than any single person possesses because the knowledge relevant to a problem is usually distributed among stakeholders. Bringing different and often controversial points of view together to create a shared understanding among these stakeholders can lead to new insights, new ideas, and new artifacts. New media that allow owners of problems to contri...

1 Introduction The ankle delivers about half of the total mechanical work during walking. Lower-limb amputees using conventional passive-elastic prostheses experience 20 to 30% higher metabolic cost than able-bodied individuals, perhaps because these prostheses do not provide net positive work during the course of a step [1]. To address this problem, companies are developing battery-powered pro...

Today, often ankle’s active prosthesis is used for transtibial amputated people’s walking, because these prostheses have some advantages such as increasing power and decreasing metabolism. In most of active prosthesis in order to create a movement or increase the force at the push-off, electrical actuators are used like a motor. In cases where a higher-power motor is necessary, the capacity, we...

The electron-positron collider CESR was constructed as an upgrade to the Cornell Electron Synchrotron in the late 1970’s, originally designed to operate at 16 GeV center of mass with a maximum luminosity of 1x10 cm-sec. [1] The parameter list specified a single 100 mA (1.5x10 e-) bunch in each beam and beam-beam parameters of 0.06 in each plane. The fortuitous discovery of the Upsilon family of...
