Beam-pushed propulsion systems, such as solarlaser-, or microwavepushed sails, allow the possibility of fuel-free propulsion in space. This makes possible missions of extremely high delta=V, potentially as high as 30,000 km/sec (0.1c), which is required for an fly-by mission to a nearby star. This project analyzed the potential use of dielectric thin films for solar and laser sails. The advanta...

One of the major challenges in cloud computing is the development of a service-level agreement (SLA) negotiation framework using an intelligent third-party broker negotiation strategy. Current frameworks exploit various negotiation strategies using game theoretic, heuristic, and argumentation-based approaches for obtaining optimal negotiation with a better success rate (negotiation commitment)....

Abstract Negotiators are not always rational. Prior studies have found that negotiators tend to be overconfident about their ability win and underestimate the possibility of negotiation failure. This biased judgment may lead irrational evaluation miss chance settle. It is argued handle a respective perception risk failing. The failure therefore has pivotal influence on outcome warrant deeper co...

In this paper, we prove some qualitative properties of pushed fronts for the periodic reaction-diffusion-equation with general monostable nonlinearities. Especially, exponential behavior when they are approaching their unstable state. The proof also allows us to get pulsating speed c larger than minimal speed. Through behavior, finally stability fronts.
