This paper presents a virtual force approach for cooperative standoff tracking of a stationary target using multiple robots. Each robot is governed by virtual forces, namely, virtual centripetal force, virtual spring forces and virtual drag forces. The virtual centripetal force counteracts the effect of the centrifugal force and ensures each robot orbit the target. The virtual springs make the orbiting...
This survey study explored the effects of different types of work-family conflict on work/family satisfaction and subjective well-being(SWB). We distinguished work-family conflict into six types based both on the directions (work-interference-family, WIF; family-interference-work, FIW) and the forms (time based, strain based and behavior based conflict) of conflict. We also testified the moderating...
As more and more mission critical services emerge on the Internet, there is a growing demand for the Internet to provide stringent service availability and reliability. More and more domains adopt multi-homed connection to expect increasing reliability. But the de facto inter-domain protocol - BGP spends a long period to converge to another stable state when one of the links of multi-homed domain...
Maintaining connectivity is a key responsibility of any routing system, but successfully carrying it out can be challenging, especially for inter-domain paths. Many measurements indicate the links failures are fairly common in the Internet. During the period of failures, some destination would be unreachable and the corresponding services unavailable. Shrinking the convergence time window to improve...
As more and more mission critical services emerge on the Internet, there is a growing demand for the Internet to provide stringent service availability and reliability. Many studies show that inter-domain links fail as frequently as intra-domain links. The performance of those services in the present of failures would be greatly deteriorated. In this paper, we propose a scalable and resilient inter-domain...
