We propose a novel, vision-based method for robot homing, the problem of computing a route so that a robot can return to its initial “home” position after the execution of an arbitrary “prior” path. The method assumes that the robot tracks visual features in panoramic views of the environment that it acquires as it moves. By exploiting only angular information regarding the tracked features, a ...

Previous research finds a relationship between prejudice against asylum seekers in Australia and negative ideas invoked through political rhetoric; these include perceptions of threat and the acceptance of false beliefs. In recent years, political debate has also seen an increase in hostility towards people smugglers. In this study, we examine whether the expected link between prejudice and per...

Online game is one of the fastest growing industries in Korea. It accounts for 5.8% of the world game market and one third of the world online game market. Korea’s online game market has two-sided market characteristic with very low switching costs. This paper is to study the various characteristics of two-sided market under low switching costs. We empirically investigate network externalities ...

the guidance system. The types of steering commands vary depending on the phase of flight and the type of interceptor. For example, in the boost phase the flight control system may be designed to force the missile to track a desired flight-path angle or attitude. In the midcourse and terminal phases the system may be designed to track acceleration commands to effect an intercept of the target. ...

Numerical state-dependent Riccati equation based integrated guidance-control formulation is developed for an internally actuated missile. The dynamic system under consideration is of tenth order, making it tedious to algebraically manipulate the equations of motion into the state-dependent coefficient form central to the design methodology. A numerical approach based on previous research is dev...
