In this article, we address the problem of stochastic motion planning under partial observability, more specifically, how to navigate a mobile robot equipped with continuous range sensors, such as LIDAR. contrast many existing robotic methods, explicitly consider uncertainty state by modeling system partially observable Markov decision process (POMDP). Recent work on general purpose POMDP solve...

Federal and state transportation laws require that a long range transportation plan (LRTP) be developed in urban areas of greater than 50,000 people. The agency responsible for conducting the long range transportation planning process is the Metropolitan Planning Organization (MPO). The Florida Metropolitan Planning Organization Advisory Council (MPOAC) assists individual MPOs in carrying out t...

An "intelligent agent" is a versatile and adaptive computer system. It performs diverse cognitive and physical behaviors in its efforts to achieve multiple goals in a dynamic, uncertain task environment. In this paper, we address the question: How should plans influence the cognitive and physical behavior of intelligent agents? In contrast to the well-known model of plans as executable programs...

We present a long range planning (LRP) system, the Spike Plan Window Scheduler, which has been in use for observations on the Hubble Space Telescope (HST) for the past four years and which is being adapted for the Space Infrared Telescope Facility (SIRTF) and Next Generation Space Telescope (NGST) orbiting astronomical observatories. Due to the relatively underconstrained nature of this domain,...

background and purpose: study skills is one important factor influencing academic achievement of students . we must replace ineffective models and habits of study with more fruitful skills in order to gain better learning. this study investigates the study skills and habits of medical students and their educational achievement. methods: based on a pilot study the sample size was estimates as 40...
