In this paper the Multiple Hypothesis Tracking with group tracking is applied to tracking targets in video sequences. The width/height ratio is used as a target feature to help in target/detection association. Group tracking is tested in real video sequences (PETS 2001) and shows that is possible to keep linked the otherwise interrupted tracks.

Shared responsibilities such as mentoring, instruction, learner monitoring and classroom management enable the peers to observe, review, reflect on and learn from the overall practical professional expertise of one another through collegial instruction experience. The present exploratory case study has The present exploratory case study has attempted to study collegial teaching as an innovative...

We show that for every n there are two simple curves on the torus intersecting at least n times without the two curves folding or spiralling with respect to each other. On the other hand, two simple curves in a punctured plane that intersect at least n times (and do not create any empty bigons) must either form a spiral of depth d or a fold of width cn/(d + 1) − 1, where c only depends on the n...

The prevalence and characteristics of mentorship among junior faculty in clinician-scientist and clinician-educator tracks were evaluated. Comprehensive improvement strategies are needed.

Coursebooks are normally written to contain information, instruction, exposure, and activities that learn- ers at a particular level need to enhance their communicative competence in the target language. Howev- er, many global course books make attempts to include content, topics, and texts that do not disadvantage any learner around the world. That is why global course books normally do ...

The water cycle in the western United States changed dramatically over glacial cycles. In the past 20,000 years, higher precipitation caused desert lakes to form which have since dried out. Higher glacial precipitation has been hypothesized to result from a southward shift of Pacific winter storm tracks. We compared Pacific Ocean data to lake levels from the interior west and found that Great B...

The objective of this paper is to identify the incentives and barriers to marriage among cohabiting women, especially disadvantaged mothers who are targets of welfare reform. We use the newly released cohabitation data from the National Longitudinal Survey of Youth (1979-2000), which tracks the partners of cohabiting women across survey waves. Our results support several conclusions. First, coh...

This study was designed to investigate the effects of three countermeasures--landscaping, building a fence and prohibitive signs--on the frequency of trespassing, which in this case means crossing the track at places where it is forbidden. At each location the official route was no more than 300 m away. The main results showed that the effect of each countermeasure on the frequency of trespassi...
