DESCRIPTION:Research: Modeling the Model Athlete : Automatic Coaching of R
 owing Technique\, Simon Fothergill\n\n\nWatching athletes allows coaches t
 o provide both vital feedback on how well they are performing and on ways 
 to improve their technique without causing or aggravating injuries. The th
 oroughness and accuracy of this traditional observation method are limited
  by human ability and availability. Supplementing coaches with sensor syst
 ems that generate accurate feedback on any technical aspect of the perform
 ance gives athletes a fall back if they do not have enough confidence in t
 heir coach's assessment.\n\nA system is presented to model the quality of 
 arbitrary aspects of rowing technique found to be inconsistently well perf
 ormed by a set of novice rowers when using an ergometer. Using only the mo
 tion of the handle\, tracked using a high-fidelity motion capture system\,
  a coach trains the system with their idea of the skill-level exhibited du
 ring each performance\, by labeling example\ntrajectories. Misclassificati
 on of unseen performances is encouragingly low\, even for unknown performe
 rs.\n\nResearch: Efficient Medium Access Control\, Bogdan Roman\n\nWe are 
 rapidly moving towards a wireless world. Networks will only grow in size a
 long with the number of active users. This\, combined with the increasing 
 demand for multimedia applications and\, many times\, mobility make medium
  access control a high priority for efficient communication. This talk wil
 l present a collection of techniques that are applicable to both wireless 
 and wired networks and which are able to substantially improve several asp
 ects such as raw performance\, scalability\, guaranteed Quality of Service
 \, topology independence and others. Some of the techniques presented can 
 also be for randomized leader election\, channel initialization or in coop
 erative networks.
