Many existing Wireless Sensor Network (WSN) synchronisation protocols have demonstrated microsecond-level accuracy is achievable. Furthermore, sub-microsecond-level accuracy has recently been reported, although rather sophisticated, relatively bulky and custom-designed hardware were needed. This paper addresses a fundamental problem in WSN synchronisation: is there a more elegant way to achieve precise...
Accurate measurements of athletes' stride parameters, such as stride/step length, stride/step frequency, stance times and foot contact times are important to coaching support and biomechanics research in sprinting. Existing stride parameter monitoring approaches are either expensive, or insufficiently accurate, or not suitable for supporting daily training sessions. This paper investigates the use...
Stride-related parameters of sprinters, such as split times (i.e. which is speed-related), foot contact times, stance times, stride/step length, and stride/step frequency, etc. are important factors which affect athletes' performances. Traditionally, this information is captured by biomechanics researchers and coaches using optical-based systems. However, these systems are expensive, time consuming...
To consider time varying system operating conditions and operating reserve units, the online short-term reliability of a power system is investigated. Real-time system reliability based on the online operation data provided by the SCADA/EMS/WAMS is assessed using time- dependent state probabilities of components. Considering both speed and accuracy requirements, a fast sorting technique (FST) is proposed...
