A new tracking method for estimating motion parameters of a manoeuvring target in a cluttered environment from noisy image sequences is presented. Traditionally, tracking systems have been broadly classified according to (1) moving target with or without manoeuvring, and (2) tracking in a clean (uncluttered) or cluttered environment. The difficulties studied here are those arising from (a) unknown acceleration inducing a randomly updated trajectory, and (b) the disturbance of returns from false alarms or other interfering objects. The probability data association filter (PDAF) is augmented by the semi-Markov process, called the adaptive PDAF, to handle the difficulties. Since the acceleration state applied either by a pilot or by a guidance control system is independent of the appearance of false returns, the treatment of target manoeuvring and false returns are separated into two sub-problems, i.e. the PDAF is applied to govern the disturbance of multiple returns and the semi-Markov process is applied to estimate uncertain accelerations. Three simulation results of variations show small biases from the true trajectory. By comparing with a nearest neighbour standard filter, the proposed tracking system also demonstrates better results.

This study investigated the effects of culture on two industrial vendor selection criteria, price and delivery schedule. Hofstede's dimensions and Chinese Culture Connection's Chinese value survey (CVS), two instruments based on different constructs, were used together to represent the cultural characteristics of industrial buyers from Taiwan and Mainland China. The findings indicated that the CVS was more suitable for detecting cultural differences between these two areas and that masculinity, integration, and moral discipline had significant effects on price awards.
