Motivated by the ideas of multi-scale representations in the wavelet theory, in the new model, a Gaussian process is represented at a scale by a linear basis that is composed of a scale function and its different translations. Finally the distribution of the targets of the given samples can be obtained at different scales. Compared with the standard Gaussian Processes (GP) model, the MGP model can control its complexity conveniently just by adjusting the scale pa-rameter. So it can trade-off the generalization ability and the empirical risk rapidly. Experiments verify the fea-sibility of the MGP model, and exhibit that its performance is superior to the GP model if appropriate scales are chosen.展开更多

The test has also been utilized in academia to enhance instructor＇s knowledge of the different learning styles and thus allows them to develop strategies to increase students＇ learning. The test is a forced-choice self-reporting exam comprised of 126 questions. Based on Jung＇s theory of personality type, the test seeks to categorize personality types into 16 discrete groups based on the four preference poles （Myers, 1962）. The poles are based on the preference for： （1） introversion （I） or extroversion （E）; （2） sensing （S） or intuition （N）; （3） thinking （T） or feeling （F）; and （4）judging （J） or perception （P）. Laribee （1994） studied American accounting students and found that certain personality traits were over represented in upper-level accounting courses, while Macdaid, McCaulley, and Kainz （1986） found that the same personality trait groups were over-represented in the profession. Oswick and Barber （1998）, however, found no significant relationship between the grade earned in an introductory accounting course and the personality traits as identified by the MBTI with 344 UK-based accounting students. This study investigates the relationship between a student＇s academic success in a financial accounting principles course and the MBTI personality type indicators. The type distribution of 59 historically black colleges and universities＇ （HBCU） business administration majors was analyzed and separated into two groups. The groups were then tested to determine if there was a significant difference in the mean grade of the groups in accounting principles.展开更多

The theoretical study consists on the establishment, through mass and energy balances, of a mathematical model to control the exiting temperature of the heating fluid as well as the temperatures of the absorber and the glass. The experimental level investigates the influence of the solar absorber tube diameter on the performances of the driving device. Several experiments were made in order to know the possibility to reach temperatures being able to ensure for example the ammonia vaporization in the generator of a solar absorption refrigeration system. These experiments were carried out under various operating and climatic conditions. The results are presented and discussed.展开更多
