Estimations of scattering parameters, such as average scatterer diameter, from rf signals backscattered from random media (tissues) are made from the frequency dependence of the rf signal. The frequency dependence of the rf signal backscattered from the medium is seen in the normalized power spectrum. The normalized power spectrum is found by taking the squared magnitude of the Fourier transfor...

This paper presents a new algorithm for detection and compensation of backlight images. The proposed technique attacks the weakness of the conventional backlight image processing methods such as over-saturation, losing contrast and so on. The proposed algorithm consists of two operation phases: detection and compensation phases. In the detection phase, we use the spatial position characteristic...

Weight loss from exercise-induced energy deficits is usually less than expected. The objective of this systematic review was to investigate predictors of energy compensation, which is defined as body energy changes (fat mass and fat-free mass) over the total amount of exercise energy expenditure. A search was conducted in multiple databases without date limits. Of 4745 studies found, 61 were in...

BACKGROUND Hairdressers are one of the largest occupational groups attending our Occupational Dermatology Clinic. However, few seek workers' compensation for their occupational dermatitis. OBJECTIVES To retrospectively analyse and compare workers' compensation claims data and diagnosed disease data for occupational contact dermatitis in hairdressers from 1993 to 2009, for the state of Victori...

Hong Kong is notorious for her high construction accidents rates. Although the accidents rate has dropped from 350 per 1000 workers in mid 1980 to 60 per 1000 workers in 2007, it still accounted for nearly one-fifth of all the industrial accidents in Hong Kong. Contractors were economically pressed and battered by exorbitant compensation over the years. This paper presents a comprehensive study...
