Changes in the body size of UK and US children over the past three decades

Article Abstract:

The main source of using anthropometrics data on the UK child population presented in Childata is Pheasant (1996), where data is estimated using the ratio scaling method, using stature data measured in 1970-71 (Department of Education and Science) DES as the scalar item. The studies reveal that stature increases were less than body weight increases for UK children.

Localize auditory warning pulses

Article Abstract:

The auditory warning pulses are used as an aid in a complex system to maximize the situational awareness of the operator. The identification and testing of a suitable localizable warning pulse is illustrated and the effects of different tonal signatures and component intensity ratio on the perceived urgency of the localizable pulse are examined.

Auditory guidance in a smoke-filled tunnel

Article Abstract:

The efficacy of sound beacons and the escape behavior of people in the road tunnels are tested. The results indicate that the use of directional sound beacons to mark escape exits in tunnels offers a solution to minimize loss of life in the advent of a tunnel fire, especially if the voice message 'exit here' is included.
