The paper presents design and development of an automatic warning system to be used in locations with fluctuating background noises. This adaptive auditory warning system was designed to detect the level of background noises and be able to generate an audio warning with a sound level higher than the background noises. The warning level was automatically(More)
An emergency medical service (EMed) system is proposed as a means to provide timely on-site medical treatment and transportation to the nearest hospital for Bangkok residents. The EMed system consists of a network of 29 fire stations and 4l hospitals in Bangkok linked by the Central Ambulance Dispatcher (CAD). Two models of the EMed system and two levels of(More)
The selection of engineering controls for workplace noise reduction can be formulated as a zero-one nonlinear programming problem which is NP hard. Given a noise control budget and a set of worker locations, the problem objective is to find a combination of feasible engineering controls to minimize a maximum daily noise load. A genetic algorithm (GA) is(More)
