OBJECTIVE To identify risk factors of performance decrement in automobile drivers. METHODS 114 drivers (age <30 years, n=57; age > or =30 years, n=57) who stopped at a rest stop area on a freeway were recruited for the study. They filled out a questionnaire on their journey, sleep/wake patterns and performed a 30-min test on a driving simulator. The test evaluates, by computerized analysis, t...

In order to meet the recently enhanced emission standards at home and abroad, it is necessary to develop the CRDI ECU control algorithm that users can adjust fuel injection timing and amount in response to their needs. Therefore, this study developed the simulator for knocking analysis that enables knocking discrimination and engine balance correction applicable to the ECU exclusive to the indu...

Memory retention of drivers was tested for trafficand traveler-related messages displayed on an in-vehicle information system (IVIS). Three research questions were asked: (a) How does in-vehicle visual message format affect comprehension? (b) How does message format affect memory retention? and (c) What impact does driver age have on recall of in-vehicle visual messages? Nine younger (less than...

Bellcore's Latent Semantic Indexing (LSI) system and HNC's MatchPlus system represent two attempts to model and exploit the inter-relationships among terms to improve information retrieval. Most information retrieval methods depend on exact matches between words in users' queries and words in documents. Typically, documents containing one or more query words are returned to the user. Such metho...

ECG is accustomed for measuring the rate and periodicity of heart pulses, also the chamber’s placement and size, the existence of any injury to the heart, and the consequences of instruments or drugs wont to regulate the heart, example pacemaker. This paper demonstrates the comparison of ECG obtained from the person identification mechanism of automobile drivers beneath several physiological st...

Squamous cell carcinoma of the scrotum is rare and to the best of our knowledge has never been reported from Nigeria. We report on a case thought to be occupation-related in a 42-year old Nigerian taxi driver who had previously been an automobile mechanic and later a long-haul truck driver. He presented with a stage D disease and only palliation was feasible.

Railway level crossings are amongst the most complex of road safety control systems, due to the conflicts between road vehicles and rail infrastructure, trains and train operations. Driver behaviour at railway crossings is the major collision factor. The main objective of the present paper was to evaluate the existing conventional warning devices in relation to driver behaviour. The common conv...
