In this paper, we will proposed a hybrid method to generate fuzzy membership function automatically. Particle Swarm Optimization (PSO) is used as optimized algorithm, supplement the performance of fuzzy system. The PSO is able to generate an optimal set of parameter for the membership functions automatic adjustment. Fuzzy control system that automatically backs up a truck to a specified point o...

T his inspection by the Occupational Safety and Health Administration (OSHA) reports on an overexposure to methylene bisphenyl isocyanate (MDI) during the spray application of a protective coating for truck beds. The inspection was conducted at an autobody repair shop and collision center that also operated a spray-on truck bed coating operation. The investigation was initiated as a complaint i...

Studies have suggested that children living close to busy roads may have impaired respiratory health. This study was designed to test the hypothesis that exposure to exhaust from heavy traffic in particular is related to childhood respiratory health. Children attending 24 schools located within 400 m from busy motorways were investigated. The motorways carried between 5,190 and 22,326 trucks pe...

Long-haul truck drivers in the United States experience elevated cardiovascular health risks, possibly due to hypercholesterolemia. The current study has two objectives: 1) to generate a cholesterol profile for U.S. long-haul truck drivers; and 2) to determine the influence of work organization characteristics and sleep quality and duration on cholesterol levels of long-haul truck drivers. Surv...

BACKGROUND Long-distance truck drivers are occupationally susceptible to poor health outcomes. Their patterns of healthcare utilisation and the suitability of healthcare services available to them are not well documented. We report on truck driver healthcare utilisation across South Africa and characterise the client population of the clinics serving them for future service development. METHO...

The state of a non-relativistic gravitational dynamical system is known at any time t if the dynamical rule, i.e. Newton’s equations of motion, can be solved; this requires specification of the gravitational potential. The evolution of a bunch of phase space coordinates w is deterministic, though generally non-linear. We discuss the novel Bayesian non-parametric algorithm CHASSIS that gives pha...

Our long-term goal is one of designing land-based vehicles to provide enhanced uneventerrain locomotion capabilities. In this paper, we examine and evaluate candidate articulated leg-wheel subsystem designs for use in such vehicle systems. The leg-wheel subsystem designs under consideration consist of disk wheels attached to the chassis through an articulated linkage containing multiple lower-p...

This report describes progress in development of an integrated mobile robot system at the Carnegie Mellon Robotics Institute from July 1987 to June 1988. This research was sponsored by the Defense Advanced Research Projects Agency and monitored by the US Army Engineer Topographic Laboratories under contract DACA76-86-C-0019. Our program includes a broad agenda of research in the development of ...

Current SAE practices for evaluating potential improvements in fuel economy on heavy-duty vehicles rely on gravimetric measurements of fuel tanks. However, the recent evolution of portable emissions measurement systems (PEMS) offers an alternative means of evaluating real-world fuel economy that may be faster and more cost effective. This paper provides a direct comparison of these two methods ...

This article shows the application of the decision support system (DSS) Expertchoice© for pick-up truck selection in a colombian shipyard company. The article begins with a description of such decision support systems, followed by a market availability analysis of such systems, and finally presents the application of the DSS Expertchoice© for pick-up truck selection in the company studied.
