Exposure to hydrofluoric acid (HF) causes corrosive chemical burns and potentially fatal systemic toxicity. Car and truck wash cleaning products, rust removers, and aluminum brighteners often contain HF because it is efficient in breaking down roadway matter. The death of a truck wash worker from ingestion of an HF-based wash product and 48 occupational HF burn cases associated with car and tru...

Nobody denies that the input plays an important role in language acquisition, but the issue as to whether the input is sufficient to drive language learning is still a matter of debate. In this paper we examine children’s acquisition of synthetic compounds in English and Dutch. Despite having necessarily different input, Dutchand English-speaking children produce the same set of non-adult forms...

One important source of variability in the performance and success of products designed for use by people is the people themselves. In many cases, the acceptability of the design is affected more by the variability in the human users than by the variability attributable to the hardware from which the product is constructed. Designing for human variability as an inherent part of the product opti...

The U.S. Truck Driver Scheduling Problem (US-TDSP) is the problem of visiting a sequence of λ locations within given time windows in such a way that driving and working activities of truck drivers comply with U.S. hours of service regulations. In the case of single time windows it is known that the US-TDSP can be solved in O(λ) time. In this paper we present a scheduling method for the US-TDSP ...

This thesis presents a compilation of methods to consider when mapping steering functions and results as vehicle dimensions change. It is concluded that some final tuning inevitably will be required as major changes are performed. It is however possible to create qualified starting points using a set of simple rules as presented. Considered properties are steering wheel size, wheelbase, steerin...

1 The traffic flow heterogeneity caused by the different car-following dynamics among the different types 2 of vehicles has drawn increasing attention recently. This paper explores the characteristics of the four 3 types of car-truck car-following combinations, car-following-car (CC), car-following-truck (CT), truck4 following-car (TC) and truck-following-truck (TT), and their impacts on traffi...

During the design and development of truck cabins, the safety of the driver and the front seat passenger in an accident is an important task and should be considered. The cab must be designed in such a way that in an accident a sufficient survival space is guaranteed. The aim of this study is to investigate the behavior of Iran Khodro (IKCO) 2624 truck subjected to a complex crash test accor...

Field operational testing for the study of driver behavior requires extensive preparation and precaution measures to limit subjects risk exposure during experiment. Moreover, inherent variability in testing conditions may introduce error in the experiment results. Alternatively, a driving simulator offers the ability to replicate driving situations in a safe and repeatable experimental environm...
