results mean age was 41.6 ± 9.2 for the military truck drivers and 43.4 ± 10.9 for commercial truck drivers (p > 0.05). no significant difference between military and commercial drivers was found in terms of driving experience, number of mvcs, binocular va, frequency of color vision defects and cs scores. in contrast, the last ocular examination was significantly earlier in military drivers tha...

Front-end loaders extract sand and gravel (aggregate) from a pit and haul it to a feeder, which releases the aggregate onto a conveyor belt that is connected to a stockpile; the material is subsequently distributed to a processing plant. As mining progresses, the mining frontier moves farther away from the feeder, increasing loader cycle time. In turn, plant managers add loaders to maintain pro...

BACKGROUND AND OBJECTIVES Needlescopic 3-mm instruments induce minimal trauma and produce excellent cosmetic results. A combination of a 3-mm abdominal wall incision and a 5-mm instrument in the abdominal cavity would combine the beneficial features of these two different sizes. METHODS The Percutaneous Surgical System (PSS) (Ethicon EndoSurgery, Galway, Ireland) is a new instrument consistin...

For the case with repetitive driving cycles for a wheel loader the driving cycles parameters affects on the optimal control of the wheel loader is studied. It is clearly seen that average efficiency is not enough and also incorporating driving cycles parameter such as average power, maximum power and amount of recuperative energy will lead to an better estimate on the fuel equivalence factor W .

Motivated by the field sta routing and scheduling problem of an Austrian infrastructure service provider, which involves the planning of subroutes, we study the truck and trailer routing problem (TTRP) [2]. In the TTRP, two types of customers are considered: customers that can be visited by a truck pulling a trailer (denoted as vehicle customers) and customers that can only be visited by a truc...

Current proposals for load-time transformation of Java classes are either dependent on the use of a specific class loader or dependent on a specific JVM implementation. This is not due to an inadequacy of the Java platform but to the wrong choice of the level at which to hook into the Java Class Loader Architecture. JMangler follows a novel approach that ensures both class loader and JVM indepe...

This paper describes the module loader concept. We successfully used this for the development of system software for our mobile robots. The module loader allows for organizing the software in modules. These can be loaded and removed at runtime. We describe how this is done. Additionally we give some examples on how to use the concept. Exemplified on our robot platforms we describe how to design...

The UCF driving simulator was designed to be reconfigurable so that either a commercial truck cab or entire passenger vehicle (Saturn with engine and transmission removed) can be mounted on a motion platform. Several vehicle dynamics models are available for various truck/trailer combinations as well as different passenger vehicles. A study was performed to assess whether there are significant ...

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...
