Dear editor, Brain perivascular spaces (PVSs) or Virchow-Robin spaces are pial-lined, interstitial fluid-filled structures surrounding the arteries entering brain parenchyma. Enlarged PVSs are radiological manifestation of posttraumatic encephalopathy and a common biomarker of small vessel disease (SVD). Exuberant forms of PVSs are rarely reported. A 55-year-old male truck driver, retired profe...

A 60-year-old truck driver, right-handed, presented with a non-traumatic slow-growing mass on the palm of his left hand. He reported that the mass appeared 3 years prior to consultation, but he failed to seek a medical advice because it did not bother him. The mass slowly grew and started to become painful on palpation. He was referred for excisional biopsy by his family physician because the m...

In this preliminary work, a fleet management problem that occurs in container transportation industry is presented. From the carrier perspective, the present and future operations costs to minimize can be divided in three components: the routing costs, the resource (i.e., driver and truck) assignment costs and the container repositioning costs (i.e., the costs of restoring a given container fle...

Driver fatigue is a significant contributor to motor vehicle accidents and fatalities, although the exact share of those events attributable to fatigue is still uncertain. In 2013, accidents involving heavy trucks killed more than 3,944 people in the United States, with over 80 percent of those killed not in the truck. Numerous factors contribute to driver fatigue among commercial drivers, incl...

The optimal truck configuration for a certain customer is very specific and depends on for what transport mission and in which operating environment the truck is to be used. In addition, the customers normally specify other feature requirements ranging from visual appearance to advanced driver support systems. For this reason, the truck configurations that are made available for the customers a...

Road traffic injuries remain an important public health issue worldwide. More than 1.2 million people die each year due to road fatalities, and 20 to 50 million are estimated to be injured. Moreover, this health burden with epidemic proportions can be considered an increasing problem, particularly in developing countries.1 Alcohol and other drug use is one of the main contributors to the occurr...

This paper proposes a rule-based car-following model to simulate the driver decision process and model the associated vehicle longitudinal action in the car-following regime. In order to analyze individual driver characteristics and extract driving behavior rules, a fuzzy rule based neural network is constructed with the objective of presenting driver action rules under the associated traffic s...

Data associated with over 9000 accidents involving large trucks and combination vehicles during a two-year period on freeways in the greater Los Angeles area are analyzed relative to collision factors, accident severity, and incident duration and lane closures. Relationships between type of collision and accident characteristics are explored using log-linear models. The results point to signifi...

In this research, Ride quality of a three-axle truck is investigated to understand its vibration specifications and influence of it on special load. The truck is Benz 2624, and the load is rather sensitive to vibrations. The system is considered for an off-road duty. Hence, the vehicle is modeled as a nineteen-degree of freedom system and its equations of motion are derived by employing Lagrang...
