OBJECTIVE To describe traumatic brain injury (TBI) among injured roadway users. Aim 1 assessed the association of age, gender, alcohol/drug use, safety equipment use, type of roadway user, metropolitan area, and primary payer with motor vehicle-related TBI outcome. Aim 2 assessed the relationship of motor vehicle-related TBI and risk/protective factors with medical and economic outcomes. METH...

Earthquakes are among those natural hazards which may lead to disruption in the function of arterial traffic routes. Road networks are particularly vulnerable, due to their geographical dispersion, extensive functions and structural reliance on favourable geophysical conditions. Traffic functionality after a natural disaster and the repair/rehabilitation cost of roads are crucial considerations...

Pricing of roadways opens doors for infrastructure financing, and congestion pricing seeks to address inefficiencies in roadway operations. This paper takes a cost-benefit approach to illuminate how the costs of infrastructure can be offset via pricing, while ascertaining the welfare impacts of flat-toll, standard congestion pricing, and credit-based congestion pricing policies. While most road...

In this paper I analyze the interaction between sound and the visual arts as well as its development through the acoustic space and time. In other words, I am trying to understand the aesthetic implications of the sound sculpture and sound installation disciplines. Nevertheless, in order to understand the main characteristics of this relatively new media, we need first to consider some importan...

Users often install applications from untrusted sources. Alcatraz is a system that provides isolation of a system from potentially untrustworthy user programs. However, we find performance and functionality concerns with Alcatraz. Nevertheless, Alcatraz demonstrates the feasibility of one-way isolation of user programs. During a port of Alcatraz to a modern commodity operating system, Mac OS X,...

PURPOSE: To develop a method for direct measurement, using anatomic specimens, of the precision of MR-guided stereotaxic location and to describe its application to a 1.5-T MR unit with a Leksell stereotaxic frame. METHODS: Small pieces of gel foam ( 1 X 1 X 1 mm), soaked in gadopentetate dimeglumine, were stereotaxically introduced into formalin-fixed human heads using a Leksell D (three exper...

Cultured Atlantic salmon (Salmo salar L.) may be introduced into natural systems intentionally or accidentally. As smolts or post-smolts, they move to the feeding areas of wild salmon in the North Atlantic Ocean. As maturing fish, they return to the area of release and enter rivers to spawn. Lack of juvenile river experience is the prime reason why cultured salmon often enter fresh water later ...

In recent years, with the extension of coal mine at depth, rock bursts are more and frequent. Therefore, research roadway support pressure relief has become key to prevent burst. this paper, primary high strength hydraulic fracturing measures studied analysed. The emphasizes matching characteristics materials, strengthen protection active roadway, realize an integrated system. Considering stron...

OBJECTIVES Few low income countries have emergency medical services to provide prehospital medical care and transport to road traffic crash casualties. In Ghana most roadway casualties receive care and transport to the hospital from taxi, bus, or truck drivers. This study reports the methods used to devise a model for prehospital trauma training for commercial drivers in Ghana. METHODS Over 3...

In this paper, we investigate predictive control approaches to the problem of roadway departure prevention via steering and braking. We assume a sensing infrastructure detecting road geometry and consider a two layers architecture consisting of a threat assessment and an intervention layer. In particular, the upper threat assessment layer detects the risk of roadway departure or vehicle instabi...
