The common goal of all repository concepts is the safety in the post closure phase of a repository. But by this the safety of the operational staff and the today public should not take a back seat. This must be an emancipated goal beside the safety in the post closure phase. A keyword in the frame post closure safety is the robustness of the repository concept. The same keyword could be used in...

–This paper presents an investigation into the effectiveness of controllable magnetorheological (MR) damper for a semi-acive vehicle model with passenger seat. Mathematical model has been experimentally developed for controller design using Choi et al. model. A quarter vehicle model has been employed for system performance evaluation via Matlab through numerical simulation. System behaviour rel...

To protect the driver of off-highway dump trucks from the harmful vibration, this paper presents the comparison results to determine the optimal damping of the seat system by different optimization design plans. Three optimization schemes are considered including individually optimizing the damping of the cushion, individually optimizing the damping of the seat suspension, and integrately optim...

OBJECTIVE The Lower Anchor and Tethers for CHildren (LATCH) system was introduced in vehicles made after September 1, 2002 and intended to make installation of rear and forward-facing child safety seats easier. Due to the lack of rear impact testing of RFCRS required per the Federal Motor Vehicle Safety Standards (FMVSS), the purpose of this study was to explore the effects, if any, of installa...

Vision systems within vehicles offer new opportunities in the automobile industry. The detection and classification of passenger and driver seat occupancy open up new ways to improve the safety and comfort of the passengers. In this paper we present results of a stereo system designed for the observation of the cockpit scene in order to provide information about the passenger presence and locat...

It is generally accepted today that the cervical spine of a car occupant who is involved in a low-speed rear end impact may suffer from soft tissue neck injuries leading to long-term impairment. Therefore, to assess the risk of sustaining such injuries is a major issue in traffic safety, and various neck injury criteria are being discussed for this purpose. In this study a new candidate for suc...

this paper deals with the ejection system that can be implemented in a civil aircraft. It is important for an aircraft to have an ejection seat in case the plane meets an accident in a battle or during test flight and the pilot has to bail out to save his or her life. The mechanism involves lifting of the pilot to a safe distance away from the aircraft and then deploying the parachute. As there...

Objective—To evaluate the feasibility, acceptability, and eVectiveness of an injury prevention program delivered by school based home visitors to the families of low income children attending preschool enrichment programs in Washington State. Study sample—The families of children attending preschool Head Start programs in two regions were eligible. A total of 213 families (77.8% of those eligib...
