Rollover risk for passenger vehicles is studied using data from six states. The metric that is used is the number of rollovers per single vehicle accident. The analysis is performed with logistic regression and relevant factors such as weather and driver age are controlled for in the model. The use of categorical analysis permits the data to be used on the observation level, preventing the loss...

Protective footwear is necessary for preventing injurious slips and falls in winter conditions. Valid methods for assessing footwear slip resistance on winter surfaces are needed in order to evaluate footwear and outsole designs. The purpose of this study was to utilise a method of testing winter footwear that was ecologically valid in terms of involving actual human testers walking on realisti...

BACKGROUND Studies have reported that women with rheumatoid arthritis (RA) are not wearing NHS supplied therapeutic footwear; therefore it is likely they are wearing footwear sourced through retailers. Previous research gives limited information (largely associated with cosmesis) on people's perceptions on the relationships that exist between retail footwear, well-being and quality of life. Thi...

Background Studies report that women with Rheumatoid Arthritis (RA) are not wearing therapeutic footwear. It is likely they are wearing normal retail footwear. Previous research gives limited information on people’s perceptions on the relationships that exist between retail footwear, well-being and quality of life (QOL). This study aimed to explore these perceptions and to identify the factors ...

Footwear impression evidence has been gaining increasing importance in forensic investigation. The most challenging task for a forensic examiner is to work with highly degraded footwear marks and match them to the most similar footwear print available in the database. Retrieval process from a large database can be made significantly faster if the database footwear prints are clustered beforehan...

The objective of this paper is to develop an analytical framework to representing the ankle-foot kinematics by modelling the foot as a rollover rocker, which cannot only be used as a generic tool for general gait simulation but also allows for case-specific modelling if required. Previously, the rollover models used in gait simulation have often been based on specific functions that have usuall...

Methods Eighty patients with RA were recruited from rheumatology clinics during the summer months from clinics based in Auckland, New Zealand. Clinical characteristics of RA, global function, and foot impairment and disability measures were recorded. Current footwear, footwear characteristics and the factors associated with choice of footwear were identified. Suitability of footwear was recorde...

The analysis updates and expands previous research in which rollover critical events were classified based on a detailed review of approximately 500 police-reported single-vehicle rollover crashes of ESC-equipped vehicles. In order to compare the rollover performance of vehicles with and without ESC for the present study, an additional sample of more than 300 police reports on non-ESC single-ve...

This paper presents a method to design a robust controller for rollover prevention. Several types of controllers for rollover prevention have been proposed in such a way to minimize the lateral acceleration and the roll angle. The rollover prevention capability of these controllers can be enhanced if the controlled vehicle system is robust to the variation of the height of the center of gravity...

As product life cycles become shortened, companies frequently launch new products and discontinue existing ones. Companies with large and complete product lines do not have the extra resources to extend them, so they must plan successful product rollover schemes that launch new products and discard existing ones simultaneously. In previous studies, new product launch schemes and existing produc...
