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...

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...

Using payday-lender administrative data matched to borrower credit attributes from a national credit bureau, I find that borrowers who engage in protracted refinancing (“rollover”) activity have better financial outcomes (measured by changes in credit scores) than consumers whose borrowing is limited to shorter periods. These results are robust to an alternative definition of a “rollover” that ...

In this paper, the consequences of filled volume on the transient lateral dynamic and stabilities boundaries displacement of an articulated vehicle carrying liquid is investigated. First, a sixteen-degrees-of-freedom nonlinear dynamic model of an articulated vehicle is developed then, using TruckSim software the model is validated. Next, the dynamic interaction of the fluid cargo with the vehic...

This study investigates whether temporally jittered stimuli will produce performance-intensity, phonetically balanced (PI-PB) rollover in young adults with normal hearing. Although not yet explicitly stated in the literature, there is clinical and theoretical evidence to suggest that PI-PB rollover, such as that found in cases of acoustic neuroma, is caused by neural dyssynchrony in the auditor...

The paper addresses the problem of vehicle rollover avoidance using reference governors applied to modify the driver steering input in vehicles with an active steering system. Several reference governor designs are presented and tested with a detailed nonlinear simulation model. The vehicle dynamics are highly nonlinear for large steering angles, including the conditions where the vehicle appro...

Mobile manipulators operating in eld environments are susceptible to dangerous and costly rollover or tipover instabilities, particularly when operating over uneven terrain or when exerting large forces or moments. By monitoring the static and dynamic tipover stability margins of a mobile manipulator it is possible to predict such tipovers and take appropriate actions to prevent the tipover fro...
