Commercial vehicles generally drive at a higher speed on structured expressways, and their center of mass leads to lower rollover threshold greater risk while steering. Therefore, the design lateral trajectory-tracking control strategy for commercial should not only consider accuracy trajectory tracking but also roll stability. Based this objective, fuzzy linear quadratic controller was designe...

This letter constitutes the interim report of the Transportation Research Board Committee for the Study of a Motor Vehicle Rollover Rating System. This committee was convened in response to a request from the Congress asking the U.S. Department of Transportation to fund a study by the National Academy of Sciences on motor vehicle rollover. The main objectives of this report are (1) to present t...

We study the renormalized energy-momentum tensor (EMT) of cosmological scalar fluctuations during the slow-rollover regime for chaotic inflation with a quadratic potential and find that it is characterized by a negative energy density which grows during slow-rollover. We also approach the back-reaction problem as a second-order calculation in perturbation theory finding no evidence that the bac...

In this paper, we present a methodology based on multiple models and switching for real–time estimation of center of gravity (CG) position and rollover prevention in automotive vehicles. Based on a linear vehicle model in which the unknown parameters appear nonlinearly, we propose a novel sequential identification algorithm to determine the vehicle parameters rapidly in real time. The CG height...

This paper studies whether and to what extent transparent disclosure prevents inefficient liquidation arising from rollover risk. We model an illiquid but solvent borrower who can design a public signal about what creditors can recover from forcing liquidation, and what their claims would be worth if the firm survives. We find that the signal structure that minimizes rollover risk never identif...

Background Footwear with a curved sole profile shifts the point of contact between the shoe and floor anteriorly compared to a flat shoe. There have been various reports of changes in ground reaction forces, external joint moments, and (rather inconclusively) muscle activity and energy consumption during walking in this “rollover” footwear [1-6]. The aim of this study was to investigate the eff...

We study a novel aspect of a firm’s capital structure, namely the profile of its debt maturity dates. In a simple theoretical framework we show that the dispersion of debt maturities constitutes an important dimension of capital structure choice, driven by firm characteristics and debt rollover risk. Guided by these results we establish two main empirical results. First, using an exogenous shoc...
