Carbon-Oxygen White Dwarfs Accreting CO-Rich Matter I: A Comparison Between Rotating and Non-Rotating Models [PDF]

open access: yes, 2002
We investigate the lifting effect of rotation on the thermal evolution of CO WDs accreting CO-rich matter. We find that rotation induces the cooling of the accreting star so that the delivered gravitational energy causes a greater expansion with respect ...

A New Stopping Sight Distance Model and Fuzzy Reliability Analysis Comparison

open access: yesIEEE Access, 2022
Aiming at the problem that the existing stopping sight distance model is out of sync with the development of the times, this paper puts forward a new stopping sight distance model considering the fuzziness and randomness of design parameters, and deduces

Enhancement of Vehicle Safety and Improving Vehicle Yaw Behaviour Due to Offset Collisions Using Vehicle Dynamics [PDF]

open access: yes, 2012
This study aims to optimise Vehicle Dynamic Control Systems (VDCS) in offset impact for vehicle collision mitigation. A proposed unique 3-D full-car mathematical model is developed and solved numerically to carry out this analysis. In this model, vehicle

Evaluation of a sudden brake warning system: Effect on the response time of the following driver [PDF]

open access: yes, 2010
This study used a video-based braking simulation dual task to carry out a preliminary evaluation of the effect of a sudden brake warning system (SBWS) in a leading passenger vehicle on the response time of the following driver.

A New Model of Stopping Sight Distance of Curve Braking Based on Vehicle Dynamics

open access: yesDiscrete Dynamics in Nature and Society, 2016
Compared with straight-line braking, cornering brake has longer braking distance and poorer stability. Therefore, drivers are more prone to making mistakes. The braking process and the dynamics of vehicles in emergency situations on curves were analyzed.

Potential benefits of an adaptive forward collision warning system [PDF]

open access: yes, 2008
Forward collision warning (FCW) systems can reduce rear-end vehicle collisions. However, if the presentation of warnings is perceived as mistimed, trust in the system is diminished and drivers become less likely to respond appropriately.

Transport energy consumption in mountainous roads. A comparative case study for internal combustion engines and electric vehicles in Andorra [PDF]

open access: yes, 2015
This paper analyses transport energy consumption of conventional and electric vehicles in mountainous roads. A standard round trip in Andorra has been modelled in order to characterise vehicle dynamics in hilly regions.

A Proper Motion for the Pulsar Wind Nebula G359.23-0.82, "the Mouse," Associated with the Energetic Radio Pulsar J1747-2958 [PDF]

open access: yes, 2009
The "Mouse" (PWN G359.23-0.82) is a spectacular bow shock pulsar wind nebula, powered by the radio pulsar J1747-2958. The pulsar and its nebula are presumed to have a high space velocity, but their proper motions have not been directly measured.

Stellar Forensics II: Millisecond Pulsar Binaries [PDF]

open access: yes, 1997
We use the grid of models described in paper~I to analyse those millisecond pulsar binaries whose secondaries have been studied optically. In particular, we find cooling ages for these binary systems that range from $< 1 \rm Gyr$ to $\sim \rm 15 Gyr ...
