What brakes the Crab pulsar? [PDF]

open access: yes, 2015
Optical observations provide convincing evidence that the optical phase of the Crab pulsar follows the radio one closely. Since optical data do not depend on dispersion measure variations, they provide a robust and independent confirmation of the radio ...

What can the braking indices tell us about pulsars' nature?

open access: yes, 2006
As a result of observational difficulties, braking indices of only six rotation-powered pulsars are obtained with certainty, all of which are remarkably smaller than the value ($n=3$) expected for pure magnetodipole radiation model.

Analysis of 3k Experiments Applied to Railway Braking: Influence of Contaminants and Train Speed

open access: yesVehicles
The presence of contaminants influences braking efficiency in the railway system because it alters the adhesion at the wheel–rail interface. It is essential to study this phenomenon, as contaminants reduce the friction between wheels and rails, which ...

The contribution of visual information to human brake behaviour [PDF]

open access: yes, 2007
In this study the contribution of visual information to the onset and control of braking in front of a stationary target vehicle was investigated. In a first experiment, participants drove a go-cart along a linear track towards a stationary vehicle, in ...
