Detection of a period decrease in NN Ser with ULTRACAM: evidence for strong magnetic braking or an unseen companion? [PDF]
We present results of high time resolution photometry of the eclipsing pre-cataclysmic variable NN Ser. We observed 13 primary eclipses of NN Ser using the high-speed CCD camera ULTRACAM and derived times of mid-eclipse, from fitting of light curve ...

Massive star models with magnetic braking
Magnetic fields at the surface of a few early-type stars have been directly detected. These fields have magnitudes between a few hundred G up to a few kG. In one case, evidence of magnetic braking has been found.

Pulsar Braking Indices Revisited [PDF]
Using the standard equation for the slowdown of a neutron star, we derive a formula for the braking index via integration rather than the conventional differentiation. The new formula negates the need to measure the second time derivative of the rotation

Are You Used To It Yet? Braking Performance and Adaptation in a Fixed-base Driving Simulator. [PDF]
During braking-to-stop manoeuvres in a fixed-base driving simulator, the paucity of visual and vestibular cues can lead to driver misperception and produce different patterns of braking response between real and simulated driving.

Gravitational waves from pulsars with measured braking index [PDF]
We study the putative emission of gravitational waves (GWs) in particular for pulsars with measured braking index. We show that the appropriate combination of both GW emission and magnetic dipole brakes can naturally explain the measured braking index ...

Torque Coordination Control during Braking Mode Switch for a Plug-in Hybrid Electric Vehicle
Hybrid vehicles usually have several braking systems, and braking mode switches are significant events during braking. It is difficult to coordinate torque fluctuations caused by mode switches because the dynamic characteristics of braking systems are ...

The influence of Vehicle Dynamics Control System on the Occupant’s Dynamic response during a Vehicle collision [PDF]
This paper aims to apply a vehicle dynamics control system to mitigate a vehicle collision and to study the effects of this systems on the kinematic behaviour of the vehicle's occupant. A unique three-degree-of-freedom vehicle dynamics-crash mathematical

Accelerometer-controlled automatic braking system [PDF]
Braking system, which employs angular accelerometer to control wheel braking and results in low level of tire slip, has been developed and tested. Tests indicate that system is feasible for operations on surfaces of different slipperinesses.

Reduced magnetic braking and the magnetic capture model for the formation of ultra-compact binaries
A binary in which a slightly evolved star starts mass transfer to a neutron star can evolve towards ultra-short orbital periods under the influence of magnetic braking. This is called magnetic capture.

As the traffic intensity on roads increases, the number of road accidents also increases and the situations become more and more complicated. The presented method of reconstruction of preaccidental situations with the purpose of examination of road ...
