Sliding Mode Control of Vehicle Equipped with Brake-by-Wire System considering Braking Comfort

open access: yesShock and Vibration, 2020
For passengers, the most common feeling during running on the bumpy road is continuous vertical discomfort, and when the vehicle is braking, especially the emergency braking, the instantaneous inertia of the vehicle can also cause a strong discomfort of ...

Magnetic braking in young late-type stars: the effect of polar spots

open access: yes, 2007
The concentration of magnetic flux near the poles of rapidly rotating cool stars has been recently proposed as an alternative mechanism to dynamo saturation in order to explain the saturation of angular momentum loss.

The braking index of millisecond magnetars [PDF]

open access: yes, 2017
We make the first measurement of the braking index $n$ of two putative millisecond magnetars born in short gamma-ray bursts. We measure $n=2.9\pm0.1$ and $n=2.6\pm0.1$ for millisecond magnetars born in GRB 130603B and GRB 140903A respectively.

About Braking of Wheeled Vehicle Equipped with Automated Brake Control System

open access: yesНаука и техника, 2022
The paper proposes a method for determining a vehicle stopping distance based on a braking rate and a coefficient of using an adhesion force by an automated control system for regulating a braking force on the example of a multi-axle vehicle.

Braking the Gas in the beta Pictoris Disk

open access: yes, 2006
(Abridged) The main sequence star beta Pictoris hosts the best studied circumstellar disk to date. Nonetheless, a long-standing puzzle has been around since the detection of metallic gas in the disk: radiation pressure from the star should blow the gas ...

Toroidal modeling of penetration of the resonant magnetic perturbation field [PDF]

open access: yes, 2013
A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes ...

Exposing the Gas Braking Mechanism of the beta Pictoris Disk

open access: yes, 2011
Ever since the discovery of the edge-on circumstellar disk around beta Pictoris, a standing question has been why the gas observed against the star in absorption is not rapidly expelled by the strong radiation pressure from the star.
