Vascular KCNQ channels in humans: the sub‐threshold brake that regulates vascular tone? [PDF]

British Journal of Pharmacology, 2010
Contraction of arterial smooth muscle cells results in vasoconstriction, which in turn reduces blood flow and increases blood pressure. There has been a great deal of interest in understanding the ionic mechanisms that regulate smooth muscle contraction, in part because ion channels represent potential pharmacological targets for therapies directed ...

A Logic Threshold Control Strategy to Improve the Regenerative Braking Energy Recovery of Electric Vehicles

Sustainability, 2023
With increasing global attention to climate change and environmental sustainability, the sustainable development of the automotive industry has become an important issue. This study focuses on the regenerative braking issues in pure electric vehicles. Specifically, it intends to elucidate the influence of the braking force distribution of the front and

Analysis Of Thresholds In Rule-Based Antilock Braking Control Algorithms

IFAC-PapersOnLine, 2020
Abstract An Antilock Braking System (ABS) is an Active Vehicle Safety System (AVSS) employed to prevent wheel lock in road vehicles. Wheel lock is undesirable as it may lead to loss of vehicle steerability and directional stability. These become critical in Heavy Commercial Road Vehicles (HCRVs) as unintentional yaw motion resulting from directional ...

Using perceptual cues for brake response to a lead vehicle: Comparing threshold and accumulator models of visual looming [PDF]

Accident Analysis & Prevention, 2018
Previous studies have shown the effect of a lead vehicle's speed, deceleration rate and headway distance on drivers' brake response times. However, how drivers perceive this information and use it to determine when to apply braking is still not quite clear.

The rotation-magnetic field relation [PDF]

, 2008
Today, the generation of magnetic fields in solar-type stars and its relation to activity and rotation can coherently be explained, although it is certainly not understood in its entirety. Rotation facilitates the generation of magnetic flux that couples

An ABS control logic based on wheel force measurement [PDF]

, 2012
The paper presents an anti-lock braking system (ABS) control logic based on the measurement of the longitudinal forces at the hub bearings. The availability of force information allows to design a logic that does not rely on the estimation of the tyre ...

Safety and Security Analysis of AEB for L4 Autonomous Vehicle Using STPA [PDF]

, 2019
Autonomous vehicles (AVs) are coming to our streets. Due to the presence of highly complex software systems in AVs, there is a need for a new hazard analysis technique to meet stringent safety standards. System Theoretic Process Analysis (STPA), based on

A Vehicular Traffic Flow Model Based on a Stochastic Acceleration Process [PDF]

, 2004
A new vehicular traffic flow model based on a stochastic jump process in vehicle acceleration and braking is introduced. It is based on a master equation for the single car probability density in space, velocity and acceleration with an additional ...

Characterization of surface morphology and its correlation with friction performance of brake pads [PDF]

, 2015
The present work presents the morphology evolution of a brake material surface submitted to braking tests through a laboratory-scale tribometer. Optical microscope images of the material’s surface were obtained for every 10 braking operations.
