Detection of Emergency Braking Intention Based on Pedal-Switching Process

IEEE Access
The driver’s reaction time and the brake actuator response time during emergency braking play a crucial role in braking distance. Detecting the driver’s braking intention and reducing actuator reaction time can enhance the safety advantages

M. E. Grant Duff, Philosophic Liberalism and the Global Liberal Cause

History, EarlyView.
Abstract Historians disagree about how best to conceptualize nineteenth‐century British Liberalism in relation to its international contexts. This article argues that we can better understand the patterns involved by interrogating individuals who bridged the worlds of partisan politics and elaborated thought.

Can prisons move people into better jobs? A look at correctional vocational training programs and sectoral employment outcomes

Criminology, EarlyView.
Abstract Three‐quarters of US prisons offer vocational training programs, which aim to place trainees in middle‐skills jobs in specific occupational sectors post‐release. These middle‐skills jobs may more effectively reduce recidivism than the jobs that normally characterize the labor market experience of the formerly incarcerated, yet whether ...

Relative Perturbation Theory for Quadratic Eigenvalue Problems [PDF]

, 2016
In this paper, we derive new relative perturbation bounds for eigenvectors and eigenvalues for regular quadratic eigenvalue problems of the form $\lambda^2 M x + \lambda C x + K x = 0$, where $M$ and $K$ are nonsingular Hermitian matrices and $C$ is a ...
