Dataset of vibrational and acoustic measurements for squeal analysis from the laboratory brake setup Friction-Induced Vibration and noisE at Ecole Centrale de Lyon (FIVE@ECL)

Data in Brief, 2018
This data article comprises raw records to investigate the dynamic behavior of a brake system during controlled braking tests and its squeal characterization through the generation of friction-induced vibration.

Curve squeal in sharp curves: effect of multiple wheel/rail contact points

Applied Acoustics
Curve squeal is one of the most annoying noise problems related to the operation of trains, trams, and metros in urban environments. It typically occurs in sharp curves, which are very common in urban areas, and is disturbing for both passengers and ...

Design oriented simulation of contact-friction instabilities in application to realistic brake assemblies [PDF]

, 2010
This paper presents advances in non-linear simulations for systems with contact-friction, with an application to brake squeal. A method is proposed to orient component structural modifications from brake assembly simulations in the frequency and time ...

Barbed Sutures Are Associated With a Lower Incidence of Incisional Hernia Compared With Continuous Non‐Barbed Monofilament Sutures After Minimally Invasive Gastroenterological Surgery

Annals of Gastroenterological Surgery, EarlyView.
Incisional hernia remains a common complication after minimally invasive gastroenterological surgery despite small extraction incisions. In this propensity score‐weighted analysis, barbed sutures significantly reduced the incidence of incisional hernia compared with conventional slowly absorbable monofilament sutures without increasing postoperative ...

Immigration detention centers as torturing environments: Ethical reckonings, radical refusals, and implications for a psychology of resistance

American Journal of Community Psychology, EarlyView.
Abstract This paper examines psychologists' ethical dilemmas in immigration detention centers. Using critical psychology, border, and detention scholarship, it highlights psychologists' historical complicity in state violence, from the U.S. Enhanced Interrogation Program to current border regimes.

Benchmarking Signorini and exponential contact laws for an industrial train brake squeal application [PDF]

, 2012
Contact representation of structure interactions for finite element models is nowadays of great interest in the industry. Two contact modellig strategies exist in the literature, either based on a perfect contact with no interpenetration of structures at

Ritualized reflection in human dissection: Liminality, ethical negotiation, and professional identity formation among South Korean medical students

Anatomical Sciences Education, EarlyView.
Abstract Human dissection is a foundational component of medical education, yet it places students in profound ethical tension between scientific objectification and respect for human dignity. While prior studies have documented students' emotional responses, the structural transformation of their moral narratives over time, particularly within non ...

Performances of the double modal synthesis for the prediction of the transient self-sustained vibration and squeal noise

Applied Acoustics, 2021
This paper presents an efficient reduction method for predicting the nonlinear transient and steady state squeal events in mechanical systems subjected to friction-induced vibration and noise.

Electroconvulsive Therapy for Catatonia in Autistic and Non‐Autistic Patients: An Observational Study on Course, Efficacy, Aggression, and Self‐Injury Outcomes

Autism Research, EarlyView.
ABSTRACT Catatonia occurs disproportionately in autistic individuals and may respond to electroconvulsive therapy (ECT), yet prior reports suggest greater treatment burden in this population. We compared longitudinal ECT utilization, safety, and clinical outcomes between autistic and non‐autistic patients with catatonia.

Tribology performance, airborne particle emissions and brake squeal noise of copper-free friction materials

, 2020
Copper and its alloy have been widely used in the formulation of non-asbestos organic (NAO) friction materials as reinforcements and/or additives. But U.S.A has raised a legislation to reduce the copper content in friction materials due to the toxicity ...
