The critical effect of rail vertical phase response in railway curve squeal generation
, 2020 Squeal of rail-bound vehicles emitted in tight curves is characterized by high sound pressure levels at pure medium and high frequencies. Many models have been proposed in the literature to explain the occurrence of this noise with different instability ...

Some unexpected thermal effects on squeal events observed on the experimental bench FIVE@ECL
, 2021 The proposed study investigates the potential links between thermal effects and structural modifications of a brake system which can lead to minor modifications of the nonlinear squeal signature at temperatures lower to 100 °C.

Riding on a Pegasus: Is ‘Sustainability’ Still a Myth in Bangladesh's RMG Sector?
Business Strategy and the Environment, EarlyView.ABSTRACT Although a growing number of studies explore sustainability, the role of stakeholders and institutions in shaping environmental sustainability initiatives remains overlooked particularly from the upstream fashion supply chain contexts. Drawing upon the framework proposed by Lee, our study aims to fill this gap by examining the interplay ...

Effect of Temperature Variations on Brake Squeal Characteristics in Disc Brake Systems
Engineering ProceedingsBrake squeal is an undesirable high-frequency noise caused by vibrations induced by friction in disc brake systems. The noise is strongly affected by temperature, as this influences the material properties of the friction pair and the dynamic behaviour ...

The Age of Questions: Truth Regimes and Subjectivity in the Era of Large Language Models
Behavioral Sciences &the Law, EarlyView.ABSTRACT This essay explores how digital technologies shape subjectivity's infra‐political constitution, focusing on large language models (LLMs) like ChatGPT or Gemini within what philosophers, inspired by Michel Foucault, term the “digital truth regime.” After defining this regime, the essay identifies five key traits of LLMs: presentism in truth ...

Brake Squeal: Modeling and Energy Harvesting [PDF]
, 2017 This dissertation aims at developing the fundamentals necessary for mitigating the adverse effect of vibration and noise induced by brake squeal. Such a process is achieved by embedding an array of piezoceramics into the brake system which are provided ...

From Probation to Partnership: Building Equitable Systems of Support in Community Colleges
New Directions for Community Colleges, EarlyView.ABSTRACT Community colleges serve as critical gateways to higher education for diverse student populations, yet traditional academic probation systems often exacerbate inequities by penalizing students facing systemic and personal challenges. This practitioner–scholar case study examines Clark State College's Academic Engagement Program (AEP), an ...

Finite element analysis on squeal-noise in railway applications [PDF]
FME Transactions, 2018 In this paper, we present the results of an experimental investigation on squeal noise emitted by a disc brake for railway applications. The measurement, that show in an evident manner the onset of instability forms during the braking phase were made on ...
