Estimating the effect of cold forming and post processing on fatigue of high strength steels under component-related loading conditions

Stamping and shot peening of chassis components such as wheels and cross beams introduce residual stresses that affect the fatigue life. The tensile residual stresses from stamping are often found in the most critical areas for fatigue. These areas are commonly subject to bending stress states while smooth material fatigue data for steel sheets more commonly is obtained by uniaxial testing. Both the sensitivity to residual stresses and change in load condition are material dependent posing a ...

Realistic Sheared Flow Profile Effects on Acoustic Impedance Eduction in Small Three-Dimensional Ducts

We investigate the influence of realistic sheared grazing flow on acoustic propagation in three-dimensional rectangular ducts. We show that the conclusions reached in the literature about the effects of sheared grazing flow on acoustic propagation in lined ducts are dependent on the flow profiles used in those studies and that significantly different conclusions are reached once a realistic flow profile is used. We particularly focus on small ducts typical of most experimental impedance educt...

Navigating the AI regulatory landscape: Balancing innovation, ethics, and global governance

The rapid development of artificial intelligence (AI) has generated transformative opportunities alongside significant ethical, societal, and regulatory challenges. In this paper, we analyse this issue by considering the different approaches and regulatory frameworks of three main actors: the European Union (EU), the United States (US), and China. The analysis shows how they are adopting different strategies: the EU proposes a stringent, risk-based framework to ensure accountability and trans...

Design and development of a feedback system for automatic treadmill speed adaptation

Treadmills with automatic speed adjustment offer a unique advantage: they can mimic outdoor conditions for specific training or testing protocols. This versatility makes them highly applicable in both sports and rehabilitation settings. This study presents a novel framework based on a feedback control loop system, conceived to control a treadmill belt speed using a non-invasive and low-cost sensor (Microsoft Kinect) to detect the users' position and avoid object obstruction issues. The speed ...

CardioSmartAssist: A customisable AI framework for echocardiography-based cardiac assessment

Background and Objective. Cardiovascular diseases (CVDs) remain the leading cause of mortality worldwide, accounting for approximately 20.5 million deaths annually, nearly one-third of all global deaths. Despite its central role in cardiology, echocardiographic assessment remains subject to significant inter- and intra-observer variability, particularly based on manual frame selection and segmentation. This limitation has driven increasing interest in Deep Learning (DL) solutions capable of e...
