Abstract The current method of estimating the fatigue life of railway structures is to calculating the equivalent stress amplitude based on the measured stress data. However, the random of the measured data is not consid...

Objectives: To investigate the monotonic and fatigue strength of 3D-printed 5 mol% yttria partially stabilized zirconia (5Y-PSZ) and the influences of printing layer orientation and finishing protocol. Methods: Bar-shape...

Abstract In modern fossil and nuclear power plants, the components are subjected to creep, fatigue, and creep-fatigue (CF) due to frequent start-up and shut-down operations at high temperatures. The CF interaction on the...

Abstract Cam-lobe radial-piston hydraulic motors are widely used as rotation driving units for various marine machinery owing to their ultrahigh output torque (more than 100 kN m). A multi-row cam roller bearing (MCRB) i...

People living with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) may face unique barriers to physical activity. Active video games may overcome these barriers and increase physical activity. The primary aim...

In this work, a review and mathematical analysis of phenomenological models of residual strength and residual stiffness of polymer composite materials under fatigue loading have been carried out. The methodology of the a...

OBJECTIVE: Restless legs syndrome (RLS) is a common condition in hemodialysis patients and can lead to both insomnia and fatigue. This study examines the relationship between RLS, sleep quality and fatigue in hemodialysi...

This study aims to continuously optimize the exhaust manifold to ensure long-term stability of reliable performance, and focused on exhaust manifold examining low and high cycle fatigue at high temperatures. The thermal ...

Abstract This study investigates the influence of graphene nanoparticle (GNP) reinforcement on the fatigue behavior of textile structural composites with unidirectional (UD), two-dimensional (2D) satin, and three-dimensi...

Background: The combined effects of sleep deprivation and fatigue may increase the risk of injury. Analyzing ground reaction force (GRF) components during activities such as cutting maneuvers provides valuable insights i...

Fatigue, as well as echocardiographic indices of cardiac structure and function, are both associated with adverse outcomes in heart failure (HF). However, the relationship of fatigue and echocardiographic assessments hav...

Abstract Background Fatigue is the main complaint of 5–10% of patients in primary care and is often associated with significant suffering and functional disability. Cognitive behavioral therapy (CBT) has demonstrated e...

According to Dawson and McCulloch (2005), indicating factors for pilot fatigue may be difficult to ascertain. However, fatigue is a probable cause in 15%-20% of all aircraft accidents (Akerstedt, 2000). It may be assumed...

Objective This research investigates and compares working-conditions, duty rosters, stress, sleep problems, fatigue levels, mental health, and well-being of pilots working for network (NWCs), and low-cost carriers (LCCs...

To evaluate the effect of moderate-to-high-intensity aerobic exercise performed the day before chemotherapy session on cancer-related fatigue (CRF) and to compare active vs. sedentary behaviors over the subsequent 5 day...

Gradient-based optimization offers significant efficiency advantages for wind turbine blade design, but its application has often been limited by the cost and accuracy of finite-difference derivative calculations, especi...

RationaleCommon variable immunodeficiency (CVID) is a chronic, multisystem immune disorder associated with substantial symptom burden beyond infections, particularly among individuals with noninfectious inflammatory comp...

While previous research focused on pilots’ fatigue, rosters, potential performance-impairment and aviation-safety, this research investigates, how pilots’ work-related and psychosocial stress and rosters can affect t...

Fatigue remains a significant hazard in commercial aviation and has been a major concern among all stakeholders for decades. This review of the literature explores the current prescriptive structure of the regulatory env...

Objective This study Investigates more dimensions than previous studies simultaneously: pilots’ duty rosters, stress, sleep difficulties, fatigue levels, wellbeing, symptoms of depression, anxiety, and common mental d...

Abstract This study investigated the effect of severe‐intensity exercise on neuromuscular fatigue (NMF) and torque complexity in two muscle groups of different sizes. The NMF of 11 healthy males was assessed through ma...

The risk of fatigue on pilot performance and safety is well recognized in aviation. In response to increased safety concerns, the Federal Aviation Administration addressed fatigue risk for passenger airline pilots in Tit...
