BACKGROUND Postcancer fatigue is a frequently occurring problem, impairing quality of life. Until now, little is known about (neuro) physiological factors determining postcancer fatigue. For non-cancer patients with chronic fatigue syndrome, certain characteristics of brain morphology and metabolism have been identified in previous studies. We investigated whether these volumetric and metabolic...

Driver fatigue is one of the major causes traffic accidents, and this need has increased amount driver detection systems in vehicles order to reduce human material losses. This work puts forward an approach based on capturing near-infrared videos from a camera mounted inside vehicle. Then, captured images using image-processing techniques eyes are detected. Next, features extracted eye several ...

For critical component application, such as aerospace turbine rotors, it is imperative to be able make accurate in-service material behaviour and life predictions for both design monitoring of life. The development predictive capability dependent on the quality experimental data from which parameters are derived. This paper shows effect that scatter may present within data, manifesting itself c...

The role of cold work reduction and its effect on fatigue properties are examined by means of rotary beam fatigue testing. In this study, processing parameters from the initial ingot to the final size before finish drawing were held constant. Fatigue specimens were prepared with between 20 and 55% cold work in five percent increments. These samples were subsequently heat treated, cut into test ...

Fatigue is reported as the most common symptom by patients with multiple sclerosis (MS). The physiological and functional parameters related to fatigue in MS patients are currently not well established. A new wearable wireless body measurement system, named Fatigue Monitoring System (FAMOS), was developed to study fatigue in MS. It can continuously measure electrocardiogram, body-skin temperatu...

The measurement of acoustic nonlinear response is known as a promising technique to characterize material micro-damages. In this paper, nonlinear ultrasonic approach is used to characterize the evolution of fatigue induced micro-cracks in polymer bonded explosives. The variations of acoustic nonlinearity with respect to fatigue cycles in the specimens are obtained in this investigation. The pre...
