This paper aims to assess the application of Support Vector Machine (SVM) regression in order to analysis flexible pavements. To this end, 10000 Four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

purpose: to investigate the effects of sodium bicarbonate (nahco3) on exhaustive activity and physiological parameters of fatigue in conscripts. materials and methods: thirty conscripts did wingate test in two groups: sodium bicarbonate group (treatment) and placebo (control) group. in both groups, sodium bicarbonate (0.3 g/kg of body mass) or placebo was ingested 60 minutes before the training...

Experimental investigation was conducted on corroded composite push-out specimens to study the behavior of shear studs subjected to fatigue loading. A total of eight standard EC4 push-out specimens were tested. The expected corrosion rate of test specimens ranged from 0 to 50%. The main purpose of these tests was to determine the fatigue life and the reduction effect caused by the corrosion on ...

Faults occurring in machine elements are often related to non-linear effects which may lead to non-linearities in the machine vibration signature. This paper concerns the application of signal processing techniques based on Higher Order Spectra (HOS) to the condition monitoring of mechanical systems. These techniques give more information than the power spectra and are particularly useful in si...

OBJECTIVES To compare cognitive and emotional outcomes between patients with aneurysmal and perimesencephalic subarachnoid haemorrhage and norm scores. DESIGN First measurement in prospective cohort study. PATIENTS Sixty-seven patients with subarachnoid haemorrhage, were divided into perimesencephalic (n = 8) and aneurysmal (n = 59) subarachnoid haemorrhage groups. METHODS Patients comple...

Fatigue tests are a very time consuming process in engineering, in which also a lot of energy is required. Speeding up fatigue tests and making them less energy consuming, would lead to major profits. The aim of this study is to obtain these profits by the development of a new bending fatigue test. In addition, the objective is to apply this new method to the bending fatigue test of rings from ...

BACKGROUND AND PURPOSE Pain is currently evaluated with "subjective" methods (eg, patient self-report). This study aimed to test whether fatigue indexes are able to accurately discriminate between subjects with and subjects without low back pain. SUBJECTS Sixty subjects separated into 2 groups--a group with low back pain (n=30) and a group without low back pain (n=30)--participated in this st...

Fatigue refers to the decrement of response seen with repeated stimulation and is a prominent attribute of nociceptors. Whether fatigue in nociceptors involves transduction, spike initiation, or conduction mechanisms is unknown. We investigated systematically how electrical, mechanical, and heat conditioning stimuli (eCS, mCS, hCS) affected the subsequent response to a test-heat stimulus applie...
