This paper deals with the control and stability enhancement of a wind power generation system feeding active load with constant power characteristic. The under study system is a combined wind-battery generation system with permanent magnet synchronous generator (PMSG) supplying active load by using interfaced power electronics converters. The employed active load is indeed an active rectifier b...

Background & Aims:  Scoliosis is linked with asymmetrical compression loads induced by trunk muscles and external loads. The objective of this study was to measure the electrical activity of bilateral erector spinae muscles during the rest in the standing, sitting and lying positions. Materials & Methods: Ten patients with double curvature (right thoracic and left lumbar) scoliosis...

With the demand for turbomachinery to operate at higher speeds, loads, and power, fluid film bearings that support turbomachinery must be capable of operating in these more demanding applications. Thrust bearings operating at high speeds and loads can experience high surface temperatures and thin fluid film thickness. Typically, babbitt (white metal) is the bearing lining material for most turb...

conclusions this study indicates that low-load rt results in greater accumulations in vl compared to high-load rt over the course of 8 weeks of training. results after adjusting for the pre-test scores, there was a significant difference between the two intervention groups on post-intervention total vl with a very large effect size (f (1, 15) = 16.598, p = .001, ηp2 = .525). there was a signifi...

Occurrence of top down and bottom up fatigue cracking in asphaltic pavements is common. Conventional pavement analysis methods ignore the existence of cracks in asphaltic layers. However, it seems that the responses of cracked pavement would not be the same as a pavement without crack. This paper describes effects of crack type, position and length, and vehicles tire inflation pressure and axle...

This work is carried out to investigate combustion characteristics of a dual fuel (diesel-gas) engine at part loads, using a quasi-dimensional multi zone combustion model (MZCM) for the combustion of diesel fuel and a single zone model with detailed chemical kinetics for the combustion of natural gas fuel. Chemical kinetic mechanisms consist of 184 reactions with 50 species. This combustion mod...

Background: Hepatitis activity index (HAI) and fibrosing stage are two important findings during the evaluation of liver samples in patients with chronic hepatitis B. The aim of this study was to determine the HAI and fibrosing stage in patients with anti-HBe positive chronic hepatitis B. Methods: Liver biopsy slides of 72 patients were evaluated at the Department of Pathology in two teaching ...

UNLABELLED The achievement of a well-balanced total knee arthroplasty is necessary for long-term success. We hypothesize that the dislocation of the patella during surgery affects the distribution of loads in the medial and lateral compartments. Intraoperative load sensors were used to record medial and lateral compartment loads in 56 well-balanced TKAs. Loads were recorded in full extension, r...
