PURPOSE In magnetic resonance imaging of the brain, BLADE is used to compensate for head motion. The technique focuses mainly on acquisition of T(2)-weighted or contrast-enhanced T(1)-weighted images in adults; its utility for nonenhanced T(1)-weighted imaging in children is not well established. We compared the quality of T(1)-weighted fluid-attenuated inversion recovery brain imaging with BLA...

Currently the majority of dozing operations are conducted using tracked vehicles with a fixed blade cutting angle. There is interest from industry in exploring alternatives to tracked vehicles for small scale dozing operations because of the limitations of the platform. One alternative is a six-wheeled vehicle with independent drives and an active suspension. This alternative has higher mobilit...

A Blade Tip Timing (BTT) system enables the measurement of turbomachinery blade vibrations by means of contactless sensors mounted in the casing. In addition, the so-called Blade Tip Clearance (BTC) measurement system ensures the monitoring of the existing running gaps between the blade tip and the casing. This paper focuses on the results achieved so far using a novel magnetoresistive sensor f...

On the cover: Representation of the flow around a helicopter blade with a Gurney flap. Summary Today's helicopters are the result of collaborative work in mechanical engineering and aeronautics. The European project " Clean Sky " aims at improving the efficiency and the global transport quality of aircraft. In the field of rotorcraft, the research in this project is currently focussing on activ...

The ability to monitor the structural health of the rotating components, especially in the hot sections of turbine engines, is of major interest to the aero community in improving engine safety and reliability. The use of instrumentation for these applications remains very challenging. It requires sensors and techniques that are highly accurate, are able to operate in a high temperature environ...

Dynamic hip screw (DHS) is a well-established conventional implant for treating intertrochanteric fracture. However, revision surgery sometimes still occurs due to the cutting out of implants. A helical blade instead of threaded screw (DHS blade) was designed to improve the fixation power of the osteoporotic intertrochanteric fracture. In this study, the biomechanical properties of DHS blade co...

In this study, aeroelastic response and performance analyses have been conducted for a 5MW-Class composite wind turbine blade model. Advanced coupled numerical method based on computational fluid dynamics (CFD) and computational flexible multi-body dynamics (CFMBD) has been developed in order to investigate aeroelastic responses and performance characteristics of the rotating composite blade. R...

D-blade is a relatively new device in the field of videolaryngoscopy, designed for airway management by enabling indirectoscopic glottic view. In our study, we investigated efficiency of D-blade in comparison with direct Macintosh laryngoscope (gold standard). Fifty-two adult patients with normal airway scheduled for elective surgery in general anesthesia were randomly assigned in D-blade video...

background: there are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. in the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. methods: forty patients with valgus knee malalignment were randomly assigned to two equal numb...

in this paper, an optimization method for both weight and displacement of composite blades is presented. in   order to hold issues such as aerodynamics and acoustic unchanged, airfoil shape during optimization process remained constant. to achieve the ultimate goal, only blade lamination was changed. in order to achieve minimum weight for each part of the structure, the lowest layers are foreca...
