In this study, the low-speed performances of Busemann biplane were clarified, focusing on relative contributions upper and lower elements to total aerodynamic characteristics biplane. Also, effects staggered biplane, which changes horizontal distance between two wings in a configuration, investigated by balance measurements numerical simulations. The flow velocity was 15 m/s, Reynolds number ba...

In this study, mathematical modeling of biplane quadrotor with slung load is proposed. Performance the degrade while swinging so to compensate it nonlinear observer based backstepping controller designed that can not only handle disturbance generated by but also capable tackle partial rotor failure and wind gust. Simulation study carried out considering (only for mode), gust, (for all three mod...

A technique is developed that will calculate accurate and reliable imaging geometries and three-dimensional (3D) positions from biplane images of a calibration phantom. The calculated data provided by our technique will facilitate accurate 3D analysis in various clinical applications. Biplane images of a Lucite cube containing lead beads 1 mm in diameter were acquired. After identifying corresp...

In developing the next generation supersonic transport airplane, two major challenges must be resolved. The fuel efficiency must be significantly improved, and the sonic boom propagating to the ground must be dramatically reduced. Both of these objectives can be achieved by reducing the shockwaves formed in supersonic flight. The Busemann biplane is famous for using favorable shockwave interact...

Results Commonly used biplane[1] and triplane[1] ellipsoid models have significant mean percentage error (at least 9%) for EDV/ESV/EF (Table 1), and triplane model was more reproducible than bi-plane model. A linear-weighted model of biplane and parabola substantially diminishes percentage error for EDV, ESV and EF to 0.3±6.0%, 0.5±10.7% and 0.0±6.4% (aEDV = 0.4, bEDV=0.7; aESV = 0.9, bESV=0.2)...

To compare measurements of left ventricular size and performance obtained by apical biplane cross-sectional echocardiography (CSE) and gated equilibrium radionuclide angiography (RNA), we studied 70 patients, all of whom had single-plane and 30 of whom had biplane left ventricular cineangiography. Wideangle, phased-array CSE images were obtained from two orthogonal apical views and left ventric...

OBJECTIVE To assess the technical feasibility and local efficacy of percutaneous radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) for an intermediate-sized (3-5 cm in diameter) hepatocellular carcinoma (HCC) under the dual guidance of biplane fluoroscopy and ultrasonography (US). MATERIALS AND METHODS Patients with intermediate-sized HCCs were treate...

To evaluate the applicability of two-dimensional echocardiography to left ventricular volume determination, 30 consecutive patients undergoing biplane left ventricular cineangiography were studied with a wide-angle (84 degrees), phased-array, two-dimensional echocardiographic system. Two echographic projections were used to obtain paired, biplane, tomographic images of the left ventricle. We us...

OBJECTIVES To evaluate the ability of an alignment jig/saw guide to reproduce appropriate osteotomy positions in the tibial plateau leveling osteotomy (TPLO) in the dog. METHODS Lateral radiographs of 65 clinical TPLO procedures using an alignment jig and freehand osteotomy performed by experienced TPLO surgeons using a 24 mm radial saw blade between Dec 2005-Dec 2007 and Nov 2013-Nov 2015 we...

HERE is no question in the development of aviation more interesting to the average observer than the relative value of the biplane and the monoplane. Types of both have so multiplied and differentiated that the man on the street can no longer distinguish at sight, say, a Nieuport from any other of the monoplanes to which Bleriot accustomed him, or pick out a Farman, a Sommer, a Voisin, from oth...
