Effects of a Non-Circular Chainring on Sprint Performance During a Cycle Ergometer Test
Elliptical chainring clipless pedal maximal power output equipment design force-velocity test
2016/7/7
Non-circular chainrings have been reported to alter the crank angular velocity profile over a pedal revolution so that more time is spent in the effective power phase. The purpose of this study was to...
Orthogonalization of Circular Sequences and its Application to the Gabor Decomposition
Orthogonalization Circular Sequences Application Gabor Decomposition
2010/1/7
Certain vector sequences in Hermitian or in Hilbert spaces, can be orthogonalized by a Fourier transf‘orm. In the Anite-dimensional case, the discrete Fourier transform OFT)
accomplishes the orthogon...
Analysis of Cone-Beam Artifacts in off-Centered Circular CT for Four Reconstruction Methods
Cone-Beam Artifacts CT
2009/9/8
Cone-beam (CB) acquisition is increasingly used for truly three-dimensional X-ray computerized tomography (CT). However, tomographic reconstruction from data collected along a circular trajectory with...
An Efficient Estimation Method for Reducing the Axial Intensity Drop in Circular Cone-Beam CT
Estimation Method Circular Cone-Beam CT
2009/9/4
Reconstruction algorithms for circular cone-beam (CB) scans have been extensively studied in the literature. Since insufficient data are measured, an exact reconstruction is impossible for such a geom...
Ilizarov methodology for infected non union of the Tibia: Classic circular transfixion wire assembly vs. hybrid assembly
Hybrid assembly Ilizarov infected nonunion
2008/11/27
Introduction: Conventional wire fixation of Ilizarov rings often fails to provide 90-90 configuration because of vital structures, which is essential for optimum stability. Hybrid assembly with half p...
