A Similarity Parameter for Scaling Dynamic Inlet Distortion
Journal of Engineering for Industry, 1974 A similarity parameter suitable for use in both analog and digital analyses of time-dependent inlet pressure distortion data has been developed. This parameter, when used in conjunction with the recently developed Method D distortion methodology, facilitates prediction of full scale instantaneous pressure distortion levels from scale model inlet ...

Analytically Solving Radial Distortion Parameters
2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2005Most camera calibration algorithms consider parameters that define the lens distortion mapping. The usual way to determine these parameters is to minimize a nonlinear optimization problem in the final step of a calibration algorithm. This neglects the fact that given the projection matrix and the calibration data the parameters of a radial distortion ...

Ligand field distortion parameters
Theoretica Chimica Acta, 1975The factorization of ligand field parameters into angular and radial contributions is examined. The angular term breaks up into a product of geometric and chemical environment tensors each of which contributes to the magnitude of the distortion parameter. The purely geometric function may be expressed as axial projections which need not represent metal-

Influences of welding parameters on distortion
International Journal of Microstructure and Materials Properties, 2010Laser beam welding (LBW) is an established serial process in manufacturing of parts for aircraft industries, which is characterised by the advantages of weight reduction and shortened process time compared to conventional riveting techniques. However distortions can occur after LBW. Depending on the intensity the distortions impair, e.g., assembly work

Resonance Properties Of Bragg Structures With Parameter Distortion
MMET Conference Proceedings. 1998 International Conference on Mathematical Methods in Electromagnetic Theory. MMET 98 (Cat. No.98EX114), 2002The reflection and polarization transformation of electromagnetic waves propagating in a medium with small longitudinal gyrotropy and weak longitudinal inhomogeneity are theoretically considered. Using a complex form of the asymptotic method of Krylov, Bogoliubov and Mitropolsky, expressions for coupling coefficients of propagating waves are derived ...

Estimating Distortion Parameters in Simulated Prosthetic Vision
2013 IEEE International Conference on Healthcare Informatics, 2013Designing a retinal prosthesis that provides functional vision to users is a challenging problem due to the large design parameter space and the spatial distortions experienced by users. We describe an environment to simulate prosthetic vision in normal-sighted individuals which can be used to obtain information about the designing and tuning of a ...

Range parameter distortion in heavy ion implantation
Physics Letters A, 1975Abstract 20 to 145 keV xenon range profiles in silicon have been determined as a function of the implantation fluence. Shortening of the most probable projected range and increase in range straggling were observed at fluences usually implanted for range measurements by means of the back-scattering technique.

Areal parameters for the characterisation of gear distortions
Materialwissenschaft und Werkstofftechnik, 2012AbstractGear distortion is influenced by several effects which might originate in various steps of the entire production chain. To understand the distortion mechanisms including interactions between different influencing parameters, a system approach for the whole production process is required. As distortion is not constrained to the toothing but also

Parameter isolating transforms and admissible distortions
ICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005An often encountered pattern recognition problem is that of identifying a given image as related to one of a set of prototypes even though they may differ by virtue of the action of a non-linear mapping of image points. Certain parameterized distortions are such that a transform may be found that has the property of isolating the distortion effect as a
