AbstractThis paper introduces approaches to deal with distortion created by a singlet lens camera. Due to the inherent optical defect of singlet lenses, considerable lens aberrations will appear in the resulting image, especially at high field angles.

Distortion Correction in Anomalous Absorption Coefficients
physica status solidi (b), 1967AbstractBased on a recent theory of X‐ray diffraction by a distorted crystal completed by the present author, the temperature and distortion corrections in anomalous absorption coefficients have been studied in the case of a single symmetric Bragg reflection in transmission (symmetrical Laue case).

The parameterization of a 3D mesh into a planar domain requires a distortion metric and a minimizing process. Most previous work has sought to minimize the average area distortion, the average angle distortion, or a combination of these. Typical distortion metrics can reflect the overall performance of parameterizations but discount high local ...

Measuring and Visualizing Patterns of Ethnic Concentration: The Role of Distortion Coefficients
Geographical Analysis, 2021The paper provides numerical measures and visualizations of urban segregation based on a new index, the Distortion coefficient. Distortion coefficients are derived from trajectories of contact with the city’s population as an individual will encounter an increasing number of persons in a growing distance from their original location.

On the harmonic distortion coefficients of active-loaded amplifiers
International Journal of Electronics, 1992Starting from the modified Ebers-Moll model which represents the Early effect more accurately than conventional models with the Early voltage, new expressions to calculate the harmonic distortion coefficients of active-loaded BJT amplifiers are derived and applied to the determination of the optimum operating point, where the total harmonic distortion ...

This paper focused on nonlinear distortion modeling and characterization of AlGaN/GaN HEMT on SiC substrate using a two-tone intermodulation measurement. The variation of Taylor series coefficients with temperature: linear terms (G$_m$ and G$_d$$_s$), nonlinear terms (G$_m$$_2$ , G$_m$$_3$ , G$_d$$_s$$_2$, and G$_d$$_s$$_3$), and the cross terms (G$_m$$

The rotational Hamiltonian of an asymmetric-top molecule, containing terms up to sixth degree in the components of the total angular momentum, is transformed by a unitary transformation to a reduced Hamiltonian, so as to avoid the indeterminacies inherent in fitting the complete Hamiltonian to observed energy levels.

Distortion analysis of the coding scheme based on coefficient rate
Proceedings. 1998 IEEE International Symposium on Information Theory (Cat. No.98CH36252), 2002Previously the authors (1997) proposed a new source coding scheme based on the investigation of Campbell's coefficient rate. This scheme can adaptively encode the transform coefficients by controlling the number of coefficients to be coded for each sample function.

Expected Distortion of Dct-Coefficients in Video Streaming over Unreliable Channel
2006The Recursive Optimal per-Pixel Estimate (ROPE) algorithm allows the encoder to estimate the pixel-by-pixel expected distortion of the decoded video sequence due to channel loss. The algorithm requires in input an estimate of the packet loss rate and the knowledge of the error concealment technique used at the decoder with no need to perform any ...
