Design and Experimental Verification of a 1/20 Scale Model of Quayside Container Crane Using Distortion Theory

open access: yesShock and Vibration, 2019
The scale model is an effective method to research the performance of quayside container crane (QCC) under the seismic condition, but the model distortion usually exists in the similar design process which leads to the incomplete similarity between the ...

Distortion coefficients for cryptocontractions

open access: yesLinear Algebra and its Applications, 1977
AbstractFor complex Hilbert space H of d dimensions and for any number K ⩾ 1, we may define m(K, d) as the least number with the following property: if ‖p(T)‖ ⩽ K for all polynomials p mapping the complex unit disk into itself, then the operator T may be made a contraction by changing to a new norm |·|, derived from an inner product, such that ‖h‖ ⩽ |h|

Facilitating PTZ Camera Auto-Calibration to Be Noise Resilient With Two Images

open access: yesIEEE Access, 2019
This paper presents a simple but effective technique to calibrate a PTZ (Pan/Tilt/Zoom) camera by using only two images for five intrinsic parameters: focal length, aspect ratio, the principle point coordinates and the distortion coefficient.

Generalization of certain subclasses of analytic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1987
We introduce the subclass Tj(n,m,α) of analytic functions with negative coefficients by the operator Dn. Coefficient inequalities and distortion theorems of functions in Tj(n,m,α) are determind.

Extremal properties of Sobolev’s Beltrami coefficients and distortion of curvelinear functionals

open access: yesJournal of Mathematical Sciences, 2023
An important problem in applications of quasiconformal analysis and in its numerical aspect is to establish algorithms for explicit or approximate determination of the basic quasiinvariant curvelinear and analytic functionals intrinsically connected with conformal and quasiconformal maps, such as their Teichmüller and Grunsky norms, Fredholm ...

Estimation of correlation coefficient with monotone transformation and multiplicative distortions

open access: yesCommunications in Statistics - Theory and Methods, 2023
This article studies the estimation of the correlation coefficient between unobserved variables of interest. These unobservable variables, mixed with some known monotone link functions, are distorted in multiplicative fashion by an observed confounding variable.
