On parameter transformations and interval estimation
Biometrika, 1984Parameterizations which reduce the asymptotic bias and skewness of various pivotal quantities arising in large-sample theory are discussed for models depending on an unknown scalar parameter. Transformation formulae by which such parameterizations can be obtained are derived, and these formulae extend those for one-dimensional curved exponential ...

One-parameter symmetry transformations
Il Nuovo Cimento A Series 10, 1967A theorem is proved for one-parameter groups of automorphisms commuting with the time trnnslations. Si dimostra un teorema per i gruppi ad un parametro degli automorfismi che commutano con le translazioni del tempo.

Parameter Recovery Using Radon Transform
Proceedings of the 16th International Conference on Advances in Mobile Computing and Multimedia, 2018In computer vision, alignment of images plays an important role in different day to day life applications by bringing similar points of images into correspondence. Conventionally, images are aligned by using the extracted features of images. However, the extraction of features is difficult, time consuming and not suitable for low quality images ...

Fast Transformation for DAC Parameters Identification
2005 IEEE Instrumentationand Measurement Technology Conference Proceedings, 2006Modeling of digital-to-analog converters (DACs) and identification of their critical parameters are dealt with. The attention is focused on a well-known static model accounting for linearity and intermodulation errors, which are of major concern for DAC functional characterization as well as troubleshooting.

A One-Parameter Family of Sequence Transformations
SIAM Journal on Mathematical Analysis, 1979A one-parameter family of sequence or series transformations is presented which includes the Pade and the iterated Aitken’s (Shanks) tables as special cases. The transformation table elements are rational functions with polynomial coefficients in the parameter that, when expanded for small argument, are asymptotically equivalent to the highest order ...

Mathematically, parameters are the unknown quantities θ in the likelihood function, L(θ), whose values \( \hat \theta \) at the optimum are regarded as giving the best fit of the model to the data. There is an unlimited number of ways of writing the same model in terms of different sets of parameters. But the reasons for a particular parametrization of

Affine Parameter Estimation from the Trace Transform
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2003In this paper, we assume that we are given the images of two segmented objects, one of which may be an affinely distorted version of the other, and wish to recover the values of the parameters of the affine transformation between the two images. The images may also differ by the overall level of illumination.

On the discretization of parameter domain in Hough transformation
Proceedings of 13th International Conference on Pattern Recognition, 1996Although the basic principle of Hough transformation can be described accurately in continuous spaces, its application is often conducted in digitized ones. The discretization of both a spatial image and the related transformation parameters will result in positioning errors in the parameter domain that affect the accumulation through which the Hough ...

Transformation and Load Parameters of the Disk Piezoelectric Transformer
IEEE Transactions on Power Electronics, 2016The main aim of this paper is the theoretical analysis and experimental verification of the transformation parameters for the nonhomogeneously poled disk transformer with an excellent transformation ratio and efficiency. The input part is poled in thickness direction and output part in radial direction.
