Detection of main tidal frequencies using least squares harmonic estimation method
Journal of Geodetic Science, 2012 In this paper the efficiency of the method of Least Squares Harmonic Estimation (LS-HE) for detecting the main tidal frequencies is investigated. Using this method, the tidal spectrum of the sea level data is evaluated at two tidal stations: Bandar Abbas

Ultrasonic characterisation of malignant melanoma of choroid
Indian Journal of Ophthalmology, 1998 An in-vitro study of wave spectral analysis in 8 enucleated eyes was conducted in order to differentiate histological subtypes of malignant melanoma. To obtain the backscattering coefficient for the tissues, we used a broadband focussed transducer with a

Spectral Analysis for Nonlinear Spectral Analysis\ud Part 1: Parametric Nonlinear Spectral Analysis
, 1988 A new theory of spectral analysis for nonlinear systems is introduced. The method consists of estimating the parameters in a NARMAX model description of the system and then computing the generalised frequency response directly from the estimated model. The paper is divided into into three parts. Part 1 introduces a methodology for estimating the models

A Review of Multitaper Spectral Analysis
IEEE Transactions on Biomedical Engineering, 2014Nonparametric spectral estimation is a widely used technique in many applications ranging from radar and seismic data analysis to electroencephalography (EEG) and speech processing. Among the techniques that are used to estimate the spectral representation of a system based on finite observations, multitaper spectral estimation has many important ...

2021 13th International Conference on Electronics, Computers and Artificial Intelligence (ECAI), 2021
The properties, transformation processes and functions of the soil can vary in time and space and therefore requires the development of new methods for measuring and monitoring it. The conventional laboratory methods used to analyse the properties of the soil have a number of shortcomings, which often make them inapplicable for monitoring the ...
