Extraction of pertinent parameters in oceanographic data

Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002
The purpose of this publication is to present a new technique for processing bathythermic profiles in order to extract pertinent oceano-acoustic points which characterise each considered area. The proposed approach, based on standard signal processing and post-processing techniques, brings the advantage to be general, no matter the considered ...

Parameter Extraction of ECG Using Labview

2018 15th International Multi-Conference on Systems, Signals & Devices (SSD), 2018
The electrocardiogram presents the electrical activity of the heart, which informs about the condition of the heart muscle. The interpretation and diagnostic of this signal lead to detect various cardiac abnormalities and diseases, for that the feature extraction and the denoising are very useful in cardiology.

On the extraction of the design parameters of power BJTs

2017 International Conference on Control, Automation and Diagnosis (ICCAD), 2017
In this paper, in order to decouple the design parameters of power bipolar junction transistors during their extraction, our work focuses on the study of the variation effect of the design parameters on the static and dynamic characteristics of the power BJT. Indeed, an attempt is made to assign a specific characteristic to each design parameter, which

Decomposition-based model parameter extraction

Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002
This paper presents a decomposition-based approach to model parameter extraction. The new parameter extraction technique combines virtues of sequential regression and full optimization approaches. Extraction of the SPICE2 BJT model parameters illustrates concepts and advantages of the proposed method.

Extraction of Dispersion Parameters

2016
As demonstrated previously, the propagation of waves in distributed and discrete periodic structures can be described by a set of dispersion parameters such as wavenumber and Bloch impedance or by effective material parameters. In this chapter, different methods to obtain these parameters from a given geometry are introduced and investigated.

OFDM Modulation Classification and Parameters Extraction

2006 1st International Conference on Cognitive Radio Oriented Wireless Networks and Communications, 2006
A novel comprehensive classification system is proposed for recognizing the orthogonal frequency division multiplexing (OFDM) signal and extracting its parameters. An empirical distribution function -based Gaussianity test technique is first applied to distinguish OFDM from single carrier modulations.

The Feature Extraction From the Parameter Space

2016
In this article a new solution of characteristic points of the image from the parameter space is presented. The implemented algorithm can be applied to recognition of postcode information. The main objective of this article is to use the Radon Transformation parameter space to obtain an invariant set of character image features, on basis of which ...

Parameter extraction of HEMT models from multibias s-parameters

2009 IEEE International Symposium on Circuits and Systems, 2009
The aim of the paper is to show how to identify the parameters of various nonlinear circuit models of a high electron mobility transistor from the multibias s-parameter dataset measured on a pHEMT device. A three-step identification procedure is described that uses tested optimization methods.

Parameters affecting microwave‐assisted extraction of withanolides

Phytochemical Analysis, 2001
AbstractFocused microwave‐assisted extraction was applied to the extraction of three main withanolides from air‐dried leaves of Iochroma gesnerioides, namely, withaferin A, iochromolide and withacnistin. Six extraction variables, i.e. nature and volume of extracting solvent, sample moisture, extraction time, power of irradiation and particle size, were
