A parametric technique for time delay estimation

ICASSP '82. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1984
Estimating the time-delay between two received signals is formulated as a parameter estimation problem for a certain spectral model. The model parameters are computed by a two step procedure: The modified Yule-Walker equations are used to estimate the autoregressive coefficients of the source signal, and a frequency domain squared error criterion is ...

Fiber-optic parametric amplifier and oscillator based on intracavity parametric pump technique

Optics Letters, 2009
A cost-effective fiber optical parametric amplifier (FOPA) based on the laser intracavity pump technique has been proposed and demonstrated experimentally. The parametric process is realized by inserting a 1 km highly nonlinear dispersion-shifted fiber (HNL-DSF) into a fiber ring-laser cavity that consists of a high-power erbium-doped fiber (EDF ...

Parametrization Techniques Applied to Filters Design

31st European Microwave Conference, 2001, 2001
This paper describes different numerical methods for filters design and parameterization. Each technique is used for establishing an accurate mathematical model that links the circuit electromagnetic (EM) performances to the structure studying parameters. The construction of such mapping between the circuit parameters and its response is started from a

Parametric Nonlinear Optical Techniques in Microscopy

2003
A small revolution is taking place in microscopy. Nonlinear optical spectroscopic techniques — which in bulk applications have been around almost since the invention of the laser in the sixties — are rapidly being incorporated within high resolution microscopy.

Parametric Ion-Exchange Processes (Parametric Pumping and Allied Techniques)

1986
The term “parametric pumping” implies the idea of pumping, that is of transport of material (in our case, ionic species) up along some potential scale (in our case, chemical potential), at the cost of degradation of some flux of energy (to be specified later).

Parametric techniques for concrete mixture design

2019 International Conference on Advances in Big Data, Computing and Data Communication Systems (icABCD), 2019
It is often a convectional approach by using a well-ordered factual technique to acquire an ideal proportioning of concrete blends. This is achieved by utilizing information obtained through a measurably arranged exploratory database. In this paper a complete exploratory approach is used to determine ideal concrete blends.

A non‐parametric class modelling technique

Journal of Chemometrics, 1989
AbstractA non‐parametric method for supervised pattern recognition is presented. The method is of the class modelling type, meaning that a classification rule is developed for each class, using the dissimilarities between the objects of the class. The dissimilarities between the objects within a class are related to the distances between all pairs of ...

Computational techniques for processing parametric surfaces

Computer Vision, Graphics, and Image Processing, 1984
This paper presents computational techniques using which subdivision algorithms may be devised for the processing (rendering, intersection detection, silhouette detection) of parametrically defined surfaces. These algorithms work by subdividing surface patches until they are simple enough for direct handling.

Parametric technique for P wave delineation

Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002
The electrocardiogram (ECG), which represents the electrical activity of the heart, is widely used for the diagnosis of cardiac diseases. The ECG typically consists of three important component waves, called the P, QRS, and T waves, which provide clinical information about the functioning of the heart.
