Power-line Interference Removal from High Sampled ECG Signals Using Modified Version of the Subtraction Procedure [PDF]

International Journal Bioautomation, 2020
The acquired ECG signals are often contaminated by residual Power-line Interference (PLI). A lot of methods, algorithms and techniques for PLI reduction have been published over the last few decades.

Cutoff wavenumber analysis of arbitrarily shaped waveguides using regularized method of fundamental solutions with excitation sources

Electronics Letters, 2023
The method of fundamental solutions with excitation source (MFS‐ES) is a reliable method for determining the eigenvalues of a two‐dimensional hollow waveguide. However, the accuracy in MFS‐ES is extremely dependent on the choice of the auxiliary boundary.

Numerical analysis of microwave detection of breast tumours using synthetic focussing techniques [PDF]

, 2004
Microwave detection of breast tumours is a non-ionising and potentially low-cost and more certain alternative to X-ray mammography. Analogous to ground penetrating radar (GPR), microwaves are transmitted using an antenna array and the reflected signals ...

Semi-blind speech-music separation using sparsity and continuity priors [PDF]

, 2010
In this paper we propose an approach for the problem of single channel source separation of speech and music signals. Our approach is based on representing each source's power spectral density using dictionaries and nonlinearly projecting the mixture ...

Surface Terms as Counterterms in the AdS/CFT Correspondence [PDF]

, 1999
We examine the recently proposed technique of adding boundary counterterms to the gravitational action for spacetimes which are locally asymptotic to anti-de Sitter.

The Algebraic Method [PDF]

, 2001
Combining the effect of an intermediate renormalization prescription (zero momentum subtraction) and the background field method (BFM), we show that the algebraic renormalization procedure needed for the computation of radiative corrections within non ...

GPI PSF subtraction with TLOCI: the next evolution in exoplanet/disk high-contrast imaging

, 2014
To directly image exoplanets and faint circumstellar disks, the noisy stellar halo must be suppressed to a high level. To achieve this feat, the angular differential imaging observing technique and the least-squares Locally Optimized Combination of ...

Realizing arbitrary-precision modular multiplication with a fixed-precision multiplier datapath [PDF]

, 2009
Within the context of cryptographic hardware, the term scalability refers to the ability to process operands of any size, regardless of the precision of the underlying data path or registers.

A Search for Cosmic Microwave Background Anisotropies on Arcminute Scales with Bolocam [PDF]

, 2008
We have surveyed two science fields totaling one square degree with Bolocam at 2.1 mm to search for secondary CMB anisotropies caused by the Sunyaev- Zel'dovich effect (SZE). The fields are in the Lynx and Subaru/XMM SDS1 fields.
