The Eighty Six H alpha Spectra from the Orion Nebula (M42, Sh2-281) with DEFPOS
(INDIAN ACAD SCIENCES, 2017-11-27)
In this study, eighty six H alpha (6563 angstrom) emission line spectra from the central region (similar to 40' x 40') of the Orion Nebula (NGC1976, M42, Sh2-281) have been obtained using DEFPOS spectrometer with a circular ...
Mean-square deviation analysis of the zero-attracting variable step-size LMS algorithm
(SPRINGER LONDON LTD, 2017-03)
The well-known variable step-size least-mean-square (VSSLMS) algorithm provides faster convergence rate while maintaining lower mean-square error than the conventional LMS algorithm. The performance of the VSSLMS algorithm ...
Histogram-Based Feature Extraction from Individual Gray Matter Similarity-Matrix for Alzheimer's Disease Classification
(IOS PRESS, 2017)
Automatic computer-aided diagnosis (CAD) systems have been widely used in classification of patients who suffer from Alzheimer's disease (AD). This paper presents an automatic CAD system based on histogram feature extraction ...
Mimicking speaker's lip movement on a 3D head model using cosine function fitting
(POLSKA AKAD NAUK, 2017-10)
Real-time mimicking of human facial movement on a 3D head model is a challenge which has attracted attention of many researchers. In this research work we propose a new method for enhancing the capturing of the shape of ...
Statistical approach based iris recognition using local binary pattern
(FEDERACION ASOCIACIONES INGENIEROS INDUSTRIALES ESPANA, 2017-01)
Among biometric features utilized for identity recognition purposes, iris has proven to be the most reliable one in terms of sufficient distinctiveness, which has direct implications and importance towards improving the ...
Multifunctionality of polypyrrole polyethyleneoxide composites: Concurrent sensing, actuation and energy storage
(MDPI AG, September )
In films of conducting polymers, the electrochemical reaction(s) drive the simultaneous variation of different material properties (reaction multifunctionality). Here, we present a parallel study of actuation-sensing-energy ...
(δ, 2)-Primary Ideals of a Commutative Ring
(Springer Science and Business Media Deutschland GmbH, December 2)
Let R be a commutative ring with nonzero identity, let I(R) be the set of all ideals of R and δ: I(R) → I(R) an expansion of ideals of R defined by I ↦ δ(I). We introduce the concept of (δ, 2)-primary ideals in commutative ...
Erratum to (δ, 2)-Primary Ideals of a Commutative Ring (Czechoslovak Mathematical Journal, (2020), 70, 4, (1079-1090), 10.21136/CMJ.2020.0146-19)
(Springer Science and Business Media Deutschland GmbH, December 2)
In Theorem 6 of [1], if R is a von Neumann regular ring, then every 2-prime ideal of R is a prime ideal. But the converse of this implication does not hold. Thus, we correct Theorem 6 of [1] as follows: Theorem 6. Let R ...
Comparison of different machine learning techniques on location extraction by utilizing geo-tagged tweets: A case study
(Elsevier Ltd, October 20)
In emergencies, Twitter is an important platform to get situational awareness simultaneously. Therefore, information about Twitter users’ location is a fundamental aspect to understand the disaster effects. But location ...
