Wavelet Denoising Based on the MAP Estimation Using the BKF Prior With Application to Images and EEG Signals
( IEEE , 2013 , Article)This paper presents a novel nonparametric Bayesian estimator for signal and image denoising in the wavelet domain. This approach uses a prior model of the wavelet coefficients designed to capture the sparseness of the ... -
Wavelet Transform with Histogram-Based Threshold Estimation for Online Partial Discharge Signal Denoising
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)Online condition assessment of the power system devices and apparatus is considered vital for robust operation, where partial discharge (PD) detection is employed as a diagnosis tool. PD measurements, however, are corrupted ... -
Wavelet-based Encoding Scheme for Controlling Size of Compressed ECG Segments in Telecardiology Systems
( Springer New York LLC , 2017 , Article)One of the major issues in time-critical medical applications using wireless technology is the size of the payload packet, which is generally designed to be very small to improve the transmission process. Using small packets ... -
Wavelet-based multiscale filtering of genomic data
( IEEE Computer Society , 2012 , Conference Paper)Measured biological data are a rich source of information about the biological phenomena they represent. For example, time-series genomic or metabolic microarray data can be used to construct dynamic genetic regulatory ... -
A wavelet-based passive islanding detection technique
( IEEE , 2012 , Conference Paper)Distribution power systems are radial in nature. Power flows in one direction from the utility to the load. Most protection, monitoring, and control devices are designed based on this unidirectional flow of power. Distributed ... -
A Way Forward for Ethics Education in Business: A Case from the Middle East
( NeilsonJournals Publishing , 2017 , Article)The objective of this study is to review the performance of business students in ethics assessments and suggest enhancements to the ethics curriculum. Data triangulation method was used to gather the data. First, data ... -
The Way We See It: Poetic-Visual Reciprocity in Egyptian Street Art Since 2011
( Brill , 2022 , Article)This article traces the manifestations of the newly adapted artistic form of “calligraffiti,” or the synthetic braiding of poetry and graffiti on what became known as the “walls of protest” in post-2011 Egypt. This new ... -
We work together as a group': implications of jigsaw cooperative learning
( BioMed Central Ltd , 2023 , Article)Background: Modern clinical practice increasingly relies on collaborative, cooperative and team-based approaches for effective patient care. Recently, Jigsaw cooperative learning has gained attention in medical education. ... -
Weak and strong convergence theorems for generalized nonexpansive mappings
( Universitatii Al.I.Cuza din Iasi , 2016 , Article)We consider a class of generalized nonexpansive mappings introduced by Karapinar and seen as a generalization of Suzuki (C)-condition. We prove some weak and strong convergence theorems for approximating fixed points of ... -
Weak and strong convergence theorems without some widely used conditions
( Academic Publications, Ltd. , 2010 , Article)We establish weak (strong) convergence of Ishikawa iterates of two asymptotically (quasi-)nonexpansive maps without any condition on the rate of convergence associated with the two maps. Moreover, our weak convergence ... -
Weakly Conjugated Hybrid Zinc Porphyrin Sensitizers for Solid-State Dye-Sensitized Solar Cells
( Wiley-VCH Verlag , 2016 , Article)Molecularly engineered weakly conjugated hybrid porphyrin systems are presented as efficient sensitizers for solid-state dye-sensitized solar cells. By incorporating the quinolizino acridine and triazatruxene based unit ... -
WEALTH AND THE PERSISTENCE OF AUTHORITARIANISM IN THE GULF STATES: ECONOMIC PRIVILEGE OR A CULTURAL PHENOMENON?
( Foundation for Good Politics , 2021 , Article)During the Arab Spring the idea of the Middle East as an authoritarian exception appeared to be no longer valid. Yet the Gulf states seem to be safe from political turmoil. This paper examines the persistence of authoritarianism ... -
Wear resistance investigation of titanium nitride-based coatings
( Elsevier Ltd. , 2015 , Article)The wear of components while they are in service is a predominant factor controlling the life of machine components. Metal parts are often damaged because of wear-driven failures causing the loss of dimensions and ... -
Wear, optimization and surface analysis of Al-Al2O3-TiO2 hybrid metal matrix composites
( SAGE Publications Ltd , 2021 , Article)The aim of the present work is to investigate vickers hardness, wear behavior as well as to perform optimization of wear data for pure Al and Al-Al2O3-TiO2 hybrid metal matrix composites. The hybrid composite (Al-Al2O3-TiO2) ... -
Wearable Devices to Revolutionize Health Care
( UC Regents , 2022 , Other)In the last decade, we witnessed a rapid growth of wearable devices—small electronic devices that are worn or carried on the human body. A study by the Facts and Factors found that the global Wearable device market size ...
