Reduced contribution of a nonsimultaneous mistuned harmonic to residue pitch: The role of harmonic number [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2009
Listeners adjusted a matching sound so that its pitch equaled that of a subsequent 90-ms complex tone (12 harmonics of a 155-Hz F0), whose mistuned harmonic (±3%) was presented either simultaneously with or after the other harmonics. The third or the fourth harmonic was mistuned.

Real-Time Harmonic Pollution Evaluation Considering Multiple Dynamic Customers

open access: yesCSEE Journal of Power and Energy Systems
The widespread deployment of renewable energies and non-linear loads has led to serious harmonic pollution in electrical distribution networks. Evaluation of the harmonic contribution (HC) of each customer is a significant task for power quality ...

Global Harmonic Parameters for Estimation of Power Quality Indices: An Approach for PMUs

open access: yesEnergies, 2020
For wide-area measurement systems and smart grids, phasor measurement units (PMUs) have become key elements since they provide synchronized information related to the fundamental frequency components of voltages and currents.

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Construction of nonlocal light-cone operators with definite twist

open access: yes, 1999
A systematic procedure is introduced to uniquely decompose nonlocal LC-operators into harmonic operators of well defined geometric twist. The method will be demonstrated for (pseudo)scalar, (axial) vector and skew tensor bilocal quark light-ray ...

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...
