Mitigation of Harmonics and Inter-Harmonics with LVRT and HVRT Enhancement in Grid-Connected Wind Energy Systems Using Genetic Algorithm-Optimized PWM and Fuzzy Adaptive PID Control
(2021-03-28)
The growing installed wind capacity over the last decade has led many energy regulators to define specific grid codes for wind energy generation systems connecting to the electricity grid. These requirements impose strict ...
A Laplace Transform Finite Difference Scheme for the Fisher-KPP Equation.
(2021-03-28)
This paper proposes a numerical approach to the solution of the Fisher-KPP reaction-diffusion equation in which the space variable is developed using a purely finite difference scheme and the time development is obtained ...
How to re-engage older adults in community sport? Reasons for drop-out and re-engagement
(2021-03-27)
Internationally, many sport policies articulate a desire for lifelong participation in sport. However, participation often fluctuates throughout the life span and most people drop-out at some stage. Most research on drop ...
Beyond HRV. Extending the range of autonomic measures associated with heart rate variability – the effects of transcutaneous electroacupuncture (TEAS)
(2021-03-27)
Background: Heart rate variability (HRV) is useful in acupuncture research as a measure of autonomic response. However, although it accurately reflects parasympathetic activity, there is less agreement on whether and how ...
Resolving Fast Gas Transients with Metal Oxide Sensors
(2021-03-26)
Electronic olfaction can help detect and localize harmful gases and pollutants, but the turbulence of the natural environment presents a particular challenge: Odor encounters are intermittent, and an effective electronic ...
The VANDELS ESO public spectroscopic survey : Final Data Release of 2087 spectra and spectroscopic measurements
(2021-03-26)
VANDELS is an ESO Public Spectroscopic Survey designed to build a sample of high signal to noise, medium resolution spectra of galaxies at redshift between 1 and 6.5. Here we present the final Public Data Release of the ...
Analysis of physical processes in eruptive YSOs with near infrared spectra and multi-wavelength light curves
(2021-03-26)
The decade-long Vista Variables in the Via Lactea (VVV) survey has detected numerous highly variable young stellar objects (YSOs). We present a study of 61 highly variable VVV YSOs (Delta Ks = 1-5 mag), combining near ...
Antithrombotic therapy in diabetes: Which, when, and for how long?
(2021-03-25)
Cardiovascular disease remains the main cause of mortality in individuals with diabetes mellitus (DM) and also results in significant morbidity. Premature and more aggressive atherosclerotic disease, coupled with an enhanced ...
From training wheels to chemical condoms: exploring the narratives of PrEP discontinuation
(2021-03-24)
This paper explores experiences of PrEP, a HIV-prevention intervention, among bugchasers, gay men who eroticize HIV. While PrEP has been hailed as a “game changer” in HIV-prevention, little attention has been paid to why ...
