Power Control Optimization of an Underwater Piezoelectric Energy Harvester
(MDPI, 2018-03)
Over the past few years, it has been established that vibration energy harvesters with intentionally designed components can be used for frequency bandwidth enhancement under excitation for sufficiently high vibration ...
Analysis of New Strategies to Reach Nearly Zero Energy Buildings (nZEBs)
(MDPI, 2018-11-07)
The need to reduce CO2 emissions makes it necessary to review most areas of human activity because we are the main source of these emissions. In particular, the building sector is one of its main responsible. Through a ...
5 MW Wind Turbine Annual Energy Production Improvement by Flow Control Devices
(MDPI, 2018-11-06)
Several flow control devices have been studied in recent years. Majority of them were designed firstly for aeronautical purposes. At present many research is aimed to introduce these devices in wind turbines (WTs) in order ...
Gurney Flap Implementation on a DU91W250 Airfoil
(MDPI, 2018-11-06)
Abstract
The increasing capability of Wind Turbine (WT) based power generation systems has derived in an increment of the WT rotor diameter, i.e., longer rotor blades. This results in an increase of the electrical power ...
Genetic and environmental factors affecting birth size variation: a pooled individual-based analysis of secular trends and global geographical differences using 26 twin cohorts
(Oxford University Press, 2018-05-19)
Background: The genetic architecture of birth size may differ geographically and over
time. We examined differences in the genetic and environmental contributions to birthweight,
length and ponderal index (PI) across ...
