Dynamic photovoltaic greenhouse: Energy efficiency in clear sky conditions
Applied Energy, 2016Abstract This paper assesses the energy efficiency of a prototype of a dynamic photovoltaic (PV) greenhouse that has an asymmetric cross section and allows the rotation of the PV modules around their longitudinal axis throughout the day to select the degree of shading inside the structure.

Energy Dissipation Within Intermittent Clear Air Turbulence Patches
Journal of the Atmospheric Sciences, 1977Abstract Mean dissipation rates of kinetic energy in the lower stratosphere are estimated from data obtained with an instrumented, superpressure, constant-level balloon launched to measure the vertical wind shear at 200 mb. The flight record shows that while the balloon was located above a mountainous region localized patches of turbulence were ...

Forecast for nuclear energy: Clear skies or stormy weather?
AIP Conference Proceedings, 2018During the last decade many people in the nuclear industry were forecasting a renaissance in construction of nuclear power plants, especially in light of the near-zero greenhouse gas emissions of nuclear power and the global need for such cleaner electricity sources.

On the Energy Supply of Clear Air Turbulence
1969The amount of kinetic energy observed in clear air turbulence suggests strongly that under certain conditions stable atmospheric layers contain kinetic energy that may be released into turbulence once turbulence has been triggered. The analogy that comes to mind is the potential energy released in clouds. The atmosphere may be stable until condensation

Clear evidence for the spin-wave energy gap in terbium
Journal of Low Temperature Physics, 1969Our electrical resistivity measurements on single-crystal terbium oriented along the c-axis clearly show the spin-wave energy gap at 21.5°K. The total resistivity fits the equation ρ=ρ0+2.43×10−7T5+2.544×10−3T2 exp(21.5/T) µΘ-cm in the temperature region below 21.5°K.

Security-Constrained Joint Market Clearing of Energy and Reserves Auctions
Australian Journal of Electrical and Electronics Engineering, 2009This paper proposes a model of security-constrained joint market clearing of energy and reserves (AGC, spinning, non-spinning and operating reserves) auctions. The model takes into consideration lost opportunity cost (LOC) and multi-block offers in the market clearing framework.

Large Scale Processes Contributing Energy to Clear Air Turbulence
1969The significance of the Richardson number for existing turbulence is examined and is shown to be more appropriately a comparative measure of the importance of terms in the energy budget rather than a criterion for the growth or decay of turbulence. Data from the literature is examined to show that there must be a continued input of energy from large ...

Beam Energy Forecasting using Machine Learning at the CLEAR accelerator
In particle accelerators, accurate and stable beam parameters are crucial for experimental success. Traditional methods for measuring parameters like beam energy often rely on invasive techniques that disrupt experiments. This paper presents a novel, non-invasive machine learning-based approach to predict beam energy using parasitic measurements ...Gilardi,Antonio +19 more
