Simulation of Wind-Battery Microgrid Based on Short-Term Wind Power Forecasting

open access: yesApplied Sciences, 2017
The inherently intermittent and highly variable nature of wind necessitates the use of wind power forecasting tools in order to facilitate the integration of wind turbines in microgrids, among others.

Comparison of mathematical and comparative slaughter methodologies for determination of heat production and energy retention in broilers

open access: yesPoultry Science, 2020
Understanding factors affecting ME availability for productive processes is an important step in optimal feed formulation. This study compared a modelling methodology with the comparative slaughter technique (CST) to estimate energy partitioning to heat ...

Evaluating and predicting net energy value of wheat and wheat bran for broiler chickens [PDF]

open access: yesAnimal Bioscience, 2022
Objective It is crucial to accurately determine the net energy (NE) values of feed ingredients because the NE system is expected to be applied to the formulation of broilers feed. The NE values of 5 wheat and 5 wheat brans were determined in 12-to 14-day

Charged particle interaction with a chirped electromagnetic pulse [PDF]

open access: yes, 2003
It is found that a charged particle can get a net energy gain from the interaction with an electromagnetic chirped pulse. Theoretically, the energy gain increases with the pulse amplitude and with the relative frequency variation in the ...

Metabolizable and net energy values of corn stored for 3 years for laying hens

open access: yesPoultry Science, 2020
The apparent metabolizable energy (AME), AME corrected to zero-nitrogen retention (AMEn), and net energy (NE) values of 2 corn samples both stored for 3 yr were determined in laying hens with reference diet substitution method.

Net Energy Index: A New Way To Measure Energy Efficient Buildings [PDF]

open access: yes, 2020
Energy efficiency indexes are useful for providing tangible measurements of energy efficiency in buildings. Buildings use approximately 70% of all electricity in the USA.

Classification of subsystems for graded-local nets with trivial superselection structure [PDF]

open access: yes, 2003
We classify Haag-dual Poincar\'e covariant subsystems $\B\subset \F$ of a graded-local net $\F$ on 4D Minkowski spacetime which satisfies standard assumptions and has trivial superselection structure. The result applies to the canonical field net $\F_\A$

Evaluation of the Equations to Predict Net Energy Requirement for Lactation in the Cattle Feeding System: Based on the Literature Database

open access: yesAgriculture, 2022
The net energy requirement for lactation (NEL) equals the milk energy, which is the sum of the energy content from the energy-yielding nutrients in milk. The specific nutrients and their calories, however, vary depending on the feeding system.

Magnetic heating across the cosmological recombination era: Results from 3D MHD simulations [PDF]

open access: yes, 2018
The origin of cosmic magnetic fields is an unsolved problem and magnetogenesis could have occurred in the early Universe. We study the evolution of such primordial magnetic fields across the cosmological recombination epoch via 3D magnetohydrodynamic ...

Design of a 130 MW Axial Turbine Operating with a Supercritical Carbon Dioxide Mixture for the SCARABEUS Project

open access: yesInternational Journal of Turbomachinery, Propulsion and Power
Supercritical carbon dioxide (sCO2) can be mixed with dopants such as titanium tetrachloride (TiCl4), hexafluoro-benzene (C6F6), and sulphur dioxide (SO2) to raise the critical temperature of the working fluid, allowing it to condense at ambient ...
