Estimation of the Latent Heat Flux over Irrigated Short Fescue Grass for Different Fetches

open access: yesAtmosphere, 2021
Often in agrometeorology the instrumentation required to estimate turbulent surface fluxes must be installed at sites where fetch is not sufficient for a sector of wind directions.

Power Transformer Inrush Current Analysis: Simulation, Measurement and Effects

open access: yesApplied Sciences
Inrush current is still a persistent problem affecting the quality of the power system. This paper presents the theoretical aspects of this transient phenomenon, the simulation of the phenomenon for prediction purposes and its measurement in a test ...

Impact of post-field data processing on eddy covariance flux estimates and energy balance closure

open access: yesMeteorologische Zeitschrift, 2006
This study evaluates the impact of post-field data processing methods on eddy covariance flux estimates and the resulting energy balance residual. To that end, a dataset from the LITFASS-2003 field campaign was analysed using an experimental software ...

XMM-Newton observations of EF Eridani: the textbook example of low-accretion rate polars [PDF]

open access: yes, 2007
Archival X-ray observations of EF Eridani obtained in a low state revealed distinct X-ray detections at a luminosity L_X ~ 2 10^{29} erg/s, three orders of magnitude below its high state value. The plasma temperature was found to be as low as $kT \loa 2$

Prediction of Transformer Residual Flux Based on J-A Hysteresis Theory

open access: yesEnergies
Circuit breakers are effectively utilized for the controlled switching technique to mitigate inrush current when energizing an unloaded transformer. The core of the controlled switching technique is to obtain the appropriate closing angle based on the ...

Use of ornamental rock residues for mould flux development [PDF]

open access: yesREM - International Engineering Journal, 2018
Abstract Ornamental rock production, such as marble and granite plates, have great importance in the southeastern region of Brazil. Its residues are composed of some compounds used in continuous casting as mould fluxes. Therefore, the aim of this article was to study these residues to formulate mould fluxes.

A large-eddy simulation exploration of the assumptions used in retrieving entrainment from a mixing diagram approach with ground-based remote sensors [PDF]

open access: yesAtmospheric Measurement Techniques
Entrainment is a crucial component of the atmospheric boundary layer (BL) moisture and heat budget. While usually thought of as only entrainment flux, entrainment within the mixed layer budget equation is really composed of two terms: the flux of a ...

Residual conductance of correlated one-dimensional nanosystems: A numerical approach

open access: yes, 2004
We study a method to determine the residual conductance of a correlated system by means of the ground-state properties of a large ring composed of the system itself and a long non-interacting lead.

Impurity dominated thin film growth [PDF]

open access: yes, 2018
Magnetron sputter deposition was applied to grow thin metal films in the presence of impurities. These impurities are ambient gas molecules and/or atoms from the residual gas present in the vacuum chamber.

The HIT Network for Children and Adolescents With CNS Tumors Facilitates Improvements of Diagnostic Assessments, Multimodal Treatments, Individual Counseling, and Research in Germany, Austria, and Switzerland

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The HIT network was established in 2000 to create a population‐based structure aiming to improve survival rates and reduce late effects for children with central nervous system (CNS) tumors by conducting comprehensive clinical trials.
