A Step-Down ZVS Power Converter with Self-Driven Synchronous Rectifier
(IEEE, 2021-04-27)
In this paper a step-down ZVS power converter with a self-driven synchronous rectifier (SDSR) for a low-voltage high-current applications is proposed. A transformer leakage inductance, a resonant capacitor and a diode make ...
Prediction of steady-state two-phase flow of nitrogen + extinguishant in the pipeline and a correlation for mass flow rate
(2021-04-27)
Nitrogen used for pressurization of a fire extinguisher could be partially dissolved in the fire extinguishing agent, forming a binary mixture accompanied by a phase change while flowing inside the pipeline. Notwithstanding ...
Identification of TV Channel Watching from Smart Meter Data Using Energy Disaggregation
(2021-04-27)
Smart meters are used to measure the energy consumption of households. Specifically, within the energy consumption task, a smart meter must be used for load forecasting, the reduction in consumer bills as well as the ...

Measurement of the 72Ge(n,γ) cross section over a wide neutron energy range at the CERN n_TOF facility
(2021-04-27)
The Ge72(n,γ) cross section was measured for neutron energies up to 300keV at the neutron time-of-flight facility n_TOF (CERN), Geneva, for the first time covering energies relevant to heavy-element synthesis in stars. The ...
A history of high-power laser research and development in the United Kingdom
(2021-04-27)
The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different materials, operating at different ...
Ethnic differences in out-of-hospital cardiac arrest among Middle Eastern Arabs and North African populations living in Qatar
(2021-04-26)
Aims: There are very few studies comparing epidemiology and outcomes of out-of-hospital cardiac arrest (OHCA) in different ethnic groups. Previous ethnicity studies have mostly determined OHCA differences between African ...
Availability of Illegal Drugs During the COVID-19 Pandemic in Western Germany
(2021-04-23)
Background: In response to the COVID-19-pandemic, a lockdown was established in the middle of March 2020 by the German Federal Government resulting in drastic reduction of private and professional traveling in and out of ...
The use and context of the term “multimorbidity” in rheumatoid arthritis: a systematic literature review
(2021-04-23)
This systematic literature review aimed to analyse terms describing coexisting conditions in the RA literature, informing the need for an operationalized definition of multimorbidity. Articles discussing RA with multimorbidity, ...
