A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power ...
The Canadian weather radar network consists of 33 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each had until 2018 a range of 256 km (159 mi) in radius around the site to detect reflectivity, 3 angles with a range ...
Varian Associates. Varian Associates was one of the first high-tech companies in Silicon Valley. It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.
Renewable energy portal. v. t. e. Solar power forecasting is the process of gathering and analyzing data in order to predict solar power generation on various time horizons with the goal to mitigate the impact of solar intermittency. Solar power forecasts are used for efficient management of the electric grid and for power trading.
A traveling-wave tube ( TWT, pronounced "twit" [1]) or traveling-wave tube amplifier ( TWTA, pronounced "tweeta") is a specialized vacuum tube that is used in electronics to amplify radio frequency (RF) signals in the microwave range. [2] It was invented by Andrei Haeff around 1933 as a graduate student at Caltech, and its present form was ...
The European Centre for Medium-Range Weather Forecasts ( ECMWF) is an independent intergovernmental organisation supported by most of the nations of Europe. It is based at three sites: Shinfield Park, Reading, United Kingdom; Bologna, Italy; and Bonn, Germany. It operates one of the largest supercomputer complexes in Europe and the world's ...
While day-ahead forecasts can take advantage of autoregressive effects, forecasts featuring meteorological data are more accurate for 2-4 day-ahead horizons. In some cases, renewable energy generation forecasts published by Transmission System Operators (TSOs) can be improved with simple prediction models and used provide more accurate ...
8. Sheet Pan French Toast. Just like pancakes, you can also make french toast on a baking sheet in the oven to save tons of time. This recipe is a decadent version with cinnamon, vanilla, and ...
