The gauge performances are investigated inside a turbo vacuum system with 10−11 Torr background vacuum, and the pressure is calibrated against a commercial IE 514 extractor gauge.
Huang et al. replaced thermionic filament of the Bayard-Alpert gauge (BAG) by a line-type CNT cathode, and the gauge performances were studied from 10−4 to 10−7 Torr with the sensitivity of 3.6 Torr−1 [18].
However, the single best gauge of economic performance is not growth in GDP, but GDP per person, which is a rough guide to average living standards.
In any case, a better gauge of productivity performance is total factor productivity (TFP), which measures the overall efficiency with which inputs of both labour and capital are used.
It is also worth noting that the British economy, which has done the most to copy America, has grown more slowly than either Germany or France over the past decade.The second gauge of economic performance is productivity, an area in which America, it is claimed, is enjoying a miracle.
There's also a new Basis Peak Playground area in the app, where users can try out a new Location feature to see where they did each of their workouts, and a Photo Finish feature where you take a selfie at the end of your run to gauge how your performance is affecting things like mood over time.
The real gauge of Schumacher's performance is a comparison with his team-mate, Nico Rosberg.
Another way to gauge a firm's performance is to take everything it possesses — its buildings, its machinery and other equipment, its product designs, and its financial holdings — and look at how much profit it generates for each dollar of assets on its books.
The second way to gauge a model's performance is out-of-sample tests, where the fit to other time periods (or other empirical contexts more generally) is used as a test of the model.
