In order to ensure that linearity is achieved without decreasing efficiency, we propose to use a figure of merit based on DC power (PDC) and output power (Pout), which are measured using the power supply and a spectrum analyzer (EXA N9010A).
Single leg extension power will be measured using Nottingham power rig (University of Nottingham Medical School, Nottingham, UK) which has been tested for reliability and has a test retest co-efficient of variation (CV of 9.4%) [ 96] and in our laboratory the CV is 8% [ 97].
Transient characteristics, such as resistance variation and critical current of the 1 kA class HTS DC power cable were successfully measured using small power sources in the multi-terminal based test-bed.
ΦH2 = number of H2 molecules generated × 2/number of photons absorbed, which was evaluated from a change in the power of the transmitted light, measured using a power meter (Photo-Radiometer Model HD 2302.0 coupled with an irradiance measurement probe LP 471 RAD having an exposure window diameter of 1.6 cm) placed behind the cell parallel to the irradiation cell face.
The noise floor of the EEG recordings was measured using the power spectral density (Periodogram, with periods of excessively high artefact and recording pauses ignored), with average power in the 70 128 Hz band assumed to be indicative of noise.
Data on health care spending per capita are measured using "purchasing power parities" – that is, they are adjusted for international differences in the cost of living.
Figure 4 e) shows the passive power stability (for P = 8 and Q = 4) of the Airy (red line) and Gaussian (brown line) beam measured using a power meter.
AI662270, Magea, Xlr5, and Wfdc15a mRNA expression were measured using the Power SYBR Green PCR Master Mix (Applied Biosystems) in the StepOnePlus system (Applied Biosystems).
For example, he points out that "when measured using purchasing power parity, China and India each contributed more to global growth in 2007 than did the United States, the European Union and Japan".
The spectrum of the stimulus light was determined using a spectrophotometer (Ocean Optics USB2000), and the light intensity was measured using a power meter (Thorlabs S130VC).
