"fixed source" is correct and usable in written English.
You can use it to refer to a source of something that is known and reliable, and that doesn't change over time. For example, "Many people rely on their salary as a fixed source of income."
At a fixed source temperature and a fixed sink temperature, the optimal engine performance can be obtained by the method of Lagrange multipliers.
Selection of the matrix image of each character can be done either by using a mobile support for the matrices (plastic tape, disk, drum) in front of a fixed source for the beam of light or by using a mobile beam of light in front of a fixed support for the matrices (glass or plastic plate); alignment of type pieces is carried out in either case by mobile prisms or mirrors.
However, the fusion blanket design is a fixed source problem.
However, this conclusion only applies to the fixed source problem.
We tested eight locations of the fixed source at intervals of 10° from 0° to 70°.
For the fixed source position, we used a discrete uniform distribution on the 50 × 50 lattice.
The only ultimate solution for the problem of night driving is the one adopted for interior use: to provide sufficient illumination from fixed sources so that entire areas are brightly lighted.
Strong suppression of the source-drain current in the Coulomb blockade oscillation region (between the dashed lines) with a fixed source-drain voltage VSD = 20 mV at T = 1.41 K is observed.
Example of the AD of the proposed (temporal mean) DRR estimate (19) [dB] (solid circled line) compared to the AD of Jeub et al.'s CDR-based (temporal mean) DRR estimate [dB] (dashed asterisk line), versus SNR level [dB], with fixed T 60=0.3 s and fixed source-microphone distance =0.5 m.
The area in and surrounding Gladstone, Rockhampton, Stanwell and Callide ("Gladrock") in Central Queensland Australia emits over 40.5 million tonnes (Mt) of carbon dioxide (CO2) from fixed sources every year.
Organic carbon (OC) from the terrestrial ecosystem generally has a steady composition and fixed sources and it is an important carbon source for the aquatic biological processes.
