The phrase "as the reference system" is correct and usable in written English.
It can be used when discussing a framework or basis for comparison in various contexts, such as scientific, mathematical, or technical discussions.
Example: "In our analysis, we will use the Earth as the reference system to measure the gravitational forces acting on the satellite."
Alternatives: "as the basis for comparison" or "as the frame of reference."
This is considered as the reference system.
The methodology includes the comparison of two scanning technologies, laser scanning and contact scanning, considering the latter one as the reference system.
This degradation is however almost completely mitigated using the code-aided approach, yielding essentially the same FER performance as the reference system.
Coal gas life cycle is used as the reference system for comparison with that of coconut shell-derived producer gas life cycle.
For the air conditioner in room D, which was chosen as the reference system, only the first phase of monitoring, without any sanitization treatment, was performed.
Small-subunit ribosomal RNA has been used as the reference system for generating species tree [ 25] in many studies because of the central role it holds in the fundamental process of translation and also due to it slow rate of evolution [ 56].
For pilot-based estimation, the MAP algorithm is slightly better than the LMMSE algorithm in terms of FER and outperforms the ML algorithm by about 0.8 dB; as compared to the reference system, the FER resulting from MAP estimation is about 2.2 dB worse.
When exploiting only the pilot symbols for channel estimation, the MAP approach slightly (by about 0.2 dB) outperforms the LMMSE and ML approaches in terms of FER; as compared to the reference system, the FER resulting from MAP estimation is about 2 dB worse.
Selecting the object's center of mass as the origin of the reference system is coherent with the system dynamics, but as stated above for other measures, in some cases it may be difficult to know the center of mass accurately.
The ionospheric electron density peak height of the F2 region, hmF2, and the effective scale height at the hmF2, Hm, deduced from average profiles have been analyzed to obtain the quiet-time behavior and have been analytically modeled by the spherical harmonic analysis (SH) technique using the modip latitude as the coordinate of the reference system.
Low-cost drugs, defined as those drugs included in the reference system and not incurring a reference supplement for the patient, are thus generic drugs but also brand name original products that lowered their price to the reference price.
