The phrase "at substantial performance" is correct and usable in written English.
It is typically used in legal or contractual contexts to indicate that a party has fulfilled a significant portion of their obligations under a contract, even if not all conditions have been met.
Example: "The contractor is entitled to payment at substantial performance of the project, despite minor deficiencies that need to be addressed."
Alternatives: "upon significant completion" or "at major fulfillment".
In the fourth experiment (i.e., beamforming and interference cancellation being applied), a very little performance gain is noticed with S-TDD and D-TDD compared to the third experiment; IBFD, nevertheless, experienced a substantial performance gain, especially at high number of active MSs as demonstrated in Fig. 11.
In single test cells these materials generated output powers near 900 mW/cm−2 at 850 °C using pure H2 as fuel, and demonstrated substantial performance with CH4.
The lack of substantial performance improvement for the infiltrated samples at suitable cell voltages was attributed to two factors: the relatively low nanoparticle loading and the relatively small contribution to total loss from the anode polarisation resistance.
This resulted in substantial performance deterioration when they tested the model at another location.
Today he will give a more substantial performance.
Elizabeth Van Dyke offers the broadest and least substantial performance as Annie, the churchgoer who becomes a temptress.
With even a single (re transmission round, substantial performance improvement is achieved by the HARQ schemes, compared to the case with no CSI at the BSs.
Substantial performance gains have been observed in simulations.
Adaptive resource allocation has been shown to provide substantial performance gain in OFDMA-based wireless systems, such as WiMAX, when full channel state information (CSI) is available at the transmitter.
The proposed RAID scheme was shown to achieve substantial performance gains compared to the common detection scheme which neglects the reliability of the transmission on the first hop and implicitly assumes perfect decoding at the relays.
