The phrase "at a high efficiency" is correct and usable in written English.
It can be used when discussing the effectiveness or performance level of a process, system, or machine.
Example: "The new engine operates at a high efficiency, reducing fuel consumption significantly."
Alternatives: "with high efficiency" or "at optimal efficiency".
Nanoparticle (NP) engineering, an alternative to genetic engineering, is similarly able to incorporate imaging labels on cells at a high efficiency while being less detrimental to the cell.
Additions of up to 3.5 × 10−3 M sodium fluoride had a negligible influence on the film growth, which occurred at a high efficiency.
Furthermore, a multifunctional meta-lens with broad bandwidth was designed and fabricated based on the Pancharatnam-Berry phase to converge or diverge incident Gaussian beams with different handedness at a high efficiency rate.
With predictive models, traffic states evolutions can be predicted, so VSL values can be optimized within model predictive control (MPC) frameworks to keep traffic flow at a high efficiency and suppress propagation of shockwaves, especially during congestion periods.
It ensures that the chiller plant operate at a high efficiency and the minimum annual total cost (including annual operational cost and annual capital cost) could be achieved under various possible cooling load conditions, considering the uncertain variables in cooling load calculation (i.e., weather conditions).
Results show that the control system is able to maintain output voltage from different power sources within a certain range, keep the state of charge of the batteries within an optimal range and meet power demand of the locomotive at a high efficiency.
The combination of coated particle fuel, inert helium gas as coolant and graphite moderated reactor makes possible to operate at high temperature yielding a high efficiency.
If combined with system operating at relatively low temperature, it represents a high efficiency solution for the heating of buildings.
It can also generate an energy consumption reduction if off peak charging of the thermal mass makes the mechanical equipment run at a higher efficiency.
The main feature of SOFC power systems is production of less harmful chemical and acoustic emissions at a higher efficiency compared to conventional power production technologies.
These integrated systems, known as polygeneration systems, produce electrical, heating and cooling at different conditions at a higher efficiency than a conventional system, and involve a wide range of technologies with several possible configurations.
