The last two are shown experimentally to outperform the currently most efficient ones in area, delay and dynamic power dissipation terms.
They fly in patterns calculated ahead of time to be the most efficient, spraying at problem areas when they're over them, and returning to the ground stations to have power supplies swapped out before returning to the pattern.
China is already buying and installing the world's most efficient transmission lines — "an area where China has actually moved ahead of the U.S.," according to Deborah Seligsohn, a senior fellow at the World Resources Institute.
For computing the volume of fluid in an arbitrary polygonal or polyhedral fluid element, we also cite some of the most efficient formulas for polygon area and polyhedron volume computations.
Yttrium oxide with a space group Ia3 (No. 206) and cubic crystal structure, density of about 5.01 g/cm3, refractive index more than 1.9, a wide band gap of 5.8 eV and melting point over 2400 °C has been known as one of the most efficient phosphors in the area of optic materials.
Installation of NHP could be the most efficient arsenic mitigation intervention in areas where the population is scarce and illiterate.
Further, the most efficient method of inoculating large areas was by aerial spraying, a procedure that not only entailed higher cost but that would also face regulatory uncertainties over spraying GM bacteria.
At this high level of soil moisture, large tussocks (>60 cm in diameter), which were sexually mature and had a large leaf surface area, were the most efficient with regard to daily water use efficiency (whole plant net photosynthesis/whole plant transpiration).
Relascope plots were most efficient for volume and basal area, but not as efficient for stems per ha.
The sensor with washed sand as porous medium was found to be the most efficient one for the study area.
