Low-rank compression represents a large model weight matrix as the product of two much smaller matrices; LoRA serving runs many such adapters over one shared base model.
Low-temperature ammonia decomposition catalysts
Low-temperature ammonia decomposition catalysts are materials that split ammonia into hydrogen and nitrogen below about 450 °C for on-site hydrogen generation, with ruthenium the most active metal and nickel the leading cheaper alternative.
Low-temperature co-fired ceramic
Low-temperature co-fired ceramic (LTCC) is a multilayer substrate technology in which printed glass-ceramic tape layers are stacked and co-fired at 800–900 °C with conductive metals.
Low-temperature silver paste
A low-temperature silver paste is a screen-printable conductive ink cured near 200 °C, used for metallizing silicon heterojunction solar cells whose amorphous layers tolerate little heat.
Low-voltage differential signaling
Low-voltage differential signaling (LVDS) is a differential electrical signaling standard introduced in 1994 for high-speed, low-power transmission of binary data over copper at rates up to 655 Mbit/s.
Low-voltage direct current
Low-voltage direct current distributes electrical power as direct current at low voltages, typically 48 to 800 volts, avoiding repeated AC-to-DC conversions in buildings, data centers, telecommunications, and microgrids.
Lowboy trailer
A lowboy trailer is a semitrailer with two deck drops forming a low central well, 18 to 24 inches off the ground, for hauling tall, heavy equipment within legal height limits.
