Loop fusion
Loop fusion, also called loop jamming, is a compiler optimization that merges two adjacent loops into one when semantics are preserved, reducing loop overhead and improving temporal data locality.
Loop heat pipe
A loop heat pipe (LHP) is a passive two-phase heat transport device driven by capillary forces, invented in the Soviet Union in the early 1980s and used for spacecraft thermal control.
Loop Industries
Loop Industries is a Canadian clean-technology company founded in 2014 in Terrebonne, Quebec, whose low-temperature methanolysis process breaks waste PET plastic back into monomers for new PET resin.
Loop optimization
Loop optimization is a set of compiler transformations that restructure a program's loops to improve speed or resource use, chiefly by increasing parallelism, improving memory locality, and enabling vectorization.
Loop shaping
Loop shaping is a feedback control design method in which the designer specifies a target open-loop gain profile and synthesizes a controller to match it, balancing performance and robustness.
Loop tiling
Loop tiling, also called loop blocking or cache blocking, is a program transformation that partitions a loop nest into tiles so cached data is reused before eviction.
Loop unrolling
Loop unrolling is a compiler optimization that replicates a loop body and adjusts iteration logic, reducing branch overhead and exposing instruction-level parallelism at the cost of code growth.
Loop-carried dependence analysis
Loop-carried dependence analysis is the compiler technique that determines whether a loop's iterations depend on earlier ones, deciding which loops can run in parallel or be vectorized.
Loopback
Loopback: a mechanism connecting a bidirectional telephony or data path back upon itself so transmitted signals return to the sender, used for fault sectionalization; defined in ITU-T M.125, with T1 ESF FDL codes, MPLS-TP RFC 6435, and H.248.85 variants.
LoopNet
LoopNet is an online marketplace for commercial real estate listings where brokers and owners advertise properties for sale or lease; founded in 1995, it was acquired by CoStar Group in 2012.
Loose cannon (nautical)
A loose cannon is a cannon that broke free of its ropes on a wooden warship and rolled dangerously about the deck, origin of the modern idiom.
Loose coupling
Loose coupling is a software design property in which components have little or no knowledge of each other's definitions, so changes to one component minimally affect others.
Lopal Technology (龙蟠科技)
Lopal Technology (龙蟠科技) is a Nanjing-headquartered chemicals company, founded in 2003, that makes lubricants, coolants, diesel exhaust fluid, and lithium iron phosphate battery cathode materials.
LoRa
LoRa, short for Long Range, is a proprietary chirp spread spectrum radio modulation technique for long-range, low-power wireless communication, developed by Cycleo and owned by Semtech.
LoRA (machine learning)
LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning technique for large language models in which frozen pre-trained weights are supplemented with small trainable low-rank matrices, introduced at Microsoft in June 2021.
LoRA adapters for generative media
LoRA (Low-Rank Adaptation) is a fine-tuning method, introduced by Microsoft in 2021, that freezes a pretrained model's weights and trains small low-rank update matrices instead.
LoRA fine-tuning ecosystem
LoRA (Low-Rank Adaptation) is a parameter-efficient fine-tuning method introduced by Microsoft researchers in 2021, which freezes a pre-trained model's weights and trains small low-rank adapter matrices instead.
LORAN
LORAN, short for Long Range Navigation, is a hyperbolic radio navigation system developed by the United States during World War II for ships and aircraft.
Loran Gas Field
The Loran Gas Field is an offshore natural gas field in Venezuela's Plataforma Deltana area, northeast of the Orinoco Delta, with about 7.3 trillion cubic feet of recoverable gas.
Loran-C
Loran-C was a pulsed radio navigation system at 100 kHz, operated by the US Coast Guard for marine and air navigation until GPS made it obsolete in 2010.
LoRaWAN
LoRaWAN, short for Long Range Wide Area Network, is a low-power wide-area protocol that connects battery-operated IoT devices over long distances, maintained by the LoRa Alliance.
Lord of the Isles (locomotive)
Lord of the Isles was a broad gauge 4-2-2 express locomotive of the Great Western Railway's Iron Duke class, designed by Daniel Gooch and built at Swindon in 1851.
Lordstown Motors
Lordstown Motors was an American electric vehicle manufacturer in Lordstown, Ohio, known for the Endurance electric pickup truck; it formed in 2020 and went bankrupt in June 2023.
Lorem ipsum
Lorem ipsum, also called dummy text, is filler placeholder text used in publishing, graphic design, and web development to demonstrate fonts and layout, derived from a mangled passage of Cicero.
Lorentz (company)
LORENTZ (Bernt Lorentz GmbH & Co. KG) is a German manufacturer of solar-powered water pumping systems, founded in Hamburg in 1993 and selling in about 140 countries.
