Lattice filter
A lattice filter is a digital filter structure built from identical cascaded stages, each defined by one reflection coefficient, used in speech processing and adaptive filtering.
Lattice metamaterials
Lattice metamaterials are artificial cellular materials built from a periodic arrangement of struts, plates, or shells, with mechanical properties set by unit cell geometry rather than base material composition.
Lattice physics calculation
A lattice physics calculation is a neutron transport and fuel depletion computation on a 2D fuel assembly slice, producing few-group cross sections for full-core reactor simulation.
Lattice tower
A lattice tower is a tall, free-standing steel truss framework used chiefly to support overhead power lines and telecommunications antennas, its open lattice letting wind pass through.
Lattice-based cryptography
Lattice-based cryptography (lattice cryptography) is public-key cryptography whose security rests on hard lattice problems, making it resistant to quantum computer attacks; NIST standardized ML-KEM and ML-DSA in 2024.
Lattice-reduction-aided detection
Lattice-reduction-aided detection is a MIMO receiver technique that transforms the channel matrix into a nearly orthogonal basis, letting simple detectors approach maximum-likelihood performance at low complexity.
Laúca hydroelectric plant
The Laúca hydroelectric plant is a 2,070 MW hydropower complex on the Kwanza River in Angola, the country's largest, supplying about 40 percent of its electricity.
Lauda (airline)
Lauda, also known as Laudamotion or LaudaMotion, is a European low-cost airline founded by Niki Lauda in 2018, sold to Ryanair in 2018, and operating Airbus A320 aircraft for the Ryanair Group.
Lauda Air
Lauda Air was an Austrian airline founded in 1979 by Formula 1 champion Niki Lauda, absorbed by Austrian Airlines and retired as a brand in 2013.
Lauda Air Flight 004
Lauda Air Flight 004 was a Boeing 767 flying from Bangkok to Vienna that broke up in flight in 1991 after a thrust reverser deployed, killing all 223 aboard.
Lauderdale power station
Lauderdale power station is a Florida Power & Light generating site in Fort Lauderdale, Florida, hosting FPL's first plant since 1927 and the Dania Beach Clean Energy Center.
Laugo Alien
The Laugo Alien, also known as the Laugo Arms Alien, is a Czech semi-automatic competition pistol in 9mm, designed by Ján Lučanský and first shown in 2019.
Launch cost and price comparisons
Launch cost and price comparisons, also known as comparison of orbital launcher families, measure how much it costs to reach orbit, usually in dollars per kilogram to low Earth orbit.
Launch escape system
A launch escape system, or launch abort system, separates a crewed spacecraft from a failing launch vehicle on the pad or during ascent, returning the crew by parachute.
Launch pad
A launch pad, also called a launching pad, is a reinforced site where rockets are held, fueled, and fired at liftoff, with flame trenches and sound suppression.
Launch power optimization
Launch power optimization is the process of choosing the optical power each WDM channel launches into a fiber link, balancing OSNR gains against nonlinear interference that grows with the cube of power.
Launch vehicle
A launch vehicle, also known as a space launch vehicle, is a rocket-powered vehicle that carries a spacecraft from Earth into orbit or onto a trajectory beyond it.
Launch window
A launch window is the span of time during which a launch may take place while satisfying safety and mission constraints, at daily and planetary scales.
Launching gantry
A launching gantry, also called a launching girder or launcher gantry, is a self-propelled overhead steel truss that erects precast segmental bridges without ground cranes.
Launchpad (website)
Launchpad is a web-based software collaboration and hosting platform developed by Canonical, launched in 2004 to coordinate Ubuntu development and known for bug tracking, Git code hosting, and PPAs.
Laundry detergent
Laundry detergent, also known as washing powder, is a formulated cleaning product that removes dirt and stains from textiles, sold as powders, liquids, capsules, and sheets.
Laura Galante
Laura Galante is an American cyber threat intelligence and information-operations analyst who served from January 2022 to January 2025 as the Intelligence Community's Cyber Executive and CTIIC director.

Laurence D. Marks
Laurence D. Marks, born 1954, is a British-born materials scientist known for electron microscopy of nanoparticles and the Marks decahedron, a nanoparticle shape named after him.
Laurence Edward Scriven
Laurence Edward Scriven, known as Skip Scriven (1931–2007), was an American chemical engineer and Regents Professor at the University of Minnesota whose work on coating processes shaped modern coating science.
Laurence J. Adams
Laurence J. Adams (1921–2008) was an American aerospace engineer who managed the Titan rocket programs, helped defend Martin Marietta from a hostile takeover in 1982, and became its president.
Laurence Retman Young
Laurence Retman Young (1935–2021) was an American aerospace engineer and bioastronautics expert at MIT who studied the vestibular system, space motion sickness, and flight simulation.
Laurens van der Maaten
