Limit analysis
Limit analysis is a plasticity method that computes bounds on the collapse load of structures and soil masses using lower-bound and upper-bound theorems, without incremental load stepping.
Limit cycle walking
Limit cycle walking is a bipedal robot locomotion paradigm in which a nominally periodic stepping gait is stable as a whole, not at every instant.
Limit equilibrium method
The limit equilibrium method is a geotechnical analysis technique that computes a factor of safety for a potential slope failure along an assumed slip surface.
Limit state design
Limit state design is a structural engineering method that verifies safety and serviceability by checking defined limit states with partial safety factors on loads and material strengths.
Limited feedback beamforming
Limited feedback beamforming is a wireless technique where a receiver selects the best beamforming vector from a shared codebook and returns its index, a few bits, to the transmitter.
Limited-memory BFGS
Limited-memory BFGS, or L-BFGS, is a quasi-Newton optimization algorithm introduced by Jorge Nocedal in 1980 that minimizes large differentiable functions without storing the full inverse Hessian.
Limited-slip differential
A limited-slip differential (LSD), also called posi-traction, is a car differential that sends more torque to the wheel with better traction, helping vehicles escape mud, ice, and snow.
Limiting oxygen index
The limiting oxygen index (LOI) is the minimum percentage of oxygen in an oxygen–nitrogen mixture that sustains a material's burning, introduced by Fenimore and Martin in 1966.
Limousine
A limousine is a luxury chauffeur-driven car with an enclosed passenger compartment separated from the driver, formally defined in 1916 and best known today in the stretched form.
Limpet mine
A limpet mine is an explosive naval mine attached directly to a ship's hull by a diver, usually with magnets, and detonated on a time delay.
