Dynamic window approach

The dynamic window approach (DWA) is a local obstacle-avoidance method for mobile robots, introduced by Fox, Burgard, and Thrun in 1997 and used as the default local planner in the ROS navigation stack.

Dynamic Yield

Dynamic Yield is a Tel Aviv-founded personalization software company whose Experience OS platform tailors digital content in real time, owned by Mastercard since 2022 after McDonald's bought it in 2019.

Dynamic-link library

A dynamic-link library (DLL), also called a dynamically linked library, is a shared library in Microsoft Windows containing functions and data used by applications and other DLLs.

Dynamical axion field

The dynamical axion field is a time- and space-dependent field in magnetic topological insulators, arising from magnetic fluctuations and coupling to electromagnetic fields like the hypothetical elementary axion.

Dynamical Casimir effect

The dynamical Casimir effect converts vacuum fluctuations of a quantum field into real photons through fast boundary changes, first observed in superconducting circuits in 2011.

Dynamical decoupling

Dynamical decoupling is a quantum control technique that applies timed pulse sequences to qubits to average away environmental noise, extending coherence time and improving gate fidelity.

Dynamical downscaling

Dynamical downscaling is a climate modeling technique in which a regional model driven at its boundaries by coarse global simulations produces higher-resolution regional climate projections.

Dynamical friction

Dynamical friction is the systematic deceleration a massive body, such as a satellite galaxy or star, experiences moving through lighter particles, derived by Subrahmanyan Chandrasekhar in 1943.

Dynamical gauge fields in cold atoms

Dynamical gauge fields in cold atoms are engineered quantum systems in which ultracold atoms in optical lattices simulate lattice gauge theories, reaching real-time dynamics beyond classical computation.

Dynamical lifetimes and stability of small Solar System bodies

The dynamical lifetime of a small Solar System body is how long it stays in a given orbital region before ejection, collision, or transfer to another class.

Dynamical mean-field theory

Dynamical mean-field theory (DMFT) is a non-perturbative computational method for strongly correlated electron systems, introduced by Antoine Georges and Gabriel Kotliar in 1992 to describe the Mott metal-insulator transition.

Dynamical quantum phase transition

A dynamical quantum phase transition is a sharp nonanalyticity in the real-time evolution of a quantum many-body system, typically after a quantum quench, introduced in 2013.

Dynamical Relaxation

Dynamical relaxation is the process by which a self-gravitating stellar system approaches statistical equilibrium, proceeding through two-body encounters or through violent relaxation driven by potential fluctuations.

Dynamical symmetry

Dynamical symmetry, also called hidden symmetry, is a symmetry of a quantum or classical system whose Hamiltonian is invariant under phase-space transformations beyond geometric symmetries.

Dynamical system

A dynamical system is a mathematical model of a process whose future is determined by its present state, through a state space and an evolution rule.

Dynamical triangulations

Dynamical triangulations (DT) is a lattice formulation of quantum gravity, arising in the 1980s, that replaces the path integral over spacetime geometries with a sum over equilateral simplicial triangulations.

Dynamical tunnelling

Dynamical tunnelling is quantum tunnelling between phase-space regions separated by classical dynamics rather than a static potential barrier, first described by Davis and Heller in 1981.

Dynamics (mechanics)

Dynamics, also known as classical dynamics, is the branch of mechanics studying how forces cause motion, in contrast with kinematics, and rests on Newton's laws of motion.

Dynamics (music)

Dynamics (music): the Italian-derived markings p (piano, soft) and f (forte, loud) and gradations like crescendo and diminuendo indicating relative loudness. Originating with Gabrieli's 1597 Sonata pian' e forte and matured with the fortepiano and Mannheim School, they are relative, not absolute, loudness instructions.

Dynamin

Dynamin (DNM1, DNM2, DNM3) is a 100-kDa large GTPase that forms helical polymers around endocytic bud necks and catalyzes GTP-dependent membrane fission in clathrin-mediated endocytosis; mutations cause Charcot-Marie-Tooth disease and centronuclear myopathy.

Dynamin, GTPase domain

Dynamin GTPase domain (G domain, InterPro IPR001401): the ~300-residue N-terminal GTP-binding/hydrolysis engine of dynamin superfamily proteins; dimerizes head-to-head with GDP·AlF4−, uses a catalytic cation instead of an arginine finger, and powers membrane fission.

DynaMIT

DynaMIT (Dynamic Network Assignment for the Management of Information to Travelers) is a simulation-based traffic estimation and prediction system developed at MIT, whose prototype appeared in 1998.

Dynamite

Dynamite is a class of high explosives in which nitroglycerin is absorbed into an inert filler to form a stable, moldable solid, patented by Alfred Nobel in 1867.

Dynamite (BTS song)

Dynamite, BTS's first all-English single, released August 21, 2020; disco-pop track by David Stewart and Jessica Agombar that debuted at No. 1 on the Billboard Hot 100, a first for a Korean act, and earned BTS its first Grammy nomination.

Dynamite Cop

Dynamite Cop (Dynamite Deka 2) is Sega's 1998 Model 2 arcade beat-'em-up, sequel to Die Hard Arcade, ported to Dreamcast in 1999; three commandos rescue the president's daughter from pirates on a hijacked cruise ship using improvised weapons.

Dynamite Kid

Dynamite Kid (Thomas Billington, 1958–2018), English pro wrestler, half of the British Bulldogs with cousin Davey Boy Smith; WWF tag champion at WrestleMania 2, famed for Tiger Mask matches in Japan.

Dynamite Kiss

Dynamite Kiss (키스는 괜히 해서!) is a 2025 SBS Wednesday-Thursday Korean romance comedy, 14 episodes, starring Jang Ki-yong and Ahn Eun-jin as a team leader and a single woman posing as a mother; it ended December 25, 2025 with its highest rating.

Dynamitin

Dynamitin (p50, DCTN2) is the 50-kDa dynactin subunit forming a shoulder tetramer that docks p150Glued to the Arp1 filament; its overexpression disassembles dynactin and inhibits dynein motility.

Dynamix

Dynamix, Inc. (not Autodesk's Dynamo Studio) was a Eugene, Oregon game developer founded in 1984 by Jeff Tunnell and Damon Slye, acquired by Sierra in 1990, known for Red Baron, The Incredible Machine, and Tribes, closed August 14, 2001.

Dynamo

A dynamo, or dynamo-electric machine, is a direct-current generator converting mechanical energy to DC by electromagnetic induction. Descended from Faraday's 1831 disk, it powered early lighting before alternators displaced it.
