Dynamic frequency selection

Dynamic frequency selection (DFS) is a spectrum-sharing mechanism requiring Wi-Fi devices in the 5 GHz band to detect radar signals and vacate the channel within 10 seconds.

Dynamic functional connectivity

Dynamic functional connectivity (dFC) is a neuroimaging analysis method that measures how statistical dependence between brain regions' activity changes over the course of an fMRI scan.

Dynamic gain equalizer

A dynamic gain equalizer (DGE), also called a dynamic gain-flattening filter, is an optical component that keeps all DWDM wavelength channels at comparable power levels.

Dynamic global vegetation model

A dynamic global vegetation model (DGVM) is a process-based ecosystem model simulating vegetation dynamics and carbon, water, and energy fluxes between land and atmosphere, used in climate modeling.

Dynamic graph learning

Dynamic graph learning, also known as dynamic graph representation learning, is a machine learning approach that learns representations of graphs whose nodes and edges change over time.

Dynamic heterogeneity is the spatially nonuniform relaxation of glass-forming liquids near the glass transition: particles rearrange in mobile clusters while surrounding regions stay frozen, with dynamics varying by orders of magnitude over a few nanometers.

Dynamic Host Configuration Protocol

The Dynamic Host Configuration Protocol (DHCP) is a client-server network protocol that automatically assigns IP addresses and settings like subnet mask, gateway, and DNS servers to devices, defined for IPv4 by RFC 2131 in 1997.

Dynamic hydrogels

Dynamic hydrogels are highly hydrated polymer networks whose crosslinks reversibly break and reform through noncovalent interactions or dynamic covalent bonds, giving self-healing, stress relaxation, and shear-thinning properties suited to drug delivery, tissue engineering, and bioprinting.

Dynamic image analysis

Dynamic image analysis (DIA) is a particle characterization technique in which particles moving through a stream are imaged by a high-speed camera and individually sized and shape-characterized.

Dynamic kinetic resolution

Dynamic kinetic resolution (DKR) is an asymmetric synthesis strategy that combines kinetic resolution with continuous racemization of the slower-reacting enantiomer, raising the theoretical yield from 50 to 100 percent.

Dynamic light scattering

Dynamic light scattering, also called photon correlation spectroscopy or quasi-elastic light scattering, measures the size of particles, droplets, or bubbles dispersed in liquids by analyzing laser light fluctuations.

Dynamic line rating

Dynamic line rating (DLR) is a power-systems technique that sets an overhead transmission line's capacity from real-time weather, typically raising usable capacity 10 to 30% over static ratings.

Dynamic load management

Dynamic load management, also called dynamic load balancing, controls electric vehicle charging power in real time from live site measurements, keeping total demand within electrical limits while using available capacity fully.

Dynamic logic (computer science)

Dynamic logic is a family of modal logics whose modalities are indexed by programs, generalizing box and diamond; its propositional variant PDL was introduced by Fischer and Ladner in 1979.

Dynamic Maze

Dynamic Maze (다이나믹 메이즈) is a South Korean indoor mission-maze attraction chain by Creative Tong, with branches in Seoul Insadong, Sokcho, Jeju, and Busan; visitors clear 15-16 puzzle and obstacle stages in about 30-40 minutes.

Dynamic mechanical analysis

Dynamic mechanical analysis (DMA), also called dynamic mechanical thermal analysis (DMTA), applies oscillatory stress or strain to measure a material's viscoelastic properties across temperature or frequency.

Dynamic memory allocation

Dynamic memory allocation is a programming technique that reserves and releases memory for data structures while a program runs, rather than fixing their sizes at compile time.

Dynamic mode decomposition

Dynamic mode decomposition (DMD) is a data-driven technique, proposed by Peter Schmid in 2008, that decomposes snapshot sequences into modes, each with one frequency and growth rate.

Dynamic modulus (asphalt mixtures)

The dynamic modulus of an asphalt mixture, written |E|, measures asphalt concrete stiffness across temperatures and loading rates, and is a required stiffness input to the MEPDG.

Dynamic movement primitive

A dynamic movement primitive (DMP) is a mathematical formulation in robotics that represents movements as stable nonlinear dynamical systems, with trajectory shapes learned from demonstrations.

Dynamic multi-objective optimization

Dynamic multi-objective optimization (DMO) is the study of methods that track and update Pareto-optimal trade-off solutions while a problem's objectives or constraints change over time, using evolutionary algorithms.

Dynamic network analysis

Dynamic network analysis (DNA) is a family of methods in social network analysis for modeling networks whose nodes, ties, and attributes change over time rather than as static snapshots.

Dynamic nuclear polarization

Dynamic nuclear polarization (DNP) is a magnetic resonance technique that transfers the large spin polarization of unpaired electrons to atomic nuclei, amplifying NMR signals by orders of magnitude.

Dynamic panel model

The dynamic panel data model, or dynamic panel data model, is a panel regression with a lagged dependent variable, estimated consistently by Arellano–Bond difference GMM or system GMM.

Dynamic PET

Dynamic PET is a nuclear medicine imaging method that records PET data continuously after tracer injection, fitting tracer kinetics to quantify physiological rate constants rather than a single static image.

Dynamic plasticity

Dynamic plasticity is the study of permanent deformation of solids at high strain rates and under shock loading, studied with tests like the split Hopkinson pressure bar.

Dynamic point selection

Dynamic point selection (DPS) is a downlink coordinated multi-point (CoMP) transmission scheme in cellular networks in which a user's data is sent from one cooperating transmission point, chosen dynamically.

Dynamic positioning

Dynamic positioning is a marine control method that automatically holds a vessel's position and heading using its own thrusters, without anchors, typically within 1 to 2 meters.

Dynamic posturography

Dynamic posturography is a clinical assessment that measures postural sway and balance reactions while visual and support-surface cues are perturbed, quantifying the sensory and motor contributions to balance.
