Wauwermans Islands
Wauwermans Islands: northernmost island group of the Wilhelm Archipelago off the Antarctic Peninsula, charted by the Belgian Antarctic Expedition in 1898 and named after Lieut. Gen. H. Wauwermans of Antwerp; islands named for Canterbury Tales characters.
WAV
WAV, or Waveform Audio File Format, is a Microsoft and IBM audio file format introduced in 1991 on the RIFF container, typically holding uncompressed PCM audio and used for archival storage.
Wav2Vec 2.0
Wav2Vec 2.0 is a self-supervised speech representation model from Facebook AI Research, released in October 2020, which learns from raw audio without transcripts and reaches strong accuracy with only 10 minutes of labeled speech.
Wave
A wave is a disturbance that propagates through space and time, transferring energy without transporting the medium's material, appearing as ripples on water, sound in air, light, and seismic shaking.
Wave (audience)
The wave (audience), also called the Mexican wave or La Ola, is a stadium phenomenon in which spectators stand and sit in succession, sending a wave around the stands.
Wave breaking (plasma physics)
Wave breaking in plasma physics is the destruction of a large-amplitude plasma wave when its electrons overtake the wave crest, setting the maximum electric field the wave can sustain.
Wave diffraction
Wave diffraction is the lateral transfer of wave energy along a wave crest into the sheltered region behind an obstacle such as a breakwater or island.
Wave drag
Wave drag is aerodynamic drag caused by shock waves around a body moving at transonic or supersonic speeds, rising to a peak near Mach 1.
Wave Dragon
Wave Dragon is a Danish floating, offshore wave energy converter of the overtopping type, whose parabolic reflector arms concentrate waves into a reservoir above sea level.
Wave equation
The wave equation, or linear wave equation, is the partial differential equation describing a disturbance propagating at constant speed through a medium, governing sound, water waves, and light.
Wave equation analysis of pile driving
Wave equation analysis of pile driving is a computer-based method modeling stress-wave propagation through hammer, cushions, pile, and soil to predict driving stresses, blow counts, and pile bearing capacity.
Wave Equity Partners
Wave Equity Partners is a Boston-based growth-equity venture firm, founded in 2008 by Mark Robinson, Praveen Sahay, and Haskell Crocker, that invests in clean energy, food, water, air, and recycling technologies.
Wave function
A wave function is a complex-valued function representing the quantum state of a physical system; its squared magnitude gives the probability density for measurement outcomes.
Wave function collapse
Wave function collapse, also called state reduction or the projection postulate, is the rule by which measurement makes a quantum superposition randomly jump to a definite state.
Wave Glider
The Wave Glider is an autonomous, uncrewed surface vehicle made by Liquid Robotics, a Boeing subsidiary, that converts ocean wave energy into thrust and runs up to 12 months at sea.
Wave heating and current drive
Wave heating and current drive is the absorption of radio-frequency and microwave waves by magnetized plasma, heating fusion plasmas and driving sustained current in tokamaks.
Wave Hill walk-off
The Wave Hill walk-off, also called the Gurindji strike, began in August 1966 when about 200 Aboriginal workers led by Vincent Lingiari left Wave Hill Station, Northern Territory, over pay and conditions.
Wave Hub
Wave Hub is a grid-connected offshore testing facility for wave energy devices, installed in 2010 about 16 km off Cornwall, England, and sold in 2021 to the Swedish developer Hexicon.
Wave impedance
Wave impedance, also known as electromagnetic impedance, is the ratio of electric field strength to magnetic field strength in an electromagnetic wave, expressed in ohms.
Wave intensity analysis
Wave intensity analysis is a time-domain hemodynamic method, introduced by Parker and Jones in 1990, that quantifies forward and backward arterial waves from simultaneous pressure and velocity measurements.
Wave interference
Wave interference, also called interference of waves, is the phenomenon in which two or more waves occupying the same region combine by adding their disturbances.
Wave load analysis
Wave load analysis determines the forces ocean waves exert on fixed and floating marine structures, including jackets, platforms, breakwaters, ship hulls, and offshore wind foundations; waves usually dominate design.
Wave Makers (人选之人-造浪者)
Wave Makers (人選之人—造浪者) is a 2023 eight-episode Taiwanese political workplace drama on Netflix by DaMou Entertainment and PTS, following fictional campaign staffers; it won four Golden Bell Awards and helped spark Taiwan's #MeToo movement.
Wave maps
A wave map is a map from Minkowski space into a Riemannian manifold that is a critical point of a natural action, the hyperbolic analog of a harmonic map.
Wave mechanics
Wave mechanics is the formulation of quantum mechanics that describes a system by a wave function obeying the Schrödinger equation, created by Erwin Schrödinger in 1926.
Wave model
Wave model (Wellentheorie), proposed by Johannes Schmidt in 1872 after Hugo Schuchardt: historical-linguistics model in which innovations spread as overlapping waves across dialect continua, producing intersecting isoglosses instead of a branching family tree.
Wave packet
A wave packet, also called a wave group or wave train, is a localized wave built by superposing plane waves, used in quantum mechanics to represent a particle.
Wave picking
Wave picking is a warehouse order-picking method in which groups of orders are released together in scheduled waves built around carrier cutoffs, priority, and delivery dates.
Wave pool
Wave pool: artificial pool with machine-generated waves, also called surf park or wave lagoon. Origins with Ludwig II of Bavaria (1845-1886); Big Surf, Tempe (1969) first surfable; Slater hydrofoil and Surf Abu Dhabi hold the height record.
Wave power
Wave power, also called wave energy, is the capture of energy in ocean surface waves and its conversion into electricity, most often by wave energy converters that turn wave motion into electrical energy.
