Peacock Room
The Peacock Room is a dining room Whistler decorated in 1876–1877 for shipowner Frederick Leyland, a masterpiece of the Aesthetic movement now in Washington, DC.
Péage (autoroute toll system)
The péage is the toll system that finances France's motorway network: the State owns the roads and private concessionaires collect tolls at barriers or by electronic tolling.
Peak Aerospace Me 109R
Peak Aerospace Me 109R is a German replica warbird ultralight aircraft. Designed by Tassilo Bek, it is an 80 percent scale reproduction of the Messerschmitt Bf 109.
Peak current-mode control
Peak current-mode control is a widely used control method for DC-DC converters, invented in 1967, in which the sensed peak inductor current terminates each switch on-time.
Peak detection (signal processing)
Peak detection is the computational identification of local maxima in measured signals, estimating each peak's position, height, width, and significance; it is standard in processing mass spectra and chromatograms.
Peak detector
A peak detector is an electronic circuit that captures and stores the highest voltage reached by an input waveform, typically with a diode that charges a storage capacitor.
Peak Downs Coal Mine
Peak Downs Coal Mine is a large open-pit metallurgical coal mine in Queensland's Bowen Basin, about 30 km south of Moranbah, opened in 1972 and operated by BMA, a BHP and Mitsubishi joint venture.
Peak oil
Peak oil, or Hubbert peak oil, is the point when petroleum extraction reaches its maximum rate and production enters terminal decline, a concept from geophysicist M. King Hubbert.
Peak shaving
Peak shaving is a load management technique in power engineering that cuts a customer's maximum electricity demand, typically by discharging a battery, to lower demand charges and relieve grid stress.
Peak signal-to-noise ratio
Peak signal-to-noise ratio (PSNR) is a decibel metric that quantifies how faithfully a compressed or reconstructed image matches the original, widely used in image and video compression.
Peak-to-average power ratio reduction
Peak-to-average power ratio reduction is the set of signal-processing techniques that lower peak power in OFDM waveforms, chiefly through clipping, tone reservation, and scrambling methods.
Peano-HASEL actuator
A Peano-HASEL actuator is a soft artificial muscle made of a liquid-filled plastic pouch that contracts under high voltage, introduced at the University of Colorado Boulder in 2018.
PEAQ
PEAQ (Perceptual Evaluation of Audio Quality), standardized as ITU-R BS.1387 in 1998, objectively measures perceived audio quality by comparing a processed signal against the original.
Pearl GTL
Pearl GTL is the world's largest gas-to-liquids plant, at Ras Laffan Industrial City in Qatar, developed by Shell and QatarEnergy and producing 140,000 barrels per day.
Pearl Harbor Memorial Bridge (Connecticut)
The Pearl Harbor Memorial Bridge, informally the Q Bridge, carries Interstate 95 over New Haven Harbor in Connecticut and is the first extradosed bridge in the United States.
Pearl North Field Gas Pipelines
The Pearl North Field gas pipelines are two subsea pipelines carrying sour gas from Qatar's North Field to the Pearl GTL plant at Ras Laffan, operating since 2011.
Peaucellier–Lipkin linkage
The Peaucellier–Lipkin linkage, also called the Peaucellier inversor, is an eight-bar mechanism that converts rotary motion into exact straight-line motion, invented in 1864 as the first planar linkage to trace a perfect line.
PEB (building energy performance requirement)
PEB, in Dutch EPB (Energy Performance and Indoor Climate), is the family of building energy performance requirements imposed in Belgium's three regions on new construction and renovation.
Pebble (watch)
Pebble is a line of smartwatches developed by Pebble Technology Corporation; its 2012 Kickstarter e-paper watch set crowdfunding records before Fitbit bought the company in 2016.
Pebble Mill Studios
Pebble Mill Studios, also known as BBC Pebble Mill, was the BBC's television, radio, and news complex in Edgbaston, Birmingham, opened in 1971 and demolished in 2005.
Pebble-bed modular reactor
The Pebble-bed modular reactor was a South African high-temperature gas-cooled reactor design developed by Eskom's PBMR company, funded from the mid-1990s until 2010, and revived in 2025.
Pebble-bed reactor
A pebble-bed reactor is a high-temperature gas-cooled nuclear reactor in which fuel pebbles circulate through the core while helium carries heat away, allowing refueling without shutdown.
Pecém FSRU
The Pecém FSRU was Brazil's first LNG import terminal, a floating regasification unit at the Port of Pecém, Ceará, operated by Petrobras from 2009 to 2023.
Pechora GRES power station
Pechora GRES (Печорская ГРЭС) is a 1,060 MW thermal power station near Pechora in the Komi Republic, Russia, the republic's largest, supplying about 40 percent of its electricity.
Peckforton Castle
Peckforton Castle is a Grade I listed Victorian country house built as a medieval castle near Tarporley in Cheshire, England, and now operating as a hotel.
