Resonant magnetic perturbation
A resonant magnetic perturbation (RMP) is a small non-axisymmetric magnetic field applied in a tokamak by external or in-vessel coils, used chiefly to suppress edge-localized modes.
Resonant orbit
A resonant orbit is a spacecraft orbit whose period is commensurate with a repeating cycle, usually Earth's rotation, so it passes over the same ground points on schedule.
Resonant photoemission
Resonant photoemission is a photoelectron spectroscopy variant in which the photon energy is tuned to a core-level absorption threshold, enhancing valence-band emission through an interfering indirect decay channel and making the technique element selective.
Resonant transformer
A resonant transformer is a high-voltage test transformer operated in a resonant circuit, producing large test voltages from a small power source for testing cables and switchgear.
Resonant tunneling
Resonant tunneling is a quantum-mechanical effect in which electron transmission through a double-barrier structure rises sharply when the electron energy matches a quantized energy level of the well between the barriers.
Resonant two-photon ionization
Resonant two-photon ionization is a laser photoionization process in which an atom absorbs two photons, one resonant with an excited state, removing an electron with near-unity probability.
Resonant ultrasound spectroscopy
Resonant ultrasound spectroscopy (RUS) measures the natural vibrational frequencies of a small solid sample and computes all its elastic constants, up to 21, in one experiment.
Resonant-cavity light-emitting diode
A resonant-cavity light-emitting diode (RCLED), also called a micro-cavity LED, is an LED whose active region sits inside an optical cavity, demonstrated in 1992 at Bell Laboratories.
Resonant-tunneling diode
A resonant-tunneling diode (RTD) is a semiconductor device in which electrons tunnel through a double-barrier quantum well, producing negative differential resistance and enabling oscillators that reach terahertz frequencies at room temperature.
Resonator
A resonator is a physical system that vibrates strongly at its resonance frequencies; in acoustics, usually an air cavity whose shape and size set those frequencies.
Resonator guitar
Resonator guitar, also called resophonic guitar or Dobro: acoustic guitar with spun aluminum cones replacing the soundboard, invented by John Dopyera in 1920s Los Angeles; tricone, biscuit, and spider-bridge designs used in blues and bluegrass.
Resorcinol
Resorcinol, also known as benzene-1,3-diol, is a white crystalline aromatic compound with formula C6H4(OH)2, used chiefly in rubber and wood adhesives and in dyes, hair colorants, and topical acne and psoriasis treatments.
Resort
Resort: self-contained lodging offering recreation, dining, and entertainment on site. Types include beach, mountain, spa, golf, island, and all-inclusive resorts; origins trace to British spa and seaside towns like Scarborough.
Resort (TV series)
Resort (ரிசார்ட்) is a 2026 Indian Tamil-language comedy-drama series on JioHotstar, created by and starring YouTuber Vijay Kumar Rajendran, running 100 episodes in its first season.
Resort to Love
Resort to Love is a 2021 Netflix romantic comedy directed by Steven K. Tsuchida, starring Christina Milian, Jay Pharoah, Sinqua Walls, and Christiani Pitts, shot entirely in Mauritius for $11 million and released July 29, 2021.
Resorte
Resorte is a rap-metal and nu-metal band from Mexico City, founded in 1995, whose debut República de Ciegos is called the pioneering album of Mexican nu metal.
Resorts World Las Vegas
Resorts World Las Vegas, a $4.3 billion Genting Berhad integrated hotel-casino on the former Stardust site, opened June 24, 2021 as the first ground-up Strip resort in over a decade, with 3,506 rooms across three Hilton brands and a $10.5 million 2025 AML fine.
Resorts World New York City
Resorts World New York City (RWNYC) is Genting's casino at Aqueduct Racetrack in Jamaica, Queens; opened October 2011 as a 415,000 sq ft VLT facility, NYC's only casino, adding live table games in 2026 and proposing a $5.5 billion integrated resort.
Resorts World Sentosa Casino
Resorts World Sentosa Casino, run by Resorts World at Sentosa Pte. Ltd. (Genting Singapore), is one of Singapore's two legal casinos, opened February 2010 on Sentosa Island, capped at 15,000 square metres of gaming area, licence renewed to February 2027.
Resource
A resource is a naturally occurring asset such as a fish stock, forest, aquifer, or mineral deposit; resource economics studies how its allocation is organized, priced, and governed.
Resource acquisition is initialization
Resource acquisition is initialization, also known as scope-bound resource management, is a C++ technique where an object's constructor acquires a resource and its destructor releases it automatically.
Resource allocation
Resource allocation in microeconomics is how a society distributes scarce resources among competing uses, deciding what to produce, how to produce it, and for whom, through markets, planning, or custom.
Resource Capital Funds
Resource Capital Funds is a Denver, Colorado private equity firm specializing in mining, metals, and critical minerals, founded in 1998 by James McClements and Henderson Tuten.
Resource conservation
Resource conservation is the protection and sustainable use of natural resources, reducing consumption and reusing recovered materials. It spans renewable and nonrenewable resources, the Pinchot-era conservation movement, soil and agricultural programs, and evaluated policies such as protected areas.
Resource curse
Resource curse, or paradox of plenty: the finding that oil, gas, and mineral-rich countries often show slower growth, weaker democracy, and worse development outcomes; evidence since Sachs and Warner (1995) is mixed and conditional on institutions.
Resource depletion
Resource depletion, also called natural resource depletion, is the decrease in a natural resource stock caused by extraction faster than regeneration, covering oil, minerals, and groundwater.
Resource Description Framework
Resource Description Framework (RDF) is a W3C standard data model that represents information as subject–predicate–object triples in directed graphs, underpinning the Semantic Web and Linked Data and queried with SPARQL.
Resource efficiency
Resource efficiency is the practice of creating more economic value with less input of natural resources, materials, energy, and water, decoupling growth from extraction and environmental degradation.
Resource inequalities (quantum information theory)
Resource inequalities are bookkeeping statements in quantum information theory that protocols convert among classical bits, qubit channels, and shared entanglement, with teleportation and superdense coding as unit examples.
Resource management
Resource management is the practice of planning, scheduling, allocating, and optimizing the people, equipment, and money an organization needs to deliver its work, distinct from project management, which requests resources for a single project.
