Resalat oil field
Resalat is an offshore oil field in the Persian Gulf, about 90 kilometers south of Lavan Island, Iran, discovered in 1967 and operated by IOOC.
Rescue 1122
Rescue 1122 is the emergency number and name of Pakistan's government-run pre-hospital emergency services, begun in Punjab in 2004 and providing ambulance, firefighting, and water rescue.
Research and development
Research and development (R&D) is systematic, uncertain work to increase knowledge and devise new applications, defined by the OECD's Frascati Manual and worth about $3.8 trillion globally in 2024.
Research stations in Antarctica
Research stations in Antarctica are permanently or seasonally staffed scientific facilities built by national programs; as of the 2020s, 30 nations manage more than 70 stations, descended largely from the 1957–58 International Geophysical Year.
Research Triangle Park
Research Triangle Park (RTP) is a 7,000-acre research park in North Carolina between Raleigh, Durham, and Chapel Hill, founded in 1959 and the largest in the United States.
ResearchGate
ResearchGate is a Berlin-based academic social networking site where researchers share publications, ask and answer research questions, and track metrics, founded in 2008 by physicians Ijad Madisch and Sören Hofmayer.
Réseau de Transport d'Électricité
Réseau de Transport d'Électricité (RTE) is the French transmission system operator that owns and runs the high-voltage electricity grid in mainland France, created in 2000.
Réseau Express Régional
The Réseau Express Régional (RER), or Regional Express Network, is Paris's hybrid express rail system, whose five lines run through the capital underground rather than terminating there.
Reservation against Cancellation
Reservation against Cancellation (RAC) is a ticket status used by Indian Railways when confirmed berths are exhausted, guaranteeing a seat that two passengers share until a cancellation frees a berth.
Reservation station
A reservation station is a buffer in an out-of-order processor that holds an instruction and its operands until they are ready, introduced in the IBM System/360 Model 91 in 1967.
Reservation-based intersection control
Reservation-based intersection control is a traffic-management method in which vehicles reserve exclusive space-time at an intersection from a manager, introduced by Dresner and Stone in 2004.
Reserve replacement ratio
The reserve replacement ratio (RRR) is an upstream oil and gas measure dividing net proved reserves added by production; above 100% means the reserve base grew.
Reservoir
A reservoir, also called a storage reservoir, is a lake, often man-made behind a dam, storing water for public supply, irrigation, flood control, and power.
Reservoir characterization
Reservoir characterization is the process of integrating geological, geophysical, petrophysical, and reservoir engineering data to describe petroleum reservoir properties, particularly at locations between wells, using well logs, cores, and seismic data.
Reservoir computing
Reservoir computing, also known as physical reservoir computing, is a machine learning framework where a fixed reservoir processes temporal data and only a linear readout is trained.
Reservoir computing forecasting of chaotic systems
Reservoir computing forecasting of chaotic systems uses reservoir computing, a machine learning framework with a fixed recurrent network and trained readout, to predict chaotic dynamics.
Reservoir engineering
Reservoir engineering is the branch of petroleum engineering that applies engineering principles to oil and gas reservoirs, estimating reserves and predicting fluid flow and recovery.
Reservoir sampling
Reservoir sampling is a family of algorithms that draw a uniform random sample of k items from a stream of unknown length in a single pass.
Reservoir-induced seismicity
Reservoir-induced seismicity, also called reservoir-triggered seismicity, is earthquake activity caused by filling artificial reservoirs; the largest case was the magnitude 6.5 Koyna earthquake in India in 1967.
Reservoirs Act 1975
The Reservoirs Act 1975 is a UK law regulating the safety of large raised reservoirs in England and Wales through registration, inspection, and supervision by qualified civil engineers.
Reservoirs in Germany
Reservoirs in Germany are impounded by 530 operating dams, 266 of them large dams, led by Saxony with 190 and used mainly for flood control, recreation, and energy.
Reservoirs in the Czech Republic
The reservoirs of the Czech Republic are artificial lakes impounded by dams across the country's rivers, including 115 large reservoirs; the largest, Orlík, holds 720 million m³.
Reservoirs of East Asia
The reservoirs of East Asia are dominated by China's roughly 98,000 reservoirs, the world's largest system with about 980 km³ of storage, led by Three Gorges.
Reservoirs of New Zealand
The reservoirs of New Zealand are impounded water bodies built for hydroelectricity storage, measured in gigawatt-hours rather than volume, with almost all controllable storage in the South Island.
Reservoirs of Southeast Asia
Reservoirs of Southeast Asia covers impounding reservoirs for water supply and storage across the region, where 186 large reservoirs hold about 175 cubic kilometers, led by Thailand's Srinagarind and Bhumibol.
Reservoirs of Spain
Reservoirs of Spain, called embalses in Spanish, are artificial lakes impounded by dams on Spanish rivers; Spain leads the EU with more than 1,200 large dams holding about 56,000 hm³.
Reservoirs of the Alps
Reservoirs of the Alps are high-altitude impounding basins that store meltwater in summer and release it through turbines to generate hydroelectricity during the winter peak in demand.
Reservoirs of West and Central Asia
The reservoirs of West and Central Asia are artificial lakes behind dams storing seasonal river flow for irrigation, water supply, and hydropower, mostly built since the 1950s.
Reshadat oil field
Reshadat is an offshore oil field in the Persian Gulf, about 100 km southwest of Iran's Lavan Island. It was known as Rostam before the 1979 revolution.
Reshef Tenne
Reshef Tenne is an Israeli materials scientist and professor at the Weizmann Institute of Science, known for the 1992 discovery of inorganic fullerene-like nanoparticles and nanotubes of tungsten disulfide.
