Advanced Placement
Advanced Placement (AP) is a College Board program of college-level high school courses and May exams scored 1-5, with credit often granted for 3+; founded via the Kenyon Plan, now largely digital on Bluebook.
Advanced potential
An advanced potential is a solution of the electromagnetic wave equation whose value is set by sources at a later time, a wave propagating backward in time.
Advanced Power Management
Advanced Power Management (APM) is a BIOS-level power management specification for x86 personal computers, published by Intel and Microsoft in 1992 and superseded by ACPI.
Advanced Precision Kill Weapon System
The Advanced Precision Kill Weapon System (APKWS) is a BAE Systems laser-guidance kit that converts unguided 2.75-inch rockets like the Hydra 70 into precision-guided munitions for U.S. forces.
Advanced process control
Advanced process control (APC) is a layer of model-based, multivariable control techniques built above a plant's regulatory PID loops, most prominently model predictive control, to keep outputs near targets.
Advanced product quality planning
Advanced product quality planning (APQP) is a structured, five-phase framework used mainly in the automotive industry to plan and validate products before mass production, catching problems early.
Advanced Radiographic Capability
The Advanced Radiographic Capability (ARC) is a petawatt-class short-pulse laser at the National Ignition Facility in California, commissioned in 2015 to x-ray imploding fusion targets.
Advanced Rail Energy Storage
Advanced Rail Energy Storage, or ARES, is a gravity-based grid storage technology in which surplus electricity pushes rail cars uphill and their descent regenerates power for the grid.
Advanced Reactors Demonstration Program
The Advanced Reactor Demonstration Program (ARDP) is a U.S. Department of Energy program launched in May 2020 to fund advanced nuclear reactors through cost-shared partnerships with private industry.
Advanced Reconnaissance Vehicle
The Advanced Reconnaissance Vehicle (ARV) is a planned US Marine Corps combat vehicle family intended to replace the Light Armored Vehicle, with six variants and prototypes from Textron and General Dynamics.
Advanced reduction processes
Advanced reduction processes are water-treatment technologies that destroy persistent contaminants such as PFAS by generating short-lived, highly reducing hydrated electrons, usually with UV light and sulfite or iodide.
Advanced Research WRF model
The Advanced Research WRF model (ARW) is the research dynamical core of the open-source Weather Research and Forecasting system, used to simulate weather from cloud scales to the globe.
Advanced Robotics (journal)
Advanced Robotics is a peer-reviewed robotics journal published by Taylor & Francis on behalf of the Robotics Society of Japan, first issued in 1986 with 24 issues yearly.
Advanced sleep-wake phase disorder
Advanced sleep-wake phase disorder (ASWPD), formerly advanced sleep phase disorder, is a circadian rhythm sleep-wake disorder with persistently early sleep onset and morning awakening, often familial, treated with evening light therapy.
Advanced Squad Leader
Advanced Squad Leader (ASL) is MMP's squad-level WWII tactical board wargame system, successor to 1977's Squad Leader, with a 300+ page rulebook, 7,000+ scenarios, IGO-UGO turns, VASL online play, and Starter Kits for entry.
Advanced Stirling radioisotope generator
The Advanced Stirling Radioisotope Generator (ASRG) was a NASA and Department of Energy project converting plutonium-238 heat into about 130 watts of electricity, canceled in 2013.
Advanced Surface Movement Guidance and Control System
An Advanced Surface Movement Guidance and Control System (A-SMGCS) is an airport ground system providing surveillance, alerting, routing, and guidance for aircraft and vehicles, in all weather.
Advanced Tactical Fighter
The Advanced Tactical Fighter (ATF) was a 1980s US Air Force program to build a stealthy supersonic-cruising air-superiority fighter, won by the YF-22, which became the F-22 Raptor.
Advanced Test Reactor
The Advanced Test Reactor (ATR) is a 250-megawatt pressurized water test reactor at Idaho National Laboratory, operating since 1967, that irradiates nuclear fuels and materials for the U.S. Navy and other users.
Advanced tokamak
An advanced tokamak (AT) is a tokamak operating mode in which plasma current and pressure profiles are actively tailored, enabling continuous steady-state fusion operation at higher performance than conventional pulsed operation.
Advanced Toroidal Facility
The Advanced Toroidal Facility (ATF) was an experimental stellarator, a torsatron, at Oak Ridge National Laboratory and the world's largest stellarator when it began operating in 1988.
Advanced traffic management system
An advanced traffic management system (ATMS) is an intelligent transportation system using sensors, software, and a traffic management center to monitor roads and control traffic in real time.
Advanced trauma life support
Advanced Trauma Life Support (ATLS) is the American College of Surgeons' standardized trauma training course, developed in 1978 by James K. Styner, using the ABCDE (now xABCDE) primary survey, taught to over 50,000 learners yearly in 80+ countries.
Advanced Vector Extensions
Advanced Vector Extensions (AVX) is a family of SIMD extensions to the x86 instruction set architecture, widening vector registers from 128 bits to 256 and then 512 bits.
Advanced Video Coding
Advanced Video Coding, also known as H.264 or MPEG-4 Part 10, is a video compression standard approved in 2003 and still the most widely deployed codec on the internet.
Advanced Virgo
Advanced Virgo is the second-generation, kilometer-scale gravitational-wave laser interferometer at Cascina near Pisa, Italy, operated by the Virgo Collaboration; with LIGO it localized sources like GW170814 to 60 deg².
