Constrained reinforcement learning
Constrained reinforcement learning trains an agent to maximize reward under explicit limits on cost, risk, or resources, and is standard in safe reinforcement learning for robotics, driving, and healthcare.
Constrained-layer damping
Constrained-layer damping (CLD) is a passive vibration-control treatment in which a stiff constraining layer forces a bonded viscoelastic core into shear, dissipating vibrational energy as heat.
Constrained-random verification
Constrained-random verification (CRV) is a hardware design verification methodology in which a constraint solver generates random but legal test stimulus, and it underlies the standard UVM framework.
Constraint logic programming
Constraint logic programming (CLP) is a declarative programming scheme, defined by Joxan Jaffar and Jean-Louis Lassez in 1987, that combines logic programming with constraint solving over domains like integers and Booleans.
Constraint programming
Constraint programming is an approach where a problem is stated by constraints on decision variables, and a solver finds satisfying assignments by interleaving constraint propagation with systematic search.
Constraint propagation
Constraint propagation, also known as local consistency or filtering, is a family of polynomial-time algorithms for constraint satisfaction problems that remove values no solution can use.
Constraint satisfaction problem
A constraint satisfaction problem, also known as constraint solving, is an NP-complete computational problem of assigning values to variables under constraints, unifying satisfiability, graph coloring, and scheduling.
Constraint stabilization (multibody)
Constraint stabilization in multibody dynamics is a family of numerical techniques that keep simulated constrained systems on their constraint manifold, best known through Baumgarte's 1972 PD-control method.
Constrictor knot
The constrictor knot is a binding knot tied like a clove hitch with an extra tuck, gripping tightly but nearly impossible to untie once cinched.
Construcciones y Auxiliar de Ferrocarriles
Construcciones y Auxiliar de Ferrocarriles, also known as Grupo CAF, is a Spanish manufacturer of trains, trams, metros, and buses, headquartered in Beasain in the Basque Country.
Construct (game engine)
Construct is a browser-based 2D game engine developed by Scirra Ltd in London, letting users build games through a visual event system or optional JavaScript.
Constructability
Constructability is the optimal use of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives, a concept defined by the Construction Industry Institute in 1986.
Constructal design
Constructal design is an engineering method that applies the constructal law to generate flow geometries, such as tree-shaped networks, fins, and cavities, that ease heat, fluid, or mass flow.
Construction
Construction is the industry that builds and maintains buildings and civil engineering works such as roads, bridges, and tunnels, employing some 220 million people worldwide.
Construction and erection of cable-stayed bridges
Construction of cable-stayed bridges erects the deck by balanced cantilever, incremental launching, or temporary supports, with stay cables tensioned in stages and construction-stage analysis controlling geometry and cable forces.
Construction dewatering
Construction dewatering is the temporary lowering of the groundwater table around an excavation so below-ground work stays stable and dry, using methods like sump pumping, wellpoints, and deepwells.
Construction documents
Construction documents are the drawings and specifications that describe a building in enough detail for permit approval, and the third design phase in American Institute of Architects practice.
Construction engineering
Construction engineering, also called construction operations, is the branch of engineering that applies analysis and design to the construction process itself, from plans and specifications through facility completion.
Construction Industry Institute
The Construction Industry Institute (CII) is a consortium of owners, contractors, and academics researching capital project delivery, founded in 1983 at The University of Texas at Austin.
Construction management
Construction management is a professional practice controlling time, cost, scope, and quality on construction projects from start to finish, practiced as agency CM or construction management at risk.
Construction management at risk
Construction management at risk (CM at Risk) is a project delivery method in which an owner hires a construction manager during design to build the project at risk.
Construction of Brasília
The construction of Brasília built Brazil's new capital on the Planalto Central between 1957 and 1960, from plans by Lúcio Costa and buildings by Oscar Niemeyer.
Construction of model aircraft
Construction of model aircraft is the craft of building flying model airplanes from balsa, foam, and printed plastic, using commercial kits, drawings, or nearly finished ARF airframes.
Construction of the Overland Telegraph Line (1870–1872)
The construction of the Overland Telegraph Line (1870–1872) built a roughly 3,000-kilometer telegraph line across Australia from Port Augusta to Port Darwin, overseen by Charles Todd and completed on 22 August 1872.
Construction of the World Trade Center
The construction of the World Trade Center was the Port Authority's building of a seven-building complex in Lower Manhattan from 1966 to 1987, centered on the Twin Towers.
Construction Partners, Inc.
Construction Partners, Inc. is a Dothan, Alabama-based civil infrastructure company that builds, repairs, and maintains roadways across the Sunbelt, growing mainly by acquiring local paving and asphalt companies.
Construction worker
A construction worker is a person employed in building houses, roads, and other structures, doing site preparation, moving materials, and assisting tradesworkers such as electricians.
Consuegra Dam
Consuegra Dam (presa romana de Consuegra), Roman buttress dam on the Amarguillo river near Consuegra, Toledo, Spain; about 590-660 m long, 4.8 m high, 1st-4th century AD, longest Roman dam conserved in Hispania, declared Bien de Interés Cultural in 1992.
Consumer electronics
Consumer electronics, also called consumer technology, are electronic devices sold to end consumers for personal, household, or in-vehicle use, including smartphones, televisions, laptops, wearables, and gaming hardware.
Consumer Electronics Control
Consumer Electronics Control (CEC), commonly called HDMI-CEC, is a protocol on pin 13 of the HDMI connector that lets devices like TVs and players control one another.
