Multistage detection

Multistage detection is a signal-detection method in digital communications in which the receiver estimates symbols in several successive passes, each stage using the previous one's decisions to cancel interference.

Multistage multiuser detector

A multistage multiuser detector is a CDMA receiver that removes multiple-access interference through successive stages, each canceling other users' signals; it was introduced by Varanasi and Aazhang in 1990.

Multistage rocket

A multistage rocket, or step rocket, is a launch vehicle built in two or more stages, each with its own engines and propellant, whose spent stages are dropped in flight.

Multistage sampling

Multistage sampling is a survey design that first selects clusters, then subsamples units within them, reducing framing costs; it underlies surveys such as the CPS and NHANES.

Multistage vector

A multistage vector (MSV) is a particle-in-particle drug delivery system, described by Mauro Ferrari's Houston group in 2011, in which a disc-shaped porous silicon microparticle carries nanoparticles holding the therapeutic payload.

Multistakeholder model of internet governance

The multistakeholder model of internet governance is a paradigm in which governments, the private sector, and civil society share decision-making, defined by the 2005 WSIS Tunis Agenda.

Multistate analysis

Multistate analysis is a statistical method for modeling how individuals move stochastically among a finite set of states over time, estimating transition rates and state probabilities.

Multistate model

A multistate model is a statistical model for continuous-time stochastic processes in which individuals move among a finite number of states, used in survival analysis and medical statistics.

Multistatic radar

Multistatic radar is a radar technique in which several spatially separated receivers, with one or more transmitters, observe a target to measure position, velocity, and wind or ocean-current fields.

Multisystem glycosylation enzyme defects

Multisystem glycosylation enzyme defects, or congenital disorders of glycosylation (CDG), are inherited enzyme defects in glycan synthesis and attachment, first described in 1980, with over 170 subtypes such as PMM2-CDG causing multi-organ disease.

Multisystem inflammatory syndrome in children and adults

MIS-C/A (MIS-C, MIS-A, PIMS-TS) is a rare post-infectious hyperinflammatory syndrome arising 2-6 weeks after often mild SARS-CoV-2 infection, mainly in children aged 5-11, with fever, cardiac involvement, and shock; incidence fell over 98% since 2021.

Multisystemic smooth muscle dysfunction syndrome

Multisystemic smooth muscle dysfunction syndrome (MSMDS, OMIM 613834) is an ultra-rare ACTA2-related genetic disorder causing congenital smooth muscle dysfunction, with fixed dilated pupils, patent ductus arteriosus, aortic and cerebrovascular disease, hypoperistalsis, and pulmonary hypertension.

Multisystemic therapy

Multisystemic therapy (MST) is an intensive, home-based psychotherapy for adolescents ages 12 to 17 with serious antisocial behavior, treating the family, school, and peers together.

Multitaper

The multitaper method is a nonparametric spectral estimation technique that reduces variance by averaging periodograms from orthogonal Slepian tapers, reported by D. J. Thomson in 1982.

Multitarn

Multitarn (German: Multitarndruck) is a six-color universal camouflage pattern of the German Bundeswehr, worn by special forces since about 2016 and replacing Flecktarn from 2026.

Multitask learning

Multitask learning (MTL) is a machine learning method that trains one model on several related tasks simultaneously, sharing a common representation that improves generalization on each task.

Multitask neural networks for QSAR

Multitask neural networks for QSAR predict the biological activities of chemical compounds against several targets at once, using one shared model instead of a separate QSAR model per endpoint.

Multitenancy

Multitenancy is a software architecture in which a single instance of an application serves multiple customer organizations, called tenants, lowering costs through shared infrastructure; it is how Software-as-a-Service is typically delivered.

Multithreading (computer architecture)

Multithreading in computer architecture is a set of hardware techniques that let one processor core hold and run several hardware threads at once, filling otherwise idle execution slots.

Multitier architecture

Multitier architecture, also called n-tier or three-tier architecture, is a software design pattern separating an application into presentation, application, and data tiers, popular since the 1990s.

Multitrack recording

Multitrack recording, also called multichannel recording, records separate audio signals on parallel tracks of one medium so each part can be modified, and mixed independently later.

Multiuser detection

Multiuser detection is a signal processing technique that recovers the data streams of multiple simultaneous users from a shared communication channel by treating their signals jointly.

Multivariable calculus

Multivariable calculus, also called multivariate calculus, is the branch of calculus extending differentiation and integration to functions of several variables and vector fields, culminating in Green's, Stokes', and Gauss' theorems.

Multivariate adaptive regression splines

Multivariate adaptive regression splines (MARS) is a nonparametric regression method introduced by Jerome H. Friedman in 1991, which fits a response with spline basis functions whose knots are chosen automatically from the data.

Multivariate analysis of variance

Multivariate analysis of variance (MANOVA) is a statistical procedure extending ANOVA to two or more correlated dependent variables, tested simultaneously using statistics such as Wilks' Lambda.

Multivariate calibration

Multivariate calibration is a chemometric method that builds a mathematical model relating many spectral signals to an analyte's concentration, so new samples can be quantified.

Multivariate curve resolution

Multivariate curve resolution (MCR) is a chemometric method that decomposes overlapping spectroscopy, chromatography, and imaging data into pure spectra and concentration profiles without prior separation.

Multivariate empirical mode decomposition

Multivariate empirical mode decomposition (MEMD) is a signal-processing method that decomposes multichannel, non-stationary data into scale-aligned intrinsic mode functions, introduced by Rehman and Mandic in 2009.

Multivariate ENSO Index

The Multivariate ENSO Index (MEI) is a bimonthly index monitoring the El Niño/Southern Oscillation by combining ocean and atmosphere variables, introduced by Klaus Wolter and Michael Timlin in 1993.
