MPc

Mpc is an acronym that can refer to several terms in science and technology. The meaning depends on the field and context, with common uses in astronomy, cryptography, control theory, and music technology.

Megaparsec

A megaparsec (Mpc) is a unit of length used in astronomy to describe large-scale distances. One parsec equals about 3.26 light-years, so a megaparsec is about one million parsecs, or roughly 3.26 million light-years. In meters, 1 Mpc is about 3.09 × 10^22. Astronomers use Mpc to express distances to galaxies, clusters, and cosmic structures such as filaments and voids.

Multi-Party Computation

Multi-Party Computation, typically abbreviated MPC, is a cryptographic technique that enables several parties to jointly compute a function over their inputs while keeping those inputs private. It relies on secret sharing, secure multiparty protocols, and cryptographic assumptions. Applications include privacy-preserving data analysis, private set intersection, auctions, and threshold cryptography. Efficiency and communication costs remain active research areas.

Model Predictive Control

Model Predictive Control, also abbreviated MPC, is a method in control engineering for regulating dynamic systems. It uses a model to forecast future behavior and solves an optimization problem at each time step to minimize a cost function subject to constraints. The first control move is implemented, and the horizon shifts forward. It is widely used in process industries, automotive, and robotics.

Music Production Center

In music technology, MPC refers to a line of samplers and sequencers by Akai, beginning with the MPC60 in the late 1980s. These devices integrate sampling, sequencing, and control, and have influenced many genres.
