**Point spread function** — The point spread function (PSF) describes the response of an imaging system to a point source or point object. A related but more general term for the PSF is a system s impulse response. The PSF in many contexts can be thought of as the extended… … Wikipedia

**Source criticism** — This entry is about source evaluation (or information evaluation) in an interdisciplinary context and thus not limited to some discipline specific understanding of the term source criticism . A source (an information source) may be a document, a… … Wikipedia

**Point-to-Point Protocol over Ethernet** — PPPoE, Point to Point Protocol over Ethernet, is a network protocol for encapsulating Point to Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with ADSL services where individual users connect to the ADSL transceiver (modem) … Wikipedia

**Method of loci** — The method of loci (plural of Latin locus for place or location), also called the memory palace, is a mnemonic device introduced in ancient Roman rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero s De Oratore, and Quintilian s … Wikipedia

**Material Point Method** — The Material Point Method (MPM), is an extension of the Particle in cell (PIC) Method in computational fluid dynamics to computational solid dynamics, and is a Finite element method (FEM) based particle method. It is primarily used for multiphase … Wikipedia

**Newton's method** — In numerical analysis, Newton s method (also known as the Newton–Raphson method), named after Isaac Newton and Joseph Raphson, is a method for finding successively better approximations to the roots (or zeroes) of a real valued function. The… … Wikipedia

**Nonpoint source water pollution regulations in the United States** — Nonpoint source (NPS) water pollution regulations are environmental regulations that restrict or limit water pollution from diffuse or nonpoint effluent sources such as polluted runoff from agricultural areas in a river catchments or wind borne… … Wikipedia

**Monte Carlo method for photon transport** — Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of… … Wikipedia

**Vortex lattice method** — The Vortex lattice method, (VLM), is a numerical, Computational fluid dynamics, method used mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing, of an … Wikipedia

**Floating point** — In computing, floating point describes a method of representing real numbers in a way that can support a wide range of values. Numbers are, in general, represented approximately to a fixed number of significant digits and scaled using an exponent … Wikipedia
