## Standard Model

The **Standard Model** of particle physics is a theory concerning the electromagnetic , weak , and strong nuclear interactions, which mediate the dynamics of the known subatomic particles. Developed throughout the mid to late 20th century, the current formulation was finalized in the mid 1970s

## Standard Boolean model

The Boolean **model** of information retrieval (BIR) [ 1 ] is a classical information retrieval (IR) **model** and, at the same time, the first and most adopted one. It is used by virtually all commercial IR systems today. Contents 1 Definitions 2 Example 3 Advantages 4 Disadvantages

## Standard data model

A **standard** data **model** or industry **standard** data **model** (ISDM) is a data **model** that is widely applied in some industry, and shared amongst competitors to some degree. They are often defined by database vendors or operating system vendors and thus used by default whether suitable for

## Standard user model

A **standard** user **model** is a **standard** data **model** of a service end user . In theory, it permits a wide range of adaptive infrastructure , especially software , to adapt to a single human user's characteristics, e.g. preferred language , quality of eyesight including large print or color

## Non-standard model

In **model** theory , a discipline within mathematical logic , a non **standard model** is a **model** of a theory that is not isomorphic to the intended **model** (or **standard model** ). If the intended **model** is infinite and the language is first-order , then the Löwenheim-Skolem theorems guarantee

## Standard Model (cryptography)

In cryptography the **standard model** is the **model** of computation in which the adversary is only limited by the amount of time and computational power available. Other names used are bare **model** and plain **model** . Cryptographic schemes are usually based on complexity assumptions , which

## Noncommutative standard model

In theoretical particle physics , the non-commutative **Standard Model** , mainly due to the French mathematician Alain Connes , uses his noncommutative geometry to devise an extension of the **Standard Model** to include a modified form of general relativity . This unification implies a few
