  2. The Power of 10: Rules for Developing Safety-Critical Code

    en.wikipedia.org/wiki/The_Power_of_10:_Rules_for...

    The ten rules are: [1] Avoid complex flow constructs, such as goto and recursion. All loops must have fixed bounds. This prevents runaway code. Avoid heap memory allocation. Restrict functions to a single printed page. Use a minimum of two runtime assertions per function. Restrict the scope of data to the smallest possible.

  3. Work function - Wikipedia

    en.wikipedia.org/wiki/Work_function

    The work function W for a given surface is defined by the difference [1] W = − e ϕ − E F , {\displaystyle W=-e\phi -E_{\rm {F}},} where − e is the charge of an electron , ϕ is the electrostatic potential in the vacuum nearby the surface, and E F is the Fermi level ( electrochemical potential of electrons) inside the material.

  4. MUMPS - Wikipedia

    en.wikipedia.org/wiki/MUMPS

    MUMPS ("Massachusetts General Hospital Utility Multi-Programming System"), or M, is an imperative, high-level programming language with an integrated transaction processing key–value database. It was originally developed at Massachusetts General Hospital for managing patient medical records and hospital laboratory information systems.

  5. Molybdenum disulfide - Wikipedia

    en.wikipedia.org/wiki/Molybdenum_disulfide

    MoS 2 in particle sizes in the range of 1–100 μm is a common dry lubricant. [34] Few alternatives exist that confer high lubricity and stability at up to 350 °C in oxidizing environments. Sliding friction tests of MoS 2 using a pin on disc tester at low loads (0.1–2 N) give friction coefficient values of <0.1. [35] [36]

  6. Function (computer programming) - Wikipedia

    en.wikipedia.org/.../Function_(computer_programming)

    A built-in function, or builtin function, or intrinsic function, is a function for which the compiler generates code at compile time or provides in a way other than for other functions. [23] A built-in function does not need to be defined like other functions since it is built in to the programming language. [24]

  7. Functor (functional programming) - Wikipedia

    en.wikipedia.org/wiki/Functor_(functional...

    Applying fmap (+1) to a binary tree of integers increments each integer in the tree by one. In functional programming , a functor is a design pattern inspired by the definition from category theory that allows one to apply a function to values inside a generic type without changing the structure of the generic type.

  9. Function composition (computer science) - Wikipedia

    en.wikipedia.org/wiki/Function_composition...

    Programmers frequently apply functions to results of other functions, and almost all programming languages allow it. In some cases, the composition of functions is interesting as a function in its own right, to be used later. Such a function can always be defined but languages with first-class functions make it easier.
