- domain engineering — (systems analysis) 1. The development and evolution of domain specific knowledge and artifacts to support the development and evolution of systems in the domain. Domain engineering includes engineering of domain models, components, methods and tools and may also include asset management. 2.

A reuse-based approach to defining the scope (domain definition), specifying the structure (domain architecture) and building the Assets (requirements, designs, software code, documentation) for a class of systems, subsystems or applications. Domain engineering can include domain definition, domain analysis, developing the domain architecture domain implementation.

- euclid's algorithm — (algorithm) (Or "Euclidean Algorithm") An algorithm for finding the greatest common divisor (GCD) of two numbers. It relies on the identity gcd(a, b) = gcd(a-b, b) To find the GCD of two numbers by this algorithm, repeatedly replace the larger by subtracting the smaller from it until the two numbers are equal. E.g. 132, 168 -> 132, 36 -> 96, 36 -> 60, 36 -> 24, 36 -> 24, 12 -> 12, 12 so the GCD of 132 and 168 is 12. This algorithm requires only subtraction and comparison operations but can take a number of steps proportional to the difference between the initial numbers (e.g. gcd(1, 1001) will take 1000 steps).
