  2. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    In the SI system, the unit is the pascal (Pa) (or a multiple thereof, often megapascals (MPa), using the mega-prefix); or, equivalently to pascals, newtons per square metre (N/m 2). L: LDD: limited dimension drawing: An implementation of model-based definition that still uses a 2D drawing, but only containing critical information. All ...

  3. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    The parentheses can be omitted if the input is a single numerical variable or constant, as in the case of sin x = sin(x) and sin π = sin(π). Traditionally this convention extends to monomials; thus, sin 3x = sin(3x) and even sin 1 / 2 xy = sin(xy/2), but sin x + y = sin(x) + y, because x + y is not a monomial. However, this convention is not ...

    en.wikipedia.org/wiki/Numerical_Electromagnetics...

    The Numerical Electromagnetics Code, or NEC, is a popular antenna modeling computer program for wire and surface antennas. It was originally written in FORTRAN during the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. The code was made publicly available for general use and has subsequently been ...

  5. Modular arithmetic - Wikipedia

    en.wikipedia.org/wiki/Modular_arithmetic

    Time-keeping on this clock uses arithmetic modulo 12. Adding 4 hours to 9 o'clock gives 1 o'clock, since 13 is congruent to 1 modulo 12. In mathematics, modular arithmetic is a system of arithmetic for integers, where numbers "wrap around" when reaching a certain value, called the modulus. The modern approach to modular arithmetic was developed ...

  7. Lorenz system - Wikipedia

    en.wikipedia.org/wiki/Lorenz_system

    By comparison, based on the concept of attractor coexistence within the generalized Lorenz model and the original Lorenz model (), Shen and his co-authors proposed a revised view that “weather possesses both chaos and order with distinct predictability”. The revised view, which is a build-up of the conventional view, is used to suggest that ...

  8. Random number generation - Wikipedia

    en.wikipedia.org/wiki/Random_number_generation

    Dice are an example of a mechanical hardware random number generator. When a cubical die is rolled, a random number from 1 to 6 is obtained. Random number generation is a process by which, often by means of a random number generator (RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated.
