  2. Mathematical discussion of rangekeeping - Wikipedia

    en.wikipedia.org/wiki/Mathematical_discussion_of...

    [3] In addition to long range gunnery, the launching of torpedoes also requires a rangekeeping-like function. [4] The US Navy during World War II had the TDC, which was the only World War II-era submarine torpedo fire control system to incorporate a mechanical rangekeeper (other navies depended on manual methods). There were also rangekeeping ...

  7. Lists of physics equations - Wikipedia

    en.wikipedia.org/wiki/Lists_of_physics_equations

    In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.

  8. Population balance equation - Wikipedia

    en.wikipedia.org/wiki/Population_balance_equation

    Consider the average number of particles with particle properties denoted by a particle state vector (x,r) (where x corresponds to particle properties like size, density, etc. also known as internal coordinates and, r corresponds to spatial position or external coordinates) dispersed in a continuous phase defined by a phase vector Y(r,t) (which again is a function of all such vectors which ...

  9. Port state control - Wikipedia

    en.wikipedia.org/wiki/Port_State_Control

    Port state control (PSC) is an inspection regime for countries to inspect foreign-registered ships in port other than those of the flag state and take action against ships that are not in compliance. Inspectors for PSC are called PSC officers (PSCOs), and are required to investigate compliance with the requirements of international conventions ...
