2. Helmholtz free energy - Wikipedia

   en.wikipedia.org/wiki/Helmholtz_free_energy

   e. In thermodynamics, the Helmholtz free energy (or Helmholtz energy) is a thermodynamic potential that measures the useful work obtainable from a closed thermodynamic system at a constant temperature (isothermal). The change in the Helmholtz energy during a process is equal to the maximum amount of work that the system can perform in a ...

3. Construction estimating software - Wikipedia

   Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [ 1 ] It is one of the oldest and broadest of the engineering branches.

5. Work sampling - Wikipedia

   en.wikipedia.org/wiki/Work_sampling

   Work sampling. Work sampling is the statistical technique used for determining the proportion of time spent by workers in various defined categories of activity (e.g. setting up a machine, assembling two parts, idle…etc.). [1] It is as important as all other statistical techniques because it permits quick analysis, recognition, and ...

6. Interpolation - Wikipedia

   en.wikipedia.org/wiki/Interpolation

   Interpolation. In the mathematical field of numerical analysis, interpolation is a type of estimation, a method of constructing (finding) new data points based on the range of a discrete set of known data points. [1][2] In engineering and science, one often has a number of data points, obtained by sampling or experimentation, which represent ...
