Free-energy perturbation (FEP) is a method based on statistical mechanics that is used in computational chemistry for computing free-energy differences from molecular dynamics or Metropolis Monte Carlo simulations. The FEP method was introduced by Robert W. Zwanzig in 1954. [1]

Front-end loading (FEL), also referred to as Front-End Engineering Design (FEED), Front End Planning (FEP), pre-project planning (PPP), and early project planning, is the process for conceptual development of projects in processing industries such as upstream oil and gas, petrochemical, natural gas refining, extractive metallurgy, waste-to-energy, biotechnology, and pharmaceuticals.
Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
A front-end processor (FEP), or a communications processor, is a small-sized computer which interfaces to the host computer, a number of networks, such as SNA, or a number of peripheral devices, such as terminals, disk units, printers and tape units.
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...

The linear generator also allows the control of the resistance force, and therefore a better control of the piston's movement and of the reaction. The total efficiency (including mechanical and generator) of free-piston linear generators can be significantly higher than conventional internal combustion engines and comparable to fuel cells.
