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.
The Average Indexed Monthly Earnings (AIME) is used in the United States' Social Security system to calculate the Primary Insurance Amount which decides the value of benefits paid under Title II of the Social Security Act under the 1978 New Start Method.

In retrospect, his recommendation of gluing slips onto bound sheets [12] was an innovation in moving from commonplace books to index cards as a form factor for scholarly information management. [13]: 212–225 Filing cabinet for paper slips in Vincent Placcius's De arte excerpendi (1689) [14]
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 ...
Full-time equivalent (FTE), or whole time equivalent (WTE), is a unit of measurement that indicates the workload of an employed person (or student) in a way that makes workloads or class loads comparable across various contexts. [1]
A fixed table of values for the n and k spectra of the SiO 2 and Si 3 N 4 films was used. With the n and k spectra of these films at hand, and using Rigorous Coupled Wave Analysis (RCWA), film thicknesses, various depths (heights) inside the trench, and CDs are then determined.
In 2010 about 250 plans participate in the program. [3] About 20 plans are nationwide or almost nationwide, such as the ones offered by some employee unions such as the National Association of Letter Carriers, by some employee associations such as GEHA, and by national insurance companies such as Aetna and the Blue Cross and Blue Shield Association on behalf of its member companies.
