Ultraviolet photoelectron spectroscopy (UPS) refers to the measurement of kinetic energy spectra of photoelectrons emitted by molecules that have absorbed ultraviolet photons, in order to determine molecular orbital energies in the valence region.
A mock-up of a TPS report cover sheet, created for the movie Office Space A TPS report (" test procedure specification ") is a document used by a quality assurance group or individual, particularly in software engineering , that describes the testing procedures and the testing process.

The run-time for a battery-operated UPS depends on the type and size of batteries and rate of discharge, and the efficiency of the inverter. The total capacity of a lead–acid battery is a function of the rate at which it is discharged, which is described as Peukert's law. Manufacturers supply run-time rating in minutes for packaged UPS systems.
Condition monitoring by a simple head-flow test near duty point using repeatable measurements has long been used but could be more widely adopted. An extension of this method can be used to calculate the best time to overhaul a pump based on balancing the cost of overhaul against the increasing energy consumption that occurs as a pump wears.
DuPont's CPM was invented at roughly the same time as PERT. PERT Summary Report Phase 2, 1958. Initially PERT stood for Program Evaluation Research Task, but by 1959 was renamed. [4] It had been made public in 1958 in two publications of the U.S. Department of the Navy, entitled Program Evaluation Research Task, Summary Report, Phase 1. [7] and ...
To determine the best testing option, the test Effectiveness ratio (e) is calculated for one or more assumptions based on the estimated Costs (C), Time spend on testing (T) and the estimated reduction (R) between the NPV values of the assumptions (P as a percentage of the NPV range).
The most basic element of a cost estimate and therefore the cost database is the estimate line item or work item. [3] An example is "Concrete, 4000 psi (30 MPa)," which is the description of the item. In the cost database, an item is a row or record in a table (of items) and the description is a column or field for that record.
