Discretization, английский
- Дискретизация
- The process of putting values of a continuous set of data into groups so that there are a discrete number of possible states.
Discounting, английский
- Дисконтирование
- Discounting is a method for combining or de-emphasizing belief and probability functions, either by weighted averages of a set of functions or combining a single function with a vague or vacuous function. as an example of the latter, a belief function could be averaged with a belief function that assigns all of its mass to the entire frame of discernment. it can also be used to combine multiple experts belief functions that conflict with each other, unlike dempster`s rule of combination, which discards the probability mass assigned to conflicting subsets of the frame. see also: dempster`s rule of combination, frame of discernment.
- Calculating the present value of a future amount. discounting is opposite to compounding.
- A mathematical operation making monetary (or other) amounts received or expended at different points in time (years) comparable across time (see annex ii). the operator uses a fi xed or possibly time-varying discount rate (>) from year to year that makes future value worth less today. a descriptive discounting approach accepts the discount rates that people (savers and investors) actually apply in their day-to-day decisions (private discount rate). in a prescriptive (ethical or normative) discounting approach, the discount rate is fi xed from a social perspective, for example, based on an ethical judgement about the interests of future generations (social discount rate). in this report, potentials of renewable energy supplies are assessed using discount rates of , and %. dispatch (power dispatching / dispatchable): electrical power systems that consist of many power supply units and grids are governed by system operators. they allow generators to supply power to the system for balancing demand and supply in a reliable and economical way. generation units are fully dispatchable when they can be loaded from zero to their nameplate capacity without signifi cant delay. not fully dispatchable are variable renewable sources that depend on natural currents, but also large-scale thermal plants with shallow ramping rates in changing their output. see also balancing, capacity, grid. district heating (dh): hot water (steam in old systems) is distributed from central stations to buildings and industries in a densely occupied area (a district, a city or an industrialized area). the insulated two-pipe network functions like a water-based central heating system in a building. the central heat sources can be waste heat recovery from industrial processes, waste incineration plants, geothermal sources, cogeneration power plants or stand-alone boilers burning fossil fuels or biomass. more and more dh systems also provide cooling via cold water or slurries (district heating and cooling - dhc).
