In atomic physics and quantum chemistry, the Aufbau principle (/ ˈ aʊ f b aʊ /, from German: Aufbauprinzip, lit. ' building-up principle '), also called the Aufbau rule , states that in the ground state of an atom or ion , electrons first fill subshells of the lowest available energy , then fill subshells of higher energy.
Energy–maneuverability theory is a model of aircraft performance. It was developed by Col. John Boyd , a fighter pilot, and Thomas P. Christie , a mathematician with the United States Air Force , [ 1 ] and is useful in describing an aircraft's performance as the total of kinetic and potential energies or aircraft specific energy .
All these aspects of metabolism can be represented in energy units. [citation needed] The basic model of energy budget may be shown as: P = C - R - U - F or P = C - (R + U + F) or C = P + R + U + F All the aspects of metabolism can be represented in energy units (e.g. joules (J);1 calorie = 4.2 kJ). Energy used for metabolism will be
Energy modeling or energy system modeling is the process of building computer models of energy systems in order to analyze them. Such models often employ scenario analysis to investigate different assumptions about the technical and economic conditions at play.
Energy management includes planning and operation of energy production and energy consumption units as well as energy distribution and storage. Energy management is performed via Energy Management Systems (EMS) , which are designed with hardware and software components to implement the tasks.
The dynamic energy budget (DEB) theory is a formal metabolic theory which provides a single quantitative framework to dynamically describe the aspects of metabolism (energy and mass budgets) of all living organisms at the individual level, based on assumptions about energy uptake, storage, and utilization of various substances.
EnergyPlus [1] is a whole-building energy simulation program that engineers, architects, and researchers use to model both energy consumption — for heating, cooling, ventilation, lighting, and process and plug loads — and water use in buildings. Its development is funded by the U.S. Department of Energy Building Technologies Office. [1]
The Breakthrough Energy Model is a production cost model with capacity expansion algorithms and heuristics, originally designed to explore the generation and transmission expansion needs to meet U.S. states' clean energy goals. The data management occurs within Python and the DCOPF optimization problem is created via Julia. The Breakthrough ...
