The convective condensation level (CCL) results when strong surface heating causes buoyant lifting of surface air and subsequent mixing of the planetary boundary layer, so that the layer near the surface ends up with a dry adiabatic lapse rate. As the mixing becomes deeper, it will get to the point where the LCL of an air parcel starting at the ...
An adiabatic process (adiabatic from Ancient Greek ἀδιάβατος (adiábatos) 'impassable') is a type of thermodynamic process that occurs without transferring heat between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work and/or mass flow.
Adiabatic work is done without matter transfer and without heat transfer. In principle, in thermodynamics, for a process in a closed system, the quantity of heat transferred is defined by the amount of adiabatic work that would be needed to effect the change in the system that is occasioned by the heat transfer.
These techniques are not fit enough to meet today's power requirement. However, most research has focused on building adiabatic logic, which is a promising design for low power applications. Adiabatic logic works with the concept of switching activities which reduces the power by giving stored energy back to the supply.
James Stuart (1767) authored the first book in English with 'political economy' in its title, explaining it just as: . Economy in general [is] the art of providing for all the wants of a family, so the science of political economy seeks to secure a certain fund of subsistence for all the inhabitants, to obviate every circumstance which may render it precarious; to provide everything necessary ...
Engineering economics – a subset of economics that studies the behavior of individuals and firms in making engineering decisions regarding the allocation of limited resources. It is a simplified application of microeconomics in that it assumes elements such as price determination, competition and demand/supply to be fixed inputs.
Life-cycle cost analysis (LCCA) is an economic analysis tool to determine the most cost-effective option to purchase, run, sustain or dispose of an object or process. The method is popular in helping managers determine economic sustainability by figuring out the life cycle of a product or process.
In physical rehabilitation and sports training, the SAID principle asserts that the human body adapts specifically to imposed demands. [1] It demonstrates that, given stressors on the human system, there will be a Specific Adaptation to Imposed Demands (SAID). [2]
