McGraw Hill Financial, Inc. is an American publicly traded corporation headquartered in Rockefeller Center in New York City. Its primary areas of business are financial, publishing, and business services.
The design and planning of the physical environment of an activity to best support the execution of this activity. The activity may be one of many different types, such as manufacturing (plant layout), health care (hospital layout), logistics (warehouse design), transportation (airport layout), and services (bank layout, stadium layout).
Industry:Science
The decomposition of matter due to absorption of incident light. When photolysis occurs, it causes definite changes in the chemical composition of the illuminated material. For example, illumination of microcrystals of silver bromide embedded in gelatin results in formation of metallic silver, and is the basis of the photographic process.
Industry:Science
The determination of the size of a physical quantity by comparison with a standard. All physical measurement is ultimately based on measurement unit standards defined by the SI-metric system. Metric units are the foundation from which all other measurement units are derived, even the conventional nonmetric units used by the United States.
Industry:Science
Storage, usually in great quantities, of crude oil and natural gas after production from natural reservoirs. Large amounts of refined products are stored as well. Storage is necessary to meet seasonal and other fluctuations in demand; for efficient operation of producing equipment, pipelines, tankers, and refineries; and for emergency use.
Industry:Science
The attribute of two or more waves, or parts of a wave, whose relative phase is nearly constant during the resolving time of the observer. The concept has been developed most extensively in optics, but is applicable to all wave phenomena.
Industry:Science
The emission and propagation of energy; also, the emitted energy itself. The etymology of the word implies that the energy propagates rectilinearly, and in a limited sense, this holds for the many different types of radiation encountered.
Industry:Science
The deformations or movements of a structure and its components, such as beams and trusses, from their original positions. It is as important for the designer to determine deflections and strains as it is to know the stresses caused by loads.
Industry:Science
The equipment used to receive the transmitted modulated radio-frequency signals and produce synchronized visual images and sound for entertainment or educational purposes. The radio-frequency portion operates on the superheterodyne principle.
Industry:Science
The difference in potential between an excited atomic or molecular state and the ground state. The term is most generally used in connection with electron excitation, but it can be applied to excited molecular vibrational and rotational states.
Industry:Science
The description of natural phenomena in mathematical form. It is impossible to separate theoretical physics from experimental physics, since a complete understanding of nature can be obtained only by the application of both theory and experiment.
