The two heat maps to the right, labeled "Data Analysis Heat Map Example," show different ways in which one may present genomic data over a specific region (Hist1 region) to someone outside the field of biology so they have a better understanding of the general concept a biologist or data scientist are trying to present.
The rank of coal is correlated with its geologic history, as described in Hilt's law. In the ASTM system, any coal with more than 69% fixed carbon is classified by its content of carbon and volatiles. Coal with less than 69% fixed carbon is classified by its heating value. Volatiles and carbon are on a dry mineral free base; heating value is ...
Coal quality parameters of greatest interest include ash, moisture, sulfur, and energy density (also known as heat content). Although most coal operations can obtain this information about coal quality by taking physical samples, preparing the samples, and analyzing them with laboratory equipment, these processes often involve a time lag of up ...
Comparison of first and second heat data collected at consistent heating rates can allow the analyst to learn about both polymer processing history and material properties. (see J.H.Flynn.(1993) Analysis of DSC results by integration. Thermochimica Acta, 217, 129-149.) [citation needed]
US coal production had major tonnage peaks in 1918, 1947, and 2008. United States annual mined coal tonnage (black) and BTU content (red), 1980–2012, from US EIA. Although Hubbert's analysis in 1956 projected total extraction to peak in about 2150, [22] records show that extraction reached an energy peak in 1998 and a tonnage peak in 2008. [23]
This is a list of countries by coal production ranking countries with coal production larger than 5 million tonnes as of 2023. Coal production (million tonnes) Country
In photometry, luminous intensity is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle, based on the luminosity function, a standardized model of the sensitivity of the human eye. The SI unit of luminous intensity is the candela (cd), an SI base unit.
[c 1] The photopic includes the CIE 1931 standard [c 2] (solid), the Judd–Vos 1978 modified data [c 3] (dashed), and the Sharpe, Stockman, Jagla & Jägle 2005 data [c 4] (dotted). The horizontal axis is wavelength in nm. A luminous efficiency function or luminosity function represents the average spectral sensitivity of human visual ...
