In addition, this method is somewhat time consuming. A simple alternative is to assume that all of the grains in the sample are composed of quartz (ρ= 2.65 g · cm−3) and that all thepore spaceis filled when wet. Under these assumptions: ...
Alight sourceis a real physical source of light, such as the sun or any type oflight bulb. Anilluminantis a plot of the relative energy versus wavelength and these are different for various light sources. Several common illuminants used in color science are: ...
This definition sets the range function as $${\delta}^{(\sigma )}({\mathbf{x}},{\mathbf{x}}_{a}) \equiv \left\{ {\begin{array}{*{20}{l}} {\frac{1}{A_{b}}} \hfill & {{\mathrm{if}}\,{\mathbf{x}}\,{\mathrm{and}}\,{\mathbf{x}}_{a}\,{\mathrm{are}}\,{\...
In this section, we introduce the basic concepts and some knowledge about the Bloch sphere and present the definition of the incoherent-coherent state [34–36]. 3.1 Bloch sphere Comparing the 0 and 1 of classical bits, the two possible states of a single qubit are \(|0\rangle \) and \...
Considering the definition of density resistance, whereby a maize variety has comparatively high single-plant yields at high densities, and the results of the analysis, the density resistance of the upright-leaf maize varieties (Xianyu 335, Denghai 661, and Zhengdan 958) was higher than that ...
WebCL is currently in the API definition phase, and has three popular open source implementations; Samsung, Nokia, and Motorola [36]. For our purpose of parallel skin lesion border detection, we use Nokia's WebCL implementation. A goal of WebCL is to provide a platform for a large ...
Density-dependent effects across biological levels.aA simple functional definition for the terminology of density in insects. We considered low density studies that investigated single individuals (in butterflies) or small groups (in flies) and high density, studies that investigated large groups, crowdin...
(each point in space belongs to many atoms, with its own share) was not very useful for crystal engineering. A hard space definition of the building blocks is much preferable. Therefore, he defined a molecule in a crystal as the, unique, region of space whoseprocrystaldensity has at least...
where Ts is the kinetic energy of the non-interacting A-nucleon system, EH is a Hartree energy, and Exc denotes the exchange–correlation energy which, by definition, contains everything else—all the many-body effects. The corresponding local exchange–correlation potential is defined by: (5...
(8.5) to the definition of kinetic energy derived from Newton's second law of motion, KE=12mv2, it is obvious that the element mass matrix [m]e can be written as shown in Eq. (8.6). This equation forms the basis for calculating the consistent element mass matrix. (8.6)[m]e=∫Ve...
