Energy levels Cool stars have very few hydrogen atoms in the n = 2 level and so give weak Balmer lines. Very hot stars have more atoms in the n = 3 level. ‘A’ class stars have the right temperature for most of the electrons to be in the n = 2 level. ...
Spatial features:Spatial features are edge andtexture features. These features help to detect foreground objects that camouflage with the background and suppress shadows. Spatial features are however not applicable to non-stationary background objects atpixel levelsince the correspondingspatial featuresvary ...

Emergent quasiparticles with a Dirac dispersion in condensed matter systems can be described by the Dirac equation for relativistic electrons, in analogy with Dirac particles in high-energy physics. For example, electrons with a Dirac dispersion have been intensively studied in electronic systems such ...
Spectral Indices derived from multispectral remote sensing products are extensively used to monitor Earth system dynamics (e.g. vegetation dynamics, water bodies, fire regimes). The rapid increase of proposed spectral indices led to a high demand for cat
Section4). Detecting this signal extends our grasp on primordial density perturbations by over three orders of magnitude in scale, covering epochs that cannot be probed directly in any other way.A non-detection at this level would be a serious challenge forΛCDM,immediately requiring new physics....

of the base algorithms are necessary. IHPS/CHOMPS/ENN contain a well developed set of algorithms designed for fast processing. They provide indications of the presence and estimates of the concentration of the sample constituents. The limits of the algorithms are determined by the physics of the ...
1), was adopted by Cannon for the publication of the HD catalogue, the ordering of the first three spectral classes was complicated in earlier work by the presence of then unidentified lines from He I and He II. The discovery of helium came in 1868 with the observation by Norman Lockyer ...
