Meteorites, intensity and magnitude

Contrast and range effects for category, magnitude and labeled magnitude scales in judgements of sweetness intensity.

The labeled magnitude scale (LMS) is a verbally anchored quasi-logarithmically spaced response scale with properties similar to magnitude estimation. Three experiments examined whether the LMS showed context effects similar to those found with magnitude estimation and category scales. Two versions of the LMS were used, one anchored at the high end to the strongest imaginable sweetness and the o...

Quantitative expression on drought magnitude and disaster intensity

According to the calculation of wind scale and earthquake magnitude, this paper puts forward the concept of drought magnitude and disaster intensity and lays out a new method by quantitative calculation. Drought magnitude is the quantitative index that describes the scale of a drought, and disaster intensity of drought is the quantitative index to describe the loss caused by a drought. Both ind...

Individual magnitude estimates for various distributions of signal intensity.

Magnitude estimates of loudness were collected for several variations in the schedule of signal presentations. For wide ranges (about 50 dB centered a t 65 dB), the conditions were: random selection of 21 signals equally spaced in decibels, constrained selection so that each signal was used equally often but successive signals were always close together, constrained selection in which successiv...

Image Analysis of 2D X-ray Intensity Maps: Element Abundances, Mineralogy, and Modal Analysis of Meteorites

X-ray mapping is increasingly used in the geological sciences for qualitative observations of textures, mineral zoning, and element distribution among rock components [1-4]. We combine mapping with an aggressive program of image analysis in deepening our understanding of the early solar system through the analysis of chondritic meteorites [5, 6]. Chondrites are “sediments” that accreted in the ...
