horizontal components. The duration is also always greater. In each band a general correlation is attempted between acceleration peaks, uniform duration, spectral shapes, magnitude, and source distances....

We define a spectrally compact operator between two spectrally normed spaces. We show that every spectrally compact operator is compact but the converse is not true in general. Some basic aspects of these operayors are also proved....

for spectral ratio of pP/P, previously. Quantitative comparison of the two sets of data gives preference to nearly equal imaginary components of bulk and rigidity moduli, in this region of upper mantle....

In this paper, we study the one-level Friedrichs model by using

the quantum time super-operator that predicts the excited state decay inside

the continuum. Its survival probability decays exponentially in time.

A new form of strong-motion accelerogram ("spectrally maximized record"

or "SMR") and its associated generalized spectrum are proposed for earthquake

engineering use. Parameters (e.g., spectral, duration, peak amplitude...

measure for classifying protein conformational states using spectral representation

and Wigner’s D-functions. Predictions based on the new measure are in good agreement with

conformational states of proteins. These results could also...

We intoduce spectrally compact operators. We show that these operators are compact and spectrally bounded....
