Magnitude of Excitation Energy and Energy Transfer by Collision

Physical Review, 1954
Energy transfer by collision in fluorescent solutions is found to drop sharply when the excitation energy of the solute molecule is very close to or below that of the transferring molecule. The results indicate that energy is transferred only when molecules are close to each other as in collision.

BIOMASS ENERGY: THE MAGNITUDE OF THE POSSIBLE RESOURCE

2022
It is widely acknowledged that biofuels, whether usage of fluid, or hard fuel, electrical energy, have the potential to provide the bulk, anticipated renewable energy supply for future. The fundamental processes i.e., thermal, biological, and physical change can be used to create biofuels.

Reply to "Magnitude of energy dissipation in fission"

Physical Review C, 1980
We contend that the method of Ramamurthy et al. is based on a misconception of the energy release at scission. Low dissipation (of less than 10 MeV) in /sup 252/Cf(sf) follows from a proper evaluation.

Earthquake: Magnitudes, Energy, and Moment

2015
Corner frequency The frequency fc at which the curve that represents the Fourier amplitude spectrum of a signal abruptly changes its slope (see Fig. 4). For earthquakes, this frequency is related to the seismic source properties such as fault size, stress drop in the source volume, rupture velocity, and related rupture duration.

Energy-based VAD with grey magnitude spectral subtraction

Speech Communication, 2009
In this paper, we propose a novel voice activity detection (VAD) scheme for low SNR conditions with additive white noise. The proposed approach consists of two parts. First, a grey magnitude spectral subtraction (GMSS) is applied to remove additive noise from a given noisy speech. By this doing, an estimated clean speech is obtained.

A magnitude-energy relation for large earthquakes

Bulletin of the Seismological Society of America, 1969
Abstract A relation between the magnitude of a shallow earthquake and the rupture parameters is derived by using a result of dislocation theory and assumptions as suggested from model studies: the average of the pre- and post-shock stresses on a fault and the seismic efficiency are approximately constant.

Energy and Magnitude: A Historical Perspective

Pure and Applied Geophysics, 2018
We present a detailed historical review of early attempts to quantify seismic sources through a measure of the energy radiated into seismic waves, in connection with the parallel development of the concept of magnitude. In particular, we explore the derivation of the widely quoted “Gutenberg–Richter energy–magnitude relationship” 1

On frequency magnitude and energy of significant Indian earthquakes

pure and applied geophysics, 1970
Frequency, magnitude and energy of Indian earthquakes with magnitude greater than 5 has been studied. The Indian regions can be divided into three main seismically active regions, viz. 1. Delhi and Himalayan region, 2. Assam region and 3. Koyana region which includes southwest India.

The magnitude of the energy imbalance in obesity is generally underestimated

International Journal of Obesity, 2008
As the efforts to defeat the obesity epidemic amplify around the world, it is important to understand the true magnitude of the energy imbalance associated with excess weight. The energy imbalance in a weight gain situation is the difference between the number of calories ingested and the total caloric expenditure on the same day.

The influence of acoustic phonons on the magnitude of energy fluctuations in DNA

Ferroelectrics, 1980
Abstract It is shown that acoustic phonons can play an important role in determining the magnitude of energy fluctuations along the DNA molecule. This reflects heterogeneity in DNA flexibility associated with different stacking energies that stabilize various combinations of nucleotide sequences in its structure.
