The role of energy density

Lipids, 2003
AbstractDietary energy density (ED) appears to have a major influence on the regulation of food intake and body weight. If people consume a fixed weight of food each day, then high‐ED diets should be associated with high energy intakes and with overweight.

Density-dependent covariant energy density functionals

AIP Conference Proceedings, 2012
Relativistic nuclear energy density functionals are applied to the description of a variety of nuclear structure phenomena at and away fromstability line. Isoscalar monopole, isovector dipole and isoscalar quadrupole giant resonances are calculated using fully self-consistent relativistic quasiparticle randomphase approximation, based on the ...

High energy density capacitors

2004 12th Symposium on Electromagnetic Launch Technology, 2004., 2005
In the German Pulsed Power Components Program, Rheinmetall and Vishay started a joint effort to develop a high energy density capacitor for the 120 mm ETC gun demonstrator. Based on conventional metallized film technology a compact 120 kJ capacitor with an energy density of 2 MJ/m/sup 3/ was designed and tested with the electric requirements of the ETC

ELECTROMAGNETIC ENERGY DENSITY AND FLUX

Canadian Journal of Physics, 1952
Although Poynting's theorem receives general acceptance in the treatment of electromagnetic energy, an alternative theorem, Macdonald's, has equal claim to validity at the present state of our knowledge. In a comparison of many results derived from the two, Macdonald's theorem exhibits sufficient superiority to warrant its consideration more generally

Flat energy density antenna

Antennas and Propagation Society Symposium 1991 Digest, 2002
The authors present a feed circuit for the flat energy density antenna for mobile telephone, and measurement results on its input characteristics and radiation pattern at 1.5 GHz. The correlation coefficient between ring patch and notch antenna of less than 0.1 is small enough for diversity branches.

Energy Density and Power Density of Electrical Energy Storage Devices

1999
The relation between power and energy requirements in the operation of “prime movers” has long been an important topic in the engine industry, starting with the period of steam and improvements in the efficiency of the Newcomen atmospheric steam engine by Watt through his separate condenser, and the invention of indicator diagrams for recording ...

Four‐dimensional density and energy density functional

International Journal of Quantum Chemistry, 1984
AbstractThe relations based on an external one‐electron operator V(r) are examined from two view‐points, i.e., from the Hohenberg–Kohn approach and the four‐dimensional density concept introduced by Wilson and Frost, and extensively studied by Parr and Politzer. The object being to obtain, with the help of the Hellmann–Feynman theorem, new formulas for

Energy Density Theory

This paper explores the hypothesis that the mass of elementary particles results from variations in energy density within space. The proposed approach provides an explanation for fundamental interactions, dark matter and dark energy anomalies, Heisenberg's uncertainty principle, and offers an alternative to the concepts of space curvature and the Higgs
