High power density electrodes for Carbon supercapacitor applications [PDF]

open access: yes, 2005
This paper presents results obtained with 4 cm2 Carbon/Carbon supercapacitors cells in organic electrolyte. In the first approach, a surface treatment for Al current collector foil via the sol–gel route has been used in order to decrease the Al/active ...

Design of a high power density ultra-thin switching power supply

open access: yesDianzi Jishu Yingyong, 2021
The planar transformer has the advantages of small size, low leakage inductance, low conversion efficiency, and good heat dissipation performance. The design scheme of the planar transformer is very suitable for the design of ultra-thin switching power ...

Rural to Urban Population Density Scaling of Crime and Property Transactions in English and Welsh Parliamentary Constituencies [PDF]

open access: yes, 2016
Urban population scaling of resource use, creativity metrics, and human behaviors has been widely studied. These studies have not looked in detail at the full range of human environments which represent a continuum from the most rural to heavily urban ...

Scattering Mechanisms in a High Mobility Low Density Carbon-Doped (100) GaAs Two-Dimensional Hole System [PDF]

open access: yes, 2011
We report on a systematic study of the density dependence of mobility in a low-density Carbon-doped (100) GaAs two-dimensional hole system (2DHS). At T= 50 mK, a mobility of 2.6 x 10^6 cm^2/Vs at a density p=6.2 x 10^10 cm^- was measured.

Viscous timescale in high mass X-ray binaries [PDF]

open access: yes, 2011
Context: Low mass X-ray binaries were found to have very low frequency breaks in their power density spectra below which the power density spectra are nearly in white noise structure and at higher frequencies they approximately follow the $P_\nu \propto \

Higher order moments of the density field in a parameterized sequence of non-gaussian theories [PDF]

open access: yes, 1998
We calculate the higher order moments in a sequence of models where the initial density fluctuations are drawn from a chi^2_nu distribution with a power-law power spectrum.
