Utilization of SAR and optical remote sensing data for habitat conservation in the tropical forest of Brazil

Autor: S. Saatchi, K. Alger, M. Siquiera De Araujo, Ruth DeFries, J. Dietz, R. Rice, W. Lawrence, L.A. Dietz

Publikováno v: 1995 International Geoscience and Remote Sensing Symposium, IGARSS '95. Quantitative Remote Sensing for Science and Applications.

Only a few percent of the original vegetation cover of the Atlantic Forest of Brazilremains due to agricultural development. This unique ecosystem has many endangered endemic species, the remaining populations of which are isolated in a few remaining

Conversion of Hanford site well locations to Washington coordinate system of 1983, South Zone 1991 (WCS83S)

Autor: L.A. Dietz, R.A. Burnett, S. Tzemos

Past construction and survey practices have resulted in the use of multiple local coordinate systems for measuring and reporting the horizontal position of wells and other facilities and locations on the Hanford Site. This report describes the develo

137Cs and 134Cs half-lives determined by mass spectrometry

Autor: C.F. Pachucki, L.A. Dietz

Publikováno v: Journal of Inorganic and Nuclear Chemistry. 35:1769-1776

We have used an internal standard technique and the precision of ion-counting mass spectrometry to follow the decay of 137Cs for a period of 11 yr. Our final value for the 137Cs half-life is 30·174 yr±an uncertainty (precision) of 0·034 yr at the

General method for computing the statistics of charge amplification in particle and photon detectors used for pulse counting

Autor: L.A. Dietz

Publikováno v: International Journal of Mass Spectrometry and Ion Physics. 5:11-19

A general method is given for computing output pulse-height distributions for a wide variety of multistage pulse-counting detectors used in mass spectrometry and in scintillation spectrometry. Calculations are simple, mathematically accurate and requ

Single‐Electron Response of a Porous KCl Transmission Dynode and Application of Polya Statistics to Particle Counting in an Electron Multiplier

Autor: L.R. Hanrahan, A.B. Hance, L.A. Dietz

Publikováno v: Review of Scientific Instruments. 38:176-183

The single electron statistics of a porous KCl transmission dynode are studied experimentally. Pulse amplification for subsequent analysis in a multichannel analyzer is obtained by coupling the output of the transmission dynode to a 14 stage electron
