Underground muons from the direction of Cygnus X-3 (open access)

Underground muons from the direction of Cygnus X-3

We report on 3.2 years live time of underground muon observations taken between 1981 and 1989 using the Soudan 1 proportional tube detector, located at a depth of 1800 m water equivalent. The post-1984 observations are consistent with our earlier data on an excess signal apparently correlated with the Cygnus X-3 orbital period. The signal-to-background ratio in the entire data sample is 1 to 3 percent, depending on phase width. 10 refs., 2 figs., 1 tab.

Energy planning and management in developing countries: thoughts concerning a conceptual framework (open access)

Energy planning and management in developing countries: thoughts concerning a conceptual framework

The unique characteristics of the energy situation in developing countries imposes a unique set of requirements on analytical techniques used for energy planning. The urgency of the situation requires the rapid development and use of simplified models which make maximum use of available data but which can reflect the international energy context. Those techniques must also be able to deal with central energy/development issues such as energy equity or the energy implication of social equity policies, centralized vs. decentralized development, and urbanization.

Reaction rate calculations via transmission coefficients (open access)

Reaction rate calculations via transmission coefficients

The transmission coefficient of a wavepacket traversing a potential barrier can be determined by steady state calculations carried out in imaginary time instead of by real time dynamical calculations. The general argument is verified for the Eckart barrier potential by a comparison of transmission coefficients calculated from real and imaginary time solutions of the Schroedinger equation. The correspondence demonstrated here allows a formulation for the reaction rate that avoids difficulties due to both rare events and explicitly time dependent calculations. 5 refs., 2 figs.

Final report for hydrologic studies support: INTERCOMP code conversion (open access)

Final report for hydrologic studies support: INTERCOMP code conversion

Mass and energy balance errors noted in a number of IBM-executed problems are caused by the lack of precision in computing total mass and energy values for a domain. This problem is evident in domains constructed with highly variable mesh sizes during the early time of simulation. The machine round-off was corrected by double-precisioning certain calculations for mass and energy balance. Small differences that exist between the improved INTERCOMP code operating on an IBM machine and the old version on a CDC machine seem unimportant. The noted differences are greatest at an onset of physical system perturbation. These differences diminish rapidly with each succeeding time step. Comparisons with numerical and analytical solutions appear to prove authenticity of code results. Numerical comparisons with the CCC computer code on the Mobile experiment data demonstrate the advantage of using aquifer influence functions in place of an infinitely large mesh. The one-dimensional heat transfer in the overburden and underburden appears sufficiently accurate to describe aquifer heat losses.

Geothermal alteration of sediments in the Salton Sea scientific drill hole: Petrophysical properties and mass changes during alteration: Final report (open access)

Geothermal alteration of sediments in the Salton Sea scientific drill hole: Petrophysical properties and mass changes during alteration: Final report

This report has been divided into two sections. The first deals with the results of the petrophysical measurements, and the second concentrates on the distribution of alteration minerals and textures, and on a series of calculations of geochemical changes that occurred during alteration. 32 refs., 23 figs., 10 tabs.
