assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Geodynamo theory and simulations
80 years ago, Joseph Larmor planted the seed that grew into today’s imposing body of knowledge about how the Earth’s magnetic field is created. His simple idea, that the geomagnetic field is the result of dynamo action in the Earth’s electrically conducting, fluid core, encountered many difficulties, but these have by now been largely overcome, while alternative proposals have been found to be ...

متن کاملGeodynamo Simulations—how Realistic Are They?
■ Abstract The past seven years have seen significant advances in computational simulations of convection and magnetic field generation in the Earth’s core. Although dynamically self-consistent models of the geodynamo have simulated magnetic fields that appear in some ways quite similar to the geomagnetic field, none are able to run in an Earth-like parameter regime because of the considerable ...
متن کاملGeodynamo Simulations under Earth-like Conditions
A number of dynamo simulations were performed during 2005 based on a Spectral Transform Method (STM). In one series of geodynamo simulations, the Ekman (Ek) and the Rayleigh (Ra) number dependences of the dynamo action were examined in detail. The change of the pattern of the fluid motion was observed as a function of Ra at Ek = 4 × 10–5.. The dynamo simulations at the lower value of Ek = 4 × 1...
