Missing a trick: Karatsuba revisited
There are a variety of ways of applying the Karatsuba idea to multi-digit multiplication. These apply particularly well in the context where digits do not use the full word-length of the computer, so that partial products can be safely accumulated without fear of over ow. Here we re-visit the arbitrary degree version of Karatsuba and show that the cost of this little-known variant has been over...
متن کاملGeothermal Exploration Methods
A geothermal reservoir causes inhomogeneity in the physical properties of the subsurface geology due to the high changes in temperature. These physical properties can be ob‐ served by means of varying anomalies from geophysical observations from the surface. These physical properties include electrical conductivity, rock density, magnetic suscepti‐ bility, rock elasticity, and, finally, the tem...
متن کاملMissing a trick: Auditory load modulates conscious awareness in audition.
In the visual domain there is considerable evidence supporting the Load Theory of Attention and Cognitive Control, which holds that conscious perception of background stimuli depends on the level of perceptual load involved in a primary task. However, literature on the applicability of this theory to the auditory domain is limited and, in many cases, inconsistent. Here we present a novel "audit...
متن کاملApplication of Geochemical Methods in Geothermal Exploration
Subsurface waters have been classified into meteoric water, ocean water, evolved connate water, magmatic water and juvenile water. Geothermal water is mostly meteoric and oceanic water although andesitic waters near subduction areas often contain significant proportions of evolved connate and magmatic waters. Geothermal waters have been classified with respect to their anion and cation contents...
متن کاملReconnaissance exploration of potential geothermal sites in Kerman province, using Curie depth calculations
In this paper an indirect method is presented to detect potential geothermal sites in Kerman province, southeast Iran. Geothermal heat flux is one of the main parameters to be investigated in geothermal exploration programs. However, few direct heat flux measurements are available for Iran. Given the proved relation between Curie depths and heat flux, magnetic data can be used to calculate the ...
