A new conception of knowledge and knowledge conversions is introduced. It is represented by a knowledge cube, a three-dimensional model of knowledge with types, kinds and qualities, and allows a description of general knowledge conversions between those. Through this conception we gain a sound basis for knowledge management. We can describe knowledge-intensive business processes in a company, b...
S U M M A R Y We present a neural network approach to invert surface wave data for a global model of crustal thickness with corresponding uncertainties. We model the a posteriori probability distribution of Moho depth as a mixture of Gaussians and let the various parameters of the mixture model be given by the outputs of a conventional neural network. We show how such a network can be trained o...
Based on 2.91 million user sessions, this study analyzes the effect of user-generated social-shopping features on micro-conversions. In the authors’ specific case of a social shopping community (SSC), the authors define a micro-conversion as a visit to a product-detail page. These visits are a requisite for visits to participating online-shops (click-out) for which the operator of a SSC receive...
Gene conversion and conversion-associated reciprocal recombination have been studied in various Saccharomyces cerevisiae hybrids. In a sample of 11,023 unselected meiotic tetrads, 907 conversions were observed at the arg4, thr3, his1, and SUP6 loci. Of these conversions, 445 (or 49.1%) were associated with reciprocal recombination of bracketing markers no more than 20-centimorgans apart. For co...
[1] Stacking of approximately 1500 radial receiver functions recorded at about 80 broadband seismic stations deployed in southern Africa reveals systematic spatial variations in the ratio of crustal P and S wave velocities (F), crustal thickness (H), and the amplitude of the converted Moho phases (R). The eastern Zimbabwe and the southern Kaapvaal cratons are characterized by small H ( 38 km), ...
P waves from regional-distance earthquakes are complex and reverberatory, as would be expected from a combination of head waves, post-critical crustal reflections and shallow-incident P waves from the upper mantle. Although designed for steeply-incident teleseismic P waves, receiver functions (RFs) can also retrieve information about crustal structure from regional P. Using a new computation me...
The Moho discontinuity is one of the fundamental boundaries on Earth, separating crust from upper mantle. Arrival times seismic reflection and refraction data are used to estimate depth Moho, but nature remains illusive. We present a synthetic seismogram modelling study for suite possible velocity models oceanic lower transition zone (MTZ). For modelling, we have 45-km long multichannel streame...
