By using an integrated dynamic model we are able to reconstruct the supply and gold price of the past (1920-2010) and this is used to predict the future supply of gold to the market and to make a forecast of the goldprice 2010-2100. The model was validated against field data for the period 1920-2010 and it performs well. The model GOLD is implemented in the STELLA® software and the model described

A number of Roman Marble heads in Swedish Royal possession since the 17th century may be traced back to the collection of the burgomaster Rockox in Antwerpen. Four of these occur in the famous painting by Frans Francken the Younger representing a feast in Nicholaas Rockox' home. Althoug more marble heads to be found in the Stockholm collection may be traced back to Rockox two of the heads in the p

Based chiefly on textual sources, the article treats of the nine planetary deities of Hinduism, their origin and historical development, major mythology, iconography, rituals, and their relation both to the greater Hindu pantheon and to astrological concepts.

We present a hierarchical traversal algorithm for stochastic rasterization of motion blur, which efficiently reduces the number of inside tests needed to resolve spatio-temporal visibility. Our method is based on novel tile against moving primitive tests that also provide temporal bounds for the overlap. The algorithm works entirely in homogeneous coordinates, supports MSAA, facilitates efficient

The text of the Skara Missal Compared to Other Liturgical Sources. A large number of printed sources have been consulted and compared with Skara Missal on a quntitative as well as qualitative basis; individual characteristics as well as the evident concordance with many identical readings have been noted and compiled. On the basis of comparisons of various paryers and prefaces it may first of all

REX is a Fortran program for analysis of spectra obtained in PIXE analysis. The underlying model is still under development; however, one year of experience has demonstrated REX’s capability to be a fast reliable tool. The modeling of the different components and effects of the physical model is briefly discussed. Evidence is shown that secondary effects mostly due to Compton-scattering in and aro

This contribution is about an entirely new approach to the study of knowledge. As an introductory remark, the classical research operations in the field of cognition are reviewed. Against this background, an application of David Hestenes theory of rotational dynamics is demonstrated with particular reference to text processing. Based on the mechanism of joints and links of the AaO machine, angular
