A number of minimal problems of structure from motion for cameras with radial distortion have recently been studied and solved in some cases. These problems are known to be numerically very challenging and in several cases there exist no known practical algorithm yielding solutions in floating point arithmetic. We make some crucial observations concerning the floating point implementation of Gröbn
This thesis is divided into two distinct parts. The first part contains three chapters dealing with the analysis of duration data from an econometric perspective and with application to trade durations. The second part, consisting of the final chapter, focuses on the analysis of panel data and proposes a new test for poolability of the slope coefficients in cointegrated panel regressions. Chapter
Malignant glioma and glioblastoma multiforme form the largest group of highly malignant brain tumours, for which there is yet no definitive cure. Different approaches to treatment have been tried, in vain or with minimal benefit for the patient. In addition to surgery, radiation and chemotherapy, immunotherapy aiming at evoking an inflammatory reaction against the tumour itself has been tried. Imm

The classical problem of the Hebrew consecutive tenses is here attacked from a different angle: that of comparative language typology. The article explores parallel typological developments between West Semitic and early Indo-European as pertains to the creation of verbal forms by means of adding an “augment” or temporalizing particle to otherwise Aktionsart- or aspect-based morphological construc
