Technological advances of position aware devices lead to a wealth of data documenting the lifelines of GPS-tracked animals, people, or vehicles. The integration of knowledge discovery techniques in GIS is thus an important research field with respect to the emerging volumes of tracking data. The motivation of this research is to find patterns in the way(More)
The overall goal of the ongoing project is to develop methods for spatio-temporal analysis of relative motion within groups of moving point objects , e.g. GPS-tracked animals. Whereas recent efforts of dealing with dynamic phenomena within the GIScience community mainly concentrated on modeling and representation, this research project concentrates on the(More)
INTRODUCTION Muscle symptoms in systemic sclerosis (SSc) may originate from altered skeletal muscle microcirculation, which can be investigated by means of blood oxygenation level dependent (BOLD) magnetic resonance imaging (MRI). METHODS After ethics committee approval and written consent, 11 consecutive SSc patients (5 men, mean age 52.6 years, mean SSc(More)
The traditional treatment of venous thromboembolism (VTE) has been use of heparin and vitamin K antagonists (VKA), and although shown to be effective, they have numerous limitations. New oral anticoagulants (NOACs) including direct thrombin (factor IIa) inhibitors (dabigatran) and selective factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) have(More)
Original field research data requires information about the positional accuracy of objects located in the field, expecially when analysed in the context of GIS. We present the results of a case study assessing the spatial accuracy of vegetation sampling data. The positional accuracy of a research grid consisting of adjacent squares of 20mx20m set up using a(More)
BACKGROUND This study sought to determine possible effects of different antiplatelet therapies on walking exercise performance in intermittent claudication. Aspirin, in contrast to clopidogrel, interferes with processes that increase collateral conductance in an ischemic animal model. METHODS AND RESULTS Patients with stable intermittent claudication were(More)
BACKGROUND Limited data exist concerning changes of renal perfusion directly after kidney transplantation. Colour-coded duplex sonography is the accepted method to assess kidney perfusion after transplantation. A widely used, although unspecific, Doppler parameter is the intrarenal resistance index (RI). The aim of this study was to clarify the influence of(More)
In mountainous areas, the use of DEM as environmental parameter in local and global models is widely accepted. Derived information like slope, aspect and others are often used as substitutes for missing data on specific habitat parameters to model the probability of species occurrence or absence. For habitat analysis of species, point observations were(More)
