One-way endobronchial valves (EBVs) have been shown to relieve symptoms of emphysema, particularly in patients without collateral ventilation (CV) between the target and adjacent lobes. In this study, we investigated the ability of the bronchoscopic Chartis™ Pulmonary Assessment System to predict treatment response by determining the presence of CV. 80 EBV(More)
We present a framework for real-time animation of explosions that runs completely on the GPU. The simulation allows for arbitrary internal boundaries and is governed by a combustion process, a Stable Fluid solver, which includes thermal expansion, and turbulence modeling. The simulation results are visualised by two particle systems rendered using animated(More)
AIM OF THE STUDY The primary purpose of this study is to investigate if pretreatment plasma levels of vascular endothelial growth factor (VEGF) are predictive of the effect of celecoxib on survival in advanced non-small cell lung cancer (NSCLC) treated with palliative chemotherapy. A secondary objective is to describe the course of plasma VEGF levels during(More)
Norges teknisk-naturvitenskapelige universitet Institutt for datateknikk og informasjonsvitenskap Abstract Explosions play an important role in many games. Yet, as explosions are sudden and highly turbulent, animating visually pleasing and dynamic real-time explosions is a very complex task. We present a method for animating explosions completely on the(More)
