In this paper, we present a physically-based simulation framework to build up real-time Minimally invasive surgery (MIS) simulators using point-based techniques. In our framework, simulations of organ contacts, collisions, deformations and haptic feedbacks are all based on discrete physics points. We propose a new smoothed particle hydrodynamics (SPH)… (More)
The effectively large mirror size in a space telescope may be achieved by swarms of mirrors. In this paper, we present an analysis of such a space telescope, where a swarm of randomized micro-mirrors are combined to achieve the resolution comparable to a primary mirror equivalent to the entire distribution. The recorded speckle patterns, which vary randomly… (More)
Speckled images of a binary broad band light source (600-670 nm), generated by randomized reflections or transmissions, were used to reconstruct a binary image by use of multi-frame blind deconvolution algorithms. Craft store glitter was used as reflective elements. Another experiment used perforated foil. Also reported here are numerical models that… (More)
Palladium(II)-catalyzed dual C-H functionalization of indoles with cyclic diaryliodoniums was successfully achieved, providing a concise method to synthesize dibenzocarbazoles. In a single operation, two C-C bonds and one ring were formed. The reaction was ligand free and tolerated air and moisture conditions.
