A comparative study of scheduling techniques for multimedia applications on SIMD pipelines

Parallel architectures are essential in order to take advantage of the parallelism inherent in streaming applications. One particular branch of these employ hardware SIMD pipelines. In this paper, we analyse several scheduling techniques, namely ad hoc overlapped execution, modulo scheduling and modulo scheduling with unrolling, all of which aim to efficiently utilize the special architecture desi

Fitness in common buzzards at the cross-point of opposite melanin-parasite interactions

Melanin is one of the major pigments of vertebrates and has many suggested functions. Although it is supposed to have an antipathogenic effect, its relationship to infection with ecto- and endoparasites largely remains to be examined. The common buzzard Buteo buteo occurs in three eumelanin morphs which differ in their lifetime reproductive success. We examined the distribution of the blood-suckin

Widesight - a project aimed at improving peripheral vision

Our group of researchers from a variety of backgrounds has been investigating the possibility of improving vision for patients with central scotoma. So far, these patients have only been offered enlarging devices and training. We hope that new knowledge about the peripheral vision optics of the eye will result in improvements in image quality and that this can be helpful for people with low vision
