Fractal Image Compression on MIMD Architectures II: Classification Based Speed-up Methods
Since fractal image compression is computationally very expensive, speed-up techniques are required in addition to parallel processing in order to compress large images in reasonable time. In this paper we discuss parallel fractal image compression algorithms suited for MIMD architectures which employ block classification as speed-up method
Optimization of 3-D Wavelet Decomposition on Multiprocessors
In this work we discuss various ideas for the optimization of 3-D wavelet/subband decomposition on shared memory MIMD computers. We theoretically evaluate the characteristics of these approaches and verify the results on parallel computers. Experimental results are conducted on a shared memory as well as a virtual shared memory architecture
Predicting Pathology in Medical Decision Support Systems in Endoscopy of the Gastrointestinal Tract
Since medical endoscopy is a minimally invasive and relatively painless procedure, allowing to inspect the inner cavities of the human body, endoscopes play an important role in modern medicine. In medica
Liposome Technology for Industrial Purposes
Liposomes, spherical vesicles consisting of one or more phospholipid bilayers, were first described in the mid 60s by Bangham and coworkers. Since then, liposomes have made their way to the market. Today, numerous lab scale but only a few large-scale techniques are available. However, a lot of these methods have serious limitations in terms of entrapment of sensitive molecules due to their exposure to mechanical and/or chemical stress. This paper summarizes exclusively scalable techniques and focuses on strengths, respectively, limitations in respect to industrial applicability. An additional point of view was taken to regulatory requirements concerning liposomal drug formulations based on FDA and EMEA documents
