Resonant Doppler Fourier domain optical coherence tomography (FDOCT) is a functional imaging tool for extracting tissue flow. The method is based on the effect of interference fringe blurring in spectrometer-based FDOCT, where the path difference between s ...
We discuss the use of Pade-Legendre interpolants as an approach for the postprocessing of data contaminated by Gibbs oscillations. A fast interpolation based reconstruction is proposed and its excellent performance illustrated on several problems. Almost n ...
Many attempts to engineer cellular metab. have failed due to the complexity of cellular functions. Math. and computational methods are needed that can organize the available exptl. information, and provide insight and guidance for successful metabolic engi ...
Gas absorption in packed columns was modelled, taking into account all heat effects for phys. gas absorption. Multicomponent diffusion effects were incorporated in terms of the film-factor concept. An algorithm of very stable convergence behavior was obtai ...
We present a new method for estimating heart motion from two-dimensional echocardiographic sequences by exploiting two ultrasound modalities: B-mode and tissue Doppler. The algorithmestimates a two-dimensional velocity field locally by using a spatial affi ...
We present a new framework to estimate and visualize heart motion from echocardiograms. For velocity estimation, we have developed a novel multiresolution optical flow algorithm. In order to account for typical heart motions like contraction/expansion and ...
Wavelet-based methods have become most popular for the compression of two-dimensional medical images and sequences. The standard implementations consider data sizes that are powers of two. There is also a large body of literature treating issues such as th ...
We describe the computation which resulted in the title of this paper. Furthermore, we give an analysis of the data collected during this computation. From this data, we derive the important observation that in the final stages, the progress of the double ...
The contribution deals with the determination of the curves of the annual number of lightning induced flashover vs. the critical impulse flashover voltage of the insulators, used by power engineers for the assessment of the lightning performance of distrib ...
