This paper presents a complex heuristic method for the evaluation of fetal heart sounds, applying simultaneously several algorithms, where autocorrelation technique has been completed with wavelet transform and matching pursuit methods. In this way, more reliable rate variability can be achieved further parameters cardiac operation assessed in addition to conventional cardiotocographic examination. also comprises those parameters, which investigated only long-term or continuous monitoring,...
One of the most important problems in data mining is frequent itemset mining. It requires very large computation and I/O traffic capacity. For that reason several parallel distributed algorithms were developed. Recently mapreduce processing paradigm unavoidable porting current to focus. In this paper a substantial their implementations are introduced investi-gated. An algorithm improvement also proposed analyzed.
Abstract Targeted spatial transcriptomics methods capture the topology of cell types and states in tissues at single cell- subcellular resolution by measuring expression a predefined set genes. The selection an optimal probed genes is crucial for capturing interpreting signals present tissue. However, current selections often rely on marker genes, precluding them from detecting continuous or novel states. We Spapros, end-to-end probe pipeline that optimizes both specificity type...
Abstract In this paper, we present a fast and efficient technique for detecting identifying the slippage twisting motion of touching objects. This kind action cannot be detected with tactile sensors sensing only normal (perpendicular) component forces acting between surfaces.
