Visualization to compare karate motion captures

Multi-dimensional time series from motion capture (MoCap) provide a rich source of data for human motion analysis, yet they are difficult to process and compare. We address MoCap data related to Karate katas, containing predefined sequences of movements, executed independently by several subjects with different timing and speed. We propose a combination of signal processing and data visualization techniques to analyze the misalignment between data from different subjects. We present a web app that implements this proposal, providing a visual comparison of time series, based on Dynamic Time Warping.XVII Workshop de Computación Gráfica.Red de Universidades con Carreras en Informátic

Simple quad domains for field aligned mesh parametrization

We present a method for the global parametrization of meshes that preserves alignment to a cross field in input while obtaining a parametric domain made of few coarse axis-aligned rectangular patches, which form an abstract base complex without T-junctions. The method is based on the topological simplification of the cross field in input, followed by global smoothing

Sistema di movimentazione del tracciatore a pixel del Precision Proton Spectrometer di CMS

Il presente lavoro descrive il sistema di movimentazione del tracciatore PPS dell'esperimento CMS. Scopo del sistema di movimentazione è quello di minimizzare la disuniformità di danneggiamento dei chip di lettura dei rivelatori. Il sistema è stato progettato e prodotto presso la Sezione di Genova dell'INFN. Vengono inoltre descritti alcuni test preliminari di funzionamento
