Volume visualization techniques are often applied to sampled data obtained from MRI and CT-scans, as well as to simulated data computed by computational fluid dynamics (CFD) methods. In these and many other scientific visualization applications, a sequence of images is animated by incrementally rotating a volumetric object about its center, so that the(More)
We propose an approach for real-time sentiment-based anomaly detection (RSAD) in Twitter data streams. Sentiment classification is used to split the data into independent streams (positive, neutral, and negative), which are then analyzed for anomalous spikes in the number of tweets. Four approaches for evaluating the data streams are studied, along with the(More)
