With the deployment of multi-modality and large-scale sensor networks for monitoring air quality, we are now able to collect large and multi-dimensional spatio-temporal datasets. For these sensed data, we present a comprehensive visual analysis approach for air quality analysis. This approach integrates several visual methods, such as map-based views, calendar views, and trends views, to assist...

 In this paper, Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) thin films were deposited on single crystal SrTiO3 (STO) (100) by pulsed laser deposition (PLD) technique at different pressures of oxygen. Crystal structure of bulk and thin film samples was studied by x-ray diffraction (XRD). The XRD results indicate that both bulk and thin film samples have cubic structures. AFM micrographs showed an increase i...

Secular trends in the facial skull over three Central European samples spanning more than 13 centuries were examined. Data were 43 conventional cephalometric landmark points for samples dating from 680 to 830 AD (29 male Avars), from the mid-19th century (49 adult Hapsburg Monarchy males), and from the 20th century (54 living Austrian young adult males). Analyses by standard methods of geometri...

Adaptive control is challenging in real-world applications such as robotics. Learning has to be rapid enough to be performed in real time and to avoid damage to the robot. Models using linear function approximation are interesting in such tasks because they offer rapid learning and have small memory and processing requirements. This makes them suitable as adaptive controllers in nonstationary e...

Short linear trends can be sensitive to the chosen start and end points. An obvious 8 question is to what extent is the observed cooling over the North Atlantic over the 20059 2014 period sensitive to inter-annual variability, especially the anomalous winter of the 1

This article reports data concerning the Internet-related activities and interest for Ironman Triathlon competition. Google Trends (GT) was used and mined from 2004 onwards. The interest for Ironman Triathlon was found to be cyclic over time. The Triathlon-related Internet activities negatively correlated with the number of finishers per year (Pearson׳s correlation r=-0.690, p-value<0.05), whil...
