Quantifying the Influence of Route ChoiceOptimization on Emissions and Fuel Consumption
No full textGenetic algorithm-based route choice optimization techniques have recently demonstrated their potential to reduce the travel costs on the system level. In this context, the costs are reduced according to exactly one metric such as, e. g., the sum of all individual travel times. In the present study, we will investigate the tradeoff between the saved travel time and the additional costs in terms of higher emissions and a higher fuel consumption.Fachgespräch Inter-Vehicle Communication 2016, inter-veh-comm-2016, 31.03.2016 - 01.04.2016, Humboldt-Universität zu Berlin, pp 18-1

Determining and Visualizing Potential Sources of Floods
No full textIn this paper, we visually analyze spatio-temporal patterns of different hydrologic parameters relevant for flooding. On the basis of data from climate simulations with a high resolution regional atmosphere model, several extreme events are selected for different river catchments in Germany. By visually comparing the spatial distribution of the main contributions to the run-off along with their temporal evolution for a time period in the 20th and the 21th century, impacts of climate change on the hydrological cycle can be identified
Comparative Visualization Of Geospatial-Temporal Data
No full textThe amount of online data annotated with geospatial and temporal metadata has grown rapidly in the recent years. Social networks like Flickr and Twitter are popular providers of masses of such data, but are hard to browse. Many systems exist that can show the data’s geospatial distribution in a map widget and their temporal distribution in a time widget, allowing these widgets to become dynamic-query-like filters for data. We present a web application that combines several existing approaches and supports comparison of multiple, potentially large result sets of textual queries in a geospatial and temporal context with extended interaction capabilities. We validate our approach with several case studies and our tool’s learnability in a field experiment

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
