Background Regular physical activity over a long time period leads to a cardiac adaptation described as “athlete’s heart”. The purpose of this study was to determine the effects of intensive daily training in a specific type of sportsprofessional soccer, in regard to morphological and functional left ventricular parameters assessed by cardiac magnetic resonance imaging (CMRI) and to compare the...

This study develops an integrated data-driven and model-driven approach (template matching) that clusters the urban railroad point clouds into three classes of rail track, contact cable, and catenary cable. The employed dataset covers 630 m of the Dutch urban railroad corridors in which there are four rail tracks, two contact cables, and two catenary cables. The dataset includes only geometrica...

For generations of scholars and observers, the "transportation revolution," especially the railroad, has loomed large as a dominant factor in the settlement and development of the United States in the nineteenth century. There has, however, been considerable debate as to whether transportation improvements led economic development or simply followed. Using a newly developed GIS transportation d...

This paper describes how the combined use of OpenTimeTable, a schedule analysis program, and OpenTrack, a railroad network simulation program, can be used to help develop more robust timetables. The paper describes how these programs and additional statistical analysis was used to help identify causes of delay and evaluate solutions for reducing this delay on Zurich’s suburban rail network. Ope...
