Fourier volume rendering (FVR) is a volume rendering method based on the Fourier slice theorem. With an n × n × n volume data, the FVR algorithm requires O(n2 log n) time to generate a result. Because it requires time less than O(n3) does, FVR is preferred for designing a real-time rendering algorithm with a preprocessing step. We improve upon our previous work. We demonstrate that a B-spline i...

Travel journals from different historical periods contain valuable insights that could be analyzed from different aspects and through that we can understand other people’s points of view about us. Description of different cities in travel literature represents French travelers’ views about these cities besides informing us about the quality and quantity of those cities at the times. “Represen...

A practical scheme is described for the real-time estimation of travel time across an arterial segment with multiple intersections. The scheme relies on matching vehicle signatures from wireless sensors. The sensors provide a noisy magnetic signature of a vehicle and the precise time when it crosses the sensors. A match (re-identification) of signatures at two locations gives the corresponding ...

We use detailed probe, video and detector data to characterize variability of travel times on (one link of) a major arterial street in the Northwest suburbs of Chicago. Major influences on variability are shown to be signal status and traffic volume, vehicles’ entry times of the link relative to the start of a red phase at the downstream intersection and the numbers of cars queued when they arr...

stanley g. weinbaum was one of the american science fiction writers of the 1920s and 1930s who anticipated virtual reality early in the development of the genre in the united states. the machine in weinbaum’s science fiction plays a crucial role in the production of virtual space and time. not only does weinbaum’s gadgetry function within the domain of spatial alterity, but they also provide te...

The flexibility of bus rapid transit (BRT) in scheduling is one of the greatest differences with traditional buses. In order to improve BRT operation quality, the paper studied the headway optimization and scheduling combination of BRT vehicles. A model has been established to minimize passengers’ travel costs and vehicles’ operation cost, and constraints included passenger volume, time, and fr...
