Internet provides an interactive mode for information retrieval. But its bandwidth is narrow. TV can provide broadband service. Usually, it is not interactive. In China, the CATV (CAble TeleVision) is very popular and is mainly running in one-way mode. It is expensive to rebuild the CATV from one-way to two-way. Using Prefetch System, we can achieve the virtual Internet and virtual two-way comm...

We distinguish between three types of outliers in a one-way random e ects model. These are formally described in terms of their position relative to the main part of the observations. We propose simple rules for identifying such outliers and give an example which involves median-based statistics.

The present study investigates the determinants of intention to use carsharing services by an integrated model psychological predictors travel behavior. proposed is tested multigroup confirmatory factor analysis (MGCFA) in structural equation modeling (SEM) with further discussion about invariance and its relevance for comparisons between groups. sample was classified into four groups: Italian ...

For cities, it is cruicial to solve their mobility issues. One of the approaches is to convince people to use more sustainable means of transportation. This research investigates the effect of social influence and financial incentives in the state of “particular matter emergency” in Stuttgart, Germany. Preliminary results show an increased awareness, a reduction of cars on the road and increase...

In this work we give the first non-adaptive construction of universal one-way hash functions (UOWHFs) from arbitrary functions. Our uses $$O(n^9)$$ calls to function, has a key length $$O(n^{10})$$ , and can be implemented in NC1 assuming underlying function is NC1. Prior work, best UOWHF used $$O(n^{13})$$ adaptive size $$O(n^5)$$ (Haitner, Holenstein, Reingold, Vadhan Wee [Eurocrypt ’10]). By...

Free-floating carsharing is a young and rapidly expanding market that allows customers to end their rentals anywhere within the business area of the provider. Through this flexibility it complements public transportation and reduces the environmental footprint of the transportation sector. We present a novel data analytics methodology that supports companies – from local start-ups to global pla...

Global use of carsharing has increased. The dominant model is station-based carsharing, but free-floating providers are continuously increasing their businesses volumes. Carsharing customers have been described as environmentally conscious with a high preference for mobility who show responsibility and trustworthiness. This generalization usage determinants appears to be questionable given the ...
