Galaxy Zoo: A catalog of overlapping galaxy pairs
(2013)Analysis of galaxies with overlapping images offers a direct way to probe the distribution of dust extinction and its effects on the background light. We present a catalog of 1990 such galaxy pairs selected from the Sloan Digital Sky Survey (SDSS) by volunteers of the Galaxy Zoo project. We highlight subsamples which are particularly useful for retrieving such properties of the dust distribution as UV extinction, the extent perpendicular ...Data Collection -
The UbiDCC Data Set
(2013)This is a data set resulted from a large-scale Data Collection Campaign (DCC). It took place during the UbiComp/ISWC 2013 conference at the ETH Zurich. Over 700 attendees were registered for this 3-days event. The UbiDCC data set contains (1) mobility traces of nearly 1200 devices at the venue extracted by processing the collected raw data, (2) Bluetooth and Wi-Fi raw data of 37 active participants, and (3) their demographic data. In the ...Dataset -
Reputation Formation and the Evolution of Cooperation in Anonymous Online Markets
(2013)Theoretical propositions stressing the importance of trust, reciprocity, and reputation for cooperation in social exchange relations are deeply rooted in classical sociological thought. Thoday's online markets provide a unique opportunity to test these theories using unobtrusive data. Our study investigates the mechanisms promoting cooperation in an online-auction market where most transactions can be conceived as one-time-only exchanges. ...Dataset -

Location choice of firms with special emphasis on spatial accessibility
(2013)Travel Survey Metadata SeriesLand use models play a decisive role in different domains: they allow estimating demographic trends for a given region, they enable comparisons between spatially relevant projects of public authorities, they facilitate dimensioning of public infrastructure, and they help to answer various other questions regarding possible future development of our built environment. Due to the tight interdependence between resident population (e.g. as ...Other Research Data -
Carrier or mode?
(2013)Travel Survey Metadata SeriesWhat choice alternatives do shippers actually have when shipping their products to a customer: do they choose among a number of transport solutions offered to them by transport service providers with certain service characteristics, or is it a choice between physical transport modes (e.g. road, rail, intermodal transport etc.)? These questions arise regularly in freight demand modelling, when Stated Preference (SP) experiments are carried ...Other Research Data -

SP-Befragung 2010 zum Verkehrsverhalten im Personenverkehr
(2013)Travel Survey Metadata SeriesStated Preference (SP) Befragungen werden in der Schweiz seit rund 10 Jahren zur Schätzung diskreter Entscheidungsmodelle zur Verkehrsmittel- und Routenwahl eingesetzt. Dabei waren oft spezielle Untersuchungszwecke massgebend, wie z.B. die Einführung der ICN-Züge oder die Prüfung des Mobility Pricings, die alle Fahrten mit langen Fahrtweiten untersuchten. SP- Befragungen sind insbesondere dann erfolgversprechend, wenn sie auf real berichteten ...Other Research Data -
Carpooling stated preference (SP)
(2013)Travel Survey Metadata SeriesA recent study aimed to estimate the potential of carpooling in Switzerland. Part of this study was a survey in which the attitude of the public towards this transport option was investigated using both multi-response questions and stated preference (SP) experiments. In order to gain an insight on how innovative modes are perceived in general, the SP part was composed of two different experiments, one of them including carsharing as ...Other Research Data -
