چکیده

TripBuilder is an unsupervised system helping tourists to build their own personalized sightseeing tour [1, 3, 2]. Given a target touristic city, the time available for the visit, and the tourist’s profile, TripBuilder provides a time-budgeted tour that maximizes tourist’s interests and takes into account both the time needed to enjoy the attractions and to move from one Point of Interest (PoI) to the next one. The knowledge base feeding the sightseeing tour generation algorithm of TripBuilder is entirely mined from publicly available sources, namely, Wikipedia, Flickr and Google Maps. This paper introduces a scalable and robust Cloud architecture (combining both stream and batch processing) to download the data from the heterogeneous sources and build a huge TripBuilder knowledge base covering most popular cities worldwide.

A new 2D block ordering system for wavelet-based multi-resolution up-scaling

A complete and accurate analysis of the complex spatial structure of heterogeneous hydrocarbon reservoirs requires detailed geological models, i.e. fine resolution models. Due to the high computational cost of simulating such models, single resolution up-scaling techniques are commonly used to reduce the volume of the simulated models at the expense of losing the precision. Several multi-scale ...

Global Surgery – Redirecting Strategies for a Global Research Agenda; Comment on “Global Surgery – Informing National Strategies for Scaling Up Surgery in Sub-Saharan Africa”

More than three years have passed since the publication of the Lancet Commission on Global Surgery and its recommendations on scaling up surgery in sub-Saharan Africa (SSA). An important gap, the voice of the districts as well as lack of contextualized research, has been noted in its support of national surgical plans that run the risk of being at best, aspirational. Moreover, a ‘one-size-fits-...
