Jaeyoung Kwak, Hang-Hyun Jo, Tapio Luttinen, Iisakki Kosonen, Frederic Amblard
2015 PLoS ONE  
The findings from this study can be understood in the context of the pedestrian facility management, for instance, for retail stores.  ...  Walking is a fundamental activity of our daily life not only for moving to other places but also for interacting with surrounding environment.  ...  For large s, the joining probability is more likely to be influenced by the number of people who have already joined the attraction rather than the number of people not joining the attraction.  ...

It is associated with Idun, goddess of Spring, and with fertility. It is the phonetic equivalent of "b."  ...  Runes have angular shapes and lack horizontal lines because the primary storage medium was wood, although they may also be found on jewelry, tools, and weapons.  ...  Hence, we expect to find longer frequent routes, only if there are a large number of objects on the road network at the same time.  ...

Efficient Temporal Reasoning on Streams of Events with DOTR [chapter]

Alessandro Margara, Gianpaolo Cugola, Dario Collavini, Daniele Dell'Aglio
2018 Lecture Notes in Computer Science  
We implement the model in the DOTR system that defines ontological reasoning using Datalog rules and temporal reasoning using the TESLA Complex Event Processing language, which builds on metric temporal  ...  Many ICT applications need to make sense of large volumes of streaming data to detect situations of interest and enable timely reactions.  ...  To further improve these numbers, we move from the observation that query processing represents a large fraction of the entire processing time of DOTR, and we modify DOTR to move the data filtering process  ...

A new approach to scalable Linda-systems based on swarms

Ronaldo Menezes, Robert Tolksdorf
2003 Proceedings of the 2003 ACM symposium on Applied computing - SAC '03  
SCALABILITY OF LINDA SYSTEMS Scalability is today the sine qua non of efficient distributed systems. It is not uncommon for distributed systems to make use of a large number of active entities.  ...  In fact, we can foresee an increase on the number of active entities in the future and consequently an increase of communication in these systems.  ...  For instance, when searching for a tuple the individuals are the active templates that move on the grid of servers looking for tuples.  ...
