Achieving High Freshness and Optimal Throughput in CPU-Limited Execution of Multi-join Continuous Queries
Due to high data volumes and unpredictable arrival rates, continuous query systems processing expensive queries in real-time may fail to keep up with the input data streams - resul...

Randomized computations on large data sets: tight lower bounds
We study the randomized version of a computation model (introduced in [9, 10]) that restricts random access to external memory and internal memory space. Essentially, this model c...

Reduced Epipolar Cost for Accelerated Incremental SfM
We propose a reduced algebraic cost based on pairwise epipolar constraints for the iterative refinement of a multiple view 3D reconstruction. The aim is to accelerate the intermedi...

Computing isochrones in multi-modal, schedule-based transport networks
Isochrones are defined as the set of all points from which a specific point of interest is reachable within a given time span. This demo paper presents a solution to compute isoch...
