BF-Tree: Approximate Tree Indexing

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis

The increasing volume of time-based generated data and the shift in storage technologies suggest that we might need to reconsider indexing. Several workloads - like social and service monitoring - often include attributes with implicit clustering because o ...

Approximate Probabilistic Tree Indexing for Partitionable Data

Anastasia Ailamaki, Manoussos Gavriil Athanassoulis

Today we experience a shift both in storage technologies and in workloads characteristics. Firstly, solid state disks (SSD) (using flash, PCM or other low-level technologies) emerge as viable competitors of hard disk drives (HDD). Secondly, the increasing ...

X-Stream: Edge-centric Graph Processing using Streaming Partitions

Willy Zwaenepoel, Amitabha Roy, Ivo Mihailovic

X-Stream is a system for processing both in-memory and out-of-core graphs on a single shared-memory machine. While retaining the scatter-gather programming model with state stored in the vertices, X-Stream is novel in (i) using an edge-centric rather than ...

Satisfiability of Elastic Demand in the Smart Grid

Jean-Yves Le Boudec, Dan-Cristian Tomozei

We study a stochastic model of electricity production and consumption where appliances are adaptive and adjust their consumption to the available production, by delaying their demand and possibly using batteries. The model incorporates production volatilit ...

A Metamodel of the Oil Game under Climate Treaties

Marc Vielle, Alain Haurie

A climate treaty like the one which should replace the Kyoto Protocol after 2012, may have important impacts on the oil, gas and coal markets. The full impact of such a treaty will not be felt before 2030. In this paper one uses a computable general equili ...
