Evaluating Resilience of Electricity Distribution Networks via A Modification of Generalized Benders Decomposition Method

, 2020
This paper presents a computational approach to evaluate the resilience of electricity Distribution Networks (DNs) to cyber-physical failures. In our model, we consider an attacker who targets multiple DN components to maximize the loss of the DN ...

Forecasting the cost of processing multi-join queries via hashing for main-memory databases (Extended version)

, 2015
Database management systems (DBMSs) carefully optimize complex multi-join queries to avoid expensive disk I/O. As servers today feature tens or hundreds of gigabytes of RAM, a significant fraction of many analytic databases becomes memory-resident.
