Analyzing and Protecting Communication Metadata

Most communication systems (e.g., e-mails, instant messengers, VPNs) use encryption to prevent third parties from learning sensitive information.However, encrypted communications protect the contents but often leak metadata: the amount of data sent and the ...

Adaptive partitioning and indexing for in situ query processing

Anastasia Ailamaki, Manolis Karpathiotakis, Ioannis Alagiannis, Manoussos Gavriil Athanassoulis, Matthaios Alexandros Olma

The constant flux of data and queries alike has been pushing the boundaries of data analysis systems. The increasing size of raw data files has made data loading an expensive operation that delays the data-to-insight time. To alleviate the loading cost, in ...

Optimal Distribution of Active Modules in Modular Robots

Jamie Paik, Christoph Heinrich Belke, Meibao Yao

Reconfigurability in versatile systems of modular robots is achieved by appropriate actuation of their modular units. Optimized distribution of active modules in the modular architecture can significantly reduce cost and energy in the reconfiguration tasks ...

Towards Peak Torque Minimization for Modular Self-folding Robots

Jamie Paik, Christoph Heinrich Belke, Meibao Yao

Modular self-folding robots are versatile systems that can change their own shape from two-dimensional patterns at instant commands. This reconfigurability is commonly restrained by power limitation in autonomous environments. The robotic systems with insu ...

How CSMA/CA With Deferral Affects Performance and Dynamics in Power-Line Communications

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

Power-line communications (PLC) are becoming a key component in home networking, because they provide easy and high-throughput connectivity. The dominant MAC protocol for high data-rate PLC, the IEEE 1901, employs a CSMA/CA mechanism similar to the backoff ...

Method and System for Fault Detection and Faulted Line Identification in Power Systems using Synchrophasors-Based Real-Time State Estimation

Mario Paolone, Paolo Romano, Marco Pignati, Lorenzo Zanni

A method for a faulted line identification in a power network, including, at a generic time-instant, solving a plurality of parallel phasor measurement units based real-time state estimators, the state estimators having among each other different and augme ...

On the MAC for Power-Line Communications: Modeling Assumptions and Performance Tradeoffs

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

Power-line communications are becoming a key component in home networking. The dominant MAC protocol for high data-rate power-line communications, IEEE 1901, employs a CSMA/CA mechanism similar to the backoff process of 802.11. Existing performance evaluat ...

Efficient Testing of Recovery Code Using Fault Injection

George Candea, Paul Dan Marinescu

A critical part of developing a reliable software system is testing its recovery code. This code is traditionally difficult to test in the lab, and, in the field, it rarely gets to run; yet, when it does run, it must execute flawlessly in order to recover ...
