SecureCells: A Secure Compartmentalized Architecture

Babak Falsafi, Mathias Josef Payer, Yuanlong Li, Andrés Sánchez Marín, Florian Hofhammer, Siddharth Gupta, Atri Bhattacharyya

Modern programs are monolithic, combining code of varied provenance without isolation, all the while running on network-connected devices. A vulnerability in any component may compromise code and data of all other components. Compartmentalization separates ...

H∞ and μ-Synthesis for Nanosatellites Rendezvous and Docking

Volker Gass, Camille Sébastien Pirat

In this brief, the nanosatellite rendezvous and docking problem is tackled. It was never attempted for small spacecraft, as critical technologies, such as six-degree-of-freedom (DoF) micropropulsion systems, have only recently become available due to advan ...

A mixed-signal computer architecture and its application to power system problems

Theodoros Kyriakidis

Radical changes are taking place in the landscape of modern power systems. This massive shift in the way the system is designed and operated has been termed the advent of the ``smart grid''. One of its implications is a strong market pull for faster power ...

Half-scale experimental study of rockfall impacts on sandy slopes

Vincent Labiouse, Barbara Heidenreich

In the framework of rockfall trajectory modelling, the bouncing phenomenon occurring when a rock block impacts with the slope surface is the most difficult to predict, owing to its complexity and its very limited understanding. To date, the rebound is comm ...
