An accurate and coherent chronological framework is essential for the interpretation of climatic and environmental records obtained from deep polar ice cores. Until now, one common ice core age scale had been developed based on an inverse dating method (Da ...
The Arctic Yearbook is the outcome of the Northern Research Forum and the University of the Arctic Thematic Network (TN) on Geopolitics and Security. The TN also organizes the annual Calotte Academy. The Arctic Yearbook is intended to be the preeminent rep ...
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 ...
We analyze the internal permutations of Keccak, one of the NIST SHA-3 competition finalists, in regard to differential properties. By carefully studying the elements composing those permutations, we are able to derive most of the best known differential pa ...
It is notoriously difficult to develop reliable, high-performance distributed systems that run over asynchronous networks. Even if a distributed system is based on a well-understood distributed algorithm, its implementation can contain errors arising from ...
The MetallicArt technique is used as a visual security feature to hide patterns in CMY images using an additional silver ink. The patterns are hidden under nonspecular viewing conditions and visible under specular viewing conditions. By varying the amount ...
Gossip, also known as epidemic dissemination, is becoming an in- creasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural ex- tension of the random phone-call ...
Thorough testing of software systems requires ways to productively employ fault injection. We describe a technique for automatically identifying the errors exposed by shared libraries, finding good injection targets in program binaries, and producing corre ...
This work shows how to develop distributed versions of block blind estimation techniques that have been proposed before for batch processing. Using diffusion adaptation techniques, data are accumulated at the nodes to form estimates of the auto-correlation ...
The overall goal is the development of a new control software for the inertial wheel assembly of the SwissCube project. SwissCube is an educational project of several Swiss universities and technical colleges under the supervision of the Space Center of EP ...
