Aegis: A Single-Chip Secure Processor [PDF]

IEEE Design & Test of Computers, 2005
In this article, we introduce a single-chip secure processor called Aegis. In addition to supporting mechanisms to authenticate the platform and software, our processor incorporates mechanisms to protect the integrity and privacy of applications from physical attacks as well as software attacks.

Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

PLANTS, PEOPLE, PLANET, EarlyView.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

Innovative Strategies and Use of UAVs to Survey and Monitor Archaeological Sites in Conflict/Post Conflict Zones. The Case Study of the Fortified Citadel of Shahr-i Zohak in Bamiyan (Afghanistan) [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Although unmanned aerial vehicle (UAV) mapping and photogrammetry have become common and relatively accessible for surveying and mapping cultural heritage sites, conducting surveys to model sites in conflict/post conflict zones remains challenging.

Observational constraints on the physics behind the evolution of AGN since z ~ 1

, 2011
We explore the evolution with redshift of the rest-frame colours and space densities of AGN hosts (relative to normal galaxies) to shed light on the dominant mechanism that triggers accretion onto supermassive black holes as a function of cosmic time ...

Analysis of a Custom Support Vector Machine for Photometric Redshift Estimation and the Inclusion of Galaxy Shape Information [PDF]

, 2017
Aims: We present a custom support vector machine classification package for photometric redshift estimation, including comparisons with other methods. We also explore the efficacy of including galaxy shape information in redshift estimation.

The AEgIS experiment

Hyperfine Interactions, 2015
The AEgIS experiment is presently almost completely installed at CERN. It is currently taking data with antiprotons, electrons and positrons. The apparatus is designed to form a cold, pulsed beam of antihydrogen to measure the Earth’s gravitational acceleration g on antimatter and to perform spectroscopy measurements.

AEGIS [PDF]

Proceedings of the 2018 Workshop on Security in Softwarized Networks: Prospects and Challenges, 2018
An important consideration in Software-defined Networks (SDNs), is that one SDN application, through a bug or API misuse, can break an entire SDN. While previous works have tried to mitigate such concerns by implementing access control mechanisms (permission models) for an SDN controller, they commonly require serious manual efforts in creating a ...

Unlocking Energy Potential: Exploiting Anionic Redox Activity in Na‐Based Layered Oxides

Small, EarlyView.
Anionic redox in Na‐based layered oxide cathodes unlocks additional capacity beyond conventional transition‐metal redox limits, enabling high‐energy sodium‐ion batteries. This review elucidates coupled cationicanionic redox mechanisms across P2‐, O3‐, and related structural phases, while critically addressing key challenges such as voltage hysteresis ...

AEgIS experiment commissioning at CERN [PDF]

AIP Conference Proceedings, 2013
The AEgIS Experiment is an international collaboration based at CERN whose aim is to perform the first direct measurement of the gravitational acceleration g of antihydrogen in the gravitational field of the Earth. Cold antihydrogen will be produced with a pulsed charge exchange reaction in a cylindrical Penning trap where antiprotons will be cooled to
