64.3L: Late‐News Paper: Aerial Imaging by Retro‐Reflection (AIRR)
SID Symposium Digest of Technical Papers, 2013Co-Authors: Hirotsugu Yamamoto, Shiro SuyamaAbstract:We propose a new method to realize aerial display that enables three-dimensionally floating transparent signage without Physical Hardware on the sign position. The proposed aerial imaging method is based on retro-reflection. An aerial image of the LED panel has been successfully formed with a mirror window and retro-reflective material.

Reliability of Computational Experiments on Virtualised Hardware
arXiv: Distributed Parallel and Cluster Computing, 2011Co-Authors: Ian P. Gent, Lars KotthoffAbstract:We present preliminary results of an investigation into the suitability of virtualised Hardware -- in particular clouds -- for running computational experiments. Our main concern was that the reported CPU time would not be reliable and reproducible. The results demonstrate that while this is true in cases where many virtual machines are running on the same Physical Hardware, there is no inherent variation introduced by using virtualised Hardware compared to non-virtualised Hardware.

CLOUD - A Replication Study to Explore Network-Based Co-residency of Virtual Machines in the Cloud
Lecture Notes in Computer Science, 2020Co-Authors: Sanchay Gupta, Robert Miceli, Joel CoffmanAbstract:By deploying virtual machines (VMs) on shared infrastructure in the cloud, users gain flexibility, increase scalability, and decrease their operational costs compared to on-premise infrastructure. However, a cloud environment introduces new vulnerabilities, particularly from untrusted users sharing the same Physical Hardware. In 2009, Ristenpart et al. demonstrated that an attacker could place a VM on the same Physical Hardware and extract confidential information from a target using a side-channel attack. We replicated this seminal work on cloud cartography and network-based co-residency tests on Amazon Web Services (AWS) and OpenStack cloud infrastructures. Although the Elastic Compute Cloud (EC2) cloud cartography remains similar to prior work, current mitigations deter the network-based co-residency tests. OpenStack’s cloud cartography differs from EC2’s, and we found that OpenStack was vulnerable to one network-based co-residency test. Our results indicate that co-residency threats remain a concern more than a decade after their initial description.

CLUSTER - Performance of a Virtual Cluster in a General-Purpose Teaching Laboratory
2011 IEEE International Conference on Cluster Computing, 2011Co-Authors: Eric Johnson, Patrick Garrity, Timothy Yates, Richard A. BrownAbstract:Through virtualization, a Beowulf cluster running on the Physical Hardware and network of a general purpose teaching laboratory can provide significant computational power without compromisingâ"in fact increasingâ"the educational value of the lab machines. After describing our implementation of such a virtual cluster in a teaching lab, we analyze its performance by comparing benchmark results to those of an equivalent dedicated (native) cluster and investigate expedient improvements to our design.
