Laser gyroscopes making use of the Sagnac effect have been used as highly accurate rotation sensors for many years. First used in aerospace and defense applications, these devices have more recently been used for precision seismology and in other research settings. In particular, mid-sized (∼ 1 m-scale) laser gyros have been under development as tilt sensors to augment the adaptive active seism...

Quantum key distribution is the most advanced technology to arise from the emerging field of quantum information. In fact, a few companies (MaqiQ Technologies and id Quantique) already offer commercial quantum key distribution products. But why so much excitement over QKD when our standard techniques serve just fine? Well the thing is that our standard techniques are safe only under certain ass...

Natural enemies often cause significant levels of mortality for their prey and thus can be important agents of natural selection. It follows, then, that selection should favor traits that enable organisms to escape from their natural enemies into "enemy-free space" (EFS). Natural selection for EFS was originally proposed as a general force in structuring ecological communities, but more recentl...

The aim of this paper is to explain the relationship between the (co)homology of the free loop space and the Hochschild homology of its singular cochain algebra. We introduce all the relevant technical tools, namely simplicial and cyclic objects, and we provide the various steps of the proofs, which are scattered around in the literature. This paper can be seen as a companion to the paper “Cycl...

Image-space free-viewpoint video (FVV) is a framework for representation and coding of sparse multi-view video and subsequent re-rendering from arbitrary viewpoints. It is based on the fundamental concept of storing all information describing a scene’s visual appearance in multi-channel video images. Each pixel’s channels define different attributes of discrete point samples of observed surface...

Chatoyant is an opto-electro-mechanical CAD tool developed to meet the needs of systems designers. In this paper, we present the modeling techniques we have implemented in Chatoyant for system level design of mixed technology micro-systems along with simulation results. ©2000 Optical Society of America OCIS Codes: (200.0200) Optical computing, (060.0060) Fiber optics and optical communications

Nowadays there are different kinds of attacks on Field Programmable Gate Array (FPGA). As FPGAs are used in many different applications, its security becomes an important concern, especially in Internet of Things (IoT) applications. Hardware Trojan Horse (HTH) insertion is one of the major security threats that can be implemented in unused space of the FPGA. This unused space is unavoidable to ...
