CPT spectroscopy on low-temperature sealed MEMS rubidium vapour cells

Nico de Rooij, Herbert Shea, Thomas Maeder, Yves Pétremand, Frank Seigneur

In recent years there has been a strong effort to reduce the size and power consumption of vapour cell atomic clocks [1,2]. The progress in this direction is driven by several factors such as the use low power laser diodes (VCSEL), Coherent Population Trap ...

Intermediate view generation for perceived depth adjustment of stereo video

Zafer Arican

There is significant industry activity on delivery of 3D video to the home. It is expected that 3D capable devices will be able to provide consumers with the ability to adjust the depth perceived for stereo content. This paper provides an overview of relat ...

Phoneme Recognition Using Spectral Envelope and Modulation Frequency Features

Hynek Hermansky, Sriram Ganapathy, Samuel Thomas

We present a new feature extraction technique for phoneme recognition that uses short-term spectral envelope and modulation frequency features. These features are derived from sub-band temporal envelopes of speech estimated using Frequency Domain Linear Pr ...

99% random telegraph signal-like noise in gold nanoparticle mu-stripes

Jürgen Brugger

In this paper, we report on a process to prepare gold nanoparticle stripes on SiO2 by convective/capillary assembly without any patterning of the substrate. Electrical devices were then fabricated using stencil lithography in order to avoid any contaminati ...

Broadcast and Slepian-Wolf multicast over Aref Networks

Satish Babu Korada, Dinkar Vasudevan

We consider source coding over Aref networks. In particular we consider the following two problems: (i) multicasting correlated sources to a set of receivers, (ii) broadcasting sources to their respective receivers. For the first problem we show necessary ...

Efficient Broadcasting Using Network Coding

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We consider the problem of broadcasting in an ad-hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless netwo ...

Online Broadcasting with Network Coding

Christina Fragouli, Lorenzo Keller

Consider a source broadcasting M packets to N receivers over independent erasure channels, where perfect feedback is available from the receivers to the source, and the source is allowed to use coding. We investigate offline and online algorithms that opti ...

Microwave frequency modulation in continuous-wave far-infrared ESR utilizing a quasi-optical reflection bridge

László Forró, Richard Gaal, Bálint Náfrádi

We report the development of the frequency-modulation (FM) method for measuring electron spin resonance (ESR) absorption in the 210- to 420 GHz frequency range. We demonstrate that using a high-frequency ESR spectrometer without resonating microwave compon ...

Low-complexity Algorithms for Energy Efficient Broadcasting in Wireless Networks

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

We consider the problem of broadcasting in an ad hoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Our figure of merit is energy efficiency, a critical design parameter for wireless net- ...
