Amplifying Dynamic Nuclear Polarization of Frozen Solutions by Incorporating Dielectric Particles

David Lyndon Emsley, Aaron James Rossini, Dominik Józef Kubicki

There is currently great interest in understanding the limits on NMR signal enhancements provided by dynamic nuclear polarization (DNP), and in particular if the theoretical maximum enhancements can be achieved. We show that over a 2-fold improvement in cr ...

Content Management in Mobile Wireless Networks

Francisco De Meneses Neves Ramos Dos Santos

Approximately one billion users have access to mobile broadband, through which they intend to obtain the same data they can reach using a wired connection. Because of the cost of transmitting data over a mobile-broadband connection and given that 3G networ ...

Energy Efficient Offloading of 3G Networks

Jean-Yves Le Boudec, Nikodin Ristanovic

A huge increase in the amount of data consumed by smartphone users is becoming a serious problem for mobile operators. In three years, mobile data traffic in the AT&T's network rose 5000%. The US operators invest 50 billion dollars in their data networks e ...

A 1.5g SMA-actuated Microglider looking for the Light

Dario Floreano, André Guignard, Mirko Kovac, Jean-Daniel Nicoud, Jean-Christophe Zufferey

Unpowered flight can be used in microrobotics to overcome ground obstacles and to increase the traveling distance per energy unit. In order to explore the potential of goal-directed gliding in the domain of miniature robotics, we developed a 22cm microglid ...

Privacy Enabling Technology for Video Surveillance

Touradj Ebrahimi, Frédéric Dufaux, Mourad Ouaret, Yousri Abdeljaoued

In this paper, we address the problem privacy in video surveillance. We propose an efficient solution based on transform-domain scrambling of regions of interest in a video sequence. More specifically, the sign of selected transform coefficients is flipped ...
