Metric Learning with Rank and Sparsity Constraints

Volkan Cevher, Baran Gözcü, Bubacarr Bah

Choosing a distance preserving measure or metric is fun- damental to many signal processing algorithms, such as k- means, nearest neighbor searches, hashing, and compressive sensing. In virtually all these applications, the efficiency of the signal process ...

Open-loop control of a separated boundary layer

François Gallaire, Edouard Boujo

Linear optimal gains

G_{opt}(\omega)

are computed for the separated boundary-layer flow past a two-dimensional bump in the subcritical regime. Very large values are found, making it possible for small-amplitude noise to be strongly amplified and to desta ...

Calculation of average coding efficiency based on subjective quality scores

Touradj Ebrahimi, Philippe Hanhart

The Bjøntegaard model is widely used to calculate the coding efficiency between different codecs. However, this model might not be an accurate predictor of the true coding efficiency as it relies on PSNR measurements. Therefore, in this paper, we propose a ...

Variational Justification of Cycle Spinning for Wavelet-Based Solutions of Inverse Problems

Michaël Unser, Emrah Bostan, Ulugbek Kamilov

Cycle spinning is a widely used approach for improving the performance of wavelet-based methods that solve linear inverse problems. Extensive numerical experiments have shown that it significantly improves the quality of the recovered signal without increa ...

Junctionless Silicon Nanowire Resonator

Mihai Adrian Ionescu, Sebastian Thimotee Bartsch, Maren Arp

The development of nanoelectromechanical systems (NEMS) is likely to open up a broad spectrum of applications in science and technology. In this study, we demonstrate a novel double-transduction principle for silicon nanowire resonators which exploits the ...

Comparison of an 8-Channel and a 32-Channel Coil for High-Resolution fMRI at 7 T

Wietske Van der Zwaag, Roy Salomon, Mayur Narsude, Jana Darulová

Multi-channel receive array rf-coils have become widely available for fMRI. The improved SNR and possibility of acquisition acceleration through parallel imaging are especially beneficial for high-resolution studies. In this study, an 8-channel and a 32-ch ...

Multi-level wordline driver for robust SRAM design in nano-scale CMOS technology

Georgios Karakonstantis

In this paper, a multi-level wordline driver scheme is presented to improve 6T-SRAM read and write stability. The proposed wordline driver generates a shaped pulse during the read mode and a boosted wordline during the write mode. During read, the shaped p ...

A simple relaying strategy for diamond networks

Christina Fragouli, Siddhartha Brahma

We consider a Gaussian diamond network where a source communicates with the destination through n non-interfering half-duplex relays. Using simple approximations to the capacity of the network, we show that simple relaying strategies involving two relays a ...
