Achieving Linear Scaling with Interference Alignment

Recent results have shown that interference alignment can achieve K/2 degrees of freedom in a K-user interference channel with time or frequency varying channel coefficients. For fixed number of users K, the number of degrees of freedom characterizes the a ...

Analysis of the blurring in stencil lithography

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Philippe Langlet, Oscar Vazquez Mena, Katrin Sidler Arnet

A quantitative analysis of the blurring and its dependence on the stencil-substrate gap and the deposition parameters in stencil lithography, a high resolution shadow mask technique, is presented. The blurring is manifested in two ways: first, the structur ...

Improved estimation of travel demand from traffic counts based on a new linearization of the network loading map

Michel Bierlaire, Gunnar Flötteröd

In the context of OD matrix estimation from traffic counts, we propose a new linearization of the network loading map that is superior to the usual proportional assignment in congested conditions. ...

Exploitation of iron B-H local hysteresis for the rotor position detection of a PM motor

Yves Perriard, Miroslav Markovic, Omar Scaglione

In this paper it is shown that the phase self inductance and resistance, both measured at a high frequency, of a permanent magnet (PM) motor with non-salient rotor vary slightly with the rotor position. The origin of these variations is deeply investigated ...

Cryptanalysis of an E0-like Combiner with Memory

Serge Vaudenay, Yi Lu

In this paper, we study an E0-like combiner with memory as the keystream generator. First, we formulate a systematic and simple method to compute correlations of the FSM output sequences (up to certain bits). An upper bound of the correlations is given, wh ...

Comparison of three commercially available radio frequency coils for human brain imaging at 3 Tesla

Rolf Gruetter, Wietske Van der Zwaag, Andreas Joosten

Objective To evaluate a transverse electromagnetic (TEM), a circularly polarized (CP) (birdcage), and a 12-channel phased array head coil at the clinical field strength of B (0) = 3T in terms of signal-to-noise ratio (SNR), signal homogeneity, and maps of ...

Roll waves in floods on inclines

The unstable nature of kinematic waves, resulting from outburst floods on steep inclines, is investigated theoretically using the shallow water equations. A numerical experiment is designed in order to efficiently perform a stability analysis. By analysing ...

Wide tuning range linearity improved biquadratic transconductor-C filter

Seyed Armin Tajalli, Yusuf Leblebici

This article presents a new technique for improving the linearity performance in biquadratic transconductor-C filters. This improvement has been achieved by applying some modifications to the filter topology which considerably relaxes the linearity require ...

Fluxgate-type magnetic microsensors for wide linear measuring range

Radivoje Popovic, Pavel Kejik, Ozge Zorlu

In this paper, we present a microfabricated fluxgate sensor for wide linear measuring range applications. The sensor consists of an electroplated copper excitation rod surrounded by an electroplated Permalloy core layer, and has planar pick-up coils for si ...

Thermal Effects on Physico-Mechanical Properties of Ultra-High-Performance Fiber-Reinforced Concrete

Eugen Brühwiler, Emmanuel Denarié, Aicha Kamen

Material characterization tests of an Ultra High Performance Fiber Reinforced Concrete (UHPFRC) were performed at various ages. A linear relationship was obtained between the mechanical properties and the degree of hydration. In parallel, the influence of ...
