Optimal Number of Paths with Multipath Routing in Hybrid Networks

Patrick Thiran, Sébastien Christophe Henri

In recent years, multipath routing, i.e., employing several paths simultaneously, has emerged as an efficient way to provide significant throughput gains in local networks. This has been observed both with technologies that are not subject to interference, ...

Flow monitoring of particle-laden flows combining ultrasonic doppler and echo intensity profiling techniques

Giovanni De Cesare, Shun Nomura, Jumpei Hitomi

The methodology to reveal inner structures of turbidity currents are required. Their behaviors have important roles to affect the sedimentation or transportation of fine particles. We have proposed a novel monitoring methodology for flows containing fine p ...

On Simple Scattering and Diffraction Models using Point Cloud Maps for Channel Model or Coverage Predictions

Karol Jacek Kruzelecki, Jean-Frédéric Wagen

One of the several challenges for high capacity wireless communications is to find propagation models able to predict as easily and accurately as possible the propagation channel to assess the performance of wide-band wireless systems. An investigation of ...

A Physical Model of Non-stationary Blur in Ultrasound Imaging

Jean-Philippe Thiran, Yves Wiaux, Paul Hurley, Dimitris Perdios, Matthieu Martin Jean-André Simeoni, Marcel Arditi, Adrien Georges Jean Besson

Conventional ultrasound (US) imaging relies on delay-and-sum (DAS) beamforming which retrieves a radio- frequency (RF) image, a blurred estimate of the tissue reflectivity function (TRF). Despite the non-stationarity of the blur induced by propagation effe ...

Nonreciprocal reconfigurable microwave optomechanical circuit

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth, Marie Adrienne Ioannou, Akshay Koottandavida

Nonreciprocal devices, such as isolators, are required to protect sensitive superconducting quantum circuits. Growing research has focused on integrated alternatives to the existing bulky ferrite technologies. Here we realize a nonreciprocal isolator with ...

LMA Observation of Upward Flashes at Santis Tower: Preliminary Results

Marcos Rubinstein, Mohammad Azadifar, Amirhossein Mostajabi

Lightning striking tall towers is mainly of the upward lightning type, which is characterized by the absence of a first return stroke and the presence of an initial continuous current (ICC) with or without superimposed pulses. The Santis Tower is 124 m tal ...

Demographic stochasticity and resource autocorrelation control biological invasions in heterogeneous landscapes

Andrea Rinaldo, Andrea Giometto, Florian Altermatt

Mounting theoretical evidence suggests that demographic stochasticity, environmental heterogeneity and biased movement of organisms individually affect the dynamics of biological invasions and range expansions. Studies of species spread in heterogeneous la ...

Experimental investigation of the propagation properties of Bloch surface waves on dielectric multilayer platform

Hans Peter Herzig, Elsie Barakat, Richa Dubey

Background: The periodic dielectric multilayers sustaining Bloch surface waves have been proposed as a platformfor the sensing applications and the two dimensional integrated optics. In this paper, we present the experimental and theoretical investigation ...

A Time-Division Multiplexing Signaling Scheme for Low-Power Multi-Drop Memory Links

Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust, Chen Cao

A time-division multiplexing (TDM) digital channel coding scheme for wireline multi-drop interfaces has been proposed. Shaping the TX spectrum to avoid channel frequency notches, the proposed digital TDM signaling reduces inter-symbol interference (ISI) an ...
