Test and lower bound modeling of keyed shear connections in RC shear walls

Aurelio Muttoni, Cao Linh Hoang, Jesper Harrild Sorensen

This paper presents an investigation into the ultimate behavior of a recently developed design for keyed shear connections. The influence of the key depth on the failure mode and ductility of the connection has been studied by push-off tests. The tests sho ...

Low rank differential equations for Hamiltonian matrix nearness problems

Daniel Kressner

For a Hamiltonian matrix with purely imaginary eigenvalues, we aim to determine the nearest Hamiltonian matrix such that some or all eigenvalues leave the imaginary axis. Conversely, for a Hamiltonian matrix with all eigenvalues lying off the imaginary axi ...

Demodulation of time series highlights impacts of hydrologic drivers on the Everglades ecosystem

Andrea Rinaldo

In the context of climatic uncertainty and potential climatic change, incorporating climatic variability and change in eco-hydrological analysis, as well as understanding the impact of such variability on ecosystems, is of crucial importance. The latter is ...

The Stationary Behaviour of Fluid Limits of Reversible Processes is Concentrated on Stationary Points

Jean-Yves Le Boudec

Assume that a stochastic process can be approximated, when some scale parameter gets large, by a fluid limit (also called mean field limit", or hydrodynamic limit"). A common practice, often called the ``fixed point approximation" consists in approxima ...

Parametric inversion of spin currents in semiconductor microcavities

Hugo Pierre Alexandre Flayac

The optical spin-Hall effect results in the formation of an antisymmetric real-space polarization pattern giving birth to spin currents. In this work, we show that the exciton-polariton parametric scattering allows us to reverse the sign of these currents. ...

Non-Stationary Hydrologic Transport in the Vadose Zone: Experimental Results of Multiple Tracer Injections in Lysimeters

Andrea Rinaldo, Pierre Claude Jean Queloz

Travel and residence times are well-known descriptors of hydrologic and solute transport in the vadose zone. It has been observed that their probability density functions are stationary only under specific conditions, rarely encountered in natural catchmen ...

Application of Artificial Vision to the Quality Inspection of Surfaces of Luxury Products

Giuseppe Zamuner

This thesis defines a general approach for the automated visual inspection of surfaces of luxury products, the aesthetic quality of which represents a corollary to the technical mastery necessary to manufacture valuable products. Within a manufacturing ent ...

Determination of depolarization temperature of (Bi1/2Na1/2)TiO3-based lead-free piezoceramics

Dragan Damjanovic

The depolarization temperature T-d of piezoelectric materials is an important figure of merit for their application at elevated temperatures. Until now, there are several methods proposed in the literature to determine the depolarization temperature of pie ...

A natural-norm Successive Constraint Method for inf-sup lower bounds

Jan Sickmann Hesthaven, Yixing Chen

We present a new approach for the construction of lower bounds for the inf-sup stability constants required in a posteriori error analysis of reduced basis approximations to affinely parametrized partial differential equations. We combine the ``linearized' ...
