Representing complex urban geometries in mesoscale modeling

Darren Robinson, Alain Clappier, Adil Rasheed

Real cities are comprised of a diverse, random arrangement of building positions, shapes, and sizes. Yet most of the urban parameterisations thus far developed share the assumption that a city is made up of either a regular array of parallelepipeds or infi ...

Tandem collimators for the JET tangential gamma-ray spectrometer

Patrick Blanchard

The tangential gamma-ray spectrometer (TGRS) of the JET tokamak fusion facility is an important diagnostics for investigating the fast particle evolution. A well defined field of view for the TGRS diagnostics is essential for its proper operation and this ...

Free Form Deformation Techniques for 3D Shape Optimization Problems

Anwar Koshakji

The purpose of this work is to analyse and study an efficient parametrization technique for a 3D shape optimization problem. After a brief review of the techniques and approaches already available in literature, we choose to use the Free Form Deformation p ...

Tools and Frameworks for Big Learning in Scala: Leveraging the Language for High Productivity and Performance

Martin Odersky, Philipp Haller

Implementing machine learning algorithms for large data, such as the Web graph and social networks, is challenging. Even though much research has focused on making sequential algorithms more scalable, their running times continue to be prohibitively long. ...

Charge Collection Studies and Electrical Measurements of Heavily Irradiated 3D Double-Sided Sensors and Comparison to Planar Strip Detectors

Barinjaka Rakotomiaramanana

Three-dimensional (3D) silicon detectors offer advantages over standard planar devices as more radiation hard sensors. These detectors and their applications in the upgrades of the LHC experiments are discussed. 3D detectors with a double-sided geometry ha ...

Control of axisymmetric vortex breakdown in a constricted pipe: Nonlinear steady states and weakly nonlinear asymptotic expansions

François Gallaire, Philippe Meliga

The present paper investigates numerically and theoretically the axisymmetric vortex breakdown occurring in a constricted pipe of infinite extension, i.e., the transition from a smooth columnar state to a breakdown state exhibiting a recirculation bubble. ...

Polysilicon Nanowire Transistors and Arrays Fabricated With the Multispacer Technique

Giovanni De Micheli, Yusuf Leblebici, Mohamed Haykel Ben Jamaa

In this paper, we demonstrate the ability of the multi- spacer patterning technique to yield layers of polycrystalline silicon nanowires with a sublithographic pitch, by exclusively using micrometer resolution and CMOS processing steps. We characterize sin ...

Fine Sediment release from a reservoir by controlled hydrodynamic mixing

Anton Schleiss, Giovanni De Cesare, Jolanda Maria Isabella Jenzer Althaus

Reservoir sedimentation is worldwide a problem and requires a sustainable solution. The idea of maintaining sediment in suspension by a jet induced artificial turbulence and releasing it through the water intake was tested in laboratory experiments. Theref ...

Making a Reconfigurable Artificial Crystal by Ordering Bistable Magnetic Nanowires

Dirk Grundler

Spin-wave excitations (magnons) are investigated in a one-dimensional (1D) magnonic crystal fabricated out of Ni80Fe20 nanowires. We find two different magnon band structures depending on the magnetic ordering of neighboring wires, i.e., parallel and antip ...

State-resolved reactivity of CH4 on Pt(110)-(1 x 2): The role of surface orientation and impact site

Rainer Beck, Régis Bisson, Marco Sacchi

The reactivity of methane (CH4) on Pt(110)-(1×2) has been studied by quantum state-resolved surface reactivity measurements. Ground state reaction probabilities, S0(v=0) ~ S0(laser-off), as well as state-resolved reaction probabilities S0(2v3), for CH4 exc ...
