Flexure-based pointing mechanism with sub-microradian resolution for the Laser Interferometer Space Antenna

The Point Ahead Angle Mechanism (PAAM) for ESA’s Laser Interferometer Space Antenna (LISA) mission will compensate the out-of-plane point-ahead angle between three satellites flying 5 million kilometres apart. The PAAM consists of a mirror supported by fle ...

Modélisation géométrique itérative sous contraintes

Gilles Gouaty

Iterative models are widely used today in CAD. They allow, with a limited number of parameters, to represent relatively complex forms through a subdivision algorithm. There is a wide variety of such models (Catmull-Clark, Doo-Sabin, L-Systems...). Most ite ...

Experimental investigation into the shear resistance of a reinforced UHPFRC web element

Eugen Brühwiler, Talayeh Noshiravani, Karl Telleen, Rita Galrito

Ultra-high performance fiber reinforced concrete (UHPFRC) can be implemented in combination with steel reinforcing bars to enhance the performance of UHPFRC elements subject to shear stresses. This paper presents an experimental investigation into the beha ...

Drawing Hamiltonian cycles with no large angles

János Pach

Let n >= 4 be even. It is shown that every set S of n points in the plane can be connected by a (possibly self-intersecting) spanning tour (Hamiltonian cycle) consisting of n straight-line edges such that the angle between any two consecutive edges is at m ...

Multicomponent wavefield characterization with a novel scanning laser interferometer

Thomas Emmanuel Blum

The in-plane component of the wavefield provides valuable information about media properties from seismology to nondestructive testing. A new compact scanning laser ultrasonic interferometer collects light scattered away from the angle of incidence to prov ...

Toe protection for spill-through and vertical-wall abutments

Anton Schleiss, António Heleno Cardoso

This study addresses the design of riprap aprons as a scour countermeasure near abutments under clear-water conditions. It deals with the lateral extent of riprap aprons and the geometry of the scour hole prevailing at the apron edge. The study applies to ...

Drift stabilization of ballooning modes in a high-$\langle \beta \rangle$ LHD configuration

Jonathan Graves, Wilfred Anthony Cooper, Lucie Brocher

Ideal MHD yields at best inconclusive predictions about the stability of the LHD heliotron for

\langle \beta \rangle \geq 3\%

. We investigate the impact of the drift stabilization of ballooning modes for the inward shifted LHD configuration (vacuum magne ...

Implications of thermal sensitivity of the static internal friction angle

Lyesse Laloui, Bertrand François

Thermal variability of the coefficient of the critical state, or the angle of internal friction is examined in view of experimental results obtained for clays and hard rocks. This sensitivity has several implications for the evolution of what is considered ...

Design and development of the point-ahead angle mechanism for the lase interferometer space antenna (LISA)

Simon Nessim Henein, Philippe Schwab

The Point Ahead Angle Mechanism (PAAM) for ESA’s Laser Interferometer Space Antenna (LISA) mission will compensate the out-of-plane point-ahead angle between three satellites flying 5 million kilometres apart. The PAAM consists of a mirror supported by fle ...

Tearing as a test for mechanical characterization of thin adhesive films

Pedro Miguel Nunes Pereira de Almeida Reis

Thin adhesive films have become increasingly important in applications involving packaging, coating or for advertising. Once a film is adhered to a substrate, flaps can be detached by tearing and peeling, but they narrow and collapse in pointy shapes. Simi ...
