Composition of the low seismic velocity E ′ layer at the top of Earth's core

James Badro

Using ab initio simulations on Fe-Ni-S-C-O-Si liquids, we constrain the origin and composition of the low-velocity layer E′ at the top of Earth's outer core. We find that increasing the concentration of any light element always increases velocity and so a ...

A deployable tensegrity footbridge that connects at mid-span

Ian Smith, Nicolas Willy Veuve, Seif Dalil Safaei

This paper describes a near full-scale deployable tensegrity footbridge that deploys from both sides and connects at mid-span. Tensegrity structures are pre-stressed structures composed of tension elements (cables) surrounded by compression elements (strut ...

Semiclassical evidence of columnar order in the fully frustrated transverse-field Ising model on the square lattice

Frédéric Mila, Tommaso Coletta

We investigate the zero-temperature phase diagram of the fully frustrated transverse-field Ising model on the square lattice both in the classical limit and in the presence of quantum fluctuations. At the classical level (the limit of infinite spin S), we ...

Ka-Band Rectangular Waveguide to Suspended Stripline Transition

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

A Ka-band transition between a rectangular waveguide and a suspended stripline (SSL) is proposed. It uses a configuration in which the SSL substrate is perpendicular to the waveguide main axis. A patch printed on the SSL substrate is used to match the char ...

A Low-Loss Planar Ka-Band Antenna Subarray for Space Applications

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

This paper presents the design, optimization, and experimental characterization of a planar antenna subarray for space applications. The proposed component is intended to be used as a building block for a large Ka-band antenna systems. It is a one-dimensio ...

Revisiting Goal-Oriented Requirements Engineering with a Regulation View

Gil Regev, Alain Wegmann

Goal-Oriented Requirements Engineering (GORE) is considered to be one of the main achievements that the Requirements Engineering field has produced since its inception. Several GORE methods were designed in the last twenty years in both research and indust ...

Dynamic fragmentation of a ring: Predictable fragment mass distributions

Jean-François Molinari, Anthony Christopher Davison, Sarah Levy, Irene Vicari

We employ a finite element framework, coupled to cohesive elements, to model material decohesion of a uniformly expanding ring. Our study focuses on the average fragment mass, the distribution of fragment masses, and the heaviest fragments. The computed fr ...
