Finite-temperature flexoelectricity in ferroelectric thin films from first principles

A first-principles-based effective Hamiltonian technique is developed to study flexoelectricity in (Ba0.5Sr0.5)TiO3 thin films of different thicknesses in their paraelectric phase. The magnitude as well as sign of individual components of the flexoelectric ...

Post-fabrication control of evanescent tunnelling in photonic crystal molecules

Laurent Balet, Massimo Gurioli

The post-fabrication control of evanescent tunnelling in photonic crystal molecules is demonstrated through the combination of selective infiltration and oxidation. By laser non thermal oxidation, we reduce the photonic coupling by more than 30% while by m ...

Punching shear strength of R/C slabs subjected to fire

Aurelio Muttoni, Miguel Fernández Ruiz

This paper illustrates a study on the punching shear strength of reinforced concrete slabs in fire conditions. To this end, a set of experimental data on the punching strength of heated slab specimens was interpreted by adapting the well-known Critical She ...

Polarization mode structure in long-wavelength wafer-fused vertical-cavity surface-emitting lasers

Elyahou Kapon, Grigore Suruceanu, Nicolas Volet, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

Applications of long-wavelength (lambda > 1 mu m) vertical-cavity surface-emitting lasers (VCSELs) generally require close control over wavelength and polarization of the emitted light. In most cases, single mode and polarization stable lasing is desired. ...

Evaluation of servo, geometric and dynamic error sources on five-axis high-speed machine tool

Loïc Andolfatto

Many sources of errors exist in the manufacturing process of complex shapes. Some approximations occur at each step from the design geometry to the machined part. The aim of the paper is to present a method to evaluate the effect of high-speed and high dyn ...

Adaptive Monte Carlo applied to uncertainty estimation in five axis machine tool link errors identification with thermal disturbance

Loïc Andolfatto

Knowledge of a machine tool axis to axis geometric location errors allows compensation and corrective actions to be taken to enhance its volumetric accuracy. Several procedures exist, involving either lengthy individual test for each geometric error or fas ...

Optimal selection of cutting parameters in multi-tool milling operations using a genetic algorithm

Paul Xirouchakis, Jitender Kumar Rai, Mohammed Slama, Daniel Brand

In the milling of large monolithic structural components for aircraft, 70-80% of the total cut volume is removed using high-speed roughing operations. In order to achieve the economic objective (i.e. optimal part quality in minimal machining time) of this ...
