Concrete tie model for the flexural behavior of RC and PC sections

The enhanced concrete tie model described in this paper can be used to determine the flexural behavior of RC and PC sections. This model is applicable to any concrete section, without shape restriction and will be implemented in a shell FE package. To evaluate the performance of the proposed model, a simple program has been developed, using a discretization of the cross section in slices

Structural properties of Ge/Si(001) nano-islands by diffraction anomalous fine structure and multiwavelength anomalous diffraction

8 pags, 6 figs, 2 tabsIn the present paper, we aim to show the interest of combining Multiwavelength Anomalous Diffraction (MAD) and Diffraction Anomalous Fine Structure (DAFS) spectroscopy, in grazing incidence, to obtain structural properties (composition, strain and atomic ordering) of semiconductor heterostructures and nanostructures. As an example we report on preliminary results obtained on a series of Ge/Si(001) nano-island samples: pyramides and domes on nominal and prepatterned surfaces. For free standing domes, it is shown that the Ge content strongly depends on the growth condition with a tendency to increase from the bottom to the top of the nano-islands. There is also some indication of atomic ordering in the upper part of the islands. For small, capped pyramids, we show that the Diffraction Anomalous Fine Structure spectroscopy is the unique non destructive method that allows to recover the actual Ge content, the in-plane and out-of-plane strain and to detect atomic ordering. © EDP Sciences and Springer 2009

Embedded set of sensors for power electronic modules

This study deals with the challenges for driving Wide Band Gap modules to maturity. In this study, development, integration and signal processing techniques of several types of sensors are studied. Industrial and academic partners, within CAPTIF project, are proposing complementary skills and experiences in the technological and scientific domains: multi-physic sensors, signal processing, integration and reliability for power electronics. Nanoparticle-based strain gauges, temperature sensors and electromagnetic array sensors will be validated and integrated in power an electronic power module. A specific multi-physic model will be developed in order to specify the best location of interest within the power module. These features will result in a better knowledge of real-time current density location, as well as current frequencies. For both sensor types, the data packaging will be challenging spin-offs. Finally, advanced data processing techniques – estimation as well as signal processing – will be adapted to numerous sensor outputs. A clean room process flowchart will be established to guarantee an advanced pre-industrial prototyping
