Active infrared thermography has been used for the detection of sub surface defects in road materials. The step heating method was selected, and two different infrared cameras selected. Defects were detected with an heating phase as short as 60 seconds. Some images treatments were employed, and have been able to extract signal in spite of the porosity and of the high heterogeneity of a road mat...

There are settings where encryption must be performed by a sender under a time constraint. This paper describes an encryption/decryption algorithm based on modular arithmetic of complex integers called Gaussians. It is shown how cubic extractors operate and how to find all cubic roots of the Gaussian. All validations (proofs) are provided in the Appendix. Detailed numeric illustrations explain ...

This deliverable presents the validations and proofs of concept of methodologies and technical solutions elaborated in the LEXNET project. Part-A details the developed EMF measurement tools and their characterization. Different methods for the Exposure Index (EI) assessment are implemented and demonstrated in various environments. In Part-B, a set of promising low EMF components and techniques ...

A conservative level-set model for direct simulation of two-phase flows with thermocapillary effects at dynamically deformable interface is presented. The Navier-Stokes equations coupled with the energy conservation equation are solved by means of a finitevolume/level-set method. Some numerical examples including thermocapillary motion of single and multiple fluid particles are computed by mean...

The level of automation employed in semi-automated assembly systems is crucial, both to system performance and cost. This paper presents a methodology to enable selection of the right Level of Automation. The method thoroughly maps existing product and information flows as well as the automation level in separate parts of the system. It then analyses and identifies future automation possibiliti...

Since lidars are becoming industrial instruments, it is mandatory to ensure a good traceability of parameters and performances for all users. For most Doppler lidar applications, an accurate metrology is required, first of course for the radial wind component, but also for range and line of sight direction. In order to give to the user the more reliable information about its products, Leosphere...

Computational fluid dynamics is implemented to investigate the influence of the wheel contact patch on the global car aerodynamics. Two main aspects of the problem are the contact step and patch shape. Three important parameters: step height, cut angle, and tire tread shape are taken into consideration. For validations of the numerical results, the experimental data are also considered. The obt...
