Advanced digital signal processing for color X-ray imaging
Offer N°: SL-DRT-15-0542
Over the last few years there is a growing interest in energy sensitive X-ray detector for color imaging for health, security and non-destructive test applications. Compared to standard radiographic techniques, color imaging provides quantitative information on the density and effective atomic number of the imaged materials.
Semipolar Nitride materials templates for short wavelength visible emission
Offer N°: SL-DRT-15-0538
III-nitride semiconducting materials are used for the realization of blue diodes at the heart of LED lamps. But when it comes to longer wavelengths (green to red) in the visible domain, these materials encounter difficulties linked to the existence of internal piezoelectric fields that spatially separate electrons and holes in the active region(quantum wells)of the diode, reducing the radiative efficiency.
Polar codes for 5G wireless systems
Offer N°: SL-DRT-15-0489
Error correcting codes are an essential component of any communication system, as they provide an effective solution for reliable communications over noisy transmission channels. Polar codes are a recently discovered family of error correcting codes, which are known to achieve the capacity of memoryless symmetric channels.
Development of a new interformetric microscopy for the 3d imaging of biological 3d complexes structures
Offer N°: SL-DRT-15-0504
Our laboratory develops unconventional microscopy techniques like lensless and interferometric microscopy. The subject of this thesis is to extend a previous work dedicated to microbiology to more complex structures like cells network and skin tissues. During this thesis, the student will further develop the instrument and the processing method to provide true 3D images without specimen labelling.
