Said process comprises: - measuring (110) an output power PMC of the complete module; - calculating (130) an estimated output power PDC of said final junction layer of the module based on the first irradiance in a turned-over position of the module, referred to as the second life position, in which the second face of the module becomes the upper face of the module and the first face of the module becomes the lower face of the module; - comparing (140) said estimated output power PDC of said final junction layer with the output power PMC of the complete module measured when the first face is the upper face of the module, in order to send a recommendation to turn over (150) the module when the output power PMC of the complete module in the basic position becomes less than the estimated output power PDC of said final junction layer in the turned-over position of the module. The invention also relates to a module suited to this process.

Abstract
The invention relates to the design of a 3D capacitor comprising inter-digitated nanowires. The nanowires are electrodeposited in a conventional membrane. The electrodeposition is carried out using a mask that is also a membrane. The superposition of the two membranes allows nanowires to be grown in each channel formed by linking a pore of the object membrane with a pore of the mask membrane. By chance, only some of the pores of the object membrane form channels with pores of the mask membrane. The electrodeposition is stopped before the nanowires fill the object membrane. The mask is then removed. A gold film is then sputtered onto the face, which was free, of the object membrane. A second electrodeposition is carried out in the pores that were blocked beforehand by the mask. Once again, deposition is stopped before the nanowires fill the pores. Lastly, a gold film is sputtered onto the side that made contact with the mask.

Abstract
A computer-implemented method for training a deep-learning generative model configured to output 3D modeled objects each representing a mechanical part or an assembly of mechanical parts. The method comprises obtaining a dataset of 3D modeled objects and training the deep-learning generative model based on the dataset. The training includes minimization of a loss. The loss includes a term that penalizes, for each output respective 3D modeled object, one or more functional scores of the respective 3D modeled object. Each functional score measures an extent of non-respect of a respective functional descriptor among one or more functional descriptors, by the mechanical part or the assembly of mechanical parts. This forms an improved solution with respect to outputting 3D modeled objects each representing a mechanical part or an assembly of mechanical parts.

Abstract
The goal of the current invention is a polarimetric microscope working in reflection for the measurement of the refractive index of materials, including both isotropic and uniaxial anisotropic materials, in liquid and solid phases, and in the latter case, measuring both planar and non-planar surfaces. The polarimetric microscope allows measuring the refractive index of optical elements already integrated into devices (as lenses integrated into cameras), and thus, elements that can not be measured in transmission. The associated optical method is also subject of the current invention. It permits, thorough a comparison of experimental data with a theoretical optical model developed by the inventors, the characterization of the optical characteristics of those elements, as their refractive index, the ordinary and extraordinary refractive indices of uniaxial anisotropic materials, or its optical axis orientation. For the accurate and precise measure of the refraction index, the microscope includes confocal measurements.

Abstract
A method for generating ultrashort pulses includes directing a master beam having ultrashort pulses and at least one slave beam through an optical gate material. The intensity of the slave beam upstream of the optical gate material is lower than that of the master beam upstream of the optical gate material. The optical gate material and the pulses of the master beam are chosen to induce a Kerr effect when the master beam passes through the optical gate material, the Kerr effect producing a modulation of the phase of the slave beam in association with pulses of the master beam when the slave beam passes through the optical gate material. The modulation of the phase of the slave beam is transformed into a modulation of the amplitude thereof using a complementary optical device to generate a slave beam downstream of the optical gate material having ultrashort pulses.

Abstract
A device 1 for measuring an angular inclination and angular inclination fluctuations of an electromagnetic radiation beam is described. This device is adapted to detect the incidence angular inclination θ and the relative fluctuations Δθ with respect to a nominal axis of propagation of the beam, in a desired detection plane comprising the nominal propagation axis. The device 1 comprises a first screen 11, a second screen 12 and at least one first electromagnetic power and/or energy detector Ps. The first screen 11 comprises a first slit S1 having a first slit dimension d1 along a first direction x1 on a detection plane transverse to the first slit. The first slit S1 is adapted to determine, when crossed by the beam, a diffraction of the beam, so as to generate downstream of the first screen 11 a diffracted electromagnetic field having on the detection plane a diffraction pattern dependent on the aforementioned angular inclination of incidence θ of the beam. The second screen 12 comprises a second slit S2 having a second slit dimension d2 along a second direction x2, parallel to the aforementioned first direction x1 on the detection plane. The second slit S2 is parallel to the first slit S1 in a direction y perpendicular to the aforementioned first and second directions (x1, x2), and is arranged in a selection position (X) on a scale defined on the second direction x2. The second screen 12 is arranged downstream of the first screen, with respect to the propagation of the beam, and is configured to shield the diffracted electromagnetic field with the exception of a transmitted portion of diffracted electromagnetic field, passing through the second slit S2. The at least one first electromagnetic power and/or energy detector Ps is arranged downstream of the second slit S2, with respect to the propagation of the beam, and is configured to detect the electromagnetic power and/or energy of the transmitted portion of diffracted electromagnetic field, dependent from the diffraction figure. This at least one first electromagnetic power and/or energy detector Ps is further configured to generate a first electrical signal Vs, based on the detected electromagnetic power and / or energy. Since the power and/or electromagnetic energy detected by the first detector depends on the geometry, or on the diffraction pattern, of the diffracted electromagnetic field, which in turn depends on the incidence angular inclination θ of the beam in the detection plane, the aforesaid first electrical signal Vs is representative of the angular inclination of incidence θ of the beam in the detection plane. A system and a method for measuring an angular inclination and angular inclination fluctuations of an electromagnetic radiation beam, using the aforementioned device, are also described. A method for measuring a spatial shift s of a focused laser beam, at the focusing point, with respect to a reference optical axis, is also described.
