Abstract: A method of manufacturing an optoelectronic device including-light-emitting diodes comprising the forming of three-dimensional semiconductor elements made of a III-V compound, each comprising a lower portion and an upper portion and, for each semiconductor element, the forming of an active area covering the top of the upper portion and the forming of at least one semiconductor area of the III-V compound covering the active area. The upper portions are formed by vapor deposition at a pressure lower than 1.33 mPa.

Abstract: The invention concerns a programmable voltage to time converter, comprising: a locking frequency generator configured to generate a locking frequency; a current generator configured to generate a biasing current; a relaxation oscillator configured to be powered by the biasing current and to generate an output voltage signal from the locking frequency, a gain control word and an input voltage signal; a phase difference block configured to determine a phase difference between a first signal corresponding to the output voltage signal and a second signal determined based on the locking frequency. The relaxation oscillator comprises a component presenting a linearly controllable characteristic. The voltage to time converter presents a gain linearly or dB-linearly controllable based on the gain control word by controlling linearly said characteristic of said component.

Abstract: A method for assessing the uranium content in a region of interest of a subsoil using gamma spectrometry includes acquiring at least one energy spectrum of gamma radiation associated with the region of interest. The energy spectrum includes at least one low-energy band, one high-energy band, a contribution of the self-attenuation of uranium in the low-energy band being greater than a contribution of the self-attenuation of uranium in the high-energy band. The method also includes assessing the uranium content in the region of interest using the area of the low-energy band, the area of the high-energy band of the energy spectrum acquired in the region of interest and at least two calibration coefficients.

Abstract: A method for manufacturing a part from a first ceramic or from carbon, consolidated by a second ceramic, having a determined geometry, that involves carrying out the following sequence of steps: a) manufacturing a preform made from an organic polymer; b) impregnating the preform made from an organic polymer with a resin that is a precursor of the first ceramic or a resin that is a precursor of carbon; c) crosslinking and/or polymerising, then pyrolysing the resin that is a precursor of the first ceramic or the resin that is a precursor of carbon; to obtain a part made from a first ceramic or from carbon having the same geometry as the part to be manufactured; e) depositing the second ceramic on the part made from a first ceramic or from carbon by means of a chemical vapour deposition or CVD process or a chemical vapour infiltration or CVI process.

Abstract: A method for resetting an array of RAM cells by applying a sequence of N reset operations, the method including at a first reset operation, defining a first reset technique and performing the first reset operation; at a j-th reset operation of a N−1 subsequent reset operations, j being an integer between 2 and N, if a correction yield of the reset technique used at the (j−1)-th reset operation fulfils a predefined condition, applying the reset technique used at the (j−1)-th reset operation to perform the j-th reset operation, if the correction yield does not fulfil the predefined condition, defining a new reset technique and applying the new reset technique to perform the j-th reset operation, the correction yield being a cumulative correction yield or a relative correction yield, the correction yield for the N reset operations being measured prior to the first reset operation.

Abstract: The invention relates to a method for depositing nano-objects on the surface of a gel comprising the steps of: a) providing a gel having a polymer matrix and a solvent within the polymer matrix, the polymer matrix forming a three-dimensional network which is capable of swelling in the presence of the solvent, wherein the solubility of the polymer matrix in the solvent at 1 bar and 25° C. is less than 1 g/l, wherein the gel has a rigidity gradient on the micrometer scale of less than 10%, then b) depositing nano-objects on the surface of the gel, the nano-objects having a mean diameter greater than or equal to the mean diameter of the pores of the gel, then c) evaporating the solvent from the gel at least until the content of solvent no longer varies over time, under the proviso that, at the start of evaporation, the content of mineral salts in the solvent is less than 6 g/l, the gel capable of being obtained and the uses thereof.

Abstract: A method for determining a spatial-sensitivity function of a gamma camera, the gamma camera observing a field of observation (Ω) liable to contain radiation sources, the gamma camera including a detector material; pixels, distributed over a detecting area, each pixel being configured to form a detection signal under the effect of detection of an interaction of an ionising photon in the detector material; a unit for achieving sub-pixel resolution, the unit being programmed to assign a position (x,y) to each detected interaction on the basis of detection signals formed by a plurality of pixels, the position being determined on a mesh dividing each pixel into a plurality of virtual pixels. The method includes steps allowing weights assigned to each virtual pixel to be determined, each weight corresponding to a sensitivity of each virtual pixel.
