Abstract: A method for determining the state of a system among a plurality of states, includes acquiring values of a reference physical quantity of the system corresponding to a plurality of points in an original space, each value being paired with one point of the plurality of points and with one state of the system; embedding a portion of the points in a representation space, the representation space being in bijection with a sub-variety of the original space, each point in the representation space being paired with one state; determining a pairing function that pairs any position of the original space with a position in the representation space; determining the position in the representation space of a point of the original space paired with an acquired value, and determining the state of the system from the position of the point paired with the acquired value in the representation space.

Abstract: This method for training a binarized neural network, also called BNN, including neurons, with a binary weight for each connection between two neurons, is implemented by an electronic circuit and comprises: a forward pass including calculating an output vector by applying the BNN on an input vector; a backward pass including computing an error vector from the calculated output vector, and calculating a new value of the input vector by applying the BNN on the error vector; a weight update including computing a product by multiplying an element of the error vector with one of the new value of the input vector, modifying a latent variable depending on the product; and updating the weight with the latent variable; each weight being encoded using a primary memory component;
each latent variable being encoded using a secondary memory component having a characteristic subject to a time drift.-

Abstract: A magnetic field sensor includes at least one coil responsive to an AC coil drive signal; at least one magnetic field sensing element responsive to a sensing element drive signal and configured to detect a directly coupled magnetic field generated by the at least one coil and to generate a magnetic field signal in response to the directly coupled magnetic field; a processor responsive to the magnetic field signal to compute a sensitivity value associated with detection of the directly coupled magnetic field and substantially independent of a reflected magnetic field reflected by a conductive target disposed proximate to the at least one magnetic field sensing element; and an output signal generator configured to generate an output signal of the magnetic field sensor indicative of the reflected magnetic field.

Abstract: The use of carbamides as extractants for fully or partially separating uranium(VI) from plutonium(IV) in an aqueous solution obtained by dissolving a spent nuclear fuel in nitric acid, by method of liquid-liquid extraction, without carrying out any reduction of the plutonium(IV) to plutonium(III). The invention also relates to new carbamides. Uses are the processing of spent nuclear fuels based on uranium (especially uranium oxides—UOX) or uranium and plutonium (especially mixed uranium and plutonium oxides—MOX).
