摘要： A method for non-destructive testing of a plurality of components based on measurement signals, each of the measurement signals corresponding to a predetermined different component, including the following steps: obtaining a sequence of at least one signal portion based on each measurement signal, for each pair associating two signal portions having one and the same position in their respective sequence, a distance between these signal portions of the pair is computed, the distance being computed using dynamic time warping, for each signal portion, determining at least one statistical indicator based on the distances of pairs involving said signal portion, the statistical indicator being associated with the component of said signal portion, and for each component, comparing at least one indicator of the component to indicators of other components, and as a function of the comparison, determining the soundness or unsoundness of the component.

摘要： The present invention relates to a method for detecting, by ultrasound, defects in a material (MS), comprising the steps of transmitting, by M transmitters of index i, and receiving, at sampling times n.Te, by means of M receivers of index j, signals x(n, i, j), forming a sampling matrix (AΔ) having N columns Yn formed by the signals x(n, i, j) for which a distance between the receiver of index j and the transmitter of index i is equal to the deviation Δ and rows Xi,j formed by the signals x(n, i, j), the pair i, j being different from one row Xi,j to the next, calculating a covariance matrix (CΔ) for the projections Xi,jproj,k of the rows Xi,j of the matrix (AΔ) on the K eigenvectors (Vk) corresponding to the K largest eigenvalues (λk), subtracting, from each row Xi,j, the K projections Xi,jproj,k to obtain residual measurement signals x*(n, i, j) for detecting defects.

摘要： A method of constructing a chart of correlations between a rapid discharge and a slow discharge in order to measure the wear of at least one electrochemical cell, including a measurement phase that includes a training sequence followed by a characterization sequence, and an aging phase. Each of the sequences includes charging-relaxing-discharging-relaxing under controlled conditions and is repeated with different conditions. The time of each discharge is measured. The aging phase includes an alternation of charges and discharges with no intermediate relaxation and is implemented before each repetition of the measurement phase, such that a real capacity is obtained for a plurality of pairs of imposed parameters.

摘要： In the management of a facility pumping water from a natural environment containing impurities, the facility makes use of at least one rotary filter purifying the pumped water while some impurities at least partially clog the rotary filter. In particular, provision is made for estimating an evolution over time of a pressure loss caused by impurities clogging the rotary filter, based at least on data relating to the natural environment, dimensions of the rotary filter, and local measurements relating to at least one water level Namont upstream of the filter and to a flow rate of water Qaspiré drawn in downstream of the filter. Such an estimate of the evolution over time of the pressure loss makes it possible to anticipate possible risks of insufficient water supply to the pumping system (POM) downstream of the filter (FIL), or even to design filters (FIL) adapted to the needs of specific pumping facilities.

摘要： A dissymmetric RN,N-dialkylamides of formula (I) in which: R1 represents a linear C1 to C4 alkyl, R2 represents a linear C1 to C10 alkyl, and R3 represents a linear or branched C6 to C15 alkyl, where R3 is different from a n-octyl, n-decyl, n-dodecyl, 2-ethylhexyl and 2-ethyloctyl group when R1 represents a n-butyl group and R2 represents an ethyl group. A method for synthesising the N,N-dialkylamides, and uses of same for extracting uranium and/or plutonium from an aqueous acid solution or for fully or partially separating the uranium from the plutonium contained in an aqueous acid solution and a solution resulting from the dissolution of spent nuclear fuel in nitric acid. A method for treating an aqueous solution resulting from the dissolution of spent nuclear fuel in nitric acid, which allows the uranium and the plutonium contained in the solution to be extracted, separated and decontaminated in a single cycle.
