Abstract: Method for estimating an axial power imbalance in a nuclear reactor, comprising the following steps: obtaining a reactor power setpoint, for each variable of a plurality of variables of the reactor, determining a sequence of the variable, the sequence representing estimated future variations of the variable, determining a sequence of the axial power imbalance, by taking into account the sequences of the plurality of variables of the reactor, the determination of the sequence of the axial power imbalance using a machine learning module that is trained beforehand on historic reactor data.

Abstract: In the field of nomadic computing, the invention concerns a communicating information processing device affording rapid access to a set of personal information. This device has communication means affording access for it to a communication network, means for local storage of a set of data, means of synchronising this local set of data with at least one remote service accessible via the communication network. The device also has a version of an operating system able, when the device is connected to a terminal of the portable computer type, to enable the latter to boot up, and to load a set of applications managing data stored locally on the device. Advantageously, the set of applications also contains an application managing means of synchronising the local data with the remote service or services.

Abstract: A method for restoring a partial between a peak Pi and a peak Pi+N whose frequency and phase are known. The method (1) comprises the steps of estimating (2) the frequency {circumflex over (?)} of each of the missing peaks Pi+1 to Pi+N?1 of this partial, calculating (3) the phase {circumflex over (?)} from peak to peak, from the phase of the peak Pi to that of the peak Pi+N, for all the frequencies {circumflex over (?)} previously estimated, calculating (4) the phase error err? between the calculated phase {circumflex over (?)} and the known phase at the same peak Pi+N, and correcting (5) each calculated phase {circumflex over (?)} by a value that is a function of the phase error err?.
