Abstract

A method for transmitting data packets through a random-access (RA) transmission channel shared by a plurality of user terminals uses and exploits a function F for assigning and distributing transmission resources F(u) to the user terminals, knowledge of the graph of which is shared by the sending user terminals and the receiving station in a preliminary step. During the decoding of the received packets, the graph {(u, F(u)} of the assigning and distributing function is exploited by the receiving station to minimize, or even to decrease to zero, the number of replica-location correlations required in case of failure of the conventional CRD-SA protocol decoding process.

Abstract

The present invention relates to a method for treating fragments of polyvinyl butyral (PVB) in which glass shards are encrusted in or on the surface of the PVB. The method involves placing PVB fragments in contact with an aqueous solution comprising a cationic surfactant and a weak base, to obtain a mixture. This mixture, subjected to ultrasound within a defined temperature range, leads to separation of the glass shards and the PVB. In particular, the inventors have discovered that the combined, simultaneous, and complementary action of a weak base, a cationic surfactant, and ultrasound, at an appropriate temperature, made it possible to detach and/or unembed the glass shards fixed to the collected PVB without degrading the polymer matrix.

Abstract

The present invention concerns a method for treating fragments of polyvinyl butyral (PVB) where glass chips are embedded in or at the surface of the PVB. The method consists of placing the fragments of PVB in contact with an aqueous solution comprising a cationic surfactant and a weak base in order to obtain a mixture. Said mixture, subjected to ultrasound in a defined temperature range, leads to the separation of the glass chips and the PVB. In particular, the present inventors have discovered that the combined, simultaneous and complementary action of a weak base, a cationic surfactant and ultrasound, at suitable temperature, makes it possible to detach and/or remove glass chips attached on the collected PVB without degrading the polymer matrix.

Abstract

The invention relates to a process for oxidation of an unsaturated fatty acid by singlet oxygen, which comprises the preparation of a reaction system containing at least the unsaturated fatty acid and molybdate ions, in a mixture of water and an alcohol suitable for compatibilizing the unsaturated fatty acid in the emulsifying system produced in situ, this reaction system being free of exogenous emulsifying agent; and the addition of hydrogen peroxide to this reaction system. This process makes it possible to carry out, in a controlled manner, the allylic oxidation or the epoxidation of the unsaturated fatty acid.

Abstract

The present invention proposes a mechanism allowing active servers to expand their random-access memory by using the available memory in standby servers. The available memory can be used without waking up the standby servers in that a memory manager is implemented which runs on at least one active server and can address with a direct access the memory of the standby servers without requiring the processor of these standby servers to operate. In these servers, at least the memory, the network card and the communication means between servers are then active, while at least their processors are in standby.

Abstract

The induction heating method is implemented in a device for heating a metal part, and comprises magnetically coupled inductors (Ind1, Ind2,..., Indp) powered by inverters (O1, O2,..., Op) and forming an oscillating circuit (OC1, OC2,..., OCp). Each inverter is controlled by control units (M1,1,..., Mp,h) in such a way as to vary the amplitude and the phase of the current passing through the corresponding inductor for each harmonic considered. The method comprises the steps consisting of comparing an actual temperature profile to a reference temperature profile and calculating a profile of the reference power density that the heating device needs to inject into said part from target currents that the inverters need to deliver, taking into account the harmonics of the currents passing through the inductors. The currents passing through the inductors (the fundamental and the harmonics that are to be considered) are compared to said target values and current deviations to be corrected are determined in order to send correction instructions depending on said current deviations.

Abstract

The invention relates to a method for chemical vapour deposition, onto a substrate, of a protective coating made up of at least one protective layer comprising a transition metal M: a) providing, in a supply vessel, a stock solution containing a hydrocarbon solvent free of oxygen atoms and a bis(arene) precursor containing the transition metal M to be deposited; b) vaporising said stock solution and injecting same into a CVD reaction chamber in order to deposit the protective layer onto said substrate and, if need be, a carbon incorporation inhibitor; c) collecting, at the outlet of the reaction chamber, a fraction of the gaseous effluent comprising the non-consumed precursor, the aromatic sub-products of the precursor and the solvent, these species together forming a working solution; and d) pouring the working solution thus obtained into the supply vessel in order to obtain a new stock solution capable of being used in step a).

Abstract

The invention relates to a method for detecting atypical behaviour of telemetry parameters, comprising the following steps: dividing (220) the time interval of detection into a plurality of time windows; for each time window, calculating (230) a set of descriptors according to the measurements of said parameter in said time window, and forming an initial vector from the calculated descriptors; normalising (240) the initial vectors; for each inital vector, reducing (250) the dimension of said initial vector in order to form a reduced vector; determining the association of each reduced vector with a domain defined by a nominal behaviour boundary; and when a reduced vector is outside the domain, generating a warning corresponding to atypical behaviour of the parameter.
