Abstract: A method for controlling the deformation of a wheel includes obtaining, for multiple predefined angular positions on the wheel, a parameter characterizing an angular velocity of the wheel when the wheel is in contact with the running surface at each predefined angular position while the wheel is rolling on a running surface, and calculating a radius value of the wheel for each predefined angular position using the parameter characterizing the angular velocity obtained for that angular position.

Abstract: Method and system for communicating data between a transmitter and a receiver via a physical transmission medium interposed there between, wherein the transmitter outputs over the transmission medium towards the receiver, a predefined precursor signal followed by a target signal carrying data packet. Based on the precursor signal received at the receiver, estimated values of actual electrical parameters of the physical transmission medium are computed via a predetermined model of the physical transmission medium, wherein the computed estimated values of the electrical parameters are indicative of a distortion caused by the physical transmission medium on the predefined precursor signal outputted by the transmitter. The data packets originally outputted by the transmitter are estimated based on the computed estimated values of the actual electrical parameters and on the target signal received at the receiver.

Abstract: This thermal conduction device intended to be installed between a first heat source part and a second heat dissipation part, comprises a male element comprising a protruding part relative to a base and a female element comprising an inner wall defining a housing for receiving the protruding part. The male element is configured to exert a radial force against the inner wall when the thermal conduction device is installed between the first heat source part and the second heat dissipation part so as to improve the thermal conduction between the male element and the female element.

Abstract: This method comprises the steps of generating an elementary signature for each electronic board from stored configuration data, transmission to each electronic board of the elementary signature, calculation by each electronic board of the signature variable as a function of the configuration variables, and checking by each electronic board of the validity of the stored configuration variables using the received elementary signature and the signature variable. The method comprises the implementation step for each electronic board for which the configuration variables are considered invalid, and comprises the retrieval of the configuration data specific to this board, and the modification of the configuration variables starting from the configuration data retrieved.

Abstract: A traffic management method, for managing traffic of a transportation network, comprising the steps of managing the traffic and the transportation network, according to a basis instruction timetable, automatically detecting and/or predicting a conflict in the traffic, generating a conflict solution in knowledge of the conflict, and managing the traffic and the transportation network with a modified instruction timetable based on the generated conflict solution. In the invention, the step of generating the conflict solution comprises the sub-steps of automatically splitting the transportation network into a local part, in which the conflict is involved, and a complementary part distinct from the local part, automatically generating a local solution relative only to the local part, automatically generating a complementary solution relative only to the complementary part, the complementary solution being generated in consideration of the local solution, and automatically combining the local and complementary solutions for obtaining the conflict solution.

Abstract: A method is for maintenance of a ground-level power supply for a transport vehicle. The device includes: a power supply rail, a detector of spatial coordinates of a vehicle; and a power supply shoe. The device and the shoe equip the same vehicle. The supply shoe includes a vibration sensor. The method includes measuring vibrations of the shoe and simultaneously detecting spatial coordinates of the vehicle during the movement of the vehicle along the rail, followed by comparing measured vibrations of the shoe with a threshold value, and determining spatial coordinates corresponding to vibrations above the threshold value.
