Abstract: According to one embodiment, a platooning operation system organizes a platoon by making a plurality of vehicles cooperate. The platooning operation system includes an application acceptance processor and a platoon organization processor. The application acceptance processor accepts an application of a vehicle for admission to the platoon. The platoon organization processor which selects a platoon to which the vehicle is to be admitted or determines possibility of admission of the vehicle to the platoon, based on at least one of information on a driver driving the vehicle and information on the vehicle.

Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a plurality of projection data based on an output signal from an X-ray detector that rotates around a subject, performs reconstruction filter processing on the plurality of acquired projection data, the reconstruction filter processing being included in reconstruction regarding the plurality of projection data, generates correction information on a sensitivity difference area formed in the plurality of projection data due to differences in sensitivity of the X-ray detector, on the basis of a processing result of the reconstruction filter processing, performs correction processing on the plurality of projection data on the basis of the correction information, and performs reconstruction processing including the reconstruction filter processing on the plurality of projection data subjected to the correction processing.

Abstract: In a network system according to the present invention, in the case where a plurality of calls are set between specific terminal and the other terminal unit to conduct communication, when a communication fault is detected in a frame relay network, a representative call is decided from the plurality of calls, and all the calls except for the representative call are released. Thereafter, a call cut message including information relating to the calls to be released is transmitted from the frame relay network. In the specific terminal, the calls except for the representative call are released on the basis of the information of the calls to be released which is contained in the call cut message to transmit the call release message of the representative call. In the frame relay network, the representative call is released according to the call release message to transmit the call release completion message. Then, in the specific terminal, the representative call is released.
