Abstract: There is provided a line card configured to mount a module in which a signal transmitted on a line is processed, the line card including a memory, and a processor coupled to the memory and the processor configured to receive information on transmission quality of the signal to be transmitted through the module to be mounted on the line card, extract a combination satisfying the transmission quality among combinations of error correction processing schemes applicable to the module and a framer circuit for performing a signal processing for the signal to be transmitted, and estimate a combination of a range in which temperatures of each of the module and the framer circuit do not exceed a predetermined temperature when the module and the framer circuit are operated by applying the error correcting processing schemes of the combination extracted.

Abstract: An evaluation method for pneumatic tires and a system thereof, is provided, capable of appropriately evaluating an adverse effect, such as deterioration, of tire temperature by expressing severity of a temperature imposed on a member of tire made of rubber or the like in quantitative and convenient manners. Detection counts are calculated for each detected temperature according to a detection counts calculating unit 102 based on information of temperatures of pneumatic tires detected by a temperature sensor of a temperature detector 101. Temperature severity numbers of the pneumatic tires are calculated from a computing equation by a severity calculating unit 104 based on the detection counts and contribution coefficients of deterioration of tire rubber with temperatures stored in a contribution coefficient storage 103 as parameters. Using the calculated temperature severity number, a determination unit 105 determines thermal deterioration of the tire.
