Loaded switches are frequent for the running electric locomotive. The frequencies, phases and amplitudes between the system voltage and residual voltage may be different when the transformer is put into use. The transient responses at different time points are thus analyzed to determine the optimal time to switch on the locomotive transformer and prevent the damage to the system.
This paper proposes a novel system design using a chip multiprocessor (CMP) to provide intrusion tolerance and self-recovery for server applications. Our platform provides three major advantages over previously proposed approaches, 1) security insulation from remote exploits and attacks; 2) close coupling between processor cores in a CMP to ensure immediate logging, fine-grained inspection and fast...
The hardness values of Cr12MoV steel before and after N + and Mo + implantation were measured. AES was used to determine the chemical composition of the implanted layers and the metallographic analysis was conducted. The effect of N + and Mo + implantation on hardness of Cr12MoV steel was discussed.
