A DRAM includes a substrate voltage generation unit (35) for generating a substrate voltage (Vbb) having a negative value to be applied to a first node (N1). The substrate voltage generation unit (35) includes a detecting circuit (53). The detecting circuit (53) includes a first PMOS ...
gives me the error message SQLSTATE=42829 (The FOR UPDATE clause is not allowed because the table specified by the cursor cannot be modified). 附加信息 I need to specify WITH RR, because I'm running on isolation level READ_COMMITTED, but I need my query to block while there is another ...

The proposed cloud-based condition monitoring and fault diagnosis platform is validated by using a cyber-physical testbed and a computational cost analysis for the CBMP. Therefore, the proposed platform will support the on-board health monitoring and provide an intelligent and cost-effective ...
Leonard is also aware that the light levels used for past displays of the artwork could impact on rates of deterioration, which suggests some acceptance of possible colour change and fading. However, at present it is not known how familiar the artist might be with the unavoidable and ongoing ...
