A model of compression combustion noise is set up to simulate combustion waves from chamber, which is validated at test bench. The major Influence factors of combustion waves are optimized and proved at test bench and in the anechoic chamber. Test result shows that injection control strategy including multi-injection, single pilot injection and double pilot has remarkable influence on compression...
JEDEC DDR4 SDRAM adopted the internal Data (DQ) reference voltage (VREFDQ) generation scheme as opposed to DDR3 SDRAM where VREF was generated by an external device that produced fixed (constant) voltage irrespective of the loading on the device, power supply variations, temperature changes, and the passage of time. With the introduction of Per DRAM Addressability (PDA) in DDR4 memory and the internal...
Automatic control of the clutch is the key technology in the development of electronic control and mechanical automatic transmission. A control system of Automatic clutch is studied which is Based on the dynamic behavior of the process of clutch engagement and performance evaluation index of integrated analysis. The control strategy of the clutch engagement process is determined and it is also applied...
Many real-time communication protocols have been studied to guarantee the communication requirements of distributed real-time systems. But, current techniques lack all or most of these requirements specially bounded message delivery time. In this paper we have proposed a Mac layer protocol called RDM+ with concepts similar to Round Data Mailer multi layer protocol. Our simulation results show that...
