Nowadays, people rely heavily on local or cloud storage to store their data digitally. To ensure data safety, various data fault tolerance mechanisms have been widely studied and deployed to provide reliability. Data fault tolerance mechanisms incur additional cost to the storage system. Therefore, data of different importance should be stored on storage that provides different levels of fault tolerance...
Using parallel manipulator into free-form surface polishing process has become a kind of trend, the parallel polishing manipulator system with dynamic feed-forward control which can improve the system response speed and control precision. This will guarantee the practical application and commercially of the parallel polishing machine tool. This paper bases on five degree of freedom parallel polishing...
Non-volatile memory (NVM) has widely participated in the evolution of the next-generation memory architecture by way of being the substitution of the main memory. To cope with the problem of asymmetric read/write speeds of NVM, several excellent researches have been proposed to reduce the number of writes to the NVM-based main memory. Nevertheless, most of these existing approaches do not take the...
A Wireless Sensor Network (WSN) uses a larger number of low-power sensor nodes to gather environmental information which is then wirelessly forwarded to a base station. However, sensor nodes have very limited communication ranges. Thus, relay nodes are required to ensure reliable connectivity throughout the WSN. On the other hand, relay nodes are typically more sophisticated and expensive than sensor...
