In this paper, a recovery scheme using two page replacement algorithms for MMDB was implemented. The performance of the recovery mechanism as a function of the number of pages and size of pages was measured. From the results, the recovery time increase almost linearly with the increase in the...

Sufficient processing power, memory, storage, and redundancy should be incorporated to execute required control algorithms. Actuators Interface –Power drivers, SSRs, contactors, relays, valves, switches, indicators etc. interface to external components under system control. Electrical isolation and ...
Thus, while lossy algorithms perform well on image data, loss-less algorithms provide better results on text-based data. Solutions that use a mix of lossy and loss-less data compression are often slow and complex. For example, text and image data are sometimes separated to different channels,...
4.4.1.2 Page Replacement Algorithms When a page in memory needs to be swapped out to free up some physical memory, a page replacement algorithm is used to select which currently in-memory page should be moved to disk. There are a variety of different page replacement algorithms that can be ...
Some advanced cache replacement algorithms [16], [19] define their own custom cost indexes to enhance cache hit rates and reduce expenses associated with fetching objects from origin servers. GD-size (greedy-dual size) considers both the size and fetching cost of an object, while SW-LFU (serv...
