Today's file systems typically need multiple disk accesses for a single read operation of a file. In the worst case, when none of the needed data is already in the cache, the metadata for each component of the file path has to be read in. Once the metadata of the file has been obtained, an additional disk access is needed to read the actual file data. For a target scenario consisting almost exclusively...
Data deduplication systems discover and remove redundancies between data blocks. The search for redundant data blocks is often based on hashing the content of a block and comparing the resulting hash value with already stored entries inside an index. The limited random IO performance of hard disks limits the overall throughput of such systems, if the index does not fit into main memory. This paper...
Due to the importance of transformers to power systems, investments in studies are justified in order to develop mathematical models to better understand equipment characteristics. The methodology used in this study consisted of the traditional open and short-circuit tests of the transformer to determine the equivalent circuit parameters and the frequency response of the system. The task was then...
