Time Series Similarity Search In Distributed Key-Value Data Stores Using R-Trees, Aleksey Charapko
UNF Graduate Theses and Dissertations
Time series data are sequences of data points collected at certain time intervals. The advance in mobile and sensor technologies has led to rapid growth in the available amount of time series data. The ability to search large time series data sets can be extremely useful in many applications. In healthcare, a system monitoring vital signals can perform a search against the past data and identify possible health threatening conditions. In engineering, a system can analyze performances of complicated equipment and identify possible failure situations or needs of maintenance based on historical data.
Existing search methods for time series data …
A Comparison Of Cloud Computing Database Security Algorithms, Joseph A. Hoeppner
A Comparison Of Cloud Computing Database Security Algorithms, Joseph A. Hoeppner
UNF Graduate Theses and Dissertations
The cloud database is a relatively new type of distributed database that allows companies and individuals to purchase computing time and memory from a vendor. This allows a user to only pay for the resources they use, which saves them both time and money. While the cloud in general can solve problems that have previously been too costly or time-intensive, it also opens the door to new security problems because of its distributed nature. Several approaches have been proposed to increase the security of cloud databases, though each seems to fall short in one area or another.
