    • Extending the relational model with constraint satisfaction 

      Valdron, Michael J. (2021-01-01)
      We propose a new approach to data driven constraint programming. By extending the relational model to handle constraints and variables as first class citizens, we are able to express first order logic SAT problems using ...

    • Integration of heterogeneous data types using self organizing maps 

      Bourennani, Farid (2009-07-01)
      With the growth of computer networks and the advancement of hardware technologies, unprecedented access to data volumes become accessible in a distributed fashion forming heterogeneous data sources. Understanding and ...

    • Modeling mobility patterns 

      Hedrick, Adele M. (2017-11-01)
      This work focuses on analysis and model generation for user mobility patterns given a sequence of observed WiFi signals. Built on the Android platform, the data collection mobile application gathers WiFi sensor readings ...

    • Optimizing relational search with embedded neural network 

      Ma, Limin (2023-04-01)
      Our research focuses on a novel method to query relational data. We propose the partial tuple search problem where a user can utilize keyword search to explore complex relational datasets. The challenge of evaluation of ...

    • Robust curved road boundary identification using hierarchical clustering. 

      Parvin, Nurjahan (2013-11-01)
      We develop a new method for automatic curved road boundary detection in images captured by traffic cameras. The proposed method combines data driven (edge segments) and model based (2nd degree polynomial models for road ...

    • Toward graph layout of large data visualization: algorithms, evaluations and application 

      Ferron, Michael (2016-01-01)
      Generating layouts for millions of points on a spatially-restricted platform is a difficult task with a unique set of constraints. These layouts are traditionally generated on a server out of sight of the user. User-oriented ...

    • Towards a concurrent implementation of keyword search over relational databases. 

      Drake, Richard J.I. (2014-06-01)
      Vast amounts of data are stored in relational databases. Traditionally, querying this data required a deep understanding of the underlying schema in addition to knowledge of a query language such as structured query language ...

    • Towards trusted and efficient temporal relational databases 

      Beirami, Mohammadamin (2018-12-01)
      This research is to develop a blockchain based database based on a relational database management system (RDBMS). The database guarantees authenticity of the stored records using immutable and verifiable signatures. The ...

    • Unified processing of natural language and relational data 

      Stoica, Andrei (2022-09-01)
      This work outlines a method for performing natural language tasks as part of a relational framework. Utilizing features of PostgreSQL as a relational database and its extensibility to allow for word embedding without leaving ...

    • Using Rabin-Karp fingerprints and LevelDB for faster searches 

      Deighton, Richard A. (2012-12-01)
      This thesis represents the results of a study into using fingerprints generated according to the Rabin-Karp Algorithm, and a database LevelDB to achieve Text Search times below GREP, which is a standard command-line UNIX ...
