      Sandel, Roni (2015-08-28)
      Cloud computing is increasingly being adopted due to its cost savings and abilities to scale. As data continues to grow rapidly, an increasing amount of institutions are adopting non standard SQL clusters to address the ...
    • Efficient Calculation of Optimal Configuration Processes 

      Fernandez, Yasser Gonzalez (2015-12-16)
      Customers are getting increasingly involved in the design of the products and services they choose by specifying their desired characteristics. As a result, configuration systems have become essential technologies to support ...
    • Exploiting semantics for improving clinical information retrieval 

      Babashzadeh, Atanaz (2016-06-23)
      Clinical information retrieval (IR) presents several challenges including terminology mismatch and granularity mismatch. One of the main objectives in clinical IR is to fill the semantic gap among the queries and documents ...
