Some studies on databases.
Here are some simple tests using Lightweight Modular Staging (http://scala-lms.github.io/) as a code generating scheme for producing C code implementing different and combinable optimizations (variants) of the Scan operation for a database. Branch removal, thread parallelization, vectorization using SSE instructions and loop unrolling are included in this release. GPU parallelization has also been tested and will be included in the future. Project carried out at the University of Magdeburg Oct 2014-Apr 2015

Some studies on databases.
Just some early experiments on different ideas for supporting code retrieval. Part of an upcoming student project to be carried out at OvGU-Magdeburg, under the supervision of Tatiana Gossen.
Some ideas for a parallel radix join operator, using pthreads and testing a branching approach to task-based parallelization. This was developed as a Scientific Team Project from the DBSE workgroup at the University of Magdeburg, during the Summer Semester 2014.
In this repository are some files from a study on how to support cross-language recommendations for an existing research paper recommender system. We focused on German, English and Spanish. Latent semantic indexing and a framework for automatic translation (enriched with query reformulation and semantic query expansion) were studied. This was a project carried out at the University of Magdeburg Oct 2014-Feb 2015.
