  • Compound Graph Exploration (Bachelor, Master)
    A new graph exploration approach should be examined which is uses different zoom levels for different compound nodes. This tries to map the "Google Maps approach" of only showing the information of interest at any given zoom level to the field of graph exploration.
  • Improvements to Spline Edge Routing (Bachelor, Master)
    Spline edge routing closely follows the routes orthogonal edges would take. A Bachelor's thesis could work on improving how splines connect to their end points to make the results look more natural. A Master's thesis could look at improving the routes splines take through a diagram more generally.
  • Improve Orthogonal Edge Routing (Bachelor)
    The layered layout approach usually uses orthogonal edges to lay out flow-based diagrams. Our orthogonal routing generator, which produces orthogonal edges, suffers from two problems which should be solved as part of a thesis. The problems are tracked as issues 143 and 318 in the ELK project.
  • Control Flow Graph Exploration / Visualization (Bachelor)
    Use pragmatics concepts (automatic layout, focus & context) for exploring/visualizing control flow graphs and specific paths, eg. as computed by OTAWA WCET analysis tool, eg. using KLighD.

Further possible thesis topics can be found in ELK's GitHub repository. Note, however, that some issues there may already be worked on.

Semantics, Synchronous Languages and Model-based Design

...

  • SCCharts Verification (Master/Bachelor)
    Add the possibility to perfom model checking on SCCharts
  • Raceyard evaluation (Master)
    Evaluate the possibility for the use of SCCharts in the Raceyard context and pave the way for future experiments
  • Causality Visualization
    Visualizing causality and scheduling problems in the diagram to guide the modeller

...

  • Optimization of the SCCharts compiler/transformations (Bachelor/Master)
    Profile the actual SCCharts compiler/transformations and apply optimizations; also evaluate the possibility to use multiple cores for compilation.
  • Efficient data dependency & scheduling analyses in SCCharts (Master/Bachelor)
    Implement analyses for data dependencies and scheduling (e.g. tick boundaries) for SCCharts to improve static scheduling of the compiler.
  • Javascript code generation (Bachelor/Master)
    Implement a javascript code generation for SCCharts. Integrate with simulation and (environment) visualization to deploy a complete example as standalone web page. Compare with HipHop.js based on Esterel.

SCCharts Simulation

  • Visualization of Model-based Simulation via Tracing (Bachelor/Master)
    Use the already implemented Model-to-Model-Tracing in KIELER to visualize simulations. 
  • Core SCCharts Interpreter (Master/Bachelor)
    Implement an Interpreter for Core SCCharts.

...

  • Incremental Model-based Compilation of Legacy C Programs (Bachelor/Master)
    Modify the model-based compiler in KIELER so that it is able to compile C to (S)CCharts incrementally.
  • Execution of Recursive Dataflow Code (Master/Bachelor)
  • Execution of Concurrent Dataflow Code (Master/Bachelor)
    Modify the model-based dataflow compiler in KIELER so that it is able to compile recursive/concurrent C programs.
    For Master students: Implement both.

Synchronous Languages

  • eSCL - Implementing gotopause (Bachelor/Master)
    Create an extended dialect of the SC Language including the gotopause statement and implement a transformation to SCL.
