human: Given a node-centered hypergraph: <hypergraph>, where nodes represent authors and hyperedges represent groups of authors who co-authored the same paper.

Details of the hypergraph:
Center node: "Compiling Graphical Real-Time Specifications into Silicon"
  Abstract: The basic algorithms underlying an automatic hardware synthesis environment using fully formal graphical requirements specifications as source language are outlined. The source language is real-time symbolic timing diagrams [3], which are a metric-time temporal logic such that hard real-time constraints have to be dealt with.

Connected through hyperedge HE-1 (induced by source paper "The ICOS Synthesis Environment"):
  with members:
    (none)

Question: Please tell me which research area the center author belongs to. The 4 classes are: Computer science, Mathematics, Engineering, Economics, Psychology, Business. Directly output the class name.
