human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "stream processing components isabelle hol formalisation and case studies"):
  Abstract: This set of theories presents an Isabelle/HOL+Isar formalisation of stream processing components introduces in Focus, a framework for formal specification and development of interactive systems. This is an extended and updated version of the formalisation, which was elaborated within the methodology 'Focus on Isabelle'. In addition, we also applied the formalisation on three case studies that cover different application areas: process control (Steam Boiler System), data transmission (FlexRay communication protocol), memory and processing components (Automotive-Gateway System).

Includes members:
  Member "from abstract modelling to remote cyber physical integration interoperability testing":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "towards software development for social robotics systems")
  Member "towards system development methodologies from software to cyber physical domain":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "towards a human centred approach in modelling and testing of cyber physical systems")
  Member "towards focus on time":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "from abstract modelling to remote cyber physical integration interoperability testing")
