human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge groups authors who co-authored the same paper.

Details of the hypergraph:
Center hyperedge (induced by source paper "Exploration of hardware/software design space through a codesign of robot arm controller"):
  Abstract: This paper deals with exploration of hardware/software design space. The analysis is illustrated using a design of robot arm controller. The controller makes use of an adaptive speed control in real-time. Several architectural solutions are discussed with regard to their performance and cost. The goal is to select the best solution that satisfies the real-time constraints and minimizes the cost.

Includes members:
  Member "Design of an adaptive motors controller based on fuzzy logic using behavioural synthesis":
