A New Perspective to Graphical Characterization of Multiagent Controllability

IEEE Transactions on Cybernetics, 2017
Recently, graphical characterization of multiagent controllability has been studied extensively. A major effort in the study is to determine controllability directly from topology structures of communication graphs. In this paper, we proposed the concept of controllability destructive nodes, which indicates that the difficulty in graphical ...

Graphical construction of a local perspective on differentiation and integration

Mathematics Education Research Journal, 2014
Recent studies of the transition from school to university mathematics have identified a number of epistemological gaps, including the need to change from an emphasis on equality to that of inequality. Another crucial epistemological change during this transition involves the movement from the pointwise and global perspectives of functions usually ...

A multiple-perspective approach to graphic notation [PDF]

open access: possibleNordic Journal of Music Therapy, 2011
The need to describe and analyze the contents of music therapy sessions, together with the need to find methods of raising therapist awareness, are areas of great interest for the music therapist. In this study an expansion of Bergstrøm-Nielsen’s (1993) method of graphic notation for representing music therapy improvisations is presented ...
