The boundary of a boundary principle: A unified approach
Foundations of Physics, 1986The boundary of a boundary principle in field theories is described. The difference in treatment of the principle in electrodynamics and general relativity is pointed out and reformulated in terms of underlying mathematical structure of the theories. The problem of unifying the treatment is formulated and solved. The role of E.

The authors find it more useful to pay attention to relationships than to boundaries. By focusing attention on bounded, individual psychological issues, the metaphor of boundaries can distract helping professionals from thinking about inequities of power.

THE ‘NO BOUNDARY CONDITION’ OUTFLOW BOUNDARY CONDITION
International Journal for Numerical Methods in Fluids, 1997Summary: We use a one-dimensional model problem of advection-diffusion to investigate the treatment recently advocated by \textit{T. C. Papanastasiou, N. Malamataris} and \textit{K. Ellwood} [Int. J. Numer. Methods Fluids 14, No. 5, 587--608 (1992; Zbl 0747.76039)] to deal with boundary conditions at artificial outflow boundaries. Using finite elements

Boundary Observers for Boundary Control Systems
2020The paper studies the output observation problem for a class of linear distributed parameter systems where both the plant and the observer are modelled as boundary input/output systems. The presented results provide sufficient conditions for the plant and the observer which guarantee the asymptotic output observation to hold.

Active cell components involved in real biological processes have to be close enough to a membrane in order to be able to pass through it. Rough set theory gives a plausible opportunity to model boundary zones around cell-like formations. However, this theory works within conventional set theory, and so to apply its ideas to membrane computing, first ...

STRETCHING THE CONCEPT OF BOUNDARY IN BOUNDARY CRITIQUE
2020The way in which boundary is marked around an issue, determines the way in which we understand, approach and intervene in such an issue. Stretching the way in which we understand the concept of boundary can expand our understanding of how to...
