Accurate Boundary Conditions for Twin Boundary

Communications in Computational Physics, 2021
In this paper a heterogeneous lattice with twin boundary is considered. The authors develop some accurate boundary conditions for treating the numerical boundary in the problem under consideration. These conditions include time history kernel (THK) treatment and matching boundary conditions (MBC).

Boundary Crossing and Boundary Objects

Review of Educational Research, 2011
Diversity and mobility in education and work present a paramount challenge that needs better conceptualization in educational theory. This challenge has been addressed by educational scholars with the notion of boundaries, particularly by the concepts of boundary crossing and boundary objects.

Technology for boundaries

Proceedings of the 2003 international ACM SIGGROUP conference on Supporting group work, 2003
This paper presents a study of an organisation, which is undergoing a process transforming organisational and technological boundaries. In particular, we shall look at three kinds of boundaries: the work to maintain and change the boundary between the organisation and its customers; boundaries between competencies within the organisation; and ...

Boundaries. Boundaries…Boundaries???

Current Opinion in Cell Biology, 2008
One way to modulate transcription is by partitioning the chromatin fiber within the nucleus into the active or inactive domains through the establishment of higher-order chromatin structure. Such subdivision of chromatin implies the existence of insulators and boundaries that delimit differentially regulated chromosomal loci. Recently published data on

Pressure boundary conditions for immersed-boundary methods

Journal of Computational Physics, 2023
Immersed boundary methods have seen an enormous increase in popularity over the past two decades, especially for problems involving complex moving/deforming boundaries. In most cases, the boundary conditions on the immersed body are enforced via forcing functions in the momentum equations, which in the case of fractional step methods may be problematic

Capacity of the Boundary and of a Boundary Component

The Annals of Mathematics, 1954
1. In several existence and extremal problems on Riemann surfaces, it is useful to characterize the type of the surface by certain conformally invariant measures.

Viewing boundary 'objects' as boundary constructions

Proceedings of the 41st Annual Hawaii International Conference on System Sciences (HICSS 2008), 2008
Empirical results from a qualitative study within an important North American aircraft engine manufacturing company allows us to propose an alternative framework for achieving effective knowledge sharing based on the boundary construction concept. Tapping into Latour's (1993) epistemological insights of mutual transformation, hybridization and inter ...

Boundaries and Boundary Violations

2012
A personal boundary is a fundamental component of selfhood; it refers to the ability to define one's self as an independent individual deserving of fair, respectful, nonexploitive treatment that is informed by widely accepted standards of legal and human rights.
