  2. Boundary-work - Wikipedia

    en.wikipedia.org/wiki/Boundary-work

    Boundary-work is part of science studies. In boundary-work , boundaries, demarcations, or other divisions between fields of knowledge are created, advocated, attacked, or reinforced. Such delineations often have high stakes for the participants, [ 1 ] and carry the implication that such boundaries are flexible and socially constructed .

  3. Stefan problem - Wikipedia

    en.wikipedia.org/wiki/Stefan_problem

    This is an energy balance which defines the position of the moving interface. Note that this evolving boundary is an unknown (hyper-)surface; hence, Stefan problems are examples of free boundary problems. Analogous problems occur, for example, in the study of porous media flow, mathematical finance and crystal growth from monomer solutions. [1]

  4. Free boundary problem - Wikipedia

    en.wikipedia.org/wiki/Free_boundary_problem

    In mathematics, a free boundary problem (FB problem) is a partial differential equation to be solved for both an unknown function and an unknown domain. The segment Γ {\displaystyle \Gamma } of the boundary of Ω {\displaystyle \Omega } which is not known at the outset of the problem is the free boundary .

  5. Boundary object - Wikipedia

    en.wikipedia.org/wiki/Boundary_object

    This concept has since been widely cited and the concept of a boundary object has been adopted in computer science (particularly computer supported cooperative work), information science, [4] and management, particularly when considering cross-disciplinary work and collaboration, [5] either within one organization or with the boundary object helping to focus the efforts of multiple organizations.

  6. Boundary problem (spatial analysis) - Wikipedia

    en.wikipedia.org/wiki/Boundary_problem_(spatial...

    A boundary problem in analysis is a phenomenon in which geographical patterns are differentiated by the shape and arrangement of boundaries that are drawn for administrative or measurement purposes. The boundary problem occurs because of the loss of neighbors in analyses that depend on the values of the neighbors.

  8. Fuzzy concept - Wikipedia

    en.wikipedia.org/wiki/Fuzzy_concept

    A fuzzy concept is an idea of which the boundaries of application can vary considerably according to context or conditions, instead of being fixed once and for all. [1] This means the idea is somewhat vague or imprecise. [2]

  9. Interface (matter) - Wikipedia

    en.wikipedia.org/wiki/Interface_(matter)

    The interface between matter and air, or matter and vacuum, is called a surface, and studied in surface science. In thermal equilibrium, the regions in contact are called phases, and the interface is called a phase boundary. An example for an interface out of equilibrium is the grain boundary in polycrystalline matter.
