  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. Tesla turbine - Wikipedia

    en.wikipedia.org/wiki/Tesla_turbine

    Maximum efficiency comes in this system when the inter-disk spacing approximates the thickness of the boundary layer, and since boundary layer thickness is dependent on viscosity and pressure, the claim that a single design can be used efficiently for a variety of fuels and fluids is incorrect. A Tesla turbine differs from a conventional ...

    en.wikipedia.org/wiki/Science_project

    A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.

  9. 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]
