  2. Block-stacking problem - Wikipedia

    en.wikipedia.org/wiki/Block-stacking_problem

    The first nine blocks in the solution to the single-wide block-stacking problem with the overhangs indicated. In statics, the block-stacking problem (sometimes known as The Leaning Tower of Lire (Johnson 1955), also the book-stacking problem, or a number of other similar terms) is a puzzle concerning the stacking of blocks at the edge of a table.

  3. Blocking (statistics) - Wikipedia

    en.wikipedia.org/wiki/Blocking_(statistics)

    This is a workable experimental design, but purely from the point of view of statistical accuracy (ignoring any other factors), a better design would be to give each person one regular sole and one new sole, randomly assigning the two types to the left and right shoe of each volunteer. Such a design is called a "randomized complete block design."

  5. Stacking-fault energy - Wikipedia

    en.wikipedia.org/wiki/Stacking-fault_energy

    The equilibrium width is thus partially determined by the stacking-fault energy. When the SFE is high the dissociation of a full dislocation into two partials is energetically unfavorable, and the material can deform either by dislocation glide or cross-slip. Lower SFE materials display wider stacking faults and have more difficulties for cross ...

    en.wikipedia.org/wiki/Stacking_fault

    Comparison of fcc and hcp lattices, explaining the formation of stacking faults in close-packed crystals. In crystallography, a stacking fault is a planar defect that can occur in crystalline materials. [1] [2] Crystalline materials form repeating patterns of layers of atoms. Errors can occur in the sequence of these layers and are known as ...

  7. 2.5D integrated circuit - Wikipedia

    en.wikipedia.org/wiki/2.5D_integrated_circuit

    A 2.5D integrated circuit (2.5D IC) is an advanced packaging technique [1] that combines multiple integrated circuit dies in a single package [2] without stacking them into a three-dimensional integrated circuit (3D-IC) with through-silicon vias (TSVs). [3] The term "2.5D" originated when 3D-ICs with TSVs were quite new and still very difficult.

  9. Three-dimensional integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Three-dimensional...

    This design style requires 3D place-and-route tools, which are unavailable yet. Also, partitioning a design block across multiple dies implies that it cannot be fully tested before die stacking. After die stacking (post-bond testing), a single failed die can render several good dies unusable, undermining yield.
