The method was first proposed by Bernard Roy and his colleagues at SEMA consultancy company. A team at SEMA was working on... |
https://en.wikipedia.org/wiki/Stability%20spectrum | In model theory, a branch of mathematical logic, a complete first-order theory T is called stable in λ (an infinite cardinal number), if the Stone space of every model of T of size ≤ λ has itself size ≤ λ. T is called a stable theory if there is no upper bound for the cardinals κ such that T is stable in κ. The stabili... |
https://en.wikipedia.org/wiki/Ellis%E2%80%93Numakura%20lemma | In mathematics, the Ellis–Numakura lemma states that if S is a non-empty semigroup with a topology such that S is compact and the product is semi-continuous, then S has an idempotent element p, (that is, with pp = p). The lemma is named after Robert Ellis and Katsui Numakura.

https://en.wikipedia.org/wiki/Basic%20dimension | In a technical drawing, a basic dimension is a theoretically exact dimension, given from a datum to a feature of interest. In Geometric dimensioning and tolerancing, basic dimensions are defined as a numerical value used to describe the theoretically exact size, profile, orientation or location of a feature or datum ... |
https://en.wikipedia.org/wiki/Projected%20tolerance%20zone | In geometric dimensioning and tolerancing, a projected tolerance zone is defined to predict the final dimensions and locations of features on a component or assembly subject to tolerance stack-up.

https://en.wikipedia.org/wiki/Voided%20biaxial%20slab | Voided biaxial slabs, sometimes called biaxial slabs or voided slabs, are a type of reinforced concrete slab which incorporates air-filled voids to reduce the volume of concrete required. These voids enable cheaper construction and less environmental impact. Another major benefit of the system is its reduction in slab ... |
https://en.wikipedia.org/wiki/Joint%20Statistical%20Meetings | The Joint Statistical Meetings (JSM) is a professional conference/academic conference for statisticians and data scientists held annually every year since 1840 (usually in August). Billed as "the largest gathering of statisticians held in North America", JSM has attracted over 5000 participants in recent years. The fol... |
https://en.wikipedia.org/wiki/Vortex%20breaker | A vortex breaker is a device used in engineering to stop the formation of a vortex when a fluid (liquid or gas) is drained from a vessel such as a tank or vapor–liquid separator. The formation of vortices can entrain vapor in the liquid stream, leading to poor separation in process steps such as distillation or excessi... |
