Modelling the Golomb Ruler
The Golomb ruler problem has been proposed as a challenging constraint satisfaction problem. We consider a large number of di erent models of this problem, both binary and non-binary. The problem can be modelled using quaternary constraints, but in practice using a set of auxiliary variables and ternary constraints gives better results. A binary encoding of the problem gives a smaller search tr...
متن کاملIntroduction of midwifery ruler
In the midwifery profession, measuring pelvic and cervical dilatation is essential for making decisions, especially when the mother is in labor phase. For this reason, several studies have been conducted in pelvimetry.[1‐4] Measurement of the cervix and judgments about pelvic dimensions are performed by the midwifeʹs fingers.

متن کاملUse of an “ Online Ruler ” to Self ‐ Measure Digit Ratio
The ratio between 2nd (index) and 4th (ring) finger lengths (2D:4D) has been proposed to be negatively correlated to prenatal testosterone exposure in humans (Manning, 2002). Evidence for this phenomenon has come from findings of differences between males and females, masculinized 2D:4D in individuals with congenital adrenal hyperplasia (a condition which produces elevated prenatal testosterone...
متن کاملTriangles, Ruler and Compass
A triangle can be specified by giving three independent geometric relationships defined between its elements. Usually, these relationships are distances between two vertices, angles between two sides, and heights. For each triangle specified by a set of three of such relationships, we present a procedure that constructs the triangle using ruler and compass alone. ∗While on leave in Computer Sci...
متن کاملRuler: Programming Type Rules
Some type systems are first described formally, to be sometimes followed by an implementation. Other type systems are first implemented as a language extension, to be sometimes retrofitted into a formal description. In neither case it is an easy task to keep both artefacts consistent. In this paper we present Ruler, a domain specific language for type rules. Our prototype compiler for Ruler bot...
