Challenges in finding stable price zones in European electricity markets: Aiming to square the circle?The European day-ahead electricity market is split into multiple bidding zones with a uniform price. The inc
To find the area and circumference of a circle, one must know how to draw a circle. A circle is drawn as a closed arc around a center point. Circles have a constant distance between the center point of the circle and any point on the edge of the circle. This distance is called the...

Then the entire set fits in a circle around p, of radius lpql, and the perimeter must be at least 21pql. However, we can cover the circle with 16 squares of perimeter IPql; if q is not among the 16k rectilinear nearest neighbors of p, then some square must contain at least k ...
A circle with a large radius R or small curvature κ is therefore transformed into a line that passes very close to the origin (Fig. 5.1). In the limit of zero curvature, the circle becomes a line transformed into itself by the mapping in Eq. (5.1). Both circle finding and circle ...

While the Sustainable Development Goal (SDG) index is a widely employed method of measuring progress in the United Nations (UN) SDGs, as it allows comparisons across countries and regions, it does not usually offer any indication as to how to move the SDGs forward. To address this deficit, ...
