TRANSLATIVE PACKING TWO SQUARES IN THE UNIT SQUARE

open access: yesDemonstratio Mathematica, 2003
For a given square \(S\) and a sequence \((S_n)\) of squares in the plane, we say that \((S_n)\) can be translatively packed in \(S\) if there exist translations \(\tau_i\) such that the translates \(\tau_i S_i\) \((i= 1,\dots, n)\) have pairwise disjoint interiors and are subsets of \(S\).

Different estimation methods for the generalized unit half-logistic geometric distribution: Using ranked set sampling

open access: yesAIP Advances, 2023
The generalized unit half-logistic geometric distribution (GUHLGD) is a modern two-parameter unit distribution with attractive shape flexibility for the corresponding probability density and hazard rate functions.
