Covering Segments with Unit Squares [PDF]
Computational Geometry, 2016 We study several variations of line segment covering problem with axis-parallel unit squares in the plane. Given a set S of n line segments, the objective is to find the minimum number of axis-parallel unit squares which cover at least one end-point of ...

Translative Packing of Unit Squares into Squares
International Journal of Mathematics and Mathematical Sciences, 2012 Every collection of n (arbitrary-oriented) unit squares admits a translative packing into any square of side length √2.5⋅𝑛.

The Impact of Visualizing Nested Sets. An Empirical Study on Tree Diagrams and Unit Squares. [PDF]
Front Psychol, 2016 It is an ongoing debate, what properties of visualizations increase people’s performance when solving Bayesian reasoning tasks. In the discussion of the properties of two visualizations, i.e., the tree diagram and the unit square, we emphasize how both ...

Minimum Ply Covering of Points with Unit Squares [PDF]
Workshop on Algorithms and Computation, 2022 Given a set $P$ of points and a set $U$ of axis-parallel unit squares in the Euclidean plane, a minimum ply cover of $P$ with $U$ is a subset of $U$ that covers $P$ and minimizes the number of squares that share a common intersection, called the minimum ...

Statistical Features and Estimation Methods for Half-Logistic Unit-Gompertz Type-I Model
Mathematics, 2023 In this study, we propose a new three-parameter lifetime model based on the type-I half-logistic G family and the unit-Gompertz model, which we named the half-logistic unit Gompertz type-I distribution.

Estimation of transmission line parameters by using two least‐squares methods
IET Generation, Transmission & Distribution, 2021 This work proposes two new approaches based on the ordinary least‐squares method and the total least‐squares method to estimate the parameters of a balanced three‐phase transmission line using voltage and current measurements from phasor measurement unit.

Hardness of Packing, Covering and Partitioning Simple Polygons with Unit Squares [PDF]
IEEE Annual Symposium on Foundations of Computer ScienceWe show that packing axis-aligned unit squares into a simple polygon $P$ is NP-hard, even when $P$ is an orthogonal and orthogonally convex polygon with half-integer coordinates.

Parameters Estimation for the Unit log-log Distribution
Cumhuriyet Science Journal, 2023 In this paper, point estimation problem of two unknown parameters of the unit log-log distribution is examined. For point estimation, six methods of estimate such as maximum likelihood, maximum product spacing, Anderson-Darling, least squares, weighted ...

Properties of the total least squares estimation
Geodesy and Geodynamics, 2012 Through theoretical derivation, some properties of the total least squares estimation are found. The total least squares estimation is the linear transformation of the least squares estimation, and the total least squares estimation is unbiased.
