SPAG: A New Measure of Spatial Agglomeration. Theoretical Background and Empirical Examples1

Quaestiones Geographicae, 2018
Kopczewska (2017) proposed a new empirical measure of spatial agglomeration (SPAG) of economic activity based on geolocations of firms. The aim of the paper is to introduce theoretical backgrounds of SPAG. The measure is a product of two random variables

Line Sampling with Probability Proportional to The Geometrical Average Area Per Tree in The Stand [PDF]

Floresta e Ambiente
The study proposes a sampling method, termed the probability proportional to the average geometric area of occupation, method in which a set of trees along a row is selected as the sampling unit with a probability proportional to the geometrical average ...

Modeling Quantum Dot Systems as Random Geometric Graphs with Probability Amplitude-Based Weighted Links

Nanomaterials, 2021
This paper focuses on modeling a disorder ensemble of quantum dots (QDs) as a special kind of Random Geometric Graphs (RGG) with weighted links. We compute any link weight as the overlap integral (or electron probability amplitude) between the QDs ...

Classification and properties of acyclic discrete phase-type distributions based on geometric and shifted geometric distributions

Journal of Industrial Engineering International, 2018
Acyclic phase-type distributions form a versatile model, serving as approximations to many probability distributions in various circumstances. They exhibit special properties and characteristics that usually make their applications attractive.

On a Geometric Representation of Probability Laws and of a Coherent Prevision-Function According to Subjectivistic Conception of Probability

Ratio Mathematica, 2018
We distinguish the two extreme aspects of the logic of certainty by identifying their corresponding structures into a linear space. We extend probability laws P formally admissible in terms of coherence to random quantities.

Quantum Information Dimension and Geometric Entropy

PRX Quantum, 2022
Geometric quantum mechanics, through its differential-geometric underpinning, provides additional tools of analysis and interpretation that bring quantum mechanics closer to classical mechanics: state spaces in both are continuous and equipped with ...

Symmetry and Correspondence of Algorithmic Complexity over Geometric, Spatial and Topological Representations

Entropy, 2018
We introduce a definition of algorithmic symmetry in the context of geometric and spatial complexity able to capture mathematical aspects of different objects using as a case study polyominoes and polyhedral graphs.
