Mathematical analysis of Paleodictyon : a graph theory approach

Lethaia, 2005
The graphoglyptid ichnogenus Paleodictyon has been alternatively interpreted as a foraging or farming trace; as a subsurface burrow for the habitation of one or more unknown organisms; the remains of a xenophyophore; and as the result of modular growth of an unknown organism.

Classification of sedimentary and igneous rocks by laser induced breakdown spectroscopy and nanoparticle-enhanced laser induced breakdown spectroscopy combined with principal component analysis and graph theory

Spectrochimica Acta Part B: Atomic Spectroscopy, 2019
In this work, results are presented on the application of standard LIBS and Nanoparticle-Enhanced LIBS (NELIBS) to the classification of rocks (igneous and sedimentary).

[Representation, analysis and application of landscape graph based on graph theory].

Ying yong sheng tai xue bao = The journal of applied ecology, 2020
Landscape structure and spatial pattern are the core issues in landscape ecology. The application of graph theory provides a research framework for landscape pattern analysis. Landscape graph based on graph theory is gradually applied to the connectivity modeling of biodiversity conservation and decision support of landscape planning.

Network meta‐analysis, electrical networks and graph theory

Research Synthesis Methods, 2012
Network meta‐analysis is an active field of research in clinical biostatistics. It aims to combine information from all randomized comparisons among a set of treatments for a given medical condition. We show how graph‐theoretical methods can be applied to network meta‐analysis.

Boundary Theory and Harmonic Analysis on Boundary Transitive Graphs

American Journal of Mathematics, 1994
A boundary transitive graph \(X\) is a locally finite connected graph with infinitely many ends whose automorphism group is noncompact and transitive on the space of ends. One shows that a closed noncompact transitive group \(G\) of automorphisms of \(X\) is of split rank one.

A graph-theory-based approach to the analysis of large-scale plants

Computers & Chemical Engineering, 2007
Abstract On-line balancing of mass and energy in a large-scale plant is today an absolutely feasible operation given the development state of the current data-acquisition systems. However, whilst the computing power is available, not all stream data are available in real-time and the programmed version of the instrumentation flow sheets in form of a ...

Systemic risk in derivative markets: a graph theory analysis

2011
This article inves tigates the time evolution of the integra tion of derivative markets through the graph-theory. We focus on three categor ies of underlying as sets : energy and agricultural products , as well as financial assets . Integration is seen as a necessary condition for systemic risk to appear. In order to fully understand it, this phenomenon
