Computational and topological properties of neural networks by means of graph-theoretic parameters

open access: yesAlexandria Engineering Journal, 2023
A neural network is a computer system modeled on the nerve tissue and nervous system. In this sense, neural networks refer to systems of neurons, either organic or artificial in nature.

Formation, Detection, and Modeling of Submerged Oil: A Review

open access: yesJournal of Marine Science and Engineering, 2020
Submerged oil, oil in the water column (neither at the surface nor on the bottom), was found in the form of oil droplet layers in the mid depths between 900–1300 m in the Gulf of Mexico during and following the Deepwater Horizon oil spill. The subsurface

NUMERICAL PATH-INTEGRATION CALCULATION OF TRANSPORT PROPERTIES OF STAR POLYMERS AND THETA-DLA AGGREGATES

open access: yesCondensed Matter Physics, 2002
Although the calculation of transport properties of complex-shaped particles (Smoluchowski rate constants for diffusion-limited reactions, Stokes friction coefficient, virial coefficients for conductivity, viscosity and other transport properties) is ...

Modeling cumulative biological phenomena with Suppes-Bayes Causal Networks [PDF]

open access: yes, 2018
Several diseases related to cell proliferation are characterized by the accumulation of somatic DNA changes, with respect to wildtype conditions. Cancer and HIV are two common examples of such diseases, where the mutational load in the cancerous/viral ...

Scalable Inference of Customer Similarities from Interactions Data using Dirichlet Processes [PDF]

open access: yes, 2009
Under the sociological theory of homophily, people who are similar to one another are more likely to interact with one another. Marketers often have access to data on interactions among customers from which, with homophily as a guiding principle ...

On the Douglas-Kazakov phase transition [PDF]

open access: yesESAIM: Proceedings and Surveys, 2015
We give a rigorous proof of the fact that a phase transition discovered by Douglas and Kazakov in 1993 in the context of two-dimensional gauge theories occurs. This phase transition can be formulated in terms of the Brownian bridge on the unitary group in large dimension.

A Grasshopper Optimization Algorithm-Based Response Surface Method for Non-Probabilistic Structural Reliability Analysis with an Implicit Performance Function

open access: yesBuildings, 2022
Non-probabilistic reliability analysis has great developmental potential in the field of structural reliability analysis, as it is often difficult to obtain enough samples to construct an accurate probability distribution function of random variables ...

Tourism destinations’ image: assessment vis-à-vis the experience in theory and in the service-centric economy

open access: yesRevista Brasileira de Pesquisa em Turismo, 2016
This paper assesses the image of tourist destinations as products in light of the experience theory, in order to evaluate relationships between both constructs. A scale is set forth to measure the image of coastal destinations, with different attractions,

Envy-Free Allocation by Sperner’s Lemma Adapted to Rotation Shifts in a Company

open access: yesMathematics, 2021
This article discusses a theoretical construction based on the graph theory to rework the space of potential partitions in envy-free distribution. This work has the objective of applying Sperner’s lemma to the distribution of three rotating shifts for ...

Pattern Activation/Recognition Theory of Mind

open access: yesFrontiers in Computational Neuroscience, 2015
In his 2012 book How to Create a Mind, Ray Kurzweil defines a Pattern Recognition Theory of Mind that states that the brain uses millions of pattern recognizers, plus modules to check, organize, and augment them.
