The branching process with logistic growth [PDF]

open access: yes, 2005
In order to model random density-dependence in population dynamics, we construct the random analogue of the well-known logistic process in the branching process' framework.

The Discrete Infinite Logistic Normal Distribution [PDF]

open access: yes, 2012
We present the discrete infinite logistic normal distribution (DILN), a Bayesian nonparametric prior for mixed membership models. DILN is a generalization of the hierarchical Dirichlet process (HDP) that models correlation structure between the weights ...

A logistic equation with nonlocal interactions [PDF]

open access: yes, 2016
We consider here a logistic equation, modeling processes of nonlocal character both in the diffusion and proliferation terms. More precisely, for populations that propagate according to a L\'evy process and can reach resources in a neighborhood of ...

Visualizing the logistic map with a microcontroller [PDF]

open access: yes, 2011
The logistic map is one of the simplest nonlinear dynamical systems that clearly exhibit the route to chaos. In this paper, we explored the evolution of the logistic map using an open-source microcontroller connected to an array of light emitting diodes (

Learning Logistic Circuits

open access: yes, 2019
This paper proposes a new classification model called logistic circuits. On MNIST and Fashion datasets, our learning algorithm outperforms neural networks that have an order of magnitude more parameters.

Military Logistics vs. Business Logistics

open access: yesEconomic Analysis, 2021
Military logistics as a specific area of logistics management makes the difference between a well-supplied and self-sustainable army which due to an efficiently created supply chain, can perform it’s military actions more efficiently, and an army that, due to insufficient commitment to military logistics activities creates an inefficient army that is ...
