Anatomy of Failures: Stability Requirements in All Stages of Operations [PDF]

open access: yesMATEC Web of Conferences, 2019
The paper provides examples of how temporary conditions experienced during construction, retrofit, or repair can bring an otherwise robust structure to failure.

Feral Cat Populations and Feline Retrovirus Prevalence in San Mateo County, California in Three Time Periods between 2001 and 2016

open access: yesAnimals, 2022
This study was initiated in 2004 because the prevalence of feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infections in feral cats in San Mateo County (SMC) was not known.

The Critical Exponent is Computable for Automatic Sequences

open access: yes, 2011
The critical exponent of an infinite word is defined to be the supremum of the exponent of each of its factors. For k-automatic sequences, we show that this critical exponent is always either a rational number or infinite, and its value is computable ...

Antisquares and Critical Exponents

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
The (bitwise) complement $\overline{x}$ of a binary word $x$ is obtained by changing each $0$ in $x$ to $1$ and vice versa. An $\textit{antisquare}$ is a nonempty word of the form $x\, \overline{x}$. In this paper, we study infinite binary words that do not contain arbitrarily large antisquares.

Delay-Exponent of Bilayer Anytime Code

open access: yes, 2014
In this paper, we study the design and the delay-exponent of anytime codes over a three terminal relay network. We propose a bilayer anytime code based on anytime spatially coupled low-density parity-check (LDPC) codes and investigate the anytime ...

Ljapunov Exponents, Hyperchaos and Hurst Exponent

open access: yesZeitschrift für Naturforschung A, 2005
Abstract We consider nonlinear dynamical systems with chaotic and hyperchaotic behaviour.We investigate the behaviour of the Hurst exponent at the transition from chaos to hyperchaos. A two-dimensional coupled logistic map is studied.

Recovering a variable exponent

open access: yesDocumenta Mathematica, 2021
We consider an inverse problem of recovering the non-linearity in the one dimensional variable exponent p(x) -Laplace equation from the Dirichlet-to-Neumann map. The variable exponent can be recovered up to the natural obstruction of rearrangements.

Detecting the Temporal Scaling Behavior of the Normalized Difference Vegetation Index Time Series in China Using a Detrended Fluctuation Analysis

open access: yesRemote Sensing, 2015
Vegetation is an important part of terrestrial ecosystems. Although vegetation dynamics have explicit spatial and temporal dimensions, the study of the temporal process is in its infancy.

Allometric Exponent and Randomness

open access: yes, 2013
An allometric height-mass exponent $\gamma$ gives an approximative power-law relation $ \propto H^\gamma$ between the average mass $$ and the height $H$, for a sample of individuals.
