Fatigue is one of the main causes of failures as well as mechanical fractures in structural details made of aluminium alloys under cyclic loading, where the materials (during the crack growth process) are subject to the ...

This work provides a numerical and experimental investigation of fatigue crack growth behavior in steel weldments including crack closure effects and their coupled interaction with weld strength mismatch. A central ...

The use of remote sensing to estimate forest structure has been largely tested but few researches have related such information about canopy closure in tropical forests in steep slope. This work aims to analyze the ...

The dynamics of four source-sink models for an exploited resource under a constant fishing effort are here presented. Two models are described by ordinary differential equations; the other two are expressed by impulsive ...

Moment-closure approximations are an important tool in the analysis of the dynamics on both static and adaptive networks. Here, we provide a broad survey over different approximation schemes by applying each of them to the ...

Quantum computing is an emerging technology with great potential: while quantum computers can solve certain computational problems with a exponentially gain of time in relation of the classical computers implementations, ...

Endoluminal vacuum-assisted closure (E-VAC) is a promising therapy to treat anastomotic leakages of the oesophagus and bowel which are associated with high morbidity and mortality rates. An open-pore polyurethane foam is ...
