On a Rotational Smagorinsky model for turbulent fluids: some recent results in the steady and unsteady case

In this paper we summarize and collect several results on a nonlinear rotational model used to simulate large scales in turbulent flows. The model we consider is a generalization of the classical Smagorinsky model and is particularly interesting to properly simulate the vorticity near solid boundaries. We report about existence of weak solution explaining how the use if classical techniques may work or fail showing also perspectives for future studies of more general classes of solutions.

On almost complex embeddings of rational homology balls

We use elementary arguments to prove that none of the Stein rational homology 4-balls shown by the authors and Brendan Owens to embed smoothly but not symplectically in the complex projective plane admit such almost complex embeddings. In particular, we show that those rational balls admit no symplectic embeddings in the complex projective plane without appealing to the work of Evans and Smith.

Digital Curriculum Resources in Digital Mathematics Curriculum: Design Features and Implementation

A digital mathematics curriculum is a complex structure that involves digital environments, where concepts and procedures feature in a close relationship between teacher guidance and knowledge construction by students. This complex structure employs diverse pedagogical approaches and digital resources that could foster the dependency of mathematical knowledge on human participation, and it encompasses multiple domains. This chapter aims to explore design features of digital mathematics curric...

Enhancing Geometric Skills with Digital Technology: The Case of Dynamic Geometry

The emerging Fourth Industrial Revolution (4IR) focuses on smart technology, artificial intelligence, and robotics. Education systems must prepare students for a world where digital–physical artifacts prevail. Education 4.0 is an approach that aims to align with the 4IR, where learner critical skills include complex problem-solving and that involves designing new learning progressions and integrating technology skills into school curricula. This chapter addresses such needs, specifically that...

Some Examples of “Multi-Physical” Fatigue of Organic Matrix Composites for Aircraft Applications

This paper presents, discusses and review some recent results concerning the interaction between mechanics and the environment during fatigue tests carried out under accelerated environmental conditioning of laminated and woven Organic Matrix Composites (OMC) for high temperature aircraft parts, the synergy between electrical and mechanical fields during electro-mechanical fatigue of composite laminates for fuselage applications the damage behavior of 3D woven OMC under thermal cycling.For al...
