Existence of Minimizers for Fractional Variational Problems Containing Caputo Derivatives

, 2013
International audienceWe study dynamic minimization problems of the calculus of variations with Lagrangian functionals containing Riemann–Liouville fractional integrals, classical and Caputo fractional derivatives.

An efficient discrete Chebyshev polynomials strategy for tempered time fractional nonlinear Schrödinger problems

Journal of Advanced Research
Introduction: An interesting type of fractional derivatives that has received widespread attention in recent years is the tempered fractional derivatives. These fractional derivatives are a generalization of the well-known fractional derivatives, such as

Knock‐knock, who is inside? Exploiting citizen science data to shed light on Aedes albopictus indoor presence in southern Europe

People and Nature, EarlyView.
Abstract Animal behaviour in human‐dominated landscapes is difficult to study at large spatial and temporal scales, especially for small species characterised by elusive movements. Citizen science can help overcome these limitations by turning routine human–animal encounters into observations of where and when species are active.

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

Journal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

An Uncommon Instance of Egyptian Blue in the “Pigmented Intonachino” of the Fishpond Wall Painting From the Roman Villa of Torre di Pordenone (Northeast Italy)

Archaeometry, EarlyView.
ABSTRACT The increasingly close integration of analytical techniques in the study of Greek and Roman wall paintings has shown that Egyptian blue was a common pigment, widely documented in the production of blue and greenish hues in ancient painted production.
