Solution for harvesting wave energy with Wells turbines and protection of the Black Sea coast by Budea Sanda, Simionescu Ștefan-Mugur, Florea George-Fabian

“…Two models of Wells turbines, with NACA 0010 and NACA 0021 blade profiles, were tested in the laboratory with air and water as working fluids, in two variants of operation – stand-alone rotor and with guide blades. Estimates and comparisons have been made regarding the energy that can be harvested using Wells turbines with 101 mm diameter rotors. …”

Fundamental Results of Conformable Sturm-Liouville Eigenvalue Problems by Mohammed Al-Refai, Thabet Abdeljawad

“…We prove that the eigenvalues are real and simple and the eigenfunctions corresponding to distinct eigenvalues are orthogonal and we establish a fractional Rayleigh Quotient result that can be used to estimate the first eigenvalue. Despite the fact that the properties of the fractional Sturm-Liouville problem with conformable derivative are very similar to the ones with the classical derivative, we find that the fractional problem does not display an infinite number of eigenfunctions for arbitrary boundary conditions. …”

An international award-winning photograph illustrates how graphics convey climate change communication messages by Deborah HILTON

“…Climate change effects are becoming extreme, persistent and permanent, with negative ramifications on agriculture, more extreme weather catastrophes, detrimental effects on human physical and mental health, destruction of small islands and while economic impacts are difficult to estimate overall the situation is apocalyptic. Policy action should address urgent issues, and consistency requires climate change under- standing including knowledge of the human and environmental connections. …”

Buckling suppression of a cantilever structure with a modified fuzzy sliding mode control by Jianhua Pan, Lin Sun, Xiaopei Liu, Yuyuan Zhang, Yili Duo

“…Numerical simulations demonstrate that a two-dimensional nonlinear dynamic model of the laminated composite structure is essential for precise buckling vibration estimations. Therefore, a new active control strategy for large-amplitude buckling suppression of a two-dimensional nonlinear dynamic system of a cantilever beam is established and implemented, effectively suppressing the large-amplitude buckling response in numerical studies.…”
