I. Introduction: Challenges in energy savings for turbines engines Nickel-based superalloys can withstand high temperatures and severe oxidizing conditions, while maintaining superb mechanical properties. Because of this, they are widely used for aerospace and power generation applications. Since higher operating temperature leads to greater cycle efficiency, there are economic and environmenta...

have a unique assemblage structure. For these assemblages, an alternative explanation might be more appropriately sought at a smaller spatial scale to match the reduced geographical extent of these idiosyncratic reefs relative to a coherent province (Rahbek 2005, Fenberg et al. 2014). Coral assemblages located in marginal areas, such as those at higher latitudes, are of particular interest beca...

A methodology for safety verification of nonlinear systems using barrier certificates has been proposed recently. The condition was stated in a sufficiency form: if there exists a barrier certificate, then the system is safe, in the sense that there is no trajectory starting from a given set of initial states that reaches a given unsafe region. Using the concepts of convex duality and density f...

Over recent years, researchers have used full-scale motorcycle crash tests in the field of road safety research to simulate different types of crash technique and scenario. This study focuses on the development of laboratory-based motorcycle crash tests. A moveable barrier, designated as a ‘trolley’ in this study, is designed, developed and implemented in a laboratory-based motorcycle crash tes...

The dynamics of a baby skyrmion configuration, in a model Landau-Lifshitz equation, was studied in the presence of various potential obstructions. The baby skyrmion configuration was constructed from two Q = 1 hedgehog solutions to the baby skyrme model in (2+1)dimensions. The potential obstructions were created by introducing a new term into the Lagrangian which resulted in a localised inhomog...

Method for data fusion between Microwave Scanning Radiometer: MSR and Thermal Infrared Radiometer: TIR derived skin sea surface temperature: SSST, wind speed: WS and salinity is proposed. SSST can be estimated with MSR and TIR radiometer data. Although the contribution ocean depth to MSR and TIR radiometer data are different each other, SSST estimation can be refined through comparisons between...

Nuclear pore complexes (NPCs) are highly selective filters that control the exchange of material between nucleus and cytoplasm. The principles that govern selective filtering by NPCs are not fully understood. Previous studies find that cellular proteins capable of fast translocation through NPCs (transport receptors) are characterized by a high proportion of hydrophobic surface regions. Our ana...

Global climate change and increasing urbanization worldwide intensify the need for a better understanding of human heat stress dynamics in urban systems. During heat waves, which are expected to increase in number and intensity, the development of urban cool islands could be a lifesaver for many elderly and vulnerable people. The use of remote sensing data offers the unique possibility to study...

We consider a smooth Tonelli Lagrangian L : TTn → R and its viscosity solutions u(x, P ) characterized by the cell equation H(x, P + Dxu(x, P )) = H(P ), where H : T ∗Tn → R is the Hamiltonian associated with L. We will show that if P0 corresponds to a quasi-periodic Lagrangian invariant torus, then Dxu(x, P ) is Hölder continuous in P at P0 with Hölder exponent arbitrarily close to 1, and if b...
