Stabilization of homogeneous conformable fractional-order systems

Ukrains’kyi Matematychnyi Zhurnal
UDC 517.9 We propose an explicit homogeneous feedback control under the assumption that a control Lyapunov function exists for an affine control conformable fractional-order system and satisfies a homogeneity condition. Furthermore, we demonstrate that the existence of a homogeneous control Lyapunov function for a homogeneous affine  conformable ...

Diel feeding rhythm of copepod size-fractions from Coliumo Bay, Central Chile

Scientia Marina, 2001
The feeding behaviour of the size fractionated copepod assemblage was studied over a diel cycle in Coliumo Bay. In this shallow environment the photic layer reached the bottom and salinity, temperature, and food availability were fairly homogeneous ...

Eigenvalues homogenization for the fractional \(p\)-Laplacian

Electronic Journal of Differential Equations, 2016
In this work we study the homogenization for eigenvalues of the fractional p-Laplace operator in a bounded domain both with Dirichlet and Neumann conditions. We obtain the convergence of eigenvalues and the explicit order of the convergence rates when periodic weights are considered.

Laser Powder Bed Fusion of Copper–Tungsten Composites for Heat Sink Applications in High‐Power Electronics

Advanced Engineering Materials, EarlyView.
This article demonstrates the successful qualification of a copper–tungsten composite for laser powder bed fusion. The resulting components exhibited high density, high thermal conductivity, and reduced thermal expansion. Heat sinks with complex geometries were successfully manufactured, clearly showcasing the material's potential for additive ...

Efficient Process Development for Laser Powder Bed Fusion of a Soft‐Magnetic Metallic Glass Composite

Advanced Engineering Materials, EarlyView.
Iron‐based metallic glass alloys exhibit excellent soft‐magnetic properties, and unprecedented geometrical freedom in the design of soft‐magnetic metallic glass components is made possible by additive manufacturing. An efficient workflow for developing parameters for laser‐based powder bed fusion of a Fe‐based metallic glass alloy is presented along ...

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Fractional integration along homogeneous curves in $R^3$

MATHEMATICA SCANDINAVICA, 1999
Given the curve \(\Gamma(t)=(t^\alpha, t^\beta, t^\gamma)\), \(t>0\), in \(\mathbb R^3\), with \(\alpha0\), \(T^\sigma\) is bounded from \(L^p(\mathbb R^3)\) to \(L^q(\mathbb R^3)\) if and only if \((\frac{1}{p}, \frac 1q)\in ABCD\) and \(\frac 1p - \frac 1q = \frac{\Re \sigma}{\alpha+\beta+\gamma}\), where \(ABCD\) is the closed trapezoid with ...
