Exact observability of a 1D wave equation on a non-cylindrical domain
, 2017 We discuss admissibility and exact observability estimates of boundary observation and interior point observation of a one-dimensional wave equation on a time dependent domain for sufficiently regular boundary functions. We also discuss moving observers inside the non-cylindrical domain and simultaneous observability results.

On the Exact Boundary Control for the Linear Klein-Gordon Equation in Non-cylindrical Domains
TEMA (São Carlos), 2020 The purpose of this paper is to study an exact boundary controllability problem in noncylindrical domains for the linear Klein-Gordon equation. Here, we work near of the extension techniques presented By J. Lagnese in [12] which is based in the Russell’s controllability method.

Advanced Functional Materials, EarlyView.Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites
Advanced Functional Materials, EarlyView.Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

The Karlsruhe Dynamo Experiment [PDF]
Nonlinear Processes in Geophysics, 2002 It has been shown theoretically in the past that homogeneous dynamos may occur in electrically conducting fluids for various vortical velocity fields. Roberts (1972) investigated spatially periodic, infinitely extended fields of vortices which Busse (

On the Navier-Stokes equations in non-cylindrical domains: On the existence and regularity
Mathematische Zeitschrift, 1988 We consider the motion of a viscous incompressible fluid in a container with moving walls, in other words we have to deal not with a space-time cylinder but with a non-cylinder domain in \({\mathbb{R}}^ 3\times [0,T]\). To be more precise, we consider a domain \[ \Omega_ T=\cup_{0\leq t\leq T}\Omega (t)x\{t\}, \] where each \(\Omega\) (t) is a bounded ...
