The Initial Value Problem for the Equations of Magnetohydrodynamic Type in Non-Cylindrical Domain
Revista Matemática Complutense, 1995 Let \(r(t)\) be a positive-valued function of \(C^1[0, T]\), \[ Q= \{(x, t): x\in \mathbb{R}^n,\;0\leq t\leq T,\;(x)< r(t)\},\quad n= 2,3. \] The authors consider in domain \(Q\) the initial-boundary value problem \[ \begin{aligned} {\partial\overline u\over \partial t} & - {\eta\over \rho} \Delta\overline u+ (\overline u\cdot \nabla) \overline u- {\mu\

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Maximal regular boundary value problems in Banach-valued function spaces and applications
International Journal of Mathematics and Mathematical Sciences, 2006 The nonlocal boundary value problems for differential operator equations of second order with dependent coefficients are studied. The principal parts of the differential operators generated by these problems are non-selfadjoint.

Computational fluid dynamics model for a variable conductance thermosyphon
Case Studies in Thermal Engineering, 2021 A variable conductance thermosyphon is a unique type of heat pipe that responds passively to changes in thermal environment because of the presence of non-condensable gas (NCG).

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Measurement of the transient shielding effectiveness of enclosures using UWB pulses inside an open TEM waveguide [PDF]
Advances in Radio Science, 2007 Recently, new definitions of shielding effectiveness (SE) for high-frequency and transient electromagnetic fields were introduced by Klinkenbusch (2005). Numerical results were shown for closed as well as for non closed cylindrical shields.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.
