Reactivity in the theory of the stationary nuclear fission wave

Ядерна фізика та енергетика, 2016
We studied axial motion of the stationary nuclear fission wave in the cylindrical core of the traveling wave reactor (known also as CANDLE) using an effective one-dimensional model of the fast spectrum reactor with uranium plutonium fuel.

Two-stage linear-nonlinear shaping of an optical frequency comb as rogue nonlinear-Schrödinger-equation-solution generator

, 2014
We report a wave generator of complex solutions of the nonlinear Schrodinger equation (NLSE) combining both intensity and phase spectral shaping of an initial optical frequency comb with subsequent nonlinear propagation in an optical fiber.

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

Advanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Three-Dimensional Complex Padé FD Migration: Splitting and Corrections

International Journal of Geophysics, 2012
Three-dimensional wave-equation migration techniques are still quite expensive because of the huge matrices that need to be inverted. Several techniques have been proposed to reduce this cost by splitting the full 3D problem into a sequence of 2D ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

A software perspective on infinite elements for wave diffraction and wave forces on marine risers [PDF]

, 2000
This thesis describes work on the problem of the scattering of water waves by fixed objects. The method used to solve this problem is that of finite and infinite elements. In particular the development of a new wave infinite element is described. Various

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells

Advanced Functional Materials, EarlyView.
Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Illumination and Resolution Analyses on Marine Seismic Data Acquisitions by the Adjoint Wavefield Method

Terrestrial, Atmospheric and Oceanic Sciences, 2012
We applied a wave-equation based adjoint wavefield method for seismic illumination and resolution analyses. A two-way wave-equation is used to calculate directional and diffracted energy fluxes for waves propagating between sources and receivers to the ...

Stability and wave motion problems in continuous media with second sound [PDF]

, 2009
In this thesis we investigate thermal convection and wave motion in models of second sound such as the Cattaneo model, Green and Laws model, Batra model, and Green and Naghdi model. For the Green and Laws and Batra models we also investigate questions of
