Topology design optimization of conductive thermal problems subject to design-dependent load using density gradients

Advances in Mechanical Engineering, 2019
In this article, a design sensitivity analysis method is developed for topology optimization of steady-state conductive thermal problems subject to design-dependent thermal loads using density gradients–based boundary detection.

Large Anomalous and Topological Hall Effect and Nernst Effect in a Dirac Kagome Magnet Fe3Ge

Advanced Functional Materials, EarlyView.
Fe3Ge, a Kagome‐lattice magnet, exhibits remarkable anomalous Hall and Nernst effects, with transverse thermoelectric conductivity surpassing or comaprable to some well‐known ferromagnets. First‐principles calculations attribute these to Berry curvature from massive Dirac gaps. Additionally, topological Hall and Nernst signals emerge from field‐induced

Exploring Landmark Placement Strategies for Topology-Based Localization in Wireless Sensor Networks

EURASIP Journal on Advances in Signal Processing, 2008
In topology-based localization, each node in a network computes its hop-count distance to a finite number of reference nodes, or “landmarks”.

Electroactive Metal–Organic Frameworks for Electrocatalysis

Advanced Functional Materials, EarlyView.
Electrocatalysis is crucial in sustainable energy conversion as it enables efficient chemical transformations. The review discusses how metal–organic frameworks can revolutionize this field by offering tailorable structures and active site tunability, enabling efficient and selective electrocatalytic processes.

From Becker-Döring to Lifshitz-Slyozov: deriving the non-local boundary condition of a non-linear transport equation

ITM Web of Conferences, 2015
We investigate the connection between two classical models of phase transition phenomena, the (discrete size, Markov chain or infinite set of ODE) Becker-Döring equations and the (continuous size, PDE) Lifshitz-Slyozov equation.

Fine topology, Šilov boundary, and (ddc)n

Journal of Functional Analysis, 1987
The authors study the following: In section 2, they give a short discussion of the (pluri-) fine topology of plurisubharmonic (psh) functions. In section 3, they consider the problem: if \(\psi\) is a bounded, fine continuous function with compact support, then \(\int \psi (dd^ cu_ j)^ n\to \int \psi (dd^ cu)^ n,\) where \(u_ j\) is a uniformly bounded

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...

Design of multiple materials structure based on an explicit and implicit hybrid topology optimization method

Scientific Reports
In this paper, an explicit and implicit hybrid topology optimization method is proposed for the design of multiple materials structure. The explicit topology optimization employs the moving morphable component (MMC) method to determine where the solid ...
