Stochastic PDEs and Infinite Horizon Backward Doubly Stochastic Differential Equations

open access: yesJournal of Applied Mathematics, 2012
We give a sufficient condition on the coefficients of a class of infinite horizon BDSDEs, under which the infinite horizon BDSDEs have a unique solution for any given square integrable terminal values.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Almost Surely Exponential Stability of Numerical Solutions for Stochastic Pantograph Equations

open access: yesAbstract and Applied Analysis, 2014
Our effort is to develop a criterion on almost surely exponential stability of numerical solution to stochastic pantograph differential equations, with the help of the discrete semimartingale convergence theorem and the technique used in stable analysis ...

Double barrier reflected BSDEs with stochastic Lipschitz coefficient

open access: yesModern Stochastics: Theory and Applications, 2017
This paper proves the existence and uniqueness of a solution to doubly reflected backward stochastic differential equations where the coefficient is stochastic Lipschitz, by means of the penalization method.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

open access: yesAdvanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

Multi-valued backward stochastic differential equations with regime switching

open access: yesAdvances in Difference Equations, 2019
The paper considers a class of multi-valued backward stochastic differential equations with subdifferential of a lower semi-continuous convex function with regime switching, whose generator is a continuous-time Markov chain with a finite state space ...

Linear Forward—Backward Stochastic Differential Equations [PDF]

open access: yesApplied Mathematics and Optimization, 1999
Theorems are proved establishing conditions for the solvability of a system of coupled linear forward-backward stochastic differential equations of the form \[ dX(t)= \bigl\{AX(t)+BY(t) +CZ(t)+Db(t)\bigr\}dt +\bigl \{A_1X(t) +B_1Y(t)+ C_1Z(t)+ D_1\sigma (t)\bigr\}dW(t), \] \[ dY(t)= \bigl\{ \widehat AX(t)+ \widehat BY(t)+ \widehat CZ(t)+ \widehat D ...

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
