A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Cost-Based Filtering Techniques for Stochastic Inventory Control Under Service Level Constraints [PDF]

open access: yes, 2009
This paper considers a single product and a single stocking locationproduction/inventory control problem given a non-stationary stochastic demand.Under a widely-used control policy for this type of inventory system, the objectiveis to find the optimal ...

On the Optimality of State-Dependent Base-Stock Policies for an Inventory System with PH-Type Disruptions

open access: yesLogistics
Background: The management of inventory under realistic supply chain disruptions, which are often non-exponential, challenges classical control theory.

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.

Construction of an Optimal Strategy: An Analytic Insight Through Path Integral Control Driven by a McKean–Vlasov Opinion Dynamics

open access: yesMathematics
In this paper, we have constructed a closed-form optimal strategy within a social network using stochastic McKean–Vlasov dynamics. Each agent independently minimizes their dynamic cost functional, driven by stochastic differential opinion dynamics. These

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

On one-dimensional stochastic control problems: applications to investment models [PDF]

open access: yes, 2008
The paper provides a systematic way for finding a partial differential equation that characterize directly the optimal control, in the framework of one?dimensional stochastic control problems of Mayer, with no constraints on the controls.

Formal model of a cognitive-evolutionary cloud architecture with memory reconfiguration and optimization

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики"
Cloud orchestration systems, such as Borg, Kubernetes, and AIOps platforms, excel at scaling and anomaly detection. However, they typically optimize within a fixed architecture rather than over it.

Stochastic Controllability of Systems with Multiple Delays in Control [PDF]

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2009
Stochastic Controllability of Systems with Multiple Delays in ControlFinite-dimensional stationary dynamic control systems described by linear stochastic ordinary differential state equations with multiple point delays in control are considered. Using the notation, theorems and methods used for deterministic controllability problems for linear dynamic ...

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.
