Numerical Simulation of Transient Heat Conduction With Moving Heat Source Using Physics Informed Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this article, the physics informed neural networks (PINNs) is employed for the numerical simulation of heat transfer involving a moving source under mixed boundary conditions. To reduce computational effort and increase accuracy, a new training method is proposed that uses a continuous time‐stepping through transfer learning.

Inspection Game With Imperfect Detection Technology

Naval Research Logistics (NRL), EarlyView.
ABSTRACT In this article, we investigate a generalized two‐player inspection game between an attacker and a defender who allocates multiple resources across a critical system. Specifically, the attacker targets components of the system while the defender coordinates multiple inspection units to monitor disjoint subsets of components and detect attacks.

Solving Large‐Scale Weapon Target Assignment Problems in Seconds Using Branch‐Price‐And‐Cut

Naval Research Logistics (NRL), EarlyView.
ABSTRACT This paper proposes a framework based on branch‐price‐and‐cut to solve the weapon target assignment (WTA) problem, a popular class of non‐linear assignment problems that has received significant attention over the past several decades. We first reformulate the WTA into a form amenable to column generation and then derive efficient algorithms ...

Mission Abort Policy Considering Imperfect Alarms and Two Abort Options

Naval Research Logistics (NRL), EarlyView.
ABSTRACT A mission may be aborted during operation to increase the likelihood of system survival when an alarm system indicates that the system has entered a defect state. However, due to measurement and environmental noise, missed and false alarms frequently occur during online condition monitoring, complicating the decision‐making process for mission

Abundant Neighborhoods, Two‐Sided Markets, and Maximal Matchings

Naval Research Logistics (NRL), EarlyView.
ABSTRACT I introduce a new graph‐theoretic property called abundant neighborhoods. This property is motivated by studying the thickness of economic markets. A vertex is, roughly, guaranteed to match if and only if it has an abundant neighborhood.
