Abstract excerpt
A developed reacting-air solution is transferred to an unchanged, 41,962,496-hexahedron domain through an admissibility-checked continuation method. Seven species, two thermal energies, and shear-stress-transport turbulence are coupled through thermodynamic, acoustic, charged-transport, and nonlinear-update equations.

Abstract excerpt
We present a System Entity Structure methodology for orchestrating large language model agents as a Discrete Event System Specification coupled model, with verification and validation carried out through the DEVS hierarchy of system specifications and its morphisms.

Abstract excerpt
Artificial intelligence (AI) for systems engineering has evolved through six paradigms in five decades: expert systems, machine learning, deep learning, large language models, agentic AI, and agentic swarms, with each paradigm shorter than the last.

Abstract excerpt
The digital thread remains fragmented in practice: requirements, architectures, models, and verification evidence are exchanged through documents and manual reconciliation rather than machine-verifiable relationships, and Modeling & Simulation (M&S) therefore functions as a downstream report about the system rather than the system's authoritative executable representation.

Abstract excerpt
We present a four-arc progressive assessment system with a geospatial common operational picture (COP), developed during the IGNITE '26 hackathon (March 16–19, 2026).

Abstract excerpt
The convergence of three quantum computing milestones in twelve months has compressed the post-quantum cryptography (PQC) migration timeline from a next-decade concern to a present-day operational imperative.

Abstract excerpt
Commercial frontier AI advances through a global system of computation, research, software development and feedback. Deploying a model inside a defense network does not reproduce the system that continually advances its capability.

Abstract excerpt
Bernard P. Zeigler established a rigorous systems foundation for model-based intelligent agents. With his collaborators, he developed architectures in which agents use internal representations to plan actions, monitor consequences, coordinate with other agents, and recover when execution departs from expectations.

Overview
Philipbar Analytics LLC’s Artificial Intelligence for Gaming, Exercise, Modeling & Simulation (PALLC AI-GEMS) applies PALLC’s expertise in the Advanced Framework for Simulation, Integration and Modeling (AFSIM), Joint Simulation Environment (JSE), Next Generation Threat System (NGTS), and heterogeneous co-simulation to a common integration problem: preserving temporal event synchronization across independently developed models and simulators.
