Constructing Difference: Maternal Boundary‐Work in Science‐Based and Natural Mom Groups on Facebook

Symbolic Interaction, EarlyView.
Boundary‐work describes the activities of social groups as they seek to differentiate themselves from others to establish credibility, authority, or to protect their interests. While a growing body of literature explores occupational boundary‐work in health care, limited research has focused on how lay actors practice boundary‐work online.

High-Accuracy Radar Parameter Estimation Under Low SNR Environments

IEEE Access
This paper proposes a high-accuracy radar parameter estimation method for extremely low signal-to-noise ratio (SNR) environments, integrating deep learning and connected component analysis (CCA). Accurate estimation of parameters such as time of arrival,

Balancing Accuracy and Cost: Trade‐Offs in Large Language Model Quantization for the Systems Engineering Domain

Systems Engineering, EarlyView.
ABSTRACT As Large Language Models (LLMs) are increasingly deployed within the systems engineering domain, optimizing these models to balance performance accuracy and cost for given computational resources becomes essential. One process for finding the right balance is quantization, a process that involves converting model parameters from higher ...

Baselining Large Language Model Performance in Systems Engineering Using SysEngBench

Systems Engineering, EarlyView.
ABSTRACT In the rapidly evolving field of artificial intelligence (AI), large language model s (LLMs) have demonstrated impressive capabilities in generating natural language. However, their proficiency in specialized domains, particularly in the field of systems engineering (SE), remains less explored and unquantified.

Assessment of a Model‐Based Approach to Achieve Authorization to Operate

Systems Engineering, EarlyView.
ABSTRACT Accreditation of United States Government (USG) Information Systems (IS) is required to assure their function and security before delivery to the operational environment. However, in many cases, the baseline document‐based accreditation processes are sources of cost and schedule overruns.

Alignment of Agile and Modular Open Systems Approach (MOSA) Principles in Systems Engineering

Systems Engineering, EarlyView.
ABSTRACT Organizations have consistently sought faster and more efficient methods for producing and delivering products. Agile principles offer essential guidance for shaping their policies and practices. The Agile Manifesto (AM) outlines 12 core principles for guiding software development but can also be applied in other contexts.

Impacts of Change‐Type and State‐Type System Qualities on Complex System Architectures

Systems Engineering, EarlyView.
ABSTRACT System qualities, such as scalability, expandability, and reconfigurability, are key requirements of complex systems. Requirements associated with system qualities are important factors in design trade space analyses, but systems engineering design methodologies make only limited use of these qualities, hindering a holistic understanding of ...

Accelerating Mission Engineering: Evidence of a Stratified Landscape and a Path Toward Unified Practice

Systems Engineering, EarlyView.
ABSTRACT Mission Engineering is maturing as a Systems Engineering discipline, yet adoption of its common frameworks remains stratified. This study examines whether selective adoption is observable across ME scholarship and develops a framework to address identified barriers.
