Abstract

Critical electronics used for isotopes production have become outdated and difficult to manufacture. In particular the alpha-particle and neutron detection electronics (commonly referred to as Q2809A-9 and -11) which are used to monitor effluent activity in ORNL Building 7920 were designed and deployed in 1966-67. These electronics are still used but some parts are no longer available for purchase. In addition, the printed circuit boards used in the Count Rate Monitor (CRM) module have no fabrication files or quality assurance documentation. In light of this, a project to modernize the modules for ability to manufacture with modern parts was undertaken. Both the preamplifier and CRM were modernized with new printed circuit boards and parts which are current catalog parts. In addition, QA documentation was generated which allows the manufacturer to assure proper operation prior to delivery.

Large language models for transportation research: Methodologies, state of the art, and future opportunities

The rapid rise of large language models (LLMs) is transforming transportation research, with significant advancements emerging between 2023 and 2025, a period marked by the inception and swift growth of adopting and adapting LLMs for various transportation applications. Despite these significant advancements, however, a systematic review and synthesis of the existing literature remains lacking. This paper aims to fill this gap by providing a comprehensive review of the methodologies and applications of LLMs in transportation. We explore key applications, including autonomous driving, travel behavior prediction, and general transportation-related queries, alongside LLM methodologies such as zero- or few-shot learning, prompt engineering, and fine-tuning. From the review, critical research gaps are identified. From the methodological perspective, many of the research limitations can be addressed by integrating LLMs with existing tools and refining LLM architectures. From the application perspective, research opportunities for LLMs to address various transportation challenges are also explored. By synthesizing these findings, this review not only presents the state-of-the-art LLM adoption and adaptation in transportation, but also proposes future research directions as well as insights and recommendations for policymakers and practitioners, paving the way for greater LLM-driven research innovations in transportation in the future.
