Abstract

A stator assembly that includes a graphite sheet-like element that has fold(s) so as to define at least two planar sections. The face of one of the planar section abuts a surface of a heat generating location(s) of the stator assembly and a face of another planar section abuts one the tooth or the slot bottom of the stator assembly. Also, a subassembly that includes an electrical machine stator assembly that includes a sheet-like element of a material having high thermal conductivity, wherein a portion of the element abuts the end winding(s) such that the sheet-like element conducts heat to the magnetic core, the stator housing, and/or a winding heat conduction element.

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.
