Evaluation Of Aggregate Gradation Specifications And The Feasibility Of Harmonization With Aashto Standards, Husam Elgaali, Ayesha Shah, Jan Olek
JTRP Technical Reports
The aggregate gradations specified by the Indiana Department of Transportation (INDOT) differ from those of the American Association of State Highway and Transportation Officials (AASHTO). Preliminary discussions suggest that adopting AASHTO standard gradation sizes could provide national alignment and simplify production for those operating in multiple states and supplying projects not subject to INDOT specifications. A comprehensive study was performed to evaluate the current INDOT specifications for coarse and fine aggregate gradations and to assess the potential impacts and feasibility of adopting AASHTO-specified gradations. A comparative analysis of INDOT gradations against AASHTO, ASTM International (ASTM), and those of neighboring states …

Attending To Present Others: A Framework For Supporting Multilingual Graduate Writers, María P. Carvajal Regidor, Allison Kranek
Attending To Present Others: A Framework For Supporting Multilingual Graduate Writers, María P. Carvajal Regidor, Allison Kranek
The Writing Center Journal
Extending prior work on present others, individuals who are not physically present in writing center sessions—such as advisors, colleagues, and peers—but who directly or indirectly impact what happens during consultations (Kranek & Carvajal Regidor, 2021), we argue that attending to present others is one way to more holistically support multilingual graduate writers. Based on data from session recordings, we contend that present others can be used as a framework to train consultants to better address the specific needs of this student population by acknowledging their socialization processes, feedback networks, language needs, and emotions. Then, we share two approaches to consultant …
From “Contact Zone” To “Collaborative Zone”: Multilingual Writers’ Tensions And Opportunities In The Writing Center, Qianqian Zhang-Wu, Isabelle M. Lundin, Neal Lerner
From “Contact Zone” To “Collaborative Zone”: Multilingual Writers’ Tensions And Opportunities In The Writing Center, Qianqian Zhang-Wu, Isabelle M. Lundin, Neal Lerner
The Writing Center Journal
Writing center scholars have adopted Pratt’s (1991) “contact zone” metaphor to describe the diversity of consultants and students in writing centers, but this literature has largely overlooked the perspectives of multilingual students. Through surveys, interviews, and session data, we found that while multilingual students described rich linguistic identities, they also experienced tension and instability as language users. Students often framed their considerable language assets as deficiencies in academic writing contexts. They faced additional tension between instructor expectations and their own understanding of assignment goals. Students frequently sought native-like language competency from consultants and expected them to serve as informants about …
Vibrissae-Inspired Vision-Based Magnetic-Actuated Whisker, Zhixian Hu, Yi Cheng, Juan P. Wachs, Yu She
Vibrissae-Inspired Vision-Based Magnetic-Actuated Whisker, Zhixian Hu, Yi Cheng, Juan P. Wachs, Yu She
School of Industrial Engineering Faculty Publications
Tactile perception is significant for robotic operation in unstructured environments. Whisker-based sensors offer lightweight bio-inspired solutions, yet most rely on single-whisker sensing and are limited by passive interaction and constrained functionality. Here we present a circular array of eight independently actuated whiskers, each driven by a pulse-switchable permanent magnet and tracked by a camera. This design enables simultaneous multi-point sensing and coordinated actuation, supporting diverse functions. Quantitative analyses demonstrate accurate pixel-to-physical mapping, consistent pixel-to-force characterization, and long-term repeatability. In this work, we show that an vibrissae-inspired vision-based magnetic-actuated whisker array integrating distributed perception with active interaction achieves reliable physical mapping, …

Medical Minds, Literary Voices: The Intersection Of Healing And Storytelling In Russian Literature, Emily Doris Gervais
Medical Minds, Literary Voices: The Intersection Of Healing And Storytelling In Russian Literature, Emily Doris Gervais
The Journal of Purdue Undergraduate Research
This project examines the intersection of medicine and literature through the works of Russian physicians who became influential authors. Focusing on Anton Chekhov’s Sakhalin Island, Vikenty Veresaev’s Memoirs of a Physician, and Mikhail Bulgakov’s A Young Doctor’s Notebook, this research highlights how their medical experiences shaped both their personal narratives and broader societal criticism. By analyzing the variation of both implicit, individual-centered stories and systemic, sociopolitical commentaries, the project reveals how these authors brought a unique clinical perspective to Russian literature. Their attention to detail, moral and ethical concerns, and use of medical language enriched their writings, imbuing their prose …
