Repeated Healing Of Low Velocity Impact Induced Damage In Orthogrid-Stiffened Sandwich Panel, Patrick Mensah, Guoqiang Li, Obed Tetteh

Faculty Publications

Herein, we present a new sandwich panel composed of a carbon fiber grid-stiffened shape memory vitrimer (SMV) core. The sandwich panels were fabricated via a pin-guided dry-weaving technology, and their impact responses were evaluated via low-velocity impact testing. The main failure mode observed after the first round of impact was the transverse cracking of the SMV matrix in the sandwich core. The healing efficiency according to the crack initiation energy (CIE) was found to be 76.5% after the first healing cycle. Even after the second healing cycle, the healing efficiency was greater than 72%. From the low-velocity impact tests, reinforcing …

Self-Healing Of Macroscopic Cracks In Concrete By Cellulose Fiber Carried Microbes, Emmanuel Igbokwe, Samuel Ibekwe, Patrick Mensah, Ogad Agu, Guoqiang Li

Faculty Publications

This research introduces a new approach to healing millimeter scale cracks in concrete using Lysinibaccilus Sphaericus Bacteria (LSB) encapsulated in cellulose fibers. Cracking in concrete, particularly macroscopic cracking, can cause premature structural failure and reduce its lifespan, which is a critical industry challenge. While bacteria encapsulated in cellulose fibers have been used to heal cement mortar, the studies are limited to heal much narrower cracks. In this study, we integrate LSB, known for its strong biocalcification abilities, with the protective environment of cellulose fibers, which are renewable and sustainable, for healing millimeter scale cracks in ordinary cement concrete. To understand …

Journal of Transportation and Logistics (TRANSLOG)

In order to succeed in resolving troublesome urban transport problems, one should understand how transport demand occurs. The transport demand, which is derived demand, like the demand for a sewing machine derives from the demand for handmade clothes and the demand for marmalade derives from the demand for toast, is a result from people's need of participation in various social activities rather than the need of experiencing transportation system itself. Furthermore, travel pattern is intimately related to land use pattern, therefore instead of considering transportation and land use separately, both should be managed in parallel with each other to achieve …

Assessing The Relationship Between Contralateral Limb Synergy And Rock Climbing Efficiency, Jeromy Miramontes

Theses, Dissertations and Capstones

Rock climbing is a total body sport testing the mental and physical capabilities of athletes. Efficiency of movement can improve the ability of climbers to perform at a higher capacity and reduce the risk of injury. Data on the relationship between the continuous relative phase (CRP) of contralateral joint rotations and time to completion of a bouldering move are ways to assess rock climbing. This study aimed to assess this relationship, as well as the geometric entropy (GE) of the center of mass displacement when completing the bouldering move, and the metabolic efficiency over 4 min of bouldering.

Applying A Named Entity Recognition Model To Chemical Patents, Wanxiang Chen, Zachery Nolan, Christina Tang, Bridget T. Mcinnes

Summer REU Program

Named Entity Recognition (NER) is an application of Natural Language Processing (NLP) that involves recording entities contained in a text excerpt and classifying them into predefined category types. Unstructured text, or text without a predefined format is converted into structured text that can serve as input to an NER model. Here, we use a pretrained NER model to extract and classify chemical entities from patents/ This streamlines the process of determining the number and types of chemical agents used in a specific patent. This information may be useful for researchers, pharmaceutical companies, and agencies such as the FDA.

Inclusive Counterfactual Generation: Leveraging Llms In Identifying Online Hate, M. Atif Qureshi, Arjumand Younus, Simon Caton

Articles

Counterfactually augmented data has recently been proposed as a successful solution for socially situated NLP tasks such as hate speech detection. The chief component within the existing counterfactual data augmentation pipeline, however, involves manually flipping labels and making minimal content edits to training data. In a hate speech context, these forms of editing have been shown to still retain offensive hate speech content. Inspired by the recent success of large language models (LLMs), especially the development of ChatGPT, which have demonstrated improved language comprehension abilities, we propose an inclusivity-oriented approach to automatically generate counterfactually augmented data using LLMs. We show …

Explainable Ai For 6g Use Cases: Technical Aspects And Research Challenges, Shen Wang, M. Atif Qureshi, Luis Miralles-Pechu{\'A}N, Thien Huynh-The, Thippa Reddy Gadekallu, Madhusanka Liyanage

Articles

Around 2020, 5G began its commercialization journey, and discussions about the next-generation networks (such as 6G) emerged. Researchers predict that 6G networks will have higher bandwidth, coverage, reliability, energy efficiency, and lower latency, and will be an integrated “human-centric” network system powered by artificial intelligence (AI). This 6G network will lead to many real-time automated decisions, ranging from network resource allocation to collision avoidance for self-driving cars. However, there is a risk of losing control over decision-making due to the high-speed, data-intensive AI decision-making that may go beyond designers’ and users’ comprehension. To mitigate this risk, explainable AI (XAI) methods …

Jcati Carbon Fiber Recycler - Conveyance System, Victor Limwanich

All Undergraduate Projects

The JCATI Carbon Fiber Recycler shreds, transports, and bakes carbon fiber within its system to recycle it by burning off the resin within the material at temperatures over 500 Celsius. The conveyance portion of the recycler, as it stood in previous iterations, has not been able to transport then batch the shredded material before going into the oven. Doing so would introduce more system independence without the need for someone to manually collect the shredded batches from the conveyor belt.

After designing the project in SolidWorks to meet the objective, it was manufactured using various methods. Some parts were purchased …
