Dynamic Obstacle Avoidance For Usvs Using Cross-Domain Deep Reinforcement Learning And Neural Network Model Predictive Controller, Jianwen Li, Jalil Chavez-Galaviz, Kamyar Azizzadenesheli, Nina Mahmoudian
Purdue University Libraries Open Access Publishing Fund
This work presents a framework that allows Unmanned Surface Vehicles (USVs) to avoid dynamic obstacles through initial training on an Unmanned Ground Vehicle (UGV) and cross-domain retraining on a USV. This is achieved by integrating a Deep Reinforcement Learning (DRL) agent that generates high-level control commands and leveraging a neural network based model predictive controller (NN-MPC) to reach target waypoints and reject disturbances. A Deep Q Network (DQN) utilized in this framework is trained in a ground environment using a Turtlebot robot and retrained in a water environment using the BREAM USV in the Gazebo simulator to avoid dynamic obstacles. …

Mhealth Hyperspectral Learning For Instantaneous Spatiospectral Imaging Of Hemodynamics, Yuhyun Ji, Sang Mok Park, Semin Kwon, Jung Woo Leem, Vidhya Vijayakrishnan Nair, Yunjie Tong, Young L. Kim
Purdue University Libraries Open Access Publishing Fund
Hyperspectral imaging acquires data in both the spatial and frequency domains to offer abundant physical or biological information. However, conventional hyperspectral imaging has intrinsic limitations of bulky instruments, slow data acquisition rate, and spatiospectral trade-off. Here we introduce hyperspectral learning for snapshot hyperspectral imaging in which sampled hyperspectral data in a small subarea are incorporated into a learning algorithm to recover the hypercube. Hyperspectral learning exploits the idea that a photograph is more than merely a picture and contains detailed spectral information. A small sampling of hyperspectral data enables spectrally informed learning to recover a hypercube from a red–green–blue (RGB) …

People and Animals: The International Journal of Research and Practice
With the proliferation of canine-assisted interventions and the emphasis placed on the impact of these sessions in bolstering the well-being of visitors to sessions, especially university students, it can be easy to overlook just how participating in one of these sessions is experienced by participants. Capturing participants’ experiences is important as this holds the potential to inform program design and delivery and elucidate mechanisms within the intervention that were found to be especially efficacious. Forging new empirical terrain, this study explored the insights and perceptions of 469 undergraduate students who participated in a virtual canine-assisted stress-reduction intervention at a mid-size …
Emotional Depictions Of Dogs And Cats In Interactions With Humans In Picture Books, Juri Nakagawa, Naoko Koda
Emotional Depictions Of Dogs And Cats In Interactions With Humans In Picture Books, Juri Nakagawa, Naoko Koda
People and Animals: The International Journal of Research and Practice
This study quantitatively analyzed the depiction of dogs’ and cats’ emotions in picture books and discussed the effects on children’s recognition of real dog and cat emotions. The stories depicted many basic emotional depictions of interest, joy, and surprise in dogs and cats, whereas the humans in the stories showed more varied, complicated emotions. Interest was most often caused by familiar humans in dogs, and by objects in cats. Joy was most often caused by familiar humans in dogs and cats, which would lead child readers to recognize that dogs and cats are friendly toward humans. There were depictions of …

School of Engineering Education Faculty Publications
Self-report assessments are used frequently in higher education to assess a variety of constructs, including attitudes, opinions, knowledge, and competence. Systems thinking is an example of one competence often measured using self-report assessments where individuals answer several questions about their perceptions of their own skills, habits, or daily decisions. In this study, we define systems thinking as the ability to see the world as a complex interconnected system where different parts can influence each other, and the interrelationships determine system outcomes. An alternative, less-common, assessment approach is to measure skills directly by providing a scenario about an unstructured problem and …

Purdue University Libraries Open Access Publishing Fund
Existing reaction transition state (TS) databases are comparatively small and lack chemical diversity. Here, this data gap has been addressed using the concept of a graphically-defined model reaction to comprehensively characterize a reaction space associated with C, H, O, and N containing molecules with up to 10 heavy (non-hydrogen) atoms. The resulting dataset is composed of 176,992 organic reactions possessing at least one validated TS, activation energy, heat of reaction, reactant and product geometries, frequencies, and atom-mapping. For 33,032 reactions, more than one TS was discovered by conformational sampling, allowing conformational errors in TS prediction to be assessed. Data is …

Reducing Construction Change Orders With 3d Cim Technology, John Langmaid, Aaron Bubb, Sammy Van Pelt
Purdue Road School
As long as 2D paper plans are the construction contract document, 3D Civil Information Management (CIM) technology will improve bid-ability, constructability, and overall plan quality. The CIM process leverages modeling technology to reverse engineer 2D plans and build the project electronically prior to letting. Used with engineering best practices, CIM identifies plan errors, conflicts, and other challenges which ultimately reduce construction change orders. Featured projects will include I-69 in Bloomington and the Ohio River Bridges.

Value-Added Geotechnical Solutions At A Peat Bog, Mike Wigger, Kevin Hetrick, Joann Woolridge
Value-Added Geotechnical Solutions At A Peat Bog, Mike Wigger, Kevin Hetrick, Joann Woolridge
Purdue Road School
SR 26 at CR 200E in Blackford County was constructed over a 40-ft deep peat bog. Continual settlement had been a challenge, leading to substandard vertical curves and drainage issues. Geotechnical analysis and hydraulic modeling in conjunction with county input and cooperation resulted in a unique culvert mat foundation requiring little profile grade-raise on SR 26. The design decisions resulted in project delivery of less than half of INDOT’s budget and a significantly reduced life-cycle cost.
