We integrated existing AI and data research lifecycles into an eight-stage I-GUIDE Research Lifecycle, serving …
Evaluating The Evaluation Matrices: Integrating Spatial Assessment In Geospatial Ai Model Training And Evaluation, Fangzheng Lyu
Evaluating The Evaluation Matrices: Integrating Spatial Assessment In Geospatial Ai Model Training And Evaluation, Fangzheng Lyu
I-GUIDE Forum
This paper examines the limitations of current evaluation metrics in GeoAI. Through two case studies on deep learning models—a building detection classification problem and a remote sensing image fusion regression problem—this paper demonstrates how traditional statistical evaluation matrices alone can be misleading in geospatial problems. The findings indicate that traditional metrics (e.g., RMSE, MAE) used in current GeoAI models can have difficulty capturing the spatial dimensions inherent to geospatial problems. This paper suggests that the model evaluation process in GeoAI should move beyond traditional evaluation matrices by integrating spatial thinking throughout the modeling pipeline—not only incorporating spatial accuracy in model …

Selective Anti-Tumor And Normal Tissue Sparing Effects Of Flash Radiotherapy In A Simple Algebraic Model Of Radiochemical Kinetics, Charles F. Babbs
Selective Anti-Tumor And Normal Tissue Sparing Effects Of Flash Radiotherapy In A Simple Algebraic Model Of Radiochemical Kinetics, Charles F. Babbs
Weldon School of Biomedical Engineering Faculty Working Papers
Background: This short paper presents the solution to an open problem in medical physics: how and when FLASH radiotherapy can have a selective anti-tumor effect. FLASH radiotherapy gives a single large dose of ionizing radiation to a cancer patient within a time span of a few milliseconds, unlike conventional radiotherapy which is divided into several dose fractions given weekly, each lasting about 10 minutes. In some animal models FLASH seems to improve tumor cell killing without damaging normal tissues. However, the mechanism of the selective anti-tumor effect remains elusive. Methods: To explore effects of tissue hypoxia in tumors, a model …

The Lesson Of Confucius For Today’S America: Education In Ethics Is The Road To Building A Just And Peaceful Society, Yeomin Yoon
The Lesson Of Confucius For Today’S America: Education In Ethics Is The Road To Building A Just And Peaceful Society, Yeomin Yoon
KAUPA Letters
According to Confucius, what confers humans their special status and dignity among beings in nature is the moral virtues they can achieve. Humans should build good character, for which they need education to acquire values. He found no correlation between the ability to learn and the socio-economic status. He believed that people with the ability to learn deserved an opportunity to learn. Confucius would not approve of the prevalent American conception of education as transmitting technical knowledge and skills to students without an education in the values to promote by their use. Purely technical education would be an oxymoron for …

Beyond Core Object Recognition: Dnns As Models Of Dynamic Scene Perception, Matthias Tangemann, Matthias Kümmerer, Matthias Bethge
Beyond Core Object Recognition: Dnns As Models Of Dynamic Scene Perception, Matthias Tangemann, Matthias Kümmerer, Matthias Bethge
MODVIS Workshop
Deep neural networks (DNNs) have become influential computational models of human vision, particularly in explaining neural responses in the ventral stream. However, they frequently diverge from well-established findings in psychophysics, especially with regard to human perceptual biases, robustness, and generalization behavior. Much of the progress in aligning DNNs with human perception has focused on the task of core object recognition—the rapid identification of objects in static images (DiCarlo et al., 2012). In contrast, other critical dimensions of visual perception, such as motion processing and multi-object scene understanding, remain comparatively underexplored. In this talk, I present our recent work on modeling …
Bell Telephone System’S Preeminent Role In The Growth Of Industrial Design, Ralph O. Meyer, Russell A. Flinchum
Bell Telephone System’S Preeminent Role In The Growth Of Industrial Design, Ralph O. Meyer, Russell A. Flinchum
Purdue University Press Books
Histories of design pay scant attention to the corded telephone, which played an immeasurable role in early communication. Although the Bell System, with many Nobel Prizes, is justly acknowledged for its technical prowess, it should also be recognized for its early and considerable impact on the developing discipline of industrial design. In 1930, young Henry Dreyfuss, who would later become known as a pioneer of industrial design, was retained by the Bell System as a design consultant and matured in that environment. With substantial input from Bell System engineers, Dreyfuss and his staff produced attractive telephone designs that were manufactured …

In-Hand Singulation, Scooping, And Cable Untangling With A 5-Dof Tactile-Reactive Gripper, Yuhao Zhou, Pokuang Zhou, Shaoxiong Wang, Yu She
School of Industrial Engineering Faculty Publications
Manipulation tasks often require a high degree of dexterity, typically necessitating grippers with multiple degrees of freedom (DOF). While a robotic hand equipped with multiple fingers can execute precise and intricate manipulation tasks, the inherent redundancy stemming from its high-DOF often adds complexity that may not be required. In this paper, we introduce the design of a tactile sensor-equipped gripper with two fingers and five-DOF. We present a novel design integrating a GelSight tactile sensor, enhancing sensing capabilities and enabling finer control during specific manipulation tasks. To evaluate the gripper's performance, we conduct experiments involving three challenging tasks: 1) retrieving, …

Demonstration Of A Digital Twin Framework For A Two-Actuator Hydraulic Application, Marvin R. Durango -Cogollo, Jose M. Garcia-Bravo
Purdue Polytechnic Graduate Student Poster Symposium
This project presents a digital twin framework for controlling a hydraulic crane using AI, mixed reality, and real-time actuation. Leveraging a Jetson Nano and Xbox Kinect for perception and a Raspberry Pi with DRV103 for control, the system enables adaptive motion planning and obstacle-aware navigation. A Unity-based interface integrated with HoloLens2 allows operators to visualize and manipulate the crane through FABRIK inverse kinematics. Real-time environmental mapping from Kinect enables obstacle detection to update the motion path dynamically. Early experiments confirm the ability to compute joint angles in real-time, detect environmental objects, and demonstrate closed-loop control in a virtual-physical hybrid system.
