The Internet of Things for Smart Manufacturing: A Review
Hui Yang, Soundar Kumara, Satish Bukkapatnam +1
The modern manufacturing industry is investing in new technologies such as the Internet of Things (IoT), big data analytics, cloud computing and cybersecurity to cope with system c…
EBLIME: Enhanced Bayesian Local Interpretable Model-agnostic Explanations
Yuhao Zhong, Anirban Bhattacharya, Satish Bukkapatnam
We propose EBLIME to explain black-box machine learning models and obtain the distribution of feature importance using Bayesian ridge regression models. We provide mathematical exp…
Unsupervised spectral-band feature identification for optimal process discrimination
Akash Tiwari, Satish Bukkapatnam
Changes in real-world dynamic processes are often described in terms of differences in energies of a set of spectral-bands . Given continuous…
Hypothesis Tests with Functional Data for Surface Quality Change Detection in Surface Finishing Processes
Shilan Jin, Rui Tuo, Akash Tiwari +5
This work is concerned with providing a principled decision process for stopping or tool-changing in a surface finishing process. The decision process is supposed to work for produ…
Towards Futuristic Autonomous Experimentation--A Surprise-Reacting Sequential Experiment Policy
Imtiaz Ahmed, Satish Bukkapatnam, Bhaskar Botcha +1
An autonomous experimentation platform in manufacturing is supposedly capable of conducting a sequential search for finding suitable manufacturing conditions by itself or even for…
Ripple formation and its effect on the multi-scale microstructure of Directed Energy Deposition (DED)-printed 316L components
Himanshu Balhara, Bhaskar Botcha, Sarah Wolff +1
An experimental study is presented to characterize the ripple formations in the directed energy deposition (DED) process and study the influence of the ripples on the heterogenous…
A Review of the Anomalies in Directed Energy Deposition (DED) Processes and Potential Solutions
Michael Liu, Abhishek Kumar, Satish Bukkapatnam +1
Directed Energy Deposition (DED) processes offer one of the most versatile current techniques to additively manufacture and repair metallic components that have generatively design…
Towards Non-Contact Glucose Sensing in Aqueous Turbid Medium at ~1.1 Meters Distance
Daqing Piao, John O'Hara, Satish Bukkapatnam +1
This work demonstrates a non-contact diffuse reflectance approach with a working distance of ~1.1 meters for the potential of glucose sensing. Non-contact diffuse reflectance over…
Artificial neural network to estimate the refractive index of a liquid infiltrating a chiral sculptured thin film
Patrick D. McAtee, Satish T. S. Bukkapatnam, Akhlesh Lakhtakia
We theoretically expanded the capabilities of optical sensing based on surface plasmon resonance in a prism-coupled configuration by incorporating artificial neural networks (ANNs)…
Simultaneous 12-Lead Electrocardiogram Synthesis using a Single-Lead ECG Signal: Application to Handheld ECG Devices
Kahkashan Afrin, Parikshit Verma, Sanjay S. Srivatsa +1
Recent introduction of wearable single-lead ECG devices of diverse configurations has caught the intrigue of the medical community. While these devices provide a highly affordable…
Consistent estimation of the max-flow problem: Towards unsupervised image segmentation
Ashif Sikandar Iquebal, Satish Bukkapatnam
Advances in the image-based diagnostics of complex biological and manufacturing processes have brought unsupervised image segmentation to the forefront of enabling automated, on th…
Balanced Random Survival Forests for Extremely Unbalanced, Right Censored Data
Kahkashan Afrin, Gurudev Illangovan, Sanjay S. Srivatsa +1
Accuracies of survival models for life expectancy prediction as well as critical-care applications are significantly compromised due to the sparsity of samples and extreme imbalanc…
Change detection in complex dynamical systems using intrinsic phase and amplitude synchronization
Ashif Sikandar Iquebal, Satish Bukkapatnam, Arun Srinivasa
We present an approach for the detection of sharp change points (short-lived and persistent) in nonlinear and nonstationary dynamic systems under high levels of noise by tracking t…
Surface plastic flow in polishing of rough surfaces
Ashif S. Iquebal, Dinakar Sagapuram, Satish Bukkapatnam
We report electron microscopy observations of the surface plastic flow in polishing of rough metal surfaces with a controlled spherical asperity structure. We show that asperity--a…
