Data-Driven Ergonomic Risk Assessment of Complex Hand-intensive Manufacturing Processes

no code implementations5 Mar 2024 Anand Krishnan, Xingjian Yang, Utsav Seth, Jonathan M. Jeyachandran, Jonathan Y. Ahn, Richard Gardner, Samuel F. Pedigo, Adriana, Blom-Schieber, Ashis G. Banerjee, Krithika Manohar

We develop a data-driven ergonomic risk assessment system with a special focus on hand and finger activity to better identify and address ergonomic issues related to hand-intensive manufacturing processes.

Statistical Mechanics of Dynamical System Identification

no code implementations4 Mar 2024 Andrei A. Klishin, Joseph Bakarji, J. Nathan Kutz, Krithika Manohar

Recovering dynamical equations from observed noisy data is the central challenge of system identification.

Data-Induced Interactions of Sparse Sensors

no code implementations21 Jul 2023 Andrei A. Klishin, J. Nathan Kutz, Krithika Manohar

Because of this structure, we can use just a few spatially localized sensor measurements to reconstruct the full state of a complex system.

Constrained optimization of sensor placement for nuclear digital twins

no code implementations23 Jun 2023 Niharika Karnik, Mohammad G. Abdo, Carlos E. Estrada Perez, Jun Soo Yoo, Joshua J. Cogliati, Richard S. Skifton, Pattrick Calderoni, Steven L. Brunton, Krithika Manohar

Strategically placing sensors within defined spatial constraints is essential for the reconstruction of reactor flow fields and the creation of nuclear digital twins.

Data-Driven Aerospace Engineering: Reframing the Industry with Machine Learning

no code implementations24 Aug 2020 Steven L. Brunton, J. Nathan Kutz, Krithika Manohar, Aleksandr Y. Aravkin, Kristi Morgansen, Jennifer Klemisch, Nicholas Goebel, James Buttrick, Jeffrey Poskin, Agnes Blom-Schieber, Thomas Hogan, Darren McDonald

Indeed, emerging methods in machine learning may be thought of as data-driven optimization techniques that are ideal for high-dimensional, non-convex, and constrained, multi-objective optimization problems, and that improve with increasing volumes of data.

Kernel Analog Forecasting: Multiscale Test Problems

no code implementations13 May 2020 Dmitry Burov, Dimitrios Giannakis, Krithika Manohar, Andrew Stuart

The nature of the predictions made, and the manner in which they should be interpreted, depends crucially on the extent to which the variables chosen for prediction are Markovian, or approximately Markovian.

Sparse Principal Component Analysis via Variable Projection

no code implementations1 Apr 2018 N. Benjamin Erichson, Peng Zheng, Krithika Manohar, Steven L. Brunton, J. Nathan Kutz, Aleksandr Y. Aravkin

Sparse principal component analysis (SPCA) has emerged as a powerful technique for modern data analysis, providing improved interpretation of low-rank structures by identifying localized spatial structures in the data and disambiguating between distinct time scales.

Optimized Sampling for Multiscale Dynamics

no code implementations14 Dec 2017 Krithika Manohar, Eurika Kaiser, Steven L. Brunton, J. Nathan Kutz

The multiresolution DMD is capable of characterizing nonlinear dynamical systems in an equation-free manner by recursively decomposing the state of the system into low-rank spatial modes and their temporal Fourier dynamics.

Predicting shim gaps in aircraft assembly with machine learning and sparse sensing

no code implementations24 Nov 2017 Krithika Manohar, Thomas Hogan, Jim Buttrick, Ashis G. Banerjee, J. Nathan Kutz, Steven L. Brunton

This new approach is based on the assumption that patterns exist in shim distributions across aircraft, which may be mined and used to reduce the burden of data collection and processing in future aircraft.
