CTRC Research Publications
The two-dimensional laser-based Ångstrom method measures the in-plane thermal properties for anisotropic film-like materials. It involves periodic laser heating at the center of a suspended film sample and records its transient thermal response by infrared imaging. These spatiotemporal temperature data must be analyzed to extract the unknown thermal conductivity values in the orthotropic directions, an inverse parameter fitting problem. Previous demonstration of the metrology technique used a least-squares fitting method that relies on numerical differentiation to evaluate the second-order partial derivatives in the differential equation describing transient conduction in the physical system. This fitting approach is susceptible to measurement noise, …

Needs Assessment – National Repository For Nsf Agep Deliverables, Christie Sahley, Megan Sapp-Nelson, Donna Ferullo, Linda Mason, Hanzi Xie
Libraries Faculty and Staff Scholarship and Research
This white paper proposes the establishment of a National Repository for NSF Alliance for Graduate Education and the Professoriate (AGEP) Deliverables to address the critical need for preserving and sharing a wide array of materials generated from the AGEP program. Recognizing the challenges of ephemeral storage solutions and the absence of a unified collection mechanism, the paper underscores the repository's role in promoting justice, equity, diversity, and inclusion (JEDI) research. It emphasizes the importance of accommodating diverse data types, enhancing discoverability, and ensuring long-term access to educational materials, policy documents, and research outcomes. Through a comprehensive approach, the proposed repository …

Business Archives As A Tool For Academic Business Researchers, Annette Bochenek, Ilana Stonebraker
Libraries Faculty and Staff Scholarship and Research
This paper examines the structure and collections in business archives in order to create a list of suggestions to better prepare researchers seeking historical business data prior to 1970. Four business archivists were chosen for interviews from a variety of industries. The article shares seven tips gained from the interviews, including getting to know what is housed or not housed in the business archive, looking for archives with museum arms, and considering the importance of legal permission as part of the process for utilizing business archives. The authors also explore how business librarians can better support the work of business …
Tracking Information In The Field: An Assessment Of The Information Needs And Services Of A Field Station Library, Thom Gerrish, Scott Martin
Tracking Information In The Field: An Assessment Of The Information Needs And Services Of A Field Station Library, Thom Gerrish, Scott Martin
Libraries Faculty and Staff Scholarship and Research
This project examines field station libraries, an undescribed type of library associated with terrestrial and marine field stations. Field stations typically support ecology, geology, and related disciplines with housing, laboratories, and research facilities, which may include various levels of library support. In summer 2022, researchers, instructors, and staff at the University of Michigan Biological Station were interviewed about the library resources and services they use while working and teaching at the field station. Library resources were used throughout teaching and research activities, with one-shot instruction and in-person reference support as the primary contact points between the library and the field …
Leto: Learning Constrained Visuomotor Policy With Differentiable Trajectory Optimization, Zhengtong Xu, Yu She
Leto: Learning Constrained Visuomotor Policy With Differentiable Trajectory Optimization, Zhengtong Xu, Yu She
School of Industrial Engineering Faculty Publications
This paper introduces LeTO, a method for learning constrained visuomotor policy with differentiable trajectory optimization. Our approach integrates a differentiable optimization layer into the neural network. By formulating the optimization layer as a trajectory optimization problem, we enable the model to end-to-end generate actions in a safe and constraint-controlled fashion without extra modules. Our method allows for the introduction of constraint information during the training process, thereby balancing the training objectives of satisfying constraints, smoothing the trajectories, and minimizing errors with demonstrations. This “gray box” method marries optimization-based safety and interpretability with powerful representational abilities of neural networks. We quantitatively …
