HEMI Short Course – OpenMSI: Data streaming for autonomous laboratory research

Autonomous laboratories are poised to revolutionize research in materials, pharmaceuticals, biology, and other fields. Autonomous experiments combine robotic automation with AI/ML decision making and control. Data streaming — moving data automatically from the instruments where it is collected to storage and compute services —is a core technology for autonomous research because it allows data to be accessed, processed, and acted on in real time. For current (non-autonomous) labs, streaming can vastly improve data throughput, consistency, and reliability.

HEMI Short Course – OpenMSI: Data streaming for autonomous laboratory research

This HEMI short course will introduce students to OpenMSIStream, a new cross-platform tool for streaming and sharing among data-producing and data-consuming devices. Participants will learn how to:

  • Install OpenMSIStream on their own computer (Windows, macOS, or Linux)
  • Stream actual instrument readings in real time to remote storage
  • Access streamed data
  • Set up automated processes to analyze and act on the data.

Students will leave the short course with the skills necessary to implement OpenMSIStream to stream and process data in their own labs to create new functionality, enable automated workflows, and participate in development of forward-looking, autonomous research paradigms.

This event is intended for students and postdocs who are interested in autonomous experimental research. Seating is limited. Those interested in participating will be able to sign up for a waitlist once capacity has been reached.

HEMI/MSEE Impact Research Workshop & Short Course

Johns Hopkins University’s Hopkins Extreme Materials Institute (HEMI), in collaboration with the Materials Science in Extreme Environments (MSEE) University Research Alliance, will host a workshop and short course on impact research experiments in July 2023. This event is being organized by a committee from Johns Hopkins including: Prof. Ryan Hurley, Prof. Mark Foster, Prof. Todd Hufnagel, Mr. Justin Moreno, Prof. KT Ramesh, and Mr. Matt Shaeffer. The emphasis of the event will be on impact research experiments performed using gas guns, powder guns, and electromagnetic launchers.

The three-day workshop will provide an overview of the fundamental physics and mechanics associated with impact research experiments. The emphasis of the workshop will be on lecture-style presentations introducing the fundamentals of shock wave propagation, material response to impact, and modeling approaches. The target audience of the workshop is graduate students, postdocs, and applied researchers entering the field of impact research experiments, and DoD program managers seeking learning and networking opportunities. The workshop will also feature a select number of keynotes highlighting the state-of-the-art in experiments, material behavior, and modeling, and by program managers describing DoD interests, needs, and hiring opportunities in these areas. Finally, the workshop will feature poster and networking sessions for students, postdocs, applied researchers, and faculty to interact with one another and with DoD program managers. Workshop participation is limited to 50 individuals.

The two-day short course (REGISTRATION IS FULL) will provide participants with an opportunity for hands-on setup and execution of a gas gun experiment in HEMI’s Hypervelocity Facility for Impact Research Experiments (HyFIRE). On day 1, a specific experiment and research objective will be presented. Students will aid in timing calculations, setup and synchronization of diagnostics, and experiment execution. Data will be shared with students for basic analysis on the day 2. Short course participation is limited to 15 individuals selected through our application process.

Registration Deadline: Uncertainty Quantification Short Course

Instructor: Dr. Sankaran Mahadevan (John R. Murray Sr. Professor of Engineering Professor of Civil and Environmental Engineering, Professor of Mechanical Engineering Director, NSF-IGERT Doctoral Program in Reliability and Risk Engineering and Management Co-Director, Laboratory for System Integrity and Reliability Vanderbilt University)

Location: Johns Hopkins University, Homewood Campus, Baltimore, MD

About the course: Model-based simulation is attractive for the performance and reliability analysis of structural and material systems under extreme conditions, since full-scale testing is often unaffordable. However, model-based simulation involves many approximations and assumptions, and thus confidence in the simulation result is an important consideration in risk-informed decision-making. Sources of uncertainty are both aleatory and epistemic, stemming from natural variability, information uncertainty, and modeling approximations at multiple levels. Information uncertainty arises from sparse and imprecise data, measurement and data processing errors, and qualitative information. Model uncertainty arises due to unknown model parameters, model form assumptions, and solution approximation errors. This short course will present recent methods for the quantification of uncertainty from multiple sources, and their aggregation towards the behavior prediction of multi-physics, multi-scale systems. Multiple activities such as calibration, verification and validation are conducted as part of the model development at multiple levels, and methods to integrate the results of these activities will be presented. In a multi-scale modeling environment, the information available is heterogeneous, from multiple sources (models, tests, experts) and in multiple formats. The use of Bayesian networks to integrate heterogeneous information will be presented. An important objective of uncertainty quantification is uncertainty reduction. Different analyses and tests at different levels of fidelity could be performed, offering trade-offs between accuracy and cost; thus resource allocation strategies for different uncertainty quantification activities will be outlined, and their effect on uncertainty reduction will be discussed.
