Seminars /Workshops / Events

nanoHUB is excited to announce the first two workshops in the Summer 2021 session of our Hands-on Data Science and Machine Learning Training Series.

Series information. Our series is aimed at active researchers and educators and designed to introduce practical skills with online, hands-on activities participnts

will be able to incorporate in their work. Hands-on activities will use nanoHUB cloud computing resources, no need to download or install any software. All you

need is an internet connection and a browser. After the training sessions, you will be able to continue using nanoHUB for research or education.

Registration links and material for prior workshops can be found at the workshop webpage: https://nanohub.org/groups/ml/handsontraining Register soon as seats are limited.

Title: A Hands-on Introduction to Physics-Informed Neural Networks
Date: May 26th 2021,  1:30 PM - 2:30 PM EST
Speaker: Ilias Bilionis, Purdue University

Register here (limited seats): https://nanohub.org/groups/ml/handsontraining

Abstract: Can you make a neural network satisfy a physical law? There are two main types of these laws: symmetries and ordinary/partial differential equations. I will focus on differential equations in this short presentation. The simplest way to bake information about a differential equation with neural networks is to create a regularization term for the loss function used in training. I will explain the mathematics of this idea. I will also talk about applying physics-informed neural networks to a plethora of applications spanning the range from solving differential equations for all possible parameters in one sweep (e.g., solve for all boundary conditions) to calibrating differential equations using data to design optimization. Then, we will work on a hands-on activity that shows you to implement the ideas in PyTorch. I am assuming some familiarity with how conventional neural networks are trained (stochastic gradient descent). Also, you need to know the basics of PyTorch to follow along. Going over this tutorial should be sufficient: https://pytorch.org/tutorials/beginner/pytorch_with_examples.html.

Title: Batch Reification Fusion Optimization (BAREFOOT) Framework
Date:  June 2nd 2021,  1:30 PM - 2:30 PM EST
Speaker: Richard Couperthwaite, Texas A&M University

Register here (limited seats): https://nanohub.org/groups/ml/handsontraining

Abstract: This tutorial will present the fundamentals of multi-fidelity fusion as well as Sequential and Batch Bayesian Optimization as possible optimization approaches that can be integrated with high accuracy computational models or experimental procedures to speed up the optimization or design of materials. The tutorial will also provide an overview of the BAREFOOT framework that combines these two approaches together to further improve the rate of the optimization. All these approaches are compared using the optimization of the workability of a dual-phase steel microstructure.

RA Position at Birck
SEM training and assistance:
The Birck Nanotechnology Center is looking for a Grad student with experience in scanning electron microscopy to assist 20 hrs a week with the SEMs at BNC - Hitachi S4800 FESEM and TFS Apreo FESEM  in the clean room.
The responsibilities will be:

  *   Provide SEM analysis services - imaging and EDX chemical analysis - to BNC and industrial  users using both the Hitachi S4800 and TFS Apreo FE-SEM
  *   Manage the reception of samples and analysis instructions from Birck users
  *   Training new users in both the SEMs Hitachi S-4800 and TFS Apreo
  *   Align the microscopes biweekly and make sure the systems are working properly.
  *   Provide assistance to users remotely in case an issue arises.
  *   Manage the training and services request for both SEMs in Ilab and provide metrics every week.
  *   Training new users in SPI sputter coater, Nanomill ion polisher, and mechanical polisher.
  *   Have great disposition, excellent communication skills, and ability to solve problems when providing services or trainings

Birck Equipment Training

Training and equipment repair are the two top priorities for Birck staff members.  Training queues have been increasing lately due to new users coming to Birck and current researchers sometimes expanding their project scope.  We're anticipating an influx of additional new users over the Summer and into the Fall semester so we are considering a number of actions to help us become more efficient in providing user trainings.  Among these ideas are.....

  1.  Increasing the number of users being trained from 1 to 2, as appropriate.  This is being considered on a case-by-case basis taking into account the requirement to maintain a COVID-safe training experience.
  2.  Supplementing our SOPs with video overviews as we can get them developed.
  3.  Providing more pre-work online prior to the in-person training.
  4.  Coordinating training timing to better match when the users need to first use the tools.

Thanks for your support of our efforts, and we would be happy to hear other ideas you have to make our training process more efficient.
