Seminars /Workshops / Events

nanoHUB is excited to announce the next workshop 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 that participants will be able to incorporate in their own work. Hands-on activities will use nanoHUB cloud computing resources, negating the need to download or install any software. All that is required of the audience is an internet connection and an hour to spare for the demonstration. 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
Please register soon as seats are limited. Share with any colleagues who may be interested.
Title: A Machine Learning aided hierarchical screening strategy for materials discovery
Date: July 21st, 2021, 1:30 PM - 2:30 PM EST
Speaker: Anjana Talapatra, Postdoctoral Fellow, Los Alamos National Laboratory
Register here (limited seats): https://nanohub.org/groups/ml/handsontraining
Abstract: One of the most basic approaches to problem solving is to conceptualize the problem at different abstraction levels and translate from one abstraction level to the others easily, i.e., deal with them hierarchically. This concept is especially applicable to the field of novel materials discovery, wherein large candidate domains can be quickly and efficiently explored by hierarchically discarding irrelevant candidates. In this tutorial, we illustrate this approach using the example of wide band gap oxide perovskites. We will sequentially search a very large domain space of single and double oxide perovskites to identify candidates that are likely to be formable, thermodynamically stable, exhibit insulator nature and have a wide band gap. To this end, we will build four machine learning (ML) models: three classification and one regression model using experimental and DFT-calculated training data. The tutorial will discuss best practices for building ML models, commonly encountered pitfalls and how best to avoid them.

Purchasing Catalog Updates

In an effort to provide the best quality and value for campus customers, Procurement Services has named Fastenal, Ferguson/HP and Kirby Risk as the preferred suppliers for Maintenance Repair Operations (MRO) products.  Updated Ariba catalogs with these preferred suppliers and negotiated pricing are now available. These strategic partners were selected during a robust solicitation process to help meet the University's need for various supplies, including cleaning, safety, HVAC, plumbing, electrical, and general MRO hardware.

A breakdown of the supplies and the new preferred vendors is as follows:

  *   Cleaning supplies - Ferguson/HP
  *   Electrical supplies - Kirby Risk
  *   General MRO hardware supplies - Ferguson/HP
  *   HVAC supplies - Fastenal
  *   Plumbing supplies - Ferguson/HP
  *   Safety supplies - Fastenal

Purchases that would have previously gone through any of the below providers should now be submitted

through one of the above catalog suppliers.

  *   Duncan Supply
  *   Grainger
  *   Graybar Electric
  *   Interline Brands
  *   McMaster Carr
  *   Motion Industries
  *   MSC
  *   Newark Electronics

Additionally, Office Depot is now Purdue's preferred supplier for computer accessories and peripherals<https://www.purdue.edu/procurement/purchasing/catalog-orders/computers-equipment.php>.  The Ariba catalog has been updated with discounted pricing for these products and is currently available for purchase under Office Depot. These purchases were previously supported by GovConnection.

The Fisher Scientific catalog<https://www.purdue.edu/procurement/purchasing/catalog-orders/laboratory-supplies.php> has also been updated to include Qiagen and Sigma-Aldrich products. All new or updated catalogs are available in Ariba, and the previously used supplier catalogs have been removed. If an item previously purchased cannot be purchased from one of the current catalogs, a non-catalog order<https://www.purdue.edu/procurement/purchasing/non-catalog-orders/index.php> may be submitted for the item.  Contact information for these suppliers can be found on the Procurement Services website<https://www.purdue.edu/procurement/purchasing/catalog-orders/index.php>.
