Second DCS PhD Spotlight session 2022
The Dutch Chemometrics Society (DCS) is excited to announce the second DCS PhD Spotlight session, in which the presentations will be related to NIR data analysis.
The second session will be held on May 12th (Thursday) from 12:30-13:30.
Program:
- Talk 1: Predicting the performance of handheld near-infrared sensors from a master benchtop device, by Mark Schoot (Radboud University Nijmegen, NutriControl Analytical Solutions)
-
Many industries see a shifting focus towards performing on-site analysis using handheld spectroscopic devices. Myriad handheld solutions with very different specifications and pricing are available on the market. Although specifications are generally available for new devices, this does not directly quantify or predict how available devices will perform for targeted cases. We present a novel chemometric method to estimate the prediction performance of handheld NIR hardware and apply it to estimate the performance of two commercially available handheld NIR technologies in predicting protein content in pig feed from existing data of a benchtop device. Our method utilizes information on the error structure of the handheld devices for the estimation. It yielded performance estimates differing less than 1 g kg-1 from the experimentally determined handheld performances and similar model parameters. Our method was effective for linear and nonlinear calibration algorithms, also when estimating performance after averaging multiple scans. Overall, our method provides estimates of the performance of a handheld device for a specific task with minimal testing required and can thus be used as a device or application screening tool before committing to develop calibrations.

- Material Fingerprinting in the Mining industry – Clustering of VNIR–SWIR and geochemistry data, by Jeroen van Duijvenbode (Delft University of Technology)
-
Within the mining industry, a lot of spectral and geochemical data is collected from rock samples to indicate the properties of the different styles of mineralization in an orebody. The quantity of these data increases rapidly during the daily operations of a mine since every one-meter composite sample is tested. This presentation will focus on interpreting these large (combined >250,000 samples) multivariate datasets using compositional data analysis, principal component analysis and clustering in two parts. The first part will focus on VNIR-SWIR data and the second part combines this with the geochemical data. Commonly, VNIR-SWIR data are analyzed by extracting specific absorption features, however, this way, not all potential value is extracted from the spectral responses, as will be shown. In this study, we clustered spectral range values and, using this found a new spectral feature region related to epidote not recognized before. Furthermore, within a spatial contextual relationship, it was found that this epidote feature also relates to the rock hardness, which is important during the crushing and grinding of rocks to extract gold.

The session will be streamed online via Zoom platform, will last around 1 hour, and is free of charge. You do not need to register for this event. The Zoom link will be shared the same day of the event via e-mail to all those who are subscribed to the Dutch Chemometrics Society mailing list. You can subscribe to the DCS mailing list here.
If you are a PhD student and want to present your work or if you are PhD supervisor and you think one of your student may be interested feel free to send us an email at
We hope you will join and help us put PhD students in the Spotlight again!
More about the DCS PhD Spotlight sessions
As a consequence of the Covid pandemic, most of the scientific conferences and events have followed a short online format with few keynote talks in the program. While this has still allowed professionals and renowned scientific speakers to share their research, PhD students had less opportunities to present their work and get valuable feedback from the scientific community during their first steps in academia.
As it will still take some time to get back to the pre-pandemic situation in international traveling and face to face events, The Dutch Chemometrics Society would like to provide PhD students a platform to share their research around Chemometrics and related disciplines.
For this reason we are excited to announce the new DCS PhD Spotlight sessions, a series of free online seminars where PhD students will present their work.

DCS Masterclass on Data Visualization
November 12, 2019
Bar Beton, Utrecht Central Station
The Netherlands
The Dutch Chemometrics Society (DCS) cordially invites you to a DCS Masterclass on Data Visualization! The Masterclass will feature two renown plenary speakers from the data visualization field: Casper Albers and Sara Sprinkhuizen.
Casper is a professor at Rijksuniversiteit Groningen in applied statistics and data visualization. His research focuses on statistical modelling of psychological processes, applied in clinical psychology and environmental psychology and on the interplay between statistics and science communication. He has over 50 peer reviewed papers, has given numerous lectures and workshops and occasionally writes scientific columns for Dutch newspaper De Volkskrant. Casper will mainly speak about a theoretical basis for multivariate data visualization (e.g. biplots).
Sara is a freelance data analyst and data visualization expert. After having studied physics, she got intrigued by data visualization because proper data visualization can strongly contribute to get complex messages across. She is currently active as data analyst, data visualizer and consultant for multiple international companies and research institutes, including MIT Media Lab, the online newspaper De Correspondent, the Dutch medical journal Nederlands Tijdschrift voor Geneeskunde, and the Màxima Medical Center in Eindhoven. Sara's talk will mainly focus on perceptional and aesthetic aspects of data visualization.
Two experts in data science and chemometrics will challenge the talks to trigger discussion. Renger Jellema (senior scientist at DSM Biotechnology Center, The Netherlands) and José Camacho (Associate Professor in the Department of Signal Theory, Networking and Communications at University of Granada, Spain) will take up the challenger role.
Date, time, location
The Masterclass will be held on November 12, 2019 at Bar Beton in Utrecht. Bar Beton is conveniently located at Utrecht Central Station and can thus be very easily reached by public transport. The masterclass starts at 09.30 hrs and ends at 16.00 hrs, followed by some drinks and snacks.
