Doctoral school I & Midterm meeting

February 1, 2021 - February 8, 2021

Due to the covid19 pandemic, the first Doctoral School and the Midterm meeting will be held online during the first week of February 2021. Despite its name, the Midterm meeting with the REA Project Officer is held on February 4, 2021 as an one day event. Both events will be held on Zoom, links are emailed to the participants. Please join the meeting using your full name!

Meeting with the REA Project Officer: schedule and its cialis substitute over the counter

Friday, February 5th, 2021 (Chair: G. Muntingh)
11:00 Tutorial [Part A]: Maria Salamó (UB): Point-cloud analysis and classical Machine Learning techniques
Abstract: The analysis of point cloud has been done in different ways in the field of machine learning. This tutorial is devoted to introducing the main machine learning algorithms that can be used for point-cloud analysis, among other applications. It has been divided in two parts. First part is focused on the theoretical aspects of classical machine learning algorithms, while the second part is devoted to deep learning algorithms. In both parts, the theoretical foundations of every type of algorithm will be detailed. We will see practical examples of 3D shapes analysis on every part.

11:00 Tutorial [Part A]: Alexander Leutgeb (RISC-Software): Dynamic Cutting Force Prediction (During Simulation of Machining Processes) (Chair: A. Fabri)
Abstract: The problem domain is to predict the cutting forces during simulation of metal cutting processes. There already exist several force computation models. These models have in common, that for different material combinations (cutting tool and workpiece) the determination of their coefficients is a time consuming task by performing different metal cutting patterns with the real machine and measuring the resulting cutting forces over the time. The novel approach of our research project should learn this coefficients from regular machining processes. That means we need on the one hand the data from the simulation (machining parameters and geometric representation of cutter workpiece engagement) and on the other hand the measured forces of the sensors from the real machine. Because usually the real machines do not come with sensors providing force measurements we will use an Internet-of-Things sensor from Pro Micron, which measures the forces directly on the tool side. So from a Machine Learning standpoint we have to first correlate the time series data from the simulation with that of the sensor. Later on we perform model fitting/regression (linear & non linear) to learn the coefficients for the force computation model.
After the model is trained, the simulation of the machining process can predict the cutting forces over the time. The application of these forces is relevant for machine vibration analysis, feed rate optimization, increase of energy efficiency, geometric errors in finished workpieces caused by tool cutter deflections, and so on.

14:00 Tutorial [Part B]: Christoph Hofer (RISC-Software): Dynamic Cutting Force Prediction (During Simulation of Machining Processes) (Chair: A. Fabri)
15:00 Coffee break
17:00 Seminar: Managing and sharing research outputs: all you need to knowSLIDES & VIDEO
Presenters: Elli Papadopoulou, Athena RC/ OpenAIRE, Iryna Kuchma, Electronic Information for Libraries – eifl / OpenAIRE
Abstract: This is an introductory session to the Open Science model. It aims to ensure that all ESRs have a comprehensive understanding of the basics of Open Science and are able to apply them in their everyday work using available resources. Presentations will highlight good practices in scientific publishing and data management activities that increase researchers recognition and at the same time achieve compliance with European requirements (e.g. grants received under H2020, HorizonEurope and ERC). A “first-aid toolkit” will be provided so that researchers can practice Open Science skills at their own time and pace.
18:15 End of the Doctoral School

Schedule of the Midterm Meeting (February 4th, 2021)

The purpose of the Midterm meeting between the REA Project Officer (Filippo Galiardi) and the Consortium is as to discuss the implementation of the project, make sure that all ESRs have been recruited and review the rules of the Marie Curie programme to see if there are any issues that need to be addressed before the beginning of the scientific activities. All beneficiaries and ESRs should participate the meeting. Our Partner Organisations are strongly encouraged to participate.
