Pre-meeting stakeholders’ reports

New H2020 project involving digital twins (called PROBONO) has just been granted with Carl Schultz as the ECE/AU PI

Created a “new_model” branch for VDMCheck and converted “fmi2” checker to use generated XSD/VDM schema. Currently testing.
Looked at some native VDM/Java models for Ken Pierce (student support work)
Cleaned up VDMJ for nested comment LB decisions, and ported change over to Overture.
Prepared VDMJ for the next VSCode release, to include Hugo’s stdlib changes.

Found a nice Python library for visualizing robots (a number of robot arm models exist, but other models can possibly be added using URDf files), packaged it into an FMU and tested it in into-cps. It works on windows, and on Mac Mojave, but not on Mac Catalina (Got help fom Gita to test it on Mac). But this could be a direction to work towards in the future, if we want to do visualizations for co-simulations using python FMUs.

Overture
- vs-code Add Library feature added to vs-code vdm extension. Working on the coverage now. Established communication between client and server. Need to work on show covtab files.
- Worked on camera-ready paper and video on the SLSP protocol to be presented at F-IDE workshop soon.
- Planning to write a paper on this to Overture WS.
INTO-CPS Application
- RC is out for testing purposes try it here
DT for Water
- Preparing a talk on DT to present in the evanet thematic day on DT
- Looking for students interested in exploring recently open Data Sets about urban water networks

Coding setup for connecting matlab and the FMI interface, for co-simulation of civil engineering structures, using uniFMU.
Coding reference FMUs for synchronous clock.

DTP is off the table, as DIGITBrain is target the same. Will focus on individual modules for maestro2 addressing different things.
Kenneth is working on multi-threaded support for maestro2
Frederik has worked on lots of stuff - lastly a derivativeestimator module for maestro2 (from maestro1)
Started handoff of maestro2 release to Prasad
Working with Gita and Henrik on RabbitmqFMU papers
Meeting with Henrik on Chrono FMU, and will have meeting with Frederik Foldager
Msestro2 paper

Working the rabbitmq development and papers with Henrik and Casper
Discussed possibility of adding a configurable delay compensator in the rabbitMQ FMU
Working on the scenarios for the ARF projects

Robot Dynamics Calibration:
- Added cross-validation and performance visualization of estimation and validation dataets separately
- Working on adding Weighted Least Squares (WLS) calibration as an alternative to the current Ordinary Least Squares (OLS) calibration
