SLIDE SETS under Materials
Remote usage of Aalto's workstations
Check the page and possibilities, if you find it interesting:

https://www.aalto.fi/en/it-for-students (ENG) -> Remote Work
If this works / (does not) ->let us know!
The main idea for the course realization is that the "contact teaching" will be in TEAMS:
Separate TEAMS links for the
- lectures
- simulations
- lectures (Tuesdays at 16.15 o'clock) -> Join Microsoft Teams Meeting- simulation sessions (6 official sessions, starting on 7.10.2020, on Wednesdays at 16.15. o'clock) -> Join Microsoft Teams Meeting
"See you" on Tuesday!
................................................
Please, follow the Coronavirus situation and its effects on courses:
https://into.aalto.fi/display/enopisk/Coronavirus+-+information+for+students
General idea for this Systems course is that we have the possibility for remote learning by using TEAMS or corresponding platform.
However, we will follow the instructions given by the university!
If you will use your own computer during the course ...
Install
- Mathcad (possibly free Mathcad Express)
- Matlab + Simulink with Simscape toolbox (https://download.aalto.fi/index-en.html)
Brief introduction to the "latest development" in Hydraulics
https://www.youtube.com/watch?v=uYIzWI12T8g&t=6s
The Topics this yerar cover "energy efficient hydraulic system".
On our list we have for example ...
- Load Sensing systems - calculations and simulations
- Direct Drive Hydraulics (DDH or EHA) - calculations and simulations
- modern architectures (e.g. Multipressure system)
More information to come!
