1. 11. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study

   University essay from Linköpings universitet/Fordonssystem

   Author : Björn Kleman; Henrik Lindgren; [2021]
   Keywords : model-based; fault diagnosis; neural networks; data-driven; Hybrid; SCR; exhaust gas treatment system; recurrent neural networks; grey-box; heavy duty truck; fault isolation; fault detection; diagnosis; urea; machine learning; Scania; structural model; MSO; residual; Fault Diagnosis Toolbox;

   Abstract : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. READ MORE

3. 12. Grey Box Model of Leakage In Radial Piston Hydraulic Motors

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Niklas Ydebäck; [2021]
   Keywords : Grey box; modeling; Radial piston; Bosch Rexroth; parameter estimation;

   Abstract : This report covers the work and results of the thesis project in Mechanical Engineering from Luleå university of technology performed by Niklas Ydebäck. The objective of the thesis project is to research if it is possible, with general principles of fluid flow between components and the corresponding geometric constraints between them and just a few channels of data, to model the leakage of a radial piston hydraulic motor.

4. 13. Development of grey-box models for simulating heating consumption in buildings : A study applying system identification methodology to a physics-based framework

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Zack Klockar; [2021]
   Keywords : System identification; heating; buildings; modelling; insulation; empirical modelling; ARX; OE; time-series; simulation; energy consumption; grey-box; black-box;

   Abstract : This study models the energy used for heating in buildings by applying system identification methodology. The model development is grounded in physics to provide guidance and interpretability when evaluated. Time-series of heating demand, outdoor temperature, indoor temperature and solar irradiation are considered for the modelling purpose. READ MORE

5. 14. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Jacob Wallersköld; Johan Appelros; [2021]
   Keywords : wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

   Abstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE

6. 15. Secure IPC to Enable Highly Sensitive Communication in a Smartphone Environment with a BYOD Setup

   University essay from Linköpings universitet/Informationskodning
