2. 1. Integration of database technology and multibody system analysis

   Author : Claes Tisell; KTH; []
   Keywords : machine element; dynamic systems; multibody system kanes equations of motion; simulation; submodel; functional assembly;

   Abstract : The design process includes many different activities inwhich various computational mechanics tools are used forbehaviour modelling of mechanical systems and their buildingblocks, e.g. machine elements. These tools usually supportlarge and complex models and they produce large quantities ofdata with a high degree of complexity. READ MORE

4. 2. Some results on closed-loop identification of quadcopters

   Author : Du Ho; Martin Enqvist; Gustaf Hendeby; Alexander Medvedev; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In recent years, the quadcopter has become a popular platform both in research activities and in industrial development. Its success is due to its increased performance and capabilities, where modeling and control synthesis play essential roles. READ MORE

5. 3. Conceptual Runoff Models for Material Transport Estimations

   Author : Rikard Lidén; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; Conceptual Rainfall-Runoff Modelling; Riverine Material Transport; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Abstract : Catchment-scale material transport models are today important tools for water and environmental management. However, modelling of material transport is extremely complex due to the physical, chemical and biological processes involved. READ MORE

6. 4. Design and Implementation of Object-Oriented Model Libraries using Modelica

   Author : Hubertus Tummescheit; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling languages; thermo-fluid systems; process modeling; process control; control systems; thermo-hydraulic systems; non-linear models; model library design; object-oriented; modeling; simulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This thesis describes basic models for thermo-fluid systems and the implementation of the models using a flexible object-oriented structure in the ThermoFluid library. Model libraries provide an excellent way to package engineering knowledge of systems to be reused by non-experts. READ MORE

7. 5. Dynamics of forest soil chemistry

   Author : Mattias Alveteg; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; critical loads; regional; recovery; acidification; modelling; SAFE; MAKEDEP; Kemiteknik och kemisk teknologi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Abstract : Acidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.
