1. 1. Relationship between Shear-Wave Velocity and Consolidation Parameters of Peat

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

   Författare :Oskar Markström; [2018]
   Nyckelord :shear wave velocity; peat; constant rate of strain; consolidation parameters; von Post; Technology and Engineering;

   Sammanfattning : There is a need of developing methods for evaluating material parameters for peat. It is hard and costly to obtain undisturbed samples for laboratory testing of the peat. Therefore, in this thesis the possibility of using in situ measurements of the shear wave velocity for first order estimates of the consolidation parameters has been investigated. LÄS MER

3. 2. Estimation of Ship Properties for Energy Efficient Automation

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Lucas Nilsson; [2016]
   Nyckelord :System identification; ship properties; energy efficient; automation; ship modelling; estimation; signal processing; simulation; ship dynamics; cusum; cumulative summation; change in dynamics; load condition; podded propulsion; azipod; yaw dynamics; noise impact; measurement noise; model error; bias due to model error; ship yaw model; moment of inertia; estimate ship properties; ship automation;

   Sammanfattning : One method to increase efficiency, robustness and accuracy of automatic control, is to introduce mathematical models of the system in question to increase performance. With these models, it is possible to predict the behavior of the system, which enables control according to the predictions. LÄS MER
