1. 36. Rigid Body Ship Dynamics

   Författare :Martin Alexandersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse dynamics; Extended Kalman filter; Ship digital twin; Ship manoeuvring; RTS smoother; Multicollinearity; System identification;

   Sammanfattning : It is common today that operational data is recorded onboard ships within the Internet of Ships (IoS) paradigm. This enables the possibility to build ship digital twins as digital copies of the real ships. Predicting the ship’s motions with ship dynamics could be an important sub-component of these ship digital twins. LÄS MER

3. 37. Computational Insights on Functional Materials for Clean Energy Storage : Modeling, Structure and Thermodynamics

   Författare :Tanveer Hussain; Rajeev Ahuja; Caetano R. Miranda; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Density functional theory; Molecular dynamics; Hydrogen storage; Chemisorption; Physisorption; Functionalization; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : The exponential increase in the demands of world’s energy and the devastating effects of current fossil fuels based sources has forced us to reduce our dependence on the current sources as well as finding cleaner, cheaper and renewable alternates. Being abundant, efficient and renewable, hydrogen can be opted as the best possible replacement of the diminishing and harmful fossil fuels. LÄS MER

4. 38. Population and Community Dynamics in Variable Environments

   Författare :Jörgen Ripa; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dispersal; Moran effect; linear dynamics; synchrony; power spectrum; autocorrelation; extinction risk; population dynamics; environmental stochasticity; migration; stochastic modelling; Ecology; Ekologi;

   Sammanfattning : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. LÄS MER

5. 39. Dynamics of Disordered Materials in Confined Geometries

   Författare :Christer Svanberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer film; glass transition; confinement; polymer gel; dynamics; dielectric spectroscopy; gel electrolytes; relaxation; photon correlation; cooperativity;

   Sammanfattning : This thesis is concerned with effects of geometrical confinement on dynamics in disordered materials in the nanoscopic range. Of particular interest is the dynamics around the liquid to glass transition. Two systems have been investigated: thin polymer films and polymer gels. LÄS MER

7. 40. Modelling the Structural Dynamics of Business Networks : Two Agent-based Models of Supply Networks

   Författare :Sara Shahin Moghadam; Frans Prenkert; Franziska Klügl; Magnus Hansson; Davide Secchi; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business networks; dynamics; Agent-based modelling; structural change; responses; interactions; complex adaptive systems;

   Sammanfattning : This thesis aims at describing and analysing the structural changes of business networks that emerge as a result of change triggers. Despite previous studies, our understanding of the evolution of the network structure and its influencing factors is still limited. LÄS MER
