1. 1. Kinematic Enrolment in Four Ordovician Trilobites Using Three-Dimensional Modelling

   University essay from Uppsala universitet/Paleobiologi

   Author : Alejandro Corrales Garcia; [2023]
   Keywords : 3D modelling; Blender; Dysplanus centrotus; enrolment kinematics; Gyrometopus lineatus; Illaenus sarsi; Ordovician; trilobites; Trilobiter; Enrollering; 3D-modellering; Blender; Modelos 3D; Blender; cinematica; enrollamiento; Ordovicico; trilobites;

   Abstract : Trilobites were a successful group of marine arthropods that thrived for much of the Palaeozoic Era. Akey innovation of trilobites involved the capacity to enrol their biomineralized exoskeletons for protection; a trait that appeared early in their evolutionary history during the Cambrian Period.

3. 2. Spatial Statistical Modelling of Insurance Claim Frequency

   University essay from Lunds universitet/Matematisk statistik

   Author : Daniel Faller; [2022]
   Keywords : Insurance risk; claim frequency; Markov chain Monte Carlo MCMC ; Riemann manifold Metropolis adjusted Langevin algorithm MMALA ; spatial statistics; Gaussian Markov random field GMRF ; preconditioned Crank Nicolson Langevin algorithm pCNL ; Gibbs sampling; Bayesian hierarchical modelling; high dimensional; shrinkage prior; horseshoe prior; regularisation.; Mathematics and Statistics;

   Abstract : In this thesis a fully Bayesian hierarchical model that estimates the number of aggregated insurance claims per year for non-life insurances is constructed using Markov chain Monte Carlo based inference with Riemannian Langevin diffusion. Some versions of the model incorporate a spatial effect, viewed as the relative spatial insurance risk that originates from a policyholder's geographical location and where the relative spatial insurance risk is modelled as a continuous spatial field.

4. 3. Discontinuous Galerkin Method for Liquid Chromatography Modelling

   University essay from Umeå universitet/Institutionen för fysik

   Author : Sara Culligan; [2022]
   Keywords : ;

   Abstract : Chromatography is a separation technique used predominantly by the medical industry in purification and extraction of components in a solution. The setup is a column filled with resin particles where a solution of two components is filtered and separated due to different rates of interaction with the resin particles. READ MORE

5. 4. Measuring T1 using MP2RAGE in Human Brain at 7T – Effect of B1+ and Inversion Pulse Efficiency

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Mustafa Kadhim; [2021]
   Keywords : Medicine and Health Sciences;

   Abstract : Introduction: The MP2RAGE technique has become popular for structural MRI at ultra-high fields. The core idea behind MP2RAGE is to reduce the influence of flip angle inhomogeneity (B +), proton density and T2* by calculating the regularized signed ratio of two complex MP-RAGE images acquired at different inversion times (TI) within the cycle.

6. 5. Modelling and Dynamic Performance of Hydropower in Frequency Regulation : Modelling of Double Regulated Hydropower Turbines

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Kristinn Arnar Ormsson; [2021]
   Keywords : Frequency Containment Reserves FCR ; Hydropower; Double regulated DR turbine; Non-linear modelling; Simulink.; Frekvensreserv FCR ; vattenkraft; dubbelreglerad DR turbin; icke-linjär modellering; Simulink.;

   Abstract : The frequency of the Nordic power system has been increasingly deviating outside the normal frequency band (50 ± 0.1 Hz) in the past two decades. In an effort to counteract this, the Nordic Transmission System Operators (TSOs) have proposed new and stricter requirements on the units participating in Frequency Containment Reserve (FCR) market.
