1. 1. Analysing Regime-Switching and Cointegration with Hamiltonian Monte Carlo

   Master-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Jakob Brandt; [2023]
   Nyckelord :Time Series Econometrics; Regime-Switching; Cointegration; Markov Chain Monte Carlo; Hamiltonian Monte Carlo;

   Sammanfattning : The statistical analysis of cointegration is crucial for inferring shared stochastic trends between variables and is an important area of Econometrics for analyzing long-term equilibriums in the economy. Bayesian inference of cointegration involves the identification of cointegrating vectors that are determined up to arbitrary linear combinations, for which the Gibbs sampler is often used to simulate draws from the posterior distribution.

3. 2. Deep Generative Modeling : An Overview of Recent Advances in Likelihood-based Models and an Application to 3D Point Cloud Generation

   Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

   Författare :Shams Methnani; [2023]
   Nyckelord :;

   Sammanfattning : Deep generative modeling refers to the process of constructing a model, parameterized by a deep neural network, that learns the underlying patterns and structures of the data generating process which produced the samples in a given dataset, in order to generate novel samples that resemble those in the original dataset. Deep generative models for 3D shape generation hold significant importance to various fields including robotics, medical imaging, manufacturing, computer animation and more. LÄS MER

4. 3. Modeling of a Hydraulic Rock Drill for Condition Monitoring

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Adam Kagebeck; Mahdi Najafi; [2022]
   Nyckelord :Condition Monitoring System; Hydraulic Rock Drill; Diagnostic; Modeling; State Space Model;

   Sammanfattning : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. LÄS MER

5. 4. Towards Automatic and Systematic Compressor Model Selection Based on Measurement Data

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Henrik Holmberg; [2021]
   Nyckelord :;

   Sammanfattning : Centrifugal compressors are mechanical devices that move and compress gas and are used in a wide range of applications. To get as much efficiency out of the compressors as possible, high demandsare put on having good compressor models. LÄS MER

7. 5. FE modeling of glulam beams with mechanical slotted-in steel plate connections.

   Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Musaab Mahjoub; [2021]
   Nyckelord :Timber joints; Slotted-in steel plate connections; Python scripting; FEM; Abaqus.;

   Sammanfattning : The mechanical behavior of timber beams with a slotted-in steel plate connection is studied by creating a numerical model that is able to simulate the global bending behavior, the global load carrying capacity and the nonlinear plastic fastener force distribution in the connection. Experimental results from Material Testing Institute (MPA), University of Stuttgart were used to verify the simulation results from this study. LÄS MER
