1. Weld Pool Simulations
Sammanfattning : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.

2. On the Optimization of Schedules of a Multitask Production Cell
Sammanfattning : Volvo Aero has invested in a complex production cell containing a set of multipurpose machines. The problem of finding optimal schedules for this multitask cell is a complex combinatorial optimization problem which is recognized as a flexible job shop problem. This thesis proposes an approach to find such schedules using mathematical optimization. LÄS MER
3. Parallel algorithms and implementations for genetic analysis of quantitative traits
Sammanfattning : Many important traits in plants, animals and humans are quantitative, and most such traits are generally believed to be regulated by multiple genetic loci. Standard computational tools for analysis of quantitative traits use linear regression models for relating the observed phenotypes to the genetic composition of individuals in a population. LÄS MER
4. Parallelizing the Method of Conjugate Gradients for Shared Memory Architectures
Sammanfattning : Solving Partial Differential Equations (PDEs) is an important problem in many fields of science and engineering. For most real-world problems modeled by PDEs, we can only approximate the solution using numerical methods. Many of these numerical methods result in very large systems of linear equations. LÄS MER
5. The role of students' identity development in higher education in computing
Sammanfattning : Higher Education Research in science, technology, engineering, and mathematics (STEM) indicates that students are not well supported in the process of integrating their educational experience with their perception of who they are and want to become. This is associated with drop-out and also has consequences for student learning. LÄS MER
