21. Exploring the Software Verification and Validation Process with Focus on Efficient Fault Detection
Sammanfattning : Quality is an aspect of high importance in software development projects. The software organizations have to ensure that the quality of their developed products is what the customers expect. Thus, the organizations have to verify that the product is functioning as expected and validate that the product is what the customers expect. LÄS MER
22. Rut Depth Prediction on Flexible Pavements - Calibration and Validation of Incremental-Recursive Models
Sammanfattning : In later years the development of pavement design has gone towards more and more analytically based methods. Future design will probably be based on incremental deterioration models. The objective is to evaluate different types of rut depth prediction models for an incremental design process. LÄS MER
23. Assessment and Some Improvements of Hybrid RANS-LES Methods
Sammanfattning : Motivated by numerical analysis of a shock/boundary-layer interacting (SBLI) flow in a duct, where some typical existing hybrid RANS-LES methods become awkward to give accurate predictions of the shock-induced corner separation bubble, a new hybrid RANS-LES method, has been proposed. The model is based on a low-Reynolds-number (LRN) $k-\omega$ RANS model, which is one of the few models that are capable of giving reasonable predictions for the SBLI flow in RANS computations.

24. System identification of large-scale linear and nonlinear structural dynamicmodels
Sammanfattning : System identification is a powerful technique to build a model from measurement data by using methods from different fields such as stochastic inference, optimization and linear algebra. It consists of three steps: collecting data, constructing a mathematical model and estimating its parameters. LÄS MER
25. Infrastructural requirements for indirect and direct electrification of road transportation
Sammanfattning : This thesis analyzes the integration of electricity and transportation systems for a future in which transportation is increasingly electrified. The focus is on exploring the infrastructures required for the indirect electrification of heavy transportation and the direct electrification of passenger vehicles. LÄS MER
