In this thesis structural optimization of castings and thermomechanical analysis of castings are studied by using surrogate models. In this paper an optimization algorithm is created by using Matlab. The algorithm is linked to the commercial FE solver Abaqus by using Python
Structural dynamics engineers are asked to make measurements for distinguishing differences between two structures. A frequent approach is to compare the modal parameters by change in Modal Assurance Criterion behaviour which focuses only on the Eigen values and Eigen vectors. A Graphical
In the early 1930´s, researchers were inspired by sonar to use ultrasonics for noninvasive examination. Even after 75 years, ultrasonics still is a big research area and new applications are coming up in a steady pace. The use of ultrasonic imaging has
A system converting textual information into speech is usually denoted as a TTS (Text-To-Speech) system. The design of this system varies depending on its purpose and platform requirements. In this thesis a TTS synthesizer designed for an embedded system operating on an
Tinnitus is a medical condition that manifests itself as a ringing, beeping, or humming noise to the affected person. The intention of this project is to help people with tinnitus recreate the sound they hear inside their heads. This is done to
In railway vehicles, air springs are used for isolating vibrations and improving comfort for the passengers. For the prediction of the vibrations in the car body, a valid model of the air spring is needed. A new model for simulation of the
