2. Active Health Monitoring of Aerospace Composite Structures by Embedded Piezoceramic Transducers
Sammanfattning : The objectives of the thesis work were to study theinteraction between embedded piezoceramic transducers andcomposite structures as well as determine techniques tosimplify the Lamb waves analysis. Firstly, this studyconsidered the design of the embedded piezoceramic transducers. LÄS MER
3. Electrochemical and mechanical thin film sensors
Sammanfattning : This thesis focuses on the study of thin-film sensor technologies, novel microfabrication technologies, and thin-film technology in general. The work discusses electrochemical sensors and mechanical sensor technologies as well as fabrication strategies for them. LÄS MER
4. Rheology of cement grout : Ultrasound based in-line measurement technique and grouting design parameters
Sammanfattning : Grouting is performed in order to decrease the permeability and increase the stiffness of the material, especially soil and rock. For tunnelling and underground constructions, permeation grouting is done where cement based materials are pumped inside drilled boreholes under a constant pressure, higher than the ground water pressure.

5. Dynamic analysis of a novel electromagnetic transducer for hybrid vehicle and experimental verification
Sammanfattning : This thesis presents the results of the work carried out on the dynamic analysis and experimental performance measurements of a novel concept of electromagnetic system for hybrid vehicle powertrains. The main focus of this work is to present how this novel electromagnetic system can be operated in a hybrid vehicle and to show how a prototype of this system has succesfully been operated in a laboratory set-up.
