16. Thermal properties of volume Bragg gratings and its implications on lasers
Sammanfattning : This thesis contains the results of research on the spectral control of lasers, specifically, the thermal limitations of volume Bragg gratings (VBGs), employed as laser-cavity end mirrors. The investigations consisted of both experiments and numerical simulations. LÄS MER
17. Nonlinear Characterization of Wideband Microwave Devices and Dispersive Effects in GaN HEMTs
Sammanfattning : Measurements play a key role in the development of microwave hardware as they allow engineers to test and verify the RF performance on a system, circuit, and component level. Since modern cellular standards employ complex modulation formats with wider signal bandwidths to cope with the growing demand of higher datarates, nonlinear characterization using wideband stimuli is becoming increasingly important.

18. Thermal effects on parasitic eyeflukes in fish : a case study
Sammanfattning : .... LÄS MER
19. An ultrasonic density measurement technique : performance, thermal effects, experimental validations, and modeling
Sammanfattning : This licentiate thesis addresses the idea of measurement of the density of liquids using sound. The thesis can be dived into three sections: 1. An introduction that presents the need for the research and its future application into an ultrasonic mass flow meter. 2. LÄS MER
20. Characterisation of mechanical and thermal properties of tungsten for high power spallation target applications
Sammanfattning : The European Spallation Source (ESS), which is currently under construction in Lund, will use pure tungsten as the spallation neutron target. The tungsten will be irradiated by a 2 GeV proton beam, pulsed at a repetition rate of 14 Hz. LÄS MER
