21. Silicon nitride-based integrated components for optical communication
Sammanfattning : To follow the trend of the data traffic and to limit the size of the hyperscale data centers, communication solutions offering small footprint, low cost and low power consumption are needed. Optical interconnects used in data centers are mostly short reach (approximately 100 m) based on GaAs-based 850 nm vertical-cavity surface emitting lasers (VCSELs) and OM4 multimode fibers (MMF).

22. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates
Sammanfattning : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. LÄS MER
23. Testicular cancer – response adapted treatment, prognostic markers and survivorship issues
Sammanfattning : In the US and most European countries, testicular cancer is the most common malignancy in young men aged 20-40 years. Since the introduction of cisplatin-based treatment in the 1970s, more than 95% of the patients are cured. LÄS MER
24. Water erosion modeling using fractal rainfall disaggregation- a study in semiarid Tunisia
Sammanfattning : In the Tunisian semiarid area, water erosion processes have led to negative economic and environmental consequences in a context of limited water resources. To characterize and predict these degradation phenomena, a comprehensive high-resolution data base on erosive rainfall, together with siltation records for 28 small reservoirs were analyzed. LÄS MER
25. Economic aspects on obesity. Results from the Swedish obese subjects study
Sammanfattning : Aims: To analyse the patterns of sick leave, disability pension and drug consumption, and the willingness to pay (WTP) for obesity treatment among obese individuals. To estimate indirect obesity-related morbidity costs and direct costs of medication in relation to these costs in the general population. LÄS MER
