   Sammanfattning : The miniaturization of semiconductor technology and reduction in power requirements have begun to enable wireless self-sufficient devices, powered by ambient energy. To date the primary application lies in generating and transmitting sensory data. LÄS MER

4. 8. Study of a Large Deformable Mirror Concept

   Författare :Rikard Heimsten; Astronomi - Genomgår omorganisation; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Large deformable mirror - Adaptive optics - Distributed Control - Local control: actuator family - Faceplate: vibration modes - Faceplate: Dimensionless modal analysis;

   Sammanfattning : It is attractive to integrate a large deformable mirror for adaptive optics into an astronomical telescope rather than using relay optics within an auxiliary instrument. However, the resulting large deformable mirror can be expensive, particularly for extremely large telescopes. LÄS MER

5. 9. Semiconductor Quantum Optics at Telecom Wavelengths

   Författare :Katharina Zeuner; Val Zwiller; Klaus D. Jöns; Stephan Reitzenstein; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optik och fotonik; Optics and Photonics;

   Sammanfattning : Quantum technologies are an expanding field in physics and engineering concerning the development of protocols and devices that enable augmented or novel applications based on quantum mechanics. This includes amongst others quantum computation and quantum communication. LÄS MER

7. 10. Detecting the dynamics of single biomolecules

   Författare :Stefan Wennmalm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : This thesis is concerned with the detection of single biomolecules. Through detection of individual molecules it can be clarified whether a behavior which has been observed in a population is representative for all molecules. For detection confocal fluorescence microscopy was used, in particular Fluorescence Correlation Spectroscopy (FCS). LÄS MER
