1. A sub-5 fs 100 TW optical parametric synthesizer
Sammanfattning : State-of-the-art ultrashort light sources in the visible and near-infrared spectral regions provide direct access to the femtosecond realm, thereby enabling understanding and control of electronic processes within matter. On the other hand, ultra-intense light pulses lead to the emergence of relativistic electron motion and many related phenomena, such as electron & ion acceleration and high-order harmonic generation in plasmas.

2. Representation of Quantum Algorithms with Symbolic Language and Simulation on Classical Computer
Sammanfattning : Utvecklandet av kvantdatorn är ett ytterst lovande projekt som kombinerar teoretisk och experimental kvantfysik, matematik, teori om kvantinformation och datalogi. Under första steget i utvecklandet av kvantdatorn låg huvudintresset på att skapa några algoritmer med framtida tillämpningar, klargöra grundläggande frågor och utveckla en experimentell teknologi för en leksakskvantdator som verkar på några kvantbitar.

3. "Strunt alt hvad du orerar" : Carl Michael Bellman, ordensretoriken och Bacchi Orden
Sammanfattning : The 1760's and 1770's saw the emergence of numerous clubs, orders and societies in Stockholm. One of the most extraordinary expressions of this phenomenon was Carl Michael Bellman's Bacchi Orden, a series of semi-public dramatic entertainments chronicling the exploits of the members of Bacchi Orden, a fictional society enrolling several of Stockholm's most notorious drunkards and dedicated to the celebration of Bacchus.

4. Modelling and control of a line-commutated HVDC transmission system interacting with a VSC STATCOM
Sammanfattning : The interaction of an HVDC converter with the connected power system is of complex nature. An accurate model of the converter is required to study these interactions. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the HVDC system and the connected system components. LÄS MER
5. DIXI – a Hybrid Pixel Detector for X-ray Imaging
Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER
