16. Ultra-low Power Design Approaches in Memories and Assist Techniques
Sammanfattning : The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. LÄS MER
17. Quantum memory development and new slow light applications in rare-earth-ion-doped crystals
Sammanfattning : When doped into solid state transparent crystals, rare-earth ions can have optically excited states with milliseconds coherence time and up to six hours coherence time for hyperfine levels after being cooled down to liquid helium temperature. This long coherence property makes them unique as solid state material and attractive for quantum information applications. LÄS MER
18. Coherent Processes in Rare-Earth-Ion-Doped Solids
Sammanfattning : This thesis describes a number of coherent processes, such as quantum information processing, superradiance and electromagnetically induced transparency, which have been experimentally implemented using rare-earth-ion-doped crystals. The rare-earths are a class of elements that have in common, an atomic structure that allows for very long lifetimes as well as coherence times, both on optical transitions and on spin transitions.

19. Efficient Processing and Storage for Massive MIMO Digital Baseband
Sammanfattning : Driven by the increasing demands on data rate from applications, the wireless communication standard has for decades been evolving approximately at a pace of one generation per ten years. Following this trend, the ambitious plan to replace the current cellular mobile network standard (4G) with the next generation standard (5G) is going through the standardization phase and is getting close to its actual deployment.

20. Arkitekterna och byggbranschen : om vikten av att upprätta ett kollektivt självförtroende
Sammanfattning : The dissertation deals with the relations between architects and other parties on the Swedish building market. The starting point is the pronounced desire for a stronger role that architects in general have, but also the rather conspicuous fact that architects are more or less invisible in the wider context of the building industry.
