1. Controlled Trapping in Laser Wakefield Accelerators
Sammanfattning : Experimental studies of laser-driven acceleration of charged particles, in particular electrons and protons, are described in this dissertation. Tightly focused femtosecond laser pulses with intensities exceeding 1018 W/cm2 were used to accelerate charged particles to high energies over distances of a few millimeters. LÄS MER
2. Huvudgårdar och herravälden : En studie av småländsk medeltid
Sammanfattning : This dissertation focuses on the medieval nobility and its manors in the inland of Småland. The problems tackled in the dissertation may be divided into two major complexes. LÄS MER
3. Probabilistic System Effects in Timber Structures
Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER
4. Low-Power Clocking and Circuit Techniques for Leakage and Process Variation Compensation
Sammanfattning : Over the last four decades the integrated circuit industry has evolved in a tremendous pace. This success has been driven by the scaling of device sizes leading to higher and higher integration capability, which have enabled more functionality and higher performance. LÄS MER
5. Low-Power Multi-GHz Circuit Techniques for On-chip Clocking
Sammanfattning : The impressive evolution of modern high-performance microprocessors have resulted in chips with over one billion transistors as well as multi-GHz clock frequencies. As the silicon integrated circuit industry moves further into the nanometer regime, three of the main challenges to overcome in order for continuing CMOS technology scaling are; growing standby power dissipation, increasing variations in process parameters, and increasing power dissipation due to growing clock load and circuit complexity.
