21. Data acquisition and signal conditioning for low power measurement systems
Sammanfattning : Integrated circuit (IC) power consumption and die are two important parameters that can define its cost as well as performance. That is why these two topics remain very important both in industry and in the research community. LÄS MER
22. Control and Analysis of Pulse-Modulated Systems
Sammanfattning : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. LÄS MER
23. Control of Dynamically Assisted Phase-shifting Transformers
Sammanfattning : In this thesis, controllers for power oscillation damping, transient stability improvement and power flow control by means of a Controlled Series Compensator (CSC) and and a Dynamic Power Flow Controller (DPFC) are proposed. These devices belong to the group of power system components referred to as Flexible AC Transmission System (FACTS) devices. LÄS MER
24. Prediction, Design and Determination of Protein Structures
Sammanfattning : The three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. LÄS MER
25. Physical properties and structural stability of carbon nanotubes under extreme conditions
Sammanfattning : Carbon nanotubes (CNTs) have attracted an immense attention of the research community since reporting on this system by S. Ijima in 1991. A "single-walled" CNT (SWCNT) can be considered as a rolled-up single-layer graphene - a one atom-thick layer of carbon atoms arranged in a hexagonal lattice. LÄS MER
