1. Structures of String Matching and Data Compression
Sammanfattning : This doctoral dissertation presents a range of results concerning efficient algorithms and data structures for string processing, including several schemes contributing to sequential data compression. It comprises both theoretic results and practical implementations. LÄS MER
2. Folkets fonder? : En textvetenskaplig studie av det svenska pensionssparandets domesticering
Sammanfattning : The social and political background for this study is the change in Sweden from a system of a collective pension scheme to a system that includes elements of individual responsibility and a higher personal involvement of Swedes in pension saving funds. This phenomenon has been conceptualized as domestication, a metaphor that serves as a unifying notion in this study. LÄS MER
3. Method and technique development in peptide and protein mass Spectrometry
Sammanfattning : Mechanistic studies and applicability of several methods and techniques for studying peptides and proteins with mass spectrometry are presented. A model for the protein molecular ion formation in explosive matrix-assisted plasma desorption mass spectrometry is proposed, involving a contribution from the chemical energy release during conversion of the explosive, an enhanced protonation through collisions with products from the explosive decay, and electron scavenging by other products.

4. Fabry-Pérot based refractometry : development of a transportable refractometer for assessment of gas pressure
Sammanfattning : A unified description of physical phenomena through measurement science is one of the foundational pillars in a global society. The International System of Units (SI) is the most widely used system of units and since its redefinition in 2019, all units encompassed by it are based on fundamental physical constants. LÄS MER
5. Low-Temperature Heating and Ventilation for Sustainability in Energy Efficient Buildings
Sammanfattning : In 2013, the building sector consumed approximately 39 % of the total final energy use in Sweden. Energy used for heating and hot water was responsible for approximately 60 % of the total energy consumption in the building sector. Therefore, energy-efficient and renewable-based heating and ventilation systems have high potential for energy savings. LÄS MER
