DNA- cationic amphiphile and DNA-cationic polymer systems were studied with respect to the intermolecular interactions, as well as structure and stability of formed complexes. The thesis is divided in two parts: one section is a summary and the other section contains five papers. The summary is organized as follows; Chapter 2 gives an overview on the behavior of polyelectrolytes in solutions with
Unemployment and precarity have become key features of 21st century work. Employability is presented as a solution to these issues. Individuals are exhorted to manage their employability, in order to be able to exercise choice in the labour market. While employability is individualsʼ responsibility, governments, employers and educational bodies simply provide opportunities for its development. Hig
The transformation from analogue to digital recording techniques has not only changed the ways of working for the studiotechnician, but affects the musician in the way he thinks about performance and sound, and therefore also his actual performance. The signal processing and the staging of the singing voice in the studio is both influenced by, and influences the estethics of popular song performa
This thesis considers various aspects of implementation of high level parallel languages, specially Ada, on true multiprocessor architectures with shared memory.
Inom försäljning av avancerade tekniska produkter och tjänster finns en relativt klar konsensus om vissa principer. Framför allt råder det enighet om att förståelsen av kundnyttan kommer i första hand. Man måste se processen från kundens perspektiv, och det måste finnas en klar och lättförståelig nytta för kunden. När det gäller god undervisning råder inte samma uppenbara konsensus. Det är inte sj
Popular Abstract in Swedish Ehrlichia hos människor och djur Fästingburna infektioner uppmärksammas alltmer både hos människor och djur. Fästingar har visat sig kunna överföra flera olika infektiösa agens som till exempel borrelia- och ehrlichiabakterier, tick-borne encephalitis (TBE)-virus och babesia-parasiter. De i Skandinavien förekommande ehrlichia-bakterierna Ehrlichia phagocytophila, orsakEhrlichia phagocytophila is a tick-borne pathogen of domestic animals, which has recently been acknowledged also as a human pathogen. It is a strictly intracellular bacterium, infecting granulocytes of the host, sometimes resulting in clinical disease - granulocytic ehrlichiosis - with manifestations ranging from mild flu-like conditions to severe infections with multi-organ failure and death. Thi
This paper presents a new method for representing Light Propagation Volumes using an octree data structure, and for allowing light from regular point light sources to be injected into them. The resulting technique uses full octrees with the help of a separate data structure for representing the octree structure. The octree structure enables light propagation to be performed at a lower resolution t

In this paper, we give an overview of spatially coupled turbo codes (SC-TCs), the spatial coupling of parallel and serially concatenated convolutional codes, recently introduced by the authors. For presentation purposes, we focus on spatially coupled serially concatenated codes (SC-SCCs). We review the main principles of SC-TCs and discuss their exact density evolution (DE) analysis on the binary
This paper presents a new technique to coordinate distributed load switching in order to restore the voltage during disturbed conditions. The technique of today is mainly based on load shedding, but the restoration of the load is manually controlled. With increased and intelligent signal analysis in the distribution and transmission systems it is possible to switch load automatically, both on and
