Popular Abstract in Swedish Vi går mot ett mer och mer energikrävande samhälle. För att klara ett ökande behov av energi med de begränsande naturresurser som finns på jorden, har ett forskningsprojekt, som denna avhandling är en del av, som mål att utveckla artificiell fotosyntes. Den naturliga fotosyntesen använder sig av solljus för att omvandla koldioxid och vatten till energirika produkter såsThe work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. The chlorophyll complex P680 absorbs light and electrons are tr

Ledord som opartiskhet, saklighet och objektivitet är vanligt förekommande i det rättsliga språket. Medan aktörer inom rättsväsendet gärna likställer denna orubbliga idé med en objektiv juridisk praktik, har forskare och andra aktörer hävdat att rättslig prövning långt ifrån alltid sker i en värderingsfri process – dvs. där juridiskt ovidkommande faktorer som kön, klass, etnicitet saknar betydelse

This paper presents the characterization of forced cooling channels with three different shapes which are applied in traction motors mounted in Hybrid Vehicles (HEVs) or Zero Emission Vehicles (ZEVs). Generally, there are two different positions of forced cooling channels in electric motors. One way is by drilling holes or cutting cooling channels inside the housing, which is called indirect cooli

We overview two approaches to the analysis of low-density parity-check (LDPC) codes: selected code approach and ensemble approach. As examples of application of the methods we consider Gallager's homogeneous LDPC codes and Berrou-Glavieux-Thitimajshima (BGT) turbo-codes

Popular Abstract in Swedish Långlivade klororganiska miljögifter (POP) som polyklorerade bifenyler (PCB), dioxiner och och insektsgiftet diklordifenyltrikloretan (DDT) har sedan decennier funnits i vår miljö. PCB framställdes genom klorering av bifenyl och det finns 209 olika varianter. En av dessa är CB-153, vilken är den vanligast förkommande PCB varianten, och vi har använt denna som biomarkör Persistent organochlorine pollutants (POPs), such as polychlorinated biphenyls (PCB) and the insecticide dichloro-diphenyl-dichloro-ethylene (DDT) have been released into the environment mainly since the second World War. POPs accumulate especially in highly ranked predators of the aquatic food chain. In Sweden, the major exposure route for POPs are through consumtion of fatty fish, such as salmon

A new method for characterization of simultaneous intra-atrial and ECG recordings during atrial fibrillation (AF) is presented. With different preprocessing, both types of signals are characterized using a logarithmic time-frequency distribution from which trends of frequency, regularity, morphology (only ECG) and signal quality are extracted. The objective of the study is to relate ECG measures o

Voltage collapse was one of the main causes for many recent blackouts. The direct link between voltage stability and reactive power balance in the system leads to more attention toward reactive power resources in the power systems. Shunt reactors and capacitors are used to balance reactive power in the power systems. The strategy to control them in both normal and emergency conditions is an import

Thread-Level Speculation can be used to take advantage of multicore architectures for web applications. We have implemented Thread-Level Speculation in the state-of-the-art JavaScript engine V8 instead of using an interpreted JavaScript engine. We evaluate the implementation with the Chromium web browser on 15 popular web applications for 2, 4, and 8 cores. The results show that it is beneficial t
