Popular Abstract in Swedish Kvinnomisshandel är ett ärende som skiljer sig från andra polisärenden genom att det beskrivs som svårt att hantera. Polismän säger sig vilja agera men på grund av olika svårigheter - organisation, lagstiftning, de inblandades inställning - är man förhindrad att ingripa. I Vilja med förhinder låter Magnus Lundberg polismännen komma till tals. Genom åskådliggörande exemp
In connection with the international housing exhibition Bo01 in Malmo, Sweden in 2001, several residential units were built. To get building permission, all developers had to present calculations proving that their buildings would use in total less than 105 kWh/(m(2.)year) bought energy. Measurements show that none of the buildings fulfilled the demand concerning energy use. According to the calcu
The Soviet era had come to an end and by 2002 a new idea of Europe was emerging which would see the enlargement of the European Union. The period called ‘transition’ was relegated to history. It denoted the transition of the Baltic and Central European states from the Warsaw Pact and the Soviet bloc to NATO and the European Union. Originally, transition was a concept used only to denote that the f
For biomass fuelled CHP in sizes below 100 kW, Stirling engines are the only feasible alternative today. Using wood powder as fuel, the Stirling engine can be heated directly by the flame like when using a gaseous or liquid fuel burner. However, the combustion chamber will have to be much larger due to the slow burning of the fuel. To avoid sintering of ash the flame temperature in a biomass burne
The challenges for creating a greener economy and the institutional framework for sustainable development pass necessarily, or mostly, through cities, as they concentrate a large and growing part of the world’s economy and population, as well as decision-making power. With the processes of urbanization and rural-urban transformation, the economy in cities, especially in cities of developing countr
Spatially-Coupled LDPC (SC-LDPC) codes have been recently shown to be very efficient for transmissions over nonergodic channels, in particular over block-fading channels [1]. In fact, it is possible to design a SC-LDPC code with any given code diversity [2]. In this work, we investigate the performance of SC-LDPC codes over block-fading channels, assuming a mismatch (or offset) between the first b
Shadowing from other vehicles can degrade the performance of vehicle-to-vehicle communication systems significantly. It is thus important to characterize and model the influence of common shadowing objects like trucks in a proper way. However, the scenario of a truck as an obstacle in highly dynamic rural and highway environments is not yet well understood. In this paper we analyze the distance de
A search for first generation excited neutrinos is performed using the full e(-) p data sample collected by the HI experiment at HERA at a centre-of-mass energy of 319 GeV, corresponding to a total luminosity of 184 pb(-1). The electroweak decays of excited neutrinos nu* -> nu gamma, v* -> nu Z and nu* -> eW with subsequent hadronic or leptonic decays of the W and Z bosons are considered. No evide
Seed particles of elements or compounds which may or may not form alloys are now used extensively in promoting well-controlled nanowire growth. The technology has evolved following the well-known Vapour-Liquid-Solid (VLS) model which was developed over 40 years ago. This model indicates that a liquid alloy is formed from the seed particle and the growth precursor(s), resulting in crystal growth by
The mystacocarid crustacean Derocheilocaris typica has two microvillar organs, one new, the other previously unappreciated in crustacean literature. The first is situated on the head-shield and consists of three pairs of cells: one with microvilli and a ballooned nucleus; one smaller and without special features; the third large and investing the other two and extending down to the foregut. We cal
Popular Abstract in Swedish De ökande kraven på högre datahastigheter inom trådlös kommunikation ställer allt högre krav på både radiosändare och mottagare, då dessa behöver utnyttja fler frekvensband med större bandbredd vid högre frekvenser. Fokus i denna avhandling ligger på högfrekvensdelen av radiomottagaren, som består av lågbrusförstärkare, blandare, och oscillatorer vid mikrovågsfrekvenserThe increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. Tra
