I takt med urbaniseringen och teknikens utveckling har ljudvolymen i våra städer ökat och idag utsätts omkring 2 miljoner svenskar för buller i sina hem. Trots att forskning har visat att långvarig exponering för buller är hälsofarligt har buller fortfarande inte någon större prioritet i planering av bostäder. Detta projekt syftar till att undersöka hur bostäder kan utformas för att dämpa obehagli
The continuously growing number of products containing nanoparticles makes their presence in the environment seem inevitable and given the well-known toxicity of dissolved metals, concerns regarding the toxicity of metal-based nanoparticles have been raised. Whether metal-based nanoparticles present similar or different toxicological effects compared to metal salts is a progressing field. In the p
Elförsörjningen som till huvuddel kommer från fossila bränslen uppfyller vanligen inte efterfrågan i Irak. Samtidigt som det finns goda förutsättningar och stor potential för att installera och utnyttja solel som en lösning för den bristande elförsörjningen men med omtanke som värnar om miljön. Idag har cirka 20 procent av den irakiska befolkningen ingen tillgång till el, de återstående 80 procentThe main supply of electricity from fossil fuels does not usually meet demand in Iraq. At the same time, there are good conditions and great potential for installing and utilizing environmental friendly electricity from solar energy as a solution to the lack of power supply. Today, about 20 percent of the Iraqi population has no access to electricity, the remaining 80 percent have no continuous el
An increase in large-scale agricultural investment in land has been going on since the global food crisis in 2008. Import-dependent countries have acquired large plots of land to secure food supplies. The investments had disastrous impacts on the local communities living on the land before the investment took place. Many have been expropriated and evicted from their lands, affecting their human ri
The world today stands at a cross roads when it comes to energy and electrical grids. A large part of the worlds population still lacks access to reliable working electricity 24 hours a day. Much of this is in remote and poor parts of the world. For much of the 20th century large centralized AC grids have been the norm to provide people with electricity. But for remote parts of the world including
Abstract: The importance of dietary fatty acids (FAs), in particular omega-3 and omega-6 polyunsaturated (PUFAs), for immune system functions has been recognised and well-studied in mammals over the last decades. Recent studies suggest that similar positive/negative (e.g. strengthened/weakened immune com-petence) effects can be present in avian species. In this study, I explored these effects of ω
Framväxten av separatistiska organisationer för rasifierade i Sverige har periodvis erhållit stor uppmärksamhet. Förespråkarna ser det som ett sätt för strukturellt underordnade att stärka varandra, medan belackarna ser det som begränsande och destruktivt. Förståelsen för hur diskursiva praktiker struktureras inom separatistiska rörelser är emellertid begränsad. I denna studie har en diskursanalys
There is limited research conducted into the field of male victims of intimate partner abuse. Although, recent Swedish studies show that male victimization from female offender may be equally prevalent as female victimization of partner abuse. Previous international examples suggest that male victims may be less likely to acknowledge themselves as “victims” and therefore less likely to take legal
In this thesis a system for tracking the fingers of a user using sound waves is developed. The proposed solution is to attach a small speaker to each finger and then have a number of microphones placed ad hoc around a computer monitor listening to the speakers. The system should then be able to track the positions of the fingers so that the coordinates can be mapped to the computer monitor and be
Unemployment, underemployment and stressful working conditions in today’s Greece comprise common phenomena whose consequences are not only evident in the socioeconomic sphere but also in the individual psychological sphere. The present investigation combines mixed methods focusing on the psychological impact of unemployment and underemployment on individual mental health, and on the role of attach
Indonesia has implemented national policies and legislations to encourage biofuel production as means to achieve energy security and self-sufficiency and to reduce reliance of fossil fuel reserves. However, there is still no clear road-map for the socio-technological transition. While acknowledging economic impediments, this case study investigates social and political obstacles to bioethanol prod
The memory is by far one of the brain’s most important and fundamental functions, but perhaps also one of the most unreliable. In order for information to be retained in memory, the brain performs, in a few milliseconds, an outstandingly complex process that is also very sensitive to external disturbances. With the information technology available today, it is easy to be distracted by redundant in
In this thesis, I investigate the socio-legal experiences of ethnic Russians in Estonia and also review their practical implications. In particular, I explore the following research question – What are the main challenges and possibilities for socio-legal integration of Russian minorities in Estonia? For this purpose, I conducted sev

An analysis of two-particle angular correlations was recently performed on measurements taken from pp collisions at $\sqrt{s}$ = 7 TeV by ALICE at the LHC. The correlations for mesons are in good agreement with simulations performed in Monte Carlo event generators such as PYTHIA and PHOJET, but there is a significant difference for baryons. We here investigate particle production mechanisms in PYT
This thesis considers the representation of intermittent and flexible power production in long-term energy system models, and more specifically at the Swedish hydropower's capability of balancing the variations from increased shares of power from intermittent energy sources. The thesis aims to investigate how a present national TIMES model can be improved to better capture the technical, physi
An adaptive control system is proposed for an unknown integrator process with unknown dead-time. The process dead-time and gain are estimated simultaneously using an extended regression model and recursive least-squares estimation. The parameter estimates are used to scale the actuator signal, transforming the unknown process into a known reference process, while the dead-time estimate provides de
Wide-angle distance measurements are needed for positioning with multilateration when there is no information about in which direction objects of interest are located. Several transmitters of varying kinds were evaluated in a data-driven way using a 6 DOF robot actuator. A wide-angle (±98 degrees) distance measurement system us- ing ultrasound was developed. The resulting solution was integrated i
