Context. Effective temperature is one of the fundamental stellar parameters. A traditional spectroscopic way to determine it is from optical spectra using excitation balance of Fe-lines. With technological advances and the advent of the next generation telescopes there will be an emphasis on the relatively unexplored near-IR (NIR) wavelength region (1-5 μm). A method to determine the effective tem
This research seeks to find how the Spanish society perceives Personal Income Tax compliance. By following the Slippery Slope Framework developed by Kirchler (2008) the study aims at measuring perceived trust and power of Spanish authorities. Higher levels of trust in authorities and power of authorities are proportional to raised levels of tax compliance. Estimating respondent´s perceptions as to
In cognitive linguistics there are three prevalent theoretical perspectives on metaphor: (universal) conceptual metaphors, discourse metaphors and language-consciousness interactionism. This thesis looked for evidence of support for these positions by conducting an empirical study comparing motion-emotion metaphors in English, Spanish and Swedish, focusing on the source domain MOTION. Following th
The aim of this study is to understand how crowdsourcing campaigns in an online environment can change brand perceptions and behavioral intentions of non-participating customers. Therefore, the thesis connects two major concepts. First the phenomenon of crowdsourcing will be discussed with emphasis an emphasis on its use in marketing. Then crowdsourcing will be lined to the theoretical concept of
In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. Three receiver versions with different harmonic rejection techniques are compared in terms of noise fig
The human population is increasing and more wastewater, rich in nutrients, is produced. Increased levels of nutrients such as phosphorus, nitrogen and organic matter in water bodies present a risk for eutrophication, toxicity to the water-living fauna and oxygen depletion. Therefore, it is important to operate the wastewater treatment plants efficiently to limit the release of nutrients to the rec
Background and issue of study: The global financial crisis, climate change, demographic changes, and rising inequality are some of the global trends that put pressure on public leaders and organizations, civil society organizations and corporations to shift to a social and environmental sustainable development. Social innovations are demanded to be both drivers of positive societal change and forc
Concrete is sometimes damaged by freezing. The damage increases if salt also is present. The damage consists of the removal of small flakes on the surface of the concrete, the inner structure may however be completely unaffected. This surface damage may increase the degree of saturation and ingress of e.g. chloride ions, which may lead to inner frost damage and corrosion on the reinforcing steel.
