In this work we present a new low-power medium access scheme for sensor-type networks specifically with low traffic intensity. We call the proposed scheme DCW-MAC where ultra-low-power wake-up receivers are combined with optimal duty-cycled listening. First we introduce a framework for the analysis of energy consumption of the studied network type, then we use it to optimize the MAC scheme to achi
Varje medlemsstat har förbehållit sig rätten att lagstifta inom rättsområdet direkt beskattning. Det medför att medlemsstaterna är skatterättsligt suveräna och att gemensamma EU-beslut kan fattas inom detta rättsområde, under särskilda omständigheter. Trots detta har EU-domstolen sedan ca 30 år tillbaka, avkunnat domar som berör frågor huruvida regler inom den direkta beskattningens område är föreOver the years it has become clear that the Court of Justice of the European Union may, despite the principle of fiscal sovereignty rule on the compatibility of domestic tax measures belonging to the field of direct taxation, with the fundamental freedoms. Truthfully, the compatibility assessment is found much earlier in other fields of law. The last step of the methodology used by the Court encom
Iron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport. Recently, it has been shown that certain ectomycorrhizal (EC
The Øresund Basin in the transnational area between Sweden and Denmark forms a marginal part of the Danish Basin. The structural outline and stratigraphy of the Mesozoic succession is described, and a novel interpretation and description of the subsurface geology and geothermal potential in the North Sjælland Half-graben is presented. The subsurface bedrock in the basin includes several Mesozoic i
Denmark has long been known as a pioneer in renewable energy technology development. Apart from technological leadership, Denmark has also been the home to many community-based renewable energy initiatives. Citizen involvement in local energy projects has been key to increasing and maintaining acceptance to wind, solar and biomass. Three Danish islands (Bornholm, Samsø and Ærø) have been particula
District heating and cooling is a simple but powerful technology that could contribute to decarbonising Europe's heating and cooling supply. However, its current overall penetration is minor. Furthermore, future systems could adopt different configurations with various settings of temperature levels or production location. This thesis has aimed to improve existing tools to evaluate district heatin
Apart from being applied as an energy carrier, hydrogen is in increasing demand as a commodity. Currently, the majority of hydrogen (H2) is produced from fossil fuels, but from an environmental perspective, sustainable H2 production should be considered. One of the possible ways of hydrogen production is through fermentation, in particular, at elevated temperature, i.e. thermophilic biohydrogen pr
District heating and cooling systems have evolved through several development stages in order to improve their energy efficiency. The latest development reached the fifth generation where customers can be producers and/or consumers of thermal energy flows towards the network. The variety and complexity of system configurations and interactions between connected customers poses a challenge in adopt
α-Synuclein is a presynaptic protein associated to Parkinson's disease, which is unstructured when free in the cytoplasm and adopts α helical conformation when bound to vesicles. After decades of intense studies, α-Synuclein physiology is still difficult to clear up due to its interaction with multiple partners and its involvement in a pletora of neuronal functions. Here, we looked at the remarkab
Since its foundation, one of the main purposes of the European Union has been to create a single market where goods and services, as well as people, can move freely between Member States without internal borders nor other regulatory obstacles. Common intellectual property legislation is necessary as most goods and services indeed rely on intellectual property. This is particularly true for trade m
Family firms play an important role in the global economy. Family firms are defined as firms owned and managed by a family constellation. While their governance structure is different from non-family firms, family firms face similar questions of internalisation as their non-family counterparts. This study aims to determine how non-financial aspects may motivate the choice of internalising in f
In a recent paper Pedroni and Yao (2006) present strong evidence suggesting that Chinese provincial per-capita output is diverging, a result that goes against the Chinese government’s goal of a balanced wealth-creation across provinces. This paper provides an in-depth analysis of the reasoning behind this finding. Our main result is that the divergence does exist, even when new data and more advan
Uppsatsen är ett resultat av en explorativ studie av Business Intellience i några svenska företag. En grundläggande referensram presenteras för målgruppen för uppsatsen för attskapa en förståelse från grunden till studiens frågeställningar. Vad är Business Intelligence egentligen och vad betyder begreppet för dig? En analys av begreppet görs och ställs mot olika perspektiv i ett försök att definie
This paper investigates if there is hysteresis in unemployment rates for 8 OECD countries. Univariate unit root tests (ADF and KPSS tests) are performed as an initial analysis of the unemployment rates. These tests suggest that the hysteresis hypothesis is true. Since traditional unit root test have low power against fractionally integrated alternatives, the Sowell’s (1992) exact maximum likeliho
I dagens samhälle är innovation av tilltagande värde för såväl industrialiserade som utvecklingsländer och ett innovativt samhällsklimat innebär ett betydande bidrag till den ekonomiska tillväxten och till samhällsutvecklingen i stort. Det bokförda värdet hos dagens bolag består till en stor och växande del av immateriella tillgångar och det blir ständigt lättare att tillgå mer och bättre kunskap.In today’s society innovation is increasingly important for a developed, as well as a developing, country and it is a significant contributor to economic growth and the evolution of society. The accounted value of companies increasingly consists of immaterial property and our access to existing knowledge is ever greater and ever easier. Since ideas and innovations are of such great importance to m
This thesis investigates the impact that ESG-ratings have on valuation uncertainty. Because of the increased importance of sustainable investing, understanding the potential effect of a sustainability metric like ESG-ratings becomes increasingly important. This thesis uses an accounting-based valuation model to determine the valuation uncertainty. Using data from multiple ESG rating agencies a new
