With the continued development of tracking technology and increasing interest in animal movement, our understanding of migration behavior has become more comprehensive. However, there are still many species that have not been well studied, particularly sea birds. Here, we present the first year-round Global Positioning System (GPS) tracking data of the Black-tailed Gull (Larus crassirostris) at th
Pentachlorophenol (PCP) is a commonly found recalcitrant and toxic groundwater contaminant that resists degradation, bioaccumulates, and has a potential for long-range environmental transport. Taking proper actions to deal with the pollutant accounting for the life cycle consequences requires a better understanding of its behavior in the subsurface. We recognize the huge potential for enhancing de
In this paper we study the convex envelopes of a new class of functions. Using this approach, we are able to unify two important classes of regularizers from unbiased non-convex formulations and weighted nuclear norm penalties. This opens up for possibilities of combining the best of both worlds, and to leverage each method’s contribution to cases where simply enforcing one of the regularizers are
Reference attribute grammars (RAGs) have reached a level of maturity where they are supported by several tools, and have gained traction in both academic and industrial language tool development. However, despite a lot of accumulated knowledge of how to best develop RAGs in practice, there is limited support to guide practitioners.In this paper, we address this issue by focusing on one RAG tool, J
The Swedish electricity market was divided into four bidding areas on 2011.11.01. The division gave implications to the trade of electricity in the spot market as well as the financial market. Four bidding areas create smaller markets and coupled with an unbalance of production and consumption in the areas, the liquidity on contracts for area price risk management has decreased drastically. This e
Finding the optimal subset of individuals to observe in order to obtain the best estimate of the average opinion of a society is a crucial problem in a wide range of applications, including policy-making, strategic business decisions, and the analysis of sociological trends. We consider the opinion vector X to be updated according to a DeGroot opinion dynamical model with stubborn agents, subject

Utveckling av jordbrukssektorn är en av de viktigaste prioriteringarna för den Etiopiska staten när det kommer till att upprätthålla landets ekonomiska utveckling. Ett sätt att uppnå detta är att satsa på storskaliga utvecklingsprojekt inom jordbruket, till exempel Tana Beles Sugar Development Project som den här uppsatsen kretsar kring. För att kunna anlägga detta har stora landarealer tagits i aDevelopment of the agricultural sector is among the top priorities for the Ethiopian government in order to keep up the economic development in the country. One way of reaching this is to undertake large-scale development projects, such as the Tana Beles Sugar Development Project described in this thesis. For this, large areas of land are required for the plantations. This land is expropriated fro
The growing expansion of price comparison sites, where shops are compared and ranked in order of lowest prices, has contributed to reduced friction and transaction costs for consumers. Previous research in this field of study has primarily relied on examining the relationships between ranking and consumers’ demand for the resellers’ products. This thesis investigates and explains whether companies
The project justifies itself from increasing Europeanizing of the building market, new the possibilities of communication, mobility and occupation, which offer the European Union to humans and enterprise. Simultaneous substantial deficits are to be deplored in all countries involved in the vocational further training in the building sector. The project wants to make a contribution to: Improvement
Popular Abstract in Swedish Under de senaste årtiondena har vattenfärgen i många svenska sjöar och vattendrag ökat. Detta innebär att vattnet blir brunare, och detta fenomen benämns därför brunifiering. Brunifiering är inget unikt för Sverige, utan förekommer på åtskilliga ställen på norra halvklotet. Brunifieringen påverkar det akvatiska ekosystemet och vattnets potentiella samhällsnytta. Ur en eThe term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. From an ecological point of view the impaired light climate may e.g. reduce aquatic primary production and affect predator-prey interactions within the
Atmospheric new particle formation (NPF) is an important phenomenon in terms of global particle number concentrations. Here we investigated the frequency of NPF, formation rates of 10 nm particles, and growth rates in the size range of 10–25 nm using at least 1 year of aerosol number size-distribution observations at 36 different locations around the world. The majo
Popular Abstract in Swedish I och med de smarta mobiltelefonernas framväxt överförs allt mer data i de mobila nätverken. Detta ställer allt högre krav på mobilsystemen och de mobila enheterna. Ett effektivt utnyttjande av de tillgängliga resurserna är nödvändigt. Det tillgängliga frekvensspektrat är begränsat och måste utnyttjas så väl som möjligt. Detta görs bland annat genom att öka mängden dataIn this thesis different aspects of baseband implementation of mobile communication systems is treated. The content is focused on symbol detection and channel estimation in MIMO and OFDM. The thesis deals with the complete chain from algorithm to silicon implementation within these areas. The main contribution of this thesis is described in the included papers. The first paper handles symbol dete
The ordinary cities are the dominant sites of urban living, theorization and debates. This presentation centrally situates the dimension of urban density to unfold a unique, however, ordinary aspect of urban contention. It situates the state’s formal housing paradigm for the urban poor as the case of theoretical intervention from an ongoing research project. It aims to broaden the understanding of

We have estimated the activation energy for aromatic oxidation by compound I in cytochrome P450 for a diverse set of 17 substrates using state-of-the-art density functional theory (B3LYP) with large basis sets. The activation energies vary from 60 to 87 kJ/mol. We then test if these results can be reproduced by computationally less demanding methods. The best methods (a B3LYP calculation of the ac
The thesis presents fairness as a concept that can be defined in several ways. The different definitions overlap and influence each other in a somewhat unexpected manner. The conclusion of this thesis is that the utilitarian approach first presented as a philosophical theory of fairness by Jeremy Bentham is so far clearly seen as the overriding basis for the CJEU judgements. However, the adopted A
Scientists are increasingly exploring on-site water systems to supplement conventional centralized water and wastewater infrastructure. While major technological advancements have been achieved, we still lack a systematic view on the non-technical, or institutional, elements that constitute important barriers to the uptake of on-site urban water management systems. This paper presents a conceptual
The performance of three different backpack-mounted γ-radiation survey systems has been investigated. The systems are based on a LaBr3:Ce detector and a NaI(Tl) detector both with active volume dimensions of 76.2 mm in diameter and 76.2 mm length and a 123% relative efficiency HPGe detector. The detection limits of the systems were tested in a controlled outdoor environment in Sweden, followed by
