This thesis deals with techniques for raising the programming level for a particular kind of computations, namely those on abstract syntax trees. Such computations are central in many program analysis tools, such as compilers, smart language-sensitive editors, and static analysis tools. All techniques presented in this thesis support modular description and efficiency and are capable of handling l
Graphic correlation using graptolites and conodonts provides a high-resolution timescale for correlating from coastal to deep oceanic sections and, thereby, also a detailed record of the sequence of changes during the Mulde Secundo-Secundo Event. That interval includes sedimentary facies otherwise unknown in older Wenlock to early Ludlow strata on Gotland. The identified sequence of changes includ
A light-induced photoluminescence (PL) enhancement in surface-deposited methylammonium lead iodide (CH3NH3PbI3) perovskites was investigated in detail using time-resolved luminescence microscopy. We found the PL intensity to increase up to three orders of magnitude upon light illumination with an excitation power density of 0.01-1 W cm(-2). The PL enhancement is accompanied by an increase of the P
Following changes on a European level, there are plans to also in Sweden reduce the characteristic value of shear strength of glued-laminated timber. In Sweden, a decrease of approximately 30% from a characteristic value of 4.0 MPa (for glulam L40) to 2.5 or 3.0 MPa is planned. This would mean that wood would lose competitiveness against other construction materials such as steel and concrete. T
During the period 2009-2011 Sweden had two really hard winters with lots of snow. The result was train delays because of snow in the railway switches. The purpose of this work is to highlight the problems that arise around switches during winter and to propose methods to reduce these problems. The switch has a core function of the railway system and must therefore work properly. Switches are also

In January 2014 a new system for archival description will take effect in all Swedish government agencies, as prescribed by the Swedish National archives. This system is based upon the notion of processes as a way to describe organizations; processes containing activities and transactions that renders traces of information. It is a system that is fundamentally different from the preceding one. The
Genom att tolka primärrätten har EU-domstolen fastställt att varje person som drabbats av skada till följd av företags överträdelser av EU:s antitrustregler (s.k. konkurrensskada) har en rätt att söka ersättning för sådan skada. Utformningen av hur rätten ska säkerställas har länge legat på EU:s medlemsländers bord. Under 2005 tog EU-lagstiftaren de första initiativen till att skapa ett harmoniserBy interpretation of the antitrust rules in the EU primary law the ECJ has determined that any person who has suffered loss due to a breach of the those rules have the right to seek damages. For a long time it was up to the member states to make sure that this right was sufficiently protected. In 2005 the EU legislator began a harmonization initiative for this right. In the preparatory acts it was
Enzymer är biologiskt aktiva molekyler med en katalytisk förmåga. Detta innebär enzym kan medföra en omvandling av ett ämne i en reaktion som normalt inte sker spontant. Laccas är ett enzym som kan bryta ner (oxidera) fenolföreningar, och i naturen förekommer det i växter, svampar och bakterier där det fyller olika funktioner.
Binära föreningar beståendes av sällsynta jordartsmetallerna och rutenium uppvisar intressanta egenskaper såsom superledande förmåga och intressanta magnetiska egenskaper. För att förstå varför vissa föreningar uppvisar sådana egenskaper är det essentiellt att studera föreningarnas kristallstruktur. I denna rapport undersöks föreningar, i 35-38 at. % Ru regionen, beståendes av praseodym, neodymiumBinary alloys comprising of the rare earth metals along with ruthenium, RE-Ru, have been noted to display superconductivity at low temperatures. Furthermore the alloys display interesting magnetic properties such as anomalies in magnetization measurements below the magnetic ordering temperature. In order to understand how some compounds obtain these intrinsic properties it is vital to investigate
I en värld där klimathot och resursbrist har växt fram till ett allt större problem på världsledarnas agenda har vikten av hållbar utveckling identifierats som en nyckelfråga i vägen mot en bättre framtid. En metod för detta är industriell symbios, som innebär att olika företag och organisationer gemensamt utnyttjar energi, nyttigheter, material eller service, för att på ett innovativt sätt skapa In a world where climate change and resource scarcity have grown to some of the main issues on the world leaders’ agenda the importance of sustainable development has been identified as a key challenge in the path towards a better future. One method for this is industrial symbiosis, where different entities collaborate over energy, utilities, materials or services to create value and lower cost an
VOR, the versatile optimal resolution chopper spectrometer, is designed to probe dynamic phenomena that are currently inaccessible for inelastic neutron scattering due to flux limitations. VOR is a short instrument by the standards of the European Spallation Source (ESS), 30.2m moderator to sample, and provides instantaneous access to a broad dynamic range, 1-120 meV within each ESS period. The sh
We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase where the system contracted down to separatio
Reducing emissions from forest degradation and deforestation, conserving and enhancing forest carbon stocks, and sustainably managing forests (REDD+) has emerged as one of the most anticipated climate change mitigation tools. This paper aims to understand and identify the underlying discourses that have dominated the emergence of REDD+, by identifying the key story lines in the policy and academic
Popular Abstract in Swedish Modelleringsarbetet utvecklat i denna avhandling, kan delas in i två huvudområden: självantändning i ottomotorer, samt förbränning och emissioner i dieselmotorer. En första version av ett motorsimuleringsprogram med detaljerad kemisk kinetik, utökad för att innefatta full-cykel beräkningar, användes för att visa den starka påverkan som kväveoxider i restgaser har på sjThe modeling work developed in this thesis can be divided in two main areas of investigations: autoignition related to spark ignition engine and combustion and emissions formation in relation to diesel engines. A first version of a detailed kinetics engine simulation program, extended to handle full cycle calculations, was employed in order to demonstrate the strong effect that nitric oxide from
The aim of this thesis is to examine the relationship between writing and alterity in three recent novels written by J. M. G. Le Clézio, Désert (1980), Onitsha (1991) and La quarantaine (1995), which deal with the encounter between the so-called primitive cultures and Western society. The first chapter contains a more general discussion on the discourse of alterity in literature and the French exo
We present extensive density-functional theory (DFT) based calculations of the clean Rh(111) surface and of CO/Rh(111) overlayer systems. We study both ground-state structural properties and core-level shifts from differences in total energies at different coverages and adsorption sites. Most results are obtained using using norm-conserving or ultrasoft pseudopotentials. The overall reliability of
Enterprise Systems (ES) are often the largest and most important Information Systems (IS) an organisation employs. Most ES are rented or bought as COTS (Commercial Off The Shelf) software. The use of COTS leads to a distinction between the development of the ES software—done by ES software providers, like SAP and Microsoft—and the implementation of ES software in a specific organisation. Implement
It is shown how first-order performance estimation of high-orderadaptive optics (AO) systems may be efficiently implemented in a hybridnumerical simulation by the use of 1) sparse matrix techniques forwavefront reconstruction, 2) undersampled pupil-plane turbulence-inducedaberrations, and 3) analytical models that compensate - in the limit ofinfinite exposure time - for the errors introduced by un
The European Prospective Investigation into Cancer and Nutrition (EPIC), which covers a large cohort of half a million men and women from 23 European centres in 10 Western European countries, was designed to study the relationship between diet and the risk of chronic diseases, particularly cancer. Information on usual individual dietary intake was assessed using different validated dietary assessm
