We construct a probabilistic model which “mimics” the behaviour of a certain number-theoretical algorithm. This model involves study of a binary tree with randomly labelled edges, such that the labels have different distributions, depending on their directions. A number of properties of this tree are rigorously studied. As an application, this study could suggest what one could expect in the origi
That data from polar orbiting satellites have detected a widespread increase in photosynthetic activity over the last 20 years in the grasslands of the Sahel is justifies investigating its role in the tropical carbon cycle. But this task is undermined because ground data that are generally used to support the use of primary production models elsewhere are lacking. In this paper, we profile a Light
The present communication reviews reasons to perform rescreening of chlamydia-infected persons. It brings up difficulties to differentiate between relapse and reinfection. Studies on follow-up of chlamydia-positive cases after therapy are reviewed. It also highlights reasons for therapeutic failure, like compliance, pharmacological factors, including poor bioavailability, wrong dose regimens, lack
This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. Therefore, new ways to build VCOs and quadrature VCOs (QVCOs) have been sought to overcome this smaller headroom, while still maintaining the high performance o
BACKGROUND: Indications for implantable cardioverter defibrillator (ICD) implantation have expanded considerably in recent years, resulting in steadily growing numbers of ICD recipients worldwide. The aim of this study was to review the overall experience with ICDs in Iceland. METHODS: This was a retrospective single centre study set at the University Hospital in Iceland. Data on all ICD implantat
The metallation of tetrapyrroles is believed to proceed via a sitting-atop (SAT) complex, in which some of the pyrrole nitrogen atoms are still protonated and the metal ion resides above the ring plane. No crystal structure of such a complex has been presented, but NMR and extended X-ray absorption fine structure (EXAFS) data has been reported for Cu2+ in acetonitrile. We have used density functio
This thesis explores the way how far-right populist movements manifest themselves through social media. It approaches the problem by taking a political psychology perspective of ontological security which informs the behavioural need of an individual and groups to search for stable identity narratives to create a secure feeling of biographical continuity. The theoretical assumptions further incorp
This study examines the dividend announcement effect on the common stock price by a signaling hypothesis approach on the Stockholm Stock Exchange. The event study shows a positive significant cumulative average abnormal return (CAAR) of 1,54 % for positive dividend announcement in the analyst model. For negative- and neutral announcement, the reaction is non-significant. Although, negative dividen
In the regulation of Trafikverket there is many technical requirements that the railway facility should face. The reason for its existence is to create a standardized facility with well balanced requirements that includes implementation and management. But still, sometimes there is a need for violating some requirements, for example when the motive of the requirements are not holding against the m
The punctuality of passenger transport within the Swedish railroad network has been featured heavily in Swedish media. A study done by the European Commission proclaim that the levels of dissatisfaction towards the railroad system is among the top within Europe. The punctuality is strongly connected to faults related to railroad switches, which stands for a quarter of total delays. The switches wi
Modern cars have a wide range of safety features to ensure that the driving is as safe as possible. One of these safety features is called electronic stability control, often abbreviated as E.S.C. The goal of the E.S.C. is to make sure that the car stays on the road even under dangerous circumstances such as a slippery road or the driver committing mistakes. During this project, a simulation progr
This thesis was an investigation to survey how the new automated testing tool LeanFT compared to the older tool UFT. The thesis was an exploration into the tool LeanFT, examining how well LeanFT performed with GUI testing, what features the tool offered and how usable it was for a tester of software. The purpose of this thesis work was to come to a resolution on whether the LeanFT tool was a more
Syftet med offentlig upphandling är att offentliga medel ska användas på ett så effektivt och konkurrensfrämjande sätt som möjligt. Det är viktigt att upphandling genomförs affärsmässigt samt att fri rörlighet för varor och tjänster inom EU främjas. Som medlemsstat i EU är Sverige skyldigt att harmonisera svensk lagstiftning med EU-rätt. Efter att ha läst Andrea Sundstrands artikel Jäv och self-clThe purpose of public procurement is to use public funds in as efficient and competitive terms as possible. It is important that procurement is conducted commercially and that free movement of goods and services in the EU is promoted. As a member of the EU, Sweden is obliged to harmonize Swedish legislation with EU law. After reading Andrea Sundstrands article Jäv och self-cleaning i offentlig upp
I studien vänder vi oss till en privat vårdaktör inom närsjukvården där syftet är att bidra med kunskap kring effektivitet och kvalitet samt den eventuella konflikten däremellan. För att möjliggöra undersökningen har vi utgått från följande två frågeställningar: Hur resonerar Capio Närsjukvård kring kvalitet och effektivitet? Samt hur förhåller sig Capio Närsjukvård till den konflikt som eventuell
During the last decade there has been many advances in the field of research focusing on term structure models that include macroeconomic risks. The fact that such risks adds to the predictive power of risk premia is evident. However, there is no such models that includes exchange rate dynamics and accounts for these potentially latent effects on the yield curve. This thesis presents a discussion
A lowered mineral density in the skeletal bones may indicate osteoporosis and an increased risk of fragility fractures. However, lower bone mass does not reveal the whole truth about the status of the bone quality. This thesis investigated the microstructure and mechanical properties of 14 trabecular bone plugs in order to get a comprehensive understanding of how the trabecular network changes fro
Since its first recorded instance, the state of emergency has become an integral aspect of the modern nation state’s legal apparatus and is a crucial mode of government crisis management. A state of emergency entails a temporary suspension of the rule of law and deviation from the protection of civil liberties. Emergency powers have been examined considerably within the fields of political science
Både värme och elbolag har krav på sig att mäta sina kunders förbrukning över tid, för att kunna göra en exakt debitering. Denna mätning resulterar i stora mängder data, och på sikt byggs en stor bank med kundspecifik information upp. Informationen kan bland annat användas för att ta fram användarspecifika kostnadsmodeller eller för att förbättra simuleringar över energianvändning i näten. E.ON ä
Syfte och frågeställningar: Syftet med arbetet är att utifrån ett konsumentperspektiv skildra hur detaljhandlare inom den svenska modebranschen kan använda hållbar marknadsföring för att uppmuntra kunder att välja hållbara plagg i sin konsumtion. Huvuduppgiften är att kritiskt granska den bevisat ineffektiva gröna märkningen av modeplagg som ska indikera ett bättre miljöval, för att sedan undersök
