This study focuses on the demand side of prostitution and sex-trafficking. The aim is to examine how young men construct the purchase of sex in the male peer group. We did six qualitative interviews with Swedish men between 20 and 30 years of age and used the theory of sexual scripts and stigma to analyse them. Through this, we could obtain that there is male peer groups where buying sex is constr
Sveriges vattenledningsnät kräver kontinuerliga och stora in- vesteringar och måste underhållas på ett effektivt sätt; syftet med den här studien var därför att utröna vilka ledningsattribut som är viktigast för att i en ANN-modell identifiera ledningar med hög risk för läckage. Detta gjordes genom att först använda attri- buturvalsmetoderna ReliefF och Recursive Feature Elimination (RFE) tillsammanSweden’s water pipe network demands continuous and large investments and must be maintained in an effective way; the aim with this study was therefore to investigate which pipe features are most important to identify pipes with a high risk of leakage in an ANN-model. This was done by first utilizing the feature selection methods ReliefF and Recursive Feature Elimination (RFE) with Random Forest Clas
Abstract The current Standard Model of particle physics contains few interactions resulting in a final state with two leptons with the same charge. Any observation of an excess of such same-sign dileptons would be an indication of new physics processes, making it a useful channel when searching for exotic physics. This thesis presents three projects conducted within the ATLAS Same-Sign Dilepton gr
Under the theory of weak-form market efficiency, present day stock prices reflect all historical data. As a result, the use of technical analysis should not be able to outperform a buy-and-hold strategy of a general market index. This study examines weak-form efficiency on the Swedish stock market by applying technical trading rules to 33 years of historical price data of the OMXS30 index. Variati
Popular science summary Habitat selection and chick survival of Eurasian Golden Plovers pluvialis apricaria altifrons during a lemming peak year in southern Lapland (Sweden) Aided by radio-telemetry, this study investigates the factors involved in the survival of Eurasian Golden Plover chicks and variations in habitat selection, home ranges and diet at different times through the pre-fledging pe
Populärvetenskaplig sammanfattning En förändring i det rådande klimatet med en temperaturhöjning på grund av en ökad atmosfärisk CO₂-koncentration kan komma att ha en påverkan på skogar över hela jordgloben. Trädarter som är anpassade till ett visst klimat kan komma att spridas norrut då klimatet kan vara mer passande i framtiden. Detta medför risken att lövträd från central Europa kan konkurrera A climate change will affect the forests around the globe; there may be competitions for available resources that are needed for growth and dispersal. Europe is supposed to be more sensitive and may experience a greater influence than many other regions. As an additional effect of climate change extreme weather events will be more frequent e.g. drought and extreme precipitation that will cause flo
In recent years a lot of criticism against the main assumptions of economic modeling has come to up, this has led to physicists entering the field of economics. By applying models originally developed for physics to economics, especially finance, analyzing methods with a different approach can be used. Inspired by earthquakes Didier Sornette created a model that analyze financial market crashes. W
This thesis provides a critical overview of the development of corporate governance practices in the EC. It seeks to determine if the Community should follow the US response to corporate governance fallouts or instead promote its own practices, taking into consideration the legal and economic backgrounds of the Member States. The analysis is supported with economic data, practical and doctrinal vi
The aim of this study was to examine if Landsat TM data could be used to : (I) estimate autumnal rape seed area (II) study the wintering of autumnal rape seed (III) estimate autumnal rape seed yield. The study took place in the province of Scania, Sweden. Two Landsat TM scenes, registrated 85-11-08 and 86-05-03, were included. The scenes were radiometric and geometric corrected in an image proces
The experimental power of a granddaughter design to detect quantitative trait loci (QTL) in dairy cattle is often limited by the availability of progeny-tested sires, by the ignoring of already identified QTL in the statistical analysis, and by the application of stringent experimentwise significance levels. This study describes an experiment that addressed these points. A large granddaughter desi
Robots used in manufacturing today are tailored to their tasks by system integration based on expert knowledge concerning both production and machine control. For upcoming new generations of even more flexible robot solutions, in applications such as dexterous assembly, the robot setup and programming gets even more challenging. Reuse of solutions in terms of parameters, controls, process tuning,
A search for long-lived particles decaying into hadrons is presented. The analysis uses 139 fb−1 of pp collision data collected at s = 13 TeV by the ATLAS detector at the LHC using events that contain multiple energetic jets and a displaced vertex. The search employs dedicated reconstruction techniques that significantly increase the sensitivity to long-lived particles decaying in the ATLAS inner
BACKGROUND: Ventilator resetting is frequently needed to adjust tidal volume, pressure and gas exchange. The system comprising lungs and ventilator is so complex that a trial and error strategy is often applied. Comprehensive characterization of lung physiology is feasible by monitoring. The hypothesis that the effect of ventilator resetting could be predicted by computer simulation based on a phy
Experimental results on the acceleration of protons and carbon ions from ultra-thin polymer foils at intensities of up to 6x10(19)Wcm(-2) are presented revealing quasi-monoenergetic spectral characteristics for different ion species at the same time. For carbon ions and protons, a linear correlation between the cutoff energy and the peak energy is observed when the laser intensity is increased. Pa
Particle image velocimetry is performed on a model of a high pressure homogenizer, scaled for qualitative similarity of the one phase turbulent flow field in a production scale homogenizer. Flow fields in gap entrance, gap and gap outlet chamber are obtained with high resolution. The measurements show gap flow development and formation of a turbulent wall adherent jet when exiting into the outlet
Abstract in UndeterminedIn this article we study the evolution of marriage seasonality in relation to economic change, particularly connected to changes in labour supply and work intensity of the kind implied by the ‘industrious revolution’. The focus is on southern Sweden in 1685–1894, which was a period of agricultural transformation and early industrialization, when we would expect to see an in
This rapport investigates the transmitter of the Ericsson Bluetooth radio. The open loop modulation scheme of the existing design is theoretically very simple but difficult to implement with available components. Frequency drift of the carrier is a common result of open loop modulation. This work therefore investigates an idea of frequency regulation where the regulation is active during modulatio
Uppsatsens syfte är att åskådliggöra den preventionistiska strömningen inom straffrätten och de uttryck den tar sig för att bekämpa terrorism. Framställningen står på två ben, förfältsgärningar och preventiva tvångsmedel, och de båda delarna redogörs inledningsvis var för sig. Först presenteras de osjälvständiga brottsformerna i allmänhet och sedan redogörs för de specifika gärningar som återfinnsThis thesis is mainly concerned with the inchoate offences and the preventive coercive measures in the Swedish criminal law, with a specific focus on the antiterrorism-legislation. My aim is to visualize the broad deterrentist trend, which in this thesis is called “preventionism”. To do so, the dependent forms of crime in general are presented in the first part, together with the specific inchoate
In the last couple of years it has become more and more common to use control theory in computing systems, for instance operating systems, web servers and databases. The reason for this is to make these systems more robust and stable. This is of interest because we today are more dependent on computing systems in our everyday life, and therefore put higher demands on them. A lot of focus has been
