Scientific summary: Ground settlement due to groundwater drainage during construction is important to be considered since ground settlement may cause severe building damages. The calculation of ground settlement contained several parameters with different magnitude of uncertainties. Thus a risk evaluation of ground settlement is necessary. The aim of this thesis was first to build a soil strata mo

Open and tolerant societies have plenty of advantages over intolerant ones. This applies to everything from the population’s level of happiness to the society’s creativity and the economic growth. If employers discriminate against and hire people for other characteristics than strictly a person’s productivity, the company and the society will suffer from a productivity loss. Moreover, wage discrim

The aim of this essay is to find out how the people behind the alcohol abuser (relatives of alcoholics) are able to manage their living situation. We chose to interview six relatives to get answers to our questions. We also chose to interview a drug and alcohol therapist, to get a professional perspective. The questions we asked is were: “Can strategies based on the Coping Theory explain how the r

This research emerges from an ongoing debate about the plans of building a new Munch Museum in Oslo, Norway. In 2009 the proposal Lambda won the architectural competition issued by Oslo Municipality, and since then a conflict has accumulated regarding the architectural design, if the building fulfills the normative functions of an art museum, and what role the art museum plays as a knowledge-based

Den sociala omgivningens påverkan på vår mentala hälsa är viktig att försöka förstå. Mycket forskning har ägnats åt att undersöka hur omgivningen påverkar antalet personer som insjuknar med olika typer av psykiatriska diagnoser. Få har dock undersökt hur omgivningen påverkar symptombilden inom psykiatriska tillstånd som till exempel psykotiska sjukdomar. Psykos är ett tillstånd som kan innefatta t

The first part of the thesis aims to investigate the applicability of JGrafchart and its associated Model of Computation(MoC) for describing sequential control in aircraft primary power distribution systems. The motivation behind this is the need for better modeling tools and in particular support for separation between nominal control and fault handling. Also, as system complexity increases, bett

Environmental concepts are nowdays used so often that their meanings can be questioned. It seems as if everyone claims to act in a sustainable way. But what does sustainability really mean? If actors do not share the same understanding of environmental concepts it will be impossible to address the problem in question. Theories exist stating that it is through policy that society defines a problem

Hemodialysis is today the main treatment used for patients with renal impairment, a serious medical condition. Hemodialysis treatment handles a very delicate system which is why it is of the utmost importance that the dialysis machine has got a reliable safety monitoring system that can detect severe complications during treatment. A new such system is currently under development at Gambro, Lund,

Syftet med föreliggande studie var dels att beskriva den grupp som spelar massiva onlinespel (MMO), dels att undersöka vilka faktorer som har betydelse för ett eventuellt problematiskt datorspelande. Analysen baserades på 429 svar från deltagare som fyllt i en webbenkät bestående av flervalsfrågor fördelade på skalorna prestation, social interaktion, självreaktiv förväntan, flow, bristfällig självThe aim of this study was to provide a description of the Swedish massively multiplayer online (MMO) community, and to investigate factors pertinent to problematic gaming. The analysis was based on 429 answers from a multiple-choice web-based survey with questions spread across the following scales: achievement, social interaction, self-reactive outcome expectations, flow, deficient self-regulatio

In this thesis, the impact of unknown parameter estimation in the case of the volatility parameter in the Black-Scholes model on hedging is investigated. The objective is to develop a systematic and robust model of hedging to challenge the conventional delta and improved mean-variance hedge, and hopefully improve upon risk assessment values. The proposed algorithms were tested in situations of unc

Wind energy production is a section that became bigger and bigger thanks to the interests in finding new ways to produce energy that do not involve fossil fuels because of environment concerns, because of their costs and because of their limited amount. Even though wind energy was exploited also in the past, for example in wind mills, it is with wind turbines that all the problems affecting these

The day of bud burst (DBB) of different tree species are known to be affected by factors such as growing degree days and temperature. In this paper a two state Markov chain is used to model DBB for birch. The model is fit using logistic regression and LASSO regularization is used to evaluate which of many potential factors best forecast DBB. Data of birch from both Finland and the United Kingdom i

This master thesis describes how to compensate for the compliance of the Gantry-Tau robot. The main reason for this is to improve the performance of the robot. The compliance is modeled as nine springs, one for each cart and each link. The model seems promising but has only been tested in homing position of the robot but shows a positive result in decreasing the compliance. External control of the

I uppsatsen undersöks kunskapsuppfattningar i läromedelsannonser inriktade mot högstadiet, gymnasiet eller motsvarande. Det resoneras också kring hur forskning teoretiskt kan förhålla sig olika pedagogiska traditioner.

Taking a deeper look into Dorothea Tanning’s painting Insomnias by investigating the use of medium as a physical entity applied to the canvas, that create illusions. The materiality is brought into focus do it its diverse range in techniques as well as the use of the medium’s viscosity, creating effects only achieved thought experiments. The painting lends itself to the discussion on how the forma

Positiva psykologiövningar har påvisat goda effekter i strävan efter att optimera och främja människors välbefinnande. Speciellt stor potential har tacksamhetsövningar, då deras effekt till skillnad från många andra övningar inte tappar lika mycket allteftersom tiden fortlöper. Pilotstudien gick ut på att kartlägga effekterna av tacksamhetsövningar så som 3 blessings. Syftet med detta var att se o
