A hypertest-algorithm, the BUMPHUNTER, is introduced briefly and tested by probing events containing muons in 8 TeV datasets from the ATLAS detector at the Large Hadron Collider (LHC) at CERN against a background spectrum created by selecting muons from different collisions. The hypertest looked for excesses of same sign di-muon pairs which could indicate the existence of a Majorana neutrino. The
Information är en värdefull tillgång, och att garantera dess säkerhet är en konstant utmaning för alla inblandade. Nuförtiden säljs det fler avancerade mobila enheter än datorer per år, men säkerheten i dessa enheter släpar efter jämfört med säkerheten som erbjuds för datoranvändare. Syftet med denna uppsats är att ta reda på hur medvetna användare är kring säkerhetsrisker som berör mobila enheter
The aim of our study was to examine how staff, working with unaccompanied refugee children experience their work and the children’s integration to the society. Many previous studies in the same field have often focused on the young refugees, how they perceive their situation and how they perceive the integration work. Our study is based on a qualitative research strategy and we used semi-structure
The purpose of this study is to examine how outreach workers create professional relationships with youngsters. The result was based on six professional outreach workers. The results were presented in the form of four individual interviews and one group interview. The theoretical framework of the study was the theory of communication and the theory of “the different levels of professional meetings
Trots det väldiga överflöd av forskning som finns om organisationsförändring är det idé att börja titta på förändring ur ett mer långsiktigt perspektiv. Detta mot bakgrund av den tidigare forskningen som konstaterar att omkring 70 procent av alla förändringsinitiativ som görs misslyckas. Därför är det väsentligt att förstå förändring och dess implementeringssvårigheter på en djupare dimension. Den
The aim of this study was to investigate whether students in the field of social work assess symptoms of depression and suicidal ideation differently, depending on the age of the client. A case vignette method was used where social work students in Lund (N=102) and Helsingborg (N=71) responded to one of two online questionnaires each. The case vignette featured a 78 year old client for the student
Endometriosis is a chronic gynecological illness affecting 10% of all women in childbearing age, 200 000 of them in Sweden, causing abdominal inflammation and adhesion formation, all of which inflicts pain. It affects every aspect of a woman’s life, not the least psychologically, leading to anxiety, depression and decreased function and decreased quality of life. This online survey explored what p
This work investigates how the heat produced by a solar dryer can improve the drying process of newly developed breathable membrane bags for drying and thus preserving fruits in developing countries and the increased efficiency of the process. For that purpose, a solar dryer was built and tested in an indoor solar simulator with similar irradiation as the sun. Due to a limited time span, only one
This essay will explore which social and cultural mechanisms that legitimatize a group of people to commit genocide by discussing the terms “victimization” and “de-humanization”. The essay starts with a research on the term “genocide”, specifically which groups that are, or are not, protected under the Genocide Convention and moves on to Stuart Kaufmans “symbolic politics theory” to discuss how po
Abstract: China’s development today no doubt has had the country placed in the centre of the stage. However, the past turns out to be the opposite if we look back. While the other major countries stepped into the industrial era it seems like China was still napping with its daydreams. In this paper we dig deeply into the political, economic and social aspects of the country at the time and we thin
The purpose of this study was to understand the relationship between poverty and crime, and what role poverty plays in relation to traditional crime from the perspective of ex-criminals. Eight semi-structured life story interviews were conducted in the southern county of Skane, with recently desisted and rehabilitated men. The age span was broad, ranging from 32 to 63 years of age. All interviewee
Från förbränning av industri- och hushållsavfall erhålls bland annat restprodukten slagg, vilket är bottenaskan från förbränningen. Varje år skapas stora volymer både i Sverige och i övriga Europa. Den naturliga processen karbonatisering, vilken involverar en reaktion mellan luftens koldioxid och kalcium i materialet, startar då slagg efter förbränning kommer i kontakt med luft. Karbonatiseringen From incineration of industrial- and household waste bottom ash is generated. A large volume of bottom ash is generated yearly in both Sweden and Europe. The natural carbonation process, which involves a reaction between carbon dioxide and calcium in the material, is initiated when the bottom ash reaches contact with air. The carbonation binds carbon dioxide to the bottom ash, decreases the pH and
This thesis examines the ejido system in Mexico in order to understand the dynamics of land tenure, governance and transaction costs through the lens of Elinor Ostrom’s theory of good governance. This case of the ejido system was chosen as their constitution that enabled a communal access land tenure regime in the agricultural sector, was amended to allow for privatization. The ejido serves as a p
This is an ethnographic study on how refugees and policies on asylum and immigration was debated on Facebook in Sweden during the so called ‘refugee crisis’. This study analysed the relation between the Facebook debate, and the way news media framed the ‘refugee crisis’ during three months in which Swedish asylum policy changed drastically: September 2015, November 2015 and January 2016. In Septem
Uppsatsens syfte är att undersöka maktrelationers påverkan vid kriser och samhällstörningar med särskilt fokus på hur detta framställs i utvärderingar av samhällets insatser vid kriser och samhällsstörningar. Det empiriska materialet består av två utvärderingar, dels utvärderingen efter skogsbranden i Västmanland 2014 (Sjökvist 2015) och dels utvärderingen efter helikopterrånet i Stockholm 2009 (R
Auralization is of interest in several disciplines - virtual reality, architecture and video games. Current trends in the eld of computuation have led to dramatic increases in performance in recent years. In this project, a prototype of an auralization-engine is developed. The program is capable of plausible room acoustic simulation in real time for a moving receiver and arbitrary room models. Thi
This report aims to compare methods that can be used to efficiently and accurately map digital price labels position in 3D space using a mobile robotic platform equipped with camera vision in a retail environment. The robotic platform built during the project uses four wide angle cameras to cover the full circular view in the horizontal plane. Installation of external systems for e.g. navigation c
This paper studies the possibility to exploit linear dependence in stock returns of the Swedish OMX 30 index. The main model studied in the paper is a Vector autoregressive (VAR) model. Ten years of data from the OMX 30 index is used, consisting of 27 stocks for the period 2006-2015 which is transformed into daily, weekly and monthly returns. First the significance of the models is tested and it i
