Syftet med denna studie är att ur ett sociologiskt perspektiv undersöka hur det är att bo i Barcelona och arbeta i ett internationellt callcenter som ung europeisk medborgare. Vad är det som motiverar individer att migrera och arbeta i Barcelona? Hur upplever de förutsättningar i arbetet, social gemenskap och hur uppfattar de sin tillhörighet? Dessa frågeställningar sätts sedan i en bredare kontexThe aim of this study is from a sociological perspective understand how it is to live in Barcelona while working in an international call centre as a young European citizen. What motivates these individuals to migrate to Barcelona? What is their perspective of work, social community and notion of belonging? These questions are later to be examined together with theories of migration, modernization

In this thesis the approximation properties of feedforward articial neural networks with one hidden layer and ReLU activation functions are examined. It is shown that functions of these kind are linear splines and the number of spline knots depend on the number of nodes in the network. In fact an upper bound can be derived for the number of knots. Furthermore, the positioning of the knots depend o

Wide band gap semiconductors such as gallium nitride (GaN) are attractive candidates for short wavelength optoelectronic devices and high-power/high-temperature electronics. Widespread commercial adoption has been hindered by great difficulties encountered in obtaining high-quality materials. No suitable substrate material is available, making lattice matching unattainable and resulting in high th

Visual search efficiency improves with repeated exposure to the same search problem, yet the mechanisms behind these search efficiency gains remain unclear. Investigating how eye-movement sequences evolve over repeated viewings is fundamental for understanding how skilful search develops over time and its role in learning and gaining expertise. Scanpath theory holds that repeated displays are inve

The purpose of this thesis is to study how femininity and masculinity are portraited in three Swedish national newspapers (Aftonbladet, Svenska Dagbladet and Dagens Nyheter), which all represent different points on the Swedish ideological spectrum. The focus of the studie was to answer how women and men are portraited with stereotypical traits, if there is similarities and differences and how the

Inom identitetsforskning finns det olika definitioner av identitet. För att få en djupare förståelse för begreppet identitet, har jag valt att undersöka hur kosovoalbaner förhåller sig till sin identitet i ett svenskt samhälle. De empiriska uppgifterna samlades in genom kvalitativa semi-strukturerade intervjuer. Min analys baserades på begreppen identitet, tillhörighet och kultur. Baserat på det e

Den digitala utvecklingens framfart, liksom globaliseringens många påföljder, banar inte bara väg för otroliga möjligheter utan sätter även en ständig press på moderna och internationellt etablerade företag. Inre såväl som yttre slitningar kan dock lätt uppstå när en ständigt accelererande utveckling forcerar fram förändringar. I samband med förändring väcks frågan om det råder en övertro till tek

With the wind farms moving further from shore, new challenges arise. Technicians must visit the turbines almost daily because of the constant need for maintenance. But when the transport time from shore to the wind farm turns into hours is some kind of permanent accommodation required at the farm for the technicians to live on. Apart fromaccommodation the deep water is a big challenge. This paper

Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. However, the implementation of these models require high-level proficiency in GIS and hydrology. Thus, man

This thesis will introduce and prove the theorem of the Hydra Game as well as the theorem surrounding the Goodstein sequence. The two problems which are clearly intertwined will be introduced and solved with the assumption that the reader has no previous knowledge of them and little to no knowledge of ordinal numbers. All results have previusly been reached and presented, most notably by Kirby and

Today's urbanization creates big cities. More and more people are facing the problem with the increasing housing prices, and they had often to live in small or shared apartments. Most of the kitchens in those apartments are often small, which leads to a increasing need to use the available space in a more efficient way. An investigation conducted for the existing solutions in the market, has r

This thesis is a study of the articles published in the Chinese newspaper 人民日报 Renmin Ribao, the People’s Daily, during the Great Chinese famine 1959-1961. The famine is considered to be the worst famine in the history of China and an estimated more than 30 million people died of starvation or illnesses brought about by starvation during these years. This thesis will be focusing on the articles pu

Obesity has reached epidemic proportions in high-income countries during the last decades. At a population level, the speed of the progression of this epidemic indicates that lifestyle changes are a major contributor to the rising obesity rates. However, a part of the population has remained lean despite being exposed to obesogenic lifestyles. The objectives of this master thesis project are i) to

En nanotråd är en struktur som har en diameter mellan 10 och 100nm, och en längd av några mikrometer. Nanotrådar kan vara gjorda av olika material, där halvledarmaterial av olika typer är väldigt vanligt. Halvledarnanotrådar används i forskning för att ta fram framtida solceller, LEDs och används även inom biologiska applikationer. Nanotrådar passar väldigt bra för att interagera med celler på gruSemiconductor nanowires have in recent years gained attention in life science and are used for many different biological applications. The effect nanowires have on cells are still not well understood, however, there is an increasing number of studies investigating these interactions. Gallium phosphide (GaP) substrates were patterned using electron beam lithography (EBL) to create a pattern of alte

This thesis presents the development of a numerical optimization algorithm for airfoils, and how it can be used in design of wind turbine blades. It was found that the developed algorithm successfully improves the goal parameters under given conditions and constraints. This research was conducted on behalf of Winfoor AB who has developed a conceptually new blade design, in which every single blade

Procedural generation as a concept is as old as computer graphics. It is usually defined as a method for creating data algorithmically as opposed to manually. Work in this area often revolves around noise functions and large degrees of randomness, which works well for chaotic structures and for generating natural environments, but it does not always suit more sophisticated and coherent environment

The aim with this thesis is to broaden the understanding of relations surrounding climate change in small-scale private forestry in Sweden by present results from an fieldwork study of a small sample of private forest owners in the south of Sweden. The thesis shows how forest owners are situated within socio-ecological, and political contexts that affect their possibilities to cope with, and shape

From a small stream draining an agricultural catchment area in south Sweden, a temporal analysis of the occurrence of legacy pesticides was carried out and correlated with contemporary groundwater levelling, precipitation and flow rate of the stream, in order to evaluate groundwater outflow as an entry route for pesticides in the stream. Based on continuous measurement data from two periods of 12

Kan man spåra framtida läkemedel i kroppen med radioaktivt fluor? Hur fungerar egentligen olika läkemedel? De allra flesta kanske inte bryr sig, så länge det lindrar din huvudvärk eller tar hand om din infektion. Men när man ska ta fram nya läkemedel måste man tyvärr vara lite mer noggrann än så. Eftersom kostnaden för att gå från en flaska på kemilabbet till en burk på apoteket ofta är miljardbelGalectin-3 is a soluble protein in the body that has been shown involvement in biological processes such as tumour growth and metastasis as well as auto immune disease. Molecules developed by Ulf Nilsson’s research group have shown inhibitory effect in in vitro and in vivo studies towards galecin-3 but to get detailed information about distribution in vivo studies using PET should be performed. Pr

Given the increasing performance disparity between processor speeds and memory latency, making efficient use of cache memory is more important than ever to achieve good performance in memory-bound workloads. Many modern first-level caches store instructions separately from data, making code layout and code size an important factor in the cache behavior of a program. This work investigates two met
