Partikelfysik är den del av fysiken som beskriver de allra minsta beståndsdelarna i vår värld. De ekvationer som används för att beskriva dessa små partiklar kan vara mycket svåra att lösa, det finns faktiskt ett pris på en miljon dollar till den som lyckas lösa ett visst problem inom partikelfysik. För att underlätta alla beräkningar som ska utföras, så har fysiker tagit fram några regler som manSolitons are solutions to classical field equations that are particle like, meaning they are localized in space, have definite energy and can be stable against deformations into the vacuum. In this thesis we investigate under which circumstances such solutions may exist and what effects their existence could have. It will turn out that topological considerations will play a large role in the quest

Small biological airborne particles (aerosols) reside in the atmosphere and can influence human health, the climate and the environment. Whereas aerosol sampling technology is well-known, there is currently no satisfactory high-volume flow impinger for health and atmospheric monitoring applications. The aim of this thesis was to design and construct a working prototype of an impinger, a sampling d

Today, it seems as if every second designed object is referred to as timeless design. We use the word timeless as a selling word without really thinking about what it means. Through investigating the concept of timeless design, I found the physical paper book being probably one of our most timeless objects. There are tons of book storing furnitures on the market of which the majority consists of

Foreign direct investments (FDI) have in later years become regarded as a key engine to economic growth, which many developing countries find appealing. Developing countries do however often find it hard to attract FDI since they have an unstable political environment due to inferior levels of democracy. To overcome this issue, they turn to bilateral investment treaties (BITs) with the hope that t

The aim of this Master’s thesis is to research the presence of lesbians in historical archives. My material consists of interviews with four swedish archivists. The aim of these interviews is to research the priorities and the work that is beeing done at the archives concerning collecting material that is missing in the archive and making existing material related to lesbian lives accessible. Fu

The aim of this Master's thesis is to investigate the choices that legal deposit libraries in Sweden make, during the process of collecting and displaying printed ephemera. The word “ephemera” originally derives from a Greek word simply meaning “short-lived” or “lasting only for one day”. The term “printed ephemera” thus refers to a wide range of different documents meant to be discarded after

Barriärer och möjligheter för klimatkrav vid upphandling av infrastruktur Att ta hänsyn till klimatpåverkan vid byggnation har på senare år blivit en del av den offentliga upphandlingen. För att nå Sveriges uppsatta mål om att vara utan nettoutsläpp av växthusgaser 2050, måste en förändring ske i alla led i samhället. Formulering av klimatkrav vid upphandlingen borde väl därför kunna användas somClimate change is one of the biggest challenges facing today's society. The construction sector contributes with a substantial part of the country's carbon dioxide emissions and accounts for a large part of Sweden's public procurement. Setting environmental requirements is therefore a very important part of the procurement process to ensure that the production of buildings and infrastr

The purpose of this study is to investigate the influence of non-conventional violence on the implementation of disaster risk reduction projects in the Northern Triangle of Central America. The Northern Triangle is facing substantial disaster risk from various hazards. Hence, there is a need for disaster risk reduction in the region. However, besides the challenges in terms of disasters, this regi

I det blomstrande forskningsfältet om planeter och exoplaneter, det vill säga planeter utanför vårat eget Solsystem hittar vi konstant nya planeter och system som alla ger oss pusselbitar till att förstå hur planeter formas och utvecklas. Så för att förstå de observationer vi gör och bedöma hur sannolikt det är att det kan finnas liv på en planet, måste vi förstå alla olika typer av system och hurIn the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. Some of this remaining material forms into a protoplanetary disk around the protostars

A fleet of autonomous sailboat could change our perception of the planet. An autonomous sailboat could not only conduct environmental research but also perform month long operations through the energy efficient wind propulsion. This thesis is the work behind the development of an autonomous catamaran model sailboat. A new mathematical model is brought forward and implemented for simulations perfo

Detta arbete är en översiktlig utvärdering av de konsekvenser som en förtätning i villaområden i Malmö kan tänkas bära med sig. Ett villaområde utgör typiskt en exklusiv boendemiljö i staden, med ett begränsat utbud av boendeformer och en trög omflyttning på bostadsmarknaden. Försöken i arbetet belyser att villaområden generellt har kapacitet att hysa fler hushåll, bli mer inkluderande och fungeraThis report is an evaluation on a general scale, concerning the consequences of densifying single housing areas in Malmö. An area consisting of single homes typically makes out a priviliged living environment, with a uniform range of homes, regarding residential sizes and forms for tenure, and a slow turnover in the housing market. This report attempts to show that single housing areas in general

Föroreningssituationen i Skurups dagvattensystem Regn- och avrinnande vatten, så kallat dagvatten riskerar att förorena vattendrag, mark och grundvatten med dagens separerade avrinningssystem som oftast leder direkt till recipient utan behandling. Tungmetaller är några av dessa föroreningar som undersöktes i Skurups stads dagvattensystem. På alla undersökta platser kunde tungmetaller återfinnas meThis study investigate the pollution levels (heavy metals) in Skurups city’s storm watersystem. Rain and runoff water (storm water) can be polluted and pose an environmental problem because it rarely gets purified on the way to our waterways. To find the various outlets where storm water reaches waterways, Skurups urban storm water systems were mapped. The city’s different businesses inside indust

Using a six-legged-robot as a development platform this thesis aimed to have a fully autonomic robot capable of navigating and mapping previously unknown terrain in three dimensions. During the project both hardware and software upgrades have been made such as implementing another computer on the robot and enabling wireless communication via Wi-Fi. Experiments were performed on a test track that

Syftet med uppsatsen har varit att bättre förstå hur unga konsumenter hanterar konsumtions- och servicemisslyckanden genom att söka en fördjupad förståelse av hur val av deras hanteringsstrategier (coping strategies) kan tolkas. Frågeställning: Hur ser unga konsumenter på konsumtions- och servicemisslyckanden och hur beskriver dem de hanteringsstrategier de använder? Metod: Kvalitativt angreppssät

A driver model can be used to predict the vehicle velocity and the energy consumption. It can be modeled such that it benefits from historical data and can be further improved if a navigation system is available. A well implemented driver model is important since the car fleet seems to be more and more electrified. The role of the driver model would then be to increase the accuracy for when the dr

Integrated modular avionics (IMA) architecture is an emerging concept in the military aerospace industry after being successfully implemented in the commercial domain. The highly modular architecture allows multiple aviation applications to execute on the same hardware thanks to defined standards by Aeronautical Radio, Incorporated (ARINC). System architects are responsible for designing and takin

60 % OF YOUNG SWEDISH PEOPLE IN THE AGES 18-25 ARE WORRIED ABOUT NOT SUCCEEDING IN LIFE. 72 % FEEL THERE IS AN IDEAL. 89 % OF THE WOMEN ARE STRESSED ABOUT LIVING UP TO THE IDEAL, 66 % OF THE MEN. THIS PROJECT IS AN INVESTIGATION OF PERFORMANCE ANXIETY. We live in a society where performances are valued so high that we believe it defines who we are. And for some reason it is okay to talk about inj

Enligt den amerikanska forskaren Richard Florida är det idag kreativitet och initiativkraft som driver ekonomin och utvecklingen framåt. Det samhälle som lyckas bäst är det som bäst tar vara på befolkningens kreativa potential och som mest framgångsrikt lockar till sig kreativa individer. Genom att analysera vilket samband som finns mellan Skånes kommuners satsningar på kultur & fritid och fasThe study aims to see if there is an impact of culture & leisure on property prices. To determine if there is a correlation method of regression analysis is used. The analysis is applied on two models, which will be called: Kommunmodellen and Staffanstorpsmodellen. Kommunmodellen consists of variables that explain property prices at a municipal level such as number of citizens, taxes, employme
