Den bästa teorin vi har om den subatomära världen kallas för ”Standardmodellen”. Standardmodellen beskriver de allra minsta partiklarna och deras interaktioner med varandra genom den elektromagnetiska svaga och starka kraften. Genom åren har Standardmodellen förutspått en rad av olika partiklar som har verifierats experimentellt. År 2012 upptäcktes den allra sista partikeln förutspådd av standardmIn this thesis, we extend the Higgs sector of the Standard Model by two scalar singlets and impose a discrete Z2 symmetry on each of them, under which, both singlets are odd. One of the two scalar singlets will acquire a vacuum expectation value while the other one does not. This leads to one scalar field mixing with the SM-like Higgs field and one stable scalar singlet. Thus, three scalar bosons

Barnperspektiv på stadsplanering är inte en modern företeelse, men en väldigt aktuell fråga, inte minst genom att FN:s Barnkonvention sedan den 1 januari 2020 är inkorporerad i svensk lagstiftning. Speciellt Barnkonventionens artikel 12, Om barnets rätt att uttrycka sina åsikter och bli hörd, är av värde för detta examensarbete. Hur ska barn och ungas perspektiv tillgängliggöras i stadsutvecklinge

Vätgas är en energibärare som kan ha en roll i fossilfria energisystem. I det här examensarbetet undersöktes därför den praktiskt genomförbara potentialen för förnybar vätgas att göra nytta i Skånes energisystem inom tidsramen till 2030. Detta analyserades genom en undersökning av de tekniska och regionala förutsättningarna för förnybar vätgas, en intervjustudie med sju skånska vätgasaktörer, samtHydrogen is an energy carrier that could be a part of fossil free energy systems. That is why the practicable potential of renewable hydrogen to benefit the energy system of Scania, Sweden, within the time frame of until 2030 was evaluated in this report. This was done through reviewing the technical and regional conditions and through interviews with seven regional actors involved in hydrogen, as

Jönköping stad har stora framtidsambitioner och hoppas på att staden kan växa i samband med att den nya höghastighetsjärnvägen byggs. För att klara av nya invånare och uppnå de kommunala och transportpolitiska målen behöver kollektivtrafiken byggas ut. Den nuvarande busslinje 1 som är den mest trafikerade linjen i Jönköping idag behöver dras om vid vissa delar för att inkludera den nya höghastigheJönköping city has big ambitions for its future, and they hope that the city can grow with the new highspeed railway. To manage all the new citizens and make up for the communal and transport political goals they need to expand their community rides. Today’s bus line 1, which is the most trafficked line in Jönköping, need a reroute to include the new station for the highspeed trains which will be

In this thesis, alternatives for replacing an RFID card + PIN based access controlsolution for office buildings with a mobile applications are evaluated. The proposedsolutions are based on a probabilistic fingerprinting approach where distributionsof RSSI are approximated and stored in a fingerprint database during an initialoffline phase. Unlike traditional fingerprinting applications, the soluti

As a reaction to our current fast living and increasingly individualistic society, the focus on presence and need for human interaction is rising. With inspiration from Marina Abramovic’s performance work “The artist is present” at MoMa in New York, this project has been focusing on how to create a setting which enhances the interaction between two people. During this project, the aspect of inter

Who hasn’t had a close one who suffered from pain, who hasn’t suffered from pain themselves? It might have been chronic pain, it might have been acute pain or something else. For many of us describing pain can be close to impossible. You might not know the right words to use and try to use metaphors to express the pain you are in, to a doctor. Despite being such a common sensation, pain can be sur

It is impossible to conceive our modern world without plastics. Since the mass production of plastics began, humanity has produced around 8 billion tons of plastic waste, and only 9% has been recycled. Terephthalic acid polymers such as poly(ethylene terephthalate) (PET) have been massively produced over the last years thanks to their characteristics and applications. Due to their limited biodegra

Alfa Laval has been using its unique adhesive mixture for over 50 years for bonding of rubber gaskets to the corrugated plates used in their heat exchangers. The adhesive mix is designated GC6 and is composed out of an epoxy component and a phenolic component. GC6 has throughout the years shown exceptionally good performance in both adhesion to the rubber gasket and to the plate with minimal pre-t

Syftet med den här studien är att bidra med kunskap kring hur medias rapportering av stress - i ett diskursivt perspektiv - ser ut avseende män och kvinnor samt om det finns några skillnader i språkbruk och omfattning. Studien behandlar hur diskursen om mäns och kvinnors stress konstrueras i media, samt om dessa diskurser reproducerar traditionella könsroller som står i konflikt med jämställdhetsm

Utifrån målet att främja psykosocialt hälsosamma arbetsplatser, riktades fokus mot interaktioners kvalitet. Syftet med föreliggande studie var att, med hjälp av the Theory of Planned Behavior (TPB) och dess konstrukt, undersöka de kognitiva förutsättningar som ligger till grund för inkluderande beteenden samt vilka av dessa konstrukt som var mest betydande. Inkluderande beteenden definierades som The present study focused on the quality of interactions based on the goal of promoting a psychologically healthy workplace. Using the Theory of Planned Behavior (TPB) and its constructs, the purpose was to investigate the cognitive conditions that precede inclusive behavior and which of these constructs that are the most important. Inclusive behavior is defined as a prosocial behavior category an

Bebyggelsen från miljonprogrammet utgör en stor andel av det svenska bostadsbeståndet. På flera håll i Sverige börjar dessa bostadsområden bli i behov av omfattande renoveringsåtgärder. Många av dem, framförallt i de större städerna, har med tiden dessutom fått komplexa sociala problem som utanförskap och otrygghet. De huserar till stor del resurssvaga invånare vilket gör frågan om upprustning känThe buildings from the Million Program era make up a large part of the housing stock in Sweden. In many parts of Sweden these areas are in need of comprehensive renovations. Many of them, especially in the larger cities, have developed complex social problems such as segregation and unsafe areas. They house, to a large extent, minorities and people with limited resources. This makes the topic of u

The research area of management control and risk management is relatively novel, especially in the integration aspect of the two. The regulated environment of banks is of interest to this topic due to an already existing high extent of risk management within the organizations. This study uses theoretical foundations of established management control systems and risk management factors, aiming to g

The Bloch beamline on 1.5 GeV ring at MAX IV Laboratory is dedicated to measure electronic structure of materials using the technique angle resolved photoelectron spectroscopy (ARPES) and spin resolved photoelectron spectroscopy (spin-ARPES). The main goal of the thesis is to experimentally determine, the energy resolution of the Bloch beamline at 21 eV and 62 eV as a function of the exit slit ope

Nearly 40 percent of overall energy usage in the European Union is used by buildings and 85 percent of that is for heating and cooling them[4]. This massive amount of energy is thought to be able to be lowered by introducing smarter control of the building systems. Technology to do this is continuously being developed and improved. The newest analysis system developed by Schneider Electric uses cl

The background or idea of this project came from when I was living in Chamonix, France, for two winter seasons where I skied and climbed. During this time, I saw how much humans really do affect the environment. This in turn made me want to investigate what sustainability is and how we, as future designers, can influence this subject. The investigation revealed that the key to a more sustainable
