Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles. These jets could be produced from the proton-proton
Maskininlärning har under senaste årtiondet sett stora framgångar inom en rad olika fält. Grundidén bakom maskininlärning är att istället för att komma på ett smart sätt att lösa något komplicerat problem, så kan man skapa ett datorprogram som lär sig lösa problemet åt en. Sådana metoder för att lösa problem har funnit applikationer inom en rad olika fält, och används inom allt från självkörande bMachine-learning methods have in recent years seen a great deal of use in condensed matter physics. In this thesis we apply such methods, specifically machine-learning with artificial neural networks, to the equilibrium and non-equilibrium description of the Hubbard and Hubbard-Holstein models. In the framework of ground-state density functional theory we reproduce results from the literature rega
Att sälja sin bostad hör till en av livets största affärer. Ett viktigt moment är att bestämma ett utgångspris för sin bostad, men det råder oklarheter kring vilken inverkan utgångspriser har på utfallet i en försäljning. Studien ”List prices in Icelandic residential property sales – A strategic tool for achieving higher sales prices or quicker time-on-market?” tar sikte på Islands bostadsmarknad,In recent years, Iceland has experienced a growing demand for residential housing and the average square-meter price for apartments and single-family homes in the Capital Region has almost doubled between 2010 and 2019. Property sales in Iceland are most commonly intermediated by real estate brokers and the sales process stands in contrast to other Nordic countries, since it involves a bidding pro
Previous research has found that the euro increases FDI flows, yet the evidence of to what extent the EMU membership enhances FDI flows differs between studies. This thesis aims to estimate the impact the financial crisis has had on FDI flows and to further compare the impact the crisis has had on the euro countries to non-euro countries. Bilateral FDI data for both inflows and outflows for the OE

We study a version of the two-envelope problem where a host presents two indistinguishable envelopes to a player. a player is informed that the monetary content of one of the envelopes is twice that of the other and is then allocated one of the envelopes. The player decides whether or not to keep the allocated envelope knowing the content of the allocated envelope and the probability distribution
Rapid Clay Formations (RCF) is an ongoing research project investigating robotic aggregation of soft clay elements. This thesis presents our research into RCF construction on an architectural scale. It outlines our development of a fabrication process suitable for the construction of tall and slender structures made out of clay. This fabrication process is evaluated through a series of prototypes
Antimicrobial resistance is according to the World Health Organization (WHO) one of the most rapidly growing threats to world health. According to a recently published WHOreport, drug resistant microbials could be responsible for up to 10 million annual deaths by the year 2050 unless drastic measures are taken such as decreasing misuse and developing new antibiotics. This work explores the possibi
Matrisfunktioner och deras applikationer spelar en viktig roll inom olika vetenskaps- och teknikområden. Matrisexponentialen är en av de viktigaste och mest använda funktionerna av matriser. Beräkningen av exponentialen av en matris är ett intressant ämne som har studerats mycket genom åren. Det finns flera sätt att beräkna matrisexponentialen men det är en utmaning att hitta vilken metod som är bMatrix functions and their applications play an important role in different fields of science and engineering. The matrix exponential is one of the most important and extensively used function of matrices. The computation of the exponential of a matrix is an interesting topic that has been extensively studied over the years. There are several ways computing the matrix exponential but there is a pu
Sociala medier är idag ett självklart inslag i många människors liv, och deras utrymme i samhället fortsätter att expandera. Vår självkänsla är viktig för vår psykiska hälsa då en bra självkänsla fungerar som ett slags “psykologiskt vaccin” mot psykisk ohälsa. Med detta som bakgrund är det tydligt att det är ett viktigt fokus att bygga på den forskning som redan har undersökt sambanden mellan sociA lot of people are using social media today, and the usage is continuously increasing. Our self-esteem is important for our psychological health since it works as a “psychological vaccine” against psychological ill-health. With this being said it is clear that it is important to add to the research that has already been done regarding the correlation between social media usage and self-esteem. Th
A bachelor project in the course studio: Contemporary Architecture, at Lund School of Architecture. The aim of this course was to develop spatial and structural typologies through experimentation with the digital design process. The main focus has been to manage computer modeling with Rhinoceros and Grasshopper.
Elektrifieringstrenden inom transportsektorn tycks under hösten ha lämnat marken; elflyg anses vara ett av svaren på hur luftfarten skall reducera sin omdebatterade klimatpåverkan i framtiden. En ökning av tunga elektrifierade fordon, inklusive flyg, resulterar i konsekvenser för elsystemet sett till ökat effektbehov och nya lastprofiler. Examensarbetet ämnar således undersöka vilken roll regional
Ökengräshoppan är ett väldigt litet djur men de kan skapa stora problem när de ökar i antal och samlas i svärmar. Plågorna från dessa är kända sedan bibliska tider men med ett utbrott så sent som 2020 så är ämnet lika relevant idag. Gräshopporna utgör ett hot mot jordbruk, och i förlängningen tillgång till mat, genom sin stora aptit, varierade kost och förmåga att förflytta sig långa sträckor. DetThe knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. More knowledge of the aftermath is required by the international d
Fordonsindustrin elektrifieras just nu i en snabbare takt än någonsin. Allt från elektriska cyklar till Segways och elektriska longboards. Alla dessa kräver nya sorters interaktioner för att styra motorn. Segway har till exempel utnyttjat användarens lutning som ett medel för att bestämma om personen vill åka fram eller bak. Elektriska longboards använder sig ofta av en handhållen kontroll med en The automotive industry is now electrifying at a faster rate than ever before. Everything from electric bikes to Segways and electric longboards requires new kinds of interactions to control the engine. For example, Segway has used the user's tilt to decide whether they want to go forward or backward. Electric longboards often use a handheld controller that has a gas button. Now, this electrif
The discovery of penicillin and the many antibiotics after that, has given our society a heightened sense of confidence when dealing with everything from the everyday bacterial infection to complicated surgical procedures. However, more and more bacterial species are becoming resistant to antibiotics. 33000 deaths attributed to antibiotic-resistant bacteria occurred in Europe in 2015, a number tha
