Rödslam i svenska kraftverk - Problematik och potentiella lösningar

Många vattenkraftverk i Sverige är uppbyggda med dammar som är designade för att läcka en viss mängd vatten baserat på materialet de är byggda med. Flödet av läckagevattnet mäts för att säkerställa dammens funktion, men vid många kraftverksdammar är mätbrunnarna och dräneringsrör fyllda med en rödbrun sörja som kallas rödslam. Rödslammet gör det omöjligt att mäta flödet korrekt, och kan i värsta fMany hydroelectric plants in Sweden are built using dams that are designed to leak a certain amount of water based on the material they are built with. The flow of the leakage water is measured to ensure proper function of the dams, but at several dams the measuring wells and drainage pipes are clogged with a red-brown sludge called Iron Ochre. The build-up of iron ochre is caused by specific bact

Theory of Time-Dependent Transport and Levitons in Nanowires

Levitoner är en typ av strömpulser i metaller och halvledarmaterial som beter sig precis som enskilda elektroner i rörelse.Genom dator simuleringarhar jag studerat hur levitoner uppför sig när de stöter på hinder i sin färdväg. Resultatet av dessa simuleringar indikerar att levitoner behåller sina elektronlika egenskaper även efter att de har passerat genom ett hinder.An interesting type of quasi-particles in solid-state materials are the so-called levitons. These are single- electron excitations above the Fermi-level that do not produce any hole states when carrying an integer multiple of the elementary charge. Levitons are produced when a quantum conductor is subjected to a time-dependent voltage pulse with a Lorentzian shape. The parameters of the voltage pu

The Sustainability Dance: Evaluating Perceptions on Sustainability within Europe’s Electronic Dance Music Sector

Cultural sectors increasingly constitute a larger part of any country’s economy and as such, should be included into sustainability research and analysis. A rapidly growing industry within the cultural sector, this paper examines Europe’s electronic dance music sector as a case study. 13 actors from the sector were interviewed to determine the extent of sustainability’s integration into the norms

No title

This thesis looks into the possible potentials and challenges of the ethnographic comic book, as a way to reflexively present anthropological knowledge and fieldwork experiences. This is explored through the analysis of two anthropological graphic novel projects, Lissa: A Story about Medical Promise, Friendship and Revolution (2017) and Gringo Love: Stories about Sex Tourism in Brazil (2020). Both

Study of Generalizations of the Discrete Bak-Sneppen Model

In 1993, Per Bak and Kim Sneppen proposed a model of co-evolution between species, where survival of a particular species affects the survival of its neighbouring species. In the discrete case of the model, each species, or an entry in a set with periodic boundary conditions, is an element x_i ∈ {0, 1}, in the set of size N, where x_i represents the fitness. An entry of the least fitness is chosen

Behind Boundary Management: a look into Self-leadership and Autonomy when Working from Home

Working from home, previously framed as the same concept as teleworking, is a practice that had already increased in the past decades, but the current health crisis (SARS-2 COVID19) exacerbated the number of home workers all of a sudden (Popovici & Lavinia, 2020). Thus, many workers were forced to manage the boundaries between work and home without experience nor the physical boundary that is

The Visit of an Unexpected Friend

Purpose: The purpose of this paper is to explore the phenomenon of unexpected collaborations between brands. Methodology: This paper follows a qualitative research approach. The research is centered around a multi-case study based on secondary data. In the analysis and discussion, the literature review is applied to the case studies to reveal patterns that lead to managerial- and theoretical impl

Detta med inriktning på juridiska personers möjlighet att få bundenhet till mark i ett tidigt skede i en markexploateringsprocess. Syftet är också att utreda möjligheterna och konsekvenserna i de olika situationer som uppstår beroende på vilken lagstiftninThe purpose of this study is to investigate the possibility for a juristic person to acquire whole or part of a property in an early stage in the land exploitation process in Sweden. The study takes a closer look at the different approaches that a juristic person have at their disposal, one of them being the law called the Land Acquisition Act. The juristic or physical person can apply for an acqu

Lökgrodan i Frihult, Skåne - en statusuppdatering med fokus på chytridiomykos

Amphibians are globally among the most endangered taxonomic groups of vertebrates. This is partly due to the chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes the disease chytridiomycosis, that have led to eradication of more than 90 species of amphibians worldwide. The spadefoot toad (Pelobates fuscus) is one of the Swedish red listed species (VU) that are at risk of being affecte

The Roles of SepF2 and SepF3 in Cell Division in Streptomyces venezuelae

A Tale of Two Proteins: SepF2 and SepF3 You might have heard of antibiotic resistance, which is one of the biggest public health issues of our time. In addition to the measures that should be taken at all levels of society to combat this issue, research to identify new antimicrobial targets to alleviate the rapid emergence of antibiotic resistance has become crucial. Cell division proteins in bac

Studying the Whole Through the Sum of its Parts: Comparing CD8+ Tumour Infiltrating Lymphocytes in Three Types of Human Carcinoma

Cancer är en sjukdom där celler i kroppen för förmågan att dela sig okontrollerat, vilket bildar svulster som påverkar kroppens funktion eller som sprider sig till andra kroppsdelar. Eftersom det är ett stort hälsoproblem så har forskare försökt ta fram nya angreppspunkter mot tumörer förutom metoder som cellgifter, cellskadande strålning eller kirurgi. Immunförsvaret är ett antal olika celler ochBackground: Tumour-infiltrating lymphocytes (TILs) that persist in chronic infections gradually lose their effector functions and become “exhausted”. Immune checkpoint blockade is an emerging cancer treatment which aims to induce exhausted TILs into regaining their effector function to fight neoplastic cells. However, response to treatment varies significantly between different cancer types and ma

SUPPORT VECTOR MACHINE VS. LOGISTIC REGRESSION FOR PREDICTING MORTGAGE DEFAULTS

Mortgage loan providers estimate the credit risks it caries when approving a mortgage loan to their clients. Further, defaulting a mortgage loan is a risk that has been calculated through decades using statistical models. By using entries at the time of a mortgage application, the goal of the thesis is to com- pare the accuracy between logistic regression and Support Vector Machine in predicting

Keystroke Classification of Motion Sensor Data - An LSTM Approach

With mobile phones often being used to type sensitive information, it is important that they remain secure and leak no information. One conceivable channel for information leakage, though, is the motion sensors accelerometer and gyroscope, sensors that require no permission to be used by an app. Do the data they produce contain information about the keys being typed? To answer this question, thi

Title: The EU Way, or the Huawei? A comparative study of the values projected onto Europe’s 5G network by the Chinese Communist Party and the European Union. The purpose of this investigation is to look closer on the value-tension between the European Union and the Chinese Communist Party regarding which values are present in the official policies of these entities and how these values are projec

Abnormality detection in diagnostics data from network cameras

När mjukvara uppdateras och installeras på Axis kameror är det viktigt att hålla koll på om den nya mjukvaran orsakat förändringar i kamerornas prestanda. Förändringarna kan sedan tolkas av en människa, som kan säga om det är en förbättring eller försämring. Genom att ständigt hålla uppsikt över olika metriker (olika prestandamått) hos kamerorna finns möjligheten att upptäcka förändringar som uppsFor data-driven companies, there is a need to efficiently navigate through big quantities of collected data. In our case; detecting changes in the behaviour of data. We have investigated whether machine learning could be applied to automate the process of finding abnormal behaviour (anomalies) in collected data. Some simpler methods were also investigated and compared to the results of machine lea

TRANSFORMING THE ‘80s: Architectural and programmatic strategies for transformation of ‘80s office buildings into housing

The covid pandemic has put light on a trend of office buildings experiencing more vacancy than ever before, given our working habits have been forced to shift from occurring predominantly in an office to mainly being pursued from our private homes. This project foresees a future where working remotely has become the new normal and proposes a residential program in an existing office structure, giv

Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

Sverige står i dagsläget inför en brådskande energiomställning. Fossila bränsle skall fasas ut till 2045, landets kärnkraftsproduktion reduceras stadigt och samtidigt ökar energibehovet i takt med landets elektrifiering. Sverige har dock potential att miljövänligt och självständigt täcka upp för dessa avkall. Tilläget till vind- och solenergi heter Enhanced Geothermal Systems (EGS). EGS-tekniken mThe ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E.ON’s deep drilling FFC-1 in Malmö and data and investigations of the

Integrating Virtual Operations Support Teams (VOSTs) into domestic crisis and disaster management structures – An exploratory study of challenges and requirements for improvement

Social media (SM) use in crisis and disaster management (CDM) is resource-intensive and can overwhelm emergency management authorities (EMAs). Digital voluntarism offers SM capacities for EMAs. A significant approach to reap benefits from digital voluntarism for domestic CDM is introducing Virtual Operations Support Teams (VOSTs). While VOSTs have been proven valuable in increasing capacities, the

Using evidence from the embargo against Qatar to estimate sanctions’ trade effects

While trade policies have been found to promote peace and international cooperation, they are also used in conflicts to punish or coerce the actions and behavior of one’s trading partners. In a globalized world characterized by interconnectivity and complex supply and value chains, their impact and relevance in political conflicts have become even more apparent. Such contemporary developments are
