För att möjliggöra omställningen från fossila kolväten har bioolja identifierats som ett viktigt verktyg. Bioolja refererar till ämnen med liknande egenskaper som traditionellt petroleum, men som produceras genom kontrollerad förbränning (pyrolys) av jord- och skogsbruksavfall. Bioolja har stor potential, eftersom dess kemisk-fysikaliska likhet till de fossila kolväten som redan används som bränslAn important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. To optimise such processes, a thorough understanding of the catalyst is required. Spark discharge generation (SDG

The purpose of this master’s thesis is to illuminate the information practices of professional musicians in the field of Early music. These musicians have a special interest in exploring the performance practices of the time periods when the music was composed, to make it more vivid in the present. This more and more widespread approach to Early music is called Historically Informed Performance (H

Nyligen har preliminär forskning funnit att personer med självskadebeteende och andra psykiatriska diagnoser verkar ha en lägre funktionsnivå avseende grundläggande självomhändertagande aktiviteter, jämfört med personer med psykiatriska diagnoser men utan självskadebeteende. Anledningarna till detta har dock inte studerats i tidigare forskning. En explorativ kvalitativ forskningsstudie med en kritRecently, preliminary research has suggested that people with deliberate self- harm (DSH) and other psychiatric disorders have a lower functioning regarding fundamental self-care activities, compared to people with psychiatric disorders but without DSH. However, the reasons for this have not been studied in previous research. An explorative qualitative research study with a critical realist approa

Följande studie är en fallstudie på fastighetsdigitalisering ur ett ägarperspektiv. Studien är genomförd för att uppfylla två områden. Del ett är att klargöra den klimatkris som vi står inför och fastighetsbranschens andel i den krisen. Del två är att redovisa hur fastighetsdigitalisering utvecklas, används och hur den kan hjälpa till att optimera fastigheter och fastighetsföretag. Studiens syfteThe following study is a case study on real estate digitization from a real estate owners’ perspective. The motivation for the study is two-fold: first the ongoing climate crisis, and second, the ongoing digitalization development in real estate and real estate business. The purpose of the study is to explore the digitalization of Swedish real estate companies with a focus on the ownership persp

Ökad undersökningsdjupet i magnetomotoriskt ultraljud med hjälp av ett homogent magnetfält. Medicinska bilder spelar en stor roll för att ställa diagnoser och styra terapi. Olika discipliner som radiologi, endoskopi eller mikroskopi används för att skapa bilder på människan, alla med olika syften. Diagnostiskt ultraljud är en av dessa bildgivande metoder. En så kallad prob sänder ut ljud i olika Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. The technique has applications in cancer detection but is limited in penetration as the magnetic field decreases rapidly with distance. Instead of increasing

When being in a noisy environment, a normal hearing person can manage to sort out background noise and focus on the attended source. This is something that a person with impaired hearing will struggle with, even when wearing a hearing aid. Research for developing intelligent hearing aids has not yet come up with a solution for solving this problem and more research is needed. This thesis uses data

Vilka hinder och drivkrafter för klimatanpassning står större fastighetsbolag inför? Hur väl rustade är fastighetsbolagen för att hantera ett framtida klimat? Den frågan blir mer och mer aktuell då det är tydligt att samhället behöver anpassas till ett förändrat klimat oavsett om vi uppnår Parisavtalet eller inte. Redan idag ser vi tydliga konsekvenser av klimatförändringarna med bland annat en öThe consequences of climate change are already affecting the built environment and adaptation to these effects must be addressed by both public and private actors. In Sweden private actors have an important role to play as they are responsible for addressing their climate adaptation or accept the consequences. The purpose of this thesis is to study the barriers and opportunities for large private

In this text we continue the work of describing subalgebras of K[x] of finite codimension that was started in Describing subalgebras of K[x] using derivatives. In the referenced paper, the authors present how univariate subalgebras can be described by conditions based on evaluations in certain scalars, and proceed to develop a large theoretical framework to understand the nature of such conditions.

This thesis aims to further investigate the viability of using reinforcement learning, specifically Q-learning, to schedule shared resources on the Ericsson Many-Core Architecture (EMCA). This was first explored by Patrik Trulsson in his master thesis Dynamic Scheduling of Shared Resources using Reinforcement Learning (2021). The shared resources complete jobs assigned to them, and the jobs have d

I Sverige är grundvatten är en av de huvudsakliga källorna för dricksvatten. Grundvattenmagasin kommer att påverkas av klimatförändringar genom förändrad effektiv nederbörd och således grundvattenbildning. Dessa vattenresurser ska finnas kvar för framtida generationer och det är därför av vikt att studera dem samt öka förståelsen kring dem. Sveriges miljömål kring grundvatten nämner ett behov av aIn Sweden groundwater is one of the primary sources for drinking water. Groundwater reservoirs will be affected by climate changes with changes in effective precipitation, which means changes in groundwater recharge. It is therefore of value to study and examine these water resources, so that they remain just that for the generations to come. Sweden’s environmental goals regarding groundwater sugg

Since its first publishing in 1954, The Lord of the Rings has been read by millions, and it has become the subject of many scholarly studies. However, one of its most famous characters, Gollum, has only been marginally examined. The aim of this essay is to counteract precisely that and examine how Gollum exists within, and in his own way embodies, the theological and moral system of The Lord of th

The marine environment is a vital resource protecting our ecosystem and a critical part of the wellbeing of our planet. Marine Strategy Planning (MSP) is essential for conservation and protection of marine monitoring systems and governments should constantly improve their strategies and aim for increased effectiveness of these systems. This thesis focuses on marine conservation in Sweden and revie

Rare books, defined in this study as books printed or written before 1850, can be found at the Swedish municipal archives but are not necessarily a part of the traditional archival material. Due to the fact that rare books are not protected by law, the municipal archives can work and think differently about the rare books’ preservation, availability and value. There are several studies on the subj

The Pan-Tilt-Zoom (PTZ) camera is a type of camera that covers large areas, up to 360°, in addition to zoom. Some of these cameras are susceptible to tampering, which means that an additional angle measurement feedback is necessary to detect such attempts. This thesis has evaluated the possibility of using MEMS-based IMUs to solve this problem. An advantage of such a system over other solutions, s

In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. We use Pythia and Delphes for event generations and detector simulations, and consider both pp and e+e− collision events at 13 TeV. The kinematic studies are based
