The thesis treats the subject of risk and vulnerability analysis of large-scale technical infrastructures. In particular the focus is on the development of methods for vulnerability analysis of electrical distribution systems. The methods and the concepts behind them should nevertheless also be seen as applicable to other technical infrastructures. Robust and reliable technical infrastructures are

The report compiles the results from the METRO-project. The different parts of the project; design fires, evacuation, integrated fire control, smoke control, extraordinary strain on constructions and fire- and rescue operations are presented separately. The most complicated and expensive part of the project was the performance of the large scale fire and explosion tests in the Brunsberg tunnel. T

The book "Aqua-ecologic Functional Zoning of Songhua River Basin: Application Manual" introduces the technical methodology and detailed application instructions for aqua-ecologic functional zoning in Songhua River Basin in a systematic way in nine Chapters. Based on a general introduction of concept and in-depth contents of aqua-ecologic zoning and its methodology, this application manual addresse

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, generates a large amount of waste heat. Some of this heat is partially recovered and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This work studies in detail four different solutions to utilize t

The borehole thermal resistance – that is, the thermal resistance between the fluid in the U-tube and the borehole wall – is both a key performance characteristic of a closed-loop borehole ground heat exchanger and an important design parameter. Lower borehole thermal resistance leads to better system performance and/or lower total borehole length and possibly lower installation costs. Borehole th

Higher Education in the European context has been transformed radically since 1990s, partly in line with global political and economic trends. In the Swedish context these trends also manifested itself, among other things, in how teaching is practiced and valued. The managerial and paradigmatic shift altered the balance between teaching and research in the favour of the latter. This happened while

Traditional knowledge (TK) is in simple terms knowledge systems held by indigenous communities, often relating to their surrounding natural environment. Through globalisation and the increased availability of this knowledge as well as the implementation of intellectual property systems in the developing world TK and its relationship with the IPR-system has become a much debated and highly complica

The aim of this master thesis is to study how the development of a public library by means of ideas and methods from the private sector can be related to traditional core values. We base our study on institutional theory, which focuses on norms and values in an organisation, and new institutional theory, which focuses on how organisations are influenced by changes in the environment. We also use N

Detta examensarbete är gjort i syfte att undersöka gröna tak som en alternativ taktäckning. Vi har undersökt de vanligaste orsakerna till varför gröna tak väljs bort, fördelar med gröna tak samt dess konstruktion. Gröna tak har funnits i olika former sedan 900-talet före Kristus. Då bestod takträdgårdarna till största delen av träd, buskar och klängväxter i krukor. I Skandinavien byggde man många This thesis is made in order to review green roofs as an alternative roof covering. We have studied the common sources why green roofs are not selected and its advantages and construction. Green Roofs have existed in different shapes since year 900 before Christ, when the gardens were built up with trees, bushes and climbing root in pots. In Scandinavia, many centuries later, roof coverings were m

Due to the change in climate the design flow for Bergeforsen dam, located at the Indalsälven river mouth, is being revised from 2300 m3/s to more than 3000 m3/s. The dam needs to be upgraded with a new gated spillway and repaired in order to increase the safety of the dam. Concerns have been raised about the altered flow conditions that will occur downstream of the dam in connection with that the

The purpose of this master's thesis is to examine whether music formats, as well as social media and apps, has affected how people dedicated to music search for music – and how this relates to the master's thesis theoretical aspects, as well as previous research about music information-seeking and -retrieval and the significance of tactile attributes. This will also be put in a library con

Purpose: Although persistent offenders with histories of imprisonment and violence have disproportionate high rates of psychiatric disorders, little is known of their psychiatric healthcare utilization (HCU) and HCU-associated factors. This study aimed to explore psychiatric HCU, psychiatric morbidity, and psychotropic prescription drugs in violent offenders with a history of incarceration. Method

Soil pore space, considered the most complex biomaterial that exists, generates a complex environment, that gives rise to a wide variety of properties, such as microbial diversity and carbon storage. Soils contain, at the same time, the largest carbon reservoir on earth and an immense amount of nutrient-limited microbial biomass. The reason why this carbon is not consumed by soil microbes is attri

Background: People with intellectual disabilities (ID) may be at higher risk of psychiatric disorders than the general population. However, few studies investigate the role of demographic factors.Methods: This register-based study includes all people living in Skåne, Sweden, on January 1st, 2014. The ID cohort comprises those who received support and service for people with functional impairments

The resettlement and integration of a displaced population into a new society faces a plethora of challenges. These range from lack of national legal frameworks to plan and implement planned relocation, to the absence of a long-term vision, inadequate funds, and poor institutional structures. The 3-year EU Erasmus+ funded REGARD Project (REbuildinG AfteR Displacement) set out to address some of th

Background: Cyanobacterial blooms are of increasing concern for drinking water supply. In Sweden, a survey among drinking water producers showed that the sense of urgency was little. At 60% of the Swedish drinking water treatment plants, operators lacked monitoring strategies. To get a picture of the size of the problem the presence of cyanobacterial risk in 108 Swedish lakes was evaluated from 23

With the emergence of industrialisation, the work-life balance has become a point of discussion in many industries, among which the aviation industry. Distortions in the work-life balance became especially apparent when 24/7 economies evolved, and industries made a transition to facilitate and serve these economies. Incidents and accident have since then been related to fatigue more than before. T

In this thesis, it is investigated how the general public and fire safety experts perceive the fire fatality risk of different socio-demographic factors in residential settings. Their perceptions were compared with how the socio-demographic factors correlate with the risk of fatal fires in residents in reality. The purpose of this work was to find out where resources need to be directed and who ne

Sett till EU:s totala koldioxidutsläpp står byggnadernas energianvändning för en tredjedel av dem (Regeringskansliet 2023). Sverige har ett energipolitiskt mål om att ha en 50 % effektivare energianvändning till 2030, jämfört med 2005, benämnt energiintensitetsmålet. En stor del av den befintliga bebyggelsen i vårt samhälle har ett högt energibehov. Med ökade krav på energieffektivisering av det bOne third of the EU's carbon emissions come from buildings energy use. Sweden aims for 50% more energy efficiency by year 2030, compared to year 2005. Existing buildings, with high energy demands, require renovations for energy efficiency. However, it is crucial to consider the climate impact of such upgrades. Window renovations are one option. This study explores the complexities of improving
