Wind energy is one of the fastest growing renewable energies in Sweden. To support this growth, it is essential to give stakeholders, such as investors, municipalities and policy planers, access to high accuracy and high-resolution wind speed data. Essential components for an accurate wind energy potential prediction are the average long-term wind speed and the probability of occurrence of wind

In this thesis project I investigate, analyze and develop a proposal in order to improve the urban qualities of my hometown, Visby on the island Gotland in the Baltic sea. The city had a major role as a trading port during the 12th and 13th centuries but then had an economic setback which hindered its growth until the19th century. The medieval street network of the old city as well as the old city

Vatten, både i flytande- och fast form, anses vara en av de stora riskerna till uppkomst av skador på vägar. Det kan nå vägkonstruktionen redan under byggskedet eller i ett senare skede, vilket ställer stora krav på att hålla det borta från vägkroppen för att eliminera risken för uppkomst av följdproblem. En väg genomgår tre viktiga faser, Projektering, Produktion samt Drift- och underhåll. BristfWater, both as a liquid and solid, is considered to be one of the major hazards that can give rise to damages on the road. It can affect the road during the construction stage but also at a later stage, which places a great demand on keeping water away from roads in order to eliminate the risks of secondary problems. A road goes through three important stages, Design, Production, Running operation

Terra sigillata is a roman pottery type that was primarily produced in western Europe during the period between first century and fourth century AD. This pottery, as well as other objects imported from the Roman Empire, can perhaps show trading routes between societies in Scandinavia and societies in Europe. Accordingly the aim of this essay is to distinguish possible trading routes that have been

The ATLAS@Home project is a volunteer computing project, part of the larger LHC@Home project, aimed at using the computational power of personal computers from volunteers around the globe, who are interested in helping with the particle physics research taking place at the ATLAS experiment at LHC. Up this point it runs only ATLAS detector simulation tasks. This thesis explores the possibility of h

På grund av människans aktiviteter har många av världens vattenresurser förorenats. Dricksvatten förorenat av arsenik, en tungmetall som kan orsaka akut förgiftning och en uppsjö av sjukdomar, blir allt vanligare världen över. I och med detta ökar behovet av sätt att detektera och oskadliggöra tungmetaller och även olika typer av skadliga kemikalier i våra vatten. Tänk dig ett system där bakteriMany of our freshwater resources are contaminated with pollutants such as heavy metals and organophosphates, and therefore the demand for reliable and efficient methods for detection and remediation of such pollutants is increasing. One widely used method for remediation of water is through the use of engineered communities of microbes that have the ability to degrade or make the contaminating com

The amount of wind turbines in Sweden has more than doubled in the last five years. Wind turbines can affect birds directly, by causing fatalities and indirectly, through habitat destruction, disturbance and barrier effects resulting from turbine construction and operation. To increase understanding of how this rapidly expanding form of energy harvesting affects avian communities in Sweden large,

Duni has successfully expand their business internationally. Internationalization makes the distance between the producer and consumers become longer and this leads to strength reduction of corrugated boxes along the supply chain. To overcome this problem, this study is conducted to find the extent of corrugated boxes strength reduction during logistical activities, practices and condition in the

The development of today’s energy-efficient dwellings often results in highly technical building solutions. We try to shield ourselves and our buildings as much as we can from the outdoors and subsequently loose an essential connection to the elements. Traditional design principals fall into oblivion and high-rise glass towers are justified with technological progress. By implementing selective st

Rapsfält – ett överflöd av mat eller en gul öken för vilda bin? Gula rapsfält har blivit en allt vanligare syn under försommaren i Sverige, ett hav av gula blommor rika på både pollen och nektar. Samtidigt går det allt sämre för de vilda bina världen över och många frågar sig om inte raps kan tänkas hjälpa de vilda bina på traven att förhindra att bina blir ännu färre. För utan bin förlorar vi enPollinators are important for both the agricultural landscape and natural areas, but currently many pollinator groups are declining. Pollinators have a strong relationship with plants, which humans long have benefited from. Nowadays, 35 % percent of the human food production somehow relies on animal pollination. Therefore, unravel the details about crop pollination and its relationship to differen

Urbanisation in Beirut has led to a situation where the city suffers from a severe lack of green public space—Lebanon’s capital have ended up with some of the least amount of public green space per capita in the world. The lack of green surfaces and vegetation in Beirut contributes to the city’s Urban Heat Island (UHI)—a phenomenon where an urban or metropolitan area traps waste heat and end up si

Air pollution has become a major worldwide concern due to the high levels of air pollutants emitted from industrial and traffic related activities. Exposure to air pollution has been linked to various negative health effects, ranging from asthma to chronic illnesses. Consequently, analyzing air pollution data has become an essential tool for giving insight about the potential health effects. Spati

De två Natura-2000 områdena Ravlunda och Revingehed i Skåne, södra Sverige, har genomgått en klimatkänslighetsanalys i denna studie som testade en utvärderingsmetod för relevans att använda inom Länsstyrelsen i Skånes arbete. Analysen gjordes med fokus på ekosystemtjänster identifierad för sanddominerade habitat på de två områdena. Genom användning av en nyligen publicerad report från NaturvårdsveThe two Natura-2000 areas of Ravlunda and Revingehed of Skåne, southern Sweden, have been subject to a climate change vulnerability assessment in this study, which tested an assessment method for relevance for work within the County Administrative Board of Skåne. The analysis was done with focus on ecosystem services found at the sand dominated habitats of the two areas. Using a recently published

Möllevången is a fascinating study of a neighborhood that has undergone significant change and transformation over time. Historically, the area was known for its working-class roots, with crowded narrow streets and traditional Swedish homes; but in recent decades the area has seen waves of gentrification and redevelopment, resulting in a mix of a new and old built environment that has made it one

The floating population, also known as rural-urban immigrants, is a typical type of domestic migration appearing in the process of urbanization in contemporary China. Due to the policy restrictions, the Floating population is in a disadvantageous position and lacks social security. Though the ultimate goal for many domestic immigrants is to transform into urban residents, the biggest challenge t

The digital platform Airbnb has gained popularity in a number of countries particu- larly in the Maltese islands. Striking a balance in setting a price that is competitive and also renders a good profit can be a challenge. In this thesis a model is de- veloped to predict the price of a listing in the Maltese islands for September 2022 through a machine learning approach whereby five types of model

Skogsbränder hotar bevarandet av skogens ekosystemtjänster såsom ekologiska funktioner för biologisk mångfald, mildring av effekter från klimatförändringar och rekreation såsom skogspromenader och bärplockning. Hur kan vi ingripa för att återhämta och bibehålla sådana funktioner i naturen efter bränder? I den här studien undersöktes potentialen för återhämtningen av skogar utifrån skogsåtgärder efWildfires causes natural disturbances to ecosystems which can have potentially damaging results for ecosystem services and economic income from timber production.
