There is a shortage of models and analysis methods of fourth generation district heating networks, which are capable of both extracting and depositing heat energy to some thermal network grid. This thesis fills that gap by combining mathematical models of components into a network that is capable of sending heat energy between its nodes. Questions regarding good heating strategies for controlling
Ribonucleotide reductases (RNRs) are important enzymes that convert the building blocks of RNA (NTPs) into building blocks of DNA (dNTPs). dNTPs are used for synthesis of DNA as well as repair of mutated and damaged DNA. These cellular processes are critical to an organism. That is why these processes are found in various organisms. Since these processes are so essential, their allosteric regulati
The aim of this thesis work was to investigate and evaluate new possible industrial applications for large welded plate heat exchangers, with heat transfer areas of at least 500 m2. The research has been carried out through thermal design of heat exchangers for a total of nine cases. The nine cases are real-life applications for processes covering the petrochemical, oil & gas, power, and refin
För att minska miljöpåverkan och minimera exploateringen av de begränsade tillgångar som finns så krävs en övergång till cirkulär ekonomi. Det innebär minskad materialkonsumtion och mer återanvändning och återvinning av plast och andra material. Förra året producerades i världen 359 millioner ton plast och av det insamlade avfallet i Europa blev endast en tred-jedel återvunnet. Bland de fem mest pTo reduce the environmental impact and minimize the exploitation of the depleting re-sources, the transition to a circular economy is vital. It proposes an economy of reduced ma-terial consumption and increased reuse and recycling of plastics and other materials. Only last year, 359 million tonnes of plastic were produced worldwide and only a third of the col-lected waste in Europe was recycled. A
Human biomonitoring (HBM) is a rapidly developing field that is emphasized as an important approach for the assessment of health risks. However, its value for health risk assessment (HRA) remains to be clarified. We performed a review of publications concerned with applications of HBM in the assessment of health risks. The selection of publications for this review was limited by the search engines
In this study, a coupled transient thermomechanical finite element model is developed to examine the laser powder bed fusion (L-PBF) process of the Inconel 718 (IN718) and Oxide Dispersion Strengthened (ODS) superalloys (ODS-IN718). The linear isotropic elastic perfectly plastic constitutive model is implemented for the mechanical part whereas all the thermophysical properties are defined as fully
Due to the large extent of seawater surface over the globe, aerosol particles spend significant time being transported over this type of surface. Therefore, global aerosol circulation is largely impacted by the processes particles undergo during long-range transport overseas. In this study, we investigated submicron aerosol (PM1) chemical composition changes during long-range transport events over

På senare tid har en särskild typ av företag, vars affärsverksamhet går ut på att hyra bostadslägenheter för att vidareupplåta dem till företag som behöver personalbostäder, vuxit fram på hyresmarknaden i Sverige. Detta fenomen är vanligast i storstadsregionerna, företagen brukar kallas för mellanhandsföretag och bostäderna som hyrs ut för företagsbostäder. En av reglerna som aktualiseras vid dennIn recent years, a new category of business has emerged within the Swedish rental housing market, operating by leasing residential flats and subsequently subletting them to companies in need of staff accommodation. This phenomenon is most prevalent in metropolitan areas. Such businesses are usually referred to as intermediary companies, and the flats as corporate apartments. One of the legal provi
Electric cars are by many considered a sustainable solution to the ever-growing demand for road vehicles and fuel. The transportation sector is responsible for almost a third of the total greenhouse gas emissions globally and approximately 80% of these emissions can be attributed to road vehicles. Thus, there is an urgent need for a shift away from fossil fuels in the sector. While the consumer in
The development of electrical circuit boards is increasing and the time spent in the development stage can be quite long. The thesis has tried to shorten the time spent developing new electrical circuit boards, by first finding a common denominator for efficiency losses in the development process and then implementing an example solution. The problem identified was the lack of attention towards pr
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 aim of this master thesis was to develop adaptive control for a quadrotor using Gaussian process regression (GP). Online regression with GPs can provide many benefits as it is a flexible non-linear regression model that can provide uncertainty measures of the estimate. However, online GP regression may also gives rise to problems. Because of the high numerical complexity of GPs, sparse approxi
