This thesis outlines the design and construction of an acoustophoretic trapping device with greatly increased capacity and throughput, compared to current commercial systems. In acoustic trapping, a strong, localised acoustic field is generated inside a channel. This field can capture and retain particles against a flow, allowing for nanoparticle purification and enrichment without the need for ul
Many premature deaths and health problems could be prevented by adhering to a healthy diet, however, many people lack the self-regulation needed for maintaining healthy behaviors. Goal-conflicting situations (i.e., when a person needs to decide between one of two conflicting goals) are an obstacle for self-regulation, while coping planning is found to be useful in these situations since it entails
This study evaluated the sample sizes necessary to estimate several soil and vegetation characteristics within 10% confidence intervals with 95% probability in three terra firme tropical rainforest sites. Across all three plots, the most spatially heterogeneous variables were measurements of total standing crop root mass, ground surface litter mass, litter fall, root growth and soil respiration wh
This paper evaluates whether a deep reinforcement learning (DRL) approach can be implemented, on the Swedish stock market, to optimize a portfolio. The objective is to create and train two DRL algorithms that can construct portfolios that will be benchmarked against the market portfolio, tracking OMXS30, and the two conventional methods, the naive portfolio, and minimum variance portfolio. We eval
Applied Machine Learning in Steel Industry – Examination of possible applications of machine learning for SSAB Oxelösund In modern industry there are high demands for increased resource efficiency that in part are motivated by the stronger competition on the global market, as well as by the societal necessity for a more sustainable industry. This master thesis project examines applied machine lear
The Alps are undergoing constant landscape changes due to modern socio economic changes. Especially grassland ecosystems of alpine meadows and pastures are threatened by the slow abandonment of the alpine transhumance traditions. This influences not only biodiversity but also the important cultural landscape seen as a valuable heritage in the Alps. The landscape in the North Italian alpine provinc
The onset of Earth's present icehouse climate in the Late Eocene coincides with astronomical events of enigmatic causation. At similar to 36 Ma ago the 90-100 km large Popigai and Chesapeake Bay impact structures formed within similar to 10-20 ka. Enrichments of He-3 in coeval sediments also indicate high fluxes of interplanetary dust to Earth for 2 Ma. Additionally, several medium-sized impact st
Context: When using the Case Method in teaching situations, problem-solving is emphasized and taught, in order to acquire the skills and later be able to apply them in new situations. The basis of the learning process is the students’ own activity in the situation and is built on critical appraisal and discussion. Objectives: To explain what the Case Method is, what it is not and to describe when
The effect of the anionic surfactant SDS (sodium dodecyl sulfate) on the adsorption behaviors of cationic hydroxyethyl celluloses (Polymer JR-125, JR-400, and JR-30M) and hydrophobically modified cationic cellulose (Quatrisoft LM-200) at silica surfaces in the presence of a 10 mM NaCl solution has been investigated by null ellipsometry. The adsorbed amount of LM-200 is found to be considerably lar
Fed aquaculture is a necessary practice to meet the seafood requirements of a growing population in a sustainable manner. There is a high demand for fish feed to meet the rising protein requirements of the industry. Currently, fish feeds are either unsustainable, affected by seasonal variations, lack a complete amino acid profile, lack scalability, or are too expensive. Single Cell Protein (SCP) i

Brottsbekämpande myndigheter står inför allvarliga prövningar till följd av den gränsöverskridande organiserade brottsligheten. Detta har resulterat i en ambition om effektivisering av brottsbekämpningen, inte minst genom okonventionella utredningsmetoder som provokativa åtgärder. Betydelsen av det internationella straffrättsliga samarbetet har dessutom ökat. Brottsbekämpningen och samarbetet centLaw enforcement authorities are facing serious challenges as a result of cross-border organized crime. This has resulted in an ambition to make law enforcement more effective, not least through unconventional investigative methods such as provocative measures. The importance of international criminal justice cooperation has also increased. Law enforcement and cooperation often focus on encrypted c
Instead of investing 145 billion SEK in building a new high speed rail network, much greater value in terms of transport capacity is likely to be found in constructing a new system of tube transport with a travel speed of 600 km/h. The suggested technology does not exist yet. However, research and development is advancing and accepting that a new technology is emerging might be the greatest hurdle
Parkinson’s disease (PD) patients frequently develop cognitive impairment. There is a need for brief clinical assessments identifying PD patients at high risk of progressing to dementia. In this study, we look into predicting dementia in PD and underlying structural and functional correlates to cognitive decline in PD. We included 175 patients with PD, 30 with PD dementia, 51 neurologically health
There is a growing interest in organized self-help housing (OSHH) from both authoriti es and Non Governmental Organizati ons (NGOs) working in the housing sector due to the magnitude of housing problems in developing countries and the challenge of achieving sustainable humansett lements. This paper focuses on the experiences of two NGOs, FUPROVI in Costa Rica and SADEL in Sweden, in facilitati ng
Det ökande byggandet av stadsvägtunnlar, de alpina tunnelolyckorna runt millennieskiftet, och det efterföljande EU-direktiv (2004/54/EC) med minimikrav gällande brandsäkerhet har placerat brandsäkerhet i vägtunnlar högt på dagordningen. Samtidigt är moderna enkelriktade vägtunnlar ofta bland de säkraste delarna av vägsystemet. Har vi kommit till en punkt där resurserna används bättre någon annanstThis thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. The safety journey naturally started out with the traditional view, with fire safety engineering based on limit-based design. Using this paradigm the sa
The prevalence of anastomotic strictures in esophageal anastomoses provides us with limited information about the anastomotic healing process. This prospective study evaluates the exact esophageal anastomotic diameters in 256 patients who underwent esophagectomy and esophagogastrostomy without pyloroplasty (n = 107) or total gastrectomy and Roux reconstruction (n = 149). No perioperative chemoradi
We determined the concentration of markers in cartilage and synovium metabolism in the synovial fluid (SF) of the knee of young beagle dogs with slowly progressive osteoarthrosis. Osteoarthrosis (OA) was induced by a tibial 30°valgus osteotomy to the right hindlimb of 16 dogs. The contralateral knee served as control. The animals were killed 7 (group I) and 18 months (group II) after operation. Th
