A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. The unit cell which is repeatable in alThe transport of heat from hot to cold mediums is called heat transfer. It can be used for either heating or cooling machines, electronics food, etc. in industry. Examples are the cooling of a car engine or recovering heat from a power plant turbine. In these types of applications, it is practical to use fluids of high heat capacity as mediums for transferring heat as this means they that they are

We propose a novel, real-time algorithm for recoloring images to improve the experience for a color vision deficient observer. The output is temporally stable and preserves luminance, the most important visual cue. It runs in 0.2 ms per frame on a GPU.

De globala hållbarhetsmålens koppling till klimatanpassning i svenska kommuner Denna studie visar på att klimatanpassningsåtgärder i svenska kommuner bidrar till nyttoaspekter som kan kopplas till Förenta nationernas globala hållbarhetsmål. Dessa mål kan även vara ett bra verktyg för kommuner att använda sig av för att uppnå olika sociala, miljömässiga och ekonomiska värden vid framtida klimatanpaThis study shows that several beneficial aspects of climate adaptation in Swedish municipalities can be linked to the United Nations’ sustainable development goals. In doing so, the study also exhibits that the sustainable development goals could serve as a good tool to aid in maximizing social, environmental and economic benefits when planning and executing climate adaptation measures.

This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. The effect of these

N-(9-fluorenylmethoxycarbonyl)-diphenylalanine (Fmoc-FF) is a combination of two phenylalanine amino acids connected by a peptide bond and protected by a Fmoc group. This dipeptide exhibits unique self-assembly properties, forming a variety of structures such as nanofibers, nanotubes, and hydrogels. The aim of this project is to investigate the structure and phase behaviour of self-assembled Fmoc-

The continuous advancement of photorealism in rendering is accompaniedby a growth in texture data and, consequently, increasing storage and memory demands. To address this issue, we propose a novel neural compressiontechnique specifically designed for material textures. We unlock two morelevels of detail, i.e., 16× more texels, using low bitrate compression, withimage quality that is better than a

Circular Economy (CE) is seen as a potential solution to sustainability challenges (eg. global warming), but companies lack guidance in adopting these strategies. The study addresses the need for a unified methodology to assess and prioritize CE strategies at the organizational level. The research integrates social dimensions (social CE indicators and Social Organizational Life Cycle Assessment (S

Denna studie syftade till att undersöka vilka argument de boende i Nørrebro tillämpar i förhållande till användningen av visitationszoner i Danmark, samt hur dessa argument kan tolkas utifrån relevanta sociologiska teorier och tidigare forskning. Bakgrunden till studien är det eventuella införandet av visitationszoner i Sverige och den diskussion som uppstått angående dess effektivitet i arbetet m

Denna uppsats utgörs av en kvalitativ intervju studie, som med utgångspunkt i Polismyndighetens strategi för arbete i utsatta områden (Polismyndigheten, PM 2018:26) utforskar hur anställda inom Polismyndigheten beskriver och uppfattar samspelet mellan relationsskapande och gränssättande arbete i socioekonomiskt utsatta områden. Vidare syftar undersökningen till att analysera hur intervjuade polise

Synthetic methods for making an all-silica MCM-41 mesoporous silicate of high long-range order are reported. The product shows up to seven orders of X-ray diffraction and good stability under calcination conditions. The greatest improvement in structure occurs when the pH is held between 9 and 10 during synthesis and the sulfate anion is present.

Synchrotron X-ray diffraction patterns for highly crystalline MCM-41 a mesoporous silicate molecular sieve are presented. The form factor observed in seven orders of diffraction is used to show the existence of a two-layer wall structure, with a narrower mesopore than previously assumed, and much void space in the walls.

Orientational ordering under shear was observed for some precursor gels for the synthesis of the hexagonal mesoporous silica MCM-41 in the presence of high KBr concentrations. The presence of KBr disrupted the formation of the first-order MCM-41 diffraction peak dependent upon KBr concentration. Synthesis gels which formed good quality MCM-41, but with no added KBr salt, were not oriented by stron

The goal of this thesis work is to describe the methods used and perform comprehensive testing of the Double-Sided Silicon-Strip Detectors (DSSD) prior to their implementation in the Lund-York-Cologne CAlorimeter (LYCCA) detector. In the framework of this project, the DSSD characterisation was carried out to ensure specification compliance prior to their "in-kind contribution" delivery t

Sammanfattning Under slutet av 1960-talet genomgick bostadsmarknaden och lagstiftningarna som hör till en stor förändring. Däribland skärptes hyreslagen med fler krav på underhåll och fastighetsskötsel, och en utredning föreslog att grov vanvård ska vara en grund för expropriation. Under 1969 kom även en utredning angående att införa en lagstiftning som möjliggjorde tvångsförvaltning av fastighetAbstract The Housing Management Act (1977:792) enables compulsory management of properties that are neglected. However, the law can only be applied to tenements. In the year of 2021, the law underwent an amendment, which came into force on January 1, 2022. In all forms of housing that are in an apartment building, have common areas and constructions that require joint management. The purpose of t
