This master’s thesis is commissioned by SAAB Group with the purpose of developing a model which can be used to estimate the margin for expansion of devices in PLC systems. Although commercial PLC systems are hard real-time systems, they have inherited unpredictable characteristics due to off-the-shelves components. This makes it difficult to measure the impact on performance when a new device is c
In this master thesis a novel way of trapping nanosized particles were tested. The technology used was based on acoustic trapping with seed particles. In difference to earlier devices the seed particles were held in place by a physical barrier that worked like a filter, stopping the bigger seed particles while allowing the nanosized particles to flow through, a setup that allowed for significantly
The diffusion equation is a partial differential equation that describes how quantities such as heat, particles, or other diffusive substances spread out over time and space. This type of equation can be, at often times, quite challenging to solve analytically. Finding the exact solution is often difficult due to the com- plexity of the functions involved. This thesis focuses on solving the diffus
Grass pollen allergens, including Phl p 5 from Phleum pratense, are major triggers of seasonal allergic rhinitis, primarily mediated by IgE antibodies. This study investigates the genetic basis and functional characteristics of IgG1 antibodies targeting Phl p 5, possibly derived from type 2 memory B cells predisposed to IgE switching. Using site-directed mutagenesis, we analyzed variants of a high
Simulating the behavior of charged particles in linear accelerators requires calculating the effects of electromagnetic fields on the particles. One source of these fields is the particles themselves, through the so-called space charge self-field. To compute this field, the Poisson equation must be solved using the charge distribution of the particle bunch. In most cases, this cannot be done analy
Denna avhandling, genomförd i samarbete med Robert Bosch AB, undersöker gestbaserad interaktion med Smart Connected Sensor Platform (SCSP), med fokus på köns- och spelbakgrundspåverkan, användarens förståelse för SCSP kapabiliteter samt effektiviteten av gamification och Wizard of Oz (WoZ) testtekniken. Forskningen använde en iterativ designprocess och utvecklade lo-fi pappersprototyper samt en inThis thesis, conducted in collaboration with Robert Bosch AB, investigates gesturebased interaction with the Smart Connected Sensor Platform (SCSP), focusing on gender and gaming background influences, user understanding of the SCSP’s capabilities, and the effectiveness of gamification and the Wizard of Oz (WoZ) testing technique. The research employed an iterative design process, progressing from
This bachelor course, Architecture in the Contemporary, focuses on exploring the spatial and communicative aspects of the 'Naturrum' through surface modeling experiments. Throughout the course, various approaches have been used to engage with the core themes of the subject. Utilizing Rhino and Grasshopper, along with a narrative-driven design process, we have been introduced to the concept
The terrestrial ecosystem stores up to 2400Gt of carbon in the upper 1m of the soil profile. However, this carbon storage is not stable and is vulnerable to loss. Agricultural soils with continuous heavy management drive a release of this soil carbon to the atmosphere. Recently, the implementation of perennial crops has been suggested as a method to facilitate a greater carbon sequestration. Howev
For many years, outdoor localization has been dominated by Global Positioning System (GPS) and other GNSS-based methods. While GPS provides global coverage and usually high accuracy, it has its limitations. GPS has lower accuracy in areas with many obstructions, such as buildings or trees, and is power consuming compared to other localization methods. Therefore, GPS may not be the best localizatio
Family oriented design has long been championed by sprawling suburbs and new town developments. Denser urban places have in most cases not been designed to attract or keep families as inhabitants, instead focusing on other qualities and user-groups. This has consequently led to a family flight from urban settings to monofunctional family oriented suburbs, in many chases exhilarating car-depencany
The subject of energy storage is of increasingly more research interest with a larger share of unpredictable and cheap renewable energy entering the grid. Behind only batteries and pumped hydro in technological maturity, compressed air energy storage stands as a possibility in balancing the grid of the future, with its main benefits being highly efficient utilisation of fuel energy and high flexib
I södra Sverige kan du hitta byn Immeln, som ligger vid södra änden av sjön Immeln. Det är en liten by med cirka 300 invånare. Antalet invånare ökar dramatiskt under sommarmånaderna på grund av den vackra naturen och utomhusaktiviteterna som miljön erbjuder. Detta examensarbete utforskar en industribyggnad och dess tomt som tar upp en stor del av den östra strandkanten av denna by. Genom att utfor
This study investigates whether a pulley system enrichment can improve the hunting behaviors of European wildcats (Felis silvestris silvestris) in captivity. It was carried out in support of the conservation efforts to reintroduce and preserve the endangered Scottish wildcat population. The research was conducted on four European wildcats at Nordens Ark zoo in Sweden. The enrichment device was des
Det finns få behandlingar som leder till betydande symptomlindring för patienter som lider av Somatic Symptom Disorder (SSD), men den internetbaserade psykodynamiska terapiformen Emotional Awareness and Expression Therapy (I-EAET), har visat lovande resultat. Dock finns det inte mycket kunskap om patienters erfarenheter av internetbaserade behandlingar på lång sikt. I denna studie intervjuades tolFew treatments lead to significant symptom reduction for patients diagnosed with Somatic Symptom Disorder (SSD), but the internet-based psychodynamic Emotional Awareness and Expression Therapy (I-EAET) has shown promising results. However, little is known about the patients’ long-term experiences of internet-based treatments. In this study, twelve participants who had undergone I-EAET were intervi
The thesis investigates how a brownfield development, a harbour, can be developed, how urban agriculture, both commercial food production and recreational cultivation, can be integrated into the design and how it should be designed to be both effective and enjoyable and inviting for visitors. A design proposal has been produced that shows such a development. The design proposal is supplemented wit
The post-pandemic rise of non-fungible tokens (NFTs) within the music industry has presented a disruptive innovation that has the potential to reshape traditional business models, offering artists new revenue streams and direct-to-fan engagement opportunities. As music NFTs grow in prominence, they challenge the entrenched systems of royalties and intermediaries, prompting questions about their lo
This thesis starts with an interest to explore how I, as an urban designer, can contribute to make the city centre of my hometown more enjoyable for its citizens and visitors. Growing up in Västerås, the city centre was a place of retail. You walked in the large-scale public realm, looking out for cars when crossing the streets, and visiting the large indoor malls. How can the city centre be impro
Följande studie är en fallstudie om implementering av AI för att driftoptimera styrsystem i kommersiella fastigheter, med fokus på fastighetsägares perspektiv. Studien har genomförts för att uppfylla två huvudsakliga syften. Del ett är att undersöka hur AI kan bidra till minskad energiförbrukning och förbättrad drift i kommersiella byggnader, och vilka incitament som finns för att implementera denThis study is a case study on the implementation of AI for optimizing building management systems in commercial real estate, with a focus on the perspective of property owners. The study addresses two main objectives. The first is to explore how AI can reduce energy consumption and improve building operations, as well as the incentives for adopting such technology. The second is to analyze the org
In this master thesis, the most economically viable option for investing in a new unit in an existing district heating system to fulfil an intermediate load demand of district heating was studied. The investment feasibility of retrofitting a new CHP plan with carbon capture and storage and carbon capture utilization was also investigated. A simulation environment was built in the software Energy O
