Due to higher demands on the electrical systems in the aviation industry, the generation and distribution of electrical power, in aircrafts, needs to be researched and developed further. Key requirements include increased power capacity to meet future demands, a transition from AC to DC supply and an increased voltage level. For power generation, a generator is coupled to the jet turbine which mus
Today, buildings account for approximately 30% of worldwide energy use, with HVAC (Heating, Ventilation, and Air Conditioning) systems representing nearly 40% of that total. Improving the energy efficiency of HVAC systems is therefore essential for reducing operational costs and mitigating environmental impact. Because HVAC systems operate continuously and under strict operational constraints, acc
The widespread adoption of drones has presented new requirements for reliable localization and tracking systems. For this reason acoustic sensing has become an area of growing interest for a passive and cost-effective solution. However, process- ing large amounts of microphone data in real time presents significant hardware challenges. This thesis studies two different types of signal channelizati
Brine disposal remains one of the most significant environmental challenges associated with desalination, driving the need for sustainable technologies such zero liquid discharge (ZLD) systems. Among emerging ZLD techniques, membrane distillation crystallization (MDCr) offers a promising approach by integrating water recovery with salt crystallization. In MDCr, a hydrophobic membrane separates wat
Deterministic Galerkin finite element methods deliver high-fidelity solutions of partial differential equations (PDEs) but do not fully capture the inevitable uncertainty in material parameters, boundary conditions and external forcing. This thesis presents a unified framework that spans classical Galerkin discretisation and its stochastic counterpart, enabling uncertainty simulation of diffusion-
Stora mängder koldioxidutsläpp från stora infrastrukturprojekt är en av de mest angelägna utmaningarna inom dagens bygg- och anläggningsbransch, där klimatbelastande material ofta används i stora mängder. Markstabilisering är en beprövad teknik för att förbättra bärigheten hos svaga jordar och erbjuder både tids- och kostnadseffektiva lösningar. Trots dess fördelar är metoden förknippad med betydaLarge-scale carbon dioxide emissions from major infrastructure projects constitute one of the most pressing challenges within the contemporary construction and civil engineering sector, where climate-intensive materials are often used in considerable quantities. Soil stabilization is a proven technique for enhancing the bearing capacity of weak soils and offers both time- and cost-effective soluti
This thesis explores the use of Large Language Models (LLMs) to convert natural language questions into SQL (Structured Query Language) queries within the field of sports analytics, with a focus on a real-world use case for Spiideo, a provider of cloud-based video analysis tools. The study compares different system designs, including single-agent and multi-agent setups, various prompting strategie
Making buildings more sustainable and energy efficient, increases the importance of interoperability of Building Information Modelling (BIM) and Building Energy Modelling (BEM) in the design process. The increasing use of these software calls for finding more efficient ways to work between BIM and BEM. This paper explored different workflow methodologies between BIM and BEM software focused on tim
Det här examensarbetet går ut på att göra en konceptstudie och dimensionering av ett handledsverktyg för den snabba materialhanteringsroboten HKM från Cognibotics. Handledsverktyget skall möjliggöra att robotens funktionalitet utökas och breddas. HKM-robotens unika kombination av räckvidd och hastighet i kombination med ett nytt handledsverktyg ger företaget goda möjligheter att etablera sig inom The purpose of this thesis is to perform a conceptual study and dimensioning of a wrist tool for the high-speed material handling robot HKM by Cognibotics. The wrist tool is intended to enhance and broaden the robot's functionality. The unique combination of reach and speed of the HKM robot, in combination with the new wrist tool, gives the company good prospects to establish itself in the log
This thesis investigates the suitability of reinforcement learning (RL) for solving the optimal execution problem in financial trading. It evaluates the strengths, limitations, and practical considerations of applying RL techniques to this task. Several RL algorithms were implemented and tested, including Double Deep Q-Network (Double DQN) and Proximal Policy Optimization (PPO), both of which achi
Residential sprinkler systems have been mandatory in newly built Swedish care homes for the elderly and group homes for people with disabilities since 2012. The regulation was introduced on the assumption that sprinklers are a cost-effective life-safety measure for a highly vulnerable population. This thesis re-examines that assumption through a three-part study: (i) a review of international stud
Bathymetry, the measurement of underwater terrain, is crucial for understanding lake storage volumes, water resource availability, and ecological conditions. While there are an estimated 117 million lakes worldwide, bathymetric data remains limited for most of them. Traditional methods for measuring bathymetry requires fieldwork which is costly and time-consuming. For this reason, new less fieldwo
Cancer remains a leading cause of death worldwide, with over 200 types characterized by uncontrolled cell growth and spread. Despite advances in understanding its molecular basis, treatment remains challenging. Chemotherapy, a common approach, lacks specificity and often harms healthy cells, leading to severe side effects. To address this, targeted therapies have emerged, aiming to deliver drugs d
Detta examensarbete utvecklar fram en skräddarsydd prototyp av en tillgänglig kommunal webbplats. Det innebär en kommunal webbplats som är anpassningsbar och lätt att navigera, speciellt för användare som tar hjälp av tillgänglighetsverktyg för att utforska webben. För att kunna ta fram denna prototyp, utvecklades först två prototyper som var nära besläktade. Dessa två prototyper jämfördes sedan This thesis project brings forth a tailored working prototype of an accessible municipal website. This means a municipal website that is adjustable and easy to navigate, especially for users in need of accessibility tools to browse the web. To create this prototype, we first created two separate prototypes that closely resembled each other. These two prototypes were then compared to each other and
Tillgång till rent vatten och fungerande avloppssystem är en grundläggande samhällsfunktion som kommunerna ansvarar för att tillhandahålla. Dessa funktioner möjliggörs genom omfattande nätverk av VA-ledningar som ofta placeras i kommunalägd mark. När VA-verksamheten bedrivs genom kommunala bolag eller kommunalförbund uppstår frågor om markupplåtelseersättning till kommunen. Det saknas tydliga riktAccess to clean water and functioning sewage water systems is a fundamental municipal responsibility, often realized through extensive networks of pipes placed in municipally owned land. When water and sewage water services are managed through municipal companies or inter-municipal associations, questions arise regarding compensation to the municipality for the use of municipal land. The lack of c
The persistent Energy Performance Gap (EPG) in buildings poses a major obstacle to achieving predicted energy savings and sustainability targets. This study provides a comprehensive review of EPG root causes and mitigation strategies across the building life cycle, encompassing the design, construction, and operation phases. Technical and soft mitigation measures were synthesized, including smart
This thesis explores 4D reconstruction in sparse fixed-camera settings for virtual reality visualization. Gaussian Splatting provides an efficient representation for static and dynamic scenes, but most existing pipelines rely on dense multi-view capture or sufficient camera motion. This project focuses on a constrained setting with only four fixed cameras observing a dynamic human object, where li
Oligonucleotides are short fragments of RNA or DNA that can act as active pharmaceutical ingredients (API) in medicines used to target a wide range of diseases, with further applications continuously emerging. Solid Phase Oligonucleotide Synthesis (SPOS) remains the dominant platform for oligonucleotide production. However, SPOS is characterized by high reagent consumption and a poor sustainabilit
