Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. The theme of this thesis is to use invariants to solve these
We introduce solution dependent finite difference stencils whose coefficients adapt to the current numerical solution by minimizing the truncation error in the least squares sense. The resulting scheme has the resolution capacity of dispersion relation preserving difference stencils in under-resolved domains, together with the high order convergence rate of conventional central difference methods
The clinical outcomes of primary immunodeficiencies (PIDs) are greatly improved by accurate diagnosis early in life. However, it is not common to consider PIDs before the manifestation of severe clinical symptoms. Including PIDs in the nation-wide newborn screening programs will potentially improve survival and provide better disease management and preventive care in PID patients. This calls for t
This thesis consists of three self-contained papers that all relate to the understanding of equality. The first chapter investigates the effects of preschool attendance on children in Kenya and Tanzania. We use a within-household estimator and data from nationally representative surveys of school-age children's literacy and numeracy skills, which include retrospective information on preschool att
This thesis, written at Scania CV AB in Södertälje, Sweden, during the spring of 2015, treats the subject of Solid State Fuses and the possibility to use these in heavy vehicles. A Solid State Fuse is a device containing only solid state components, implementing a function to protect wiring harness and connectors from damage caused by electrical faults. The device should contain circuit breakers a
The six participants, two in Sweden and four in Denmark, interviewed for this thesis are all organizational outsiders: they consult organizations on how to create diverse workplaces. The empirical, qualitative material is analyzed within an interdisciplinary framework consisting of feminist, queer, anti-racist, affect and critical diversity theories. The focus of the thesis concerns resistance fro
The majority of the current 3GPP and M2M networks use or will use IPv6 for accessing the internet. These IPv6 networks use Neighbor Discovery as defined in RFC 4861 to identify their neighbors on the link and see if they are active. The increase in the complexity of wireless networks and introduction of battery operated devices sets forth notable challenges to certain assumptions in the RFC 4861.
HVAC systems are widely used to provide a good indoor air quality in buildings. Buildings stand for a substantial part of the total energy consumption in developed countries, and with an increased focus on cost reductions and energy savings, it is necessary to use intelligent and energy-efficient controllers. Accurate models describing the dynamics of the building system is a good basis for intel
Syftet med undersökningen är att rapportera hur rytmikpedagogik och rörelsebaserad musikundervisning kan bidra till ömsesidig integration bland elever i en multikulturell svensk skola. Jag har genomfört en studie där jag kombinerar en internetbaserad enkät med en fokusgruppsintervju. Femtio musikpedagoger över hela Sverige svarade på enkäten, de flesta vilka arbetar med El Sistema. El Sistema erbjThe purpose of this study is to investigate how eurhythmics and body-based music education could contribute to mutual integration of students in a multicultural Swedish school. I have conducted a study, combining an Internet-based survey with a focus group interview. Fifty music teachers throughout Sweden answered the survey, most of who work at El Sistema. El Sistema offers optional music educati
Detta examensarbete undersöker styvhetsegenskaperna för tre armeringsmaterial: ferrocement, glasfiber- och kolfibertextilarmering, tillämpade för skalkonstruktioner. En av de strategier som användes för undersökningen var ett mekaniskt försök med kompositarmerade betongbalkar. Det mekaniska försöket skulle sedan verifieras med numeriska och analytiska modeller. Jämförelser mellan de mekaniska och The purpose of this master’s thesis is to investigate the stiffness properties of three reinforcement materials for concrete shell structures: ferrocement, glass-fibre textile and carbon-fibre textile. Three types of strategies were used to analyse the properties of the materials, an analytical model, experimental beam prototypes and a numerical analysis. Immediate comparison of the mechanical exp
Abstract I would like to thank my mentor Richard Murray at the Control and Dynamical Systems Department of California Institute of Technology (Caltech) for giving me the opportunity of conducting my master's thesis at Caltech and for his support during the project. I would also like to thank my other mentor Anders Rantzer at the Department of Automatic Control of Lund Institute of Technology u
Reco Port AB is a company that builds folding garage doors and is a part of the ASSA ABLOY group. Reco uses Styrofoam as insulation in their doors and their current solution of cutting the Styrofoam is using a plunge saw and a custom built table to hold the Styrofoam in place. The solution is not ergonomic and spreads a lot of debris of Styrofoam around the workstation. Due to this it was requeste
Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a
The existing Power Supply Unit (PSU) at Axis Communication contains a fully discrete solution that lacks flexibility for future updates. This research aims to address critical challenges by exploring methods to enhance speed, reduce PCB area, and introduce flexibility to the existing hardware solution. The approach involves replacing hardware functionalities within the control unit with software-c
The aim of this bachelor degree project is to design a modular luminaire with a longer lifespan, in order to reduce consumption. The project aims to explore how design can contribute to sustainable development by creating a durable and adaptable lighting solution. The luminaire is versatile and can either be hung from the ceiling, mounted on the wall, or placed on a table. It can be expanded
Modern-day opportunities allow musicians to divert from normalised, widespread perceptions of their artistic needs and pursue diverse career paths. This thesis uses autoethnographic methods to explore a classical pianist's navigation between contrasting fields, such as international relations, higher education management, and music and performance. Artistic citizenship and discourse theory hav
The efficiency of combustion engines is crucial for their future development, prompting researchers to explore various factors to enhance performance. Among these factors, exhaust gases hold significant potential. Typically, exhaust gases carry about 30-40% of the engine's energy, which often remains underutilized. Although technologies like turbochargers have made progress in recovering some
