This thesis proposes a machine-learning-supported pipeline which, put together, provides an estimate of roof surface area for solar panel installation. This pipeline is comprised of roof segmentation based on images and digital surface models and provides subsequent identification of key measurements such as roof length, roof width and roof angle. Obstacles belonging to a roof are also identified
På Lunds Tekniska Högskola studenter som studerar på programmet Civilingenjör inom Kemiteknik en obligatorisk kurs Energiteknik KETF30. Kursen har ett laborationsmoment om värmeväxling som behöver förnyas. Målet med kandidatarbetet är att få fram en laborationsbeskrivning med fokus på värmeväxlarens beteende beroende på olika parametrar och jämföra de två metoder som kan användas för att beskriva At Lund University, students in the program Chemical engineering have a compulsory course Heat Engineering (Energiteknik KETF30). The course has a laboratory practical concerning heat exchanger that needs to be renewed. The goal of this bachelor thesis was to write a description for the practical, focusing on the heat exchanger’s behavior considering different parameters and comparing the who comm
Denna studie ämnar till att undersöka professionaliseringens och den ökade kon-kurrensens påverkan på humanitära organisationer samt hur förändringen påverkar deras kommunikation gentemot medlemmarna och bidragsgivarna. För att konkre-tisera det valda ämnet är denna studie en fallstudie med Rädda Barnen som fall. Studien och analysen är av en kvalitativ typ och vårt empiriska material består av inThe aim of this paper is to examine how the professionalization and the increased competition affect humanitarian organizations, as well as how the changes affect the communication with their members and contributors. We are carrying out a case study of the Save the Children organization in order to concretize the chosen subject. The study and analysis is of a qualitative type and our empirical ma
In order to understand how the Pleistocene glacial cycles have influenced the diversification in the Reed Bunting (Emberiza schoeniclus) subspecies complex, we conducted a multilocus phylogeographic study. We analysed DNA sequences from 32 breeding populations, covering the species’ Palearctic distribution, and used population genetics, phylogenetic and coalescent methods to uncover genetic struct
In this study the three-factor model of Fama and French (1992; 1993) is evaluated on portfolios of Swedish stocks. Both a cross-section and time series approach are used to evaluate the model. The results show that beta, size, and book-to-market are significant variables in explaining excess returns of Swedish stock portfolios. The three-factor model can explain variations in stock returns on the
Astrocytes support normal brain function, but may also contribute to neurodegeneration when they become reactive under pathological conditions such as stroke. However, the molecular underpinnings of this context‐dependent interplay between beneficial and detrimental properties in reactive astrogliosis have remained incompletely understood. Therefore, using the RiboTag technique, we immunopurified
Background: Ketogenic diet in children with epilepsy has a considerable impact on daily life and is usually adopted for at least 3 months. Our aim was to evaluate whether the introduction of an all-liquid ketogenic diet in an outpatient setting is feasible, and if an earlier assessment of its efficacy can be achieved.Methods: The authors conducted a prospective, observational study in a consecutiv
Increased oxidative stress is implicated in the pathogenesis of Alzheimer's disease (AD). A large body of evidence suggests that mitochondrial dysfunction and increased reactive oxygen species occur prior to amyloid-β (Aβ) deposition. Coenzyme Q10 (CoQ10), a component of the mitochondrial electron transport chain, is well characterized as a neuroprotective antioxidant in animal models and human tr
Background: Today, patient self-determination has become an issue in many western countries due to the widespread availability and use of technology, which makes it possible to prolong life often in spite of severe disability and poor quality of life. Many people fear an overzealous use of modern life-saying procedures which merely serve to prolong the dying process. As a first step towards autono
In this work, the new ANO-R basis set for all elements of the first six periods is introduced. The ANO-R basis set is an all-electron basis set that was constructed including scalar-relativistic effects of the exact-two component (X2C) Hamiltonian and modeling the atomic nucleus by a Gaussian charge distribution, which makes the basis set suitable for calculations of both light and heavy elements.
Most migrating birds need to stopover in between flights in order to refuel. Lately, additional purposes of stopover have been suggested, including physiological recovery from metabolically demanding migratory flight. One apparently unavoidable, but harmful physiological effect of migratory flight is increased oxidative damage to lipids and proteins. We here, for the first time, tested whether mig
BACKGROUND: The aim of this study was to investigate the effects of a web-based treatment program with therapist guidance for adults and adolescents with regular cannabis use from the general population. METHODS: A double blinded randomized controlled trial with a parallel group design was conducted (intervention group n = 151, wait-list control group n = 152). Follow-up 12 weeks from treatment co
Stable HCCI combustion requires a proper level of fuel reactivity. This study shows that adding ethanol as a renewable fraction to low octane gasoline decreases the reactivity of the gasoline, while adding 2-ethyl hexyl nitrate (2-EHN) can enhance the reactivity of the blend and counter the effect of ethanol.The experimental apparatus consisted of a modified CFR engine for HCCI combustion equipped
The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). The model reproduced several experimentally measur
