is a requirement: It would be preferred that a wind turbine with a life of 20 years could repay itself for at least 10 years, if that investment wants to feel worthwhile. This is due to investment costs and annual production of the plant. However, the produced electricity, which is defined by suppliers, is not reliable. This is because the estimated annual production is usually given at the averag
The main idea with this thesis is to discuss the situation of the parent and the teacher of a child with attention deficit hyperactivity disorder (ADHD). Previous research on the parents’ and the teachers’ per-spective of the children has helped me to understand the complexity of the disorder. I have analyzed a single case of a child from Poland who came with his parents to Sweden and started educ
This master thesis was carried out at Lund University in collaboration with the European Spallation Source (ESS). It brings up the question of whether it’s possible to find an optimal solution for complex power electronic topologies, using a well formulated global optimization methodology. The commercially available software tool MATLAB was adopted for these studies, including its own toolbox for
When making decisions regarding investments and planning of the distribution network, it is of great help to be able to calculate and analyze the reliability. The main interest is to study how many of the faults occur and the duration of these faults. The software Tekla NIS contains a module for calculation of the reliability of distribution systems, this is also known as reliability based network
The aim of this master thesis is to present new and well proven methods about how to best design an overview display. Since designing is a creative process and there can be many alternative designs that fulfill the same requirements, this master thesis will focus on presenting guidelines and principles that will aid in the design process. How to design an effective interface display will be discus
People spend more and more of their awaken time indoors, resulting in no or little exposure to sunlight during the day. Natural daylight is superior to artificial light concerning our biological and psychological health, and it is one of the most important external signals to the circadian system, the “wake and sleep”-clock. The objective of this thesis was to develop a luminaire which spreads sun
Your everyday milk carton is coated with thin layers of plastic to protect the carton from soaking up its liquid content and thereby ruining the carton. For more aseptic products the carton can also include a thin layer of aluminum together with a plastic film. The purpose of this project is to analyze the creation process for these thin plastic layers using a machine vision system
In the summer of 2014, about one million Iraqis were forced into internal displacement in the Kurdistan Region of Iraq (KR-I) following successful incursions of the Islamic State of Iraq and the Levant into bordering areas. To mobilize assistance and respond to the immense humanitarian needs, the UN assigned the situation its highest level of emergency, L3. This thesis investigates the emergency r
Abstract Author: Yasar Jaber Title: Self-determination in LVM-care - a study about the laws definition and the care providers` interpretation of self-determination. Supervisor: Jan Magnusson The purpose of this study is to find out how self-determination is defined in LVM-law and how it is interpreted by the care providers in LVM-health and rehabilitation clinic. The used method is qualitative met
Sammanfattning Syftet med den här studien var att undersöka hur vårdpersonalen på äldreboenden upplever arbetet med äldre med annan kulturell och/eller språklig bakgrund utifrån kommunikation, förståelse och möjlighet att tillgodose behov. Syftet var även att lyfta fram rådande svårigheter inom omsorgsgivandet till äldre invandrare över 65 år. Metoden som användes var kvalitativa, semistrukturerad
Bakgrund: tidigare studier visar att kvinnor upplever att föräldragrupper inte förbereder dem för amning. Det är viktigt att studera hur kvinnor upplever amningsinformation under graviditeten då detta kan öka amningsfrekvensen. Syfte: Att undersöka kvinnors upplevelse av amningsinformation under graviditeten. Metod: en kvalitativ studie gjordes och elva kvinnor intervjuades. Kvalitativ innehålls
Artland är en reflektion kring relationen mellan människan och andra arter, samt en vision om hur stadslandskapet kan bli artrikare. Mängden vilda djur minskar drastiskt i världen, det är fler och fler arter som väljer staden som alternativt habitat och det finns ett behov av närnatur och sammanhängande gröna rum i den urbana kontexten. Detta ledde för mig fram till frågorna: Hur kan arkitekturArtland is a personal reflection on the relationship between the human being and other species, and a vision for how cities can be richer in species. The amount of wild animals decrease drastically all over the world, more and more species move into the city, there is a need for nature and green infrastructure in the urban setting for many species. This made me ask the questions: How can archite
The bearing principles of the Law of support and Service for people with Certain Functional Impairments (LSS) are to create a freer and more self-determined user, limit government intrusion and paternalism. This whilst the main objectives of the Health Care Law are to uphold good health and care on equal terms for the entire population. This essay investigates whether these two principles might be
This report describes the development of a green design camera concept for Axis Communications AB. The problem description for this thesis stated that the concept should be developed by modifying one of Axis current products to achieve a decrease in environmental impact. Also, the Cost of Goods Sold (COGS) of the camera should not be increased and the concept should be able to fulfill the same mec
In conventional design of pile foundations, all loads are taken by the piles, i.e. the contact pressure between the raft and the soil is neglected. In the last decades geotechnical engineers have started to take this pressure into account in design of pile foundation. Such a foundation, where the raft and the piles interact to transfer the loads to the ground, is in this dissertation called piled
In mining for extraction of metals residues are often produced. A frequently produced residue is tailings, which potentially contains high amount of metals, soluble salts and acids. Therefore, it is often necessary to deposit, the tailings in stable impoundments, namely tailings dams, if not all tailings produced is used as backfill in mines. In the construction of the tailings dam in Garpenberg,
This master’s dissertation has been performed in cooperation with Tyréns and the Dept. of Construction Sciences, LTH. We have investigated if it is possible to increase the total stability for excavations with retaining structures and if each side of an excavation could be treated as a separate 2D-case with additional theories to approximate its 3D-effects. End-surface theories from the Commissio
