In this thesis a system is developed for robust time difference estimation for multiple microphones in reverberant environments, without any knowledge of the 3D positions of the microphones or the room. RANSAC is used to find line segments in sets of frames containing a number of the largest GCC-PHAT peaks. Focus is on real experiments with one moving sound source continuously playing music. The e
Nanowires have shown great promise in the research field, however, it seems quite a challenge to get them incorporated into the silicon industry and entering the commercial field. One step towards this is to substitute the gold which is used for the catalyst particle for a different material, compatible with the silicon industry. In this project, the possibility of using in-situ nucleation inside
The aim of this study has been to investigate the technical, economical and psychological barriers for the market introduction of battery electric vehicles (BEV) in Sweden. The current situation as well as future possibilities for battery electric vehicles in Sweden has also been central to this study. The study is of a qualitative nature, and is largely based on interviews with experts from the b
Den svenska och internationella spelbranschen har växt under de senaste åren. En större och viktigare spelbransch är också behov av immaterialrättsligt skydd och spel skyddas först och främst genom upphovsrätten. Syftet med den här uppsatsen är att utreda hur skyddet för videospel är utformat i den svenska nationella upphovsrätten. Syftet är också att analysera det nuvarande skyddet och ta ställniThe Swedish and international video game industry have grown the last few years. An expanding video game industry relies on protection of intellectual property and copyright. The purpose of this paper is to examine how the Swedish national copyright of video games is formed. The purpose of this paper is also to analyse if the Swedish national copyright of video games is effective and satisfying an
Forskning har visat att sexuell hälsa är ett tabu-belagt ämne som saknar prioritering inom sjukvården. Sjuksköterskor är ovilliga att tala om ämnet med patienter då de saknar kunskap om ämnet och dess betydelse. Sjuksköterskor har påtalat behovet av strategier för att bryta barriärer och främja deras förmåga att samtala om sexuell hälsa. Denna studie syftar till att belysa de strategier som finns
A large portion of upper-limb prosthesis users are known to defer the use of electronic prostheses due to their high cost, considerable weight and lack of durability. Within this thesis, an approach to simple, low-cost pressure feedback systems is made. Using commercially available pressure sensors and rudimentary materials such as PDMS and polycarbonate plastic, a working prototype for pressure-s
X-rays have been used for imaging for over 100 years due to their unique interaction properties with matter that allow them to penetrate samples and reveal detailed structural information on the atomic scale. NanoMAX is one of the first beamlines to be developed at the new Swedish synchrotron radiation source MAX IV. It will use high brilliance, coherent X-radiation to utilize these properties ful
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
The aim of this study is to examine how the two nature reserves Fågelsångsdalen and Linnebjer are being maintained. Fågelsångsdalen has 16 different management areas whereas Linnebjer has 12. My observations for each of these areas took place out in the field with the help of each management plan and a map of the area. The current status of the different management areas is compared to the managem
There are a number of reasons to form a nature reserve - to preserve and promote biodiversity and to assure areas for outdoor life are two of them. To be able to maintain these values, it is important that an adequate management plan is established for the area in question. I have examined two nature reserves in the county of Lund, Sweden – Fågelsångsdalen and Linnebjer. Both of these reserves con
A climatisation controller for a car with multiple objectives is developed, implemented and tested in simulations. The design focuses on electric cars and their specific characteristics. In this context the goal has been to fulfil common comfort and safety standards while having a low energy consumption. The main idea of the control in order to achieve this is to use a simplified model predictive
The purpose of this Diploma thesis is to develop and implement an interactive simulator for a surgical robot in a Telepresence application. The focus is on an incision procedure of a scalpel during an operation. The geometric deformation of the simulation is based on a Finite Element Method (FEM) model which has to cope with discontinuity due to the incision through the body. The FEM modelling can
In many applications involving mobile devices it is essential to track their position. Moreover, it is usually desired, to perform this localization in a distributed fashion without using a central processing unit. In this case, only distance measurements to reference nodes which are in range can be utilized. It is proposed in this thesis to also use distance measurements to other moving objects,
The objective with the master thesis project is to develop an Electronic Batch Record (EBR) solution for the AstraZeneca TPS division and map it to the ISA 95 model for Manufacturing Execution System s (MES). The EBR solution in addition to current and new manufacturing systems will form an AstraZeneca TPS model for MES, which can be used for further evaluation and system development guidance. The
The US Department of Defense wants one third of ground military forces to be automated by 2015. By using self-driving military vehicles, American troops can be kept out of harm's way in the battlefield.1 To speed up the development, the US Department of Defense decided to arrange a desert race for autonomous vehicles, DARPA Grand Challenge. Team Caltech is entering the Challenge with the vehic
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

This study explores possible gender-specific inclinations, specifically inclinations for cooperation, fairness, discrimination, risk taking and sex stereotyping, all potentially fundamental to negotiation outcomes. The aim is that the findings may provide insight in observed gender inequality in organizational life. Participants in the study were engaged in matrix games with a Prisoners’ Dilemma-l
Trots ett stort intresse för att utnyttja biogas på gårdsnivå finns det idag endast ett fåtal biogasanläggningar etablerade inom det svenska lantbruket. Syftet med denna studie är därför att ur ett ekonomiskt och tekniskt perspektiv utvärdera olikatyper av biogasbaserade kraftvärmesystem på gårdsnivå. De olika tekniker som utvärderas är gasmotorer, gasturbiner och stirlingmotorer.Resultatet från s
