Image artefacts in diagnostic ultrasound partly occur due to a number of assumptions made concerning how sound and tissue interact and of the acoustic properties of tissue. Ultrasound artefacts in B-mode imaging and the underlying physics that cause them is a well-documented subject. These artefacts and the causes behind them have been studied with the goal of designing a number of ultrasound phan
To operate effectively in large organizations such as the county council it is required to distribute responsibilities throughout the organization. This distribution is made through a hierarchic system where staff in the lower levels are providing material for the higher levels to make decisions upon. Risk experts, working in the lower levels of the hierarchic system often have more technical kno
This masters thesis presents a new approach to enable complex illuminationand shadowing for transparent objects such as glass or smoke. This is achievedby combining two algorithms which are intended to run in a real-time environment commonly found in modern computer games. The first algorithm is called "Light Linked List", it solves the problem of illuminating transparent objects and was
The thesis engages in a comparative analysis of the involvement of National Human Rights Institutions (NHRIs) in the UN and the African human rights systems. Thus, the thesis seeks to answer the question: What lessons can be drawn from the system of the involvement of NHRIs in the UN Human rights system to that of the African human rights system? Assuming that the UN system is far more developed a
This study examines the integration of climate adaption in risk and vulnerability analyses in Swedish municipalities. The study is based on a selection of municipalities that work actively with environmental questions. The risk and vulnerability analyses of 15 municipalities have been compiled and analyzed. Interviews have been carried out in three of the municipalities. Among the selected municip
Parts of the postmodern consumer research argue that researchers must change their perspective from a modernist to a postmodern point of view when studying consumers and consumption. This postmodern perspective is described by Firat and Venkatesh (1995) through five conditions of postmodern consumption. These conditions describe a fragmented individual who wants to consume on his or hers own premi
This thesis describes the legal system of joint perpetratorship. The prosecution of organized crime raises serious procedural questions. Organized crime is a wide term; it is not possible to state in general terms. In order to understand the involvement in crime over time there is a definition of criminal organizations and gang violence. The gang crime and the organized crime groups overlap and
I Sverige har under ungefär tio års tid grupper av ungdomar och unga vuxna med intresse för japansk populärkultur samlats på så kallade konvent. Dessa kan beskrivas som öppna, sociala evenemang där människor som är intresserade av japansk eller ”nördig” populärkultur kan umgås och roa sig. Uppsatsen är en ansats att förstå konventfenomenet – vilken mening och vilka betydelser har konventen för del
The aim of this master thesis is to analyse the development of existing guidelines for storing of solid biofuels as well as highlighting doubts on how storage and handling of biofuel within CHP industry and paper mass industry. Through interviews and site visits, identify what risk reducing measures that are applied in practice. In an effort to analyse statistics and examine the frequency of the v

Syftet med denna uppsats är att i detalj undersöka metoderna som används vid de högsta instanserna, rörande mänskliga rättigheter, i USA och Europa. Författaren har för avsikt att belysa likheterna och skillnaderna i deras tolkningsmetoder, rörande Artikel 6 i Europeiska konventionen om skydd för mänskliga rättigheter och femte, sjätte och fjortonde tillägget till de förenade staternas konstitutioThe Purpose of this essay is to investigate in detail the methods employed by the highest courts of law, concerning human rights, in both the USA and Europe. The author intends to highlight the similarities and differences in their methods and in regards to Article 6 of the European Convention on Human Rights and the Fifth, Sixth and Fourteenth Amendments to the U.S. Constitution. This will be don
I started with the intentions to design a toy. Many of the values I wanted to emphasize are part of or could be applied to the soap-box cart. A traditional soap-box cart is built by hand from bought or collected (left-over) parts and materials. The creation plays a major part in the soapbox concept and I wanted to preserve this. My challenge was to revive the old soap-box cart and adapt it to the
Both globally and from an individual perspective, water is the most important resource we have on earth. Knowledge of groundwater and groundwater recharge is important from many perspectives, such as environmental, socio-economic and structural engineering. The thesis is written at Lund University in Environmental sciences and aims to highlight groundwater recharge to the crystalline bedrock and g
Does my belief actually matter in the dialogue with a person of another religion or denomination? Two often occurring themes within Gavin D'Costa's and Paul Knitter's explorations within the realm of theology of religions are dialogue and the possibility to learn from someone with whom I do not share beliefs. The essay at hand studies how D'Costa and Knitter relate to different, Ch
The aim of this report is to increase the knowledge about the use of infrared cameras within fire services. A construction made up of several different types of walls and ceilings was built and used in a large scale fire test. The actual temperature was measured with thermocouples and compared to the temperature given by infrared cameras. The heat wave and the infrared images themselves were also
The accurate and reliable detection of opening of doors and windows is vital for home security applications. This master thesis aims to present a way to achieve this using a low-cost and low-power ecompass, containing a MEMS accelerometer and a magnetometer. This has been achieved by attaching such a device to a door and collecting sensor data when opening and closing the door. Said data were then
Arbetsgivare använder sig allt mer av olika övervakningssystem av diverse anledningar. Även då det är en vanlig metod är övervakning ett negativt laddat ord och många är osäkra om den personliga integriteten bevaras. Syftet med denna studie är att undersöka vilka effekter övervakningssystem har. Jag försöker lyfta fram fördelar och eventuellt reducera en del av den negativitet ordet medför. Den em
This study aims to examine the topic of innovation in China. The need for innovative development is of importance for the nation to keep the rapid development. A few evaluations of both Chinas indigenous innovation policy and the opportunities for the citizens to develop innovation has criticized the lack of creativity in human resources and the examination based education system to be harmful for
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
A sustainable approach could be a solution for the tourism industry to reduce its climate impact. The aim of this thesis was to develop a sustainable tourism strategy, in collaboration with Swedish region Halland. The sustainability concept was set against the developed tourism strategy, both on a theoretical and practical level. The strategy was compared to other sustainable tourism strategies a
