Phantoms mimicking the specific mechanical and acoustic properties of human tissues are essential in the development and evaluation of novel ultrasound methods. In this work, various ultrasound phantoms are proposed to be used in the development of ultrasound methods to investigate the arterial walls longitudinal movements influence on the vasa vasorum circulation. The longitudinal movement of art
Korea is characterized by the state's low responsibility for welfare provision and low political trust, while Sweden exemplifies a welfare state with universal welfare provision and high political trust. These characteristics in Sweden arouse interest in the question of whether political trust is causally linked to welfare attitudes and what factors influence political trust. Thus, the present

Purpose The purpose of this paper is to assess whether the overreaction found in ”Does the Stock Market Overreact?” by DeBondt and Thaler still persists today, and by equivalence test if a trading strategy based upon these assumptions would generate abnormal returns. Method The research has been carried out by studies of the stocks that for a prior period of one year has over or underperformed the
Today, drug assisted treatment of Methadone and Subutex is well established in Swedish society. However, it has since the late 1960´s been differing perceptions of both the pros and cons on drug assisted therapy. The purpose and aim of this study was to explore and describe what kind of ethical attitudes social workers and representatives of the Swedish Drug Users Union (SDUU) usually have around
Teachers’ experiences of school leadership behaviour and the social contexts in which these have taken place interest me. I aim to identify and understand what Swedish secondary school language teachers’ reflections are on what they require in terms of leadership from their principals in different contexts in order to gain personal job satisfaction. The objective is that this research can then fun
This Master’s thesis is set to study why art historical museums exhibit their permanent collections in a different way than what is generally more common in natural history and cultural history museums. Whereas art history museums tend to keep their rooms free from voices, natural and cultural history museums tend to (and have for a long while) build up more scenes. I also study how these ways of
The laminate flooring company Pergo (Europe) AB has during the last years identified an increasing market demand for customized flooring solutions. In the autumn of 2004 Pergo had no standardized product offer and the existing administrative process was not suited to produce and deliver customized products. Experiments concerning a new décor production technique with extensive potential based on d
Med röntgenstrålning går det i dagsläget att avbilda kroppens inre anatomi i antingen två eller tre dimensioner. Vid en vanlig slätröntgenundersökning (2D) tas en så kallad projektionsbild från en eller två vinklar, framifrån/bakifrån och från sidan. Detta genererar en tvådimensionell bild där alla (anatomiska) strukturer mellan röntgenröret och filmen överlagras, d.v.s. de går inte att separera fDuring the last century several attempts have been made to overcome the fundamental problem of X-ray imaging, i.e. that anatomical information existing in 3-dimensions has to be represented on a 2-dimensional radiograph. In this thesis, digital tomosynthesis, a rened version of conventional tomography, has been investigated. Digital tomosynthesisenables retrospective reconstruction of an arbitrary

A booster cushion is a cushion used for children age 4-12 years and the purpose of the cushion is to relocate the child into an elevated seat position. A market analy
Fuktdokumentationen för många moderna byggskivor är i nuläget bristfällig, vilket skapar svårigheter i projekteringen. Ett av problemen är skivor som utsatts för stora variationer av relativ fuktighet i dess omgivning. Fuktbetingade rörelser kan leda till problem, då materialet sväller och krymper i takt med att fuktinnehållet ändras. Sprickor i ytmaterialet och välvning i skivan, är exempel på nåMoisture documentation for many modern building boards are currently inadequate, which creates difficulties in planning constructions. One of the problems is when the board is being exposed to large variations of the relative humidity of its surroundings. Moisture movements could lead to problems if the material swells and shrinks as the moisture content changes. Cracks in the surface material and
This masters thesis presents a development of a software to analyse and evaluate a rotary mechatronic demonstration rig. Most of the hardware existed and the task was to develop software in Excel and PLC Ladder to detect dierences between the different setups in a mechatronic system. The software is supposed to be used for educational purposes on Tetra Pak and should thereby be easy to use and giv

Trots att lagstiftningen kring att avskilja en utlänning från andra som hålls i förvar har funnits en längre tid har detta varit ett område som är föga behandlat inom olika rättskällor. Detta framstod för mig som något konfunderande och syftet med denna uppsats var därför att undersöka hur rättsläget kring beslut enligt 11 kap. 7§ utlänningslagen ser ut. Uppsatsen hade även som syfte att undersökaEven though the legislation around separating a foreigner from others who are held in custody has existed for a long time, this has been an area that is little treated in various legal sources. This appeared to me to be somewhat confusing, and the purpose of this essay was therefore to examine how the legal situation regarding decisions according to 11 kap. 7§ utlänningslagen. looks like. The essa
The purpose of this work was to use spatial-temporal analysis for the prevention and mitigation of disease spread. A prototype application was specifically designed to detect territories with a high incidence of cases and a second was used to validate the results. The first algorithm tried to find clustered cases territories and compare them to the smooth average of the previous two years of data

Measurements of heart rate without contact can be of much importance when the possibilities of skin contact for different reasons are limited, or for monitoring at distance over time. This is an emerging area in our time, and the idea to construct a working system to demonstrate the technique was therefore born. The work has been performed at the Department of Biomedical Engineering at LTH. The m
