The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

The aim of this study is to examine how the adult students in the Adult Education Initiative called Kunskapslyftet, experience their use of the Main Public Library in Linköping and how the librarians experience the change in their working situation after Adult Education Initiative has started in July 1997. Methods used in the survey are interviews with librarians and students in the Adult Education Initiative. I have also distributed questionnaires to some of the adult students and studied literature that describe students use of libraries. The result shows that the students generally are satisfied with the service they get from the librarians at the Main Public Library. It also shows that what the students mostly asked for, are help to search information about a subject and to find literature in the library.

The Angola black-and-white colobus (Colobus angolensis palliatus) is a subspecies of Colobus angolensis inhabiting fragmented forests in coastal Kenya and Tanzania. C. angolensis is regarded as Least Concern in the red list of IUCN because its populations are abundant. However, the populations of C. a.

Written declarations in the European Parliament have not been given muchattention in the field of political science. The scope of this Master's thesis is toexamine whether symbolic politics are present in written declarations and howthis may show. In this study, the aspects of symbolic politics of writtendeclarations of the sixth parliamentary term are examined using a taxonomy foridentifying symbolic politics developed by Peter Santesson-Wilson. Thetaxonomy is applied on 15 written declarations, all adopted by the EuropeanParliament, dealing with a variety of EU-related issues, ranging from July 2004 toJuly 2008.The main findings of the study show that symbolic politics is a presentphenomenon in nearly all written declarations (13 out of 15 cases) subject to thisstudy.In the final chapter of this study inter alia symbolic politics as a deliberateaction is discussed in the view of written declarations. Irrespective of this, onecould say that symbolic politics are institutionalised in the European Parliament,at least when it comes to written declarations..

Den traditionella förväntade nyttoteorin har kritiserats för att inte vara realistisk i sina förutsägelser om hur beslut tas vid risk. Eftersom de flesta situationer innefattar någon form av risk är det viktigt att utreda ifall man bör söka efter en alternativ teori. I denna uppsats undersöks hur väl nyttoteorin och en konkurrent till denna, prospektteorin, kan förklara riskbeteendet hos Black Jack-spelare. Detta görs genom en studie av fem individers spelbeteende på en krog i centrala Jönköping. Materialet analyseras både grafiskt och statistiskt genom att undersöka om individernas beteende förändras beroende på utfallet dels i de fem senaste händerna och dels under hela spelomgången.

The object with this thesis is to evaluate which of the catch crops oil radish and white mustard in combination with establishment method, give the most effective nitrogen uptake. The main purpose of the catch crops is to reduce leakage of nitrogen. They are sown after the main crop and killed before the next crop. In Sweden the farmers gets subsidies to establish catch crops. The thesis is limited to the trail L3-9010 sited at HS- Malmöhus, Borgeby Gård, 237 91 Bjärred, Sweden, 2007. Only treatments with oil radish, white mustard and the reference treatments were studied.

The purpose with this essay is to study if the exhibition, Maria-Drömmen om kvinnan has a gender perspective and if it contributes to the history of art. The study shows what kind of women the exhibition illustrates and what kind of perspective it has. By telling about the black Madonna I also show that there is another representation of the middle age women in the Roman Catholic Church at this time that the exhibition not have included. The study is also going to illustrate the difference between a genderperspektiv in art and a women?s perspective.

Den höga turbulensen på många av världens börser de senaste åren har ökat efterfrågan på kapitalsäkrade placeringar som ger möjlighet till hög avkastning men innebär en begränsad förlustrisk. En aktieindexobligation sägs vara kapitalsäkrad då den är konstruerad med hjälp av en köpoption och en nollkupongobligation. Mitt syfte med denna uppsats är reda ut begreppet strukturerad produkt av typ aktieindexobligation och med hjälp av Black & Scholes modell försöka prissätta optionen. Detta genom att estimera den implicita volatiliteten på optionen vid olika typer av aktieindexobligationer och jämföra med den historiska volatiliteten. Då den implicita volatilitet är avsevärt högre än den historiska volatiliteten kan slutsatsen dras att emittenter inkluderar ?dolda? marginaler i produkterna i syfte att tjäna mer pengar..

Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and present a relevant solution. This study was conducted in a block experiment with ten blocks planted in 1987 by SCA in North Sweden. The objective of the block experiment was to study if Black spruce is an appropriate alternative to Lodgepole pine, Norway spruce and Scotch pine on different site classes.

Optioner är värdepapper som ger innehavaren rätten, men inte skyldigheten, att sälja eller att köpa den underliggande tillgången inom en given tidsram och till ett givet pris. Vanligen särskiljs det mellan aktieoptioner och indexoptioner. Fokus i uppsatsen ligger på OMXS30 indexoptioner från år 2006. Syftet med uppsatsen är att undersöka om den implicita volatiliteten enligt Black-Scholes formeln bättre predikterar den framtida faktiska volatiliteten än den historiska volatiliteten. I tidigare studier, bland annat i en sammanfattande studie av Figlewski (1997), har resultaten varit tvetydiga.

Optionshandeln har ökat markant på senare år och detta beror på att investerare vill sprida sina risker. Är optionerna korrekt prissatta eller kan det finnas arbitragemöjligheter? De flesta av investerarna använder sig idag av Black & Scholes formel då de prissätter optioner. I Black & Scholes formel är volatiliteten för aktien okänd och måste uppskattas. I denna uppsats vill jag undersöka om likviditeten har någon effekt vid uppskattning av volatiliteten.

I uppsatsen jämförs William Paleys Natural Theology : or, evidence of the Existence and Attributes of the Deity, collected from the appearances of nature från 1802 med Michale J. Behes Darwin's black box : The biochemical challenge to evolution från 1996. Jämförelsen kontextualiseras med en skiss över evolutionsteorimotståndets historia under den mellanliggande perioden, som tillsammans med själva den vetenskapliga utvecklingen, antas förklara de skillnader i tilltal och val av argument som föreligger mellan de två verken. I fråga om grundläggande budskap, idéstruktur, syfte och religiositet befinns de två verken ligga varandra betydligt  närmare än vad som initialt kan tyckas vara fallet..

The purpose of this essay is to study the film culture in South Africa in a national cinema-context, focusing on the relationship between anti-apartheid film from 1974-1994 and the film in South Africa today. By pitching the South Africa-specific works of Lucia Saks and Jacqueline Maingard against the over-arching debate on national cinema as formulated by, amongst others, Stephen Crofts and Andrew Higson, this study aims to find whether or not a specific South African national cinema have existed, and exists today, or not. The study finds that an underground culture of documentaries and short films made by and for the black population has been in place since the apartheid, and the distribution method on video and television is still being used to reach the black population today. By re-examining the concepts of both the national, and of national cinema to also include film on video and television, the study shows that South Africa has indeed a film culture that can be called a national cinema..

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

A common problem in forestry is plant death caused by frost. The risk of frost is highest on wind protected, flat or low-lying areas in the terrain. Here you often have regeneration problems with Norwegian spruce which is especially sensitive to spring frost. Swedish tree experiments have shown that the black spruce can be a suitable alternative on these areas, for example on moisture frost prone areas. The species originates from North America and its pioneer tree characteristics make it more frost hardy than Norwegian spruce.
