Undervattensvågbrytare - En modellstudie
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Djurskyddsinspektörer : - Behovet av kunskap om exotiska djur
Psittacines and reptiles are exotic animals that are difficult to care for and it requires extra knowledge to make a correct assessment of their wellbeing. An animal welfare inspector, with an education in general animal welfare, may not have a deep enough knowledge of exotic animals to do a proper assessment of the animal?s general condition and its environment. In this paper it was therefore examined if animal welfare inspectors have enough knowledge to do a satisfying inspection of establishments working with selling of exotic animals. A literature study was used to examine difficulties with each species.

Ung, Snygg och Hälsosam - Social kroppsanspänning och tilltro till handlingskontroll bland flickor och pojkar i skolår 7 och 9
The aim for this study was to describe Social Physique Anxiety and Self-Efficacy in the school year of 7 and 9. To that the aim for this study was to describe if there was differences between girls and boys, but also between the school years, when it comes to the estimation of Social Physique Anxiety and Self-Efficacy. The method for this report was of statistic design, with a deductive methodology who was analysed and presented in. The empirical material was collected thru questionnaires where the level of information was of quantitative characteristics. The results from this study showed that girls estimate higher Social Physique Anxiety then the boys, in school year 7 and 9.
Kreditgivares agerande vid sjunkande skogsfastighetspanter
Background: The hurricane in the south of Sweden in January 2005 was the worst storm in Sweden for the last hundred years. The storm named Gudrun has blown down forest that according to estimation is corresponding to one year of cutting down in the entire country.Purpose: The purpose of this thesis is to describe how credit granters act when facing falling forest real estate mortgage and describe if they will make considerations due to the storm in the south of Sweden 2005.Method: With help of a qualitative method, we investigated how the credit granters act when facing falling forest real estate mortgage. Interviews were obtained with three credit granters, SEB, Landshypotek and FöreningsSparbanken in the county of Jönköping and Kronoberg.Conclusion: The conclusion is based upon the empirical study, the analysis and our own reflections and it shows that the credit granters do not change their policy concerning credit granting to forest real estate properties. The policy of the credit granters has proven to be valid even in this extreme situation..

Forensisk längdmätning i bilder
Detta examensarbete undersöker forensisk längdmätning i bild, t ex längduppskattning av människor i bilder rörande brottsmål. Problemen identifieras och några av dagens befintliga längdmätningsmetoder diskuteras.Den metod som bäst uppfyller de i arbetet ställda kraven, d v s snabb handläggning, minimal systeminformation, minimalt arbete på plats och exakthet, har valts ut, anpassats och utvärderats. Metoden bygger på att hitta s k gränspunkter och grundplanets gränslinje i bilden och utifrån en i världen känd referenslängd beräkna den sökta längden. Den bakomliggande teorin presenteras och metoden beskrivs i detalj. Funktioner, algoritmer och ett användargränssnitt har implementerats i beräkningsprogrammet MatLab.
Beslutsfattande vid anbudsgivning hos svenska byggentreprenörer
This thesis examines the tendering process from the point of view of Swedish building contractors. The purpose with the study is to chart the decision process for the contractors during the tendering process. The study is designed as a survey study. This made it possible to reach a wide base of respondents, not letting such factors as geography being an issue. The survey itself was characterised by a very high response rate compared to other similar studies. The result from this study shows that former experience from similar projects, current workload and the clients economic condition are very important factors for both whether or not the contractor will bid for a project as well as the cost estimation and tendering price. Former experience from similar projects is also an important factor for the determination of the indirect costs.
Mixtekniker
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.
Hur ser lavars fördelning ut runt stammen på ek, och påverkas den av trädets storlek och dess närmiljö?
The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.
En simuleringsmiljö för distribuerad navigering
This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.
Synen på manligt och kvinnligt ledarskap : Ur ett manligt och kvinnligt perspektiv
The study is quantitative and is about working men and women?s view of male and female leadership. The intention of the study is to see if the men and women have a different perception of male and female leadership and also if they have different personality types. The method used was a survey where the sample is 80 participants, 31 men and 49 women from four different companies. Previous research shows that the perception of male and female leadership can be different, and that the reason can be prejudices and beliefs.
