Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Lawsonia intracellularis is an important pathogen in the intestine, causing diarrhea and retarded (or poor) growth in pigs. Diagnostics is based on sampling of small amounts of faeces. Several publicated scientific papers mention the use of faecal swabs as sampling material for diagnosis in experiments and in prevalence studies. Therefore the need of an evaluation of this sampling technique is urgent since, to our knowledge, this has not previously been done. Here reported work compare the use of rectal swabs for feacal sampling, with sampling and analysis of 0.1-0.2 gram of faeces. The studie included twelve herds with a case history of earlier or ongoing problems with diarrhoea where Lawsonia intracellularis could be suspected as the causative agent. A total of 120 growing pigs where examined.

Large companies in today?s business environment are to a great extent depending on their credit score by rating institutes like Moody?s and Standard & Poor?s. There is however indications that these big institutes are not always rating companies accurately. This is why this thesis aims at developing a new credit rating model, CRITA-Score, with the objective of determining a company?s financial health more accurately.

The purpose of this study is to show what melancholy and irony in my poems express and what techniques that are used to accomplish these effects. Many theorists, among them Sigmund Freud and Julia Kristeva, characterize melancholy as an experience of loss, and therefore one of my questions is what kind of losses appear in my poetry. In search for an answer I analyze the texts from both a psychoanalytic and a sociological point of view. In the latter perspective I discuss the postmodern society using concepts from contemporary thinkers like Zygmunt Bauman, Fredric Jameson and Jean Baudrillard. Finally, I also examine if melancholy has an influence on the form of the poems.

The interest in tiny wireless applications raises the demand for an integrated reference oscillator with the same performance as the macroscopic quartz crystal reference oscillators. The main challenge of the thesis is to prove that it is possible to build a MEMS based oscillator that approaches the accuracy level of existing quartz crystal oscillators. The MEMS resonator samples which Philips provides are measured and an equivalent electrical model is designed for them. This model is used in the simulations of the Pierce oscillator and the transresistance amplifier oscillator that are evaluated in this thesis. Finally the Pierce oscillator is implemented in the A BCD2 process and manufactured at Philips Semiconductors in Nijmegen, The Netherlands.

In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.

This is a critical discourse analysis of the conformation of the conflict in Goma, Democratic Republic of the Congo, as constructed by Ekot, a news-show on Radio Sweden. The ambition of this bachelor thesis is to examine the production of a Congolese conflict for a Swedish audience and to find out how the construction differences with and without a reporter in the field. To obtain this purpose the narrative is studied as well as the use of voices that define the conflict. The construction of proximity between Swedish audience and the Congolese event and the meaning of sound to stabilize the formation of discourse within foreign news is examined as well. To conform and explain foreign news it must be put in relation to a starting point.

Sweden has a long tradition as a mapmaking nation. Tens of thousands of historical maps,dating from the sixteenth century and onwards are still preserved in archives today, providinga rich resource for studies of city growth and changes in the landscape through time. For morethan ten years an effort has been made by public authorities to transfer this material frompaper onto digital media. Due to modern technology, as for example GeographicalInformation Systems (GIS), researchers have been given improved possibilities to study andanalyze this material. This study uses a qualitative approach, based on both literature studiesas well as map studies.

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

There have been, in some rare cases, difficulties with clamping of inserts with U-holesin their tool holder. According to the complaints, the inserts could not be properlyclamped or could fracture when clamped. A study has shown that variations inclamping behaviour are mainly depending by the position of the screw hole in the toolholder and the centering of the screw hole in the insert.The focus of this project has been the centering of screw hole in insert. It has beenshown that the screw holes are not always enough centered in the insert. Theproblem may occur after a certain step in the production, i.e.

The aim of this report is to investigate how the work handling at the department for arriving goods at EFG in Tranås is working, as well as how it could be improved and made more effective. EFG is a corporation who process and sell office furniture. The company is working with a project concerning delivery precision, the subject is therefore particularly interesting from the perspective of delivery accuracy. The number of orders has increased notably during the fall of 2005 and the spring of 2006. This has led to new demands at the department for arriving goods and the topic is as a result of that important also from this point of view.Interviews and investigations have been conducted at location since no written material earlier has been made in the topic.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

Syftet med uppsatsen är att definiera hur begreppet kvalitet ska tolkas för poker på Internet. Genom att ställa användarnas upplevda kvalitet gentemot branschens definition på kvalitet, ämnar vi att öka förståelsen för vad som betecknar en god kvalitet på en Internettjänst. Vi har använt oss av en kvalitativ ansats bestående av två djupintervjuer och två fokusgruppsintervjuer. Insamlingen av empirisk data och framtagningen av det teoretiska ramverket har varit en iterativ process. Inledningsvis diskuteras hur tjänster och kvalitet kan definieras utifrån några välkända kvalitetsmodeller, bland annat Grönroos (2002).

Booth for operational planning of harvesting and for long term planning, data is today collected manually. Intensive objective field inventories are usually too expensive. To enhance optimisation of timber flow from forest to industry Moore efficient methods for measuring tree stems of standing trees are needed. The performance of terrestrial laser scanners have improved and these could possibly be used within forestry in the future. The objective of this study was to validate how a terrestrial laser scanner could be used to measure stem diameter, and to test how the errors depend on distance from the scanner and tree species. Two plots (one pine and one spruce) were used for this study.

The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality. The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.
