The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.

Background: As a result of the financial markets ever ongoing product innovation a new derivative was introduced in the USA in 1997. A derivative that derived it's value, not from the price of an underlying asset, but instead from a climate factor. It's been known for a long time that revenue in certain industries are affected by weather conditions. The suppliers of weather derivatives claim that these weather sensitive businesses can user weather derivatives in order to lessen weather risk. Purpose: To do a critical evaluation of how weather derivatives can be used by companies as a risk management tool.

The Swedish Parliament has decided to increase the share of electricity produced by wind power. The same parliament has decided that the Sami have the right to herd reindeer over 50% of the country's land area. In this literature review the potential impact wind power development and associated infrastructure may have on reindeer husbandry conditions are examined. The unique physiology of the reindeer enables it to live out of grazing in the arctic climate in the north of Sweden. For reindeer husbandry to be long-term productive and sustainable, it is important that there is enough land for grazing. The research available on how reindeer are disturbed by human activities such as roads, mines, hikers, etc., clearly indicates that the reindeer avoids areas close to such disturbance.

This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.

The purpose of this literature study was to describe the seasonal reproduction in sheep and the presence of genetic variation in fertility traits. Methods to induce oestrus are described and the possibilities to change the reproduction season through breeding are discussed. Sheep have a pronounced seasonality in their reproduction. Mating season starts in the fall and the lambs are born during the spring because this is the most beneficial time. The market request for lamb meat has increased and therefore it is desirable with ewes that could get pregnant all year round.

This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.

With a shifting world market and periodically profitability issues, Swedish farmers seekalternative ways to enhance their profitability. One interesting alternative to get a highervalue and enhance products is biodiesel, a way to improve the profitability on a farmscale.The diesel that is produced and sold, already have a mixture of 5% biodiesel, andthere is a possibility to add more biodiesel to it. By developing new engines severalengine-manufacturers now allow a mixture up to 100% biodiesel in their engines. Hencethere is a market for an increased production of biodiesel. The aim of this study were toinvestigate the possibilities and the problems related to farm-scale production ofbiodiesel, and to study the profit margin in the production.

"What's feminine about the Women's library?" This library, Kvinnobiblioteket, is abranchoffice at Björkskatan in the city of Luleå, and the introducing question is thestartingpoint of this essay. To find some possible answers is its object.One way of describing what's feminine about Kvinnobiblioteket is through presenting itsobjective, ambitions and methods of working. That is done mostly in a chapter headlined"Kvinnobiblioteket", and shows how the women's perspective concerns for exarnplepurchase of books and magazines, displaying of books, the opening hours, design etc.Although the focus in the survey is not in the former kind of description, but in the interviewsbeing made during a two week long period of time with ten women at Kvinnobiblioteket(both library user and personnel) at spring 1995. The results of the interviewsthen have been compared with theories from psychological-, feminist-, literature- andlibrary and information sciences, as we11 as to former surveys and essays.The material together leads to some keywords that seem to be important when trying tofind out what's female about the women's library.

This thesis investigates in which way principles and theories of usability is revelant when evaluating interactive systems for children aged 10-12. It also investigates whether there are specific factors that you should keep in mind while developing interactive products for the targeted group.The results of the qualitative study shows that priciples and theories of usability is relevant when evaluating interactive systems for the targeted group. However there is one concept that is more significant than the others. Our study shows that our targeted group is sensitive to time-consuming activities such as loading times etc. which has to do with the efficiency of the system.

The aim of this study has been to analyze how society is constructed in the workbook Möte med människor från andra kulturer, a popular material within the ?cultural competency? industry. The analysis has largely been carried out from the perspective of a pedagogy against oppression as it has been outlined by Kevin Kumashiro. I have found that the material combines discursive movements, which in complex and hybrid ways deconstruct, decenter, recenter and reproduce stereotypes and norms, through its normative language and pedagogy. A language constructing culture as cleanly demarcated, static and homogenous.

The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.

Information about vibration injuries as a preventive measure is beneficial to society as well as the individual. As early as after a few years work with machines that vibrate can cause young sensitive persons to develop vibration injuries.An evaluation has been done on a web page with focus on information about work related vibration injuries. As a part of the evaluation a user observation and interview study was performed with workers who worked in different occupations. The workers all used machine that vibrate as part of the work. A total of eleven workers participated in the study.

Denna studie undersökte skam och interpersonell känslighet. Kvinnor antogs använda sig mer av internaliserande skamhanteringsstrategier medan män mer av skamhanteringsstrategin Undvikande. Inga signifikanta skillnader gällande strategin Attackera andra förväntades. Kvinnor antogs vara mer interpersonellt känsliga än män. Vidare förväntades ett positivt samband mellan interpersonell känslighet och internaliserande skamhanteringsstrategier.

This study is a value chain analysis for timber in East Africa. It was commissioned by Vi Agroforestry, a nongovernmental organisation registered in Kenya, Rwanda, Uganda and Tanzania engaged in a rural development program that involves promoting tree planting and enterprise development (Vi Agroforestry, 2012). The purpose of the study was to identify and describe common value chains for timber in the countries where Vi Agroforestry operated. Value chain is a concept and a framework describing how to structure information regarding activities included in satisfying a certain customer need, e.g. procurement, logistics, transactions, production and marketing.

The aim of this study is to through six interviews, with six experienced, social workers?, in three cities, understand how the child?s position in the Swedish child protective services? enquiries has change, and the factors behind it. The aim is also to compare if the social workers? view of the child?s position in the enquire has change accordingly to Socialstyrelsens intentions of BBIC. The theoretical approaches that was used is the new institutionalism, the Shier?s pathways to participation and the term discretion.
