This thesis discusses main problems associated with dictionary-based Cross-Language Information Retrieval as lexical and translational ambiguity of query terms, translation of compounds and phrases, dictionary limitation. The purpose of the study is to investigate how query structure influences the effectiveness of CLIR regarding performance of three query types: original query, unstructured query and structured query. Query structuring refers to the application of #syn-operator to group query terms. The study comprises an experiment that was performed in the InQuery IR system with TrecUta database that contains 550,000 news articles from different American newspapers. 24 topics were used for the experiment.

This paper is a comparing study of the retrieval effectiveness of the search engines Google, Google Scholar and Scirus. The aim is to find out how good they are at retrieving relevant academic material in the research-field of Library and Information science. The thirty search questions where based on actual information needs collected from exams within the field of Library and Information Science. This method was used to prevent that none of the search engines were given an advantage because of construction of the information needs. The first twenty retrieved documents on the retrieval lists are examined for academic content and relevance.

There is always an endeavor to govern the initial products in the plant cultivation with precision in order to keep down the expenditure and in order to decrease environmental impact. Initial phosphorus fertilizer can then be one possibility in order to keep down the fertilizer cost and to decrease environmental impact. This exam study includes a literature study about location of fertilizer and which effects this give and two field experiments. The aim with initial phosphorus fertilizer to autumn wheat is to accelerate the root growth and to give the crop a big root system before the growth stagnates before the winter. Easy to access phosphorus favours the root growth.

This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.

Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.

The purpose of this essay is to examine if there is any difference in the style of conversation between a municipal politician and a politician in parliament? In order to answer this question I have created two sub-questions that are more precise. The first question is: Are the municipal politicians more open to cooperate with politicians from other parties than the politicians from parliament? And the second question is: Is the rhetoric between the politicians in parliament different than the rhetoric between the municipal politicians?My study is a comparative case study with two different groups of politicians. With the help of a survey I have tried to examine if there are differences in the use of language in the daily work for the politicians.

Detta examensarbete i landskapsarkitektur behandlar ämnet urban odling med avsikten att identifiera vilka möjligheter och begränsningar det finns med odling i staden. Målet med examensarbetet är att uppnå en större förståelse och kunskap inom detta ämne. Varvsstaden i Malmö har valts som ett exempel för att illustrera hur odlingar skulle kunna implementeras i en central stadsdel som är under utveckling.Litteraturstudier har legat till grund för en kunskapsöversikt av olika aspekter av urban odling. En kvalitativ miniundersökning har utförts för att ta reda på hur nyckelpersoner i Malmö från de tre kategorierna; politiker, tjänstemän samt brukare ser på urban odling och dess möjligheter och begränsningar. Kunskapsöversikten om urban odling i allmänhet och beskrivningarna om Varvsstaden i Malmö har fungerat som underlag till idéskisser för hur odling i Varvsstaden skulle kunna se ut.Resultatet av examensarbetet visar på att det finns många möjligheter med urban odling och att det finns mycket att vinna genom att odla i staden.

This thesis is based on an exhibition at the county museum Upplandsmuseet in Uppsala, Sweden. During an internship at this museum I got a chance to produce an exhibition, with some guidance from the museum staff. This exhibition was created with the purpose of teaching about agriculture in the late 19th century and also about the magnificent workmanship of Alrik Klingberg, who have carved these wooden objects for over 50 years. Each one of the objects possesses a story and a memory. The memories that Alrik Klingberg has incorporated into the objects are mainly from his childhood at a croft in northern Uppland.

When I began my studies at Gammelkroppa forest school I started to think about an appropriate thesis. There was much discussion about the wild grazing damage during that period. I was at that time a part of Boo property and helped at their great hunts. They had the dual uses of wildlife and forest. I decided that I want to study how big the wild grazing damages are and if we can reduce them.

The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.

Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.

Studies of modern communication media such as Cell Phones and so called Instant Messengers are popular today. This study focused on these modern techniques, focused on parents as a target group and on what is important for them in everyday communication.By exploratory using three focus groups it became clear that the children, and the link to them was the absolute most important thing for the parents. It became clear that this link to a great extent today exists through the mobile phone.In a following study a Mobile Instant Messenger called My Friends was introduced. It was used by two families during two weeks to see how it would change the communication within the family. The focus was to see how problems with availability were handled, it turned out that:My friends had a more obvious way of indicating availability than the Cell Phone had.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Stadsodling kan fungera som mötesplatser i staden för att främja en social samvaro och en socialt hållbar utveckling. Syftet med examensarbetet var att studera hur detta kan se ut på olika stadsodlingar i Göteborg, och hur deltagarna själva upplever odlingen som mötesplats och hur en gemenskap kan se ut. Bakgrunden för examensarbetet ligger i ett personligt intresse av odling i staden och hur människan tar sin stad i anspråk. Vad gör människan i sin stad? Intervjuer har genomförts med deltagare från sex olika stadsodlingar, på olika platser i Göteborg.
