Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

The purpose of this study was to collect Swedish normative datafor Lundamaterialet for children aged 3:0-4:5 years. Another aim was toexamine the effectiveness of the test; if it elicits adequate responses fordeciding if a child has acquired a specific language structure or not.Normative data was collected for 195 children with typical languagedevelopment. Participants were recruited from pre-schools in themunicipalities of Göteborg, Mölndal, Härryda and Skövde. This studypresents normative data for 79 children constituting the three youngest halfyeargroups. Results show that the children had acquired more than half ofthe investigated phonological and grammatical structures and that the olderchildren had acquired more structures than the younger ones.

Sedan 1970-talet har större delen av världen upplevt en minskande löneandelen. Vi försöker förklara utvecklingen med en enklare modell bestående av två typer av arbetskraft. Vi visar att på kort sikt påverkar arbetskraftens sammansättning löneandelens utveckling vid arbetskrafts utbudschocker.Empirisk studie av paneldata ger inga statistiskt signifikanta resultat vilket skulle kunna orsakas av bristfällig data och att de länder för vilka data existerar är i hög grad homogena..

This thesis considers the problems associated with searches in insufficiently geographically tagged data. The thesis was carried out at Booli Search Technologies AB, a company developing a search engine for the Swedish real estate market.The aim of the thesis is to identify some areas of possible improvements of the company?s existing technical platform, perform a benchmarking among similar services, suggest possible solutions and lastly, build a prototype from one of the suggested solutions.The thesis starts out with defining the problems that the search engine faces: some areas are not possible to perform searches on, the users are not presented with the full search result that they expect, some results are placed incorrectly on the map associated with the search results and results are also not described with enough geographical information. These problems are due to the fact that the data retrieved at the indexing stage in the company?s information retrieval process are insufficient and incomplete.As a result of a benchmarking process and after discussing the results, severalinteresting solutions were identified.

The authors of this thesis have studied the handling of personal information in various kinds of organizations, because the perception is that the knowledge in this area is weak relative to the weight of the subject.The purpose of this paper has been partly to shed light on how knowledge of this area in the organizations that we have visited during the study but also to answer questions about handling, knowledge and security, and identification of individuals in different systems. What kind of problems the processing of these data creates and why these problems occur.In the beginning of our study we understood the importance of using the correct identifier and therefore chose also to examine what the various identifiers used by the organizations and why they chose these particular identifiers.In the qualitative analysis, Datainspektionen´s general rules and advice has been used as a basis together with the laws applicable to the organizations to get a good picture of how management of personal information is in these organizations.What we have found in this paper is that knowledge about how personal data is handled and what laws and rules are saying is very much dependent on how central the information is to these organization's activities. The police use so many different types of records for their organization to function well and they have very good knowledge of laws and regulations. In contrast, schools that do not handle as much of personal data themselves nor have the same knowledge among staff and do not have enough resources to cope with keeping the same knowledge base as the police. This is something that applies to all types of handling, depending on how important the information is for the organization, the better the security and knowledge in handling the data is..

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

Norra Militärdistriktet, MD N, har använt sig av geografiska informationssystem, GIS, under en längre tid. Dessa geografiska data lagras idag i en filstruktur som byggts ut allt eftersom data har blivit tillgänglig i digital form. Den geografiska informationen på MD N är i behov av en översyn för att få det mer strukturerat och användarvänligt. Målet med examensarbetet är en datamodell som ska kunna följas vid uppbyggnaden av MD N:s databas för metadata. Målet är även en modell som ska kunna följas vid omstrukturering av MD N:s geografiska grunddata.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

Genom att fusionera (sammanföra) data från olika sensorer kan ett resultat uppnås som ger mer än de enskilda sensorerna var för sig. Här utreds vilka sensorer och sensorfusionsmetoder som kan vara aktuella att använda för Scanias adaptiva farthållare (ACC). Den adaptiva farthållaren anpassar det egna fordonets hastighet inte bara till en förinställd hastighet utan även till framförvarande fordons hastighet. Scanias ACC-system använder idag en radar för måldetektering.Det finns ett antal algoritmer och arkitekturer som passar för sensorfusionssystem beroende på nivån hos sensordatan och användningsområdet. Minstakvadratmetoder kan användas då data ska matchas mot en fysisk modell, ofta med lågnivådata.

The aim of this study was to understand how evaluations are implemented and used in procured nursing homes for elderly. Our methodological approach consisted of a single-case study research. The case in this study was Växjö municipality. Three procured nursing homes for elderly were chosen in the municipality as examples of implementation and use of evaluation. The method for retrieving empirical data and the analyzing of it was based on triangulation.

Business Analytics används idag i ökad grad i organisationer som grund till beslutsfattande. Ett av villkoren för att kunna använda sig av Business Analytics för att utföra analyser av data från olika källor är att det finns interoperabilitet mellan dem. Syftet med den här studien är att undersöka om det är möjligt att skapa en IT-artefakt som kan hämta data ifrån flertalet XML-dokument med olika struktur för att uppnå semantisk interoperabilitet och på så vis möjliggöra för Business Analytics. Med olika struktur menar vi att benämningarna på taggarna skiljer sig språkmässigt men har samma semantiska betydelse. Lösningen skapas genom forskningsstrategin Design Science vilket innebär att en IT-artefakt utvecklas som kunskapsbidrag, och visar att en implementation av en lösning är möjlig för de semantiska problem vi identifierat.

The digital map product kNN-Sweden contains nationwide data of the country?s forest land. The estimated forest variables are mean age, mean tree height, volume per tree species and total volume. Today Södra Skog?s assessments of timber potentials are mainly based on experience rate and subjective assumptions.

It often occurs that the spirit regarding the future as a conservator is rather pessimistic. Howcome that there are so few employed conservators, when the need for conservation obviouslyis big? What kind of changes is needed for a better status regarding the conservation?This thesis concerns the development of the field of conservation in Sweden. What havehappened, what will happen and, particularly, what should happen? The information wasgathered from literature studies and interviews during the spring of 2010.

The aim of this bachelor thesis has been to examine and develop our own understanding about how young people in Sweden (16-29 years of age), take part in cultural activities. As librarians it is important to know what kind of activities and interests this particular group has. With Pierre Bourdieu?s theoretical framework towards habitus and capital we are interested to see if there is a connection between one?s cultural use and background, if different access to capital with or within groups has an affect or not. With both statistics and interviews with people within our target, we believe this data has been sufficient enough to conduct a good and valid study.

The purpose of this study was to describe the school situation of adolescents who were subject to multisystemic therapy in Sweden, and also if a change could be measured after treatment. Factors that preceded the need for treament were also investigated. The sample consisted of 83 adolescents, boys (65 %) and girls (35 %), with an average age of 14 years. The method used was a secondary data analysis using pre-treatment- and post-treatment data collected from a 7-month follow-up conducted by Lunds Universitet. Results showed that the adolescents were low in school performance and high in truancy at pre-treatment.
