Svensk delnormering av Lundamaterialet för åldrarna 3:0?5:11 år och undersökning av materialets effektivitet

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.

Löneandelens förändring 1975-2010 : Teori och empiri

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..

EMC problematik och el-kvalitet i elkraftnät

The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.

Områdessökning i geografiskt associerad data

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.

Personuppgifteshantering och identifiering inom myndighet, skola och förtag

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..

Export of wood pellets from British Columbia : a study about the production environment and international competitiveness of wood pellets from British Columbia

The global wood pellet market has seen a rapid growth after the adoption of the Kyoto protocol and the renewable energy incentives created within the European Union. The global consumption of wood pellets reached 13,5 million tonnes in 2010 and several experts estimate the consumption to be between 35-50 million tonnes by 2020. These forescasts raise the questions which regions that can supply this vast amount of wood pellets and what the conditions are for producing it. This study evaluates the conditions for wood pellet production and export from British Columbia, on Canada?s west coast, focusing on existing industry structure, raw material supply and the distribution chain.

Effektivisera generering av parameterfiler för betalterminaler

Denna rapport återger arbetsprocessen kring att utvärdera datalagringsstruktur och förbättra prestanda för generering av parameterfiler för kortterminaler. Arbetet utfördes på plats hos Esplanad AB, ett företag som bland annat arbetar med säkerhetslösningar och distribution av inställningar för betalstationer.Uppgiften bestod av att utvärdera möjligheter till att förbättra databasen som sparar alla inställningarna för betalsystemen, samt att förbättra kodstruktur och prestanda för programmet som genererar filerna.Rapporten beskriver testning av prestanda, både på Esplanads gamla program för att generera parameterfiler och det nya som konstruerades. En lösning presenteras som inkluderar förbättring av filgenereringens prestanda och en ny struktur på databasen för ökad skalbarhet.Tester visar att det nya systemet klarar av att skapa parameterfiler på TLV-format ungefär 16 gånger snabbare. Den föreslagna lösningen implementerar parallella processer och replikering av databasen..

Fastställande av referensintervall för fibrinogen i plasma hos friska föl :

Establishing a reference interval for plasma fibrinogen in foals Fibrinogen concentrations were analysed in EDTA preserved blood plasma samples from 34 thoroughbred foals born in 2001 and 2002 at one stud farm. The foals were between 0 and 240 days old at the time of the sampling, and there were 19 fillies and 12 stallions in the group. The foals were examined for clinical symptoms of disease and their body temperature was measured before blood was sampled from the jugular vein. From totally 156 blood samples, 31 were selected as originating from clinically healthy foals, and used to determine a reference range for thoroughbred foals. Samples originating from foals showing clinical symptoms of disease or an abnormal body temperature at the time of sampling, were classified as coming from unhealthy animals.

Rumslig fördelning av grov gammal tall i Uppsala stad med tallticka som indikator på höga naturvärden :

Fragmentation and reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning. The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.

Att fråga eller inte fråga, det är frågan : En studie av frågor mellan lärare och elever under kemilektioner

In addition, interviews have been made with the teachers and the students have answered a questionnaire. The result show that a high number of questions are asked, more than one per minute and that both teachers and students ask the same amount of questions. This contradicts earlier findings were teachers questions dominate.

Datamodell för metadata och grunddata över MD Ns geografiska information

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.

Sensorfusion för ACC-System

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.

Semantisk interoperabilitet för hantering av XML

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.

Kvävemineralisering från stallgödsel beroende på olika grad av inblandning i mark

The impact of the distribution in the soil volume of two farm manures on the net mineralization and immobilization processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil (MIX). During the two weeks of incubation, few significant differences in net mineralization were seen between TOP, MID and MIX. However, there was a tendency that MIX led to a larger net immobilization of N than placement at one point (TOP and MID). This is also the result in the literature.
