I många sammanhang är det önskvärt att importera data från textfiler, excelfiler och liknande till en databas. För detta krävs att data i något skede översätts till en ER-modell (Entity Relationship), en modell som beskriver relevanta delar i ett databasschema. Modellen för hur denna översättning ser ut varierar från fall till fall.I det här examensarbetet har en applikation tagits fram för import av data till en ER-modell ur ett modellperspektiv i linje med Model Driven Architecture (MDA) ?. Vinsten ligger i att använda en metamodell som beskriver hur olika modeller för transformering från tabelldata till en ER-modell får se ut.

The purpose of this study is to investigate what teachers in preschool thinks of play and how they use play to create learning. In my study I have proceeded from three questions which are: How do the teachers describe how the children learn through play? How do the teachers describe their participation in the children´s play? How do the teachers describe what they do to involve learning in play? To examine my purpose and the questions at issue, qualitative interviews were done with three different teachers. The interviews were transcribed and analyzed and the result showed that teachers´opinion and experiences of learning through play. The result shows that teachers belive that playing is very important and that it should be fun and joyful.

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

De senaste åren har molekylärbiologisk data växt explosionsartat. Ny teknik gör att information kan härledas ur data snabbare och mer än tidigare. Faktum är att det tillkommer så mycket ny data att de nya resultaten inte längre kan publiceras i artiklar. Dessa sekvenser av data finns istället bara åtkomliga i speciella databaser. Dessa databaser är tillgängliga för allmänheten dels genom att ladda ned dem eller att använda en Internet browser.Det har, för ett par år sedan, kommit en ny standard för att strukturera upp och lagra data på.

The aim was to find out teachers in Swedish as a second language in primary schools view on how they work with a language development teaching in a multicultural environment. I did a semi-structured interview where I both made questions before the interview and also used individualized follow-up questions during my interview. I did that because I really wanted to get answers to the subject and the aim of the essay. Two teachers in Swedish as a second language have been interviewed. The result shows that a holistic approach to language development is important, where great emphasis lies on understanding. Teachers say that communication and interaction are key factors and that it is important with good linguistically appropriate and understandable texts where the words/concepts are learned and used in the right context. .

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Dagens informationssamhälle har bidragit till att människor, maskiner och företag genererar och lagrar stora mängder data. Hanteringen och bearbetningen av de stora datamängderna har fått samlingsnamnet Big Data.De stora datamängderna ökar bland annat möjligheterna att bedriva kunskapsbaserad verksamhetsutveckling. Med traditionella metoder för insamling och analys av data har kunskapsbaserad verksamhetsutveckling tillämpats genom att skicka ut resurskrävande marknadsundersökningar och kartläggningar, ofta genomförda av specialiserade undersökningsföretag. Efterhand som analyser av samhällets befintliga datamängder blir allt värdefullare,har undersökningsföretagen därmed en stor utvecklingsmöjlighet att vaska guld ifrån samhällets enorma datamängder. Studien är genomförd som en explorativ fallstudie som undersöker hur svenska undersökningsföretag arbetar med Big Data och identifierar några av de utmaningar de står inför tillämpningen av Big Data analyser i verksamheten. Resultatet visar att de deltagande undersökningsföretagen använder Big Data som verktyg för att effektivisera befintliga processer och i viss mån komplettera traditionella undersökningar.

Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

The aim of the present study was to estimate the correlation between Euro NCAP pedestrian rating scores and injury outcome in real-life car to pedestrian crashes, with special focus on long-term disability. The study also surveyed most frequently injured body regions and risk differences for specific elements of pedestrians hit by cars. Another aim was to determine whether Brake Assist systems affect the injury outcome in real-life car to pedestrian crashes and to estimate the effect in injury reduction of a high Euro NCAP ranking score combined with Brake Assist.In the current study, the Euro NCAP pedestrian scoring was compared with the real-life outcome in pedestrian crashes that occurred in Sweden 2003-2010. The real-life crash data was obtained from the Data Acquisition system STRADA, which combines police records and hospital admission data. The medical data consisted of International Statistical Classification of Diseases and Related Health Problems (ICD) diagnoses and Abbreviated Injury Scale (AIS) scoring.

The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.

Sverige har länge haft en god kultur av öppenhet i den offentliga sektorn tack vareoffentlighetsprincipen. Men med allt större tekniska framsteg och ökade krav på datatillgängligheträcker den klassiska öppenheten inte längre till. Det finns redan mycket intressant offentlig data iSverige, men i de flesta fall är den antingen sparad i format som är svåra att avläsa digitalt eller fördyr att använda.I denna uppsats undersöks hur ett API kan utvecklas, användas och integreras med andra API:er föratt öppna upp ovan nämnda data på ett bättre sätt och göra den mer tillgänglig för potentiellaanvändare. Vidare undersöks också PSI-direktivets egentliga nytta och hur det tillsammans medoffentlighetsprincipen kan bidra till den nya öppenheten. Med koppling till denna uppsats har ävenen prototyp utvecklats för att ge exempel på hur man kan kombinera olika API:er för att visualiserageografisk data samt hur ett API kan byggas ovanpå visualiseringen för att göra denna data mertillgänglig..

This Master's thesis discusses the freedom of speech, the right to freedom of opinion and expression, freedom to hold opinions without interference and to seek, receive and impart information and ideas in the context of public libraries in Sweden. The scope of this thesis is to examine the acquisition and maintenance of the literature about the killing of Sweden's Prime Minister Olof Palme 1986. This literature will serve as an instrument to measure the extent to which Swedish public libraries adhere to the rules set by the Swedish parliament, United Nations' universal declaration of human rights article 19, UNESCO's public library manifesto and the principles of the Federation of Library Associations and Institutions..
