Hantering av småskaligt elsystem med hjälp av GIS

Målet med detta examensarbete var att bygga en geografisk databas och en ArcView-applikation som hanterar data om ett elnät och dess komponenter. Arbetet har bestått av följande moment: ? Insamling av information ? Uppbyggnad av en geografisk databas i Access ? Uppbyggnad av en ArcView-applikation ? Koppling mellan databasen och ArcView ? Studier av befintliga lösningar inom området Arbetet resulterade i ett fungerande system som täcker ett litet geografiskt område. Grundtanken är att allt data skall lagras i databasen och presenteras i ArcView. Kopplingen mellan programvarorna är gjord med ODBC (Open DataBase Connectivity).

Konflikt i Tibet? - applicering av Johan Galtungs konfliktmodell på konflikten i Tibet.

Konflikt och vad som definieras som en våldsam konflikt är en central fråga i freds och konfliktforskning, men det är också en fråga som inte behandlas. Generellt definieras en våldsam konflikt som en konflikt enligt definitionen av Uppsala University Conflict Database med 1000 dödsoffer per år.Den här uppsatsen försöker titta på andar aspekter än den begränsade definitionen, genom att applicera Johan Galtungs konfliktmodell på ett fall som inte accepteras som en våldsam konflikt under definitionen av 1000 döda per år, nämligen Konflikten mellan Kina och Tibet. Galtung menar att det finns olika former av våld och att en för ensidig fokusering av det fysikiska eller direkta våldet begränsar uppfattningen av konflikten och att det gör att samhällsstrukturer uppfattas som fredliga trots att de har uppvisar flera andra icke fredliga..

Integritetsskyddet vid forskning : - En analys av det rättsliga stödet för att lämna ut och behandla känsliga personuppgifter vid registerforskning

The study explores collective action in Sweden between 1980 to 1995 using time-series data from the European Protest and Coercion Database. In spite of severe hardship during the crisis of the early 1990s, Swedish strike-rates declined. However, contention merely shifted from workplaces into the streets; there was indeed a protest movement against austerity, as shown by a series of large demonstrations, and some riots, between 1989 and 1993. Further analysis indicates this movement faded as it was increasingly chanelled into the electoral campaign of the labor pary; having won the 1994 election, the organised labor movement no longer had an interest in sustaining the protest movement against austerity..

Secondhandapparnas dilemma: milj?hj?ltar eller konsumtionsdrivare. Analys av secondhandappars inverkan p? unga vuxna kvinnors konsumtion

This thesis examines how marketing by secondhand apps affects young adult women's consumption habits, investigating whether these platforms promote or counteract overconsumption. While the secondhand market is considered more sustainable than buying new, these apps may still encourage overconsumption. The study focuses on the marketing strategies of three major secondhand apps in Sweden: Tradera, Sellpy, and Vinted, analyzing their impact on consumer behavior using the AIDA model (Attention, Interest, Desire, Action). Based on qualitative interviews with eleven women aged 20-27 and the authors observations of the apps marketing activities, the study finds that secondhand apps often emphasize environmental benefits and makes secondhand shopping accessible and appealing. However, the marketing tactics used by these apps, including frequent push notifications, targeted advertisements, and influencer collaborations, may lead to increased consumption. Overconsumption causes significant environmental damage, and while the secondhand market can mitigate these effects by extending the lifecycle of items, the emphasis on convenience end environmental benefits can inadvertently encourage more consumption. The study concludes that secondhand apps play a complex role in consumer behavior, balancing the potential for sustainability with the risk of promoting overconsumption.

Lokalisering av vågkraftanläggningar : Metodutveckling med GIS och fallstudie Bohuskusten

In this thesis work a Geographical Information System (GIS) based methodology to identify locations suitable for the installation of wave energy converters has been developed. Parameters of importance have been identified and a GIS-database has been set up, containing data about the marine environment. In a case study of the Swedish west coast the methodology has been applied, resulting in a number of maps showing possible areas. The results show that large areas are suitable for installation of wave energy converters, from a technical and economical point of view. When consideration is taken to other interests in the area, such as navigation, fishing and environmental protection, the size of the suitable area diminishes considerably.

Optimering av prestanda och utnyttjande av flertrådsteknik

The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..

Ekobyn, ett framtida koncept

Jönköping's municipality requested a diploma work witch would present the experiences, as arisen during the existence of the echo village Smeden.To recive information for the background, literature at the university library were searched at the database "Libris" with words like "echo village" and "ecological living".Data was retrieved from 28 questionnaires that were sent out to the inhabitants of the echo village Smeden. The questionnaires contained questions about experiences, opinions, ideas and thoughts about living in this echo village. The results were analyzed and presented by diagrams and tables and showed that the inhabitants where most unsatisfied with the sewer and the system of the toilet. In the opposite the inhabitants experienced that the remaining systems were in satisfactory and the majority of the inhabitants were very pleased with their living conditions.Conclusions of this study are that an echo village would be a suitable alternative to an ordinary living and that ecological living would be something that would work well even in the future. An important thing to remember is that the systems of the households must be easy for the inhabitants to maintain otherwise the environmental thinking would be in risk of failure if some don?t have the energy to manage this properly..

Miljö eller avkastning? : en investeringsjämförelse mellan gammal och ny energi

The purpose with this study is to investigate funds that are environmentally friendly. Environment issues has become a large subject that affects all aspects in today?s society.  It is a global issue which has affected the awareness of environmentally friendly products and its benefits for the environment.How has this awareness affected the financial market?  In this study the authors have looked at six environmentally sound funds and six energy funds to answer the question if it´s better to have your money in traditional energy or in renewable energy.This study is made in an quantitative way, the data has been gathered from the internet database Morningstar. The energy funds have had its biggest assets in companies dealing with oil, and the environmentally sound funds have had its biggest assets in renewable energy. Bye looking at the different funds rate of return and relating that to risk managing theories of Sharpe and Treynor, the authors compared the two types of funds.During the period that was looked at during this study ( third quarter of 2007 until third quarter 2010) the energy funds outperformed the environmentally sound funds in every aspect. .

Fritidshemsl?rares anv?ndning av mellanm?lets som en inl?rningsaktivitet.

I denna studie har vi unders?kt hur l?rare i fritidshem anv?nder sig av mellanm?let som en pedagogisk l?raktivitet i fritidshemmets lokaler f?r att fr?mja elevers l?rande, sociala f?rdigheter och det livsl?nga l?randet. Tidigare forskning visar att m?ltider erbjuder stora m?jligheter f?r l?rande och socialt samspel, men att det i praktiken ofta saknas strukturerade l?raktiviteter. M?nga fritidshemsl?rare ?r medvetna om mellanm?lets potential, men st?ter p? hinder, ofta (ramfaktorer) som brist p? tid, personal, planering och samarbete som g?r att egen organisering av mellanm?let i fritidshemmets lokaler ofta v?ljs bort.

Hyresbostadsfonder - ett placeringsalternativ för välbärgade?

Hyresbostadsfonder är en ny placeringsform i Sverige som erbjuder privatpersoner, företag och institutioner att äga hyresfastigheter och erhålla avkastning från förvaltningsöverskott och värdeökning. I denna studie jämförs aktie- och obligationsfonder med en simulerad hyresbostadsfond ur ett risk kontra avkastningsperspektiv. Fonden baseras på data över den svenska fastighetsmarknaden från Svenskt Fastighetsindex och Investment Property Database, därför att placeringsformen är ny och det råder brist på historisk data från verkliga aktörer.Målet med studien är att besvara om hyresbostadsfonder är ett konkurrenskraftigt alternativ till aktie- och obligationsfonder. Utöver finansiella jämförelser redogör författarna eventuella dolda risker och nackdelar med placeringsformen.Resultatet från studien visar att hyresbostadsfonden har presterat bättre än både aktie- och obligationsfonderna under perioden 1988-2008. Bidragande faktorer till denna utveckling har identifierats och redovisats.

Migration av Excelbaserat system till webbsystem : Implementation av ett planeringsverktyg inom telekom

Syftet med examensarbetet är att redogöra för hur ett system baserat påExcel kan migreras till en webb- och databasplattform. Initiativtagare tillarbetet är en avdelning vid Ericsson AB i Linköping. Avdelningen använderExcel till datalagring och presentation av testmiljöbeskrivningar ochönskade migrera detta Excelbaserade system till ett webbaserat dito. Någraav de problem som uppkommer vid migration är: nya säkerhetsrisker; hurdata ska ordnas i databasen för att uppnå sökbarhet och versionshanteringsamt hur presentation av data ska styras.För att svara på dessa frågor har vi utfört en förstudie och enimplementation av systemet Node Network Plan Database (NNP DB),vilket ämnar ersätta det Excelbaserade systemet. Rapporten beskriver hur:säkerhetsrisker har minimerats genom att införa lämpliga skydd; databasenhar designats för att uppnå sökbarhet och versionshantering; presentation avdata kan styras.NNP DB visar sig vara effektivare, ur ett tidsperspektiv, än detExcelbaserade systemet.

Elektroniskt tillgängliggörande : En komparativ utvärdering av Google scholar och Summon

Electronic availability of information resources has increasingly become an important part of academic libraries everyday vocation. This is a fact that puts impetus on the libraries to know more about the way in which electronic information is being dispersed and handled. This thesis aims to comparatively evaluate Uppsala university library´s own metadata system Summon with the publicly available equivalent Google scholar. The evaluation is based on Péter Jacsó´s theories on database evaluation which concretely puts focus on Summon and Google scholar via the use and application of ten different criteria. The uses of precision and relevance criteria were also implemented as additional evaluation tools.
