Optimering av blandning och lagerhållning av avfallsbränsle : Optimering av avfallsbränsleblandning och lagerhållning av importerat avfallsbränsle vid Vattenfalls fjärrvärmeverk i Uppsala
Fjärrvärmebranschen i Sverige har sedan mitten av 1990-talet varit i en stagnationsfas, där mängden producerad och förbrukad energi i stort sett varit konstant, trots stora investeringar i fjärrvärmenätet. Samtidigt har den höga andelen återvinning gjort att det råder brist på avfallsbränsle till energiåtervinning i Sverige. I kombination med hög konkurrens om avfallsbränslet har detta medfört att aktörerna på marknaden tvingats se sig om efter nya vägar att tillfredsställa behovet av bränsle, vilket lett till att det idag importeras stora mängder avfall för energiåtervinning från utlandet. Vid Vattenfalls fjärrvärmeverk i Uppsala har det mellan åren 2006-2013 återvunnits i snitt drygt 360 000 ton avfall per år. En stor del av detta hämtas in från lokala kunder, både kommuner och privata aktörer, men man har på senare tid även behövt börja importera avfall för att tillfredsställa energibehovet.
Att göra eller inte göra : Hur kontroll och nyfikenhet påverkar regelverket på Facebook
This paper is a literature study on search engine optimization (SEO) considering the leader of the search engine market: Google. There´s an introductory background description of Google and its methods of crawling the Internet and indexing the web pages, along with a brief review of the famous PageRank algorithm. The purpose of this paper is to describe the major important methods for improved rankings on Google´s result lists. These methods could be categorized as on-page methods tied to the website to be optimized or off-page methods that are external to the website such as link development. Furthermore the most common unethical methods are described, known as ?black hat?, which is the secondary purpose of the text.
Framtagande av metoder och rutiner för säkerställande av kompetens : inom miljö, arbetsmiljö och kvalitet
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
Annonser i nättidningar ? kvalitet och placering i målorienterad sökning
This study investigated how banner ads, depending on its quality and placement,can capture a user's attention while searching for editorial content in an online newspaper. Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.

3D-modellering i AutoCAD -att skapa en digital huskonstruktion
3D-modelling in AutoCAD This thesis is done in cooperation with LB-Hus in Bromölla, and have aimed to establish a digital AutoCAD model of one of the company?s house types and to find out what opportunities there are to do visualisations in the form of images directly from the programme. Modeling has been carried out so that the very construction of the house is included. Interiors and installations, with the exception of the ventilation system, have been left out in the model. The model has been created with solid models after a comparative study made between solid models and surface models to find out which option in this case was the easiest to handle and took up the least space.
Identitetssökandet hos unga flickor i 2010 års barn- och ungdomslitteratur
My ambition with his exam is to study how young girls are being depicted in swedish novels of 2010. I have analyzed how the identity and the search for identity are produced in these books. To be able to make my analysis of these books I have used Maria Nikolajeva?s book Barnbokens byggklossar. From wich I have worked out a few questions that I have used my analysis in the portrayal of these girls.
Högskolebibliotekariers informationssökning : en studie i hur högskolebibliotekarier söker information till sig själva och för andra
The purpose of this thesis is to examine how academic librarians seek information for themselves and for others, and what differences exist. The terms self-generated and imposed information seeking is used to describe the two different types of information seeking. Step 2 ? define and understand the problem, step 3 ? choose a search system and step 4 ? formulate a query of Marchionini?s information-seeking model forms the basis of the theoretical framework, which is supplemented with Soergel and Katz. Qualitative interviews with eight academic librarians were conducted and analyzed in order to gather empirical facts.

Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor
This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.
KVARTERSINTEGRERING
Through the different stages of life people have different requirements for their homes. The requirements changes depending on people?s life situation, lifestyleand age. Depending on where people are in life they live in different place, often in areas with other people who are in the same stage of life. In Sweden, this separation has always been noticeable, sometimes more than other.
Klassifikation på webben
The thesis concerns the use of classification schemes for organising resources in subject-based hierarchical search-services on the web. The aim is to investigate the different kinds of classification that are used, which fall into two groups: established respectively new classification schemes. This is attained by studying literature and the websites of each search-service. The prospects for using classification in a web-environment are discussed and divided into three major groups: browsing, control and cross-classification. One question at issue concerns how an established scheme manages to organise web-resources and whether this classification differs from the classification of new schemes and in what way.
Förslag till bebyggelse och park i kvarteret Seminariet i Uppsala
In the urban planning debate of today, two strategies for city development stand out as each other's opposites, urban sprawl and smart growth. This thesis concerns a development project of the latter kind and aims to give an alternative proposal to new buildings and a park in a Swedish city block. The term sprawl is used for new developments on virgin soil on the outskirts of cities leading to a city spreading, while smart growth stand for increased city density through development on re-used land within the city boundaries. The latter are often seen as more sustainable in many levels and are also shown to have positive effects on a number of city functions. At the same time smart growth has negative consequences on other aspects of the city such as public open spaces.
MERCOSUR SOM ETT NYTT REGIONALT BLOCK : Ett steg närmare en Sydamerikansk Union?
Uppsatsen har till syfte att undersöka huruvida MERCOSUR är en aktör på den internationella arenan och om dess tilltagande utveckling kommer kunna bidra till ett ökat interregionalt samarbete. Uppsatsen ska uppnå syftet genom att svara på två frågeställningar: 1) Kan MERCOSUR definieras som en aktör på den internationella arenan? 2) Kan MERCOSUR ses som ett nytt regionalt block och därmed ingå i interregionala samarbeten?Uppsatsen går igenom nya regionala blockens uppkomst och vad som skiljer dem åt från andra frihandels avtal. Uppsatsen är en komparativ analys som använder sig av två modeller för att svara på frågeställningarna. Den ena är Björn Hettnes dynamiska modell som beskriver en förändringsprocess.
Kontinuerlig RFID-detektering för batteridrivna system
This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.
