I huvudet på en naturkunskapslärare : Elevernas intresse- problem eller resurs?

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Matematik och ingenjören : Utveckling av en aktivitet för att öka elevers motivation för matematik

This thesis primarily includes a study on whether companies can develop a mathematical activity that supports students' motivation in mathematics. The work was done together with Midroc Electro, a company that pays attention to the difficulty of recruiting and therefore was interested in investigating how the business world would be able to contribute.The thesis can be divided into three stages. The first part comprised by a exploration into research on student motivation regarding mathematics as well as numerous interviews with engineers to see how the research findings did fit with Midroc Electros reality. In these studies it became clear that the student who aims for a profession whose education or work requires math belongs to the group of students who primarily manage their studies in mathematics, that is, those that have the greatest motivation to work hard and complete their studies.Research information and interviews were compared and resulted in the thesis second part, Midroc Challenge. An activity where students primarily came to learn about the engineering profession and secondly how mathematics can be used in the engineering profession.

E-böcker och bibliotek : En kritisk diskursanalys av Biblioteksbladet 2005-2011

The aim of this two years master´s thesis is to examine discourses about electronic books in relation to libraries that occur in the Swedish library journal Biblioteksbladet by using critical discourse analysis (CDA). The thesis also aims to discuss changes in the discourse practice, and discuss the relationship between discourse practice and social practice in the field of library and information science (LIS). A main point of CDA is that language is a form of social practice that helps shape social reality. Furthermore the concept of ideology, as understood with-in CDA, brings understanding to the way discursive events help reproduce and transform social relations of pow-er. The text samples span from 2005 up to and including 2011 and were examined by using Norman Fairclough´s three-dimensional conception of discourse, which allows for interpretation of text on a linguistic, discursive and social level.The result of the analysis showed that there are several different discourses about electronic books and li-braries, none of which can be said to be particularly representative.

Energieffektiviserande åtgärderpå Robertsfors VA-nät : En förstudie av vilka energieffektiviserande åtgärdersom kan göras på pumpstationer och reningsverk

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

En utredning av tekniken "mobile mapping" i kommunal verksamhet

This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.

Skilda frälsare i samma kläder : En studie om Mithras och Messias funktioner och likheter

It has since long been noticed that savior figures from different religions have reminded of each other, and there are different theories trying to explain why. This study examines religions operating in the same culture, and in this case, judaism and zoroastrianism, and their influence on each other. In particular, focus is on zoroastrianism's image of the savior figure Mithra, and how this representation may have influenced the description of the Messiah in the Talmud. How are the two figures represented in the scriptures and what similarities can be identified?By a thorough content analysis the studie examines the Avesta of zoroastrianism and the Talmud from judaism.

Skadeanalys och omkonstruktion av HMS Belos A-ram

In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.

Nätverk och förebilder : en studie om betydelsen för entreprenöriella kvinnor

Background: Of those who start companies, only about 30 % are women. Women's companies also often have both fewer employees and lower turnover. Several efforts are therefore being made to try to influence and encourage more women to start businesses and to get them to expand. Two of these ventures are special network for women and about women entrepreneurs as role models, something that also the theories believe is very important for a more egalitarian business. While entrepreneurship is encouraged for growth in the community, it also has a male character, something that needs to be considered.Purpose: As both the EU and the Swedish government through measures such as Tillväxtverket, is investing large sums to promote networking and role models, we intended to analyze the importance of networking and role models for entrepreneurial women.

Wobblerpump

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

Avbrottsfri Kraft med användning av ultrakondensatorer

The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.

IMPLEMENTERING AV PHONGLJUSSÄTTNINGI 2D-SPELMILJÖ

Under de senaste åren har en ny trend inom spelindustrin uppstått då en stor del av spelen har gåtttillbaka till de tvådimensionella miljöerna som var vanligare i tv-spelens barndom, detta tack vareatt mobiltelefoner och deras spel har tagit allt större plats på marknaden och de är oftatvådimensionella på grund av sin begränsade hårdvara. De tvådimensionella spelen har enligttradition inte haft någon dynamisk ljussättning, utan de har bestått utav färdig grafik medförutbestämda intensiteter vilket gör att spelen kan se platta ut.Men inom andra områden av spelindustrin, framförallt tredimensionella spel, har utvecklingen avdynamiska ljussättningsmetoder kommit långt. Problemet med dessa metoder är att de kräverobjektens normaler, vilka normalt inte finns tillgängligt i tvådimensionella bilder.Idag är mobiltelefonerna kraftfulla och klarar av mycket tyngre beräkningar än vad de gjorde förbara några år sedan. Därför undersökte vi möjligheten att implementera dynamisk ljussättning i etttvådimensionellt spel på androidbaserade mobiltelefoner. För att genomföra detta krävdes också attvi undersökte metoder för att generera normaler för tvådimensionell grafik.För att ett fullständigt spel skulle kunna skapas så implementerades också saker somkollisionshantering, artificiell intelligens och procedurell generering av banor..

Lost in place : on place theory and landscape architecture

Place is on the one hand a commonsense everyday word with diversely connotative meanings, and on the other a contested concept with different interpretations across a broad range of academic disciplines and discourses. This thesis researches theories of place and their implications for the theory and design practice of landscape architecture. Responding to problems of insufficient theoretical grounding and inconsistent use of the concept of place within the discipline presently, it argues the need for a theory of place better articulated in relation to landscape architecture. It seeks to contribute to such theory formation by drawing on ideas from related disciplines ? tracing diverse understandings of place beyond the commonsense meanings of the word and into the deeper reaches of place theory as tools to explain physical, social and spiritual aspects of the environment, and human relationships with it.

Ämnet Svenska : En kritisk diskursanalys av svenskämnets kursplaner i Lpo 94 och Lgr 11

The purpose of this study is to investigate how the subject Swedish is being constructed in syllabuses for the subject. The study includes the syllabuses for the subject Swedish from the Swedish curriculums Lgr 11 and Lpo 94. These are investigated in order to show what conceptions of the subject, i.e. the purpose, content and work models of the subject you can spot in these, and in what direction the perception of knowledge has changed. For the analysis Faircloughs critical discourse analysis and three dimensional model is being used.
