Grönskande balkongkonstruktioner : Jämförande arkivstudie av balkongkonstruktioner anpassade för urban odling

Urban agriculture is a current topic and this study examines the possibility of cultivating on balconies in the city. The study was performed at Uppsala University and examines, from a structural engineering perspective, how different existing balcony/terrace structures are affected by cultivation. A cultivation balcony defined in the study as a balcony/terrace which is specifically designed for cultivation. Three units of study have been selected according to this criterion. Four factors were examined, these were loads, moisture/water, economy and cultivation.

Att driva etablerad Buddhistisk och Muslimsk verskamhet i Karlstad kommun : De verksammas uppfattning om möjligheter och svårigheter som religiös i Karlstad

I wanted to focus this essay on the operative?s perspective of running religious organizations in the city of Karlstad and to see positive and negative aspects of their day-to-day life working with their organization, following up with a comparison of the difference and the similarities between those groups. After delimitating which groups I was going to examine, I implemented a qualitative study of four people, from two different religious groups, whom I performed interviews with. My method of performing these interviews and understanding the perspective of the informants, I had a semi structured interview guide along with a recent study that was opting for similar conclusions, only in a different county and with different input perspective. The result of my study showed a difference in establishment of their region but with a lot of similarities in problems with their religious and structural premises.

Bearbetningsmaskin för fälgar i kolfiberkomposit

Detta examensarbete har utförts på uppdrag av Koenigsegg Automotive AB, som utvecklar, tillverkar och säljer högpresterande sportbilar. Företaget erbjuder fälgar tillverkade helt i kolfiberkomposit, som ger betydande viktbesparingar i jämförelse med traditionella metallfälgar.Efter tillverkningen kräver fälgarna viss bearbetning vid anläggningsytan mellan fälg och däck. Syftet med examensarbetet har varit att undersöka möjligheten att utföra bearbetningen av fälgarna in-house i Ängelholm, och målet har varit att konstruera en maskin för detta ändamål.Projektet inleddes med en litteratursökning, där svårigheter och möjligheter gällande bearbetning av kolfiberkompositer undersöktes. Till följd av de undersökningar som gjordes, valdes bearbetningsmetoden svarvfräsning och ett antal konstuktionskoncept genererades. Genom ett antal utvärderingar utvecklades ett speciellt koncept vidare till ett komplett produktförslag.Produktförslaget är komplett med analyser, beräkningar samt tillverkningsunderlag, som ger uppdragsgivaren bättre insikt i sina möjligheter.

Skogsåkeriägares inställning till organisationsförändringar :

There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.

KBE I PRODUKTUTVECKLING PÅ SCANIA : En undersökning av potentialen i CATIA Knowledgeware

Övergången från CATIA V4 till CATIA V5 innebär nya möjligheter för konstruktörerna på Scania att arbeta med Knowledge Based Engineering, KBE, för att effektivisera och kvalitets-säkra sitt arbete. Då CATIA V5 är en ny plattform som innehåller verktyg med samlingsnamnet knowledgware, för att bygga in kunskap i modeller ville Scania undersöka potentialen i att arbeta med KBE, och hur detta skulle kunna ske på Scania. Vid traditionell produktutveckling tas en helt ny artikel fram vid behov och ofta innebär detta att arbete som tidigare utförts, görs om igen. Syftet med arbetet är därför att undersöka huruvida KBE i CATIA V5 kan erbjuda möjligheter att återanvända kunskap från tidigare arbete och samtidigt kvalitetssäkra denna, samt utreda vilka knowledgewarelicenser som i så fall kan vara lämpliga för Scania.För att göra detta har en litteraturstudie genomförts för att undersöka vad som har gjorts inom området, och även en intervjustudie har utförts inom R&D på Scania. Vidare har sakkunniga på Linköpings Universitet och Tekniska Högskolan i Jönköping intervjuats.

Valet inför valet : En studie om hur svenska förstagångsväljare väljer att ta del av politisk information

Problem statement and purpose:The purpose of this study was to analyze in what way first-time voters chose to take part of political information. The questions we aimed to answer was how first-time voters use media and other information channels for political purposes, what importance and trust the first-time voters give the different information channels and finally which indicators there is for that structural or individual factors affect the media consumption and political interest.Method and material:We did interviews with twelve 18 years old first-time voters from six different high school programs in Sundsvall, Sweden.Results:The study showed that the premier source of political information were traditional news media, in particular the debates on TV. It?s also in the debates the first-time voter?s trust the most. Even though the social medias are constantly present in their everyday life and even though the first-time voters believe the social medias have potential for engaging young people politically, the possibilities are only taken in advantage by people who are already politically interested.

Fäste för ramar

Syftet med detta examensarbete har varit att ta fram ett snabbfäste för ramar åt Roxtec International AB på Verkö i Karlskrona. Examensarbetet har följt metoden för Integrerad produktutveckling av Fredy Olsson. Av denna metod har två områden berörts: Principkonstruktion samt Primärkonstruktion. Primärkonstruktionen är uppdelad i två delar där den ena behandlar komponentval och detaljkonstruktion, och den andra innefattar framtagning av prototyp och en ekonomisk kalkyl. Problemställningen var följande: Att ta fram ett snabbfäste för små ramar. Ramarna används till kabelgenomföring till elskåp och liknande applikationer, och de kommer att innehålla Multidiametermoduler med inneslutna kablar och kompressionsenhet. Idag fästs ramarna med hjälp av skruvar och muttrar men det nya fästet får inte utgöras av skruvar, sprintar, fjädrar och de får ej heller svetsas fast. Fästet ska vara av enkel konstruktion, lätt att montera och demontera utan hjälp av verktyg.
