Elgitarrskolan : En webbsida med inslag av interaktivitet

Elgitarrskolan är ett försök att skapa en webbsida med inslag av interaktivitet. Sidan är tänkt att fungera som en lärande miljö där besökaren ska lära sig att spela elgitarr, eller att vidareutveckla ditt spelande. Förutom själva spelandet ska sidan också ge gästen information om elgitarren och kringutrustning, med en del tekniska specifikationer, historik m.m. Elgitarrskolan är ett försök att sprida specifik kunskap genom att integrera flera olika medier till en fungerande enhet. Med hjälp av text, grafik, animationer, ljud, video och interaktiva element har jag försökt att göra informationen så lättillgänglig som möjligt och samtidigt intressant.

Andra har gått före : En studie av identitetsskapande bland överlevare av sexuella övergrepp

Den här uppsatsen handlar om unga vuxnas identitetsskapande i dagens västerländska samhälle. Via två uttryck - kläder och kulturkonsumtion - undersöker jag hur individen bygger upp sin identitet och kommunicerar den till omvärlden. Mitt syfte är att undersöka hur stil och smak (i kläder och kulturkonsumtion) utgör meningsbärande komponenter i det egna identitetsskapandet. Stil och smak utgör två viktiga element, eftersom det är genom dessa begrepp som individen avgränsar och definierar både sig själv och andra. I den avslutande diskussionen utgår jag vidare från Ziehes teorier och analyserar sambandet mellan de ungas jakt på identitet och dagens omvälvande samhällsförhållanden.

Towards an Understanding of Heterosexual Risk-Taking Behaviour Among Adolescents in Lusaka Zambia

This thesis investigates the underlying factors behind sexual risk-taking and non-risk-taking behavior with regard to Sexual Reproductive Health (SRH) among adolescents in Lusaka, Zambia. The Qualitative Approach was used for data collection and analysis and using the theory of Social Construction, the author explains how different contexts and aspects in the Zambian Society, that is Traditional, Socio-economic, Political, etc., influence the sexuality or sexual behavior of young people in Zambia. Hermeneutics was used to interpret the meanings in the texts/transcripts acquired through data collection and from the author?s knowledge and understanding of the Zambian historical and cultural contexts within which the participants of the research were constructed. Max Weber?s Ideal Type concept was also used to explain that each young individual?s sexual behavior is uniquely constructed by societal aspects.

Testrigg för marksensor

Lansen Technology is a security company from Halmstad, Sweden and their focus indeveloping and selling alarm solutions. One of their latest inventions is a vibration sensor thatrecognizes very small movements in the ground.The thesis work was made in cooperation with Lansen Technology AB and the task was toinvent a test equipment that decides whether the sensor is working correctly. By generatingcertain frequencies with specific amplitude, we will expect the sensor to give a similar output.The final report includes all the parts of our work as studying, choosing components,programming, construction, results and conclusion..

Topologioptimering av kölskydd för segelbåtar

I detta arbete har utformningen av ett kölskydd av metall för segelbåtar tagits fram. Kölskyddet som framtagits monteras längst ner på kölen. Syftet är att minska krafterna som verkar på båten vid en grundstötning genom att ta upp en del av rörelseenergin genom plastisk deformation.Vid utformningen av kölskyddets struktur har en metod för topologioptimering använts där målet varit att få så hög töjningsenergi (IED) i strukturen som möjligt. En heuristisk lösningsmetod där ineffektiva element tas bort ur strukturen har använts.Lämpliga material har undersökts och utvärderats utifrån mekaniska egenskaper samt motståndskraft mot korrosion i havsmiljö.Arbetet har resulterat i ett designförslag på en struktur av aluminium 5086 som enligt beräkningar kan absorbera 5 kJ energi. Detta motsvarar, för en båt som väger fyra ton, en minskning av energin som överförs till kölen på ca 10 %..

From conceptual drawings to produce components for this project have we together with a number of company take developed the right components for this project. We have calculated and analyzed the construction to get the best result for it purpose. Unfortunately have the process to produce the 3D milling has been stopped because of deficient budget and time.

Teknikkonsultföretags anpassning inför en kommande lågkonjunktur

This thesis work is about how technical consulting companies can accept their organization before a coming recession. Technical consulting companies are together with the rest of the actors in the construction business constantly depended on the current economic situation on the market. How to adapt the organisation depends on the current situation on the market.To adapt the organization in the best way possible the companies need to recruit and educate personal. It is then very important to find a solution on how the current change of generation in the companies will be handled. The large and very much competent group of 40-talists will in a few years retire.

This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.

Samverkan mellan nya cementtyper och tillsatsmedel för betongtillverkning

Cement manufacture accounts for 3-5 percent of total global carbon emissions. There is a growing interest in reducing the environmental impact and conserve limited natural resources. In cement production, clinker productions consume 87.5 percent of the total energy consumed in the cement manufacture.Cementa has since many years, focused on reducing the environmental impact of cement production. The work has involved the entire production process from selection of alternative fuels to the development of cement with less clinker content. During 2013/2014, two new types of cement (Bascement and CEM II / B) will be introduced to the Swedish market.

AbstractStudents at Mälardalen University have long performed their lab on a small turbojet engine in the course Aircraft Engine Technology. Since 2011, the engine has been dysfunctional. This was due to lack of maintenance. Since the lab has been an important element in teaching, the University had decided to get the engine functional again. This thesis project has been a request of Mälardalen University.The task we were assigned to was:1.

Integration av konstruktionsdatabas och styrsystem

The Mission at ÅF Industry in Norrkoping was about optimizing bulk data handling while importing process tag types from their construction database into the Process Controlled System of type Siemens PCS7.I found three different methods to solve the task. Two of them were using different software from Siemens under the premise that the report from the database was corrected as needed. The third variant was manually creating the circuits. All methods worked out fine but there were times when one was better than another.To solve this task I had access to all software presented in chapter 2 ?Programvara? (=Software).
