Föslag till Estetisk Mångfald

I chose to do this work because I believe that today?s industrial designprofessionals lack in their task of creating aesthetic experiences and aestheticdiversity.With my work, I want to question why the majority of today?s technical, massproducedeveryday products have such a similar design expression, andwhy alternatives are so few. Most of all, I take a critical attitude to today?sstereotypical industrial design aesthetics that I would describe as technical,masculine, and unnecessarily complex.I have designed a number of products that show alternative aesthetics in thissegment and as such I have chosen the vacuum cleaner. The idea is that mydesign will serve as an eye opener and demonstrate that there are alternativesto today?s homogeneous market.The result is three vacuum cleaners claiming three alternatives to currentofferings.

VAC-behandling på öppna bukar - En enkätstudie som belyser för- och nackdelar med behandlingen i omvårdnadssituationer

Vacuum-Assisted Closure (VAC)-terapi är en omläggningsmetod som används alltmer på alla typer av sår. Behandlingen stimulerar sårläkningsprocessen genom ett negativt tryck som suger ut överflödig sårvätska och minskar infektionsrisken. Syftet med studien var att belysa för- och nackdelar med VAC-behandling på patienter med öppna bukar i samband med omvårdnadssituationer utifrån sjuksköterskors och undersköterskors uppfattning. En empirisk enkätstudie gjordes med kvalitativ ansats. Manifest innehållsanalys användes som metod för att analysera resultatet.

Läcksökning med penetrant ? kvalitetssäkring av

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Kinas säkerhet : en studie av hur Kina hanterar regionala utmaningar

Kinas säkerhet - En studie av hur Kina hanterar regionala utmaningarDen regionala stabiliteten i Sydostasien präglas av Kinas tydliga dominans. Kinas strävan att bibehålla regional stabilitet kännetecknar den kinesiska utrikes- och säkerhetspolitiken. För Kina är ett stabilt närområde en viktig grundpelare i sin strävan mot att fortsätta sin ekonomiska tillväxt och öka sitt regionala och på sikt även globala inflytande. Ett stabilt närområde är dessutom en förutsättning för att Kina ska kunna öka sitt engagemang i områden bortom sitt närområde.Denna uppsats analyserar Kinas syn på sin säkerhet i sitt närområde, och hur denna uppnås och bibehålls. Genom en jämförande studie där Burma och Nordkorea tjänar som tämligen olika referensstater används ett realistiskt teoretiskt perspektiv för att förklara Kinas ageranden och val av strategi.Resultatet visar ett Kina som tydligt strävar efter att påverka sin omgivning på ett sätt som säkerställer säkerhet och ekonomisk tillväxt.

Omkonstruktion av treaxlig plockrobot och dess plockverktyg

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Definition av stötdämpares fyllnadsgrad

Shock absorber units play a key role in establishing the driving dynamics and performance of automobiles. Öhlins Racing has manufactured high-tech automotive shock absorbers for over 30 years. Öhlins Racing?s advanced technology has contributed to over 200 world championships in automobile racing. Öhlin?s manufacturing process has long utilized automated fluid filling equipment during the final shock absorber unit assembly stage. The filling process consists of vacuum pumping the shock absorber unit and subsequent transfer of fluid. Vacuum pumping is necessary to remove residual air from the shock absorber unit prior to initiating the liquid filling stage. The presence of undesirable gases drastically compromises the performance of a shock absorber. The filling degree, defined as the final ratio of air to oil, is determined by the specific filling protocol as well as the specific equipment utilized.The current investigation aims to develop a viable technique to accurately determine residual air content in shock absorber units. If the filling degree can be appropriately quantified for a specific manufacturing process, then the air/oil ratio may be quantitatively related to shock absorber performance. The utilized measurement method must be completely integrated into the manufacturing process to guarantee shock absorber performance specifications according to the manufacturer?s standards. By utilizing the measurement method developed in this work, the manufacturing process, manufacturing equipment and product specifications can all be tailored to provide improved filling conditions.The developed measurement method provides accurate quantification of the filling degree under a wide range of processing conditions. The method establishes the relative quantity of air in the shock absorber unit by performing in-situ compressibility tests. The fill ratio can be controlled and varied by manipulating the vacuum pressure exerted during the filling process. Performance tests, however, indicate no correlation between filling degree and unit performance..

EU:s gemensamma utrikes- och säkerhetspolitik - En studie om dess uppkomst och institutionella utformning

This thesis aims to explain the emergence of the Common Foreign and Security Policy of the European Union, and its institutional shaping, by using elements of Neofunctionalism and Liberal Intergovernmentalism.Using Neofunctionalism, the Common Foreign and Security Policy can be explained both as a side-effect of Europe's economic integration, and as a way to maintain the former and the European Union's position as an economic superpower. The institutional shaping is a result of lack of convergence between important national interests. Therefore it rests on a firm intergovernmental base, with rigorously limited use of supranational decision-making.For Liberal Intergovernmentalism, geopolitics and ideology, and to a certain level log-rolling, have played important roles. The reunification of Germany convinced France to form an alliance between the two countries. France, determined to achieve an economic and monetary union, thus offered Germany a political union, including a Common Foreign and Security Policy on intergovernmental terms.

Folkbiblioteken och informationsuppgiften: Fyra biblioteksorganisationers syn på folkbibliotek, folkbibliotekens bestånd samt deras roll i samhället.

The purpose of this paper is to examine different attitudes regarding freedom of information and how libraries should fulfil their information-task represented by four organisations. The organisations are important in shaping the Swedish public libraries in different ways. The purpose is to examine in what ways their definition of information freedom may differ from one another and what that means in defining the public library. For the survey the qualitative textual analysis has been used for examining the documents and websites that are part of the debate about the public library and information freedom. We chose to interview representatives of four organisations that in different ways influence the shaping of the public library.

Demokrati är demokraternas diktatur - en studie över den ryska politiska kulturen

I have investigated the political culture of post-communist Russia. For a long time it has been assumed that, the history is of great importance in shaping the political culture. I wanted to find out if this was true, I chose to study the political culture of Russia. How great effects had the autocratically legacy of Soviet Union in the democratisation of Russia? My thesis show that the role of history isn't of such great importance, instead it's the Russian state that has had the greatest possibility of shaping the political culture of Russia but it failed.

Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål

This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Det är inte så enkelt : Om talarens relation till publiken

???In this thesis I discuss the adaption of the speaker to the audience, and suggest a radical re-imagining of both the act of adaption and the reasons why adaption is necessary. My main purpose is to introduce social complexity into what I see as the pivotal point of both classic and modernrhetoric and thereby create new possibilities for future research.I accomplish this by modifying the rhetorical concept of doxa, moving from Pierre Bourdieu's separation of doxa and habitus ? the incorporated form of shared beliefs and values ? to an integrated view based in Manuel DeLanda's use of Gilles Deleuze & Félix Guattari's concept of the assemblage. In this way I formulate a notion of doxa that emerges from social interaction while at the same time shaping and regulating it.
