O mangá é uma das mídias mais relevantes do Japão. Ele figura parte significativa da cultura popular japonesa e, como produto de tal cultura, está intrinsecamente ligado aos aspectos que constituem a sociedade nipônica. Com sua linguagem híbrida (imagem e escrita), o mangá vem permeado de elementos socioculturais, cujas representações apresentam um mosaico da sociedade. Como uma imagem substituta, ele retrata práticas sociais e conceitos (valores) que permitem diferentes e várias leituras da sociedade e cultura japonesa. Nessas narrativas, o protagonista do mangá agirá como ator social, sendo, concomitantemente, produtor e testemunha das práticas socioculturais japonesas. Este trabalho tem como objeto de estudo o mangá One Piece de Oda Eiichiro (1975), cujo enredo narra as aventuras da tripulação Piratas do Chapéu de Palha, comandada por Monkey D. Luffy. Por meio do protagonista e herói da narrativa, Monkey D. Luffy, procurou-se identificar elementos que fazem referência a aspectos característicos da figura do herói, visto que esse se reveste com as características de maior valor e destaque de sua cultura de origem. Na análise constatou-se a representação e o praticar de valores como honra, autossacrifício, lealdade, esforço, disciplina, perseverança e sinceridade. Pelas interações do protagonista também pode se verificar a pratica de dinâmicas sociais como hierarquia social, o conceito de on (débito moral) e giri (dever moral), além de referências a aspectos culturais da yakuza (máfia japonesa). / Manga is one of the most relevant midia in Japan. It has a significant part of Japanese popular culture and, as a product of such culture, is intrinsically linked to aspects that constitute Japanese society. With its hybrid language (image and writing), manga is permeated by sociocultural elements, whose representations present a mosaic of society. As a surrogate image, manga depicts social practices and concepts (values) that allow different and various readings of Japanese society and culture. In these narratives, the protagonist of manga will behave as a social actor, being, at the same time, a producer and a witness of Japanese sociocultural practices. Therefore, the aim of this study is manga One Piece written by Oda Eiichiro (1975), whose story tells the adventures of Hat of Straws pirate crew, commanded by Monkey D. Luffy. Through the protagonist and hero of the narrative, Monkey D. Luffy, it was expected to identify elements that make reference to characteristic aspects of the hero, since this one is full of characteristics of greater value and highlight of his culture of origin. In the analysis, it was found the representation and practice of values like honor, self-sacrifice, loyalty, effort, discipline, perseverance and sincerity. Through the interactions of the protagonist can also be verified the practice of social dynamics such as social hierarchy, the concept of on (moral debt) and giri (moral duty), as well as references to cultural aspects of yakuza (Japanese mafia).

Subdivision surfaces are capable of modeling and representing complex shapes of arbi-trary topology. However, methods on how to build the control mesh of a complex surfaceare not studied much. Currently, most meshes of complicated objects come from trian-gulation and simplification of raster scanned data points, like the Stanford 3D ScanningRepository. This approach is costly and leads to very dense meshes.Subdivision surface based one-piece representation means to represent the final objectin a design process with only one subdivision surface, no matter how complicated theobject's topology or shape. Hence the number of parts in the final representation isalways one.In this dissertation we present necessary mathematical theories and geometric algo-rithms to support subdivision surface based one-piece representation. First, an explicitparametrization method is presented for exact evaluation of Catmull-Clark subdivisionsurfaces. Based on it, two approaches are proposed for constructing the one-piece rep-resentation of a given object with arbitrary topology. One approach is to construct theone-piece representation by using the interpolation technique. Interpolation is a naturalway to build models, but the fairness of the interpolating surface is a big concern inprevious methods. With similarity based interpolation technique, we can obtain bet-ter modeling results with less undesired artifacts and undulations. Another approachis through performing Boolean operations. Up to this point, accurate Boolean oper-ations over subdivision surfaces are not approached yet in the literature. We presenta robust and error controllable Boolean operation method which results in a one-piecerepresentation. Because one-piece representations resulting from the above two methodsare usually dense, error controllable simplification of one-piece representations is needed.Two methods are presented for this purpose: adaptive tessellation and multiresolutionanalysis. Both methods can significantly reduce the complexity of a one-piece represen-tation and while having accurate error estimation.A system that performs subdivision surface based one-piece representation was im-plemented and a lot of examples have been tested. All the examples show that our ap-proaches can obtain very good subdivision based one-piece representation results. Eventhough our methods are based on Catmull-Clark subdivision scheme, we believe they canbe adapted to other subdivision schemes as well with small modifications.

Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility. The functionality of the fabric and the form needed in urban lifestyle is explored in terms of relationship to a reduced, intuitive construction to challenge the norm of aesthetics in active sportswear. Meeting the demands of the conscious urban inhabitants regarding sustainability and style challenges this further. / Program: Modedesignutbildningen

Also there is an introduction of the company and its production portfolio. Crucial part of this thesis is it‘s practical part focused on improving of current situation on the production line with an economical and technical assessment. The main goal was to create more compact and smaller area of product line with lower work in progress.

This work deals with definition of garments. It explores how little changes a piece of fabric needs to still make it into a garment. What is it that defines a garment, is it just that something is done with a piece of fabric or does it need some recognizing of body parts. The aim is to find new ways of construction without using templates and questioning when textile becomes garments by draping and cutting.Through using how clothes are fitted to the body but instead of using pattern templates work from a rectangle and make it fit the body as garment. Working from two-dimensional to three-dimensional by the help of the body, going directly from fabric to garment. By defining the essential parts in every garment and cutting holes in a rectangle to highlight a certain body part or letting the body go trough different holes to make the fabric turn and drape around the body. Conclusion of the work is that a cut or incision doesn’t always define a garment, that it takes another recognition as well to make the definition. During the development questions have arise as for example how to construct holes in all fabrics and deal with the finishing, how to use raw edges without ripping, how to sew were there is no seam allowance and how to create fabric suited for cutting. / Program: Modedesignutbildningen

The subject of this diploma thesis is to improve the manufacturing of ISO standard valves using basic Lean manufacturing methods. Focus was at two levels, the macro level dealing with auxiliary processes for the whole manufacturing area and the micro level looking at removal of waste in the processes on one particular production cell.

Globalization and the increasing time to market have led to ever-higher requirements on the production systems. More than often the short-term thinking and the chase for profit lead to cheap quick fixes. The manufacturing industry changes slowly while the market is changing rapidly, which requires long-term planning for capacity increase but at the same time the ability to rapidly respond to changes. The most crucial factors determining the ability to efficiently produce and deliver a product to market is the utilized production system and a well stated manufacturing strategy. The choice of a certain production system depends on company conditions and requirements as well as the market demands. The current production systems performance and ability to handle different production volumes and divergence must be considered and evaluated from an economical perspective. During this thesis work the benefits and disadvantages with batch flow and one-piece flow have been examined. Generally one-piece flow had been considered the most efficient regarding performance and economical aspects. Meanwhile, batch flow had some benefits associated to it regarding high level of flexibility to handle several different product variants and better possibilities to govern the material flow compared to one-piece flow. There has also been examined which are the most crucial factors affecting the choice between one-piece flow and batch flow. It emerged during the thesis work that the most crucial factor affecting the choice of production system was the Manufacturing Strategy. It can be considered as the ground for every decision regarding the production system and future investments. It determines where the company currently stands, where they want to be in the future and which steps they need to take to get there. The economical factor is as least as important because all decisions include more or less costly investments. At the same time the chosen production system must be as efficient as possible and generate money for the company. Based on these two main factors other interesting factors have been presented. These factors may not affect the choice as much, but are to be considered as important in this context The most crucial factors found to affect the choice of a production system were; Manufacturing Strategy, Economical factors, Production planning and control, Flexibility and capacity, Production volume, variants and trends. The research work has been conducted over a twenty-week period, during which data collection has been performed via Multiple Case Studies at four companies manufacturing similar components within the light and heavy automotive industry. Additional data collection has been performed through a literature review by examining relevant material for the research questions. This have led to a collected knowledge base regarding benefits and disadvantages with each production system along with underlying reasons for deciding on one of them. Based on the collected material from the Case Studies and the theoretical findings, a Mind map visualizing the crucial factors affecting the choice of a production system is presented. This can be utilized by the companies in order for structured evaluation of their current production system and for planning for future changes within production. / Globaliseringen och den ökande pressen på företag att producera och få ut produkter på marknaden på kortast möjliga tid har lett till att det ställs allt högre krav på produktionssystemen. Allför ofta leder kortsiktigt tänkande och jakten på vinster till att företag väljer enkla och billiga snabblösningar. Tillverkningsindustrin förändras långsamt medans marknaden ändras fort, vilket kräver att företagen kan planera för långsiktiga kapacitetsökningar och ändå ha beredskap för att snabbt kunna anpassa sig till förändringar. Det som till allra största del avgör hur effektivt man kan producera och leverera en produkt till marknaden är vilket produktionssystem ett företag använder samt en välformulerad tillverkningsstrategi. Vilket produktionssystem man väljer är beroende av vilka förutsättningar och krav ett företag har lika mycket som av marknadskraven. Man måste ta hänsyn till det nuvarande produktionssystemets prestanda och möjlighet att hantera ändrade produktionsvolymer och variantflora och utvärdera detta ur en ekonomisk synvinkel. Under detta examensarbete har för- och nackdelar med batchflöde och enstycksflöde undersökts och utvärderats. Generellt sätt har enstycksflöde konstaterats vara mest effektivt rent ekonomiskt och prestandamässigt. Däremot, har batchflöde tilldelats fördelar som hög flexibilitet att hantera olika produktvarianter och bättre möjligheter att styra materialflödet jämfört med enstycksflöde. Det har även undersökts vilka som är de mest avgörande faktorerna som styr valet av enstycksflöde eller batchflöde. Under arbetets gång framkom det att den mest avgörande faktorn som påverkar valet av produktionssystem var företagets Produktionsstrategi. Den kan anses vara grunden för alla beslut rörande produktionssystemet och framtida satsningar. Där visar man var företaget befinner sig idag samt var man vill vara i framtiden och vilka beslut man måste ta för att ta sig dit. Den ekonomiska faktorn är minst lika viktig, då alla beslut i slutändan handlar om mer eller mindre kostsamma investeringar. Samtidigt måste det valda produktionssystemet vara så effektivt som möjligt och generera pengar till företaget. Med utgångspunkt från dessa två huvudfaktorer har andra intressanta faktorer tagits fram, som inte påverkar valet av produktionssystem i lika hög grad, men som ändå kan anses vara viktiga i sammanhanget. Forskningsarbetet har bedrivits under 20 veckors tid, där datainsamling har utförts via fallstudier på fyra företag som tillverkar liknande komponenter inom fordonsindustrin. Vidare datainsamling har gjorts genom en litteraturstudie där relevant material för forskningsfrågorna har undersökts. Detta har lett till en samlad kunskapsbas gällande för- och nackdelar med de respektive produktionssystemen samt bakomliggande orsaker till att välja något av dessa produktionssystem. Utifrån det samlade materialet från fallstudierna samt de teoretiska rönen har sedan en tankekarta tagits fram, som visualiserar de avgörande faktorerna som påverkar valet av ett produktionssystem. Denna tankekarta kan företag använda sig av för att på ett strukturerat sätt utvärdera nuvarande produktionssystemet samt planera för framtida förändringar inom produktionen.
