The area of this work is a combination of draping and printing. It strives towards the technique that dazzles the eye with illusions of more than one dimension. As a viewer you will believe that the prints are real drapings while they are flat surfaces. Today prints in fashion are categorized as placed prints or all-over prints, and generally created as a flat surface to decorate the garments. In this work the idea is to manipulate and challenge the boundaries of print and give it life through the body shapes and in the movement. Potentially this work could be an introduction to a new way of working with prints in fashion. This work could poosibly be presented as a new technique where placed- print and all-over prints comes together- called placed all-over prints. Also, it could develop into further techniques in using two-dimensional flatness and save fabric in using photography as an option to the real three-dimensional drapings. Furthermore could it mean savings in material as a conscious choice in the process ? This investigation explores two particular kinds of techniques, - print and draping, that are merged into one expression. The aims of this work is to find new ways of using print in combination with draping in dress and explore the possibilities to find a new technique to create interesting womenswear. To unite dimensions like two-dimensional and three-dimensional as a method of finding new forms and expressions. Through experiments with striped textiles the focus is to investigate the possibilities of greater visual effects on two-dimensional prints. For a depth and to exaggerate the directions in the fabric before translating it into a flat surface the striped textile can be a tool for further design. The striped textile has the potential to help the eye to understand the directions in the print and can be used in more than one dimension and color. To explore how to create 3D effect on 2D in print design through draping in dress is the aim of this work.Program: Modedesignutbildningen

Full textAbstract:
Biokomposit är ett material som har stor potential att ersätta plastprodukter i framtiden. Med ett innehåll av träfibrer och växtbaserad plast är det både biologiskt nedbrytbart och fullt möjligt att återvinna. I det här projektet undersöks materialet biokomposit i samklang med additiv tillverkning, 3D-print. Syftet är att undersöka materialets estetiska potential, och visa möjligheter inom en tillverkningsteknik som inte håller samma status som exempelvis formsprutning. Författaren vill framhäva det som många skulle se som defekter i en tillverkningsprocess, för att ge komplement till Studio Tabos rotationssymmetriska armaturer. En fokusgrupp har varit till stöd i beslutstagande, och processen har varit experimentell med strikta ramar och mål. Det intressanta är inte hur man kan skriva ut ett objekt, utan det är varför. Är det för massproduktion av kommersiella produkter som kräver perfektion, så är inte additiv tillverkning rätt väg att gå. Är det för att göra en mindre kollektion, i en produkt där tekniken estetiskt tillför någonting kan tekniken i stället vara en fördel. Framtiden ser ljus ut för nya produkter och det finns mer att utforska i ämnet.

Full textAbstract:
Modebranschen utvecklas kontinuerligt och är i stort behov av nya processer och tekniker för att kunna effektivisera produktutvecklingsfaserna för att fortsätta växa och lyckas. Denna uppsats grundar sig i problematiseringen om ökande problem inom modeindustrin som rör överproduktion, som i sin tur resulterar i långa ledtider, höga kostnader, miljöskada och osålda produkter. Uppsatsens syfte är att undersöka produktutvecklingsfaser inom modeföretag och undersöka hur de kan effektiviseras genom att implementera ny designteknik. Mer specifikt att införa 3D-designverktyg i produktutvecklingsprocessen. Uppsatsen använder sig av kvalitativa metoder som analys av olika teoretiska studier, utförande av fältstudier samt semi-strukturerade intervjuer. Den tidigare forskningen visar olika studier med fokus på 3D-designtekniker för att skapa en förståelse och grund. För att vidareutveckla uppsatsen utfördes intervjuer och observationer på modeföretag. Intervjuer och observationer bidrog med information kring skillnaden mellan företags användning av endast 2D-designtekniker och företag som infört 3D-designtekniker. Från all sammanställd information framkom att en implementering av 3D-designverktyg kan gynna företag i att bli mer tidseffektiva i sin produktutvecklingsprocess. Resultatet svarar på de utformade forskningsfrågorna samt väckte ett flertal frågor att studera i vidare forskning. Studien avgränsar sig till att analysera enbart tidsperspektivet, och kan då i vidare forskning analysera andra aspekter som ekonomi och miljö.The fashion industry is a continuously developing industry that is in great need of new processes and technologies to be able to streamline the product development phases in order to continue to grow and succeed. This thesis is based on the problematization of increasing problems in the fashion industry concerning overproduction, which in turn results in long lead times, high costs, environmental damage and unsold products. The purpose of the thesis is to investigate the product development phases in fashion companies and examine how they can be made more efficient by implementing new design technology. More specifically, introducing 3D design tools into the product development process. The thesis used qualitative methods such as analysis of various theoretical studies, execution of field studies and semi-structured interviews. The previous research shows various studies focusing on 3D design techniques to create an understanding and foundation. To further develop the paper, interviews and observations were carried out at fashion companies. The interviews and observations provided information about the difference between companies' use of only 2D design techniques and companies that introduced 3D design techniques. From all the compiled information it emerged that an implementation of 3D design tools can benefit companies in becoming more time-efficient in their product development process. The results responded to the research questions and raised several questions to study in further research. The study is limited to analyzing only the time perspective, and can then analyze other aspects such as economy and the environment in further research.

Full textAbstract:
In this report, my work on 3D-printing will be presented. This project is what constitutes my examination project in the education of industrial design engineering. 3D-printers are tools that have undergone great development in recent years. Through this development, the machines have become increasingly accessible to private individuals thanks to reduced prices, easyer use and higher quality. Through an increased use of the tool on a more private level, new opportunities are created for how we manufacture products, as well as how our attitude to its components are viewed. The purpose of the work was to investigate how 3D-printing can be used to create more efficient and sustainable products with a focus on users, manufacturers and the environment. The goal was to develop an approach to utilize the function of a 3D-printer in a way that contributes to higher sustainability and efficiency, where the end result should contribute to this without forcing the user to make any decisive sacrifices. The work has been carried out with a three-part process, divided into the phases Inspiration, Ideation and implementation, which together constitute an iterative design process. Initially in the inspiration phase, inspiration was created for the work with the help of a literature study, theory collection and a context analysis. Then began the ideation phase, whose purpose was to start creating ideas and conceptualize the inspiration that has previously been collected in the inspiration phase. To implement these ideas and concepts, the implementation phase was carried out to achieve a more completed and implemented concept. The work resulted in the concept TonePrint. TonePrint is a speaker and a pair of headphones that work together in a form of ecosystem to make the interaction smoother for the user when changing audio source. The product TonePrint is a product that the user 3D-prints by oneself. This contributes to a more efficient and sustainable product as well as production. The product is designed in a way that enables the user to configure the product based on their own needs, which contributes to increased personalization. It allows the user to reuse components from previous devices that would otherwise be discarded, or select components based on their own liking and taste.I den här rapporten kommer mitt arbete rörande 3D-printeing presenteras. Det här projektet är det som utgör mitt examensarbete i utbildningen högskoleingenjör inom teknisk design. 3D-printers är verktyg som har genomgått stor utveckling de senaste åren. Genom den här utvecklingen har maskinerna blivit allt mer tillgängliga för privatpersoner tack vare lägre priser, smidigare användning och högre kvalitet. Genom en ökad användning av verktyget på mer privata plan skapas nya möjligheter för hur vi tillverkar produkter, samt hur vi ser på produkter och dess uppbyggande komponenter. Syftet med arbetet var att undersöka hur 3D-printing kan användas för att skapa mer effektiva och hållbara produkter med fokus på användare, tillverkare och miljön. Målet var att ta fram ett tillvägagångssätt att nyttja de egenskaper en 3D-printer medför på ett sätt som bidrar till en högre hållbarhet och effektivitet, där det slutliga resultatet ska bidra till detta utan att tvinga användaren att göra några avgörande uppoffringar. Arbetet har genomförts med en tre delad process, indelad i faserna Inspiration, Ideation och implementation som tillsammans utgör en iterativ designprocess. Initialt i inspirationsfasen skapades inspiration för arbetet med hjälp av en litteraturstudie, teoriinsamling samt en kontextanalys. Därefter påbörjades ideationsfasen, vars syfte var att börja skapa idéer och konceptualisera den inspirationen som tidigare blivit insamlad i inspirationsfasen. För att implementera dessa idéer och koncept utfördes implementationsfasen för att nå ett mer färdigställt och förverkligat koncept. Arbetet resulterade i konceptet TonePrint. TonePrint är en högtalare och ett par hörlurar som samverkar i ett form av ekosystem för att göra interaktionen smidigare för användaren vid byte av ljudkälla. Produkten TonePrint är en produkt som användaren själv 3D-printar. Detta bidrar till en mer effektiv och hållbar produkt samt produktion. Produkten är utformad på ett sätt som möjliggör för användaren att konfigurera produkten utifrån eget behov vilket bidrar till en ökad personalisering. Det möjliggör för användaren att återanvända komponenter från tidigare enheter som annars skulle slängas, eller välja komponenter utifrån eget tycke och smak.

Full textAbstract:
Many architects report about mentally visualizing 3D aspects of their design ideas while simply working with 2D sketches of them. Indeed, in architecture, the general practice of conveying 3D building information by means of 2D drawings bears on the assumptions that every architect can mentally visualize a building in 3D by looking at its 2D drawings or sketches and that architects, as many report, can capture the 3D aspects of a building design during such 3D mental visualization practices. Additionally, many intuitively believe that the levels at which architects perform such 3D mental visualization practices is highly correlated to their spatial visualization abilities as defined by existing measures of spatial visualization ability. This thesis presents the outcomes of protocol studies and analyses that were conducted with the aim of developing an in-depth understanding about such 3D mental visualization practices and capabilities of architects on the basis of four research questions. First, what might be the nature of the 3D mental visualization phenomena that architects claim to experience: what are the features of these 3D mental visualizations as evidenced in specific tasks; and what might be the nature of the mental representations created during these visualization processes? Second, can every architect carry out these 3D mental visualization practices; might there be individual differences among architects' performances? Third, might 3D mental visualization of buildings be only an architectural skill; can non-architects, who can read 2D architectural drawings, visualize a building in 3D based on its 2D drawings and can they do so to the same levels of performance of those of architects? Fourth, might performance in 3D mental visualization tasks be related to/predicted by spatial visualization ability? The major conclusions of this thesis with regard to the first research question include that (1) architects can be visualizing the buildings in one of the two major forms or by alternatively switching between them: by imagining themselves situated within (almost) the actual size 3D building environment or by imagining a 3D small scale model of the building; (2) the mental representations they create during these visualization processes capture the various visual and spatial aspects of the buildings with a structure similar to that of an actual size or small scale model of the visualized space/form, yet the way they capture these aspects is not like the way these aspects would be captured from a certain viewpoint in reality; and (3) what they experience during these visualization processes is not like the continuous holistic visuospatial experience that one would have when looking at a building or walking inside/around a building. With regard to the second, third and fourth research questions this thesis concludes that (question 2) architects differ in their 3D mental visualization skills; (question 3) 3D mental visualization is an architectural skill in that it relies on certain abilities that become heightened in architects, possibly during education; and (question 4) 3D mental visualization skills are not related to spatial visualization ability as defined by the standard paper-folding test of spatial visualization ability.

Full textAbstract:
I samband med digitaliseringens intåg har nya förbättrade BIM-verktyg börjat användas för att effektivisera konstruktörens arbete. Med hjälp av implementering av grafiska tredjepartsprogram kan BIM verktygen bidra med ökat funktionalitet. Ett exempel på ett sådant program är tredjepartsprogrammet Grasshopper kopplat till BIM-verktygen Tekla Structures som skapar parameterstyrning, vilket innebär att modellens data styrs och nås av de externa programmen. På Rambolls Bro- och Tunnelavdelning vill man idag, som många andra konsultföretag bli mer BIMorienterade. Dock saknas en uppskattning av den totala tidsbesparingen och nyttjande av tredjepartsprogrammen. Syftet med detta examensarbete har varit att komma fram till en slutsats som ger stöd i beslutsfattande kring vilka typer av projekt som parameterstyrda modeller kan vara lämpliga för. Genom uppbyggnad av ett automatiserat skript för en stödmur har denna studie visat kopplingen mellan programvarorna Microsoft Excel, Rhinoceros-Grasshopper och Tekla Structures. Med denna tillämpning har man lyckats skapa ett lätthanterligt användargränssnitt. Vidare har man jämfört det färdiga skriptet i Grasshopper med en modellering i Civil 3D där man har kommit fram till att man kan vinna tid på att ha ett optimalt skript. Man har även kunnat dra slutsatser under vilka förhållanden det lämpar sig att använda parametrisk modellering och automatisering som pekar mot tidiga skeden i projektering och standardkonstruktioner.In connection with the digitalization's entry, the companies has begun to apply new improved BIMtools to streamline the constructor's work. With the help of the implementation of graphical thirdparty applications, the BIM-tools can achieve increased functionality. An example of such a program is the third party applications Grasshopper linked to the Tekla Structure, which creates so called computational design, which means that the model's data is controlled and accessed by the external programs. The Bridge and Tunnel department at Ramboll wants to become, like many other consulting firms, more BIM oriented. However, there is no estimate of total timesaving and utilization of the implementation today. The purpose of this thesis project has been to come at a conclusion that provides support in decision-making regarding which types of projects that parameter-controlled models may be suitable for. By building an automated script for a retaining wall, this study has shown the connection between the software Microsoft Excel, Rhinoceros-Grasshopper and Tekla Structures. With this application, one has succeeded in creating an easy-to-use interface. Furthermore, one has compared the finished script in Grasshopper with a model in Civil 3D where the assumption that one can gain time by having a finished script. It has also been possible to draw conclusions under which conditions it is suitable to use parametric modeling and automation that points to early stages in design and standard constructions.

Implement a high-level model of computationally intensive part of 3D graphics pipe-line. Increasing popularity of handheld devices along with developments in hardware technology, 3D graphics on mobile devices is fast becoming a reality. Graphics processing is essentially complex and computationally demanding. In order to achieve scene realism and perception of motion, identifying and accelerating bottle necks is crucial. This thesis is about Open-GL graphics pipe-line in general. Software which implements computationally intensive part of graphics pipe-line is built. In essence a rasterization unit that gets triangles with 2D screen, texture co-ordinates and color. Triangles go through scan conversion, texturing and a set of other per-fragment operations before getting displayed on screen.

Full textAbstract:
This work presents a novel, design-driven quadrangulating method for closed 3D
curves. While the quadrangulation of existing surfaces has been well studied for a
long time, there are few works that can successfully construct a quad-mesh relying
solely on 3D curves, as the shape of the surface interior is not uniquely defined.
I observe that, in most cases, viewers can complete the intended shape by envisioning
a dense network of smooth, gradually changing flow-lines across a pair of
input curve segments with similar orientation and shape. The method proposed
here mimics this behavior.
This algorithm begins by segmenting the input closed curves into pairs of
matching segments. I interpolate the input curves by a network of quadrilateral
cycles whose iso-lines define the desired flow line network. I proceed to interpolate
these networks with all-quad meshes that convey designer intents. I evaluate
my results by showing convincing quadrangulations of complex and diverse curve
networks with concave, non-planar cycles, and validate my approach by comparing
my results to artist generated interpolating meshes.
My algorithm is suitable for use in sketch-based modeling systems as well as
in other applications where artist curves can be created.

CMOS image sensor based on Active pixel sensor has considerably contributed to the imaging market and research interest in the past decade. Furthermore technology advancement has provided the capability to integrate more and more functionality into a single chip in multiple layers leading to a new paradigm, 3D integration. CMOS image sensor is one such application which could utilize the capability of 3D stacked architecture to achieve dedicated technologies in different layers, wire length reduction, less area, improved performancesThis research work is focused mainly on the early stages of design space exploration using hierarchical approach and aims at reducing time to market. This work investigates the imager from the top-down design perspective. Methodical anal y sis of imager is performed to achieve high level of flexibility and modularity. Re-useable models are developed to explore early design choices throughout the hierarchy. Finally, pareto front (providing trade off solutions) methodology is applied to explore the operating range of individual block at system level to help the designer making his design choice. Furthermore the thermal issues which get aggravated in the 3D stacked chip on the performance of the imager are studied. Systeme based thermal model is built to investigate the behavior of imager pixel matrix and to simulate the pixel matrix at high speed with acceptable accuracy compared to electrical simulations. The modular nature of the model makes simulations with future matrix extension straightforward. Validation of the thermal model with respect to electrical simulations is discussed. Finally an integrated design flow is developed to perform 3D floorplanning and to perform thermal anal y sis of the imager pixel matrix.

Full textAbstract:
The objective of this research is to develop physical design methodologies for monolithic 3D ICs and use them to evaluate the improvements in the power-performance envelope offered over 2D ICs. In addition, design-for-test (DfT) techniques essential for the adoption of shorter term through-silicon-via (TSV) based 3D ICs are explored.
Testing of TSV-based 3D ICs is one of the last challenges facing their commercialization. First, a pre-bond testable 3D scan chain construction technique is developed. Next, a transition-delay-fault test architecture is presented, along with a study on how to mitigate IR-drop. Finally, to facilitate partitioning, a quick and accurate framework for test-TSV estimation is developed.
Block-level monolithic 3D ICs will be the first to emerge, as significant IP can be reused. However, no physical design flows exist, and hence a monolithic 3D floorplanning framework is developed. Next, inter-tier performance differences that arise due to the not yet mature fabrication process are investigated and modeled. Finally, an inter-tier performance-difference aware floorplanner is presented, and it is demonstrated that high quality 3D floorplans are achievable even under these inter-tier differences.
Monolithic 3D offers sufficient integration density to place individual gates in three dimensions and connect them together. However, no tools or techniques exist that can take advantage of the high integration density offered. Therefore, a gate-level framework that leverages existing 2D ICs tools is presented. This framework also provides congestion modeling and produces results that minimize routing congestion. Next, this framework is extended to commercial 2D IC tools, so that steps such as timing optimization and clock tree synthesis can be applied. Finally, a voltage-drop-aware partitioning technique is presented that can alleviate IR-drop issues, without any impact on the performance or maximum operating temperature of the chip.

3D Computer graphics is becoming an almost ubiquitous part of the world in which we live. being present in art. entertainment. advertising. CAD. training and education. scientific visualisation and with the growth of the internet. in e-commerce and communication. This thesis encompasses two areas of study: The design of algorithms for high quality. real-time 3D computer graphics rendering hardware and the methodology and means for achieving this. When investigating new algorithms and their implementation in hardware. it is important to have a thorough understanding of their operation. both individually and in the context of an entire architecture. It is helpful to be able to model different algorithmic variations rapidly and experiment with them interchangeably. This thesis begins with a description of software based modelling techniques for the rapid investigation of algorithms for 3D computer graphics within the context of a C++ prototyping environment. Recent tremendous increases in the rendering performance of graphics hardware have been shadowed by corresponding advancements in the accuracy of the algorithms accelerated. Significantly. these improvements have led to a decline in tolerance towards rendering artefacts. Algorithms for the effective and efficient implementation of high quality texture filtering and edge antialiasing form the focus of the algorithm research described in this thesis. Alternative algorithms for real-time texture filtering are presented in terms of their computational cost and performance. culminating in the design of a low cost implementation for higher quality anisotropic texture filtering. Algorithms for edge antialiasing are reviewed. with the emphasis placed upon area sampling solutions. A modified A-buffer algorithm is presented that uses novel techniques to provide: efficient fragment storage; support for multiple intersecting transparent surfaces; and improved filtering quality through an extendable and weighted filter support from a single highly optimised lookup table.

L'impact des interconnections d'un circuit intégré sur les performances et la consommation est de plus en plus important à partir du nœud CMOS 28 nm et au-delà, ayant pour effet de minimiser de plus ne plus la loi de Moore. Cela a motivé l'intérêt des technologies d'empilement 3D pour réduire l'effet des interconnections sur les performances des circuits. Les technologies d'empilement 3D varient suivant différents procédés de fabrication d'où l'on mettra en avant la technologie Trough Silicon Via (TSV) – Collage Cuivre-Cuivre (Cu-Cu) et 3D Monolithique. TSV et Cu-Cu présentent des diamètres d'interconnexions 3D de l'ordre de 10 µm tandis que le diamètre d'une interconnexion 3D Monolithique est 0.1 µm, c'est-à-dire cent fois plus petit. Un tel diamètre d'interconnexion créée de nouveaux challenge en terme de conception de circuit intégré numérique. Dans ce contexte, notre objectif est de proposer des méthodologies de conception de circuits 3D innovantes afin d'utiliser au mieux la densité d'intégration possible et d'évaluer efficacement les gains en performance, surface et consommation potentiels de ces différentes technologies d'empilement par rapport à la conception de circuit 2D.Trois contributions principales constituent cette thèse : La densité d'intégration offerte par les technologies d'empilement étudiées laisse le possibilité de revoir la topologie des cellules de bases en les concevant directement en 3D. C'est ce qui a été fait dans l'approche Cellule sur Buffer (Cell-on-Buffer – CoB), en empilant la fonction logique de base d'une cellule sur l'étage d'amplification. Les simulations montrent des gains substantiels par rapport aux circuits 2D. On a imaginé par la suite désaligner les niveaux d'alimentation de chaque tranche afin de créer une technique de Multi-VDD adaptée à l'empilement 3D pour réduire encore plus la consommation des circuits 3D.Dans un deuxième temps, le partitionnement grain fin des cellules a été étudié. En effet au niveau VLSI, quand on conçoit un circuit de plusieurs milliers voir million de cellules standard en 3D, se pose la question de l'attribution de telle ou telle cellule sur la tranche haute ou basse du circuit 3D afin d'accroitre au mieux les performances et consommation du circuit 3D. Une méthodologie de partitionnement physique est introduite pour cela.Enfin un environnement d'évaluation des performances et consommation des technologies 3D est présenté avec pour objectif de rapidement tester les gains possibles de telle ou telle technologie 3D tout en donnant des directives quant à l'impact des certains paramètres technologiques 3D sur les performances et consommationScaling limitations of advanced technology nodes are increasing and the BEOL parasitics are becoming more dominant. This has led to an increasing interest in 3D technologies to overcome such limitations and to continue the scaling predicted by Moore's Law. 3D technologies vary according to the fabrication process which creates a wide spectrum of technologies including Through-Silicon-VIA (TSV), Copper-to-Copper (CuCu) and Monolithic 3D (M3D). TSV and CuCu provide 3D contacts of pitch around 5-10um while M3D scales down 3D via pitch extremely to 0.11um. Such high-density capability of Monolithic 3D technology creates new design paradigms. In this context, our objective is to propose innovative design methodologies to well utilize M3D technology and introduce a technology assessment framework to evaluate different M3D technology parameters from design perspective.This thesis can be divided into three main contributions. As creating 3D standard cells become achievable thanks to M3D technology, a new 3D standard cell approach has been introduced which we call it ‘3D Cell-on-Buffer' (3DCoB). 3DCoB cells are created by splitting 2D cells into functioning gates and driving buffers stacked over each other. The simulation results show gain in timing performances compared to 2D. By applying an additionally Multi-VDD low-power approach, iso-performance power gain has been achieved. Afterwards cell-on-cell design approach has been explored where a partitioning methodology is needed to distribute cells between different tiers, i.e. determine which cell is placed on which tier. A physical-aware partitioning methodology has been introduced which improves power-performance-area results comparing to the state-of-the-art partitioning techniques. Finally a full high-density 3D technology assessment study is presented to explore the trade-offs between different 3D technologies, block complexities and partitioning methodologies

Rapid prototyping (RP) can be used to make complex shapes with very little or even no constraint on the form of the parts. New design methods are needed for parts that can take advantage of the unique capabilities of RP. Although current synthesis methods can successfully solve simple design problems, practical applications with thousands to millions elements are prohibitive to generate solution for.
Two factors are considered. One is the number of design variables; the other is the optimization method. To reduce the number of design variables, parametric approach is introduced. Control diameters are used to control all strut size across the entire structure by utilizing a concept similar to control vertices and Bezier surface. This operation allows the number of design variables to change from the number of elements to a small set of coefficients.
In lattice structure design, global optimization methods are popular and widely used. These methods use heuristic strategies to search the design space and thus perform, as oppose to traditional mathematical programming (MP) methods, a better global search. This work propose that although traditional MP methods find local optimum near starting point, given a quick convergence rate, it will be more efficient to perform such method multiple times to integrate global search than using a global optimization method. Particle Swarm Optimization and Levenburg-Marquardt are chosen to perform the experiments.

Full textAbstract:
Supercapacitors, also known as electrochemical capacitors, have shown great potential as energy storage devices; and 3D printing likewise as a manufacturing technique. This research progressively investigates combining these two technologies to fabricate 3D-printed, electrochemical double-layer capacitors (EDLCs). Small EDLCs were designed in a sandwich structure with an FDM-printed plastic frame and carbon electrodes. Inkjet printing was initially combined with FDM printing to produce a pilot sample with a silver ink current collector, however this performed poorly (Cs = 6 mF/g). Henceforth a paste extrusion system was added to the FDM printer to deposit the current collectors and electrodes, fabricating the entire device in a single continuous process. This process was progressively developed and tested, ultimately attaining specific capacitances of 200 mF/g. The fully integrated 3D printing process used to manufacture the EDLCs was a novel approach. Combining the FDM printer with a paste extruder allowed for a high degree of dimensional accuracy, as well as simplifying the production process. This aspect of the design functioned successfully, without significant faults, and proved a reliable fabrication method. The later designs used in this study provided the EDLCs extendable by incorporating connection jacks. This was to create the possibility to increase capacitance simply by connecting multiple EDLCs together. Tests of this feature showed that it worked well, with the extendable EDLCs delivering outputs very close to the theoretical maximum efficiency of the unit. Carbon conductive paint was applied as a current collector and electrode for the 3D printed EDLCs in an exploration of metal-free 3D printed supercapacitors. These metal-free EDLCs were found to provide around 60% of the specific capacitance of the best performing EDLC variant produced (silver paint current collectors with activated carbon and carbon paint mixture electrodes). Although considerable improvement is required to produce EDLC samples with comparable capacitances to existing commercial manufacturing techniques, this study lays important groundwork in this area, and has introduces effective and innovative design ideas for supercapacitors and integrated 3D printing processes.

Over the past decade, substantial effort has been directed toward developing ultrasonic systems for medical imaging. With advances in computational power, previously theorized scanning methods such as ultrasound tomography can now be realized. This thesis presents the design, error analysis, and initial image reconstructions from a single element 3D ultrasound tomography system. The system enables volumetric pulse echo or transmission imaging of distal limbs, for applications including: improving prosthetic fittings, monitoring bone density, and characterizing muscle health. The system is designed as a flexible mechanical platform for iterative development of algorithms targeting imaging of soft tissue with bone. The mechanical system independently controls movement of two single element ultrasound transducers in a cylindrical water tank. Each transducer can independently circle about the center of the tank as well as move vertically in depth. High resolution positioning feedback (~1[mu]m) and control enables flexible positioning of the transmitter and the receiver around the cylindrical tank; exchangeable transducers enable algorithm testing with varying transducer frequencies and beam geometries. High speed data acquisition (DAQ) through a dedicated National Instrument PXI setup streams digitized data directly to the host PC. System positioning error has been quantified and is within limits for the desired imaging modality. Imaging of various objects including: calibration objects, phantoms, bone, animal tissue, and human forearm are presented accordingly.

Full textAbstract:
3D bioprinting is the additive manufacture of biological materials, such as cells, and has been implemented over the last two decades to print 3D constructs which can mature into functional tissues. Although there are many bioprinting techniques, there are few that are capable of simultaneously printing two or more cell types at high resolutions, high cell densities and high initial cell viabilities. These printing characteristics are required to pattern cells in tissue-like micro-architectures and to quickly mature physiologically relevant tissue. We developed a novel 3D bioprinter and bioprinting methodology, designed to pattern cells without compromising these printing characteristics. Initially a droplet-in-oil 3D printer was created, which assembled mm-scale aqueous droplet networks composed of thousands of picolitre volume micro-compartments. These networks were programmed to show emergent tissue-like properties, mimicking nervous tissue's rapid electrical communication or self-folding in a manner similar to muscle contractions. This printing process was then adapted to pattern HEK-293T cells within droplet networks at high droplet resolution (~50-150 μm), high initial cell viability (90±4%) and high droplet cell density (~30x106 cells/mL). Capillary-like and layered sheet cell architectures were formed with two printed fluorescent cell populations. These 3D printed constructs were transferred to culture medium with minimal loss in pattern fidelity using a novel phase transfer approach. Patterned HEK-293T cells developed into dense cell organisations which showed, high cell viabilities, high cell numbers (up to ~18,000) and mitotically active cells, when cultured over 7 days. Specialised tissues were also developed, here, patterned ovine mesenchymal stem cells were differentiated, after printing, into chondrogenic progenitor cells as affirmed by Sox9 expression.

Full textAbstract:
With the ever increasing complexity of software systems programmers face new challenges in comprehending the structures of these programs, their artefacts, and the behavioural relationships among these artefacts. While modeling languages and notations that were introduced to support the forward engineering process have been quite effective in abstracting the underlying information, these techniques have failed when applied in a reverse engineering context. One reason for the failure is the information overload due to the level of detail available at the source code and a lack of appropriate filtering and analysis techniques. Another limitation of the current approaches is the conceptual gap that exists between the models created during the forward and reverse engineering process. This occurs because the reverse engineered model cannot convey the information and justification behind the architecture chosen. This gap is particularly noticeable when one considers the differences in layout, grouping and organization between the original and reverse engineered models. This thesis attempts to addresses these issues, by introducing a 3D extension of UML (Unified Modelling Language) diagrams to support the visualization of recovered design patterns from source code. The goal is to provide additional guidance during program comprehension. In addition, new viewing techniques are proposed to facilitate the navigation and filtering of the information in the three dimensional world

In the thesis, we have developed a computer aided design web system “WebCAD”. Users only needs a computer online and a web browser to use this system. This system provides functions of importing/exporting OBJ files of geometry definition, drawing computer graphics on web browser and uploading graphic models to remote database server. We use java programming language and JOGL package for WebCAD development. JOGL package is essentially the OpenGL API especially used for java programming language. Users can interactively operate graphic models using mouse wheel to zoom in/zoom out it, mouse left button to translate it and mouse right button to rotate it. WebCAD also provides some simple functions to edit graphic models. Due to large size of OBJ file, we define a special data structure to improve WebCAD efficiency of data transfer through Internet and graphic demonstration on client computer. Such a data structure packages all graphic model data into a data object. The data object is not only what remote database records but also what WebCAD stores in client computer memory. WebCAD also snapshots new model and upload it to remote web server and uses these snapshots to list user’s uploaded graphic models for easy management. WebCAD can export snapshot of graphic models to image files and save/open data object files. Finally, we test WebCAD efficiency and the results are satisfying.

Mobile games and mobile gaming platform have grown rapidly over the past five years, and the trend of mobile devices which become smaller and more powerful is likely to continue to develop; however, developing games for different mobile devices is never an easy task, especially for independent developers and amateur hobbyists. Different mobile platforms have their own developmental environments and APIs. It is fortunate that solutions do exist, such as Shiva3D, Unity3D, and so on. These developmental environments allow developers to take full advantage of a tool, and publish to different mobile devices. This research focuses on exploring the use of the developmental ShiVa3D engine, even if it is not very familiar to a developer, which can still be easily used to quickly develop simple games. In the past, developing a game often requires a big team, but now only a programmer, an artist, and a planner will be able to develop a game themselves. This is a solution for studios or independent developers that can save a lot of costs and time.

Due to the potential uses and advantages of 3D microelectromechanical systems
(MEMS), research has been ongoing to advance the field. The intention of my
reasearch is to explore different gripper designs and their interaction with corresponding
components to establish a 3D microassembly system. In order to meet
these goals, two grippers were designed using different mechanisms for grasping.
At the same time, corresponding parts capable of being constructed into a 3D microstructure
were designed to interact with the grippers. The microcomponents
were fabricated using PolyMUMPS, a part of the Multi-User MEMS Processes
(MUMPS), and experimentation was conducted with the goal of constructing a
3D microstructure. The results were partially successful in that both grippers were
able to pick up corresonponding parts and bring them out of plane in order to make
them stand up. However, a final 3D microstructure was unfortunately not achieved
due to time constraints. This will be left to future researchers who continue the
project.
On the equpiment side a microassembly system was fully integrated using cameras
for vision and motors with micro-resolution for movement. A computer program
was used to control each part of the system. The cameras provided feedback
from various views, allowing the operator to observe what was happening to the microcomponents.
The grippers were attached to one of the motors and manipulated
to pick up the parts. The final overall system proved sufficient for microassembly,
but had some areas that could be improved upon.

É cada vez mais raro apresentar-se um grande projeto, nas mais diversas áreas, em que não sejam colocadas imagens que permitam perceber o aspeto final da obra. Este documento foca-se na criação de imagens fotorrealistas, traduzindo o trabalho desenvolvido na empresa 1Plano, um estúdio focado na produção de catálogos, fotografias de produto e produção de imagens 3D. O primeiro passo para criar este tipo de imagem tem sempre por base uma pesquisa em áreas tão distintas quanto a fotografia, a propagação da luz, a computação gráfica e a álgebra. Esta pesquisa fornecerá, e forneceu neste caso, um suporte vital ao desenvolvimento de todos os projetos enquanto designer 3D. A maioria dos projetos desenvolvidos pela 1Plano relacionam-se com design de interiores e mobiliário, sendo desenvolvidos em software CAD com base em esboços fornecidos por designers e fotógrafos. Este tipo de imagens é utilizado em catálogos de produtos, websites das empresas e redes sociais. Também se encontram descritas as várias etapas de desenvolvimento de cada tipo de projeto, desde os esboços até ao resultado final.

With the increasing quality of CGI provided by the last advancements in computer graphics, a new market for high resolution render´s has emerged. Nowadays photorealistic visualization of computer generated models is a common sight. It's hard to find a big project, of any kind, which people can't see images of the final result. The focus of this document consists in the creation of photorealistic computer generated imagery, documenting the work developed in the company 1Plano, a studio focused on photography, catalogue design and 3D image production. The first step in order create this type of images always consists on research about several distinct areas, such as photography, light behavior, computer graphics and algebra. This research provides a vital theoretical support to all developed projects, as an intern 3D designer. Most of the projects where related with interior and furniture design, modeled and textured in CAD software, accordingly to sketches provided by interior designers and photographers. This synthetic images are used in product catalogue, company websites and social media. A detailed description of each type of project is also provided, from the designers sketches to final production. In this document it can be noticed the importance of this kind of visualization’s, trough senior 3D artists opinions and the author’s own work experience as intern.
