“Wearable Metal Origami”? The Design and Manufacture of Metallised Folding Textiles

“Wearable Metal Origami” is a research leading to a collection of wearable objects, made from metallised folding textile. The research engages with current concerns in industrialised society, where new materials and innovative products are in demand. The material I have developed is influenced by historical and contemporary jewellery and clothing as well as by deployable structures; folding patterns are based on folding patterns in nature and on the knowledge of origami mathematicians; production processes include traditional printing and jewellery techniques. Bridging all these disciplines, the outcome is a novel material that could be used in various design fields but is particularly relevant to jewellery for its striking visual character, its flexible movement which easily adjusts to the human body, and the possibility to use precious metals. I based my research in the department of Goldsmithing, Silversmithing, Metalwork and Jewellery because this department had helped me develop the initial material during my MA course, so I knew it could provide me with the necessary equipment and support in designing wearable pieces. My project was finally conducted within a departmental team research project (Deployable Adaptive Structures) in which my colleagues investigated the broader application of metallised or otherwise tessellated folded textile in such fields as interior architecture, sunscreens and water sculptures, and ways of actuating the material either virtually or by mechanical means. ““Wearable Metal Origami”?” is based on MA project work, where I had used one folding pattern and found one production method. I strongly believed that this material would be ideal for the creation of jewellery and larger wearable objects if I could expand the range of flexibly moving patterns, improve the production process of the material and develop appropriate design processes. My research set out to fulfil these requirements and prove the value of the material in the context of metalwork and jewellery and the applied arts. To expand the range of folding patterns I collected and analysed existing tessellating origami patterns. With this knowledge I created my own variations. All patterns were evaluated on their suitability for “Wearable Metal Origami” and a basic classification was made, based on their folding properties. A small selection of patterns was then tested to get an understanding of the influence of plate thickness, hinge width and hinge flexibility by making card-textile and plywood-textile models. I developed and tested new processes for the production of the metallised folding textile. These included preparatory processes (before electroforming), electroforming and various ways of treating the material after electroforming. Each process was evaluated on its practicality. To develop appropriate design processes for wearable objects of Metallised Folding Textile I ran four case studies, each with its own design brief. I set the briefs in such a way that they addressed different parts of the body and different qualities of the material, such as changing shape and flexibility. For each application an origami pattern was chosen and adjusted through a process of trial and error until it had the correct proportions and movement

Abstracting Multidimensional Concepts for Multilevel Decision Making in Multirobot Systems

Multirobot control architectures often require robotic tasks to be well defined before allocation. In complex missions, it is often difficult to decompose an objective into a set of well defined tasks; human operators generate a simplified representation based on experience and estimation. The result is a set of robot roles, which are not best suited to accomplishing those objectives. This thesis presents an alternative approach to generating multirobot control algorithms using task abstraction. By carefully analysing data recorded from similar systems a multidimensional and multilevel representation of the mission can be abstracted, which can be subsequently converted into a robotic controller. This work, which focuses on the control of a team of robots to play the complex game of football, is divided into three sections: In the first section we investigate the use of spatial structures in team games. Experimental results show that cooperative teams beat groups of individuals when competing for space and that controlling space is important in the game of robot football. In the second section, we generate a multilevel representation of robot football based on spatial structures measured in recorded matches. By differentiating between spatial configurations appearing in desirable and undesirable situations, we can abstract a strategy composed of the more desirable structures. In the third section, five partial strategies are generated, based on the abstracted structures, and a suitable controller is devised. A set of experiments shows the success of the method in reproducing those key structures in a multirobot system. Finally, we compile our methods into a formal architecture for task abstraction and control. The thesis concludes that generating multirobot control algorithms using task abstraction is appropriate for problems which are complex, weakly-defined, multilevel, dynamic, competitive, unpredictable, and which display emergent properties

Schematics of Graphs and Hypergraphs

Graphenzeichnen als ein Teilgebiet der Informatik befasst sich mit dem Ziel Graphen oder deren Verallgemeinerung Hypergraphen geometrisch zu realisieren. Beschränkt man sich dabei auf visuelles Hervorheben von wesentlichen Informationen in Zeichenmodellen, spricht man von Schemata. Hauptinstrumente sind Konstruktionsalgorithmen und Charakterisierungen von Graphenklassen, die für die Konstruktion geeignet sind. In dieser Arbeit werden Schemata für Graphen und Hypergraphen formalisiert und mit den genannten Instrumenten untersucht. In der Dissertation wird zunächst das „partial edge drawing“ (kurz: PED) Modell für Graphen (bezüglich gradliniger Zeichnung) untersucht. Dabei wird um Kreuzungen im Zentrum der Kante visuell zu eliminieren jede Kante durch ein kreuzungsfreies Teilstück (= Stummel) am Start- und am Zielknoten ersetzt. Als Standard hat sich eine PED-Variante etabliert, in der das Längenverhältnis zwischen Stummel und Kante genau 1⁄4 ist (kurz: 1⁄4-SHPED). Für 1⁄4-SHPEDs werden Konstruktionsalgorithmen, Klassifizierung, Implementierung und Evaluation präsentiert. Außerdem werden PED-Varianten mit festen Knotenpositionen und auf Basis orthogonaler Zeichnungen erforscht. Danach wird das BUS Modell für Hypergraphen untersucht, in welchem Hyperkanten durch fette horizontale oder vertikale – als BUS bezeichnete – Segmente repräsentiert werden. Dazu wird eine vollständige Charakterisierung von planaren Inzidenzgraphen von Hypergraphen angegeben, die eine planare Zeichnung im BUS Modell besitzen, und diverse planare BUS-Varianten mit festen Knotenpositionen werden diskutiert. Zum Schluss wird erstmals eine Punktmenge von subquadratischer Größe angegeben, die eine planare Einbettung (Knoten werden auf Punkte abgebildet) von 2-außenplanaren Graphen ermöglicht

Multispace & Multistructure. Neutrosophic Transdisciplinarity (100 Collected Papers of Sciences), Vol. IV

The fourth volume, in my book series of “Collected Papers”, includes 100 published and unpublished articles, notes, (preliminary) drafts containing just ideas to be further investigated, scientific souvenirs, scientific blogs, project proposals, small experiments, solved and unsolved problems and conjectures, updated or alternative versions of previous papers, short or long humanistic essays, letters to the editors - all collected in the previous three decades (1980-2010) – but most of them are from the last decade (2000-2010), some of them being lost and found, yet others are extended, diversified, improved versions. This is an eclectic tome of 800 pages with papers in various fields of sciences, alphabetically listed, such as: astronomy, biology, calculus, chemistry, computer programming codification, economics and business and politics, education and administration, game theory, geometry, graph theory, information fusion, neutrosophic logic and set, non-Euclidean geometry, number theory, paradoxes, philosophy of science, psychology, quantum physics, scientific research methods, and statistics. It was my preoccupation and collaboration as author, co-author, translator, or cotranslator, and editor with many scientists from around the world for long time. Many topics from this book are incipient and need to be expanded in future explorations
