An international consortium of more than 150 organisations worldwide is studying the feasibility of future particle collider scenarios to expand our understanding of the inner workings of the Universe. The core of this Future Circular Collider (FCC) study, hosted by CERN, an international organisation near Geneva (Switzerland), is a 100 km long circular particle collider infrastructure that extends CERN's current accelerator complex. As a first step, an intensity frontier electron-positron collider is assumed. The ultimate goal is to build a proton collider with an energy seven times larger than the Large Hadron Collider (LHC). Such a machine has to be built with novel superconductive magnet technology. Since it takes decades for such technology to reach industrial maturity levels, R&D has already started. The superconducting magnet system is considered the major cost driver for construction of such a proton collider. A good cost-benefit balance for industrial suppliers is considered an important factor for the funding of such a project. Aim The aim of this investigation was to identify the industrial impact potentials of the key processes needed for the manufacturing of novel high-field superconducting magnets and to find innovative additional applications for these technologies outside the particle-accelerator domain. Suppliers and manufacturing partners of CERN would benefit if the know-how could be used for other markets and to improve their internal efficiency and competitivity on the world-market. Eventually, being more cost-effective in the manufacturing and being able to leverage further markets on a long-time scale will also reduce the cost for each step in the manufacturing chain and ultimately lead to lower costs for the superconducting magnet system of a future high-energy particle collider. Method The project is carried out by means of the Technology Competence Leveraging method, which has been pioneered by the Vienna University of economics and business in Austria. It aims to find new application fields for the three most promising technologies required to manufacture novel high-field superconducting magnets. This is achieved by gathering information from user-communities, conducting interviews with experts in different industries and brainstorming for new out-of-the-box ideas. The most valuable application fields were evaluated according to their Benefit Relevance and Strategic Fit. During the process, 71 interviews with experts have been carried out, through which 38 new application fields were found with credible impacts beyond particle accelerator projects. They relate to manufacturing "superconducting Rutherford cables" (15), "thermal treatment" (10) and "vacuum impregnation with novel epoxy" (13). Superconducting magnet manufacturing technologies for market-oriented industries Report. Results: A short description of all application fields that were classified as "high potential" can be found here: Superconducting Rutherford cable * Aircraft charging: Commercial airplanes only spend around 45 minutes on the ground at a time to load and unload passengers. For future electric aircraft this time window would be to small to charge using conventional cables. The superconducting Rutherford cable could charge an electric plane fast and efficiently. * Electricity distribution in hybrid-electric aircraft: On a shorter time scale, hybrid-electric aircraft is an appealing ecological technology with economic advantages. In this case, electricity for the electric engines is produced by a generator. Cables with high current densities are needed inside the aircraft to distribute the energy. The superconducting Rutherford cable could be a candidate for this task. * Compact and efficient electricity generators: Using the superconducting Rutherford cable, small and light engines and generators can be constructed. One end-use example is for instance the generation of electricity using highly-efficient wind turbines. Thermal treatment: Heat treatment is needed during the production of superconducting magnet coils. In this processing step, the raw materials are reacted to form the superconductor. This processing step is used for certain lowtemperature superconductors as well as for certain high-temperature superconductors. * Scrap metal recycling: Using a large-scale oven with very accurate temperature stabilisation over long time periods, melting points of different metals can be selected. This leads to more efficient recycling of scrap metal. It also permits a higher degrees of process automation and quality management. * Thermal treatment of aluminium: Thermal treatment of aluminium comprises technologies like tempering and hardening. The goal of this technique is to change the characteristics of aluminium and alloys containing aluminium. End-use applications include for instance the automotive and aerospace industry, where such exact treatment is necessary. Vacuum impregnation * Waste treatmnent companies currently face challenges because new legislation require more leak-tight containers. Novel epoxy resin developed for superconducting magnets in particle colliders also needs to withstand high radiation levels. Therefore, this technology can be useful in the process of managing highly-activated radioactive waste.

Examensarbetet har bedrivits vid Tekniska Högskolan i Jönköping och i samarbete med fallföretaget Solutions for Tomorrow AB. Arbetet har utformats efter ett syfte; att utveckla ett produktkoncept där alternativa material och tillverkningsmetoder leder till kostnadsbesparingar. Syftet har sedan brutits ned till fyra frågeställningar som arbetet kretsar kring. Två frågeställningar behandlar redan framtagna koncept och två rör ekonomiska aspekter för nya projekt. För att besvara frågeställningarna är arbetet utformat som en konceptstudie där hela utvecklingsprocessen har genomförts. Studien är framför allt baserad på en kvalitativ metod där fokus har legat på intervjuer och textanalyser. En deduktiv ansats har använts då kända teorier och modeller har tillämpats vid antagande av slutsatsen. Studien har resulterat i två produktkoncept som beräknas sänka produktionskostnaderna för den analyserade komponenten. En mer kostnadseffektiv tillverkningsmetod kan innebära att nya leverantörer kan komma att kontaktas och nytt ritningsunderlag måste framställas. I framtiden bör en mer omfattande konstruktionsanalys av komponenten genomföras, då nya material och tillverkningsmetoder erbjuder nya möjligheter till kostnadseffektivisering. De kostnadsberäkningar som görs i rapporten utgår i många fall från den tillverkningsmetod som används och tiden det tar att utföra olika steg i processen. Delar av produktionen ligger idag i Tyskland och ingen möjlighet gavs att bevittna processen. De kostnader som är relaterade till arbetstiden är därför uppskattade. Kostnadskalkyleringarna för koncepten beräknas ha en viss felmarginal och bör inte användas vid beslutstagande. / This thesis project has been conducted at the School of Engineering at Jönköping University and in cooperation with the case company Solutions for Tomorrow AB. The project was modeled around a purpose; to develop a product concept where alternative materials and manufacturing techniques will lead to cost savings. The purpose was broken down into four questions around which the project is focused. Two of the questions are about the produced concepts and two of them are about the economic aspect of the new concepts. To answer the questions the thesis project is designed as a conceptual study where the whole development process has been carried out. The study is mostly based on a qualitative method where focus has been on collecting data from interviews and related literature. A deductive approach was used since known theories and models has been applied when assuming the conclusions. The study has resulted in two product concepts that according to the calculations will lower the production related costs. A more cost efficient manufacturing method implicates that new suppliers might be needed and new production drawings needs to be fabricated. A more extensive constructional analysis should be conducted in the future since new materials and manufacturing methods offers new possibilities to further cost potentiation. The cost calculations that are performed in this report are in many cases based on the manufacturing methods used today and the time it takes to perform the steps in the production. Parts of the present production are located in Germany and no opportunity was given to witness the process. The costs related to the manufacturing time are therefore estimates. Hence the cost calculations are expected to have a certain error margin and should not be used in decision making.

M. Ing. / According to Taque (2005: 30), current lean manufacturing can be presented as ineffective due to a lack of guidelines for establishing and implementing the application thereof. In this project, guidelines for the implementation of lean manufacturing were developed using data collected from multiple sources. One of these sources were company visitations conducted at Desta Power Matla (DPM) in Johannesburg and Bosch SA in Brits. In addition, interviews were conducted with an expert in the field of lean manufacturing, ECSA-accredited professionals in the field, academics in industrial engineering and workers who use lean manufacturing. The significance of this study lies in assisting employees in understanding lean manufacturing production and then developing and implementing guidelines for its implementation. The study also brings to the fore the role of the individual worker in acquiring knowledge about and an understanding of lean manufacturing guidelines. This will ultimately enable companies to implement lean manufacturing production successfully. The results emerging from the data were used to develop guidelines for lean manufacturing production.

Forging operation is one of the most commonly used manufacturing techniques in defense industry. The products of forging operation have higher material strength when comparing to traditional manufacturing operations. Especially, for the mass production, it is a beneficial method considering metal and cost saving. The commonly used part named Fin Connector Rod in defense industry requires high material strength due to working conditions. In this thesis, manufacturing of this part by hot forging operation is accomplished after analyzing by using the finite element method. Two alternative forging processes are compared and the applicable alternative method is selected by using a finite element program. Dies are designed for applied processes. The stress distribution and the current temperature variation within the parts analyzed to evaluate the results. The fin connector rod is manufactured according to the results of the finite element analysis. It has been observed that, manufacturing of the fin connector rod by hot forging is succeeded and the waste material and cost is reduced when compared to the machining operation which is being used currently.

Magister Artium (Development Studies) - MA(DVS) / The objective of this research is to investigate the factors at plant level which impact on the diffusion of Japanese Manufacturing Techniques to enterprises in developing countries generally, and South Africa specifically. This informs the development of meaningful supply-side measures to improve the competitiveness of South African manufacturers. This has been achieved through both a thorough examination of the literature and through field research. The field research documents the implementation experiences in fifteen South African plants which participated in the Shopfloor Best Practice workshops of the Manufacturing Roundtable (MRT). I chose to examine these examples of transfer as I was a participant researcher, attached to the MRT. The central question which guided my research is what are the factors which affect the depth of systemic adoption of Japanese Manufacturing Techniques on the shopfloor in South Africa, and what this indicates for the breadth of diffusion of the techniques across the manufacturing sector as a whole. The research argument is that for sustainable adoption both social and technical aspects of Japanese Manufacturing Techniques need to be addressed. Focusing on the technical aspects only and presenting a universally applicable model obscures the realities of transfer, as the embeddedness of the techniques in the social and institutional context is ignored. The point of departure for analysis in this thesis is thus real examples of transfer, as opposed to a universally defined and abstracted model. The experience and opinions of the workshop participants, and those of managers in their plants, have been gathered through individual in-depth interviews and site visits. The evidence indicates that there are many factors both internal and external to the firm which are likely to constrain significantly the ability of some firms to move in the systemic direction. These include the poor primary education of much of the workforce, poor management skills, wage and social inequality and a lack of participation in the workplace. It becomes apparent that the process of diffusion amongst South African manufacturers is not likely to be rapid or steady, and that the most likely path is one of uneven diffusion.

Cette recherche porte sur la production céramique du Bronze ancien IV (2500-2000 av. J.-C.). L'objectif principal de cette thèse est de caractériser le matériel céramique de la région qui se trouve à l’est de la moyenne vallée de l’Oronte, en particulier la steppe syrienne (Bādiyat Al-Shām), et d'établir des jalons chronologiques solides des différents niveaux et phases de la deuxième moitié du IIIe millénaire. Pour atteindre ces objectifs, cette étude s’appuie sur les données de trois sondages stratigraphiques que j’ai réalisés dans le cadre des fouilles syriennes sur les sites suivants : Mishrifeh-Qatna, Tell Shʻaīrat et Tell Al-Ṣūr. Ont été également étudiées les céramiques provenant d’une série de prospection effectuées sur plusieurs régions de Syrie centrale. Cette étude ne s’est pas limitée à l’approche morphologique et stylistique mais elle y a ajouté des analyses technologiques, minéralogiques et physico-chimiques réalisées sur le matériel de plus de 35 sites inédits de Syrie centrale, afin d’étudier les modalités de production et de distribution de la céramique pendant la deuxième moitié du IIIe millénaire dans cette région et d’essayer de déterminer la localisation des centres de production. En croisant les résultats des fouilles avec ceux de l’étude du matériel céramique, nous avons tenté de replacer cette région encore inexplorée dans son contexte chronologique et historique. / This research focuses on the ceramic production of the Early Bronze Age IV (2500-2000 B. C.). The main goals of the thesis is to characterize the ceramic material in the region located east of the middle Orontes valley, mainly the Syrian steppe (Bādiyat Al-Shām), and to establish solid chronological landmarks for the diverse levels and phases of the second half of the third millennium. To reach its goals, this study includes data provided by three stratigraphical soundings which I made in the frame of Syrian excavations at Mishrifeh-Qatna, Tell Shʻaīrat et Tell Al-Ṣūr, as well as the data of a series of surveys in several regions of Central Syria. Morphological and stylistical approaches have been successfully combined with the results stemming from technological, mineralogical and chemical analyses carried out on the material from more than 35 sites in Central Syria, aiming to study pottery production and distribution modalities during the second half of the third millennium BC in Central Syria, to try to identify the location of production centres and to reconstruct the networks of exchanges. Combining the excavations results with the ceramic studies we attempted to set this previously unexplored region in its chronological and historical context.

La version intégrale du mémoire a été déposée à la Division de la gestion des documents et des archives. / Le Staffordshire Hoard est un trésor anglo-saxon qui date des 6e et 7e siècles qui fut découvert en juillet 2009 par un détectoriste dans un champ du comté du Staffordshire en Angleterre. Ce trésor est composé d’environ 4600 fragments d’artéfacts représentant pour la plupart des garnitures d’épées en or et en argent. Bien que nous retrouvions aussi dans le Hoard certains objets ecclésiastiques, comme une grande croix en or ainsi qu’une bande inscrite en latin, aucune pièce de monnaie ne fut retrouvée, ni aucune lame d’épée. Le Staffordshire Hoard pose beaucoup de questions, notamment par sa composition inédite et aussi en raison du mauvais état dans lequel les objets furent retrouvés. Depuis sa découverte en 2009, les chercheurs se sont majoritairement posé les mêmes questions, à savoir de quel type de Hoard il s’agit, à qui il appartient et pourquoi il fut enterré. Avec ce mémoire, nous allons plutôt emprunter un autre chemin. En effet, nous étudierons plutôt les aspects matériels et techniques de la construction des artéfacts en or décorés avec la technique du cloisonné, et particulièrement le seax set. Ceci nous permettra dans un premier temps de comprendre comment ce type d’objet fut fabriqué par une société en particulier à l’époque du haut Moyen-Âge. Dans un second temps, l’étude de ces sujets aidera à répondre à une question qui fut souvent mise de côté par les différents chercheurs s’étant intéressés au Staffordshire Hoard, à savoir pourquoi aucune lame d’épée ne fut retrouvée dans cet assemblage. / The Staffordshire Hoard is an Anglo-Saxon treasure dating from the 6th and 7th centuries that was discovered in July 2009 by a detectorist in a field in the county of Staffordshire, England. This treasure is composed of approximately 4600 fragments of artefacts representing mostly gold and silver sword fittings. Although some ecclesiastical items were also found in the Hoard, such as a gold Great Cross and a Latin inscribed strip, neither coins nor sword blades were found. The Staffordshire Hoard raises many questions, due to its unusual composition and the poor condition in which the objects were found. Since its discovery in 2009, researchers have mostly asked the same questions, namely what type of hoard it is, to whom it belongs and why it was buried. With this dissertation, we will take a different path. Instead, we will study the material and technical aspects of the construction of gold artefacts decorated with the cloisonné technique, specifically the seax set. This will allow us in first place to understand how this type of object was made by a particular society in the early Middle Ages. Secondly, the study of these objects will help us to answer a question that has often been put aside by various researchers interested in the Staffordshire Hoard, namely why no sword blades were found in this assemblage.
