Étudiée à travers un corpus de cinq auteurs scéniques – Romeo Castellucci, Pippo Delbono,Simon McBurney, Christoph Marthaler et François Tanguy, la représentation rhapsodique met en lumière une pratique théâtrale qui consiste à construire le spectacle à partir des composants du plateau : scénographie, jeu des acteurs et textes produits par les acteurs ou apportés comme« matériaux » de jeu. Le metteur en scène, devenu « auteur scénique », compose ainsi, en étroite relation avec les présences en scène une écriture scénique à l’intérieur de laquelle le texte,reconfiguré dans la partition scénique, déstabilise les attendus dramatiques. La caractéristique de cette écriture est de tresser les différents constituants entre eux et de se développer en séquences dramatiques, par un méticuleux travail de montage.Le paysage théâtral qui se dégage de cette étude place la réception au coeur du dispositif scénique. / Through the study of five scenic authors – Romeo Castellucci, Pippo Delbono, SimonMcBurney, Christoph Marthaler and François Tanguy, rhapsodic performance highlights a theatrical practice which consists of constructing the show with the stage components : scenography, the acting, and the text produced or introduced by the actor as the acting« material ». The director, who becomes the « scenic author », thus composes, in strict relation with the stage presence a scenic account in which the text, reworked in its scenic partitions,destabilizes the dramatic expectations. The characteristic of this technique is to harmonize the different constituents amongst themselves and to unfold into dramatic sequences, through ameticulous mounting process.The theatrical landscape revealed through this study places reception in the heart of the scenic device.

Antal installerade solcellsanläggningar har ökat drastiskt de senaste åren i Sverige, och utsikten för ökad mängd solel i Sverige är mycket god, med prognoser på kraftig tillväxt av installerade solcellsanläggningar de kommande åren. Detta med bakgrund att utvecklingen av solcellspaneler har gjort att priset har sjunkit, samt politiska beslut har gjort det lönsamt att investera i solcellsanläggningar i Sverige. Dessa förutsättningar har lagt grunden för en ny växande bransch, solcellsinstallationer. Risken vid en ny och snabbt växande bransch är att kunskapen inom ämnet för de som är verksamma inom branschen kan vara bristfällig samt oseriösa företag kan lockas av att tjäna snabba pengar på en lukrativ marknad. Efter en omfattande litteraturstudie visades att någon större kvalitésundersökning av solcellsinstallationer i Sverige, med avseende på hållfasthet ej har gjorts tidigare. Detta motiverade att denna undersökning var av hög relevans. Syftet med denna studie var att ta reda på om solcellsanläggningar monteras tillräckligt hållfast i Gävle-Dalaregionen med avseende på snö- och vindlast. Fjorton anläggningar har besökts för att samla in data. Data har sedan utvärderats i tre kategorier per anläggning. För att en anläggning skall bedömas som en godkänd skall alla dessa tre kategorier vara godkända. Bedömningen av solcellsanläggningarna gjordes i de tre kategorierna: 1. montagesystemets antal infästningar, 2. mått mellan infästningarna, 3. placering av solcellspanelerna i förhållande till montagesystemet. Resultatet visade att ingen av dessa anläggningar var godkända i samtliga tre kategorier. Vissa anläggningar var godkända i två av tre kategorier, medan två anläggningar var ej godkänd i någon kategori. Vid en summering av bedömningsresultatet för alla anläggningar i de tre montagekategorierna, visades att ca 20% ej gick att fastställa (pga. bristande information) ca 40% var godkända och ca 40% var ej godkända. Bedömningar har gjorts utifrån beräkningsprogram och anvisningar tillhandahållna av tillverkarna av de montagesystem och solcellspaneler som har använts i anläggningarna. Att ingen anläggning var godkänd i samtliga tre kategorier som undersöktes indikerar att solcellsmontage på tegeltak byggs ej tillräckligt hållfast i Gävle-Dalaregionen. Detta kan dock inte generaliseras för solcellsanläggningar på tegeltak i hela Sverige då mängden undersökta anläggningar var relativt liten och endast fördelade på två län i landet. Då det antas att installatörer avser att bygga korrekta anläggningar visar denna studie att kunskap om solcellsmontage med avseende på hållfasthet är bristfällig. Detta kan vara en följd av den stora efterfrågan på solcellsinstallationer, som kan medföra att stort fokus ligger på att installera anläggningar snabbt, och inhämtning av kunskap ej blir prioriterat. / The number of installed PV-systems (Photovoltaic systems) has increased rapidly in Sweden the last years, and the forecast for even more installations shows an increase for the coming years. Due to the price for PV-panels har dropped and political decisions for subventions of PV-systems has made it more profitable to invest in PV-installations in Sweden. These reasons have paved the road for a new growing branch, PV-installations. The risk of a new profitable, fast growing branch is that there might be short of knowledge for new installers, and the possibility that dishonest companies just want to take the advantage of the situation to make quick money, which can lead to installations poorly made.   After a search of published literature in strength of mounting for PV-panels there the result was that this is a rather unexplored subject, which motivated this investigation.   The aim of this study was to find out if PV-panels on tiled roofs were installed correct due to the snow load and wind load in the region Dalarna and Gävleborg in Sweden.   Fourteen PV-systems has been studied and evaluated. When the evaluation of the PV-systems were made the following criteria were considered: number of fixing attached to the roof of the mounting, distance between mounting fixings and how the PV-panels were installed relative the construction of the mounting. A PV-system had to be installed correctly for all three criterias to be considered approved. The result of this work shows that none of the evaluated systems were installed correctly. Some systems were approved in two of the criteria, while two systems were not approved in any of the criteria. The evaluation was made due to calculation programs and instructions from the manufacturers of mounting and PV-panels.   The fact that none of the PV-systems were approved for all three criteria implies that the installations of PV-systems are not made strong enough. This result is not stated for all installations in Sweden because the number of studied PV-systems were not big enough, and the area of the studied installations were rather small. Basis of snow load and wind load variates quite much in Sweden depending on region. It is assumed that designers and constructors attempt to install PV-systems correct, therefor shows this work that there’s a lack of knowledge for construct installations strong enough. This may be a result of the fast increase of PV-installations, where the priority lays in installing many PV-systems, not in education and search of knowledge.

As part of Nigeria’s drive to increase electricity production capacity and shift to renewable sources, a new 50 MW photovoltaic (PV) plant is proposed for a town in north-west Nigeria. Rather than using conventional monofacial modules and fixed mounting, it is of interest to consider a selection of new technologies which are attracting growing attention in the global utility PV market. These can increase energy output, and could be used to advantage in this 50 MW plant. However, the technologies, namely bifacial modules and solar tracking, are more expensive than their conventional counterparts, while their relative performance depends on the latitude and climate of the plant location. Thus their economic benefit cannot be taken for granted. The aim of this study is to propose multiple designs for the 50 MW plant using different combinations of module and mounting technologies, finding their economic order of merit by estimating their respective levelised costs of electricity (LCOEs).Using the simulation software PVsyst, the electricity production of different plant layouts and component configurations was estimated. Key parameters such as tilt angle and pitch distance were varied in order to optimise each configuration of technologies. Having sourced economic data from the industry and literature, lifetime plant costs were calculated, which in combination with lifetime electricity production, were used to estimate the LCOE.As expected, results indicated that the optimum configuration was bifacial modules mounted on horizontal single-axis tracking (SAT), followed by monofacial modules on horizontal SAT. Fixed installations had greater LCOEs by a reasonable margin, while the LCOE difference between monofacial and bifacial modules on fixed mounting was within the error of the calculation, meaning this choice relies on more accurate input data. A sensitivity analysis allowed uncertainty in the results to be gauged, and highlighted the factors which most influence LCOE, so that efforts to increase profitability can be focussed in the right places. Finally, suggestions are offered to help optimise bifacial and tracking installations by comparison with conventional plants.The conclusions drawn herein will be specifically relevant to the Swedish developer and EPC contractor Svenska Solenergigruppen which, in due course, will submit a plant design proposal to the project developer of the 50 MW plant. However, it is hoped that this work will act as a guide for any EPC contractor or developer working on a utility PV plant in sub-Saharan Africa, allowing efficient design of an optimal system.

Linjett Segelbåtar konstruerar och producerar högkvalitativa  segelbåtar på Rosättravarvet. Detta arbete syftar till att presentera en bättre mekanisk lösning till den nedgångslucka som Linjett har idag. Förbättringen består i att sänka produktionskostnaderna, underlätta montering och service men framförallt öka livslängden på mekanismen. Nedgångsluckan är den vertikala ”dörr” som skiljer utsidan från insidan på en segelbåt. I Linjett’s befintliga lösning så skjuts luckan ned i en balja under durken och försvinner undan på ett väldigt smidigt sätt. Tack vare en gasfjäder görs den annars ganska tunga luckan viktlös och kan lämnas halvöppen vilket kan vara väldigt praktiskt, det är en typ av funktion som den nya lösningen måste bibehålla. Arbetet har följt en generisk utvecklingsprocess. Koncept från en idégenerering har ställts mot varandra med hjälp av en pughmatris och en multiomröstning. Det vinnande konceptet har sedan förbättrats i en iterativ process för att uppfylla målen i så hög utsträckning som möjligt. Under vidareutvecklingen har fokus legat på att minimera antal komponenter genom DFA (Design For Assembley). För att motivera lösningen har monteringsscheman ställts upp och kompletterats med en självkostnadskalkyl. Dessa detaljstuderas och utvärderas för att agera beslutsunderlag till Linjett. Den presenterade lösningen använder konstantkraftsfjädrar för att bära upp luckans vikt. Dessa fjädrar ger lång livslängd i dessa utsatta miljöer och har ett förhållandevis lågt inköpspris. / Linjett Segelbåtar constructs and produces high quality sailing yachts at Rosättravarvet. This rapport aims to enhance the mechanical solution of the companionway door that Linjett is using. The enhancement consists in lowering production costs, simplify the mounting and service but most important, raise the lifetime of the mechanism. The companionway door is what separates the outside from the inside on a sailing yacht. Linjett has a special solution were the companionway door slides in under the cockpit floor and disappears in a clever way. Thanks to a gas spring the otherwise heavy door becomes weightless and can be left at any desired height which can come in handy. This is one of the function that the new solution must maintain. The work has followed a generic developmentprocess. Concepts from a brainstormingsession have been evaluated and compared in a pughmatris and a multivote. The winning concept has then been improved in a iterative process to fulfill the goals in the best way possible. During the enhancement of the concept there has been a strive to minimize the number of components throughout DFA (Deisgn for Assembley) To motivate the solution a mounting schedule was produced which in turn were complemented by a cost price calculation. These were studied in detail and evaluated to create a basis for decision making to Linjett. The presented solution uses constant force springs to carry the weight of the companionway door. Springs of these type provide long lifetime in these harsh conditions and is reasonably priced.

The Aurora zone is an ore zone which was recently discovered in the Björkdal gold mine, northern Sweden, and it has been the main focus of mining and exploration activities for the past few years (Pressacco et al., 2020). The purpose of this project is to determine how gold occurs in the Aurora zone. A three-day long campaign was therefore done at the processing plant at the Björkdal mine where 11 000 tonnes of ore from the drive Aurora 370/1650 E+W were processed. The issue regarding the ore from the Aurora zone is that it has a lower recovery compared to the rest of the mine.  Six chip samples, 12 samples from the ingoing plant feed and two tailing samples were analyzed using optical microscopy, scanning electron microscopy (SEM), and automated mineralogy (QEMSCAN). This was done to determine the mineralogy, grain size distribution, mineral associations, textures and modal mineralogy which all are factors that could influence the metal recovery at the processing plant. The samples were prepared using the cold mounting method and epoxy mounts were created. After cutting, grinding, and polishing, the sections were ready to be examined. Optical microscopy was performed using a Nikon ECLIPSE E600 POL microscope. Ten epoxy mounts were carbon coated and automated mineralogy was performed on nine of them in a ZEISS Sigma 300 VP using a recipe (analysis mode) for “bright phase search”. Manual point-ID analysis was done using a ZEISS MERLIN SEM. Fifty gold grains were identified in this study, 48 of them in the chip samples and two of them in the ingoing-feed samples. 64% of them were associated with silicates, 22% were quartz associated, 12% were associated with bismuth minerals and 2% of them were associated with sulfides. The grain size distribution has a range between 0.7 and 19 μm and the median grain size is 4.8 μm. The gold grains identified from the Aurora zone have a significantly smaller median grain size than gold from other parts of the mine. The majority of the gold grains identified in this study, have a very fine grain size, are mainly associated with silicates and most prominently occur as inclusions. Gold that occurs in this way is typically difficult to recover in the processing plant and it seems like this is the main reason for the lower gold recovery from the Aurora ore zone.  No gold was found in the tailings, suggesting that the mineral process is performing well although no thorough conclusion can be made in regards of the processing. The lack of data for the different sample types in this project is an issue. Gold from the tailings must be identified and examined to draw any clear conclusions regarding the processing. For future work, it is therefore recommended to analyze more tailing samples and to implement hydroseparation at the sample preparation stage, to separate the heavier gold particles from lighter minerals. Then more gold will most likely get detected in the tailing samples.

Der derzeitige technische Fortschritt stützt sich maßgeblich auf die Nutzung von elektrischem Strom. Der Anteil der Stromerzeugung aus Sonnenlicht hat mittlerweile in Deutschland den der Wasserkraft überschritten, der 1990 noch der größte regenerative Energielieferant war. Die Technologie der Photovoltaik (PV) wandelt die hochenergetische Strahlung der Sonne in elektrischen Strom um und nutzt dabei häufig Glasplatten als tragende Struktur. Der Hauptanspruch dieser Arbeit liegt in der Entwicklung und Untersuchung eines Befestigungssystems mit einer höher- oder hochmoduligen Klebverbindung zum gläsernen PV-Modul sowie einer möglichst universell einsetzbaren Fügeverbindung zur Unterkonstrukion. Die systematische Enwicklung der Fügeverbindung zum PV-Modul basiert auf dem Ansatz eines flexiblen, stützenden \\hbox{Ringes} für das Fügeelement (Halter), um die durch eine mechanische Belastung der Module induzierten Zugspannungen im Glas über der Fügeelementkante zu reduzieren. Eine neuartige, kombinierte Klammer-Keil-Verbindung sichert die Befestigung auf einer von ihr unabhängigen Unterkonstruktion sowohl quer als auch längs zur Schienenrichtung. Experimentelle Arbeiten charakterisieren die eingesetzte Klebverbindung unter verschiedenen Beanspruchungsszenarien, um sowohl konstruktions- als auch klebstoffbedingte Möglichkeiten und Grenzen der Fügeverbindung für die vorliegende Anwendung zu identifizieren. Die Untersuchungen weisen zudem geeignete Vorbehandlungsmaßnahmen der Aluminiumoberflächen aus. Sowohl numerische Simulationen als auch die neuartig eingesetzte Nahbereichsphotogrammetrie bestätigen in Bauteiluntersuchungen die vorteilige Wirkung des flexiblen, höhermodulig geklebten Ringes. Die vorliegende Arbeit setzt sich hierbei auch kritisch mit unterschiedlichen Einflüssen auf die Ergebnisse auseinander, die einerseits durch verschiedene Prüfstände hervorgerufen werden können und andererseits auch den verwendeten Methoden zugrunde liegen. / Today much of technical advances are due to the usage of electricity. The contribution of solar power to the production of electricity in Germany currently surpasses water powered electricity which was in 1990 the almost exclusive renewable energy source. The technology of photovoltaic systems based on high-powered sun radiation, often utilizes glass plates as a supporting structure. This dissertation primarily focuses on the research and development of a mounting system with a higher or high modulus adhesively bonded joint to the PV-module as well as an all-purpose connection to the substructure. The systematical development process of the connection to the PV-module is based on the approach of a flexible supporting ring-shaped mounting element. This reduces the tension within the glass surface at the edge of the mounting element when mechanically loading the PV-module. A novel connection using a clamp-wedge combination ensures the ability to mount the PV-module horizontally or vertically to the rail substructure. Through the development process, the bonded joint is exposed to various scenarios where the construction as well as the adhesive possibilities and limitations under each scenario are analyzed. Research outcomes yield recommendations for appropriate pre-treatment of the aluminum surfaces. Numerical simulations as well as the novel use of the near-field photogrammetry method confirmed beneficial action of the flexible ring-shaped mounting element within assembly testing of large glass specimens. This dissertation discusses how different variables can have a considerable effect on results when introduced through the testing device and through monitoring methods.
