Texte intégralRésumé :
The present Master´s thesis deals with the concept of press drive of Blanking press LKDS 800 used for blanking in automatic blanking line. The first part of the thesis is dedicated to the individual arrangements of press drives and servo press drives and to the description of main components. The second part of this thesis deals with the structural design of the drive. Based on the computation of the crank mechanism, several design solutions were suggested. From these solutions, the option with the lowest drive height is selected. This option, offers the computation of the main drive, flywheel, spur gearing and clutch/brake combination. This computation is followed by computations of individual construction nodes, which include a design and dimensioning of the individual joggles, shafts and bearings. The drawing of the press and clutch shaft assemblies with a list of items are also included.

Texte intégralRésumé :
Undervattensmaskinen YT-800 är en av Weda ABs största rengöringsrobotar som säljs och används idag. För att lyckas sälja och marknadsföra denna produkt på bästa möjliga sätt anser Weda att ju mer data de har för produkten, ju mer attraktiv blir det för framtida potentiella kunder. Därför var en av Wedas mål att sammanställa en CAD-modell av undervattensmaskinen med tillhörande ritningar. Eftersom Wedas personal saknar denna kunskap erbjöds dokumentationsuppdraget som ett dokumentationsprojekt för två studenter vid KTH i Södertälje. Under denna process samlades information om urval av material, tolerans, ritningsformat och CAD-monteringsförfarande för att erhålla de nödvändiga resurserna för att utföra dokumentationen. Med en uppdatering av produktritningarna är det möjligt att beställa produkter utan behov av andra företag.The underwater machine YT-800 is one of Weda AB's largest cleaning robots sold and used today. To succeed in selling and marketing this product in the best possible way, Weda thinks that the more data they have for the product, the more attractive it will be to future potential customers. Therefore, one of Weda's goals was to compile a CAD model of the underwater machine with associated drawings. Since Weda's staff lacks this knowledge, the documentation assignment was offered as a thesis project to two students at KTH in Södertälje. During this process, information on the selection of material, tolerance, drawing format and CAD assembly procedure was gathered to obtain the necessary recourses to perform the documentation. With an update of the product drawings, it is possible to order products without the need of other companies.

Cruickshanks, Gemma Louise. « Iron in Iron Age Scotland : a long-term case study of production and use c.800 BC to AD 800 ». Thesis, University of Edinburgh, 2017. http://hdl.handle.net/1842/23501.
Texte intégralRésumé :
This thesis examines the evidence for iron production and use during the Scottish Iron Age, circa 800 BC to AD 800, and is the first attempt at synthesising this evidence for Scotland. The broad aim is to gain a better understanding of the development, organisation and scale of iron production throughout this period. Four regional case studies focussing on Orkney, Skye, the Lothians and the Moray Firth provide the opportunity to examine different aspects of this aim through analysing excavated ironworking debris, iron artefacts and their context. Proxy evidence is also examined, namely whetstones and toolmarks on bone/ antler assemblages, in order to fill in some of the gaps in the iron artefact record due to poor preservation or ancient recycling. Some 500kg of ironworking debris, over 1500 iron artefacts, around 200 whetstones and over 2000 worked bone/ antler artefacts from the four regions were examined. The regional case studies are followed by a Scotland-wide discussion will also place the Scottish evidence within its wider context. The research shows rare, sporadic early evidence for iron production and use from around 800BC in Scotland, with production sites and iron artefact assemblages noticeably increasing from around 400BC. The Moray Firth area provides evidence of several intensive ironworking sites, while the Lothians have produced scant evidence, demonstrating regional variation in iron production across Scotland. The long settlement sequences of Orkney allow chronological variations to be examined, revealing changes in iron production organisation from the Middle to Late Iron Ages. Some of the earliest iron artefacts in Scotland, from a ritual cave site on Skye, provide the opportunity to examine structured deposition of iron, with similar depositional patterns identified across Scotland. The use of proxy evidence fleshes out the picture, revealing common use of tools such as iron saws, which rarely survive archaeologically.

Texte intégralRésumé :
Denna rapport utgör civilingenjörsexamensarbete på institutionen för maskinkonstruktion på Kungliga Tekniska Högskolan. Arbetet har utförts år 2009 på Siemens Industrial Turbomachinery AB (SIT AB) i Finspång. Syftet med arbetet är att minska läckaget av kylluft vid ledskena 2 på SGT-800, med hänsyn tagen till kostnad och verkningsgrad. Arbetet utgick från en bakgrundstudie där problemet fastställdes och en kravspecifikation sammanställdes. Effekter och kostnader av kylluftsreduceringen låg till grund för beräkningarna. Fem grundkoncept genererades med utgångspunkt från kravspecifikationerna. Konceptgenereringen och evalueringen grundar sig på Ullman, The Mechanical Design Process och Liedholm, systematisk konceptutveckling . Koncepten genomgick en grovsållning, med hjälp av en enkel evalueringsmatris, där ett av dem dömdes ut. Resterande fyra grundkoncept expanderades till 14 detaljkoncept vilka genomgick en mer sofistikerad evaluering, där ett koncept visade sig reducera kylluften effektivt till en ringa kostnad. Det vinnande konceptet bestod av en c-tätning, vilken lödes till ledskenans sugsida, varvid tätningen kontraheras av ledskenans värmeutvidgning. Denna studie har visat att värdet av den ökade verkningsgraden är större än kostnaden att införa den rekommenderade konstruktionsändringen.This report represents a Master of Science thesis at the department of machine design at The Royal Institute of Technology. The work was executed at Siemens Industrial Turbomachinery AB in Finspong in 2009. The purpose of this work is to investigate possible concepts in order to reduce cooling air leakage at guide vane 2 in SGT-800, due to cost and efficiency. On basis of a background study, the technical specifications were elaborated, in which the demands and wishes were elucidated. Based on the problem itself and the delimitations, five different conceptual ideas were generated. The concept generation and evaluation rests mostly upon Ullman, The Mechanical Design Process and Liedholm, systematisk konceptutveckling. The conceptual ideas were put together and the combinations went through a rough evaluation procedure where one of the concepts was eliminated. The remaining four concepts were expanded to 14 more detailed concepts, of which one stood as a winner after the sophisticated evaluation matrix. The winning concept was a c-ring, brazed to the suction side, where the seal contracts due to the thermal expansion of the vane. This study has shown that the value of the gained efficiency is greater than the cost of the suggested design modification.

Texte intégralRésumé :
Ever since Schliemann's excavations in the Argolid, the area has been popular with archaeologists. One hundred years later the Geometric period is fairly well known in certain aspects but in other ways it is still unclear and even less is known about the immediately succeeding period, the early Archaic. The aim of this thesis, therefore, is to present the archaeological evidence for both the later part of the Geometric and early Archaic periods, the eighth and seventh centuries, and to examine the differences and the changes that occur within that time at the various sites, noting in particular the contrasts between the eighth and seventh century. This is a purely archaeological survey; historical accounts are not considered except in passing. The thesis attempts to put into proper perspective the position of Argos in relation to her neighbours in the Argolid, and the position of the eastern peninsula in relation to the central plain. Reasons are also suggested for the sudden and important changes noticeable in the seventh century. All the major facets of the archaeological evidence are presented, each in its own chapter beginning with the sites themselves, including distribution maps and a site index. Trends in settlement patterns from the LHIIIB to the Archaic period are noted, with particular attention to the Geometric and Archaic. The graves are then considered with an index of all graves of the eighth and seventh centuries. Contrasts and comparisons are made between the periods at each site. Pottery is examined by period and site, then metalwork in terms of the different types of artifacts found in the eighth and seventh centuries. The evidence of terracottas is treated in the same way and inscriptions and script are studied; finally the evidence for sanctuaries and cults brings together much of the previous material.

Texte intégralRésumé :
Lo scenario politico contemporaneo risuona di ossessivi riferimenti all’identità, alla cui salvaguardia sembrano sacrificabili margini sempre più ampi di libertà e diritto, mentre la retorica della sicurezza fa proprie le immagini dell’assedio, dell’invasione e della contaminazione. Le stesse paure sono rintracciabili lungo tutto il corso della storia e ognuna ha inventato forme mostruose, in una costante dialettica fra “ritorno” e metamorfosi: il corpo del mostro è un corpo frammentato e impuro; è un corpo grottesco, perché travalica i limiti; lungi dall’essere un mero riflesso dell’inconscio, non solo può appartenere alla problematicità di ciò che chiamiamo “sé”, ma rispecchia la profonda ambiguità del nostro rapporto con i concetti di unità e uguaglianza., a un tempo oggetto di desiderio e di repulsione. Il presente lavoro vuole studiare la letteratura attraverso la categoria di la mostruosità, al fine di ripensare il valore del confine e il ruolo politico delle narrazioni letterarie e culturali.

Larsson, Heléna. « Omkonstruktion av avtappningens inloppsrör på utloppsdiffusorn på SGT-800 ». Thesis, Linköpings universitet, Maskinkonstruktion, 2011. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-69004.
Texte intégralRésumé :
Detta examensarbete har gått ut på att finna en ny konstruktionslösning på uttlopps-diffusorns inloppsrör på gasturbin SGT-800. Arbetet har utförts på Siemens Industrial Turbomachinery AB i Finspång på avdelning RCTD (gasturbinkonstruktion). Målet med projektet har varit att ta fram en konstruktionslösning som underlättar för svetsmontörerna på site när det gäller installation av inloppsrören, samt reducerar monteringstiden. Målet har även varit att ta fram en kostnadsjämförelse för totalkostnaden mellan den nya och originalkonstruktionen. Den metodik som har använts till detta arbete är Voice of the customer samt Systematisk konceptutveckling som baseras på bl.a. Vladimir Hubkas princip. Även original-konstruktionen har undersökts via ritningar och bilder tagna från tidigare sitemontage. Originalkonstruktionen skickas idag till site omonterad tillsammans med utlopps-diffusorn direkt från SIT AB:s underleverantör KSG AB i Surte för att sedan monteras och svetsas fast på site. P.g.a. att inloppsröret måste monteras i vinkel samt att utloppsdiffusorn är rund till formen, måste svetsning idag ske med elliptisk hålpassning. Detta leder till att det är svårt att få rör och hål att passa ihop utan att modifieringar måste göras på något av dessa. Via intervjuer och brainstorming skapades 17 olika koncept, varav nio togs vidare för utvärdering med hjälp av de kundkriterier som tagits fram. Denna utvärdering resulterade i att sex koncept gick vidare till ytterligare en utvärdering, där slutligen tre koncept plockades bort. Genom jämförelse mellan de tre kvarvarande koncepten, valdes slutligen ett vinnande koncept. Det nya konceptet består av två rördelar där det övre röret har samma innerdiameter som det nedre rörets ytterdiameter. Detta ger montörerna möjligheten att justera rörets höjd och dess vinkelpassning till den bälg som sammankopplar inloppsröret med avtappningsröret. Den övre rördelen har svetsats fast på utloppsdiffusorn före transporteringen till site. För att montera ihop dessa rör krävs det att de svetsas ihop. Detta var ett monteringssätt som montörerna ville undgå. Dock har detta lösts genom att kapa de båda rördelarna så att passning och svetsning sker på runda mynningar. Det kommer även med största sannolikhet finnas möjligheter att minska rörets diameter, vilket minskar rörets totala vikt. Den nya lösningen kommer uppskattningsvis att reducera installationstiden på site med upp till 60 % jämfört med originalkonstruktionen. Detta kommer att ge en installationskostnad proportionellt minskad mot installationstiden. Det övre rörets installationsbehov före sitetransport kommer att generera en tillverkningskostnad som uppskattningsvis förblir densamma som för originalkonstruktionen. Den totala kostnaden för den nya konstruktionen kommer att minskas med ca 45 % jämfört med originalrören. Förhoppningen är att detta projekt genererat ett intresse hos SIT AB att gå vidare och göra en konstruktionsförändring på denna komponent, för att underlätta vid framtida montage.In this examination paper, the bleed air inlet pipe on the exhaust diffuser for gas turbine STG-800 has been redesigned. The project has been performed at Siemens Industrial Turbomachinery AB in Finspång at the design department for gas turbines, RCTD. The aim for this project has been to develop a solution that makes it easier for the welders to mount the inlet pipes at site and to decrease the time for mounting. Another aim for the project has been to make a comparison of cost between the original design and the new design. The methodology that has been used in this thesis is the Voice of the customer table and Systematic design based on Vladimir Hubka’s design process, among others. There have also been studies of the original inlet pipe design by looking at drawings and pictures from former site mountings. Today, the original inlet pipe is shipped unassembled together with the exhaust diffuser direct from KSG AB in Surte, one of SIT AB’s subcontractors, to be mounted and welded on site. Due to the angled mounting caused by the design of the inlet pipe and the round exhaust diffuser, today’s welding must be made on an elliptic hole. This results in poor fitting of the inlet pipe and the hole and modifications have to be made to make them fit together. To find a new design for the inlet pipe, 17 concepts was created from interviews and brainstorming. Of those, nine was singled out and further evaluated by the developed criterions of the customer. This evaluation resulted in rejection of three more concepts. Last, the three maintaining concepts were compared and one final concept was selected. The new concept consists of two pipes. The upper pipe has the same inner diameter as the outer diameter of the downer pipe. This brings the opportunity for adjustments in height and angle to fit the bellow that does connect the inlet pipe with the bleed air pipe. The upper pipe has been welded on to the exhaust diffuser before it was shipped to site. To mount these two pipes together, they must be welded, even if the assemblers hoped this type of mounting would be avoided. This has been solved by designing round pipe endings. It is also most likely possible to make the design with reduced diameter, which will decrease the weight of the product. This new design will approximately decrease the mounting time on site up to 60 % in comparison with the original design. This will result in decreased installation cost. Due to the upper pipe’s need for mounting before it is shipped to site, the manufacturing cost will approximately be the same as for the original pipe. The total cost for both pipes will be decreased with approximately 45 %, compared to the original pipes. Hopefully, an interest has been generated at SIT AB by this project to make a change of the design for this component, to make the mounting easier in the future.

Texte intégralRésumé :
The stone towns of the Swahili Coast are a visible reminder of once prosperous kingdoms who had built their wealth on the Indian Ocean trade. From the 19th century onward the coins found numerously at some of these towns intrigued European travellers and scholars alike. Initially, it was believed that they were remnants, like the stone towns, of a colonial Arab or Persian culture. At first only copper coins were known, with the majority coming from stray . finds from the beaches of the eroding settlements. These copper coins had Arabic writing on them spelling out a rhyming legend which continued from one side to the other. They were ascribed to the Sultans of Kilwa, while similar coins were believed to originate in ;Zanzibar. Little though was understood regarding their origin and they were primarily seen as a means to better understand the chronology of Kilwa. It is now clear that these copper coins were preceded by minute silver coins, similar in their designs and legends to the copper coins. 'Although it is clear that the silver and copper coins are an interrelated coinage, many issues remain regarding their chronology and development. There is no detailed study that has looked at this East African coinage as whole. It is here that this thesis finds its place. In the light of new archaeological material and with the results of XRF analysis carried out on the copper coins, it investigates the issues surrounding the origin, chronology and purpose of this coinage. It tries to understand the coinage not only from the perspective of the Indian Ocean, but also in its much neglected African context.

Texte intégralRésumé :
Det svenska charterflygbolaget TUIfly Nordic AB har haft problem med att på ett korrekt sätt estimera det antal mantimmar som fordras för planerade underhållsaktiviteter på flygplanstypen Boeing 737-800. Problemen har berört tidsestimeringarna för arbetskort i flygplanstypens underhållsprogram samt tidsestimeringarna för öppning och stängning av paneler och luckor. För att söka en lösning på problemen har det här examensarbetet utvecklat metoder för att modifiera de tidsestimeringar för arbetskort, paneler och luckor som finns i TUIfly Nordics underhållsprogram för Boeing 737-800. En metod för att fastställa tidsåtgången för att åtgärda defekter, s.k. findings, som hittas på flygplanen vid utförande av arbetskort har också utvecklats. De utvecklade metoderna har använts för att beräkna nya tidsestimeringar i Microsoft Excel. De nya tidsestimeringarna som beräknats för paneler och luckor är de tidsestimeringar som tillhandahålls av flygplanstillverkaren Boeing multiplicerade med en faktor två. De nya tidsestimeringarna för majoriteten av arbetskorten är de tidsestimeringar som tillhandahålls av Boeing multiplicerade med en faktor fyra, plus ett tidstillägg för den tid det tar att åtgärda findings. Slutsatsen som kunnat dras är att de nya tidsestimeringarna innebär en förbättring av flygbolagets tidsestimeringar för arbetskort, paneler och luckor.The Swedish charter airline TUIfly Nordic AB has experienced problems determining the correct number of man-hours required to perform planned maintenance activities on the aircraft type Boeing 737-800. The problems have concerned the man-hour estimates for task cards in the aircraft type’s maintenance program and the man-hour estimates for the opening and closing of access panels. To address this problem, this thesis project has developed methods for modifying the man-hour estimates included in TUIfly Nordic’s Boeing 737-800 maintenance program related to task cards and access panels. A method for the determination of the time required to rectify findings detected when performing task cards has also been developed. The developed methods have been used to calculate new man-hour estimates in Microsoft Excel. The calculated man-hour estimates for access panels are the man-hour estimates provided by the aircraft manufacturer Boeing multiplied by a factor of two. For most task cards, the calculated man-hour estimates are the man-hour estimates provided by Boeing multiplied by a factor of four, plus an estimation of the man-hours required to rectify findings. It has been concluded that these new man-hour estimates represent an improvement of the airline’s man-hour estimates for access panels and task cards.

Os aços de alta resistência avançados estão sendo desenvolvidos e usados para a indústria automotiva devido à sua excelente combinação de alta resistência e ductilidade, acarretando na minimização de custo e peso e maximização da segurança. A soldagem por fricção e mistura mecânica a ponto (Friction Stir Spot Welding – FSSW) é uma nova variante do processo de fricção e mistura mecânica (Friction Stir Welding – FSW), que é um processo de soldagem no estado sólido, e pode ser aplicada em uma variedade de indústrias que necessitam de soldagem a ponto como a indústria aeroespacial, automotiva, nuclear, óleo e gás, transporte e outras indústrias que necessitam fazer a junção dos metais usando, geralmente, uma configuração de sobreposição. O presente trabalho é um estudo exploratório para melhor compreensão da soldagem por fricção e mistura mecânica a ponto do aço TRIP 800. Diferentes corpos de prova foram produzidos usando velocidades de rotação da ferramenta de 1600, 2000 e 2400 rpm e tempos de espera de 2s e 3s. Além da caracterização metalúrgica e determinação de microdureza, ensaios de cisalhamento e cross-tension foram realizados para avaliar o desempenho mecânico das juntas.
Advanced high strength steels (AHSS) are being developed and are being used for the automotive industry due to their exceptional combination of high strength and ductility, which leads to cost and weight savings and better safety. Friction Stir Spot Welding (FSSW) is a novel variant of Friction Stir Welding (FSW), which is a solid-state joining process without bulk melting and can be applied in a variety of industries that require spot welding such as aerospace, automotive, marine, nuclear, oil and gas, transportation industries and other industries that need to join metals together, generally using an overlap configuration. The present contribution is an exploratory study to a better understanding of a TRIP 800 friction stir spot welding. Different samples were produced using tool rotational speeds of 1600, 2000 and 2400 rpm and dwell time of 2s and 3s. Besides the metallurgical characterization and microhardness determination, lap-shear and cross-tensile tests were carried out to evaluate the mechanical performance of the joints.

Texte intégralRésumé :
The stability of Haynes 230 and Hastelloy C-276 nickel alloys exposed to high temperature molten salt with trace contaminants (i.e., water and oxygen) is found to be acceptable for using these metals to house anaerobic MgCl2-KCl and NaCl-KCl-ZnCl2 molten salts at 800oC. The corrosion rate determined by gravimetric tests range from -98 µm/year to 20. 13 µm/year at 800˚C. The corrosion rate is estimated to be 16.14 µm/year for Haynes 230 and 10.03 µm/year for Hastelloy C-276 based on the weight loss and surface area of the coupons when the coupons of Haynes 230 and Hastelloy C-276 alloys are immersed in molten MgCl2-KCl salt in sealed quartz containers and left in an oven at a temperature of 800˚C up to 16 days. The corrosion rate is estimated to be -20.46 µm/year for Haynes 230 and -7.36 µm/year for Hastelloy C-276 based on the weight loss and surface area of the coupons when the alloys are immersed in molten NaCl-KCl-ZnCl2 salt in sealed quartz containers and left in an oven at 800˚C up to 56 days. The corrosion rate of the alloys are well below the DOE requirement of 50 µm/year for the alloys in molten chloride salts to be considered acceptably stable. Ultimate tensile strength (UTS) after immersion of Haynes 230 and Hastelloy C-276 in molten salt ranged from 634 MPa to 860 MPa. The UTS of Haynes 230 is estimated to be 642 MPa after exposure to NaCl-KCl-ZnCl2 for 4 weeks at 800˚c and 841 MPa after exposure to MgCl2-KCl for 4 weeks at 800˚c compared to an untreated sample which achieved a UTS of 851 MPa. Likewise, the UTS of Hastelloy C-276 is estimated to be 692 MPa after exposure to NaCl-KCl-ZnCl2 for 4 weeks at 800˚c and 842 MPa after exposure to MgCl2-KCl for 4 weeks at 800˚c compared to an untreated sample which achieved a UTS of 830 MPa. Molten chloride salts, such as NaCl-KCl-ZnCl2 and KCl-MgCl2, are pretreated by heating and bubbling dry Argon gas in the salt in order to remove oxygen and water and thereby reduce the corrosion of metal containers of molten salt. Monitoring the relative humidity and percent oxygen of the exhaust gas during the sparging of dry Argon at 240 sccm into 150 g of molten chloride salt at 500˚C for NaCl-KCl-ZnCl2 and 700˚C for KCl-MgCl2 allows an estimation time to reach a low level of oxygen and water in the salt and to estimate the amount of oxygen and water removed. Results show water is more difficult to remove than oxygen from the salt. Ten minutes of sparging with dry argon brings oxygen content of exhuast gas to<0.1% O2. Approximately fifty minutes of sparging leaves the exhaust gas only containing<0.7% RH. The total moles of oxygen removed from the salts are estimated to be 0.0043 moles for molten NaCl-KCl-ZnCl2 and 0.0076 moles for KCl-MgCl2. The total moles of water removed from the NaCl-KCl-ZnCl2 salt is estimated to be 0.016108379 moles and 0.002321214 moles from molten KCl-MgCl2.

Texte intégralRésumé :
In this dissertation I trace the evolution of the institutions governing woodland in South China over the longue durée. I claim that after a high point of state forestry the imperial government lost both the interest and the ability to manage woodland effectively. Forestry was largely taken over by lineages - kin groups organized around the worship of shared ancestors. I tie this transition in woodland governance to two interrelated trends: growth in the power and independence of lineage organizations, and of long-distance trade in wood products. First, I show changes in local state capacities for tax collection and dispute resolution, the growing organizational capacity of lineages. Second, I argue that the growth of trade in woodland products affected state and lineage differently. On the one hand, government bureaus had increasing difficulty governing wood land while finding it increasingly convenient to obtain wood products on the market. On the other hand, lineages were well-equipped for the business of managing local landscapes, and saw substantial profits to be made from the export of timber and other forest commodities. Finally, I argue that the rise of lineage influence shaped the terms in which woodland was claimed for private use. Over hundreds of years, claims to woodland shifted from the formal legal discourse specified by the imperial state to focus on the specialized language of fengshui. By the sixteenth and seventeenth centuries, claims no longer trumpeted the productive capacity of forests or their role in paying the taxes important to the state; they now focused on the physical and metaphysical powers of the wooded landscape and its role in protecting the graves important to lineages. Contrary to existing scholarship, I claim that the decline of state forestry did not necessarily lead to the decline of the woods themselves; lineage oversight was highly effective at managing forests for both production and protection, and areas of strong lineage control remained well-forested into the modern era.East Asian Languages and Civilizations

Texte intégralRésumé :
This dissertation will examine evidence for communication and commerce between western Britain, Scotland, Ireland', their Continental and British neighbours, and the Mediterranean, in the period 400-800 AD. Parts of the terrain and subject of this enquiry have been covered in earlier, well-known studies by Heinrich Zimmer, Kuno Meyer and Joseph Vendryes, all of whom explored the evidence for 'direct' travel between Ireland and Gaul in this period, and by 0. G. S. Crawford and E. G. Bowen, who examined the early medieval evidence in wide-ranging studies of what they termed the 'western seaways'. Their sources and methods have figured more recently in studies of the 'Irish Sea Culture-Province' hypothesis4 and, most significantly, of the contacts indicated by imported ceramics identified on western British and Irish sites since the 1940s.
Despite the considerable literature arising from these previous researches, however, a separate historical study integrating archaeological and textual sources to answer the basic question of who was coming and going from the western shores of Britain and Ireland in the period 400-800 AD, and by what means, is lacking. It has to a large degree been taken for granted that maritime exchange would have constantly flourished along the western seaboard, to be invoked whenever an explanation was required for the movement of ideas or objects between regions. The studies of Zimmer and Bowen, in particular, sought to identify communication models as the background to theses concerning the spread of culture to and from early medieval Britain and Ireland. Other investigations have discussed aspects of the subject with reference to Zimmer, sometimes adding new material in the case of Crawford, James and Thomas, but in other cases, such as studies by Boissonade, Vendryes and Lewis, chiefly repeating the core of references assembled by Zimmer. Accordingly, the desire of the cultural theorists to imagine constant trading links as a background to cultural exchange has been carried over into studies of economic history where, for example, Zimmer's 'Wine trade' model, a theory particular to his thesis of the spread of classical culture to Ireland, has cast a misleading spell over most subsequent studies, both historical and archaeological, and has deflected any questioning of the causal relationship between commerce and the travels of cultural practitioners such as scholars who travel on trading ships. In some cases, for example where monastic links may be involved in the formation of commercial links, possibly crucial relationships are obscured.

La tesi riguarda la situazione storico-culturale di Carrara nel XIX
secolo; la ricerca, in particolare, indaga, al di là dell'immagine
sterotipata di questa cittadina, legata da secoli in maniera univoca
al marmo chiusa e relegata all'interno della nicchia delle sue
montagne, quali siano state le dinamiche cittadine legate alla
produzione del cosiddetto "oro bianco" durante il secolo che ha
registrato l'industrializzazione delle lavorazioni minerarie, fino ad
oggi rimaste "nascoste" rispetto all'enorme popolarità del materiale
marmo di Carrara.
La tesi è stata sviluppata, prendendo le mosse dall' origine della
città: partendo dall ' antica matrice, la colonia romana di Luni,
dalle origini del tutto leggendarie fino ad approdare alla storia
documentata, per poi focalizzarci sul cambiamento sociale che,
attraverso conflitti interni alla comunità, ha determinato l'ascesa di
importanti famiglie della borghesia del marmo (come la famiglia Del
Medico e i Fabbricotti) sulle svolte politiche ed economiche che
hanno caratterizzato la città nel corso del pieno Ottocento.
Il XIX secolo, infatti, risultò essere un secolo fondamentale per
l'avvento dell'industrializzazione nel settore lapideo, che a carrara
benficò dell'inventiva di importanti personaggi stranieri come
l'inglese William Walton e della costruzione della Ferrovia Marmifera
nel 1876 .
La tesi prosegue con la trattazione della situazione artistica-
sociale di Carrara, soffermandosi sull'avvento dei laboratori
artistici moderni i quali sostituirono le antiche botteghe e la loro
diffusione sul territorio carrarese e sul ruolo dell'artista
carrarese.
Gli artisti locali tra Ottocento e Novecento, in particolare,
superarono ogni pregiudizio del lavoro di copia (caratteristica del
XIX secolo), prevalendo in loro l'esigenza di rimanere sempre e
comunque a contatto con la materia e con l'atavico taglio della
pietra, portando parallelamente avanti anche realizzazioni di sculture
di inventiva. La Tesi si conclude con di riferimenti all'affermazione
della scuola carrarese al di fuori della Apuane, al ruolo fondamentale
che la scuola apuano-versiliese giocò in Europa e nelle Americhe a
cavallo tra il XIX e XX secolo e con la trattazione di cinque casi di diffusione artistica italiana in Francia, Gran Bretagna, Spagna, Stati
Uniti e America Latina.

Texte intégralRésumé :
This thesis comes under the terms of Clause 3.2 in the booklet Research Degrees, Regulations and Notes for Guidance for the University of North London where it is stated that 'A candidate may undertake a programme of research in which the candidate's own creative work forms, as a point of origin or reference, a significant part of the intellectual enquiry.' This work, 'shall have been undertaken as part of the registered research programme.' Furthermore, it is stated that the 'creative work shall be ... set in its relevant theoretical, historical, critical or design context.' (University of North London 1996: 6) The creative work consists of 65 poems intended for an audience of children and the critical work of the thesis is a process of research into the sources and origins of those poems. It is therefore an enquiry that seeks to uncover how a highly specific mode of literature comes to be written. It is my contention that descriptions of such a process are unsatisfactory unless they incorporate and combine the following four elements: i) an examination of how the particular self under consideration (me) was formed in a specific socioeconomic, and cultural moment; ii) an examination of how, within that moment, that self engaged with the texts made available in the institutions it occupied; iii) an explanation of how the writing involved a synthesis of experiences - of life, texts and audiences; iv) an explanation of how a writer reads his or her own writing. The first two of these elements comprise the 'historical ... context' noted above and the second two offer aspects of a 'theoretical ... context'.

Snow, Marcus. « Into the abyss : a study of the mise en abyme ». Thesis, London Metropolitan University, 2016. http://repository.londonmet.ac.uk/1106/.
Texte intégralRésumé :
As no single English study of the mise en abyme with its examples in our late-modern world has been undertaken, this thesis concerns the mise en abyme in English literature. In approximately the last third of the twentieth century, the concept has increasingly been associated with ‘postmodernism’ and the essential groundlessness of all claims to general or universal truth. In this thesis, I argue that the mise en abyme has become such a broad staple of character and narrative study that its meaning is diffuse in the extreme. First celebrated in the 1980s and 1990s, by several literary thinkers as a figure capturing the spirit of postmodernism, the eventual symptomatic dissipation of the mise en abyme in literary studies resulted from critical suggestions that the mise en abyme was after all, perhaps, bogus. It subsequently became associated with aesthetic phenomena far beyond its initial characterisation by André Gide in 1893. I argue that it has now become a trope of things wider than Gide’s initial allusion and has become a metaphor for abyssal - and abysmal - things. This thesis seeks to consider the history of the mise en abyme and to offer a contemporary account of what it might mean: it does this by uncovering the latent rhetorical figures which preceded the name ‘mise en abyme’. Formal readings of the play within the play in Hamlet and the gothic story read in The Fall of the House of Usher are both starting points to relink Gide’s idea to its, more common, metaphorical applications. Thus, metaphors of the abyss, the dark, the occulted, the uncanny and, most precisely, the ‘sinister’ are examined in this dissertation. The thesis first evaluates the theoretical inheritance of Gide’s work and then, in the second part, applies, through close reading, the meaning of Gide’s idea to recent, and representative literary examples. The thrust of the argument is that the reason many definitions, and applications, of the mise en abyme are such a source of problems, is because the mise en abyme, as an English literary phenomenon supporting the broad thesis of postmodern Gothic aesthetics, is concerned with representing abyssal metaphors. A clear delimitation of the mise en abyme is difficult whenever connotations of the abyss, the dark, the occult and the sinister are overlooked. So, this dissertation gives a circumspect view of what is designated as mise en abyme, and argues that, in late-modernity, its meaning is closest to the rhetorical figures named ekphrasis, metalepsis, and epanalepsis. This study concludes that, realistically, there is probably no such thing as the mise en abyme and instead, there are only rhetorical figures and metaphors of the sinister and of the abyss.

Texte intégralRésumé :
denna rapport har det tittats på olika sätt att viktoptimera en tvärbalk tillhörande en bottenram åt Siemens. Siemens arbetar med att skapa elgeneratorer med mycket hög effektivitet åt industrier. Dessa generatorer generar el upp till 2235 MVA. Alla beräkningar har gjorts på SGT-800 Split Skid. På SGT 800 Split Skid bottenramen sitter en tvärbalk under gasturbinen. Bottenramen får sin last från två lager, ett i turbinen och ett i kompressorn. Tvärbalken lastas via en platta och pendelstöttor på flänsen. Syftet med detta arbete har varit att titta på den tvärbalken och se ifall vikt kan sparas. Lastfallet som tittats på är en kombinationslast av gravitation och blade loss vilket innebär att ett rotorblad går av under användning. Under arbetets gång har olika optimeringar gjorts, storleks, form och topologi. Ett materialbyte har också gjorts. Optimeringen har gjorts via programmet optistruct efter att ha fått modellen i abaqus och konverterat den till optistruct. Efter materialbyte och en kombination av topologi och storleksoptimering gjorts kan 39 % av vikten sparas.This report looks at different ways to optimize a cross beam belonging to a base frame for the company Siemens. Siemens builds and analyses industry sized generators with high efficiency for industrial buyers. These generators can generate power up to 2235 MVA.All calculations have been made on the SGT-800 Split Skid model. The SGT-800 Split Skid base frame there is a crossbeam underneath the turbine. The crossbeam takes stress through a solid plate and pendulum supports on the top flange.The purpose of this report has been to see if the weight of the crossbeam can be optimized without compromising stress results. The load case used is a combination load consisting of gravity and blade loss. Blade loss is a load case where a rotor blade snaps during use.The cross beam was optimized using size, shape and topology optimization methods, and a material change was made. The optimization was done via the program optistruct after receiving a model in abaqus and converting it to optistruct. After the material change and a combination of size and topology optimization, the weight saved is 39 %.

The International Token Classification (ITC) Framework by the Blockchain Center in Frankfurt classifies 795 cryptocurrency tokens based on their economic, technological, legal and industry categorization. This work analyzes cryptocurrency data to evaluate the categorization with real-world market data. The feature space includes price, volume and market capitalization data. Additional metrics such as the moving average and the relative strengh index are added to get a more in-depth understanding of market movements. The data set is used to build supervised and unsupervised machine learning models. The prediction accuracies varied amongst labels and all remained below 90%. The technological label had the highest prediction accuracy at 88.9% using Random Forests. The economic label could be predicted with an accuracy of 81.7% using K-Nearest Neighbors. The classification using machine learning techniques is not yet accurate enough to automate the classification process. But it can be improved by adding additional features. The unsupervised clustering shows that there are more layers to the data that can be added to the ITC. The additional categories are built upon a combination of token mining, maximal supply, volume and market capitalization data. As a result we suggest that a data-driven extension of the categorization in to a token profile would allow investors and regulators to gain a deeper understanding of token performance, maturity and usage.

Texte intégralRésumé :
Nickel superalloys are used for high-temperature application in energetic and aerospace industry. They are exposed to aggressive environment at high temperatures with the interactions between fatigue and creep processes, high-temperature oxidation, corrosion and erosion. Lifetime extension of such strained parts while increasing the performance of particular machine is possible by applying protective surface coatings. The subject of this work is to investigate the fatigue failure mechanisms of superalloy Inconel 713LC at 800 °C and to compare these mechanisms between material with a protective coating based on Al-Si and material without coating. The location of initiation fatigue cracks, their propagation and the fatigue crack propagation rate in some areas were analyzed by optical microscopy, scanning electron microscopy and confocal laser scanning microscopy. Based on previous research it was found that the application of the coating AlSi has a positive effect on lifetime of alloy Inconel 713LC. These results were confirmed and estimated in the diploma thesis.

Valentin Serov (1865-1911) è stato un pittore russo realista e impressionista, ma principalmente ha avuto un ruolo importante nella ritrattistica. La sua fama emerse quando aveva appena 22 anni, con le opere Ragazza con pesche (1887) e Ragazza illuminata dal sole (1888). Per tutta la vita cercò uno stile e una tecnica che gli facesse provare gioia e che comunicasse gioia, a volte avendo sfortuna, altre volte elevando sempre di più il suo nome sia in Russia che all'estero: nel 1900 all'Expo di Parigi piacque immensamente il suo Ritratto del Granduca Pavel Aleksandrovic (1897), e poi furono famosi i grandi ritratti femminili di Sofia Botkina, delle attrici Ermolova e Fedotova e per ultimo (questa volta orientandosi verso lo Stil' Modern)- il ritratto di Ida Rubinstein, che fece molto scalpore. Dopo la sua morte molte mostre "tributo" vennero fatte in suo onore, sia a Mosca che a San Pietroburgo, e l'ultima risale appena al 2015 (ebbe un notevole successo, con grande afflusso di visitatori).

Texte intégralRésumé :
Abstract
Major water soluble ions (Cl-, NO3-, SO42-, CH3SO3-, Na+, K+, NH4+, Mg2+, Ca2+) were determined and the results interpreted from a 121 m long ice core drilled at the summit of the Lomonosovfonna dome, Svalbard. The core covers about the past 800 years. The reliability of anion chemistry for paleoenvironmental studies, and various insoluble particles were also investigated. The ice core studied in this Thesis is the first relatively deep ice core from the central Svalbard that has been analyzed and the results interpreted and published at high resolution for all major ions.
One of the clearest features of the ion profiles is anthropogenic impact. SO42- and NO3- concentrations show significant increases by the mid-20th century with slight increases already at the end of the 19th century. In addition excess Cl- and NH4+ from anthropogenic sources are detected arriving after the mid-20th century. Anthropogenically derived SO42- and NO3- have different sources on Lomonosovfonna. NO3- is correlated with NH4+ and requires interpretation in terms of both natural and anthropogenic NH4NO3 sources.
The ice core ionic load consists mostly of sea salt ions (Na+, Cl-, K+ and Mg2+). Water soluble Ca2+ are mostly terrestrial in origin. Ion balance together with the Na+/Cl- ratio shows considerable change about 1730 that is most probably due to Na2CO3 input to the ice cap before 1730. Marine biogenic CH3SO3- concentrations are high and stable during the Little Ice Age. CH3SO3- concentrations show a clear change in concentrations in 1920, that is the end of the Little Ice Age in Svalbard. Regardless of anthropogenic impact, marine biogenic SO42- is appreciable in total SO42- budget even in the 20th century.
The Laki volcanic eruption in Iceland in 1783 is identified in the ice core as a volcanic tephra layer and high SO42- concentration and acidity peaks. These show that SO42- arrived to the Lomonosovfonna ice cap 6–12 months later than insoluble tephra and the SO42- aerosol caused a drop in temperature.
The reliability of ice core ion chemistry analyses was estimated – for the first time in an ice core using two different analytical procedures on 500 adjacent samples from the same depth. Small-scale inhomogeneity in ion concentrations shows that information from ice core layers is representative of the regional environmental and suitable for paleoclimate studies.

Texte intégralRésumé :
This thesis is a comprehensive, multi-disciplinary, qualitative and quantitative appraisal of the monastic economy in late Antiquity and the period of early Islam. Based on the textual and archaeological evidence of over 1,000 monasteries in Egypt and Oriens, this thesis combines both an in-depth analysis and an overall appraisal of monastic production. It follows an internal and an external, a microlevel and an integrative approach. It considers literary texts, papyri, inscriptions, colophons and published archaeological remains, especially in Syria and Palestine. The analysis of fieldwork data, personally retrieved in Syria, Jordan and Egypt in 2002 and 2003, rounds off the archaeological point of view. This thesis conders the period until AD 800, as in many regions textual and archaeological documentation break off dramatically after ca. AD 770. The emergence of monasteries in Egypt and Oriens after ca. AD 320 provoked a change of the socio-economic profile of late Antiquity. From the fifth century, coenobia and laurae played an important role in the late antique economy. Monasteries acquired land, employed labour, became centres of production and trade. Such involvement, however, gave rise to substantial internal controversy. Having first considered monasteries as architectural units ('a working definition'; chapter I), this thesis seeks to investigate the conditions of monastic production (location, landownership etc.) in chapter II. As labour and work were controversial monastic issues, the attitudes towards labour are also examined here.
