The aim of this study is to determine what can be known about the people who were able to write runes during the Viking Age. The investigation is based on the runecarvers’ own statements about themselves and their work, which is normally found in the signature or the carver formula of the inscriptions. The material comprises all carver formulas known from primarily Scandinavian Viking-age runic inscriptions, but since most of the inscriptions are found on rune-stones, there is a focus on runecarvers who worked in this material. In the study the form and content of these carver formulas are closely analyzed in different ways. It can for example be shown that the choice of verbs in a carver formula is primarily determined by chronology, which is also reflected in the geographical distribution of different verbs in the material. The study also shows that the carver formula is normally positioned finally in the text, and that the examples of other positions might be determined by the content of the rest of the inscription. In some cases the runic monument is signed by more than one name, which has been interpreted as indicating the existence of workshops. Even if this is true for parts of the material, many of the co-signed stones seem to be the products of carvers who only worked occasionally. An investigation of the personal names and the use of attributes such as patronymic, titles or bynames, shows no difference from the normal Viking-age population, which indicates that the rune-carvers were not members of a special social class. The latter part of the study deals with the relationships between the rune-carver and the sponsor of the runic monument. Special attention is paid to some local carvers in the Mälar Valley in order to determine their social status and the extent of their production of rune-stones. The study shows that some of these carvers belonged to a wealthy group of land-owners with contacts abroad, and many of them have executed about ten rune-stones, often in the vicinity of their own dwellingplace. In conjunction with this, there is also an attempt to see to what extent the writing habits of these local carvers are influenced by more productive and presumably professional carvers. This investigation leads to a re-evaluation of one of the most famous carvers in the district, Åsmund Kåresson, which also has some implications for the picture of how the rune-stone custom was introduced into central Sweden at the beginning of the 11th century.

Embedded system designers face multiple challenges in fulfilling the runtime requirements of programs. Effective scheduling of programs is required to extract as much parallelism as possible. These scheduling algorithms must also improve speedup after instruction-set extensions have occurred. Scheduling of dynamic code at run time is made more difficult when the static components of the program are scheduled inefficiently. This research aims to optimize a program’s static code at compile time. This is achieved with four algorithms designed to schedule code at the task and instruction level. Additionally, the algorithms improve scheduling using instruction set extended code on symmetrical homogeneous multiprocessor systems. Using these algorithms, we achieve speedups up to 3.86X over sequential execution for a 4-issue 2-processor system, and show better performance than recent heuristic techniques for small programs. Finally, the algorithms generate speedup values for a 64-point FFT that are similar to the test runs.

Located on one of the highly active seismic fault systems in the world, the building stock in Turkey is mainly composed of reinforced concrete frames with 4-5 stories. Due to design and construction deficiencies resulting from the use of unqualified personnel and insufficient supervision, many of these buildings lack lateral stiffness, ductility and strength. For many structures, there is a need to alleviate these deficiencies by means of some rehabilitation techniques prior to earthquakes. One approach also used very widely in Turkey is to fill some of the frame bays by cast-in-place R/C panels. The procedure appears to be very practical at first glance. It also appears to be very economical as far as the production of the panels is concerned. However, the production phase is slow, dirty, destructive and disruptive to occupants. Moreover, it requires relatively skilled personnel and special equipment. Therefore, the real life experience shows that the actual cost in practice is much higher when all other hidden costs are taken into account. The aim of this experimental study is to explore the potential of using infill walls made of custom shaped and high strength concrete blocks as a simpler and more practical alternative to cast-in-place R/C panels to increase the lateral load bearing capacity of frame structures. The effectiveness of FRCM (Fiber Reinforced Cementitous Matrix) system on damaged structures is also investigated in this study.

Le Livre Roisin est l'un des rares coutumiers français du XIIIe siècle. Il contient les coutumes de la ville de Lille, mises par écrit en 1267, puis recopiées et enrichies en 1297, en 1349 et enfin de façon continue jusqu'au XVIe siècle. Une dernière copie officielle fut faite en 1618-1619. L'analyse approfondie du plus ancien manuscrit du Livre Roisin qui nous soit parvenu, celui de 1349, révèle les secrets de son élaboration. Les nombreuses chartes, actes, arrêts et bans joints au coutumier à proprement parler durant plus de deux siècles donnent une vue d'ensemble des lois qui régissaient les Lillois du Moyen Âge. Au passage, les producteurs du recueil, les clercs de ville, ont laissé des traces de leur travail, de telle sorte qu'il est possible de dresser l'inventaire de leurs responsabilités et comprendre l'importance de ces officiers tant dans la perspective des institutions municipales médiévales que dans celle de l'historien, pour qui ils font partie de la chaîne de transmission des textes. De leur côté, les récepteurs, tout aussi discrets mais présents, se manifestent dans le détail de la procédure judiciaire que contient le document. L'utilisation qu'ils en ont faite, tantôt pratique, tantôt mémorielle surgit. Il en ressort que le recueil fût à la fois un aide-mémoire et un outil de défense de l'identité urbaine et même picarde. Enfin, le Livre Roisin est un outil privilégié pour l'étude de l'histoire de la ville, puisque sa rédaction et chacune de ses copies sont ancrées dans des événements politiques aux conséquences majeures pour la ville de Lille. / The Livre Roisin is one of the rare french customary of the XIIIth century. It contains the customs of the city of Lille, written down in 1267, then copied and expanded in 1297, 1349 and from then continuously until the XVIth century. One last manuscript copy was made in 1618-1619. Thorough analysis of the oldest manuscript of the Livre Roisin to have survived, that of 1349, reveals the secrets of its development. Numerous charter, acts, bans, and judgments that have been added to the customary for more than two centuries give an overview of the laws that governed the medieval Lillois. Incidentally, the producers of the collection, the clerks of town, have left traces of their work, so it is possible to take stock of their work and understand the importance of these officers both in view of municipal institutions and the medieval historian, for whom they are part of the chain of transmission of the texts. On the other hand, the receivers, just as discreet but nonetheless present, are evident in the detail of the proceedings contained in the document. Thus, the document was both practical and memorial. It was used as a reminder and as a powerful instrument to preserve urban and picard identities. Finally, the Livre Roisin is a tool for studying the history of the city, as his writing and each of its copies are rooted in political events with major consequences for the city of Lille.

The topic studied in this thesis is the right of public access as a legal institution. In that connection, several questions which are different from each other are raised. The thesis focuses to a great extent on the interaction between questions of a practical-legal nature and those whose character is more connected to legal theory. The point of departure of the discussion in the thesis is that some of the legal norms that are incorporated in the institution of the right of public access are customary law. Thus, the concept customary law is particularly considered, and the question of in what way the customary law can be filled with content raises special interest. A hypothesis is put forward in the thesis, which is that the right of public access constitutes part of those regulations whose purpose is that land should be used appropriately - seen from the societal perspective that land is a limited natural resource which should be used expediently, for the husbanding of resources. What is advocated in this thesis, is that in both the jurisprudential discussion about the right of public access and in the argumentation that is conducted in the practical legal application, the three subjects, the Actual User, the Canalizer and the Actual User in the Collective and their different use of the land, are separated. Further, it is advocated that the discussion as to which activities are allowed by the right of public access should be based on a consciousness that the activities can concern “everyday use” or “recreation” and that, depending on whether the activities are considered to concern the one or the other, different conclusions regarding the permissibility of the activities will be drawn. Furthermore, it is shown in the thesis that in conflicts between different means of using land, the courts seem to presume that all land is covered by the right of public access - a presumption that does not hold if the land is a part of somebody’s zone of home privacy, is needed for certain business or constitute biologically sensitive land. / I denna avhandling studeras allemansrätten som rättsinstitut. Därvid aktualiseras flera sinsemellan olikartade frågeställningar. Avhandlingen fokuserar i stor utsträckning på samspelet mellan frågor av praktisk-juridiskt slag och sådana av mer rättsteoretiskt slag. Diskussionen i avhandlingen utgår från att vissa av de i institutet allemansrätten ingående rättsliga normerna är sedvanerätt. Därför diskuteras sedvanerättsbegreppet särskilt, varvid frågan hur sedvanerätt kan fyllas med ett innehåll väcker särskilt intresse. I avhandlingen uppställs en hypotes om att allemansrätten är en del av en reglering syftande till lämplig markanvändning - sett ur den samhälleliga synvinkeln att mark är en begränsad naturresurs som bör nyttjas ändamålsenligt, för hushållning med resurser. I avhandlingen förespråkas att man i såväl den rättsvetenskapliga diskussionen om allemansrätten, som i den argumentation som förs i den praktiska rättstillämpningen, särskiljer de tre subjekten utövaren, kanalisatören och utövaren i kollektivet och deras skilda nyttjande. Vidare förespråkas att diskussionen, om vilka aktiviteter som är allemansrättsligt tillåtna, sker utifrån en medvetenhet om att aktiviteterna kan avse ”vardagsnytta” eller ”rekreation” och att, beroende av om aktiviteterna antas avse det ena eller det andra, olika slutsatser angående aktiviteternas tillåtlighet kommer att dras. Därtill visas i avhandlingen att domstolen, i konflikter mellan olika sätt att nyttja marken, tycks presumera att all mark är allemansrättsligt tillgänglig - en presumtion som bryts om marken ingår i någons hemfridszon, behövs för vissa näringar eller utgör biologiskt känslig mark.

An inspection system was required in order to eliminate the difficulties which appear during the inspection of the vehicles according to specific criteria at Turkish Custom Border in a short time and effectively. In this thesis, we performed experiments on such a system to obtain the overall performance of its inspection quality. We firstly give with reasons, why the source of beam is selected as X-ray source. The subsystems of the main system are the accelerator subsystem and detector subsystem. Their structures and working principles are studied in detail by comparing them with their alternatives. Series of experiments are carried out to verify the general performance of system in terms of radiation security and quality of images produced by the system. These experiments were classified as general scan experiment, inspection performance experiment, image quality indicator experiment, radiation safety experiment and general performance experiment. The container inspection system studied and experimented in this thesis is now used effectively in Turkish Customs Boarder, Edirne Kapikule and Edirne ipsala.

Computed tomography (CT) is a diagnostic tool already consolidated in the medical field and is now being used as a tool for something even more innovative, the generation of three-dimensional models of organs or bone structures of the patient for use in the creation of biomodels and Manufacture of customized prostheses. Biomodels are physical copies of the anatomical structures of regions or organs of the human body used for diagnosis and surgical planning. The use of tomographic images for generating 3D models has aroused great interest in the medical and bioengineering field. Besides the creation of the biomodel it is possible, through the use of the images, the generation of representative computational models, making possible the accomplishment of several simulations and biomechanical analyzes of the region or organ of interest, aiming at the manufacture of customized prostheses or orthoses. In this work is presented a methodology for the generation of three-dimensional mathematical models from CT scans in order to build, study and analyze a custom implant TMJ (Temporomandibular Joint), requested mechanically and made of titanium alloy (Ti6Al4V) by the prototyping process of type DMLS (Direct Metal Laser Sintering). Through the model created for the TMJ region, computational simulations of stresses and deformations were ... (Complete abstract click electronic access below) / Doutor
