Caputo, Barbara. "A new kernel method for object recognition:spin glass-Markov random fields." Doctoral thesis, KTH, Numerical Analysis and Computer Science, NADA, 2004. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-58.
Full textAbstract:
Recognizing objects through vision is an important part of our lives: we recognize people when we talk to them, we recognize our cup on the breakfast table, our car in a parking lot, and so on. While this task is performed with great accuracy and apparently little effort by humans, it is still unclear how this performance is achieved. Creating computer methods for automatic object recognition gives rise to challenging theoretical problems such as how to model the visual appearance of the objects or categories we want to recognize, so that the resulting algorithm will perform robustly in realistic scenarios; to this end, how to use effectively multiple cues (such as shape, color, textural properties and many others), so that the algorithm uses uses the best subset of cues in the most effective manner; how to use specific features and/or specific strategies for different classes.
The present work is devoted to the above issues. We propose to model the visual appearance of objects and visual categories via probability density functions. The model is developed on the basis of concepts and results obtained in three different research areas: computer vision, machine learning and statistical physics of spin glasses. It consists of a fully connected Markov random field with energy function derived from results of statistical physics of spin glasses. Markov random fields and spin glass energy functions are combined together via nonlinear kernel functions; we call the model Spin Glass-Markov Random Fields. Full connectivity enables to take into account the global appearance of the object, and its specific local characteristics at the same time, resulting in robustness to noise, occlusions and cluttered background. Because of properties of some classes of spin glasslike energy functions, our model allows to use easily and effectively multiple cues, and to employ class specific strategies. We show with theoretical analysis and experiments that this new model is competitive with state-of-the-art algorithms for object recognition.

Full textAbstract:
For many, a museum visit may consist of gazing at objects locked away in glass a cabinet accompanied by signs forbidding touch, and complex and often confusing text panels. But what message does this present to the visiting public? How can the public connect with museums and their collections if objects are beyond their reach? Why is handling reserved for the museum elite and not the general public? The value of touch and object handling in museums is a growing area of research, but also one that is not yet fully understood. Despite our range of senses with which we experience the world around us, museums traditionally rely on the visual as the principle means of communicating information about the past. However museums are increasingly required to prove their worth and value in society by becoming more accessible, not just in terms of audience but by opening up their stored collections, and government agenda is pushing for culture to feature in the everyday lives of the public. This research pulls apart the hierarchical nature of touch in the museum, demonstrating the benefits of a “hands-on” approach to engaging with the past, investigating the problems and limitations associated with tactile experiences, and puts forward a toolkit for tactile access to collections. It suggests that handling museum collections, not only enhances our understanding of the past, but provides memorable and valuable experiences that will remain with an individual for life.

Full textAbstract:
This installation is thematicly associated with my long term sold problems which is connected with loneliness, parting, leaving. I put the stress on the act of physical nearness which looks like a touch or contact but in fact it isn't so. Just this nearness generates inside tension. As you can see the installation is based on simple principles resulting from the abilities of a material. It is about two blocks of asphalt which spontanously produce a pressure on the glass. In this case the glass has the importance of imaginary dividing level which prevents a physical contact. A glass obstacle makes the fusion of the two asphalt blocks impossible. Despite a volatile character, asphalt will run down. The installation results from a human standard because the blocks of asphalt have a human proportion. I give the blocks a statute of beings who long for a touch but without success. The fusion is impossible.

Full textAbstract:
A turn away from language and the human mind as the dominant (or only) determinants of reality can be identified within many disciplines, including anthropology, philosophy and literature, reflecting a growing acceptance of human and non-human, living and non-living entities as real, complex and partially withdrawn agents in the world. In Object Oriented Ontology the definition of object is extended to include humans, who have no special ontological status. Timothy Morton proposes rhetoric as a means of drawing closer to other objects, of contacting the ‘strange stranger’; objects cannot be known directly, or fully, but can be explored through imaginative speculation. Drawing on Object Oriented Ontology, my project explores making - an intimate engagement between body and material - as a means of thinking the body as a (strange) object within a mesh of strange objects. Facture is documented as image and language, prompting a series of shifting, speculative questions: • Can writing be brought to making to generate new new approaches to craft production? • How might writing in response to making, or objects, be reintroduced into a making process as a form of feedback? • Can writing_making methods generate new approaches to writing (about) making and materials? • How might a combination of production, documentation and reflection be displayed as artwork/research? • Can making be seen as a means for contacting the ‘strange stranger’?

This thesis revolves around my work Desirable Objects, an installation in glass and other materials, which deals with objectification based on female and animal trophies. The topics included are those that have been crucial to my working process; craft, post-colonial studies and European hierarchical dualism, where woman and nature are seen as connected, but inferior. My motivation has been to get a better understanding of underlying power structures, and put this knowledge in relation to my own work. This process has led me to make a full body casting of my own body as a method of self-exploitation, in an attempt to expose myself to a similar power perspective. By making the dualistic connection between woman and nature, I am commenting a phenomenon that in my view has resulted in a similar exploitation of both.Åtråvärda objekt

Full textAbstract:
The content of the diploma thesis was an architectural study of a sacral building in Brno - Líšeň. The subject of the study was the elaboration of an ideological design of a sacral complex, which consisted of a church and a parish. The main operator of the whole complex will be the Salesian community, whose background is in close proximity to the area. The basic idea of the design was to design a spiritual place, which in its form conveys clear information about the use of the object and at the same time supports the development of ideas of the Salesian community. It is a structure that conveys the mission itself, not by one element, but by a set of several elements that together create a story, vision, mission. The ideological solution in this case thus becomes an equilateral triangle, which symbolizes the Father, the Son and the Holy Spirit. With its dominant vertical direction facing the sky, the object symbolically points to the spiritual path and self-realization. The given area is solved as a complex, the elements of which complement each other and thus create a harmonious whole. The design creates a space for both liturgical celebrations in the interior and exterior, which is used by the outdoor presbytery, which is complemented by residential stairs. These elements are intended to encourage residents to meet and establish friendly relations.

Full textAbstract:
The transparent qualities of glass lend to the creation of elements that suggest presence and absence. I often use glass as a surrogate for lost time or space in an object, comparable to the human prosthetic and the notion of a phantom limb. Recent objects of exploration have included broken bottles, fallen tree limbs, and a human skull. The practical knowledge I gained while working in a conservation lab has directly influenced the methodology for treating these objects of disrepair. My primary impetus is a desire to construct what has been lost during an objects existence and reveal sublime qualities. Looking for the spaces in-between things, I create sculpture and installations that transcend static objects beyond their corporeal existence, engage in the process of entropy, and negate it.

Art HistoryM.A.
A great deal of evidence exists in support of Bronze Age intra-Aegean trade, but the dynamics and material goods that made up these exchanges are still being explored. Initially, foreign glass most likely originated in Western Asia and Egypt. Recent excavations at the Minoan sites of Chryssi, Papadiokambos, and Mochlos have provided evidence of such trade on Crete. All three sites yielded glass beads that, judging by their rarity in the region, must have come from elsewhere. While glass artifacts such as those found on Minoan Crete are often assumed to be Egyptian in genesis, a Western Asian source has not been sufficiently ruled out. Based on their findspots, appearance, and our present understanding of shipping and trade in the Bronze Age Aegean, it is most likely that the beads from Chryssi, Papadiokambos, and Mochlos were manufactured in the Levant and arrived in Crete from the East.

Brown, James Michael. "Is Gloss a cue for Real-World Object Size?" Diss., Virginia Tech, 2020. http://hdl.handle.net/10919/99691.
Full textAbstract:
Two separate lines of research in object recognition are studies of materials perception and studies of real-world object size perception. Recent object size investigations of texture indicate mid-level features may cue representations of object size in the absence of object identity. However, these findings are somewhat controversial, and beyond that what mid-level features cue object size is not clear. Mid-level features have always been the focus of materials perception studies of gloss and specular highlights, but to date no research has been conducted that attempts to link findings on the perception of materials to high-level object features like real-world object size. Three separate experiments were conducted to study the relationship between perceived surface glossiness and specular highlights, and perceived real-world object size. Previous research on the relationship between perceived object size and real-world object size were replicated. A significant two-way interaction between ratings of perceived glossiness, object size, and texture was found. Follow-up analyses indicated that perceptions of gloss were present across categorical differences in real-world object size in both the object image and texture image task groups. For the normal object images, small objects were perceived as being glossier than big objects. For the texture images, big objects were perceived as being glossier than small objects. Between the conditions, small normal and small texture object images were not significantly different in perceived glossiness. Between the conditions, glossiness ratings for big texture object images were significantly greater than those for the normal big object images.Doctor of Philosophy
The goal of this project was to understand if category level perceptions of surface gloss (i.e. dull/matte surface reflectance versus shiny/glossy surface reflectance) could predict category level differences in the "actual" size of the objects in the real-world (i.e. small objects versus big objects). Previous research on the relationship between perceived object size and real-world object size were replicated. Moreover, in an experiment in which human subjects were tasked with rating the glossiness of images depicting small and large manmade of objects, category level distinctions in the average perceived glossiness of objects also extended to category level distinctions in perceived real-world object size; on average, small objects were perceived as being glossier than big objects. Similar effects were also found for synthetic textures created from the ordinary real-world object images; on average, big objects were rated as being glossier than small objects. Although categorical distinctions in perceived glossiness extended to real-world object size across image conditions, because there were no significant differences in the average perceived glossiness of small objects across the normal image and texture image conditions, the change in perceived glossiness for the big object images suggests that the texture algorithm used may not have preserved the surface reflectance characteristics of the big objects. Furthermore, statistical investigations of the pixel brightness for the stimulus images provided some evidence that the category level differences in perceived glossiness across object size and image condition may have been driven by differences in factors related to naturally occurring optical artifacts that are introduced when photographing small and big objects. Overall, results of this study are important because they indicate that the real-world spatial properties of objects may be jointly encoded with perceptions of object glossiness.

Full textAbstract:
Glass is being increasingly used as a structural material. In particular, its favourable aesthetic qualities have made it popular with modern designers. The most recent developments have seen glass being used as major structural elements such as beams and columns. From the engineering viewpoint these new applications present a series of design problems which need to be addressed before a coherent and safe design philosophy can be achieved. To date there has been much work on out-of-plane loading of glass, and in-plane loading of traditional materials is well described. However, there is little published advice on design for long term, in-plane loading of glass. In reality engineers have been borrowing design concepts from the two former areas to try and satisfy the latter. In this thesis it is demonstrated that this is not satisfactory, and a new “Crack Size Design” method is proposed. Novel contact and fracture mechanics techniques are developed in the course of this thesis, which may also be applied to more general engineering problems. Of particular interest is the evaluation of the stress intensity factors for closed edge cracks in a half plane, and a description of their growth in a bulk compressive stress field. These techniques are used in an investigation of contact loading. Contact stresses are particularly important to glass design as glass is unable to flow plastically to relieve high local stresses. Hence “soft” interlayers are often inserted between the glass and the contacting material to facilitate stress redistribution. The problem of a rigid, square-ended punch loading glass via a perfectly linear elastic or rigid plastic interlayer is analysed. The results for an edge crack under such loading conditions are then investigated and incorporated into the newly derived Crack Size Design philosophy.

Full textAbstract:
This research deals with the mechanical characterisation of thick composite laminates in the through-thickness direction. Three independent glass fibre/epoxy laminate configurations, namely cross, quasi-isotropic, and woven, plies were investigated. Six specimen configurations, of which two were developed herein, were employed in order to determine the strength behaviour of these three laminate configurations when subjected to interlaminar shear and interlaminar tensile stresses in isolation and in combination. The stress and strain distributions were estimated using the ABAQUS FEA package. The strain distribution obtained thereby was verified experimentally via Moirandeacute; interferometry which records the exact strain field at the test section. A two dimensional failure envelope is defined for each laminate configuration using the experimentally obtained data. All three independent laminate configurations exhibited almost identical failure envelopes. The woven laminate exhibited superior interlaminar shear strength when subjected to combined interlaminar shear and interlaminar tensile stresses, whereas the cross-ply laminate exhibited superior interlaminar tensile strength when subjected to the same combination of stress. The characteristics of the quasi-isotropic laminate were similar to that of the cross-ply laminate. A partial three dimensional failure envelope was also defined for the materials tested.

This thesis examines the representation of glass in French and Belgian poetry associated with the Symbolist and Decadent movements. It incorporates a number of authors, particularly focussing on Baudelaire, Mallarmé, Laforgue, Rodenbach, and Maeterlinck, but also encompassing more minor writers where appropriate, as well as some writers on the periphery of Symbolism and Decadence. The thesis investigates how the growing use of glass in architecture, technology, and visual art influenced late-nineteenth-century poets, providing these writers with a means by which to understand their social context as well as a multi-faceted metaphor through which to interrogate their own poetic mechanisms. Glass, in its various manifestations - windows, lenses, hothouses, aquariums, Exhibition halls, Art Nouveau glasswork, and stained glass - prompts meditation on such questions as: the interaction between subject and object; the relationship between fiction and reality; the infinite; poetic form; nature and artifice; and aesthetic identity. Ultimately, I combat the traditional understanding of this poetry as being solely concerned with the pure realm of dreams, the soul, and the 'Idée'. Instead, I insist on the material world as a starting point for this poetry, demonstrating that it is not immune to environmental factors, but rather that it uses its environment as a route towards the elusive 'Idée'. Glass is key to this process because its very ambiguity makes it a suitable embodiment of the tension between the material and the unknown, invisible, or ideal.

Full textAbstract:
In this thesis we derive mathematical models for the glass sheet redraw process for the production of very thin glass sheets. In the redraw process, a prefabricated glass block is fed into a furnace, where it is heated and stretched by the application of draw rollers to reduce its thickness. Redrawn sheets may be used in various applications including smartphone and battery technology. Our aims are to investigate the factors determining the final thickness profile of a glass sheet produced by this process, as well as the growth of out-of-plane deformations in the sheet during redraw. Our method is to model the glass sheet using NavierâStokes equations and free-surface conditions, and exploit small aspect ratios in the sheet to simplify and solve these equations using asymptotic expansions. We first consider a simple two-dimensional sheet to determine which physical effects should be taken into account in modelling the redraw process. Next, we derive a mathematical model for redraw of a thin threedimensional sheet. We consider the limits in which the heater zone is either short or long compared with the sheet half-width. The resulting reduced models predict the thickness profile of the redrawn sheet and the initial shape required to redraw a product of uniform thickness. We then derive mathematical models for buckling of thin viscous sheets during redraw. For buckling of a two-dimensional glass sheet due to gravity-induced compression, we predict the evolution of the centreline and investigate the early- and late-time behaviour of the system. For a three-dimensional glass sheet undergoing redraw, we use numerical solutions to investigate the behaviour of the sheet mid-surface.

Nanocomposite thin films with gold nanoparticles embedded in a host metal oxide prepared by spray pyrolysis deposition have been investigated. A single-step process has been developed using a one-pot solution containing precursors for both gold nanoparticles and host metal oxides. The films obtained display combined features of colouration, electrical conductivity and solar control. In this study two precursors for gold nanoparticles were used: preformed gold colloids and HAuCl4. Three metal oxide host materials, TiO2, SnO2 and ZnO, were investigated. These films were deposited at a substrate temperature of 200-600 °C. Powder X-ray diffraction analysis reveals the presence of metallic gold. SEM inspection typically showed particulate gold of 5-20 nm in diameter, distributed at the surface or within the host matrix. Optical spectroscopy showed an intense absorption in the visible region due to the characteristic surface plasmon resonance (SPR) effects of gold nanoparticles. The wavelength of the SPR peaks varies depending on the refractive index of surrounding host material which is significantly influenced by the substrate deposition temperature. On the other hand, SnO2 and ZnO, together with the introduction of dopants, were further investigated as suitable materials for transparent conducting oxides (TCO). SnO2:F films were found to attain very low electrical resistivity, while ZnO films exhibit higher transparency in the visible. A double layered structure with a TCO layer of SnO2:F on top of a layer embedded with gold nanoparticles has been employed to achieve the combined functionalities of conductivity and colouration. The electrical conductivity is significantly enhanced compared to a nanocomposite single layer film due to the introduction of the TCO top layer. In this thesis, spray pyrolysis deposition has demonstrated a simple and rapid approach to the production of a variety of thin films. It can be immediately integrated with current industrial coating equipment and scaled up for large-scale production process.

Full textAbstract:
In this thesis we study several different models which display glassy behaviour. Firstly, we investigate a simple, purely topological, cellular model for which the Hamiltonian is non-interacting but the dynamics are constrained. We find a non-thermodynamic transition to a glassy phase in which the energy fails to reach the equilibrium value below a characteristic temperature which is dependent on the cooling rate. This model involves activated processes and displays two-step relaxation in both the energy and the correlation functions; the latter also exhibit signs of aging. The relaxation time can be well-fitted at all temperatures by an offset Arrhenius law. Some predictions of Mode-coupling Theory are tested with some agreement found, but no convincing evidence that this description is the most fitting. By defining a suitable response function, we find that the equilibrium Fluctuation-Dissipation Theorem (FDT) is upheld for all but very short waiting-times, despite the fact that the system is not in equilibrium. This topological model is simplified to a hexagonally-based spin model, which also displays glassy behaviour, involves activated processes and exhibits two-step relaxation. This is a consequence of reaction-diffusion processes on two different time-scales, one temperature-independent and the other an exponential function of inverse temperature. We study two versions of this model, one with a single absorbing ground state, and the other with a highly degenerate ground state. These display qualitatively similar but quantitatively distinct macroscopic behaviour, and related but different microscopic behaviour. We extend this work to a square lattice, and find that the geometry of the lattice has a considerable impact on the behaviour, and to three dimensions, which provides support for the reaction-diffusion classification of the early behaviour. We find observable-dependent FDT plots; the observable can be chosen such that FDT is upheld for a region whilst the system is out of equilibrium — this observation is supported by some preliminary results for one-dimensional kinetically-constrained Ising chains.

Eren, Gönen. "3D scanning of transparent objects." Phd thesis, Université de Bourgogne, 2010. http://tel.archives-ouvertes.fr/tel-00584061.
Full textAbstract:
Many practical tasks in industry, such as automatic inspection or robot vision, often require scanning of three-dimensional shapes with non-contact techniques. However, transparent objects, such as those made of glass, still pose difficulties for classical scanning techniques. The reconstruction of surface geometry for transparent objects is complicated by the fact that light is transmitted through, refracted and in some cases reflected by the surface. Current approaches can only deal relatively well with sub-classes of objects. The algorithms are still very specific and not generally applicable. Furthermore, many techniques require considerable acquisition effort and careful calibration. This thesis proposes a new method of determining the surface shape of transparent objects. The method is based on local surface heating and thermal imaging. First, the surface of the object is heated with a laser source. A thermal image is acquired, and pixel coordinates of the heated point are calculated. Then, the 3D coordinates of the surface are computed using triangulation and the initial calibration of the system. The process is repeated by moving the transparent object to recover its surface shape. This method is called Scanning From Heating. Considering the laser beam as a point heating source and the surface of the object locally flat at the impact zone, the Scanning From Heating method is extended to obtain the surface normals of the object, in addition to the 3D world coordinates. A scanner prototype based on Scanning From Heating method has been developed during the thesis.

Full textAbstract:
The research described in this dissertation follows on from the study made by Jewell (1980)into the effects of tensile reinforcement on the mechanical behaviour of sand. For this study Jewell used the direct shear test with reinforcement placed about the central plane as shown in fig. 1.1. The direct shear test was chosen for the following reasons. (1) The reinforcement variables could be better controlled and examined in a unit cell test than in modular field studies of soil reinforcement systems. (2) The pattern of deformation is similar to that experienced by soil in which a rupture band develops, with the principal axes of stress, strain and strain increment free to rotate as is the case in model and field structures. (3) The overall shear strength of the sample is measured directly at the boundaries of the apparatus. The direct shear tests were monitored by boundary measurements and internal measurements using a radiographic technique. The findings are outlined below with reference made to relevant observations by other researchers. 1) The optimum orientation for a relatively flexible steel grid was found to be approximately along the direction of principal tensile strains in the unreinforced sand, see fig.1.2. This indicated that the reinforcement functioned by limiting tensile strains in the sand. McGown et al. (1978) obtained a similar result for plane strain cell tests on sand containing a single layer of flexible reinforcement. However in both studies the reinforcement was observed to waken the sand. Jewell recognized weakening to occur when the steel grid was placed along the direction of principal compressive strains in the unreinforced sand. This was attributed to a reduction in vertical effective stress. McGown et al. observed weakening of the sand when the reinforcement orientation approached the rupture band which developed in the sand alone. This was recognized to be the direction of zero-extension in the unreinforced sand. The weakening was linked to a lower bond between soil and reinforcement than soil alone. 2) Internal strains determined by Jewell showed the tensile reinforcement modified strains in the sand over a well defined zone, see fig.1.3. This resulted in a significant rotation of principal axes of strain increment, with the bond of major strains which developed across the centre of the box in the unreinforced sand being prohibited from forming. This agreed with boundary measurements, indicating the reinforcement functioned by limiting tensile strains in the sand. Consequently a less favourable mode of failure took place. The limit of rotation of principal axes of strain increment was understood to be the alignment of a direction of zero-extension in the sand with the reinforcement. These findings agree with the ideas expressed by Basset and Last (1978) on the mode of action of tensile reinforcement, which in particular was related to the effect of tensile reinforcement on the strain field in a reinforced earth wall as shown in fig.1.4. 3) For efficient use of tensile reinforcement it was demonstrated that the bond with sand should be as high as possible. This could be achieved by roughening the surface. Alternatively, the bond was improved by introducing openings or apertures in the reinforcement, changing the shape to a grid. It appeared that the bond for a suitably proportioned grid could be as high as for a fully roughened surface. 4) The longitudinal stiffness of tensile reinforcement was observed to affect the magnitude and rate of increase in strength in the direct shear tests. The rupture strain of tensile reinforcement relative to maximum tensile strains of the soil, under the same operational stress conditions, have also been observed to influence the reinforcing effect in terms of its limiting behaviour, i.e. whether brittle or ductile (McGown, et al. 1978). With regards to the performance of reinforced earth walls, Al-Hussanini and Perry (1976) observed that steel reinforced strips produced a stiffer and stronger structure than a more extensible fabric reinforcement, even though surface roughness was less. The importance of reinforcement tensile stiffness is recognized in limit equilibrium designs for tensile reinforced soil structures by limiting the available reinforcement force to the tensile strains that can develop in the soil (e.g. Jewell 1985). For highly structured non-woven and composite geotextiles, McGown et al. (1982) demonstrated that the stress-strain behaviour can be significantly affected by soil confinement. Testing wider strips in isolation was not found to replicate the effects of soil confinement. Another factor which needs to be considered when assessing the tensile property of a polymer reinforcement is creep. McGown et al. (1984) illustrated an appropriate method of interpreting creep data using isochronous curves, which enable long term laboratory test data to be extrapolated to the design life of the soil structure. 5) The strain and hence stress fields in the reinforced direct shear tests have been shown to be complex and non-uniform. However Jewell successfully modelled the variation of reinforcing effect for tensile reinforcement at different orientations by using a simple limit equilibrium analysis, see fig.1.5. The effect of the tensile reinforcement force was represented as: - an increase in the normal effective stress acting on the central plane of the box due to the normal component of the force and - a reduction in the applied shear stress due to the parallel component of the force to the central plane. Subsequently this analysis has been applied to limit equilibrium design methods for reinforcing soil retaining walls and embankments, Jewell et al. 1984, and Jewell 1982 respectively. 6) A reduction in the reinforcing effect for individual reinforcement due to the presence of other reinforcement was observed in the shear box. This loss of efficiency of individual reinforcement was termed interference. Interference between tensile reinforcement has also been studied by Guilloux et al.

Full textAbstract:
The stress-strain behaviour of unsaturated soils containing discrete bubbles of gas has been studied in a programme of experimental and theoretical research. The research is of particular relevance to the offshore environment, where bubbles of methane, nitrogen and carbon dioxide are formed within the seabed by the decomposition of organic matter. The presence of these gas bubbles can have a major influence on the engineering properties of the soil. As gas bubbles in marine sediments are typically much larger than the normal void spaces, the bubbles cannot be considered as simply changing the compressibility of the pore fluid. Chapters 2 to 4 describe a series of undrained triaxial tests on reconstituted samples of clayey silt from an estuarine site. Bubbles of methane were formed within the soil by using a chemical technique. The test results provide evidence of the effect of gas bubbles on the undrained shear strength, together with useful information on the stress-strain behaviour prior to failure, the generation of pore pressures during shearing, the elastic moduli and the isotropic consolidation behaviour. A theoretical model for soils containing large gas bubbles is developed in Chapter 5. The model consists of spherical bubble cavities surrounded by a matrix of saturated soil. In the following three chapters various aspects of the soil behaviour are examined by analysing the theoretical model. Chapter 6 covers the elastic moduli, Chapter 7 the consolidation behaviour and Chapter 8 the undrained shear strength. In Chapter 9 the predictions of the theoretical model are compared with the experimental results. The agreement between theory and experiment is excellent, suggesting that the theoretical approach developed and analysed in Chapters 5 to 8 is a reasonable model for the behaviour of soils containing large gas bubbles.

Full textAbstract:
The structural chemistry and magnetic properties of compounds isostructural with La18Li8Rh5O39 have been studied. In this cubic structure (space group Pm_3n), [111] chains of alternating RhO6 octahedra (2a, 8e sites) and LiO6 trigonal prisms (16i site) occupy channels within a La-O framework. In order to study the consequences of both reducing the dimensions of the channels and introducing paramagnetic cations into both the framework and the polyhedral chains, compositions in the series Nd18Li8Rh5-xFexO39 (1 ≤ x ≤ 4) have been synthesised and characterised by magnetometry, neutron diffraction and Mössbauer spectroscopy. Iron preferentially occupies the 2a site as low-spin Fe(IV) and the larger 8e site as high-spin Fe(III). Compositions having x > 1 show spin-glass-like behaviour below ~5 K. The behaviour of this series of compositions has been compared with that of the known series La18Li8Rh5-xFexO39. In order to facilitate this comparison, the structure of La18Li8Fe5O39 has been fully characterised by both neutron diffraction and EXAFS. The use of both techniques has revealed differences between the mean and local environments of iron. In order to explore and extend the range and combinations of elements that can be accommodated in this structure, the Ti-containing compounds Ln18Li8M4TiO39 (Ln=La,Nd,Pr,Sm; M=Rh,Fe,Co) have been synthesised. Nd18Li8Fe4TiO39 was selected for a detailed study by magnetometry, neutron diffraction, Mössbauer spectroscopy and XANES. Cations were found to be stabilised in unusual oxidation states and disordered over three sites of the Nd18Li8Fe4TiO39 polyhedral chains. The 8e site is occupied by high-spin Fe3+, Ti3+ and Li+ in a ratio of 76:20:4; the 2a site by low-spin Fe4+ and Ti4+ in a ratio of 79:21 and the trigonal-prismatic 16i site by Li+ and Fe3+ in a ratio of 98:2. Nd18Li8Fe4TiO39 undergoes a transition to a spin-glass state at 4.25(5) K, whereas La18Li8Fe4TiO39 revealed a different type of magnetic transition at ~8 K. The nature of this transition is not yet clear. Monophasic samples could not be prepared in the Nd/Rh system and cation vacancies were found in Nd/Co. No pure samples of Sm-containing compositions could be prepared, while the only Pr composition which was obtained pure, according to X-ray diffraction, Pr18Li8Co4TiO 39 shows the similar magnetic properties to Pr18Li8Co3TiO39. The compositions Ln18Li8M3 M'O39 (Ln=La,Nd,Pr,Sm; M,M'=Fe,Co,Ti) with 25% of the 8e sites vacant have been investigated. The Co-containing compositions Nd18Li8Co3FeO39-y, Nd18Li8CoFe3O39-y and Nd18Li8Co3TiO39-y were characterised by neutron diffraction. Cation vacancies on the 8e sites were found to coexist with anion vacancies around the 2a sites. The remaining octahedral sites are occupied by a disordered arrangement of transition-metal cations. The trigonal-prismatic sites are fully occupied by Li except in the case of Nd18Li8CoFe3O39-y where some Fe is present, as confirmed by Mössbauer spectral data. Antiferromagnetic interactions are present on the Nd sublattice in each composition, but a spin glass forms below 5 K when a high concentration of spins is also present on the octahedral sites. The magnetic character of the Ln cations plays an important role in determining the properties of these compounds. Long-range magnetic order of the transition-metal cations was not observed in any compositions. Although this might be partly attributable to the cation disorder in the polyhedral chains, the apparent antiferromagnetic behaviour of Nd-containing compositions in which the transition metals have a low magnetic moment, e.g. Nd18Li8Co3TiO39-y, and the marked contrast between certain La and Nd compositions in which the transition metal content is the same, e.g. Nd18Li8Fe4TiO39 and La18Li8Fe4TiO39, suggests that the Ln sublattice is fully involved in determining the magnetic behaviour.

Full textAbstract:
Parmi la grande diversité des productions de verres anciens appartenant aux collections muséales (vaisselle, vitres, vitraux, bijoux, perles, incrustations, statuettes, mosaïques, émaux, céramiques glaçurées…), une proportion importante montre à leur surface les signes sévères d’une altération atmosphérique (présence de sels alcalins, fracturation) conduisant à une perte de transparence voire une perte irréversible de matière. Ces œuvres sont produites essentiellement à partir du Moyen-Âge (XIIe-XIIIe siècle), avec une forte représentation aux XVIe, XVIIe et XVIIIe siècles. Les verriers ont en effet appliqué alors de nouvelles recettes par rapport à celles des périodes anciennes conduisant à une instabilité chimique du verre vis-à-vis de l’humidité ambiante. Quant aux œuvres actuellement en bon état de conservation, elles sont également susceptibles de se dégrader au cours du temps, selon leur composition et leur condition de conservation. À ce jour, le meilleur moyen de protection mis en œuvre par les conservateurs et les restaurateurs pour ralentir sensiblement cette altération est le contrôle de la température et de l’humidité de l’environnement de conservation (vitrines d’exposition spécifiques, réserves de musée). Cependant, afin de préserver cet important patrimoine culturel, il est d’un intérêt majeur de proposer de nouvelles solutions de protection qui soient à la fois plus efficaces et moins coûteuses pour les musées. C’est dans ce contexte que s’inscrit le présent projet de thèse. Il vise d’une part à faire progresser la compréhension des mécanismes d’altération atmosphérique des verres d’oxyde, d’autre part à mettre au point un traitement de protection à base de sels de zinc adapté au contexte muséal. En s’inspirant de procédés industriels qui exploitent de manière empirique l’effet protecteur des ions zinc (stockage et transport du verre plat, produits de lavage du verre en lave-vaisselle), nous avons en effet d’ores-et-déjà mis en évidence le fort potentiel de très faibles quantités de sels de zinc pour réduire efficacement les cinétiques d’altérations de compositions verrières altérables du patrimoineIn the cultural heritage field, it is of major concern to develop new protective methods for ancient glass objects that decay under atmosphere. In this framework, two complementary research directions are undertaken. The first one aims to get a better understanding of the glass atmospheric alteration mechanisms at a small scale. The second one is focused on the potentiality of a zinc salt surface treatment. By the mean of accelerated ageing experiments (temperature and humidity control) of replica glasses (alkali silicates), untreated or zinc salts treated, the evolution of the glass surface and sub-surface with atmospheric alteration are evaluated at different scales (macro – nano). These surface modifications are compared to the properties of hydrated layers of ancient glass objects that have been altered over decades. The influence of the ageing temperature and the glass composition on the atmospheric alteration mechanisms are highlighted. In particular, these parameters affect the proportion of alkali elements that are retained into the hydrated layer, which would severely impact the glass chemical durability. Positive effect of a zinc salt treatment to reduce the replica glasses hydration kinetics is shown with ageing experiments at 80 °C or 40 °C, when the glass surfaces are not pre-altered before the deposit. The formation of thermally activated zinc species that react with the glass surface are put in evidence as well as their predominant role in the protection mechanisms. Therefore, a zinc salt treatment might be considered if a heating step of the glass object is accepted (around 60 °C). However, the treatment performances seem to be strongly dependent on the surface alteration degree before the deposit. This point is critical for the relevance of the treatment for the glass artwork conservation and should be investigated deeper. Others directions of research are arisen in this work and should be followed to propose new protective methods in the longer terms

Everyday objects inspire and inform what I do. The personal histories and associations we may have with ordinary things are of great personal interest to me. Often times, these items reflect the social class, education, and background of the owners. I am drawn to these objects and the possibility of elevating them in a way that transcends their implied meanings (their worth, importance, and status). The transformation of the mundane is a method of working that allows associations to remain intact while bringing new meaning and perspective to the object. My method of working becomes an alchemic process aimed at turning the ordinary into "art" which is second only to turning used cooking oil into fuel to run your car, and maybe third to turning lead into gold.

Full textAbstract:
ABSTRACT – The use of Artificial Cover Objects (ACOs) for inventorying and monitoring of reptile diversity has become increasingly common, though few studies have investigated how occurrence and sampling success (encounters per ACO per day) varies with environmental factors when using ACOs. This study is based on data from Sandsjöbacka ecoduct and its surroundings in southwestern Sweden, where there is an ongoing monitoring program. Sixty-five plywood coverboards the first year and 15 more the next year were placed in a system of points along transects and checked 22 times (1595 shelter checks) between the year 2017 and 2018. These counts were combined with vegetation analyses and complemented with data of ambient temperature from SMHI, the Swedish Meteorological and Hydrological Institute. A total of 129 reptiles belonging to six species was found: grass snake (Natrix natrix), smooth snake (Coronella austriaca), sand lizard (Lacerta agilis), viviparous lizard (Zootoca vivipara), slowworm (Anguis fragilis) and adder (Vipera berus). There was no correlation between temperature and sampling success. DFA revealed a significant discrimination between ACOs with and without reptiles, and two of eight vegetation variables, proportion of shrubs and proportion of bare ground, were best at separating the two groups. Bare ground tended to have a negative effect on reptile occurrence, while the tendency for shrubs was the opposite. Most observations (81% of all reptiles) and encounter rates (0.065 counts per ACO per day versus 0.081 totally) were associated with slow worm (European glass lizard), and therefore the data mainly reflect activity of this species.SAMMANFATTNING – Användandet av Artificial Cover Objects (ACOs) för att inventera och övervaka bestånd av kräldjur har blivit allt vanligare, men få studier har undersökt hur förekomst och stickprovsframgång (observationer per ACO per dag) varierar beroende av biotiska och abiotiska faktorer vid användandet av ACOs. Jag fick tillgång till data från ett pågående miljöuppföljningsprogram vid och i närområden kring Sandsjöbacka ekodukt i Västra Götalands län där ACOs användes. Sextiofem inventeringsplattor av plywood första året följt av ytterligare 15 plattor nästkommande år lades ut i ett system av punkter i linjetransekter där kontroller av kräldjursförekomst skedde systematiskt under 22 inventeringstillfällen fördelade på år 2017 och 2018 (1595 kontroller av ACO) i kombination med vegetationsanalyser. Data från programmet har kompletterats med lufttemperaturdata från SMHI. 129 individer av sex arter observerades; snok (Natrix natrix), hasselsnok (Coronella austriaca), sandödla (Lacerta agilis), skogsödla (Zootoca vivipara), kopparödla (Anguis fragilis) och huggorm (Vipera berus). Det fanns inget signifikant samband mellan lufttemperatur och stickprovsframgång. DFA visade på en signifikant diskriminering mellan ACOs med och utan kräldjur, och två av åtta vegetationsvariabler, andel buskar och ris samt andel barmark, diskriminerades mest. Barmark tenderade ha en negativ effekt på förekomst av kräldjur, medan tendensen för buskar och ris var den motsatta. Klart högst förekomst (81% av totala antalet kräldjur) och stickprovsframgång (0,065 observationer per platta per dag mot 0,081 sammantaget) stod kopparödla för, och därför speglar data först och främst aktivitet hos denna art.

Full textAbstract:
This thesis is a response to a lacuna in musicology, namely the near absence of postcolonial and decolonial epistemologies. Employing both diachronic and synchronic perspectives, it provides a historical overview of the institutional positioning of musicology as an academic discipline founded on structures of expectation and exploitation indebted to Western imperialism. This longer historical view is accompanied throughout by an examination of ethics in its institutionalised forms, specifically in the domains of knowledge production and the university. The thesis maintains that while such ostensibly ethical underpinnings may promise redress on the basis of the violence inflicted by an imperialist past, the discourse employed in its application in fact serves to strengthen the ideological hold of Western hegemony and, in so doing, betrays the promise of reparation that ethics is ordinarily understood to encompass. The thesis examines different aesthetic and epistemological manifestations of the postcolonial, considering at length Steve Reich's string quartet, Different Trains (1988), Philip Glass's opera, Waiting for the Barbarians (2005), and Philip Miller's choral work, REwind: A Cantata for Voice, Tape and Testimony (2006). Both content and style weave these works together as they engage, by means of a post-minimalist aesthetic, stream-of-violence narratives intimately bound up with the postcolonial condition. Of particular importance in the consideration of these musical texts is the urgent necessity for epistemological transformation, marked in musicology as the lack of post- and decolonial perspectives. Finally, the thesis grapples with the (im)possibility of complicit scholarship that must, through its very expression, wound its subject.

The topic of this diploma thesis is design processing of a new sacral building in Brno-Líšeň district. It is a plot in the middle of a panel building between the health centre building and the building of the Salesian Youth Center, so-called Salesko. The Salesian community, which will use the building the most, has been waiting for the realization of this building for many years. The key theme is the creation of spaces enabling people to meet for worship, celebrations and social events. The design is processed by two interconnected operations - the building of the Church of the Descent of the Holy Spirit and the building of clergy house. The basic composition consists of three cubic masses - the entrance, the main liturgical space and the clergy house. The bell tower is the height dominant feature which indicates the sacral function of the building. The project consists a set of buildings with two above-ground floors and a basement in the entrance part of the church. This project also mentions the solution of open spaces around the plot and their conversion into quality public areas, marginally. The sacral space is to become a place that welcomes and takes in its visitors and gives them the feeling of safety. Inside this building, people will find peace, support and undestarstanding, so they may leave with the feeling of being a better person.

Full textAbstract:
This thesis asks how the curatorial framing of medieval objects - the processes of selection, classification, display and interpretation - affect how medieval objects are made legible within the museum. It investigates how different collectors and curators have deployed medieval objects over a period of two hundred and fifty years of museological practice. Throughout this history, medieval objects have been appropriated within a range of museological narratives that have positioned them variously as objects of curiosity, utility, scientific analysis, nationalistic interest and as sites of scholarly and popular attention. My purpose is to inquire how the epistemological re-positioning of objects is articulated through their presentation within the framework of the collection, museum or temporary exhibition and to question how the mechanics of display facilitate particular readings of medieval objects. I then consider how certain curatorial approaches may produce unintended effects that render the medieval object illegible or problematic in unexpected ways. I also acknowledge that unforeseen exhibitionary outcomes may not be solely due to the effects of curatorial intervention but may be wrought by the agency of objects themselves. This thesis therefore examines medieval objects as active participants that play a crucial role in influencing the communication of curatorial objectives and in affecting how they may be apprehended through exhibitionary practice. The thesis examines sixteen chronologically presented case studies, beginning in the mid eighteenth century and concluding in the early twenty-first century, that represent important or influential episodes in the history of the display of medieval art. It traces a selective history of the various ways medieval objects have been culturally positioned at particular points in time to reveal how curatorial techniques have worked to reinforce or undermine the perception of medieval objects as carriers of specific meanings. Through the examination of historical approaches to the display of medieval objects I reveal how familiar tropes of display, such as the use of specific lighting techniques and stained glass have characterized the museological staging of medieval objects and how these have endured into the twenty-first century. Drawing on performance theory, material culture theory and sensory theory I identify how the biographical histories, material characteristics and sensory properties of medieval objects have been re-activated or suppressed by curators to encourage audiences to engage with them in specific ways. This theoretical approach reveals a previously unacknowledged sensory cultural history of engagement with the medieval object and highlights how historical approaches that have privileged embodied engagement with objects continue to inform contemporary museological practice. I also draw on Actor-Network theory to illuminate how medieval objects may be understood as active agents within the chain of correspondences that links people, objects and exhibitions at particular points throughout this history. In this way I delineate an exhibitionary landscape through which we can understand medieval objects as multi-authored and polysemic entities but principally as the products of exhibitionary practice.

Medieval glasses have for long been a neglected object group in archeological research in Sweden. With that in mind I choose to write about those in my essay. The aim of this paper is to bring the medieval glasses into the archaeological research. I intend to show where you can find medieval glass in Sweden and what kind of glasses have been made. I will also discuss why the archeological research is so limited when it comes to the medieval drinking glasses. The archeological sites for my analysis are Sigtuna, Stockholm, Lödöse and Skanör. My theoretical approach is Material agency and I have looked at what role the drinking glasses could have had during the medieval period. I think my essay will show that you can find medieval glasses in trade or exchange contexts and that the medieval glasses absence in the archeological research has more to do with that previous research is poor rather than that glasses do not exist in the medieval period.Gamla Uppsala - framväxten av ett mytiskt centrum

Les travaux présentés dans ce mémoire portent sur l’étude et le développement d’une méthode de mesure d’épaisseur et de reconstruction 3D d’objets en verre creux, dans le cadre d’une application de contrôle industriel sur ligne de production. Les techniques de mesure d’épaisseur de parois transparentes sont actuellement très limitées par leur faible tolérance angulaire sur l’orientation des surfaces. Elles nécessitent une rotation de l’article devant le capteur, donc une manutention contraignante. De plus, les surfaces considérées étant spéculaires, les techniques de numérisation standard ne fonctionnent pas. Nous avons développé deux méthodes basées sur l’observation des réflexions d’une source diffuse ponctuelle sur les deux surfaces de la paroi de l’objet. Une observation simple à l’aide d’une caméra implique une ambiguïté entre l’orientation et la position de chacune des deux surfaces. Notre première méthode consiste à utiliser des informations de polarisation pour lever cette ambiguïté. Des résultats expérimentaux, obtenus avec un ou plusieurs points source témoignent de la faisabilité de la mesure. La seconde méthode consiste à utiliser une seconde caméra, associée à un dispositif optique spécifique. Ceci permet de trianguler directement les points d’incidence sur les deux surfaces. De plus, la source peut être étendue verticalement, de manière à augmenter la taille de la zone inspectée. Les résultats obtenus avec cette seconde technique attestent de la possibilité d’une mise en oeuvre industrielleThe work presented in this thesis focuses on the study and development of a method for measuringthe thickness and reconstructing the 3D shape of glass containers, within the frame of an industrialon-line quality monitoring. Measuring thickness techniques of transparent objects are currently limited by their lack of toleranceregarding the surface orientation at a given reflection point. A rotation of the article in front ofthe sensor is thus required, which adds complexity to the mechanical handling of the item beingmeasured. Moreover, conventional scanning techniques do not work well on specular surfaces.We developed two methods based on the observation of the reflections by both surfaces of the wallof a given item of a diffuse, point light source. Imaging these reflections with a plain camera leavesan ambiguity between the orientation and position of each surface. Our first approach uses light polarization to remove this ambiguity. Experimental results, obtainedwith one or several point sources have demonstrated the feasibility of the measure. The second approach uses a second camera, associated with a specific optical design, whichenables a mere triangulation of the incident points on the two surfaces. Moreover, the light sourcecan be vertically extended to increase the size of the inspected area. The results obtained with thissecond technique show that industrial implementation is feasible

Four different case of study are investigated: production technology and replication of lead antimonate yellow glass from New Kingdom Egypt and the Roman Empire, technology of production of polychrome lustre, analyses of Syrian lustre pottery (12th–14th centuries AD) and study of color and dichroism of silver stained glasses. These different coloured glazes or glasses have in common to be produced by the presence of micro or nanoparticles embedded into the glaze which give their special optical effect. Chemical and microstructural analyses are performed using a selection of complementary Microscopic and Spectroscopic techniques that are the most adequate for the analyses of each decoration. Physical optical properties are also modeled and measured by means of UV-Vis spectroscopy. The composition and structure of the different phases formed during the processing of the decorations in historical times is obtained with the object to learn about their stability and processing conditions and to relate them to their optical properties

Full textAbstract:
Le corpus d’œuvres et la synthèse des études menées sur les images de dévotion à l’époque médiévale n’ont jamais approfondi, dans le contexte européen, la question des peintures mariales ayant fonction de porte-reliques. Le modèle de tableau-reliquaire : panneau unique, diptyque et triptyque comprenant le portrait de la Vierge à l’Enfant peint sur bois (plus rarement sur verre églomisé) enchâssé dans un large cadre incrusté de reliques (parfois de pierres précieuses) se répandit particulièrement sur le territoire de la Petite-Pologne à partir des environs de 1420. Les reliquaires polonais, connus jusqu’au début du XVIe siècle, doivent sans doute être considérés comme une adaptation des types iconiques et formels de provenance byzantine, lesquels furent réinterprétés dans la peinture du Trecento italien. Il s’agit notamment du modèle siennois de retable portatif marial popularisé dès les années 1330-1340. D’après l’étude comparative des œuvres, relative à leurs caractéristiques similaires et leur ancienneté, on envisage l’arrivée d’un tel concept formel en Pologne soit directement de l’Italie, soit par l’intermédiaire de la Bohême.L’expansion des tableaux-reliquaires, typiques de l’art toscan, s’inscrivit au XVe siècle en Europe centrale dans le mouvement général du renouveau de piété, qu’était la devotio moderna. De sorte qu’à côté des représentations singulières, spécialement vénérées au cours des offices liturgiques et paraliturgiques, on voit se répandre des reliquaires moins coûteux dans l’espace privé. Appréciés dans l’intimité des couvents – franciscains et dominicains –, ainsi que dans celle du quotidien des laïcs, ils étaient utilisés comme des autels domestiques ou bien comme des autels pliables de voyage. Ces images d’affection religieuse constituent un phénomène artistique du bas Moyen Âge. Et, quelques-uns des reliquaires semblables connus postérieurement n’assurent pas une véritable continuité de l’ancien modèle à l’époque moderneScholarly investigation of devotional images from the medieval period has never explored, in a European context, the question of Marian paintings functioning as portable relics. The model of the « picture-reliquary » : a single, diptych, or triptych panel comprsing the por-trait of the Virgin and Child painted on wood (or, more rarely, on gilded glass, verre églomisé) set in a large framework encrusted with relics (occasionally with precious stones) was particularly widespread in the territory of Little Poland from c. 1420. Polish reliquaries, known until the beginning of the 16th century, should be considered as an adaptation of iconic types and forms of Byzantine provenance, which were reinterpreted in the painting of the Italian Trecento. Of particular note is the Siennese model of the portable Marian altar piece made popular from the 1330s-40s. From the comparative study of the works, concerning their similarities and their antiquity, one envisages the advent of such a formal concept in Poland either directly from Italy, or by the intermediary of Bohemia.The diffusion of picture-reliquaries, typical of Tuscan art, forms part of the general movement toward a renewal of piety in central Europe in the 15th century, the devotio moderna. As a result, alongside singular representations, especially venerated in the course of liturgical or paraliturgical offices, one sees less costly reliquaries spread in private space. Appreciated in the intimate setting of convents – Franciscan and Dominican – as well as that of the daily life of the laity, these relics were used as domestic altars or as folding altars for travel. These images of religious affection constitute an artistic phenomenon of the late Middle Ages. And, several similar reliquaries known later do not guarantee a veritable continuity of the ancient model to the modern era
Die erhaltenen Überblicksdarstellungen und Spezialuntersuchungen zu den Frömmigkeitsbildern des Mittelalters haben sich niemals – im europäischen Kontext – mit der Frage derjenigen Mariendarstellungen auseinandergesetzt, die die Funktion von Tragereliquien inne hatten. Das Modell des Reliquien-Bildes – einfaches Tafel-bild, Diptychon oder Triptychon mit einer Darstellung der Jungfrau mit dem Kind, gemalt auf Holz (seltener auf Glas), umschlossen von einem breiten Rahmen, in den Reliquien (mitunter auch Edelsteine) eingefügt sind – verbreitet sich ca. ab 1420 ins-besondere auf dem Gebiet Kleinpolens. Diese polnischen Reliquiare, bekannt bis zum Beginn des 16. Jahrhunderts, können ohne Zweifel als Adaptation ikonischer und formaler Typen byzantinischer Provenienz angesehen werden, die in der Malerei des italienischen Trecento wiederinterpretiert wurden. Dabei handelt es sich vor allem um das Sieneser Model des marianischen Tragaltars, verbreitet seit den Jahren 1330-1340. Folgt man den vergleichenden Untersuchungen der erhaltenen Stücke mit Blick auf ihre übereinstimmenden Charakteristika und ihr Alter, wird das Auf-greifen eines solchen formalen Konzepts in Polen entweder direkt aus Italien oder indirekt über Böhmen wahrscheinlich.Die Ausbreitung dieser Tafel-Reliquiare, typisch für die toskanische Kunst, verbindet sich im 15. Jahrhundert in Mitteleuropa mit der umfassenden Bewegung einer Er-neuerung der Frömmigkeit, bekannt auch unter dem Namen devotio moderna. Dies führt dazu, daß neben einzelnen, vor allem im Rahmen liturgischer oder paraliturgi-scher Veranstaltungen verehrten Darstellungen, zunehmend weniger kostspielige Reliquiare auch in den privaten Raum vordringen. Gehütet sowohl in der Intimität der Klöster – franziskanisch und dominikanisch – als auch im täglichen Lebensraum der Laien, wurden sie als Hausaltäre oder auch als zusammenklappbare Reisealtäre verwendet. Diese Darstellungen religiösen Affekts stellen ein künstlerisches Phäno-men des Spätmittelalters dar. Einige der ähnlichen, allerdings später entstandenen Reliquiare garantieren allerdings keine überzeugende Kontinuität vom alten Modell hin zur Neuzeit

Abstract Before a solution can be found for a specific problem, the problem has to be analyzed to determine what the root cause of the problem is. This analysis would result in focusing on a correct solution for the real problem. In my past experience, I have found lots of simple problems have not been solved due to the wrong solution. People tend to hurry to get to a solution without knowing the true nature of what the problem is. So, I invented a process called, Object Effects Analysis, OEA to use in this thesis. I used OEA to break down the problem of process and to understand how each part of the process affects the other. This can then result in focusing on a solution or solutions. OEA is a tool that was derived from the concepts of Job Safety Analysis, JSA. The main purpose of OEA is to analyze the process for the problem. This analysis is used especially for problems that reoccur repeatedly. This method breaks down the process into individual steps, this being the initiative object and passive object. It is then possible to understand the effects of these objects to each other during the action step. It is then easier to understand the root cause of the problem by using OEA to analyze the effects of the objects during process. Then we use Advanced Systematic Inventive Thinking, ASIT tool to devise a good solution. Like most production lines, the manufacture of glass in a production line depends on an operation process consisting of steps repeated within standard operation procedures. If something goes wrong during production, then this break in the cycle of production is caused by some action. I have found that use of OEA in production line problems has helped to analyze what the problem is and what has caused the problem (effects of the object). Normally the root cause of the problem is from the object or the process and the correct solution is to change the object or the process. Keywords: Objects Effects Analysis (OEA), Job Safety Analysis (JSA), Six Sigma, Advanced Systematic Inventive Thinking (ASIT)

The purpose of this study is to analyze the object relations of the characters of The Glass Menagerie, and to explore the complexity of feelings of all the characters to know how the relations influence the main characters’ family from the perspective of object relations theory. This study will analyze the characters’ behaviors and their dialogues from each character’s viewpoints, and contrast the similarities and differences between characters’ inner worlds and outer world of reality. This study explores the characters’ object relations by Melanie Klein’s and Donald W. Winnicott's theories, and refers to Williams' memoirs, letters and essays as supplementary materials. The Glass Menagerie is a memory play, and the character Tom is the narrator who leads the audience into his memories. Therefore, this study will first analyze Tom’s object relations to know the causes and effects of Tom’s runaway, then analyze his mother Amanda, sister Laura, and colleague Jim’s object relations. Finally, this study will summarize the four characters’ object relations as the conclusion.

Some UHF RFID tag antenna designs are proposed to apply for marine vehicle in this thesis. Due to loading effects to make impedance mismatching between antenna and microchip, tag antenna may not properly function when it’s attached on different material. This study first proposes an F-shaped dipole antenna attached on glass. By introducing two parasitic strips inset along the closed loop of the input IC chip to generate coupling capacitance, a new resonant mode close to the first operating mode of the regular F-shaped dipole antenna is excited to enhance the operating bandwidth. The operating frequency range can be 857 ~ 960 MHz to obtain the bandwidth of 103 MHz for UHF band with the maximum reading range of 5 m. Due to glass film with metal material, this will cause interference and degradation for electromagnetic wave. To overcome the above problem, we propose a symmetrical dipole antenna with the shorting pins connected with the ground plane. Two resonant modes can be excited to obtain the operating frequency range of 860 ~ 965 MHz to meet the specifications of UHF RFID system. Details of the proposed UHF RFID tag antenna designs are described, and experimental results for the obtained broadband performance operated at 900 MHz band are presented and discussed.

Full textAbstract:
Early Modern glass from the Iberian Peninsula has - so far - seldom been investigated. The project, combining chemical analysis with a stylistic approach, and focusing on composition and technology, aims to characterise glass objects circulating in the national territory, in an attempt to identify their origins and to eventually bring to light a Portuguese centre of glass production.
The chemical composition of more than 200 glass fragments was determined by means of μ-PIXE down to a level of tens of μg/g. The results obtained allowed one to select some objects to further extend the analysis to the trace and rare earth elements (REE) down to the ng/g level, through the use of LA-ICP-MS. Glass colours and natural hues were studied by means of UV-Vis reflectance spectroscopy and, when necessary, enamels were studied by means of μ-EDXRF and μ- Raman microscopy.
From all the objects analysed, it was possible to conclude that the great majority of the glass dating upto the 17th century, is of a soda-lime-silica type, which indicates a Mediterranean tradition. Venetian or façon-de-Venise shapes were identified, and for some of them a Venetian provenance was confirmed. For other façon-de-Venise shapes, the composition presented differences that led to the conclusion that new façon-de-Venise production centres could be recognised. From the only assemblage containing glass fragments dated to the medieval period, it was possible to attest the
presence of Venetian glass in the Portuguese territory from at least the 14th century.
Additional objects showed particular compositional features, such as high and very high alumina contents for instance, that, as far as it is known, do not match up with any of the known glass production centres in Europe. Allying the stylistic characteristics with the glass chemical composition, allowed one to identify some objects possibly belonging to a Portuguese production.
Several glass fragments belonging to wine bottles were retrieved from archaeological excavations in Lisbon and were chemically characterised. The chemical analysis revealed an HLLA composition for all of them. For some of these fragments it was possible to propose an English provenance. Besides the chemical characterisation, a systematic analysis of the bottle shape was proposed since the shape can be an important factor in determining its chronology.
A small percentage of the fragments were identified chemically as having mixed-alkali compositions, potassium-rich glass, and lead glass compositions. The latter two chemical formulations were found among the assemblages from Lisbon and the objects with these compositions were dated to the 18th century. These constitute evidence that Portugal followed European tendencies in their glass and its compositions.
This is the first systematic chemical characterisation of Early Modern glass circulating in Portugal, providing new insights into trade between Portugal and its trade allies.
As a part of the study, and to prolong the survival of these glass assemblages, simple and low cost optical sensors were developed for the in situ detection of the organic pollutant formic acid, which is emitted by materials usually used in storage and in the display of glass. The detection of the presence of this acid can play an important role in the preservation of this valuable heritage; glass.
