The main idea is to examine the space between the body and thegarment. To higlight the inner void that is in between.By pushing lines away from the expected and recognizedpositions.I emphasize parts and make them stand out from the body.By using supporting materials my method has been to constructvolume in the garment instead of building up a contrution which is filled inside.The choice of denim as the main fabric in this collection is because of how it is affected by the body.The result is a collection of garments that both highlight and obscure the lines of the body. / Program: Modedesignutbildningen

Ce travail de thèse s’intéresse au lien possible entre le sentiment de vide psychique et les transmissions transgénérationnelles chez des sujets adultes consommant, de façon pathologique, des substances toxiques. L'analyse critique de la littérature explore les caractéristiques liées aux substances appelées « drogues » ou « toxiques » et au phénomène de dépendance. Au regard des spécificités du caractère de la dépendance, nous abordons les phénomènes de transmission dans la filiation et plus spécifiquement les éléments qui, se transmettant de façon inconsciente, sont dits transgénérationnels. La notion de « vide psychique » est alors explorée à travers la pensée d’André Green dans un lien avec les processus psychiques défaillants chez les sujets consommateurs. Nous proposons quatre études de cas cliniques - d'hommes adultes consommateurs -pour illustrer nos propos théoriques. Ces dernières se sont constituées à travers l’exploration du génosociogramme de chacun des sujets, ainsi que de l’analyse des tests projectifs. Il apparaît que l’histoire des sujets contient des éléments méconnus ou des formes de secrets à garder. De plus, la place du père et sa fonction semblent peu investies par le sujet, à l'opposé d’une figure maternelle très présente. Cette dualité relationnelle mère-enfant protège ainsi de toute séparation familiale et au-delà de toute élaboration psychique d’événements familiaux/ancestraux scellés sous le poids du silence. La substance consommée permet au sujet de venir faire rupture ou de tenter de faire rupture avec l’histoire transmise de façon négative – car non élaborée – et de créer une histoire à soi. / This thesis focuses on the possible link between the feeling of psychic emptiness and transgenerational transmissions amongst pathologically adult users of toxic substances. The critical analysis of the literature explores the characteristics related to substances named "drugs" or "toxic", as well as the phenomenon of dependency. Given the specific nature of dependency, we approach transmission phenomena in regards to filiation and more specifically to the elements which, unconsciously transmitted, are called transgenerational.The notion of "psychic void" is then explored through André Green's thought, in connection with deficient psychic processes in drug users.We propose four clinical case studies - of male adult users - to illustrate our theory.These were formed through the exploration of each subjects genosociogram and the analysis of projective tests. It is revealed that each subject's history contains unknown elements or forms of secrets to be kept. In addition, the father's place and function seem poorly invested by the subject, opposed to a very present maternal figure. This relational duality mother-child protects thus from any family related separation and, even further, from all psychic formulation of family or ancestral related events sealed by the weight of silence. The used substance allows the subject to breach or attempt to break with the negatively transmitted history - as it is not elaborated - and to create a history for himself.

Abstract Using a finite element package software DEFORMTM, this study simulated plastic deformation of the sheet at the roll-gap during sheet rolling processes. Rigid-plastic model of material is adopted. The rolls are assumed to be perfectly rigid and the sheets are isotropic. This study consists of three parts¡G(1) analysis of asymmetrical sheet rolling ; the effects of rolls speed ratios, roll radii ratios, friction factor ratios between sheet and rolls surface, upon the curvature of the rolled product and rolling force were systematically discussed. The larger the roll radius and the roll speed ratios are, the smaller the rolling force is and the larger the curvature of the sheet analytically. (2) Closing behavior, the deformation mechanism and stress-strain distributions around internal voids inside the sheet during sheet rolling was discussed numerically. The influences of various rolling conditions, such as the thickness reduction, the dimension of the internal void, friction factor, cross-sectional area of the void, etc., on the dimension of the void at the exit were discussed. The critical thickness reductions, over which the void would close completely, were also investigated. It is known that the critical reduction decreases with increasing roll radius. That is because the rolling pressure at the roll gap increases with increasing roll radius, accordingly, it takes smaller reductions to make the void closed completely. The critical thickness reduction decreases with increasing roll radius and decreasing voids dimension-thickness ratios. (3) The possibility of voids occurred at the front and back of the inclusion was investigated. The effects of various rolling conditions, such as the thickness reduction, the diameter of the inclusions, the roll diameter, friction factor, etc., on the generation and development of voids anticipated to occur in the front and rear of the inclusions were discussed. The critical thickness reductions under which void generation can be avoided were also examined. On the other hand, the effect of friction factor on between roll and sheet upon the void lengths in the front and rear of the inclusion is greater than that of friction factor on between inclusions and sheet. It is known that it decreases with increasing inclusions dimension, whereas the critical reduction decreases with decreasing roll radius. The analytical results showed a steady trend for 0.1mm< voids and inclusions dimension < 2.5mm. To verify the validity of the models, a series of experiments on the sheet rolling using aluminum (A1050, A6061) sheet as specimen were carried out. The experiments on sheet rolling with an internal void inside the sheet were conducted by micro-drill. The inclusions used ¡§SUS HSS¡¨ steel. The void length in the front of the inclusion is larger than that in the rear of the inclusion for both simulated and experimental results. The simulated results were compared with experimental results, and good agreement is found. Therefore, this numerical model using DEFORM software can offer useful knowledge for designing the pass-schedule in sheet rolling processes.

The flatbed scanner method for air void analysis of concrete is investigated through a comparison study with the standard ASTM C457 manual and Rapid Air 457 test methods. Air void parameters including air content and spacing factor are determined by image analysis of a large population of scanned samples through contrast enhancement and threshold determination procedures. It is shown that flatbed scanner method is giving comparable results to manual and Rapid Air 457 methods. Furthermore, a comparison of the air void chord length distributions obtained from the two methods of flatbed scanner and Rapid Air 457 has been implemented in this research. The effect of having different settings in the scanning process of scanner method is also investigated. Moreover, a threshold study has been performed that showed the flatbed scanner method can be employed in combination with manual and Rapid Air 457 methods as a time and cost saving strategy.

Research Doctorate - Doctor of Philosophy (PhD) / Permeability is an important property that arises in many fields of study. The ability to predict the permeability for a particular material is necessary as it affects the design of many materials handling and storage solutions. There are an abundance of equations that predict permeability for specific applications, but the underlying theory for these equations remains constant. Key factors affecting permeability that appear in many equations are the pore space, individual pore size, and pore connectivity. Many existing equations seek to quantify these factors in some form, with void ratio, particle diameter and tortuosity the most commonly used. Each of these factors is investigated throughout this thesis to further investigate their influence on permeability. These factors are investigated with specific reference to two equations; the Ergun equation and the Kozeny-Carman equation, and with specific reference to two types of materials; spherical particle mixtures and fibrous particle mixtures. Numerical simulation methods are used to build assemblies of spherical and fibrous particles. The assemblies of particles are used to extract fundamental information regarding the pore size and connectivity. The average size of the individual voids can be found as well as the average length the flowing fluid takes through the voids of the material. The use of the simulated assemblies to find material properties such as these allows for new insight into the structure of these types of packed beds. This new insight allows for an improvement in the way permeability is characterised for the materials studied in this thesis.

Air entraining admixtures (vinsol or non-vinsol) are used in concrete mixes that will be exposed to freeze-thaw cycles or sulfate attack. Entrained air is intended to improve the durability and resistance of hardened concrete to freeze-thaw cycles. However in many instances a significant loss of compressive strength has been observed in concrete mixes containing non-vinsol admixtures. Mixture forensic analysis has determined air void coalescing to be the main factor in observed low compressive strengths. The result of air void coalescing is the over design of compressive strength to account for the possible lower strengths and decreased confidence in the compressive strengths obtained during the quality control/assurance process.
