The influence of the human facial image was surveyed and the nature of its many interpretations were examined. The role of distinctiveness was considered particularly relevant as it accounted for many of the impressions of character and identity ascribed to individuals. The notion of structural differences with respect to some selective essence of normality is especially important as it allows a wide range of complex facial types to be considered and understood in an objective manner. A software tool was developed which permitted the manipulation of facial images. Quantitative distortions of digital images were examined using perceptual and recognition memory paradigms. Seven experiments investigated the role of distinctiveness in memory for faces using synthesised caricatures. The results showed that caricatures, both photographic and line-drawing, improved recognition speed and accuracy, indicating that both veridical and distinctiveness information are coded for familiar faces in long-term memory. The impact of feature metrics on perceptual estimates of facial age was examined using 'age-caricatured' images and were found to be in relative accordance with the 'intended' computed age. Further modifying the semantics permitted the differences between individual faces to be visualised in terms of facial structure and skin texture patterns. Transformations of identity between two, or more, faces established the necessary matrices which can offer an understanding of facial expression in a categorical manner and the inherent interactions. A procedural extension allowed generation of composite images in which all features are perfectly aligned. Prototypical facial types specified in this manner enabled high-level manipulations to be made of gender and attractiveness; two experiments corroborated previously speculative material and thus gave credence to the prototype model. In summary, psychological assessment of computer-manipulated facial images demonstrated the validity of the objective techniques and highlighted particular parameters which contribute to our perception and recognition of the individual and of underlying facial types.

Over the last two decades, the study of 'repetition effects' in behavioural and Event Related Potential (E.R.P) research has originated and added to theories of memory organisation. In this series of experiments, behavioural and E.R.P correlates of human and monkey visual memory were investigated, using the repetition effect as the main index of processing, and manipulating the semantic content of the experimental stimuli. The research has a large founding in established results from lexical studies. The use of pictorial material in this series of experiments extends these results to more general visual memory functions. E.R.P recordings were taken from two monkeys trained extensively to perform a matching-to-sample picture recognition task. The waveforms generated by novel instances of highly familiar pictures were compared to those elicited by repeats. In a further study with unfamiliar pictures the repetition of items had an effect on the evoked potentials for only one of the two subjects. Two further studies were made with one monkey viewing unfamiliar and familiar face pictures. In both these studies, an early potential emerged which was more positive in response to faces than to objects. In order to investigate the importance of the semantic content of stimulus items for memory processes, human E.R.Ps generated by novel and repeated presentations of 'meaningful' and 'meaningless' pictorial images were recorded. Repetition of the meaningful (but not meaningless) pictures attenuated the N400 component associated with the first presentation of a stimulus.

The aims of this thesis are two-fold. The first is to develop computer graphics that allow quantitative manipulation of complex visual stimuli. The second is to show that such techniques have utility in the domain of perceptual psychology. There are three main sections to this thesis. The first section creates methods for performing transformations of facial appearance along particular perceptual dimensions. This work begins with 2-D image manipulations and then extends the general principles to 3-D. Effectiveness of the techniques is illustrated with plates showing transformation in age, gender and identity. The second section uses Genetic Algorithms to control the appearance of 3-D computer graphics objects and investigates methods of evolving objects that embody various consumer concepts. Computer graphic models of shampoo bottles are successfully evolved to satisfy a selection of aesthetic and perceptual characteristics. The final section returns to facial stimuli and extends the Genetic Algorithm approach to investigate aesthetic preference for 3-D facial surfaces. The study shows that individual human subjects can evolve facial surfaces based upon their own attractiveness preferences. The faces evolved are non-average and there is consistency between subjects about preferred characteristics. The three parts of this thesis have different theoretical backgrounds and literature relevant to each topic is therefore reviewed at the start of each section.

Special attention will be devoted to bacon’s works The Advancement of Learning (1605) and Novum Organum (1620). The methodological renewal advocated by Bacon will be situated in the context of exposition to the aristotelian legacy generated by the Renaissance Humanism and the Protestant Reformation. The use of Aristotelian terminology in Bacon’s thought will be presented as a source of confusion. In this sense, the baconian concept of form will be indicated as a clear-cut case of terminological confusion. Despite its terminological confusions and conceptual problems the method of induction proposed by Bacon fostered massive changes in scientific knowledge and signifintly influenced the life of society. In the addition to this, Bacon associated the advancement of knowledge with the idea of social progress. It may be objected that Bacon’s thought tends to subordinate ethics to technical knowledge, but there is no doubt that his contribution is essential for the understanding of the Industrial Revolution, the Enlightenment, The Positivism and the contemporary proposals of social engineering. / Esta dissertação tem por objetivo investigar a abordagem da relação entre conhecimento e ação política articulada por Francis Bacon (1561-1626). As obras O Progresso do Conhecimento (1605) e Novum Organum (1620) receberão especial atenção. A renovação metodológica advogada por Bacon será situada no contexto de oposição ao legado aristotélico pelo humanismo renascentista e pela reforma protestante. A utilização da terminologia aristotélica no pensamento de Bacon será apresentada como uma fonte de confusão. Neste sentido, o conceito baconiano de forma será indicado como um caso claríssimo de confusão terminológica. A despeito de suas confusões terminológicas e dos seus erros conceituais, o método indutivo proposto por Bacon fomentou gigantescas modificações na construção do saber científico e influenciou significativamente a vida da sociedade. E mais: ele associou o avanço do conhecimento com o progresso social. Pode-se objetar que o pensamento de Bacon tende a subordinar a ética à técnica, mas não se pode negar que contribuição dele é essencial para a compreensão da Revolução Industrial, do Iluminismo, do Positivismo e das propostas contemporâneas de engenharia social.

What follows is a relatively concise attempt at ordering a series of abstracted and formalized vernacular elements within a cohesive whole. A lodge and series of cabins located in Pulaski, Virginia are used as a vehicle for pursuing this exploration. / Master of Architecture

Metallurgical coke is an important component of the iron and steel industry. It is obtained from high quality coking coals like bituminous coal. However, due to the limited resources and high levels of Green house Gases, alternatives to the product are of high demand. Availability of raw materials is an important factor. The product should have high heating value, strength and lower emissions. Research is being done on form coke technology; to produce high quality substitutes with inexpensive materials like lignite. A biomass-based form coke production process is developed. Two types of raw materials are selected at beginning of process. However, an ideal choice of raw material is evaluated by comparing the quality of the specimens produced from each substance. Various stages of the process are developed and their operating conditions are evaluated. The specimens developed are sent to a test facility to test reactivity and strength after the reaction.
