Today, the impact of information technologies on education field is ever more clarified with the integration of new tools and methods to the education. Education has been becoming away from the traditional classroom environment through virtual environment. Besides education of theoretical disciplines, education of practice based disciplines, like design related disciplines are moving toward virtual environments. One of these is Industrial Design (ID) education which also has made the transition to the virtual world. This thesis aims to explore and scrutinize the latest forms of ID education, especially the online distance ID education. In order to comprehend the technological progress of ID education and its possible future, an overview of the origins and an evaluation of the current state of distance online ID education are made. By this study, it is expected to shed light to the design educators and the educational systems&rsquo / developers, for designing these environments. At the end of this research, it is concluded that it is not possible to imagine a future of ID education without technology integration. However, it would be better to apply both technological and traditional methods. In fact, the key people in the development of these educational systems and tools would be the designers themselves.

This study aims to analyze how industrial design as a profession and discipline has been presented to the public in Turkey. The object of the study is constituted by the popular home style magazines which increased rapidly in number through the dynamics of the post-1980 period. These publications have been inspected in the scope of the research and their in constructing and shaping public awareness about design culture has been the focus of the study. The main theme of the thesis is focused on the analysis of Turkish social values which changed after the 1980s and on how the magazines handled the subject of design, and the qualities which they highlighted in the presentation of the products. In addition, the roles which were ascribed to design and to the designers in terms of the newly calibrated consumption values, have also been discussed. The socio-political and economic transformations of the post-1980 period constitute the contextual framework of the thesis.

This thesis investigates human product interaction with a focus on the physical experience provided by products. The differences of users&#039 / perceptions are discussed according to the differences of bodily experiences served by products. The interaction with products is taken as a holistic experience phenomenon, and in order to assess users&#039 / understandings and evaluations about the experience with products / perceived pragmatic qualities, perceived hedonic qualities and elicited emotional reactions are analyzed. The research is conducted by means of surveys in order to compare users&#039 / perceptual differences in relation to two different product groups: automobiles and the iPhone, which differ in content of interaction, namely one serves a more physical (bodily) experience while the other a more virtual one. In order to find out the perceptual differences, verbal descriptions of perceived qualities and emotional states are used as measurement tools. A list consisting of bipolar word pairs in relation with pragmatic qualities, hedonic qualities and emotional reactions has been composed, and perceptual differences are investigated through the bipolar word pairs&#039 / relevancy levels according to the product. In addition, in order to show that meaning associations related to the same verbal description are context dependent, the meanings that are associated with the same word pairs for both products are investigated. Apparent differences between the relevant word pairs of the two different product groups have been observed, in addition with pragmatic qualities&#039 / higher relevancy scores compared to hedonic qualities and emotional reactions in defining users&#039 / interactions with products.

<p>The objective of this study was to develop and validate a six Non-CODIS miniSTR genotyping system and to determine its suitability for forensic casework in South Africa. In Non-CODIS miniSTR genotyping systems, smaller PCR products are amplified and the primers are positioned as close as possible to the repeat region. For this reason, these systems can be valuable in a variety of scenarios including complex paternity cases, missing persons work, and mass fatality disasters.</p>

À tout âge, l’exercice physique peut être bénéfique au fonctionnement cognitif. Étant quotidiennement confrontés à des situations d’apprentissage, l’enfant et l’adolescent constituent une population particulièrement susceptible de profiter de ces bienfaits. Cependant, il importe de préciser et d’étudier les facteurs qui influencent la relation entre l’exercice physique et la cognition. L’objectif général de cette thèse était d’examiner, à l’aide de mesures électrophysiologiques, les effets aigus et chroniques de l’exercice physique sur les mécanismes neurophysiologiques du fonctionnement cognitif de l’enfant. Une première étude a apprécié la durée des effets aigus de l’exercice physique. Les résultats de ces travaux suggèrent qu’une séance ponctuelle d’exercice physique augmente la vigilance pendant au moins 30 min. Toujours dans un contexte d’effets aigus de l’exercice, l’impact de la demande cognitive de la tâche et de l’âge ont été examinés dans une seconde étude. Les résultats ne révèlent aucune interaction avec l’âge, cependant ils indiquent une spécificité pour les processus plus complexes du traitement de l’information. Enfin, une troisième étude a évalué l’effet de l’exercice physique chronique dans le cadre d’un programme d’activités physiques de 12 semaines. Aucun changement n’a été observé quant à l’aptitude cardiovasculaire ou la performance cognitive suite au programme. Une condition physique initialement élevée des participants pourrait expliquer ce résultat. En résumé, peu importe la condition physique de l’enfant, un exercice physique aigu d’intensité moyenne est bénéfique à la vigilance et à certains aspects du traitement cognitif de l’information. Les effets observés semblent suffisamment durables pour avoir un impact positif sur l’apprentissage en classe après une récréation ou un cours d’éducation physique. / Exercise can be beneficial for cognitive functioning throughout lifespan. Children and adolescents may particularly benefit from the effects of exercise on cognition as they continually face learning situations. However, it is important to identify and to study the factors that influence the relationship between exercise and cognition. The general objective of this thesis was to examine, with electrophysiological measures, the acute and chronic effects of exercise on electrophysiological mechanisms of cognitive functioning in children. A first study appreciated the duration of the acute effect of a single session of exercise. The results suggested that a single session of exercise increases vigilance for at least 30 min. Still in a context of acute exercise, the impact of the cognitive demand of the task and age were examined in a second study. Although the results did not reveal any significant interaction with age, they indicated specific benefits for the more complex cognitive processes compare to more automatic processes. Finally, a third study evaluated the effect of a 12-week program of physical activity. Following the 12-week program, no change was observed neither for the cardiovascular function nor the cognitive performance. The fact that participants already demonstrated a high level of fitness at baseline may explain this result. In conclusion, regardless of a child’s fitness level, it appears that an exercise of moderate intensity improves vigilance and some aspects of information processing. The observed effects appear to last long enough to have a positive impact on classroom learning after a recess or a physical education class.

The objective of this study was to develop and validate a six Non-CODIS miniSTR genotyping system and to determine its suitability for forensic casework in South Africa.In Non-CODIS miniSTR genotyping systems, smaller PCR products are amplified and the primers are positioned as close as possible to the repeat region. For this reason, these systems can be valuable in a variety of scenarios including complex paternity cases,missing persons work, and mass fatality disasters. After the successful implementation of the genotyping system in the laboratory, allele size range was determined for each of the loci and allelic ladders were constructed. The entire repeat regions of the six loci under investigation were successfully sequenced.Consequently, allele repeat number, structure and observed size were determined for each locus.An internal validation study of the six Non-CODIS miniSTR genotyping system was conducted following the SWGDAM guidelines. A comprehensive population study,covering five population groups from South Africa was also carried out.The genotyping system produced consistent, accurate and precise genetic profiles for low concentrations of template DNA. When analyzing mixed DNA samples, successful differentiation of minor and major DNA components was identifiable. Amplification products were observed in non-human DNA studies but in all instances complete genotype profiles were not obtained. Allele frequencies and forensic parameters were determined for the system in five South African population groups (i.e. Afrikaner, Asian-Indian, Mixed Ancestry, Xhosa and Cape Muslim). No deviation from Hardy-Weinberg equilibrium was observed in any of the populations. Furthermore, all populations displayed a high power of discrimination and a high power of exclusion.The six Non-CODIS miniSTR genotyping system has shown a good potential to aid in the analysis of degraded DNA samples. This system can be further improved by including additional loci. Even in its current form, it can certainly provide additional discrimination in complex paternity and/or missing person cases. / >Magister Scientiae - MSc

The cross sections for neutral current (NC) deep inelastic scattering (DIS) in e+p collisions with a longitudinally polarised positron beam are measured at high momentum transfer squared (Q2 > 185 GeV2) at the ZEUS detector at HERA. The HERA accelerator provides e+-p collisions at a centre-of-mass energy of 318 GeV, which allows the weak contribution to the NC process to be studied at high Q2. The measurements are based on a data sample with an integrated luminosity of 135.5 pb-1 collected with the ZEUS detector in 2006 and 2007. The single differential NC cross sections dsigma/dQ2, dsigma/dx and dsigma/dy and the reduced cross section are measured. The structure function xF3 is determined by combining the e+p NC reduced cross sections with the previously measured e-p measurements. The interference structure function xF 3^gamma,Z is extracted at Q2 = 1500 GeV2. The cross-section asymmetry between the positive and negative polarisation of the positron beam is measured and the parity violation effects of the electroweak interaction are observed. The predictions of the Standard Model of particle physics agree well with the measurements.

Computer aided process planning (CAPP) is generally acknowledged as a significant activity to achieve Computer Integrated Manufacturing (CIM). In coping with the dynamic changes in the modern manufacturing environment, the awareness of developing integrated and intelligent CAPP systems has been raised in an attempt to generate more successful implementation of intelligent manufacturing systems. The main objective of this research work has been to develop an integrated intelligent process planning system that helps designers and process planners to improve their design and planning in the early stages of the product life cycle. In order to achieve this goal, the following specific objectives have been accomplished: (1) Developed a STEP-based feature modeler for building mechanical parts using high-level 3D solid features as the basic design entities. The modeler is capable of generating high-level product data in XML format according to ISO 10303-AP224 standard. This file can be used to integrate into CAPP/CAM systems without using a complex feature recognition process. (2) Developed a STEP-based intelligent process planning system for prismatic parts. The system maps STEP AP224 XML data file and produces the corresponding machining operations to generate a digital process plan in XML format according to ISO 14649 (STEP-NC) standard. A Hybrid approach of most recent techniques of artificial intelligence (neural networks, fuzzy logic and rule-based) is used as the inference engine of the developed system. Three neural network models are implemented to select machining operations, cutting tools, and machine tools. Several fuzzy logic models are utilized to select machining parameters for different machining operations, work material, and tool material combinations. The rule-based functions are utilized to perform operation sequence and setup planning. An object-oriented approach has been used in the definition and implementation of the developed system. This approach offers advantages of incremental system development and reusability. The developed system is integrated with AutoCAD using Activex automation interface. Several examples have been presented to demonstrate and verify the applicability of the developed system. Finally, this research will contribute significantly to the applicability of advanced artificial intelligent techniques in CAPP systems. The implementation of STEP technology in this research will support the integration of CAPP system with other systems in CIM environment. The developed system is intended to be an effective concurrent engineering tool that bridges the gap between design and manufacturing.
