This project explores the reliability of building a biological profile for an unknown individual based on three-dimensional (3D) images of the individual's skeleton. 3D imaging technology has been widely researched for medical and engineering applications, and it is increasingly being used as a tool for anthropological inquiry. While the question of whether a biological profile can be derived from 3D images of a skeleton with the same accuracy as achieved when using dry bones has been explored, bigger sample sizes, a standardized scanning protocol and more interobserver error data are needed before 3D methods can become widely and confidently used in forensic anthropology. 3D images of Computed Tomography (CT) scans were obtained from 130 innominate bones from Boston University's skeletal collection (School of Medicine). For each bone, both 3D images and original bones were assessed using the Phenice and Suchey-Brooks methods. Statistical analysis was used to determine the agreement between 3D image assessment versus traditional assessment. A pool of six individuals with varying experience in the field of forensic anthropology scored a subsample (n = 20) to explore interobserver error. While a high agreement was found for age and sex estimation for specimens scored by the author, the interobserver study shows that observers found it difficult to apply standard methods to 3D images. Higher levels of experience did not result in higher agreement between observers, as would be expected. Thus, a need for training in 3D visualization before applying anthropological methods to 3D bones is suggested. Future research should explore interobserver error using a larger sample size in order to test the hypothesis that training in 3D visualization will result in a higher agreement between scores. The need for the development of a standard scanning protocol focusing on the optimization of 3D image resolution is highlighted. Applications for this research include the possibility of digitizing skeletal collections in order to expand their use and for deriving skeletal collections from living populations and creating population-specific standards. Further research for the development of a standard scanning and processing protocol is needed before 3D methods in forensic anthropology are considered as reliable tools for generating biological profiles.

Diagnosis Technologies based on images and their use to plan advanced therapies have assumed a protagonist position in t he field of biotechnology. In this scenario the 3D Laboratory of Nucleus of Strategic Technologies in Health (NUTES) - LABTEC 3D / NUTES – afiliated to Universidade Estadual da Paraíba (UEPB) has been pioneering in the production of biomodels for surgical planning of polytraumas. Biomodels are high precision 3D reproductions of specific part of the human anatomy built up from an image exame of the patient. The current manufacturing process requires improvments on how its production stages are managed, so as to unify the information regarding both the biomodel manufactured and the toolset used throughout the different steps executed. In addition, properly registrating the proccess execution might be of a valuable use in subsequent research and treatment, either for LABTEC 3D / NUTES or in joint efforts with local and international partners. This work presents a semi automed solution to enhance the workflow currently executed to manufacture biomodels at LABTEC3D / NUTES, which makes it possible to electronicall y register and control the steps of production. The solution makes use of an interoperability technological framework that scales to a 3D Labs federation, with the purpose to register and miner relevant information on treatments and research in the medical and dental areas. / Nos últimos anos as Tecnologias de Informação vêm se tornando mais determinantes na evolução de diagnóstico, tratamentos e gestão em saúde. Tecnologias de diagnóstico por imagem e seu uso no planejamento de terapêuticas avançadas têm assumido uma posição d e destaque no ramo da biotecnologia. É neste cenário que o Laboratório de Tecnologias 3D do Núcleo de Tecnologias Estratégicas em Saúde (NUTES) – LABTEC 3D/NUTES – da Universidade Estadual da Paraíba (UEPB) vem fabricando com pioneirismo biomodelos para planejamento cirúrgico de politraumatismo. Biomodelos são reproduções em 3D, com alta precisão, de parte específica da anatomia humana a partir de uma imagem do paciente. O atual processo de fabricação é a origem da necessidade de se gerir a etapas de produç ão, unificar as informações referentes ao biomodelos e ferramentas utilizadas nos diferentes passos executados, garantindo ainda o devido registro para pesquisas e tratamentos posteriores, internos ou em conjuntos com parceiros locais e internacionais. Este trabalho apresenta uma solução de automação da gestão e workflow na fabricação de biomodelos no LABTEC 3D/NUTES, que possibilita registrar e controlar por meio eletrônico as etapas de produção, além de criar uma estrutura que possibilite a interoperabilidade entre as informações clinicas referente ao biomodelo. Estrutura no qual visa posteriormente a extração de informações relevantes para tratamentos e pesquisas nas áreas médica e odontológica.

In this context, the main objective of this project is to determine if 3D printed concreteformworks are able to not fall apart and later withstand the stresses produced byC40/50 and selfcompactingconcrete (SCC) castings. The purpose is to check thesuitability of this method applied to the construction of bridge pillars and its capabilityof covering and protecting the reinforcement placed in the casting. The methodconsists of the design and construction of the formworks, the casting of the SCCcolumns and the performance of compression and bond tests to samples extracted fromthe sections presented to check the resistance and the bond between the formwork andthe interior concrete casting.The results obtained showed that the formworks did not fall apart and could withstandthe stresses caused by the casting. In addition, the casting presented a better bond atthe bottom of the sections in both cases. Although C40/50 presented a higher bondand compression strength than SCC, it showed a bond problem at the top part thathighlighted the importance of vibrating the concrete mix properly.After analysing all the results a clear conclusion is not reached, so further research inthis field needs to be done in order to build bridge pillars with this technology.

The purpose of this experimental study was to investigate the effect of stereoscopic three-dimensional (S3D) images on productive and receptive recall of foreign language vocabulary. S3D images are highly-realistic and differ from non-stereoscopic three-dimensional (NS3D) images in that they provide the impression of the added third dimension of depth. This within-subject study exposed the participants (N = 82) in a controlled setting to a series of carefully designed and randomly distributed NS3D and S3D images. The subjects were then given immediate productive and receptive tests of foreign language vocabulary items that were represented by NS3D and S3D images. Quantitative data consisted of the scores from the vocabulary tests. Qualitative data, gathered through background questionnaires and follow-up surveys, included a mixture of open-ended and Likert questions. The statistical analyses of the data using a series of paired t-tests showed NS3D and S3D images to be equally effective for vocabulary recall. In addition, significantly more subjects found S3D images to be engaging and/or more useful, while subjects also indicated that they perceived the main benefits of learning with S3D images to come from enhanced focus, realism, engagement, and association. At the same time, some learners reported being distracted and experiencing discomfort while viewing S3D images. Post hoc tests revealed that lower performance on S3D images was driven only by those subgroups that exhibited discomfort and / or lack of experience with S3D technology.

The purpose of this study is to determine the viability of this technology as a realistic archaeological field tool and discuss what advantages, limitations, and implications this technology has for the purposes of archaeological field survey in Sweden. To determine this, five targets in Stockholm County already professionally surveyed and documented, have been scanned with LiDAR as well as two also with photogrammetry via smartphone apps on an iPhone 12 Pro Max to compare the scanning process and the respective results for each target. After analysing targets in Angarn, Fresta, Sollentuna, Österhaninge, and Kärrtorp parishes, a post-phenomenological perspective was applied to each model to discuss their potential as technologically mediated human experiences. An additional sixth target was scanned to compare against other 3D techniques. This study has determined that the photogrammetry tools in the apps provided the best conditions and results for use in archaeological field survey documentation while the LiDAR tools have room for improvement as a professional tool.

The rapid technological advancement and the increased awareness about the environment have introduced new digital tools to facilitate the design process in the fashion industry in which 3D technology was incorporated. Very few research has addressed the experiences of fashion designers when using 3D tools in their design process. Most of the previous research in this field focused on the technical aspects of using 3D design tools. Hence, this paper aims to investigate the experiences of fashion designers working with 3D design tools by answering the research question "What are the pros and cons of implementing 3D digital technology in the fashion industry on the design process of designers?”. Semi-structured interviews were undertaken through Zoom with eight fashion designers located in different countries, and the data obtained were analyzed through thematic analysis. Most of the 3D designers participating in this study use CLO3D as a main program to design digital garments as it is efficient and holds a high degree of control and advanced settings. The results revealed seven themes, namely: flexibility and realism, improved communication, sustainability, gap between the digital and physical prototype, necessity of proper knowledge and training, limited creativity, and customization, and lastly, lack of social acceptance. The first three are considered pros whereas the latter four are cons. The discussion of results differentiated between two stages which are sketching and prototyping where most advantages are found in the sketching phase. Therefore, further technological advancements are needed to improve the properties of virtual garments in addition to a change of stakeholder mentality in order to embrace and accept digital technology. Hence, this study will benefit later research in the field to improve 3D tools and close the gap between physical and virtual prototypes.

科技總會來到另一種新的境界，物聯網、大數據、雲端、人工智慧，已經逐漸走進並改變人類生活。但若當這些元素融入到生產的上、中、下游時會是什麼光景？ 近年來，在要求品質和個性化的結果，大量生產、規格外觀齊一的產品已不再能吸引消費者，消費者要求有差異化的產品，要能針對客戶個別的需求，提供有特色的產品和服務成為一種趨勢。另一方面，市場變化太大，不論產品週期、上市時間、新的行銷通路，都不斷地在演變，為了提供高品質的產品和服務，對企業紛紛要求要必須具備快速回應的能力(fast responsiveness)，因此大量客製化(mass customerization)成為企業營運不能迴避的重要課題。 為了實現大量客製化，企業已不能再沿用過去傳統的生產模式，應從建構新企業模型的宏觀角度，思考企業所欠缺的以及必須因應改變的創新。在工業時代給員工的報酬是基於對公司成果（business outcomes）的貢獻；在資訊時代給員工的報酬是基於對客戶成果（customer outcomes）的貢獻。而工業4.0時代更標著明確目標：生產全面聯網，智能製造。 婚紗禮服有別於一般成衣服裝，早已是大量客製化程度極高的產業，但在生產成本與時間效益上，卻是進展緩慢。因此如何運用新工業時代與科技的創新，建構出新客製化企業模型，才能讓顧客更便捷並以合理價格，來選擇依自己需求訂製夢想的婚紗。 本研究擬由JAS婚紗禮服客製化歷程的個案探討中，歸納出運用3D技術的發展與運用確實可為大量客製化過程增加效益，後續若能發展物聯網功能的系統裝置，相信更能全面實現大量客製化策略，並為創造新利基市場婚紗禮服業參考。 / Technology is taking us into a new realm. IOT, big data, cloud computing, artificial intelligence have gradually changed our lives. But what if we put these elements into the production process, what changes would it bring? In recent years, quality requirements and personalization result in the products which are mass production and standardization are no longer to attract consumers. Consumers require a differentiation product which can meet the individual customer's needs, providing them unique products and services. On the other hand, the market has changed so much, regardless of the product cycle, time to market, new marketing channels are constantly evolving in order to provide high quality products and services. The enterprise must have asked to have the ability to respond quickly (fast responsiveness), so a lot of customization (mass customization) business operations become important issues. In order to achieve a lot of customization, companies can’t longer follow the traditional mode of production in the past. We should construct a macro point of a new business model, thinking enterprises lacking and the need to respond to change and innovation. In the industrial era, the staff remuneration is based on the contribution of the company's achievements (business outcomes); and in the information era, the staff remuneration is based on contribution to the outcome of the customer (customer outcomes). The industrial 4.0 era mark more clear goal: the production of a comprehensive networking, intelligent manufacturing. Unlike ordinary wedding dress readymade garments, it has long been a large number of very high degree of customization of the industry, but in the production cost and time-effective, it is slow. Therefore, how to use the new industrial age of innovation and technology, the construction of a new customized business model in order to allow customers to more easily and at a reasonable price, to choose according to their needs customized dream wedding. As a case with JAS which provide customized wedding dress, we want to concluded the use of 3D technology and large number customization will increase process efficiency. Besides that with Internet of things, we believe that we can reach out more mass customization strategies and create new niches for the wedding dress industry.

Les travaux de cette thèse s’inscrivent dans un projet de grande envergure, le projet 3D-IDEAS, financé par l’ANR. Le but de ce projet est d’établir la chaîne complète de l’intégration de circuits en technologie 3D. Les densités de puissance dans ces circuits sont telles que les problèmes liés à la température – électromigration, désappariement des courants et tensions de polarisation, etc. – sont susceptibles de remettre en cause la conception du circuit. Le coût élevé de la fabrication de ces circuits oblige le concepteur à valider le comportement électrothermique des circuits préalablement à l’envoi en fabrication. Pour répondre à ce besoin, un simulateur électrothermique précis et fiable doit être à disposition. En outre, en raison de la complexité extrême de ces circuits, il est judicieux que ce simulateur soit compatible avec l’approche de modélisation haut niveau. L’objectif de cette thèse est de développer un tel simulateur. La solution proposée intègre ce simulateur dans un environnement de développement CAO pour circuit intégré standard, Cadence®. La contrainte sur la précision des résultats nous a amené à développer une nouvelle méthodologie spécifique à la modélisation électrothermique haut-niveau. Ce manuscrit comporte deux grandes parties. Dans la première, la démarche adoptée pour concevoir le simulateur est détaillée. Ensuite, dans la seconde partie, le fonctionnement du simulateur ainsi que la méthode de modélisation haut-niveau mise en place sont présentées, puis validées. / The work of this thesis is part of a larger project, the project 3D-IDEAS, funded by the ANR. The purpose of this project is to establish the complete chain of integrated circuits built upon 3D technology. Power densities in these circuits are exacerbated, thus problems related to temperature, such as electromigration, mismatch of bias currents and voltages, etc., arise and might have critical effects on the circuit behavior. The high cost of these circuits requires the designer to validate the electro-thermal behavior of circuits prior to manufacturing. To meet this need, an accurate and reliable electro-thermal simulator should be available. Moreover, due to the extreme complexity of these circuits, it is wise for such a simulator to be compliant with high level modeling approach. The objective of this thesis is to develop such a simulator. The proposed solution integrates the simulator in the broadly used CAD environment for integrated circuits Cadence®. The need of accurate results led us to develop a new methodology specific to high level electro-thermal modeling. This manuscript is split in two major parts. In the first one, the approach to implement the simulator is detailed. Then, in the second part, the operation principle of the simulator and the modeling method implementation are detailed and validated.
