Résumé :
In this thesis, autopilots are developed for missiles with moderate dynamics and stationary targets. The aim is to use the designs in real applications. Since the real missile model is nonlinear, a linearization process is required to get use of systematic linear controller design techniques. In the scope of this thesis, the linear quadratic full state feedback approach is applied for developing missile autopilots. However, the limitations of measurement systems on the missiles restrict the availability of all the states required for feedback. Because of this fact, the linear quadratic design will be approximated by the use of projective control theory. This method enables the designer to use preferably static feedback or if necessary a controller plus a low order compensator combination to approximate the full state feedback reference. Autopilots are checked for the validity of linearization, robust stability against aerodynamic, mechanical and measurement uncertainties.

In this thesis, we study the Projective Re-Normalization method (PRM) for semidefinite programming feasibility problems. To compute a good normalizer for PRM, we propose and study the advantages and disadvantages of a Hit & Run random walk with Dikin ball dilation. We perform this procedure on an ill-conditioned two dimensional simplex to show the Dikin ball Hit & Run random walk mixes much faster than standard Hit & Run random walk. In the last part of this thesis, we conduct computational testing of the PRM on a set of problems from the SDPLIB [3] library derived from control theory and several univariate polynomial problems sum of squares (SOS) problems. Our results reveal that our PRM implementation is effective for problems of smaller dimensions but tends to be ineffective (or even detrimental) for problems of larger dimensions.

Résumé :
Educational games have become an established paradigm of instructional practice; however, there is still much to be learned about how to design games to be the most beneficial for learners. An important consideration when designing an educational game is whether there is good alignment between its content goals and the instructional behaviors it makes in order to reinforce those goals. Existing methods for measuring alignment are labor intensive and use complex auditing procedures, making it difficult to define and evaluate this alignment in order to guide the educational game design process. This thesis explores a way to operationalize this concept of alignment and demonstrates an analysis technique that can help educational game designers to both measure the alignment of current educational game designs and predict the alignment of prototypes of future iterations. In my work, I explore the use of Replay Analysis, a novel technique that uses in-game replays of player sessions as a data source to support analysis. This method can be used to capture gameplay experience for the evaluation of alignment, as well as other forms of analysis. The majority of this work has been performed in the context of RumbleBlocks, an educational game that teaches basic structural stability and balance concepts to young children. Using Replay Analysis, I leveraged replay data during a formative evaluation of RumbleBlocks to highlight some misalignments the game likely possesses in how it teaches some concepts of stability to players. These results led to suggestions for several design iterations. Through exploring these design iterations, I further demonstrate an extension of Replay Analysis called Projective Replay Analysis, which uses recorded student replay data in prototypes of new versions of a game to predict whether the new version would be an improvement. I implemented two forms of Projective Replay: Literal Projective Replay, which uses a naïve player model that replays past player actions through a new game version exactly as they were originally recorded; and Flexible Projective Replay, which augments the process with an AI player model that uses prior player actions as training data to learn to play through a new game. To assess the validity of this method of game evaluation, I performed a new replication study of the original formative evaluation to validate whether the conclusions reached through virtual methods would agree with those reached in a normal playtesting paradigm. Ultimately, my findings were that Literal Projective Replay was able to predict a new and unanticipated misalignment with the game, but Flexible Projective Replay, as currently implemented, has limitations in its ability to explore new game spaces. This work makes contributions to the fields of human-computer interaction by exploring the benefits and limitations of different replay paradigms for the evaluation of interactive systems; learning sciences by establishing a novel operationalization of alignment for instructional moves; and educational game design by providing a model for using Projective Replay Analysis to guide the iterative development of an educational game.

Nature based tourism is a growing trend across the world today. Ecotourism is a specific nature based tourism type, defined by the International Ecotourism Society (TIES) as “Responsible travel to natural areas that conserves the environment and improves the well-being of local people.” The ‘ecolodge,’ is a term that refers to the site and structure where ecotourists stay and where ecotourism activities occur. The intention of an ecolodge is to find a balance between three factors: conservation, local communities, and interpretation for travelers and workers. Every ecolodge is unique in form and function to uphold sustainability best practices and to meet specific environmental and climatic needs of a region. As more and more tourists choose to travel to environmentally sensitive areas of the world, ecolodge use must increase in order to preserve environmental and cultural assets (Honey, 2008). In other countries, like Costa Rica and Kenya, many ecolodges have successfully balanced these three components creating an overall trend towards ecolodges and ecotourism operations, shifting away from traditional accommodation types. However, as the U.S. tourism market continues to grow, there is yet to be a notable ecolodge presence. Some ecotourism experts would argue that true ecotourism--equally finding balance between conservation, guest interpretation, and community support--will never be possible to create in the U.S. Many believe it is the ‘supporting local communities’ aspect of ecotourism which cannot be met. The treatment of indigenous people, as well as the structure of the nation’s economy in the U.S. is different compared to developing countries where ecolodge design has found success. Interestingly, certified sustainable site development is becoming prevalent in the U.S. Frameworks such as LEED and SITES are used to improve the rigor of sustainability design. Design guidelines for ecolodges share similar goals with LEED and SITES. But ecolodge design is not prevalent in the U.S. This may be due to the lack of an international ecolodge certification system. If the ecotourism industry can progress from ecolodge guidelines (which are largely unknown) to an international ecolodge certification, truly authentic ecolodges will become the standard (Mehta, 2007). To explore how ecolodges can be used in a U.S. National Park, this project focuses on the Flamingo District in the Everglades National Park, Florida. A projective design methodology is used. The data collection methods include precedent studies, interviews, on-site observation, and site analysis. Flamingo, located in the southernmost point of the Everglades was destroyed by hurricane Katrina in 2005. The National Park Service is seeking a business concessioner to 1) oversee the construction of new lodging area, and 2) operate all business activities—recreation rentals, marina operations, general store, and dining—in the district. The goal of this research project is to create an ecolodge design that can serve Flamingo’s needs and serve as a model for future ecolodge design in U.S. National Parks.

This reflection takes place in the contest of the FAU-Mackenzie and takes as substrate the author s experience in Design course as a supervisor in the (TCC) Final Graduation Project in the area of jewelry. Part of reflection on how the graduate works are analysed, seeking to explain and develop its conceptual and practical tools. Takes as its theoretical basis, the study of history, arts, crafts and design, in order to contribute to the definition of a field, specifically regarding the building of knowledge in the area of design practice and jewelry design research. The context is presented in a brief review of the literature on inadequacies in the use of terms design, craft and art, with focus in the area of jewelry design, which mobilize the categories or confuse and complicate the discourses based on the conventional definitions and distinct studies of visual and material practice. At first we assume that academic research in areas of design practice, similarly to what happens, for example, with the arts, it is usually described, explained, discussed and read through the vocabulary stemming from the theory of traditional science, focusing on aspects as method and content. However, we are often not satisfied with a terminology that does not capture the events we experience as being essential and fascinating in design. In the proposed study, some aspects of this dissatisfaction are discussed and as well as a reflection on the issue is performed of process to the design procedures of jewelry in the academic realm. The research infers, from the proceedings in a selection of TCC, which can lead to the solution of problems via design tools, not be so closely linked to the academic literature. As a resource for this research, we used concepts from articles such as Eight criteria of academic research in areas of practice projetual , from authors such as Michel Biggs and Daniela Büchler, as well as works by Ana Gabriela Godinho Lima and Steven Scrivener, in a discussion of academic research techniques regarding the design methods in the academic research based on jewelry design.
Essa reflexão se dá no contexto da FAU-Mackenzie e toma como substrato a experiência da autora no curso de Design, como orientadora de Trabalhos de Conclusão de Curso (TCC) na área de joalheria. Parte da reflexão sobre o modo como os trabalhos de graduação são elaborados, que buscam explicar e desenvolver as ferramentas práticas e conceituais. Toma como fundamentação teórica, o estudo da história, artes, artesanato e design, com a finalidade de contribuir para a delimitação de um campo disciplinar: formação do conhecimento na área da prática projetual e pesquisa em design de joia. É apresentada uma rápida revisão da literatura sobre inadequações quanto ao uso dos termos design, artesanato e arte, e as especificidades que se apresentam na área de joalheria, que mobilizam ou confundem as categorias e complicam os discursos baseados em definições convencionais e distintas a partir de estudos de casos de prática visual e material. A princípio assumimos que a pesquisa acadêmica na área de design, similarmente ao que ocorre, por exemplo, com as artes, é usualmente descrita, explicada, discutida e lida através do vocabulário provindo da teoria da ciência tradicional, ou seja, com foco no método e no conteúdo. Entretanto, frequentemente não nos satisfazemos com uma terminologia que não captura o que experimentamos como sendo eventos essenciais e fascinantes das artes, e acrescentamos: do design. No estudo proposto, são abordados alguns aspectos dessa insatisfação, e na reflexão sobre a questão de processo ao método projetual de joalheria em âmbito acadêmico. A pesquisa faz recurso à análise de processos de projeto com uma seleção de Trabalhos de Conclusão de Curso (TCC), em que aspectos práticos, o saber fazer do design de joias é convocado como parte principal do trabalho. Ou seja, servem como base útil para a reflexão sobre aspectos da pesquisa acadêmica em design de joias e a projeção sobre como esse tipo de pesquisa pode avançar para os níveis de mestrado e doutorado. Como recurso necessariamente complementar para essa investigação, empregou-se referencial teórico constituído por trabalhos de autores mais especificamente voltados à pesquisa acadêmica em áreas de prática projetual em âmbito de pós-graduação stricto sensu, tais como: Michel Biggs, Daniela Büchler, Ana Gabriela Godinho Lima, Steven Scrivener e é uma discussão de pressupostas técnicas de pesquisa acadêmica pensada nesta tese, para a questão do processo ao método projetual de joalheria em âmbito acadêmico.

Résumé :
Projecting Urban Natures is a compilation thesis in critical studies in architecture. It comprises three journal articles and four design proposals in which I have taken an active part. The point of departure for this thesis is the renewed emphasis on social-ecological interaction and resilience that is currently taking place within ecological systems science, and the opportunities that these paradigmatic insights in turn have opened up within urbanism and design. The thesis argues that although they are promising, these emerging integrative frameworks are seldom brought into mainstream planning and urban design practice. Instead, the structuring of “nature” and “city” into a dualistic balance relationship still permeates not only the general planning discourse, but also makes its way into planning documents, notably influencing distinctions between professions. In response, this thesis sets out to rethink and explore more integrated approaches to human/nature relationships, through the utilization of design-based and transdisciplinary research methods. While this core aim of the thesis remains the same throughout the work, the task is approached from different perspectives: through different constellations of collaborative work as well as through parallel case-based explorations that emphasize the relational, anti-essentialist and situated articulation of values of urban natures and how these forces come into play. The work has been propelled through workshop-based, site-specific, and experimental design processes with professionals and researchers from the fields of e.g. systems ecology, natural resource management, political ecology, urban design, architecture, and landscape design, as well as planners, developers, local interest groups, and NGOs. Specifically, projects performed within this thesis include: Nature as an Infrastructural Potential – An Urban Strategy for Järvafältet; Kymlinge UrbanNatur together with NOD, Wingårdhs, MUST and Storylab; Årsta Urban Natures with James Corner Field Operations and Buro Happold; and Albano Resilient Campus — a collaboration between Stockholm Resilience Centre, KTH and KIT.

Texte intégral
Résumé :
A (finite) projective plane of order m, m an integer greater than 1, is a 2- (m^2 + m + 1, m + 1, 1) design. A unital (or a unitary block design) U of order n, n an integer greater than 2, is a 2-(n^3 + 1, n + 1, 1) design. An embedded unital is one that is a subdesign of a projective plane. If a unital of order n is embedded in a projective planeπ, then the order of π is at least n^2. A unital of order n embedded in a projective planeπ of order n^2 is called a polar unital if it consists of the absolute points and non-absolute lines of a unitary polarity of π. In particular, if π is the classical (Desarguesian) plane PG(2, q^2) coordinatized by the finite field Fq^2, then the polar unital is called a classical unital. The main problem in the study of unitals is their characterization and classification. The classical unital does not contain a configuration of four lines meeting in six points (an O'Nan configuration) [O'Nan, 1972]. It is conjectured that this property characterizes the classical unital [Piper, 1979]. The classical unital is characterized by three conditions (I), (II) and (III): (I) is the absence of O'Nan configurations; (II) and (III) are further configurational requirements [Wilbrink, 1983]. The result depends on the classification of finite doubly transitive groups. Furthermore, when the order of a unital is even, (III) is a necessary condition of (I) and (II) [Wilbrink, 1983]. As for group theoretic characterizations, the only unitals that admit doubly transitive automorphism groups are the classical unitals and the Ree unitals [Kantor, 1985]. The classical unital is also characterized by the existence of sufficiently many translations [Grundhöfer, Stroppel, Van Maldeghem, 2013]. In this thesis, a necessary and sufficient condition is given for embedding a unital into a projective plane as a polar unital. A strengthened version of the condition is introduced and is shown to be necessary for a classical unital. Using the strengthened condition and results of [Wilbrink,1983] and [Grundhöfer, Stroppel and Van Maldeghem, 2013], a new intrinsic characterization of the classical unital is given without assuming the absence of O'Nan configurations. Finally, a unital of even order satisfying the first two intrinsic characterization conditions of Wilbrink is shown to be classical without invoking deep results from group theory.

Collecting information becomes a crucial advantage for the military in combat situations. One area lacking in this domain is to rapidly obtain information which is not far from the frontline. For instance, today's military commander would have to deal with a complex hierarchy to obtain information on the enemy's location which is only a few miles away. Hence, the main objective of this project was to provide the Navy with a quick and cheap way to perform visual, short range reconnaissance missions. The concept is to launch a projectile containing an unmanned aircraft to a desired location for surveillance. This Wide Area Surveillance Projectile or WASP was developed within the context of the MIT/Draper Technology Development Partnership Project, which aimed at the development of a first-of-a-kind system within a time-frame of two years and the development of an entrepreneurial spirit in the participating engineering students at MIT. The advantage of this concept is that a surveillance mission can be done quickly, at low cost, and without any landing strip. This report describes the trade studies performed in selecting the best aerodynamic configuration in terms of performance and stability. The deployment system is an integral part of the aerodynamic performance. In the static stability analysis, the aerodynamic configuration was modeled and analyzed using existing software, to provide sufficient control for a flexible mission. In addition, the flight trajectories and deployment sequences were designed and analyzed for an optimum deployment process.

Résumé :
There is an underpinning requirement for artillery systems to achieve longer range, better precision, and an adequate lethal effect. The main objective of this research is to investigate various methods of range increase and propose optimal solution for range extension of existing artillery systems. The proposed solution is novel, modular projectile design. Several methodologies for projectile range increment (such as improved aerodynamics and ballistic profile) were combined to achieve the "goal'", but mainly work was concentrated on projectile's "assisted" propulsion with Base Bleed (BB) and Solid Rocket Motor (SRM). The gun's interior ballistics, i.e. ordnance parameters (propelling charge, volume of combustion chamber, length of the barrel and muzzle velocity) remains unchanged. The novel concept of modular design of an artillery projectile includes separate modules for propulsion, drag reduction, and payload. Various payload module configurations should allow diverse lethal effects, and four different propulsion configurations allow engagement of various targets. Among all "possible' projectile configurations, the focus was on arrangement that will fly longest from given ordnance, with fragmentation effect on target. To achieve projectile's "aims," it required development of new chemical composition for BB and SRM propellant. In addition, new type of BB propellant grain geometry was developed, for efficient base drag reduction (by injecting sufficient amount of gaseous products in the downstream wake zone of the projectile base), and new SRM module was designed for projectile range enhancement. Both propellant compositions and grain shapes were optimised to produce required "thrust" and to withstand severe gun launching conditions - high acceleration and pressure in gun barrel. The research work also includes investigation and optimisation of complex flight mechanics of a gun launched - solid rocket motor propelled - base bleed projectile, as well aerodynamic shape optimisation, and overall modular projectile design optimisation in order to improve payload efficiency. The research work covers theoretical calculations, numerical simulations and their validation through experiments, with results confirming the feasibility of the concept.

Recently, bistable springs have been proven as a viable propulsion method for the standard 1.75" foam balls used in Nerf® projectile toys. This technology was developed at M.I.T. by William Fienup and Barry Kudrowitz, who designed a single-shot hand-popper that utilized a large bistable spring. The goal of this research was to design and develop a projectile toy capable of safely firing multiple foam balls in succession, using this novel propulsion. A structured design process was followed and this toy, the shot-popper, was brought to the alpha-prototype level. Largely this project was a success. Between the shot-popper, and the flat model that came before it, every module of the toy was shown to function as desired.

The goal of this research was to design and develop a working prototype of a new toy for Hasbro®'s Nerfe line of foam projectile toys. Several years ago, Hasbro approached the MIT CADlab about developing a new method for firing Nerfe foam balls. The hope was that a new approach would be generated from which a new platform of products could be developed. The result of the initial work was the development of Hopper Popper ActivationTM, which uses a bistable rubber spring to fire Nerf foam balls. Due to its novel nature and the simplicity of its design, Hopper Popper Activation has since been integrated into a single projectile toy named the Atom BlasterTM, which reached the market in early 2007. Following the success of this project, Hasbro requested that a multi-shot projectile toy be developed that makes use of Hopper Popper ActivationTM, so that it may extend the platform of toys which use this new firing mechanism. This thesis follows the product design process that led to the development of the Multi-Shot PopperTM, which incorporates Hopper Popper ActivationTM into a toy blaster capable of storing and rapidly firing multiple foam ball projectiles. In addition to using Hopper Popper ActivationTM, the Multi-Shot PopperTM was required to fulfill several other requirements, including specific safety and performance specifications, while still remaining a fun and enjoyable toy. The design team created a series of iterative sketch models to test different mechanisms and methods of accomplishing the stated functional requirements. At each stage of the process, the successes and shortcomings of the current model were assessed and small scale brainstorming sessions were held to generate new concepts. These new concepts were combined with the successful features of the previous models until a final alpha-prototype was created which meets the customer and user requirements.

A design project on the development of an interactive robot system for display in the MIT Museum Studio gallery. The system consists of a moving projection surface, a projector, and an external camera with motion detection. When the external camera senses motion in the hallway outside of the gallery, it takes a picture. If a face is visible in the image, the image is cropped and displayed on the projector. The external controller notifies the moving surface that it should try to orient itself within a projection field. The projection surface uses its internal camera to continuous take images through the translucent projection material and determines whether it or not it needs to move to be within the projection field. Through this series of interactions, the robot essentially "borrows" the faces of those who pass the studio, catching projected imagery of their faces on the "face" of the projection surface. With this interaction in mind, the projection surface was designed to mimic human qualities, with an abstract head, neck, and organic body. This thesis encompasses the design and documentation of the physical robot, as well as the design and programming of one series of interactions that could be performed by this robot. This thesis represents a snapshot of the current progress of this project. Besides performing the interaction sequence described above, a secondary goal of this project is to a create an easily programmable and well documented project that future students of the MIT Museum Studio can modify for new displays and projects.

Ever-increasing demands for accuracy and range in modern warfare have expedited the optimization of projectile design. The crux of projectile design lies in the understanding of its aerodynamic properties early in the design phase. This research first investigated the aerodynamic properties of a standard M549, 155mm projectile. The transonic speed region was the focus of the research as significant aerodynamic variation occurs within this particular region. Aerodynamic data from wind tunnel and range testing was benchmarked against modern aerodynamic prediction programs like ANSYS CFX and Aero-Prediction 09 (AP09). Next, a comparison was made between two types of angle of attack generation methods in ANSYS CFX. The research then focused on controlled tilting of the projectile’s nose to investigate the resulting aerodynamic effects. ANSYS CFX was found to provide better agreement with the experimental data than AP09.

In this work novel high-order hybridizable discontinuous Galerkin (HDG) projection methods are further developed for ocean dynamics and geophysical fluid predictions. We investigate the effects of the HDG stabilization parameter for both the momentum equation as well as tracer diffusion. We also make a correction to our singularity treatment algorithm for nailing down a numerically consistent and unique solution to the pressure Poisson equation with homogeneous Neumann boundary conditions everywhere along the boundary. Extensive numerical results using physically realistic ocean flows are presented to verify the HDG projection methods, including the formation of internal wave beams over a shallow but abrupt seamount, the generation of internal solitary waves from stratified oscillatory flow over steep topography, and the circulation of bottom gravity currents down a slope. Additionally, we investigate the implementation of open boundary conditions for finite element methods and present results in the context of our ocean simulations. Through this work we present the hybridizable discontinuous Galerkin projection methods as a viable and competitive alternative for large-scale, realistic ocean modeling.

Résumé :
Mask Projection Microstereolithography (MPSLA) is an additive manufacturing process capable for fabricating true three-dimensional microparts and hence, holds promise as a potential micro-fabrication process for micro-machine components. With only a few MPSLA systems developed and studied so far, the research in this field is inchoate and experimental in nature. The process of curing a micropart using an MPSLA system has not been analytically modeled and no literature on process planning for MPSLA is available. In order to employ the MPSLA technology for microfabrication, it is necessary to model its part building process and formulate a process planning method to cure dimensionally accurate microparts. As a part of this thesis, an MPSLA system is designed and assembled. The process of curing a single layer using this system is analytically modeled as the Layer cure model. The Layer cure model is formulated in two steps. First, the irradiance received by the resin surface is modeled as a function of the system parameters (Irradiance model). Then, the resin used in the system is characterized to experimentally determine its working curve. The Irradiance model and the resin characterization enable us to compute the dimensions of any layer cured using our MPSLA system in terms of the process parameters. The Layer cure model has been validated by curing test layers on our system. Finally, the Layer cure model has been inverted to formulate a process planning method to cure layers of the required dimensions. Using this process planning method, it is possible to cure layers within a dimensional error of 3%.

In the past, airplanes, target drones, pods, and large missiles have been instrumented with telemetry, flight termination and beacon tracking antennas to assess performance. With the emerging use of the Global Positioning System (GPS) for tracking purposes, GPS is also included as part of the instrumentation package. This paper addresses the design of a conformal wraparound antenna system to cover the telemetry and GPS L1 frequencies for a small (2.75 inch) diameter airborne projectile. A filter is also integrated into the antenna system to isolate the transmitted telemetry signal from the received GPS signal. This integration is necessary due to the lack of space in the small diameter projectile. Performance characteristics of the prototype antenna system are also presented.

Résumé :
Conventional head-mounted projection displays (HMPDs) contain of a pair of miniature projection lenses, beamsplitters, and miniature displays mounted on the helmet, as well as a retro-reflective screen placed strategically in the environment. We have extened the HMPD technology integrating the screen into a fully mobile embodiment. Some initial efforts of demonstrating this technology has been captured followed by an investigation of the diffraction effects versus image degradation caused by integrating the retro-reflective screen within the HMPD. The key contribution of this research is the conception and development of a mobile-HMPD (M-HMPD). We have included an extensive analysis of macro- and microscopic properties that encompass the retro-reflective screen. Furthermore, an evaluation of the overall performance of the optics will be assessed in both object space for the optical designer and visual space for the possible users of this technology. This research effort will also be focused on conceiving a mobile M-HMPD aimed for dual indoor/outdoor applications. The M-HMPD shares the known advantage such as ultra-lightweight optics (i.e. 8g per eye), unperceptible distortion (i.e.less or equal to]2.5%), and lightweight headset (i.e.less than or equal to]2.5 lbs) compared with eyepiece type head-mounted displays (HMDs) of equal eye relief and field of view. In addition, the M-HMPD also presents an advantage over the preexisting HMPD in that it does not require a retro-reflective screen placed strategically in the environment. This newly developed M-HMPD has the ability to project clear images at three different locations within near- or far-field observation depths without loss of image quality. This particular M-HMPD embodiment was targeted to mixed reality, augmented reality, and wearable display applications.

Recent advances in material processing are presenting groundbreaking opportunities for biomedical engineers. Projection-micro-stereolithography, or PuSL, is an additive manufacturing technique in which complex parts are built out of UV-curable resins using ultraviolet light. The primary strength of PuSL is its capacity to translate CAD files into three-dimensional parts with unusually small feature sizes (~0.5 microns). It is an ideal candidate, therefore, for making tissue scaffolds with sophisticated microscopic architecture. Nearly all multicellular biological tissues display a hierarchy of scale. In human tissues, this means that the mechanics and function of an organ are defined by structural organization on multiple levels. Macroscopically, a branching blood supply creates a patent network for nutrient delivery and gas exchange. Microscopically, these vessels spread into capillary beds shaped in an organ-specific orientation and organization, helping to define the functional unit of a given tissue. On a nano-scale, the walls of these capillaries have a tissue-specific structure that selectively mediates the diffusion of nutrients and proteins. To craft a histologically accurate tissue, each of these length scales must be considered and mimicked in a space-filling fashion. In this project, I sought to generate a cellular, degradable tissue scaffolds that mimicked native extracellular matrix across length scales. The research described here lays the groundwork for the generation of degradable, vascularized cell scaffolds that might be used to build architecturally complex multi-cellular tissues suitable for both pharmacological modeling and regenerative medicine.

This thesis proposes the direct building of physical-spatial continuities with a generous range of sizes, from site size down to human size, producing an environment of multi-optional use. The work is partially reaction to certain modem tendencies in architecture that reduce the built landscape to closed, object-like, discrete physical elements. The disparity in the range of sizes from large to small intensifies the discontinuity in contemporary, mid-to-high density urban environments. The design exploration entails the transformation of an abandoned series of packed cylindrical grain containers to a structure habitable as a mid-rise (10-12 stories) three dimensional built landscape. References describe select problems and examples of: the circle as a geometric construct and some of its intrinsic behaviors the circle-cylinder in architecture built landscape transformations.

Texte intégral
Résumé :
This practice-based research investigates how projection mapping develops a distinctive relationship between screen, moving image, and space in projected moving-image art. Despite projection mapping’s growing popularity, little in-depth research has been conducted on this medium. This lack of research and the superficial nature of many projects have led artists and researchers to regard the medium as a mere technique that serves only to decorate three-dimensional surfaces. Rather than view projection mapping simply as a digital technique, my research situates it in the continuum of projected moving-image installation artwork. To do this, I examine projection mapping’s screen, narrative, and surrounding space—the constituents of all projected moving-image installation art—through the lenses of surface and depth. In addition to considering cinematic frames, I analyse these traits through artistic lenses such as painting, site-specific art, and architecture to investigate how projection mapping reconfigures the constituents that comprise all screen-based projected moving-image works. In so doing, I define the ways which projection mapping develops its distinctive relationship among these constituents. I conducted three projects in a cyclical developmental process using a reflective methodology derived from case study research: defining the question, recording the process, analysing, and reflecting. My practices as case studies are integral parts of this thesis investigation of how projection mapping generates a distinctive relationship. This study aims to contribute to the body of knowledge about an under-researched area, projection mapping, by providing an in-depth conceptual and practical analysis of this medium. The knowledge resulting from the research is embodied in findings from contextual reviews and original artworks produced as case studies.

Résumé :
Mask Projection Stereolithography (MPSLA) is a high resolution manufacturing process that builds parts layer by layer in a photopolymer. In this research, a process planning method to fabricate MPSLA parts with constraints on dimensions, surface finish and build time is formulated. As a part of this dissertation, a MPSLA system is designed and assembled. The irradiance incident on the resin surface when a given bitmap is imaged onto it is modeled as the Irradiance model . This model is used to formulate the Bitmap generation method which generates the bitmap to be imaged onto the resin in order to cure the required layer. Print-through errors occur in multi-layered builds because of radiation penetrating beyond the intended thickness of a layer, causing unwanted curing. In this research, the print through errors are modeled in terms of the process parameters used to build a multi layered part. To this effect, the Transient layer cure model is formulated, that models the curing of a layer as a transient phenomenon, in which, the rate of radiation attenuation changes continuously during exposure. In addition, the effect of diffusion of radicals and oxygen on the cure depth when discrete exposure doses, as opposed to a single continuous exposure dose, are used to cure layers is quantified. The print through model is used to formulate a process planning method to cure multi-layered parts with accurate vertical dimensions. This method is demonstrated by building a test part on the MPSLA system realized as a part of this research. A method to improve the surface finish of down facing surfaces by modulating the exposure supplied at the edges of layers cured is formulated and demonstrated on a test part. The models formulated and validated in this dissertation are used to formulate a process planning method to build MPSLA parts with constraints on dimensions, surface finish and build time. The process planning method is demonstrated by means of a case study.

Résumé :
Thanks to miniaturization of display technologies, the recent years have seen the emergence of a new generation of mobile devices containing multiple displays. They are identified as Mobile Multi-Display Environments (MMDEs), building on previous work in the field of Multi-Display Environments. This doctoral work presents the first exploration and classification of this research space. In particular, I identify the case of projection-screen MMDEs, mobile devices containing both projection and screen technologies. The dissertation address the following thesis: Providing re-configurability of displays' relative placements in the heterogeneous MMDE and providing interaction using kinaesthetic cues and spatial memory, users can manage complex and highly cognitively charged tasks as well as complex information management across multiple displays. To support this thesis, the dissertation answers research questions around the possibility of synchronous use of the displays given their inherent technological and physical disparities; the optimal relative positioning of the displays; the use of the mobile-projection unit as a secondary display and the projection spaces available around the user. The contributions of this work are multiple, the main contributions are: case studies evaluating and demonstrating the usefulness of synchronous use of the multiple displays; design guidelines for MMDEs; novel interaction techniques and scenario of use; a mathematical model of perceived depth in the mobile environment; and a series of prototypes and experiments that have been designed to support this work. The dissertation shows that multiple displays can be used synchronously to improve the device's capabilities in heterogeneous projection-screen MMDEs so users can perform complex tasks across both displays. This dissertation's vision is that mobile devices with multiple displays can become as useful and as widespread as their fixed MDEs. The results presented in this dissertation further the knowledge of MMDEs.

Texte intégral
Résumé :
Head mounted projection display (HMPD) technology, as an alternative to conventional head mounted displays (HMD), offers a potential of designing wide field-of-view (FOV), low distortion optical see-through HMDs (OST-HMDs). Existing HMPD designs, however, suffer from problems of low luminance and low image resolution, which limits the applications of such information displays for the scenarios which require high luminance and high image fidelity. The design of a polarized head mounted projection display (p-HMPD) was recently proposed to overcome the challenge of low luminous efficiency in existing HMPD designs. Polarization management was employed to reduce the light loss caused by beamsplitting in an HMPD.The work in this dissertation focuses on the development and evaluation of an SXGA resolution, high efficiency p-HMPD system. The main contributions are as follows. First, the key elements in the polarization management scheme of a p-HMPD were selected and their polarization performances were characterized by measuring their Mueller matrices, based on which the overall display performance of a p-HMPD was analyzed.Second, based on a pair of ferroelectric liquid-crystal-on-silicon (FLCoS) microdisplays, a compact illumination unit and a light-weight projection system were designed, from which a p-HMPD prototype was built. Following the prototype implementation, a series of calibrations were performed to obtain correct color presentation, desired focusing setting, and optical system characteristics necessary for achieving accurate registration between virtual objects and their counterparts in the real world.Third, the imaging properties of a retroreflective screen which is an essential part of a p-HMPD or HMPD were studied and its effects on the image resolution of an HMPD system were further characterized.Finally, the performance of the system was evaluated through two objective user experiments, including a visual acuity assessment and a depth perception accuracy assessment.

Texte intégral
Résumé :
Similar projectile point types were used by groups living over a wide geographic region in central and southern Arizona and southwestern New Mexico during the thirteenth and fourteenth centuries A.D. Substantial changes that occurred in southeastern Arizona at this time include population aggregation, the arrival of northern migrant groups, and an increase in obsidian use. An analysis focusing on two sub-regions, the Tucson Basin and the San Pedro Valley, was conducted to explore how social, technological and environmental factors influenced projectile point technology during the Classic period (A.D. 1150–1450) in southeastern Arizona. Projectile point metric and morphological attributes and obsidian source data were used for comparisons within both of the sub-regions. Despite differences in social relations, obsidian exchange networks, and access to large game, comparisons between sites in the northeastern and northwestern Tucson Basin did not reveal significant differences in projectile point types. However, a good deal of variation in base morphology is evident regardless of type among the Tucson Basin sites. Projectile points from Kayenta enclaves in the Lower San Pedro Valley are overwhelmingly made of obsidian, but do not possess significantly different attributes from those used by local groups. Notable variation was seen in the small sample from the Upper San Pedro Valley, which may be attributed to the lack of influence from groups living to the north. Overall, the similarities in projectile point forms correspond with the growth of social networks during the Classic period. Although the small size of these points restricts their usefulness for signaling group identity, variation in base morphology, serrated blade edges, and other small details may continue to inform on the learning traditions or cultural preferences of groups in the region. Future research should expand the study area to include the Upper Gila region of New Mexico, where groups were living close to the extensive Mule Creek obsidian source.

This thesis is an exploration towards an alternative design approach for a public housing in Malaysia. It stems from a conviction that the design of public housing should be based on the lifestyles and ways of living of the people it is intended for. Since the Malaysian people are composed of three diverse cultures: Malay, Chinese, and Indian, this thesis proposes a participatory approach which allows each group to accommodate their cultural needs in the design of their dwelling places. Recognizing that public and communal activities are very much a part of the living environment, the thesis attempts to accommodate these activities into the design process. Because each of the three cultures has different ways and needs, the design of both private dwellings and public/communal spaces is based on the supports concept, which is organized around a system of frameworks. This thesis is the second part of a two part work: Part I is a research of the various types of dwellings: traditional, squatter, and public housing; to discover the important principles and elements that persist in all the dwelling types shared by Malays, Chinese and Indians. Part II is a design projection of those principles for a participatory housing project in Kuala Lumpur, involving four of the thirty families surveyed in Part I research. The design exercise includes exploring various transformation possibilities to produce a whole range of variations that satisfy the needs of the diverse Malaysian cultures. Note: Part I and Part II are documented separately into a S.M.Arch.S and M.Arch theses respectively. Each document is a complete, independent thesis, but very much interrelated. Therefore, it is recommended that they be read in sequence.

Halogen lamps are mostly applied as a light source to the traditional lamp for medical treatment due to its proper color temperature, but it has its disadvantages such as ultraviolet rays and infrared rays which will be harmful to the patients and faculties in the hospitals under long-term exposure. Consequently, using light emitting diode(LED) as a new light source instead of the traditional halogen lamp will be the trend of the future. The purpose of this study is to design a projective LED dental lamp that can achieve the goals of 200mm×100mm for light shape and 11000lux illuminance energy by using the optics simulation software, LightTools. Firstly, a single LED lamp module with a high focusing hollow tubular light guide structure was designed and developed comparing with the solid light guide structure used in many commercial projective dental lamp, the hollow tubular light guide structure can decrease illuminance energy lose due to the absorption by tube material. Because the required objective light shape could not be achieved by using the designed light guide structure only, so a lens component was adopted and designed in order to shrink the output light shape to the required size. Finally, through the specific arrangement of position and angle of each LED lamp module, a projective LED dental lamp with 9 LEDs lamp modules which conform with the required illuminance energy was proposed.

Résumé :
The subject of the study is the emerging practice of landscape design, which aims to provide operational solutions using an interdisciplinary approach and a systemic vision of the functioning of the urban environment, going by the name of Landscape Infrastructure. The research stems from the need to understand what this new design typology consists of and what the role of Landscape Infrastructure projects, in the processes of transformation and creation of cities, is today. Research shows that infrastructure, historically the main engine of growth and improvement in urban development, has become, in the contemporary, global city, a means through which a new connotation to the foundations of the city can be given. In both types of design identified (Infrastructure as Landscape, Landscape as Infrastructure) the Landscape Infrastructure project is a powerful tool for generating new public spaces and increasing urban resilience. By pushing back the limits and giving more scope for the potential of Landscape Infrastructure projects, they should take on an even more structural role in the development of new urban landscapes, thereby enriching the sphere of urban planning with tools, techniques and practices relevant to the construction and transformation of open spaces and providing a suitable response to the social and environmental changes of our time.

Light art is a trend in recent years. Light art festivals and light artists are well known to the public. Projection mapping is one of the important techniques in light art. It preserves the texture and features of the projected objects. Unlimited possibilities are derived from this special form of art. The researcher found that many of the large scale projection mapping projects required expensive equipment and cost a lot of money. The limitation restricts the population of projection mapping. The main purposes of this research are: (1) analysis of domestic and foreign projection mapping cases, (2) explore the application and diversity of projection mapping, (3) test and explore visual effects in projecting mapping with affordable hardware and equipment, and (4) to crate practical projection mapping shows and conclude experiences. Experience is analyzed and conducted to design principles. Three experiments of non-planar projection mapping on real objects are designed and evaluated for different scenarios including promotion with live shows of plaster statues, traditional lion masks combined with light show and animation effects projected on dolls. In addition to the of explanation of the production process, the problems and difficulties encountered are also discussed and analyzed. The researcher wish the final result can be a step forward to practical cases in the real world and non-planar projection mapping can be more diversified and popular in the near future.

Résumé :
Abstract The Photographic and Spatial Survey Method for Video Projection Jeffrey Paul Kurihara, M.F.A. The University of Texas at Austin, 2013 Supervisor: Richard M. Isackes The process and practices that are described in this document were used in several realized video installation projects over the course of 2011-2013. These installations all encompassed the use of Architectural Video Projection Mapping techniques to create transformative animated video projections upon the pre-existing architecture of multiple locations. The process used to achieve this required the integration of multiple practices to obtain and translate specific spatial data to be used in the artistic content creation process. Particular to this method uses a photographic and spatial survey to map the video content accordingly to the architecture of the space. The projects included an installation on a building facade for the Art Alliance Austin’s Holiday Stroll in 2011, another installation on the architecture of an interior wall of a museum space for an event at the Austin Museum of Art in 2013, a site-specific musical theater piece called Almost Invincible in the University of Texas Co-op’s Cohen New Works Festival 2013, and multiple stages of a live music venue named Cheer-up Charlie’s in Austin, Texas form 2011 to 2013.
