Dans cette thèse, nous proposons de nouvelles approches et processus de conception pour créer et produire des plates-formes robotiques dont le contrôle et la morphologie peuvent être explorés et expérimentés librement dans le monde réel, tout en assurant une dissémination directe dans le milieu académique. Ainsi cette thèse adresse deux questions fondamentales dans le processus de recherche scientifique en robotique:1. Comment peut on étudier systématiquement et efficacement l’impact des propriétés morphologiques du corps d’un robot humanoïde pour l’acquisition et le contrôle de savoir-faire sensorimoteurs, ainsi que de capacités d’interactions physiques et sociales avec l’humain ?2. Comment peut on produire des contributions scientifiques en robotique qui soient réellement reproductibles et directement réutilisables, tout en exposant les moindres détails des expérimentations ? Ainsi notre approche propose de nouvelles méthodes de conception et de production, et ce, pour tous les aspects technologiques d’un robot (mécanique, actionneur,électronique, logiciels, distribution). En particulier, ces méthodes reposent sur l’impression 3D pour toutes les pièces mécaniques, un environnement Arduino pour l’acquisition des capteurs, une bibliothèque Python appelée pypot pour le contrôle proposant un API intuitive et enfin la distribution de tout notre travail sous des licences open source.En utilisant cette méthodologie, nous avons créé le robot Humanoïde Poppy, un robotlow-cost, entièrement modulaire et imprimé en 3D. Ce robot est diffusé sous licence open source et tous les fichiers sont facilement accessibles sur le dépôt GitHub du projet: https://www.github.com/poppy_project/.Nous expérimentons l’utilisation de ce robot pour plusieurs applications. Tout d’abord, comme un outil scientifique où nous montrons que Poppy peut être facilement et rapidement modifié, que ce soit pour explorer le rôle de la morphologie ou pour être adaptés à différentes configurations expérimentales. Basé sur ce travail, mais d’un autre point de vue, nous étudions aussi l’impact potentiel d’une telle plate-forme pour des applications éducatives et artistiques.

This thesis suggests novel approaches and design processes to create and produce robotic platforms, the control and morphology of which can be freely explored through experimentation in the real world, that are easy to diffuse and reproduce in the research community. Especially, this alternative design methodology is driven by the desire to:• freely explore morphological properties,• reduce the amount of time required between an idea and its experimentation on an actual robotic platform in the real world,• makes experiments that should be easy to do, actually easy to do,• make the work easily reproducible in any other lab,• keep the work modular and free to use in accordance with open source principles,so it can be reused and extended for other projects.Our approach follows novel design methods for both design and production, for all technological aspects of the robot (i.e. mechanics,…

▼ Open Source Hardware (OSHW) is a concept where hardware designs are shared for everyone to use, modify and build upon. This have become a widespread phenomenon in the microcontroller industry and created an ecosystem where users and companies produce various “derivatives” or alternative designs based on existing OSHW. This research explores this phenomenon of derivative development between users and producers and how this affects innovation, by exploring three case studies of user developed derivatives and interviews with producers and various people with OSHW background. This thesis found that this ecosystem to be dependent on Open Source and leverages the interest of users motivation to innovate and producer support. Furthermore, eight different factor were discovered that derivative development affecting innovation. (1) <em>Openness & Transparency </em>allows the user to innovate without fearing consequences of IP infringement and establishing trust. The transparency also increases the chances for the users to become innovators, as it facilitates the understanding of products, through the documentations and information sharing. (2) Support from producers facilitates users’ ability to design and innovate and was found crucial for the emergence of derivative designs. (3) Amplified Motivation through personal interest has a high impact in the innovation of open microcontrollers. (4) Market diffusion through low-cost ways of sharing and diffusing designs. (5) Market expansion increasing the number of derivative development can affect the resources used by producers in their development process. (6) Product improvements are affected, because of the vast feedback provided by the community, which can lead to through the discovery of usage in fields, product functionality. This increases the quality of the product and allows OSHW producers to stay competitive. (7) Collaboration can affect innovation by the collaborations with derivative projects and businesses. (8) Brand and Marketing is affecting by the number of users that use producers’ products for user-innovators development of derivative designs.

Mestrado em Software de Código Aberto

A presente dissertação de mestrado enquadra-se no âmbito da necessidade crescente das empresas em formar os seus colaboradores em áreas de interesse para os objetivos organizacionais, nomeadamente formação interna de quadros organizacionais. Procura-se ainda um ponto centralizado de distribuição desses cursos e-learning, sem os custos com licenciamento ou hardware de alto custo. Por outro lado, temos a formação de pessoas onde o acesso à internet não é possível. Um exemplo poderá ser a formação de crianças ou adultos, em países subdesenvolvidos com dificuldades de acesso à Internet ou mesmo a sua inexistência. Com base em revisão de literatura esta dissertação apresenta um modelo conceptual de e-learning capaz de responder as necessidades dos vários stakeholders de elearning em contexto organizacional. O modelo contempla três partes: hardware open source, software open source e curso. É aqui descrito o trabalho empírico realizado com a validação do modelo proposto. A presente dissertação desenvolve assim um modelo que permite distribuir massivamente formação à distância para contextos organizacionais de empresas com colaboradores deslocalizados.

This master thesis is contextualized in the growing need to promote training courses for organizational goals. Particularly in internal training, organizations aim to increase their teams’ knowledge, trying to reduce costs while still maintaining a centralized distribution point of these courses, and e-learning, without costs of licensing or expensive hardware. The need to train people where Internet access is not possible, an example might be the education of children and adults in developing countries with limited access to the Internet or even their absence. Based in literatures review this thesis presents an e-learning conceptual model capable of satisfying needs of the various stakeholders in an organizational context. The conceptual model is based upon three parts: hardware open source, software open source and course. Here it is described the conducted empirical work for validating the proposed model. This master thesis develops a distance massive learning model for training in organizational contexts.

▼ A better understanding of Open Source Innovation in Physical Product (OSIP) might allow project managers to mitigate risks associated with this innovation model and process, while developing the right strategies to maximise OSIP outputs. In the software industry, firms have been highly successful using Open Source Innovation (OSI) strategies. However, OSI in the physical world has not been studied leading to the research question: What advantages and disadvantages do organisations incur from using OSI in physical products? An exploratory research methodology supported by thirteen semi-structured interviews helped us build a seven-theme framework to categorise advantages and disadvantages elements linked with the use of OSIP. In addition, factors impacting advantage and disadvantage elements for firms using OSIP were identified as: „h Degree of openness in OSIP projects; „h Time of release of OSIP in the public domain; „h Use of Open Source Innovation in Software (OSIS) in conjunction with OSIP; „h Project management elements (Project oversight, scope and modularity); „h Firms. Corporate Social Responsibility (CSR) values; „h Value of the OSIP project to the community. This thesis makes a contribution to the body of innovation theory by identifying advantages and disadvantages elements of OSIP. Then, from a contingency perspective it identifies factors which enhance or decrease advantages, or mitigate/ or increase disadvantages of OSIP. In the end, the research clarifies the understanding of OSI by clearly setting OSIP apart from OSIS. The main practical contribution of this paper is to provide manager with a framework to better understand OSIP as well as providing a model, which identifies contingency factors increasing advantage and decreasing disadvantage. Overall, the research allows managers to make informed decisions about when they can use OSIP and how they can develop strategies to make OSIP a viable proposition. In addition, this paper demonstrates that advantages identified in OSIS cannot all be transferred to OSIP, thus OSIP decisions should not be based upon OSIS knowledge.

▼ Pour préserver leur modèle économique, les entreprises ont longtemps protégé leurs processus d’innovation par des brevets. L’« open source hardware » est, au contraire, un processus collaboratif de développement de produits, où les plans de conception et « secrets » de fabrication sont accessibles à tous. La barrière entre concepteurs et consommateurs s’estompe, grâce aux outils de fabrication digitale, comme les imprimantes 3D ou les découpeuses lasers accessibles via des Fab Labs ou des Maker Spaces permettant aux citoyens de créer et de tester des produits beaucoup plus facilement. Partant d’un phénomène isolé, il existe maintenant 1200 Fab Labs dans 100 différents pays organisés en réseau, « the Fab City Network », dont le but est d’aider les villes à produire 50% des ressources qu’elles consomment d’ici quarante ans.Dans ce contexte, construire un drone pour dépolluer les océans, une ruche connectée, ou un filtre à eau en « Open Source Hardware » (OSH) vise à créer des solutions de manière plus rapide, efficace et à moindre coût. De plus, ces innovations sont gardées volontairement libres de droit. Elles constituent un « bien commun digital », une réserve de connaissances disponible sur Internet via des plateformes numériques. Selon Elinor Ostrom, qui a reçu le prix Nobel d’économie en 2009 « le défi de la génération actuelle est de garder les voies d’accès aux connaissances ouvertes ». Sans atteindre le succès des initiatives en Open Source dans le secteur des logiciels informatiques, ces initiatives n’ont cessé de se propager.Or, comment développer un modèle économique durable avec des innovations qui ont été co-construites et sont partageables par tous ? Nos questions de recherche sont les suivantes : 1) comment rentabiliser la création de valeur produite en OSH ? ; 2) comment étendre cette création de valeur à un ensemble de parties prenantes ? 3) dans le contexte de l’OSH quels sont les facteurs d’adhésions autour de ces modèles économiques ?L’OSH ne s'agit pas d'un phénomène propre à un seul secteur, entreprise ou territoire mais une transformation beaucoup plus globale. Pour chercher à comprendre les conditions nécessaires à la survie et à la montée en puissance de ce phénomène, nous avons mené une étude qualitative multiniveaux qui nous permettait d’étudier les niveaux communautaires, d’entreprise, et d’écosystème territorial, à la fois.La collection de données s’est faite en trois étapes successives. Dans un premier temps, des entretiens qualitatifs ont été menés auprès de vingt-trois initiatives issues de « l’Observatoire de l’Open Source Hardware ». Celles-ci devaient, bien entendu, correspondre à nos critères de recherche, à savoir le développement de produits mécatroniques ou textiles complexes et étiquetés ouverts par leur communauté. Puis, nous avons mené une étude de cas sur quatre acteurs du secteur automobile pour étudier leur réaction face à l’OSH issu de communautés d’innovation. L’étape finale consistait à mener une étude empirique sur les acteurs dans l’écosystème d’innovation d’OSH de la… Advisors/Committee Members: Evrard Samuel, Karine (thesis director).

▼ The ability to control the biochemical processes of the cell is fundamental to the goals of synthetic biology. This control implies the ability to specify the spatial, temporal, and amount of gene expression and protein activity in individual cells and populations. Hardware, wetware, and methods which advance the ability to control these processes then increase the ability and precision of researchers to perturb and study natural biological systems and of engineers to build useful biological systems and products. In optogenetics, researchers use light and genetically encoded photoreceptors to control biological processes with unmatched precision. However, outside of neuroscience, the impact of optogenetics has been limited by a lack of user-friendly, flexible, accessible hardware. In the first portion of this work, we engineer the Light Plate Apparatus (LPA), a device that can deliver two independent 310 to 1550 nm light signals to each well of a 24-well plate with intensity control over three orders of magnitude and millisecond resolution. Signals are programmed using an intuitive web tool named Iris. All components can be purchased for under \400 and the device can be assembled and calibrated by a non-expert in one day. We use the LPA to precisely control gene expression from blue, green, and red light responsive optogenetic tools in bacteria, yeast, and mammalian cells and simplify the entrainment of cyanobacterial circadian rhythm. The LPA dramatically reduces the entry barrier to optogenetics and photobiology experiments. In the second portion of this work, we describe a general method for independently controlling population mean and noise of cellular protein copy number by convolution of gene expression distributions. In this method, a gene is simultaneously expressed from both a low- and high-noise source, resulting in summation of the gene products within cells and convolution of the gene expression distributions within the population. By tuning the amount and ratio of expression from each source, the mean and noise, respectively, of the convolution can be independently controlled. In principle, this method can be applied in any host using any two sources of low- and high-noise gene expression. We demonstrate this method in it{Escherichia coli} by engineering and co-expressing a high-noise, LuxR-based, positive feedback transcriptional unit, and a low-noise, TetR-based, transcriptional unit without feedback. By exposing cells to different amounts and ratios of inducer we can independently control mean and noise in gene expression over a “dynamic area” of 1.1 with a maximum fold-change in CV of 6.9; performance metrics we propose and describe in this study. A mathematical model for mean and noise of a two-gene convolution accurately captures the observed behavior and can be used to predict mean and noise from inducer concentrations. Finally, we use our method to measure the effect of variability in the expression of a toxin on bacterial growth dynamics. We predict that the fraction of cells in the… Advisors/Committee Members: Tabor, Jeff (advisor).

▼ Microalgae are photosynthetic organisms considered to be one of the most promising high-value chemicals and biofuel-producing organisms. However, there are several challenges for the widespread implementation of industrial processes using microalgae. The work presented in this dissertation proposes solutions to the different challenges involving the use of microalgae as microbial cell factories. To investigate the application of anaerobic digestion as a way to generate nutrients for microbial growth, salmon offal was used as substrate for anaerobic digestion, and soil from a flooded run-off pond on the Virginia Tech campus in Blacksburg, VA. A fast reduction in volatile solids and the short-chain fatty acid production profile is favorable for the growth of microalgae. A novel algae strain Scenedesmus sp. A6 was isolated from a decorative waterfountain in a hotel in Madison, IN. Mixotrophic growth trials were conducted using wastewater from the salmon offal digestion, that demostrated the A6 isolate grows six times faster in the wastewater then autotrophically. Bioassays of ethanolic cell extracts of A6 cultures demonstrated antimicrobial activity against E. coli cells at concentrations above 50 µg/ml. Genome sequencing and assembly revealed multiple copies of genes involved with acetate and ammonia metabolism, and several genes involved with secondary metabolite synthesis. An alternative to the high capital investment of photobioreactors for the cultivation of microalgae is the use of open-source and open-hardware bioreactor controller. Here, the concept of an open-hardwate bioreactor control called ``BioBrain'' is introduced. The BioBrain device is based on the Arduino Mega micro-controller board, and is capable of monitoring and controlling culture conditions during simple strain characterization studies, with an estimated construction cost of less than $800 USD. Finally, a new primer design tool for the ligation-independant cloning technique 𝜆-PCR was developed called lambdaPrimeR. The contributions of this work are the discovery and development of different tools that can overcome the challenges of the use of microalgae as microbial cell factories in industrial processes.

▼ Big science infrastructures are confronting increasing demands for public accountability, not only within scientific discovery but also their capacity to generate secondary economic value. To build and operate their sophisticated infrastructures, big science often generates frontier technologies by designing and building technical solutions to complex and unprecedented engineering problems. In parallel, the previous decade has seen the disruption of rapid technological changes impacting the way science is done and shared, which has led to the coining of the concept of Open Science (OS). Governments are quickly moving towards the OS paradigm and asking big science centres to "open up” the scientific process. Yet these two forces run in opposition as the commercialization of scientific outputs usually requires significant financial investments and companies are willing to bear this cost only if they can protect the innovation from imitation or unfair competition. This PhD dissertation aims at understanding how new applications of ICT are affecting primary research outcomes and the resultant technology transfer in the context of big and OS. It attempts to uncover the tensions in these two normative forces and identify the mechanisms that are employed to overcome them. The dissertation is comprised of four separate studies: 1) A mixed-method study combining two large-scale global online surveys to research scientists (2016, 2018), with two case studies in high energy physics and molecular biology scientific communities that assess explanatory factors behind scientific data-sharing practices; 2) A case study of Open Targets, an information infrastructure based upon data commons, where European Molecular Biology Laboratory-EBI and pharmaceutical companies collaborate and share scientific data and technological tools to accelerate drug discovery; 3) A study of a unique dataset of 170 projects funded under ATTRACT -a novel policy instrument of the European Commission lead by European big science infrastructures- which aims to understand the nature of the serendipitous process behind transitioning big science technologies to previously unanticipated commercial applications; and 4) a case study of White Rabbit technology, a sophisticated open-source hardware developed at the European Council for Nuclear Research (CERN) in collaboration with an extensive ecosystem of companies.

Foi desenvolvido um protótipo de hardware de sistema de monitoramento meteorológico como tecnologia aberta e livre e voltado para a ciência cidadã, chamado de Estações Meteorológicas Modulares (EMM). Foram considerados critérios de acessibilidade dos materiais e facilidade de modificação no desenvolvimento do projeto. Todos os programas utilizados no desenvolvimento são softwares livres. Um dos elementos desenvolvidos, a placa de controle das EMM, possibilita medir diferentes parâmetros meteorológicos, além de realizar o registro dados e envio para um servidor. Também possibilita a inclusão de novos sensores. Por todos esses fatores, é considerada satisfatória quanto a sua funcionalidade. A estrutura mecânica das EMM atingiu um patamar de preço acessível a indivíduos e organizações como escolas e associações de moradores de bairro, e apresenta fácil adaptabilidade a diferentes condições de instalação. O custo total do sistema ficou abaixo de alternativas proprietárias amadoras e significativamente abaixo de alternativas proprietárias profissionais. Soluções acessíveis para alguns elementos da EMM ainda requerem testes mais aprofundados. Parte das ferramentas utilizadas na fabricação da placa de controle ainda carece de maior disseminação junto à sociedade para acessibilizar o sistema das EMM. Os registros de desenvolvimento do trabalho foram feitos em forma de documentação aberta por meio de cadernos de laboratório abertos. As atividades de fabricação, montagem e instalação das EMM foram feitas seguindo métodos colaborativos chamados de Encontros de Fabricação Colaborativa e Mutirões das EMM. O resultado deste trabalho, unindo as documentações, os registros dos métodos colaborativos de fabricação, montagem e instalação e as consolidadas oficinas do projeto, é sintetizado no Guia da Comunidade EMM. Este é um roteiro para quem quiser fazer parte e ampliar uma rede de monitoramento ambiental colaborativo com as EMM, e é baseado em atividades educacionais para compreensão dos diferentes elementos da ferramenta e para a emancipação tecnológica. Uma das EMM foi comparada com uma estação automática oficial do Instituto Nacional de Meteorologia (INMET). Nessas comparações, as medidas de temperatura e pressão atmosférica apresentaram diferenças menores do que a acurácia dos sensores, enquanto a umidade relativa do ar apresentou uma diferença acima da acurácia do sensor. Este foi um primeiro passo de validação das EMM.

It was developed the hardware prototype of a meteorological monitoring system as free and open source hardware with focus on citizen science. The system is called Estações Meteorológicas Modulares (EMM, from Portuguese Modular Meteorological Stations). Affordability and reachability of materials and ease of remix were criteria considered in the development of this project. All the programs used in the development are free software. One of the elements developed, the control board of the EMM, is considered satisfactory in terms of: the parameters it enables to measure, the functionalities of communication and…

▼ Human Development is not a term used in casual conversation, it describes the current approach used by large aide international development organizations like the United Nations; but most people are familiar with the terms “emergency relief” and “humanitarian intervention”. Emergency relief focuses on providing assistance to save lives, alleviate suffering, or protect populations; while human development uses various societal levers to improve living conditions. The United Nation has been publishing an annual report on human development since 1990 (UNDP 1990), and it is widely recognized as a consistent measure of global living conditions. Development strategies revolve around a transfer of something valuable to an aided population: education, vaccination, fertilizers, etc. In technology-based human development projects, technology artefacts (a medical record computer system, solar electrification systems, irrigation) and related knowledge (education, operation and maintenance instruction) are those valuables being transferred. The benefits of technology are specific to each economy, and dependant on how quickly technology is adapted and integrated in the local economy (Cypher & Dietz 2008). The value of ideas increases to the degree they can be shared with and used by others (Houghton & Sheehan 2000): the more knowledge is diffused and adopted, the greater its value. The success of free and open-source software exemplifies this principle, and a growing number of scholars agree that the model also applies to hardware (Balka et al. 2009; Thompson 2008). This thesis presents research on open source hardware and its knowledge-sharing approach as a means to human development. It presents a model that leverages the collaborative design methodology of open hardware for adoption of artefacts that address pressing “humanitarian technology” needs, for example, in health or education. To achieve this, critical literature reviews on open source and on technology-based human development are first done; the findings from literature are then complemented with the findings from interviews and case studies to model a sustainable deployment strategy for open source use in human development projects. Adopting the human development paradigm defined in the first Human Development Report (“HDR1990”), which aims at three people-centered aspirations: to live a long and healthy life, to be educated and to have access to resources needed for a decent standard of living (UNDP 1990). This thesis research models its deployment strategy using the Soft Systems Methodology (SSM), showing that: (a) open source hardware, like any technology used in development, can magnify effective development programs when used appropriately; (b) Dr. E.F. Schumacher’s appropriate technology principles, and P. Polak’s reinstatement, mesh very well with the open source methodology, as long as required constituents in the aided communities are taken care of (availability of electricity, internet access, technical know-how, etc.); (c) extreme affordability is…

▼ Contrary to submarine control strategies, pilots of Remotely Operated Vehicles (ROVs) remain remote to the vehicle while manoeuvring and manipulating them through their surrounding environments using tele-operation technology and visual feedback interface. However, due to the lack of three-dimensional (3D) information and limitations with quality and the field vision of the cameras, ROV pilots are not always able to observe and identify external hazards purely through visual feedback, especially when ROVs operate in environments littered with obstacles, which can thus result in collisions. To avoid such occurrences, a haptic controller including a tactile user interface was developed for ROVs in order to enhance the operators’ awareness of the working environment and thus improve the performances of the vehicles within such environments. The haptic control technique developed in this project was initially examined within a simulated environment and then applied to control a low-cost open source hardware-based ROV to validate its effectiveness. In the simulation phase, the haptic control interface hardware and software, including the haptic joystick and a novel Artificial Potential Field (APF) technique was developed to assist pilots to safely manoeuvre the simulated ROV through the surrounding environment containing both static and moving obstacles. A robust adaptive control algorithm for the haptic controller was also developed to improve the performance of the haptic control system while maintaining its stability. The proposed technique was then experimentally validated by applying the haptic controller to an observation class ROV, designed and developed for this project using open source hardware and low-cost equipment. To ensure the quality of the ROV’s haptic drive system, a multi-layer Kalman filter and advanced control algorithms, such as adaptive PID and robust model-based algorithms, were designed to estimate the vehicle’s states and to control its surge, yaw, and heave motions based on a host-target control structure. The experimental results show that the host-target control structure was effectively employed to collect data and control the open source hardware-based ROV in real time. Additionally, the host-target structure was able to overcome the limitation associated with the computational power of the microcontroller, allowing the programmers to develop complex algorithms to process the raw data from low-cost sensors and deal with the nonlinear characteristics of the vehicles. The ROV performances observed from both the simulations and the experimental work indicate that the multi-layer Kalman filter and the adaptive PID algorithms provide acceptable state estimation for the ROV and thus assist the pilot in adequately manoeuvring the vehicle. The simulation results show that the proposed APF technique has the ability to model the potential risk presented by both stationary and moving obstacles. The information is fed back and used as reference signals for the force controller incorporated within the…

▼ Starting from the experiences of hackers developing free software and open hardware, this thesis addresses some key and recurrent themes in the field of Science and Technology Studies (STS). It poses the question: how are technologies conceptualised, constructed and used in ways that render some aspects of them transparent, while leaving others opaque? This question is complicated by the fact that what is visible and transparent to some will remain opaque to others, depending on the level of technical expertise commanded. The political implications of this stand at the heart of my inquiry. Since technical know-how is unevenly distributed among groups in society, the same concern can be rephrased as follows: How are relations of power and conflict mediated through technology and relations of technical expertise/ignorance? While trying to address this question, the thesis delves into matters of epistemology. Just as programming skills are required for seeing what is going on behind the computer screen, so theoretically informed reflection can be considered necessary for rendering visible social relations not immediately apparent to the casual eye. Discussion of the actions of hackers is therefore combined in this thesis with discussion of the alternative programmes of research which can be applied to the study of these actions. Two programmes of research in particular receive attention: the critical theory of technology and constructivist science and technology studies (STS). Of these two, the relevance of the former tradition is emphasized and its value for research in the STS field defended. The thesis is composed of four articles and an introductory chapter summarizing and encapsulating my concerns. The first article discusses belief in technological determinism among hackers and how this does not necessarily stand in opposition to political engagement. On the contrary, it is common within hacker politics for contending viewpoints to be articulated in relation to seemingly apolitical narratives about technical neutrality and progress. The second article also deals with antagonistic relations at the heart of processes of technological change. It argues that the punitive actions of law enforcement agencies provide a clear indication of the presence of asymmetrical power relations in technological change through, for example, attempts to suppress filesharing inventions. Hackers are negotiating with legal authorities and the mass media, but also amongst themselves, about how to draw the line between the legitimate users and harmful misusers of technology. The third and fourth articles are based on a case study of a group of Czech hardware hackers who invented a wireless network technology for sending data with visible, red light. The challenges faced by these hardware hackers in their attempts to design technical solutions capable of being built by non-expert users are discussed at length in a theoretically-informed fashion.

▼ Low-cost and open-source gas metal arc welding (GMAW)-based 3-D printing has been demonstrated yet the electrical design and software was not developed enough to enable wide-spread adoption. This thesis provides three novel technical improvements based on the application of mechatronic and software theory that when combined demonstrate the ability for distributed digital manufacturing at the small and medium enterprise scale of steel and aluminum parts. First, low cost metal inert gas welders contain no power monitoring needed to tune GMAW 3-D printers. To obtain this data about power and energy usage during the printing, an integrated monitoring system was developed to measure current (I) and voltage (V) in real-time. The new design of this monitoring system integrates an open source microcontroller and free and open source software on the open-source metal 3-D printer to record the data. Second, the primary obstacle to the diffusion of this technology was that existing slicing software, which determines the toolpath of the printhead was optimized for polymer 3-D printing and inappropriate for printed parts made from metal due to their mechanical strength. Previous prints were accomplished by manually designing the toolpath, which was not practical for real use by an extended userbase. To overcome the problem, the free and open-source slicing software, CuraEngine, was forked to MOSTMetalCura, which supports the needs of GMAW-based metal 3-D printing. The optimized setting for wire feed rate is calculated by the new slicer based on printing speed, bead width, layer height, and material diameter. Previous studies have shown that GMAW-based metal 3-D printing is capable of fabricating parts with good layer adhesion and porosity. However, this preliminary work lacked demonstrations of real-world applications. Finally, in this work, the practical applications of open-source GMAW-based metal 3-D printing are well demonstrated for both developing world and developed world applications including: 1) fixing an existing part by adding on a 3-D metal feature, 2) creating a product using the substrate as part of the component, 3) 3-D printing useful objects in high resolution, 4) near net shape objects and 5) making an integrated product using a combination of steel and polymer 3-D printing. The results prove that low-cost and open-source GMAW-based metal 3-D printing is ready for distributed manufacturing by SMEs and adequate for a wide range of applications.

This doctoral thesis aims firstly to study the existing architectures for wireless sensors networks nodes’ hardware design and to identify their limitations, constraints and difficulties, and secondly to propose and establish of a novel architecture that can combine the advantages of existing architectures and ensure the elimination of any limitation and constraints in order to design hardware for nodes deployed in real-world application s in the harsh environment of agriculture. The methodology to meet the aforementioned aims includes: first the implementation of specific nodes’ hardware design case studies based on: i) the Typical Architecture, ii) the End-Systems Architectures, iii) the Commercial-of-the-Shelf Architectures, and iv) the Open-Source Hardware Architectures in order to identify particular issues per existing architecture; and second, the establishment of a new architecture for hardware design that can ensure the elimination of any issue such as those imposed by the existing architectures and that it can provide the advantages of End-Systems architectures with the benefits of Open-Source Hardware architectures. The results of the doctoral thesis include firstly the identification and presentation of specific constraints and limitations associated with each of the existing architectures of nodes’ hardware design. In particular, the traditional typical architecture appears to be insufficient in integrating new challenging technologies; End-Systems architectures whereas ensure focused solutions with optimized hardware of nodes they impose significant issues regarding scalability, expandability, reusability and high cost and longevity; Commercial-of-the-Shelf (COTS) Architectures on the other hand they found to be highly improper for deployments in real-world agricultural wireless sensors networks’ applications; while the Open-Source Hardware (OSH) architectures whereas they provide extensive degree of freedom in expandability, scalability, and reusability, they suffer from poor reliability, low energy efficiency, anarchy in expansion, and low robustness for operating in the harsh agricultural environment. Secondly, results include the proposition of a new architecture, namely the SensoTube. This architecture is based on the establishment of a conceptual abstraction of seven distinct functional layers with which any wireless sensors networks nodes hardware can ve studied, modeled, described, designed and implemented in a very comprehensive way. The SensoTube is described in detail. Specifically, its printed-circuit board reference model of implementation is given along with the introduction of novel mechanisms for signals and communications management, energy management, and management of the programming and debugging of microcontrollers of the nodes which allow for inter-layer services. Ultimately, the proposed architecture is evaluated and tested according particular design case studies.

▼ This research aims to make science more accessible through the use of open source 3-D printers. A new control system for CNC machines in general and 3-D printers specifically, is developed and presented that enables web-based control of 3-D tools from any Internet connected device. The system can be set up and controlled entirely from a web interface. A tool was designed to help apply science to the developing world. The developing world remains plagued by lack of access to safe drinking water. A methodology is provided for the design, development, and technical validation of a low-cost open-source water testing platform. A case study is presented where the platform is developed to provide both colorimetry and nephelometry. This approach resulted in equipment that costs between 7.5 and 15 times less than current commercially available tools. A syringe pump was designed and manufactured using an open-source hardware and software. The design, bill of materials and assembly instructions are available. The cost of the entire system, including the controller and web-based control interface, is on the order of 5% or less of a commercial syringe pump having similar performance. The design should suit the needs of almost any research activity requiring a syringe pump. A low-cost, open source 3-D microscope stage is presented. A RepRap 3-D printer was converted into an optical microscope equipped with a customized holder for a USB microscope. The machine is able to operate with USB or conventional microscopes. The repeatibility is below 2-D microscope stages, but it is adequate for the majority of scientific applications. The stage costs less than 3% to 9% of the closest proprietary commercial stages. A deformation model for PLA was expanded to use a physics based temperature gradient. This generalized the model to 3-D printing in a room temperature environment. Tests confirm that this is a valid model for predicting warpage of thin vertical walls of PLA. Additionally, the effect of annealing was examined. It was found that at a temperature of 50°C, no shrinkage or crystallization takes place, but at 90°C the plastic rapidly crystallizes to around 20% crystallinity.

▼ While it is generally accepted that environmental data are critical to understanding environmental phenomena, there are yet improvements to be made in their consistent collection, curation, and sharing. This thesis describes two research efforts to improve two different aspects of hydrologic data collection and management. First described is a recipe for the design, development, and deployment of a low-cost environmental data logging and transmission system for environmental sensors and its connection to an open source data-sharing network. The hardware is built using several low-cost, open-source, mass-produced components. The system automatically ingests data into HydroServer, a standards-based server in the open source Hydrologic Information System (HIS) created by the Consortium of Universities for the Advancement of Hydrologic Sciences Inc (CUAHSI). A recipe for building the system is provided along with several test deployment results. Second, a connection between HydroServer and HydroShare is described. While the CUAHSI HIS system is intended to empower the hydrologic sciences community with better data storage and distribution, it lacks support for the kind of “Web 2.0” collaboration and social-networking capabilities that are increasing scientific discovery in other fields. The design, development, and testing of a software system that integrates CUAHSI HIS with the HydroShare social hydrology architecture is presented. The resulting system supports efficient archive, discovery, and retrieval of data, extensive creator and science metadata, assignment of a persistent digital identifier such as a Digital Object Identifier (DOI), scientific discussion and collaboration around the data and other basic social-networking features. In this system, HydroShare provides functionality for social interaction and collaboration while the existing HIS provides the distributed data management and web services framework. The system is expected to enable scientists, for the first time, to access and share both national- and research lab-scale hydrologic time series in a standards-based web services architecture combined with a social network developed specifically for the hydrologic sciences.These two research projects address and provide a solution for significant challenges in the automatic collection, curation, and feature-rich sharing of hydrologic data.

▼ The particular characteristics and affordances of technologies play a significant role in human experience by defining the realm of possibilities available to individuals and societies. Some technological configurations, such as the Internet, facilitate peer-to-peer communication and participatory behaviors. Others, like television broadcasting, tend to encourage centralization of creative processes and unidirectional communication. In other instances still, the affordances of technologies can be further constrained by social practices. That is the case, for example, of radio which, although technically allowing peer-to-peer communication, has effectively been converted into a broadcast medium through the legislation of the airwaves. How technologies acquire particular properties, meanings and uses, and who is involved in those decisions are the broader questions explored here. Although a long line of thought maintains that technologies evolve according to the logic of scientific rationality, recent studies demonstrated that technologies are, in fact, primarily shaped by social forces in specific historical contexts. In this view, adopted here, there is no one best way to design a technological artifact or system; the selection between alternative designs—which determine the affordances of each technology—is made by social actors according to their particular values, assumptions and goals. Thus, the arrangement of technical elements in any technological artifact is configured to conform to the views and interests of those involved in its development. Understanding how technologies assume particular shapes, who is involved in these decisions and how, in turn, they propitiate particular behaviors and modes of organization but not others, requires understanding the contexts in which they are developed. It is argued here that, throughout the last century, two distinct approaches to the development and dissemination of technologies have coexisted. In each of these models, based on fundamentally different ethoi, technologies are developed through different processes and by different participants—and therefore tend to assume different shapes and offer different possibilities. In the first of these approaches, the dominant model in Western societies, technologies are typically developed by firms, manufactured in large factories, and subsequently disseminated to the rest of the population for consumption. In this centralized model, the role of users is limited to selecting from the alternatives presented by professional producers. Thus, according to this approach, the technologies that are now so deeply woven into human experience, are primarily shaped by a relatively small number of producers. In recent years, however, a group of three interconnected interest groups—the makers, hackerspaces, and open source hardware communities—have increasingly challenged this dominant model by enacting an alternative approach in which technologies are both individually transformed and collectively shaped. Through a in-depth analysis of…

▼ Accurate forecasts of weather and climate will become increasingly important as the world adapts to anthropogenic climatic change. Forecasts' accuracy is limited by the computer power available to forecast centres, which determines the maximum resolution, ensemble size and complexity of atmospheric models. Furthermore, faster supercomputers are increasingly energy-hungry and unaffordable to run. In this thesis, a new means of making computer simulations more efficient is presented that could lead to more accurate forecasts without increasing computational costs. This 'scale-selective reduced precision' technique builds on previous work that shows that weather models can be run with almost all real numbers represented in 32 bit precision or lower without any impact on forecast accuracy, challenging the paradigm that 64 bits of numerical precision are necessary for sufficiently accurate computations. The observational and model errors inherent in weather and climate simulations, combined with the sensitive dependence on initial conditions of the atmosphere and atmospheric models, renders such high precision unnecessary, especially at small scales. The 'scale-selective' technique introduced here therefore represents smaller, less influential scales of motion with less precision. Experiments are described in which reduced precision is emulated on conventional hardware and applied to three models of increasing complexity. In a three-scale extension of the Lorenz '96 toy model, it is demonstrated that high resolution scale-dependent precision forecasts are more accurate than low resolution high-precision forecasts of a similar computational cost. A spectral model based on the Surface Quasi-Geostrophic Equations is used to determine a power law describing how low precision can be safely reduced as a function of spatial scale; and experiments using four historical test-cases in an open-source version of the real-world Integrated Forecasting System demonstrate that a similar power law holds for the spectral part of this model. It is concluded that the scale-selective approach could be beneficially employed to optimally balance forecast cost and accuracy if utilised on real reduced precision hardware.

▼ The Monterey Bay Aquarium Research Institute (MBARI) established the Free Ocean Carbon Enrichment (FOCE) experiment to study the long-term effects of decreased ocean pH levels by developing in-situ platforms [1]. Deep FOCE (dpFOCE) was the first platform, which was deployed in 950 meters of water in Monterey Bay. After the conclusion of dpFOCE, MBARI developed an open source shallow water FOCE (swFOCE) platform located at around 250 meter of water to facilitate worldwide shallow water experiments on FOCE [1][2]. A shallow water platform can be more ubiquitous than a deep-water platform as shallow water instruments are less expensive (as it does not have to be designed to withstand the pressure at deep ocean depths) and more easily deployed (they can be deployed right along the coast). The swFOCE experiment is an open source platform, and MBARI has made the plans available online to anyone interested in studying shallow water carbon enrichment. There is a gateway node what is connected to four sensor nodes within the swFOCE. In order to test the sensor node individually, an idea of designing an Oceanographic Instrument Simulator is purposed. The Oceanographic instrument simulator (OIS), described in this paper provides the means for MBARI engineers to test the swFOCE platform without attaching the numerous and expensive oceanographic instruments. The Oceanographic Instrument Simulator simulates the various scientific instruments that could be deployed in an actual experiment. The Oceanographic Instrument Simulator (OIS) system includes the designed circuit board, Arduino Due and an SD Card shield. The designed circuit board will be connected to a computer through a USB cable, and be connected to MBARI’s swFOCE sensor node through a serial connection. When a query is given from the sensor node, the Arduino Due will parse the data given from the sensor node, search through the pre-installed data in the SD card and return the appropriate data back to the sensor node. A user can also manually set up the input current through a computer terminal window to control the simulated signals from the PCB. Advisors/Committee Members: Vladimir Prodanov.
