    Dissertação de Mestrado em Engenharia InformáticaCurrently, Information Technology (IT) is a driving factor in the process of globalization and in the innovative use of resources to promote new products and ideas, creating efficient and effective channels to exchange information. Products based upon, or enhanced by, technology are used in nearly every aspect of life in contemporary industrial societies. Business productivity software ensures that organizations have the tools to overcome the challenges of executing on strategy every day and prosper in an increasingly challenging era. IT has been the catalyst for global integration, thus it is hard to imagine a company that dispenses the support of these services. Therefore, IT allows the return of investment of all the logistics businesses, shipping scheduling, procurement of materials and suppliers. The use of IT tools is considered a competitive advantage, taking companies to invest in research and development in order to increase profits, thus influencing their strategy and organizational model. Logistics is the process of planning, implementing, and control the efficient, cost effective flow and storage of raw materials, in-process inventory, finished goods and related information from point of origin to point of consumption, for the purpose of conforming to customer requirements. This project looks at the integration of logistics with IT, since information is a key element of logistics. The dissertation proposal presented in this document has as main goal, the development of a continuous Finished Good (FG) monitoring system, also known as outbound logistics. Given the responsibility and importance of such system different techniques and methodologies are carefully addressed. Techniques necessary to ensure the reliability and the correct organization of information present in the system, as well as a projection for expansion in the near future. An intelligent environment is proposed that is able to track and provide real-time information related to FG in transit. The major focus is that the user should not be forced to actively search for deviations in the supply chain,but be able to pursue other tasks,and still be notified of any change in the transportation process. To develop this work a prototype was devised on which the behaviour and external system interactions were thoroughly tested and validated. The result of the project is a system capable of monitoring FG in transit, as well as provide updated information to the users in order to better predict or assess any deviations.Atualmente, a Tecnologia da Informação (TI) é um fator impulsionador na globalização e no uso inovador de recursos para promover novos produtos e ideias, criando canais eficientes e efetivos para trocar informações. Os produtos baseados ou aprimorados pela TI são utilizados em quase todos os aspetos nas sociedades industriais contemporâneas. O desenvolvimento de software garante que as organizações possuam as ferramentas para superar os desafios diários e prosperam numa era cada vez mais desafiante. A TI tem sido o catalisador da integração global, por isso é difícil imaginar uma empresa que dispense o suporte desses serviços. Assim sendo, possibilita assegurar o retorno do investimento em conjunto com a logística do negócio, agendamento de compras, obtenção de matéria-prima, contratação e fornecedores. O uso de ferramentas deste tipo ´e considerado um diferencial competitivo, levando estas a investirem maciçamente em pesquisa e desenvolvimento de forma a aumentar os lucros, influenciando desta forma seu modelo de estratégia e organização. A Logística é o processo de planear, implementar e controlar de forma eficiente o fluxo e o armazenamento de produtos, bem como os serviços de informação associados, cobrindo desde o ponto de origem até o ponto de consumo, sendo que o foco será sempre de atender os requisitos do consumidor. Este projeto aborda a integração da logística com a TI, uma vez que a informação é um elemento-chave da logística. Esta atividade visa analisar as aplicações da TI e sua influência no modelo de estratégia organizacional. A proposta de dissertação apresentada neste documento tem como objetivo principal o desenvolvimento de um sistema de monitorização contínua de produto acabado, também conhecido como logística externa. Dada a responsabilidade e a importância de um projeto destes, diferentes técnicas e metodologias são cuidadosamente abordadas, para garantir a confiabilidade e a organização correta das informações presentes no sistema, bem como uma projeção para expansão num futuro próximo. É proposto um ambiente inteligente de forma a rastrear e fornecer informação em tempo real dos produtos em transito. O principal foco ´e que o utilizador não deve ser forçado a procurar ativamente por desvios, mas ser capaz de realizar outras tarefas e ser avisado de qualquer alteração no processo de transporte. Foi concebido um protótipo no qual o comportamento e as interações externas do sistema foram exaustivamente testadas e validadas. O resultado do trabalho é um sistema capaz de acompanhar o produto acabado em trânsito, bem como fornecer relatórios adequados para os utilizadores, a fim de prever melhor ou avaliar com mais precisão eventuais desvios

    Tesis (DCI)--FCEFN-UNC, 2019En la presente tesis se presenta el desarrollo de papeles bioactivos con potencial aplicación en el envasado activo de alimentos. Para tal fin, se propuso el injerto de eugenol, un compuesto de origen natural con propiedades antimicrobiana, antioxidante y repelente de insectos, en celulosa, utilizando ácido policarboxílico como agente ligante. Con el objetivo de evaluar la escalabilidad del proceso propuesto, se estudiaron distintas tecnologías de curado, tales como calentamiento por convección, infrarrojo, microondas y conducción. En todos los casos, se analizaron la influencia de las variables operativas sobre el avance de la reacción y propiedades finales del papel preparado, utilizando un diseño de experimentos Doehlert para elegir las experiencias a realizar, y analizando los resultados mediante metodología de superficie de respuesta y análisis estadístico ANOVA. Se pudo comprobar que la reacción de injerto de eugenol en papel comercial se produjo con éxito en todas las tecnologías estudiadas. Asimismo, se encontraron las condiciones óptimas de reacción para cada una de las tecnologías, para lo cual se buscó un compromiso entre el avance de la reacción y las propiedades finales del material (mecánicas y color). A partir de estas condiciones, se prepararon papeles y se realizó una caracterización más específica para su aplicación como envase de alimentos comparando los papeles modificados con el papel virgen. Se analizaron las propiedades mecánicas por ensayo de tracción, rasgado y punzonado y se midió la absorción de agua y la capacidad de degradación. Por otro lado, las propiedades bioactivas analizadas fueron la actividad antioxidante, antimicrobiana, repelente e insecticida de gorgojos (T. castaneum y R. dominica). Una vez probado que el papel modificado presenta buenas características físicas y bioactivas para su posible aplicación en el envasado de alimentos, se realizaron prototipos de envasado para harina, como alimento representativo de alimentos derivados de cereales, susceptibles al ataque de plagas. En este estudio se analizó la migración de reactivos, propiedades organolépticas y conservación del alimento, arrojando resultados promisorios para la industria de envases de alimentos. Finalmente, se realizó una comparación de las tecnologías de curado ensayadas, analizando diferentes aspectos como avance de reacción, propiedades finales, apariencia, tiempo de reacción, consumo de energía, entre otros, como así también disponibilidad y uso de estas tecnologías a escala industrial, seleccionando la tecnología de conducción como la más adecuada para una propuesta de escalado industrial.Fil: Muratore, Florencia.

    Consent and the Construction of the Volunteer: Institutional Settings of Experimental Research on Human Beings in Britain during the Cold War

    This study challenges the primacy of consent in the history of human experimentation and argues that privileging the cultural frameworks adds nuance to our understanding of the construction of the volunteer in the period 1945 to 1970. Historians and bio-ethicists have argued that medical ethics codes have marked out the parameters of using people as subjects in medical scientific research and that the consent of the subjects was fundamental to their status as volunteers. However, the temporality of the creation of medical ethics codes means that they need to be understood within their historical context. That medical ethics codes arose from a specific historical context rather than a concerted and conscious determination to safeguard the well-being of subjects needs to be acknowledged. The British context of human experimentation is under-researched and there has been even less focus on the cultural frameworks within which experiments took place. This study demonstrates, through a close analysis of the Medical Research Council's Common Cold Research Unit (CCRU) and the government's military research facility, the Chemical Defence Experimental Establishment, Porton Down (Porton), that the `volunteer' in human experiments was a subjective entity whose identity was specific to the institution which recruited and made use of the subject. By examining representations of volunteers in the British press, the rhetoric of the government's collectivist agenda becomes evident and this fed into the institutional construction of the volunteer at the CCRU. In contrast, discussions between Porton scientists, staff members, and government officials demonstrate that the use of military personnel in secret chemical warfare experiments was far more complex. Conflicting interests of the military, the government and the scientific imperative affected how the military volunteer was perceived

    Augmented classification for electrical coil winding defects

    Get PDF
    A green revolution has accelerated over the recent decades with a look to replace existing transportation power solutions through the adoption of greener electrical alternatives. In parallel the digitisation of manufacturing has enabled progress in the tracking and traceability of processes and improvements in fault detection and classification. This paper explores electrical machine manufacture and the challenges faced in identifying failures modes during this life cycle through the demonstration of state-of-the-art machine vision methods for the classification of electrical coil winding defects. We demonstrate how recent generative adversarial networks can be used to augment training of these models to further improve their accuracy for this challenging task. Our approach utilises pre-processing and dimensionality reduction to boost performance of the model from a standard convolutional neural network (CNN) leading to a significant increase in accuracy

    Application of lactic acid bacteria for the biopreservation of meat products: A systematic review

    Get PDF
    .The increasing concern of consumers about food quality and safety and their rejection of chemical additives has promoted the breakthrough of the biopreservation field and the development of studies on the use of beneficial bacteria and their metabolites as potential natural antimicrobials for shelf life extension and enhanced food safety. Control of foodborne pathogens in meat and meat products represents a serious challenge for the food industry which can be addressed through the intelligent use of bio-compounds or biopreservatives. This article aims to systematically review the available knowledge about biological strategies based on the use of lactic acid bacteria to control the proliferation of undesirable microorganisms in different meat products. The outcome of the literature search evidenced the potential of several strains of lactic acid bacteria and their purified or semi-purified antimicrobial metabolites as biopreservatives in meat products for achieving longer shelf life or inhibiting spoilage and pathogenic bacteria, especially when combined with other technologies to achieve a synergistic effect.S

    The cultural center of the world : art, finance, and globalization in late twentieth-century New York

    Get PDF
    This article explores why New York City’s municipal government, together with private benefactors, poured an unprecedented amount of money into the arts during the 1980s, a time of broader austerity. While other public expenditures saw dramatic cuts, the arts were considered essential to the city’s future as a center for global capital—as a way to lure financial elites and young professionals to the city, create new forms of revenue-raising consumption, and cement New York’s reputation as the ultimate global city. New York had always had a vital arts scene. But in the 1980s, the arts were monetized in new ways to serve capital—and capitalists. Arts and culture were central to the new urban lifestyle that helped produce the explosion of global finance. But as arts and culture increasingly came to be associated with a luxury lifestyle, the arts themselves became a luxury, inaccessible to most New Yorkers
