    This paper deals with the medium between two reconfigurable sensor nodes characterized by radio interfaces that support multiple channels for exchanging real-time messages under energy constraints. These constraints are violated if the consumed energy in transmission is higher than the remaining quantity of energy. A reconfiguration, i.e., any addition or removal of tasks in devices and consequently of messages on the medium, can cause the violation of real-time or energy constraints at run time. To achieve a feasible scheduling in time (i.e., message deadlines will be respected) and energy (i.e., there is available energy) on the medium, we propose new dynamic solutions: Balance, Dilute, and a Combination of them to manage any addition or removal of messages. The proposed approach utilizes the energy harvesting techniques and the PowerControl algorithm to reduce the nonharvested consumed energy. The proposed strategies achieve significant improvement over existing methods and provide the highest percentage of adding messages, with a lower average in response time and energy consumption. They reach a percentage of success in adding the highest priority messages while meeting deadlines up to 85%.

    Authors: Müller, Franziska;

    Esta dissertação explora o modo como a empresa multinacional Unilever tem por objetivo a reconciliação da lógica Comercial e a de Sustentabilidade nas suas principais atividades de negócio, de modo a atingir o hibridismo organizacional. Baseando-se num estudo de caso, demonstra como a Unilever interliga estas duas lógicas através de três fatores distintos: liderança, comunicação e ações. O estudo qualitativo revela que o sucesso desta integração e a sustentação das mesmas não deriva de um único fator em específico, mas sim da interação planeada entre esses três fatores. De acordo com os resultados da minha análise, desenvolvi um modelo que demonstra como as duas lógicas mudam ao longo do tempo, influenciadas por dinâmicas tanto internas como externas. This dissertation explores how the multinational company Unilever aims at reconciling two logics, a Sustainability and a Commercial Logic within its core business activities to achieve organizational hybridity. Based on a case study, it shows that Unilever reconciles the two logics through three distinct drivers: leadership, communication and actions. The qualitative study reveals that there is not a specific single driver that can lead to a successful integration and sustaining of logics, but rather the planned interplay between the three drivers. Resulting from my findings, I developed a model that elucidates how the two logics change over time through both internal and external dynamics.

    Authors: Sousa, Pedro Duarte Leal Costa;

    No mundo atual em que vivemos, em constante mudança, o setor dos transportes tem um papel crucial na atividade económica mundial. Contudo, representa um consumo elevado de recursos energéticos e ainda é um dos principais responsáveis pela emissão de gases com efeito de estufa. A mobilidade elétrica e eletrificação das frotas contribuiu para uma redução direta da emissão de gases, representando uma vantagem sobre os veículos com motores de combustão interna. Todavia, a limitação dos sistemas de armazenamento de energia elétrica em termos de autonomia (número de quilómetros percorridos) ainda é um dos maiores entraves a uma maior penetração no mercado dos veículos elétricos. No setor mais específico dos autocarros elétricos, em particular o autocarro de aeroporto, esta desvantagem é amplificada não só pela dimensão e peso, mas também pelos sistemas auxiliares de aquecimento, ventilação e ar-condicionado (AVAC) inerentes a este tipo de veículos. O presente trabalho tem por objetivo a análise e otimização da eficiência energética do modelo e.Cobus, um autocarro de aeroporto. Para alcançar o objetivo foram estudadas algumas unidades e.Cobus em condições reais de operação e analisadas as potências e consumos de energia das diferentes cargas, criando diversos dataset’s. Com os dataset’s elaborados, e recorrendo à plataforma de aprendizagem máquina WEKA, e aplicação de alguns algoritmos, foram desenvolvidos modelos de previsão do consumo de energia que permitiram otimizar a capacidade de armazenamento energético (baterias) destes autocarros, em função da utilização e local geográfico

    Authors: Viegas, Ivan; Vieira, Susana M.; Sousa, João M. C.; Melício, R.; +1 Authors

    This work proposes a methodology for predicting the typical daily load profile of electricity usage based on static data obtained from surveys. The methodology intends to: (1) determine consumer segments based on the metering data using the k-means clustering algorithm, (2) correlate survey data to the segments, and (3) develop statistical and machine learning classification models to predict the demand profile of the consumers. The developed classification models contribute to make the study and planning of demand side management programs easier, provide means for studying the impact of alternative tariff setting methods and generate useful knowledge for policy makers.

    Recognizing the benefit that one can get by exploiting the Micro-Grid (MG) concept, as an active part of the Low Voltage (LV) network comprising several micro-generation (µG) sources, controllable loads and storage devices, is a key issue towards the MG concept deployment. Furthermore, the MG concept is extended into Multi-Micro Grid (MMG) concept, identifying the benefits that can be obtained at Medium Voltage (MV) level. The main idea behind this research is to show what one gains and what one looses by setting up the MG concept. Therefore, the benefits reported, are evaluated through a cost-benefit approach by modeling the problem as a multi-attribute problem using several Decision-Aid (DA) techniques to capture different Decision Maker (DM) preference structures.

    Authors: Grossowicz, Michal; Marques, Gonçalo M.; van Voorn, George A.K.;

    Small but numerically dominant species such as the cyanobacteria Prochlorococcus play a pivotal role in major nutrient cycles. To understand how Prochlorococcus populations affect nutrient flows, we present and analyze two alternative population models. These models − one including over-shading effects and one not − are based on Dynamic Energy Budget (DEB) theory to describe how growth may be affected by the availability of CO2 and/or inorganic nutrients and by changes in light conditions. In these models individuals have reserves for C, N, and P from which fluxes for maintenance and growth are mobilized. Time series data from laboratory studies of growth under three different nutrient concentrations are used to calibrate the models. The model with carbon, nitrogen and phosphate as limiting factors can reasonably describe the growth in the low N and low P media experiments, while the model with over-shading gives a proper description of the growth under all tested experimental conditions. Modeled C:N:P ratios are within range of reported in scientific literature ones and similar to measured ratios. The results suggest that (1) reserves play a critical role for cyanobacteria to thrive under the often oligotrophic conditions in which they live, and (2) over-shading has a considerable effect as co-limiting factor on the growth of cyanobacteria. We argue that an individual DEB-based model in which multiple nutrient limitations are presented can be used to successfully describe cyanobacterium growth patterns in batch cultures.

    Authors: Sá, Rita Alexandra Viana de;

    As alterações climáticas e a urgência na mudança de hábitos de consumo são questões que têm vindo a ser discutidas ao longo dos anos. Com o foco na importância de existir medidas sustentáveis para mitigar os impactos ambientais, surgiu a seguinte pergunta de pesquisa: “Podem ser feitos acessórios modulares com o reaproveitamento de têxteis e construídos apenas com o encaixe entre módulos?”. Para além disso, questiona-se a possibilidade de desenvolver um acessório, que permita ao consumidor a montagem/desmontagem consoante as suas necessidades e que tenha uma preocupação com o zero desperdício. Para alcançar os objetivos avançou-se com um processo de desenvolvimento de novos produtos que se dividiu em quatro fases. A primeira consistiu na caracterização dos substratos-base, destacando a resistência à formação de borboto e à flexão, assim como a repelência à água. A segunda concentrou-se na identificação de formas, estruturas, métodos e sistemas de encaixe mais adequados para o acessório, chegando-se à conclusão, por exemplo, que as formas curvas são as mais apropriadas, tendo em conta que não contenham estruturas vazadas. A terceira etapa envolveu uma seleção, considerando o desempenho de cada amostra a testes laboratoriais no aparelho do Dinamómetro. Por fim, a última etapa abarcou um estudo de soluções para melhorar o material em termos de rigidez e de repelência à água através de um acabamento de amido de milho. A investigação ocorreu durante 8 meses, recolhendo um conjunto diversificado de dados, tais como, esboços, experiências, desenhos digitais, notas, amostras, projetos experimentais, fotografias e protótipos que desempenharam um papel crucial no progresso do estudo. O resultado consiste numa bolsa de 100 módulos feita de resíduos de não-tecido 100% Lã Burel, concebido para a reciclagem e com zero desperdício. É um produto versátil, sustentável, resistente e a sua funcionalidade, adaptabilidade e personalização tornam atraente para uma variedade de aplicações, desde carteiras até cintos e pulseiras. Além disso, a reversibilidade do design amplia as opções de uso, enquanto a alça ajustável com 10 zonas de regulação contribui para a sua praticidade. Esta investigação ofereceu um novo produto com modificações incrementais e um redesenho, colaborando significativamente para o campo do design modular. Validou teorias através de investigações, ofereceu soluções sustentáveis e procurou promover a conscientização ambiental. Suas implicações são cruciais para a gestão de recursos e resíduos em um mundo que enfrenta desafios ambientais urgentes. Este trabalho apela à ação, incentivando a pesquisa contínua e a adoção de produtos sustentáveis. Climate change and the urgency to change consumption habits are issues that have been discussed over the years. Focusing on the importance of having sustainable measures to mitigate environmental impacts, the following research question arose: “Can modular accessories be made by reusing textiles and built simply by fitting modules together?” Furthermore, the possibility of developing an accessory is questioned, which allows the consumer to assemble/disassemble according to their needs and it is concerned with zero waste. To achieve the objectives, a product development process was carried out, which was divided into four phases. The first consisted of characterizing the base substrates, highlighting resistance to pilling and flexing, as well as water repellence. The second focused on identifying the most suitable shapes, structures, methods and fitting systems for the accessory, reaching the conclusion, for example, that curved shapes are the most appropriate, taking into account that they do not contain hollow structures. The third stage involved a selection, considering the performance of each sample in laboratory tests on the Dynamometer device. Finally, the last stage included a study of solutions to improve the material in terms of rigidity and water repellence through a cornstarch finish. The research took place over 8 months, collecting a diverse set of data such as sketches, experiments, digital drawings, notes, samples, experimental designs, photographs and prototypes that played a crucial role in the progress of the study. The result consists of a bag of 100 modules made from 100% Burel Wool non-woven waste, designed for recycling and with zero waste. It is a versatile, sustainable, resistant product and its functionality, adaptability and customization make it attractive for a variety of applications, from wallets to belts and bracelets. Furthermore, the reversibility of the design expands the usage options, while the adjustable strap with 10 adjustment zones contributes to its practicality. This research offered a new product with incremental modifications and a redesign, significantly contributing to the field of modular design. It validated theories through investigations, offered sustainable solutions and sought to promote environmental awareness. Its implications are crucial for resource and waste management in a world facing urgent environmental challenges. This work calls for action, encouraging continued research and adoption of sustainable products. Dissertação de mestrado em Design e Marketing de Produto Têxtil, Vestuário e Acessórios

    Authors: Sá, Rita Alexandra Viana de;

    As alterações climáticas e a urgência na mudança de hábitos de consumo são questões que têm vindo a ser discutidas ao longo dos anos. Com o foco na importância de existir medidas sustentáveis para mitigar os impactos ambientais, surgiu a seguinte pergunta de pesquisa: “Podem ser feitos acessórios modulares com o reaproveitamento de têxteis e construídos apenas com o encaixe entre módulos?”. Para além disso, questiona-se a possibilidade de desenvolver um acessório, que permita ao consumidor a montagem/desmontagem consoante as suas necessidades e que tenha uma preocupação com o zero desperdício. Para alcançar os objetivos avançou-se com um processo de desenvolvimento de novos produtos que se dividiu em quatro fases. A primeira consistiu na caracterização dos substratos-base, destacando a resistência à formação de borboto e à flexão, assim como a repelência à água. A segunda concentrou-se na identificação de formas, estruturas, métodos e sistemas de encaixe mais adequados para o acessório, chegando-se à conclusão, por exemplo, que as formas curvas são as mais apropriadas, tendo em conta que não contenham estruturas vazadas. A terceira etapa envolveu uma seleção, considerando o desempenho de cada amostra a testes laboratoriais no aparelho do Dinamómetro. Por fim, a última etapa abarcou um estudo de soluções para melhorar o material em termos de rigidez e de repelência à água através de um acabamento de amido de milho. A investigação ocorreu durante 8 meses, recolhendo um conjunto diversificado de dados, tais como, esboços, experiências, desenhos digitais, notas, amostras, projetos experimentais, fotografias e protótipos que desempenharam um papel crucial no progresso do estudo. O resultado consiste numa bolsa de 100 módulos feita de resíduos de não-tecido 100% Lã Burel, concebido para a reciclagem e com zero desperdício. É um produto versátil, sustentável, resistente e a sua funcionalidade, adaptabilidade e personalização tornam atraente para uma variedade de aplicações, desde carteiras até cintos e pulseiras. Além disso, a reversibilidade do design amplia as opções de uso, enquanto a alça ajustável com 10 zonas de regulação contribui para a sua praticidade. Esta investigação ofereceu um novo produto com modificações incrementais e um redesenho, colaborando significativamente para o campo do design modular. Validou teorias através de investigações, ofereceu soluções sustentáveis e procurou promover a conscientização ambiental. Suas implicações são cruciais para a gestão de recursos e resíduos em um mundo que enfrenta desafios ambientais urgentes.

    Authors: Veiga, Bruno Miguel Salgueiro;

    Este relatório é o produto de um estágio curricular, realizado na Domingos da Silva Teixeira, DST, que teve por objetivo calcular a pegada de carbono da empresa e propor melhorias nas estratégias de redução das emissões de gases com efeito de estufa. As externalidades negativas relacionadas com a queima de combustíveis fósseis provocaram, desde a revolução industrial, o problema das alterações climáticas. Neste contexto, as empresas começam a integrar preocupações ambientais nas suas estratégias de negócio, por forma a serem mais eficientes. Uma ação de grande importância é o cálculo da pegada de carbono, que contabiliza toda a responsabilidade climática da organização. Neste trabalho, após o estabelecimento de uma parceria entre Universidade do Minho e a Research Feel, utilizou-se o Método Composto das Contas Financeiras (MC3) de Juan Luis Doménech, para cálculo da pegada de carbono, compatível com outras metodologias como a ISO 14069. Os resultados obtidos são divididos em emissões diretas do uso de combustíveis fósseis, que correspondem a cerca de 13% da pegada, ou 13 251 tCO2eq.; emissões indiretas provenientes do uso de energia, que respeitam a cerca de 4%, ou 4 456 tCO2eq.; e, por fim, outras emissões indiretas, sendo a grande fatia de 83% representativa da responsabilidade climática da DST, isto é, 88 110 tCO2eq. O terceiro âmbito pode, por vezes, ser encarado como responsabilidade climática dos utilizadores finais dos produtos. No entanto, optou-se pela referência completa dos resultados dado o enquadramento académico deste relatório e, também, porque reflete uma oportunidade para a DST lutar contra as alterações climáticas. A “hereditariedade” da pegada de produtos usados em projetos e serviços de fabricação ou construção da DST pode ser minimizada através do chamado efeito dominó em que a responsabilidade é deslocada para o verdadeiro causador, isto é, a cadeia de abastecimento da DST. Uma política de compras “verdes” é a principal medida que se conclui adotar de forma a reduzir a pegada de carbono da empresa. Outras melhorias indicadas, muitas já em implementação e de menor impacto, incluem a modificação do manual de boas práticas para os colaboradores da DST, uma maior aposta na utilização de energias renováveis e a eventual modificação do parque automóvel. Estas deverão ser aplicadas de forma gradual, promovendo o uso eficiente de todos os recursos, trazendo benefícios significativos a médio prazo, tornando a empresa mais sustentável. This report is the product of a curricular internship, held at Domingos da Silva Teixeira, DST, which aimed to assess the company's carbon footprint and propose strategic improvements to reduce greenhouse gas emissions. The negative externalities related to the burning of fossil fuels have, since the industrial revolution, caused the problem of climate change. In this context, companies are beginning to integrate environmental concerns into their business strategies in order to become more efficient. One important action is the calculation of the carbon footprint, which accounts for all the climatic responsibility of the organization. In this work, after the establishment of a partnership between University of Minho and Research Feel, Juan Luis Doménech's Compound Method of Financial Accounts (MC3) was used to calculate the carbon footprint, compatible with other methodologies such as ISO 14069. The results obtained are divided into direct emissions from the use of fossil fuels, corresponding to about 13% of the footprint, or 13,251 tCO2eq; indirect emissions from energy use, which account for approximately 4%, or 4,456 tCO2eq; and finally, to other indirect emissions, with the large share of 83% of the climatic responsibility belonging to DST, that is, 88 110 tCO2eq. The third scope can sometimes be seen as the climatic liability of the final users of the products. However, the full reference of the results was chosen given the academic framework of this report and because it reflects an opportunity for DST to fight against climate change. The "inheritance" of the footprint of products used in DST manufacturing or construction projects and services can be minimized through the so-called domino effect in which responsibility is shifted to the true causer, i.e. the DST supply chain. A "green" purchasing policy is thus the main measure that has been found to reduce the company's carbon footprint. Other improvements, many already under implementation and of lesser impact, include the modification of the best practices’ manual for DST employees, a greater focus on the use of renewable energies, and possible alteration of the fleet. These should be applied gradually, promoting the efficient use of all resources, bringing significant benefits in the mid-term, and making the company more sustainable.

    A control technique of multilevel converter topologies based on Direct Lyapunov Control method is presented in this paper for integration of Distributed Generation (DG) resources into the power grid. The compensation of instantaneous variations in the reference current components in ac-side and dc-voltage variations of cascaded capacitors in dc-side of the interfacing system are considered properly, which is the main contribution and novelty of this work in comparison with other control strategies. The proposed control technique provides the continuous injection of active power in fundamental frequency from DG sources to the grid. In addition, reactive power and harmonic current components of loads are provided with a fast dynamic response; thereby, achieving sinusoidal grid currents in phase with load voltages, while the required power from load side is more than the maximum capacity of interfaced converter, is possible. Simulation results confirm the effectiveness of the proposed control strategy in DG technology during dynamic and steady-state operating conditions.

In addition, reactive power and harmonic current components of loads are provided with a fast dynamic response; thereby, achieving sinusoidal grid currents in phase with load voltages, while the required power from load side is more than the maximum capacity of interfaced converter, is possible. Simulation results confirm the effectiveness of the proposed control strategy in DG technology during dynamic and steady-state operating conditions.

    This paper deals with the medium between two reconfigurable sensor nodes characterized by radio interfaces that support multiple channels for exchanging real-time messages under energy constraints. These constraints are violated if the consumed energy in transmission is higher than the remaining quantity of energy. A reconfiguration, i.e., any addition or removal of tasks in devices and consequently of messages on the medium, can cause the violation of real-time or energy constraints at run time. To achieve a feasible scheduling in time (i.e., message deadlines will be respected) and energy (i.e., there is available energy) on the medium, we propose new dynamic solutions: Balance, Dilute, and a Combination of them to manage any addition or removal of messages. The proposed approach utilizes the energy harvesting techniques and the PowerControl algorithm to reduce the nonharvested consumed energy. The proposed strategies achieve significant improvement over existing methods and provide the highest percentage of adding messages, with a lower average in response time and energy consumption. They reach a percentage of success in adding the highest priority messages while meeting deadlines up to 85%.

    Authors: Müller, Franziska;

    Esta dissertação explora o modo como a empresa multinacional Unilever tem por objetivo a reconciliação da lógica Comercial e a de Sustentabilidade nas suas principais atividades de negócio, de modo a atingir o hibridismo organizacional. Baseando-se num estudo de caso, demonstra como a Unilever interliga estas duas lógicas através de três fatores distintos: liderança, comunicação e ações. O estudo qualitativo revela que o sucesso desta integração e a sustentação das mesmas não deriva de um único fator em específico, mas sim da interação planeada entre esses três fatores. De acordo com os resultados da minha análise, desenvolvi um modelo que demonstra como as duas lógicas mudam ao longo do tempo, influenciadas por dinâmicas tanto internas como externas. This dissertation explores how the multinational company Unilever aims at reconciling two logics, a Sustainability and a Commercial Logic within its core business activities to achieve organizational hybridity. Based on a case study, it shows that Unilever reconciles the two logics through three distinct drivers: leadership, communication and actions. The qualitative study reveals that there is not a specific single driver that can lead to a successful integration and sustaining of logics, but rather the planned interplay between the three drivers.

    Authors: Sousa, Pedro Duarte Leal Costa;

    No mundo atual em que vivemos, em constante mudança, o setor dos transportes tem um papel crucial na atividade económica mundial. Contudo, representa um consumo elevado de recursos energéticos e ainda é um dos principais responsáveis pela emissão de gases com efeito de estufa. A mobilidade elétrica e eletrificação das frotas contribuiu para uma redução direta da emissão de gases, representando uma vantagem sobre os veículos com motores de combustão interna. Todavia, a limitação dos sistemas de armazenamento de energia elétrica em termos de autonomia (número de quilómetros percorridos) ainda é um dos maiores entraves a uma maior penetração no mercado dos veículos elétricos. No setor mais específico dos autocarros elétricos, em particular o autocarro de aeroporto, esta desvantagem é amplificada não só pela dimensão e peso, mas também pelos sistemas auxiliares de aquecimento, ventilação e ar-condicionado (AVAC) inerentes a este tipo de veículos. O presente trabalho tem por objetivo a análise e otimização da eficiência energética do modelo e.Cobus, um autocarro de aeroporto. Para alcançar o objetivo foram estudadas algumas unidades e.Cobus em condições reais de operação e analisadas as potências e consumos de energia das diferentes cargas, criando diversos dataset’s. Com os dataset’s elaborados, e recorrendo à plataforma de aprendizagem máquina WEKA, e aplicação de alguns algoritmos, foram desenvolvidos modelos de previsão do consumo de energia que permitiram otimizar a capacidade de armazenamento energético (baterias) destes autocarros, em função da utilização e local geográfico

    Authors: Sousa, Pedro Duarte Leal Costa;

    No mundo atual em que vivemos, em constante mudança, o setor dos transportes tem um papel crucial na atividade económica mundial. Contudo, representa um consumo elevado de recursos energéticos e ainda é um dos principais responsáveis pela emissão de gases com efeito de estufa. A mobilidade elétrica e eletrificação das frotas contribuiu para uma redução direta da emissão de gases, representando uma vantagem sobre os veículos com motores de combustão interna. Todavia, a limitação dos sistemas de armazenamento de energia elétrica em termos de autonomia (número de quilómetros percorridos) ainda é um dos maiores entraves a uma maior penetração no mercado dos veículos elétricos. No setor mais específico dos autocarros elétricos, em particular o autocarro de aeroporto, esta desvantagem é amplificada não só pela dimensão e peso, mas também pelos sistemas auxiliares de aquecimento, ventilação e ar-condicionado (AVAC) inerentes a este tipo de veículos. O presente trabalho tem por objetivo a análise e otimização da eficiência energética do modelo e.Cobus, um autocarro de aeroporto. Para alcançar o objetivo foram estudadas algumas unidades e.Cobus em condições reais de operação e analisadas as potências e consumos de energia das diferentes cargas, criando diversos dataset’s. Com os dataset’s elaborados, e recorrendo à plataforma de aprendizagem máquina WEKA, e aplicação de alguns algoritmos, foram desenvolvidos modelos de previsão do consumo de energia que permitiram otimizar a capacidade de armazenamento energético (baterias) destes autocarros, em função da utilização e local geográfico

    This work proposes a methodology for predicting the typical daily load profile of electricity usage based on static data obtained from surveys. The methodology intends to: (1) determine consumer segments based on the metering data using the k-means clustering algorithm, (2) correlate survey data to the segments, and (3) develop statistical and machine learning classification models to predict the demand profile of the consumers. The developed classification models contribute to make the study and planning of demand side management programs easier, provide means for studying the impact of alternative tariff setting methods and generate useful knowledge for policy makers.

    Recognizing the benefit that one can get by exploiting the Micro-Grid (MG) concept, as an active part of the Low Voltage (LV) network comprising several micro-generation (µG) sources, controllable loads and storage devices, is a key issue towards the MG concept deployment. Furthermore, the MG concept is extended into Multi-Micro Grid (MMG) concept, identifying the benefits that can be obtained at Medium Voltage (MV) level. The main idea behind this research is to show what one gains and what one looses by setting up the MG concept. Therefore, the benefits reported, are evaluated through a cost-benefit approach by modeling the problem as a multi-attribute problem using several Decision-Aid (DA) techniques to capture different Decision Maker (DM) preference structures.

    Authors: Grossowicz, Michal; Marques, Gonçalo M.; van Voorn, George A.K.;

    Small but numerically dominant species such as the cyanobacteria Prochlorococcus play a pivotal role in major nutrient cycles. To understand how Prochlorococcus populations affect nutrient flows, we present and analyze two alternative population models. These models − one including over-shading effects and one not − are based on Dynamic Energy Budget (DEB) theory to describe how growth may be affected by the availability of CO2 and/or inorganic nutrients and by changes in light conditions. In these models individuals have reserves for C, N, and P from which fluxes for maintenance and growth are mobilized. Time series data from laboratory studies of growth under three different nutrient concentrations are used to calibrate the models. The model with carbon, nitrogen and phosphate as limiting factors can reasonably describe the growth in the low N and low P media experiments, while the model with over-shading gives a proper description of the growth under all tested experimental conditions. Modeled C:N:P ratios are within range of reported in scientific literature ones and similar to measured ratios. The results suggest that (1) reserves play a critical role for cyanobacteria to thrive under the often oligotrophic conditions in which they live, and (2) over-shading has a considerable effect as co-limiting factor on the growth of cyanobacteria. We argue that an individual DEB-based model in which multiple nutrient limitations are presented can be used to successfully describe cyanobacterium growth patterns in batch cultures.

    As alterações climáticas e a urgência na mudança de hábitos de consumo são questões que têm vindo a ser discutidas ao longo dos anos. Com o foco na importância de existir medidas sustentáveis para mitigar os impactos ambientais, surgiu a seguinte pergunta de pesquisa: “Podem ser feitos acessórios modulares com o reaproveitamento de têxteis e construídos apenas com o encaixe entre módulos?”. Para além disso, questiona-se a possibilidade de desenvolver um acessório, que permita ao consumidor a montagem/desmontagem consoante as suas necessidades e que tenha uma preocupação com o zero desperdício. Para alcançar os objetivos avançou-se com um processo de desenvolvimento de novos produtos que se dividiu em quatro fases. A primeira consistiu na caracterização dos substratos-base, destacando a resistência à formação de borboto e à flexão, assim como a repelência à água. A segunda concentrou-se na identificação de formas, estruturas, métodos e sistemas de encaixe mais adequados para o acessório, chegando-se à conclusão, por exemplo, que as formas curvas são as mais apropriadas, tendo em conta que não contenham estruturas vazadas. A terceira etapa envolveu uma seleção, considerando o desempenho de cada amostra a testes laboratoriais no aparelho do Dinamómetro. Por fim, a última etapa abarcou um estudo de soluções para melhorar o material em termos de rigidez e de repelência à água através de um acabamento de amido de milho. A investigação ocorreu durante 8 meses, recolhendo um conjunto diversificado de dados, tais como, esboços, experiências, desenhos digitais, notas, amostras, projetos experimentais, fotografias e protótipos que desempenharam um papel crucial no progresso do estudo. O resultado consiste numa bolsa de 100 módulos feita de resíduos de não-tecido 100% Lã Burel, concebido para a reciclagem e com zero desperdício. É um produto versátil, sustentável, resistente e a sua funcionalidade, adaptabilidade e personalização tornam atraente para uma variedade de aplicações, desde carteiras até cintos e pulseiras. Além disso, a reversibilidade do design amplia as opções de uso, enquanto a alça ajustável com 10 zonas de regulação contribui para a sua praticidade. Esta investigação ofereceu um novo produto com modificações incrementais e um redesenho, colaborando significativamente para o campo do design modular. Validou teorias através de investigações, ofereceu soluções sustentáveis e procurou promover a conscientização ambiental. Suas implicações são cruciais para a gestão de recursos e resíduos em um mundo que enfrenta desafios ambientais urgentes. Este trabalho apela à ação, incentivando a pesquisa contínua e a adoção de produtos sustentáveis. Climate change and the urgency to change consumption habits are issues that have been discussed over the years. Focusing on the importance of having sustainable measures to mitigate environmental impacts, the following research question arose: “Can modular accessories be made by reusing textiles and built simply by fitting modules together?” Furthermore, the possibility of developing an accessory is questioned, which allows the consumer to assemble/disassemble according to their needs and it is concerned with zero waste. To achieve the objectives, a product development process was carried out, which was divided into four phases. The first consisted of characterizing the base substrates, highlighting resistance to pilling and flexing, as well as water repellence. The second focused on identifying the most suitable shapes, structures, methods and fitting systems for the accessory, reaching the conclusion, for example, that curved shapes are the most appropriate, taking into account that they do not contain hollow structures. The third stage involved a selection, considering the performance of each sample in laboratory tests on the Dynamometer device. Finally, the last stage included a study of solutions to improve the material in terms of rigidity and water repellence through a cornstarch finish. The research took place over 8 months, collecting a diverse set of data such as sketches, experiments, digital drawings, notes, samples, experimental designs, photographs and prototypes that played a crucial role in the progress of the study. The result consists of a bag of 100 modules made from 100% Burel Wool non-woven waste, designed for recycling and with zero waste. It is a versatile, sustainable, resistant product and its functionality, adaptability and customization make it attractive for a variety of applications, from wallets to belts and bracelets. Furthermore, the reversibility of the design expands the usage options, while the adjustable strap with 10 adjustment zones contributes to its practicality. This research offered a new product with incremental modifications and a redesign, significantly contributing to the field of modular design. It validated theories through investigations, offered sustainable solutions and sought to promote environmental awareness. Its implications are crucial for resource and waste management in a world facing urgent environmental challenges. This work calls for action, encouraging continued research and adoption of sustainable products. Dissertação de mestrado em Design e Marketing de Produto Têxtil, Vestuário e Acessórios

    Este relatório é o produto de um estágio curricular, realizado na Domingos da Silva Teixeira, DST, que teve por objetivo calcular a pegada de carbono da empresa e propor melhorias nas estratégias de redução das emissões de gases com efeito de estufa. As externalidades negativas relacionadas com a queima de combustíveis fósseis provocaram, desde a revolução industrial, o problema das alterações climáticas. Neste contexto, as empresas começam a integrar preocupações ambientais nas suas estratégias de negócio, por forma a serem mais eficientes. Uma ação de grande importância é o cálculo da pegada de carbono, que contabiliza toda a responsabilidade climática da organização. Neste trabalho, após o estabelecimento de uma parceria entre Universidade do Minho e a Research Feel, utilizou-se o Método Composto das Contas Financeiras (MC3) de Juan Luis Doménech, para cálculo da pegada de carbono, compatível com outras metodologias como a ISO 14069. Os resultados obtidos são divididos em emissões diretas do uso de combustíveis fósseis, que correspondem a cerca de 13% da pegada, ou 13 251 tCO2eq.; emissões indiretas provenientes do uso de energia, que respeitam a cerca de 4%, ou 4 456 tCO2eq.; e, por fim, outras emissões indiretas, sendo a grande fatia de 83% representativa da responsabilidade climática da DST, isto é, 88 110 tCO2eq. O terceiro âmbito pode, por vezes, ser encarado como responsabilidade climática dos utilizadores finais dos produtos. No entanto, optou-se pela referência completa dos resultados dado o enquadramento académico deste relatório e, também, porque reflete uma oportunidade para a DST lutar contra as alterações climáticas. A “hereditariedade” da pegada de produtos usados em projetos e serviços de fabricação ou construção da DST pode ser minimizada através do chamado efeito dominó em que a responsabilidade é deslocada para o verdadeiro causador, isto é, a cadeia de abastecimento da DST. Uma política de compras “verdes” é a principal medida que se conclui adotar de forma a reduzir a pegada de carbono da empresa. Outras melhorias indicadas, muitas já em implementação e de menor impacto, incluem a modificação do manual de boas práticas para os colaboradores da DST, uma maior aposta na utilização de energias renováveis e a eventual modificação do parque automóvel. Estas deverão ser aplicadas de forma gradual, promovendo o uso eficiente de todos os recursos, trazendo benefícios significativos a médio prazo, tornando a empresa mais sustentável. This report is the product of a curricular internship, held at Domingos da Silva Teixeira, DST, which aimed to assess the company's carbon footprint and propose strategic improvements to reduce greenhouse gas emissions. The negative externalities related to the burning of fossil fuels have, since the industrial revolution, caused the problem of climate change. In this context, companies are beginning to integrate environmental concerns into their business strategies in order to become more efficient. One important action is the calculation of the carbon footprint, which accounts for all the climatic responsibility of the organization. In this work, after the establishment of a partnership between University of Minho and Research Feel, Juan Luis Doménech's Compound Method of Financial Accounts (MC3) was used to calculate the carbon footprint, compatible with other methodologies such as ISO 14069. The results obtained are divided into direct emissions from the use of fossil fuels, corresponding to about 13% of the footprint, or 13,251 tCO2eq; indirect emissions from energy use, which account for approximately 4%, or 4,456 tCO2eq; and finally, to other indirect emissions, with the large share of 83% of the climatic responsibility belonging to DST, that is, 88 110 tCO2eq. The third scope can sometimes be seen as the climatic liability of the final users of the products. However, the full reference of the results was chosen given the academic framework of this report and because it reflects an opportunity for DST to fight against climate change. The "inheritance" of the footprint of products used in DST manufacturing or construction projects and services can be minimized through the so-called domino effect in which responsibility is shifted to the true causer, i.e. the DST supply chain. A "green" purchasing policy is thus the main measure that has been found to reduce the company's carbon footprint. Other improvements, many already under implementation and of lesser impact, include the modification of the best practices’ manual for DST employees, a greater focus on the use of renewable energies, and possible alteration of the fleet. These should be applied gradually, promoting the efficient use of all resources, bringing significant benefits in the mid-term, and making the company more sustainable.

    Authors: Pouresmaeil, Edris; Mehrasa, Majid; P. S. Catalao, Joao;

    A control technique of multilevel converter topologies based on Direct Lyapunov Control method is presented in this paper for integration of Distributed Generation (DG) resources into the power grid. The compensation of instantaneous variations in the reference current components in ac-side and dc-voltage variations of cascaded capacitors in dc-side of the interfacing system are considered properly, which is the main contribution and novelty of this work in comparison with other control strategies. The proposed control technique provides the continuous injection of active power in fundamental frequency from DG sources to the grid. In addition, reactive power and harmonic current components of loads are provided with a fast dynamic response; thereby, achieving sinusoidal grid currents in phase with load voltages, while the required power from load side is more than the maximum capacity of interfaced converter, is possible. Simulation results confirm the effectiveness of the proposed control strategy in DG technology during dynamic and steady-state operating conditions.

    A control technique of multilevel converter topologies based on Direct Lyapunov Control method is presented in this paper for integration of Distributed Generation (DG) resources into the power grid. The compensation of instantaneous variations in the reference current components in ac-side and dc-voltage variations of cascaded capacitors in dc-side of the interfacing system are considered properly, which is the main contribution and novelty of this work in comparison with other control strategies. The proposed control technique provides the continuous injection of active power in fundamental frequency from DG sources to the grid. In addition, reactive power and harmonic current components of loads are provided with a fast dynamic response; thereby, achieving sinusoidal grid currents in phase with load voltages, while the required power from load side is more than the maximum capacity of interfaced converter, is possible. Simulation results confirm the effectiveness of the proposed control strategy in DG technology during dynamic and steady-state operating conditions.
