Esta dissertação trata do apoio ergonomico durante atividades de conversa e leitura em bancos públicos quando o corpo assume variadas posturas. São estruturados parâmetros de projeto associados a dimensionamentos antropométricos relacionados a posturas observadas. Os parâmetros são incorporados à estratégia procedural para geração de formas utilizando modelo geométrico com regras de combinação. O procedimento é testado no software Rhinoceros (Grasshopper) gerando designs alternativos de bancos que, associados a parâmetros de desempenho ergonômico, são funcionalmente analisados. O sistema paramétrico formulado com as informações das posturas assumidas permitiu a estruturação de uma metodologia de projeto que otimiza as informações trazidas pelas observações de uso do objeto traduzindo-as simultaneamente, de forma automática, para o design do produto e para o processo de fabricação. / This dissertation is about ergonomic body support during activities of reading and conversation realized on public benches, when a variety of postures are assumed by users. Design parameters are structured associated to antropometric dimensions related to observed ergonomic postures. These parameters are incorpored to a procedural strategy for shape generation using a geometric model with combination rules. The procedure is tested in the software Rhinoceros (Grasshopper) allowing the generation of design options for benches that, associated to fitness ergonomic parameters, are functionally analyzed. The parametric system formulated with the information of postures adopted, enabled the construction of a design methodology that optimizes informations brought from observation of the object, relating it both, to the product design and fabrication process.

Afin d’améliorer la qualité des solutions proposées par l’optimisation dans les processus de conception, il est important de se donner des outils permettant à l’optimiseur de parcourir l’espace de conception le plus largement possible. L’objet de cette Thèse est d’analyser différentes méthodes de paramétrage de formes surfaciques d’une automobile en vue de proposer à Renault un processus d’optimisation efficace. Trois méthodes sont analysées dans cette Thèse. Les deux premières sont issues de l’existant, et proposent de mélanger des formes, afin de créer de la diversité. Ainsi, on maximise l’exploration de l’espace de conception, tout en limitant l’effort de paramétrage des CAO. On montre qu’elles ont un fort potentiel, mais impliquent l’utilisation de méthodes d’optimisation difficiles à mettre en œuvre aujourd’hui. La troisième méthode étudiée consiste à exploiter la formulation de Koiter des équations de coques, qui intègre paramètres de forme et mécanique, et de l’utiliser pour faire de l’optimisation de forme sur critères mécaniques. Cette méthode a par ailleurs pour avantage de permettre le calcul des gradients. D’autre part, nous montrons qu’il est possible d’utiliser les points de contrôles de carreaux de Bézier comme paramètres d’optimisation, et ainsi, de limiter au strict nécessaire le nombre de variables du problème d’optimisation, tout en permettant une large exploration de l’espace de conception. Cependant, cette méthode est non-standard dans l’industrie et implique des développements spécifiques, qui ont été réalisés dans le cadre de cette Thèse. Enfin, nous mettons en place dans cette Thèse les éléments d’un processus d’optimisation de forme surfacique. / To improve optimized solutions quality in the design process, it is important to provide the optimizer tools to navigate the design space as much as possible. The purpose of this thesis is to analyze different parametrization methods for automotive surface shapes, in order to offer Renault an efficient optimization process. Three methods are analyzed in this thesis. The first two are closed to the existing ones, and propose to blend shapes to create diversity. Thus, we are able to maximize the exploration of the design space, while minimizing the effort for CAD setting. We show their high potential, but they involve the use of optimization methods difficult to implement today. The third method is designed to exploit the formulation of Koiter shell equations, which integrates mechanical and shape parameters, and to use it to perform shape optimization with respect to different mechanical criteria. This method also has the advantage of allowing the gradients calculation. On the other hand, we show that it is possible to use the Bezier’s control points as optimization parameters, and thus control the minimum number of variables necessary for the optimization problem, while allowing a broad exploration of the design space. However, this method is non-standard in the industry and involves specific developments that have been made in the context of this thesis. Finally, we implement in this thesis essentials elements of an optimization process for surface shapes.

The building sector consumes 32% of global energy used, and it is responsible for 20% of total greenhouse gases emissions. In Europe, more than one third of the buildings are 50 years or older, thus, it is critical that new dwellings are designed in the most efficient way from an energy perspective, since the consequences of the decisions taken today will remain during decades. The use of Building Information Modeling (BIM) software is promising for the design of a wide range of constructions; from small dwellings to big apartment buildings. These programs allow the architect, designer or civil consultant to perform several simulations of the energy behavior of a building in a timely manner, even before a single brick is put in place. Among them, IDA ICE software utilized in this thesis is a top rated program, situated by some authors within the four main building energy simulation tools. This is an outstanding fact considering that it is estimated in more than 400 the number of available BIM programs. With the help of IDA ICE it will be demonstrated that for a dwelling object of study, located in Madrid (Spain), it is possible to save up to 4 250€ through the entire life of the building if the proper orientation is chosen. The discussed literature and results will also show that orientation is, by far, the most critical passive design parameter related to a building, from which the efficacy of other related measures depends on.   It will be also proven that the optimal orientation depends on the weather where the dwelling is located, even though a general trend consisting in orienting the houses located in the northern hemisphere to the south, and vice versa, is observed. Building orientation, BIM programs, building energy consumption, passive design parameters, IDA-ICE simulation tool.

The ambition of the Swedish government is rapidly concentrating on the development of the renewable energy systems especially on wind energy, bio energy and solar energy. It has been observed on the growth of the production of electricity and heat from these three mentioned renewable energy systems. But, relatively in Sweden the share of production of electricity obtained from PV is quite smaller than the other two. The PV electricity production in Sweden comprises in a large scale of mainly the grid connected distributed PV systems and with a small number of installed solar parks. The aim of this paper is to analyze the viability of installing mid -size PV solar parks in Sweden and to simulate the effect of the proposed project in the village’s (Åled is the village where the proposed site is located) and the country’s electricity production. This study includes designing, simulation and financial analysis of different grid connected centralized mid -size capacities of PV solar parks of 250 kWp,500 kWp,1MWp and 2MWp. They are all fixed ground mounted systems. Moreover, it also discusses the main reasons that hinders decision makers, the PV complications that are connected to the grid, Sweden’s energy regulations particularly the emission regulation and the financial policies of PV. Also, study visit, telephone and email contacts have supplemented it. This study was done with the collaboration of Nyedal Solenergi, in which the proposed site was owned by the company and this paper will be a future guide for the investment of the mid-size PV solar park. According to the study a discussion has been made with the grid supplier (EON) in that area on the investment on one of the designed projects which are presented in this paper. The results of the study show that the effect of the proposed systems on the production of electricity in the village of Åled was between 2.68 – 21.4 % and the impact on the country’s PV electricity production was 0.2 – 1.58 %. And, the possibility of installing mid-size PV solar parks generally in Sweden particularly in the proposed site is possible and economically it is viable but not profitable for system capacities less than 1 MW. As the IRR found for all capacities is greater than the estimated WACC, hence each proposed capacity has the possibility of paying back all its investment costs in about 23 years. So, the profitability is very low in case of the 250 kWp and 500 kWp but for the others they have about 7-8 years of profitability. A sensitivity analysis also has shown the impact of initial investment costs, O & M costs and electricity export rate on the IRR, NPV and equity payback. The initial investment cost and electricity export rate were seen with high effect on the IRR, NPV and equity payback. The LCOE calculated was higher than the average electricity spot price (300 SEK/MWh) for 250 kWp and 500 kWp but lower for the other two capacities. The overall impact for the financial analysis was due to the decreasing of module prices, the rules that changes every year on electricity subsidies for renewables, tax reductions and rapid decreasing of electricity spot prices. In the future if the price of modules continues decreasing, spot price increases, more modification of the subsidy and introduction of new PV technologies integrated with other sources of energy is done then such projects could be more profitable.

Bakgrund En framgångsrik lansering av nya produkter är en viktig faktor för ett företags långsiktiga framgång och inom den marknadsföring som används idag så har grafisk design blivit alltmer obligatorisk som kommunikationsform. Företag försöker optimera sin marknadsföring på sociala medier då de blivit en brännpunkt för att informera och forma konsumenters beteende. Healthy homes arbetar med energieffektiva inneklimatlösningar och håller just nu på att lansera en inneklimat-mätare vid namn Sense. Problematiken ligger i att produkten inte har någon tidigare marknadsföring. Syfte Att ge en heltäckande bild av hur en viss typ av varumärke kan kommuniceras mot en tänkt målgrupp med hjälp av olika designparametrar och designparametrarnas betydelse i denna kommunikation. Även till att se vilka andra variabler som kan spela in och hur en lämplig process för att arbeta fram sådan design kan se ut. Metod Metoden utfördes i flera steg där en intervju med ansvarig från företaget initialt genomfördes för att grunda säljargument för kampanjernas utformning. Kampanjerna testades på representanter från företaget för att sedan publiceras på Facebook och Instagram. Därefter analyserades kampanjernas interaktioner. Resultat Intervjun gav en god grund för att formge kampanjerna. Analysen vi-sade att det inte fanns någon nämnvärd skillnad mellan kampanjerna sett till interaktioner, geografi och demografi. Dock lockades till största delen en äldre, manlig målgrupp och Facebook var den medieplattform överlägset gav flest länkklick. Slutsatser Det semistrukturerad intervjuformatet kan passa för att skapa öppen dialog och generera idéer om utformningar. Om det ej finns ett etablerat formspråk så kan det ge större friheter i formgivningen av annonser dock kan känslomässig annonsering kan utgöra en risk via Facebook Ads på grund av deras annonseringsregler. Följder Som yrkesutövare ger studien en bild av att kreativ frihet kan prioriteras högt vid marknadsföring av en ny produkt och/eller varumärke och att en djup förståelse för annonseringsregler på vald plattform kan spara både tid och pengar i marknadsföringsarbete. / Background A successful product launch is an important factor for a business’ longstanding success. Within marketing today graphic design has become an obligatory form of communication. Businesses try to optimize their social media marketing since it has become a centrepiece to inform consumers and form their behaviour. Healthy homes work with energy effective indoor climate solutions and are currently launching the indoor climate meter Sense. The problem lies in that the product currently does not have any previous marketing. Aim To give a comprehensive depiction of how a certain type of brand can be communicated to an imagined target group with the help of different design parameters and the importance of the design parameters in this communication. Also to see what other variables can influence and how a suitable process for producing that certain design can look like. Method Initially an interview with representatives from the company was implemented to base the sales arguments for the campaign designs. The campaigns were designed and tested on representatives from the company to later be published on Facebook and Instagram. Thereafter the campaign's interactions were analysed. Results The interview gave a good basis to campaign design. The analysis showed that there was no significant difference between the cam-paigns’ interactions, geography and demographics but that Facebook was the social media that gave most link clicks and mainly attracted an older demographic. Conclusions The semi-structured interview format can be suitable for creating an open dialogue and generating design ideas. If the design language is unestablished it can give more creative freedom in advertising design but emotional advertising can pose a risk on Facebook Ads due to their marketing rules. Implications As a graphic designer the study gives shows that creative freedom can be prioritized in marketing of a new product and/or brand. It's also shown that a deep understanding of marketing rules on a chosen platform can save both time and money in marketing.

Os processos de reciclagem e produção de agregados reciclados provenientes de resíduos de construção e demolição (RCD) estão se consolidando no Brasil, mas o seu emprego não ocorre na mesma proporção. A utilização desses em pavimentação, principalmente em camadas de base e sub-base, é considerada mais conveniente que em outras áreas, visto que não necessita de procedimentos avançados de reciclagem e utiliza os mesmos processos construtivos que agregados já consagrados, como britas graduadas. Entretanto, as recomendações normativas existentes remetem à caracterização dos agregados, sendo que as alusões ao seu comportamento mecânico são idênticas às impostas para britas graduadas. Além disso, a literatura existente é limitada frente a outros materiais alternativos, o que implica restrições ao seu emprego. Buscando atenuar essas incertezas, essa pesquisa tem como objetivo analisar o comportamento mecânico de agregados reciclados provenientes de RCD, de modo a identificar suas principais características e fornecer parâmetros de anteprojeto para o dimensionamento de pavimentos que utilizam esse material como camadas de suporte. Para isso, a primeira etapa comportou uma análise dos processos de beneficiamento dos agregados reciclados, de modo a identificar como influem nas suas características, o que foi alcançado concomitantemente a segunda etapa, que consistiu na análise dos agregados por meio de ensaios específicos de caracterização física e química. A terceira e principal etapa baseou-se na análise do comportamento mecânico, que além da determinação em equipamentos convencionais, também utilizou um equipamento triaxial de grande porte que comporta corpos de prova de 25 x 50 cm, permitindo a utilização da distribuição a ser empregada em campo. Essa etapa iniciou pela análise da compactação, realizada com curvas granulométricas e modos de umedecimento distintos, onde os mais promissores foram escolhidos para verificar a influência do método de compactação, sendo ele dinâmico ou vibratório. Após essas determinações, a análise concentrou-se no módulo de resiliência, na resistência ao cisalhamento e na deformação permanente, sendo que as evoluções da deformação permanente foram classificadas segundo a teoria do Shakedown. Os resultados demonstraram que a compactação causa a quebra de agregados, porém essa é menor quando utilizada compactação dinâmica. Os RCD apresentaram bom comportamento em relação deformações elásticas, com módulo de resiliência semelhantes aos apresentados por britas. Dado a diminuição de partículas lamelares causada pela quebra durante o processo de compactação, os valores mais representativos do ângulo de atrito e do intercepto coesivo foram 41° e 60 kPa, respectivamente. As análises das deformações realizadas em multiestágios demonstraram que, se utilizados em pavimentos com baixo de volume de tráfego, para razões de tensões σd / σ3 < 2 e tensões desvio σd ≤ 210 kPa, bases compostas de RCD não vão desenvolver deformações plásticas iniciais excessivas e o material vai responder elasticamente. Além disso, essas bases estão seguras contra falhas de cisalhamento. Em suma, as análises indicam que os RCD podem ser utilizados como materiais para bases e sub-bases de pavimentos de baixo volume de tráfego, dando um destino nobre a uma matéria-prima renovável e facilmente encontrada, que na maioria das vezes é desperdiçada e cuja geração aumenta constantemente. / Construction and Demolition Waste (CDW) recycling processes are consolidating in Brazil, but their use does not occur in the same proportion. The application of such in pavement, especially in base and sub-base layers, it is considered more convenient than in other areas because it does not require advanced recycling procedures and using the same constructive processes which aggregates already established, as graded gravel. However, existing normative recommendations refer to the characterization of the aggregates, and the allusions to their mechanical behavior are identical to those imposed on graded gravel. Moreover, the existing literature is limited compared to other alternative materials, implying restrictions on its use. Seeking to mitigate these uncertainties, this research aims to analyze the mechanical behavior of recycled aggregates from CDW, in order to identify its main characteristics and provide parameters for draft design of pavements that using this material as a support layer. For this, the first step involved an analysis of the aggregates recycling procedures, in order to identify the influence of this process in their characteristics, which were concomitantly reached the second stage consisting in the analysis of aggregate by specific tests of physical and chemistry characterization. The third and main step was based on the analysis of mechanical behavior, which besides determining in conventional equipment also utilized a large triaxial device that carries specimens of 25 x 50 cm, allowing the use of the distribution to be employed in field. This step began by analyzing the compaction performed with gradation curves and distinct modes of moistening, where the most promising were chosen to investigate the influence of compaction method, either dynamic or vibration. After these determinations, the analysis focused on the resilient modulus, shear strength and permanent strain, and the evolution of permanent strain were classified according to the theory of Shakedown. The results showed that compaction causes the aggregates break, but this is less when used dynamic compaction. The CDW had good behavior relative elastic strains, with resilient modulus similar to those presented by gravel. Since the decrease of lamellar particles caused by breakage during the compaction process, the most representative values of the friction angle and cohesive intercept were 41° and 60 kPa, respectively. The analysis of the permanent strain carried out in multistage demonstrated that if used in pavements with low traffic volume, for reasons of stress σd / σ3 < 2 and deviator stress σd ≤ 210 kPa, compound bases CDW will not develop excessive initial plastic strain and the material will respond elastically. In addition, these bases are secure against shear failure. In essence, the analysis indicates that the CDW can be used as materials for bases and sub-bases of low volume traffic floors, giving a noble destiny to a renewable raw material and easily found that most of the time is wasted and whose generation is constantly increasing.
