Otimização dos custos de exploração de um equipamento de refrigeração através da inércia térmica
Get PDFDissertação de mestrado em Engenharia Mecânica (área de especialização em Tecnologias Energéticas e
Ambientais)A refrigeração de bens alimentares é essencial na sociedade contemporânea, já que é responsável
pela conservação de bens essenciais para a sobrevivência de não só qualquer economia, mas também
da espécie humana. Uma das maiores preocupações de qualquer empresa deste ramo é a crescente
eficiência energética, uniformização de temperaturas e maior versatilidade de equipamentos. Foi com
este propósito que surgiu a proposta para a otimização dos custos de exploração de um equipamento de
frio positivo, através da inércia térmica
O principal desafio nesta dissertação seria a forma como se poderia adaptar um equipamento de
refrigeração convencional de frio positivo, em si já extremamente eficiente, para um equipamento com
um funcionamento semelhante, mas com um sistema alternativo, que tirasse partido de materiais de
mudança de fase, que através do calor latente pudessem fornecer inércia térmica e complementar o
ciclo de compressão a vapor tradicional. Desta forma, realizou-se uma análise ao equipamento de
refrigeração em estudo, neste caso o mural Futuro 2, caraterizando todos os seus componentes
termodinâmicos, de modo a entender se estes se encontravam bem dimensionados para a carga térmica
que o equipamento deve suportar. De modo a entender também qual a carga térmica que prejudica o
funcionamento do equipamento, estudaram-se os ganhos térmicos pela envolvente, as infiltrações
resultantes de aberturas de portas, a carga térmica resultante da reposição de produto no interior do
equipamento e finalmente os ganhos térmicos consequentes de equipamentos eletrónicos no local a
refrigerar. Pesando tudo isto, obteve-se o valor de 495 W, sendo que este deve ser o valor de referência
para o dimensionamento do evaporador e compressor do equipamento. Este valor é também essencial
para o dimensionamento do depósito de água, o material de mudança de fase escolhido, a implementar
nas costas do equipamento.
Após a definição do protótipo, este deverá ser testado numa câmara de ensaios, com condições
ambiente de 25 ºC e 60% de humidade relativa, para que se possa verificar se cumpre os requisitos
estabelecidos no início do projeto. Sendo o custo do equipamento por dia o principal critério de
comparação entre o equipamento inicial e o protótipo construído, os resultados obtidos foram uma
poupança de 0.06€/dia de funcionamento.Refrigeration of food products is essential in contemporary society, as it is responsible for
preserving essential goods for the survival not only of any economy but also of the human species. One
of the main concerns of any company in this industry is the increasing energy efficiency, temperature
uniformity, and greater equipment versatility. It was with this purpose that the proposal for optimizing the
operating costs of a positive cold equipment arose, through thermal inertia.
The main challenge in this dissertation would be how to adapt a conventional positive cold
refrigeration equipment, already extremely efficient, to equipment with a similar operation but with an
alternative system that takes advantage of phase change materials. Through latent heat, these materials
could provide thermal inertia and complement the traditional vapor compression cycle. In this way, an
analysis of the refrigeration equipment under study was carried out, in this case, the Futuro 2 multideck,
characterizing all its thermodynamic components to understand if they were well-sized for the thermal
load that the equipment must support.
To understand the thermal load that affects the equipment's operation, gains from the
surroundings, infiltrations resulting from door openings, the thermal load resulting from product
replacement inside the equipment, and finally, the thermal gains from electronic equipment in the cooling
area were studied. Considering all of this, a value of 495 W was obtained, which should be the reference
value for sizing the evaporator and compressor of the equipment. This value is also essential for sizing
the water tank, the chosen phase change material, to be implemented at the back of the equipment.
After defining the prototype, it should be tested in a test chamber, with ambient conditions of 25 ºC
and 60% relative humidity, to verify if it meets the requirements established at the beginning of the project.
As the equipment's daily cost is the main criterion for comparison between the initial equipment and the
built prototype, the results obtained were a savings of 0.06€/day of operation
Análise detalhada do comportamento térmico de um edifício de serviços com vista a otimização energética
Get PDFDissertação de mestrado integrado em Engenharia MecânicaA forma insustentável como a humanidade utiliza os recursos energéticos existentes e as
consequências desta exploração do planeta têm-se tornado uma preocupação global,
conduzindo à adoção de medidas e políticas de racionalização e eficiência energética.
O setor dos edifícios é responsável por uma parcela considerável do consumo de energia
mundial. Na Europa, o setor construtivo tem atravessado uma transformação energética e
ambiental visando cumprir as metas propostas pela União Europeia. Mais concretamente, em
Portugal, a transposição das políticas europeias tem a vindo decorrer desde 2006, aquando
da aprovação do Sistema Nacional de Certificação Energética (SCE).
As crescentes exigências de conforto térmico aliadas às normas de sensibilização económica
e energética exaltam a importância das ferramentas de simulação dinâmica no processo de
conceção de edifícios. A presente dissertação pretende, numa primeira instância, selecionar
um programa de simulação dinâmica detalhada e posteriormente, através do mesmo, avaliar
o desempenho energético de um edifício com vista à perceção dos alvos de melhoria do
mesmo e cálculo da respetiva classe energética.
As soluções construtivas do edifício, os equipamentos técnicos e o enquadramento
regulamentar foram analisados e introduzidos no software DesignBuilder. Os resultados
relativos aos ganhos internos do edifício indicaram a predominância dos ganhos solares (60%).
Esta preponderância, aliada a outros fatores, resulta numa discrepância acentuada entre as
necessidades de arrefecimento e de aquecimento do modelo. Os consumos energéticos
obtidos, revelaram um elevado consumo relativo a equipamentos interiores e iluminação. O
cálculo do rácio de classe energética resultou numa classificação B-.
Por fim, procedeu-se ao estudo de três medidas de melhoria, projetadas para colmatar as
falhas do modelo evidenciadas pela simulação. Selecionaram-se duas destas medidas, que em
conjunto, resultaram numa redução do consumo energético de 27 MWh (44.9%), obtenção
da classe energética A e um período de retorno simples de 6 anos e 7 meses. Para além da
poupança energética, esta solução alcançou a classificação NZEB.The unsustainable way in which mankind uses existing energy resources and the
consequences of this insatiable exploitation of the planet has become a global concern,
leading to the adoption of measures and policies of rationalisation and energy efficiency.
The building sector is responsible for a considerable portion of the world's energy
consumption. In Europe, the construction sector has undergone an energy and environmental
transformation aimed at meeting the targets proposed by the European Union. More
specifically, in Portugal, the transposition of European policies has been taking place since
2006, when the Sistema de Certificação Energética (SCE) was approved.
The growing demands of thermal comfort combined with the economic and energy awareness
standards exalt the importance of dynamic simulation tools in the process of building design.
The present dissertation intends, in a first instance, to select a dynamic simulation program
and then, through it, to evaluate the energy performance of a building in order to perceive its
improvement targets and calculate its energy class.
The constructive solutions of the building, the technical equipment and the regulatory
framework were analysed and introduced in the DesignBuilder software. The results
concerning the internal gains of the building indicated the predominance of solar gains (60%).
This preponderance, combined with other factors, results in a marked discrepancy between
the cooling and heating needs of the model. The energy consumption obtained, revealed a
high consumption related to indoor equipment and lighting. The calculation of the energy
class ratio resulted in a B- classification.
Finally, three improvement measures were studied, designed to fill the gaps in the model
highlighted by the simulation. Two measures were selected, resulting in an energy
consumption reduction of 27 MWh (44.9%), a class improvement to A and a payback period
of 6 years and 7 months. In addition to the energy savings, this solution achieved NZEB rating
Conceção, desenvolvimento e projeto de um equipamento de humidificação de placas de hóstias
Get PDFDissertação de mestrado integrado em Engenharia MecânicaO objetivo geral desta dissertação passa pela melhoria do processo de humidificação de placas de hóstia. As placas de hóstia têm o formato retangular e são resultado da cozedura da massa que constitui as hóstias.
Inicialmente estudou-se o processo produtivo de hóstias, no qual se enquadra o processo de humidificação, de forma a compreender todas as etapas necessárias à produção de hóstias. Este estudo permitiu ainda perceber a importância da humidificação no processo produtivo de hóstias. Com o objetivo de conhecer as soluções já existentes, elaborou-se um estudo de mercado.
Posteriormente estudou-se o material das placas de hóstia, de forma a compreender o nível de humidificação ideal. Fez-se ainda um trabalho experimental que permitiu perceber a temperatura e humidade relativa, ideais, para que o processo seja o mais rápido possível.
De seguida foram elaborados diversos ensaios à câmara de humidificação 1, com o objetivo de entender a razão pela qual o processo de humidificação utilizado não permite uma cadência suficiente para dar resposta à etapa de corte. Conhecidos os pontos fracos da câmara de humidificação 1, foram propostas melhorias para promover um processo de humidificação mais eficiente.
Com o propósito de promover o projeto de um novo equipamento de humidificação, realizou-se um projeto conceptual na procura de soluções alternativas que consigam responder aos objetivos iniciais do projeto.
O passo seguinte passou pela execução do projeto detalhado do equipamento, onde foram selecionados os componentes necessários para o correto funcionamento da máquina projetada.
Por fim, realizou-se o projeto de automação do equipamento, permitindo um controlo automático do funcionamento do mesmo.The general objective of this dissertation is to improve the host plates humidification process. The host plates are rectangular in shape and are the result of cooking the dough that forms the host.
Initially it was studied the productive process of hosts, in which fits the process of humidification, in order to understand all the necessary steps to produce hosts. This study also allowed to understand the importance of humidification in the hosts production process. In order to know the existing solutions, it was conducted a market study.
After that, it was studied the material of the host plates in order to understand the ideal level of humidification. Also, it has been done an experimental work to make it possible to understand the ideal temperature and relative humidity to make the process as fast as possible.
Following, several tests were made to the humidification chamber 1, intending to understand why the used humidification process does not allow enough cadence to respond to the cutting station. Knowing the weaknesses of the humidification chamber 1, improvements were proposed to promote a more efficient humidification process.
In order to promote the design of a new humidification equipment, it was carried out a conceptual design in search for alternative solutions that could meet the initial objectives of the project.
The next step was the execution of the detailed design of the equipment, where the necessary components for the correct operation of the designed machine were selected.
Finally, it was carried out the automation design of the equipment, allowing an automatic control of its operation

The trombone as portrayed in Portuguese iconography during the sixteenth and early seventeenth centuries
No full textThis article studies eleven sixteenth and seventeenth century iconographical sources depicting slide brass instruments, by both Portuguese and foreign artists active in Portugal, as well as foreign artists depicting Portuguese scenes. This study addresses questions concerning aspects of trombone technique that have not previously been considered and may have implications in the way the trombone was understood elsewhere in Europe. It focuses on aspects of technique depicted that may be representative of the trombone’s contemporary design and performance and therefore the manner in which the instrument was held and indeed played. Finally, this article suggests a transitional technical period when the way of holding the single-slide trumpet may have been used to play the trombone.Publisher PD

Black-Litterman and ortogonal GARCH models for a portfolio of bonds issued by the National Treasury
No full textUma grande dificuldade da gestão financeira é conseguir associar métodos quantitativos às formas tradicionais de gestão, em um único arranjo. O estilo tradicional de gestão tende a não crer, na devida medida, que métodos quantitativos sejam capazes de captar toda sua visão e experiência, ao passo que analistas quantitativos tendem a subestimar a importância do enfoque tradicional, gerando flagrante desarmonia e ineficiência na análise de risco. Um modelo que se propõe a diminuir a distância entre essas visões é o modelo Black-Litterman. Mais especificamente, propõe-se a diminuir os problemas enfrentados na aplicação da teoria moderna de carteiras e, em particular, os decorrentes da aplicação do modelo de Markowitz. O modelo de Markowitz constitui a base da teoria de carteiras há mais de meio século, desde a publicação do artigo Portfolio Selection [Mar52], entretanto, apesar do papel de destaque da abordagem média-variância para o meio acadêmico, várias dificuldades aparecem quando se tenta utilizá-lo na prática, e talvez, por esta razão, seu impacto no mundo dos investimentos tem sido bastante limitado. Apesar das desvantagens na utilização do modelo de média-variância de Markowitz, a idéia de maximizar o retorno, para um dado nível de risco é tão atraente para investidores, que a busca por modelos com melhor comportamento continuou e é neste contexto que o modelo Black-Litterman surgiu. Em 1992, Fischer Black e Robert Litterman publicam o artigo Portfolio Optimization [Bla92], fazendo considerações sobre o papel de pouco destaque da alocação quantitativa de ativos, e lançam o modelo conhecido por Black-Litterman. Uma grande diferença entre o modelo Black-Litterman e um modelo média-variância tradicional é que, enquanto o segundo gera pesos em uma carteira a partir de um processo de otimização, o modelo Black-Litterman parte de uma carteira de mercado em equilíbrio de longo prazo (CAPM). Outro ponto de destaque do modelo é ser capaz de fornecer uma maneira clara para que investidores possam expressar suas visões de curto prazo e, mais importante, fornece uma estrutura para combinar de forma consistente a informação do equilíbrio de longo prazo (priori) com a visão do investidor (curto prazo), gerando um conjunto de retornos esperados, a partir do qual os pesos em cada ativo são fornecidos. Para a escolha do método de estimação dos parâmetros, levou-se em consideração o fato de que matrizes de grande dimensão têm um papel importante na avaliação de investimentos, uma vez que o risco de uma carteira é fundamentalmente determinado pela matriz de covariância de seus ativos. Levou-se também em consideração que seria desejável utilizar um modelo flexível ao aumento do número de ativos. Um modelo capaz de cumprir este papel é o GARCH ortogonal, pois este pode gerar matrizes de covariâncias do modelo original a partir de algumas poucas volatilidades univariadas, sendo, portanto, um método computacionalmente bastante simples. De fato, as variâncias e correlações são transformações de duas ou três variâncias de fatores ortogonais obtidas pela estimação GARCH. Os fatores ortogonais são obtidos por componentes principais. A decomposição da variância do sistema em fatores de risco permite quantificar a variabilidade que cada fator de risco traz, o que é de grande relevância, pois o gestor de risco poderá direcionar mais facilmente sua atenção para os fatores mais relevantes. Ressalta-se também que a ideia central da ortogonalização é utilizar um espaço reduzido de componentes. Neste modelo de dimensão reduzida, suficientes fatores de risco serão considerados, assim, os demais movimentos, ou seja, aqueles não capturados por estes fatores, serão considerados ruídos insignificantes para este sistema. Não obstante, a precisão, ao desconsiderar algumas componentes, irá depender de o número de componentes principais ser suficiente para explicar grande parte da variação do sistema. Logo, o método funcionará melhor quando a análise de componentes principais funcionar melhor, ou seja, em estruturas a termo e outros sistemas altamente correlacionados. Cabe mencionar que o GARCH ortogonal continua igualmente útil e viável quando pretende-se gerar matriz de covariâncias de fatores de risco distintos, isto é, tanto dos altamente correlacionados, quanto daqueles pouco correlacionados. Neste caso, basta realizar a análise de componentes principais em grupos correlacionados. Feito isto, obtêm-se as matrizes de covariâncias utilizando a estimação GARCH. Em seguida faz-se a combinação de todas as matrizes de covariâncias, gerando a matriz de covariâncias do sistema original. A estimação GARCH foi escolhida pois esta é capaz de captar os principais fatos estilizados que caracterizam séries temporais financeiras. Entende-se por fatos estilizados padrões estatísticos observados empiricamente, que, acredita-se serem comuns a um grande número de séries temporais. Séries financeiras com suficiente alta frequência (observações intraday e diárias) costumam apresentar tais características. Este modelo foi utilizado para a estimação dos retornos e, com isso, obtivemos todas as estimativas para que, com o modelo B-L, pudéssemos gerar uma carteira ótima em um instante de tempo inicial. Em seguida, faremos previsões, obtendo carteiras para as semanas seguintes. Por fim, mostraremos que a associação do modelo B-L e da estimação GARCH ortogonal pode gerar resultados bastante satisfatórios e, ao mesmo tempo, manter o modelo simples e gerar resultados coerentes com a intuição. Este estudo se dará sobre retornos de títulos de renda fixa, mais especificamente, títulos emitidos pelo Tesouro Nacional no mercado brasileiro. Tanto a escolha do modelo B-L, quanto a escolha por utilizar uma carteira de títulos emitidos pelo Tesouro Nacional tiveram como motivação o objetivo de aproximar ferramentas estatísticas de aplicações em finanças, em particular, títulos públicos federais emitidos em mercado, que têm se tornado cada vez mais familiares aos investidores pessoas físicas, sobretudo através do programa Tesouro Direto. Ao fazê-lo, espera-se que este estudo traga informações úteis tanto para investidores, quanto para gestores de dívida, uma vez que o modelo média-variância presta-se tanto àqueles que adquirem títulos, buscando, portanto, maximizar retorno para um dado nível de risco, quanto para aqueles que emitem títulos, e que, portanto, buscam reduzir seus custos de emissão a níveis prudenciais de risco.One major challenge to financial management resides in associating traditional management with quantitative methods. Traditional managers tend to be skeptical about the quantitative methods contributions, whereas quantitative analysts tend to disregard the importance of the traditional view, creating clear disharmony and inefficiency in the risk management process. A model that seeks to diminish the distance between these two views is the Black-Litterman model (BLM). More specifically, it comes as a solution to difficulties faced when using modern portfolio in practice, particularly those derived from the usage of the Markowitz model. Although the Markowitz model has constituted the basis of portfolio theory for over half century, since the publication of the article Portfolio Selection [Mar52], its impact on the investment world has been quite limited. The Markowitz model addresses the most central objectives of an investment: maximizing the expected return, for a given level of risk. Even though it has had a standout role in the mean-average approach to academics, several difficulties arise when one attempts to make use of it in practice. Despite the disadvantages of its practical usage, the idea of maximizing the return for a given level of risk is so appealing to investors, that the search for models with better behavior continued, and is in this context that the Black-Litterman model came out. In 1992, Fischer Black and Robert Litterman wrote an article on the Black-Litterman model. One intrinsic difference between the BLM and a traditional mean-average one is that, while the second provides the weights of the assets in a portfolio out of a optimization routine, the BLM has its starting point at the long-run equilibrium market portfolio(CAPM). Another highlighting point of the BLM is the ability to provide one clear structucture that is able to combine the long term equilibrium information with the investors views, providing a set of expected returns, which, together, will be the input to generate the weights on the assets. As far as the estimation process is concerned, and for the purpose of choosing the most appropriate model, it was taken into consideration the fact that the risk of a portfolio is determined by the covariation matrix of its assets and, being so, matrices with large dimensions play an important role in the analysis of investments. Whereas, provided the application under study, it is desirable to have a model that is able to carry out the analysis for a considerable number of assets. For these reasons, the Orthogonal GARCH was selected, once it can generate the matrix of covariation of the original system from just a few univariate volatilities, and for this reason, it is a computationally simple method. The orthogonal factors are obtained with principal components analysis. Decomposing the variance of the system into risk factors is highly important, once it allows the risk manager to focus separately on each relevant source of risk. The main idea behind the orthogonalization consists in working with a reduced dimension of components. In this kind of model, sufficient risk factors are considered, thus, the variability not perceived by the model will be considered insigficant noise to the system. Nevertheless, the precision, when not using all the components, will depend on the number of components be sufficient to explain the major part of the variability. Moreover, the model will provide reasonable results depending on principal component analysis performing properly as well, what will be more likely to happen, in highly correlated systems. It is worthy of note that the Orthogonal GARCH is equally useful and feasible when one intends to analyse a portfolio consisting of assets across various types of risk, it means, a system which is not highly correlated. It is common to have such a portfolio, with, for instance, currency rates, stocks, fixed income and commodities. In order to make it to perform properly, it is necessary to separate groups with the same kind of risk and then carry out the principal component analysis by group and then merge the covariance matrices, producing the covariance matrix of the original system. To work together with the orthogonalization method, the GARCH model was chosen because it is able to draw the main stylized facts which characterize financial time series. Stylized facts are statistical patterns empirically observed, which are believed to be present in a number of time series. Financial time series which sufficient high frequency (intraday, daily and even weekly) usually present such behavior. For estimating returns purposes, it was used a ARMA model, and together with the covariance matrix estimation, we have all the parameters needed to perform the BLM study, coming out, in the end, with the optimal portfolio in a given initial time. In addition, we will make forecasts with the GARCH model, obtaining optimal portfolio for the following weeks. We will show that the association of the BLM with the Orthogonal GARCH model can generate satisfactory and coherent with intuition results and, at the same time, keeping the model simple. Our application is on fixed income returns, more specifically, returns of bonds issued in the domestic market by the Brazilian National Treasury. The motivation of this work was to put together statistical tolls and finance uses and applications, more specifically those related to the bonds issued by the National Treasuy, which have become more and more popular due to the \"Tesouro Direto\" program. In conclusion, this work aims to bring useful information either for investors or to debt managers, once the mean-variance model can be useful for those who want to maximize return at a given level or risk as for those who issue bonds, and, thus, seek to reduce their issuance costs at prudential levels of risk
Project Point Pedro: A multidisciplinary design study of the Point Pedro fishery harbour
No full textIn Sri Lanka, the government and the Liberation Tigers of Tamil Eelam waged a civil war between 1983 and 2009. During this period the social and economic development in the north and east of the country was disrupted. Due to this disruption a development opportunity for this region is the expansion of the fishery industry. In 2016, the Sri Lankan government proposed the Northern Province Sustainable Fisheries Development Project, in which the construction of a harbour at Point Pedro in the Jaffna District is included. This harbour should become the second largest fishery harbour in Sri Lanka.This report covers the design study of the Point Pedro harbour project, the goal of this study is to design a safe, economically efficient and socially accepted harbour at Point Pedro. To achieve this goal, the following research question “How can safety, economic efficiency and environmental impact be combined optimally in a harbour design for Point Pedro in the Jaffna District?” is answered.In figure XX, the final design of the harbour can be seen. This design is focused on the optimal combination between safety, economic efficiency and environmental impact. Because these criteria are conflicting, they are prioritized as follows: (1) safety, (2) economic efficiency and (3) environmental impact. Safety is provided by constructing breakwaters around the harbour, providing sheltered water conditions in the harbour basin. Also, the harbour entrance is constructed in a way that monsoon waves cannot directly intrude into the basin. Economic efficiency is accounted for by constructing the quay wall close to the central located fish processing facilities. This optimizes the supply chain, resulting in a smaller loss in the fish production (compared to the current situation). The costs are optimized by reusing all dredged material inside the breakwater or for land reclamation. Additionally, the location of the harbour entrance is minimizing the sailing routes as much as possible, without creating safety issues due to wave intrusion. Finally, the negative effects of social impact are limited by involving local fishermen and residents during the entire development process. Because these stakeholders are potential blockers of the project, it is important to include their opinions in the design. This can also be done by broadening the scope, in which touristic facilities and accommodations can be included in the project. Other negative impacts of the harbour can be either mitigated or minimized. However, because the environmental impact is determined as the least important criteria, it is not able to solve every issue. This design is considered to be the most optimal combination for the harbour design of Point Pedro, regarding the criteria of safety, economic efficiency and environmental impact. It is recommended to EML Consultants that three characteristics of the proposed design should be implemented in their final design for Point Pedro: (1) apply building on the reef for land reclamation inside the harbour, (2) cluster the fish processing facilities near the unloading quay walls, because it optimizes the fish supply chain and reduces fish loss, and (3) construct the jetties for large boats (in the east of the harbour) as proposed, because it optimizes manoeuverability inside the harbour using minimal space. The final recommendation is to perform additional research to make a more accurate design, as the main limitation of the report is the limited amount of available data. Additional research should be done in the fields of; wave data, ground conditions over the entire harbour basin, cost estimation and sedimentation. This report is made on behalf of EML Consultants in Colombo, Sri Lanka.MDP 236Project Point PedroThe Northern Province Sustainable Fisheries Development ProjectMultidisciplinary Projec
PEDAGOGUES AND TAES AT COLÉGIO PEDRO II - Historical and Identitarian Notes.
No full textThe article aims at relating the process of development of a professional identity among pedagogues in Brazil, the historical path of Pedagogy as a course, the educational legislation in Brazil and Colégio Pedro II. Colégio Pedro II is an educational institution of excellence, whose history, of national importance, has dealt very little with working relationships outside the classroom. For this reason, the objective of this study is to promote discussions which, regarding professional identities, take into consideration not only the subject, but also the group to which they belong. In terms of theoretical support, the author relies on the sociological approach discussed by Dubar (2005) and the analysis of the history of pedagogy courses carried out by Silva (2006). In addition, other relevant instances are public selection notices for admission to Colégio Pedro II from 1946 to 2015, academic studies upon the theme and responses from entities and professionals in the field of Education upon the pedagogy course programmes. The author takes into account that identities of both the pedagogue and the educational matters technician (TAE) are entangled at institutional level, which shows that the institution is still unsure of what to require and demand from both professionals. Although these educational matters professionals have licentiate degrees in other areas, it is still expected at institutional level that they act as specialists in education (pedagogue)
