[pt] O planejamento da expansão da transmissão tem por objetivo identificar o conjunto de novas linhas de transmissão que serão instaladas na rede elétrica, a fim de garantir a segurança e a qualidade do sistema, atendendo ao crescimento da demanda. No Brasil, o primeiro estágio do planejamento consiste em definir e avaliar o corredor para locação das linhas candidatas. Nesta etapa são definidas informações como cabo escolhido, preços médios, tempo de comissionamento, impactos socioambientais e informações sobre a região. No estágio seguinte ocorre o leilão de transmissão em que vários investidores competem pelos lotes de transmissão. No último estágio, o ganhador do leilão é o responsável pela instalação e comissionamento da linha de transmissão. Apesar do levantamento feito no estágio inicial, os projetos de linha de transmissão podem sofrer atrasos e aumentos no custo final, principalmente, por questões de licenciamentos ambientais, desvios do traçado devido a travessias e interferências com áreas protegidas. A presente dissertação propõe metodologia para dimensionamento e precificação da linha de transmissão, ambos de acordo com os critérios e banco de dados da ANEEL, de forma a acelerar e facilitar o processo de planejamento. Com o intuito de evitar atrasos e prever interferências socioambientais, a segunda parte do trabalho apresenta uma metodologia que consiste em localizar e identificar cruzamentos e interferências com áreas protegidas de caráter ambiental e/ou infraestrutural no território brasileiro, a partir das coordenadas do traçado da linha de transmissão em análise. A terceira parte do trabalho verifica, a partir dos resultados anteriores, o impacto no planejamento da expansão da transmissão através de um modelo de programação linear inteira mista considerando fluxo de potência CC, despacho econômico e critério N-1. / [en] The transmission expansion planning aims at identifying a set of new power lines to be installed on the grid, in order to guarantee the reliability and quality of the system, meeting the demand growth. In Brazil, the first stage of planning consists of defining e survey the corridor for the transmission line siting. At this stage it is defined data such as conductor chosen, average prices, commissioning time, socioenvironmental impacts and information about the region. In the following stage, occurs the auction which several investors compete for the transmission lots. In the last stage, the winner of the auction becomes responsible for the installation and commissioning. Despite the survey of the initial stage, the transmission lines undergo delays and additional costs, mainly, due to environmental licensing, changes of the defined route due to crossing and interferences with protected areas. The present dissertation proposes a methodology to design and price the transmission line, both accordingly to the ANEEL database and criteria, in order to accelerate and facilitate the planning process. Aiming to avoid delays and foreseeing socioenvironmental impacts, the second part of the dissertation presents a methodology that consists of locating and identifying crossings and interferences with protected areas of environmental and/or infrastructural aspect on the Brazilian territory, from the coordinates of the transmission line route in analysis. The third part verifies, from the previous results, the impact on the transmission expansion planning through a model based on a mixed-integer linear programming, considering a DC power flow, unit commitment and N-1 criteria

Teknikämnet är i ständig förändring i och med den snabba teknikutvecklingen, medan klassrummets utseende i princip inte har förändrats sedan 1840-talet. Därför lär inte det traditionella klassrummet vara anpassat för teknikämnet och dess undervisning idag. Syftet har varit att undersöka, analysera och utforma förslag på hur teknikklassrum kan utformas. Vidare var syftet att utvärdera förslagen med utgångspunkt i perspektivet att klassrummet ska främja projektbaserad undervisning. För att uppnå syftet genomfördes en litteraturstudie samt datainsamling bestående av intervjuer och fokusgrupper med lärare och elever. En fenomenografisk analys utfördes på empirin för att finna uppfattningar om vad som är viktigt vid utformning av ett klassrum. Analysen visade att den fysiska inomhusmiljön, möblering, material i klassrummet, inspiration för elever samt vad som finns i närheten av klassrummet, är viktigt att ta hänsyn till vid utformning av teknikklassrummet. Flexibilitet verkade vara den enskilt viktigaste faktorn att ta hänsyn till vid klassrumsutformning, därför behöver flexibilitet genomsyra alla kategorier. De fysiska miljöfaktorer som lärare ansåg påverkar projektbaserad undervisning var material, ljudvolym, estetik och elevernas placering. När ett klassrum ska utformas för att främja projektbaserad undervisning behöver skolan ta hänsyn till vilka typer av projekt klassrummet ska möjliggöra eftersom olika projekt kräver olika fysiska miljöer. Fem klassrumsförslag för teknikämnet utformades främst med hjälp av den fenomenografiska analysen. En utvärdering av klassrumsförslagen gjordes och enligt respondenterna passar två av förslagen, eller en kombination av dem, bäst för projektbaserad undervisning. / Technology is a Swedish school subject that is in constant change because of the rapid rate of technology development, while the classroom appearance, in principle, has not changed since the 1840s. Hence, the traditional classroom might not be suited for the subject of technology and its teaching. The aim has been to investigate, analyze and design proposals on how a classroom for the technology subject can be designed. Furthermore, the aim was to evaluate the proposals based on the perspective that the classroom should promote projectbased teaching. To achieve the aim, literature studies and data collection was conducted consisting of interviews and focus groups with teachers and students. A phenomenological analysis was conducted to find perceptions of what is important when designing a classroom. The analysis showed that the physical indoor environment, furnishings and materials in the classroom, inspiration for students as well as what is in the vicinity of the classroom are important to be taken into consideration when designing a classroom for the technology subject. Flexibility seemed to be the single most important factor to take into account in classroom design, therefore, flexibility needs to permeate all categories. The physical environmental factors that teachers thought influenced project-based teaching were material, sound volume, aesthetics and students' placement. When a classroom is to be designed to promote project-based teaching, the school needs to take into account what kind of projects the classroom should enable because different projects require different physical environments. Five classroom proposals for the technology subject were designed primarily using the phenomenological analysis. An evaluation of the classroom proposals was made and according to the respondents, two of the proposals, or a combination of them, are best suited for project-based teaching.

För att uppnå målen med Agenda 2030 behöver fler satsningar göras på innovation och digitala lösningar, såväl inom den offentliga sektorn som inom industrisektorn. Beträffande den ekonomiska hållbarheten har den svenska byggindustrin i dagsläget möjlighet till sparande av mångmiljardbelopp årligen och digitalisering spelar en nyckelroll i att lyckas uppnå det. Det är viktigt med samverkan och en snabb byggprocess, varför digitala verktyg som förbättrar och kan påskynda den är av intresse för hela branschen, i synnerhet sådana som kan användas under projekteringsfasen. Denna studie avser därför att undersöka hur processen av beräkning av byggnadsverks kostnadskalkyler kan automatiseras, genom användning av den data som finns i den digitala byggmodellen. Därför programmeras en applikation som kopplar samman modelldata och kostnadsdata, med hjälp av Byggnadsinformationsmodellering (BIM), programmering och tvåväga informationsflöden. Studien illustrerar genom exemplifiering processen av programmering och undersöker hur digitalisering – i såväl teori som praktik – kan användas och tillämpas på byggindustrin. Applikationen är en produkt som utvecklas och metodkapitlet initieras därför av en designprocess; specificering av krav, funktioner som uppfyller kraven, attribut som motsvarar dessa funktioner och till sist hur de sammanfogas för att tillsammans skapa produkten. Detta följs av en litteraturstudie som utfördes dels för att samla fakta om programmering och digitala möjligheter inom byggbranschen, dels för att undersöka liknande studier som gjorts tidigare. Slutligen insamlades kostnader till beräkning av schablonvärden för olika typobjekt som sedan kan användas i tandem med modellen för att skapa kostnadskalkylen. Inledningsvis beskriver resultatet ingående en förenklad variant av applikationen, i syfte att närmare illustrera programmeringsprocessen. Därpå följer beskrivningen av programmeringen av applikationen som programmerats för denna studie. Det slutgiltiga resultatet blev en applikation som automatiserar beräkning av en kostnadskalkyl och en studie som beskriver applikationens sammanhang samt metodiken av att programmera den. / In order to achieve the Sustainable Development Goals (SDGs) defined for Agenda 2030, more investments are needed in innovation and digitalized solutions, as much so in the public sector as in the industry sector. When it comes to the economical sustainability, the Swedish construction industry has possibilities of saving multi-billion sums yearly, and digitalization is playing a key part in making that possible. Both cooperation and an efficient construction process are of importance, why digital tools that can improve and speed up this process are of interest, especially ones that can be used during the design phase. The purpose of this study is to examine how the process of calculating a cost estimate for a civil construction can be automated, using the data in its digital model. An application is therefore programmed, combining model data and cost data, through Building Information Modelling (BIM), programming and two-way data exchange. The study illustrates the process of programming and examines how digitalization can be applied to the constructional industry, both in theory and practice. The application development process is part of the study, why the method chapter is initiated by its design process; specifying customer needs, functions that fulfil the needs, attributes that match these functions and lastly how they come together to make the product. This is then followed by the literature overview, which was done partly to gather information about programming and digital possibilities within the construction industry, and partly for relating this study to similar ones done before. Lastly costs have been collected for calculating template values for different modelling objects, which then can be used together with the model to produce the cost estimate. Initially the result explains a simplified version of the application in-depth, for the purpose of illustrating the programming process thoroughly. That is then followed by the programming of the actual application. The final result was an application that automizes calculation of a cost estimate, and a study that describes its context and the methodology of programming it.

The introduction of Outcomes-Based Curriculum 2005, has meant that the learning area of Life Orientation has undergone significant changes. These changes encompass both the scope of the learning area of Life Orientation, and the implementation of Life Orientation. The aim of this investigation has been to examine the implications of Outcomes-Based Curriculum 2005, for Life Orientation as well as to propose a method of assisting this implementation. The training of facilitators has met with mixed results and there is still confusion surrounding Curriculum 2005, and the learning area of Life Orientation. The development of an implementation model was therefore proposed and developed to assist Life Orientation facilitators to make the transition from a theoretical understanding to the practical implementation. The results of the study determined that the facilitators were overwhelmingly in support of the implementation model. They found it provided a logical and comprehensive framework, which would be helpful in assisting them with planning their learning programmes. In order to understand more fully the effectiveness of the implementation model in the classroom reality, it will however be necessary to undertake a study over a longer term with participating facilitators. A number of other issues also were investigated as part of this study. From this it was determined that facilitators feel they require more training to implement an Outcomes-Based appro'ach particularly with regard to assessment. Facilitators have also not yet fully understood what constitutes the learning area of Life Orientation, nor their tasks as a facilitator. / Psychology of Education / D. Ed. (Psychology of Education)

Despite widespread recognition by science educators, researchers and K-12 frameworks that scientific inquiry should be an essential part of science education, typical classrooms and assessments still emphasize rote vocabulary, facts, and formulas. One of several reasons for this is that the rigorous assessment of complex inquiry skills is still in its infancy. Though progress has been made, there are still many challenges that hinder inquiry from being assessed in a meaningful, scalable, reliable and timely manner. To address some of these challenges and to realize the possibility of formative assessment of inquiry, we describe a novel approach for evaluating, tracking, and scaffolding inquiry process skills. These skills are demonstrated as students experiment with computer-based simulations. In this work, we focus on two skills related to data collection, designing controlled experiments and testing stated hypotheses. Central to this approach is the use and extension of techniques developed in the Intelligent Tutoring Systems and Educational Data Mining communities to handle the variety of ways in which students can demonstrate skills. To evaluate students' skills, we iteratively developed data-mined models (detectors) that can discern when students test their articulated hypotheses and design controlled experiments. To aggregate and track students' developing latent skill across activities, we use and extend the Bayesian Knowledge-Tracing framework (Corbett & Anderson, 1995). As part of this work, we directly address the scalability and reliability of these models' predictions because we tested how well they predict for student data not used to build them. When doing so, we found that these models demonstrate the potential to scale because they can correctly evaluate and track students' inquiry skills. The ability to evaluate students' inquiry also enables the system to provide automated, individualized feedback to students as they experiment. As part of this work, we also describe an approach to provide such scaffolding to students. We also tested the efficacy of these scaffolds by conducting a study to determine how scaffolding impacts acquisition and transfer of skill across science topics. When doing so, we found that students who received scaffolding versus students who did not were better able to acquire skills in the topic in which they practiced, and also transfer skills to a second topic when was scaffolding removed. Our overall findings suggest that computer-based simulations augmented with real-time feedback can be used to reliably measure the inquiry skills of interest and can help students learn how to demonstrate these skills. As such, our assessment approach and system as a whole shows promise as a way to formatively assess students' inquiry.

This master thesis is a case study, in the experience industry, of prototypes in the early stage of the innovation process – the front end of innovation. The innovation is augmented reality (AR) that adds digital made graphics or information in the user's environment. To answer the research questions and to fulfill the purpose of this thesis, which is to gain an understanding of the role of a prototype in an innovation process, a prototype was created. The designing tools used for developing the prototype were brainstorming and storyboarding. The prototype presents a concept of using AR-glasses at an ice hockey venue. A workshop was carried out for evaluating the finished prototype, using the "thinking hats"-method. The conclusion of this study is that a prototype can be used as a starting point for further creativity by creating a common perspective of a technology at the front end of innovation. Further on, it was discovered that a prototype can be good to use earlier in their innovation process, to accelerate the process. In the process of designing the prototype, it was shown that the creation is iterative, rather than linear.

La finalité de ce travail exploratoire, inscrit dans le cadre d’une didactique professionnelle du design naissante, est de comprendre l’incidence de l’alternance sur les apprentissages d’étudiants en design. Dans ce but, les connaissances ou savoirs impliqués et les représentations que les prescriptions proposent sont extraits puis mis en regard des représentations que les étudiants construisent de l’activité de conception en tant qu’objet social ou en jeu dans les activités d’apprentissage. Pour aborder ces représentations décrites ou construites, puis leur incidence sur l’activité de conception et sur les apprentissages, il est fait appel à un champ théorique multidisciplinaire et à un cadre méthodologique dialectique s’appuyant sur une analyse curriculaire et sur une analyse de l’activité des étudiants-apprentis. Les résultats mettent en lumière des représentations, parfois antagonistes, de l’activité de conception et de la profession de designer. Ils montrent que l’alternance des temps et des lieux d’apprentissage est un révélateur, pour les étudiants, des spécificités de l’activité de conception au sein de chacun des environnements. Ainsi, les environnements « organisants » et « capacitants » du curriculum réel, impensés dans le prescrit, modifient et régulent l’activité et le développement des compétences. Enfin, la production de connaissances, prescrite par le curriculum dans la cadre d’un « mémoire de recherche », permet aux apprentis-designers-chercheurs de développer des formes d’expertises qui interrogent sur les interactions entre savoirs pour agir et métaconnaissances pour concevoir et semblent redéfinir la représentation de la compétence de conception. / The purpose of this exploratory work, grounded on an emerging professional pedagogy of design, is to understand the impact of work-linked training in design on the learning of the design activity by students. To that end, the knowledge involved is extracted, juxtaposed with the representations that the requirement offers, and then set against the representations that students build of design activity as a social object as well as those involved in learning activities. Therefore, the theoretical field which is used is multidisciplinary. It induces a dialectical methodologic framework based both on a curricular analysis, necessary to understand the observed teaching situations, and on an analysis of the students’ activities. The outcomes shed light on these (sometimes conflicting) representations of creative design activity and of the designer’s profession. Outcomes also show the alternating times and places of learning situations reveal to the students the specificity of both designing situation. Thus, the “organizing environments” of the real curriculum and untaught within the required one, modify and regulate the system of interactions and the development of the students’ design skills. Moreover, the exchange device induces a timeline and “enabling” working and learning environments. Finally, the production of knowledge, required by the curriculum through the “research thesis”, allows the “apprentices-designers-researchers” to develop forms of expertise that question the interactions between knowledge to act and meta-knowledge to design and seems to redefine the representation of the design skill.
