Detta arbete har genom experiment och tester undersökt förbättringspotentialen för en halvautomatisk grundtillsyn av Ra180. Eftersom att denna grundtillsyn tar lång tid är det högst relevant att försöka korta ner den. Genom noggranna mätningar som har testats har det tagits fram lämpliga lösningar för en påtaglig förbättring. I linje med detta har även en undersökning gjorts av huruvida en helautomatisk grundtillsyn är möjlig. Genom dessa undersökningar har också en hårdvaruprototyp till denna metod tagits fram och implementerats.

Neste trabalho apresentamos uma investigação desenvolvida ao longo do ano de 2009 em uma disciplina de Física Básica de Eletromagnetismo da Universidade Federal do Rio Grande do Sul (UFRGS). O objetivo foi analisar as visões de mundo e a relação dos estudantes com o relatório tradicional e com o laboratório de ensino. Dentro desta estratégia de pesquisa foi utilizado o Vê de Gowin, um instrumento heurístico muito utilizado para explicitar o processo de produção do conhecimento. Nesse contexto ele foi utilizado em contraposição ao relatório tradicional. Entendemos por relatório tradicional aquele que os alunos já estão acostumados a realizar em semestres anteriores. A teoria da aprendizagem significativa de David Ausubel foi utilizada para avaliar os roteiros já disponíveis para as atividades experimentais. Ainda nessa perspectiva, vimos a estreita relação que a teoria educativa de Gowin tem com a teoria da aprendizagem significativa, o que nos possibilitou uma visão ainda mais aprimorada dos roteiros. Destacamos que para avaliar a relação dos estudantes com as atividades experimentais, utilizamos como referencial epistemológico a contribuição de Thomas Khun. Os resultados mostram que os alunos possuem boa aceitação ao novo método de avaliação, que também conseguiu explorar de forma mais objetiva os aspectos essenciais à formação do futuro físico no que se refere ao papel da atividade experimental. Contudo, vemos que o aproveitamento dos alunos permanece constante frente à mudança avaliativa. Isto significa que a introdução do Vê não prejudica o desempenho dos alunos. Por fim, especulamos que características próprias de nossa comunidade são refletidas pelos alunos nos relatórios. / This dissertation presents a research carried out during 2009, in the discipline of Electromagnetism at introductory college level, at the Federal University of Rio Grande do Sul (UFRGS), Brazil. It aimed at analyzing the students’ worldviews and their reaction to the standard lab report model and to the lab classes. Within this research strategy, Gowin’s Vee, which is a heuristic instrument that can make explicit the knowledge production process, was used. In this context, this instrument was utilized as a counterpoint to the traditional lab report model. In our view, this traditional report is the one students are familiar with, since they have already made reports in previous semesters. Ausubel’s meaningful learning theory was used to evaluate the available guides for experimental activities. Under this perspective , we verified the close relationship that exists between Gowin’s educating theory and Ausubel’s meaningful learning theory, and this has provided us with a more refined view of such guides for experimental activities. We emphasize that, in order to evaluate the students’ relation with the experimental activities, we applied Kuhn’s contributions as part of the theoretical framework of this research. Findings indicate that students seem to react positively to the new evaluation method, and, moreover, that they seemed to explore in a more objective way the essential aspects related to the formation of the future physicist, in what concerns the role of experimental activity. Nevertheless, it was possible to notice that students’ performance remained constant in regard to this evaluative change. This might mean that the introduction of the Vee does not hinder students’ performance. Finally, it was explored to which extent the community’s main features were reflected on the students’ reports.

The aim of my diploma thesis was programming of systems for measuring AC, DC and impedance measurements. Each measuring system measures selected characteristics of current amplifier with controllable amplification DACA_N. Control programs I have created in Agilent VEE Pro 9.2. The measured data are stored to executable files in MS Excel for further processing. With created measurement programs I made measurements of eight current amplifiers. The results of individual measurements I compiled into graphs and compared with each other circuit characteristics of amplifiers. Then there is described controlling and connection of current amplifier and its construction. At the end the diploma thesis describes amplifiers with the worst and the best measured circuit characteristics. The measured values show that the amplifier DACA_N with slight differences works by theoretical assumptions and measurement systems suggested by me work with no problem.

The last part contains the technical and economic evaluation, from which results that, technically and economically, the new production technology is preferable to the existing technology.

自2007年國家通訊傳播委員會（NCC）發放六張無線寬頻接取執照（Wireless Broadband Access, WBA）後，至今台灣六家WiMAX營運商已全數開台，台灣WiMAX產業正式進入商轉營運階段。然而由於WiMAX為一新興產業，產業之遊戲規則仍待確立，加上其他4G等行動上網技術的競爭下，各家WiMAX營運商之背景與資源分部情形無法立即分出競爭勝負，還需端看營運商如何對自身資源作出適當的評估與利用，以發展合適之競爭策略，才能達到產業競爭優勢。 因此本研究從資源基礎理論的角度出發，透過個案研究法，以得到南區執照的威達雲端電訊進行研究，了解威達雲端在發展WiMAX產業上，對資源的運用。本研究擬探討之四個問題為：(1) 威達雲端電訊當初選擇進入WiMAX產業的評估與原因為何？ (2) 威達雲端電訊在發展WiMAX上的核心資源與資源缺口各為何？(3) 威達運端電訊在進入WiMAX此一新興產業時，如何針對本身資源的優劣勢發展出適當的競爭策略？(4) 威達雲端電訊相較於其他WiMAX營運商，有何競爭優勢？(5) LTE與WiMAX陣營在未來發展上各有何資源優勢，WiMAX營運商該如何面對LTE的挑戰？ 研究結果發現：(1) 威達雲端最大核心資源優勢為本身擁有大量內容及相關經驗、基礎顧客群，與光纖網路之布建。(2) 威達雲端主要資源缺口為資金、相關人才與電信發 展經驗與技術。(3) 威達雲端有效利用具延展性之資源，將資源做延伸與強化，進行多角化發展，推出新產品組合及服務，以達到綜效與擴大整體經濟規模。(4) 威達雲端進行策略聯盟等合作方式進行資源之補足，尤其是以吸取電信相關布建經驗與技術為主。(5) 相較於其他相關業者，威達雲端以較低成本提供WiMAX服務，並將WiMAX技術與其他資源結合，推出差異化之服務為其競爭之優勢。 / Since the National Communications Commission released six operating licenses of Wireless Broadband Access (WBA) in 2007, the six WiMAX operators in Taiwan have all completed deployment for commercial services by the end of 2010. However, as an emerging industry, WiMAX technology and its industry have not fully matured. Meanwhile, WiMAX is facing the rival fourth generation wireless technology . Under the circumstance, in order to create competitive advantages, WiMAX operators should lie primarily in the application of the bundle of valuable resources at the firm's disposal. Therefore, this paper, takes the Resource-Based Theory as the analysis structure, with reference to the case of licensed WiMAX operator “Vee Telecom Multimedia Co,” (or simply Vee) attempts to find out how the operator utilizes its core resource to carry out the competitive strategy. The purposes of this thesis include: (1) The reason why Vee chose to enter WiMAX industry; (2) The core resources and recourse gaps of Vee; (3) When entering the WiMAX industry, how Vee carry out the strategic deployment of its resources; (4) Compare to other WiMAX operators, what competitive advantages does Vee have; (5) What core resources do WiMAX and LTE operators have? How do WiMAX operators face the challenge of LTE technology? The results showed that (1) the core resources of Vee are contents, customer base, and the fiber network. (2) the resource gaps of Vee are funds, talent, experiences in telecommunications. (3) with the effective use of scalable resources, Vee extends and strengthens the resources to develop new products and services portfolio, in order to achieve synergies and increase economies of scale. (4) using strategic alliances and other cooperative approach to fill the resource gaps, especially the deployment experiences in telecommunications. (5) compared to other operators, Vee provides WiMAX services at a lower cost and offers differentiated services to gain its competitive advantage.
