A full solar eclipse is going to be visible from a range of states in the contiguous United States on August 21, 2017. Since the atmosphere of the Earth is charged by the sun, the blocking of the sunlight by the moon may cause short term changes to the atmosphere, such as density and temperature alterations. There are many ways to measure these changes, one of these being ionospheric scintillation. Ionospheric scintillation is rapid amplitude and phase fluctuations of signals passing through the ionosphere caused by electron density irregularities in the ionosphere. At mid-latitudes, scintillation is not as common of an occurrence as it is in equatorial or high-altitude regions. One of the theories that this paper looks into is the possibility of the solar eclipse producing an instability in the ionosphere that will cause the mid-latitude region to experience scintillations that would not normally be present. Instabilities that could produce scintillation are reviewed and altered further to model similar conditions to those that might occur during the solar eclipse. From this, the satellites that are being used are discuses, as is hardware and software tools were developed to record the scintillation measurements. Although this work was accomplished before the eclipse occurred, measurement tools were developed and verified along with generating a model that predicted if the solar eclipse will produce an instability large enough to cause scintillation for high frequency satellite downlinks. / Master of Science

I detta projekt har en arkitektur och användargränssnitt skapats för Tweakers HB. Arkitekturen och designen kommer att användas till ett ord-baserat spel. Det här projektet är en del utav ett ännu större projekt som omfattar en klient-server android applikation. Hela klienten kommer att skapas utifrån arkitekturen som beskrivs i projektet. Användargränssnittdesignen och dess implementation skapar vyn. Arkitekturen har utvecklats med Astah Community Edition och dokumenterats med hjälp av Microsoft Word 2013. Den modell som valdes är MVC mönstret och den har anpassats en del för att vara lämplig just den här applikationen. Designen har arbetats fram med hjälp av Eclipse, Extreme programming och testdriven utveckling. Med hjälp av Eclipse har plugins som är essentiella laddats ned för att skapa användargränssnittet. Själva användargränssnittets design skapades mestadels i Photoshop men också med hjälp av inbyggda verktyg som följde med android sdk tools. Alla krav som ställdes har uppfyllts och är vältestade. Designen blev inte bara uppskattad estetiskt utan praktiskt, detta bekräftades genom att testarna var med på utvecklingen kontinuerligt och gav oss feedback. / This project creates a user interface and architecture for Tweakers HB.

The basic editor is extended with additional specifications on generated EMF model. Those specifications are: constraints on structure and content of bibliographic record written in Check language; Xpand templates for transforming records into cataloguing cards; content assist extensions written in Xtend. Addition functionalities of cataloguing system are also added to basic editor, and those are: showing data about MARC 21 format, entering holdings data, export and import of records, showing cataloguing cards and librarian environment. At the end, RCP technology is used for generating software component for cataloguing that can be used in different library information systems.</p>

近年來越來越多資訊應用領域，開始採用領域特定語言（Domain Specific Language）以表達並解決其領域問題。然而這些特定領域語言多數卻缺乏可大大提升生產力的高品質編輯輔助工具。其主因乃因為從頭開發一套高品質編輯輔助工具所費不貲，然這些特定領域語言普及程度卻遠不如一般通用語言，是以缺乏誘因驅使軟體商開發相關工具。為能快速開發輔助工具，現今的工具開發平台如Eclipse、IDEA，以及NetBeans等，均提供整合開發環境(IDE)的發展支援，以利開發者在平台上快速擴增新語言之編輯環境。即使如此，要發展一套IDE，開發者不僅需深入熟悉所用平台，而且仍需繁瑣與長時間之開發過程。基於此，為求更簡化IDE開發過程，本研究嘗試增強、重構先前開發之雛型系統EGOE【9】，發展出一套遵循模型驅動架構(MDA)之高品質語言編輯環境生成系統：EGOE II。經由此系統的輔助，IDE開發者僅需提供程式語言文法定義(Grammar)及IDE輔助機制客制化資訊，即能套用系統內部的模型轉換程式及程式樣板(Templates)，自動生成以Eclipse為平台的高效能、高品質，且提供豐富編輯輔助的程式語言IDE。 / In recent years more and more fields of applications began to use DSLs(Domain Specific Language) to solve their problems. However, most of these languages were created without accompanying high-quality language specific editors(LSE) to help increase the productivity of the language. The reason for the lack of such tools is mostly economic consideration: because of the very high cost of developing a LSE from scratch, it is not worthwhile to invest a LSE on a less frequently used language. To avoid developing an LSE from scratch, however, most present tool platforms such as Eclipse, IDEA or NetBeans have offered required editor frameworks and APIs to help developers to be able to build LSEs on these platform more quickly and easily. Even so, however, it is still thought hard to develop a LSE by way of platform support since developers need a long and steep learning before they can get adept at a platform and, moreover, the process of developing a LSE remains long, tedious and error-prone. Accordingly, to enable even quicker development of LSEs, we proposed and have developed in this paper a high quality editing environment generating system called EGOE II, which follows the MDA approach and is the refactoring and enhancement of our previous prototype EGOE system. With EGOE II, the developer need only offer an editor-specific specification of the target language, which includes the grammar and editor-related customization informations; he can then apply to it the model translator and program templates provided by the system to automatically produce a high-quality editor on Eclipse platform for the target language.

Depurar sistemas distribuídos continua uma tarefa difícil, mesmo após 30 anos de pesquisa intensa. Embora essa situação possa ser parcialmente atribuída à complexidade das execuções concorrentes, o rápido passo de desenvolvimento das plataformas e tecnologias para computação distribuída também carrega a sua parcela de culpa, por encurtar a vida de muitas ferramentas potencialmente úteis. Neste trabalho, apresentamos uma análise dos principais problemas, técnicas e ferramentas ligados à depuração de sistemas concorrentes e discutidos na literatura. Baseados nessa análise, desenvolvemos e apresentamos uma nova técnica, simples e portátil, que pode ser aplicada a sistemas distribuídos que utilizam chamadas síncronas e bloqueantes. Essa técnica, concebida para sobreviver à heterogeneidade, é validada por meio da implementação de um arcabouço escrito para plataforma Eclipse e instanciado para sistemas de objetos distribuídos baseados em Java/CORBA. / After over thirty years of intense research, debugging distributed systems is still regarded as a difficult task. While this situation could be partially blamed on the fact that concurrent executions are complex, the fast pace of evolution witnessed with distributed computing technologies have also played its by shortening the lifespan of many potentially useful debugging tools. This work presents an analysis of the main issues, techniques and tools in the field of parallel, distributed, and concurrent debugging in general. Based on this analysis, we develop and present a simple and portable technique targeted at synchronous-call-based distributed systems. This technique, designed for portability, is validated through the implementation of an Eclipse-based framework that is instantiated for Java/CORBA distributed object systems.

Of key importance for metamodelling are appropriate modelling formalisms. Most metamodelling languages permit the development of metamodels that specify tree-structured models enriched with semantics like constraints, references and operations, which extend the models to graphs. However, often the semantics of these semantic constructs is not part of the metamodel, i.e., it is unspeci ed. Therefore, we propose to reuse well-known compiler construction techniques to specify metamodel semantics. To be more precise, we present the application of reference attribute grammars (RAGs) for metamodel semantics and analyse commonalities and differences. Our focus is to pave the way for such a combination, by exemplifying why and how the metamodelling and attribute grammar (AG) world can be combined and by investigating a concrete example - the combination of the Eclipse Modelling Framework (EMF) and JastAdd, an AG evaluator generator.
