>Magister Scientiae - MSc / The growing size of raw data and the lack of internet communication technology to keep up with that growth is introducing unique challenges to academic researchers. This is especially true for those residing in rural areas or countries with sub-par telecommunication infrastructure. In this project I investigate the usefulness of cloud computing technology, data analysis workflow languages and portable computation for institutions that generate data. I introduce the concept of a software solution that could be used to simplify the way that researchers execute their analysis on data sets at remote sources, rather than having to move the data. The scope of this project involved conceptualising and designing a software system to simplify the use of a cloud environment as well as implementing a working prototype of said software for the OpenStack cloud computing platform. I conclude that it is possible to improve the performance of research pipelines by removing the need for researchers to have operating system or cloud computing knowledge and that utilising technologies such as this can ease the burden of moving data.

<p[>The Military Tactical Network (MTN) system is an automated satellite communications system designed to provide a near term tactical intelligence dissemination capability to deployed forces. The system was initially developed to address the pressing need for the timely delivery of intelligence information. The primary customers of the MTN system are the Office of the Secretary of Defense for Command, Contro, Communications and Intelligence (C31) and the intelligence community. The user community will include members of these two organizations as well as military personnel.</p> <p>The MTN system was used during a recent military demonstration and it was determined that the MTN Gateway Interface, the mechanism available to users for injecting messages for delivery into the system and for performing additional administrative :functions, needs to be redesigned prior to the system achieving Initial Operating Capability (IOC). The system currently uses a cryptic, menu-driven interface with an all ASCII representation. This project and report addresses the need for an improved Gateway Interface for the MTN System The systems engineering approach is followed in presenting the conceptual and preliminary design of the MTN Gateway Interface. The development of the improved interface will enhance the capabilities and usability of the MTN system.</p> / Master of Science

A software system, once deployed into its target environment, might need to be modified for various reasons. The reasons might be specific to that software system, such as failures, or, more general, such as changes in the environment in which the software system is embedded. Depending on the reason, a modification might obviously not only be restricted to a particular software system. It might also concern other existing software systems and particularly also software systems under development. The modification of a software system under development is merely a problem of modifying its development process, also called software process. Such modifications generally cannot be automatically carried out by autonomous process support systems due to the complexity inherent in software processes and in the necessary modifications. It usually needs to be guided by a human process manager. A process support system can, however, offer the human process manager certain services to assist in modifying a software process. One of these services is that of decision support.

Ce document retrace mes activités de recherche depuis ma thèse soutenue en juillet 1997. Certains des travaux présentés sont achevés, d'autres sont en cours ou encore dans un stade exploratoire. De 1993 à 1999, je me suis intéressé aux différents aspects du <br />partitionnement logiciel/matériel dans la conception de systèmes intégrés numériques de télécommunications. Depuis 1999, mes travaux ont porté sur la conception de systèmes multiprocesseurs monopuces, et plus particulièrement sur ce qui a trait aux relations entre <br />logiciel et matériel. Ces systèmes sont généralement dédiés à une application ou à une classe d'applications, ce qui permet d'optimiser l'architecture et les programmes. Mes recherches ses sont donc <br />focalisées sur l'architecture mémoire, les interfaces de <br />communication entre composants et le prototypage. Pour ces trois axes de recherche, des méthodes et des outils d'aide à la conception ont été définis et développés. Des travaux toujours en cours portent sur la généralisation d'une méthode de conception de composants d'interface matériels à partir <br />d'une spécification sous forme de services requis et fournis. Une telle spécification est déjà utilisée pour représenter des protocoles dans les réseaux de communication et pour le développement<br />des couches logicielles de communication. Son extension à la conception des interfaces matérielles homogénéiserait les langages, méthodes et outils de l'environnement de conception. Mes travaux futurs s'orientent vers deux axes : l'intégration <br />logiciel/matériel et l'adéquation entre architecture et système d'exploitation. Dans les deux cas, les relations étroites entre les ressources physiques de l'architecture et les couches logicielles qui y accèdent doivent permettre d'améliorer sensiblement les performances.

A frustrating aspect of the frequent changes to large VLSI CAD systems is that so little of the old available programs can be reused. It takes too much time and effort to find the reusable pieces and recast them for the new use. Our thesis is that such systems can be designed for reusability by designing the software as layers of problem oriented languages, which are implemented by suitably extending a "base" language. We illustrate this methodology with respect to VLSI CAD programs and a particular language layer: a language for handling networks. We present two different implementations. The first uses UNIX and Enhanced C. The second approach uses Common Lisp on a Lisp machine.

The purpose of this study was to examine the effect of Scholastic, Incorporated's ReadAbout software system on student achievement in the subject of reading. The study assessed the relationship between the amount of time third and fourth grade students spent utilizing the program and their scale scores on the Texas Assessment of Knowledge and Skills (TAKS) reading test, as reported in student records of third and fourth graders at Comal Independent School District, Texas. Additionally, the study attempted to determine possible differences among students for the variables of gender, primary language of learning, and socio-economic status, as reported in student records of third and fourth graders at Comal Independent School District, Texas. For the purpose of this study, school and student performance analysis included only the nine elementary schools in the Comal Independent School District that served third and fourth grade students during the 2007-2008 school year. The student population under study consisted of a total of 585 third graders and 792 fourth graders (1377 total students). The research findings of this study include the following: 1. There was a statistically significant relationship between the amount of time that both third grade and fourth grade students spent using the ReadAbout software system and their performance on the third and fourth grade TAKS reading tests. 2. No statistically significant relationships were determined for gender or socioeconomic status when the amount of time individuals in each subpopulation spent using ReadAbout and the students' TAKS reading test scale scores were compared. However, in the analysis for primary language of learning, a small group of Spanish-speaking students who used ReadAbout for more than 16.5 hours prior to taking the test outperformed their English-speaking peers in the same usage category, and this difference did prove to be statistically significant.

As software evolves and becomes more complex, self-adaptive systems become a moreinteresting solution. Self-adaptive software systems are capable to perform changes inthemselves without human intervention. To make this possible it is necessary toperform a good observation of the system and its environment. This observation is madeby a monitoring system.In this paper, a framework for monitoring OSGi based applications is presented.OSGi is a module system and service platform for Java. This framework offers run-timeinformation about OSGi modules, services and their behavior.The first step is to make a state-of-the-art survey of existing methods to monitor inthe field of self-adaptive systems and OSGi based applications. The survey reviews aset of articles in the area. It is performed to discover what are the common objectivesand problems that any monitoring system faces. After that, the requirements for theframework are stated. These requirements specify the functionality that the frameworkis required to provide, along with the quality attributes that it has to meet. Todemonstrate use of the contributed monitoring framework, we have developed twoexample demonstrators. The objective of these demonstrators is to provide users of theframework with working examples, so that they can use the framework to develop theirown monitoring systems.
