Access Control and Service-Oriented Architectures.

Access Control and Service-Oriented Architectures" investigates in which way logical access control can be achieved effectively, in particular in highly dynamic environments such as service-oriented architectures (SOA's). The author combines state-of-the-art best-practice and projects these onto the SOA. In doing so, he identifies strengths of current approaches, but also pinpoints weaknesses. These weaknesses are subsequently mitigated by introducing an innovative new framework called EFSOC. The framework is validated empirically and preliminary implementations are discussed.

A design representation model for high-level synthesis

Design tools share and exchange various types of information pertaining to the design. The identification of a uniform design representation to capture this information is essential for the development of a successful design environment. We have done an extensive study on the representation needs of existing database tools in the UCI CADLAB; examples of which are graph compilers for high-level hardware specifications, state schedulers, hardware allocators, and microarchitecture optimizers. The result of this study is the development of a design representation model that will serve as a common internal representation (DDM) for all system and behavioral synthesis tools. DDM thus builds the foundation for a CAD Framework in which design tools can communicate via operating on this common representation. The design information is composed of three separate graph models: the conceptual model, the behavioral model and the structural model. The conceptual model (represented by a Design Entity Graph) captures the overall organization of the design information, such as, versions and configurations. The behavioral model (represented by an Augmented Control/Data Flow Graph) describes the design behavior. The structural model (represented by an Annotated Component Graph) captures the hierarchical data path structure and its geometric information. In this paper, we define the last two graph models. They both capture the actual design data of the application domain. Since VHDL has gained increasing popularity as hardware description language for synthesis, we give numerous examples throughout this report that show how the proposed design representation model can be used to represent VHDL specifications

Metacognitive Writing Strategies for Emerging Dancer-Scholars: Uncovering Supportive Links Between Academic Writing and Choreographic Processes

Canadian graduate programs in Dance at the Masters level frequently accept students with long professional careers in dance but limited academic background in writing essays. Writing term papers, with perhaps only dim memories of high school writing instruction to draw from, can pose challenging experiences for such emerging dancer-scholars. While long standing metacognitive reading strategies are commonly available to assist those new to graduate studies with interpreting their academic readings, no comparable metacognitive writing strategies appear in the literature to support an academic writing process. However, metacognition theory regarding the role of affect in monitoring and controlling ones progress through the completion of a task offers potential applications to support academic writing. Furthermore, re-imagining academic writing as an experience deeply informed by affect resonates with recent research into articulating the affective or felt sense understanding of ones creative processes in composing a choreographic work. Investigating connections between how dancers process composition tasks in the two disciplines revealed metacognitive processing parallels. The findings implied several considerations for designing a writing pedagogy specific to the needs of emerging dancer-scholars. This dissertation research with graduate dance students in Canada and the US incorporated ethnographic and educational action research approaches for identifying, addressing and documenting participants perceived essay writing problems. Initial group workshops prepared the participants for individual Case Study research sessions, which were characterized by practice-led research/research-led practice methods of generating, developing, performing and theorizing. The research investigated the howness of each participants writing process across a series of analytical writing assignments. Participants and I collaborated in uncovering the focus and potential structure for each paper using visual-spatial-dialoguing techniques. Participants expressed affective experiences during these video- or audio-taped sessions and in emailed reflections. Their gestural and verbal metaphors generated metacognitive knowledge about the source of writing frustrations versus the support provided by using familiar processing techniques from their choreographic practices. Their retrospective analyses demonstrated the participants metacognitive evolution from personal awareness to co- and self-regulated learning about the characteristic processing traits underlying their writing and choreographic practices. A comparative analysis of three Case Studies suggested metacognitive writing strategies for supporting emerging dancer-scholars

A CLUSTER ANALYSIS OF SOCIAL MEDIA USE IN THE ANGLOPHONE CRISIS IN CAMEROON: A CASE STUDY OF FACEBOOK POSTS.

This thesis applies a method of rhetorical criticism – cluster analysis – to explore the different narratives on and about the Anglophone crisis in Cameroon by two prominent rhetors involved in the crisis. The artifacts in the study were Facebook posts published by Cameroon’s president, Paul Biya, and a prominent Anglophone activist, Mark Bareta. The thesis set out to answer two research questions. The first question focused on the descriptive narratives that emerge from the rhetors in the crisis; the second question focused on the rhetors’ motives. The different narratives that emerged showed that Cameroon’s president pushed the narratives of “national unity” and “peace”, indicating his intentions to persuade Cameroonians, particularly those in the two English speaking regions of the country, to focus on a united country. On the other hand, the prominent Anglophone activist focused his rhetoric on the narrative of secession, aligning his narrative with his intention to have Anglophone Cameroon to secede. The narratives and motives emerged from examining key terms (god terms and devil terms) plus the terms that cluster around the god terms and devil terms respectively. Trends significant to this research, recommendations on resolving the anglophone crisis, limitations of the study, and direction for further research are discussed. This thesis has contributed to rhetorical theory by applying cluster analysis as method of rhetorical criticism to social media posts (a novel area in the method’s application)

Integrated testing and verification system for research flight software design document

The NASA Langley Research Center is developing the MUST (Multipurpose User-oriented Software Technology) program to cut the cost of producing research flight software through a system of software support tools. The HAL/S language is the primary subject of the design. Boeing Computer Services Company (BCS) has designed an integrated verification and testing capability as part of MUST. Documentation, verification and test options are provided with special attention on real time, multiprocessing issues. The needs of the entire software production cycle have been considered, with effective management and reduced lifecycle costs as foremost goals. Capabilities have been included in the design for static detection of data flow anomalies involving communicating concurrent processes. Some types of ill formed process synchronization and deadlock also are detected statically

Cartographies of Copyright: Crisis & Propertization

Cartographies of Copyright is a cultural history of copyright that maps out various contradictions and tensions that give shape to the crisis of copyright and its relations to US music industries. More specifically, this work charts the radical dissension of copyright in recent history and argues for an understanding of the crisis as an internal transformative process. This formulation shifts the analytic approach from an abstract conceptual-legal perspective to a series of discrete points within a lived history, culture and materiality of copyright thought, audio technologies and neoliberal capitalism. Seen in terms of territorialization, the expansion of copyright via the music industries gives unique insight into the particular ways music and its media formats effect the evolution of copyright culture and law. When framed this way, an investigation into music and copyright leads to recognizing new forms of control, changing modes of administering access and contemporary relations of power. To chart the effects of these transformations I draw upon the tensions and problematics that constitute the Wu-Tang Clan’s 2015 one-of-a-kind release: Once Upon A Time In Shaolin. After accessing contentious foci within traditional copyright paradigms, I argue that classical models lack explanatory power, pose problems for understanding the transformations of copyright throughout history and fail to provide a comprehensive account of the present crisis. Taking inspiration from the reoccupation thesis presented by Hans Blumenberg and recent research in copyright I propose an alternative model rooted at the dialectic crux of property metaphors, audio technologies and formats, and neocapitalist commodity logic––all of which give shape to an internal transformation within copyright law and culture I term propertization. Cartographies of Copyright is not a legal treatise, per se; rather, the work sees law as text set within a larger social milieu liable to change and evolution. Drawing from legal theory, cultural studies and media studies the work engages copyright from the perspectives of critical history, rhetoric, media-materiality and speculative economics. The multidisciplinary approach also stakes out new formations to the problematics faced by music historically and to draw connections between the music industries and the broader social contexts they are situated in. Cartographies argues for a new lexicon to begin imagining alternative models to account for copyright’s transformations––ones better suited to imagining viable alternatives. It calls attention to the urgent need of public discussion concerning the role of copyright in contemporary music and culture and provides modest suggestions for thinkingSiirretty Doriast

Recommendation Framework Based on Subjective Logic in Decision Support Systems

In this thesis our goals are to investigate the suitability of subjective logic within the decision support context that requires connectivity to complex data, user specification of frames of discernment, representation of complex reasoning expressions, an architecture that supports distributed usage of a decision support tool based on a client-server approach that separates user interactions on the browser side from computational engines for calculations on the server side, and analysis of the suitability and limitations of the proposed architecture
