Destination Tag Routing Techniques Based on a State Model for the IADM Network

A state model is proposed for solving the problem of routing and rerouting messages in the Inverse Augmented Data Manipulator (IADM) network. Using this model, necessary and sufficient conditions for the reroutability of messages are established, and then destination tag schemes are derived. These schemes are simpler, more efficient and require less complex hardware than previously proposed routing schemes. Two destination tag schemes are proposed. For one of the schemes, rerouting is totally transparent to the sender of the message and any blocked link of a given type can be avoided. Compared with previous works that deal with the same type of blockage, the timeXspace complexity is reduced from O(logN) to O(1). For the other scheme, rerouting is possible for any type of link blockage. A universal rerouting algorithm is constructed based on the second scheme, which finds a blockage-free path for any combination of multiple blockages if there exists such a path, and indicates absence of such a path if there exists none. In addition, the state model is used to derive constructively a lower bound on the number of subgraphs which are isomorphic to the Indirect Binary N-Cube network in the IADM network. This knowledge can be used to characterize properties of the IADM networks and for permutation routing in the IADM networks

The Encyclopedia will contain a broad coverage of the field and will include entries on machine organization, programming, algorithms, and applications. The broad coverage, together with extensive pointers to the literature for in-depth study, is expected to make the Encyclopedia a useful reference tool in parallel computing

Industry 4.0 for SMEs

This open access book explores the concept of Industry 4.0, which presents a considerable challenge for the production and service sectors. While digitization initiatives are usually integrated into the central corporate strategy of larger companies, smaller firms often have problems putting Industry 4.0 paradigms into practice. Small and medium-sized enterprises (SMEs) possess neither the human nor financial resources to systematically investigate the potential and risks of introducing Industry 4.0. Addressing this obstacle, the international team of authors focuses on the development of smart manufacturing concepts, logistics solutions and managerial models specifically for SMEs. Aiming to provide methodological frameworks and pilot solutions for SMEs during their digital transformation, this innovative and timely book will be of great use to scholars researching technology management, digitization and small business, as well as practitioners within manufacturing companies

Development of actuated Tangible User Interfaces: new interaction concepts and evaluation methods

Riedenklau E. Development of actuated Tangible User Interfaces: new interaction concepts and evaluation methods. Bielefeld: Universität Bielefeld; 2016.Making information understandable and literally graspable is the main goal of tangible interaction research. By giving digital data physical representations (Tangible User Interface Objects, or TUIOs), they can be used and manipulated like everyday objects with the users’ natural manipulation skills. Such physical interaction is basically of uni-directional kind, directed from the user to the system, limiting the possible interaction patterns. In other words, the system has no means to actively support the physical interaction. Within the frame of tabletop tangible user interfaces, this problem was addressed by the introduction of actuated TUIOs, that are controllable by the system. Within the frame of this thesis, we present the development of our own actuated TUIOs and address multiple interaction concepts we identified as research gaps in literature on actuated Tangible User Interfaces (TUIs). Gestural interaction is a natural means for humans to non-verbally communicate using their hands. TUIs should be able to support gestural interaction, since our hands are already heavily involved in the interaction. This has rarely been investigated in literature. For a tangible social network client application, we investigate two methods for collecting user-defined gestures that our system should be able to interpret for triggering actions. Versatile systems often understand a wide palette of commands. Another approach for triggering actions is the use of menus. We explore the design space of menu metaphors used in TUIs and present our own actuated dial-based approach. Rich interaction modalities may support the understandability of the represented data and make the interaction with them more appealing, but also mean high demands on real-time precessing. We highlight new research directions for integrated feature rich and multi-modal interaction, such as graphical display, sound output, tactile feedback, our actuated menu and automatically maintained relations between actuated TUIOs within a remote collaboration application. We also tackle the introduction of further sophisticated measures for the evaluation of TUIs to provide further evidence to the theories on tangible interaction. We tested our enhanced measures within a comparative study. Since one of the key factors in effective manual interaction is speed, we benchmarked both the human hand’s manipulation speed and compare it with the capabilities of our own implementation of actuated TUIOs and the systems described in literature. After briefly discussing applications that lie beyond the scope of this thesis, we conclude with a collection of design guidelines gathered in the course of this work and integrate them together with our findings into a larger frame

Dancing to an understanding of embodiment

This practice-led research employs choreographic and somatic practices, and their mediation through performance and/or technologies, to facilitate critical engagement and apprehension of notions of embodiment. The core concerns are movement, dance and the body, as sites of knowledge and as modes of inquiry, with particular focus on lived experience approached from a nondualist perspective. Central themes are action, attention, bodyscape, tensegrity, improvisation, interactivity, memory, language and gesture. Taking as a starting point the position that knowledge and mind may be embodied, and that the movement habits and stress markers which pattern bodyscape may in turn inform cognition, the choreographic practice seeks to illuminate, rather than explicate or demonstrate, aspects of embodiment. The methodological approaches are (en)active, heuristic and reflective. Dance, as a exemplar of movement, and choreography, as a mode of creative and critical engagement with dance, are the primary research tools. Somatic approaches to practice, performance and philosophy are investigated for their potential to develop or reveal embodied knowing and awareness. Technological mediation is employed to inform and augment perception and apprehension of the embodied experience of dance, from the perspectives of choreographer, performer and audience. The thesis comprises five dance-based performance works and a written text critically engaging the concepts behind and emergent from this praxis

"Nec tecum nec sine te" : Language-Music Interplays in Musical Responses to Samuel Beckett

Intermediality is rarely a one-way street: Throughout his career, Samuel Beckett employed a variety of modes of expression and media in his works, and – vice versa – it is partly owing to the strong role played by music in his works that Samuel Beckett's works figure so prominently in compositional history from 1930 to the present day. In fact, with more than 250 Beckett-based compositions of different genres and styles and from various countries responding to virtually the entire Beckettian œuvre, Beckett's poems, plays and prose have exerted an influence on composers unequalled by those of any other 20th-century author. This study shows that Beckett's double-coded language, sounds and images have served as a blueprint for crossing medial and social gaps in favor of a de-hierarchization of both the author-audience relationship and the intermedial interplay. As a result of this paradigm shift toward more participatory artistic modes and toward a postmodern "radical pluralization" (Wolfgang Welsch) of meaning and expressive vehicles, Beckett regarded music as an equal interlocutor of language and, vice versa, composers have become more receptive to entirely new modes of text-setting. "Nec tecum nec sine te," a Latin phrase by Ovid cited by Beckett to describe the double-edged relationship between Hamm and Clov from Endgame – interdependent yet noncommittal – equally applies to the text-music interplays portrayed in the present work
