Adaptive Identification of Acoustic Multichannel Systems Using Sparse Representations (T-Labs Series in Telecommunication Services)
by Karim HelwaniThis book treats the topic of extending the adaptive filtering theory in the context of massive multichannel systems by taking into account a priori knowledge of the underlying system or signal. The starting point is exploiting the sparseness in acoustic multichannel system in order to solve the non-uniqueness problem with an efficient algorithm for adaptive filtering that does not require any modification of the loudspeaker signals.The book discusses in detail the derivation of general sparse representations of acoustic MIMO systems in signal or system dependent transform domains. Efficient adaptive filtering algorithms in the transform domains are presented and the relation between the signal- and the system-based sparse representations is emphasized. Furthermore, the book presents a novel approach to spatially preprocess the loudspeaker signals in a full-duplex communication system. The idea of the preprocessing is to prevent the echoes from being captured by the microphone array in order to support the AEC system. The preprocessing stage is given as an exemplarily application of a novel unified framework for the synthesis of sound figures. Finally, a multichannel system for the acoustic echo suppression is presented that can be used as a postprocessing stage for removing residual echoes. As first of its kind, it extracts the near-end signal from the microphone signal with a distortionless constraint and without requiring a double-talk detector.

Adaptions of Western Literature in Meiji Japan
by J. MillerThis book examines three examples of late nineteenth-century Japanese adaptations of Western literature: a biography of U.S. Grant recasting him as a Japanese warrior, a Victorian novel reset as oral performance, and an American melodrama redone as a serialized novel promoting the reform of Japanese theater. Written from a comparative perspective, it argues that adaptation (hon'an) was a valid form of contemporary Japanese translation that fostered creative appropriation across many genres and among a diverse group of writers and artists. In addition, it invites readers to reconsider adaptation in the context of translation theory.
Adapting Translation for the Stage (Routledge Advances in Theatre & Performance Studies)
by Geraldine Brodie Emma ColeTranslating for performance is a difficult – and hotly contested – activity. Adapting Translation for the Stage presents a sustained dialogue between scholars, actors, directors, writers, and those working across these boundaries, exploring common themes and issues encountered when writing, staging, and researching translated works. It is organised into four parts, each reflecting on a theatrical genre where translation is regularly practised: The Role of Translation in Rewriting Naturalist Theatre Adapting Classical Drama at the Turn of the Twenty-First Century Translocating Political Activism in Contemporary Theatre Modernist Narratives of Translation in Performance A range of case studies from the National Theatre’s Medea to The Gate Theatre’s Dances of Death and Emily Mann’s The House of Bernarda Alba shed new light on the creative processes inherent in translating for the theatre, destabilising the literal/performable binary to suggest that adaptation and translation can – and do – coexist on stage. Chronicling the many possible intersections between translation theory and practice, Adapting Translation for the Stage offers a unique exploration of the processes of translating, adapting, and relocating work for the theatre.

Adapting Interactive Learning Environments to Student Competences: The Case for Complex Dynamic Systems (SpringerBriefs in Educational Communications and Technology)
by Aklilu Tilahun Tadesse Pål Ingebright Davidsen Erling MoxnesThis monograph focuses on the design of personalized and adaptive online interactive learning environment (OILE) to enhance students’ learning in and about complex dynamic systems (CDS). Numerous studies show that students experience difficulties when learning in and about CDS. The difficulties are due to challenges originating from a) the structural complexity of CDS, (b) the production of dynamic behavior from the underlying systems structure, and (c) methods, techniques and tools employed in the analysis of such systems. Despite the fact that studies have uncovered such learning challenges, it is still not well understood how we may effectively address these challenges. In this monograph, the authors provide some answers as to how we may best improve our cognitive capabilities to meet these challenges by way of effective instructional methods, techniques, and tools and their implementation in the form of an OILE. The OILE developed for this purpose, builds on a five-step holistic instructional design framework; identification of instructional design models, identification of authentic learning material, identification of instructional methods, identification of instructional techniques, and design of the interface and implementation of the tool. In this OILE development, six well-documented instructional design models were considered; a four component instructional design, first principles of instruction, constructivists learning environment, task centered instruction, cognitive apprenticeship, and elaboration theory.
Adaptation Considered as a Collaborative Art: Process and Practice (Adaptation in Theatre and Performance)
by Bernadette Cronin Rachel MagShamhráin Nikolai PreuschoffThis book examines the processes of adaptation across a number of intriguing case studies and media. Turning its attention from the 'what' to the 'how' of adaptation, it serves to re-situate the discourse of adaptation studies, moving away from the hypotheses that used to haunt it, such as fidelity, to questions of how texts, authors and other creative practitioners (always understood as a plurality) engage in dialogue with one another across cultures, media, languages, genders and time itself. With fifteen chapters across fields including fine art and theory, drama and theatre, and television, this interdisciplinary volume considers adaptation across the creative and performance arts, with a single focus on the collaborative.
Ad Hoc Networks Telecommunications and Game Theory
by Malek Benslama Mohamed Lamine Boucenna Hadj BatatiaRandom SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks. The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the saturation zone. In this context, game theory has demonstrated his ability to lead the network to a more efficient equilibrium. This, we were led to propose our model code set that formalizes the behavior of nodes during transmission within SALOHA networks and CSMA respectively.

Ad Hoc Networks: Second International Conference, ADHOCNETS 2010, Victoria, BC, Canada, August 18-20, 2010, Revised Selected Papers (Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering #49)
by Victor Cm Leung Jun Zhi-Zhong David Simplot-RylAd hoc networks, which include a variety of autonomous networks for specific purposes, promise a broad range of civilian, commercial, and military applications. These networks were originally envisioned as collections of autonomous mobile or stationary nodes that dynamically auto-configure themselves into a wireless network without relying on any existing network infrastructure or centralized administration. With the significant advances in the last decade, the concept of ad hoc networks now covers an even broader scope, referring to the many types of autonomous wireless networks designed and deployed for a specific task or function, such as wireless sensor networks, vehicular networks, home networks, and so on. In contrast to the traditional wireless networking paradigm, such networks are all characterized by sporadic connections, highly error-prone communications, distributed autonomous operation, and fragile multi-hop relay paths. The new wireless networking paradigm necessitates reexamination of many established concepts and protocols, and calls for developing a new understanding of fundamental problems such as interference, mobility, connectivity, capacity, and security, among others. While it is essential to advance theoretical research on fundamental and practical research on efficient policies, algorithms and protocols, it is also critical to develop useful applications, experimental prototypes, and real-world deployments to achieve an immediate impact on society for the success of this wireless networking paradigm.

Ad Hoc Networks: A Statistical Perspective
by Jyoti Prakash Singh Paramartha Dutta Amlan ChakrabartiThis book identifies the time-dependent network parameters: neighbour count, link load, path length, cluster count and delay, and presents a first-of-its-kind discussion on temporal parameters in mobile ad hoc networks. Frequent topology changes and multiple link failures occur in mobile ad hoc network due to arbitrary and random movement of nodes. This dynamic environment challenges the delivery of data and makes it essential to find better models for network parameters that are shifting with time. The parameters identified are put into the framework of time series because of their temporal characteristic, and when they are modelled using time series framework they exhibit a sound fit with Autoregressive AR(p) models of order p. The order p is evaluated for each fitted model and found to lie between one and three. The book also analyses the dependence of end-to-end delay of ad hoc network on various external factors such as the number of nodes, routing protocol, mobility models and path length and develops two prediction models. The book will be useful for researchers and professionals alike.
