Study on Signal Detection and Recovery Methods with Joint Sparsity (Springer Theses)
by Xueqian WangThe task of signal detection is deciding whether signals of interest exist by using their observed data. Furthermore, signals are reconstructed or their key parameters are estimated from the observations in the task of signal recovery. Sparsity is a natural characteristic of most of signals in practice. The fact that multiple sparse signals share the common locations of dominant coefficients is called by joint sparsity. In the context of signal processing, joint sparsity model results in higher performance of signal detection and recovery. This book focuses on the task of detecting and reconstructing signals with joint sparsity. The main contents include key methods for detection of joint sparse signals and their corresponding theoretical performance analysis, and methods for joint sparse signal recovery and their application in the context of radar imaging.

Studying Virtual Math Teams
by Gerry StahlStudying Virtual Math Teams centers on detailed empirical studies of how students in small online groups make sense of math issues and how they solve problems by making meaning together. These studies are woven together with materials that describe the online environment and pedagogical orientation, as well as reflections on the theoretical implications of the findings in the studies. The nature of group cognition and shared meaning making in collaborative learning is a foundational research issue in CSCL. More generally, the theme of sense making is a central topic in information science. While many authors allude to these topics, few have provided this kind of detailed analysis of the mechanisms of intersubjective meaning making. This book presents a coherent research agenda that has been pursued by the author and his research group. The book opens with descriptions of the project and its methodology, as well as situating this research in the past and present context of the CSCL research field. The core research team then presents five concrete analyses of group interactions in different phases of the Virtual Math Teams research project. These chapters are followed by several studies by international collaborators, discussing the group discourse, the software affordances and alternative representations of the interaction, all using data from the VMT project. The concluding chapters address implications for the theory of group cognition and for the methodology of the learning sciences. In addition to substantial introductory and concluding chapters, this important new book includes analyses based upon the author's previous research, thereby providing smooth continuity and an engaging flow that follows the progression of the research. The VMT project has dual goals: (a) to provide a source of experience and data for practical and theoretical explorations of group knowledge building and (b) to develop an effective online environment and educational service for collaborative learning of mathematics. Studying Virtual Math Teams reflects these twin orientations, reviewing the intertwined aims and development of a rigorous science of small-group cognition and a Web 2.0 educational math service. It documents the kinds of interactional methods that small groups use to explore math issues and provides a glimpse into the potential of online interaction to promote productive math discourse.

Störungstolerante Datenauthentifizierung für drahtlose Kommunikation
by Obaid Ur-Rehman Natasa ZivicDieses Buch gibt einen Einblick in die Herausforderungen der Datenauthentifizierung über drahtlose Kommunikationskanäle. Die Autoren gehen davon aus, dass die etablierten Standard-Authentifizierungsmechanismen nicht ausreichen, um Daten wie Sprache, Bilder und Videos über drahtlose Kanäle zu authentifizieren, da die drahtlose Kommunikation durch zahlreiche Störungen gekennzeichnet ist. Die Autoren schlagen neue Mechanismen vor, die auf so genannten Soft-Authentifizierungsalgorithmen basieren, die einige Änderungen an den zu schützenden Daten tolerieren. Die Autoren erklären, dass das Ziel dieser Algorithmen darin besteht, tolerant gegenüber inhaltlichen Änderungen auf Grund von Übertragungsfehler zu sein, aber dennoch in der Lage zu sein, Fälschungen zu erkennen. Ein weiterer Vorteil der Soft-Authentifizierungsalgorithmen besteht darin, dass sie in der Lage sind, die veränderten Stellen zu identifizieren und sie nach Möglichkeit zu korrigieren. Die Autoren zeigen, wie man dies erreicht, indem man die Datenmerkmale mit Hilfe von fehlerkorrigierenden Codes schützt. · Erörtert Methoden zur Authentifizierung von Daten (insbesondere von Bildern) bei Übertragungsstörungen, die bei der drahtlosen Kommunikation auftreten; · Stellt eine neue Klasse von Soft-Authentifizierungsmethoden vor, die anstelle der üblichen Hard-Authentifizierungsmethoden verwendet werden, um geringfügige Änderungen der Bilddaten zu tolerieren; · Verfügt über Authentifizierungsmethoden, die auf der Verwendung von Authentifizierungscodes und digitalen Wasserzeichen basieren
