Web 2.0 technologies, open source software platforms, and mobile applications have transformed teaching and learning of second and foreign languages. Language teaching has transitioned from a teacher-centered approach to a student-centered approach through the use of Computer-Assisted Language Learning (CALL) and new teaching approaches. Engaging Language Learners through Technology Integration: Theory, Applications, and Outcomes provides empirical studies on theoretical issues and outcomes in regards to the integration of innovative technology into language teaching and learning. This reference wok discusses empirical findings and innovative research using software and applications that engage learners and promote successful learning, essential tools for educational researchers, instructional technologists, K-20 language teachers, faculty in higher education, curriculum specialists, and researchers.
In 1775, Paul Revere, the folk hero of the American Revolution, galloped wildly on horseback through small towns to warn American colonists that the British were coming. In today's Internet age, how do we warn vast numbers of computers about impending cyber attacks? Rapid and widespread dissemination of security updates throughout the Internet would be invaluable for many purposes, including sending early-warning signals, distributing new virus signatures, updating certificate revocation lists, dispatching event information for intrusion detection systems, etc. However, notifying a large number of machines securely, quickly, and with high assurance is very challenging. Such a system must compete with the propagation of threats, handle complexities in large-scale environments, address interruption attacks toward dissemination, and also secure itself. Disseminating Security Updates at Internet Scale describes a new system, "Revere," that addresses these problems. "Revere" builds large-scale, self-organizing and resilient overlay networks on top of the Internet to push security updates from dissemination centers to individual nodes. "Revere" also sets up repository servers for individual nodes to pull missed security updates. This book further discusses how to protect this push-and-pull dissemination procedure and how to secure "Revere" overlay networks, considering possible attacks and countermeasures. Disseminating Security Updates at Internet Scale presents experimental measurements of a prototype implementation of "Revere" gathered using a large-scale oriented approach. These measurements suggest that "Revere" can deliver security updates at the required scale, speed and resiliency for a reasonable cost. Disseminating Security Updates at Internet Scale is designed to meet the needs of researchers and practitioners in industry and graduate students in computer science. This book will also be helpful to those trying to design peer systems at large scale when security is a concern, since many of the issues faced by these designs are also faced by "Revere." The "Revere" solutions may not always be appropriate for other peer systems with very different goals, but the analysis of the problems and possible solutions discussed here will be helpful in designing a customized approach for such systems.

With a focus on developing computational algorithms for examining waveform design in diverse active sensing applications, this guide is ideal for researchers and practitioners in the field. The three parts conveniently correspond to the three categories of desirable waveform properties: good aperiodic correlations, good periodic correlations and beampattern matching. The book features various application examples of using the newly designed waveforms, including radar imaging, channel estimation for communications, an ultrasound system for breast cancer treatment and covert underwater communications. In addition to numerical results, the authors present theoretical analyses describing lower bounds or limitations of performance. Focusing on formulating practical problems mathematically and solving the mathematical problems using efficient and effective optimization techniques, the text pays particular attention to developing easy-to-use computational approaches. Most algorithms are accompanied by a table clearly detailing iteration steps and corresponding MATLAB codes are available on the companion website.

MathematicsMechanization consistsoftheory, softwareandapplicationofc- puterized mathematical activities such as computing, reasoning and discovering. ItsuniquefeaturecanbesuccinctlydescribedasAAA(Algebraization, Algori- mization, Application). The name Mathematics Mechanization has its origin in the work of Hao Wang (1960s), one of the pioneers in using computers to do research in mathematics, particularly in automated theorem proving. Since the 1970s, this research direction has been actively pursued and extensively dev- oped by Prof. Wen-tsun Wu and his followers. It di?ers from the closely related disciplines like Computer Mathematics, Symbolic Computation and Automated Reasoning in that its goal is to make algorithmic studies and applications of mathematics the major trend of mathematics development in the information age. The International Workshop on Mathematics Mechanization (IWMM) was initiated by Prof. Wu in 1992, and has ever since been held by the Key L- oratory of Mathematics Mechanization (KLMM) of the Chinese Academy of Sciences. There have been seven workshops of the series up to now. At each workshop, several experts are invited to deliver plenary lectures on cutting-edge methods and algorithms of the selected theme. The workshop is also a forum for people working on related subjects to meet, collaborate and exchange ideas."
This book constitutes the refereed proceedings of the 11th International Conference on Ad Hoc Networks, ADHOCNETS 2019, held in Queenstown, New Zealand, in November 2019. The 28 full papers were selected from 64 submissions and cover a variety of network paradigms including mobile ad hoc networks, sensor networks, vehicular networks, underwater networks, airborne networks, underground networks, personal area networks, device-to-device (D2D) communications in 5G cellular networks, and home networks. The papers present a wide range of applications in civilian, commercial, and military areas.

Antimalarial drugs are medicines that prevent or treat malaria, a disease which takes a great toll on human health and well-being, particularly in tropical regions including Africa south of the Sahara, South and Southeast Asia, Oceania, and parts of the Americas. In recent years, strains of Plasmodium have become increasingly resistant to more antimalarial drugs and researchers have stepped up efforts to revise antimalarial drug policies and develop new antimalarial strategies. Resistance has arisen to all classes of antimalarial (chloroquine, amodiaquine, mefloquine and sulfadoxine-pyrimethamine) except, as yet, definitively to the artemisinin derivatives. In order to prevent widespread resistance, the concept of antimalarial combination therapy (CT) has been employed and a global resistance surveillance system (World Antimalarial Resistance Networks) has been established. This book explores the use of these drugs in current health care.
