Book excerpt: A rising star at a preeminent political lobbying firm, Dag Calhoun represents the world's most powerful technology and energy executives. But when a close brush with death reveals that the influence he wields makes him a target, impossible cracks appear in his perfect, richly appointed life. Like everyone else, Dag relies on his digital feed for everything--a feed that is as personal as it is pervasive, and may not be as private as it seems. As he struggles to make sense of the dark forces closing in on him, he discovers that activists are hijacking the feed to manipulate markets and governments. Going public would destroy everything he's worked so hard to build, but it's not just Dag's life on the line--a shadow war is coming, one that will secure humanity's future or doom the planet to climate catastrophe. Ultimately, Dag must decide the price he's willing to pay to change the world.
Download or read book Infinite Bandwidth written by Eugene Gan and published by Emmaus Road Publishing. This book was released on 2010 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Franciscan University of Steubenville Professor Eugene Gan authors this first-of-its-kind Catholic roadmap for the digital age: Infinite Bandwidth: Encountering Christ in the Media. He navigates you faithfully through the digital world, encouraging frustrated parents not to throw out cell phones, ban the Internet, chuck computers, or pitch portable media devices. That would be a mistake and believe it or not would be going against more than seven decades of Catholic teaching. From Church documents on social communications, Gan extracts seven principles or "media keys" of how to approach and use media. The Church and Gan say that we must enter into the modern day "Areopagus," the social and intellectual hub of ancient Athens where Paul preached to pagans, and use the media tools God has given us to make truth known and serve mankind. Cardinal John Patrick Foley says, "Frankly, I wish that such a book had existed when I was president of the Pontifical Council for Social Communications as a text which I could have recommended. The important thing, however, is that it exists now to provide a text, context, and challenge for those who wish to bring both Christian principles and professional excellence to their work in the media." Gan offers chapter after chapter of real-life experience of how to assess movies, games, and gadgets for you and your teens. Of how to judge the merits of a film like Saving Private Ryan, and what sets it apart from Nightmare on Elm Street. Can the one be acceptable viewing and the other not? Definitely. And Gan details why. Infinite Bandwidth: Encountering Christ in the Media is way out front of the newest gizmo and will stay there thanks to its timeless principles that can be applied in all digital terrain, now and the future. Parents, educators, and students will put this book down with an entirely different attitude about the relationship between faith and media use.

Book Synopsis Bandwidth Allocation for Video under Quality of Service Constraints by : Bushra Anjum
Download or read book Bandwidth Allocation for Video under Quality of Service Constraints written by Bushra Anjum and published by John Wiley & Sons. This book was released on 2015-01-20 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present queueing-based algorithms to calculate the bandwidth required for a video stream so that the three main Quality of Service constraints, i.e., end-to-end delay, jitter and packet loss, are ensured. Conversational and streaming video-based applications are becoming a major part of the everyday Internet usage. The quality of these applications (QoS), as experienced by the user, depends on three main metrics of the underlying network, namely, end-to-end delay, jitter and packet loss. These metrics are, in turn, directly related to the capacity of the links that the video traffic traverses from its source to destination. The main problem that this book addresses is how much bandwidth we should allocate on the path from source to destination of a video traffic flow such that the end-to-end delay, jitter and packet loss of the video packets are within some expected required bounds.

Book Synopsis Bandwidth Recovery For Schools by : Cia Verschelden
Download or read book Bandwidth Recovery For Schools written by Cia Verschelden and published by Taylor & Francis. This book was released on 2023-07-03 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are students coming to your class lacking focus, having difficulty connecting with you and their peers, falling behind, or acting out when you instinctively feel they could do better? Do you sometimes feel like you don’t have the capacity as a teacher or school leader to give students the support they need to learn and thrive? This book makes the case that societal realities--such as poverty, racism, and social marginalization--result in depleted cognitive resources for students and for those who are trying to help them succeed. Each of us has a finite amount of mental bandwidth, the cognitive resources that are available for learning, development, work, taking care of ourselves and our families, and everything else we have to do. These “attentional resources” are not about how smart we are but about how much of our brain power is available to us for the task at hand. When bandwidth is taken up by the stress of persistent economic insecurity or the negative experiences of racism, classism, homophobia, religious intolerance, sexism, ableism, etc., there is less available for learning and growth. This is as true for young children and youth as for their parents and teachers. The first half of the book makes the case that poverty and these “differentisms” deplete the bandwidth of students, parents, and teachers. The second sets out concepts and strategies that help people recover the bandwidth they need to learn and thrive. Cia Verschelden describes strategies that can help students recover bandwidth, including acknowledging the “funds of knowledge” of students and their families, promoting growth mindsets, using reflective practices to build a sense of belonging for all students, fostering peer collaboration, and implementing restorative practices in lieu of punitive measures to deal with problematic behavior, as well as a rich selection of Ideas in Practice contributed by experienced teachers and school leaders. Cia recognizes that many teachers are working in schools with inadequate support systems and facilities and with scarce materials, and may be spending their often inadequate pay on school supplies for their classrooms and food for their hungry students. She offers practical ideas for creating moreteacher-supportive systems and addresses how principals and administrators can harness teachers’ ideas and energies to create inclusive and successful learning environments for all students. The book includes a case study of Rochester, New York – where the economy has been decimated with the closure of major employers – and how its financially strapped school system worked with colleagues at the University of Rochester to use the distributed leadership of its teachers, with the active support of principals and superintendents, to revitalize its schools to better serve its diverse and low-income student population.This book is for teachers, parents, school leaders, and members of communities who are interested in the well-being of children and youth and the education of all our children. All of us have a stake in a public school system from which students emerge as fully-formed learners and thinkers and who believe in their ability to affect what happens to them and their communities.

Book Synopsis Broad Bandwidth and High Dimensional Quantum Memory Based on Atomic Ensembles by : Dong-Sheng Ding
Download or read book Broad Bandwidth and High Dimensional Quantum Memory Based on Atomic Ensembles written by Dong-Sheng Ding and published by Springer. This book was released on 2017-12-26 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents an experimental study of quantum memory based on cold atomic ensembles and discusses photonic entanglement. It mainly focuses on experimental research on storing orbital angular momentum, and introduces readers to methods for storing a single photon carried by an image or an entanglement of spatial modes. The thesis also discusses the storage of photonic entanglement using the Raman scheme as a step toward implementing high-bandwidth quantum memory. The storage of photonic entanglement is central to achieving long-distance quantum communication based on quantum repeaters and scalable linear optical quantum computation. Addressing this key issue, the findings presented in the thesis are very promising with regard to future high-speed and high-capacity quantum communications.
Book Synopsis Bandwidth Reduction of Stimulated Brillouin Scattering and Applications in Optical Communication by : Stefan Preußler
Download or read book Bandwidth Reduction of Stimulated Brillouin Scattering and Applications in Optical Communication written by Stefan Preußler and published by Cuvillier Verlag. This book was released on 2016-10-12 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stimulated Brillouin scattering is the most dominant nonlinear effect in single mode optical fibers. Its unique spectral characteristics, especially the narrow bandwidth of 20 – 30 MHz enable numerous applications, including optical spectrum analysis, delay and storage of light, distributed sensing and optical signal processing. Most of them would benefit from a reduction of the Brillouin gain bandwidth. This dissertation demonstrates several methods for significant reduction of the Brillouin gain bandwidth, including a multi-stage system, the superposition of the gain with two losses as well as the utilization of a frequency domain aperture. Thereby the Brillouin gain bandwidth can be reduced significantly down to 3 MHz, which equals 15% of the normal bandwidth. Furthermore, the reduced Brillouin gain bandwidth is employed for various applications. First, the resolution and the dynamic range of a Brillouin based optical spectrum analyzer are enhanced significantly. Second, a new technique for the storage of optical data packets, called Quasi-Light-Storage, is introduced and the maximum storage time is increased to 160 ns for 8 bit data packets. Finally, Brillouin scattering is used for the processing of optical frequency combs, leading to the generation high quality of mm- and THz-waves, as well as almost ideal sinc-shaped Nyquist pulse sequences.
Book Synopsis Bandwidth Extension of Speech Using Perceptual Criteria by : Visar Berisha
Download or read book Bandwidth Extension of Speech Using Perceptual Criteria written by Visar Berisha and published by Springer Nature. This book was released on 2022-06-01 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bandwidth extension of speech is used in the International Telecommunication Union G.729.1 standard in which the narrowband bitstream is combined with quantized high-band parameters. Although this system produces high-quality wideband speech, the additional bits used to represent the high band can be further reduced. In addition to the algorithm used in the G.729.1 standard, bandwidth extension methods based on spectrum prediction have also been proposed. Although these algorithms do not require additional bits, they perform poorly when the correlation between the low and the high band is weak. In this book, two wideband speech coding algorithms that rely on bandwidth extension are developed. The algorithms operate as wrappers around existing narrowband compression schemes. More specifically, in these algorithms, the low band is encoded using an existing toll-quality narrowband system, whereas the high band is generated using the proposed extension techniques. The first method relies only on transmitted high-band information to generate the wideband speech. The second algorithm uses a constrained minimum mean square error estimator that combines transmitted high-band envelope information with a predictive scheme driven by narrowband features. Both algorithms make use of novel perceptual models based on loudness that determine optimum quantization strategies for wideband recovery and synthesis. Objective and subjective evaluations reveal that the proposed system performs at a lower average bit rate while improving speech quality when compared to other similar algorithms.
