As the Internet revolution continues to unfold and transform telecommunications, pressure is building for faster, less expensive, and more widely accessible broadband service. Such a development would facilitate improved and less expensive traditional applications such as voice telephony and web browsing. It would also enable new and useful applications such as Internet-based television, videoconferencing, and software distribution. Broadband has great potential to improve efficiency and productivity, even to improve national security in some cases. Broadband service and affordability, however, have consistently lagged well behind demand and progress in information technology, with damaging results. The Internet revolution remains incomplete and threatens to stagnate if the situation continues. In The Broadband Problem, economist and technology entrepreneur Charles H. Ferguson explains the causes and ramifications of this damaging bottleneck, and he offers suggestions on improving the current state of affairs. He asserts that current telecommunications law and policy have not provided sufficient levels of new entry, competition, and innovation in the local telecom market. The continuing dominance of ILECs (incumbent local exchange carriers) in that market impedes the healthy, and much-needed, development of an efficient broadband market. The result of these policy and market failures is inadequate technological progress, innovation, and productivity in advanced Internet services and telecommunication services generally. The broadband problem is holding us back, and thus must be addressed and solved. With this important volume, Charles Ferguson has contributed mightily to that mission.

This report presents findings of a workshop featuring representatives of Internet Service Providers and others with access to data and insights about how the Internet performed on and immediately after the September 11 attacks. People who design and operate networks were asked to share data and their own preliminary analyses among participants in a closed workshop. They and networking researchers evaluated these inputs to synthesize lessons learned and derive suggestions for improvements in technology, procedures, and, as appropriate, policy.

Maintain, troubleshoot, and speed up your Mac! Version 1.0, published June 26, 2024 Macs are generally quite reliable computers, but things still can and do go wrong. When you encounter an error message, an ornery app, or other unwanted behavior, don't panic. Take a deep breath and turn to the expert advice in Take Control of Solving Mac Problems. This book—which replaces, updates, and extends Joe's earlier books Take Control of Maintaining Your Mac, Take Control of Troubleshooting Your Mac, and Take Control of Speeding Up Your Mac—is a complete guide to both preventing and solving Mac problems. You'll learn how to think like a technician, use powerful tools and techniques, and cope with surprises. The book covers three distinct areas. Maintain Your Mac Perform preventive maintenance steps that will reduce the likelihood of problems—and make it easier to recover if something does go wrong: • Make sure macOS and other software is up to date. • Free up disk space and reduce clutter. • Learn about backups, creating a troubleshooting account, and other measures to take before disaster strikes. • Explore third-party maintenance apps that may simplify common operations. • Follow a simple, ongoing maintenance routine. Troubleshoot Mac Problems The heart of the book is about diagnosing problems and finding solutions: • Learn 14 useful troubleshooting techniques that you can apply to a wide range of issues. • Find ready-to-use solutions to 25 common Mac problems. • Discover how to approach novel or unusual problems without obvious remedies. • Understand the best (and worst) ways to search for help online. • Figure out when it's time to seek professional help, and where to find it. Speed Up a Slow Mac Learn what to do if individual apps bog down or your entire system seems sluggish: • Find out what to do if web browsing is unusually slow. • Get to know Activity Monitor to find out what's going on under your Mac's hood. • Learn ways to reduce CPU and RAM usage. • Find memory leaks and tame background processes. • Determine your options for hardware upgrades when software fixes aren't enough. That's just a taste of the extensive material in this detailed, 188-page book. It's designed for Macs running macOS 11 Big Sur or later, including macOS 12 Monterey, macOS 13 Ventura, macOS 14 Sonoma, and macOS 15 Sequoia. The following Mac models are at least capable of running a supported version of macOS: • iMac (mid 2014 or later) • iMac Pro • Mac mini (late 2014 or later) • Mac Pro (late 2013 or later) • Mac Studio • MacBook (2015) • MacBook Air (2013 or later) • MacBook Pro (late 2013 or later) In other words, any Mac released in 2014 or later, plus the 2013 models of the MacBook Air, MacBook Pro, and Mac Pro.

This monograph presents a unified approach to model-based processing for underwater acoustic arrays. The use of physical models in passive array processing is not a new idea, but it has been used on a case-by-case basis, and as such, lacks any unifying structure. This work views all such processing methods as estimation procedures, which then can be unified by treating them all as a form of joint estimation based on a Kalman-type recursive processor, which can be recursive either in space or time, depending on the application. This is done for three reasons. First, the Kalman filter provides a natural framework for the inclusion of physical models in a processing scheme. Second, it allows poorly known model parameters to be jointly estimated along with the quantities of interest. This is important, since in certain areas of array processing already in use, such as those based on matched-field processing, the so-called mismatch problem either degrades performance or, indeed, prevents any solution at all. Thirdly, such a unification provides a formal means of quantifying the performance improvement. The term model-based will be strictly defined as the use of physics-based models as a means of introducing a priori information. This leads naturally to viewing the method as a Bayesian processor. Short expositions of estimation theory and acoustic array theory are presented, followed by a presentation of the Kalman filter in its recursive estimator form. Examples of applications to localization, bearing estimation, range estimation and model parameter estimation are provided along with experimental results verifying the method. The book is sufficiently self-contained to serve as a guide for the application of model-based array processing for the practicing engineer.

While the Internet revolution has vastly improved communications among businesses and individuals in the US, pressure has been building for faster and less expensive broadband data services. However, broadband services and prices have not kept pace either with demand or with progress in information technology. This title analyses the markets and policy issues underlying the broadband dilemma. Ferguson asserts that the Telecommunications Act of 1996 and federal policy have failed to provide sufficient levels of new entry, competition and innovation in the local telecommunications market, which remains dominated by monopoly telephone companies. New entrants and Internet-based firms remain disadvantaged relative to the monopoly incumbent local exchange carriers (ILEC). The combined result of these market and policy failures is inadequate technological progress, innovation and productivity growth in advanced Internet services and in telecommunications services in general. Ferguson believes federal policy must be adjusted to ensure the robust infrastructure necessary for advanced Internet services, electronic commerce, open-systems HDTV, videoconferencing and improved voice telephony.
