Books about Filtering from Amazon.com

This book gives an introduction to the basic theory of stochastic calculus and its applications Examples are given throughout the text, in order to motivate and illustrate the theory and show its importance for many applications in e.g. economics, biology and physics. The basic idea of the presentation is to start from some basic results (without proofs) of the easier cases and develop the theory from there, and to concentrate on the proofs of the easier case (which nevertheless are often sufficiently general for many purposes) in order to be able to reach quickly the parts of the theory which is most important for the applications. For the 6th edition the author has added further exercises and, for the first time, solutions to many of the exercises are provided.

Many countries around the world block or filter Internet content, denying access to information--often about politics, but also relating to sexuality, culture, or religion--that they deem too sensitive for ordinary citizens. Access Denied documents and analyzes Internet filtering practices in over three dozen countries, offering the first rigorously conducted study of this accelerating trend.

Internet filtering takes place in at least forty states worldwide including many countries in Asia and the Middle East and North Africa. Related Internet content control mechanisms are also in place in Canada, the United States and a cluster of countries in Europe. Drawing on a just-completed survey of global Internet filtering undertaken by the OpenNet Initiative (a collaboration of the Berkman Center for Internet and Society at Harvard Law School, the Citizen Lab at the University of Toronto, the Oxford Internet Institute at Oxford University, and the University of Cambridge) and relying on work by regional experts and an extensive network of researchers, Access Denied examines the political, legal, social, and cultural contexts of Internet filtering in these states from a variety of perspectives. Chapters discuss the mechanisms and politics of Internet filtering, the strengths and limitations of the technology that powers it, the relevance of international law, ethical considerations for corporations that supply states with the tools for blocking and filtering, and the implications of Internet filtering for activist communities that increasingly rely on Internet technologies for communicating their missions.

Reports on Internet content regulation in forty different countries follow, with each country profile outlining the types of content blocked by category and documenting key findings.

Essential strategies to keep children and teens safe online

As our children and teens race down the onramp to the Information Superhighway, many parents feel left behind in the dust. News stories about online sexual predators, child pornography, cyberbullies, hate groups, gaming addiction, and other dangers that lurk in the online world make us feel increasingly concerned about what our children are doing (and with whom) in cyberspace. In Cyber-Safe Kids, Cyber-Savvy Teens, Internet safety expert Nancy Willard provides you with need-to-know information about those online dangers, and she gives you the practical parenting strategies necessary to help children and teens learn to use the Internet safely and responsibly.

Parents protect younger children by keeping them in safe places, teaching them simple safety rules, and paying close attention. As children grow, we help them gain the knowledge, skills, and values to make good choices—choices that will keep them safe and show respect for the rights of others. In Cyber-Safe Kids, Cyber-Savvy Teens, Willard shows you how those same strategies can be translated from the real world to the cyberworld, and that you don't have to learn advanced computer skills to put them into effect. As you work on these strategies with your child, you will also discover that remaining engaged with what your children are doing online is much more valuable than any blocking software you could buy.

"Willard blends the perspectives of a wise parent and a serious scholar about issues related to Internet behavior and safety. . . . Pick up the book, open it to any random page, and you will find on that page or nearby a wealth of helpful advice and useful commentary on the cyberreality facing our children and on how to deal with any of the issues she's identified."
—Dick Thornburgh, J.D., former U.S. Attorney General; chair, National Academy of Sciences Committee on Youth Pornography and the Internet

"Simply put, this book is a must-read for anyone—parents, educators, law enforcement, and policymakers alike—concerned with the critical issue of children's internet safety and what to do about it."
—Douglas Levin, senior director of education policy, Cable in the Classroom.

A bottom-up approach that enables readers to master and apply the latest techniques in state estimation

This book offers the best mathematical approaches to estimating the state of a general system. The author presents state estimation theory clearly and rigorously, providing the right amount of advanced material, recent research results, and references to enable the reader to apply state estimation techniques confidently across a variety of fields in science and engineering.

While there are other textbooks that treat state estimation, this one offers special features and a unique perspective and pedagogical approach that speed learning:
* Straightforward, bottom-up approach begins with basic concepts and then builds step by step to more advanced topics for a clear understanding of state estimation
* Simple examples and problems that require only paper and pen to solve lead to an intuitive understanding of how theory works in practice
* MATLAB(r)-based source code that corresponds to examples in the book, available on the author's Web site, enables readers to recreate results and experiment with other simulation setups and parameters

Armed with a solid foundation in the basics, readers are presented with a careful treatment of advanced topics, including unscented filtering, high order nonlinear filtering, particle filtering, constrained state estimation, reduced order filtering, robust Kalman filtering, and mixed Kalman/H? filtering.

Problems at the end of each chapter include both written exercises and computer exercises. Written exercises focus on improving the reader's understanding of theory and key concepts, whereas computer exercises help readers apply theory to problems similar to ones they are likely to encounter in industry. A solutions manual is available for instructors.

With its expert blend of theory and practice, coupled with its presentation of recent research results, Optimal State Estimation is strongly recommended for undergraduate and graduate-level courses in optimal control and state estimation theory. It also serves as a reference for engineers and science professionals across a wide array of industries.

A solutions manual is available upon request from the Wiley editorial board..

OpenBSD's stateful packet filter, PF, offers an amazing feature set and support across the major BSD platforms Like most firewall software though, unlocking PF's full potential takes a good teacher. Peter N.M. Hansteen's PF website and conference tutorials have helped thousands of users build the networks they need using PF. The Book of PF is the product of Hansteen's knowledge and experience, teaching good practices as well as bare facts and software options. Throughout the book, Hansteen emphasizes the importance of staying in control by having a written network specification, using macros to make rule sets more readable, and performing rigid testing when loading in new rules.

Today's system administrators face increasing challenges in the quest for network quality, and The Book of PF can help by demystifying the tools of modern *BSD network defense. But, perhaps more importantly, because we know you like to tinker, The Book of PF tackles a broad range of topics that will stimulate your mind and pad your resume, including how to:

• Create rule sets for all kinds of network traffic, whether it is crossing a simple home LAN, hiding behind NAT, traversing DMZs, or spanning bridges
• Use PF to create a wireless access point, and lock it down tight with authpf and special access restrictions
• Maximize availability by using redirection rules for load balancing and CARP for failover
• Use tables for proactive defense against would-be attackers and spammers
• Set up queues and traffic shaping with ALTQ, so your network stays responsive
• Master your logs with monitoring and visualization, because you can never be too paranoid

The Book of PF is written for BSD enthusiasts and network admins at any level of expertise. With more and more services placing high demands on bandwidth and increasing hostility coming from the Internet at-large, you can never be too skilled with PF.

More often than not, the words "sendmail configuration" strike dread in the hearts of sendmail and system administrators--and not without reason. sendmail configuration languages are as complex as any other programming languages, but used much more infrequently--only when sendmail is installed or configured. The average system administrator doesn't get enough practice to truly master this inscrutable technology. Fortunately, there's help. The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Say you need to configure sendmail to relay mail for your clients without creating an open relay that will be abused by spammers. A recipe in the Cookbook shows you how to do just that. No more wading through pages of dense documentation and tutorials and creating your own custom solution--just go directly to the recipe that addresses your specific problem. Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The discussion of the code is critical because it provides the insight you need to tweak the code for your own circumstances. The sendmail Cookbook begins with an overview of the configuration languages, offering a quick how-to for downloading and compiling the sendmail distribution. Next, you'll find a baseline configuration recipe upon which many of the subsequent configurations, or recipes, in the book are based. Recipes in the following chapters stand on their own and offer solutions for properly configuring important sendmail functions such as:

• Delivering and forwarding mail
• Relaying
• Masquerading
• Routing mail
• Controlling spam
• Strong authentication
• Securing the mail transport
• Managing the queue
• Securing sendmail

sendmail Cookbook is more than just a new approach to discussing sendmail configuration. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book. But most of all, this book is about saving time--something that most system administrators have in short supply. Pick up the sendmail Cookbook and say good-bye to sendmail dread..
