Network visualization has become an increasingly important approach for how we view data in our increasingly connected world. Social networks, information networks, transportation networks, and a host of other datasets can be brought to life through network maps. However, this approach was traditionally left to those with an understanding of the complex mathematical underpinnings of graph theor…

In the early days of the web, Internet was mostly used for academic purposes. Hence, all communications protocols had very little or no focus on security. The situation started changing as more and more public and commercial services started moving online and common users started actually using Internet in their daily routine. With the increase of user base we see the emerge of the malicious gr…
These days, security is the most vital subject for any organization irrespective of their size or the kind of the business they do. The primary reason for this is that organizations don't want to lose their reputation or business over compromises affecting security; secondly, they have to meet legal and regulatory requirements. When it comes to technical security of the infrastructure, Vulnerab…
Nowadays, iOS is becoming more and more prevalent in companies and larger organizations. Whether this is a trend that is driven by Bring Your Own Device (BYOD) or something that is coming from within the IT department, our knowledge of platforms is being stretched more and more all the time. It’s getting harder and harder to be an expert on every platform that is in use in our organizations! …
As you start to look at getting into mobile development, it can be overwhelming to try and choose between all the different options and platforms available to you. Each plat- form comes with its own set of tools, preferred languages, and overall way of doing things. In many cases, you won’t want to restrict your application to a single platform, so naturally you’ll start looking for ways to…
After you’ve spent some time in the networking field, you tend to notice that there is rarely a single way to do things, and in many cases, rarely a single, precise definition for terms. After all, often a network engineer’s best answer is “it depends.” Such is the case with enterprise routing, so let’s start off with a definition question: what is an enterprise network? Is it a large…
This book describes the jobs that I and other networking engineers have performed on client networks over the past few years. We are considered network warriors because of the way that we attack networking challenges and solve issues for our clients. Network warriors come from different backgrounds, including service provider routing, security, and the enterprise. They are experts on many diffe…
Behavioral activation theory indicates that much clinically relevant human behavior is a function of positive reinforcement, and that when positive reinforcement is reduced, lost, or chronically low depression results. Behavioral activation encourages clients to obtain and nurture the skills that allow them to establish and maintain contact with diverse, stable sources of positive reinforcement…
The enterprise begins when you carefully put the first two computers together, and complexity grows with every step thereafter. Haphazard IT building practices can easily lead to an enterprise network that is poorly planned or composed of random, one-off projects undertaken as standalone goals. An e-mail consolidation project can unexpectedly derail concurrent licensing projects intended to vas…
In the first edition of this book, I claimed that humanity could be divided into three groups: (1) those who conduct their own research studies, (2) those who do not for- mally engage in the research process but nonetheless encounter the results of others’ investigations, and (3) those who are neither “makers” nor “consumers” of research claims. Now, nearly 40 years since I made that …
When asking about Information Security (InfoSec), most people immediately think about stolen credit cards, defaced web sites, and teenage hackers with names like B@D@pple. An InfoSec professional might extend the list to items like firewalls, Vir- tual Private Networks (VPN)s, penetration testing, and risk analysis. What is almost never listed is router security—network security, yes, but nev…
We have sometimes joked that there is no good reason to collect new data, given the wealth of existing data sets that can be used to answer important research questions. These existing resources are often longitudinal and usually have sample sizes that are larger than most samples typically found in psychological research. Unfortunately, our enthusiasm for the analysis of secondary data sets su…

This is a revised, corrected, enlarged, updated, and thoroughly rewritten ver- sion for a second edition of Elements of Operator Theory (Birkha ̈user, Boston, 2001). Although a considerable amount of new material has been added to this new edition, it was not altered in a significant way: the original focus and organization were preserved. In particular, the numbering system of the for- mer …

Software that drives the operations of sensors and communication among sensors is basic to any meaningful application of sensor networks. The goal of this book is to provide an understanding of how this software functions; how it allows the sensors to gather information, process it, and interact with each other in networks; and how these networks interact with the physical world. One aim of thi…

Why Mac at Work? Because everyone needs an advantage. A few years ago, I spoke at the American Bar Association’s technology conference about how I use my Mac to run circles around other lawyers. This conference happens once a year and is ground zero for cutting-edge legal technology. When I started talking to these Mac lawyers, however, their ugly secret was revealed: although they were usi…
Traditional tidal power plants (TPP-tidal barrages) result in a complete separation of a sea from a gulf in order to create one or several power producing reservoirs [1]. Such systems have a number of fundamental flaws, which hamper the development of this energy industry.
