Gephi is an interactive graph and network analysis and visualization tool that allows its users to study the properties of graphs and networks in detail, without having to write any code. Gephi supports almost all types of graphical networks including complex networks, hierarchical networks, dynamic networks, and temporal networks. Gephi has a lot of ready-to-use features that allow users to cr…
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.
With the release of iOS 7, Apple has also provided developers with a completely updated version of Xcode, that is, its Integrated Development Environment (IDE). Xcode 5 is a major step forward, complete with more tools and features available than ever before. Understanding the powerful features of your IDE is the key to high productivity and overall ease of development. In this chapter, we will…
Statistical distances have two very important uses in statistical analysis. Firstly, they can be applied naturally to the case of parametric statistical inference. The idea of minimum distance estimation has been around for a while and there are many nice properties that the minimum distance estimators enjoy. Minimum distance estimation was pioneered by Wolfowitz in the 1950s (1952, 1953, 195…
The American architect Louis Henry Sullivan described his design philosophy with the simple statement "form follows function." By this credo he meant that a structure's physical layout and design should reflect as precisely as possible how this structure will be used. Every door and window is where it is for a reason. He was talking about building skyscrapers, but this philosophy is perhaps …
For many decades multi-party computation (MPC) had been a predominantly theoretic endeavour in cryptography, but in recent years interest has arisen on the practical side. This has resulted in various implementation improvements and such protocols are becoming more applicable to practical situations. A key part in this transformation from theory to practice is in adapting theoretical protocols …
It’s a tough challenge to find the right depth and the right level of abstraction when introducing a new technology. A book can go too deep, and risk miring the reader in technological minutiae. This is hardly helpful, and—more often than not—it’s boring. A book can also stay at a very abstract level, and revel in theory, but even this is boring and useless for someone who hopes to achi…
To understand what cloud computing is and is not, it is important to understand how this model of computing has evolved. As Alvin Toffler notes in his famous book, The Third Wave (Bantam, 1980), civilization has progressed in waves (three of them to date: the first wave was agricultural societies, the second was the industrial age, and the third is the information age). Within each wave, there …
You are responsible for managing your company’s foreign exchange positions. Your boss, or your boss’s boss, has been reading about derivatives losses suffered by other companies, and wants to know if the same thing could happen to his company. That is, he wants to know just how much market risk the company is taking. What do you say? You could start by listing and describing the company’s…
In the social and behavioral sciences, statistics serve two general purposes. First, they can be used to describe what happened in a particular study (descriptive statistics). Second, they can be used to help draw conclu- sions about what those results mean in some broader context (inferential statistics). The main question in inferential statistics is whether a result, finding, or observation …
Microsoft officially announced SQL Server 2008, codenamed Katmai, at the first Microsoft Business Intelligence (BI) conference in May 2007. I suppose I had the same reaction as many others — ‘‘Already?’’ SQL Server 2005 had only been released a year and a half earlier, and I started to wonder if it was too soon. I can’t tell you why I thought that. I also knew that it wasn’t unu…
