Application of depth methods to functional data provides new tools of analysis, in particular an ordering of curves from the center outwards. Two specific depth definitions are band depth and half-region depth (Lo ́pez-Pintado & Romo (2009). Journal of the American Statistical Association, 104, 718–734; Lo ́pez-Pintado & Romo (2011). Computational Statistics & Data Analysis, 55, 1679–1695…
Enterprise application development over the decades has been a pendulum swinging back and forth between terminal and mainframe, between client and server. In the 1980s, business logic was largely pushed to the server by "dumb terminals" or "thin clients" which did very little except act as a middleman between the user and the server. Beginning in the 1990s, logic started to swing to the client…
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 this chapter, we will cover the major components that almost all alarm systems have in common. By the end of the chapter you will realize that the so-called high tech alarm systems and access control systems are not really as complicated as some would like you to believe. That said, let's get started. Every alarm system in the world does two and only two basic things. • It monitors the wor…
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 …
This is the least fun—but nevertheless critical—part of the book, where we walk through setting up an environ- ment in which to write and test Python. We are going to do a crash course in setting up a Kali Linux virtual machine (VM) and installing a nice IDE so that you have everything you need to develop code. By the end of this chapter, you should be ready to tackle the exer- cises and co…
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…
In a relatively short period of time, Android has become the world’s most popular mobile platform. Although originally designed for smartphones, it now powers tablets, TVs, and wearable devices, and will soon even be found in cars. Android is being developed at a breathtaking pace, with an average of two major releases per year. Each new release brings a better UI, performance improvements, a…
Network security is currently becoming one of the main problems for the develop- ment of new technologies and services in telecommunication networks. Hackers are constantly evolving towards new attack techniques and new target tech- nologies at a very high speed [1] [2], thus making the task of building defense mechanisms a hard mission. In this context, many efforts have been done by the rese…
Currently, computer networking has already become ubiquitous, the number of diverse devices is increasing constantly, as are also their capabilities, the range of applications and network-based services is expanding, and user expectations are rapidly evolving. This is the context in which the authors set the scene for this net- work programming book in its introductory chapter. The past decade…
Government intervention is perhaps the most universal institutional change in the development of modern economies. Yet there is considerable debate on the relationship between economic development and the expansion of government. The relationship has been viewed as causal, but both directions have been emphasized. To many, government fosters economic growth. To others, economic growth, because …
APIs are becoming increasingly popular for exposing business functionalities to the rest of the world. According to an infographic published by Layer 7, 86.5% of organizations will have an API program in place in the next five years. Of those, 43.2% already have one. APIs are also the foundation of building communication channels in the Internet of Things (IoT). From motor vehicles to kitchen …
Welcome to Absolute FreeBSD! This book is a one-stop for system administrators who want to build, configure, and manage FreeBSD servers. It will also be useful for those folks who want to run FreeBSD on their desktops, servers, diskless system farms, and so on.
The aim of this book is to provide an introductory treatment of time series econometrics that builds upon the basic statistical and regression techniques contained in my Analysing Economic Data: A Concise Introduction.1 It is written from the perspective that the econometric analysis of economic and financial time series is of key importance to both students and practitioners of economics and s…
“The suspense was killing me. I just had to read it straight through!” Although these responses to our book would be gratifying, it’s doubtful that any book on digital security will ever garner this type of reaction. Digital security is the computer equivalent of disaster insurance. Few people care very much about it or give it much thought, and everyone hates paying for it … until a ca…
“Now, of course, a free and open internet is vital. But in no other market and with no other industry do we have such an extraordinarily light touch when it comes to protecting our children. Children can’t go into the shops or the cinema and buy things meant for adults or have adult experiences; we rightly regulate to protect them. But when it comes to the internet, in the balance between f…
Recently, the number of social networking sites is rapidly increasing, and the number of users joining these sites is dramatically increasing as well. This paper aims at comprehensively comparing three social networking sites, and provides an in-depth analysis. We compare three of the most popular social networking sites, i.e., Facebook, Twitter and MySpace. Specifically, we evaluate those soci…
In 2014, UN Member States proposed a set of Sustainable Development Goals (SDGs), which will succeed the Millennium Development Goals (MDGs) as reference goals for the international development community for the period 2015-2030. The proposed goals and targets can be seen as a network, in which links among goals exist through targets that refer to multiple goals. Using network analysis techniqu…
