In 2009, I published an article I thought would amuse me and no one else: a mathematical model of zombies. The idea was to examine a hypothetical zombie apocalypse through the lens of disease modelling: that is, using the same types of differential equations I use every day to examine the spread of infections such as HIV, malaria, human papillomavirus and a variety of tropical diseases. What …

For all types of businesses, there is an increasing trend towards the utilization of data, as well as information that can be gathered from data. Big Data or Data Scientist are the new terms that emerged from recent developments in the field of data and information science, just to mention a couple examples. The assurance of data quality has become an integral part of information management pr…
Paul Virilio’s major contribution to contemporary European thought has been to demonstrate that questions of visual culture are not only academic and cultural, aesthetic, historical, critical, philosophical and anthropological questions but also extremely important political questions. For Virilio, visual culture does not simply provide ways to understand the visual or examine images; it offe…
This book assumes you may have never programmed before. The book is also written for someone who may have never programmed before using object-oriented programming (OOP) languages. There are many Objective-C books out there, but all of these books assume you have programmed before and know OOP and computer logic. We wanted to write a book that takes readers from knowing little or nothing about …
So what actually is F#? In a nutshell, F# is a multi-paradigm programming language built on .NET, meaning that it supports several different styles of programming natively. I’ll spare you the history of the language and instead just go over the big bullets: • F# supports imperative programming. In F# you can modify the contents of memory, read and write files, send data over the network, an…
So what actually is F#? In a nutshell, F# is a multiparadigm programming language built on .NET, meaning that it supports several different styles of programming natively. I’ll spare you the history of the language and instead just go over the big bullets: • F# supports functional programming, which is a style of programming that em- phasizes what a program should do, not explicitly how the…
My first experience with Amazon Web Services was on March 14, 2006. I had seen a press release announcing a new web-based storage service called Simple Storage Service (S3), and I remember thinking how strange it seemed that Amazon would be offering such a service. Nevertheless, I signed up for an account and started reading the documentation. I was blown away by S3. The simple, affordable pric…
With the invention of the steamship and the opening of the Suez Canal, the time was reduced to a month or two. Air mail reduced the time further to a week or two, and eventually to a few days (“when it absolutely, positively has to be there overnight”). The deployment of commercial email systems introduced us to wait times of only a few minutes (depending on how often you polled your server…

Node.js and MongoDB are quickly becoming very popular tech stacks for the Web. Powered by Google's V8 engine, Node.js caters to easily building fast, scalable network applications while MongoDB is the perfect fit as a scalable, high-performance, open source NoSQL database solution. Using these two technologies together, web applications can be built quickly and easily and deployed to the clou…
businesses move more toward cloud computing, one important factor for success is adopting multi-tenant software-defined networking (SDN) solutions in data centers. Hyper-V Network Virtualization (HNV) is a key enabler for a multi-tenant SDN solution and is essential for implementing a hybrid cloud environment where tenants can bring not only their own IPs, but their entire network topology sinc…
Taxes have a pervasive impact on our lives. They affect every individual in the United States from birth to death, and even beyond death (through taxation of an individual’s estate). Taxes likewise affect every business from formation of the business entity to its operations, distribution of profits to owners, and ultimate disposition or liquidation. Despite the wide-ranging impact of taxes,…
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…

As distance education continues to grow in its popularity, so does the use of social networking. Hindered by concerns associated with privacy and safety, social networking sites (SNSs) are frequently banned from educational settings. The following article presents the implementation of an alternative social networking site in distance education. Findings from this study highlight the benefits…
Distance education as a primary means of instruction is expanding significantly at the college and university level. Simultaneously, the growth of social networking sites (SNS) including Facebook, LinkedIn, and MySpace is also rising among today’s college students. An increasing number of higher education instructors are beginning to combine distance education delivery with SNSs. However, …
Since the first case was recognized in the early 1980’s, the spread of the human immunodeficiency virus (HIV), which causes acquired immune deficiency syndrome (AIDS), has achieved pandemic proportions (CDC, 1981; UNAIDS, 2006). According to the latest report from the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) (2009), HIV/AIDS continues to be a…
For nearly 50 years, the United States has led the world in the scientific exploration of space. U.S. spacecraft have circled Earth, landed on the Moon and Mars, orbited Jupiter and Saturn, and traveled beyond the orbit of Pluto and out of the ecliptic. These spacecraft have sent back to Earth images and data that have greatly expanded human knowledge, though many important questions remain una…
In response to a request from Congress, the Institute of Medicine (IOM) convened a committee to conduct an analysis of the federal government’s quality enhancement processes in six government programs—Medicare, Medicaid, the State Children’s Health Insurance Program, the Department of Defense TRICARE and TRICARE for Life programs, the Veterans Health Administration program, and the Indian…
Adverse weather has a major impact on aviation safety and efficiency. During 1988–1992, one-fourth of all aircraft accidents and one-third of fatal accidents were related to weather (Salottolo, 1994). In addition, 41 percent of air traffic delay time during 1990 was attributable to weather. These delays accounted for approximately $4.1 billion of direct costs to the airline industry—not inc…
Over the last few years, corporations have been under incre- ased pressure to optimize resource utilization while at the same time adapting more quickly to changes required by the business. This pressure has direct impact on IT organizati- ons faced with more complex installations that need to be implemented, enhanced and managed with fewer allocated resources. Most organizations have invested…
