This book will address the advances, applications, research results, and emerging areas of optics, photonics, computational approaches, nano-photonics, bio-photonics, with applications in information systems. The objectives are to bring together novel approaches, analysis, models, and technologies that enhance sensing, measurement,...

With more and more images and videos being available in the compressed format, researchers have started taking interest in the aspect of designing algorithms for different image operations directly in their domains of representation. This would not only avoid the inverse and forward transformation steps and potentially make the...

Cryptography has made a peculiar journey to become a modern science. It had long been associated with the military and with magic. The rst published work in the eld was Steganographia, by an alchemist named Trithemius. Although written earlier, the book was published in 1606. Cryptography has continued this connection with the arcane...

Change: It’s what we expect from technology, from the PC to the web, through to HD TV. But nothing has been as disruptive as the change the iPhone and Android phones have brought. For the first time the power of a computer will fit in your hand, you are always connected to the Internet, and these devices are loaded with...

PHP on the server side and jQuery on the client side (browser) are a killer...

A quick look at your local bookstore’s Internet section will tell you that there are quite a few commercial packages out there for building web sites. What those books often fail to mention is that many of the world’s most popular web sites were built using freely available tools, and run on free operating systems (OS). They...

Storage technologies have fundamentally changed the landscape of digital media in a profound way. Gone are the days of using a single hard disk drive on a workstation as the sole means to store digital content. Nearly vanished is the practice of capturing video and audio only on videotape. The practice of transferring videotape...

On the other hand I've...

Joomla is an open source content management system (CMS) that anyone can download for free (see forge.joomla.org/sf/go/projects.joomla/frs). This makes it an ideal choice for small businesses. Don’t let the price tag fool you, though; Joomla is powerful and robust, and more big organizations are choosing to use open source software...

In UNIX there are many ways to accomplish the same task. Given a problem to solve, we may be able to get to a solution in any number of ways. Of course, some techniques will be more efficient, use fewer system resources, and may or may not give the user feedback on what is going on or give more accurate details and more precision to the...

Projec t manageme nt has been around for centuries. After all, how do you think the Pyramids were built? Organizations have come to recognize that a lot of the work they do is project-oriented. And when they realize that good project management can save both time and money, that’s about the time that people like you receive the...

Game playing is a powerful metaphor that fits many situations where interaction between autonomous agents plays a central role. Numerous tasks in computer science, such as design, synthesis, verification, testing, query evaluation, planning, etc. can be formulated in game-theoretic terms. Viewing them abstractly as games reveals the...
