Introduction
Computer security is undeniably important, and as new vulnerabilities are discovered and
exploited, the perceived need for new security solutions grows. "Trusted computing"
initiatives propose to solve some of today s security problems through hardware changes
to the personal computer. Changing hardware design isn t inherently suspicious, but the
leading trusted computing proposals have a high cost: they provide security to users
while giving third parties the power to enforce policies on users computers against the
users wishes -- they let others pressure you to hand some control over your PC to
someone else. This is a "feature" ready-made for abuse by software authors who want to
anticompetitively choke off rival software.
It needn t be this way: a straightforward change to the plans of trusted computing vendors
could leave the security benefits intact while ensuring that a PC owner s
Have you ever seen players eyes light up as they explore the worlds that you ve created in your games? If you have, then game development probably has you hooked firmly in its grasp! If you ve never taken your games beyond the PC, now s the time! "J2ME Game Programming" is a hands-on guide that teaches you how to create games for micro-devices. You ll be amazed at just how cool the games you create can look and play. Focusing primarily on mobile phone game creation, you ll jump right in and create your own games as you work your way through the book. The thought has surely crossed your mind that it would be nice to make some money off of this cool hobby of yours. J2ME offers real opportunity to profit from your games. Learn how you can earn revenue from your games by taking them to market. If you have a basic understanding of Java, then you re ready to explore all that "J2ME Game Programming" has to offer!
Since the advent of optical communications, a great technological effort has
been devoted to the exploitation of the huge bandwidth of optical fibers. Start-
ing from a few Mb/s single channel systems, a fast and constant technological
development has led to the actual 10 Gb/s per channel dense wavelength di-
vision multiplexing (DWDM) systems, with dozens of channels on a single
fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds
of channels can be simultaneously amplified by optical amplifiers.
Many good textbooks exist on probability and random processes written at the under-
graduate level to the research level. However, there is no one handy and ready book
that explains most of the essential topics, such as random variables and most of their
frequently used discrete and continuous probability distribution functions; moments,
transformation, and convergences of random variables; characteristic and generating
functions; estimation theory and the associated orthogonality principle; vector random
variables; random processes and their autocovariance and cross-covariance functions; sta-
tionarity concepts; and random processes through linear systems and the associated
Wiener and Kalman filters.
When 3GPP started standardizing the IMS a few years ago, most analysts expected the
number of IMS deploymentsto grow dramatically as soon the initial IMS specifications were
ready (3GPP Release 5 was functionallyfrozenin the first half of 2002and completedshortly
after that). While those predictions have proven to be too aggressive owing to a number of
upheavals hitting the ICT (Information and Communications Technologies) sector, we are
now seeing more and more commercial IMS-based service offerings in the market. At the
time of writing (May 2008), there are over 30 commercial IMS networks running live traffic,
addingup to over10million IMS users aroundthe world; the IMS is beingdeployedglobally.
In addition, there are plenty of ongoing market activities; it is estimated that over 130 IMS
contracts have been awarded to all IMS manufacturers. The number of IMS users will grow
substantially as these awarded contracts are launched commercially. At the same time, the
number of IMS users in presently deployed networks is steadily increasing as new services
are introduced and operators running these networks migrate their non-IMS users to their
IMS networks.
I am presenting this novel book on advances and trends in power electronics and motor
drives to the professional community with the expectation that it will be given the same
wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer-
sity professors, and even graduate students that my other books in this area have. Unlike
the traditional books available in the area of power electronics, this book has a unique
presentation format that makes it convenient for group presentations that use Microsoft’s
PowerPoint software. In fact, a disk is included that has a PowerPoint file on it that is
ready for presentation with the core figures. Presentations can also be organized using
just selected portions of the book
