We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the D and B fields blow up near the cloaking surface. Since the metamaterials used to IMPLEMENT cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.

Alicebot and AIML Software IMPLEMENTations The AI Foundation and our community has three open source free software "products" 1. The specification of the AIML language itself. 2. Various free software interpreters that IMPLEMENT (1). 3. The contents of the ALICE brain written in AIML (and other free AIML sets that exist).

Java Extreme Programming Cookbook offers more than just a collection of cut-and-paste code. Each recipe also includes explanations of how and why the approach works, so you can adapt the techniques to similar situations. One of the biggest challenges facing developers today is sorting through the wide variety of tools available form various source and figuring out how to them effectively. The recipes in Java Extreme Programming Cookbook showcase how to use the most important features of these XP tools. Many of these tools are geared towards unit testing, while others are invaluable for continuous integration with these practical examples, you ll be able to choose the most effective tools to accomplish your goals, then IMPLEMENT them in a cohesive development environment quickly.

Besides enhanced looks and advanced features, one of the best things about Swing is its pluggable look and feel (PLAF). PLAF architecture allows seamless changes in the appearance of an application and the way an application interacts with the user. However, designing and developing a PLAF is much more exhaustive and complex. On the other hand, themes provide a simple alternative to change look and feel of the swing application. Themes are easier to IMPLEMENT and they enhance the visual appeal of the application UI using the default Java look and feel. Theme mechanism allows a developer to easily specify the default colors, fonts and icons used by the look and feel (L&F). It allows developers to write their own themes giving them a choice to show their application GUI the way they want it, rather than depending on the defaults provided by the system.

The FPGA can realize a more optimized Digital controller in DC/DC Converters when compare to DSPs. In this paper, based on the FPGA platform, The theoretical analysis, characteristics, simulation and design consideration are given. The methods to IMPLEMENT the digital DC/DC Converters have been researched. The function module, state machine of digital DC/DC controller and high resolution DPWM with Sigma- Delta dither has been introduced. They are verified by experiments on a 20 W, 300 KHz non-isolated synchronous buck converters.
