A comprehensive tutorial on how to use the power of Velocity 1.3 to build Web sites and generate content Designed to work hand-in-hand with Apache Turbine, Struts, and servlets, Velocity is a powerful template language that greatly enhances the developer's ability to customize Web sites. It separates Java code from the Web pages, making a site more maintainable. Because of this, it is a viable alternative to JSPs and PHP and is expected to become the standard template engine. In addition to its use with Struts and Turbine, Velocity can also be used to generate Java and XML source code, XML schemas, HTML templates, and SQL code. Even with all its promise, finding expert instructions on how to properly program with this language has been difficult. This code-intensive tutorial gives you all the tools you'll need. It begins by quickly bringing you up to speed on all of the Velocity fundamentals and the Velocity Template Language. You'll then learn how to apply Velocity in a variety of areas with the help of richly detailed code examples. Additionally, you'll be taken through the steps of building a complete application in order to see how you can utilize all of the techniques and technologies discussed in the book. Covering the latest features of Velocity 1.3, Mastering Apache Velocity shows you how to: * Build Java-based Web sites with Struts, servlets, Turbine, and other open-source tools * Generate a wide variety of Web content and code, including Java, XML, SQL, and Postgres

This book concerns the presentation of particle velocity measurement for acoustics using lasers, including Laser Doppler Velocimetry (LDV or Anemometry (LDA)) and Particle Imagery Velocimetry (PIV). The objective is first to present the importance of measuring the acoustic velocity, especially when the acoustic equations are nonlinear as well as characterizing the near fields. However, these applications need to use non-invasive sensors. Some optical techniques, initially developed for fluid mechanics, have been adapted to the field of acoustics in recent years. This book summarizes 15 years of research in this area, highlighting the improvements that have been made, particularly in signal processing, and showing applications for which they have proven to be a carrier of innovation.

With a mandate to combat terror, the ultra-covert action team called Stony Man works outside official channels. Elite field commandos operate with real-time intelligence from master cybernetics experts. Grit and tactical brilliance are Stony Man's best weapons–and America's best chance when terror strikes from the sky to threaten the globe.An American neo-Nazi has declared war on the governments of the world. His group, Fist of Heaven, controls six weapons platforms in deep space and has launched high-shock kinetic missiles at major cities. The deadly spears have struck London, Moscow, Los Angeles and Tokyo. The death toll is staggering. America is losing the battle to save the planet from the hands of a madman. Grim and determined, Stony Man's teams prepare for the worst as they unleash their own brand of righteous retribution against the Fist of Heaven.

Operation Day CareHighly skilled combat veteran and former rodeo star Rex Trainor likes to be in the thick of the action. So when he's loaned out to Homeland Security, he plans to bide his time until he can get back to the real war. He doesn't, however, plan on Sierra Daniels, a local day-care giver whose pretty smile hides a stubborn streak more daunting than Wyoming's Beartooth Mountains. When tragedy nearly strikes the kids in Sierra's care, Rex vows to expose the culprit. Rex hasn't failed on a mission yet, and protecting the desirable Miss Daniels is no exception!
