Providing up-to-date material for UWB antennas and propagation as used in a wide variety of applications, "Ultra-wideband Antennas and Propagation for Communications, Radar and Imaging" includes fundamental theory, practical design information and extensive discussion of UWB applications from biomedical imaging, through to radar and wireless communications. An in-depth treatment of ultra-wideband signals in practical environments is given, including interference, coexistence and diversity considerations.  The text includes antennas and propagation in biological media in addition to more conventional environments. The topics covered are approached with the aim of helping practising engineers to view the subject from a different angle, and to consider items as variables that were treated as constants in narrowband and wideband systems. Features tables of propagation data, photographs of antenna systems and graphs of results (e.g. radiation patterns, propagation characteristics)Covers the fundamentals of antennas and propagation, as well as offering an in-depth treatment of antenna elements and arrays for UWB systems, and UWB propagation modelsProvides a description of the underlying concepts for the design of antennas and arrays for conventional as well as ultra-wideband systemsDraws together UWB theory by using case-studies to show applications of antennas and propagation in communication, radar and imaging systemsThe book highlights the unique design issues of using ultra-wideband and will serve both as an introductory text and a reference guide for designers and students alike.

This book contains edited and revised papers from a conference on 'Science and Technology for Managing Plant Genetic Diversity in the 21st Century' held in Malaysia in June 2000, organised by the International Plant Genetic Resources Institute (IPGRI). It includes keynote papers and some 40 additional ones, covering ten themes.The major scientific challenges to developing a global vision for the next century are identified and key research objectives are also discussed.

Developing applications in a reactive style ensures that the experience

is always responsive. Akka.NET is a framework for building

distributed, message-driven applications which are able to stay

responsive for the user even in the face of failure or when faced with

more users. It makes it easy for .NET developers to write applications

which are able to react to changes in their environment.

 

Reactive Applications with Akka.NET begins with an overview of

 

reactive and a sample application written in the reactive style. Readers

will learn concepts of the actor model and what these mean in a realworld

reactive context. This hands-on book builds on fundamental

concepts that teach how to create reliable and resilient applications. It

also teaches useful Akka.NET features for building real-world

applications. By the end of the book, readers will be able to look at a

problem domain and understand how to create applications which are

able to withstand modern demands.

 

Key features:

 

• Hands-on examples that build on fundamental concepts

 

 

• Building real-world applications with Akka.NET

 

 

• Designing an Internet of Things architecture with reactive in

 

mind

 

• How to create applications that can withstand modern demands

 

 

 

 

AUDIENCE

Readers should be comfortable with C# or F# and the .NET framework. No

previous reactive experience needed.

SummaryReactive Applications with Akka.NET is a hands-on book that builds on fundamental concepts to teach you how to create reliable and resilient applications in the reactive style.Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.About the TechnologyEnterprise-scale software needs to be unfailingly reliable, consistently performant under unpredictable loads, and easy to scale and maintain. Reactive applications guarantee these qualities through clear isolation of system components and message-based communication. Akka.NET ports the battle-tested Akka Actors toolkit from the JVM, radically simplifying the concurrency and asynchronous message handling at the heart of a reactive system.About the BookReactive Applications with Akka.NET teaches you to write high-performance, concurrent systems without explicitly managing threads and locking. You''ll experience the power of Akka.NET and the Actors concurrency model by exploring a real-world case study in each chapter. As you go further, you''ll start to grok the power of asynchronous communication in a distributed environment and take on practical tasks like deploying, debugging, and establishing performance guarantees.What''s InsideReactive application designDealing with application-level failuresIntegrating Akka.NET with other frameworksApplying reactive programming to the real worldAbout the ReaderReaders should be comfortable with C# or F# and the .NET framework.About the AuthorAnthony Brown is a .NET consultant specializing in F# and reactive systems.Table of Contents
