For simple applications, switching devices such as contactors or solid-state relays can be used to control electrical power. The electrical power in a process can be regulated by varying the ON and OFF times of these devices. But in many processes this provision of energy in large blocks will cause significant variations in the process output. As an example, it would not be possible to control lighting levels simply by using such two-state on/off switching elements. Neither could good temperature controllers be implemented in this way...

Evolution of global technologies has prompted increasing complexity of applications
developed in both, the industry and the scientific research fields. These complexities
are generally attributed to nonlinearities, poorly defined dynamics and absence of
apriori information about the systems. Imprecision, uncertainties and vagueness in
information about the system are also playing vital roles in enhancing the complexity

Welcome to Beginning Windows 8 Application Development: XAML Edition. When I was first asked to produce
a sample table of contents for what my Windows 8 development book would include, I spent a lot of time
thinking about the aspects of Windows 8 development that I felt would be most important to help a developer
just learning to write software in a XAML-based environment.

Swarm Intelligence is a research field that studies the emergent collective intelligence
of self-organized and decentralized simple agents. It is based on the social behavior
that can be observed in nature, such as in flocks of birds, fish schools and bee hives,
where a group of individuals with limited capabilities are able to emerge with
intelligent solutions for complex problems.
When it comes to creating dynamic web sites, the open source PHP language is red-hot property: used on more than 20 million web sites today, PHP is now more popular than Microsoft’s ASP.NET technology. PHP is an ideal server-side scripting language that connects HTML-based web pages to a backend database for dynamic content. It allows you to create anything from a simple form-to-email script to a web forum application, a blogging platform, or a content management system.
