Richard, if we are going through the list it seems that Communication and Automobiles are more interested topics to our readers and environmental issues are the concerns, where most of them commented. I think this type of analysis will help you to plan which are the topics more interested to our community members.
It's nice to see readers interested in articles interested in issues that affect the environment, like global warming and hybrid cars. I'm expecting the environment and ways engineers and designers can improve energy efficiency in products as well as be more environmentally friendly in general to continue to be hot issues in 2013.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
