Plant updates can be tested before operators throw the switch on the control system. The use of simulation will likely expand considerably in 2012. Simulation is being used in new plant development, plant updates, and in configuring the plant for new products or for greater optimization.
The advantage is the ability to test the system before it is deployed. The result is a significant reduction in set-up costs -- both labor and time - and greater optimization. Plant operators report that the reduction in set-up costs alone covers the cost of using simulation. This photo shows an example of simulation used to configure robots.

Yes, things have changed dramatically in the last decade, especially in the last five years. The dot com pioneers were correct that they were changing the world. Many of them, however, got crushed in the process.
For technology journalists, opportunities have proliferated for those who moved online. Design News is a good example of journalism moving online. The print journalists -- especially those at newspapers -- either learned to write for the web or moved to a new profession.
The move online has been a long and sometimes tortured road for many publishing companies and publications, both in and out of tech. Writing for the web has been one challenge, but I think one that's been at least as tough is figuring out how to shift the print ad revenue model to online revenue sources. I know there was a lot of discussion about that in the early days.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
