On blackouts and cascading failures
An article in Scientific American last month discussed an interesting analogy, namely the one between the electricity network and global financial networks.
According to the author Jeffrey D. Sachs, both are network systems in which a local problem can undergo a system-wide amplification leading to a general catastrophe. Such amplification is caused by what Sachs calls 'rational panics'. Each node in the network has certain rational rules that are created to protect its own stability. However, if all those rules should conclude simultaneously to withdraw from the system, the whole network starts collapsing.

During this event, you will discover what thermal imaging and thermography are and how they work. Examples of the most common industrial applications will show you how thermography can help you save costs in your plant. You will see how to use thermography to find problems and faults in everyday inspection of equipment and processes, and how to use software for analysis and comprehensive reporting of your findings in the field. There will also be an opportunity to ask questions about your application and where to find relevant documentation on thermal cameras and common applications.

Last week we wondered why a superb fan control heavily tries to cool a 17°C cold PC power supply with 17°C cold air. Here you see the package of last week's PC power unit, which promises a “higher” air flow and 60% noise reduction. 60% of what? I can tell you from a disappointing experience that the reference must have been said vacuum cleaner.Read full article
