How to evaluate online banner ad options

Often times when discussing print and online advertising opportunities with customers I hear "can you just 'throw in' some online banner ads like the other publications are doing?" and this raises a red flag. We all like the feeling of getting a good deal... especially in the work place when you're handling negotiations like ad buying b/c you want the pat on the back from your boss. The question you need to ask though is "what is the value of the online advertising component?" that the…

What's better? A formal or an informal change process?

There's a lot of give and take when it comes to setting up a change process, and a lot of factors that determine if your process should be highly formalized, or loosely managed.

A loose change process, where individual engineers have the discretion to either expedite change requests or make immediate revisions, exposes your product to unintended consequences - - including costly scrap and rework at best and field failures at worst. But excessive review slows down the iterative process…

pumps and frequency inverter (variable speed drive)

pumps and frequency inverter (variable speed drive)  

All of us know that frequency inverters are widely used in many applications for energy saving. They are tools that is used to change the frequency of electricity.

Below is application of frequency converter used for pumps.

Usually pumps are sized to cope with the maximum predicted flow, leading to the motors running at part load. The result is low motor efficiency and a low power factor which…

PLCs, Malicious Software, and Cyber Warfare

It isn't every day that PLCs and national security are mentioned in the same sentence. Although perhaps they should be. Which is why this segment from CBS's "60 Minutes" on the Stuxnet virus caught my attention. The piece sheds some light on the shadowy world of computer viruses and how software is being used by state military and intelligence agencies to conduct stealth wars by attacking the very unglamorous control infrastructures that are controlled by PLCs.
