Dynamic Time Warping (DTW) is really interesting; it isn't something that is very well know (which is one of the reasons I'm writing this post), but it has a lot of valuable applications and is surprisingly simple to use.

I see a lot of innovative materials and applications working in the field of smart materials. One technology I find very interesting is synthetic jets.  These devices are particularly exciting due to the fact that they are in the process of transitioning from research to application.  Scientific breakthroughs and advancements in miniature electronics, efficient power supplies, low power sensors, computer modeling, and prototype testing have enabled work with synthetic jets to progress in recent years. 

Arguably one of the most critical shipboard systems is the seal which keeps sea water out, and allows the propulsion shaft to continue spinning, the Stern Tube Seal. Without it, as soon as the ship was launched, water would travel up the stern tube or through the transom directly into the ship and it would sink.

If you design, build, own, operate or repair surface ships, chances are that you will run come across vessels that have rotating shaft equipment traversing through a bulkhead that must remain watertight. After all, it won’t float if it is taking on water. You know you need to specify, purchase, or install some sort of seal, but what type of seal do you need? And will it work?

Thank you for joining me for my first webinar. I've put this together to assist those who would like to know a little more about:

In this quick video I demonstrate how we can use pressure data from the transportation monitoring example covered in my post "What Really Happens to Your Package During Transportation" to approximate the truck's location.

While putting together my previous post about "What Really Happens to Your Package During Shipment" I decided to find out if we could calculate the speed of the truck from the rotation rate of the tires?

When I had a look at the spectrograms from these transportation recordings there seems to be a waviness of the dominant frequencies throughout the 15 minute recordings that would suggest they are related to tire rotation.

So let's try to use the vibration frequency information to calculate the truck's speed!

Ever wonder what happens to your package or product during a shipment?  

 

What’s faster, MATLAB or Python?  There are a lot of forums out there comparing the two programming languages; but none seemed to give actual computation times for real analysis.  This post will.

 

As an engineer I've always been intrigued by the Tacoma Narrows bridge collapse. Just the thought of how wind can excite the bridge's structural resonance to a point where it collapses is pretty incredible.
