Did You Know that Time Constants May Not Be Constant?
Guest Blogs 11/17/2014 Post a comment People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
The Sound Beneath the Floors
Guest Blogs 11/13/2014 4 comments At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
What About Crowdsourcing New Components?

Does it Still Make Sense to Go Offshore?
Guest Blogs 11/3/2014 5 comments It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
354 Reasons Why Audi's SQ5 Is Worth a Look
Guest Blogs 10/23/2014 1 comment More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?

Use CFD to Design an Environmentally Friendly Car
Guest Blogs 6/23/2014 2 comments The use of CFD is more profound in automobile design because of the diverse physics involved. It can be used to optimize components for downsizing and reducing the environmental footprint while maintaining or improving operational efficiency.
Mobile Apps Speed Up Production
Guest Blogs 6/9/2014 4 comments A Detroit automaker was struggling with a semi-manual, labor-intensive parts receiving process. Workers had enter parts into a spreadsheet manually at a stationary workstation. This stopped the receiving process dead in its tracks. A better system was needed.
Turn Serial Devices Into IoT-Connected Devices
Guest Blogs 6/5/2014 2 comments We’ve all heard about how the Internet of Things will revolutionize our lives by having every asset connected to the cloud and data instantly available for analysis and display. The first step is to get those devices connected so that they can send data. The second step is for the device to know when it needs to send that data.
Sizing of Fluid Power Components Matters
Guest Blogs 6/3/2014 Post a comment For high-performance motion, the natural frequency of the system needs to be three to four times higher than the desired frequency of motion. In simple terms, the system needs to be designed to move faster than it will actually be required to move to compensate for changes in pressure.
Design a Crankless Engine
Guest Blogs 5/29/2014 27 comments Since the invention of the internal-combustion engine, a Slider Crank mechanism has been used to transfer power from the combustion chamber through the piston to the connecting rod to the crankshaft.
