Rollover Alleys – The Dynamics for Disaster
Vehicle dynamics are an important consideration for highway design and construction. Large trucks are a common design vehicle for highway infrastructure. A variety of factors focused on large truck characteristics include: turning radius at intersections/driveways, lane widths, acceleration on upgrades, control of speed on downgrades, and more. Due to the high center of gravity (which can be exacerbated by […]
Flying into the Future
Having a BS degree in Aerospace Engineering, a recent ASME article titled, “5 Aerospace Technologies and Trends,” caught my eye.

According to a recent ASHRAE article on the study, the researchers selected average people in their own homes and monitored temperature, indoor air quality via CO2, and […]
Air Down Below
Some very good friends have a sailboat, and when I talked to them last weekend, they were working on the “brightwork.” Not knowing what “brightwork” actually was, I had to ask about it. They explained that it includes any exposed metal or varnished wood on a boat, anything that needs to be bright and shiny, […]
