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. Over time, many changes have occurred in the combustion chamber to improve power and reduce emissions.
The Ever-Increasing Value of Modeling
Guest Blogs 5/14/2014 4 comments Engineers should have the necessary mathematical skills to solve numerical problems. Without underestimating the value of solving skills, it will be more beneficial to new engineers if future textbooks devote a majority of their pages to modeling and interpreting the results.
Congress Is Working on an Energy Bill… Again
Guest Blogs 5/14/2014 6 comments Congress is once again working on the bi-partisan Shaheen-Portman bill that will bring forth many energy efficiency measures to add as many as 190,000 jobs and save as much as 12 quads of energy by 2030.
'Necessary & Sufficient' Cover the Safety Level
Guest Blogs 5/7/2014 10 comments There are many basic principles and maxims that engineers can use to solve simple problems. One trick is to ask at least two questions. First, what is necessary to satisfy the requirement? Second, what is sufficient to satisfy the requirement?
Options for Switch-Mode Power Supply Design
Guest Blogs 5/5/2014 1 comment With renewed demand for LED lighting solutions in recent years, there are several options to get started with building a power supply. Consider the following tips, specific to electrical power supply.
Migrating Legacy Devices to the IIoT
Guest Blogs 5/2/2014 3 comments Following on the heels of breathless coverage of consumer Internet of Things (IoT) applications, the Industrial Internet of Things (IIoT) is now also garnering some well-deserved attention.
Fluid Power Is Alive & Well in the Era of Energy Conservation
Guest Blogs 5/1/2014 2 comments Despite what some people think, fluid power systems are capable of very high-performance motion control. A well-designed, closed-loop hydraulic actuator can do things that motors can't do economically and reliably, such as positioning very heavy loads with a 10-micron resolution or better.
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?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
