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.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
