Propulsion Unit to Boost Ships’ Fuel Efficiency
The linear flow Azipod XL uses a nozzle with stator plates that directs the water flow from the propeller to reduce turbulence and energy loss and improve thrust.
Direct-to-Object Printer Inks 3-D Items
Xerox uses what it calls enhanced image-quality algorithms to direct ink-spraying nozzles.
Welding Technique Could Benefit Auto Assembly
The process reportedly consumes less than one-fifth of the energy of common welding techniques, and creates bonds that are 50% stronger.
Software Helps Designers Dampen Ship Vibration
The software guides engineers in developing and simulating elements of ship structures that incorporate actuators and sensors for self-monitoring and control of vibrations.
New Water Heater Could Lower Heating Costs
The simplified semi-open system would operate at the surrounding atmospheric pressure using an inexpensive, non-sealed solution pump.
Polymer Solar Cells One Step Closer to Mass Production
Using a mock-up of a roll-to-roll processing method, the researchers produced polymer-based solar cells with a power conversion efficiency of over 9.5%, just shy of the commercial target of 10%.
Standards Groups to Collaborate to Advance IIOT
A collaboration among three voluntary standards organizations could benefit interoperability, accelerated by manufacturers’ pursuit of the Industrial Internet of Things.
Engineering Is Popular Among Muslim Women, but Why?
Researchers hope the study will lead to greater understanding of the constraints that shape women’s participation in engineering and ways to increase the number of women studying engineering in the U.S.
I, Cobot: Standardizing Safety in Collaborative Robots
A new technical specification provides guidance on safety requirements for robot systems that work alongside humans.
Cold Start Engine Emissions
Almost all emissions in properly functioning new vehicles came out immediately after starting the cars when their engines were cold.
Workshops Impart Lessons
Workshops attempt to demystify what happens during an accident to help engineers/operators learn what decisions they might need to make in the event of a nuclear plant mishap.
China Assembles Large Amphibious Aircraft
The aircraft can draw 12 tons of water in just 20 seconds to cover a fire area of more than 4,000 square meters at once.
"Unstable" Atmosphere May Impact Wind Farm Design
Wind conditions off the coast of Massachusetts may be unstable up to 80% of the time, research suggests.
Strategic Trade-Offs in Vehicle Design Affect Market Share
Form broadly equates with a vehicle’s “cool factor.” Function and ergonomics are about performance and comfort.
Low-emission CNG Engine to Power Buses
The engine can operate on CNG or liquefied or renewable natural gas.
Engineers Without Borders USA: Taking on the Toughest Challenges
For many of the engineer-volunteers, the work with EWB-USA stands as a career highlight that reminds them of why they were first drawn to engineering.
Geotechnical Society: Getting More than "Just" a College Education
Zachary Brady invested in his future by serving as president of a campus engineering club. He discusses geotechnical engineering, the KU Geotechnical Society, and non-book learning with Engineering360.
The Engineering Firm’s Dilemma
Top management often has to be open to implementing structures and to staffing their organizations to foster collaboration.
Engineering Students Build Tiny Wheeled, Piloted Aircraft
