Preliminary experiments reveal that the human microenvironment has a significantly higher content of microorganisms than the ambient air. The source of bacteria is either the skin and/or the ambient air. Since some of the air of the microenvironment is inhaled during the respiratory cycle, this may...

The wind tunnel the Wright Brothers built helped changed the course of human technological history. Stringer/Hulton Archive/Getty Images Because whirling arms chopped the air and created wake that invalidated many experiments, scientists needed calmer, artificial winds. Frank H. Wenham, an Englishman...

“It’s often thought that a particularly advanced motorcycle requires a huge amount of electronics aid, but that’s not the case. By working on different dynamic and aerodynamic features there is less of a need to develop the bike’s electronics.Wing surfaces act intelligently by developing sta...
The material I chose again for modeling is silicone rubber as I don’t see “human Nasal Mucosa Flesh” in my Autodesk drop down menu. The flow rate on all is 5 liters/minute. (restful breathing) I applied a boundary condition of 20C for the incomin...
题目Northwestern University engineers have added a new capability to electronic microchip:flight. About the size of a grain of sand,the new flying microchip does not have a motor or engine.Instead,it catches flight on the wind — much like a maple tee's seed — and spins ...
The models do not need human-selected parameters and are more accurate. 4 Interactive analysis Interactive exploration and analysis of the features can help users better understand the flow field, and deep learning can play a variety of roles in this process. For example, selection of streamlines...
