The central mathematical result is a theorem that can be paraphrased as follows: If the fluid model derived from an SPN is stable, then the SPN itself is stable. Two topics discussed in detail are (a) ...

[Carlos] fixed these shortcomings and created a few 3D models that accurately model the human ear and head. There’s also a simple stereo microphone amplifier for this project that is designed to ...

Like a mosaic, the cell membrane is a complex structure made up of many different parts, such as proteins, phospholipids, and cholesterol. The relative amounts of these components vary from ...

This concerns the theory of the numerical approximation of a set of equations, taken as a mathematical model of a physical system. But it concerns also the notion of the approximation involved in the ...

Our results indicate that the heavy fluid within the head of a gravity current can be transported not only in the streamwise direction but also in the spanwise direction across the lobes and clefts.

A team of materials scientists, medical researchers and engineers affiliated with a large number of institutions across ...

If you’re moving beyond foam board wings, 3D printing is an excellent way to create an accurate airfoil, and [Tom Stanton] provides us with an excellent guide to modeling wing sections for easy ...

Today's affordable 3D printers will likely surprise you: You can get a smooth-working machine with useful features once found only in high-end models. Starting at just $250, these are the top ...

More affordable than ever, 3D printers are booming for personal, professional, and educational use. Here's everything to know before you buy one, along with the top models from our hands-on testing.

These moons appear bigger and brighter looking as they are closer to Earth. The Almanac refers to this moon as the “Beaver ...

特斯拉Model Y定位于为中型SUV，同时也是特斯拉的第五款量产车型，其基于Model 3平台开发而来，因此设计风格上与Model 3十分相似。尽管外观很相似，但是车身尺寸方面，Model Y确实要比Model 3要实在很多，Model Y比Model 3长了56mm、宽了71mm、高了181mm、轴距长了15mm ...
