The device's diameter is larger than most of the wavelengths it produces. This allows the device to create a wavefront that's more flat than rounded, keeping the sound from dispersing. Air interferes with sound waves as they pass through it. As the LRAD's sound waves interact with the ai...
you should go back and readmy previous FDM texturing tutorial here, but the main thrust is, the bigger your layer line heights, the coarser and blockier your texture will look, when the printer tries to render it on a flat horizontal face: ...
Trend interpolation creates a gradually varying surface using low-order polynomials that describe a physical process—for example, pollution and wind direction. However, the more complex the polynomial, the more difficult it is to ascribe physical meaning to it. Furthermore, the calculated surfaces ar...
Then lower the body of the tape measure over the side of the RV and lay the pole flat on the roof.Be careful to avoid banging the tape measure into the side of the RV as you lower it down. Confirm that the electrical tape is holding the tip/end of the tape measure directly against...
This step requires you to be very meticulous. Carefully transfer the measurements (offsets). They may or may not look correct because it's very non-intuitive to look at curved boat parts that are laying flat. Some parts actually bend the opposite way you think they should. To make the cu...
“When do you want the envelope rather than the field itself?” Lens simulation is one example. Sometimes you may need the intensity rather than the complex electric field. Actually, the square of the norm of the envelope gives the intensity. In such cases, it suffices to get the envelope...
, you will see by slackening the little chain now more and now less, that it curves and adapts itself to the parabola; and the agreement will be the closer, the less curved and the more extended the parabola drawn shall be. In parabolas described with an elevation of less than 45°, ...
Measuring highly reflective 3-dimensional curved surfaces on multiple vegetables and incorporating digital software tools to interpret their blackness values naturally lead to human judgement choices in final measurements. The experimenters were conscientious of this and did their best to be consistent in ...
material when it's installed, a slight dip in the edge (which can be caused by hand finishing) can look very bad. If the edge has to be straight and square, a table saw with the right blade is what you'll need to use to make the cuts (especially in materials thicker than 1/8"...
Use a metal file to file flat surfaces into the rounded nut or head of the bolt, making it easier to grip with a wrench. Heat up the nut or bolt with a propane torch for 30 seconds to loosen it, then unscrew it with a wrench or pliers. 1 Lubricate the nut or bolt with WD-40...
