If you haven't been using CAD software all your life, I recommend SolidWorks and Nastran. Stay away from traditional big money guys like ProE unless you are forced into it by peer useage. Your aspirin bill will be a lot less. I also recommend www.cati.com as support people. If nothing else...
If you have time, go to dogpile.com, and search for 'rubber seals and o-rings'. Pretty much go down the list requesting engineering tips and catalogs. Most will have basic specs in their literature. As for specifically applying to your face seal problem, my experience is with high pressures...
I would think the ultrasonic energy is going to be highly directional. An accelerometer is going to be sensitive only in directions you point it. I think you need something like a black body absorber which will convert the ultrasonic energy to heat. Measure the temperature change to measure...
Have fun reading. Another fun one is www.dieoff.org for us pessimists.
If a path to the better there be, it lies in taking a full look at the worst.

What becomes of the surplus of human life? It is either, 1st. destroyed by infanticide, as among the Chinese and Lacedemonians; or...
A good post. I would like to add that if you are so inclined, seek out an understanding of ac electronics. You can learn most of it with a trig level of understanding, and most of the principles of vibration are the same. (harmonics, frequency domain to time domain conversions, the test...
I am not one for conspiracy theories, as I think that most government conspiracies usually are just the symptom of some bozo in a free money-for-nothing job trying to cover his own ass. However, if you are interested, you can go to www.infinite-energy.com and get the latest scoop on the new...
I didn't actually address the original question of what has been done in the last year. I would suggest that you go to www.countrysidemag.com , or do some searching for sustainable living/simple living groups. The progress to be made will not be in technology, except to step back and apply...
A good position. I have a 50 acre farm, my goal is to establish a sustainable system on it using a combination of animals, tree crops, and field crops, including pasture. (but first, I have to work to pay for it, no homestead act here anymore :-)) I have just read a book titled simply...
It has been a while since anyone posted on this, but I want to put in a few cents worth about standardizing. If you try to seek and use an existing standard, you will probably end up with less than you desire for economizing spaceflight. The Arianne card cage packaging...
I faxed it this morning. I hope it was clear. If not, go to productdiscovery.com (I hope this is o.k, Dave). I will get a message left there.
How fast are the cylinder ends moving? Is there something preventing you from directly measuring position via externally connected linkages with potentiometers? How clean will the pistons remain? (will reflectivity change over time?) How accurate does...
Does this tractor have a fuel pump in the tank to feed the injector pump? If so, that pump could be the culprit. Either by not pumping, or it may have a bad check valve which allows the fuel to drain back into the tank at night. Once the fuel is pumped to the main pump during extended...
