I'd be interested to see if this has an impact on tinnitus, which for most people who suffer it, is like audio neuropathic pain.
The USA has allowed capitalists to subvert government to impoverish its people... but look at northern Europe: highly socialist while allowing capitalism and I think a much more mature society than the USA.
Even in Australia, we are much more socialized than the USA, and yes I hate the high taxes, but it provides a much better safety net for the poor.
Yeah, but it's never really been about the reliability. It's always been the "not paying your own IT maintenance staff" thing that's the big draw.
I priced 10 2core VMs. It was 24k/annum. We do that internally on an R720 that cost 10k and needs about 3 hours a month maintenance. So for mainly internal use networks, where is the value?
10 x 2core vms is $20k
AC is correct. Most forms of subharmonic oscillation are caused by slope compensation issues, but pole filtering can also be an issue . For those who want the nitty gritty details, see this. http://www.ti.com/lit/ml/slup2...
I've designed lots of these little switch mode supplies. (SMPSs)
The noise comes from the inductors. Inductors are coils of wire around a ferrite. When the current changes through the wire, the wire physically expands and contacts from every other wire. This is the source of the noise. (SMPSs normally switch from 200kHz to 2MHz, so well outside our audio range)
There are a few things a designer can do.
1. Encapsulate the coil. This holds the wire tighter together and can minimise noise, but is only usually used in large inductors like those in invertors for UPSs or solar.
2. Eliminate subsonic oscillation with good multi-pole compensation. Switch mode power supplies have, have first second and third order responses which require filters to damp them. If you don't design these filters well, you can get subsonic oscillation which falls into the audio band. The power supply still regulates OK, but you can get that annoying whine.
3. Occasionally the noise can also come from a periodic load with that falls into an audio range. More capacitors on the output can help that.
Also, very very occasionally, it can come from ceramic capacitors that use a high k dielectric that are microphonic, but in my experience it is usually the capacitor acting as a microphone that upsets the circuit.
It describes Supercapitalism. Look it up on amazon and read the first review which summarises the concept well. Companies exists to provide the best value both shareholders and customers which deflates real wages. They play by the rules governments set, so it is up to governments to legislate the social outcomes they expect.
Have a look at the talk page.
Regardless of what you think of the subject, the article is clearly biased. Read the thread under ''What about these studies then ?''
HaHa... Modded Insightful!!
I'm encouraging my engineers to refer to GPS as GNSS, as there are 3 other systems
Glosnass, the Russian system which is now operating.
BeiDou the Chinese system also operational.
And Galileo, the EU system which has had all sorts of delays.
Yet it still the only browser that does side tabs properly with treetab plugin, which is why it still my primary browser.
What a gift to the NSA!
Or it could be church goers on the whole have a better attitude to marriage. Like 1cor13, exposing the selfless virtues of love, and the many endorsements of sticking with the partner you have chosen.
I switch to alum crystal type deoderant years ago.
They work well and last about 2 years per stick.
That's an American problem. GSM was sparingly rolled out in the US due to the prevalence of CDMA, so reclamation of those frequencies is manageable. There are no such plans for the rest of the world, where there are hundreds of millions of GSM devices still in use.
Australia is shutting down it's 2G networks to make room for LTE.
