Are there limits to exposure to microwave frequency power within a certain range, for example with workers on a transmission tower? What would be the applicable standards?
I understand that RF is non ionizing radiation, but I have read that high power RF radiation can cause burns if too...
Are there any counter arguments to the conclusions made in these papers?
Edit: by counter arguments, I mean papers written by authors who address the conclusions made in these papers or similar ideas. While the papers are not entirely rigorous, they make good points. Some things said raise my...

they have examples, and there is also a controls wiki website with examples, I believe: http://en.wikibooks.org/wiki/Control_Systems/Bode_Plots.
Given a bode plot, you look for changes in slope. At any frequency that the slope changes, first look to see...
You've probably heard this already, and it applies to anywhere on the European/Asian continents, but guard your valuables from pick pockets at all times, especially in busy places like shopping areas and especially if you have bags, backpacks, or purses.
Even unsuspecting well dressed men in...
Well, I think you are using a definition outside of OP's context. That's why I tried to clarify because it would be confusing to someone learning LTI theory. You cannot write down a non-linear transfer function that self limits in terms of a single function: O = F(I). To describe a non-linear...
I'm thinking in terms of systems and controls theory with the laplace operator. I always have been under the impression that this is the definition of the transfer function.
This fact is the inherent limitation to transfer functions in nonlinear systems and is at the heart of the OP's...
In what context are you using the word "transfer function"? Transfer functions can never be nonlinear, but you can limit their outputs after the fact that their outputs have reached the physical system's linear region limits (and no longer are modeled accurately by the transfer function). In...
I'll pass along something I picked up here a while ago.
Try researching the cepstrum technique and comb filters.
In the time domain, reflections are ideally just time delayed copies of the original signal with some distortion or attenuation, and they translate into the frequency domain as a...
Much better to have a strict thesis advisor with high expectations and well thought out goals than one who doesn't set any specific goals for you, expecting you to basically guide yourself with guesses down the road..
The example quotes you listed would only make a sensitive baby cry. However...
I think glorifying some of the encryption techniques used in internet and security as well in communication would be really cool. A poster about what people did with stuxnet and flame on the cryptography end explaining how it works and how it enabled access to computers would be really cool...
Say I have a brittle metal that I start smashing up with a hammer to crush it into a powder. How do I know how much the material's temperature will rise from this if I assume an average repetitive force crushing onto 5 grams of the material?
