  1. When I was young, a pastor once told me I was like Gideon. He told me that I was amongst the tall grasses and hiding, but that it was my place of learning and that one day I would rise up win the war and become a great leader of Man. That said I am probably never going to be a great leader of men and well even if it came to be, the merit of these claims . . . people like stories. I associate 'word salad' with schizophrenia. A failure to immediately disclose framework is usually a causal sign of an inability to produce or is sign of the prior. I cannot extrapolate any meaningful mathematics from the description given. Your statement about "checking your mathematics" suggests you have mathematical models of such natural phenomena. As a reader of your post I see no such realization and am left to wonder. I can't visualize your proposal as given and this is probably why the moderators moved it into speculations and hence my post. If you want to discuss this seriously it would require further investigation via proper analysis, which in physics requires the proper use of both pure and applied mathematics. Having an education you should be privy to such mentality; you should probably know better! p.s. I would really like to discuss this properly! *---------------------------------------------------------------------------------------------------* For starters, can you fill out the blanks of how this would develop through say Hilbert Space? I'm not terribly familiar with this level of physics but Hilbert Spaces seem play an important role in such theories . . .. .
  2. Thank you Cap'! <3
  3. I had--really stupidly--changed my display name back in May. The Change Display Name tab was allowing us to change our nicks every 180 days. On Saturday I was going to be able to change my nick, but the tab suddenly disappeared on Friday. I understand if Administration decided to change the policy on this, but now I'm stuck with my shame. I was really hoping to just go back to using Xittenn as it is the nick I go by everywhere else. If this might be corrected for me, it would be much appreciated?? I promise to stop being a git ( I blame hormones ). . . It had occurred to me that the tab might be glitched where I used it and broke it and everyone else still has the tab . . . . I actively imagine scenarios like these :/ I much appreciate what you guys are doing here, thanks! Beka:D
  4. Most audio amplifiers operate in what is known as class A/B, biased push pull. Class A/B operates in nearly Class B mode. In class B mode an amplification circuit is constructed so that the positive half of the waveform is driven by half of the topology and the negative by the other. The problem with this class is there is an excessive amount of crossover distortion where the one half of the circuit relinquishes and the other takes over. This is partially caused by transistors natural operational values where they do not maintain linearity in their first ~volt, but this is another story. In class A/B a small bias is introduced to offset the output above this distorted operational zone. In effect each stage is biased so that they operate, on avg. 5% to 10%, into the opposing swing of the waveform. The crossover zone is then canceled when recombined and put through the coupler. The final coupling stage tends to be a rather large capacitor. Because passive components tend to have variating values based on frequency a sudden introduction of direct current will produce an oscillation. The circuitry is trying to level out, and this oscillation will take a few RC time constants to dissipate. So essentially when you turn on the amplifier all the circuits are charging up and the process causes the oscillation that you hear. If this were a purely class B amplifier, chances are probable that you would not hear it. If you are making a comparison to other devices, either the effect was too small to notice or the device was driven using a different circuit topology(of which there are many.) My own stereos and sub-woofers did this all the time. I think most of the mid range to mid-hi range stereos do this, where some hi-hi range systems utilize soft start circuitry to help protect the longevity of the internal components. Class A tube amps, where the waveform is completely biased into a given potential and where half of the output power is consumed across a coupling stage resistor, I'm sure made a rather large thump :/ Any old people in the forum to corroborate? I hope to go 300B someday . . . . . . even though old age has taken >15khz away from me :<
  5. Like employing the death penalty for acts of homosexuality in countries of Africa? Retardation? Sorry, I'm being callously biased against idiocy, erm . . . ignorance! They simply do not see the benefits of acting in an other fashion, probably because for them there really aren't any. In fact their present methods may even be the most beneficial to the masses as the costs of other forms of justice may for them be greater. Apples . . . . . . .
  6. I think the closest technology to accomplishing this is Wolfram Alpha, but it utilizes its own internal database to collect the required information to compile an answer to a question. I don't see why it couldn't be reconfigured to analyze the same data present on the net. I think the main reason for not doing so is accuracy of information or rather a lack of common misinformation!
  7. Graphing calculators are handy things!
  8. Like say a variable conductive elastic material whose ohmic resistance changes with the amount it has been stretched? Where said material could be fashioned into a balloon like structure and filled to different levels with a liquid. After which a measurement of said materials ohmic resistance could be mathematically analyzed to equate to a certain contact force?
  9. Plot your guess and confirm? You should be able to check this on a graphing calculator. On the ti-83 trace with a polar graph still gives the x and y coordinates which is sucky . . . . . but easily converted to r . . . . :/
  10. Only because the technology referenced by the op was this Sixth Sense: Mistry and Maes scroll down for ted videos
  11. This is an oddly posed question. I think in general, in gaming as noted by our op, it's safe to say that the frames are usually submitted individually. This is often done in .tga format, and then depending on the engine they are compressed. For example Source provides a tool that converts a series of .tga's to .vtf ( valve texture file ) which is compressed DXT or other format depending on the options chosen. This question is specific to the engine and tools being used, and so difficult to properly answer. . . . which I assume is why no one had? Targa takes up a lot of space : D
  12. Zombie Movies \o/ and new shoes as well . . . . . .
  13. Cellular and Molecular Neurobiology Ginko Biloba?
  14. Generally speaking 'scientific discovery' suggests 'empirical evidence' accomplished through 'experimentation' or 'observation.' Although your evaluation allows an outline for what could be experimentally evaluated it leaves much in terms of 'imagination' and is therefore a weak proposal. All I'm saying is these thoughts you are having have been loosely conceived of by many of the members of this forum . . . . . . That said I still place my vote on atmospherically stable magnetically contained plasmas and meat rockets \o_ one day I'll do the math . . . . until then . . . I will program stuff to do the math . . . . . and hope for a solution to scar tissue!
  15. If it is irrational in binary how would it be rational in hex? Hex codes for binary so if it requires an infinite set of binary decimal places than it will require an infinite set of hex decimal places to code for it . .. . .
  16. .2 is irrational in binary but rational in BCD. This means that computations that require precise decimal representation become less precise with the use of binary as rounding is involved. This extends to floating point mathematics under each respective representation! "precise decimal representation" == common base 10 decimal numbers ie. .2
  17. Wiki's article on Binary Coded Decimal offers up several answers to this question. I don't think there is one thing in particular that BCD does that the others do not that fits this question precisely. The few things that are mentioned however do serve as the main factors for choosing to use this numerical representation for computational purposes. I'm particularly fond of its uses in representing certain values more precisely than other similar methods of numerical representation. Someone with more experience might help so . . . .
  18. I'm sorry, but, you said something about mathematics? I wish I could do mathematics : <
  19. I remember my other hate . . . . I hate that there are no free native to windows compilers for Fortran. ACML is only compiled by either of ifort or pgi . . . . I hate that acquiring a tuned BLAS for my AMD processors requires me to spend >$700 or my doing it myself(epsecially when the BLAS is free.) I do however like the idea of doing it myself, although in the end I would still be required to roll my own Fortran compiler, or buy it from PGI or Intel to code my [math] \equiv [/math] LAPACK. That is all!
  20. I hate that my ISP has blocked port 80 and wishes to charge me an extra $40/month to unblock it, reduce my dl speed by 10Mbps, and give me a static IP . . . . . I hate that due to multiculturalism the average man outside my family, and in my community, is short and thin. I also hate how in general people stare up at me . . . . I hate people who give me crap for excessive use of ellipsis . . . . I am an emotional person and people need to know when I am being emphatic! I hate scar tissue and wish someone would find a cure dammit . . . . I hate the cold, needles, shoes that blister my feet, growing old, getting fat, not having the money to buy a new outfit everyday : D I might come back to this one, I forgot one of significant importance and . . . . . I hate forgetting things all the time. I hate that editing my posts leaves a stupid message and all I've done is speel check . . . .
  21. There are reference texts that avoid developing concepts and serve merely as a list of equations such as: "Table of integrals, series and products" by Iosif Moiseevich Ryzhik, Alan Jeffrey, Daniel Zwillinger "Matrix mathematics: theory, facts, and formulas" by Dennis S. Bernstein If you disregard application ie. Physics, I'm sure there are enough of these books to cover a good deal of the equations. This obviously would mean no cross referencing for say the Normalization Constant with say Hermite Polynomials. This would be a very nice encyclopedia collection and I'm sure one day, if it doesn't already, it will exist. Hell of a lot of reading . . . .
  22. I don't think there is a standard that defines Packet Error Rate explicitly. And if somewhere in the megatons of literature there is one, well there are several different standards, so you would be required to be more specific. I think it's safe to say that most would just include the resent packages in their figures, but these would represent some small fractions of their values. Your statement "This would imply that there's a difference of a total PER and the PER given by the BER value." is kind of 52 card pick up and I prefer to not spend my time guessing at the meaning of these kinds of statements. If a packet is resent and has an error a second time, and the error is different then the measured PER and BER may be different in contrast to such a package never having ever existed. This said I think that it is safe to say that claims given of PER and BER in real life communications are in fact averages of observed and measured PER and BER during testing or from logging of such events. What does it really matter though? These figures simply give an idea as to the effectiveness of the system in use and do not play such important roles beyond that of guesstimating figures for settings in traffic control. Given the small discrepancies in the difference between the two possibilities well .. . . .
  23. Pre-Production: 1) Define the scope of the project - how long do you have - what do you believe you can accomplish/4 - how long did it take someone else 2) Assess the technologies you will use - what technologies have you used - what technologies are required - budget 3) Define your platform - whose technologies will you use - whose technologies are documented in such a way that they are manageable by you - whose technologies will meet your budget 4) Develop a Project Plan - Assign a budget and break it into its components - schedule all of your tasks dates and amount of time 5) Project Documentation - Technical Document; what and how - Project Document; logic behind(why), goals, interfaces, utility, references - cross reference both documents; what is being achieved(PD) => how(TD) Technologies: 1) Audio/Visual Input/Output - cameras - microphones - projectors - audio transducers 2) Audio/Visual Pattern Recognition - processors designed for this purpose - languages; c++, java, haskell . . . . - software components on market; haskell packages - platform API; COM/.NET, Android, Java . . . . 3) Central Processing - base platform; netbook, iphone . . . . windows 7 phone - memory; persistent, processing, cache . . . . etc. ??????????
  24. gratz Briggs & Cochran Calculus: Early Transendentals gives a good description of the shell method as well! [math] V = \int^b_a 2 \pi x ( f(x) - g(x) ) dx [/math]
