The electronics have already been invented to do these things. Doesn't anyone remember the invention of EGS-4 code - used for calculating the emitted gamma quantum energy that becomes deposited in the detector, estimated as follows: According to the distribution N(E,cosf) N_I quanta are generated uniformly on the bottom and collateral borders of the detector and the spectrum of their deposited energy N_loss(E) is determined. Then the pulse-height spectrum is calculated due to the formula: N_i(a_i,E)=[integral of ] [N_loss(ai,E)/sqrt[2pi](E')]exp[(E - E')2 / 2roe^2(E')]dE' where a_i is the parameter of isotopes distribution, roe(E) is the function depending on the detector specific properties. *The total number of counts in photopeak decreases and scattered to direct gamma quanta ratio increases when we increase the distribution parameter. ~ Nope, I'm surprised that our beloved Captain Mook hasn't heard of this.

For example, it’s been reported that Russian space forces monitoring HAARP (Which stands for the High frequency Active Aurora Resource Program) have discovered that within the U.S. there has been unleashed (Jan 22 I think), a considerable magnetoid "weapon" on the country of Chile, as the “Americans” had also acomplished the same on Jan 14 in Haiti.

Unfortunately, these kinds of reports put a big giant SMEAR on this kind of technology, so I'm kind of curious as to why this kind of thing is being done. Two main reasons that seem to cancel each other out - one is to present the illusion that funding for the Patriot Act needs to be taken into consideration, and the other is that some of our own elite “controllers” against these sorts of ideas (e.g. enemies of engineering “capitalism”) are forcing their will over American citizens against new technology becoming mainstream information, e.g. we are always witnessing what various psycho-dictators around the world are doing by threatening or bullying others into a position of perceived "weakness", and this is the very reason why we can see transnationalist tensions focused back on America – our enemies want to see us perceived as a “bully” all over the world because of our engineering accomplishments, and never give credence to the “human” value of our achievements. American engineers don't happen to be from "all over the world". We have a constitution, and we also have a code of ethics, unlike petty or pirate dictators. It's "If we can build it, then they will come" NOT "If THEY can build it, then WE will come". Unfortunately with privacy and newfound technology at stake in every nit and cranny throughout the WWW - nothing gets accomplished without the usual batch of naysayers and homophobes polluting the promise.

I can supply the details on how to produce the file-name.java in the current directory. The Fortran source code that may be merged directly with the source code of applet. If you are developing applets using Fortran, the recommended usage is the Lahey Fortran 90 or similar (Fortran Powerstation O.K.) You may offer your applet programs to an SAR network user community by becoming an SAR “Applet Development Partner”, and there are certain advantages for starting one’s own asteroid simulation/mapping distributive network (in terms of wider distribution).

Stiudies have been done using solar furnaces to extract the water as steam, and then recondense. A ton of oxygen can then be split from 1.125 tons of recondensed water with approximately 5 tons of asteroidal regolith (carbonaceous). Thus there is 1/10 the energy used to extract it compared to what it would take with moon dirt - ilmenite, not to mention the external source of hydrogen required - so on the contrary - the asteroid dirt produces 0.125 tons hydrogen/ton oxygen using electrolysis, and a remote source of water/oxygen is thus validated for use on manned missions." So, as stated earlier, it's just a cheaper way to go. The example that I'm presenting here is a distributively based, GUI- based program whose "master" reads, and then generates and displays a time-domain signal, distributively consisting of two sinusoids plus optional random noise, and then determines and displays the frequency spectrum of the signal. The program displays the time signal and the corresponding frequency spectrum, with GUI elements. American |

How odd. As was stated in the parallel post "How to Make Use of an Asteroid on Earth": "The regolith in asteroids is cabonaceous - a clay-like substance that yields water upon heating. Studies have been done using solar furnaces to extract the water as steam, and then recondense. A ton of oxygen can then be split from 1.125 tons of recondensed water with approximately 5 tons of asteroidal regolith (carbonaceous). Thus there is 1/10 the energy used to extract it compared to what it would take with moon dirt - ilmenite, not to mention the external source of hydrogen required - so on the contrary - the asteroid dirt produces 0.125 tons hydrogen/ton oxygen using electrolysis, and a remote source of water/oxygen is thus validated for use on manned missions." So, as stated earlier, it's just a cheaper way to go. The example that I'm presenting here is distributively based, GUI- based program whose ‘master’ reads, and then generates and displays a time-domain signal, distributively consisting of two sinusoids plus optional random noise, and then determines and displays the frequency spectrum of the signal. The distributive program displays the time signal and the corres- ponding frequency spectrum, with GUI elements. If a particular user’s applet is distributed as a purchasable item Upon WorkBench approval, then as previously mentioned, technical support to an SAR System user can utilize your applet programs on the condition that you provide back-end support to MM’s SAR technical support staff. Each approved “user” would then have the ability to coordinate the change in frequency, amplitude, and phase of each sinusoid, which would become based upon the actual x-ray and gamma frequency ranges in a “flyby” of scanned regolith. Each scan can be for a different mineral, including H2O “ice” crystal, that may be available in the C2M and C1I (“I” stands for “Ivuna”) classes of carbonaceous chrondites, each containing About 20% H2O (2% H) and 10% H2O. So what's the hangup with Semites/Nazis being too much in control of anything worth investigating - just for the sake of maintaining an interest level? Please stop the topic and/or author bashing without having anything of substance to add, otherwise please help to strengthen the impetus for establishing a better, cheaper earth-to-orbit economy without the usual NASA entitlement programs getting involved.

Thanks, American- Hide quoted text - - Show quoted text - Try establishing even a small nuke-pulsed test facility, and then leap head-first into the overlegislating requirements - "Homeland Security" will outnumber "safe use" practices ten to one! Overlegislated nuclear hazard & handling requirements can stall the delivery of nuclear materials primarily because there are more Dept. Energy "inspectors" involved, who are unable to work together in forming an accurate timeline of deliverables, which would arrive at some propulsion test facility for further manufacturing and processing of the nuclear fuel into propulsive type units. However, prior to arrival of the nuclear material, simulated pellets may be used in a prototype design for a pellet "launcher" with the following characteristics: Feed Line Design Coil for the axial magnetic field "pellet launcher" would be a "simulator" of the LHe-4 superconducting circuit. With specifications for the axial coil calculated, a correlation between the laboratory version and the working model can be made on the basis of coil life expectancy. Assuming that LHe-4 is a perfect magnetic conductor, as well as a heat sink for the injector, the coil life expectancy has to increase to withstand a specific impulse of several minutes. The ratio of coil spacing to coil radius is an important factor in determining coil efficiency. With d = coil spacing, R = effective coil radius, and p_r = pellet radius = 3.94/2, then the exiter coil and axial field coil would depend upon the design velocity, or ddw / (delta)(phi), where ddw represents the incremental change in radial frequency (sec^-1), and delta(phi) is the constant current phase angle difference imposed between adjacent coils in radians. For a 3-dome system, there are 360 coils per dome, with each representing a separate charging unit to the pellet injector. There are 600 total charging units (of 360 coils each) per thruster. The length of a single charging unit (360)(0.01313m) = 4.7268 meters, and so grouping numbers of charging units into a single fuel cell would require the length of the fuel cell to be a multiple of 4.7268 m. A 15 second fuel cell would be 15(4.7268) = 70.902 meters A 10 second fuel cell: 10(4.7268) = 47.268 meters A six second fuel cell: 6(4.7268) = 28.36 meters A five second fuel cell: 5(4.7268) = 23.634 meters 23.634 meters = 77' 6-15/32" Choosing the five second fuel cell for reasons of compacting fuel cells together into a single unit, Fuel cell_total = 600 second total impulse / 5 seconds per cell = 120 cells / thruster We're also assuming that each cell's overall diameter (w/coolant lines attached) is 7.5 cm diameter. The feed lines should support a ten minute charge or six second total specific impulse. This wwould require a total of 111,672 inches of feed lines packed with pellets. 75 lines @ 1,489 inches/line can provide a maximum pellet repitition rate of 120 pellets/second for a ten minute specific impulse. Each feed line has a machined spiral surface contour on its inside surface. The coils are individually charged with dielectric capacitors, whose thicknesses and strengths have been chosen to provide different intensities of magnetohydrodynnamic force along the length of the coil. Ideas of this sort, IMHO, are just one of the many ways in which to drive a more massive earth-to-orbit technology, but it would do so without overextending the regulation that would tend to impede, if not halt, the effort to which the R&D becomes applied. It's also the long-term follow-up that can only serve to expand our ingenuity, as well as our presence in the free-market system of extraterrestrial resource development.
