A short sci-fi piece for those who might like it.
Ever needed to move “Program Files” to make some space with an easy 32 GB SD? Obviously, Microsoft keeps getting a backhand bribe for filling up internal drives. It turns out a nice utility called Steam Mover does the job of making a shortcut quite nicely. Windows 10 should have allowed this, and so should Windows 7. This is especially bad form when the Windows 10 upgrade installer will not use the SD for gaining the space to do an install. Where did all the GB go? On Visual Studio 2017. A bloaty C compiler.
Even LibreOffice 5 is deleting and doing failed installs. So much for being free. Part of the NSA always on spyware forced upon peoples electric processing bills. Another few GB of keywords to search through, all parasitized off you, for the nationally secure, and stuff you.
So after you check out a free demo rental of your supposed outright buy, and then you’ll have to change to another, as the megabytes increase to do much the same but slower, on faster hardware.
Yep, move a set of bits to some other volume, and all hell breaks loose. It does make you wonder why a specific Office 365 piece of code is running with a file lock when no office documents are open or used.
I like to keep updated about particle physics and LHC things, to quite an advanced level. My interest is in fields and their previous engineering value in radio waves and electronics in general. It makes sense to move to a tensor algebra in the 2+1 charge space, just as was done for the theory of gravitation. In some sense the conservation of acceleration becomes a conservation of net mapped curvature and it becomes funny via Noether’s Theorem.
CP violation as a horizon delta of radius of curvature from the “t” distance is perhaps relevant phrased as a moment of inertia in the 2+1, and its resultant geometric singular forms. This does create the idea of singular forms in the 2+1 space orbiting (or perhaps more correctly resonating) in tune with singularities in the 3+1 space. This interconnection entanglement, or something similar is perhaps connected to the “weak phase”.
So a 7D total space-time, with differing invariants in the 3D and 4D parts. The interesting thing from my prospective is the prediction of a heavy graviton, and conservation of acceleration. The idea that space itself holds its own shape without graviton interaction, and so conserves acceleration, while the heavy graviton can be a short range force which changes the curvature. The graviton then becomes a mediator of jerk and not acceleration. The graviton, being heavy would also travel slower than light. Gravity waves would then not necessarily need graviton exchange.
Quantization of theories has I think in many ways gone too far. I think the big breaks of the 21st century will be turning quantized bulk statistics into unquantized statistics, with quantization applied to only some aspects of theories. The implication is that dark matter is bent spacetime, without matter being present to emit gravitons. In this sense I predict it is not particulate.
So 7D and a differential phase space coordinate for each D (except time) gives a 13D reality. The following is an interesting equation I arrived at at one point for velocity solutions to uncertainty. I did not incorporate electromagnetism, but it’s interesting in the number of solutions, or superposition of velocity states as it were. The w being constant in the assumption, but purtubative expansion in it may be interesting. The units of the equation are conveniently force. A particle observing another particle would also be moving such, and the non linear summation for the lab rest frame of explanation might be quite interesting.
(v^2) v ‘ ‘ ‘−9v v ‘ v ‘ ‘+12(v ‘ ^3)+(1−v^2/c^2)v ‘ (wv)^2=0
With ‘ representing differential w.r.t. time notation. So v’ is acceleration and v” is the jerk. I think v”’ is called the jounce for those with a mind to learn all the Js. An interesting equation considering the whole concept of uncertain geometry started from an observation that relative mass was kind of an invariant, mass oscillation, although weird with RMS mass and RMS energy conservation, was perhaps a good way of parameterizing an uncertainty “force” proportional to the kinetic energy momentum product. As an addition it was more commutative as a tensor algebra. Some other work I calculated suggests dark energy is conservation of mass times log of normalized velocity, and dark matter could be conserved acceleration with gravity and the graviton operating to not bend space on density, but bend space through a short distance acting heavy graviton. Changes in gravity could thus travel slower than light, and an integral with a partial fourth power fraction could expand into conserved acceleration, energy, momentum and mass information velocity (dark energy) with perhaps another form of Higgs, and an uncertainty boson (spin 1) as well.
So really a 13D geometry. Each velocity state in the above mass independent free space equation above is an indication of a particle of differing mass. A particle count based on solutions. 6 quarks and all. An actual explanation for the three flavours of matter? So assuming an approximate linear superposable solution with 3 constants of integration, this gives 6 parameterized solutions from the first term via 3 constants and the square being rooted, The second tern involves just 2 of the constants for 2 possible offsets, and the third term involves just one of the constants, but 3 roots with two being in complex conjugation. The final term involves just one of the constants, but an approximation to the fourth power for 4 roots, and disappearing when the velocity is the speed of light, and so is likely a rest mass term.
So that would likely be a fermion list. A boson list would be in the boundaries at the discontinuities between those solutions, with the effective mass of the boson controlled by the expected life time between the states, and the state energy mismatch. Also of importance is how the equation translates to 4D, 3D spacetime, and the normalized rotational invariants of EM and other things. Angular momentum is conserved and constant (dimensionless in uncertain geometry),
Assuming the first 3 terms are very small compared to the last term, and v is not the speed of light. There would have to be some imaginary component to velocity, and this imaginary would be one of the degrees of freedom (leading to a total of 26). Is this imaginary velocity consistent with isospin?
Yang–Mills Existence and Mass Gap (Clay Problem)
If mass oscillation is proved to exist, then the mass gap can never be proved to be greater than zero as the mass must pass through zero for oscillation. This does exclude the possibility of complex mass oscillation, but this is just mass shrinkage (no eventual gap in the infinite time limit), or mass growth, and hence no minimum except in the big bang.
The 24 degrees of freedom on the relativistic compacted holographic 3D for the 26D string model, imply with elliptic functions, a 44 fold way. This is a decomposition into 26 sporadic elliptic patterns, and 18 generational spectra patterns. With the differential equation above providing 6*2*(2+1) combinations from the first three terms, and the 3 constants of integration locating in “colour space” through a different orthogonal basis. Would provide 24 apparent solution types, with 12 of them having a complex conjugation relation as a pair for 36. If this is the isospin solution, then the 12 fermionic solutions have all been found. That leaves the 12 bosonic solutions (the ones without a conjugate in the 3rd term generative), with only 5 (or if a photon is special 4) having been found so far. If the bosonic sector includes the dual rooting via the second term for spin polarity, then of the six (with the dual degenerates cancelled), two more are left to be found if light is special in the 4th term.
This would also leave 8 of the 44 way in a non existent capacity. I’d maybe focus on them being gluons, and consider the third still to be found as a second form of Higgs. OK.
Displacement Currents in Colour Space
Maybe an interesting wave induction effect is possible. I’m not sure what the transmitter should be made of. The ABC modulation may make it a bit “alternate” near the field emission. So not caused by bosons in the regular sense, more the “transition bosons” between particle states. The specific transitions between energy states may (although it’s not certain), pull the local ABC field in a resonant or engineered direction. The actual ABC solution of this reality has to have some reasoning for being stable for long enough. This does not imply though that no other ABC solutions act in parallel, or are not obtainable via some engineering means.
An interesting experience. The choice of FIR or IIR is the most primary. As the filtering is modelling classic filters, the shorter coefficient varieties of IIR are the best choice for me. The fact of an infinite impulse response is not of concern with a continuous stream of data, and coefficient rounding is not really an issue when using doubles. IIR also has the advantage of an easy Sallen-Key implementation, due to the subtraction and re-adding of the feedback component, with a very simple CR processing.
The most interesting choices are to do with the anti-alias filtering, as the interpolation filter, on up-sampling is an easy choice. As the ear is not really responsive to phase, all the effort should be on the pass band response levels, and a good stop band non response. A Legendre or Butterworth are the candidates. The concept of a characteristic sound enters the design process at this point, as the cascading of SK filter sections is conceptually useful to improve the -6 dB response at cut off. This is a trade off of 20 kHz to 22.05 kHz in the alias pass band, and greater attenuation in the above 22.05 kHz infinite stop desire. The slight greater desire of alias attenuation above pass band maximal flatness (for audio harmony) implies the Legendre filter is better for the purpose than Butterworth.
In the end, the final choice is one of convenience. and a 9th order filter was decided upon, with 4 times oversampling. The use of 4 times oversampling instead of 8 times oversampling increases the alias by an octave reduction. This fact under the assumption of at least a linear reduction in the amplitude of the frequency of the generator of an alias frequency, with frequency increase, just requires a -12 dB extra gain reduction in the alias filter for an effective equivalence to 8 times oversampling (the up to and the reflection back down to 6 + 6). The amount of GHz processing also halves. These facts then become constructive in the design, with the bulk alias close to the cut off, and the minor reflected alias-alias limit, not being too relevant to overall alias inharmonic distortion.
A triple chain of 3 pole Legendre filter sections is the decided design. The approximate -9 dB at the corner, allows for slightly shifting up the cut off and still maintaining a very effective stop band. Code reuse also aids in the I-cache usage for CPU effective use. A single 3 pole Legendre is the interpolation up sample filter. The roll off for not using Butterworth does cut some high frequency content from the maximally flat, hence the concept of maximally flat, but it out performs a Bessel filter in this regard. It’s not as though a phasor or flanger needs to operate almost perfectly in the alias band.
Perhaps there is improvement to be made in the up sampling filter, by post up sample 88.2 kHz noise shaped injection to eliminate all error at 44.1 kHz. This may have a potential advantage to map the alias noise into the low frequencies, instead of encroaching from the higher frequencies to the lower, and for creating the alias as a reduction in signal to noise, instead of at certain inharmonic peaks. The main issue with this is the 44.1 kHz wave fundamental, seen as the amplitude ring modulation of the injected phase noise, by the 44.1 kHz stepped waveform between samples input. The 88.2 kHz “carrier” and the sidebands are higher in frequency, and of the same amplitude magnitude.
But as this is following for no 44.1 kHz error, the 88.2 kHz and sidebands are the induced noise, the magnitude of which is of the order of 1 octave up from the -3 dB roll at the corner, plus approximately the octave for a 3 pole filter, or about 36 dB cut of a signal 3/4 of the input amplitude. I’d estimate about -37 dB at 88.1 kHz, and -19 dB at 44.1 kHz. Post processing with a 9 pole filter, provides an extra -54 dB on down sampling, for an estimate of around -73 dB or greater on the noise. That would be about 12 bit resolution at 44.1 kHz increasing with frequency. All estimates, likely errors, but in general not a good idea from first principals. Given that the 44.1 kHz content would be very small though post the interpolation filter, -73 dB down from this would be good, although I don’t think achievable in a sensible manor.
Using the last filtered sample in as the reference for the present sample filtered in as a base line, the signal at 22.05 kHz would be smoothed. It would have a notch filter effect, by injecting quantization offset ringing noise at 88.2 kHz to cancel 22.05 kHz. The notch would likely extend down in frequency for maybe -6 dB at about 11 kHz. Perhaps in the end it is just better to subtract the multiplied difference between two up sample filters using different sinc spreading of a 1000 and a 1100 sample occupancy zero inter fill. Subtracting the alternates up conversion delta as it were.
There is potentially also an argument for having a second order section with damping factor near 0.68 and corner 22.05 kHz to achieve some normalisation from sinc up-sampling. This adds in an amount of Q such as to peak the filter cancelling the sinc droop, which would be about 3% at 4 times oversampling.
EDIT: Some of you may have noticed that the required frequencies for stable filtering are too high at 4 times oversampling. So unfortunate for the CPU load an 8 times oversample has to be used. The sinc error is less than 1% at this oversample, but still corrected in a similar way, and a benefit of 2 extra poles. Following this by a 0.1 dB 3 pole Chebyshev high pass which has been inverted, gives a reasonable 5 pole up sampling filter. The down sampling filter for code efficiency is a triple instance of the sample inverse Chebyshev, with the corner frequencies slightly offset to produce more individual zeros, and some spreading of the “ringing”. These 9 poles are enough to get the stop band ripple to be lower than a 16 bit resolution. Odd order inverse Chebyshev are essential for the reflected spectra to be continually decreasing in amplitude.
I thought about making my site look like google today. The green here is distinctive, but maybe the site could learn from some google UI styling. But then maybe the net would all look the same. A bit of an off dream where the moon had all one style, and then each planet had sort of a brand. It’s more the arguments of the extents of confusion that would perhaps result from an eye catching UI, I still have not really formatted my landing page to my satisfaction. It’s an interesting thought that when the web of one planet becomes a wiki zone of another, the web becomes in effect a pivot table of UI elemental descriptions. UI design has been the defining feature of the web. Well yes, apps had it first, but there was a consistency of design in the super highway process, such that too much differentiation was counter productive in education hours.
Some have experimented with auto reflow of site HTML to modularize the CSS content, and so reduce the tweek time. A reflow portal based not just on the browser agent, but other stylistic factors could be a good future development strategy. I wouldn’t say it was a site priority here, but might be a good future project. This might be good for public spaces, where the seen that one, brings about little review.
The current focus in the roitEmbed project is the SpliceArray class. The aim being a tree array structure, where each leaf does not have to be full. The cumulative counts of the leaves make for a simple binary search algorithm to find the correct leaf and element. Splicing involves removing and adding in elements. This makes the expensive linear copy of almost all elements on a large array splice into just insertion and deletion of smaller arrays, and so makes the splice not dependant on the number of array elements. The depth of the array tree needed, depends on the maximum size and is a trade off between differing efficiencies. An optimal size for each leaf node is about sixteen elements. This means the branch nodes have thirty two elements, as both a link and a cumulative count is required. A tree depth of six allows for a 16.7 million element array maximum. This is more than sufficient for any task I can imagine being done by browser side JS.
