NineWaves #

This cross platform - Linux, Mac OS X and Windows - F# .Net library and smartphone app to chart the nine Maya waves of Carl Johan Calleman. See Links. It uses Fabulous as F# MVU (Elm-like) frontend to Xamarin.Forms.

See YouTube video of the smartphone app for a video.

Installation and Usage#

Android#

Install the package for your smartphone (.apk for Android) onto your phone - search the web on how you can do that, this depends on your phone

iOS#

I can’t generate an iPhone package myself, so you have to build the project IOS for yourself and provision the app to your phone. Microsoft has a how-to here

NuGet Package#

Download an install the NineWaves Nuget package using your IDE (Visual Studio or JetBrains Rider) or one of the command-line possibilities: NineWaves Package at NuGet

In an interactive F# FSI session, you can use the command #r "nuget: NineWaves" to download and use the nuget package NineWaves.

Usage of the Smartphone App#

See YouTube video of the smartphone app for a video.

NineWaves NuGet Package#

Download an install the NineWaves Nuget package using your IDE (Visual Studio or JetBrains Rider) or one of the command-line possibilities: NineWaves Package at NuGet

In an interactive F# FSI session, you can use the command #r "nuget: NineWaves" to download and use the nuget package NineWaves.

To use NineWaves in an interactive session:

#r "nuget: NineWaves"

    Installed package NineWaves version 0.9.6

Everything is contained in the namespace RC.Maya, so let's open that

open RC.Maya

To check if everything's working, we call NineWaves.getWaveday9 with the DateTime of today (the 2nd of May, 2021), to get the information of the 9th wave for today.

NineWaves.getWaveday9 System.DateTime.Today

    DayNumber  OfDays  WaveNumber  IsNight
           18      18         103     True

From the returned WaveDay type we can see, that today is the 18th day (DayNumber) of 18 days (OfDays) of the 103rd 9th wave (WaveNumber). Actually it is a 'Night' (IsNight), the wave is 'below zero'.

We can do the same with all the other 8 Waves:

NineWaves.getWaveday8 System.DateTime.Today

    DayNumber  OfDays  WaveNumber  IsNight
          234     360          12    False

NineWaves.getWaveday7 System.DateTime.Today

    DayNumber  OfDays  WaveNumber  IsNight
         3474    7200           7     True

NineWaves.getWaveday6 System.DateTime.Today

    DayNumber  OfDays  WaveNumber  IsNight
         3474  144000           7     True




```F#
NineWaves.getWaveday5 System.DateTime.Today

    DayNumber  OfDays  WaveNumber  IsNight
         3474 2880000           7     True

NineWaves.getWaveday4 System.DateTime.Today

    DayNumber   OfDays  WaveNumber  IsNight
         3474 57600000           7     True

NineWaves.getWaveday3 System.DateTime.Today

    DayNumber     OfDays  WaveNumber  IsNight
         3474 1152000000           7     True

NineWaves.getWaveday2 System.DateTime.Today

    DayNumber       OfDays  WaveNumber  IsNight
         3474  23040000000           7     True

NineWaves.getWaveday1 System.DateTime.Today

    DayNumber       OfDays  WaveNumber  IsNight
         3474 460800000000           7     True

Of course we can use any date, like the 24th of October, 2014:

NineWaves.getWaveday7 (System.DateTime (2014, 10, 24))

    DayNumber  OfDays  WaveNumber  IsNight
         1092    7200           7     True

NineWaves also contains the 9 sine wave funtions for the nine waves, to generate graphs of. All 9 functions are scaled, so that 0, the wavelength and half wavelength of each wave yields 0, and each day is a integer. The maximum and minimum is reached at -wavelength / 4 and wavelength / 4.

So: for each of the wavelengths we get 0:

NineWaves.wavefunc9 NineWaves.wavelength9

NineWaves.wavefunc8 NineWaves.wavelength8

NineWaves.wavefunc7 NineWaves.wavelength7

And so on ...

Same for the half wavelength:

NineWaves.wavefunc6 (NineWaves.wavelength6 * 0.5)

-0

and of course multiplied by any integer factor:

NineWaves.wavefunc5 (NineWaves.wavelength5 * -2.)

NineWaves.wavefunc4 (NineWaves.wavelength4 * -1.5)

The maximum of 1 or -1 is reached at wavelength / 4:

NineWaves.wavefunc3 (NineWaves.wavelength3 * 0.25)

-1

NineWaves.wavefunc2 (NineWaves.wavelength2 * -0.25)

NineWaves.wavefunc1 (NineWaves.wavelength1 * -3.25)

NineWaves.wavefunc1 (NineWaves.wavelength1 * -3.75)

-1
