WARRANTY: Absolutely none - Use At Own Risk!

Updated 5/14/2008, update work-in-progress, not yet official.

GENERAL NOTES ON DON KLIPSTEIN WEBSITE SOFTWARE unless otherwise noted:

1. Executables (ready-to-run) DOS 3.0 or higher, which is supplied with or required to install (and remains after installing) Microsoft Windows 3.x, 95, or 98. Windows XP "cmd" so far works.

2. For programs not noted as "shareware" (requesting payment), source code is posted here (in a link). Download and compile the source code if you do not trust me to not infect my executibles with nasties such as viruses (virii?) or worms. Source codes are mostly in BASIC and unless otherwise noted compileable with Microsoft Quick Basic 4.5 (and probably most lower versions down to 2.5) and probably compileable with all versions of Microsoft Visual Basic either as-is or with minor changes. In addition, BASIC source codes will probably be largely to possibly entirely-as-is workable in most versions of Borland TurboBasic.

3. Most Microsoft Basic compilers 2.5 to 7 (at least for DOS) and maybe some other Microsoft programming languages (especially BASIC) have some strange extraneous slowdown in floating point math. There is a patch!

My Computer Speedup General Hints (mostly old)

.ZIP file with the patch for speeding up many Microsoft BASIC compilers such as Quick Basic 2.5 to 4.5, BASIC 7 ("QBX"), and possibly some other Microsoft programming language / compiler packages such as some versions of Visual Basic.

Now For The Programs!

Number of Programs Available Here as of 5/14/2008: 2 (two).

MWPL - "mW/lm" UV and blackbody spectrum plot
Radiate - brightness, chromaticity, spectrum breakdown of blackbody radiators as a function of temperature

MWPL - "milliwatts per lumen" blackbody radiation spectrum

This program requests user input of "blackbody radiator" (ideal thermal radiator) temperature in degrees Kelvin (limited to a range of 1720 to 31600). Its response is screen output of a spectral distribution curve with horizontal calibration in wavelength in the range of 250 to 850 nanometers. Vertical scaling is obviously enough percentage of peak (in content per unit "bandwidth") but calibrated for a custom purpose in terms of milliwatts of ultraviolet per lumen of visible light. (I got off my butt and developed this program where the customer wanted ultraviolet data to minimize fading of paintings in an art gallery.)

Additional output displayed on the screen is milliwatts of UV per lumen of visible light.

REQUIREMENTS:

"IBM-Compatible" PC or "PowerPC" sort of computer, video display including VGA compatibility, operating system suitable for running a DOS program (DOS version preferably 3.0 or higher, but may run on DOS as low as about 2.3 or so).

Preferred processor for fast speed "X86" type Intel 486DX or higher, AMD 5X86 /"X5" or higher or equivalent. Will work on 8088 or higher.

To print output while using DOS, before running MWPL run the DOS utility GRAPHICS. While what you want to print is displayed, do a -PrintScreen. Your paper output may have black and white reversed.

Source Code Notes:

Successfully compiled with Microsoft Quick Basic 4.5.

For faster execution, use the "MATHPTCH" which gets around some slowdowns of floating point math by many Microsoft Basic compilers and maybe some other Microsoft program languages/compilers.

Download Links:

MWPL.EXE executable with the "mathptch" speedup worked in.

MWPL.BAS Basic Source Code compileable by Microsoft Quick Basic 4.5, freeware including blackbody formula and photopic data useful for such programs.

RADIATE - brightness, chromaticity, spectrum breakdown of blackbody radiators as a function of temperature

This program requests user input of "blackbody radiator" (ideal thermal radiator) temperature in degrees Kelvin (limited to a range of 350 to 2E7 degrees Kelvin. Its response is to print onto the screen the following properties of a blackbody radiator at such a temperature:

Surface brightness in candela/cm^2
Scotopic/photopic ratio
Peak wavelength in nm
1931 CIE chromaticity coordinates
Watts radiated per square centimeter
Percent of total radiation in vacuum UV, non-vacuum UVC, UVB, UVA, visible, IRA, IRB, and IRC
Overall luminous efficacy, in lumens of light per watt per total radiation.

REQUIREMENTS:

"IBM-Compatible" PC or "PowerPC" sort of computer, video display with CGA or VGA compatibility, operating system suitable for running a DOS program (DOS version preferably 3.0 or higher, but should run on DOS as low as 2.1).

Preferred processor for fast speed "X86" type Intel 486DX or higher, AMD 5X86 /"X5" or higher or equivalent. Will work on 8088 or higher.
