Free ratio software for windows

Ratio is a nice tool for command line usage that will tell you compression ratio computation.
As input it receives the list of files and produces a column of compression ratios.
The first file in a list is the reference file, others are test files.
Output numbers are compression ratios between reference file and each test file.
Reference file and at least one test file should be specified.
Options:
--help (-h) Display this information
--version (-v) Display program version
--reference (-R) Reference file
--test (-T) Test file
--show-reference (-r) Use reference file as test file
--show-name (-n) Display file name
--show-size (-s) Display file size
--kb (-k)
--mb (-m)
--gb (-g) Display file size in KB, MB, GB
--percent (-p) Display percent instead of ratio
--precision Precision value

Odds Ratio Generator automatically computes the following statistics for treatment and control groups (and for improvement, no change and deterioration): Event Rates; Relative Risks; Relative Risk Increases; Event Odds; Odds Ratios; Number Needed To Treat; and Number needed To Harm.

Easy Camera Calibration 1 is created to be an intuitive yet useful program with which you can easily determine a camera's internal parameters (focal length, aspect ratio, radial distortion). The technique only requires the camera to observe a planar pattern shown at a few (at least two) different orientations. Either the camera or the planar pattern can be freely moved. The motion need not be known.

SWR Calculator 1.0 provides you a wonderful wave ratio calculator that you can use with ease. SWR Calculator can easily compute the standing wave ratio, given the power readings on a line.

Sprocket Calculator does not require any installation and is only 5kb in size.
Any kart racer might need this smart software application at some point in his career.

IfoAR2WS is a simple tool to modify the aspect ratio to 16:9 in DVD IFO files.
IfoAR2WS sets the aspect ratio to 16:9 in the video attributes of the *.IFO files of a DVD.
In the screenshot above there are 2 Video TitleSets (VTSs) in the VIDEO_TS folder. The Video TitleSet IFO files (VTS_01_0.IFO and VTS_02_0.IFO) have their aspect ratio patched from 4:3 to 16:9.
The Video Manager IFO file (VIDEO_TS.IFO) contains information about both VTSs and it too is patched from 4:3 to 16:9. The BUP (backup) files are also patched as the IFO files.
