TPMath is a library of scientific programs written in Pascal. Available in several versions according to the compiler, it is proposed as an Alternative to the famous Numerical Recipes, for which the Pascal version is no longer developed, or to the Borland Numerical Methods Toolbox which is no longer available.

Free Space Optical Communication (FSOC) is an effective Alternative technology to meet the Next Generation Network (NGN) demands as well as highly secured (mili- tary) communications. FSOC includes various advantages like last mile access, easy installation, free of Electro Magnetic Interference (EMI)/Electro Magnetic Compatibil- ity (EMC) and license free access etc. In FSOC, the optical beam propagation in the turbulentatmosphereisseverelyaffectedbyvariousfactorssuspendedinthechannel, geographicallocationoftheinstallationsite,terraintypeandmeteorologicalchanges. Therefore a rigorous experimental study over a longer period becomes significant to analyze the quality and reliability of the FSOC channel and the maximum data rate that the system can operate since data transmission is completely season dependent.
