Shell-and-Tube Heat Exchanger - is a user friendly program which for a given heat exchanger initial conditions and geometry predicts outlet temperatures of both shell-side and tube-side fluids, heat exchanged, pressure drop on the tube sides and fluid velocity in the inlet/outlet nozzles. For a given input and output conditions the program can estimate preliminary heat exchanger design parameters.

Onefog Xonix is original realization of a well-known arcade QIX. It is played in arena, in which Enemy-balls bounce around. The Player controls a ball, which may move both around of sides of this arena and inside it, leaving a trace behind.

The software is designed as a simple accessory for teaching math. The program can represent the following objects in 3D space: regular prism (3 to 10 sides); general three-sided prism; special four-sided prism (adjustable inclination of sides); regular pyramid (3 to 10 sides). For each geometrical object, certain parameters can be interactively adjusted, such as: height and length of sides, inclination of sides, number of sides, etc.
