This paper is devoted to some up-to-date computational tools, which are on-line available and appropriate to remote learning as well as to scientific research implementation relevant to mathematics and their applications.
The following aspects are concerned and discussed: some of the opportunities and benefits afforded by the software tools which are taken into consideration; necessary requirements which have to be met in order to use these tools; some disadvantages and drawbacks which may arise.
Comparison of fees and prices for different mathematical software tools is done.
For purpose of illustration realistic examples are also given.

This report discusses the using of a free software to determine the aerodynamic coefficients of a developed MAV. The coefficients obtained, as well as the aerodynamic forces and moments, have been investigated for their applicability in the balancing and static stability of this type of aircraft. The results of the work are used to synthesize a suitable autopilot.

The present paper examines the use of free software to determine the aerodynamic coefficients of the selected MAVs. The resulting ratios and aerodynamic forces and momentums are tested for their applicability in the controlling of this type of aircrafts.
