AN IMPROVEMENT OF THE GERRETSEN’S INEQUALITY FOR NON-OBTUSE TRIANGLES
The inequality \(s^{2} \geq 2 R^{2}+8 R r+3 r^{2}\) is proved in the paper as a generalization of the Gerretsen’s en's inequality \(s^{2} \geq r(16 R-5 r)\) for (16 R - 5r ) for non-obtuse triangles.

THREE INEQUALITIES FOR THE ALTITUDES OF A TRIANGLE
The following three inequalities are considered in the paper \(h_{a}+h_{b}+h_{c} \leq 4 R+r, h_{a}+h_{b}+h_{c} \leq \tfrac{a^{2}+b^{2}+c^{2}}{2 R}, h_{a}+h_{b}+h_{c} \leq \tfrac{2 s^{2}}{3 R}\). Arrangements of inequalities are considered too.

FORECASTING OF TIME-SERIES FOR FINANCIAL MARKETS
One of the four backbones to analyze time-series in general and forecast time-series for financial markets, particularly, is the Chaos-Theory. The four backbones are: Chaos-theory, Fuzzy logic, Neural networks and Genetic algorithms. Although each method itsel...
