The article describes the procedure for transformation between old and new horizontal geodetic datum in Bosnia Herzegovina. Two triangle-based methods were used transformation, which are based on irregular regular triangular network. For development of models two set points used, one developing (around 1200 points), other testing 850 points). Prior to development, all tested at presence outlier...

<p style='text-indent:20px;'>We study convex and quasiconvex functions on a metric graph. Given set of points in the graph, we consider largest function below prescribed datum. We characterize this as unique viscosity subsolution to simple differential equation, <inline-formula><tex-math id="M1">\begin{document}$ u'' = 0 $\end{document}</tex-math></inline-formula> ...

Stochastic ordinary differential equations may have solutions that explode in finite time. In this article we prove the continuity of the explosion time with respect to the different parameters appearing in the equation, such as the initial datum, the drift and the diffusion.
