the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...

Prime graph of a ring R is a graph whose vertex set is the whole set R any any two elements $x$ and $y$ of $R$ are adjacent in the graph if and only if $xRy = 0$ or $yRx = 0$.  Prime graph of a ring is denoted by $PG(R)$. Directed prime graphs for non-commutative rings and connectivity in the graph are studied in the present paper. The diameter and girth of this graph are also studied in the pa...

where Fin = 1/Tin (Tin) and Fout = 1/Tout (Tout) are the original input sampling rate (period) and the sampling rate (period) after the conversion, respectively. The sampling rate conversion can be divided into two general cases. For R < 1, the original sampling rate is reduced and this process is known as decimation. For R > 1, the original sampling rate is increased and this process is known ...
