in this paper, we first define spaces of single difference sequences defined by a sequence of orlicz functions without convexity and investigate their properties. then we extend this idea to spaces of double sequences and present a new matrix theoretic approach construction of such double sequence spaces.

Our paper has two goals: i) We propose the combinatorial approach to facilitate the calculation of the number of spanning trees for five new classes of graphs. ii) We use a new powerful operation (subdivision) to get larger graphs from a given graph. In particular, we derive the explicit formulas for the subdivision of ladder, fan, triangular snake, double triangular snake and the total graph o...

Several approaches have been introduced in literature for active noise control (ANC)systems. Since Filtered-x-Least Mean Square (FxLMS) algorithm appears to be the best choice as acontroller filter. Researchers tend to improve performance of ANC systems by enhancing andmodifying this algorithm. This paper proposes a new version of FxLMS algorithm. In many ANCapplications an online secondary pat...

This paper presents a simplified computation approach for the machine path (or winding trajectory) of grid structures and tubes with circular cross-section angle-ply or double-double layup. The solution is given through controllable degrees freedom low-cost two-axis filament (FWM): mandrel rotation translation delivery eye along axis mandrel. efficiency analytical FWM was ascertained by automat...

Let $G$ be a connected graph, and let $D[G]$ denote the double graph of $G$. In this paper, we first derive closed-form formulas for different distance based topological indices for $D[G]$ in terms of that of $G$. Finally, as illustration examples, for several special kind of graphs, such as, the complete graph, the path, the cycle, etc., the explicit formulas for some distance based topologica...

The kernel of the echo canceller is the adaptive filter, which is used to estimate the impulse response of the echo path by means of an adaptive algorithm. During double-talk, the near-end input signal contains not only the echo of the far-end input signal, but also the near-end talker’s speech. In this case, the adaptation may be greatly disturbed because the far-end input signal doesn’t corre...

this paper proposes a simple but efficient technique to control 3d overhead crane. load musttrack a desired path and not sway more than a reasonable range.the proposed method uses pidcontrol for trolley to track the desired path and fuzzy control compensation to eliminate the loadswing. only the projection of swing angle is applied to design the fuzzy controller. no plantinformation of crane is...
