Thirty-six full matrix forms of the Pascal triangle: Derivation and symmetry relations
For all 2≤n∈N, the four vertices (00),(n0),(2nn),(nn) of the Pascal Triangle expanded from level 0 to level 2n define the greatest embedded rhomboid sub-block denoted n−GRSB in this paper.

Comment on “Defining a curve as a Bezier curve”
In a recent article published in this journal, Baydas and Karakas show how to compute the Bézier representation of a curve given in power form. We note that this straightforward exercise, including a closed-form expression for the transformation matrix ...

Expression of strain tensor in orthogonal curvilinear coordinates
Based on an analysis of connotation and extension of the concept of the orthogonal curvilinear coordinates, we have deduced a platform of strain tensor expression of Cartesian coordinates, which turns out to be a function of Lame coefficient and unit ...

Loop Transfer Matrix and Loop Quantum Mechanics [PDF]
We extend the previous construction of loop transfer matrix to the case of nonzero self-intersection coupling constant $\kappa$. The loop generalization of Fourier transformation allows to diagonalize transfer matrices depending on symmetric difference ...
