This research focused on studying the flows of a null Cartan curve specified by velocity and acceleration fields. We have proven that tangential normal velocities are influenced binormal along motion. The fields used to drive time evolution equations for frame torsion curve. objective this work is construct family inextensible curves from initial surface formed obtained numerically visualized. ...

We apply the superfast divide-and-conquer MBA algorithm to possibly singular n × n Toeplitz-like integer input matrices and extend it to computations in the ring of integers modulo a power of a random prime. We choose the power which barely fits the size of a computer word; this saves word operations in the subsequent lifting steps. We extend our early techniques for avoiding degeneration while...

In this paper, we analyze involutes of pseudo-null curves in Lorentz–Minkowski 3-space. Pseudo-null are spacelike with null principal normals, and their can be defined analogously as for the Euclidean curves, but they exhibit properties that cannot occur space. The first result paper is more precisely, straight lines. Furthermore, a method reconstruction curve from given line its involute provi...

This paper is devoted to the controllability of a general linear hyperbolic system in one space dimension using boundary controls on side. Under precise and generic assumptions conditions other side, we previously established optimal time for null exact this source term. In work, prove null-controllability any greater than Similar results are also discussed.

In this paper, we propose a novel bagging null space locality preserving discriminant analysis (bagNLPDA) method for facial feature extraction and recognition. The bagNLPDA method first projects all the training samples into the range space of a so-called locality preserving total scatter matrix without losing any discriminative information. The projected training samples are then randomly samp...
