We generalized our earlier result (Nahatkar and Pund [6]) with regard to the motion of a simple pendulum in a plane.

Assuming the conjecture that all effectively calculable functions must be Turing-machine computable, this paper demonstrates that the problem of recognizing Fibonacci numbers must be in general undecidable. This means that there is no algorithm, which in a finite number of steps...

In this paper we leave the neighborhood of the singularity at the origin and turn to the singularity at the horizon. Using nonlinear distributional geometry and Colombeau generalized functions it seems possible to show that the horizon singularity is not only a coordinate singula...

Tobin's one-fund theorem states that, when a portfolio is consisting of some risky assets and a riskless asset (with return rc), then every ecient portfolio in the Mean-Variance optimization is a combination of the tangency portfolio and the riskless asset. We introduce the notio...

Two di erent approaches are applied to solve high-order integro-di erential equations (IDEs), based on Radial Basis Functions (RBF). The rst approach, which is called the direct approach (DRBF) is based on di erentiation, and considers the solution as a nite linear combination of...

According to the higher computational complexity during the training process of sparse representation, the centers of granular computing (GrC) with L1-norm are regarded as the bases of sparse representation and used to reconstruct the super-resolution image of input image. Firstl...

In this paper, we propose an efficient algorithm to decompose a directed acyclic graph G into a minimized set of node-disjoint chains, which cover all the nodes of G. For any two nodes u and v on a chain, if u is above v then there is a path from u to v in G. The best algorithm f...

Emotion is an important part of human and it plays important role in human communication. Nowadays, as the use of machine getting more common, the human computer interaction (HCI) has become important. The understanding of user could bring across a better aiding machine. The expl...

We obtain a necessary and sufficient condition for L1-convergence of r-th differential of trigonometric cosine series with monotonic decreasing coefficients.

This paper presents a new and reliable algorithm for solving linear and non-linear second-order differential equations. The new algorithm is called Multiple Integral Chebyshev Wavelets Collocation Method (MICWCM). The algorithm improves some of the earlier results obtained by som...
