The energy eigenvalues with the Extended Cornell potential were obtained by analytically solving the radial Schrödinger equation using the Exact Quantization Rule technique (ECP). It was then used for computing the mass spectra of the heavy mesons like ch... see more

The notion of a U-exact sequence is a generalization of the exact sequence. In this paper, we introduce a rough U-exact sequence in a rough group in an approximation space. Furthermore, we provide the properties of the rough U-exact sequenc... see more

Rough Set Theory (RST) is an essential mathematical tool to deal with imprecise, inconsistent, incomplete information and knowledge Rough Some algebra structures, such as groups, rings, and modules, have been presented on rough set theory. The sub-exact s... see more

New exact inequalities for Hadamard fractional derivatives of functions, defined on the half-line, are obtained.

Let  be a ring,  a strictly ordered monoid, and K, L, M are R-modules. Then, we can construct the Generalized Power Series Modules (GPSM) K[[S]], L[[S]], and M[[S]], which are the module over the Generalized Power Series Rings (GPSR) R[[S]]. In ... see more

Higher homotopy of graphs has been defined in several articles. However, the existence of a long exact sequence associated to a pair (G, A) has not been touched at. We treat it here. Applied to the discrete spheres, this lead to interesting open questions... see more

O desenvolvimento de qualquer sociedade depende em grande medida do nível que a ciência e a técnica têm alcançado. Nas últimas décadas a computação tornou-se em uma ciência que determina a possibilidade de alcançar metas mais altas de bem-estar e prosperi... see more

En este artículo se hace un análisis del problema de las redes de transporte en las cadenas de suministro, considerando sus limitaciones y restricciones y las soluciones de optimización dadas usando métodos exactos y heurísticos. Se describen los tipos de... see more

This paper, which is part of a research based on the theoretical framework of the Theory of Conceptual Fields, investigated the performance of first-year undergraduate students attending Exact Sciences courses at the State University of Maringá, Brazil, w... see more
