A closed model of the universe was constructed according to the assumption that very minor fraction of the dark energy transfers so slowly to matter and radiati
In this paper, an intrinsic relation was developed for Hyades stars between a function of the right ascensions α and declination δ with the angular distance
In order to evaluate the accuracy of bispectral estimation method, signals of cosine function were adopted. Because the cosine signals’ three order moment spec
In this work we introduced a new proposal to study the gravitational lensing theory by spherical lenses, starting from its surface mass density ∑(x) written in
