let r be a commutative ring with non-zero identity and m be a unital r-module. then the concept of quasi-secondary submodules of m is introduced and some results concerning this class of submodules is obtained

Warped products provide a rich class of physically significant geometric objects. Warped product construction is an important method to produce a new metric with a base manifold and a fibre. We construct compact base manifolds with a positive scalar curvature which do not admit any non-trivial quasi-Einstein warped product, and non compact complete base manifolds which do not admit any non-triv...

We analyze the parsec-scale jet kinematics from 2007 June to 2018 December of a sample $\gamma$-ray bright blazars monitored roughly monthly with Very Long Baseline Array at 43 GHz under VLBA-BU-BLAZAR program. implement novel piece-wise linear fitting method derive 521 distinct emission knots total 3705 intensity images in 22 quasars, 13 BL Lacertae objects, and 3 radio galaxies. Apparent spee...

The sales proceeds are the most important factors for keeping alive profitable companies. So sales and budget sales are considered as important parameters influencing all other decision variables in an organization. Therefore, poor forecasting can lead to great loses in organization caused by inaccurate and non-comprehensive production and human resource planning. In this research a coherent so...
