Free space optical communication FSO links have several features that make them attractive because they supply equip high bandwidth, high bit rates, low bit error rates, low cost, security, and it is a reliable communication ...

In this paper, we consider singular linear systems of algebraic equations on the form We introduce formulas for the Moore- Penrose generalized inverse of depend on the ranks of , and based on the adgugate matrix. Using ...

The purpose of this article is to extend some more topics of topology in neutrosophic topology. We introduce the concept of neutrosophic pre-approximation space and its properties. Pre-open (pre-closed) sets are investigated. ...

In this presented paper, we are concerned with the oscillatory behaviour of solutions of some nonlinear ordinary differential equations of second order. Primarily, we are interested in the study of equations with integrable ...

Many biologists have used heterophil-to-lymphocyte ratio (HLR) cells from peripheral blood as an indicator of stress in many animals, including both wild and captive birds. However, there has been little research on ...

This paper will study and analyse the content of the statistics curriculum for the high school (the 11 and 12 year) for the scientific and literary sections. This paper studied the existing problem represented in the ...

Pedestrian navigation systems help us make a series of decisions that lead us to a destination. Nowadays, public displays spread in public spaces and have become available and useful in many purposes for people's life ...

In this paper, we study the inviscid limit for the Navier-Stokes stratified system in space dimension two with a real valued function F depend only on the temperature θ. Precisely we prove the weakly convergence in the ...
