The r-Bell number ^Br(G) of a simple labeled graph G is the number of partitions of its vertex set whose blocks are independent sets of G where the _rst r-vertices are in di_erent blocks. The number of these partitions ...

In this work our purpose is to calculate the pion radiative decay constant using the formulation of Bethe-Salpeter equation under covariant Instantaneous Ansatz(CIA) after inclusion of both leading(LO) as well as ...

This study aimed at assessing the coverage of the 2015 national election of Ethiopia on the first established private FM radio, Fana F.M 98.1. The study employed quantitative content analysis. The sample selection underwent ...

The low latitude and equatorial ionosphere TEC and S4 index variability are investigated using observational data. Two GPS stations namely Addis Ababa located at geographic latitude 9°.034 N and longitude 38°.67 E and ...

Since railway is considered as optimal solution for the quickly growing transportation demand its design, construction and maintenance should get proper attention. In rail route design, we may need (be forced) to consider ...

Railways are prime mode of transportation and large infrastructures in many countries. Accidents occurring in railway transportation systems cause loss of precious lives and property. One of the major accidents occurring ...

The main focus of this study is to see how intensity of rainfall changes in the Upper Blue Nile River Basin under the conditions of the changed climate. Predicted future climate change impacts indicate that there will be ...

Flow estimation at a point in a river is vital for a number of hydrologic applications including flood forecasting, water resource management, and for development applications. This paper presents the result of a watershed ...

This is a randomized community trial which was carried out to compare the relative effectiveness of three modes of ORT in under- 5 children with acute diarrhea; to identify the factors associated with compliance and to ...

The complete set of this paper focuses on k-shortest path problem and algorithms which solve k-shortest path in a graph G where V is set of n nodes and E is set of m arcs. and I have discussed how to compute the first, ...
