Finding the best investment is an interesting optimization problem. When we deal with such a problem in an uncertain and vague environment, the optimization problem becomes more difficult. In this paper, we deal with rough data expressed in the form of an inexact rough interval f...

A model for the dynamics of homogeneous population competition between two species of weeds and a crop is formulated to gain in-sight into the behaviour of crop growing with weeds. We used assumptions based upon reasonable biological process to derive from single weed model equat...

Recently, Williams [1] and then Yao, Xia and Jin [2] discovered explicit formulas for the coefficients of the Fourier series expansions of a class of eta quotients. Williams expressed all coefficients of 126 eta quotients in terms of σ(n) σ(n/2), σ(n/3) and σ(n/6) and Yao, Xia a...

The Unified Modeling Language (UML) is a general-purpose visual modeling language for specifying software-intensive systems. More precisely, it is a graphical language for visualizing, specifying, constructing and documenting the artifacts of software-intensive systems. UML is a...

This paper proposes a new meta-heuristic approach to solving continuous optimization problems using 21 benchmark test cases. The African buffalo algorithm evolved from an understanding of this animal’s survival instincts and the search techniques they utilize in the African fores...

Over the last decade, various mobile robots have been developed and widely used in myriad sectors. However, the vast majority of mobile robots are manually designed where the designers must have the preliminary knowledge of the interaction between the robots with the environment....

Diagnosability is the property of a partially observable system with a given set of possible faults; these faults can be detected with certainty with a finite observation. Usually, the definition and the verification methods of diagnosability ignore the nature of controllable and...

Aims/ objectives: Let Q1; Q2 and Q3 be three non-vanishing meromorphic functions, and be an entire function. In this paper, we consider the dierential equation of the form: and derive some necessary conditions ( in terms of Qj (j = 1; 2; 3) and ) for the existence of an admissibl...

We establish the inequality where is superquadratic and prove a more general inequality where 1/2n and 2n -1/2n are replaced by a/2n and b/2n respectively, with a+b=2n ,n ∈ N, the latter is extended to the case where a+b ≠ 2n , n ∈ N.
