In this paper, we investigate infinite product representation of the solution of a Sturm- Liouville equation with an indefinite weight function which has two zeros and/or singularities in a finite interval. First, by using of the asymptotic estimates provided in [W. Eberhard, G. Freiling, K. Wilcken-Stoeber, Indefinite eigenvalue problems with several singular points and turning points, Math. N...

In this paper we present a new variant of the classical Vehicle Routing Problem – the Fleet Size and Mix Vehicle Routing Problem with Backhauls (FSMVRPB). An ILP formulation of the FSMVRPB is presented. Optimal solutions for small size instances are produced and upper and lower bounds are generated for larger ones. In this paper we also propose a Set Partitioning Problem (SPP) based heuristic. ...

In 2005, Chekitan Dev and Don Schultz introduced the customer focused marketing mix (SIVA) in Marketing Management. SIVA was presented as an alternative approach to McCarthy’s classic business orientated marketing mix popularly known as the 4Ps. SIVA and 4Ps are presented here as a complementary mechanisms to shape marketing practice through considering the needs of the customer within the cons...

In this paper a new algorithm has been designed to remove the problem of over-enhancement found in Mix CLAHE especially for underwater images. The underwater image suffers from low contrast and resolution due to dispossessed visibility circumstances, hence an object identification become typical task. The processing of underwater image captured is necessary because the quality of underwater ima...

Discussions of energy and global warming policy presume that the energy mix is a system that can be engineered in order to achieve desired environmental, economic and social goals. This paper argues that such a conception can be misleading and counter-productive. Drawing on FA Hayek’s conception of the knowledge problem, and Vernon Smith’s ideas on rationality in economics, this paper argues th...
