The purpose of this study is to evaluate whether there is a correlation between the intellectual capital of employees, i.e. top managers (the agent) and the shareholder (the principal) value growth among Zimbabwean companies, listed on the Zimbabwe Stock Exchange. By using these results the aim is to further examine a possible indicator for leveraging the efficiency of intellectual capital in a...

HIV prevalence is disproportionately high among female sex workers compared to the general population. Many African countries lack useful data on the size of female sex worker populations to inform national HIV programmes. A female sex worker size estimation exercise using three different venue-based methodologies was conducted among female sex workers in all provinces of Rwanda in August 2010....

the present paper is an attempt to: 1- demonstrate how money is created (by the nature of the system), and to estimate the inflation resulting from monetary factors in both usurious and non-usurious systems. operational aspects of islamic and non-islamic banking systems are compared. 2- introduce a corrective term to be added to the multiplier of the supply of money, in order to prevent the und...

in this paper, we introduce the notion of multiplier in -algebra and study relationships between multipliers and some special mappings, likeness closure operators, homomorphisms and ( -derivations in -algebras. we introduce the concept of idempotent multipliers in bl-algebra and weak congruence and obtain an interconnection between idempotent multipliers and weak congruences. also, we introduce...

Data envelopment analysis (DEA) is a method for measuring the efficiency of peer decision making units (DMUs). Recently network DEA models been developed to examine the efficiency of DMUs with internal structures. The internal network structures range from a simple two-stage process to a complex system where multiple divisions are linked together with intermediate measures. In general, there ar...

We consider a time-dependent problem of scattering by an obstacle involving the solution of the two dimensional Maxwell’s equations in the exterior of a domain with a perfectly conducting condition on the boundary of this domain. We propose a novel fictitious domain method based on a distributed Lagrange multiplier technique for the solution of this problem. Perfectly matched layers are constru...

A new straightforward design of a special class of elliptic IIR lters is presented. The major goal is the complexity reduction of the realized digital lter. The multiplier coe cients are implemented with limited number of shift-and-add operations. This method is also called "multiplierless". Unlike classical design, a closed-form relations are derived giving relationships between the lter speci...

Many implementations of division are based on the Newton-Raphson method, as it quickly converges to a solution and can often utilize a multiplier that is already on chip. Applying time shared triple modular redundancy (TSTMR) to such a divider allows the use of a smaller multiplier and requires triplicating the divider circuit. The smaller multiplier completes larger multiplications in several ...

Digital signal processors (DSPs) are very important in various engineering disciplines. Fast multiplication is very important in DSPs for convolution, Fourier transforms, etc. A fast method for multiplication based on ancient Indian Vedic mathematics is proposed in this paper. The whole of Vedic mathematics is based on 16 sutras (word formulae) and manifests a unified structure of mathematics. ...

Field programmable gate arrays (FPGA) are increasingly being used in the high performance and scientific computing community to implement floating-point based system. The reversible single precision floating point multiplier (RSPFPM) requires the design of reversible integer multiplier (2424) based on operand decomposition approach. Reversible logic is used to reduce the power dissipation than...
