On the Role of Luminal Flow and Interstrut Distance in Modelling Drug Transport from Half-Embedded Drug-Eluting Stent
Published In: GJSFR Part: F: Mathematics & Decision Volume: 16 Issue: 6 A model for investigating the transport of drug from a half-embedded drug-eluting stent (DES) is developed. Keeping the relevance of the physiological situation in view, the luminal drug transport is considered as an unsteady convection-diffusion process, while the drug transport within the arterial tissue is supposed to commence as a diffusion process. The Marker and Cell (MAC) method h...

Using Spin, Twist and Dial Homeomorphisms to Generate Homeotopy Groups
Published In: GJSFR Part: F: Mathematics & Decision Volume: 16 Issue: 6 In this paper we consider some problems concerned with the isotopy classification of homeomorphisms of multiply punctured compact 2-manifolds, i.e., manifolds of the form X – ∪ m i=1 Definitions and Notation D̊i – Pwhere X is a closed 2-manifold, {Di :1

The Distribution of Cube Root Transformation of the Error Component of the Multiplicative Time Series Model
Published In: GJSFR Part: F: Mathematics & Decision Volume: 16 Issue: 5 In this paper, the probability density function (pdf), of the cube root transformation was derived from the ð§ð§ðÂÂÂðÂÂÂðÂÂÂð power transformation of the error component of the multiplicative time series model. The mean and variance of the cube root transformation were equally established. From the simulated r...

A New Method for Estimating Smooth Regression Functions
Published In: GJSFR Part: F: Mathematics & Decision Volume: 16 Issue: 5 We propose a new method for estimating a regression function from noisy data when the underlying function is known to satisfy a certain smoothness condition. The proposed method fits a function to the data set so that the roughness of the fitted function is minimized while ensuring that the sum of the absolute deviations of the fitted function from the data points does not exceed a certa...

Effect of Cherenkov Radiation on Superluminal Free Spin-half Particles Motion in Spacetime
Published In: GJSFR Part: F: Mathematics & Decision Volume: 16 Issue: 5 Conservation laws, consisting of the existence of quantities which do not change in time, independent of the dynamical evolution of a system, are crucial and vital for the construction of any dynamical system theory. The basic properties such as conservation of energy, momentum, angular momentum, charge, isospin, or generalization thereof are fundamental and must be guaranteed by a physi...

On the Hazard Rate Functions of Hiv/Aids using Weibull and Exponential Models
Published In: GJSFR Part: F: Mathematics & Decision Volume: 16 Issue: 5 This paper presents the hazard rate functions of Weibull and Exponential Distributions. Estimates of the hazard rates were obtained using simulated HIV/AIDs data, it was found that for exponential distribution the hazard rate is constant while that of the Weibull distribution increases as the time of infection increases. ...
