Unsteady MHD Free Convective Flow Past an Inclined Parabolic Accelerated Plate with Hall Current, Radiation Effects and Variable Temperature in a Porous Medium
(International Journal of Management and Fuzzy Systems, 2017)We analyze the effects of hall current and radiation on unsteady hydromagnetic free convection flow of a viscous incompressible electrically conducting fluid past an inclined parabolic accelerated plate in a ... -
Using Conditional Extreme Value Theory to Estimate Value-at-Risk for Daily Currency Exchange Rates
(Scientific Research Publishing Inc., 2017)This paper implements different approaches used to compute the one-day Value-at-Risk (VaR) forecast for a portfolio of four currency exchange rates. The concepts and techniques of the conventional methods considered in ... -

A VCSEL-based backbone extended-reach optical fibre network: Supporting up to 10 Gbps flexible access networks for Africa
(2018)In this paper, using vertical cavity surface-emitting lasers (VCSELs) and Raman amplification, a low power consuming, energy-efficient and cheap technique to transmit high speed data signals over optical fibre is ... -
Vehicular Traffic Flow Model with Driver Aggresiveness Component in a Multilane Road
(Journal of Applied and Computational Mathematics, 2016)In this study, we outline the Kerner’s 3-phase traffic flow theory, which states that traffic flow occurs in three phases and these are free flow, synchronized flow and wide moving jam phases. A macroscopic traffic flow ... -
Volatility Estimation of Stock Prices using Garch Method
(European Journal of Business and Management, 2015)Economic decisions are modeled based on perceived distribution of the random variables in the future, assessment and measurement of the variance which has a significant impact on the future profit or losses of particular ... -
Zn and Pb marking of Ca binding to humic substances and PHREEQC speciation simulations
(IWA Publishing, 2016)Power generating companies using and recycling cooling water usually experience deposition of insoluble salts on pipes carrying the water, leading to scaling problems. By controlling parameters that optimize competitive ...
