Modelling credit risk for personal loans: Cox Proportional Hazards Model Approach
(Pushpa Publishing House, 2012-08)A proportional hazards model approach was adopted to estimate risk of default for loan applicants. A sample of 500 applicants was observed for 36 months. The life of the account is measured from the month, it was opened ... -
Modelling Inflation Rate Volatility in Kenya Using Arch -Type Model Family
(2016)This paper describe the empirical study based on financial time series modelling with special application to modelling inflation data for Kenya. Specifically the theory of time series is modelled and applied to the ... -
Modelling Influenza Dynamics with Drug Resistance Aspect
(2017)Despite improvement in medical and public health standards, influenza continues to plague humankind causing high morbidity,mortality and socio-economic cost. Efforts to effectively combat the spread of influenza can be put in ... -
Modelling Multi-Mutation and Drug Resistance: A case of Immune-Suppression
(Research India Publications, 2018)A model that takes into account multi-mutation and drug resistance in a case of simple immune system and immune-suppression caused by drug resistant tumor cells is proposed. Since methods for revising therapeutic approaches ... -
MODELLING THE VOLATILITY OF EXCHANGE RATES IN RWANDESE MARKETS
(European Centre for Research Training and Development UK, 2014-12)This work applied Generalized Autoregressive Conditional Heteroskedasticity (GARCH) approach to modelling volatility in Rwanda Exchange rate returns. The Autoregressive (AR) model with GARCH errors was fitted to the daily ... -
Modelling the volatility of exchange rates in the Kenyan market
(Academic Journals, 2010)This paper considers the application of the generalized autoregressive conditional heteroscedasticity process in the estimation of volatility in the Kenyan exchange rates. A quasi-maximum likelihood estimation procedure ... -
Modulation of the interfacial electrochemistry of surfactant-functionalised polypyrrole chemical sensor systems
(Pergamon, 2011)The redox properties of electro-polymerized polypyrrole (Ppy) doped with different surfactants were studied in acid medium. It was found out that the addition of different surfactants affect the redox properties as evidenced ... -
Molecularly imprinted polymers for the analysis and removal of polychlorinated aromatic compounds in the environment: a review
(RSC, 2016)Synthetic receptors and in particular molecularly imprinted polymers (MIPs) are gaining relevance as selective sorbent materials and biomimetic recognition elements for analyzing polychlorinated aromatic compounds (PACs) ... -
Multi-walled carbon nanotubes: innovative sorbents for pre-concentration of polychlorinated biphenyls in aqueous environments
(RSC, 2015-07-21)Carbon nanotubes (CNTs) have demonstrated outstanding chemical and mechanical stability, electrical properties, and strong interactions with aromatic compounds owing to the p-electron system on the graphene sheets. Taking ... -

A Multicurve Cross-Currency LIBOR Market Model
(Hindawi, 2019)Afer the dawn of the August 2007 fnancial crisis, banks became more aware of fnancial risk leading to the appearance of nonnegligible spreads between LIBOR and OIS rates and also between LIBOR of diferent tenors.Tis ... -
Nanostructured Membranes for Water Purification
(2014)Nanoscale materials can be used to achieve wastewater purification, desalination, and inactivation of pathogenic bacteria and viruses, as well as for the adsorption and/or degradation of contaminants [1 16]. The development ... -
A New Substrate for Alkaline Phosphatase Based on Quercetin Pentaphosphate
(2014-05-22)We describe the characterization and application of quercetin pentaphosphate (QPP), a new fluorimetric substrate for the detection of alkaline phosphatase (ALP) activity. QPP exhibits major absorbance peaks at 260/ 410 ... -
Nilpotent covers of symmetric and alternating groups
(2020)We prove that the symmetric group Sn has a unique minimal cover M by maximal nilpotent subgroups, and we obtain an explicit and easily computed formula for the order of M. In addition, we prove that the order of M is ... -
Nonparametric Estimates for Conditional Quantiles of Time Series
(2014)We consider the problem of estimating the conditional quantile of a time series fYtg at time t given covariates Xt , where Xt can either exogenous variables or lagged variables of Yt . The conditional quantile is ... -
Nonparametric Estimation of the Error Functional of a Location-Scale Model
(Scienpress Ltd, 2018-10-01)Two estimators of the distribution of the error term are proposed based on nonparametric regression residuals; considering a heteroscadastic location-scale model where the mean and variance functions are smooth, and the ... -
Nonparametric Mixed Ratio Estimator for a Finite Population Total in Stratified Sampling
(2018)We propose a nonparametric regression approach to the estimation of a finite population total in model based frameworks in the case of stratified sampling. Similar work has been done, by Nadaraya and Watson (1964), Hansen ... -
A numerical analysis of unsteady inflow wind for site specific vertical axis wind turbine: A case study for Marsabit and Garissa in Kenya
(Elsevier, 2014)Most of the wind analysis studies have been conducted under steady wind conditions. The study of real unsteady wind environment, however, is still an open-ended research question. This is attributable to the existing ...
