Electrochemical detection of dioctyl phthalate using molecularly imprinted polymer modified screen-printed electrodes
(Elsevier, 2022)We report the investigation of electropolymerised molecularly imprinted polymers (E-MIPs) for the determination of dioctyl phthalate (DOP). Low-cost and eco-friendly commercially available screenprinted electrodes (SPEs) ... -
Electrochromism in Self-Assembled Porous Thin Films of Hexagonal Tungsten Trioxide Microspheres Prepared by Aqueous Chemical Growth
(International Journal of ELECTROCHEMICAL SCIENCE, 2014-03)WO3 thin films were grown by self-assembly, at 80-90 ˚C, on un-seeded conductive SnO2:F-glass through the method of Aqueous Chemical Growth (ACG). The thin films produced contained urchin-like microspheres of WO3, 1-2 μm ... -
Electronics of Conjugated Polymers (I): Polyaniline
(International Journal of ELECTROCHEMICAL SCIENCE, 2012-12)Conducting polymers have elicited much interest among researchers because of their reasonably good conductivity, stability, ease of preparation, affordability and redox properties compared to other organic compounds. In ... -
Elliptic Curve Digital Signatures and Their Application in the Bitcoin Crypto-currency Transactions
(2017-10)The Elliptic Curve Digital Signature Algorithm (ECDSA), defines a technique for generating and validating digital signatures. We start by reviewing the mathematics behind the Digital Signature Algorithm (DSA) and its ... -
Empirical and numerical analysis of small wind turbine aerodynamic performance at a plateau terrain in Kenya
(2016)Kenya's energy depends on fossil fuels and the country is yet to embrace alternative sources that are environmentally friendly. In this paper, empirical and computational approaches are presented to investigate aerodynamic ... -
Enhanced hexazinone degradation by a Bacillus species and Staphylococcus species isolated from pineapple and sugarcane cultivated soils in Kenya
(Environmental Chemistry and Ecotoxicology, 2022)In this work, hexazinone-degrading bacterial strains from Kenyan tropical soils with long term application history were isolated and identified. Non-sterile soils from sugarcane and pineapple cultivated fields with over ... -
Environmental Applications of Poly(amic acid)-based Nanomaterials

Estimating Dependence Structure and Risk of Financial Market Crash
(Canadian Center of Science and Education, 2016-10)In this paper, we estimate the dependence structure between international stock markets using copulas. Different relationships that exist in normal and extreme periods were estimated using Clayton copula. The Inference ... -
Estimation of Conditional Weighted Expected Shortfall under Adjusted Extreme Quantile Autoregression
(Scientific Research Publishing Inc., 2021-07-14)In this paper, we present an estimator that improves the well-calibrated coherent risk measure: expected shortfall by restructuring its functional form to incorporate dynamic weights on extreme conditional quantiles used ... -
Estimation of Critical Streamflow Discharge Level Using Nonparametric Quantile Regression Model
(2016)Various parametric models have been designed to analyze volatility in river flow time series data. For maximum likelihood estimation these parametric methods assumes a known conditional distribution. This paper considers ... -
ESTIMATION OF EXTREME VALUE AT RISK IN RWANDA EXCHANGE RATE
(European Centre for Research Training and Development UK, 2014-12)Estimating the probability of rare and extreme events is a crucial issue in the risk estimation of exchange rate returns. Extreme Value Theory (EVT) is a well-developed theory in the field of probability that studies the ... -
Estimation of Risk in Rwanda Exchange Rate
(2014)Generalized Autoregressive Conditional Heteroskedasticity (GARCH) approach was applied to Rwanda Exchange rate returns to estimating current volatility. We fitted autoregressive (AR) model with GARCH errors to the daily ... -
Estimation of T- period’s ahead extreme quantile autoregression function
(African Journal of Mathematics and Computer Science Research, 2010)This paper considers the estimation of extreme quantile autoregression function by using a parametric model. We combine direct estimation of quantiles in the middle region with that of extreme parts using the model and ... -

Experimental and numerical study of turbulence effect on aerodynamic performance of a small-scale vertical axis wind turbine
(2016)The suitability of vertical axis wind turbines (VAWTs) in harnessing energy within a complex wind environment has increased their renewed interest. However, there still exists a huge knowledge gap about the aerodynamic ... -
Experimental and Theoretical Characterization of Metal Complexation with Humic Acid
(2016)This study investigated the bonding of calcium and magnesium to specific sites in humic acid as a function of pH, temperature, and trace metal concentrations. Other metals were investigated but not in detail. Using a ... -
Exploring the trophic structure in organically fertilized and feed-driven tilapia culture environments using multivariate analyses
(AquacultureResearch, 2006)Reports of similar yields in manure and feed-driven tilapia culture environments raise questions on food utilization in these environments. The possibility that similar production rates are because of utilization of di¡erent ... -
