Conditional Volatility Estimation by Conditional Quantile Autoregression
(HIKARI Ltd, 2014)This paper considers the problem of estimating conditional volatility function using conditional quantile autoregression function. We estimate the interquantile autoregression range and the conditional volatility function ... -
Conflict resolution using statistical approach
(Academic Journals, 2010)Conflict can be described as a condition in which actions of one person prevent or compel some outcome at the resistance of the other. Quite often this can be seen as “two or more competing, often incompatible, responses ... -
Consistency of the Model Order Change-Point Estimator for GARCH Models
(Scientific Research Publishing Inc., 2018)GARCH models have been commonly used to capture volatility dynamics in financial time series. A key assumption utilized is that the series is stationary as this allows for model identifiability. This however violates the ... -
Control volume method for modelling slightly compressible flow reservoirs
(2015)Numerical simulation is widely used for predicting reservoir behavior and forecasting its performance. In this paper numerical modeling isperformed to simulatesingle phase flow in oil reservoir in horizontal ... -
Crank Nicolson Approach for the Valuation of the Barrier Options
(Research India Publications, 2018)Barrier options are considered to be cheaper than the standard options as they provide lower premiums which make them to be attractive to hedgers in the financial market. In this article, the numerical procedure for the ... -
Cross-Diffusion Effect on Mixed Convective Fluid Flow through Horizontal Annulus
(Mathematical Theory and Modeling, 2014)The unsteady mixed convective fluid flow through an annulus filled with a fluid-saturated porous medium is numerically investigated in this study in the presence of Cross-Diffusion effect and constant Heat Source. The flow ... -
Current and Emerging Technologies for the Characterization of Nanomaterials
(American Chemical Society, 2014-05-20)This paper provides a survey of conventional and emerging techniques that are available for characterizing engineered nanoparticles in complex matrices. Techniques that were considered include microscopy (TEM, SEM, HRTEM, ... -
Cycle indices of PGL(2,q) acting on the cosets of its subgroups
(International Journal of Scientific Research and Innovative Technology, 2017)In this paper, we mainly investigate the action of 𝑃𝐺𝐿 2,𝑞 on the cosets some of its subgroups namely; 𝐶𝑞−1,𝐶𝑞+1and 𝑃 𝑞. Corresponding to each action the disjoint cycle structures and cycle index formulas is ... -
Degradation characteristics of metribuzin in soils within the Nzoia River Drainage Basin, Kenya
(Taylor & Francis, 2016)Metribuzin, a triazinone herbicide, is heavily used within the expansive Nzoia River Drainage Basin in Kenya for the optimization of sugarcane yields. For field experiments, soils were spiked with metribuzin and amended ... -
Demonstration of Raman-based, dispersion-managed VCSEL technology for fibre-to-the-hut application
(Elsevier, 2017-03)For the first time, we experimentally investigate the use of vertical cavity surface emitting lasers (VCSELs) in the fibre-to-the-home (FTTH) flavour for Africa, known as fibre-to-the-hut. Fibre-to-the-hut is a VCSEL ... -
Determinants of Mobile Money Remittance in East Africa
(2017)Globally, remittances represent an important flow of international financial resources. In the East African trading bloc, the dynamic population movements between countries has led to widespread distribution of population ... -
Determination of Anthracene on Ag-Au Alloy Nanoparticles/Overoxidized-Polypyrrole Composite Modified Glassy Carbon Electrodes
(Molecular Diversity Preservation International, 2010)A novel electrochemical sensor for the detection of anthracene was prepared by modifying a glassy carbon electrode (GCE) with over-oxidized polypyrrole (PPyox) and Ag-Au (1:3) bimetallic nanoparticles (Ag-AuNPs). The ... -
Determination of serum isometamidium levels in sheep and goats under field conditions using isometamidium-ELISA
(2000)Twenty eight sheep and 28 goats were treated with isometamidium chloride (Samorin®, hone Merieux, Lyon, France) at a dose of 1 mg/kg body weight (bw) by intramuscular injection. All the animals were grazed in a tsetse-infested ... -
Discussion on Generalized Modified Inverse Rayleigh
(2018-01-01)In this paper, a generalization of the modified inverse Rayleigh distribution called the new exponentiated generalized modified inverse Rayleigh distribution is proposed and studied. Various sub-models of the new distribution ... -
Dissipation Behavior of Malathion and DimethoateResidues from the Soil and Their Uptake by Garden Pea(Pisum sativum)
(Environmemental Contamination and Toxicology, 2000)The contamination of soil by pesticide chemicals can occur through direct application to control some inhabiting insect pests of a variety of economic plants while indirect avenues can occur through aerial ... -
