Characterization of Composite Material from the Copolymerized Polyphenolic Matrix with treated Cassava Peels Starch
(Elsevier, 2020)Conventional binders in the particleboards formulation involve use of formaldehyde resins. Epidemiologic studies show that formaldehyde is carcinogenic. Efforts to reduce formaldehyde emissions by use of scavengers has not ... -
Chloride Diffusivity in Blended Cement Made from Selected Industrial and Agrowastes
(Hindawi, 2020)This paper reports study findings on the diffusivity of chloride ions in potential blended cement. The cement, abbreviated as PCDC, was made from blending ordinary Portland cement (OPC) with dried calcium carbide residue ... -
Chloride Ingress in Chemically Activated Calcined Clay-Based Cement
(Elsevier, 2018)Chloride-laden environments pose serious durability concerns in cement based materials. This paper presents the findings of chloride ingress in chemically activated calcined Clay-Ordinary Portland Cement blended mortars. ... -
CLASSICAL CONSTRUCTION OF ANGLES IN GENERAL
(International Journal of Mathematical Archive, 2016)The construction of angles in general is a classical problem in mathematics. The early mathematicians failed to redress the problem under the stated restrictions because they did not have a bearing to approach the problem ... -
Classification of Stateless People through a Robust Nonparametric Kernel Discriminant Function
(Scientific Research Publishing, 2022-10-11)Statelessness is the absence of any Nationality. These include the Pemba, Shona, Galjeel, people of Burundi and Rwanda descent, and children born in Kenya to British Overseas Citizens after 1983. Frequently, they are not ... -
CLASSIFICATION RATES: NON-PARAMETRIC VERSES PARAMETRIC MODELS USING BINARY DATA
(Journal of Agriculture, Science and Technology, 2014)Estimations of the conditional mean and the marginal effects for particular small changes in the covariates have been of interest in financial, economics and even educational sectors. The standard approach has been to ... -
Comparing Edgeworth Expansion and Saddlepoint Approximation in Assessing the Asymptotic Normality Behavior of A Non-Parametric Estimator for Finite Population Total
(EJ-MATH, European Journal of Mathematics and Statistics, 2023-01)Abstract — Sample surveys concern themselves with drawing inferences about the population based on sample statistics. We assess the asymptotic normality behavior of a proposed nonparametric estimator for finite a population ... -
Comparison of some Panel Data Regression Model Estimators using Simulated Data
(JKUAT, 2016)This paper presents estimation of panel data regression models with individual effects. We discuss estimation techniques for both fixed and random effects panel data regression models. We derive two-stage least squares and ... -
Comparison of the ratio estimate to the local linear polynomial estimate of finite population totals
(International Journals of Multidisciplinary Research Academy, 2013)In this paper, attempt to study effects of extreme observations on two estimators of finite population total theoretically and by simulation is made. We compare the ratio estimate with the local linear polynomial estimate ... -
Control of the polarization direction of isolated attosecond pulses using inhomogeneous two-color fields
(Nature Publishing Group, 2019)We theoretically demonstrate the control of the polarization direction of isolated attosecond pulses (IAPs) with inhomogeneous two-color fields synthesized by an 800-nm fundamental pulse and a 2000- nm control pulse having ... -
Coverage properties of a neural network estimator of finite population total in high-dimensional space.
(Journal of Mathematics, 2022)The problem in nonparametric estimation of finite population total particularly when dealing with high-dimensional datasets is addressed in this paper. The coverage properties of a robust finite population total estimator ... -
The Cube Duplication Solution (A Compass-straightedge (Ruler) Construction)
(International Journal of Mathematics Trends and Technology, 2017)This paper objectively presents a provable construction of generating a length of magnitude;, as the geometrical solution for the ancient classical problem of doubling the volume of a cube. Cube duplication is believed to ... -
Deep Learning Incorporated Bu¨hlmann Credibility in the Modified Lee–Carter Mortality Model
(Hindawi, 2023-03)This research study proposes the inclusion of randomness or an error term in the modified Lee–Carter model, which improves the traditional Lee–Carter model for modeling and forecasting mortality risk for years in the ... -
Defect-induced room temperature ferromagnetic properties of the Al-doped and undoped ZnO rod-like nanostructure
(Elsevier, 2017)In this work, electron paramagnetic resonance (EPR) experiment on undoped ZnO and Al doped ZnO (AZO) nanoparticles prepared by facile sol–gel method were investigated. The effects of the Al concentration on room temperature ... -
Deriving Penalized Splines For Estimation Of Time Varying Effects In Survival Data
(International Journal of Scientific & Technology Research, 2014)The major interests of survival analysis are either to compare the failure time distribution function or to assess the effects of covariate on survival via appropriate hazards regression models. Cox’s proportional hazards ... -

A Deterministic Model Of HIV Transmission Between Two Closed Patches Incorporating The Monod Equation
(International Institute for Science, Technology and Education (IISTE), 2019-06)Among other factors, migration has significantly contributed to the spread of HIV. Recent studies have revealed that new infections occur along major transport corridors and truck-drivers have overall higher prevalence ... -
Dicarbonyl (hexamethylene-1, 3, 5, 7-tetramine-κN1)(η5-pentamethylcyclopentadienyl) iron (II) tetrafluoridoborate
(International Union of Crystallography, 2012)In the title compound, [Fe(C10H15)(C6H12N4)(CO)2]BF4, the arrangement around the FeIIatom corresponds to a three-legged piano stool. The pentamethylcyclopentadienyl (Cp*) ligand occupies three coordination ... -
