Fabrication and characterization of poly(vinyl alcohol)-Glycerol-Spinel ferrites flexible membranes
( John Wiley and Sons Inc. , 2019 , Article)Polymer membranes of ferrites nanoparticles, glycerol, and poly(vinyl alcohol) (PVA) were fabricated using a solution casting method. Spinel ferrites nanoparticles, CuFe2O4 or ZnFe2O4, and glycerol were used as dopants to ... -
Characterization of H2S gas sensor based on CuFe2O4nanoparticles
( Elsevier Ltd , 2017 , Article)Copper ferrite (CuFe2O4) nanoparticles were prepared by the sol-gel auto-combustion method and used to construct a conductometric gas sensor in this work. The as-prepared CuFe2O4 nanoparticles were annealed at 500 °C and ... -
Adsorption and gas sensing properties of CuFe2O4 nanoparticles
( Sciendo , 2019 , Article)Spinel ferrite nanoparticles in the form CuFe2O4 were tested for gas sensing applications. Nanoparticles pressed in a disk form were used to construct conductometric gas sensors. The disk was placed between two electrical ... -
An Assorted Design for Joint Monitoring of Process Parameters: An Efficient Approach for Fuel Consumption

Single-step full-state feedback control design for nonlinear hyperbolic PDEs
( Taylor and Francis Ltd. , 2019 , Article)The present work proposes an extension of single-step formulation of full-state feedback control design to the class of distributed parameter system described by nonlinear hyperbolic partial differential equations (PDEs). ... -
Bayesian inference for linear regression under alpha-skew-normal prior [Pentaabiran Bayesian untuk Model Regresi Linear Prior Normal-Pencong-Alfa]
( Penerbit Universiti Kebangsaan Malaysia , 2019 , Article)A study on Bayesian inference for the linear regression model is carried out in the case when the prior distribution for the regression parameters is assumed to follow the alpha-skew-normal distribution. The posterior ... -
A Multivariate Homogeneously Weighted Moving Average Control Chart
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)This paper presents a multivariate homogeneously weighted moving average (MHWMA) control chart for monitoring a process mean vector. The MHWMA control chart statistic gives a specific weight to the current observation, and ... -
Robustification of CUSUM control structure for monitoring location shift of skewed distributions based on modified one-step M-estimator
( Taylor and Francis Inc. , 2019 , Article)Including three existing charts, a new approach employing a modified one-step M-estimator (MOM) with Cumulative Sum (CUSUM) control structure were evaluated and compared for their Phase II performances based on the average ... -
Total asymptotically nonexpansive mappings in uniformly convex metric spaces
( Politechnica University of Bucharest , 2019 , Article)We approximate common fixed point of a pair of total asymptotically nonexpansive mappings in the setting of a uniformly convex metric space. The proposed algorithm is computationally simpler than the existing ones in the ... -
A wavelet approach for profile monitoring of Poisson distribution with application
( Taylor and Francis Inc. , 2019 , Article)Profile monitoring is defined as the act of utilizing regression and quality control techniques to monitor the functional relationship between a response variable and one or more regressors. Most of the previous studies ... -
