Measuring the fall of antihydrogen: The AEGIS experiment at CERN
( Elsevier B.V. , 2011 , Conference Paper)Considerable efforts have been made and are still being made to verify the validity of the principle of the equivalence of gravitational and inertial mass, one of the cornerstones of the classical theory of general relativity. ... -
Mechanical and thermal properties of gamma-ray irradiated polyethylene blends
( Elsevier , 2003 , Conference Paper)In this work, the results obtained by gamma-ray irradiation of polyethylene (PE) blends are presented. The blends were produced by injection molding at 220°C with different compositional ratios, i.e. 100/0, 15/85, 25/75, ... -
Metal/Metal-Oxide Nanoclusters for Gas Sensor Applications
( Hindawi Publishing Corporation , 2016 , Article Review)The development of gas sensors that are based on metal/metal-oxide nanoclusters has attracted intensive research interest in the last years. Nanoclusters are suitable candidates for gas sensor applications because of their ... -
Microscale Thermal Energy Transfer Over a Combined System of Thin Films: Analytical Approach
( Taylor and Francis Inc. , 2019 , Article)An analytical approach for the solution of the equation for phonon transport is presented for the combination thin films system. The transient phonon radiative transport model is considered and the combination of the silicon ... -
Microstructure of heat-treated steel probed by positron annihilation
(2001 , Conference Paper)Positron annihilation lifetime technique has been applied to study the microstructure change in steel after heat treatment. For this purpose, the specimens are heat treated in various manners; normalizing, annealing, ... -
Mixed EWMA-CUSUM and mixed CUSUM-EWMA modified control charts for monitoring first order autoregressive processes
( Taylor and Francis Ltd. , 2017 , Article)In practice most processes are known to produce autocorrelated observations. Autocorrelation degrades the performance of control charts by producing frequent false alarms when the process is stable or makes the charts ... -
Model for oscillations in the guidance of ions through insulating nanocapillaries
( IOP Publishing , 2011 , Conference Paper)The pre-equilibrium period of the ion guiding through insulating nanocapillaries is characterized by the production of temporary charge patches inside the capillaries. The dynamics of the charge patch creation is revealed ... -
Model predictive control of selective catalytic reduction in diesel-powered vehicles
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper proposes a method to synthesize an optimal controller for the SCR section of the diesel exhaust after-treatment system, which is based on a system model consisting of coupled hyperbolic and parabolic partial ... -
Model robust profile monitoring for the generalized linear mixed model for Phase I analysis
( John Wiley and Sons Ltd , 2020 , Conference Paper)The generalized linear mixed model (GLMM) becomes very popular in profile monitoring, especially when the production processes follow nonnormal distribution. In most of the real-life applications in industry, medicine, ... -
Model-based optimal boundary control of selective catalytic reduction in diesel-powered vehicles
( Elsevier Ltd , 2018 , Article)This paper is devoted to design a model-based boundary optimal controller for selective catalytic reduction system. The mathematical model consists of coupled parabolic-hyperbolic PDEs with an ODE. The main objective is ... -
Modeling the population-level impact of treatment on COVID-19 disease and SARS-CoV-2 transmission
( Elsevier , 2022 , Article)Different COVID-19 treatment candidates are under development, and some are becoming available including two promising drugs from Merck and Pfizer. This study provides conceptual frameworks for the effects of three types ... -
The modified homotopy perturbation method for solving strongly nonlinear oscillators
( Elsevier , 2009 , Article)In this paper we propose a reliable algorithm for the solution of nonlinear oscillators. Our algorithm is based upon the homotopy perturbation method (HPM), Laplace transforms, and Padé approximants. This modified homotopy ... -
Modified Profile Likelihood Estimation in the Lomax Distribution
( Horizon Research Publishing , 2022 , Article)In this paper, we consider improving maximum likelihood inference for the scale parameter of the Lomax distribution. The improvement is based on using modifications to the maximum likelihood estimator based on the ... -
Molybdenum oxide reinforced polyvinyl alcohol composite as high-performance dielectric material for flexible electronics
( Springer , 2023 , Article)Polymer dielectrics are highlighted as capable energy storing materials due to their better dielectric strength and supreme versatility compared to inorganic ceramic dielectrics in sophisticated electronics and pulsed power ... -
Moment invariants for multi-component shapes with applications to leaf classification
( Elsevier B.V. , 2017 , Article)In this paper we introduce seven new invariants for multi-component shapes, and apply them to the leaf classification problem. One of the new invariants is an area based analogue of the already known boundary based anisotropy ... -
Monitoring Coefficient of Variation Using Progressive Mean Technique
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Control charts are mostly used for the monitoring of process mean and dispersion. In cases, when the process standard deviation is proportional to the mean, it is recommended to use control charts based on coefficient of ... -
Monitoring multivariate coefficient of variation for high-dimensional processes
( John Wiley and Sons Ltd , 2022 , Article)Multivariate coefficient of variation (MCV) charts are effective tools for monitoring process relative variability. They are developed on the assumption that the process subgroup size available for monitoring the MCV ... -
