The elastic properties of homogeneous, linear-elastic materials can be identified using resonant vibration analysis. Several sources of uncertainty contribute to the combined uncertainty of the measured values. This paper presents a method to handle uncertainty budgets in vibration based mixed numerical-experimental identification techniques. The presented method is evaluated with two numerical...

Chitosan-coated magnetic nanoparticles (CMNP) were prepared in one-step by precipitation in a high-aqueous phase content reverse microemulsion in the presence of chitosan. The high-aqueous phase concentration led to productivities close to 0.49 g CMNP/100 g microemulsion; much higher than those characteristic of precipitation in reverse microemulsions for preparing magnetic nanoparticles. The o...

Titanium-based coated electrodes are considered to be a substitute for Pb-based anodes because of their lower weights and energy consumption; however, properties service lives affected by the matrix structure. Herein, metal oxide coating was prepared via thermal oxidation decomposition 5 μm-porous titanium plate. The scanning electron microscope (SEM) showed that on porous plate strengthened in...

An anticorrosion layer is a significant component that prevents the corrosion process in materials. In this work, nanofiber of poly (methyl methacrylate) composited with few-layer-graphene was prepared as an layer. electrospinning applied to prepare composite on metal substrate at various concentrations few-layer graphene. The physical properties were investigated field-emission scanning electr...

A single-chip white light LED is commonly modeled by considering the phosphor coating as a homogeneous Lambertian light source. However, this approach leads to an incorrect optical simulation of phosphor-coated multi-chip LEDs due to the presence of a previously unreported spatial distribution of emission spots across the phosphor layer. We introduce "weighting" factors based on position-depend...

Background and Objectives: Increased environmental concerns about synthetic packaging have promoted developments of novel, environmentally-friendly edible films. In the present study, the quality parameters of chicken egg coated with pectin or pectin incorporated cinnamon hydrosol was assessed. Materials and Methods: Egg chicken were coated with pectin and pectin prepared with cinnamon hydroso...

The objective of this study was to analyze gelatins extracted from tilapia (Oreochromis niloticus) skin and evaluate its effect as a coating on fish fillets the same species. Four gelatin extractions skins were prepared in acidic alkaline conditions, followed by filtration freeze drying. samples analyzed for moisture, lipids, ash, proteins, color parameters, viscosity, spectrophotometry coating...

The coupling between plate motions and mantle convection is investigated using a fully dynamic numerical model consisting of a thin non-Newtonian layer which is dynamically coupled to a thick Newtonian viscous layer. The non-Newtonian layer has a simple power-law rheology characterized by power-law index n and stiffness constant pp. A systematic investigation of steady, single cell configuratio...
