In this study, the free vibration analysis of smart vibration control (SVC) systems based on Reddy – Levinson model and modified strain gradient theory is developed. This system consist of a micro beam at middle and two magneto-electro-elastic (MEE) composite micro beams at top and bottom which connected by enclosing elastic medium and simulated by Winkler and Pasternak foundation. The effects ...

friction stir processing was applied for fabricating an aluminum alloy based hybrid nano composite reinforced with nano sized al2o3 and micro sized graphite particles. a mixture of al2o3 and graphite particles was packed into a groove with 1 mm width and 4.5 mm depth, which had been cut in 5083 aluminum plate of 10 mm thick. packed groove was subjected to friction stir processing in order to im...

background and aims. polymerization efficacy affects the properties and performance of composite resin restorations. the purpose of this study was to evaluate the effectiveness of polymerization of two micro-hybrid, two nano-hybrid and one nano-filled ormocer-based composite resins, cured by two different light-curing systems, using fourier transformation infrared (ft-ir) spectroscopy and vicke...

Small area estimation methods are used in surveys, where sample sizes too small to get reliable direct estimates of parameters some population domains. We consider design-based linear combinations and synthetic estimators propose a two-step procedure approach the optimal combination. construct mean square error estimator suitable for this any other composition that one. apply theory two composi...

background and aims. the purpose of this investigation was to assess the placement and replacement of resin-based composite restorations and related factors in a private practice in greece. materials and methods. the study included 1500 subjects, 720 males and 780 females, aged 18 to 52 years old. the clinical examination involved calculation of the number of teeth with primary caries and faile...

We propose a novel generic reputation bootstrapping framework for composite services. Multiple reputation-related indicators are considered in layer-based to implicitly reflect the of component The importance an indicator on future performance service is learned using modified Random Forest algorithm. topology-aware Deep Neural Network (fDNN) find correlations between and trained fDNN model pre...
