This study was conducted to develop a detailed, nonlinear three-dimensional geometrically and mechanically accurate finite-element model of the human lower cervical spine using a high-definition digitizer. This direct digitizing process also offers an additional method in the development of the finite-element model for the human cervical spine. The biomechanical response of the finite-element m...
The aim of this study was to compare sensitivity, specificity, accuracy and positive and negative predictive value for high-resolution ultrasonography (HR-US) in diagnosing degenerative changes, effusion and disk displacement using magnetic resonance imaging (MRI) as a reference. Over a period of 6 months, 100 patients with TMJ disorders (200 TMJs) were investigated by an experienced radiologis...
In this work, we have investigated the design, fabrication and testing of ZnO-on-SOI fourth-order contour mode disk resonators for mass sensing applications. This study aims to unveil the possibility for real-time practical mass sensing applications by using high-Q ZnO-on-SOI contour-mode resonators while taking into account their unique modal characteristics. Through focused ion beam (FIB) dir...
In this paper, a feedback control mechanism and its optimization for rotating disk vibration/flutter via changes of air-coupled pressure generated using piezoelectric patch actuators are studied. A thin disk rotates in an enclosure, which is equipped with a feedback control loop consisting of a micro-sensor, a signal processor, a power amplifier, and several piezoelectric (PZT) actuator patches...
Abstract Using the method of singular integral equations, elastic-plastic problem for cracked Brazilian disk was solved. Based on Dugdale model and deformation fracture criterion, relationships between critical load, notch tip opening displacement length plastic strips were established. Also, comparison present solution finite domain known obtained semi-infinite in elastic plane performed.
Analysis of transient thermoelastic stress distribution a thin circular sector disk with time-fractional derivative order α is proposed. The Neumann types boundary conditions are used and the integral transform method Caputo fractional to obtain analytical solutions temperature, displacement, stresses. Numerical values stresses computed for an Aluminum (pure) material presented graphically help...
We consider in this work general curved rods with a circular cross-section of radius δ. Our aim is to study the asymptotic behaviour of such rods as δ→0, in the framework of the linear elasticity according to the unfolding method. It consists in giving some decompositions of the displacements of such rods, and then in passing to the limit in a fixed domain. A first decomposition concerns the el...
