Temporomandibular disorders are relatively common disturbances in the world and Vietnam. The Diagnostic Criteria for Temporomandibular Disorders suggested by Schiffman in 2014 is a frequently used diagnostic system to classify temporomandibular disorders into subtypes, toward therapeutics purposes. Objectives: (1) To investigate clinical features of temporomandibular disorders in adult patients. (2) To classify temporomandibular disorders using the Diagnostic Criteria for Temporomandibular Disorders of Schiffman.

This research aims to numerically simulate the performance of the tested PC utility poles using Applied Element Method (AEM) and Finite Element Method (FEM). The simulation results demonstrate that both AEM and FEM effectively reproduce the load-displacement relationship observed in the test. Additionally, this study discusses the material models employed in simulations, considering the limitations inherent in numerical modeling.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).

The thesis contributes to the economics literature by providing a theoretical and empirical investigation of the effects of changes in the relative size of government on Australian economic performance. The theoretical literature indicates that an expansion in government size is likely to induce adverse effects upon economic growth for a host of reasons.

Analytical expressions for the anharmonic effective potential, local force constant, Displacement-displacement Correlation Function (DCF) CR and Debye-Waller factor described by the Mean Square Relative Displacement (MSRD) σ2 and by the Mean Square Displacement (MSD) u2of bcc crystals in the X-ray Absorption Fine Structure (XAFS) have been derived. The effective interatomic potential of the system has been considered by taking into account the influences of nearest atomic neighbors, and it contains the Morse potential characterizing the interaction of each pair of atoms.

For this study, different volume fraction (vol.%) of particulate alumina (Al2O3) reinforced aluminium alloy (Al 6061) with 5 vol.%, 15 vol.% and 25 vol.% are produced by powder metallurgy method. These samples were subjected to biaxial stresses in order to investigate the behaviour of the metal matrix composites (MMCs). Microstructure analysis on the individual sample before and after loading was performed under scanning electron microscopy. The small particles of 2 µm in size have exhibited strong interfacial bonding with the matrix.

We have investigated the thermodynamic properties of the cubic zirconia ZrO2 using the statistical moment method in the statistical physics. The free energy, thermal lattice expansion coefficient, specific heats at the constant volume and those at the constant pressure, CV and CP , are derived in closed analytic forms in terms of the power moments of the atomic displacements.

In this paper, an analytical solution for whirling analysis of axial-loaded Timoshenko rotor is presented and corresponding basic functions are derived. The set of governing equations for whirling analysis of the rotor consists of four coupled partial differential equations; using complex displacements, these equations can be reduced to two coupled partial differential equations.

File processing is the process of creating, storing and accessing content of files. File processing can be used in opening saved files for read only purpose. It can be used to save a new file or displace the existing one. Through file processing you can make new files and save the existing files. You can also modify files through this process.
