the effect of intrusive orthodontic force on dental pulp of adults versus adolescents
background: there is no conclusive evidence on the effect of orthodontic force application on dental pulp tissue. the aim of this study was to compare early and delayed histological effects of intrusive forces on dental pulp of adolescents and adults. materials and methods: patients referred to the department of orthodontics of mashhad university of medical sciences participated in this study. ...
متن کاملWeak Force Measurement in Bistable Optomechanical System
One of the main milestones in the study of opto-mechanical system is to increase the sensitivity of weak forces measurement up to the standard quantum limit. We have studied the detection of weak force under a bistable condition in red detuned regime. In this case, dynamics of the system behaves asymptotically similar to stationary state and applying external force affects phase and fluctuation...
متن کاملNON-INTRUSIVE PIPE FLOW MEASUREMENT BY CROSS CORRELATION OF TEMPERATURE VARlATIONS
The flow of water in pipes has been measured by placing thermistors at two points along a pipe's surface and measuring the temperature variations (on the order of 30 sec duration) as the fluid passes. Cross correlation of the two sets of temperature versus time data is used to determine the time delay from the upstream to the downstream sensor. The distance between the two sensors is then used ...
متن کاملNon-Intrusive Action Symmetry Measurement for Dementia and Rehabilitation
The purpose of this work is to quantify the symmetry in human actions, which is a common objective in medical research. To this end, a novel non-intrusive method for quantifying action symmetry in the frequency domain is proposed. Reflectional symmetry is estimated over time and a new metric is proposed based on dynamic symmetry warping distance. The proposed method can be utilised to provide q...
