Knowledge of the movements of the whole spine and lumbosacral joint is important for evaluating clinical pathologic conditions that may potentially produce unstable situations in human body movements. At present there are few studies that report systematic three-dimensional (3D) movement and force analysis of the whole spine. In this paper, a fully discretized bio-fidelity 3D musculoskeletal simulation model for biomechanical (kinematic) analysis of scoliosis for a patient with right thoracolumbar scoliosis is presented. It is important to note that this method can be used for modeling various

Abstract:
&lt;p&gt;The use of lead rubber bearing becomes popular in moderate to high seismic zones in the case of highway bridges. It has the benefits to reduce the demand significantly compared to typical structures, for which seismic restrainers are considered. LRB may have a significant impact on the quantities, on the construction and also on the maintenance.&lt;/p&gt;&lt;p&gt;To be efficient, the LRB yielding force should be small enough to generate large damping in case of seismic event. For railway project such as Jakarta LRT, this yielding force should also be calibrated smartly in order to avo
