introduction: knee joint has the highest percentage of injuries among lower extremity joints especially in athletes and people with high activity levels. therefore, analyzing of knee movements has an important area of research in the bioengineering and rehabilitation fields. sharif human movement instrumentation system (sharif-hmis) is a new inertial sensor designed for movement analysis. the p...

apical extrusion of debris and irrigants during cleaning and shaping of the root canal is one of the main causes of periapical inflammation and postoperative flare-ups. the purpose of this study was to quantitatively measure the amount of debris and irrigants extruded apically in single rooted canals using two reciprocating and one rotary single file nickel-titanium instrumentation systems.sixt...

AIM Many studies are available in the literature on posterior spinal instrumentation, though the use of a rod and a plate is still controversial in the literature. In this study, a finite element analysis of the strength and superiority of modular rigid plate and rod systems, which are used in the lower lumbar region, in comparison with each other was used. MATERIAL AND METHODS A Ti6Al4V (Gra...

We performed a biomechanical study on human cadaver spines to determine the effect of three different interbody cage designs, with and without posterior instrumentation, on the three-dimensional flexibility of the spine. Six lumbar functional spinal units for each cage type were subjected to multidirectional flexibility testing in four different configurations: intact, with interbody cages from...

This paper describes the implementation of a platform based on reconfigurable architecture and concepts of virtual instrumentation applied to the study of the hands-free driving problem. The novelty of this approach is the use of both reconfigurable systems (for developing the car’s controller) and virtual instrumentation issues for developing a high-level abstraction testing and simulation env...
