background: parkinson's disease as a progressive disorder of the nervous system leads to the disability of postural control system. objectives: in the present study the effects of pilates exercises on functional balance in patients with parkinson's was investigated. materials and methods: this control trial included 30 patients with idiopathic parkinson's disease who were selecte...

In this paper, we present an approach to the bootstrapping learning of a page segmentation model. The idea evolves from attempts to segment dictionaries that often have a consistent page structure, and is extended to the segmentation of more general structured documents. In cases of highly regular structure, the layout can be learned from examples of only a few pages. The system is first traine...

A forbidden-region virtual fixture (FRVF) is a constraint, implemented in software, that keeps the slave manipulator of a master/slave telemanipulation system from entering into a forbidden region of the workspace. In this paper, we consider the problem of unstable vibrations of the slave against the FRVF for a general class of telemanipulator control architectures. The master and slave equilib...

Purpose: Core stability and leg stiffness are two determinant mechanisms in athletic performance and risk injury. This study aimed to investigate the gender differences and relationship of these two factors in athletes. Methods: In this cross-sectional study, core stability and leg stiffness of 12 male and 12 female Iranian squash players at national level were examined utilizing McGill’...

A new stability criterion on Nichols chart is presented. It provides an alternative graphical method for stability analysis on Nichols chart. Furthermore this result can be used to test the stability of the new nominal closed-loop system arising in QFT controller design method for non-minimum phase and unstable plants, which is diicult to test with the existing stability criterion.
