Identification of kinematic traits in 3D reaching Tasks with the use of a haptic Nine-Hole Peg-Board Test: Comparison between healthy people and people with Multiple Sclerosis
(Affiliation: Mechanical and Manufacturing Engineering Department, University of Cyprus, P.O. Box: 20537, Nicosia, CyprusAffiliation: Mechanical and Manufacturing Engineering Department, University of Cyprus, CyprusCorrespondence Address: Xydas, E. G.Mechanical and Manufacturing Engineering Department, University of Cyprus, P.O. Box: 20537, Nicosia, Cyprusemail: mep4ex01@ucy.ac.cy, 2008)Multiple Sclerosis (MS) is a complex neurological disease that destroys the myelin sheath of the nerves, consequently affecting the motor control ability of the person in numerous ways. Rehabilitation of the upper limb ...

Linear analysis of generalized turbulent hyperbolic flow in a rotating frame
(2007)We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame rotation rate. ...

MHD flow past a circular cylinder using the immersed boundary method
(2010)The immersed boundary method (IB hereafter) is an efficient numerical methodology for treating purely hydrodynamic flows in geometrically complicated flow-domains. Recently Grigoriadis et als. [1] proposed an extension of ...

Three dimensional flow of thixotropic materials in a channel with a sudden expansion using a phenomenological constitutive relation
(Affiliation: WPI, Worcester, United StatesCorrespondence Address: Alexandrou, Andreas N.WPI, Worcester, United States, 1996)A constitutive relation is proposed that is capable of predicting a wide range of experimental rheological behavior depending on the proper choice of the parameters. The model represents the otherwise discontinuous Bingham ...

Upper limb assessment of people with multiple sclerosis with the use of a haptic nine hole peg-board test
(Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, CyprusCorrespondence Address: Xydas, E. G.Department of Mechanical and Manufacturing Engineering, University of CyprusCyprus, 2009)In this work, a nine-hole peg-board test (NHPT) arrangement is implemented in a Virtual Environment with the use of a Haptic Interface that has the form of a small robotic arm. The Haptic NHPT is used as a mean for ...
