for the nonlinear analysis of structures using the well known newton-raphson method, the tangent stiffness matrices of the elements must be constructed in each iteration. due to the high expense required to find the exact tangent stiffness matrices, researchers have developed novel innovations into the newton-raphson method to reduce the cost and time required by the analysis. in this paper, a ...

The subject considered in the paper is a part of work in which the main gole is creation of the tool for evaluation of patient hip joint internal loadings especially before and after arthroplasty. Internal loadings evaluation in human motion structures is still a present task in biomechanics and biomechanical engineering. The forces of muscle actuators were considered before in the aspect of co...

While building on the contingency theory, this paper proposes a conceptual framework that links five factors: a) internal forces, b) external forces, c) past web and firm performance, d) current web and firm performance, and e) e-marketing strategy in terms of the strategy defined for the 4Ws (Web-Design, Web-Promotion, Web-Price, and WebCRM). Future research is encouraged to build on this fram...

distinct target of this paper is development of 'implicit discrete element method (dem)' in three dimensions for estimating the ultimate bearing capacity of shallow foundations on layered (non-homogeneous) soils consisting of sand overlying sand or clay overlying sand and vice versa with different shear resisting parameters. in this method, shear resisting parameters and density of ea...

,2= Abstract In this paper, we address the control problem of multiple robots manipulating a load cooperatively. First we propose a controller that ensures the asymptotic convergence of the load position and the internal forces to their desired values. Next we propose an adaptive control scheme for the multi-robot system. The adaptive controller ensures the asymptotic convergence of the load po...

BACKGROUND Many disorders of the musculoskeletal system are caused by modified net joint forces resulting from individual coping movement strategies of patients suffering from neuromuscular diseases. Purpose of this work is to introduce a personalized biomechanical model which allows the calculation of individual net joint forces via inverse dynamics based on anthropometry and kinematics of the...

The aim of this work is to show the possibility of using fiber optic sensors to instrument inside parts of an artificial maxilla and measure internal tension transmitted by the orthodontic and orthopedic appliances to the dentition and the adjacent bone. Bragg gratings written in a standard optical fiber were used to monitor the maxillary teeth and a multiplexed fiber was used to monitor the su...

Research concerning forefoot strike pattern (FFS) versus rearfoot strike pattern (RFS) running has focused on the ground reaction force even though internal joint contact forces are a more direct measure of the loads responsible for injury. The main purpose of this study was to determine the internal loading of the joints for each strike pattern. A secondary purpose was to determine if converte...
