Abstract: A method of calculation is presented for the flow characteristics of a two-dimensional supercavitating cascade with finite-length cavities and with an arbitrary pressure distribution. The principle ...

Abstract: A nonlinear method of finding two-dimensional supercavitating sections in a cascade is developed. The load distribution is taken from linear theory for low drag super-cavitating foils in a ...

Abstract: Two new designs for gravity compensated modular robotic systems are presented and analyzed. The gravity compensation relies on using zerofreelength springs approximated by a cable and pulley system. Simple yet powerful ...

Abstract: Accurate position sensing is important for state estimation and control in robotics. Reliable and accurate position sensors are usually expensive and difficult to customize. Incorporating them into systems that have very ...

Abstract: We treat the question of position and force control of a three-axis elastic robotic system on a constraint surface based on nonlinear inversion of an input-output map and linear feedback ...

Abstract: This paper presents a new approach to end-point trajectory control of flexible macro-micro manipulator based on nonlinear inversion and predictive control techniques. In this approach, precise ...

Abstract: Complex responses observed in an experimental, nonlinear, moored structural system subjected to nearly periodic wave excitations are examined and compared to the simulations of a newly proposed ...

Abstract: An independent-flow-field (IFF) model selected in this study to investigate the nonlinear response behavior of a medium-scale, experimental, submerged, moored structure is validated via parametric ...

Abstract: A quadrilateral plane element for analysis of spatial structures is often formulated by combining a plane stress (membrane) element with two translational inplane degrees of freedom at each corner to a plate bending element ...
