This paper demonstrates the deterministic errors in thermocouple measurements, or bias, through numerical simulation and illustrates the impact of these erroneous measurements on inverse heat conduction problem solutions. The case of molten metal solidifying through cooling in a sand mold is considered. Artificial data for the sand surface temperature and at two different locations below the sa...

In this paper, the Bayesian analysis of inverse Rayleigh distribution has been considered under singly and doubly type II censored data. The Bayes estimators and corresponding risks have been derived under the assumption of non-informative priors and using symmetric and asymmetric loss functions. The credible intervals have been constructed under the assumption of non-informat ive prio rs. The ...

Abstract: The legged robot can only walk very similar to human walking pattern. Therefore, many robots have been researched and developed in recent years. However, the biped robots still have many issues for the natural human walking in terms of the redundant degree of freedom, complexity of the kinematics, and stability. In this paper, we have described our biped robot modeling in the forward ...

A two parameter generalization of the Inverse Rayleigh distribution capable of modeling bathtub hazard rate function is defined and studied with application to reliability data. A comprehensive account of the mathematical properties of the modified Inverse Rayleigh distribution including estimation and simulation with its reliability behavior are discussed. An application is presented to illust...

Efficient drive cycle simulation of longitudinal vehicle propulsion models is an important aid for design and analysis of power trains. Tools on the market today mainly use two different methods for such simulations, forward dynamic or quasi-static inverse simulation. Here known theory for stable inversion of non linear systems is used in order to combine the fast simulation times of the quasi-...

A recently developed inverse scattering algorithm [A. J. Devaney and M. Dennison, Inverse Probl., 19, 855 (2003) and M. Dennison and A. J. Devaney, Inverse Probl., 20, 1307 (2004)] is described and applied in a computer simulation study of optical diffraction tomography (ODT). The new algorithm is superior to standard ODT reconstruction algorithms, such as the filtered backpropagation algorithm...

A simulational model of 6 dof Stewart platform type parallel manipulator is presented. The manipulator is driven by electrohydraulic actuators. A novel invariant error dynamics controller is used. The developed control scheme employs the dynamic and hydraulic model of the system. The manipulator model consists of the rigid body equations of motion and the hydraulic dynamics of the main elements...

The emergence of the theory of dynamic neural computing has made it possible to develop neural learning and adaptive schemes that can be used to obtain feasible solutions to complex control problems, such as inverse kinematic control for robotic systems. In this paper, such a neural learning scheme using a multilayered dynamic neural network (MDNN) is proposed. The basic dynamic computing eleme...

119004-7272 IJMME-IJENS © August 2011 IJENS I J E N S  Abstract—In this paper, diagonal walking strategy on inclined floor is proposed. In conventional methods, bipedal robots walking on inclined floor are solved only in straight direction. When a biped walks on flat floor, the pelvis orientation is always parallel with the floor surface. However, walking on inclined floor will make the robot ...

A large-scale combined legged and wheeled vehicle with anthropomorphic legs is presented. This concept combines the advantages of a walking machine with the stability of a wheeled vehicle. The leg utilises a spherical hip joint, a revolute knee joint and a passively pivoting foot. Due to the size of the system linear hydraulic actuators are used, and thus kinematic loops are created in the mech...
