in this paper, a bayesian approach is proposed for shift point detection in an inverse gaussian distribution. in this study, the mean parameter of inverse gaussian distribution is assumed to be constant and shift points in shape parameter is considered. first the posterior distribution of shape parameter is obtained. then the bayes estimators are derived under a class of priors and using variou...

This paper presents a novel method to solve the inverse kinematics of redundant manipulators with active Spherical ball joint. The workspace density function is built combining the Fourier transform, convolution theorem and particular form of the workspace density of a single link, which can accurately generate the size of workspace. The approach of inverse kinematics selects a solution from am...

Flexible needle insertion into viscoelastic tissue is modeled in this paper with a linear beam supported by virtual springs. Using this simplified model, the forward and inverse kinematics of the needle is solved analytically, providing a way for simulation and path planning in real-time. Using the inverse kinematics, the required needle basis trajectory can be computed for any desired needle t...

Stochastic simulation of facies or geologic units is important before the assignment of continuous rock properties. Sequential indicator simulation (SIS) remains a reasonable approach when there are no clear genetic shapes that could be put into object-based modeling. Constraining SIS to soft secondary data coming from geological interpretation or geophysical measurements is important. There ar...

This paper aims at describing a new method to simulate the locomotion of hemiplegic subjects. To this end, we propose to use inverse kinematics in order to make the feet follow a trajectory with respect to the root frame linked to the pelvis. The 11 degrees of freedom are then retrieved by inversing the kinematic function while taking other constraints into account. These constraints, termed se...

In this paper, the simple geometric kinematics of a three-wheeled holonomic mobile robot is proposed. Wheel architecture is developed for the holonomic mobile platform in order to provide omni-directional motions by three individually driven and steered wheels. Three types of basic motions are proposed for the path generation of the developed mobile robot. All paths of the mobile robot can be a...

In contrast to most scientific disciplines, sports science research has been characterized by comparatively little effort investment in the development of relevant phenomenological models. Scarcer yet is the application of said models in practice. We present a framework which allows resistance training practitioners to employ a recently proposed neuromuscular model in actual training program de...

mathematical simulation of flow toward drains is an important and indispensable stage in drainage design and management. many related models have been developed, but most of them simulate the saturated flow toward drains without a due consideration of the unsaturated zone. in this study, the two dimensional differential equation governing saturated and unsaturated flow in porous media is numeri...

With extended autonomous capability planetary rovers will be able to carry out more exploration. This paper presents a method of control that provides such autonomy. This controller is based on Inverse Simulation, which considers the path to be taken and the dynamics of the rover. The principle of Inverse Simulation is that the time history for the desired trajectory is used as an input to the ...

Approximate higher order polynomial inversion of the top-hat filter is developed with which the turbulent stress tensor in Large-Eddy Simulation can be consistently represented using the filtered field. Generalized (mixed) similarity models are proposed which improved the agreement with the kinetic energy transfer to small scales. These similarity models are analyzed for random periodic signals...
