Real-time magnetic resonance imaging (rtMRI) provides information about the dynamic shaping of the vocal tract during speech production.1 We develop a dynamical system in the framework of Task Dynamics2 which controls vocal tract constrictions and induces deformation of the air-tissue boundary. The system parameterizes the air-tissue boundary through factor analysis of rtMRI videos and characte...

We introduce and evaluate several new models of network growth. Our models are extensions of the FKP model, modifying and improving it in various dimensions. In all these models nodes arrive one by one, and each node is connected to previous nodes by optimizing a trade-off between a geometric objective (“last mile cost”) and a topological objective (“position in the network”). Our new models di...

The identification and authentication are done by passwords, pin number, which is easily cracked by others. Biometrics is a powerful and unique tool based on the functional and behavioral characteristics of the human beings in order to prove their authentication. One of the current trends in biometric human identification is the development of new developing modalities. Knuckle biometrics is on...

In this paper, kinematic modeling and singularity analysis of a three DOF redundant parallel manipulator has been elaborated in detail. It is known, that on the contrary to series manipulators, the forward kinematic map of parallel manipulators involves highly coupled nonlinear equations, whose closed-form solution derivation is a real challenge. This issue is of great importance noting that th...

[Purpose] The aim of this study was to investigate the effect of kinesio taping (KT) on the kinematics of the lumbo-pelvic-hip complex during forward bending by individuals with reduced hamstring extensibility. [Subjects] Eighteen males with reduced hamstring extensibility were randomly assigned to one of two groups:, the hamstring KT group (n=9), or the sham KT group (n=9). [Methods] The kinem...

In this paper, a quasi-closed solution method is presented to solve the forward kinematics of a three DOF actuator redundant hydraulic parallel manipulator. It is shown, that on the contrary to series manipulators, the forward kinematic map of the parallel manipulators involves highly coupled nonlinear equations, which are almost impossible to solve analytically. The proposed method uses a comb...

This paper investigates the use of genetic algorithm to optimize poses selection to improve kinematic calibration for manipulator. Genetic algorithm is used to determine the optimal poses while iterative least square algorithm is used to calibrate the kinematics model of the manipulator. Observability index are used to evaluate the optimality of the set of poses. The fitness function of genetic...

Abstract—Robot kinematics and dynamics is the basis of robotics research, providing the important basis for robot path planning and motion control etc. The paper focuses on the six degrees of freedom industrial robot which is developed independently, adopts the D-H method to do the forward kinematics analysis and inverse kinematics analysis for robot, establishes the kinematics model, and uses ...

Using the conformal invariance the leading-log evolution of the off-forward structure function is reduced to the forward evolution described by the conventional DGLAP equation. The method relies on the fact that the anomalous dimensions of the Gegenbauer moments of the off-forward distribution are independent on the asymmetry, or skewedness, parameter and equal to the DGLAP ones. The integral k...

This paper presents analytical solutions for the forward displacement kinematics of the “31-12” fully parallel manipulator design. In this design, three points in the base platform are linked to one single point in the top platform, while two of the remaining top platform points are linked to a single point in the base. Neither the base nor the top platforms of the manipulator have to be planar...
