In the present paper, an attempt has been made to carry out kinematic and dynamic analysis of a six-legged robot. A three-revolute (3R) kinematic chain has been chosen for each leg mechanism in order to mimic the leg structure of an insect. Denavit–Hartenberg (D-H) conventions are used to perform kinematic analysis of the six-legged robot. The direct and inverse kinematic analysis for each leg ...

In the present work, the influences of temperature, solvent concentration and ultrasonic irradiation time were numerically analyzed on viscosity reduction of residue fuel oil (RFO). Ultrasonic irradiation was applied at power of 280 W and low frequency of 24 kHz. The main feature of this research is prediction and optimization of the kinematic viscosity data. The measured results of eighty-four...

Most knowledge management (KM) projects aim at creating a knowledge base system in which all corporate knowledge is organized according to a single, supposedly shared and objective classi cation. The underlying assumption is that knowledge can be made objective re ning it of all its subjective, contextual, and social aspects. However, a lot of work in disciplines like arti cial intelligence, co...

The Distributed Knowledge Management (DKM) approach tries to overcome problems deriving from a typical outcome of traditional Knowledge Management (KM) solutions: the creation of a unique conceptualization of corporate knowledge (e.g. an ontology or a unique system of classification) which does not allow autonomy of organizational units and the coexistence of different conceptual schemas (e.g. ...

Precise teleoperation of deztrous robotic hands b y hand masters requires an accurate human hand model. A kinematic model of a human index finger is developed as an example for human hand modeling. The parameters of the model are determined b y open-loop kinematic calibration. Singular value decomposition is used as a tool for analyzing the kinematic model and the identification process. Accura...

Mirror-symmetrical bimanual movement is more stable than parallel bimanual movement. This is well established at the kinematic level. We used functional MRI (fMRI) to evaluate the neural substrates of the stability of mirror-symmetrical bimanual movement. Right-handed participants (n=17) rotated disks with their index fingers bimanually, both in mirror-symmetrical and asymmetrical parallel mode...
