Kinematic position analysis is the first step in creating a complete mathematical model of the new manipulator architecture. This analysis will begin by developing a general descriptive model that characterizes the kinematic geometry of the device. From this geometric model, a mathematical function relating the input-to-output position parameters will be formed. The goal of this function is to ...

In this paper, faults, one of the most important causes geohazards, were investigated from a kinematic and geometric viewpoint in northern part Sistan suture zone (SSZ), which serves as boundary between Afghan Lut blocks. Furthermore, field evidence was analyzed order to assess structural type deformation mechanism research area. Birjand mountain range, several ~E–W striking faults cut through ...

We use Interferometric Synthetic Aperture Radar (InSAR) data to derive continuous maps for three orthogonal components of the co-seismic surface displacement field due to the 1999 Mw7.1 Hector Mine earthquake in southern California. Vertical and horizontal displacements are both predominantly antisymmetric with respect to the fault plane, consistent with predictions of linear elastic models of ...

This paper presents an original use of Evolutionary Algorithms in order to approximate by a closed form the inverse kinematic model (IKM) of analytical, nonanalytical and general (i.e. with an arbitrary geometry) manipulators. The objective is to provide a fast and general solution to the inverse kinematic problem when it is extensively evaluated as in design processes of manipulators. A mathem...

The problem of fault tolerance in cooperative manipulators rigidly connected to a solid object is addressed in this paper. Four faults are considered: free-swinging joint faults, locked joint faults, incorrect measured joint position, and incorrect measured joint velocity. The faults are first detected by a fault detection and isolation system. Freeswinging and locked joint faults are isolated ...

[1] We simulate surface waves in a 3-D Earth model using a spectral element method for existing kinematic source models of the MW 8.1, 25 March 1998 Balleny Islands earthquake. The 3-D model incorporates lateral variations in the crust and mantle on the basis of models Crust2.0 and S20RTS. Our objective is to investigate the fit of the observed and simulated long-period surface waves in the hop...

[1] We use interferometric synthetic aperture radar, GPS, and seismic observations spanning 5 to 18 years to reveal a detailed kinematic picture of the spatiotemporal evolution of fault slip in a region corresponding to the 30 July 1995 Mw 8.1 subduction zone megathrust earthquake in northern Chile. In a single area, we document a complex mosaic of phenomena including large earthquakes, postsei...

Seismic reflection profiles, drill-hole data, and geologic maps delimit the form of normal faults and Tertiary sedimentary rocks in the southern half of the Cache Valley basin in northern Utah. Dips of faults and sedimentary rocks were estimated from time-migrated reflection profiles by using the stacking velocities for the data. At the southern end of the basin, the East Cache fault zone is li...

This study presents an approach, the unit circle (UC), to the qualitative representation of kinematic robots. A robot is described as a collection of constraints holding among time-varying, interval-valued parameters. The UC representation is presented, and the continuous motion of the end-effector is evaluated by the change of directions of qualitative angle and qualitative length. Analytical ...
