in this paper, an innovative mobile platform is presented which is equipped by three new wheels. the core of the new idea is to establish a new design of rigid circular structure which can be implemented as a wheel by variable radius. the structure of wheel includes a circular pattern of a simple two-link mechanism assembled to obtain a wheel shape. each wheel has two degrees of freedom. the fi...

Layer-bound, low-displacement normal faults, arranged into a broadly polygonal pattern, are common in many sedimentary basins. Despite having constrained their gross geometry, we have a relatively poor understanding of the processes controlling the nucleation and growth (i.e., the kinematics) of polygonal fault systems. In this study we use high-resolution 3-D seismic reflection and borehole da...

Analog modeling of a flat-ramp-flat fault system was performed and its geometry displacement field were compared to those different kinematic models such as classical bend folding, parallel flow, incline-shear, curvilinear hinge, backlimb trishear. To obtain the vectors analog experiment, Particle Image Velocimetry performed. All analyzed could explain general configuration folding. However, on...

On 3 April 2017, a Mw 6.5 earthquake occurred in Botswana, representing the secondstrongest earthquake registered since 1949. Such an intraplate event occurred in a low seismic hazard area and was suspected to be an artificial earthquake induced by nearby anthropogenic activities (gas extraction). The possible relation between anthropogenic activities and the earthquake occurrence has been qual...

In recent years, there is an increasing interest in developing geometric algorithms for kinematic computations. The aim of this paper is to present the notion of projective convexity as a key element for a new framework for kinematic geometry, that allows for the development of more elegant and efficient algorithms for geometric computations with kinematic applications. The resulting framework,...

The western part of N 2 area is located at the tectonic high point D oil field, with faults cut into each other, staggered distribution and complex fracture structure. In this paper, based on 3D seismic interpretation, research fault geometry, kinematic characteristics, deformation period grade division are systematically carried out. quantitative discriminatory criteria plane segmental growth ...

Objects with various types of mechanical joints are among the most commonly built. Joints implement a vocabulary of simple constrained motions (kinematic pairs) that can be used to build more complex behaviors. Defining physically correct joint geometry is crucial both for realistic appearance of models during motion, as these are typically the only parts of geometry that stay in contact, and f...

We use three-dimensional dynamic (spontaneous) rupture models to investigate the nearly simultaneous ruptures of the Susitna Glacier thrust fault and the Denali strike-slip fault. With the 1957 Mw 8.3 Gobi-Altay, Mongolia, earthquake as the only other well-documented case of significant, nearly simultaneous rupture of both thrust and strike-slip faults, this feature of the 2002 Denali fault ear...
