Performance based assessment of offshore wind turbine platform using the constrained new wave method
The purpose of this study is to provide a more accurate and practical method than static and spectral methods to assess the offshore wind turbines that are loaded with both wave and wind time history, the structure is evaluated by increasing the load intensity in successive steps to the stage of failure and the performance of the platform in different wave patterns are investigated. In this stu...
This paper describes a framework and algorithms for robust kinematic design of mechanical assemblies. The framework, developed over a period of ten years, is based on the configuration space method and supports automatic modeling, nominal and toleranced analysis, and part tolerance envelope computation of open and closed loop planar mechanisms with multiple, changing contacts. It also supports ...
This paper presents the velocity kinematic modeling of wheeled mobile robots (WMRs) by applying the matrix coordinate transformation to every pairs of WMRs including wheeled pairs which were dealt with ad-hoc manners in the previous methodologies. A wheeled pair is not replaced with a planar pair and its kinematics is formulated together with those of lower pairs, even though there exists 2 DOF...
avo analysis in ghar sand stone reservoir in aboozar oil field located in north-west of persian gulf
avo theory was introduced around 20 years ago. in recent years, this technique was become to a major tool in hydrocarbon sources exploration. by the help of this method with the suitable understanding from underground layers and knowing how to use this technology, quantitative specifications of reservoir can be recognized. avo analysis is a seismic technique that by using of pre-stack data, est...
This paper describes a method to solve the direct kinematics of a generic Stewart-Gough manipulators. The method is formulated in terms of a search in the space of rigid body transformations. The underlying idea is that the solutions of the direct kinematics can be obtained by moving the end-effector body according rotations and translations and accounting for the rigidity conditions. The paper...
The dynamic model of the octopus arm described in the first paper of this 2-part series was used here to investigate the neural strategies used for controlling the reaching movements of the octopus arm. These are stereotypical extension movements used to reach toward an object. In the dynamic model, sending a simple propagating neural activation signal to contract all muscles along the arm prod...
In isotropic bistable media, a vortex pair typically evolves into rotating spiral waves. In an anisotropic system, instead of spiral waves, the vortices can form wave fragments that propagate with a constant speed in a given direction determined by the system's anisotropy. The fragments may propagate invariably, shrink, or expand. We develop a kinematic approach for the study of vortex-pair dyn...
