This paper studies and estimates soil resistivity parameters of two-layer vertical soil as a one of the practical soil models. Wenner method is used to measure the apparent soil resistivity. To achieve this study, the image method is proposed to consider the presence of vertical layer soil and four electrodes of the Wenner method. A general apparent resistivity expression is proposed to find the relation...
Jointed 12-phase-transmission lines are frequently used in power systems. However, it is subjected to a variety of technical problems on fault analysis and protection engineering. These problems are mainly due to the mutual coupling effects between adjacent circuits of the line. A method to decouple the mutual impedance completely was proposed in this paper. When fault occurs in the 12-phase-transmission...
A triangular decomposition method with controlling parameter for cyclic block tridiagonal systems is presented. Numerical example show that the method can reduce the computation time over 40% more than the directly triangular decomposition method.
Due to its significant potential applications, underwater chemical plume exploration and source localization via an autonomous underwater vehicle (AUV) is currently a hot subject both in AUV and oceanic engineering research communities. Chemical plume including buoyant stem and non-buoyant part such as deep-sea hydrothermal plume is a typical dynamic 3D feature in the ocean environment; therefore,...
In order to model a wheeled mobile robot (WMR) system to improve its maneuverability in a real environment, wheel dynamics, which may violate no-slipping and pure rolling constraints, needs to be studied. In this paper, wheel dynamics with slip is modeled and introduced into the robot overall dynamics. Wheel slip phenomenon is captured and at the same time accommodated. Considering both lateral and...
