In the master-slave heterogeneous teleoperation, workspace of slave manipulator is usually much larger than that master manipulator. This paper proposes a 6-DOF bilateral hybrid teleoperation control strategy to map manipulators without changing operation accuracy. The includes admittance and force based on feedback sensor at end two strategies switched autonomously through positioning Sigma.7 ...

We examine the line-wrap feature of text processors. We show that adding characters to previously formatted lines leads to the cascading of words to subsequent lines. The length of these cascades shows a power-law distribution. We show that this system is in a state of self-organized criticality. The connection to onedimensional random walks and diffusion problems is demonstrated. Of particular...

In this paper, we introduce a new skewed distribution of which normal and power normal distributions are two special cases. This distribution is obtained by taking geometric maximum of independent identically distributed power normal random variables. We call this distribution as the power normal--geometric distribution. Some mathematical properties of the new distribution are presented. Maximu...

in methods presented to calculate the voltage collapse point, the transmission system is usually the only part of the power system that is completely modeled. distribution systems are often replaced by aggregate load models because the use of the detailed model of distribution systems in voltage stability analysis not only increases the computation time, but also decreases the probability of co...

Cascading failures in large-scale electric power transmission systems are an important cause of blackouts. Analysis of North American blackout data has revealed power law (algebraic) tails in the blackout size probability distribution which suggests a dynamical origin. With this observation as motivation, we examine cascading failure in a simplified transmission system model as load power deman...
