Uniqueness of bridge surfaces for 2-bridge knots
Any 2-bridge knot in S has a bridge sphere from which any other bridge surface can be obtained by stabilization, meridional stabilization, perturbation and proper isotopy.
متن کاملThe Kauffman Polynomials of 2-bridge Knots
The 2-bridge knots (or links) are a family of knots with bridge number 2. A 2bridge knot (link) has at most 2 components. Except for the knot 85, the first 25 knots in the Rolfsen Knot Table are 2-bridge knots. A 2-bridge knot is also called a rational knot because it can be obtained as the numerator or denominator closure of a rational tangle. The rich mathematical aspects of 2-bridge knots ca...
متن کاملDevelopment of Inspection Robots for Bridge Cables
This paper presents the bridge cable inspection robot developed in Korea. Two types of the cable inspection robots were developed for cable-suspension bridges and cable-stayed bridge. The design of the robot system and performance of the NDT techniques associated with the cable inspection robot are discussed. A review on recent advances in emerging robot-based inspection technologies for bridge...
متن کاملDetecting System Design of Bridge Cables
In this paper, we designed a new detecting system of bridge cables with a snake-shaped robot. It can solve the problems such as inefficiency and danger of aloft work in the bridge detecting by workers. The detecting system of the bridge cables includes: a snake-shaped robot; a multiple and monocular vision detection module; a nondestructive magnetic leakage detecting module; a magnetostrictive ...
متن کاملHidden Symmetries of Cyclic Branched Coverings of 2-bridge Knots
We consider hyperbolic 3-manifolds Mn(K), which are nfold cyclic branched coverings of 2-bridge knots K. We show that for n ≥ 5 the orientation-preserving isometry group of Mn(K) either is a lift of a symmetry group of K or has a very special structure.
