Let M be a 3-connected matroid that is not a wheel or a whirl. In this paper, we prove that M has an element e such that M\e or M/e is 3-connected and has no 3-separation that is not equivalent to one induced by M .

This paper deals with the structure of the kinematic models of wheeled mobile robots (WMR). A wheeled mobile robot here considered as a planer rigid body that rides on an arbitrary number of wheels. In this paper it is shown that, for a large class of possible configurations of wheels, five types of configurations can be done namely i) fixed standard wheels, ii) steerable standard wheels, iii) ...

anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. the distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...

On the face of it, the 5 June ruling by the U.S. Court of Appeals for the District of Columbia Circuit, affirming the earlier dismissal of the youths’ case, is a setback. However, the Court’s ruling positions the case to proceed to the Supreme Court on the question of whether the federal government has a public trust obligation to its citizens. The Court of Appeals focused on a recent U.S. Supr...

In this research we outline control system for wheels mobile rovers which are very important for recent and future research. The wheel type mobile rovers are one of the most practical and widespread robots. Wheels mobile rovers have a simple drive mechanism, and high energy efficiency. In this paper we present {2n+2, 0≤n≤3} wheels mobile rovers, presented by two wheels rover Super Mario, four w...

We build unbounded classes of plane and projective plane multiwheels that are 4-critical that are received summing odd wheels as edge sums modulo two. These classes can be considered as ascending from single common graph that can be received as edge sum modulo two of the octahedron graph O and the minimal wheel W3.

We study the unwheeled rational Kontsevich integral of torus knots. We give a precise formula for these invariants up to loop degree 3 and show that they appear as colorings of simple diagrams. We show that they behave under cyclic branched coverings in a very simple way. Our proof is combinatorial: it uses the results of Wheels and Wheelings and new decorations of diagrams.

Automated vehicles are increasingly being researched and developed to reduce accident rates. The braking system is an integral part of the safety factor in vehicle. One development systems on Anti-lock Braking System (ABS). ABS a vehicle b that prevents wheels from locking during sudden braking. research was conducted by modelling designing using SIMULINK software MATLAB. This varying coefficie...
