Rollercoasters and Caterpillars

A rollercoaster is a sequence of real numbers for which every maximal contiguous subsequence, that is increasing or decreasing, has length at least three. By translating this sequence to a set of points in the plane, a rollercoaster can be defined as a polygonal path for which every maximal sub-path, with positiveor negative-slope edges, has at least three points. Given a sequence of distinct r...

Universal caterpillars

For a class V of graphs, denote by a(@?) the least value of m so that for some graph II on m vertices, every GE Q occurs as a subgraph of U. In this note we obtain rather sharp bounds on u(q) when Q is the class of caterpillars on n vertices, i.e., tree with property that the vertices of degree exceeding one induce a path. Recently several of the authors have investigated graphs U(g) which are ...

Caterpillars and moths.

Lepidoptera (moths, butterflies, and caterpillars) are an uncommon cause of adverse reactions in humans. Most reactions to Lepidoptera are mild and self-limited; however, reactions in sensitive individuals and reactions to particular species can be severe and life threatening. Specific syndromes caused by Lepidoptera include erucism (cutaneous reactions from contact with caterpillars, moths, or...

Fleas, Caterpillars and Cockroaches

There is no doubt that the coming decades will see a continued increase in the application of robotics in our daily lives. It is vital that we encourage more young people to pursue careers in STEM fields and in particular, robotics. Universities can play their part by running events that allow participants to explore the field of robotics through hands-on projects. In this paper our experiences...
