We present efficient algorithms to generate all edge-magic and vertex-magic total labelings on cycles, and all vertex-magic total labelings on wheels. Using these algorithms, we extend the enumeration of the total labelings on these classes of graphs.

Cycimns were originally defined as proteins which are synthesized in each cell cycle and destroyed at every mitosis. Cyclins were discovered by T. Hunt and students at the Marine Biological Laboratory, Woods Hole, MA, duningthe 1982 Physiology Course (1). They labeled eggs ofthe sea urchin Arbacia punctulata with [35S]methionine after fertilization and analyzed the temporal pattern of protein s...

The bounding gait for the Platform for Ambulating Wheels (PAW), a new and unique hybrid wheeled-leg system is presented here. Two hypotheses are tested and discussed: first, that the robot’s forward speed can be increased by increasing the leg liftoff angles and, second, that addition of distally-mounted actuated wheels can be used in running gaits such as the bound. Both hypotheses were tested...

A letter to the editor. Meals on Wheels (MOW) is a community-based not-forprofit organisation that delivers nutritious meals to vulnerable clients in the community, to enable them to maintain their health and independence within their own home. MOW meals aim to provide at least one-third of the recommended dietary intake (RDI) for energy, fibre and calcium, and one-half of the RDI for protein, ...
