In the multipolar abdominal stretch receptors of the crayfish and lobster, action potentials are initiated in a segment of the axon central to the cell body (Case, Edwards, Gesteland & Ottoson, 1957; Edwards & Ottoson, 1958; Eyzaguirre & Kuffler, 1955). Since the soma lies at the periphery, close to the receptor region in the dendrites, the initial excitation set up by the mechanical stimulus m...

The Infostations wireless data network architecture features discontinuous coverage and ultra-high radio rates for burst transfers of information between base and mobile. It has been shown previously that the infostations architecture can greatly increase the capacity of wireless data systems at the expense of increased delivery delay. In this work we explicitly consider the multiple access iss...

A mine planning that takes place regardless of the uncertainty in price just develops an optimized plan at the starting time of the mining operation. Given the price change over the life of mine, which is quite certain, optimality o...
