Random Spacing between Metal Tree Electrodeposits in Linear DLA Arrays

Patterning metallic electrodeposits with magnet arrays

The influence of a pattern of a magnetic field on the structure of metal deposits at the cathode of a small electrochemical cell is investigated for cobalt, nickel, copper, and zinc. The different magnetic properties of the ions in their oxidized and reduced states, together with the influence on the patterned electrodeposits of variables, including the structure of the array of small magnets u...

Random Beam Patterns from Linear Arrays

The design of linear microphone arrays with randomly spaced elements is investigated. The probability distribution function for the element positions is derived in the continuum limit by matching the response of the array to an objective beam function. An analysis of the expected value and variance of the beam is presented as a function of the angular direction. Comparison of these metrics to t...

The Effects of Interelement Spacing in Linear Arrays on Throughput Performance in Ad Hoc Networks

With the high demand for improved signal link quality in ad hoc networks, devices configured with omnidirectional antennas can no longer meet the growing needs in throughput performance, and alternative approaches using antenna arrays that provide directional radiation patterns are sought. This study models an 8-element linear antenna array and examines the effects of interelement spacing of th...

On random sequence spacing distributions

The random model for allocation of an amino acid A at locations along a protein chain is controlled by an underlying binomial distribution for occurrence of A, with density given by the relative abundance of A. Here we derive analytically the distribution of lengths of inter-A spaces in sequences of arbitrary length n, with arbitrary relative abundance p of occurrencies of A. This provides a we...
