This paper investigates the relationship between housing prices and the quality of public schools in the Australian Capital Territory. To disentangle the effects of schools and other neighbourhood characteristics on the value of residential properties, we compare sale prices of homes on either side of high school attendance boundaries. We find that a 5… (More)
Quantitative bounds on rates of approximation by linear combinations of Heaviside plane waves are obtained for sufficiently differentiable functions f which vanish rapidly enough at infinity: for d odd and f ∈ C d (R d), with lower-order partials vanishing at infinity and dth-order partials vanishing as x −(d+1+ε) , ε > 0, on any domain ⊂ R d with unit… (More)

A formation process for semiconductor quantum dots based on a surface instability induced by ion sputtering under normal incidence is presented. Crystalline dots 35 nanometers in diameter and arranged in a regular hexagonal lattice were produced on gallium antimonide surfaces. The formation mechanism relies on a natural self-organization mechanism that… (More)
In Lp-spaces with p an integer from [1, infinity) there exists a best approximation mapping to the set of functions computable by Heaviside perceptron networks with n hidden units; however for p an integer from (1, infinity) such best approximation is not unique and cannot be continuous.
It is shown that for any positive integer n and any function in Lp([0, 1] d) with p ∈ [1, ∞) there exists a best approximation by linear combinations of n characteristic functions of half-spaces. Further, sequences of such linear combinations converging in distance to the best approximation distance have subsequences converging to the best approximation,… (More)
This paper investigates electromagnetic interference mechanisms in flat metallic casings using the contour integral method (CIM). Coaxial monopole probes are used to represent potential radiators, and a local field model is developed and combined with the CIM for evaluation of mutual admittance between the probes. Limitations of the method are discussed.
