A major limitation for future nanotechnology, particularly for bottom-up manufacturing is the non-availability of 2-dimensional massively parallel probe arrays. Scanning proximity probes are uniquely powerful tools for analysis, manipulation and bottom-up synthesis: they are capable of addressing and engineering surfaces at the atomic level and are the key(More)
where n is the sample size, h is the bandwidth of the spectral cutoff estimatorˆf n , β ≥ 0 is such Φ ψ (t)t β → C, t → ∞ for the characteristic function Φ ψ of ψ and some constant C ∈ C, and g = f * ψ. We derive the asymptotic distribution of Y n (t) and use it to construct asymptotic confidence bands for f (Bissantz, et al., 2005). Moreover, we establish(More)

An inversion formulation for crustal structure using seismic attributes has been developed. The seismic attributes include envelope amplitude, instantaneous frequency and phase time of selected seismic phases. Complex trace analysis is used to extract different seismic attributes from the seismic data. For the inversion of seismic attributes, ray(More)
