The spectral representation of a moving average process obtained as a convolution of a kernel with a general noise measure is studied. A proof of the spectral theorem that yields explicit expression for the spectral measure in terms of the noise measure is presented. The main interest is in noise measures generated by second order Lévy motions. For practical considerations, such measures are easil

Alluvial channel sands in active ephemeral streams are potentially highly productive aquifers that are normally fully recharged annually. The groundwater resource is constrained by the limited three-dimensional extent of these aquifers. Concepts are developed that propose an increase in alluvial aquifer dimensions at geological boundaries. Multi-electrode resistivity and ground penetrating radar a

Reprint of chapter in C. Shore and D. Haller, 'Understanding Corruption: Anthropological Perspectives' from 2005. Discusses doing good and corruption fighting as a new wave, with a focus on the international NGO Transparency International.

When the ethnographer Wilson Wallis did his first fieldwork among the Canadian Mi’kmaq Indians 1911, one recurrent character in their oral tradition was the traditional culture hero Kluskap. When Wallis returned to Nova Scotia in 1953 he found that not many Mi’kmaq in the thirties had heard about Kluskap, and if they had, it was through books or the television series “The Adventures of Glooscap”.

Numerical analysis, such as the finite element method is the most used computational procedure for nonlinear deformation and strength analysis of structures. In order to obtain meaningful results the material behaviour must be described and simulated accurately. Another important element in order to perform the simulation is a robust and accurate numerical integration algorithm. The present paper

This dissertation investigates nanomagnetism in small transition metal clusters and the diluted magnetic semiconductor (Ga,Mn)As. We derive quantum mechanical models aimed at a realistic description of the low energy physics in these systems. The main focus of the work presented is on magnetic anisotropy, the effects of spin-orbit interaction and quantum geometric phases. The first part of the the

We consider the problem of modeling and control of the nonlinear dynamics of a micro manipulator, utilized for machining operations in combination with industrial robots. Position control of the micro manipulator is a challenging problem because of the actuation principle, which is based on piezo-actuators with inherent nonlinear behavior. The major nonlinearities in the manipulator are identified
