For a weak point source or dipole, or a small body operating as either, we show that the power from a wave energy converter (WEC) is the product of the particle velocity in the waves, and the wave force (suitably defined). There is a thus a strong analogy with a wind or tidal turbine, where the power is the product of the fluid velocity through the turbine, and the force on it. As a first appro...

iii Acknowledgments I would like to extend my sincere gratitude to my thesis director, Elizabeth Steeby, and the two committee members, Earle Bryant and John Hazlett, for their willingness to share their knowledge and viewpoints; their patience; and their wit. I would also like to thank Peter Schock, who has been invaluable to my education and intellectual development at UNO. Finally, I am ever...

Agglomeration Economies, or production cost savings due to geographic clustering of firms and industries, can enhance the growth and development of firms, industries, regions and cities. We provide an overview of the theory and empirical literature of agglomeration, and highlight several applications from the cost function perspective. These applications include cost savings from density in the...

Many wave energy conversion applications require future knowledge or forecasting of the excitation force values. Most converter (WEC) control strategies need to forecast time-series for harvesting maximization. The main aim this study is experiences by a two-body heaving point absorber WEC (as case study) using three neural network methods. calculated based on hydrodynamic characteristics consi...

A matrix inversion algorithm based on the Sherman-Morrison formula is analyzed and compared with the classical Gauss-Jordan algorithm. In particular the results obtained in a Cray T3-E by the parallel versions of both algorithms are compared. Key-Words:Sherman-Morrison formula, matrix inversion, Parallel algorithms, Cray T3-E

In quantum mechanics, the wave function embodies all the information that can be pragmatically extracted from a system. However, for a many-electron system, it is not the wave function, but it is rather the electron density that is observable by direct experimentation (for example, coherent and elastic XRay scattering). The coordinate electron density’s momentum-space analogue, viz. the electro...
