This paper reviews the development and experimental evaluation of three techniques for estimating the alignment matrix of Doppler sonars, which are commonly used for precision navigation of oceanographic submersibles, ...

Hydrothermal systems at mid ocean ridges are a unique environment which connect the mantle, lithosphere, ocean, and biosphere in one complex system. Fluid chemistry is one key tool in understanding this environment, and ...

An essential problem of CO2 capture and storage technologies is finding sufficiently large geologic depositories to store the captured anthropogenic CO2.  Additionally, due to the subsurface temperature profile of ...

Over the past decade, high-brightness monochromatic (colored) LEDs have been replacing traditional incandescent light sources in certain niche applications such as traffic signals and “EXIT” signs. LEDs are able to save ...

Organic photovoltaics have the potential to become an accessible form of alternative energy production because of their ease of manufacture via traditional printing techniques and consequent low cost.1 However, the ...

Access to modern energy services is central to enhancing rural incomes, reducing poverty and achieving the Millennium Development Goals; however, it is not sufficient in and of itself (Barnes 1988; Barnes & Floor 1996; ...

Singular value decomposition (SVD) is often used as a tool to analyze particle image velocimetry (PIV) data. However, experimental error tends to corrupt higher SVD modes, in which the root mean square velocity value is ...

In this study, acoustic profiling techniques are used to resolve the two-dimensional spatial structures of the oscillating boundary layer in a phase-averaged sense over a wave orbital amplitude. The principal objective ...

This paper reviews the development and experimental evaluation of three techniques for estimating the alignment matrix of Doppler sonars, which are commonly used for precision navigation of oceanographic submersibles, ...

A sustainable energy future is critical for environmental and strategic reasons. Fossil fuel use has increased greenhouse gas emissions, and continued consumption could adversely change global climate. In addition, the ...
