Six candidate height-diameter models were used to analyze the height-diameter relationships. The common methods for estimating the height-diameter models have taken the classical (frequentist) approach based on the frequency interpretation of probability, for example, the nonlinear least squares method (NLS) and the maximum likelihood method (ML). The(More)
Introduction Solar irradiation is the most abundant energy source available but it is distributed and intermittent, thereby necessitating its storage via conversion to a fuel (e.g., hydrogen). One possible route for direct solar-hydrogen production is through an integrated electrochemical device that uses light-capturing semiconductors in contact with(More)
