The current literature on optimal forest rotation makes the unrealistic assumption of constant interest rate though harvesting decisions of forest stands are typically subject to relatively long time horizons. We apply the single rotation framework to extend the existing studies to cover the unexplored case of variable interest rate. We show that even in the deterministic case if the current in...

Decomposition of perfluorooctanoic acid (C7F15COOH, PFOA) has been gaining increasing interests because it is a ubiquitous environmental contaminant and resistant to the most conventional treatment processes. In this work, the rapid and complete mineralization of PFOA and simultaneous defluorination were achieved by γ-ray irradiation with a (60)Co source. The degradation rate of PFOA by γ-ray i...

Evidence has been mounting (over the centuries) that the interest based debt financing regime is under ever increasing distress. All of the earlier crises whatever label they carried− exchange rate crisis or banking crisis – have been debt crises in essence. At the present, empirical research suggests that the debt-to-GDP ratio of the richest members of the G-20 threatens to touch 120% m...

We present a system for coding synthetic aperture radar (SAR) imagery, whereby regions of interest and background information are coded independently of each other. A multiresolution constant-false-alarm-rate (CFAR) detection scheme is utilized to discriminate between target regions and natural clutter. Based upon the detected target regions, we apply less compression to targets, and more compr...
