Canopy height distributions were created from small-footprint airborne laser scanner data for mature coniferous forest in two forest areas in Norway. In total, 82 and 70 georeferenced field sample plots and 39 and 38 forest stands were measured in the two areas, respectively. The average sampling densities were 1.2 m and 0.9 m. Height percentiles, mean and maximum height values, coefficients of...

Using prototype modules of the ALICE Transition Radiation Detector we investigate space charge effects and the dependence of the pion rejection performance on the incident angle of the ionizing particle. The average pulse height distributions in the drift chambers operated with the Xe,CO2(15%) mixture provide quantitative information on the gas gain reduction due to space charge accumulating du...

2. Transient Probability Distributions of Nerve Impulse Intervals, S. B. Thesis, Department of Physics, M.I. T., June 1964. The time evolution of the distribution of nerve-impulse intervals was examined by measuring histograms at varying times in the stimulus cycle. The distribution width was found to vary inversely as the stimulus strength. There is an indication that the width also depends up...

lead forms the complexes with xylenol orange in the basic solution. an adsorptivedifferential pulse stripping method for the determination of lead is proposed. the procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (hmde) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. the opt...
