Let and be two sets of -monotone and non-intersecting curve segments, and . We give a new sweep-line algorithm that reports the intersecting pairs of segments of . Our algorithm uses only three simple predicates that allow to decide if two segments intersect, if a point is left or right to another point, and if a point is above, below or on a segment. These three predicates seem to be the simpl...

The subject of parameter estimation in linear FM signals embedded in White Gaussian Noise has been extensively studied. This paper will present an accurate means of estimating the unknown initial frequency f0 and frequency sweep rate m for a sinusoidal signal. Experimental results from an arbitrary signal will also be presented.

In their brochure The Principles and Applications of Cathode-Ray Polarography Southern Analytical Ltd. (Camberley, Surrey, U.K.) refer to a paper in which one of their cathode-ray polarographs is used for the determination of amino acids containing thiol and disulphide groups (Coult, 1958). This work apparently takes no account of the fact that the shape of a rapid-sweep polarogram is more depe...

Curve sawing is a primary log breakdown process that incorporates gang-saw technology to allow two-sided cants from logs with sweep to be cut parallel to the log surface or log axis. Since curve-sawn logs with sweep are cut along the grain, the potential for producing high quality straight-grain lumber and cants increases, and strength, stiffness, and dimensional stability are maximized. Presen...

The simultaneous effects of inulin addition (0-4%w/w), probiotic inoculum level (1-3%v/v) and fermentation temperature (37-45°C) on the dynamic rheological properties of probiotic non-fat yogurt were studied using response surface methodology. Frequency sweep tests were performed to measure structure strength and type of structure. Linear viscoelastic range in term of strain (LVE), structure st...

Topological sweep can contribute to efficient implementations of various algorithms for data analysis. Real data, however, has degeneracies. The modification of the topological sweep algorithm presented here handles degenerate cases such as parallel or multiply concurrent lines without requiring numerical perturbations to achieve general position. Our method maintains the O(n) and O(n) time and...

On the OMEGA laser system at the University of Rochester's Laboratory for Laser Energetics (LLE), six P5 10 streak cameras measure the pulse shape of the 60 OMEGA beam lines. These cameras use a photocathode to convert an optical signal into an electron beam. A voltage ramp then sweeps this electron beam across a phosphor screen which is in turn imaged by a CCD. Currently, 120 images of an eigh...
