The presented strategy of automatic baseline detection in chromatograms combines fuzzy logic and neural network approaches. It is based on a verbal description of a baseline referring to a 2D image of a chromatogram instead of a data vector. Baselines are expected to touch data points on the lower border of the chromatogram forming a mainly horizontal and straight line. That description has bee...

In this paper, we investigate one of the possibilities to adapt an unbiased moving average (MA) filter cfinite impulse response [FIRIjZter) to the slope of time error function. The linear regression coefficient is used as a statistical estimator of sample slope. We evaluate the error of the slope estimate and present two options for the adapting coefficient determination. To examine them, we ge...

water crisis resource management originates from limited resources has made it essential to study the prioritization of traditional and modern methods of sustainable water resource management. the objective of such studies is to provide a list of prioritized traditional and modern methods of sustainable water resource management. this research aims to study rainwater harvesting method and qanat...

this study aimed to determine the prone areas for sugar beet planting with regards to their major effective factors. climatic data of 1998-2009 period were obtained from the local stations of khorasan razavi meteorological bureau. the topographic data including altitude, slope, slope direction, and tin layers were extracted from 1:250000 topographic maps of cartographic organization, iran. the ...

1. Self-Organized Criticality 1.1. Introduction There is an abundance of the scale invariant phenomena in nature, e.g. fractals, earthquakes, 1=f noise, uctuation of the stock index, etc. Scale invariance means that there are many scales (or equivalently, no typical scale) in the system. One asks why and how so many diierent scales emerge naturally in a physical system. In 1987, Bak, Tang, and ...

In this paper, we determine geometric information on slope lengths of a large class of knots in the 3–sphere, based only on dia-grammatical properties of the knots. In particular, we show such knots have meridian length strictly less than 4, and we find infinitely many families with meridian length approaching 4 from below. Finally, we present an example to show that, in contrast to the case of...
