construction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
15 صفحه اولTemperature Effect and Its Elimination in Geiger - Muller Tube Counters
It has been found that in the usual form of the Geiger-Miiller tube counter the rate of counting is affected by changes of temperature. The rate of counting, at a fixed potential applied to the tube, decreases as the temperature is increased. This indicates an increase in the density of the gas in the counter. Since it is hermetically sealed this can only be caused by evaporation of volatile ma...
متن کاملMethod to Measure Indoor Radon Concentration in an Open Volume with Geiger-Mueller Counters: Analysis from First Principles
A simple method employing a pair of pancake-style Geiger-Mueller (GM) counters for quantitative measurement of radon activity concentration (activity per unit volume) is described and demonstrated. The use of two GM counters, together with the basic theory derived in this paper, permit the detection of alpha particles from decay of 222 Rn and progeny ( 218 Po , 214 Po ) and the conversion of th...
متن کاملImmunocytochemical characteristics of Müller cells cultured from adult rabbit retina.
The antigenic expression of glial fibrillary acidic protein (GFAP), vimentin, S-100 protein and neurofilament triplex polypeptide was examined in cultured glial (Müller) cells from adult rabbit retina using immunocytochemical techniques. Most of the cultured cells were labelled with carbonic anhydrase C which has been considered to be the most specific marker of Müller cells. Most of the cultur...
متن کاملImage Measurements Davi Geiger
It makes no sense to extract features at pixel level as the image is noisy and the discretization/quantization introduces artifacts. The minimum resolution in which we can look an image is an order of magnitude higher than a pixel, i.e., it is a few pixels, say 10 pixels. In an image there are various intensity discontinuities, and these are important information to preserve. Thus, when we are ...
