The response uniformity of a 90]290 cm2 RPC prototype working in avalanche mode has been tested using cosmic rays. The high statistics needed for the test has also been used for accurate e$ciency studies. The intrinsic detector ine$ciency free, from spacers e!ects has been measured. ( 2000 Elsevier Science B.V.

The equilibrium properties of isolated ring molecules were investigated using an off-lattice model with no excluded volume but with dynamics that preserve the topological class. Using an efficient set of long range moves, chains of more than 2000 monomers were studied. Despite the lack of any excluded volume interaction, the radius of gyration scaled like that of a self avoiding walk, as had be...

As we know, histogram matching is a commonly-adopted technique in the applications of pattern recognition. The matching of two patterns can be accomplished by matching their corresponding histograms. In general, the number of features and the resolution of each feature will determine the size of histogram. The more the number of features and the higher the resolution of each feature, the strong...

<p style='text-indent:20px;'>The small and large size behavior of stationary solutions to the fragmentation equation with diffusion is investigated. It shown that these behave like stretched exponentials for sizes, exponent in exponential being solely given by overall rate at infinity. In contrast, partially governed daughter distribution most linear, possibly non-algebraic behavior. Expl...

lipoma is a benign mesenchymal tumor of fat with uncertain pathogenesis. although the most common mesenchymal neoplasm in trunk and proximal portions of the extremities, it is rarely seen in the oral cavity. oral lipomas are clinically soft, smooth-surfaced nodular masses that mostly are less than 3 cm in size. typically the tumor is asymptomatic unless bitten or become noticeable because of th...
