Fluid inclusion microthermometric data are often reported as homogenization temperature frequency histograms. Interpretation of such histograms for a single ̄uid inclusion assemblage (FIA) of nonreequilibrated ̄uid inclusions is usually straightforward and provides an accurate determination of the original density (Th) of that FIA. However, interpretation of such histograms for reequilibrated i...

BACKGROUND AND PURPOSE Subependymal enhancement and DWI have been reported to be useful MR imaging markers for identifying true progression. Our aim was to determine whether the subependymal enhancement pattern and ADC can differentiate true progression from pseudoprogression in patients with glioblastoma multiforme treated with concurrent chemoradiotherapy by using temozolomide. MATERIALS AN...

In this paper a novel technique, Authentication and Secret Message Transmission using Discrete Fourier Transformation (ASMTDFT) has been proposed to authenticate an image and also some secret message or image can be transmitted over the network. Instead of direct embedding a message or image within the source image, choosing a window of size 2 x 2 of the source image in sliding window manner an...

A new one-pot preparative route was developed to synthesize novel organophosphorus-sulfur heterocycles via the reaction of the four-membered ring thionation reagent [2,4-diferrocenyl-1,3,2,4-diathiadiphosphetane 2,4-disulfide (FcLR, a ferrocene analogue of Lawesson's reagent)] and alkenyl/aryl-diols and I₂ (or SOCl₂) in the presence of triethylamine. Therefore, a series of five- to ten-membered...

We propose a novel visual navigation clue based on summarising the local 3D information into a single structure, called pqhistogram. This structure is obtained by discretising the local orientation or [p, q] of an image, and building a two dimensional histogram. This histogram gives a global view of the 3D shape of the world, therefore it could be used for navigation. The potential application ...

A simple algorithm for estimating the regression function over the United States is introduced. The approach allows for data obtained from a complicated sampling design, as well as for the inclusion of a few additional covariates. The regression estimates are obtained from an associated probability density estimate, namely the averaged shifted histogram. The algorithm has proven especially succ...

The bimodality of a population P can be measured by dividing its range into two intervals so as to maximize the Fisher distance between the resulting two subpopulations P1 and P2. If P is a mixture of two (approximately) Gaussian subpopulations, then P1 and P2 are good approximations to the original Gaussians, if their Fisher distance if great enough. For a histogram having n bins this method o...

The purpose of this paper is to propose a new histogram-based diflerential current testing procedure of active defects. This procedure contains three steps: Preanalysis, Failure Analysis, and Production Testing. The main objehtives of the Pre-analysis are to provide information on the most frequent active current defects and to help ‘setting the limits between faulty and fault-free devices: the...

This vignette is designed to give a short overview about Pareto Distributions and Generalized Pareto Distributions (GPD). We will work with the SPC.we data of our quantmod vignette. Therefore we have to reproduce the SPC.we data in exactly the same way as described the quantmod vignette. In financial data analysis stock indices as the S&P 500 index are typically analyzed by using the returns of...
