introduction: the aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.methods: thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. after access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. wi...
Mukherjee and Chakraborti 1 proposed a single distribution-free (nonparametric) Shewhart-type chart based on the Lepage 2 statistic for simultaneously monitoring both the location and the scale parameters of a continuous distribution when both of these parameters are unknown. In the present work, we consider a single distribution-free CUSUM chart, based on the Lepage 2 statistic, referred to as...
Increased competition on the global market forces producers to follow policies leading to finite production runs. This situation requires implementation of a new type of inspection procedures with the aim to improve or sustain production quality levels. One of the most important aspects in the design of inspection processes is the specification of inspection intervals. This paper provides a sim...
A fast, reliable, and objective system for computerized classification of color textured perthite images is proposed. Computerized classification of perthite textures enables large scale comparative perthite texture studies. In order to locate a perthite crystal’s borders, color and texture features are combined in a pixel classification segmentation operation, followed by probabilistic relaxat...
The performance of attributes control charts (such as c and np charts) is usually evaluated under the assumption of known process parameters (i.e., the nominal proportion of nonconforming units or the nominal number of nonconformities). However, in practice, these process parameters are rarely known and have to be estimated from an in-control phase I data set. In this paper, we derive the run l...

A method for encoding and decoding spectrum shaped binary run-length constrained sequences is described. The binary sequences with predefined range of exponential sums are introduced. On the base of Cover’s enumerative scheme, recurrence relations for calculating the number of these sequences are derived. Implementation of encoding and decoding procedures is also shown.
The run vector of a binary sequence reflects the run structure of the sequence, which is given by the set of all substrings of the run length encoding. The run vector and the aperiodic autocorrelations of a binary sequence are strongly related. In this paper, we analyze the run vector of skew-symmetric binary sequences. Using the derived results we present a new and different proof that there e...
