Run Length Texture Analysis of Thoracolumbar Facia Sonographic Images: A Comparison of Subjects with And Without Low Back Pain (LBP)
… second-order texture analysis, and grey-level run length texture analysis are types of analysis that could be applied to quantify parameters that describe the features of the texture; the grey-level analysis is usually conducted in four directions of the texture. This study has four objectives; …

Analysis and Design of One- and Two-Sided Cusum Charts with Known and Estimated Parameters
… methods provide us with ways to approximate the run length distribution of the chart. Since parameters of the run length distribution are commonly used measures of the performance of a control chart, it is important to choose an accurate approximation method. We develop some new Markov chain …

Cooperative behavior of motor proteins
… the transport parameters walking distance or run length, velocity and force generation are measured. The results indicate that the transport parameters are influenced by the number of motors carrying the bead. While the transport velocity slightly decreases, an increase in the run length was …

Practical algorithms for image compression and surface estimation
… algorithms are innovative extensions of the Run Length Encoding image compression algorithm and the third is an image compression technique based on kriging. In general the modified Run Length Encoding algorithms yield a better compression ratio by a factor of two while retaining fast …

Exponentially Weighted Moving Average Charts for Monitoring the Process Generalized Variance
… analysis of the chart's initial and steady-state run length distributions. The three methods that are commonly used to determinate run length distribution, simulation, the integral equation method, and the Markov chain approximation are discussed. The integral equation and Markov chain approaches …

An optimization of on-line monitoring of simple linear and polynomial quality functions
… the average time to signal (ATS) and the average run length (ARL) are regarded as the objective functions, and ATS and ARL approximations, based on Markov Chain Principals, are extended and modified to capture the special structure of the profile monitoring. Furthermore,the performances of the …

Different modes of cooperative transport by molecular motors
… filaments, from which they unbind after a finite run length. Understanding how these motors interact and how their movements are coordinated and regulated is a central and challenging problem in studies of intracellular transport. In this thesis, we describe a general theoretical framework for the …

Nonparametric procedures for process control when the control value is not specified
… process control procedure can be done. The truncation point is applied to denote the finite run length or the time at which sufficient information about the distribution of the observations and/or the control value is obtained so that the procedure may be switched to a parametric procedure or …

Dynamic Probability Control Limits for Risk-Adjusted Bernoulli Cumulative Sum Charts
… chart leads to quite variable in-control average run length (ARL) performance for patient populations with different risk score distributions. To overcome this problem, the simulation-based dynamic probability control limits (DPCLs) patient-by-patient for the risk-adjusted Bernoulli CUSUM charts …

Design optimization for the two-stage bivariate pattern recognition scheme
… identification of process condition either it is running within in statistically in-control or out-of-control, whereas diagnosis refers to the identification of the source of out-of-control process. Selection of SPC scheme becomes more challenging when involving two correlated variables, which are …

Control chart procedures based on cumulative gauging scores
… sign score vector is also proposed. The exact run length distribution of these cumulative gauging score charts can be obtained by formulating the procedures as Markov chain processes. For some procedures, the average run length (ARL) can be obtained in a closed form expression by solving a …

Applications of Control Charts in Medicine and Epidemiology
… events. We compare the steady-state average run length performance of the Sets methods and its modifications to the Bernoulli CUSUM chart under a wide variety of circumstances. Except in a very few instances we find that the Bernoulli CUSUM chart performs better than the Sets method and its …

Quality and compressibility analysis of checkerboard-based digital halftoning algorithms
… the C/C++ implementation of two new and original run length encoding (RLE) methods (Villarreal, 2001). These RLE methods are used to remove the positional redundancy from the pixels composing the bi-level images. Other methods are subsequently used to remove statistical redundancies form the …
