This paper describes the results of using genetic programming to evolve models that predict the throughput in disk arrays. The results are compared to previous hand-crafted analytical and automatically-generated interpolation-based device models. An analysis is performed to investigate the optimality of the run parameters chosen as well as to discover whether the approach has the tendency to ov...

In these notes we describe how to measure the confidence we have in our Monte-Carlo estimates. In particular, we use he Central Limit Theorem to construct confidence intervals for the quantity we are truing to estimate. We also describe methods to estimate the number of samples that are required to achieve a given confidence level.

With the dramatic increase of 3D imaging techniques, there is a great demand for new approaches in texture analysis of volumetric data. In this paper, we present a new approach for volumetric texture analysis using a runlength encoding matrix and its texture descriptors. We experiment with our approach on the volumetric data generated from two normal Computed Tomography (CT) studies of the ches...

Abstract – Various problems in physics and engineering lead to the problem of runlength probability distribution function (pdf) in a finite time series. In this study to find the pdf of run-lengths in such a series, first infinite sequence properties are reviewed and then finite series run length pdf is derived on the basis of simple set theory. This paper presents the derivation of exact run l...

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...
