The distribution of the number of fiber intersections determines the non-uniformity of the basis weight and can be used in designing optimal control strategies relating to such physical properties as strength, elongation, air/water permeability, acoustics and filtering efficiencies of fiber webs and nonwoven fabrics. This paper developed a geometrical and probabilistic model for the number of fiber intersections in two-dimensional random fiber webs, where two distinct fiber lengths are mixed at varying ratios. This work is an extension of a previously derived paper where the model assumed that all fiber lengths are equal. Here, we present a geometrical probabilistic model, theories for deriving expectations and variances of the number of intersections in random fiber webs. The model and statistical parameters are validated through an extensive computer simulation study.}, number={15-16}, journal={TEXTILE RESEARCH JOURNAL}, author={Chun, Heuiju and Suh, Moon W.}, year={2020}, month={Aug}, pages={1851–1859} } @article{jo_suh_oh_kim_bae_choi_han_2014, title={Automatic human body segmentation based on feature extraction}, volume={26}, ISSN={["1758-5953"]}, DOI={10.1108/ijcst-10-2012-0062}, abstractNote={ Purpose – Automatic segmentation of unorganized 3D human body scan data was developed without heuristic specified values.

The process conditions are optimized with respect to the fiber and bundle properties. Otherwise, the output fiber bundle becomes non-uniform in its linear density. This research deals with finding the changes in linear density of the output bundle when perturbations are applied to the drafting conditions. Perturbations with specific autocorrelation functions were generated by the random phase spectral method. Along with the stochastically generated test signals, the transient linear density profiles of the fiber bundle in the drafting zone were simulated by using a mathematical model describing the dynamics of the roller drafting, and thus, the linear density of the output bundle could be predicted. Our results showed that the disturbances in input linear density affected the transient profiles of the linear density of the fiber bundle inside the draft zone. It was also shown that the output irregularities were strongly influenced by the perturbation in the input bundle thickness. During drafting, the perturbations in the draft ratio perturbations were not shown to have influenced the transient profiles of the bundle linear density inside the draft zone. However, the variation in the linear density appeared again in the output bundle following exactly the changes in the daft ratio. Disturbances in the process speed, however, were not shown to have influenced the output variation.}, number={10}, journal={JOURNAL OF THE TEXTILE INSTITUTE}, author={Kim, Jong S. and Suh, Moon W. and Huh, You}, year={2012}, pages={1055–1062} } @article{kim_huh_suh_2010, title={A method to generate autocorrelated stochastic signals based on the random phase spectrum}, volume={101}, ISSN={["1754-2340"]}, DOI={10.1080/14685240802528443}, abstractNote={Most of the random signals used to analyze the quality of an industry product or process disturbance have properties that can be described by an autocorrelation function.

Then, the autocorrelation functions of the generated signals were compared with the assigned autocorrelation functions. Results showed that stochastic signals with five different types of autocorrelation functions could be effectively produced by the suggested method, which we have called the “Random Phase Spectral Method”.

The outcome of analysis shows the significant but negative effect of NAFTA on the industry's profit performance in the early years of the agreement, probably due to intensified import competition, fall of real output prices, and numerous mill closings. NAFTA, however, is identified as less significant than variable input prices of labor, material, and electricity. The elasticity estimates show the dominant role of maintenance and capital expenditures, followed by textile output and variable input prices in order, in determining the industry's output supply and input demand.

Bale selection is done in such a way that the variance of single fiber breaking elongations can be minimized within a laydown of 29 bales as well as among the fibers to be found within an arbitrary cross section of the yam produced from the laydown. The study shows that the variance of the HVI breaking elongations obtained from the cotton bales is useful for maximizing the resulting yarn strengths, especially when they are combined with the Mantis® single fiber test results. In addition, a follow-up study analyzes the HVI data and matching physical test data obtained from a 2-year production period. In all, 121,200 bales (4180 laydowns) are tested for HVI bundle strength, elongation, micronaire, length, and other properties. As in the exploratory study, the cotton bales are processed into 94.4 tex open-end spun yams and an identical denim fabric. The final analysis shows that the between-bale variance of HVI bundle breaking elongations within a laydown is quite useful as a criterion for bale selection and yarn and fabric strength maximization. An enhanced method is also developed to make use of the HVI elongation data together with the Mantis single fiber tensile test results. The new procedure is even more effective at maximizing yarn and fabric strengths. }, number={6}, journal={TEXTILE RESEARCH JOURNAL}, author={Koo, HJ and Suh, MW}, year={1999}, month={Jun}, pages={447–456} } @inproceedings{suh_lee_1999, title={Modeling of U.S. men's apparel consumption trends and its implication on cotton consumption}, booktitle={Beltwide Cotton Conferences.
