1. Kuijpers, Alexandra. EVALUATION OF PHYSICAL AND VIRTUAL FABRIC DRAPE CREATED FROM OBJECTIVE FABRIC PROPERTIES.

Degree: 2017, University of Manchester

This research aims to obtain more insight into the perception of fabric drape and how this relates to virtual fabric drape created based on objective fabric properties using commercial software applications, as well as the suitability of the currently used objective fabric measurement technologies for this purpose, and subsequently how this insight can contribute to comprehensible assessment of fabrics in a virtual or digital environment.The fashion and clothing industry can speed up work processes, increase accuracy and reduce material consumption by implementing 3D virtual technology in fit, design and sales. Although the interest in 3D technology increases, the implementation on a large scale is slow. Key for a successful implementation is an accurate, reliable and seamless interaction between virtual humans, 2D patterns and virtual fabrics.Subjective and objective data were acquired. With established instruments the measurements were taken from a range of 12 selected fabrics; the drape coefficient with the Cusick drape tester, the fabrics physical and mechanical properties with the Kawabata Evaluation System for Fabrics (KES) and Fabric Assurance by Simple Testing (FAST). The data of KES and FAST were used to simulate the virtual cloth, from which a virtual drape coefficient was derived.Drape images were created from two different viewpoints and videos from one view point, both on two different supports. The input of an expert textile panel to define the fabric drape based on these drape images was used to categorise the fabric drape and to retrieve identifying key-words. An expert user panel validated the drape categories and key-words. They also defined the stiffness and amount of drape, as well as the drape similarity of both the physical and virtual cloth. Additionally, they gave their preference for the support and view to obtain information about the fabric drape.The relationships between drape coefficient and physical and mechanical properties were statistically investigated, as well as the relationships between the physical and virtual fabric drape coefficient. These objective measurements were correlated with the subjective data. For the correlations Pearson’s correlation coefficient was used and the significance values were obtained.The agreement of the user panel with the drape categories defined and evaluated by the textile panel was high. Further, the agreement of the user panel was above 78% for the majority of the identifying key words. The information obtained from the abstracted drape profile was valuable and the sphere support and the 3D videos of the drape were most preferred.High correlations were found between the drape coefficients, of the real and virtual drape, and of the subjective assessment of stiffness and the amount of drape. Positive significant correlations were found between the drape coefficients and bending and shear properties measured with KES and FAST, as well as with the fabrics’ weights. The panels were able to classify fabrics in categories based on the way they drape and… Advisors/Committee Members: CLARKE, NICHOLAS NA, Gong, Hugh, Clarke, Nicholas.

The object of the research is the features of computer network packet traffic, the impact of network node features on computer network traffic service, methods of real-time network traffic features analysis and their application for dynamic prognostication of network traffic variances. The aim of work is to investigate fractal processes in computer networks, grounding on the results obtained to select methods suitable for real-time analysis of network traffic and to work out methods for real-time measurement of self-similarity as well as to apply it for perfection of computer networks service quality. Possibilities for mathematical modelling of network components, computer network packet traffic models and models using service theory instruments have been analysed. The package of network traffic features analysis has been worked out; it was used for analysis, assessment and comparison of methods for computer networks fractality and self-similarity research.

3. Huang, Heng. Facility layout using layout modules.

Degree: PhD, Industrial and Systems Engineering, 2003, The Ohio State University

The Functional, Flowline and Cellular Layouts are traditional facility layouts that have been discussed in the literature and implemented in industry. Selection of an appropriate layout for a multi-product facility poses a major challenge since the best decomposition of its material flow network is usually achieved by a hybrid layout that must combine the flow and machine grouping attributes of the three traditional layouts. Unfortunately, the Systematic Layout Planning (SLP) design process does not describe specific methods for product mix segmentation and department planning for design of jobshop layouts. It lacks a systematic method for varying the manufacturing focus of the different planning departments (or activities) into which the jobshop can be decomposed. We enhance the SLP process by integrating Production Flow Analysis (PFA) into SLP. Adoption of algorithms and principles of PFA in the process of SLP can eliminate the two limitations of SLP: (a) incapability of using product routings, instead of the From-To chart, as input data, and (b) incapability of generating layouts that are a hybrid combination of Functional and Cellular layouts. A review of the literature shows that a fundamental requirement for the design of modern facility layouts is the distribution of identical machines at multiple locations in the facility. Our research shows that the material flow network in any facility layout can be decomposed into a network of layout modules, with each module representing a portion of the entire facility. A layout module is defined as a group of machines connected by a material flow network that exhibits a flow pattern characteristic of a specific type of layout, such as the Flowline, Cellular or Functional Layout. The concept of layout modules extends current thinking on input data requirements and methods for facility layout, and supports the need for a new generation of facility layouts beyond the three traditional layouts that continue to be studied and implemented in industry. We propose a group technology based heuristic approach as an alternative method for generation of layout modules and design of modular layouts, based on a new similarity measure for comparison of operation sequences.
