Virtual clothing in hybrid cellular automata

An interactive clothing system is one of the basic components of virtual reality. The clothing is implemented via design of two‐dimensional garment panels and putting the panels on an actor in a realistic way. We show how to ease this time consuming task by appealing to a hybrid cellular automaton as a parallel computing device. We draw our approach on a fact that the draping fabric bears a feature of natural parallelism. At a very short time scale behavior of any node point of a fabric depends only on the behavior of its closest neighboring node points. Therefore distant regions of the fabric can be simulated independently. Basing on the problem's natural parallelism we design two‐dimensional network of uniform locally connected hybrid automata that execute in parallel a particle model of draping behavior of clothes on a standing mannequin.

Adolescents' Clothing Purchase Motivations, Information Sources, and Store Selection Criteria: A Comparison of Male/Female and Impulse/Nonimpulse Shoppers

The purpose of this study was to examine high school adolescents' clothing shopping frequency, expenditure, purchase motivations, information sources, and store selection criteria and to determine the similarities and differences between male and female as well as impulse and nonimpulse shoppers. A survey design was used to collect the data. One hundred thirty‐seven high school students, in 9th to 12th grade, 69 males and 68 females, were recruited. Similarities were found between male and female participants. They spent similar amounts of money on clothing and had similar degrees of conformity, sexual attraction, and recognition motivations. For both genders, friends were the most important clothing information source, and price was the most important criterion for store selection. Significant differences were also found between genders. Female participants shopped significantly more often than males and had higher recreation clothing purchase motivation. Certain information sources, such as friends and magazines/books, had more influence over clothing purchase decisions made by females compared to males. Certain criteria such as product variety/availability and store display carried more weight for females than males when making a store selection. When impulse and nonimpulse shoppers were compared, significant differences were found in all the clothing behaviors examined in the study (i.e., clothing shopping frequency, expenditure, purchase motivations, information sources, store selection criteria). Educational and marketing implications are recommended.

Effect of surface treatment condition on interfacial degradation behavior in GFRP under acidic conditions

Interfacial degradation behavior of E-glass cloth reinforced vinyl ester resin under acidic conditions has been investigated. Specimens with different surface treatment conditions were prepared. Mode I fracture toughness tests were performed using DCB specimen, and the effect of surface treatment condition and immersion time on the crack propagation behavior is discussed. The crack propagation behavior changes as a function of the condition of the silane coupling agent and the immersion time due to the degradation of the interphase. A technique is proposed to evaluate the interfacial property. The change of fracture toughness of interphase and resin as a function of immersion time is studied by the crack propagation behavior and the fracture toughness of interphase and resin evaluated by this technique. The fracture toughness of interphase decreases rapidly with immersion in acidic solution.

Drape formation based on geometric constraints and its application to skirt modelling

Drape is a characteristic behaviour of flexible cloth, so it is important in modelling cloth. The paper introduces a novel method to model drape using a few shape parameters, predicted according to the pattern structure and mechanical properties of cloth. The technique is used to visualize the 3‐D drapeability of cloth and is then extended to simulation of a skirt. The general shape of a flared skirt of large deformation is predicted based on several shape parameters. Moreover, the constructed skirt model is used as pre‐draped initial shape for the popular physically‐based model – particle system. Kawabata Evaluation System (KES) plots of cloth are applied for accurate mechanical calculation. The simulated results show good agreement with actual cloth materials.

Diversity of Research in Textiles, Clothing, and Human Behavior: The Relationship Between What We Know and How We Know

In any field it is important to understand how knowledge is produced and how the production of knowledge affects what is known. Put another way, how have the conclusions drawn from research in textiles, clothing, and human behavior been structured by and affected by the research questions posed, the methods used to collect data, or even the training of its scholars? In this paper we offer a matrix of dimensions as an outline for analyzing research focusing on human behavior as it is related to textiles and clothing. Five broad dimensions are suggested for use in organizing research and in providing insight as to how knowledge in this field has been produced: (a) type of strategy used, (b) time frame, (c) origin of data elicited, (d) technique of data elicitation, and (e) qualitative or quantitative treatment of data. Each dimension is discussed, examples are provided, and related limitations are presented. Given the dimensions presented, we conclude with a discussion of how knowledge is shaped by how it is produced.

着装によって生起する恥ずかしさ意識に関する研究

This study aimed to clarify the difference in the consciousness of shame in dressing between the generations of female students and their mothers, and the relationship between their consciousness and clothing behaviors, The shame consciousness scale made by this study consists of 4 factors (1.body-emphasizing dressing, 2, distasteful dressing, 3.unsuitable dressing and 4.disgraceful dressing) and 20 items.An investigation was made in respects of 20 items for the consciousness of shame, 15 for the consciousness of dressing well and 20 for the consciousness of dressing norm in 159 female students and their mothers in December 1998 .Evaluation was made by 5-step rating method according to SD method.Analysis of the difference in the respective items between the two generations revealed that the mother's generation had a tendency to show higher points in the items for the consciousness of shame and those for the consciousness of dressing norm than the student's one . On the other hand, the latter generation showed higher points in the items for the consciousness of dressing well. in addition, the subjects that showed high points in the items for the consciousness of shame were apt to have higher points in those for dressing norm.

Mathematical Simulation of Heat and Moisture Transfer in a Human-Clothing-Environment System

A mathematical model has been developed to describe the dynamic heat and moisture transport behavior of clothing and its interaction with the human thermoregulation system under transient wear conditions. A modification of Gagge's two-node model is used to simulate the human physiological regulatory responses. In clothing, heat and moisture transport is coupled with the sorption or desorption of water vapor in the fibers and the associated energy changes. If the physical activity and ambient conditions are specified, the model can predict the thermoregulatory responses of the body, to gether with the temperature and moisture profiles of the clothing. Experimental mea surements with garments made from fibers with different levels of hygroscopicity are compared with predictions by the model. There is good agreement between prediction and experiment for skin and fabric temperatures and the relative humidity of the cloth ing microclimate.

A simple self-collision avoidance for cloth animation

This paper discusses the self-collision avoidance problem in simulating the dynamic behavior of deformable cloth. It is not an easy task to simulate realistically the response of cloth in various types of complicated self-collisions. In this paper, the bounding box technique in addition to ordinary prechecking for collision detection is used to avoid self-collision. Instead of avoiding self-collision of cloth triangles, we relax to avoid the collision of the bounding boxes of cloth triangles. Some constraints are enforced on the vertices of the cloth triangles to prevent their bounding boxes from penetrating in the direction of collision. The experimental results show that the relaxed self-collision avoidance method can create realistic cloth behavior and wrinkling formation processes. Since the types of interaction between bounding boxes are simple, our method is simple but robust in avoiding self-collisions.

Modeling and Simulation of a Falling Yarn with One End Fixed

This paper presents a model and simulation of yarn dynamics to predict the drape behavior of clothes by generalizing the model to fabrics. In the first part of this work, mathematical and mechanical theoretical bases are developed to attempt modeling the shape of a falling yarn with one end fixed. The equations describing the model are strongly interconnected and nonlinear. In the second part, a software implementation of the nonlinear system goes beyond the bounds of computing memory, requiring some simplifications. A series of simulations tests the influence of yarn parameters on this model.

Cycle safety among infant school children

Describes a small investigation into cycle safety with Key Stage 1 pupils. The investigation used the draw and write technique to find out what children in years 1 and 2 knew about safety in relation to riding bicycles. Finds that many children were aware of the need to wear a cycle helmet, and that some wrote about the need to wear knee pads, arm bands or special clothes. Suggests that a session such as that described could provide a useful way to work about keeping safe outdoors, road safety, protective clothing or safe behaviour, or as a useful one‐off session before a school holiday.

女子大生の衣生活行動と環境意識との関係

In this study the relation between consciousness of environmental protection and natural resource saving on daily clothing behavior, such as purchasing and wearing, was intended to clarify.For this purpose, the systematic survey was made for 1, 197 female university students at Kumamoto, Kobe and Tokyo.The results obtained are summarized as : 1) When the students were at purchase of clothing, they pay keen attention to“fashionability”of clothes, including, the coordination of clothing and well-matching and they choose clothes, which have good occasion of wearing and high frequency in wearing.This behavior is consistent with environmental protection.2) Examinees had high concerns about global circumstances problems, but they did show only low concern on exhaustion of natural resources.Majority of the students consider that action against environmental protection should be firstly taken by the government and also they recognized the urgent necessity of both public and personal efforts.3) Close correlation are observed between level of consciousness of environmental protection and of natural resource saving and some items of behavior at the purchase of clothing such as (1) trial wearingbefore making purchase decision (a2), (2) cordination with other clothes already keeping (a6), (3) clothing purpose of wearing (a7), (4) not buy beyond necessity (a13), (5) buy clothes of natural fiber (a16), (6) dead-stock clothes (a21) and (7) purchase clothes one after another (a23).4) At disposal of used clothes they did not recognize clothes as valuable resource.Generally, young students have comparatively low concern about exhaustion of natural resources caused by unduly excessive consumption and, especially the students who possess dead-stock clothes-and who enjoy the current fashion by buying clothes one after another, belong to a group of lower consciousness on circumstances and resource problems.These facts suggests strongly urgent necessity of education and enlightening activity for them about recognition of clothes as valuable resources.

Simulation of Procedures to Avoid Set Marks in Weaving Caused by Relaxation

Relaxation of warp yarns and fabric is one of the causes of set marks (starting places) in weaving. Loom manufacturers have developed experimental procedures to diminish these set marks, and this paper describes mathematical simulations of several such procedures. The simulations use a previously developed model for the viscoelastic behavior of warp yarn and cloth and for the cloth fell position. The aim of the paper is to provide a scientific background for anti-set mark procedures.

Towards simulating cloth dynamics using interacting particles

Reviews a new approach being developed for modelling the dynamic behaviour of cloth. This work extends the cloth‐particle static draping model of Breen and House to include dynamics, and extends constrained dynamics simulation techniques developed by Witkin, Gleicher and Welch to yield performance enhancements. Fundamental to this approach is a new hierarchical approximation algorithm for constrained dynamics simulation which, it is hoped, will reduce the computational time demands of the algorithm to near real‐time range.

Effect of humidity on the creasability of fabrics based on chemical and flax fibres

A method for assessing the effect of the relative humidity on an important index of flax-containing cloth which characterizes the stability of their shape, their creasability, was improved. It was found that creasing of pure flax samples with maximum atmospheric humidity (ϕ=98%) increases their ability to recover the initial shape in comparison to tests in normal conditions (ϕ=65%). The kinetics of the recovery angle of the sample after bending with compression are described by an exponential equation which can be used to predict the behavior of cloth after creasing in time. The calculated coefficients of the equation can be used to predict the relaxation processes of recovery of the cloth after creasing.

A Simple Beam Element, Large Displacement Model for the Finite Element Simulation of Cloth Drape

The behaviour of cloth draped about a human body form is simulated by modelling a garment as a mesh of simple beam finite elements, with geometric stiffness to account for large displacement behaviour, and carrying out a dynamic, time-stepping analysis to predict its behaviour as it falls from an initial horizontal position to the final draped position. The body form is based on anthropomorphic data produced by a shadow scanner. A novel scheme is introduced to model the contact between the cloth and the underlying body form. The model is used to provide data for an animated display which is found to simulate the drape of the garment sufficiently realistically for the garment designer's purposes.

Fracture and fatigue behavior of scrim cloth adhesively bonded joints with and without rivet holes

—Tensile and fatigue disbond propagation studies on scrim cloth structural adhesive lap joints without and with rivet holes were performed. The geometry of the rivet holes is similar to that in a fuselage part of an aircraft. The joints were cycled in tension-tension fatigue at a frequency of 3 Hz and a maximum load, below the linear limit of the joint, which was obtained from the tensile tests of similar joints. The disbond length at each corner of the joint was viewed using a travelling optical microscope attached to a video camera. It was found that the static-tensile behavior of both types of joints (without and with rivet holes) consists of three stages: a linear stage followed by a region of increased non-linearity and then a 'yield' region. It is within this yield region that the rivet holes affect the strength of the joint. Stress analysis of the disbond problem under static loading revealed a strong mixed mode between the opening and shear mode stress intensity factors for both types of joints. T...
