Mass customization is a new manufacturing trend in which mass-market products (e.g., apparel) are quickly modified one at a time based on customers' needs. It is an effective competing strategy for maximizing customers' satisfaction and minimizing inventory costs. An automatic body measurement system is essential for apparel mass customization. This paper introduces the development of a body scanning system, body size extraction methods, and body modeling algorithms. The scanning system utilizes the multiline triangulation technique to rapidly acquire surface data on a body, and provides accurate body measurements, many of which are not available with conventional methods. Cubic B-spline curves are used to connect and smooth body curves. From the scanned data, a body form can be constructed using linear Coons surfaces. The body form can be used as a digital model of the body for 3-D garment design and for virtual try-on of a designed garment. This scanning system and its application software enable apparel manufacturers to provide custom design services to consumers seeking personal-fit garments.

Software engineering is largely a human-based activity despite all computer support. humans, however have their individual motives, fears and imponderabilities. Process models and their necessary support in form of a software engineering environment have a high pervasiveness and impact on the software development process and the people working with it. For this reason individuals feel more strongly about any technology change in this area. human factors gain a strong influence and often impede the successful introduction of such a technology. In this paper we take a human centered perspective and describe, from the viewpoint of an individual developer soft factors hindering successful adoption of process models. We classify these soft factors according to the relation a developer has with respect to his/her social environment.
The fundamental modeling differences between hardware and software modeling can be thought of as reasoning about connectedness vs. reasoning about interleaved (shared) access to resources. A natural design hierarchy f...

A complete 3D virtual model of the major structures of the ear responsible for the transfer of sound was constructed using computer-aided design (CAD) software. The model was created from the digital images of histological sections of a human temporal bone. These images were enhanced, resized, and aligned with respect to four fiducial marks using photo management software. Each structure of the ear including the external ear canal, middle ear, and cochlea was extracted from the sections and arranged to produce a complete 3D model within the SolidWorks environment. The individual structures can then be combined to produce a complete model of the entire human ear. The model will be used for analysis and further advanced modeling techniques.

Detailed kinetic and thermodynamic modeling and simulation of the chemical reactions are the valuable contributions at design stage of a new explosion mitigation engineering system, during the official explosion accident investigations, and for the academic studies of the complex explosion phenomena. In Moscow Institute of Physics and Technology along with the traditional experimental laboratory works in chemical kinetics and thermodynamics an integration of computer-aided labs into curricula of the second and third course students was started two years ago.. Two core sets of digital laboratory works, connected with the combustion and explosion phenomena, were developed as supplements for the general chemical thermodynamics course and advanced chemical kinetics course. Computer labs are based on "Chemical Workbench" - software system for complete cycle of computer-aided reaction engineering. "ChemBench" reaction simulation environment was developed by Kinetic Technologies (software provider) in cooperation with Russian Research Center "Kurchatov Institute". Report is focused on motivation and the goals of computer-aided laboratory works. Benefits of using these "virtual" or "digital research tools" in teaching of the chemical kinetics and thermodynamic aspects of combustion effects are shown. Their relations and drawbacks in comparison to ordinary "real" experimental installations and apparatuses are discussed.
The project described in this paper is directed at the goal of providing timely information for material selection and alloy design. The material selection process - whether it involves new or existing materials - can...

digitalhuman Models (DHM) are used for various applications in the design process of workplaces and human-machine interfaces. Due to the realistic appearance of DHMs, high resolution of CAD-systems, and the results of various validation studies, the DHMs suggest high validity and precision to the user. For static applications, advanced statistic methods have been implemented to facilitate a valid prediction of anthropometric body dimensions, their variability, and body posture. In recent years, functionality for modeling dynamic behavior has been added to facilitate movement simulation and analysis in the time domain. In this study the aspects of motion and movement simulation are analyzed, and inaccuracies of motion simulation of a DHM are interpreted. At motions with low restriction level it was found that ostensive realistic motions showed large differences for the position prediction of parts of the body, and for motions with high restriction level non-realistic simulations occurred.

This paper highlights a new design paradigm: a shift from traditional digitalhumanmodeling methods employing one-dimensional measures to an advanced operator workstation design tool using multi-dimensional data in a fully-immersive, Virtual Reality (VR) environment. This advanced tool enables human factors and other design decisions to be made in a virtual, three-dimensional space, allowing accurate visualization of relationships among human population landmark data and workstation geometry. Whole-body surface scans from approximately 4,500 civilians obtained through the CAESAR project, and 3D anatomical landmark data collected from subjects seated in John Deere seats are used by this tool. Specific methods of data interaction are described. The advantages of immersive applications over traditional desktop simulations, as well as the rationale, development, and implementation of this advanced operator workstation design tool are presented.
We report on some of the advantages tangible interaction can bring to chemistry education. We describe the realisation of a tangible user interface (TUI) called Augmented Chemistry (AC). A set of interactive tools wor...

We discuss the gap we experience in an industrial design path of high-speed packet switches. As bandwidth demand exceeds progress in CMOS technology, system architects are forced to abandon familiar design solutions and make fundamental changes to their architectures at an increasingly faster pace. We investigate design methods to decrease the risk of such changes and to provide a structured and confident transition from conceptual system-level models to hardware descriptions. It appears that the design gap is caused by differences between language primitives and underlying concepts of system-level design languages and hardware description languages. We substantiate the need for expressive system-level modeling concepts and show that the gap is actually caused by a fundamental interpretation mismatch between models and descriptions. Based on a comparison of existing system-level synthesis methods with the interpretation gap, we propose to decrease the gap by using modeling patterns.
