  • Rigidity Analysis of Protein Molecules
    • Authors: Shahbazi Z; Demirtas A.
      Abstract: Intrinsic flexibility of protein molecules enables them to change their 3D structure and perform their specific task. Therefore, identifying rigid regions and consequently flexible regions of proteins has a significant role in studying protein molecules' function. In this study, we developed a kinematic model of protein molecules considering all covalent and hydrogen bonds in protein structure. Then, we used this model and developed two independent rigidity analysis methods to calculate degrees of freedom (DOF) and identify flexible and rigid regions of the proteins. The first method searches for closed loops inside the protein structure and uses Grübler–Kutzbach (GK) criterion. The second method is based on a modified 3D pebble game. Both methods are implemented in a matlab program and the step by step algorithms for both are discussed. We applied both methods on simple 3D structures to verify the methods. Also, we applied them on several protein molecules. The results show that both methods are calculating the same DOF and rigid and flexible regions. The main difference between two methods is the run time. It's shown that the first method (GK approach) is slower than the second method. The second method takes 0.29 s per amino acid versus 0.83 s for the first method to perform this rigidity analysis.

  • Task-Oriented Adaptive Maintenance Support System
    • Authors: Huang Y; Wang X, Gardoni M, et al.
      Abstract: Technical manuals for complex systems like automobiles, airplanes, and machine tools, often consist of a huge amount of documentation containing disassembling, assembling instructions and drawings of parts, subassemblies, and exploded views. So it is difficult for users to find a piece of information they need amongst these huge amount of documentations. In order to support maintenance implementation process effectively, a task-oriented adaptive maintenance support (TOAMS) system is designed to provide an intelligent, adaptive electronic support for maintaining complex equipment according to user profiles and their work in hand. By building user model, task model, and product model, document model is configured by multiview and some pieces of semantic information are added into data modules. An agent based software application is being developed to support and allow a systematic utilization of the “adaptive response” by integrating it into the daily work of the technician. An application is presented to show the applicability of our method.

  • Problem Map: An Ontological Framework for a Computational Study of Problem
           Formulation in Engineering Design
    • Authors: Dinar M; Danielescu A, MacLellan C, et al.
      Abstract: Studies of design cognition often face two challenges. One is a lack of formal cognitive models of design processes that have the appropriate granularity: fine enough to distinguish differences among individuals and coarse enough to detect patterns of similar actions. The other is the inadequacies in automating the recourse-intensive analyses of data collected from large samples of designers. To overcome these barriers, we have developed the problem map (P-maps) ontological framework. It can be used to explain design thinking through changes in state models that are represented in terms of requirements, functions, artifacts, behaviors, and issues. The different ways these entities can be combined, in addition to disjunctive relations and hierarchies, support detailed modeling and analysis of design problem formulation. A node–link representation of P-maps enables one to visualize how a designer formulates a problem or to compare how different designers formulate the same problem. Descriptive statistics and time series of entities provide more detailed comparisons. Answer set programming (ASP), a predicate logic formalism, is used to formalize and trace strategies that designers adopt. Data mining techniques (association rule and sequence mining) are used to search for patterns among large number of designers. Potential uses of P-maps are computer-assisted collection of large data sets for design research, development of a test for the problem formulation skill, and a tutoring system.

  • Competitive Usability Analysis of Immersive Virtual Environments in
           Engineering Design Review
    • Authors: Satter K; Butler A.
      Abstract: A competitive usability study was employed to measure user performance and user preference for immersive virtual environments (VEs) with multimodal gestural interfaces when compared directly with nonstereoscopic traditional CAD interfaces that use keyboard and mouse. The immersive interfaces included a wand and a data glove with voice interface with an 86 in. stereoscopic rendering to screen; whereas, the traditional CAD interfaces included a 19 in. workstation with keyboard and mouse and an 86 in. nonstereoscopic display with keyboard and mouse. The context for this study was a set of “real world” engineering design scenarios. These design scenarios include benchmark 1—navigation, benchmark 2—error finding and repair, and benchmark 3—spatial awareness. For this study, two populations of users were employed, novice (n = 15) and experienced (n = 15). All users experienced three successive trials to quantify the effects of limited learning. Statistically based comparisons were made using both parametric and nonparametric methods. Conclusions included improved capability and user preference for immersive VEs and their interfaces were statistically significant for navigation and error finding/repair for immersive interfaces.

  • Graph Based Method and Tool for Complete and Selective Disassembly Time
           Estimation in Early Design
    • Authors: Hu Y; Srinivasan R, Spoll J, et al.
      Abstract: The goal of this research is to develop a method and tool (a) to estimate disassembly time automatically from early embodiment design based CAD model and (b) to provide design suggestions to improve product disassemblability. Disassembly is a critical process in the end-of-life (EOL) stage of a product. It is usually followed by sorting and then by material recovery for recycling or part recovery for reuse or remanufacturing. Manual estimation of disassembly time, through physical prototype disassembly or through Boothroyd and Dewhurst system, is time consuming and is not applicable in the early design stage. In this research, graph based data structures and related metrics are utilized to estimate complete and selective disassembly time at embodiment design stage. Selective disassembly is important when a single part of subassembly is to be recovered while the rest of the product is to be discarded. Selective disassembly time is estimated by merging particular nodes in assembly and bipartite graph and then recomputing the graph metrics. The method and algorithm presented in this paper is implemented using SolidWorks application programming interface (API) in Visual C#. Results are compared with the results obtained by Boothroyd and Dewhurst method, the error range is reasonable.

  • Experimental Study of an Airplane Accident Evacuation/Rescue Simulation
           Using Three-Dimensional Kinematic Digital Human Models
    • Authors: Kakizaki T; Endo M, Urii J.
      Abstract: The 3D mass evacuation simulation of an airplane accident is experimentally verified. Evacuee motion has been experimentally investigated by building a test field that emulates the interior of an actual regional airliner with a capacity of approximately 100 passengers. The experiment results indicate that the evacuation time tends to be affected by the number of passengers and the evacuee guidance at the emergency exit. The results also indicate that any evacuation delay in exiting by individual passengers only slightly affects the total evacuation time because of evacuee congestion in the aisles. Moreover, the importance of evacuation guidance notification was investigated based on the evacuation-order variance. Finally, the experimental results were compared to the corresponding simulation results. Simulations using appropriate evacuee walking speeds can provide valid evacuation times, which are the most important factor in designing evacuation drills. Consequently, these results should be applied to existing 3D simulations using precise kinematic digital human (KDH) models for more accurate mass evacuation/rescue simulations.

  • A Publishing Method of Lightweight Three-Dimensional Assembly Instruction
           for Complex Products
    • Authors: Geng J; Zhang S, Yang B.
      Abstract: In order to accurately guide on-site workers to quickly accomplish the assembly job of complex products, and reduce the deployment cost of assembly instruction, we propose a publishing method of lightweight 3D assembly instruction for complex products. In this paper, the key frames of assembly motion and the 3D technical annotations in the lightweight model are mapped to the time-based assembly process. Then, the annotated lightweight model and assembly process information are integrated and published into a single 3D assembly instruction document. An assembly instruction publishing example of satellite antenna feed component shows that the lightweight 3D assembly instruction is well instructive and affordable because it provides the interactive simulation of assembly process and time-based display of assembly technical annotations without using expensive computer-aided design (CAD) systems, graphics workstations, or virtual reality equipments. This method gives a full play to the advantages of model-based definition technology and lightweight model, and fills the gap between the process planning and the instruction publishing in the 3D virtual manufacturing environment.

  • Quantifying Product Favorability and Extracting Notable Product Features
           Using Large Scale Social Media Data
    • Authors: Tuarob S; Tucker CS.
      Abstract: Some of the challenges that designers face in getting broad external input from customers during and after product launch include geographic limitations and the need for physical interaction with the design artifact(s). Having to conduct such user-based studies would require huge amounts of time and financial resources. In the past decade, social media has emerged as an increasingly important medium of communication and information sharing. Being able to mine and harness product-relevant knowledge within such a massive, readily accessible collection of data would give designers an alternative way to learn customers' preferences in a timely and cost-effective manner. In this paper, we propose a data mining driven methodology that identifies product features and associated customer opinions favorably received in the market space which can then be integrated into the design of next generation products. Two unique product domains (smartphones and automobiles) are investigated to validate the proposed methodology and establish social media data as a viable source of large scale, heterogeneous data relevant to next generation product design and development. We demonstrate in our case studies that incorporating suggested features into next generation products can result in favorable sentiment from social media users.

  • Integrated, Synchronous Multi-User Design and Analysis
    • Authors: Briggs JC; Hepworth AI, Stone BR, et al.
      Abstract: An integrated multi-user system for synchronous design and analysis improves collaboration and concurrent engineering across multiple engineering disciplines. This approach allows all members of a multidisciplinary team (i.e., a team made up of designers and structural analysts) to access the same shared model over a computer network and synchronously contribute to the model in real-time. Data for both design and analysis are directly based on the same mathematical representation of the geometry, eliminating the need for model translation between disciplines. All data are stored on a central server which allows simultaneous access by multiple users. Each user views and operates on the model in a way specific to his or her discipline. Updates to the shared model are seen in real-time. This system enables an enhanced parallel product development workflow, since users from multiple disciplines can simultaneously contribute to the same engineering model. A simple implementation of an integrated multi-user design and analysis system was developed to demonstrate this method. Preliminary results from two experiments suggest a reduction in the amount of time required to perform design and analysis operations when compared with traditional, single-user approaches. Future research is suggested.
