Geographically distributed engineers must collaboratively develop, build and test solutions to design-manufacture problems to be competitive in the global marketplace. Engineers operate in a distributed system in which separate entities communicate cooperatively—ideas and information requests are generated anywhere within the system, rapid turn-around is essential, and multiple projects must be handled simultaneously. In this paper we present a prototype platform-independent framework to integrate distributed and heterogeneous software resources to support the computationally intensive activities in the product realization process. This framework, PRE-RMI, is based on an experimental event-based communications model; it has been coded in Java and uses the RMI messaging system. We describe its usage in a distributed product realization environment, the Rapid Tooling TestBed. PRE-RMI is compared to a previous environment, called P2 that was based on Java Servlet technology. PRE-RMI is adaptable to different design processes, is modular and extensible, is robust to network and computing failures, and is far preferable to P2. Further, we demonstrate the successful integration of CAD, CAE, design, and manufacturing software tools and resources in this flexible distributed computing environment.

Abstract Increased competition is forcing product realization to change: to become faster and to leverage facilities and expertise, wherever they may be. Geographically distributed engineers must collaboratively develop, build and test solutions to design-manufacture problems to be competitive in the global marketplace. Software systems to support design and manufacturing activities must continuously evolve to accommodate rapid acquisition and use of knowledge throughout a global manufacturing enterprise. Engineers must operate in a distributed system in which separate entities communicate cooperatively — ideas and information requests can be generated anywhere within the system, rapid turn-around is essential, and multiple projects must be handled simultaneously. Thus we want to provide a platform-independent framework to integrate distributed and heterogeneous software resources to support the computationally intensive activities in the product realization process. In this paper, we present a prototype platform-independent framework based on an experimental event-based communications model and describe its usage in a distributed product realization environment, the Rapid Tooling TestBed.

Abstract We imagine a future in which geographically distributed engineers collaboratively develop, build, and test solutions to design-manufacture problems encountered in the product realization process. In this context, we want to provide a foundation to support the realization of industrial products for a global marketplace through distributed design and manufacture. Specifically, we want to provide a platform-independent framework to integrate distributed and heterogeneous software resources to support the computationally intensive activities in the product realization process, anchored in the philosophy of decision-based design. In this paper, we present a prototype platform-independent framework based on an experimental version, called P2, of the Sandia Product Realization Environment (PRE). We describe the implementation of this framework to design and prototype gear transmissions using commonly available software assets.

The term Product realization is usually used to describe the physical realization of a product in the product development cycle. Therefore, the term may or may not include conceptualization and design phases. Considering that product realization means bringing a product to reality, it is important to study the concept of reality to understand the role of conceptualization, design, and manufacturing in product realization. In this paper, the concept of reality is expanded to include the perceptual and virtual realities as integral parts of the product realization process. This paper discusses the three phases of realization and their interactions. It also addresses the key roles of conceptualization, design and manufacturability in the realization process. To illustrate the concepts, presented in the paper, some examples are included.

Virtual Reality (VR) technology holds promise as a virtual prototyping tool for mechanical assembly; however, several developmental challenges still need to be addressed before virtual prototyping applications can successfully be integrated into the product realization process. This paper describes the development of SHARP (System for Haptic Assembly & Realistic Prototyping), a portable VR interface for virtual assembly. SHARP uses physically-based modeling for simulating realistic part-to-part and hand-to-part interactions in virtual environments. A dual handed haptic interface for realistic part interaction using the PHANToM® haptic devices is presented. The capability of creating subassemblies enhances the application’s ability to handle a wide variety of assembly scenarios. Swept volumes are implemented for addressing maintainability issues and a network module is added for communicating with different VR systems at dispersed geographic locations. Support for various types of VR systems allows an easy integration of SHARP into the product realization process resulting in faster product development, faster identification of assembly and design issues and a more efficient and less costly product design process.

META-pipe is a complete service for the analysis of marine metagenomic data. It provides assembly of high-throughput sequence data, functional annotation of predicted genes, and taxonomic profiling. The functional annotation is computationally demanding and is therefore currently run on a high-performance computing cluster in Norway. However, additional compute resources are necessary to open the service to all ELIXIR users. We describe our approach for setting up and executing the functional analysis of META-pipe on additional academic and commercial clouds. Our goal is to provide a powerful analysis service that is easy to use and to maintain. Our design therefore uses a distributed architecture where we combine central servers with multiple distributed backends that execute the computationally intensive jobs. We believe our experiences developing and operating META-pipe provides a useful model for others that plan to provide a portal based data analysis service in ELIXIR and other organizations with geographically distributed compute and storage resources.

On the basis of mastering the general virtual design and manufacture, we combined with the data analysis of packing to construct the virtual package design and manufacturing, and the models we need can be build in external software, then we import these and would realize the interaction by Virtools. The interaction and simulation facilitate the validation and data modification of package design and manufacture feasible, and the precision of models, interactive space and relationship, simulation analysis and the key physical attributes of package design and manufacturing are the focused factors.

Abstract The process by which new products are brought to market — the product realization process, or PRP — can be introduced in engineering design education. In industry, the PRP has been evolving to concurrent engineering and product teams. The PRP includes components such as concept generation, analysis, manufacturing process development and customer interaction. Also, it involves the sequencing of the components and their connections which includes teamwork, project planning, meetings, reports and presentations. A capstone senior engineering project, along with classroom lectures and presentations can be structured to provide knowledge and experience to the students in many of the PRP components and the connections. This paper will give an overview of the PRP and a project/lecture structure at the author’s university. The instructor recently joined the academic ranks after years in industry with responsibility for directing product development and R&D and for leading product development teams.

Now, with the availability of 3-D ultrasound data, a lot of research efforts are being devoted to developing 3-D ultrasound strain elastography (USE) systems. Because 3-D motion tracking, a core component in any 3-D USE system, is computationally intensive, a lot of efforts are under way to accelerate 3-D motion tracking. In the literature, the concept of Sum-Table has been used in a serial computing environment to reduce the burden of computing signal correlation, which is the single most computationally intensive component in 3-D motion tracking. In this study, parallel programming using graphics processing units (GPU) is used in conjunction with the concept of Sum-Table to improve the computational efficiency of 3-D motion tracking. To our knowledge, sum-tables have not been used in a GPU environment for 3-D motion tracking. Our main objective here is to investigate the feasibility of using sum-table-based normalized correlation coefficient (ST-NCC) method for the above-mentioned GPU-accelerated 3-D USE. More specifically, two different implementations of ST-NCC methods proposed by Lewis et al. and Luo-Konofagou are compared against each other. During the performance comparison, the conventional method for calculating the normalized correlation coefficient (NCC) was used as the baseline. All three methods were implemented using compute unified device architecture (CUDA; Version 9.0, Nvidia Inc., CA, USA) and tested on a professional GeForce GTX TITAN X card (Nvidia Inc., CA, USA). Using 3-D ultrasound data acquired during a tissue-mimicking phantom experiment, both displacement tracking accuracy and computational efficiency were evaluated for the above-mentioned three different methods. Based on data investigated, we found that under the GPU platform, Lou-Konofaguo method can still improve the computational efficiency (17–46%), as compared to the classic NCC method implemented into the same GPU platform. However, the Lewis method does not improve the computational efficiency in some configuration or improves the computational efficiency at a lower rate (7–23%) under the GPU parallel computing environment. Comparable displacement tracking accuracy was obtained by both methods.
