This work explores an additive-manufacturing-enabled combination-of-function approach for design of modular products. AM technologies allow the design and manufacturing of nearly free-form geometry, which can be used to create more complex, multi-function or multi-feature parts. The approach presented here replaces sub-assemblies within a modular product or system with more complex consolidated parts that are designed and manufactured using AM technologies. This approach can increase the reliability of systems and products by reducing the number of interfaces, as well as allowing the optimization of the more complex parts during the design. The smaller part count and the ability of users to replace or upgrade the system or product parts on-demand should reduce user risk, life-cycle costs, and prevent obsolescence for the user of many systems. This study presents a detailed review on the current state-of-the-art in modular product design in order to demonstrate the place, need and usefulness of this AM-enabled method for systems and products that could benefit from it. A detailed case study is developed and presented to illustrate the concepts.

This paper shall present the details of recently conducted studies that examine the criteria for success and the future of product development in the automotive industry. A majority of the forecasts predict increasing globalization, cost containment, dependence on suppliers and increase in electronics content. Correspondingly, OEM’s and suppliers are adopting and implementing CAD and PLM strategies that shall be explored together with the ideal PLM strategy for OEM’s and suppliers.

Building energy consumption accounts for 30%–45% of the global energy demand. With an ever-increasing world population, it has now become essential to minimize the energy consumption for the future of the environment. One of the most crucial aspects in this regard is the utilization of sensing and environmental monitoring technologies in buildings as these technologies provide stakeholders, such as owners, designers, managers, and occupants, with important information regarding the energy performance, safety and cost-effectiveness of the building. With the global sensors market value predicted to exceed $190 billion by 2021 and the number of sensors deployed worldwide forecasted to reach the ‘1 Trillion’ mark by 2025, a state-of-the-art review of various commercially-viable sensor devices and the wide range of communication technologies that complement them is highly desirable. This paper provides an insight into various sensing and environmental monitoring technologies commonly deployed in buildings by surveying different sensor technologies, wired and wireless communication technologies, and the key selection parameters and strategies for optimal sensor placement. In addition, we review the key characteristics and limitations of the most prominent battery technologies in use today, different energy harvesting sources and commercial off-the-shelf solutions, and various challenges and future perspectives associated with the application of sensing and environmental monitoring technologies within buildings.

This work explores an additive-manufacturing-enabled combination-of-function approach for design of modular products. AM technologies allow the design and manufacturing of nearly free-form geometry, which can be used to create more complex, multi-function or multi-feature parts. The approach presented here replaces sub-assemblies within a modular product or system with more complex single parts that are designed and manufactured using AM technologies. This approach can increase the reliability of systems and products by reducing the number of interfaces, as well as allowing the optimization of the more complex parts during the design. The smaller part count and the ability of users to replace or upgrade the system or product parts on-demand should reduce user risk, life-cycle costs, and prevent obsolescence for the user of many systems.

Abstract As manufacturers are becoming responsible for their products when they reach the end of their operational lives, the dismantling of products has emerged as one of the serious part of this exercise. In situations involving integrated design principles, certain assembly procedures or joining techniques can make it very difficult to disassemble a product and to separate materials into non-contaminated groups. The strategy is to begin including design for disassembly guidelines in the current product design processes. Design for Disassembly (DFD) is a design philosophy that requires consideration to be given for a product or a part, even after it is in service. The inclusion of procedures for design for disassembly, recyclability and re-manufacture will save resources by prolonging the useful life of product. The paper initially examines the current state of the art in the area of Design for Disassembly and looks at the existing methodologies that are applicable to product design. A new methodology based on a combination of charts based on damage rating, tool rating, re-use rating and access-area rating is proposed. The methodology is compared with the existing methods and evaluated for various situations in aerospace industry.

Computation-intensive design problems are becoming increasingly common, especially for large-size manufacturers such as those in the aerospace, automotive, and electronics industries. The computation burden is often caused by expensive analysis and simulation processes. Approximation or metamodeling techniques are often used to model these computation-intensive processes in order to improve efficiency. This work will review the current state-of-the-art on metamodeling-based techniques in support of product design. The review is organized from a practitioner’s perspective according to the role of metamodeling in supporting design. Challenges and future development of metamodeling will also be analyzed and discussed.

This paper is an introduction to behavioral genetics for researchers and practioners in language development and disorders. The specific aims are to illustrate some essential concepts and to show how behavioral genetic research can be applied to the language sciences. Past genetic research on language-related traits has tended to focus on simple etiology (i.e., the heritability or familiality of language skills). The current state of the art, however, suggests that great promise lies in addressing more complex questions through behavioral genetic paradigms. In terms of future goals it is suggested that: (a) more behavioral genetic work of all types should be done—including replications and expansions of preliminary studies already in print; (b) work should focus on fine-grained, theory-based phenotypes with research designs that can address complex questions in language development; and (c) work in this area should utilize a variety of samples and methods (e.g., twin and family samples, heritability and segregation analyses, linkage and association tests, etc.).
