The design methodologies and part shape algorithms for additive manufacturing (AM) are rapidly growing fields, proven to be of critical importance for the uptake of additive manufacturing of parts with enhanced performance in all major industrial sectors. The current trend for part design is a computationally driven approach where the parts are algorithmically morphed to meet the functional requirements with optimized performance in terms of material distribution. However, the manufacturability restrictions of AM processes are not considered at the primary design phases but at a later post-morphed stage of the part’s design. This paper proposes an AM design method to ensure: (1) optimized material distribution based on the load case and (2) the part’s manufacturability. The buildability restrictions from the direct energy deposition (DED) AM technology were used as input to the AM shaping algorithm to grant high AM manufacturability. The first step of this work was to define the term of AM manufacturability, its effect on AM production, and to propose a framework to estimate the quantified value of AM manufacturability for the given part design. Moreover, an AM design method is proposed, based on the developed internal stresses of the build volume for the load case. Stress tensors are used for the determination of the build orientation and as input for the part morphing. A top-down mesoscale geometric optimization is used to realize the AM part design. The DED Design for Additive Manufacturing (DfAM) rules are used to delimitate the morphing of the part, representing at the same time the freeform mindset of the AM technology. The morphed shape of the part is optimized in terms of topology and AM manufacturability. The topology optimization and AM manufacturability indicator (TMI) is introduced to screen the percentage of design elements that serve topology optimization and the ones that serve AM manufacturability. In the end, a case study for proof of concept is realized.

ABSTRACTBeyond being simply positive or negative, beneficial or inhibitory, microbial interactions can involve a diverse set of mechanisms, dependencies and dynamical properties. These more nuanced features have been described in great detail for some specific types of interactions, (e.g. pairwise metabolic cross-feeding, quorum sensing or antibiotic killing), often with the use of quantitative measurements and insight derived from modeling. With a growing understanding of the composition and dynamics of complex microbial communities for human health and other applications, we face the challenge of integrating information about these different interactions into comprehensive quantitative frameworks. Here, we review the literature on a wide set of microbial interactions, and explore the potential value of a formal categorization based on multidimensional vectors of attributes. We propose that such an encoding can facilitate systematic, direct comparisons of interaction mechanisms and dependencies, and we discuss the relevance of an atlas of interactions for future modeling and rational design efforts.

Seismic Design Method

The current seismic design rule on piping assumes elastic analysis without the effect of response reduction due to plasticity, although some degree of plasticity is allowed in its allowable limits. Damping for the seismic design analysis is conservatively determined depending on the number of supports and thermal insulation conditions. These conservative assumptions lead to large amount of design margin. Based on such recognition, to provide a more rational seismic design method, a new Code Case for seismic design of piping is now under development in the framework of JSME Nuclear Codes and Standards as an alternative rule to the current design rule. The Code Case provides detailed inelastic analysis with using shell or solid FEA models as a more rational method. Simplified analysis with an additional damping taking the response reduction due to plasticity into account is now under consideration to incorporate the convenience in design. In this study, a series of analysis was made to see the adequacy of the simplified inelastic analysis. Design margins contained in the current design analysis method composed of response spectrum analysis and stress factors was quantitatively assessed in the view point of additional damping.

The Way

This journal’s editorial statement is clear that political discourse should be studied not only as regards parliamentary type politics. In this introduction we argue precisely for the need to pay increasing attention to the way that political ideologies are infused into culture more widely, in entertainments media, software, administrative processes, children’s apps, healthcare and even office furniture design. We point to the way that there have been massive shifts away from traditional state forms of politics to the rule of neoliberalism and the power of the corporation which, like the former regime of power, requires meanings and identities which can hold them in place. We explain the processes by which critical multimodal discourse analysis can best draw out this ideology as it is realized through different semiotics resources.

A ship general design platform is established in order to satisfy the requirement integrating design, analysis and optimization in ship design process. A design-analysis unified connected model is developed based on digital ship idea and a ship general design platform frame system is formed based on the template technology. In the preliminary application process, a design tool database and an applicative template database are established. That the reliability proves to be good is significant for promoting traditional design method and improving design efficiency.

Bicycle Design

The design method on bicycle’s functional elements proposed by this research is based on analysis on the winning work in the Global Bicycle Design Competition. Via analyzing its creative design on functional elements, our study is aimed to establish a creative design method on bicycle for designers to develop lots of creative ideas at the concept development stage. This research is divided into three stages, including analysis on bicycle’s creative design elements, construction of creative design method flow on bicycle’s functional elements, and case study on design prototype. For analysis on bicycle’s creative design elements, we have come up with a symbol table of bicycle’s creative functional elements (CFEs). As to construction of creative design method flow on bicycle’s functional elements, we first asked the designer to describe his/her design theme, and then picked bicycle’s CFEs according to the contents described. After CFEs were picked, we then conducted the space position arrangement of functional element symbols. Based on designer’s requirements, we produced several kinds of space arrangements on CFEs, and then we designed a new bicycle by referring to the symbol table of bicycle’s CFEs acquired. In the final step, we followed the flowchart of bicycle’s CFEs constructed by this research, and proceeded a case study prototype design.

And Coping

With their increasing emphasis on the importance of hands-on practice and gaining experience, the fields of engineering-design research and education appear to be entering a human-focused transition other fields like economics and decision making have emerged from in the recent past. In addition to the original, modernism-rooted desire for a rational science of design modelled on the natural sciences, this delay may be due the inherently strong association of engineering with science – i.e., ‘applied science.’ This research investigated whether there may instead be a science to the human involvement in design, of the human behaviours that often appear in actual engineering design practice. It surveyed published empirical studies in psychology, child development and other social and life sciences – as well as those within design research itself. Of particular interest were the designer behaviours and activities which did not follow the prescriptions of – or were prescribed against by – the traditional, rational-design methods: visualization, single-solution conjecturing, and intuition. Results from this survey showed comprehensively that environmental interactions and authentic design experiences activate latent design abilities and coping mechanisms that may be difficult to obtain otherwise. Without such interaction and the gaining of experience there can be no designing, so essentially design is a wholly human phenomenon. Rather than follow the rational-design method and prescribe against these design-enabling behaviours, then, it appears that a better pedagogical approach is to allow them to develop and mature – and let design novices become the experts they were meant to be.
