Scenarios can help individuals, communities, corporations and nations to develop a capacity for dealing with the unknown and unpredictable, or the unlikely but possible. A range of scientific methods for developing scenarios is available, but we argue that they have limited capacity to investigate complex social-ecological futures because: 1) non-linear change is rarely incorporated and: 2) they rarely involve co-evolutionary dynamics of integrated social-ecological systems. This manuscript intends to address these two concerns by applying the method of science fiction prototyping to developing scenarios for the future of global fisheries in a changing global ocean. We used an empirically informed background on existing and emerging trends in marine natural resource use and dynamics to develop four 'radical ocean futures,' incorporating and extrapolating from existing environmental, technological, social and economic trends. We argue that the distinctive method as applied here can complement existing scenario methodologies and assist scientists in developing a holistic understanding of complex systems dynamics. The approach holds promise for making scenarios more accessible and interesting to non-academics and can be useful for developing proactive governance mechanisms.

The construction industry is ripe for disruption through innovative solutions that provide added productivity. Equipment manufacturers are attempting to disrupt their industry with investments in autonomy, electrification and product-service system business models. Designing solutions that will operate in completely new systems or modify an existing complex system require new approaches to address the uncertainty of system impacts. An iterative approach can help tackle ambiguity through cyclical validation of design decisions. Data mining in each cycle adds a quantitative dimension to the rationale of decision making, but data is sparse and difficult to collect in parallel with design of theoretical product-service systems operating in future scenarios. This can be combated using experiential prototyping techniques to design flexible infrastructure that supports contextualized data gathering in a variety of focused design sprints using Design, Build and Test approach. The intricacy of designing innovative solutions to increase productivity in the construction industry can be untangled by framing aspects of the problem in small sprints and testing them in a contextualized setting built to generate functional data to drive design.

Using a case study methodology to exploring an ambitious experimental combination of a construction equipment manufacturer’s products tailored to provide exponential increases in efficiency and reductions in CO2. The products and system represent a relevant example of new technology being the foundation upon which a functional offering IPSS can be designed. The researcher constructed a scaled down functional experiential prototype reflecting a full scale experimental all electric quarry site in under operation outside of Goteborg, Sweden. The prototype site represented the primary equipment and system functionality, to act as a boundary object around which relevant stakeholders both internal and external could share the vision of an electric autonomous future. This was confirmed via observation at an event where the scale site was used for this purpose and verified with follow up interviews to dig deeper into the impact this tangible representation could have in increasing the perceived viability of the full scale technology’s potential on display thousands of miles from the event.
This article presents a novel methodology to design swash plate type axial piston machines based on computationally based approach. The methodology focuses on the design of the main lubricating interfaces present in a swash plate type unit: the cylinder block/valve plate, the piston/cylinder, and the slipper/swash plate interface. These interfaces determine the behavior of the machine in term of energy efficiency and durability. The proposed method couples for the first time the numerical models developed at the authors’ research center for each separated tribological interface in a single optimization framework. The paper details the optimization procedure, the geometry, and material considered for each part. A physical prototype was also built and tested from the optimal results found from the numerical model. Tests were performed at the authors’ lab, confirming the validity of the proposed method.

In information design education, we strive to find methods that provide students with opportunities to explore different ways of learning and designing. We seek to support development of contextual competences that will be helpful in navigating an unknown future of design in society. A challenge in today's design education is to formulate and use methods that support design students in developing competencies in the space between basic form training and context-rich training. The aim of this study was to evaluate prototyping exercises in design education where the focus was in that in-between space. The study is based on 33 prototyping workshops done between 2008 and 2015 and involving 160 students and two design teachers. Four different approaches to prototyping exercises are described, examined and evaluated: "spatial prototyping," "multi-material prototyping," "physical prototyping," and a mix between the latter two, "physical multi-material prototyping." The results show that the prototyping exercises did support the learning of diverse competencies in the in-between space of basic form training and context training. However, the exercises were also counterproductive and met with different kinds of resistance. The results of the study invite to a dialogue on how different prototyping techniques can stimulate learning in relation to future design competences.

Engineered nanoparticles for biomedical applications requireincreasing effectiveness in targeting specific cells while preservingnon-target cell’s safety. We developed a surface proteomicsmethod for a rapid and systematic analysis of the interphasebetween the nanoparticle protein corona and the targeting cellsthat could implement the rapid prototyping of nanomedicines.Native nanoparticles entering in a protein-rich liquid mediaquickly form a macromolecular structure called protein corona.This protein structure defines the physical interaction betweennanoparticles and target cells. The surface proteins compose thefirst line of interaction between this macromolecular structureand the cell surface of a target cell. We demonstrated that SUSTU(SUrface proteomics, Safety, Targeting, Uptake) provides aqualitative and quantitative analysis from the protein coronasurface. With SUSTU, the spatial dynamics of the protein coronasurface can be studied. Data from SUSTU would ascertain thenanoparticle functionalized groups exposed at destiny that couldcircumvent preliminary in vitro experiments. Therefore thismethod could implement the analysis of nanoparticle targetingand uptake capability and could be integrated into a rapidprototyping strategy which is a major challenge in nanomaterialscience. Data are available via ProteomeXchange with identifierPXD004636.

High frequency power electronics utilizing wide-band gap semiconductor devices imposes more stringent requirements for highly accurate extraction of parasitics of power electronics systems in a wide frequency range. This paper presents the state-of-the-art modeling approaches used to predict the electromagnetic behavior of power electronic systems and components in terms of accuracy and computational cost. The potential of the Partial Element Equivalent Circuit (PEEC) technique for virtual prototyping of power electronic systems is assessed. The main advantage of this numerical technique is its capability for direct coupling between the circuit and electromagnetic domains provided by the PEEC meshing of three-dimensional geometries in partial elements. The aim of this paper is to provide a more comprehensive understanding of PEEC-based modeling for power electronics packaging.

Including children in the design of technologies that will have an impact on their daily lives is one of the pillars of user-centered design. Educational robots are an example of such a technology where children’s involvement is important. However, the form in which this involvement should take place is still unclear. Children do not have a lot of experience with educational robots yet, while they do have some ideas of what robot could be like from popular media, such as BayMax from the Big Hero 6 movie. In this paper we describe two pilot studies to inform the development of an elicitation method focusing on form factors; a first study in which we have asked children between 8 and 15 years old to design their own classroom robot using a toolkit, the Robo2Box, and a second study where we have compared the use of the Robo2Box toolkit and clay as elicitation methods. We present the results of the two studies, and discuss the implications of the outcomes to inform further development of the Robo2Box for prototyping classroom robots by children.

BACKGROUND: Current guidelines for accessing graphs non-visually are based on giving access to underlying tabular data and reading the values one by one. When data sets are large, it becomes impossible to get an overview.OBJECTIVE: This work presents a proof-of-concept of automated audio description of data sets up to 100 data points that can be used by persons with visual impairment or persons who for other reasons are unable to use their visual attention for data access.METHODS: A pilot study was conducted to elicit guidelines for oral chart descriptions, after which lo-fi and hi-fi prototypes were designed. Visually impaired and sighted users were involved throughout the process.RESULTS: The pilot study pinpointed important issues of oral chart descriptions and provided input for a lo-fi-prototype with three variants. The lo-fi-prototype singled out the most successful way of describing the charts based on which a hi-fi prototype for large data sets was created and tested.CONCLUSIONS: The results of the hi-fi tests are promising. Participants listened 1-2 times to the descriptions and were able to discuss details in the data. Thus, the initial guidelines and the following design process provided the necessary information to create a successful proof-of-concept.
