Visual Sensemaking of Massive Crowdsourced Data for Design Ideation
Authors: He Yuejun , Camburn Bradley , Luo Jianxi , Yang Maria C. , Wood Kristin L. 
Published: July 2019

AbstractTextual idea data from online crowdsourcing contains rich information of the concepts that underlie the original ideas and can be recombined to generate new ideas. But representing such information in a way that can stimulate new ideas is not a trivial task, because crowdsourced data are often vast and in unstructured natural languages. This paper introduces a method that uses natural language processing to summarize a massive number of idea descriptions and represents the underlying concept space as word clouds with a core-periphery structure to inspire recombinations of such concepts into new ideas. We report the use of this method in a real public-sector-sponsored project to explore ideas for future transportation system design. Word clouds that represent the concept space underlying original crowdsourced ideas are used as ideation aids and stimulate many new ideas with varied novelty, usefulness and feasibility. The new ideas suggest that the proposed method helps expand the idea space. Our analysis of these ideas and a survey with the designers who generated them shed light on how people perceive and use the word clouds as ideation aids and suggest future research directions.
Analysing the Relevance of Serious Game Elements for Effectively Teaching Innovation Processes

Published: July 2019

AbstractSerious games (SGs) as a new educational format have gained interest among many scholars from diverse fields. SGs seem to be useful tools for teaching innovation processes (IP) as they guarantee intrinsic motivation and provide situated learning. So far, there is no guideline on designing IP games and lowering their development time while ensuring their effectiveness. To fill this gap, we should first analyse the existing IP games with evaluation methods and synthesise their commonalities. Numerous methods have been put forward in the literature to assess digital SGs; however, most of the SGs for IP are board games. That is why we explore in this paper the use of Serious Game Design Assessment (SGDA) framework to analyse IP board games. According to the case study on an open innovation board game, we suggest applying this method to examine the a priori relevance of game elements (components that make up a game system). Moreover, we make recommendations to complement the SGDA framework with Game and Learning Mechanics, and real-world information. This contribution should help designers transform traditional educational supports into serious board games for teaching IP.

Published: July 2019

AbstractThe early (pre-requirement) stages of product development can provide relevant insights into the creative design process. At these stages, the communication of ideas during the prototyping process can serve as a rich source for information. In this paper, we attempt to document physical prototypes generated during the design process. We describe the design and preliminary testing of Protobooth Oulu: a system that can be used for documenting the process of prototyping products through capturing process output 'snapshots' in time at the early stages of product development. Our primary motivation is to facilitate documentation and reflection from an educational perspective. We tested the system during a course on digital fabrication in a FabLab environment, where ten teams documented their coursework over the course of six weeks. Managing to capture prototypes over time, analysis of the captured data showed evolution and major changes in the prototypes. Such data can be used for understanding the process of prototyping and consequently provide means to improve prototype and overall creative performance. We outline a future Protobooth system in terms of functionality.
Future Learning and Design Creativity Competency

Published: July 2019

AbstractIn this study, we discuss a structure for developing the skills and competencies required by the learning framework of the Organisation for Economic Co-operation and Development (OECD) for future education. Given the broad range of skills and the numerous competencies required to meet the demands of future society, the proposed wider and higher-level framework is based on STEAM (science, technology, engineering, art and design, and mathematics) and addresses the limitations of conventional computational thinking by tackling some of the skills and competencies. This is done by proposing the enrichment of STEAM educational approach with art thinking, which may be defined as a creative human-centred discovery process. To explore such enrichment, we conducted a workshop on art thinking. The motivation of the workshop was to explore whether art thinking can overcome some of the limitations of computational thinking regarding future education in the OECD learning framework. We discuss STEAM as focusing on design creativity competency, and we outline the development of educational activities such as workshops to promote competencies in the perspective of OECD framework.
Heuristic Evaluation of Ambient Devices Using Smart Materials
Authors: Marques-Lima Lucas , Faucheu Jenny 
Published: July 2019

AbstractTeaching “calm technology” and “smart materials” as prospective trends in product design is the motivation of the educational workshop presented in this paper. Materials can trigger creative thinking. Indeed, concepts can be generated ideas that come from the encounter with a material showing the material's unexpressed potential. However, a smart material is a complex hybrid object. It is a highly technical matter that requires years of R&D to be developed and matured. It is also a highly social matter, that blurs the traditional boundary between matter and function in a product, creates an experience, and enhances sensations. The workshop presented in this paper is an opportunity for the students to analyze the complexity of user experience related to ambient devices using smart materials. In order to provide a guideline to perform this analysis, an approach based on heuristic evaluation is proposed to the students.
PhD Research Learning in Product Architecture Design

Published: July 2019

AbstractThe field of design research has been expanding into a wide diverse range of multidisciplinary topics. It takes substantial time for young researchers to attain a cumulative overview of state of the art on ever more complex methodologies. Teaching doctoral candidates in summer schools is an approach being taken by the design society to support them attaining an immersed understanding of a chosen research field as well as to help them formulate their own line of research. The aim for a new researcher is to form exchanges and collaborations with other researchers. The 'International Summer School on Product Architecture Design - PAD 2018' was such an effort, where 17 international PhD researchers and three international faculties met for a week and explored research in product architecture through hands-on exercises. We surveyed the researchers for effectiveness of the summer school and found that structure and concept of the summer school was effective for providing a background baseline of state of the art. We found there was a significant but less impact on individual participant´s research. We have yet to understand if the creation of collaborations among participants will occur.
An Integral Design Framework for Multi-Disciplinary Design
Authors: Zeiler Wim 
Published: July 2019

AbstractA comprehensive domain independent system-level perspective of conceptualization of design is a major driver for successful product development. Such a general design model, Integral Design, was developed based on a specific Dutch design method, Methodical design, which was aimed specifically for applications in the Mechanical Engineering domain. The design method was specifically developed with the help of experiences designers and is meant for young students in a multi-disciplinary design context, such as building design. Integral design provides a suitable framework, existing of phases and specific steps, for guiding users through the design process. It support not only the designers but also helps them to make the process explicit and to communicate the actions and results to their stakeholders. The focus in this paper is on presenting the overall frame work of the design method. In the Netherlands in several bachelor and master educational programs at Technical High schools and the University of Technology Eindhoven use this model to teach students mechanical engineering design and building services design. As such it is one of the most popular design method in the Netherlands.

Published: July 2019

AbstractAdditive Manufacturing (AM) processes had an extensively and substantially technological growth over the past years that directly influences the continuously increased and manifold possibilities for processing new and innovative products. However, additively manufactured products mostly are still fabricated with only small adaptions compared to conventional parts, and thus waste many design potentials although specific design guidelines have been widely developed to restrict geometrical deficiencies or suggest improvements in component design.As a result, this contribution furtherly aims to systematically consider AM potentials already on the functional level of product development offering significant but until now still not or just insufficiently exploited potentials. Therefore, the presented approach uses the already proven Design Pattern Matrix (DPM) approach for conventional technologies extended by a concurrent selection of materials and processes specifically for AM. Here, the DPM derives information about the manufacturing process in form of design elements and links them to the function carriers of the product including a methodological determination of requirements.

Published: July 2019

AbstractNew advances in both neurosciences and computational approaches have changed the landscapes for smart devices design serving mobility-related disabilities. In this paper we present the integration of affordable robotics and wearable sensors through our mechatronic product platform, Sparthan, to enable accessibility of the technology in both the power prosthesis and neurorehabilitation space. Sparthan leverages 3rd party EMG sensors, Myo armband, to process muscles sensor data and translate user intention into hand movements. Key innovation includes the modularity, scalability and high degree of customization the solution affords to the target users. User-centered design approaches and mechatronic system design are detailed to demonstrate the versatility of integrative systems and design. What started off as an engineering research endeavor is also positioned to be deployed to deliver real-world impact, especially for prosthesis users in developing countries.

Published: July 2019

AbstractNowadays, topology optimization and lattice structures are being re-discovered thanks to Additive Manufacturing technologies, that allow to easily produce parts with complex geometries.The primary aim of this work is to provide an original contribution for geometric modeling of conformal lattice structures for both wireframe and mesh models, improving previously presented methods. The secondary aim is to compare the proposed approaches with commercial software solutions on a piston rod as a case study.The central part of the rod undergoes size optimization of conformal lattice structure beams diameters using the proposed methods, and topology optimization using commercial software tool. The optimized lattice is modeled with a NURBS approach and with the novel mesh approach, while the topologically optimized part is manually remodeled to obtain a proper geometry. Results show that the lattice mesh modelling approach has the best performance, resulting in a lightweight structure with smooth surfaces and without sharp edges at nodes, enhancing mechanical properties and fatigue life.

“Sacred Trust”: Rethinking Late British Decolonization in Indigenous Canada
Authors: Hebert Joel 
Published: July 2019

AbstractThis article considers the political activism of Canada's Indigenous peoples as a corrective to the prevailing narrative of British decolonization. For several decades, historians have described the end of empire as a series of linear political transitions from colony to nation-state, all ending in the late 1960s. But for many colonized peoples, the path to sovereignty was much less straightforward, especially in contexts where the goal of a discrete nation-state was unattainable. Canada's Indigenous peoples were one such group. In 1980, in the face of separatism in Quebec, Prime Minister Pierre Trudeau pledged to renew the Canadian Confederation by bringing home the constitution, which was still retained by the British Parliament. But many Indigenous leaders feared that this final separation of powers would extinguish their historic bilateral treaties with the British crown, including the Royal Proclamation of 1763 that guaranteed Indigenous sovereignty in a trust relationship with Britain. Indigenous activists thus organized lobbying campaigns at Westminster to oppose Trudeau's act of so-called patriation. This article follows the Constitution Express, a campaign organized by the Union of British Columbia Indian Chiefs in 1981. Maneuvering around the nuances of British political and cultural difference, activists on the Constitution Express articulated and exercised their own vision of decolonization, pursuing continued ties to Britain as their best hope for securing Indigenous sovereignty in a federal Canada.
Revisiting Bolgiano–Obukhov scaling for moderately stably stratified turbulence
Authors: Alam Shadab , Guha Anirban , Verma Mahendra K. 
Published: July 2019

According to the celebrated Bolgiano–Obukhov (Bolgiano, J. Geophys. Res., vol. 64 (12), 1959, pp. 2226–2229; Obukhov, Dokl. Akad. Nauk SSSR, vol. 125, 1959, p. 1246) phenomenology for moderately stably stratified turbulence, the energy spectrum in the inertial range shows a dual scaling: the kinetic energy follows (i) ${\sim}k^{-11/5}$ for $k<k_{B}$, and (ii) ${\sim}k^{-5/3}$ for $k>k_{B}$, where $k_{B}$ is the Bolgiano wavenumber. The $k^{-5/3}$ scaling, akin to passive scalar turbulence, is a direct consequence of the assumption that buoyancy is insignificant for $k>k_{B}$. We revisit this assumption, and using the constancy of kinetic and potential energy fluxes and simple theoretical analysis, we find that the $k^{-5/3}$ spectrum is absent. This is because the velocity field at small scales is too weak to establish a constant kinetic energy flux as in passive scalar turbulence. A quantitative condition for the existence of the second regime is also derived in the paper.
NAPOLEONIC FREEDOM OF WORSHIP IN LAW AND ART
Authors: Cooper Levi 
Published: July 2019

ABSTRACTNapoleon's most famous innovation in his legendary military career was the use of the daunting Grande Armée with an emphasis on speed, maneuverability, and maintaining the offensive. Yet Napoleon understood that while skirmishes were won or lost on the battlefield, the real war lay in public perception. To that end, Napoleon used art and cultural treasures as part of his arsenal in order to create the perception of victory, regardless of the outcome of any particular campaign. Examining contemporary French artistic representations of Napoleon granting freedom of worship to religious groups, this article analyzes artwork as a tool for fashioning and communicating legal narrative. Popular visual arts are mined for meaning, painting a portrait of the legal and cultural setting of these creative works. The partisan artwork demonstrates how Napoleon's artists depicted freedom of worship as the freedom—granted to all faiths—to worship Napoleon. It is noted that Jews feature disproportionately in the Empire period's depictions of freedom of worship. This is surprising, as the Jewish community was numerically insignificant and hardly influential in Napoleon's realm. This article argues that in addition to broadcasting religious tolerance, Napoleonic artwork used Jews and symbols like Moses and tablets of law to fashion a narrative of law that foregrounded the legal legitimacy of Napoleon's rule: Napoleon's regime is legally just; the enlightened ruler affords rights and liberties to all his subjects; divine Napoleon is the new lawgiver.

ABSTRACTDeciduous tree leaf and grass samples were collected in Debrecen, the second largest city in Hungary. The aim of the study was to determine the rate of fossil fuel-derived carbon in urban vegetation. At the locations sampled, C3 and C4 plants close to roads were collected in September 2017. In total, 82 tree and grass leaf samples were gathered at 36 different sampling points all over the city of Debrecen. The radiocarbon (14C) results of the samples were compared to the local urban background atmospheric 14CO2 data to determine the percentage of the fossil fuel-derived carbon in the plants. Based on our results, the average fossil carbon content in the tree and grass leaf samples were 0.9 ± 1.2% and 2.5 ± 2.5%, respectively. The highest fossil carbon content was 9.6 ± 0.6% in a grass and 4.7 ± 0.7% in a tree leaf sample. It appears that the negative fossil carbon content results obtained at urban sampling areas reflect modern carbon emission, where radiocarbon content is higher than the corresponding local background, presumably due burning of recent wood containing bomb 14C in the suburbs as well as other possible sources such as litter decomposition or soil CO2 emission.
Optimal Control and Path Planning of a 3PRS Robot Using Indirect Variation Algorithm
Authors: Tourajizadeh H. , Gholami O. 
Published: July 2019

SUMMARYIn this paper, optimal control of a 3PRS robot is performed, and its related optimal path is extracted accordingly. This robot is a kind of parallel spatial robot with six DOFs which can be controlled using three active prismatic joints and three passive rotary ones. Carrying a load between two initial and final positions is the main application of this robot. Therefore, extracting the optimal path is a valuable study for maximizing the load capacity of the robot. First of all, the complete kinematic and kinetic modeling of the robot is extracted to control and optimize the robot. As the robot is categorized as a constrained robot, its kinematics is studied using a Jacobian matrix and its pseudo inverse whereas its kinetics is studied using Lagrange multipliers. The robot is then controlled using feedforward term of the inverse dynamics. Afterward, the extracted dynamics equation of the robot is transferred to state space to be employed for calculus of variations. Considering the constrained entity of the robot, null space of the robot is employed to eliminate the Lagrange multipliers to provide the applicability of indirect variation algorithm for the robot. As a result, not only are the optimal controlling signals calculated but also the corresponding optimal path of the robot between two boundary conditions is extracted. All the modeling, controlling, and optimization process are verified using MATLAB simulation. The profiles are then double-checked by comparing the results with SimMechanics. It is proved that with the aid of the proposed controlling and optimization method of this article, the robot can be controlled along its optimal path through which the maximum load can be carried.
Reunited after 1000 years. The development of definite articles in Icelandic
Authors: Pfaff Alexander 
Published: July 2019

AbstractThis article traces the diachronic development from the Proto Norse demonstrative hinn via the Old Icelandic definite article(s) to the Modern Icelandic article system. This demonstrative gave rise to two distinct article elements during the Viking period that are well-attested from Old Icelandic onwards, a freestanding and a suffixed article.Based on evidence from Old Icelandic, I argue for a categorial distinction between an adjectival and a nominal article, which does not entirely coincide with a mere morpho-phonological distinction. The former, which mostly occurs as a freestanding element, is a genuine component of AP, not an immediate constituent of the nominal extended projection. The latter, which only occurs in suffixal form, heads a low projection in the extended nominal projection and has scope only over the noun. For Modern Icelandic, on the other hand, I will adopt the idea that free and suffixed articles are two surface manifestations of the same element.The diachronic perspective is complemented by an examination of the development of seven adjectivally modified definite noun phrase patterns. This empirical survey reveals several surprising facts: The standard pattern of modification in Modern Icelandic was virtually non-existent prior to the 17th century, and double definiteness persisted until the early 20th century. Likewise, certain modificational patterns otherwise found in Mainland Scandinavian were dominant between the 16th and 19th century. This latter observation points to a competition between two adjectival articles hinn vs. sá similar to the one that had taken place earlier in Mainland Scandinavian. In Icelandic, however, sá did not replace hinn, and, in the long run, a pattern not comprising an adjectival article became the dominant one.
