Let’s step into each other’s worlds: designing for local transformation processes
Get PDFIn our densely-populated cities, fostering harmony between differing communities is an increasingly difficult art, and one in which design can provide positive contributions. This paper describes a design project which aimed to decrease tensions between youth and residents in a city neighbourhood through an empathy-building process. Individuals from both groups were guided through the process of stepping into each others’ worlds (through Virtual Reality) and developing solutions together to address points of tension. Their individual transformative processes were tracked in order to make the implicit outcomes of such design processes explicit. Throughout this process new dynamics and connections emerged, revealing grounds for structurally decreasing tensions and promoting participatory approaches for local transformation processes. This paper describes the project and presents our learnings regarding (1) the transformative impact on the involved individuals from the neighbourhood and (2) reflections on the contributing roles of the designers in social innovation projects
A Study of Product Service System for Product Family Based on Extension Design
Get PDFThis paper, from the perspective of extension design, investigates the product family architecture composed of demand domain, functional domain, technology domain, and physical domain and establishes a product service system, which is centered on the product family development platform, based on the extension innovation method. The basic-element logic language and method of extension design is employed to analyze the characteristics of product family design including generalization, parameterization, modularization, and intelligence. In this paper, the product family design platform, including four models and three resource libraries, is developed through the formalized and modeled basic-element representation, configuration of modular elements, and intelligent generation path. Combined with artificial intelligence technology, this research constructs a smart product service system framework oriented towards product family design and proposes an extension design generation system
Peeling Back the Layers: Prototyping Systemic Transformation through the Circular Food Innovation Lab
Get PDFWasted food — the result of a linear pattern of producing, under-consuming and disposing of food — is a pervasive issue globally and in Canada. Wasted food is a complex challenge, meaning it is characterized by unpredictability, ambiguity, and many actors. The current climate crisis, food insecurity, economic disparity and housing inequality all intersect with this challenge. If we are to tackle these increasingly complex issues in social and public sectors, we need to work together in new and emergent ways. The Circular Food Innovation Lab was a unique research initiative that drew together municipal government, interdisciplinary designers and regional food businesses – grocers, food producers, distributors, restaurants and vendors – to tackle these complex challenges through systemic and service design methodologies, asking “how might we work together to increase circularity in Vancouver’s food system so that food is not lost or wasted; access to food is nourishing, equitable, and culturally appropriate; and habitats are protected for current and future generations of humans and more-than-humans?
A study of Chinese residents participating in design for sustainability in the context of carbon neutrality
Get PDFThis paper combs the development history and current situation of Design for Sustainability (DFS), and discusses the role of DFS in social transformation. The author studies the methods and tools of DFS and their achievements in different fields. The research shows that DFS can provide effective solutions in different fields. In the article, the author finds that the DFS policy will be different in different contexts, so the author puts forward the DFS method in the Chinese social context. Under the severe theme of climate change, the research is focused on the issue of carbon emissions. Using the DFS method in the context of Chinese society, the author takes the design of sustainable service system for kitchen waste recycling as a case, and tries to introduce the DFS method into the problem of reducing carbon emissions
The Design as intragroup conflict mediator
Get PDFService Design presents new challenges in its practice as we widen the complexity of its activity scope. Among the many issues to be dealt with, complexity may be associated to carrying out multidisciplinary workgroups, where people from different areas of a company, social group leaders, specialists with specific knowledge, all have a say during the group process by applying their technical skills and distinct viewpoints to solve a problem. The dialectics that happen in such work debates generate conflict situations, which can be interesting creative drivers, thus requiring the designer to uphold a specific expertise to mediate them. This article proposes a course of action to mediate intragroup conflict in Service Design projects, supported by knowledge from the fields of Group Psychology and Topological Psychology
UX Sustainability: an overview on the sustainability dimension of AI-infused Objects forming product-service ecosystems
Get PDFThis research aims to suggest a new design perspective to analyse the sustainability of an AI-infused object in its entirety. Before we present what AI-infused Objects are and how they form product-service ecosystems, secondly, we analyse the state of the arts of its sustainable dimension. The analysis of AI-infused objects should include: (1) the entire life cycle of the object, its social and economic impact; (2) the impact of the "digital soul" of the object; (3) the ecosystem analysis should also include all indirect impacts of the service, considering how users' behaviour changes when they come in contact with the artificial intelligence ecosystem. The research contributes to the design literature in two ways: (1) by raising awareness in designers on the effective impact of AI-infused Objects forming the product-service ecosystems, (2) by inviting designers to make this awareness concrete through User Experience Sustainability analysis and behavioural change strategies applied to persuasive technology
WebLicht-Batch -- A Web-Based Interface for Batch Processing Large Input with the WebLicht Workflow Engine
Get PDFWebLicht is a workflow engine that gives researchers access to a well-inhabited space of natural language processing tools that can be combined into tool chains to perform complex natural language analyses. In this paper, we present WebLicht-Batch, a web-based interface to WebLicht's chainer back-end. WebLicht-Batch helps users to automatically feed large input data, or input data of multiple files into WebLicht. It disassembles large input into smaller, more digestible sizes, feeds the resulting parts into WebLicht's pipelining and execution engine, and then assembles the results of such processing into files that preserve the usual input-output dichotomy
On the Combination of Cryptography and Steganography in 17th Century Germany
Get PDFAssessing and averting possible interception lies at the heart of cryptology. In handbooks printed in 17th century Germany, the authors suggested combining steganography and cryptography to increase information security. This article discusses several techniques for concealing ciphers and demonstrates that the authors of instructional literature had to consider complex interplaying factors when it came to combining cryptography and steganography. Overall, these examples show that the cryptological literature of the 17th century mirrors an increased discussion about the visibility of ciphers
Simulation of the on-orbit construction of structural variable modular spacecraft by robots
Get PDFThis paper gives an overview on the simulation of the on-orbit construction of structural variable modular spacecraft by robots using Modelica. For this purpose, a new concept using so-called tensor bodies was developed which enables the fast and continuous simulation of complex scenarios even during structural changes. This research was part of two ESA and EU projects. An overview of the modeling and simulation approach will be given. The scenarios include the on-orbit re-configuration of a modular satellite with a walking robot manipulator and the construction of a modular space antenna array platform with a walking robot with two arms and a torso
Power System Real-Time Simulation using Modelica and the FMI
Get PDFReal-time digital simulation of power systems is incredibly important for the testing of appropriate control and protection strategies in the power system industry. However, the case in which one single model can be used in offline simulations and then for testing in realtime studies is rare, if existing at all, due to the lack of adequate standard development in the power industry or the adoption of successful standards elsewhere. A direct consequence of this lack of portability is the large amount of time and resources spent in re-implementation and validation of models for real-time simulation of power grids. The present study proposes the usage of Modelica and the FMI standard in order to address this issue. To test the proposed approach, power system models are built offline using the OpenIPSL library and are exported as FMUs. Real-time simulations of two typical power system models are performed using dSPACE SCALEXIO™, proving that the proposed framework using Modelica and the FMI can greatly contribute to the enhancement of today’s current practice in the power industry by providing portability and tractability between offline and real-time power system models
