A computer-based product classification and component detection for demanufacturing processes

This is an Author's Accepted Manuscript of an article published in International Journal of Computer Integrated Manufacturing, 24(10), 900-914, 2011 [copyright Taylor & Francis], available online at: http://www.tandfonline.com/10.1080/0951192X.2011.579169.The aim of this paper is to propose a novel computer-based product classification, component detection and tracking for demanufacturing and disassembly process. This is achieved by introducing a series of automated and sequential product scanning, component identification, image analysis and sorting – leading to the development of a bill of material (BOM). The produced BOM can then be associated with the relevant disassembly/demanufacture proviso. The proposed integrated image sorting and product classification (ISPC) approach can be considered as a step forward in automation of demanufacturing activities. The ISPC model proposed in this paper utilises and builds on the state-of-the-art technology and current body of research in computer-integrated demanufacturing and remanufacturing (CIDR). An appraisal of the latest research material and the factors that inhibit CIDR methods inpractice are presented. A novel solution for the integration of imaging and material identification techniques toovercome some of the existing shortcomings of automated recycling processes is proposed in this paper. The proposed product scanning and component detection ISPC software consists of four distinct models: the repertory database, the search engine, the product-attributes updater and the image sorting and classification algorithm. The software framework that integrates the four components is presented in this paper. Finally, an overall assessment of applying ISPC at various stages of CIDR processes concludes the article.University of Ibadan MacArthur Foundation Gran

Social and interpersonal approaches to design for behaviour change

Copyright @ 2012 Social Science Electronic PublishingThis paper reviews a diverse set of social and interpersonal infl uence approaches and techniques which could be relevant to designers seeking to infl uence behavior change for social and environmental bene fit. These include work on social proof (which already has some practical applications in household energy use reduction studies) and dramaturgical and contextual approaches to modelling interaction. Perspectives on interpersonal infl uence are also covered, such as techniques extracted from Dale Carnegie's 'How to Win Friends and In fluence People', and a brief dive into the world of neuro-linguistic programming. In each case, implications for designers are highlighted and summarized at the end of the paper

Fashion\u27s Destruction of Unsold Goods: Responsible Solutions for an Environmentally Conscious Future

Over the past two years, headlines of fast-fashion and luxury brands burning their merchandise have flooded media outlets. While this came as a shock to the general public, it has actually been a standard industry practice for decades. As societal norms are leaning more towards environmentally conscious practices, destroying unsold products is no longer viewed as an acceptable option. Brands are facing increased scrutiny related to their environmental impact—such as the amount of textile waste that ends up in a landfill—and how they address the issue. While the media have criticized brands for these practices, they have not suggested long-term solutions to resolve the problem. Brands are left in the dark without a road map showing them how to modernize their systems. Furthermore, when governments introduce new bills focused on textile waste, brands experience added pressure. France is in the process of requiring brands to recycle or reuse their unsold goods by January 2020. However, there is no one-size-fits-all solution for any brand or country: what may work for a fast-fashion brand will not necessarily work for a luxury brand. In the same vein, what may work for France may not work for the United States. This Note explores a number of potential solutions to this problem which range from legal solutions, to reusing, manufacturing, technological, and crisis management solutions. Brands must start to address this issue within their supply chain in a thorough and transparent manner, as this is not a fleeting trend

Physiologically attentive user interface for improved robot teleoperation

User interfaces (UI) are shifting from being attention-hungry to being attentive to users’ needs upon interaction. Interfaces developed for robot teleoperation can be particularly complex, often displaying large amounts of information, which can increase the cognitive overload that prejudices the performance of the operator. This paper presents the development of a Physiologically Attentive User Interface (PAUI) prototype preliminary evaluated with six participants. A case study on Urban Search and Rescue (USAR) operations that teleoperate a robot was used although the proposed approach aims to be generic. The robot considered provides an overly complex Graphical User Interface (GUI) which does not allow access to its source code. This represents a recurring and challenging scenario when robots are still in use, but technical updates are no longer offered that usually mean their abandon. A major contribution of the approach is the possibility of recycling old systems while improving the UI made available to end users and considering as input their physiological data. The proposed PAUI analyses physiological data, facial expressions, and eye movements to classify three mental states (rest, workload, and stress). An Attentive User Interface (AUI) is then assembled by recycling a pre-existing GUI, which is dynamically modified according to the predicted mental state to improve the user's focus during mentally demanding situations. In addition to the novelty of the proposed PAUIs that take advantage of pre-existing GUIs, this work also contributes with the design of a user experiment comprising mental state induction tasks that successfully trigger high and low cognitive overload states. Results from the preliminary user evaluation revealed a tendency for improvement in the usefulness and ease of usage of the PAUI, although without statistical significance, due to the reduced number of subjects.info:eu-repo/semantics/acceptedVersio
