1. 1. Scrap happens, but does it have to? On the potential of increasing machine component reuse

   Författare :Derek Diener; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; component; circular economy; obsolescence; remanufacturing; reuse;

   Sammanfattning : The vision of the “circular economy” provides some guidelines for society to strive towards. In the circular economy, material resources are used and reused and recycled better, if not endlessly. Products are to require less material and deliver more function. LÄS MER

3. 2. Circular Business Models that Extend Product Value : Going Beyond Recycling to Create New Circular Business Opportunities

   Författare :Katherine Whalen; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular business model; product life extension; obsolescence; circular economy; business model; reuse; repair; refurbishment; sustainability strategies; sustainability education;

   Sammanfattning : Over the past ten years, significant industry, policy, and scientific attention has been given to the ‘circular economy’, which aims to create a more sustainable society by decoupling economic growth from resource consumption. Firms are expected to play a significant role in the shift to a circular economy model by implementing circular business models that encourage prolonged use of products, components, and materials.

4. 3. Unwrapping Cobol : Lessons in Crisis Computing

   Författare :Linda Hilfling Ritasdatter; Susan Kozel; Maria Hellström Reimer; Florian Cramer; Nishant Shah; Malmö universitet; []
   Nyckelord :Crisis; Execution; Maintenance; Cobol; Automation; Global Flows; Y2K; Human Factor; Outsourcing; Development; Legacy Systems; Programming Languages; History of Computing; HCI; Software Wrapping; Postcolonial Studies; Diffraction; Broken world thinking; Grace Hopper; Media Archaeology; Debugging; Zombie Media; Obsolescence; Technological Development; Unsettling Ontologies; Fourth Industrial Revolution; Artificial Intelligence; Interaktionsdesign; Interaktionsdesign;

   Sammanfattning : By engaging with COBOL, a detested and would-be obsolete programming language, the dark sides of automation are examined in this thesis: hidden workforces and computational infrastructures that are, in reality, central to the execution and maintenance of global economic and informational flows. Frictions within these flows are made more visible in moments of crisis when asymmetrical power structures are surfaced, as demonstrated in an analysis of the infamous Y2K Bug, its connection to the outsourcing boom in India and the legacy of COBOL.

5. 4. Technology Driven Obsolescence Management for Embedded Systems

   Författare :Xiaozhou Meng; Benny Thörnberg; Mattias O'Nils; Jim Tørresen; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Long life cycle; embedded system; DMSMS; obsolescnece; FPGA; IP; portability;

   Sammanfattning : In this thesis, the work presented is in relation to technology driven obsolescence management for embedded systems.Component obsolescence problems may occur in systems with a life cycle longer than that of one or more of their components when there is a demand without enough existing stock, such as automotive, avionics, military applications, etc. LÄS MER

7. 5. On the ECO2 multifunctional design paradigm and tools for acoustic tailoring

   Författare :Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Per Wennhage; Franck Sgard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle design; planned obsolescence; anisotropy; porous materials; sound absorbing materials; acoustic modelling; power balance; energy assessment; dissipated power.; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : Nowadays vehicle design paradigm influences not only the effectiveness of the different means of transport, but also the environment and economy in a critical way. The assessment of the consequences that design choices have on society at large are necessary to understand the limits of the methods and techniques currently employed. LÄS MER
