1. 6. Industrial Application of Set-based Concurrent Engineering – Managing the design space by using Platform System Families

   Författare :Dag Raudberget; Hans Johannesson; Durvard K Sobek; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product development; platform-based development; set-based concurrent engineering; design decisions; functional modelling; configurable components; platform architecture; system family;

   Sammanfattning : During product development, most of the customer value, as well as the cost and the quality of a product are defined. This key role of development in industry has led to an intense search for better ways to develop products, software, services and systems. LÄS MER

3. 7. Platform Design for Producibility: Early-Stage Modeling and Assessment Support

   Författare :Jonas Landahl; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems engineering; Mass customization; Platform design; Reuse of design and production information; Enhanced function-means modeling; Set-Based Concurrent Engineering; Producibility assessment; Variety;

   Sammanfattning : In industry, platforms are commonly adopted to reduce unique parts among a variety of distinct product variants, which have proven to be cost-effective within a single platform lifecycle. However, when the platform becomes obsolete or modifications are required to capture changing customer and production needs and requirements, manufacturers often spill tears over the time-consuming and costly processes of reusing and adapting the current platform structure into new.

4. 8. Aircraft Systems Conceptual Design : An object-oriented approach from to

   Författare :Ingo Staack; Petter Krus; Frank Thielecke; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aircraft Conceptual Design (ACD) is facing new challenges on the way to enhanced fidelity level required of the nowadays complex system design. Namely the integration of models and simulations of different fidelity levels to enhance the analysis capability while maintaining a streamlined, transparent, and low cost working process is required.

5. 9. Integrating a Strategic Sustainable Development Perspective in Product-Service System Innovation

   Författare :Anthony Thompson; Blekinge Tekniska Högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable product innovation; Sustainable product development; Strategic sustainable development; Product-service systems PSS ; Life cycle management; Set-based product development;

   Sammanfattning : There is an intersection of challenges where society’s social and ecological problems coincide with the industrial firm’s challenge to maintain profitability in a globalizing world. Products connect these challenges. LÄS MER

7. 10. Peak and Power Reduction in Multicarrier Communication Systems

   Författare :Niklas Andgart; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; line driver; Signal processing; Signalbehandling; Telecommunication engineering; power reduction; DSL; DMT; tone reservation; PAR; Peak to average ratio;

   Sammanfattning : Broadband multicarrier communication suffers from a large signal span, causing problems in both wireless and wireline systems. This is commonly referred to as a high peak to average ratio (PAR), and leads to a high power consumption, which is an important limitation in many communication systems. LÄS MER
