1. 16. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems

   Författare :Parastou Kharazmi; Folke Björk; Tord af Klintberg; Tor Broström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. LÄS MER

3. 17. Transport service triads in supply networks

   Författare :Victor Eriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; performance; embeddedness; network; supply chain; service; freight; transport; triad; relationship; sustainability;

   Sammanfattning : This doctoral thesis deals with the embeddedness of transport services in supply networks. The exchange of transport services depends on the exchange of goods since exchange of goods generates demand for transport services. LÄS MER

4. 18. Fatigue improvement of steel bridges with high-frequency mechanical impact treatment

   Författare :Poja Shams Hakimi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HFMI; thickness effect; bridge; steel; variable amplitude; fatigue;

   Sammanfattning : This thesis investigates the performance of fatigue-improved welds with high-frequency mechanical impact (HFMI) for application on new bridges. Fatigue strength improvement with HFMI can enable lightweight design of bridges and allow the utilisation of the benefits of high-strength steels. LÄS MER

5. 19. User-Centred Design and Technology-Mediated Services- Identifying and Addressing Challenges by Analysing Activities

   Författare :Oskar Rexfelt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology-mediated services; product development; user requirements; User-centred design; service development; user studies;

   Sammanfattning : User-centred design has a focus on designing products to satisfy user needs rather than emanating from a technological starting point. Understanding user needs when developing products is considered a key component to achieve market success today.User-centred design is almost always described as a way to design products that satisfy user needs.

7. 20. Towards Changeability Quantification for Product-Service Systems Design

   Författare :Raj Jiten Machchhar; Alessandro Bertoni; Johan Wall; Fredrik Elgh; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Changeability quantification; early design; Uncertainty; Value robustness; Operational Scenario; Product-Service Systems; Systems Engineering.; Maskinteknik; Mechanical Engineering;

   Sammanfattning : Tough competition and volatile global markets have pushed the manufacturing industries to develop solutions more customer-centric with optimal utilization of resources. One of the key reasons behind developing a customer-centric solution is the increased customer value that imparts a competitive edge to the manufacturing industries, eventually leading them to sustain their businesses.
