1. 6. Challenges and Advantages of Stratified Combustion in Gasoline Direct-Injected Engines

   Författare :Anders Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particulate Mass; SGDI; Particulate Number; Direct-Injected; GDI; Particulate Sampling; Spray-Guided; Particulates; Stratified Charge; Gasoline; DI;

   Sammanfattning : The modern world is based on an extensive transport network in which passenger vehicles play a major role. Although passenger vehicles have improved significantly in recent decades, they still contribute to the pollution of our environment and global warming. Consequently, new ways of reducing their emissions are needed. LÄS MER

3. 7. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

   Författare :Göran Almkvist; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

   Sammanfattning : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. LÄS MER

4. 8. Integrated Product and Production Platforms for Pharmaceutical Products: Design Thinking for the Development of Personalized Medicines

   Författare :Maria Daniela Irene Siiskonen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Integrated product and production platforms; Personalized medicines; Mass customization;

   Sammanfattning : Treatments, when customized according to individual patient attributes, are in recent years referred to as personalized medicines. Personalized medicines aim at improving the therapeutic outcome of the patient. However, current pharmaceutical production is dominated by mass production in a batch manner, i.e. LÄS MER

5. 9. Digital model-driven retail supply chain management

   Sammanfattning : The purpose of this thesis is to increase the understanding of how matching of digital models of products and customers can be used to shift the performance frontier in retail supply chains. This thesis puts forward the matching of digital models as an operational practice used by retail supply chains. LÄS MER

7. 10. 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.
