1. 41. Fatigue strength of welds in 800 MPa yield strength steels : Effects of weld toe geometry and residual stress

   Författare :Ebrahim Harati; Lars-Erik Svensson; Leif Karlsson; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue strength; Residual stress; Welds; Weld toe geometry; High strength steel; Weld Impression Analysis; Laser Scanning Profiling; Structured Light Projection; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Nowadays there is a strong demand for lighter vehicles in order to increase the pay load. Through this the specific fuel consumption is decreased, the amount of greenhouse gases is lowered and the transport economy improved. One possibility to optimize the weight is to make the components from high strength steels and join them by welding. LÄS MER

3. 42. Discrete-Event Simulation, Operations Analysis, and Manufacturing System Development: Towards Structure and Integration

   Författare :Lars Holst; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integration; Manufacturing System Development; Discrete-Event Simulation; Production technology; Produktionsteknik;

   Sammanfattning : After more than four decades of presence in the manufacturing industry, discrete event simulation has established itself as a powerful technology for a wide range of strategic, tactical, and operational applications in production, logistics, and supply chain management. Discrete event simulation software packages - although not entirely adequate - are relatively capable, and methodologies for performing simulation projects are reasonably well-developed and documented.

4. 43. The HCCI Engine – High Load Performance and Control Aspects

   Författare :Jan-Ola Olsson; Förbränningsmotorer; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; Motors and propulsion systems; Motorer; framdrivningssystem; Real Time; Black-Box Model; LQG; Closed-Loop Control; Internal Combustion Engine; Emissions; EGR; Efficiency; HCCI; Homogeneous Charge Compression Ignition;

   Sammanfattning : Current combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. LÄS MER

5. 44. Requirements-Driven Product Innovation - Methods and Tools Reflecting Industrial Needs

   Författare :Lars Almefelt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design methodology; requirements management; concept development; product modelling; innovation; teamwork; Automotive industry;

   Sammanfattning : Product development in the automotive industry is typically characterised by cross-functional teamwork. At the same time, the organisation and development culture are in many ways component-oriented and indeed, highly advanced from the point of view of component development. As a result, most components themselves are relatively mature. LÄS MER

7. 45. Rural Development and Territorial Dynamics in the Province of Misiones, Argentina

   Författare :Andrea Nardi; Institutionen för kulturgeografi och ekonomisk geografi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Rural development; territorial dynamics; Misiones; Argentina; family agriculture; alternative development; Territory; Agroecology; Farmers markets; Seed markets;

   Sammanfattning : During the 1990s, Latin America went through important structural transformations. The continent experienced a profound alteration in the relations between the state, society, market and natural environment. LÄS MER
